One of fundamental advantages of Open Source is that finding bugs generally occurs much faster. Plus, as a user you have direct access to the bug tracking system (bugzilla, in this case at http://nagoya.apache.org/bugzilla/ ). There are currently 90 open bugs for Struts. How do I know this? I just looked - it's on-line for everyone to see. If you find a bug, you can add one yourself and someone with appropriate rights in bugzilla will have to address it before it dissapears - it's an extremely 'open book' approach that no vendor would dream of giving you. I've worked for software companies and we would NEVER have opened our bug lists - our competitors would have printed them out and used them against us in sales calls. Eric Raymond, in his essay The Cathedral and the Bazaar says that ``Given enough eyeballs, all bugs are shallow.'' And, at least, that they turn shallow pretty quickly when exposed to a thousand eager co-developers pounding on every single new release. This is why Linux is more stable than NT and Apache dominates the web server market - it's not because it's free, it's because it's BETTER and FREER of BUGS. If I were your boss, I'd worry more about the quality of commercial software than I would about open source. If your manager is concerned about using Open Source becuase of software quality, then get them a copy of Eric's book: The Cathedral and the Bazaar - it's a very short and easy read.

Re: Off-Topic: JMS Design Question...
At 09:14 AM 7/9/2002 -0700, you wrote: Hello, We need to send XML messages (as well as other types of messages) back forth between two Application Servers. In other words, a Web Application created by us will send a message to the application server of our client and vice versa. snip snip snip Just out of curiosity, are you sure you want to use a Topic instead of a Queue? It sounds like you're using 1-1 mapping which is pretty much what Queue's are designed for. snip snip 1) If Client's App Server is down, then our MDB should keep resending till the message is sent successfully. How can I do this in JMS? Queues or Durable Subscriptions will do the trick here. The whole point of JMS is fire and forget. So once the JMS server successfully receives the message you forget about it and delegate that responsibility to the JMS server. 2) If our JMS Server is down (shouldn't happen, but let's say it does) what should the Web App do? Would Durable Subscriptions help in this case? Depends on when the JMS server went down. And what you mean. If you mean that the JMS Server goes down before delivery to the target app server, then yes. If you mean that the JMS server goes down, what do you do with the messages you wish to send during the down time... then no, you'll either have to implement your own internal buffer to try to see if you can get the JMS server restarted before the buffer fills... or if it does or you don't want to do the buffering you're going to have to figure out some sort of state transfer method to get the messages between the app servers back in sync. One method that people do is when the JMS server comes back online is to immediately start receiving messages in the background while you get a 'state transfer'... then once you get the state transfer you start applying the received messages to your system until you catch up. I would greatly appreciate any input in this matter. Thanks (a lot) for your time. I don't know how heavy of an app server you're looking to use, but another alternative is using the Message Driven Objects paradigm that the Apache Messenger project uses. I've used it and love it. It's in the commons sandbox and you'll want to grab a nightly build. Although there isn't a 1.0 release yet, the API is considered stable since the author uses it in many of his own apps.

RE: change an Actionform
Hi Sven, I can't see the action-mapping for the edit - 'billing/FibuAccountGruppeUpdateAction'. This is where the problem will lie. The edit mapping will specify which form should be used, its scope and the key to store it under. When you create the form in your search action you need to put it in the correct scope - request or session and use the key specified in the struts-config. The code : request.getSession().setAttribute(mapping.getName(),myForm); want work as its putting the form under the wrong key, ie the key is SearchForm I'm guessing it should be EditForm. The reason the form bean is blank on the edit form is that Struts has created a form for you as it couldn't find one the specified scope. Hope this helps.

RE: Problem with session ojects: memory size, updates
Hi, Your English is a hell of a lot better than my French...Your question is one that comes up a lot on the list try a search at: http://www.mail-archive.com/struts-user@jakarta.apache.org for 'session size'. One pertinent post is: http://www.mail-archive.com/struts-user@jakarta.apache.org/msg34592.html In short, the answer to what should go in the session depends on how your application will be used. If you expect a *very* high number of concurrent users your session should be under 4k (taken from iAS, WebLogic and WebSphere docs, white papers etc). It will also depend on your hardware, how much RAM is available, network bandwidth, database size/speed etc. If you can predict the highest level of concurrent users, multiple your maximum session size by this. The result will be the amount of RAM taken up by all the sessions put together, if you have sufficient RAM to handle this and all over requirements, then the session size is not an issue. Note however that the number of users can explode unexpectedly, so the best practice recommendation is to keep session size as small as possible. As for the speed of looking up objects from the session, this will depend on your app server, when clustering some app servers will store the session in a db or other persistent store, lookups in this case are relatively expensive. If you are not clustering, I wouldn't worry about the speed of the lookup (even if you are I wouldn't worry about it that much - its not a bottle neck I've ever come across.) Jon Ridgway -Original Message- From: Heligon Sandra [mailto:[EMAIL PROTECTED]] Sent: 11 July 2002 15:12 To: '[EMAIL PROTECTED]' Subject: Problem with session ojects: memory size, updates Sorry, my english level isn't very good. I read that the Struts framework doesn't make (oblige) to use one particular model implementation (EJB, JavaDataObject, JavaBean, ...). But the JavaBean solution is understood or greatly recommended, isn't it ? Because struts uses JSP to display data and JSP pages use JavaBean tags. If we work whit XML representations of remote business objects, is it better to use struts XSL tags rather than generate JavaBean from the XML description ? The XSL solution requires to know XSL tags and is slower and more complex. With JavaBean solution I am frightened having memory or request time problem. The user does a request, the selected Action gets business data from the enterprise tier, generates one or several JavaBean instances and stores the JavaBean in the HttpSession. But the HttpSession size will grow quickly. It is difficult to know when we have to store data in request scope or session scope. Has somebody advices about this dilemma? I am tending to put data systematically in HttpSession in order to reduce network traffic if the user ask again this page. What is the max size of the session objects ? If we user rights on the business objects, we will have the same JavaBean in several HttpSessions. What do you think about this problem ? A last question if we have numerous session objects, when we will have to update one of them it will be very slow to find it in the list. Do you have advices about that ? Is the JavaBean/HttpSession solution realistic with real-time data?

RE: Should I bother to try and handle this with struts?
Hi Rick, The Action classes in struts are designed to encapsulate you business logic.

I'm confused how I can/should handle this in Struts... What I need to build (and long story why) is a User Administration utility and where I'm having trouble fitting this in with struts is in regard to the following: Picture a case where you want to give user's certain roles based on certain applications. So you'd have: BackofficeApp[ select options of possible roles ] JoeBlowApp [ select options of possible roles ] DumbApp [ select options of possible roles ] The problem is the list of applications is dynamic so I can't hard code these values into a form bean or in my dynamicActionForm. Currently I'm planning on doing this an old fashioned way where after submission I'll loop through the same dynamic list of applications and pull up the request parameters based on the values I get back. So for example somewhere I'd end up doing: //while loop through applications String appValue = request.getParameter( appNameBasedOnCurrentLoopValue ); //update db for this app name based on value //continue loop Can I have a form bean gather all this data? Or should I just continue to do it the way I'm doing it?

RE: Really dynamic forms
Hi Olivier In your case you could have an action create and populate an ArrayList with empty passenger objects, add the list to a form, put the form into scope and forward to a jsp.

Contrary to DynaActionForm which are rather declarative forms than dynamic forms, I have a need for building forms that are parametric. For instance, the Internet user specifies the number of elements he requires, and the system builds dynamically a JSP form containing as many fields as the given number. For instance, for a trip, he gives the number of passengers (let's say 3) and the next form he sees contains 3 fields named for instance passengerName1, passengerName2 and passengerName3. Since I don't know how many fields there will be, how can I design an ActionForm handling this ?

RE: where can caching help performance?
Hi Jamie, Even when using Struts there is nothing stopping you writing a custom tag lib to do a db lookup for your portals content, based I guess upon a user preference held in the session/request. You could then use the caching tags you describe. Also remember that most dbs have very good configurable caching mechanisms of their own. Also remember that in J2EE some CMP implementations will give you some free caching (also TopLink/CocoBase etc.) You could code your own mechanism that wraps objects placed in the session with a time stamp and only look them up again if a specified time has elapsed... Judicious use of the Singleton pattern can also speed performance. Jon Ridgway -Original Message- From: Jamie J [mailto:[EMAIL PROTECTED]] Sent: 11 July 2002 20:51 To: [EMAIL PROTECTED] Subject: where can caching help performance? I'm wondering how people speed up their MVC webapps. Taglibs for caching parts of jsps seem like a good way of improving the speed of a web app (see: http://jakarta.apache.org/taglibs/doc/cache-doc/intro.html, http://www.opensymphony.com/oscache/tags.html, the one that comes with weblogic etc). e.g. (pseudo-tag): foo:cache timout=5mins !-- query the database and display details of the 10 most recent news items, or something -- /foo:cache However they don't help much if you've got an MVC app, because all your database access etc happens before the view of it is rendered, as opposed to as it is rendered which is where these taglibs are useful. Is the only option with MVC to cache the data? The idea of caching the rendering of it too is appealing - if they data hasn't changed, why keep re-rendering it? (assuming everyone's view of it is the same). It is particularly appealing when you consider that it can be done with no code changes - you can put a (servlet 2.3) filter in front of servlets/jsps you wanted cached. Its portal-style applications that I'm thinking of here, where you have discrete components of a page which all may involve some database (or other timeconsuming) activity, but the data doesn't change often so the cached view of it can be updated every X-minutes or so. What approaches do people use to speed up such apps? Is caching really only an option in the model, rather than the view? (assuming its not the whole page you're caching). -- jamie __ Do You Yahoo!?

Re: How to automaticlly set the locale according to user's request
Struts Newsgroup (@Basebeans.com) [EMAIL PROTECTED]: Now the question is: 1.I want to setLocale() by the value get from request.getLocale(), but how can I set the struts to automaticlly finish this process. This happens automatically, I think, if you don't override it by setting the Action.LOCALE_KEY attribute on the session. 2.How can I set the web to make jsp also automaticlly encoding the content using the client locale setting. If you mean, how can I change the output language based on the browsers' locale settings?, then the answer in Struts 1.0, is that you can use the bean:message tag to look up a language dependent text from a resource bundle. Eg. if you have the file MyResources.properties containing helloworld=Hello World! and the file MyResources_no.properties containing helloworld=Hei Verden! both at the top level of the WEB-INF directory, and put servlet ... init-param param-nameapplication/param-name param-valueMyResources/param-value /init-param ... /servlet in the web.xml file, then using bean:message key=helloworld/ will render the text Hei Verden! if the browser's locale is no, and Hello World! for all others.

RE: Problem with session ojects: memory size, updates
Thanks John for your response, I have already read the message http://www.mail-archive.com/struts-user@jakarta.apache.org/msg34592.html but I would like to have more details with real examples. I believe that the best way is to try. I read that objects in the session must be removed unlike the request objects. Is it good to do that when the application invalidates the session ?. Because we save objects in the session in order to access data during all the session life. I would like to have advices or tricks for updating and looking up session objects (JavaBeans and not EJB). Imagine I have the following business objects model: Class A composed of several instances B, each B item can be composed of several C instances. (nested beans). If the list of each sub-beans is variable, must I use dynaBean ? Imagine the user make a request about the instance B2, I get data information and store the JavaBean B2 in the HttpSession. Later the user makes an other request and the B4 instance is required, I store B4 in the HttpSession. Then two problems: 1. The last request needs to get A instance, I get A1 but before saving A1 I have to test if A1 is composed of B4 or/and B2 in order to remove objects from the HttpSession. Then I store A1 in the HttpSession. It is very complicated, isn't it? What are the others solutions to store and look up nested beans ? 2. The WebServer receives a data change notification, in this case how can I look up all active sessions and all session objects of each session to update the JavaBeans which changed? How must I do to be sure that Actions or JSP pages don't access data during update?

One pertinent post is: http://www.mail-archive.com/struts-user@jakarta.apache.org/msg34592.html In short, the answer to what should go in the session depends on how your application will be used. If you expect a *very* high number of concurrent users your session should be under 4k (taken from iAS, WebLogic and WebSphere docs, white papers etc). It will also depend on your hardware, how much RAM is available, network bandwidth, database size/speed etc. If you can predict the highest level of concurrent users, multiple your maximum session size by this. The result will be the amount of RAM taken up by all the sessions put together, if you have sufficient RAM to handle this and all over requirements, then the session size is not an issue. Note however that the number of users can explode unexpectedly, so the best practice recommendation is to keep session size as small as possible. As for the speed of looking up objects from the session, this will depend on your app server, when clustering some app servers will store the session in a db or other persistent store, lookups in this case are relatively expensive. If you are not clustering, I wouldn't worry about the speed of the lookup (even if you are I wouldn't worry about it that much - its not a bottle neck I've ever come across.)

tricky issue - non serializable DiskFile
Hi All, we are working in a persisted environment as is Websphere 3.5. When we use DiskFile it throws the same exception that was reported in this thread: http://www.mail-archive.com/struts-user@jakarta.apache.org/msg25463.html a NonSerializedException for the DiskFile object. It seems to us, that as DiskFile o FormFile belongs to ActionForm, when we declared the ActionForm in the properties with default scope, i.e. session, when WAS attempts to serialize the DiskFile but it is not able to do it since it does not implement Serializable. On the other hand, when we declare the ActionForm to be in request scope, the exception is not raised. This confirms the previous. Therefore, it looks like, that at least in Struts 1.0.2 ActionForms with DikFile attributes can not have session scope. Is this a bug? Could be solved by assigning it transient modifier? Will I need to assign session scope for ActionForms to upload operations?

Re: Struts + MVC Philosophical question
Yes, as a practical matter I would agree the two greatest advantages of a layered approach are error-handling and unit testing. In a JSP, by the time the code realizes there is an error, it's usually too late do much about it. Even more importantly, in a JSP, it can very hard to test the business logic using standard tools like jUnit. So problems are harder to detect and repair. By insulating the View from the Model, it becomes easy to runs demos, unit tests, and other simulations against the View by having the Controller provide whatever data is needed. I'm very much of the opinion that the View should just write what it is given without caring where it comes from. All the View needs to know is the context, the bean name, and the property name, and then it should just do like its told =:0) Of course, if the *bean* has a direct connection to the Model, then you *could be* tapping directly into the Model. But the point is that View has a contract with the Controller (and only the Controller) to expect a bean with a given protocol (in this context, under this name, with this property). If the Controller wants to pass it a bean that is connected to some Model, that's the Controller's business. If the Controller wants to pass it a bean that generates dummy data, that's up to the Controller too. If the Model changes its API, then the Controller has the option of using wrapper rather than changing its contract with the View. So that's up to the Controller too. So the thing to think about is not where the bean comes from, but who's *sending it* there and taking responsibility for the API contract. So long as there is a Struts action in there deciding what bean goes into what context, then the layers are being observed, and all is right with the universe. =:0) -T.

Using a Layered arcitechture, it is incorrect for non-adjacent layers to develop direct dependencies. The View should talk to the Controller and the Controller should talk to the Model. The original M/V/C framework, Smalltalk, made good use of the Observer pattern to streamline processing. The View could register a listener with the Model and be apprised of any change. Though, that is not something many people would do today, since it violates the Layers pattern that evolved from MVC. If the whole shooting match evolved in today's environment, I believe the Observer pattern would have been applied differently, and the View would register with the Controller, which would then monitor the Model on the View's behalf. So, you're right, the original MVC pattern does not prevent the View from chatting with the Model and updating itself. The stricter Layers pattern that Web applications use on top of MVC does. But typing Layered/Model 2/MVC takes too long, and developers are lazy that way :o) So hereabout MVC does mean Smalltalk/Go4 MVC, it means Layered/Model 2/MVC. There's talk about christening that Web MVC or MVC2, but there's not a solid reference for that yet. Ade Barkah wrote: To nitpick... In a strictly philosophical terms, in MVC, the View *may* (and should!) directly access the Model, and on startup one *may* go straight to a View without passing through a Controller. Also, the Model *may* populate its own data without the help of a Controller. Of course when applying MVC to web applications, it's best if all user requests go through a control layer, but MVC per se does not mandate it. This practice is often referred to as the Front Controller pattern.

RE: Iterate with multicolumn data...
Hey, A few people have been wondering about this lately. I was wondering the same thing not too long ago. I just sent this to someone else recently: I just remembered those table resources that I was talking about. It's the display:* tag library. I haven't used it, so I'm not sure exactly how it works, but I read the description and it seems like it allows the creation of tables column by column. I'm not sure though, since I haven't read past the surface description or used it at all. It's available at http://edhill.its.uiowa.edu/display/. Has anyone else used this? What did you think of it?

RE: Display Tag Library
I'm doing the same exact thing right now. It took some doing to figure out how to make it work. But anyway, I have an EntryHolder class in the session that stores a few ArrayLists of entries. It also stores a String[] of the entry numbers to delete. The following code gets the selected index numbers and stores them in that deletion array. When the form is submitted, the user is taken to a confirmation page. When the user clicks the confirmation link, the action calls a method on the EntryHolder class that simply tells it to delete the selected entries, which is simple to do. The code in my JSP includes the following: html:form action=/EditEntry.do?action=confirmtype=md table border=0 tbody align=left logic:iterate id=md name=entries property=mdEntries type=com.moog.us.eos.beans.MDentry indexId=index tr td html:checkbox name=entries property=selections value=%=index.toString()%/ /td td bean:write name=md property=label/ /td /tr /logic:iterate /tbody /table html:submit value=Delete Selected Entries/ /html:form My solution may be somewhat unconventional, but I think it works great. I'm not sure how applicable this design is to what you're doing, but it sounds like you're trying to do the same thing. However, if you're using the Display Tag Lib and displaying info column by column, you'll just have to make some changes in the JSP. Should be pretty simple though.

Form Bean ClassNotFound exception in JBuilder6
Greetings Oh Wise ones. I'm trying to set-up a completely new development using JSP, Struts (v1.02) JBuilder6. I've managed to build a Struts JSP page OK (Struts form actually) and configure web.xml struts-config.xml correctly (the page displayed OK until I attempted to add the Form Bean). I've created a new Form Bean and associated it with the Action class. All the classes compile OK. The problem is, that when I attempt to run the project using JBuilder's internal version of Tomcat (v4.0) I get the following Java exception when I attempt to open my simple page (i.e. http://localhost:8480/Expresso/ResultArchiveAdmin.jsp) :- javax.servlet.ServletException: Exception creating bean of class com.anritsu.eu.Expresso.ResultArchiveAdminFormBean: java.lang.ClassNotFoundException: com.anritsu.eu.Expresso.ResultArchiveAdminFormBean at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImp l.java:457) at org.apache.jsp.ResultArchiveAdmin$jsp._jspService(ResultArchiveAdmin$jsp.jav a:565) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.jasper.servlet.JspServlet$JspServletWrapper.service(JspServlet.ja va:202) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:382) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:474) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Application FilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterCh ain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.ja va:243) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 66) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.ja va:201) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 66) at org.apache.catalina.valves.CertificatesValve.invoke(CertificatesValve.java:2 46) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 64) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2344) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:164 ) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 66) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve. java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 64) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:170 ) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 64) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java :163) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:5 66) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.connector.http.HttpProcessor.process(HttpProcessor.java: 1011) at org.apache.catalina.connector.http.HttpProcessor.run(HttpProcessor.java:1106 ) at java.lang.Thread.run(Thread.java:536) Obviously I'm not telling something (Tomcat, Jasper??) where it can find this Class file.

html:cancel/
From everything that I can tell when using the html:cancel/ tag, my perform() method in my Action class never seems to get executed. It appears that after pressing the cancel button that the forward tag named as cancel in my action mapping in the struts-config file is used and forwards to the specified path, bypassing calling the perform() method. I understand that the validate() method in my form bean won't be called if the cancel button is pressed but I would think that my perform() in my Action class should be called.

Subject: where is ApplicationResources.properties defined? From: David Chu [EMAIL PROTECTED] === I am very confused on how to define a new path for the file currently named ApplicationResources.properties I did not see any definition in either web.xml nor struts-confug.xml. Specifically, is there any way to define it to live outside of the WEB-INF/classes directory? (this is because a clean operation deletes my whole classes directory, including the ApplicationResources.properties file!) Thanks very much for the help. Struts uses the web application class loader to load the application resources file for your application. Therefore, it must either be in /WEB-INF/classes, or inside a JAR file in /WEB-INF/lib. In Struts 1.0, you configure the class name of the application resources by using the application servlet initialization parameter on the controller servlet. In Struts 1.1, you configure this with a message-resources element in struts-config.xml instead. In the Struts example application, the application resources are initialized to org.apache.struts.webapp.example.ApplicationResources, which means that they must either exist as files named /WEB-INF/classes/org/apache/struts/webapp/example/ApplicationResources.p roperties or be in a JAR file in /WEB-INF/lib with the pathname org/apache/struts/webapp/example/ApplicationResources.properties My developemnet setup is similar to yours, in that a clean operation deletes the entire web application output directory. I solve this by keeping the properties files for the application resources in the same directory as the Java source code for the corresponding package (in this case, the package is org.apache.struts.webapp.example). Then, in my Ant build script, I copy all the non-Java source files after compiling, like this: !-- Copy JSP files, WEB-INF configuration files, etc. -- target name=prepare mkdir dir=target copy todir=target fileset dir=web/ /copy /target target name=compile depends=prepare !-- Compile Java classes, output .class files to /WEB-INF/classes -- javac srcdir=src destdir=target/WEB-INF/classes ... /javac !-- Copy everything except sources -- !-- This picks up the application resources properties files -- copy todir=target/WEB-INF/classes fileset dir=src exclude name=**/*.java/ /fileset /copy /target In my CVS repository, all the Java sources and properties files are under src, and all the JSP pages and WEB-INF stuff is under web. Thus, I can reassemble the entire webapp under the target directory any time I want to. If you're not using Ant, you should be able to set up something equivalent to this with your preferred build tools. -- -david Craig -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Plus, as a user you have direct access to the bug tracking system (bugzilla, in this case at http://nagoya.apache.org/bugzilla/ ). There are currently 90 open bugs for Struts. How do I know this? I just looked - it's on-line for everyone to see. If you find a bug, you can add one yourself and someone with appropriate rights in bugzilla will have to address it before it dissapears - it's an extremely 'open book' approach that no vendor would dream of giving you. I've worked for software companies and we would NEVER have opened our bug lists - our competitors would have printed them out and used them against us in sales calls. Eric Raymond, in his essay The Cathedral and the Bazaar says that ``Given enough eyeballs, all bugs are shallow.'' And, at least, that they turn shallow pretty quickly when exposed to a thousand eager co-developers pounding on every single new release. This is why Linux is more stable than NT and Apache dominates the web server market - it's not because it's free, it's because it's BETTER and FREER of BUGS. If I were your boss, I'd worry more about the quality of commercial software than I would about open source. If your manager is concerned about using Open Source becuase of software quality, then get them a copy of Eric's book: The Cathedral and the Bazaar - it's a very short and easy read.

I have almost the same thing in my struts-config. The only difference is that I put the property file in my source directory, and the message-resources parameter refers to the package name.

Subject: where is ApplicationResources.properties defined? From: David Chu [EMAIL PROTECTED] === I am very confused on how to define a new path for the file currently named ApplicationResources.properties I did not see any definition in either web.xml nor struts-confug.xml. Specifically, is there any way to define it to live outside of the WEB-INF/classes directory? (this is because a clean operation deletes my whole classes directory, including the ApplicationResources.properties file!) Thanks very much for the help. Struts uses the web application class loader to load the application resources file for your application. Therefore, it must either be in /WEB-INF/classes, or inside a JAR file in /WEB-INF/lib. In Struts 1.0, you configure the class name of the application resources by using the application servlet initialization parameter on the controller servlet. In Struts 1.1, you configure this with a message-resources element in struts-config.xml instead. In the Struts example application, the application resources are initialized to org.apache.struts.webapp.example.ApplicationResources, which means that they must either exist as files named /WEB-INF/classes/org/apache/struts/webapp/example/ApplicationResources.p roperties or be in a JAR file in /WEB-INF/lib with the pathname org/apache/struts/webapp/example/ApplicationResources.properties My developemnet setup is similar to yours, in that a clean operation deletes the entire web application output directory. I solve this by keeping the properties files for the application resources in the same directory as the Java source code for the corresponding package (in this case, the package is org.apache.struts.webapp.example). Then, in my Ant build script, I copy all the non-Java source files after compiling, like this: !-- Copy JSP files, WEB-INF configuration files, etc. -- target name=prepare mkdir dir=target copy todir=target fileset dir=web/ /copy /target target name=compile depends=prepare !-- Compile Java classes, output .class files to /WEB-INF/classes -- javac srcdir=src destdir=target/WEB-INF/classes ... /javac !-- Copy everything except sources -- !-- This picks up the application resources properties files -- copy todir=target/WEB-INF/classes fileset dir=src exclude name=**/*.java/ /fileset /copy /target In my CVS repository, all the Java sources and properties files are under src, and all the JSP pages and WEB-INF stuff is under web. Thus, I can reassemble the entire webapp under the target directory any time I want to. If you're not using Ant, you should be able to set up something equivalent to this with your preferred build tools. -- -david Craig -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
FW: Really dynamic forms (regex)
I have not been able to find a way to provide this functionality. Olivier is more concerned with how to declare the fields that will be returned as opposed to how to present them on the form. You have to declare the fields in the struts-config file to work with the DynaActionForm. You could of course do it the old fashioned way and just pull it out of the request but I assume you're using the new validator and want to take advantage of enforcing types. From posts I've seen in the past, there is no way out of the box to do this. It would be cool if you could declare your parameter names using regular expressions so you could say something like form-property name=PassengerFName\d+ type=java.lang.String/ form-property name=PassengerLName\d+ type=java.lang.String/ form-property name=PassengerMName\d+ type=java.lang.String/ So that you could have numbered parameters with the same root name and validation could be done across all entries.

Contrary to DynaActionForm which are rather declarative forms than dynamic forms, I have a need for building forms that are parametric. For instance, the Internet user specifies the number of elements he requires, and the system builds dynamically a JSP form containing as many fields as the given number. For instance, for a trip, he gives the number of passengers (let's say 3) and the next form he sees contains 3 fields named for instance passengerName1, passengerName2 and passengerName3. Since I don't know how many fields there will be, how can I design an ActionForm handling this ? If I were to use a DynaActionForm, I would nonetheless be compelled to specify the fields in the struts-config.xml file. Hope this makes sense. Thanks for your help.

One pertinent post is: http://www.mail-archive.com/struts-user@jakarta.apache.org/msg34592.html In short, the answer to what should go in the session depends on how your application will be used. If you expect a *very* high number of concurrent users your session should be under 4k (taken from iAS, WebLogic and WebSphere docs, white papers etc). It will also depend on your hardware, how much RAM is available, network bandwidth, database size/speed etc. If you can predict the highest level of concurrent users, multiple your maximum session size by this. The result will be the amount of RAM taken up by all the sessions put together, if you have sufficient RAM to handle this and all over requirements, then the session size is not an issue. Note however that the number of users can explode unexpectedly, so the best practice recommendation is to keep session size as small as possible. As for the speed of looking up objects from the session, this will depend on your app server, when clustering some app servers will store the session in a db or other persistent store, lookups in this case are relatively expensive. If you are not clustering, I wouldn't worry about the speed of the lookup (even if you are I wouldn't worry about it that much - its not a bottle neck I've ever come across.)

I read that the Struts framework doesn't make (oblige) to use one particular model implementation (EJB, JavaDataObject, JavaBean, ...). But the JavaBean solution is understood or greatly recommended, isn't it ? Because struts uses JSP to display data and JSP pages use JavaBean tags. If we work whit XML representations of remote business objects, is it better to use struts XSL tags rather than generate JavaBean from the XML description ? The XSL solution requires to know XSL tags and is slower and more complex. With JavaBean solution I am frightened having memory or request time problem. The user does a request, the selected Action gets business data from the enterprise tier, generates one or several JavaBean instances and stores the JavaBean in the HttpSession. But the HttpSession size will grow quickly. It is difficult to know when we have to store data in request scope or session scope. Has somebody advices about this dilemma? I am tending to put data systematically in HttpSession in order to reduce network traffic if the user ask again this page. What is the max size of the session objects ? If we user rights on the business objects, we will have the same JavaBean in several HttpSessions. What do you think about this problem ? A last question if we have numerous session objects, when we will have to update one of them it will be very slow to find it in the list. Do you have advices about that ? Is the JavaBean/HttpSession solution realistic with real-time data?

RE: where can caching help performance
And to continue my obviously inadequate and lame answer ... Disclaimer: I didn't write the code, I just asked that it be written like this (i.e. I drove the logical design) ... these are the perils of being a tech lead on a project and having to trust that the developers really did what you asked and really implemented it the way that they explained it to you. The behaviour of the system is exactly how I asked for it to be, so I'm happy, but I haven't had much opportunity to peek under the covers yet. The app never touches the cache. It makes requests to the DB subsystem and that makes a request to the cache manager and then receives a business object. The app never knows if the object was their in the cache at request time or if it had to be dynamically fetched. All it knows is that it asked and it received (kinda biblical :-) The cache manager is the only part of the system that knows what it's doing as far as creating, updating and purging cached business objects.

Re: html:cancel/
It turns out that on our project they are overriding several methods in the ActionServlet one of which changes the way the cancel button is handled. On Fri, 12 Jul 2002, Paul McKinney wrote: From everything that I can tell when using the html:cancel/ tag, my perform() method in my Action class never seems to get executed. It appears that after pressing the cancel button that the forward tag named as cancel in my action mapping in the struts-config file is used and forwards to the specified path, bypassing calling the perform() method. I understand that the validate() method in my form bean won't be called if the cancel button is pressed but I would think that my perform() in my Action class should be called.

Re: ActionServlet question
I think a small example test case would be really helpful, as I'm having a hard time understanding what the issue is. For me, and for basically every other Struts user, the controller is invoked once per HTTP request that has a URL pattern mapped to the controller (i.e. things that end in *.do in the struts-example app), so I don't understand what you mean by the controller only gets executed once.

I think we are getting confused over terminology. The action servlet is configured in web.xml, not struts-config.xml action elements. You are write! I am actually not talking about the ActionServlet but about the Class Action that is a Servlet as well ;) Sorry for not beeing clear! I think I understood the MVC concept. Maybe it is more easy to make me understandable when I tell what I want to do: I have a form that is using Struts. So all the validation and stuff works just fine. After all required values where put in correctly the values of the form are beeing copied into a model bean. (just like in the struts-example !) Next step is to forward to a .jsp page (as configured in the same action forward name=mypreview path/preview.jsp/)that gives a preview of inserted data. The data comes out of the model bean. The user has now two options: Save or Edit (Save makes the persistance). When clicken Edit the user is beeing sent back to the input form. I thougt all this is one action! And I need only one Controler Servlet (Action Class) for that. The options (Save or Edit) I wanted to give via the Querystring to the Controler Servlet (/app/myinputform?action=save or /app/myinputform?action=edit). Then the Controler Servlet would deside if the data should be written to the DB or the from should be shown with the preveously inserted values. Well, I found out that the code of the Controler Servelt is only executet once. And that is after I correctly filled out my form! When I agan call the action path=/myinputform via the belonging path there is only the empty form an the Controler Servlet was not proccessed. could I make my selve more clear??? If not I sort of write a documentation of my little test app. Craig thnks a lot for your help in advanc. I guess I am having a still a problem in understanding how Struts works.

The DTD file is also in the same directory of the xml file and specified in the xml file as !DOCTYPE Certificate SYSTEM BRSUCofA.dtd. Using this relative URL as the system identifier requires the DTD to be in the same directory that you put the XML file. Could anyone tell me the best way to handle this problem? One way I think about is to upload the DTD file and save it somewhere in the application directory. This directory should be specified in ApplicationResources.PROPERTIES file. Then upload the xml file and parse it with the saved DTD file. Could anyone tell me how to set the directory to the parser so that the parser will know where to look for the DTD file? I also need to know how to save the DTD files in struts to a given path. If the DTDs for your uploaded files are reasonably static, you might consider just putting them on a webserver somewhere and using an http system URL like the Struts DTDs do. For better performance, you can also configure Digester to use a copy of the DTD inside your webapp instead of going to the external web server every time -- for an example of this, take a look at how ActionServlet sets up its Digester to parse struts-config.xml files, and uses the register method to register internal copies for some specified public identifiers.

[EMAIL PROTECTED] skrev:
...anyone remember DynaMen?
Anyhow... I got a Dynabean mechanism working that builds a DynaBean
based on the metadata of a SQL result set, populates and array of the
little buggers and passes it back to me. For displaying I have a tag
library that does not like a call to get('name') as the field name.
What is the best way to get around this?
I wrote an AnonyBeans package which uses BCEL to generate beans on the
fly based on a ResultSet. It is alpha code but works for me, and is
usable anywhere where you need a real traditional bean, but where you do
not want to serialize it or use its type in Java source.
Is this interesting?
I think it would be interestesting, even though it might not be
universally useful (some containers won't let you introduce new classes at
runtime).
I'd also be interested in a mechanism that converted a ResultSet into a
custom DynaClass, with a corresponding DynaBean for each row. This would
be trivially simple to do -- so simple that it probably makes a worthwhile
addition to commons-beanutils itself if someone wanted to take this on.
This wouldn't help you create dynamic input forms, but it would make a
completely flexible bean-like wrapper around a result set so you can use
Struts tags to display stuff.

Re: Should I bother to try and handle this with struts?
Please note that I have not used the items I am about to tell you about :-) That having been said: DynaForms - from what I understand, they will suck up anything and poke it in a hash. I'm not sure whether you could use this - or maybe DynaBeans - but, from my (limited) understanding of them, I think you probably could. Internally, as I said, they poke things into a hash. Now ... hrm ... I need to catch up on the new Struts features :-) I really think you can acheive this. To get someone elses attention, post a new topic about Help with DynaBeans/DynaForms.

Eddie, thanks for your info on container management but actually my question really isn't about how to manage authentication. (I should have been more clear). It is how do you use Struts to generate form field names that will be generated dynamically and then later have access to them to using an Action Form or a configured Dynamic Action Form. Let's change the whole scenario around and say I'm creating a page that has a list of items and you have to select the favorite color of each. For example: car[ select options of colors to choose ] house [ select options of colors to choose ] sofa [ select options of colors to choose ] Now the problem is that the items are generated dynamically so that the application doesn't know until run time what these items will be. Is there a way to have a Struts Action Form manage gather this kind of information. I was hoping to avoid when the above form would submit having to do this in some business object using the request object: //get List from db //loop through list and during each iteration: String colorValue = request.getParameter( itemInList ); //now update db with this value for this item //continue loop Maybe I have no choice. I'm just not clear how I can use a Struts form to capture this dynamic list of items, since I can't configure the fields beforehand.

...anyone remember DynaMen?
Anyhow... I got a Dynabean mechanism working that builds a DynaBean
based on the metadata of a SQL result set, populates and array of the
little buggers and passes it back to me. For displaying I have a tag
library that does not like a call to get('name') as the field name.
What is the best way to get around this?
I wrote an AnonyBeans package which uses BCEL to generate beans on the
fly based on a ResultSet. It is alpha code but works for me, and is
usable anywhere where you need a real traditional bean, but where you
do
not want to serialize it or use its type in Java source.
Is this interesting?
I think it would be interestesting, even though it might not be
universally useful (some containers won't let you introduce new classes
at
runtime).
I'd also be interested in a mechanism that converted a ResultSet into a
custom DynaClass, with a corresponding DynaBean for each row. This
would
be trivially simple to do -- so simple that it probably makes a
worthwhile
addition to commons-beanutils itself if someone wanted to take this on.
This wouldn't help you create dynamic input forms, but it would make a
completely flexible bean-like wrapper around a result set so you can use
Struts tags to display stuff.

BeanUtils.describe and BeanUtils.populate indexeed properties...
I saw a similar issue on the archive but did not see what the solution to
this was, so decided to ask the same question again.
Do BeanUtils.describe and BeanUtils.populate supposed to handle indexed
properties?
Suppose I have this JavaBean:
public class NameBean {
private String[] name;
public String[] getName() {
return this.name;
}
public void setName(String[] name) {
this.name = name;
}
public String getName(int index) {
return this.name[index];
}
public void setName(int index, String name) {
this.name[index] = name;
}
}
NameBean nameBean = new NameBean();
nameBean.setName(new String[] {John, Paul, Jack});
Map properties = BeanUtils.describe(nameBean);
I would expect the following code to return a Map containing:
name[0]=John, name[1]=Paul, name[2]=Jack
but instead,
I get name=John.
Only the first element is considered.

Craig wrote: The validator framework already lets you write reusable custom validation functions, and it already supports dynabeans -- what do you need that is not already available? I'm a big fan of keeping as much stuff in one place as possible. By using the form-property tag, you can almost entirely do away with the need to write the form bean, but you still need to specifiy validations. In almost all cases, fields in forms are independently validated. If there was a way to specify a validation out of the validator framework in the form-property, that would be almost as useful to me, except that I consider Validator to be a 900 lb gorilla and wish I wasn't obliged out of hand to use it. This kind of leads into a parable of Jakarta I've been thinking of: A man was building a house, and needed to measure a piece of wood. He had a tape measure beside him, but he thought My friend Joe has just developed this cool laser-based measuring device that will give me a result with 10 times the accuracy. It sometimes returns totally wrong results, because it's still being developed, but it's dead-on the rest of the time. So, he looked around for a way to get to his friend Joe's house. He had a car sitting right there, but he knew his friend Chuck had a new rocket-powered airship that would get him there in 1/10th the time. Of course, the airship took 2 days to configure for launch and occasionally blew up. Now how to call Chuck and ask to use the airship? He could call on his cellphone, but there was this new implantable communications device he was dying to try out... The point?

I'll turn your question around, Craig. If I want to use DynaBeans but don't want to use the Validator framework (which at first glance is going to take me half a day to configure properly), why should I be forced to.

Hi Sven,
I guess the easiest way would be to add an action property to your form
then
add a html:hidden property=action value=search/edit/ to your jsps.
Then in your validate method check the value of the action property and
validate accordingly.

I did it that way, too and it worked.

I'm wondering about this problem because it's so fundamental.

I do it as specified in my previous post. Although I'd use the same action
form to store search and editing values, this way the mapping.getName ()
bit
in the search action would work (no hard coding of the key to use to store
the search results in session/request for editing).

If you don't want to use it, you don't have to -- but don't expect *me* to lift a finger to help you write your own :-). The one we've got works just fine, thank you. (And, the validator framework isn't specific to Struts, either -- you can use it in your model tier as well as the presentation tier if you need it.) If, instead, you'd like to contribute a way to configure the validator framework by add-ons to struts-config.xml so that you really can do it all in one file, patches are welcome. By the way, Chuck's downloadable chapter on the Validator Framework (at www.theserverside.com) covers pretty much everything you want to know about how to set this all up.

Help: Passing object through http from one jvm to another
I am trying to pass a java object from my perform method to a servlet running in
different JVM .
My perform method returns Actionforward object redirecting to the same servlet. Here
is what I have tried:
Perform method:
Object resultObj = getObj();
URL url= new URL(http://localhost:8080/CallbackServlet;);
URLConnection uConn = url.openConnection();
uConn.setDoOutput(true);
uConn.setAllowUserInteraction(false);
uConn.setUseCaches(false);
uConn.setDefaultUseCaches(false);
ObjectOutputStream outputToHost = new ObjectOutputStream(uConn.getOutputStream());
outputToHost.writeObject(resultObj);
outputToHost.flush();
outputToHost.close();
String callbackClassName = (String) session.getAttribute(Constants.CALLBACK_CLASS);
String callbackClassInvokerURL =
http://localhost:8080/CallbackServlet?callbackClassName=+callbackClassName;
if(callbackClassInvokerURL != null) {
TxActionForward af = new TxActionForward( callbackClassInvokerURL );
af.setRedirect(true);
return af;
}
and the CallbackServlet: Service method
ServletInputStream si = request.getInputStream();
// get object to be viewed
ObjectInputStream inputFromClient = new ObjectInputStream((InputStream)si);
Object resultObj = null;
resultObj = (Object)inputFromClient.readObject();
inputFromClient.close();
This did not work. It never comes out of the following statement
// get object to be viewed ObjectInputStream inputFromClient = new
ObjectInputStream((InputStream)si);
Could anyone explain what's wrong in the above program? or please suggest some other
route?
Thanks

child window problem!!!!!!
Hi guys, We are using Struts in our project and have a kind of road block stopping us to proceed. Problem is described below and any help on this will be appreciated. We have an Assign.jsp with AssignForm and AssignAction. From Assign.jsp user may perform actions like assign a person, Search a person, See details of a person and Change a person. We are using Dispatch action as a superclass for our AssignAction form and we pass appropriate actiontype as parameter when an action takes place. We are kind of stuck at search person. Requirement is when a user keys in partial name and presses search link(this is html:link) a new window should open up with name of all the people with the matching name with the partial name typed in by the user. We have our search form ready and in the action of this search form we are using a business delegate to get us a list of people. Our problems are 1. How can we open a new window from Assign.jsp and open Search window? 2. Search window needs search values from the parent window (Assign.jsp). How can we pass this to Search.jsp and invoke SearchAction to perform the search on the parameter passed and display the results to the user in search.jsp? 3. When user makes his selection in the Search.jsp we wish to close the Search window on selection and refresh the parent window(Assign.jsp) with the value selected by the user in Search.jsp. How can we do this? Thanks, Samip. __ Do You Yahoo!? Sign up for SBC Yahoo!

newbie question: html:select .... size=
Hi
I'm new to struts ( and java beans for that matter )
I'm trying to dynamically re-size a select box i'm
creating on my page
in java i have a function
public String getSelectSize()
{
return 10;
}
on my jsp page i have something like
html:select multiple=true property=itemsSelected
size=bean:write name='MyForm' property='SelectSize'
/
my problem is the bean:write is not evaluated in this
case
if i remove the quotes or try % % i get compile
errors
is there a simple way to do this?
thanks

Action object doesn't get attributes...
Here is a question from a collegue of mine (see below). Basically last year when they started using Struts on one of their web applications they could use request.getAttributes from their Action object and everything worked fine. However, now it seems that they need to use an ActionForm object which isn't possible in this case since the form objects to be submitted change based on the user logged in. Anyone have an answer? I just saw a mail from Craig explaining that form parameter values are treated differently now than they were before, however he says they are using the same version of struts (1.0) as they did before. Thanks, /tataryn:craig Original message: For those of you who I asked already, I did some more testing and included some more information: Have any of you come accross the following? It seems that the form attributes are not available to the struts Action object unless they are put into an ActionForm. If they are not put into an ActionForm (or if there is no ActionForm defined for the page) then the data is unavailable to that Action object. This did not happen in last years application (both are using the same struts version). Is there some configuration setting that might be causing this? Is the presence of ANY ActionForm that is defined on that page mess up forms for which there is no ActionForm? Thanks for any info you might have on this. Craig W.

I've posted a solution at: http://www.swanked.net/dds/popup/ I can send you the code for it if you want -Original Message- From: Samip Ladhawala [mailto:[EMAIL PROTECTED]] Sent: Friday, July 12, 2002 1:51 PM To: [EMAIL PROTECTED] Subject: child window problem!! Hi guys, We are using Struts in our project and have a kind of road block stopping us to proceed. Problem is described below and any help on this will be appreciated. We have an Assign.jsp with AssignForm and AssignAction. From Assign.jsp user may perform actions like assign a person, Search a person, See details of a person and Change a person. We are using Dispatch action as a superclass for our AssignAction form and we pass appropriate actiontype as parameter when an action takes place. We are kind of stuck at search person. Requirement is when a user keys in partial name and presses search link(this is html:link) a new window should open up with name of all the people with the matching name with the partial name typed in by the user. We have our search form ready and in the action of this search form we are using a business delegate to get us a list of people. Our problems are 1. How can we open a new window from Assign.jsp and open Search window? 2. Search window needs search values from the parent window (Assign.jsp). How can we pass this to Search.jsp and invoke SearchAction to perform the search on the parameter passed and display the results to the user in search.jsp? 3. When user makes his selection in the Search.jsp we wish to close the Search window on selection and refresh the parent window(Assign.jsp) with the value selected by the user in Search.jsp. How can we do this? Thanks, Samip. __ Do You Yahoo!? Sign up for SBC Yahoo!

How can we pass this to Search.jsp and invoke SearchAction to perform the search on the parameter passed and display the results to the user in search.jsp? Build them into the URL you pass to window.open(). 3. When user makes his selection in the Search.jsp we wish to close the Search window on selection and refresh the parent window(Assign.jsp) with the value selected by the user in Search.jsp. How can we do this? This depends on how your app is structured. Here are a few options: 1) Use JavaScript in the search page to stuff the selected value back into the parent page and then close the search window. 2) Submit a request from the search page, and save the selection to the session. The response for that request would be a page which uses JavaScript in body onload=... which forces the main page to refresh and then closes the search window. 3) Use a hidden form on the main page. The search page would set the selection in a hidden field in that form, submit that form, and then close the search window. -- Martin Cooper Thanks, Samip. __ Do You Yahoo!? Sign up for SBC Yahoo!
