Re: Is there a default action if the requested action dosen't exist?

If the user types in a wrong/incorrect/bogus file path after a valid struts application, ie http://localhost:8180:/testapp.do/logo.do http://localhost:8180:/testapp.do/asdufho then I want the request to be mapped to http://localhost:8180:/testapp/logon.do How can I do this? In your web.xml file, insert somethink like: error-page error-code404/error-code location/logon.do/location /error-page (Note that the order of elements in web.xml is important; error-page tags should come right after any 'welcom-file-list' tag) Also note that forwarding to the login page will not work if you are using container-manager security (as then you are not allowed to forward to the login page directly), however forwarding to something like '/notFound.do' will work.

Population of Collections in a Form from Request
Hello, Is there a way (implemented in Struts ?) to get the collections in Form Bean automatically populated with User Request, before going to the Action class. The Collection itself has a list of beans. I am using nested tags to display the Collections present in Form bean. They are displayed perfect. But the problem is in getting the input back from the page with the nested beans automatically filled up. I have written a method in my Form bean which returns a beanin the Collection based on the index asked for. Though Controller is able to populate the inner beans, it is not consistent. Only some attributes of the inner bean get populated. Have anyone dealt with this type. help is very much appreciated Thanks Sai -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Mapped property
It appears that you are trying to call a method on an attribute of a
bean. It also appears that the attribute is the instance of a class.
To my knowledge this is not supported. Note, if you are simply trying
to access the attribute of an attribute stored in the bean you can do
this using the dot operator. I don't believe that you can call methods
on the bean via the rtexprvalue of the bean:write call.
If you desire call a method on an attribute of a bean, expose the bean
to the page via the jsp:useBean tag.
= Bean Class ==
package com.mycompany;
public class MyBean {
private Address address;
...
public Address getAddress() {
return address;
}

public class Address {
private String address1;

public String toString() {
StringBuffer tmp = new StringBuffer(address1);

tmp.append(address2);
tmp.append(,);
tmp.append(address3);
tmp.append(,);
return tmp.toString();
}
}

Re: Can I directly access properties in my ApplicationResources file?
The ActionServlet loads the MessageResources via the initApplication()
method. One should really request the MessageResources from the
ActionServlet to eliminate extra I/O calls. In general, Action classes
extend the ActionForm and can access these via the following call:
public class MyAction extends Action {
public ActionForward perform(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException (
MessageResources recources = this.getServlet().getResources();
}
Note, that an Action can gain access to the servlet via the call to the
getServlet() method. See the Action class. Once you have a reference
to the ActionServlet you can get the MessageResources via a call to the
getResources() on the ActionServlet. Though a direct call to
getResourceAsStream() works, it's not as effective since the
ActionServlet has already loaded these values.
Note, the ActionForm also has access to these resource since the
ActionForm has a method getServlet(). One the MessageResources is
loaded in the ActionServlet most classes have access to this via the
ActionServlet.
Hope this helps,
Steve
Mike Olivieri wrote:
A similar approach is using the getResourceAsStream() method from any class.
InputStream propFileStream =
getClass().getResourceAsStream(/com/companyname/appname/app.properties);
Properties props = new Properties();
props.load(propFileStream);
This works well for any kind of application, and will search the classpath
rather than the filesystem for the properties file.
Sometimes, there can be an extreme proliferation of properties files. In a
large app, you'll have potentially hundreds of properties. Make sure that your
properties keys are descriptive enough that you could potentially combine them
into one properties file. You wouldn't want to just use:
driver=oracle.jdbc.drivers.OracleDriver
Instead, use
appname.subsystem.jdbc.driver=oracle.jdbc.drivers.OracleDriver
And finally, Mark is absolutely right about not mixing logic in your tiers.
Make sure that any business logic you have is encapsulated in classes that are
used by the Action class - don't put the business logic directly in the Action
class. It's not really much more typing, and will actually be easier to debug
and support... and reuse!
--- Mark Rines [EMAIL PROTECTED] wrote:
Scope, scope, scope. Once you're in your Action class, you are in the
business logic scope of your application. Your business logic should have
nothing to do with Struts, or any other non business related architectural
implementation ( such as Swing, JAAS, etc...), architecturally speaking. So,
use the classes and methods used for manipulating any other properties file,
which is just what the ApplicationResources.properties file is, no more, no
less. For more info see the Properties class , and the supporting classes
Property*. Reading can be as easy as:
...
PropertyResourceBundle p = new PropertyResourceBundle( new
FileInputStream(ApplicationResources.properties) );
...
String propertyValue = p.getString(myKeyName);
...
Hope this helps.

Which webcontainer to use? (Linux/Solaris/MacOS)
Hi. We are converting an existing character based database application to a web based ditto, and have now surveyed the marked and found that Struts is a viable solution which I am now trying to get running (had to write some beans to interface to the database first - this was _not_ what the database schema was designed for), and we are not interested in going EJB, since we may want to create a stand-alone application later. I have done my initial testing on a Tomcat 4.0.1, but have found that it has some problems with calling CGI programs, and I therefore wonder whether I should move to the latest Tomcat 3.x instead? Would I loose some functionality regarding web applications which would outweigh any advantages in going to a more tested version of Tomcat? Should we consider another web container all together? Resin has been strongly recommended. Cross platform usability is a definitive must, since we develop under Linux and Mac OS, and deploy under Solaris, and I would really like the option of being able to tweak the source. We are not far enough that we are willing to pay for a commercial solution, but this is - in the future - an option if the benefits are sufficiently large. This is software for running at a hospital. Currently I work with Forte and Emacs depending on what I need to do. Any suggestions for the web container, and perhaps some auxillary software? -- Thorbjørn Ravn Andersen Scandiatransplant, c/o Christian Mondrup 89 49 53 01 http://biobase.dk/~tra -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Mapped property
I think this is not the problem.
I retrieve from a database multilanguage data for my beans. So if my locale
language is set to en I would like to call a method in my beans like this:
public String getProperty(String language);
But within the jsp page there is no way to call it with a mapped property in
a dynamic way. This a way to do it:
logic:equal name=the key for the locale property=language value=en
bean:write name=element property=property(en).property /
/logic:equal
logic:equal name=the key for the locale property=language value=it
bean:write name=element property=property(it).property /
/logic:equal
The problem is if I would like to add a new language I have to modify all my
jsp pages.
I tried to find if there is another way to do it.
For example I put in the application scope a bean wich is a Collection of
String of language information.
This way I can write:
logic:iterate name=languages.bean id=lang
logic:equal name=the key for the locale property=language
value=???
bean:write name=element property=property(it).property /
/logic:equal
/logic:iterate
The problem is I can't compare the values returned from 2 beans.

I looked at the Ultimate Browser Sniffer (http://www.mozilla.org/docs/web-developer/sniffer/browser_type.html) and thought it would be useful to have a server side version, call it BrowserSniffer which provides an API similar to the Ultimate Browser Sniffer (isIEUp(), isNav(), etc...). The filter would first check to see if BrowserSniffer was in the current user session. If not, it would create a BrowserSniffer with the user-agent request header and place it in the session. A custom tag or a set of tags (or scriplets; blasphemy! :) ) could be used to extract information from BrowserSniffer to determine the appropriate presentation logic. I'm assuming there would be an advantage to this because the parsing of the user-agent field would occur once per user session unlike the Javascript version which needs to parse the user-agent field on each page that is rendered, not to mention that it must be included on every page. So, has anyone attempted this before or does there already exist an open source solution or do people pretty much just stick with the client side solution.

Chapter 1 + 2: hopefully short, as they appear in (almost) every Java-server-related book keep them to what Struts does differently Chapter 8: Is this an introduction into using a taglib (then make it short) or an intro into writing a taglib (does it fit into the O'Reilly focused and small approach?)? Chapter 9: Where is the Struts-related part? That chapter can cover books on its own... Chapter 13: Make it a bit more general: Separating Struts (Presentation) from EJB or plain Javabeans (business logic). Almost the same rules apply to JavaBeans as well as EJB's. Samples could also be EJB only... Chapter 18: Logging is important also for the Business-Logic, so it should be separated from Struts... Chapter 20+21: Important for people learning Struts, so do them well Appendix A: Depending on the format could fill up the book without aiding to much.

Re: Tools for Building Web Services (fwd)
That's cool Stefan, Thanks for the tip. I do know that GLUE does more to speed things up than use a SAX parser.. only part of the speed-up comes from their own non-validating parser EXML (it was non-validating last time I looked)... I compared EXML to Xerces awhile ago.. and it was much faster. However GLUE can do other things to reduce the payload.

RE: Want to check user is logged in every page server]
Hi,
with a servlet 2.3 engine (like Tomcat 4,...) you could write a filter checking
for this and then either let the user proceed (if logged on) or reroute to
a login-page (if not).

Subject: AW: Want to check user is logged in every page server]
Hi
In the struts example the method used( as many people have pointed out)
to check that the person requesting the page is logged on is to have at the
top of each jsp a tag like
custom:checkLogonTag/
This tag should check to see if some sort of bean is present - this bean
indicates the user has logged on successfully - (method 1).
Do I need to do anything else or is this the safest way to ensure a user
is loged on before serving them the requested page.
Question, is there any point of having some sort of database record to
indicate a user has loggon on and checking with that database record as well
as the bean in (method 1) that the user is logged on?
Cheers
Tony
You can do this with a custom tag
custom:checkLogonTag/
of course you also need to implement this tag.
this is what actually does the job:
public int doEndTag() throws JspException {
// Is there a valid user logged on?
boolean valid = false;
HttpSession session = pageContext.getSession();
if ((session != null) (session.getAttribute(name) != null))
valid = true;
// Forward control based on the results
if (valid)
return (EVAL_PAGE);
else {
try {
pageContext.forward(page);
} catch (Exception e) {
throw new JspException(e.toString());
}
return (SKIP_PAGE);
}
}
Take a look at the example Mailserver application that comes with Struts.

We are converting an existing character based database application to a web based ditto, and have now surveyed the marked and found that Struts is a viable solution which I am now trying to get running (had to write some beans to interface to the database first - this was _not_ what the database schema was designed for), and we are not interested in going EJB, since we may want to create a stand-alone application later. I have done my initial testing on a Tomcat 4.0.1, but have found that it has some problems with calling CGI programs, and I therefore wonder whether I should move to the latest Tomcat 3.x instead? Would I loose some functionality regarding web applications which would outweigh any advantages in going to a more tested version of Tomcat? Should we consider another web container all together? Resin has been strongly recommended. Cross platform usability is a definitive must, since we develop under Linux and Mac OS, and deploy under Solaris, and I would really like the option of being able to tweak the source.

Re: handling exceptions
We've developed a pretty eloborate exception handling framework on my current project. We're using EJB on the backend, so we must also deal with remote type exceptions. First we catorgize exceptions into those that the user can recover from and those that they can't. Sort of like fatal and non-fatal. You also need to divide exceptions into system and application exceptions. System exceptions are ones like remote exception, or maybe some type of datastore exception. Application exceptions for us are ones like required fields were missing or duplicate values for a unique column. In our world, the same exception framework has to work for ERP systems, so it's not just the web container. Anyway, for those exceptions that the user can recover from like required fields missing, we catch those type of exceptions, create an ActionError with a message from the bundle specifically for that exception, and then forward back to the input page. This gives the user a chance to fix the problem and resubmit. For the more severe exceptions, we also catch those and forward to a system-error type page since there's probably nothing you can do about it anyway. We use an abstract base action that all of our actions extend. We have all of this behavior in the base action and none of the action classes have to worry about catching these exceptions. The abstract base action implements the perform and has an abstract doWork type method. The doWork method is wrapped with the try catch blocks. Each concreate action class implements the doWork and doesn't have to worry about the try catch. I hope that gives you some ideas. chuck p.s. Regarding your other post about using System.out in your action classes; I wouldn't recommend that approach. Use log4j instead. That way, you can shut off the debug logging externally by just editing the log4j.properties file. At 09:50 AM 1/28/2002 -0200, you wrote: Could somebody help me ?

Anyway, for those exceptions that the user can recover from like required fields missing, we catch those type of exceptions, create an ActionError with a message from the bundle specifically for that exception, and then forward back to the input page. This gives the user a chance to fix the problem and resubmit. For the more severe exceptions, we also catch those and forward to a system-error type page since there's probably nothing you can do about it anyway. We use an abstract base action that all of our actions extend. We have all of this behavior in the base action and none of the action classes have to worry about catching these exceptions. The abstract base action implements the perform and has an abstract doWork type method. The doWork method is wrapped with the try catch blocks. Each concreate action class implements the doWork and doesn't have to worry about the try catch. I hope that gives you some ideas. chuck p.s.

RE: Problems with getting the Oracle thin JDBC drivers loaded with Struts 1.0.1 under Tomcat 3.3a
Tomcat 3.3 and 4.0 follows the strict specifications of servlets : Chapter 9.4 about Web App directory structure in the Servlets 2.23 spec : The contents of the WEB-INF directory are: * /WEB-INF/web.xml deployment descriptor * /WEB-INF/classes/* directory for servlet and utility classes. The classes in this directory are used by the application class loader to load classes from. * /WEB-INF/lib/*.jar area for Java ARchive files which contain servlets, beans, and other utility classes useful to the web application. All such archive files are used by the web application class loader to load classes from. go to http://java.sun.com/products/servlet/download.html and downloads the specs. It's very instructive.

Re: RES: handling exceptions
That's a good idea. The only issue that I can think of is that you'll be dependent on 1.4, since the logging API isn't available to previous SDKs. Something like log4j is available to 1.1 and above. There's no reason that I can think of why anyone wouldn't use the latest version of the SDK, but I'm not sure everyone will switch immediately.

Re: Only one logged in session at a time for each user
You should store their current session ID in some kind of persistent store, like you say. Then I would suggest that if they log in a second time, that you invalidate the *old* session and let them continue with new one. I've seen that approach used on a large public web site.

I was thinking that I can have have some sort of record in (an application wide bean)/(a database record)/(the logon action) that keeps track of who is logged on and when the log on process happens this record is checked, if the user is already logged on then don't let them log on again. The problem I can see with this is that this works fine if the user logs out of the application through a logout action - the logout action can simply clear the record of the user being logged in. But if the users browser crashes, they reboot the machine, they simply restart the browser then this record will not be cleared and thus they will not be able to log in. I cannot think of how I can implement a mechanism to ensure only one log in at a time. The thought of adding some sort of timeout value seems a little nasty, since I hate it when I go to a site and I am told I am alread logged in, please try back in 10 minutes.

RE: OReilly Struts book
I agree with you T. that using an IDE to set breakpoints, step and watch variables is the preferred method for debugging. I have used Struts in Visual Age for Java 4.0 for a while now and I have saved SO MUCH TIME in debugging. I have been able to debug and step right through the Struts source, and errors which would have taken hours to find, have taken me minutes. I just can't stress enough how important an IDE can be for a developer. You can save yourself and the company you work for a lot of time and money by being more productive and getting the work out a lot faster by using these tools. I believe that a chapter in the struts book about debugging with an IDE would be a great way to teach people about how much more productive they can be by using these tools, while at the same time making the book more marketable.

RE: OReilly Struts book
Chuck, Congratulations on the contract. The content looks pretty good. I would highly suggest that you include a chapter on Tiles and the tiles.xml file. I have found tiles to be extremely time saving and allows a more modularized approach to page development. I know people who started to use struts simply because of the tiles integration. I know that it is a pretty in depth subject if you are going to show some best practices with it. I bet you can find plenty of people to give you help.

RE: What happens when our session expires?
There you go! That sounds good. So I'm assuming (bare with me, I haven't done much with session time outs) that you code some type of event procedure which is kicked off when the session times out? You can then do cleanup stuff at this point? How do you get at your form bean? If memory serves (and it's been a while), your form beans are always passed to you as a parameter. Unless you can get at them some how through the session object? Thanks, Craig.

ReQ: Only one logged in session at a time for each user
Hi there, I am too interested on this.The suggestion is good.How can I get session object from the Id.I think one way is through HttpSessionContext class. I found this class has been deprecated. any other way to achieve this Alvin second time, that you invalidate the *old* session and let them continue with new one. I've seen that approach used on a large public web site.

RE: OReilly Struts book
A Struts-specific book will not doubt be welcome by the existing community and attract new developers. Being a new Struts user, I like the off-the-shelf MVC implementation, especially now that validation and authorization can be integrated. It appears that you'll cover these concepts and capabilities. One topic I don't see in your outline that would interest me would be integrating non-JSP presentation technologies. Not everybody thinks JSP is the greatest thing since sliced bread. Ted Husted has recently collaborated with the Jakarta Velocity team on a Velocity integration strategy. I'm working on Enhydra XMLC (but haven't seen the need to go to a completely separate servlet -- yet). Others are looking at an XML/XSL-based solution. What is lost from Struts by not using JSP? How are certain concepts -- say transaction tokens -- still useful but require somewhat more work? I'm looking forward to seeing it on the bookshelf.

Re: Only one logged in session at a time for each user
I have used a combination of ip_address and jsessionid which I store in an active_session table. Every action they do I check the table - if the ip address changes (ie someone has nicked the session id) then I ditch the record and make em log in again. If the same user logs in again from same IP address I let them right in, no logon required (within a time period). If the same user logs in from another ip address then I bouce the first one off... It stops users using each others passwords as a rule - it's too annoying. The problem is proxies and gateways which mask off original ip addresses. Can't have everything.

Hi there, you probably have heard this question a million times before, but I couldn't really find anything in the archive which answered it. So here it goes: We have an application for which we would like to use struts. This aplication allows users to enter performance evaluation information on employees in the firm. I would like to know this: The user starts a performance evaluation, and half way through decides to go grab a bite to eat, comes back and finshes the evaluation, when he/she hits the save evaluation button their session is going to be kaput. Let's assume that the evaluation is a wizard type application and relied heavily on an ActionForm class to store the information entered on each page. How do you overcome this problem? Make sure to store all their previously entered performance evaluation data in a hidden field on the client side? Any help would be greatly appreciated. /tataryn:craig Craig W.

RE: RES: handling exceptions
Well, since Tomcat (for instance) runs the JVM you install then you get the logging and exception stuff as soon as you install 1.4, You do NOT get it within the tomcat code, but you do within your own code. i.e. if their stuff fails then you won't see it. But if your stuff fails, or logs then you get it as soon as you use JDK1.4 (I have yet to use it in anger, I must admit - probably for the reason you just stated :) Jonathan Want to write your code as if you used EJB, but you don't?

We're using EJB on the backend, so we must also deal with remote type exceptions. First we catorgize exceptions into those that the user can recover from and those that they can't.

System exceptions are ones like remote exception, or maybe some type of datastore exception. Application exceptions for us are ones like required fields were missing or duplicate values for a unique column. In our world, the same exception framework has to work for ERP systems, so it's not just the web container. Anyway, for those exceptions that the user can recover from like required fields missing, we catch those type of exceptions, create an ActionError with a message from the bundle specifically for that exception, and then forward back to the input page. This gives the user a chance to fix the problem and resubmit. For the more severe exceptions, we also catch those and forward to a system-error type page since there's probably nothing you can do about it anyway. We use an abstract base action that all of our actions extend. We have all of this behavior in the base action and none of the action classes have to worry about catching these exceptions. The abstract base action implements the perform and has an abstract doWork type method. The doWork method is wrapped with the try catch blocks. Each concreate action class implements the doWork and doesn't have to worry about the try catch. I hope that gives you some ideas. chuck p.s. Regarding your other post about using System.out in your action classes; I wouldn't recommend that approach. Use log4j instead. That way, you can shut off the debug logging externally by just editing the log4j.properties file. At 09:50 AM 1/28/2002 -0200, you wrote: Could somebody help me ?

RE: RES: handling exceptions
Hmm. Just because it appears in the JDK doesn't mean that it is a good thing. The original JSR47 has changed substantially from its original specification due, in no small part, to the efforts of the log4j community. Even so, its current incarnation still pales in comparison to log4j. You might take time to read the criticism of log4j authors and supporters at http://jakarta.apache.org/log4j/docs/srtw.html. The Apache Software Foundation -- you know they host the Jakarta project which includes Struts and log4j, right? -- does not support the JSR. As a user of Struts, imagine for a moment that JDK 1.5 included an MVC implementation similar to Struts but with reduced functionality and limited extension capability. Would you switch just because it was included in the JDK? Aside from functional differences, it is not practical or advisable for everyone to adopt JDK 1.4 as soon as it hits release. For one thing, Sun only releases the JDK for Windows and Solaris platforms. What if you are using Linux? Or AIX? Or HP-UX? Or AS/400? Or any of the other plethora of platforms which Sun does _not_ support? You'll have to wait for vendor implementations which could be months after the JDK release. As developers of application-server based software, most of us are also sensitive to the period of time it takes for the server vendors to support a new JDK. This was rather substantial between 1.2 and 1.3. I'm not optimistic about 1.4. I can't comment on the nested exceptions of 1.4 as I haven't really looked at this. But I would venture that my above comments apply there equally. Part of the benefit of a large and active open source community is that there are multiple solutions to every problem. We are able to evaluate the alternatives and choose a package that most closely meets our needs. Ultimately, one of these solutions may bubble to the top. But that solution won't always show up in the next JDK. And even if it does, that doesn't mean that it then becomes the _only_ solution for the entire community. Choice is a good thing.

Form fields submitted multiple times...
Has anyone ever noticed the Set methods in the ActionForm invoked multiple times (always using the values submitted from the html:form) from Action to Action? In our JSP, we have several buttons pertaining to the same form (thisActionForm). Depending on which button was pressed, a different action mapping is invoked from Struts: action path=/handleButtons type=HandleButtonsAction name=thisActionForm validate=false scope=session input=/home.jsp forward name=updateDetailsButton path=/updateDetails.do/ forward name=resetDetailsButton path=/resetDetails.do/ forward name=calculateButton path=/calculateAmounts.do/ forward name=deleteButton path=/deleteDetails.do/ /action action path=/resetDetails type=ResetDetailsAction name=thisActionForm validate=false scope=session input=/home.jsp forward name=success path=/calculateAmounts.do/ /action action path=/calculateAmounts type=CalculateAmountsAction name=thisActionForm validate=false scope=session input=/home.jsp forward name=success path=/details.jsp/ /action We see the fields entered/changed in thisActionForm set before entering the HandleButtonsAction class. We also see the same field values set again before entering the ResetDetailsAction class, as if the HTML form has been submitted a second time. The ResetDetailsAction resets some date fields on thisActionForm, by invoking various Set methods. We then see the original field values set a third time before entering the CalculateAmountsAction class, clearing out the values reset in the ResetDetailsAction As anyone seen anything similar? Is there an attribute we could use in the action element that would disallow the form from submitting again and again and again? Our current work around is to not use thisActionForm on any other actions, except the HandleButtonsAction, and just grab thisActionForm off of the session in ResetDetailsAction and CalculateAmountsAction, but we feel that there's an easier way.

RE: RES: handling exceptions
I agree choice is good. And Apache Jakarta is one (if not THE) best of them. JBoss is pretty dang fine too. Hats off. I also know that the recruiting marketplace tends to focus on core libs. Loads of projects steer clear of jakarta stuff BECAUSE it is free and open source. I guess my point of view is that it does come down to choice. You must look at the core API's and offerings and you must be aware of how they are evolving. I will personally tend to either write my own or go with the sun libs. This is a time problem. Open source teams are bright, motivated and produce tons of code that is often not well documented. They exert presure on the industry, and I think it's great they do so. But I will choose the core libs, simply because the next job is more likely to use the core libs. Log4j will rapidly change from the only offering, to yet another proprietary (yes I know, think recruiting person) lib. IMHO. It's not religion, it's choice! :) Jonathan Message History From: Cakalic, James [EMAIL PROTECTED] on 28/01/2002 11:04 EST Please respond to Struts Users Mailing List [EMAIL PROTECTED] To: 'Struts Users Mailing List' [EMAIL PROTECTED] cc: Subject: RE: RES: handling exceptions Hmm. Just because it appears in the JDK doesn't mean that it is a good thing. The original JSR47 has changed substantially from its original specification due, in no small part, to the efforts of the log4j community. Even so, its current incarnation still pales in comparison to log4j. You might take time to read the criticism of log4j authors and supporters at http://jakarta.apache.org/log4j/docs/srtw.html. The Apache Software Foundation -- you know they host the Jakarta project which includes Struts and log4j, right? -- does not support the JSR. As a user of Struts, imagine for a moment that JDK 1.5 included an MVC implementation similar to Struts but with reduced functionality and limited extension capability. Would you switch just because it was included in the JDK? Aside from functional differences, it is not practical or advisable for everyone to adopt JDK 1.4 as soon as it hits release. For one thing, Sun only releases the JDK for Windows and Solaris platforms. What if you are using Linux? Or AIX? Or HP-UX? Or AS/400? Or any of the other plethora of platforms which Sun does _not_ support? You'll have to wait for vendor implementations which could be months after the JDK release. As developers of application-server based software, most of us are also sensitive to the period of time it takes for the server vendors to support a new JDK. This was rather substantial between 1.2 and 1.3. I'm not optimistic about 1.4. I can't comment on the nested exceptions of 1.4 as I haven't really looked at this. But I would venture that my above comments apply there equally. Part of the benefit of a large and active open source community is that there are multiple solutions to every problem. We are able to evaluate the alternatives and choose a package that most closely meets our needs. Ultimately, one of these solutions may bubble to the top. But that solution won't always show up in the next JDK. And even if it does, that doesn't mean that it then becomes the _only_ solution for the entire community. Choice is a good thing.

Any code base that implements another code base is, by definition, limited and frozen in time, as a requirement of implementing it. For example, as much as I enjoy the productivity of Expresso, as a Struts implementation it is a 1.0, or whatever version the contributors implement for that release of Expresso that I am using at the time. :( Another example is SOAP, which I would like to use one of Apache's versions. But without all the potential parser conflicts worked out between versions of SOAP, Tomcat, Xerces, etc, it can be a challenge. So I am trying Apache XmlRpc instead, for the moment.

Formatting Dates, Integers...
Hi fellows, I have searched the mailing list in hope to find a way to display a number in format (e.g:120.200,32). I couldn't find any solution. There were some messages proposing to play on the getter and setter methods. But, this is not a solution we imagine. Because we have some object properties in the Form Bean and their properties can be set by struts directly. So changing getter and setter methods requires tons of effort to modify our data classes and form beans which is of course NOT desirable. I also know that there is a DateTag library of Jakarta, which is yet in beta release. Therefore, my managers (regards to them) don't want to use beta releases. They don't want to modify struts tags neither. However, I believe this is quite straightforward way (hopefully they will be contended soon). So, 1. Do you have any clever solution for this common problem? 2. What necessary steps should I take in order to add a new Format attribute to the form:text and bean:write? 2.1 In case, I added necessary methods, how can I guarantee that struts set this formatted value to the property. According to my tries, it doesn't set them correctly? 2.2 How long does an ordinary developer require to modify struts to do so? thanks and my best regards, fehmi. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

I also will have a jsp that displays a purchase request form. Based on other actions the user has taken in the application, much of this form will be pre-filled. If I was doing a standard useBean, when displaying the purchase request form to the user via a jsp, the jsp would among other things iterate through the collection dynamically creating form fields, and populating the form with the contents of the PR bean. For example if the PR had four products, and let's say that one of the attributes of a product is a part number, the jsp would dynamically create fields named partNumber.1, partNumber2, etc..., and fill in those values on the form. My question is whether or not it is possible to do this with form beans, or should I stick with my current plan and not use a form bean in this case, just using another class to do the form validation? 1. Can you model one-to-many relationships, or any other kind of dynamic content, with form beans? 2. Upon displaying this jsp, to make sure I get it populated correctly, in the preceeding action would I simply create a new instance of the Form bean, copy the data from the PR bean to the Form bean, and then place the Form bean in the appropriate scope before forwarding on to the jsp?

RE: What happens when our session expires?
That's right. Check out the javax.servlet.http.* API. You want to register
the moment the user becomes unbound from a session so you can write the form
values to the database (these would be stored as session attributes and
updated as the user moves from field to field in the forms or from form page
to form page. Any object that implements the HttpSessionBinding Listener
interface is notified when it is bound and unbound from a session. So, for
example, create a helper class or stick a helper method in your controller
servlet to do something like:
public void valueUnbound( HttpSessionindingEvent event) {
[plug session.getAttribute() returns into update parameters on your
Statement().update() method call through your Connection() String]
}
This works because whenever this interface is implemented, its valueBound()
and valueUnbound() methods are invoked whenever a session begins and
whenever it ends, respectively. This is how many persistent shopping cart
apps work (e.g., see the JavaOne shopping cart at java.sun.com - it persists
across sessions).

Hi, I have a jsp page which contains the following logic:iterate: logic:iterate id=product type=com.myCompany.myPackage.Product name=productArrayList tr tdbean:write name=product property=name filter=true//td tdbean:write name=product property=desc filter=true//td /tr /logic:iterate productArrayList is a session variable holding an ArrayList object for com.myCompany.myPackage.Product classs. This page works just fine when it is by itself. However, when I use it as part of another page using Struts template, the logic:iterate / doesn't work any more. The template setting is ok as everything works just fine when the logic:iterate / part is removed. Any ideas? Thanks.

Consider double-checking that productArrayList is in fact a session-scope object (or request-scope), and not a page-scope object. If it's page-scope, then it won't be visible to included pages.

RE: RES: handling exceptions
Just to clarify one step further, while Sun _does_ release JDK ports for x86 Linux, that is not the _only_ platform on which Linux runs. Linux is also available on: Alpha (DEC) ARM Hitachi SuperH HP PA-RISC IBM iSeries (aka AS/400) IBM zSeries IBM S/390 MIPS (DEC, SGI and others) Motorola 68K (Atari, Amiga, Mac) PowerPC (IBM pSeries, PowerMac) Sun SPARC Transmeta IBM's port of Linux to its mini and mainframe lines is actually quite promising. But Sun doesn't support it with a JDK release. IBM will no doubt do this just as it has with it's other hardware platforms. But I doubt that such releases will occur concurrently with Sun's JDK releases -- given the historical track record.

That's right. Check out the javax.servlet.http.* API. You want to
register
the moment the user becomes unbound from a session so you can write the
form
values to the database (these would be stored as session attributes and
updated as the user moves from field to field in the forms or from form
page
to form page. Any object that implements the HttpSessionBinding Listener
interface is notified when it is bound and unbound from a session. So, for
example, create a helper class or stick a helper method in your controller
servlet to do something like:
public void valueUnbound( HttpSessionindingEvent event) {
[plug session.getAttribute() returns into update parameters on your
Statement().update() method call through your Connection() String]
}
This works because whenever this interface is implemented, its valueBound()
and valueUnbound() methods are invoked whenever a session begins and
whenever it ends, respectively. This is how many persistent shopping cart
apps work (e.g., see the JavaOne shopping cart at java.sun.com - it
persists
across sessions).

There you go! That sounds good. So I'm assuming (bare with me, I haven't

A questions about pre-population data in a form
The problem that i am seeing is that i have a class that loads data from a
database that creates an FormBeanObject (Depending on the type of formbean
passed in). The code works. But for some reason the formbean no longer
fills the html:text fields on the page. I have tried to reset it back to
the page by using
pageContext.setAttribute(pressReleaseForm, pressReleaseForm);
But it did not work. The reason i am doing this and not calling the action
is that i am also using vignette and i can not call the action from the
front end of vignette.

class=com.ba.corp.forms.pressReleaseForm /

String id = 4;
Connection con = dbCon.getConnection(content);

id = 0;
} else {

Re: XML/XSL and Transformation - My Solution
Hi Matt, I had a similar problem in that I wanted a framework that would allow me to write Struts Actions that pump out XML and convert them to XSL. I looked for a while to find something that did what I wanted. Cocoon2 was close but not quite what I was looking for. In the end I rewrote Struts to support xml and xsl transformations, called struts-stxx. You can download it here, http://www.openroad.ca/opencode/index.html Let me know if you find it useful. This is how it works: - In the struts-config.xml file, you add an new tag, nested under the forward tag called transform will contain the xsl file to transform the Action classes XML against. (You can specify zero-many transform tags). The transform tags can be specific to a particular user-agent if you'd like, or a default one. - In your Action class you would run your business logic as usual. Then once that is complete, you would create an XML document of the output (using JDOM) and assign it to the Actions new class variable Document - The ActionServlet will take the Actions XML, check the browsers user-agent and determine what XSL file to transform against. The resulting HTML is sent back to the broswer. Currently, struts-stxx does not support sending the xml back to the browser to do client side xsl transformation. That's one of my planned features that I have not got around to implementing yet. List of changes to the struts code: - struts-config.xml gets: !-- the transform tag defines the browser user agent to match against to run a particular xsl file -- actionpath=/menu type=com.oroad.mail.actions.MenuAction scope=request forward name=success transform name=default path=/menu_default.xsl/ transform name=Mozilla path=/menu_netscape.xsl/ transform name=MSIE path=/menu_ie.xsl/ /forward /action - org.apache.struts.action.Action gets: A document (JDOM) class variable to store the XML created in an action class. - org.apache.struts.action.ActionTransform and org.apache.struts.action.ActionTransforms (basically modified org.apache.struts.action.ActionForward(s) classes) - org.apache.struts.action.ActionServlet gets: processActionTransform which basically handles getting the correct xsl file for the user agent being passed in, does the transform on the action.document variable and dumps the resulting html(or whatever) to the client. Hope this helps, Jeff Matt Raible wrote: Thanks to everyone who has contributed to this thread. I've been advocating client-side XSL to myself for a few months now, but discovered a fairly major roadblock this morning - client XSLT does not work on the latest version of IE on the Mac (5.1). I've tested this and found supporting information at http://www.hut.fi/u/hsivonen/os-x-browsers.html. Therefore, I will be doing server-side styling as many of you suggest. My initial go around will involve trying to use the Standard Tag library to wrap my XML that I emit from JSPs. I figure it's better to use my JSPs w/ XML for the view so I can get labels from ApplicationResources, and use html:form to do the retrieval of values from my beans. One concern I have with this type of transformation is that it's easy to pick the stylesheet with clien-side styling. For instance, with client-side styling, you can do: ?xml-stylesheet href=default.xsl type=text/xsl? ?xml-stylesheet href=wap.xsl type=text/xsl media=wap? And I don't think this is possible with the current JSTL. Maybe so, I'll have to check. Any further comments are appreciated.

pre-selecting multiple selects
Hi all, I've written an input form that uses a multiple html:select. The user selects the options they want and these options are subsequently inserted into the database. The problem is, that due to an apparent limitation of the html:select value property, if I want to use it to update the database, that is, I want the user to both be able to de-select existing selections as well as select new ones, I don't seem to be able to. This is due to the fact that the value field can only take a single value! That is, I can set the value to -1, so that each pre-selected field is set to -1, but if these are re-selected I have no way of telling which record was re-selected! And if it was de-selected I can't tell which record I should delete! I want to be able to pass a Collection object bean to the value field instead, so that all values in the Collection object are pre-selected so that these values are also meaningful when passed back to my Action (or not). I would love some feedback from anyone that may have a work-around for this, if not it is a serious limitation of the html:select tag. regards, Paul
