Transforming xml with xsl in custom tag
Hi all, I have the following problem: I have a jsp-page that imports all the struts taglib tlds and contains a call to a custom taglib (). This tag receives data from the db as xml and transforms it with a xsl. The output of the transformation contains struts -tags. Unfortunately these tags never get parsed to html. Of course I could transform the data straight to html but then I would lose the validation benefits etc of struts? What am I doing wrong? Is this feasible at all? Here is a part of the xsl: http://www.w3.org/1999/XSL/Transform";> This is the output I get in the browser: NOK1VEW197 NOK1VEW199 This is what I'd like to achieve (eventually): NOK1VEW197 NOK1VEW199 TIA, Kari --- Kari Pulkka IT/EvliNet Development Evli Securities Plc Aleksanterinkatu 19 A, P.O.

Re: Dynamic Form Beans?
On the input side, it sounds like what you want is a map that is basically a
copy of the map usually used internally by the servlet container to
represent parameters. If you don't mind having copies in the map of what's
also in any explicit form bean fields, you could just use this at the top of
the reset() method in your form bean (or a base class).
HashMap map = new HashMap(); // Actually, this would be an instance
variable
for (Enumeration e = request.getParameterNames(); e.hasMoreElements();)
{
String name = (String)e.nextElement();
map.put(name, request.getParameterValues(name));
}
The output side is a little different because the Struts tags are set up to
look only for explicit fields. There's been at least one proposal for
changing that, though.
However, this is what I refer to as an "uncontrolled" dynamic form bean.
More interesting would be a "controlled" dynamic form bean, where the valid
fields are actually controlled externally, rather than being at the whim of
the request (or other code). But then, that's a bunch more work. :-)

Connection Pool
Hi Gurus, 1. Can someone let me know the steps involved in setting up a connection pool in struts config files? 2. Also a small snippet of code on how to use it from a action servlet. Is it as easy as getting a ref. to a connection pool using JNDI. Your help is highly appreciated. Sanjay
NEW Commercial Struts-powered website
Just appending to the forum to announce a new Struts-based application that we've just launched into production for a Customer last week - http://www.redgalleon.com It's a Melbourne (Australia) based ASP service that matches member's defined preference/permission profiles for restaurants, sporting events, theatre/cinema, etc. to offers that are entered by vendors - these preferences can be very detailed down to cuisine (for restaurants), location (general selection or distance-from-point) and days / times. Once matched, the site will pro-actively email or SMS a notification to the member. Vendors are notified of bookings via logging on to the site, email, Fax (via an email-to-fax gateway) or SMS. This has been a work in progress over around 6 months and is using the 1.0b2 struts release. It's not a 'pure' MVC architecture - a lot of the promo pages are done as straight JSPs with some HTML, but from logon downwards it uses struts/MVC all the way. The site is in production on a Slackware Linux web server connected via JDBC to a Sun E450 Box running Oracle. The site has just been launched in the last week and we are getting around 15,000 hits a day, however we expect much more once we start promoting it to the Mass Media. Further Struts commerical development is on the way - I've also designed and am constructing an eRecruitment application (http://www.i4-talent.com) with a different company that uses a similar architecture to the above site and will be launched within the next few months. This ASP service will allow Recruitment Managers to template job ads, place these ads to their own web site and several other job boards and then track all applications through to the offer process - it's got a lot of smarts built in to code experience, skills, etc. so that a %age fit to a job can be calculated. It also allows each company using it to define their own hiring workflow, making it as complex or as simple as they require... Will notify the forum again when this one goes live..

RE: Struts behind the scene
To be more exact, JSP's are pre-compiled into a special servlet source (java files). The servlets are compiled into classes. There exist mechanism for pre-compiling the JSP to classes, before the first user request is received. You can find these special servlet .java files in the tomcat/work/ directory. There is no rendering mechanism per-say. In the end, the JSP/Java files write information using JspWriter class that subclasses from java.io.Writer. To me, a JSP is just another view of a Servlet, without all the ugly print statements. The reason this is important, is that you can do all those things that servlets can do, well sort of. > -Original Message- > From: Greg Reddin [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, August 29, 2001 2:00 PM > Subject: RE: Struts behind the scene > > > Shelly, > > I'm not sure I fully understand the question, but I'll give it a shot. > > Struts does not generate anything.

Object creation is rather fast, but that doesn't mean caching is always frowned upon. Caching for performance at the enterprise level is really to reduce object initialization rather than object creation. The problem with EJBs, Tags, and Servlets is that they potentially do a lot of up front initialization. All three has to at least read an XML to load some kind of deployment information, and then there are resources (db, networking) that can be allocated by containers or developers. Struts objects generally don't a lot of object initialization, therefore isn't necessarily a really good candidate for caching. Calvin

All, I have a page with a control which allows the user to add items to a vector on a bean. Basically it is a company form with an Add Subsidiary button.

Re: welcome file in web.xml with pre-compiled jsp's? - tomcat bug!!
Just for your information - turns out this is a bug in Tomcat! I submitted it (Bug No 3309) and they propose to fix it, maybe by 3.3.1. At the moment, work around is to stick an uncompiled version in directory, or to use javascript to perform a forward in a regular html page to your pre-compiled jsp. Cheers, Dave
STRANGE: session.invalidate() is not invalidating the session
Hi, I noticed a peculiar thing. In my application I have a logout link on pages. This link control goes to 'Logout' action where I clean up the session variables and then invalidate the session with: session.invalidate(); and this class forwards it to Logout.jsp which just has the goodbye message. I have noticed that at this point if I keep going back with the back key of my browser to the point where jsessionid is part of the URL, i.e., http://localhost:8080/msqc/logon.do;jsessionid=149062E2E0A77480075991317505D453 and do the browser refresh here then I can go back into the application without having to log in again. It is as if the session is still alive. All the screens(incl. the above URL point) going backwards from Logout.jsp do show the page expired message but doing refresh on the above URL screen only brings back the application Could someone please explain this to me? Has anyone else seen this? BTW I am using Tomcat 4.0 and Struts 1.1(same happens with 1.0 too) TIA. -Nimmi
Re: Dynamic Form Beans?
I have the same problem too, and I'm sure there are many more like us. I believe this is a problem struts has not addressed yet. Fortunately, they are working on Dynamic form generation feature for struts1.1. I don't know when it is going to be ready!! Here is a work-around: Make your JSPs without using FormBeans (you should have your won Java classes to dynamically generate the form), and extract input parameters from request in your action and stuff them into a Hashtable for further processing. However, someone should clarify if this approach violates struts recommended architecture. I would definitely like to see a better solution.

Thanks to all that helped me out.
Hi, A big thanks to all that replied and tried to help me get the nightly build working with Tomcat. Although I was unsuccessful, I really do appreciate all the advice. I tried getting the nightly build of struts to work with Tomcat 3.2, 3.2.3, 4 but no luck. I rebuilt my applications to use version 1 of Struts. If it weren't for that iterate tag I would never have gone to a nightly build. I can't wait until the next version of Struts is out. Great work to the Struts team they have come out with an excellent product. Alex = Regards Alex Colic, HBA, B. Ed PopWare Inc. "Driving down the cost of conversions!"

RE: Dynamic Form Beans?
The one idea that I had was to create a new subclass of ActionForm called ActionDataForm. This form would have get and put methods that use keys instead of the usual pattern of numerous getters/setters. For the process of saving form data, we could add a new override to RequestUtils.processPopulate(..) which would take an ActionDataForm instead of an ActionForm as its form instance. Then we would implement this method to use get and put with keys instead of getters/setters. One problem: I don't know how the populate works from the other side (meaning when you want to prepopulate a form based on the contents of a JavaBean in the session, etc.). I imagine that logic is contained in the HTML tag libraries or some other tag library. I guess what I am wondering is that since a number of people have run into this and needed a solution I assumed that there might already be a solution to this problem. If not, maybe we can find a solution and then submit a patch to Struts for 1.1 or something. Anyone else have any thoughts on this? -- John Townsend PS.

2nd attempt: Unexpected behavior of html:options tag
Why isn't this allowed : where variantOptions is a property (of type ArrayList) of cartItem. but this is: IOW if I copy the property into a new bean (with ), I can access the collection. The same happens if instead of using "name=cartItem" I want to access a collection property of the formbean. I need the same workaround.

I am working on a project where is would be nice to have the ability to define a dynamic form bean (i.e. a form bean where the fields are defined at runtime).

Re: Real World Struts
Will, I'm what I would call an intermediate JSP programmer, and switched to Struts recently. The (one man) project I'm currently working on does not require modifications in terms of extending the Struts framework with new factories or the like, but rather focuses on a simple Web interface and internationalization. I'm using struts for about two weeks now, and I reached my milestones fairly quickly. More quickly than if I would have used JSP--which is what I did before. Struts and its taglibs provide excellent support for realizing a Web interface rapidly. I also found the mailing list a valuable resource where I get responses within minutes or hours. Personally, I found the learning curve not quite as steep as it sounds when you describe it. It took me two days to get the basic concepts and realize my first pages. After two weeks I have completed three workflows containing four pages each--including functional test code using httpunit. Plus I'm working 4h days... If your developers have a good understanding of JSP I do not see why they should have problems with Struts. Au contraire, I found this is an excellent basis for jumping into Struts since daily work proofed to require knowledge in both areas. I'm basically using Struts for workflow issues, form handling & i18n, mixing it with JSP when necessary.

RE: Real World Struts
> We have developers who are familiar with JSP and Java and J2EE. Struts would be > the only learning curve ( and it's not exactly a small learning curve ). > I have to disagree with you there. I began using Struts when I had less than 6 months experience in Java, and very little experience in JSP or J2EE. I found it to be very intuitive and useful very quickly. Our team also had little trouble adopting it and understanding it. We spent about a day or two in full-time training, assigned some work, and kept mentors available for a few weeks to help tie up loose ends. After that it took very little time to get people moving. The doc is very clear and one can reasonably learn Struts on their own in a fairly short time. In fact it answers many architectural questions up front, leaving developers to focus only on the business functionality at hand. Things like internationalization, error-handling patterns, separation of logic, etc. are already figured out. Depending on the size of your app, if you don't use something like Struts you will eventually find yourself asking questions like "Should this functionality be in a bean or on the JSP?", or "What's the best way to pass such and such data from here to there?" or "How should I display errors?". Struts offers solutions and patterns for all those things. That's my 2 cents.
Web-app_2.2.dtd
Hello All, We are using struts for our application. One of the problem we have encountered is with the finding of Web-app_2.2.dtd . Seems like the name of the dtd is hard coded in the ActionServlet java class. During deployment of the application (using weblogic) the server waits for like 2 minutes or so before it determines it can not find the dtd since we are running behind the firewall. We are not sure how can we change this behaviour it so that it always look for it locally (instead of going on internet) and save us all the wasted time Sushil

Hi,Depending on what you are trying to do or the scale of the applicationyou are building, you can declare the collection within your jsp pageand put it within the pageContext or you can declare it in your Action subclass and put it in the session. I found the last option to be a neater and better way of doing things. I think it will be a good idea todeclare / define the collection in the Action subclass, incase you needto populate the list from an external source, such as a database. Example 1 (within jsp page, taken from struts example application - subscription.jsp)<% java.util.ArrayList list = new java.util.ArrayList(); list.add(new org.apache.struts.webapp.example.LabelValueBean("IMAP Protocol", "imap")); list.add(new org.apache.struts.webapp.example.LabelValueBean("POP3 Protocol", "pop3")); pageContext.setAttribute("serverTypes", list);%> other code .. labelProperty="label"/> other code ..* The LabelValueBean is a utility class, which is part of the struts example,that creates a bean object. The object contains label value pairs, as thename implies. Example 2 ( within Action subclass )perform method - declared locally (avoid the use of instance variables in Action class).ArrayList list = new ArrayList(); .. other code ...serverTypes.add( new LabelValueBean( , ) );session.setAttribute( "serverTypes", serverTypes ); .. other code ... jsp page. * labelProperty can be omitted if the label and value have the same value. I hope this helps you.Chiji

Re: java.io.NotSerializableException: java.util.HashMap
I figured it out - I was stuffing hashmaps and rowsets into my ActionForms, and then storing those in the session. Because of the clustering configuration we have in iPlanet, this error was being thrown for the reasons you state. I fixed this my moving any non-serializable components into beans only kept in the request.

Re: java.io.NotSerializableException: java.util.HashMap
I don't know what the relationship is between this error and your JSP, but it looks like your container is trying to serialize the session for some reason. Apparently you have a session attribute which is a HashMap, and it doesn't like that because it can't serialize it. -- Martin Cooper - Original Message - From: "Matt Raible" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, August 28, 2001 11:30 AM Subject: java.io.NotSerializableException: java.util.HashMap > I am getting the following error on a JSP page that I am using struts taglibs. > However, I am using Sets and ArrayLists for my - not a hashmap?? > > Any ideas? > > Thanks, > > Matt > > [28/Aug/2001 12:29:20:9] error: Exception: SERVLET-IO_exception: IOException > occurred > Exception Stack Trace: > java.io.NotSerializableException: java.util.HashMap$1 > at java.io.ObjectOutputStream.outputObject(ObjectOutputStream.java:845) > at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:342) > at > java.io.ObjectOutputStream.outputClassFields(ObjectOutputStream.java:1567) > at > java.io.ObjectOutputStream.defaultWriteObject(ObjectOutputStream.java:453) > at java.io.ObjectOutputStream.outputObject(ObjectOutputStream.java:911) > at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:342) > at > com.netscape.server.servlet.platformhttp.PlatformNASSession.putMemberValue(U nknown > Source) > at > com.netscape.server.servlet.platformhttp.PlatformNASSession.saveSession(Unkn own > Source) > at > com.netscape.server.servlet.platformhttp.PlatformHttpServletRequest.saveSess ion(Unknown > Source) > at > com.netscape.server.servlet.servletrunner.ServletRunner.execute(Unknown Source) > at com.kivasoft.applogic.AppLogic.execute(Unknown Source) > at com.kivasoft.applogic.AppLogic.execute(Unknown Source) > at com.kivasoft.thread.ThreadBasic.run(Native Method) > at java.lang.Thread.run(Thread.java:479) > > __ > Do You Yahoo!? > Make international calls for as low as $.04/minute with Yahoo!

Re: static text fields on the session or from??
I would suggest putting them in the form. That way, the form represents all the data required for the view, whether modifiable or not, and you don't have multiple pieces of data scattered around in different places. The data that isn't in input fields won't be populated back into the form, so there's no overhead there. -- Martin Cooper - Original Message - From: "viet nguyen" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, August 28, 2001 5:56 PM Subject: static text fields on the session or from?? > If I need to display a screen which includes both > editable fields and static text fields, would it be > better to store the read-only fields on the session > instead of having them in the form?

Betreff: RE: Logic Tags
I am passing the success (request.setAttribute("success","yes");) parameter
back to the jsp but in the jsp when I try this code:
window.open("welcome.jsp", "popupPage", "top=0,left=0,resizable=yes,
status=yes" + ",width=" + screen.width +
",height=" + screen.height);
the present tag doesn't fire. I can print the success attribute on the jsp
page so I am getting the parameter back to the page.
What am I doing wrong??
Re: struts selection and Javascript onchange question
Hi Robin, Chiji: What I do is to create a Bean (called Option) that I will use to store this properties: optionGroup < The group to which our option is associated (The Country of the Province/State in our case). optionValue < The value of the option (The Province/State code or whatever you'll store). optionLabel < The label the option will display (The Name of the Province/State). So, In my action, for each Province/State I create an Option Object and put it inside a Vector (ie. 'options'), then I put the Vector in request scope (session If you like). After setting my Vector 'options' in request, I create a Javascript Array in my jsp this way (I will use this Javascript Array to fill my options later with a javascript function):
