Why need to remove FormBean ??
The Action objects that are in the struts-example removes the form bean regardless of whether it is held in the request or session object. If it is held in the request object, why is it necessary to remove it? Doesn't the request object get destroyed between requests (hence destroying the form bean)?

RE: Creating html:hidden ... dynamically
We plan to store bean data has hidden form objects , so that it could be
passed to the subsequent pages, without having to make the scope of the
beans to be session. We do not know how many attributes the bean objects
can have, and plan to store it in an array of hidden form objects like
this.
How about using a Tag to generate the hidden fields for each of the beans
properties.
I have written the following StoreBeanTag which does this.

Roughly 1 out of 10 or 20 times I submit the form that contains File upload. I have not been able to identify a pattern when this exception happens. But I think the exception happens only when no file is actually entered/uploaded. To elaborate, my form has several Submit buttons. Only 1 of the submit button expects the type=file field to have a valid file name. All other submit buttons dont care about the field. When I click on one of these other submit buttons, I get the above exception, intermittently. 2. The tag struts:multibox does not work well in a form that has enctype=multipart/form-data. Only the last checkbox that I selected is set in the multibox form field. I expect a comma separated list of the value of all the selected checkboxes.

Tomcat with Struts

Please respond

Hi Darren,
we're using VAJ 3.5.2 Enterprise with Tomcat and Struts. First we tried to
run Struts 1.0b1 with Tomcat Test Env 3.1 but unfortunately Struts does not
work with Tomcat 3.1's XML-Parser. If you want you can make a XML
(javax.xml.*) SQL (javax.sql.*) package and put it into Tomcats ./lib
directory and add it to VAJ's classpath. But if you use Tomcat 3.2.1,
struts works out of the box - but not that comfortable as the Tomcat Test
Env does, e.g. you can't debug JSP and Servlet Code anymore :(((
I did a hack (in Tomcats WebReaderXML.java to enable "jspPageCompiler"
again) and added "com.ibm.ivj.tomcat.IJVJavaCompiler" again to re-enable
in-workspace JSP and Servlet Debugging.
Running Tomcat 3.2.1 in VAJ 3.5.x
~~~
In short:
0.) Prerequisites:
* latest jakarta-servlet-api _source_
* tomcat 3.2.1 binary distribution (includes ./src already)
* Tomcat 3.1 Test Environment from www.ibm.com/vadd (to get
"com.ibm.ivj.tomcat.IVJJavaCompiler.java")
* struts 1.0b1 source distribution
1.) Install Tomcat 3.1 Test Environment look into
/path/to/vaj35/ide/features/com.ibm.ivj.tomcat/... to find
IVJJavaCompiler.java
2.) Start VAJ, do _not_ "Add feature Apache Test Env 3.1"!!!
3.) Create new Package, e.g. Apache_Tomcat_321
4.) Import all source from jakarta-servlet-api (do _not_ use servlet-api
from VAJ or other precompiled javax.servlet.* - classes; they _must_ be
compiled within VAJ Workspace to enable debugging of your own servlets and
JSPs) into your Project
5.) import following -- compiled classes (not source!) - from jasper.jar
and webserver.jar (both in tomcat-3.2.1/lib/)
jasper: all .class
webserver: org.apache.tomcat.logging.Logger,
org.apache.tomcat.logging.LogHelper, org.apache.tomcat.util.SimplePool
If VAJ still complains about missing classes (you see this in "All
Problems" - Tab) import compiled .class files from ./lib/*.jar until VAJ is
happy.
6.) create two classes: StartTomcat StopTomcat (code is the same for
both!)
public class StartTomcat {
/**
* StartTomcat constructor comment.
*/
public StartTomcat() {
super();
}
/**
* Starts the application.
* @param args an array of command-line arguments
*/
public static void main(java.lang.String[] args) {
// Insert code to start the application here.
try {
Class aClass = Class.forName("org.apache.tomcat.startup.Tomcat");
java.lang.reflect.Method method = null;
Class[] argsClass = new Class[] { String[].class };
method = aClass.getMethod("main", argsClass);
Object object = null;
Object[] arguments = new Object[] { args };
method.invoke(object, arguments);
} catch (Exception e) {
System.out.println("Exception occured: " + e.getMessage());
e.printStackTrace();
}
}
}
Right click StartTomcat in VAJ and goto "Properties-Classpath": have

Hi Darren,
we're using VAJ 3.5.2 Enterprise with Tomcat and Struts. First we tried to
run Struts 1.0b1 with Tomcat Test Env 3.1 but unfortunately Struts does not
work with Tomcat 3.1's XML-Parser. If you want you can make a XML
(javax.xml.*) SQL (javax.sql.*) package and put it into Tomcats ./lib
directory and add it to VAJ's classpath. But if you use Tomcat 3.2.1,
struts works out of the box - but not that comfortable as the Tomcat Test
Env does, e.g. you can't debug JSP and Servlet Code anymore :(((
I did a hack (in Tomcats WebReaderXML.java to enable jspPageCompiler
again) and added com.ibm.ivj.tomcat.IJVJavaCompiler again to re-enable
in-workspace JSP and Servlet Debugging.
Running Tomcat 3.2.1 in VAJ 3.5.x
~~~
In short:
0.) Prerequisites:
* latest jakarta-servlet-api _source_
* tomcat 3.2.1 binary distribution (includes ./src already)
* Tomcat 3.1 Test Environment from www.ibm.com/vadd (to get
com.ibm.ivj.tomcat.IVJJavaCompiler.java)
* struts 1.0b1 source distribution
1.) Install Tomcat 3.1 Test Environment look into
/path/to/vaj35/ide/features/com.ibm.ivj.tomcat/... to find
IVJJavaCompiler.java
2.) Start VAJ, do _not_ Add feature Apache Test Env 3.1!!!
3.) Create new Package, e.g. Apache_Tomcat_321
4.) Import all source from jakarta-servlet-api (do _not_ use servlet-api
from VAJ or other precompiled javax.servlet.* - classes; they _must_ be
compiled within VAJ Workspace to enable debugging of your own servlets and
JSPs) into your Project
5.) import following -- compiled classes (not source!) - from jasper.jar
and webserver.jar (both in tomcat-3.2.1/lib/)
jasper: all .class
webserver: org.apache.tomcat.logging.Logger,
org.apache.tomcat.logging.LogHelper, org.apache.tomcat.util.SimplePool
If VAJ still complains about missing classes (you see this in All
Problems - Tab) import compiled .class files from ./lib/*.jar until VAJ is
happy.
6.) create two classes: StartTomcat StopTomcat (code is the same for
both!)
public class StartTomcat {
/**
* StartTomcat constructor comment.
*/
public StartTomcat() {
super();
}
/**
* Starts the application.
* @param args an array of command-line arguments
*/
public static void main(java.lang.String[] args) {
// Insert code to start the application here.
try {
Class aClass = Class.forName(org.apache.tomcat.startup.Tomcat);
java.lang.reflect.Method method = null;
Class[] argsClass = new Class[] { String[].class };
method = aClass.getMethod(main, argsClass);
Object object = null;

Re: Antwort: RE: Visual Age 3.5.3 Tomcat with Struts
Dion, I had problems trying to configure the WTE. The documentation in VAJ was lousy in my opinion. I was able to get the default application working with WTE, access the samples, etc., but had troubles attempting to create an additional webapp. I followed the instructions in VAJ help for creating an additional webapp, but got an exception when reloading the servlet engine. The problem wasn't obvious, so after trying several different permutations of changes, I gave up. It may have been something simple, but I ran out of ideas on how to debug the configuration. Also, it seemed that the layout of directories, etc for WTE was different than a standard j2ee webapp structure. (e.g. the default app had no WEB-INF). I kind-of prefer open-source, j2ee compliance, etc. - Darren. dion@multitas k.com.au To: [EMAIL PROTECTED] cc: [EMAIL PROTECTED] 04/30/01 Subject: Re: Antwort: RE: Visual Age 3.5.3 Tomcat with Struts 10:39 PM Please respond to struts-user Is there a reason you don't want to use the WebSphere Test Environment in 3.5.3? -- dIon Gillard, Multitask Consulting Work: http://www.multitask.com.au NetRexx: http://www.multitask.com.au/NetRexx.nsf Darren_James@ i2.com To: [EMAIL PROTECTED] cc: 01/05/2001 Subject: Re: Antwort: RE: Visual Age 3.5.3 Tomcat with Struts 01:14 PM Please respond to struts-user 1.)

Shopping Cart Project
Hi guys ! Well. Ok. So there's no Shopping Cart example utilising struts out there. And although it's been done so many times using other languages and frameworks, it's time to put one together for the struts community. After all, the 'shopping cart' is really the 'hello world' for web apps !! It will make a great foundation for struts newbies and hopefully decrease the learning curve a little. It may also allow the struts veterans to show off some of the advanced concepts. Who knows, it may even be added to the struts distribution as an advanced example! Is anyone interested in contributing to this ? What are some thoughts ? If I get enough people on board, then I'll set up a CVS (source control) server and get the project underway !

RE: Creating html:hidden ... dynamically
You could use html:hidden property=hidden[1] value=value1/
Look at the struts-documentation for indexed properties...
Your getter/setter methods use an int parameter...
String getHidden(int index){}
and
void setHidden(int index, String value){}
Any help?

Re: Iterate certain number of times?
Levi, Thanks for your thoughts. However, I believe I am doing things correctly as follows: this page displays a formatted version of a logfile on the server. This logfile can be up to 50 MB in size, and a filtering mechanism is provided so the user can browse the whole file, or certain categories of log entries. Obviously, with a file of this size, it is not feasible to load it all into memory at one time, and use a pager tag to display it. Instead, I do the necessary filtering, and create a list of file pointers to the log entries the use wishes to see (things are further complicated as the variably length log entries have to be reversed to display in chronologically descending order, instead of ascending). When the user requests the next page, the next chunk of log entries are retrieved from the file through the action and displayed. Everything is working nicely, and I want to put the finishing touches on it to simply display links to each page, rather than just next and previous. In my initial action I calculate how many pages I have etc. and simply want to do a for loop to create the links. As Niall pointed out, I could load these page numbers into a Collection and then use the iterate tag, but this seems to be be overkill. Is there really not a Struts tag to do a for loop?!!! If not, I belive that it is a major lack. Are there any plans to introduce one, maybe when the logic tags are improved? Thanks. Any other ideas gratefully received!

Of course I have no idea what your system actually looks like, but I would question its retrieving data all the way up to the view layer and then not displaying it. If possible I would reconsider the design of the controllers responsible for constructing the Collection you are interested in iterating over. Consider the following method signatures in a hypothetical controller for searching a product catalog: public Collection findProducts(ProductInfo searchCriteria) vs. public Collection findProducts(int startIndex, int count, ProductInfo searchCriteria) vs. public Iterator findProducts(int startIndex, int count, ProductInfo searchCriteria) I would expect the first to return a collection of every product in my entire system. I believ this is probably what your system is doing and I wouldn't consider it especially useful in a controller responsible for supporting a view. The second approach introduces a bit more flexibility by allowing the view the decide how many products its interested in displaying. The third approach is probably what I would prefer, I think it just clarifies the intent of the method for view builders.. Might be a little stronger form of encapsulation too.

Where to forward when validate returns false in wizard style forms?
Hello, I may not understand properly the way struts deals with things when validate=true in the action mapping, so please bear with me. I have a wizard style input form(s) all using the same Action. Most of the time, the Action will only forward to the next page. Only at the last page will the Action perform its work. I want to take advantage of struts' automatic validation of FormBeans. I believe, if I set validate=true, then if validate returns false, struts will automatically forward back to the input page (as specified by the input attribute of the action-mapping element). It seems that this will not work properly for a wizard style approach. This is because the input page changes for every step in the wizard process. Has anyone else dealt with this problem? Do I have to manually perform the validation myself inside the Action? Would it be better to just have an Action for every step in the wizard process?

Yes, it would be better to have an action for each step in the process. That is what MVC/Model 2 is all about. Thanks for the reply! That's the same conclusion I came to. What I'm trying is having the same Action class handle each step, since for the wizard style all but the last step only forward to the next phase.

Returning from a form apge
In our web application, we have two pages from which a user can access a third page. From the third page (which is form to fill out and save), the user either saves or cancels their action, and the user is returned to the page from which they originally started. However, the third page has no knowledge about where it came from so it doesn't no who to forward to when its action is complete. I'm not sure how best to handle this situation. One option would be to use a parameter on the link to the third page with a value indicating the page to return to. However, I'm using an html:link tag which is passing other object related parameters on to the third screen (the form uses this information to populate itself). What I would like to do is get the parameters from the object and then append another parameter which indicates the page to return to but I can't do that and use the link tag. I'm toying with the idea of building a custom link tag which also takes a return attribute. This tag would put the return information in the parameter list that gets generated. Before I do that, however, I'm wondering what other ways people have used to address this sort of problem?

Hi all I'm working my way through struts-example and the documentation and I am confused about the process a form tag takes to create an ActionForm bean if one doesn't exist. There seems to be conflicting documentation. The walking tour of the example says. First, the logon.jsp makes use of the custom-tag form. This tag can scan the application's properties for a form bean related to the path /logon.jsp (from the link on the welcome page). Which sounds the same as the html tag libray guide which says: The name of the bean and its class can be specified as a property to the form tag, but may also be omitted. If omitted, the ActionMappings database (loaded from the struts-config.xml file) is consulted. If the current page is specified as the input property for an action, the name of the action is used. The type property for the bean is also then taken from the configuration, via a Form Bean definition. But the html tag library reference says this for the name attribute of the form tag: Name of the request scope or session scope bean (as defined by the scope attribute) whose properties will be used to populate the input field values. If no such bean is found, a new bean will be created and added to the appropriate scope, using the Java class name specified by the type attribute. If this attribute is not specified, it will be calculated by using the value of the action attribute to look up the corresponding ActionMapping element, from which we will select the specified form bean name. So in struts-example/login.jsp, does it find a correct action mapping because there is a mapping with path=/logon which is the same as the form tag action attribute or does it find it because input=/logon.jsp which is the jsp url? If the ActionForm bean is created in a form tag rather than in an action bean earlier, do the request parameters not get updated to the bean? I notice that if I go directly to login.jsp and append ?username=ross to the url, then this does not appear in the textbox. Slightly off topic but do I understand correctly that the reason why the login link in struts-example/index.jsp goes directly to login.jsp rather than login.do is because in the case of a login form we don't want to display anything initially in the boxes. That is the main thing that's different between login and other forms in the example. Usually we would go to an action instead of a jsp directly? Thanks Ross __ Do You Yahoo!? Yahoo!

RE: New User [ERROR IN BaseHandlerTag FormTag]
Thanks ! Jean, But i got it working through a different XML Parser. Yes!! That styleId attribute is a new edition Sanjeev -Original Message- From: Jean-Noel Ribette [mailto:[EMAIL PROTECTED]] Sent: Monday, April 30, 2001 11:08 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: New User [ERROR IN BaseHandlerTag FormTag] I'm affraid this error comes from an error in the cvs. The attribute styleId was introduced in the class BaseHandlerTag of the deprecated org.apache.struts.taglib package and not org.apache.struts.taglib.html (same for FormTag) on the 18th (http://www.mail-archive.com/struts-dev@jakarta.apache.org/msg01153.html) Can any commiter correct this ?

RE: Returning from a form apge
Title: RE: Returning from a form apge If you are using the MVC design pattern then you will have an action associated with the save. What I have done is keep a hidden field for the referring page, which keeps track of the mapping key. This way I am able to forward to the jsp that originally started the action. -Original Message- From: James Howe [mailto:[EMAIL PROTECTED]] Sent: Monday, April 30, 2001 11:44 AM To: [EMAIL PROTECTED] Subject: Returning from a form apge In our web application, we have two pages from which a user can access a third page. From the third page (which is form to fill out and save), the user either saves or cancels their action, and the user is returned to the page from which they originally started. However, the third page has no knowledge about where it came from so it doesn't no who to forward to when its action is complete. I'm not sure how best to handle this situation. One option would be to use a parameter on the link to the third page with a value indicating the page to return to. However, I'm using an html:link tag which is passing other object related parameters on to the third screen (the form uses this information to populate itself). What I would like to do is get the parameters from the object and then append another parameter which indicates the page to return to but I can't do that and use the link tag. I'm toying with the idea of building a custom link tag which also takes a return attribute. This tag would put the return information in the parameter list that gets generated. Before I do that, however, I'm wondering what other ways people have used to address this sort of problem? (I assume that I'm not the only person to have encoutered this situation) Any tips or suggestions would be appreciated. Thanks.
