So, should I do this?

AccountHTML_jsp


com.mydomain.AccountHTML_jsp

   
   

   AccountHTML_jsp


   /AccountHTML.jsp

You don't change your "struts-config.xml" at all to use precompiled JSP pages.
You do have to change your "web.xml" file, however, to include the servlet
mappings for the generated servlets.  You also have to include the generated
and compiled servlet class files in your WAR file.

Re: Forward to a servlet

[Billy Ng]

Interesting!  Tell me if I am wrongly interpret your message.  Do you mean I
should deploy the precompiled jsp files to
tomcat/work/standalone/localhost/myApp ?  If not, how does the servlet
container, tomcat, know I have already precompiled the jsp files when the
forward tag points to the jsp files?

Iterate over form bean

[Mohan Radhakrishnan]

Hi,

   I am trying to iterate over the form bean found in request scope. The
property 'x' is of type String[].

  





And I get this error.
org.apache.jasper.JasperException: Cannot find bean item in scope null

 Am I doing something wrong ? Do I have to use the FORM_BEANS_KEY ? 
  Appreciate any ideas.

Struts-config.xml

[usha]

Hi

I am new to the Struts, testing some sample applications. we want to 
implement the struts in our existing project. right now we have almost 
50 tables and more than 200 submittion pages. what my concern about the 
struts is if i have to configure all the form beans and the action 
mappings the struts-config.xml will become large file. is there any way 
i can create new configuration file and the action servlet class referes 
to this config.xml. what i mean is can i divide into different config files.

Thanks

RE: [OT] Overloaded setters in JavaBeans

I looked all over for an example.  I read the docs and even tried to

public MethodDescriptor[] getMethodDescriptors()

  MethodDescriptor rv[] = null;
  try
  {
Method setEmailString = beanClass.getMethod("setEmail", new Class[]
{String.class} );
Method setEmailForm = beanClass.getMethod("setEmail", new Class[]
{EmailForm.class} );
Method getEmail = beanClass.getMethod("getEmail", new Class[] {});
Method setName = beanClass.getMethod("setName", new Class[]
{String.class});
Method getName = beanClass.getMethod("getName", new Class[] {});
Method[] methods = new Method[] { setEmailString, setEmailForm,
getEmail, setName, getName };

rv = new MethodDescriptor[methods.length];

The implementation of java.beans.Introspector (which is what BeanUtils
uses under the covers) has always interpreted the "discover a matching
pair" restriction to mean "discover a matching pair and ONLY the
matching pair; i.e. no other methods by the same name".

Note that you can actually use overloaded setters if you want to, but
you're going to have to go to a fair amount of effort.  Essentially,
you'd need to provide a BeanInfo class for each of your beans that
declared what the actual Method implementations of the getter and setter
are for each property.

RE: multiple file upload

[Daniel Joshua]

>2. I can create file button in loop so it can be added as per requirement.

I do not think that you can set multiple FormFile using one name. I think it
is some sort of limitation of the Strut framework, but you can always
provide that functionality yourself.

How about loading 1 file at a time, like the way HotMail works.

Anyone else have a good way of handling a varible number of files to be
uploaded?

Daniel

Subject: multiple file upload


My requirement is to upload some files, the no of files are not known as the
user can add no of files to be attched/uploaded.

So, I have two options for doing that -

1. I create the file button dynamically with different name, but in this
case how can I add that parameter in form bean.

2. I can create file button in loop so it can be added as per requirement.
But, in this case the name of file button will be same.

I would like to go for 2nd, as it looks easy to implement. But the problem
is that I am not sure if struts can handle such situation where there are
multiple file button with same name.

Any help will be appreciable.

Amit.

That's actually simple ... the  tag does not create a
scripting variable.  It only stores the current element you are iterating
over in the attribute defined by "name".  Scripting variables are only
needed if you're going to use scriptlets or runtime expressions, and in
general that (especially scriptlets) is discouraged.

NOTE:  When you start using JSTL, you'll find that the iteration tags in
that library act the same way.

Okay, here is what did it.

  



So I have to user bean taglib to access a bean inside of an interate tag
?
I can't just access it by using <%= myMess.getSubject() %> ???

I can live with that, I just don't understand why...

Hello,I installed struts-sample on Webshpere 5.0 application server and only took me 
10 minutes. I used Administrative Console from web browser. 
Go to Applications -> Install New Application. Browse the struts-example.war in my 
Local Path and type in struts-example in Context Root. Click next. And next again. 
Check web module. And next and next. Then done!.
It's a lot easier to install the example in websphere 5.0 than 3.5.

Iterate tag Tomcat 4.1.12, issue or no?

[Mark Conlin]

 
After much scanning of the user-list archive I have seen some mentions
of a problem with tomcat 4.1 and the  tag.
I have also seen mentions of Tomcat 4.1.12 working fine with the logic
tag. Does a problem exist?
 
I am getting the following error, my code matches the example code in
the  taglib guide, so I am out of ideas on what is wrong.
 
ERROR:
cannot resolve symbol symbol : variable myMessage
 
Code in JSP:
<%
  SessionUtility su = new SessionUtility();
  ArrayList messages = 
(ArrayList) su.getAttribute(session, HomeConstants.MESSAGE_ARRAY);
%>
 



   

<%= messages.size() %>


<%= myMessage.getSubject() %>

 
If I remove the logic tag completely the messages.size() tells me that I
have two 
Objects in the array list, so I know the information is in there I just
can't get to it.
 
I have also tried this with the type="com.mysystem.bo.bean.Message" set
as well, still
It does not work.
 
Any Ideas?
 
Thank you for your help,
Mark 

logic:iterate

[Cathy]

Hi:

Have you used pager tag library from http://jsptags.com/tags/navigation/pager/
with logic:iterate tag? I am using them together, and I have a problem. Please help me 
if you know what's going on in the following problem. I really appreciate your 
help.(Rick suggested me to use display tag from 
http://edhill.its.uiowa.edu/display-0.8/. I had a look. And it's excellent. However, 
the project is almost in production phase, I prefer to fix the problem based on what I 
have now instead of changing the implementation. Thank Rick, anyway).


I retrieved 23 rows from Database, and I saved the data in session. I want to display 
the data on 10 rows/page basis with page navigation ability.So on the first page, 
there are 10 rows and a "next" link, On the second
page, there are 10 rows and  "previous" and "next" link. On the third page, there are 
3 rows and a "previous" link. I used logic:iterate to iterate through the data, and 
use pager tag library from the above link to implement the page navigation ability.The 
following is my jsp snippets:

<%@ taglib uri="/WEB-INF/pager-taglib.tld" prefix="pg" %>
..


   

   
 
  
 

 
 
 
 
 
   

   

<-- page navigation area-->


Page navigation works fine(I mean when I click "next" or "previous", it goes to next 
or previous page. So I omitted the page navigation snippest. The problem is: when the 
first page is displayed, I viewed the source of the first page, there are 10 blank 
rows before the line " <-- page navigation area-->" -- I mean there is a big spaces 
which is equal to 10 rows, between the last row and the line " <-- page navigation 
area-->". After I click "next" link and opened the second page, I viewed the source, I 
found between the last row on the page and  the line "<-- page navigation area-->", 
there are 3 blank rows(because the next page has 3 rows). When I opened the third 
page(last page), and viewed source, there is no blank row(because there is no next 
page).

In order to solve the problem, I searched the archive and the web. I found lot of 
disussion about paging. But there seems no discussion about the blank rows problem. 
Could you help me out here. I spend a lot of time trying to fix it, but no clue. I 
really appreciate your help.

Thank you very much.

RE: Move to TilesRequestProcessor results in forwarding exception.

[Jerome Jacobsen]

If I specify a Tiles definition file I must supply at least one definition.
Otherwise I get this:

org.xml.sax.SAXParseException: The content of element type
"tiles-definitions" is incomplete, it must match "(definition)+".

So my Tiles definition file looks like:


 


The file layouts/dummyLayout.jsp does not actually exist.  However I seem to
get no errors at runtime.  So I think I've got the right configuration now
to proceed with a refactoring toward Tiles.  Whew!

Re: question

Figured it out, I needed to add:

session.setAttribute("list", list);

To my ActionBean

but this does not work.

Any help will be greatly appreciated.

Re: Error handling (ServletException)

[Dan Tran]

Your action throws an Exception which got rethrow as ServletException by the
controller if the original exception is not caught by your handler.

So you need to change your configuration to catch Exception ( or whatever
the real one is) not ServletException.

Hope this helps.

Re: [FRIDAY] Best error message ever

[Max Cooper]

I don't think this will trump any of the fine examples posted so far, but I
have always found this gsu error message amusing:

gsu: you won't be doing that today.

This is what you get if you try to gsu to an account that you don't have
access to.

Error handling (ServletException)

[Pete Gieser]

Is there something special I have to do to handle a ServletException?
No matter what I try, the stack trace always seems to be sent to the 
standard Tomcat error page.  

I've tried configuring  in struts-config, but that
doesn't seem to work.  What's the secret?

  

  

javax.servlet.ServletException: BeanUtils.populate
at
org.apache.struts.util.RequestUtils.populate(RequestUtils.java:980)
at
org.apache.struts.action.RequestProcessor.processPopulate(RequestProcess
or.java:779)
at
org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:
246)
at
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1292)
at
org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:510)

Thanks!
Pete
