Wrapping response object .. does it works ??!!

[Hany Al-Shafey]

Hi,

I spent nearly 3 weeks on a response wrapping problem, I didn't yet figured 
out the cause, I'm deploying my web app to JRUN4 server. the problem arise 
when I tried to filter struts actions (*.do) with a response wrapping 
filter, so in WEB.XML I wrote :


   My Response Wrapper
   filters.WrapperFilter
 

   My Response Wrapper
   *.do

the code in my filter is  :

WrapperFilter.java
-
OutputStream out = response.getOutputStream();
out.write("PRE HTML FOR TEST ".getBytes());
GenericResponseWrapper wrapper = new GenericResponseWrapper 
((HttpServletResponse) response);
chain.doFilter(request, wrapper);
out.write(wrapper.getData());
out.write("POST HTML FOR TEST".getBytes());
out.close();
==

GenericResponseWrapper.java :
---
package filters;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletResponseWrapper;
import java.io.ByteArrayOutputStream;
import java.io.PrintWriter;
public class GenericResponseWrapper extends HttpServletResponseWrapper {
private ByteArrayOutputStream output;
private int contentLength;
private String contentType;
public GenericResponseWrapper(HttpServletResponse response) {
  super(response);
  output = new ByteArrayOutputStream();
  }
public byte[] getData() {
  return output.toByteArray();
  }
public ServletOutputStream getOutputStream() {
  return new FilterServletOutputStream(output);
  }
public void setContentLength(int length) {
  this.contentLength = length;
  super.setContentLength(length);
  }
public int getContentLength() {
  return contentLength;
  }
public void setContentType(String type) {
  this.contentType = type;
  super.setContentType(type);
  }
public String getContentType() {
  return contentType;
  }
public PrintWriter getWriter() {
  return new PrintWriter(getOutputStream(), true);
  }
}

when an action URL (http://localhost:8100/emgr/login.do) is called in 
browser,the page shows NOTHING ,that action is doing certain process and 
than forwarding to tile defininition : main.home.page ,  the logged error is 
:

jrun.servlet.io.ClosedIOException: Response has been closed
at jrun.servlet.io.ClosedOutputStream.write(ClosedOutputStream.java:23)
at java.io.BufferedOutputStream.write(BufferedOutputStream.java:109)
at jrun.servlet.http.WebOutputStream.write(WebOutputStream.java:64)
at java.io.OutputStream.write(OutputStream.java:58)
at filters.WrapperFilter.doFilter(WrapperFilter.java:176)
at jrun.servlet.FilterChain.doFilter(FilterChain.java:94)
at jrun.servlet.FilterChain.service(FilterChain.java:101)
   .
Also I noticed that the same filter is working fine if my action is 
forwarding to a JSP  instead of a tiles definition name
so instead of mapping the filter to *.do I mapped it to *.jsp :


   My Response Wrapper
   *.jsp

that time the page shows correctly with the pre/post text embedded.
I'm confused, is it a struts , tiles or JRUN problem ?
any help will be appreciated.

Regards.

RE: Compile Error for bean:define

[Carey Nation]

It _may_ be, and I'm just shooting in the dark here, that it's defined by
default someplace other than as a local variable (like in the request).  Try
adding scope="page" to the bean:define and see if that makes any difference.

HTH,
Carey

Re: Converting a ResultSet to a List of POJOs

[Kris Schneider]

So far, I think I prefer JSTL's Result interface for this type of operation:

import javax.servlet.jsp.jstl.sql.Result;
import javax.servlet.jsp.jstl.sql.ResultSupport;
...
ResultSet rs = ...;
Result result = ResultSupport.toResult(rs);
request.setAttribute("result", result);
...
Here's the javap on Result:

interface javax.servlet.jsp.jstl.sql.Result{
public abstract java.util.SortedMap[] getRows();
public abstract java.lang.Object[][] getRowsByIndex();
public abstract java.lang.String[] getColumnNames();
public abstract int getRowCount();
public abstract boolean isLimitedByMaxRows();
}
You can find more details in the JSTL spec in the SQL Actions section.

  List users = ses.createQuery("from u in class " + User.class

I've looked at the RowSetDynaClass (http://tinyurl.com/mekh), which has an
interesting way of doing this - is this the "recommended" approach in the
JDBC world?  Here's an example using it:
   ResultSet rs = stmt.executeQuery("SELECT ...");
   RowSetDynaClass rsdc = new RowSetDynaClass(rs);
   rs.close();
   stmt.close();
   ...;// Return connection to pool
   List rows = rsdc.getRows();
   ...;   // Process the rows as desired
Thanks,

SimpleMenuItem from TilesAction - NullPointerException

[Miguel Angel Martin]

Hello.

I'm trying access to Tiles context attributes from an 
TilesAction.   I've a definition where I put a list of 
SimpleMenuItems:
... 
 
   classtype="org.apache.struts.tiles.beans.SimpleMenuItem"/> 
...

In the execute method of the TilesAction

...
ArrayList lportlets = (ArrayList) 
context.getAttribute("portlets");
Iterator it = lportlets.iterator();
while( it.hasNext() )   {
 SimpleMenuItem plt = (SimpleMenuItem) it.next() ;
 
} 

Just in the last line (SimpleMenuItem plt = 
(SimpleMenuItem) it.next() ;) an 
java.lang.NullPointerException ocurs.   

But I write the value of it.next() before 
(System.out.println(it.next();) , I get
SimpleMenuItem[value=1, link=.portlet.noticias, 
tooltip=Noticias, ]

¿What's wrong?

Thank you.

Miguel Angel Martin.

Okay, gotcha.  At least it had a List.  LOL.

RE: Converting a ResultSet to a List of POJOs

[Micael]

I might as well go ahead and state boldly what I was trying to imply, 
Matt.  If you notice the CompositeEntity, then you can imagine altering 
that to include two changes to the norm.  First, you can make all the 
composite entities of the same type, and, second, you can change 
.getUserVO() to getVO(rs, object.class) pretty easily, right?  Or, do you 
want the entire thing to be done by reflection?  If not, tucking the SQL 
into the CompositeEntity might work for you.  No?

Si?

RE: Combining struts and JSTL tags...

[Loren Hall]

i haven't found a resolution to a problem previously posted under another
subject, since it fits this topic I thought
i'd put it out there again.

I started my app using struts tags, and recently incorporated jstl.

Unfortunately I get an error when I import both struts-bean.tld and c.tld

c.tld:   http://java.sun.com/jstl/core)
struts-bean.tld:
http://jakarta.apache.org/struts/tags-bean-1.0.2)

i.e. when these 2 taglib directives appear on a single .jsp

<%@ taglib uri="/WEB-INF/c.tld" prefix="c" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

i get the following exception:  jsp.error.tlv.invalid.page

null: org.xml.sax.SAXParseException: Attribute "xmlns:bean" was already
specified for element "jsp:root".

Converting a ResultSet to a List of POJOs

[Matt Raible]

Dear Struts Experts,

I recently started a new project where most of the backend code is already
written with JDBC and ResultSets.  The ResultSets are iterated through and a
POJOs values are set using pojo.setName(rs.getString("...")), etc. - you get
the point.  I'm wondering if there's an easier way - so I could do something
like this:

ResultSet rs = stmt.executeQuery("SELECT ...");
List objects = FancyUtilitity.convertResultSetToListOfObjects(rs,
object.class);

Hibernate let me do this very simply - and I miss the fact that I could type
a line or two to get a List of POJOs.  

  List users = ses.createQuery("from u in class " + User.class
   + "order by u.name").list();

I've looked at the RowSetDynaClass (http://tinyurl.com/mekh), which has an
interesting way of doing this - is this the "recommended" approach in the
JDBC world?  Here's an example using it:

   ResultSet rs = stmt.executeQuery("SELECT ...");
   RowSetDynaClass rsdc = new RowSetDynaClass(rs);
   rs.close();
   stmt.close();
   ...;// Return connection to pool
   List rows = rsdc.getRows();
   ...;   // Process the rows as desired


Thanks,

Matt

RE: how to start a background process using a struts action ?

[Michael Korolyov]

You may go with Quartz.
Where in your actions you just get user input and stores it (by Delegator / DAO) to 
Quartz table.

Or you can start / run new thread / class that has implemented Runnable interface.

That up to your business logic.

Best Regards.
Michael.

José,

This is really a system design question rather than a Struts
specific question so I've add the [OT] to the subject.  I've seen an
implementation similar to what you're asking about.  I'm not sure if
what I
can contribute will help you with your situation.  
Something to keep in mind is that you want to encapsulate the
different layers of your system from each other as much as possible.
You
want to use Struts to collect data and pass it to the lower layers of
your
system for processing, then return the results to the user.  You
wouldn't
want a Struts Action class doing business logic or Thread control etc.
[stepping off of the soap box]

Here's what you could do:

Process Definitions:  Create a DB table, xml doc, properties file,
whatever
that contains a definition of all the processes you'll need to running.
If
these are Java classes, this data could contain the fully qualified
class
name.

Process Request Queue:  Create a DB table, JMS queue or some other
persistence mechanism to queue up you process requests.

Front End:  Create your Struts front end to capture the request data and
persist it to your Process Request Queue.  

Daemon: Write a daemon class that polls your Process Request Queue and
runs
the requested process.  You can get as fancy with this as you want, you
could: multi-thread it, use a Strategy Pattern (GOF) to allow it to run
different process types, integrate email as an output distribution
mechanism, etc.  All the daemon really needs to know how to do is poll
your
Request Queue and when it sees a Request, run the appropriate process
based
on the Process Definition.  Obviously, each Request must have an ID back
to
a Process Definition along with any parameters that the process
requires.
You'd run this daemon in a separate JVM, not in Tomcat's.  For
performance
reasons, you may even run it on a different server than the one running
Tomcat.  If you executed your process in your Struts class you wouldn't
have
this option.

I hope this  at least gives you something to think about.

Thanks,

I had this problem when I pre-compiled my JSPs (Tomcat 4.1.24).

If I don't pre-compile then (from memory) they were encoded correctly. 
I am using tiles, so the layout page set the encoding to UTF-8, then 
everything else is included into the layout.  This might be why it 
worked, as the encoding was set on the parent JSP it was probably used 
when compiling the included pages.

When pre-compiling the JSPs each page is compiled separately.  In this 
case I think it used the default Latin encoding.

I couldn't find a way to forcethe compiler to use a different encoding 
other than adding <%@ page contentType="text/html; charset=UTF-8"%> to 
the top of every JSP page (including it didn't seem to work).

RE: Failing to get an answer,can it be done?

[Mike Jasnowski]

Are you sure the value isn't getting reset before it gets to your page? I
assume no exceptions are being thrown which prevent the field from
initializing, I saw earlier you're initializing this value in the
constructor.  What happens if you just leave the value assigned from the
private instance var and have the accessor retrive that w/o the stuff in the
constructor?

When you say "will I be able to get it", what do you mean? 

On your sample.jsp do you have the same form as on your original 
page? Or do you just need the value of select box item on the 
sample.jsp? If latter is the case you would have to attach the 
value to request context.

something like:
 request.setAttribute ("selectboxvalue", selBoxValue);

If first case is your case you would just need to declare name attribute 
in your action mapping element of struts-config.xml.

Date: Fri, 5 Sep 2003 08:53:49 -0400
MIME-Version: 1.0
Content-Type: text/plain; charset="iso-8859-1"

 Say I have a form "formFoo" which manages some noun "Foo".  It has
two different actions, "newFoo" and "editFoo".  Each has specific logic
depending on whether or not Foo exists.  I am experiencing a problem where
users create Foo, but then (either by bookmark or the back button) users are
returning to the "newFoo" action and edit Foo using the "new" action instead
of the "edit" action.

What about to create a custom tag which, if the newfoo already exists,
simply redirect the user to the editfoo form? In any case, take in account
that the 'Back' button issue is a known problem among web applications, and
that users should be aware of it.

My 2 cents,

Marco


I have looked into the transaction token to eliminate the double submit
problem, but I have not found a solution to this problem.  So far, I have
placed some assertions in the "newFoo" action which validates that foo does
not already exist.  If it does exist, it forwards control to "editFoo".

This brings about the design question.  Putting this kind of
assertion/redirection logic in each action class gets messy fast and makes
each action class more of a controller than an action class.  (Which is not
where I want to go)

Any suggestions on how to handle this type of problem?

Joshua

much faster that the 1.1b3 version, fewer bugs, and supported.
I do agree the error message

is very strange. 

So try the upgrade and lets go from there.

RE: How to click on a button to link to a page?

[Aleksandr Shneyderman]

you would need to create a mapping the for the sample.jsp suppose you call
it sample

in the action that will be processing your request when you ready to
redirect to sample.jsp just state
return mapping.findForward ("sample");

Unless I misunderstood again, but this is just a regular way to do the
redirection to the view component in struts.

RE: How to click on a button to link to a page?

[Rick Col]

Thanks,

Sorry, I did not make it clear. I actually need to
retrieve form data after I click go button. So,
basically, it has to go to action path specified in
struts-config.xml after clicking on the button. 

Can I simply replace "sample.jsp" with action path
specified in struts-config.xml in your code?

RE: Avoid Validate After Submit

[Kurt Post]

Here's how I do it in Struts 1.1.  I'm not sure how 1.1 is different from
1.01 in the validation area so your mileage may very.

First I have a base class for all my ActionForm's called ExtendedActionBase.
Among other things, this class defines some standard button name for "next",
"back", "cancel", and "OK" verbs.  The class will only perform validation if
a "next" or "OK" button was used to submit the form.  There's also some
extra junk in the class that has to do with accepting either simple  buttons.

The only other thing you need to do is on "back" and "cancel" buttons make
sure they are  buttons.  This insures that the JavaScript
validator will not validate the form.

I'll include ExtendedActionBase.java below.

Hope this helps,

Kurt

RE: Combining struts and JSTL tags...

[Siggelkow, Bill]

Basically, any of the struts tags that are "struts-aware" were not eliminated from 
Struts-EL -- specifically, the bean:message tag was not eliminated because it 
specifically looks in the application resources as specified in struts-config.  The 
 can be made to look into that bundle but it
does not by default the way the  tag does.  You might want to take a 
look at the 
my presentation http://www.jadecove.com/articles/jstl-and-struts.pdf to the Atlanta 
Struts User Group.

In addition, be sure and read the readme file in the contrib/struts-el folder.

RE: how to start a background process using a struts action ?

[Steve Hall]

José,

This is really a system design question rather than a Struts
specific question so I've add the [OT] to the subject.  I've seen an
implementation similar to what you're asking about.  I'm not sure if what I
can contribute will help you with your situation.  
Something to keep in mind is that you want to encapsulate the
different layers of your system from each other as much as possible.  You
want to use Struts to collect data and pass it to the lower layers of your
system for processing, then return the results to the user.  You wouldn't
want a Struts Action class doing business logic or Thread control etc.
[stepping off of the soap box]

Here's what you could do:

Process Definitions:  Create a DB table, xml doc, properties file, whatever
that contains a definition of all the processes you'll need to running.  If
these are Java classes, this data could contain the fully qualified class
name.

Process Request Queue:  Create a DB table, JMS queue or some other
persistence mechanism to queue up you process requests.

Front End:  Create your Struts front end to capture the request data and
persist it to your Process Request Queue.  

Daemon: Write a daemon class that polls your Process Request Queue and runs
the requested process.  You can get as fancy with this as you want, you
could: multi-thread it, use a Strategy Pattern (GOF) to allow it to run
different process types, integrate email as an output distribution
mechanism, etc.  All the daemon really needs to know how to do is poll your
Request Queue and when it sees a Request, run the appropriate process based
on the Process Definition.  Obviously, each Request must have an ID back to
a Process Definition along with any parameters that the process requires.
You'd run this daemon in a separate JVM, not in Tomcat's.  For performance
reasons, you may even run it on a different server than the one running
Tomcat.  If you executed your process in your Struts class you wouldn't have
this option.

I hope this  at least gives you something to think about.

Re: Syntax for accessing an object nested in a List of Lists [SOLVED]

Did you try list[index][index].property?

It is too late for me to test (1:34am - going to bed)

Robert Taylor wrote:
Okay. After looking at PropertyUtils I determined that this sort of syntax
is not allowed when accessing an object from an ArrayList of ArrayLists.
You have to wrap the child lists in an object which provides some type of
accessor/mutator. So in my case I have an ArrayList of ListWrapper objects.
Where each ListWrapper contains a List and getList()/setList(). Then the
syntax below
works - assuming my form bean has the methods getList()/setList().
list[index].list[index].property

Kind of a PIA to have to wrap the nested lists. Seems like PropertyUtils
would contain logic to recognize this use case but as I look at the source
code for getIndexedProperty, the necessary modifications would be none
trivial.

I've run into some trouble accessing a nested object in my form.
The object "lives" in a List of Lists type of structure.
I've been using a syntax like the following assuming my List form
property is named 'list'.
list[index].[index].productId

This must be wrong because I get the following exception:

No getter method available for property list[0].[0].productId for

I tried the following just to make sure it could find the 'first level'.

list[index]

This doesn't cause any exceptions, so I must have the syntax
wrong for accessing the 'second level' of the structure.
Any help would be appreciated?

Well, fancy scheduling API's aside, the action could launch a process via

The Struts web site recommends that you use JSTL instead of the bean and
logic taglibs. IMHO, all you need is JSTL and the html-el library, and you
can do anything that needs doing in a JSP page.

RE: issue with the multi select

[Mathew, Manoj]

I tried it and still form is not retaining the value

this is the select i declared in my jsp





there were another issue in the function which map the fields to the form

till date my dynaaction form were using just String.
so i got away with 
DynaClass dynaClass = form.getDynaClass();
DynaProperty[] props = dynaClass.getDynaProperties();
for (int i = 0; i < props.length; i++) {
Object propertyNameObj = props[i].getName();
String fieldValue = (String) form.get(propertyNameObj.toString()); 

But when i used string[] this was throwing ClassCast exception. and i couldn't find 
anyway to check if form.get(propertyNameObj.toString()) return a String or 
String[]..So i just put (String) form.get(propertyNameObj.toString()); in  a try/Catch 
block and in the catch block i checked for Classcast Exception and then i did
 String[] temp=(String[]) form.get(propertyNameObj.toString());.Assuming the 
classcast exception is thrown just because form.get(propertyNameObj.toString() 
returned a String Array..Bad  Programming..but couldn't find any other way to do 
that.)


Still i have issues..ie my Form is not retaining the multiselect box value..ie when 
any action in the same form post the form and comes back to the same page, i loose the 
data in the multi select box. i tried by selecting the values in the multi select 
box..but still not working...any ideas..?

You need to submit the changes in the field contents to the server. I
presume when you talk about the form being 'refreshed' you actually mean
that it POSTs to some action which does some stuff and then you get
forwarded back to the same jsp again?

The web browser will only submit the values for the _selected_ items in the
respective  fields. As far as the browser is concerned there are two
seperate select fields, and the values that are selected are only the ones
that are highlighted! (We know of course that its conceptually one field
with one box being unselected stuff and the other box the selected stuff,
but the browser isnt so smart)

What you need therefore is to ensure that the values are selected
(highlighted) at submit time.
This will involve some fancy javascript coding to go and set the 'selected'
property on all the option elements in both boxes when the form is
submitted.

(Before going ahead and spending time writing javascript to do this you will
probably want to confirm that this actually is the issue by manually
highlighting all the values in both boxes in your page, and invoking the
submit. See how it gets handled and what gets submitted in the request)


I HAVE DECLARED 2 STRINGS FOR THESE 2 SELECT BOXES


Surely you mean a string array ( String[] ) for each of the 2 fields as they
will both be submitting multiple values?

Hi all

  I have 2 multi select box( wth size 5)  and have  "ADD" and :remove"
button in a dyna action form. Basically you can select one or more from a
select box and add it to the second one using ADD buton adn remove the
selected using "REMOVE" button. I have some other actions also in the same
page.

issue:

   Add and REmove are working(in java script). but when he entire form is
refreched( when some other actions are executed), the select box is not
retaining the value.So basically "ADD" and"REMOVE" is not updating the form
values. I checked the valuew of the select boxes when the form is posted.
The values are not correct. ie it is not retaing my "ADD" and "REMOVE"
values..

IN STRUCTS_CONFIG, I HAVE DECLARED 2 STRINGS FOR THESE 2 SELECT BOXES

ADD
function add(value,to)
{ 
var newoption= new Option(value,value);
document.forms[0].s2.options[document.forms[0].s2.length]=newoption;

}
function remove(from) { 
for (var i=(from.options.length-1); i>=0; i--) { 
var o=from.options[i]; 
if (o.selected) { 
from.options[i] = null; 
   
} 
} 
from.selectedIndex = -1; 
}

how to start a background process using a struts action ?

[José Gustavo Zagato]

Hi Folks !

Does anyone here know if is possible to start a background
process ( like a daemon/service) using an action ? I need this feature
because the user will input a few parameters and a schedule date then
the system generate the user specific information.

Im using struts 1.1 and Toncat 4.1.18, so any tips on how can I
accomplish this task ?

I don't think there's an equivalent of the bean:message
tag in JSTL, if you want to continue using the
MessageResources mechanism.

So it's JSTL instead of bean and logic, except for
bean:message?

There is no Struts 1.1.3.  Your choices are 1.0, 1.0.1, 1.0.2, or 1.1 :-).
The quality of your JSP compiler is very important to the page rendering
times.  Struts is not the bottleneck in database driven webapps, the
database is.

[Siggelkow, Bill]

Pady -- generally, there is very little overlap between JSTL and the Struts HTML tags.
There are no JSTL tags that do the work that the Struts html tags do ... that being 
said, I 
encourage you to use the html-el library (basically the Struts html tags which support 
EL)
so you have the full power of EL for the HTML tags as well as the JSTL tags.

Good Luck!

Hey Yann Lebreton !

I have the same doubt as you, but for time constraints we decide
to use the encode at the JSP.

I have some questions about Internationalizations and maybe you
/ someone else could give me a more clear perspective on this subject...

I' am developing a site wich must run under several languages,
including Chinese, Thay, and many many others. I build several small
applications to prove that the location / I18N works fine on struts for
showing messages at the HTML. But My current concern is those input text
fields... How Can I handle the user Input ? I will save all entered data
in a Oracle database (already prepared to work with Unicode), but during
testing every time that I save some data in Unicode format the Database
don't understand it.

Does anyone here have any hint on this stuff ?

As part of localizing a site, I'm trying to set the content type of the

But I'd rather do this globally. I found out that you can set this as a
parameter of the controller in struts. This would work fine if the JSP
compiler wasn't also setting the content type automatically.

So do someone know a container setting to do this ? Is there something
like a "pre-compiler" for JSP, that would change/add code to each JSP
before giving it to the JSP compiler ?

RE: Probelm with routing.

[David Friedman]

Dear Sreekant,

When I programmed my RequestProcessor a about 2 weeks ago, I found
processRoles() throws exceptions which are absolutely not catchable by any
Exceptions listings in struts-config.xml.  So, I wrote better Java code to
catch things like null pointers.  Or (pardon the thick sarcasm), you could
try/catch it yourself in your method.  The reference to my filter is:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg78455.html
I did one typo, in step #3 i wrote 'scope='
when it should be 'roles=.'.

I've never had one login-related exception (null pointer or otherwise) since
the day I wrote the above RequestProcessor class, which I have in place and
test under every day.  The hard part for me was figuring out how to redirect
to the page of my choice, which you'll find in my example code.

Regards,
David

Installation problems on debian

[Volker Cordes]

Hi,

I'm using debian with Tomcat4. I copied all struts *.war-files into the
tomcat webapp-directory and they are listed in the manager. But running
the applications throws Exceptions like:
struts-example:
javax.servlet.ServletException: org/apache/jasper/runtime/JspException
at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:481)
root cause:
java.lang.NoClassDefFoundError: org/apache/jasper/runtime/JspException
at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:463)
struts-blank:
java.lang.NullPointerException
at org.apache.struts.util.RequestUtils.computeURL(RequestUtils.java:521)
In the logs there is the following entry (generated at tomcat startup):
org.apache.commons.digester.Digester getParser
SCHWERWIEGEND: Digester.getParser:
java.security.AccessControlException: access denied
(java.lang.RuntimePermission getClassLoader)
Thanks for any help,
Volker

RE: [OT] Character Encoding

[José Gustavo Zagato]

Hey Yann Lebreton !

I have the same doubt as you, but for time constraints we decide
to use the encode at the JSP.

I have some questions about Internationalizations and maybe you
/ someone else could give me a more clear perspective on this subject...

I' am developing a site wich must run under several languages,
including Chinese, Thay, and many many others. I build several small
applications to prove that the location / I18N works fine on struts for
showing messages at the HTML. But My current concern is those input text
fields... How Can I handle the user Input ? I will save all entered data
in a Oracle database (already prepared to work with Unicode), but during
testing every time that I save some data in Unicode format the Database
don't understand it.

Does anyone here have any hint on this stuff ?

Cheers !

As part of localizing a site, I'm trying to set the content type of the
response. Now I now I can do this within the JSP (<%@ page
contentType="text/html; charset=UTF-8" %> ). 
But I'd rather do this globally. I found out that you can set this as a
parameter of the controller in struts. This would work fine if the JSP
compiler wasn't also setting the content type automatically.

So do someone know a container setting to do this ? Is there something
like a "pre-compiler" for JSP, that would change/add code to each JSP
before giving it to the JSP compiler ?

Thanks,

Re: Validator cannot find message key

[Adam Hardy]

I see you're validating manually in the action. Have you tried doing it 
automatically with validate=true in the mapping?

I'm not saying you have to do it like that, but it should work that way. 
 You should specify the input attribute in the mapping as well.

Hi Saul,
to try to narrow this down a little, is the problem javascript or

One thing it might be is where you specified your
ApplicationResources.properties. It should be something like this in
struts-config.xml :
  
Perhaps it would help if we could see the relevant form-definition in

RE: debug level of struts...

[Pady Srinivasan]

This did not work for me also. And looking at ActionServlet code, I am not
even sure if this is used anywhere. Also this is deprecated.

Also Navjot had suggested to set

org.apache.struts = FINE  in jre/lib/logging.properties.

This didn't work. But when I set

java.util.logging.ConsoleHandler.level = FINE in jre/lib/logging.properties

I get all debug messages. But for this to work, make sure you are using 1.4
VM and don't have log4j in your classpath. Else you have to set the log4j
properties file for log levels.


Took some digging into Struts, commons-logging, JDK 1.4 logging source and
docs.

JBuilder seems to translate/compile every jsp in current project everytime

I wasn't aware there would be problems with actions.  That's just a matter 
of having a separate action href for each form.

While Tiles does work with Velocity, it seems to be redundant.   I migrated

Three questions

[Rouven Gehm]

Hi,

i'm new to Struts and have some minor questions which haven't been answered by Dr. 
Google, book or tutorial i've found and done so
far, so maybe someone here can give me a fast answer.
I've started working on a small application, where i nearly try to use everything 
Struts offers me,
tiles,nested,logic,...

1. How can i access the ApplicationResources.properties within an Action and/or 
ActionForm ?

2. For the LookupDispatchAction, can i only use Submit-Buttons with the keys like in 
the official documentation, or can i also use
a :link , but how do i set the key ?

3. I want to fill a tiles dynamically via a bean and tried to exchange this line

with this

and within the treeForm :
public String getActiveContent(){

return "/content/neu.jsp";

}

but it doesn't work. Have i misunderstood the use of tiles:put ???


Thanx in advance

How to set action in javascript.

[deepaksawdekar]

I am using the same jsp for create and modify techonolgy. Due to this i am facing some 
problems, like for that i need to set the action in the javascript. But for that i 
have to give the full path of action including base folder.  which i think its 
hardcoding, which i want to avoid. 

Is there any way i can do this. or some other way to get out of this problem.


What i am doing something like this,



function submitForm() {
 if (valAction == 'SUBMIT') {
Body.action="WebGUI/createTechnology.do";
}
if (valAction == 'UPDATE') {
Body.action="/WebGUI/updateTechnology.do";
}
}




Dir structure in tomcat is 

webapps
|_WebGUI
|_pages
|_web-inf.


Thanks and regards
Deepak.

[FRIDAY] Project Management

[Mark Galbreath]

A tourist walked into a pet shop and was looking at the animals on
display.

While he was there, another customer walked in and said to the
shopkeeper, "I'll have a C monkey please." The shopkeeper nodded, went
over to a cage at  the side of the  shop and took out a monkey. He fit
a collar and leash, handed it to the customer, saying, "That'll be
$5,000." The customer paid and walked out with his monkey. Startled,
the tourist went over to the shopkeeper and said, "That is a very
expensive monkey. Why did it cost so much?" The shopkeeper answered,
"Ah, that monkey can program in C - very fast, tight code, no bugs,
well worth the money."

The tourist looked at the monkey in another cage. "That one's even more
expensive! $10,000! What does it do?" "Oh, that one's a C++ monkey; it
can manage object-oriented programming, Visual C++, even some Java. All
the really useful stuff," said the shopkeeper.

The tourist looked around for a little longer and saw a third monkey in
a cage of it's own. The price tag around its neck read $50,000. He
gasped to the shopkeeper, "That one costs more than all the other put
together!

What  on earth does it do?" The shopkeeper replied, "Well, I haven't
actually seen  it do anything, but, the other monkeys call him the
Project Manager."

RE: Avoid Validate After Submit

[Pady Srinivasan]

I don't know if this works in 1.01 but I tried in 1.1.

You can use the HttpServletRequest passed into the validate method to find
out which button was pressed ( getParameter("Button2") ), and return an
empty ActionErrors.

Pady,

Your references are named "resumeInformation", but your action definition is
saving the form under the name "Resume".  Which are you using?  You might be
better off changing your action's name="Resume" to, perhaps,
name="resumeInformation".

RE: Syntax for accessing an object nested in a List of Lists [SOLVED]

[Robert Taylor]

Thanks for the reply Kris.

My problem wasn't really accessing the data on the page, it was
rather Struts accessing a property in an object buried in an ArrayList
of ArrayLists when the page was being rendered.

I was trying to keep my question as simple and to
the point as possible and therefore left out my actual intention.

The actual problem was using the erroneous syntax in an 





Which means the request parameter sent to the server was
"selectedProducts[0].[0].productId"

Well, when Struts tried to access the property (which it ultimately
delegated
to PropertyUtils) it was choking because there
was no getter for accessing the second ArrayList.

I described the work around in my follow up post.

Thanks again for the response.

Design Question - Need to put assertions in Actions?

[White, Joshua A (HTSC, CASD)]

Say I have a form "formFoo" which manages some noun "Foo".  It has
two different actions, "newFoo" and "editFoo".  Each has specific logic
depending on whether or not Foo exists.  I am experiencing a problem where
users create Foo, but then (either by bookmark or the back button) users are
returning to the "newFoo" action and edit Foo using the "new" action instead
of the "edit" action.  

I have looked into the transaction token to eliminate the double submit
problem, but I have not found a solution to this problem.  So far, I have
placed some assertions in the "newFoo" action which validates that foo does
not already exist.  If it does exist, it forwards control to "editFoo".

This brings about the design question.  Putting this kind of
assertion/redirection logic in each action class gets messy fast and makes
each action class more of a controller than an action class.  (Which is not
where I want to go)

Any suggestions on how to handle this type of problem? 

Regards,

Joshua

RE: Syntax for accessing an object nested in a List of Lists [SOLVED]

[Kris Schneider]

Robert,

Damn, I was just replying to your original note when you posted ;-). I'll
include my response below in case the "two-step" idea appeals to you:

Not sure if you've moved on from this, but I think you're either gonna have to
change the structure of your data or access it in multiple steps. Assuming you
can use JSTL and you want direct access (vs. looping) to the nested object at a
given index, I think you could do:




P.S.
I just checked and there's no Struts-EL version of ? Would've been
helpful here. One of the implications is that "index" has to be both a scripting
and scoped variable.

Re: debug level of struts...

[Peter Smith]

Hi Pady,

You might try adding this to your action servlet in web.xml:


  debug
  99


Let me know if this works for you,

RE: Syntax for accessing an object nested in a List of Lists [SOLVED]

[Robert Taylor]

Okay. After looking at PropertyUtils I determined that this sort of syntax
is not allowed when accessing an object from an ArrayList of ArrayLists.
You have to wrap the child lists in an object which provides some type of
accessor/mutator. So in my case I have an ArrayList of ListWrapper objects.
Where each ListWrapper contains a List and getList()/setList(). Then the
syntax below
works - assuming my form bean has the methods getList()/setList().

list[index].list[index].property


Kind of a PIA to have to wrap the nested lists. Seems like PropertyUtils
would contain logic to recognize this use case but as I look at the source
code for getIndexedProperty, the necessary modifications would be none
trivial.

debug level of struts...

[Pady Srinivasan]

Is there a way to make Struts print out more messages to standard out ? Like
when it loads the form-bean and resets form values into the jsp ?

Thanks

RE: How to reference multiple form beans from one VelocityLayoutS ervlet set of page fragments?

[Edgar P Dollin]

I have gotten two html:forms two work in a limited fashion with struts.
Note that your always visible form, doesn't have to be connected with a
struts action so the problems with actions wouldn't apply.  Also, the rules
for forms are different if you are using tiles since each tile has an action
and I believe tiles works with Velocity.

Reference to how multiple forms may not work with Velocity:


http://www.mail-archive.com/[EMAIL PROTECTED]/msg06945.html

Contrary reference that it might be possible to reference "multiple forms" 
with $form in Velocity:


http://www.mail-archive.com/[EMAIL PROTECTED]/msg05261.html


Probably unimportant details:

I'm using Struts 1.1, Tomcat 4.1.27, the Validator, and the 
VelocityLayoutServlet from Velocity-tools-1.0.  I've got my layout broken 
out into the generic standard:

layout
header
menu
body
footer

I've got a form that is generally visible in the menu section. I have
arbitrary forms that can appear in the body section, and these I plan 
to pass by the action mapping.
I'm using org.apache.struts.validator.DynaValidatorForm for all Form Beans.

Thanks!

-Mike
