Re[2]: no struts classes (jar files) found by application
Hello Michael, *** MK Hello Dirk, MK thanks for your answer. MK That means that I end up with tons of redundant struts packages on my MK production machines and many redundantdantdant class loading processes MK on server startup. Oh well, hard to digest ... MK BTW, do you know by any chance whether this applies to the velocity MK packages and to the commons libraries too? Bill in an earlier mail gives you the link to a document describing the problem in more detail. I don't know whether velocity can be put into the shared directory, but I doubt and wouldn't advise. MK It seems that struts also requires that all the libraries that it MK depends on are located in the WEB-INF/lib diretory as well. MK Is that also right? MK Greetings MK Michael Kastner MK Dirk Markert schrieb: Hello Michael, *** MK Hello, MK maybe someone can help. I've tried to deploy two struts applications to MK two tomcat test servers (one running tomcat 5.0 and one running tomcat MK 4.1) but I can't get it to work on neither of them. MK For development purposes I had all required jar files in the MK application's WEB-INF lib. Then I've removed them all and deployed my MK war files to the servers.

Message Resource lookup curiosity..
Caroline Jen's question make me think about something. I'm wondering how other people deal with this particular issue- Say that you have some sort of i18n'd app, and on a JSP screen for doing CRUD, you have one or more select boxes. You use html:option tags that get the labels (and maybe even the values) out of the correct Message Resource properties file. This gets whatever you need saved into the database that way in any language you support. Great. No problem. But - later on some display screen: You have retrieved the value that had been previously of the select box. You want to display the corresponding label with a bean:message tag. It's in the properties file after all. So, how do you go about getting the key for the corresponding label to display? How do you go about divining the key to use to get it out of your MessageResource file? I mean, if you can't do that, why bother using the properties file for this in the first place? The solution would be more obvious if html:options or html:optionsCollection supported a key attribute (how it would be supposed to work is another good question!). I see the following ways to go about it. 1) A database lookup for value-MessageResources key, preferably into some collection in application scope at startup. 2) making the values themselves the MessageResources keys (Gag. Choke. Wheeze.) 3) Some sort of call to MessageResources or MessageBundle, or an extension to said classes. hand waving occurs Option 1 seems to be the most palatable if there's a way to do it without needing to change the code with every message resource addition.

Re: tiles sidebar,header,footer
There is an example of this in the struts example code. What you are asking to do is kind of the whole reason for using Tiles (or at least a fairly important one), so I can assume you really haven't looked at any of the user documentation/examples as of yet. I'd suggest a visit to http://jakarta.apache.org/struts/ and reading through the documentation.

Re: Message Resource lookup curiosity..
This will depends on your design strategy.
Say Message.properties is:
form.gender.male=Male
form.gender.female=Female
and you are storing the key form.gender.male into the database.
So,
you need to write a simple class Commons.java that contains:
public final static String getMsg(MessageResources msgRes, Locale
locale, String key)
{
String msg = ;
try
{
msg = msgRes.getMessage(locale, key);
}
catch (Exception e)
{
System.out.println(Error in getting message. + e.toString());
}
return msg;
}
In your Action class:
form.setGender(Commons.getMsg(this.getResources(request),
this.getLocale(request), form.gender.male));
of course you need to retrieve the form.gender.male key from the database
as a String attribute.
So to display the value in your jsp page:
bean:write name=myForm property=gender scope=request filter=true/
The property gender is a property in your detail and form object.

preventing user from validating twice
Hi, i think it must be a FAQ, but i did not found anything on this issue. When my user submits a form, the action executes an SQL Insert in the DBMS. What happened is that when user click twice, the second inserts fails with SQLException. What is strange, is that i cannot reproduce it in WSAD, but it happens on a full Websphere. Is there a way i can know that a user already submitted a form ? = Olivier Citeau Paris, France Créez gratuitement votre Yahoo! Mail avec 100 Mo de stockage ! Créez votre Yahoo!

RE: preventing user from validating twice
You can use savetoken(request) method for generating a token (when loading the
screen)and
Cheque for the existence of token using istokenvalid(request) method for ensuring that
you do not submit same data again.
Code in action wld be like
isTokenValid(request)
{
...
DB insert
}

Problem with Apache and Tomcat integration
Hi! I'm having problems with Apache+Tomcat integration. I've configured Apache to listen on port 7001 and Tomcat on 8080. The struts-example application works fine, but whenever I call an Action in my own application , the URL is changed to port 8080 when that Action finishes (using return(mapping.findForward(myforward))). Every request that goes thru servlet changes URL port to 8080. I've compared my forward and action definitions in struts-config.xml with the struts-example ones, and they seem identical. I've also compared both web.xml files. Does anyone know where the problem can be? Sorry, I don't post any configuration files here because I have no idea of which file is causing that behaviour. I think the Apache-Tomcat connection is set up properly, because as I said, the example application is working. Thanks in advance.

Re: [OT] load testing
This is application/context dependent. Ebay users may have a wait time of 2-20 seconds, where the low end results from scanning a page and dismissing it out of hand and the high end is the result of an auction with a REALLY long/detailed/funny description. Other web applications may have incredibly complex pages that result in a user parking on that page for 60-6000 seconds. What I suggest is that you convene a group of representative users (could be internal analysts and/or QA members) and record their use sessions. A little statstical analysis on the wait times should provide you with enough data to confidently randomize wait times.

RE: [OT] load testing
I don't know the answer to your specific question, as I think it involves some industrial strength statistical math. But ... I'll tell you what we did. Our application needed to be load tested to ensure performance within certain times at up to 50 users. (We actually tested to 100 users, just for grins ... load testing is fun :-) We created a functional test using HttpUnit and JUnit to represent our primary usecase. Ours is a control system and this usecase was time critical, while the other usecases were deemed not time critical, so we just load tested with the one usecase. Then, using JUnitPerf, by the wonderful and talented Mike Clark (http://www.clarkware.com/), we drove the test at up to 100 simultaneous users, each running a number of the functional tests back to back (25 to 50 times per simulated user). This created a worse case load test (think slashdot effect :-). Personally, I liked this, as I wanted to know when the application would run out out of steam. Obviously this test is unrealistic, but it did give us plenty of confidence that we could handle anything that was expected to be thrown at us. So, in your situation, I would create functional tests that represented the most common and most time critical usecases for your system. Then open the flood gates and send a tidal wave of traffic against the system. I'm sure that realistically simulated usage is wonderful, but for the rest of us, just hammer the system until it begs for mercy and then you'll know what it can take. :-) Simon -Original Message- From: Nicolas De Loof [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 23, 2004 7:57 AM To: Struts Users Mailing List Subject: [OT] load testing Hi all, I've to make some load tests on my app. Our customer wants the appli to handle 300 simultaneous users.

Validation errors are still errors and are still stored in request scope using the key org.apache.struts.Globals.ERROR_KEY (which has the literal value org.apache.struts.action.ERROR) This is the default location where the html:errors and html:messages tags both look for an ActionMessages object. More generally: the difference between the classes ActionErrors/ActionError/ActionMessages/ActionMessage has *absolutely nothing* to do with the difference in behavior in Action.saveErrors(...) and Action.saveMessages(...) The difference between the classes is zero -- all behavior in ActionErrors was pushed up into ActionMessages and all behavior in ActionError was pushed up into ActionMessage. This was done in the attempt to clearly signal that these classes can be used to pass any kind of messages from the controller to the view -- errors being only one kind of message. The difference between saveErrors(...) and saveMessages(...) is simply the attribute name under which the ActionMessages object is stored, providing two convenient default locations for storing controller messages for use by the view. If you look more closely at the html:errors and html:messages tags, you can actually use them to get an ActionMessages object from any arbitrary attribute name in any scope. While we're clarifying, the difference between html:errors and html:messages is purely in syntax and model -- both tags *default* to look for an ActionMessages object under Globals.ERROR_KEY despite the difference in names. I wasn't part of the history, but I'm assuming that around the same time that people were realizing that there's more than one kind of message to pass, they also realized that sometimes you want more flexibility in displaying them. html:messages provides more flexibility at the cost of more typing. I hope this helps to clarify things. I would strongly encourage people to have a look inside the Struts source code, as it's really quite clear when you look under the hood. You can see what happens in validation by examining the processValidate method in RequestProcessor: http://cvs.apache.org/viewcvs.cgi/jakarta-struts/src/share/org/apache/struts/action/RequestProcessor.java?view=markup You can see what happens with saveErrors and saveMessages by examining those methods in Action http://cvs.apache.org/viewcvs.cgi/jakarta-struts/src/share/org/apache/struts/action/Action.java?view=markup You can see what the tags do by looking at their respective source files: http://cvs.apache.org/viewcvs.cgi/jakarta-struts/src/share/org/apache/struts/taglib/html/MessagesTag.java?view=markup http://cvs.apache.org/viewcvs.cgi/jakarta-struts/src/share/org/apache/struts/taglib/html/ErrorsTag.java?view=markup I'll put most of this text in the Struts Wiki at http://wiki.apache.org/struts/ActionErrorsAndActionMessages Anyone who wants to clarify is encouraged to document it there, and, of course, if you see a place in the core struts docs that could make this more clear, we welcome documentation contributions as much as code contributions.

RE: How to use dynamically generated CSS style with Struts tags
I don't at present use any taglibs whatsoever in the app I'm doing this in,
so I don't know if there is any added complexity involved there. But as far
as what I AM doing goes, I'm not sure what will really be helpful, so let me
get as detailed as I can and you can ignore the superfolous parts...
First, the application I'm doing this in allows users to set their own color
scheme, font scheme, and some other style elements (within a defined set of
things they can possibly change). So, I have a UserScheme table with
columns like BackgroundColor, FontSize, TextColor, etc.
So, in each JSP I have the line:
link rel=StyleSheet href=/app/styles.act type=text/css
This is mapped to an Action called StylesAction. All it does is reads in
all the columns from the above table for the current user. I then dump all
those values into a HashMap (I simply key it off the column name in the
table).
Next, in the styles.jsp, I do things like this:
% HashMap styleData = (HashMap)request.get(styleData); %
.cssMainBody {
background-color : %=(String)styleData.get(backgroundColor)%;
color : %=(String)styleData.get(textColor)%;
font-family : %=(String)styleData.get(fontFamily)%;
font-size : %=(String)styleData.get(fontSize)%;
font-weight : %=(String)styleData.get(fontWeight)%;
}
...and so on. Then, I just use those style classes in my other JSP's like
I would any other style tag (I always do className=xxx where xxx is the
classname like cssMainBody above).
That's all there is to it. Without knowing more about the taglibs your
using I can't really say if this will work as-is or not, but it certainly
works were taglibs are not involved. Hope that helps!

Re: New Validating system instructions?
Joe,
There have been some subtle changes especially within the Validator, for
example the xml you no longer specify arg0-arg3, you specify an arg then
give it a position attribute to change message key info for display.
A couple things I've had to do that seem pretty tedious and could likely be
a target of some good refactoring. I've done previous development where I
stored all errors in an ActionErrors object under its default key in the
session, however having to put html code into my properties file was not
something I wanted to do on my new app. So what I do now is store
everything in ActionMessages, and I store messags/errors under different
property values within that object. So when I go to display errors my jsps
look something like:
logic-el:messagesPresent message=true property=GLOBAL_ERROR
h4 class=RedErrors:/h4
ul style=margin-top: 0; margin-bottom: 0;
html-el:messages id=error message=true property=GLOBAL_ERROR
lic:out value=${error}/
/html-el:messages
/ul
/logic-el:messagesPresent
or GLOBAL_MESSAGE for messages. However this was a significant challenge to
accomplish. Since the commons-validator seems to store errors under random
properties within the ActionErrors object I needed to put this into my
validate method of ValidatorActionForm:
ActionErrors validatorErrors = super.validate(mapping, request);
ActionErrors errors = new ActionErrors();
if (validatorErrors != null) {
for (Iterator i = validatorErrors.get(); i.hasNext();) {
ActionMessage message = (ActionMessage)i.next();
errors.add(Globals.GLOBAL_ERROR, message);
}
}
Note my use of Globals.GLOBAL_ERROR is my own set of Globals within the app.
Is there somewhere I can specifically tell commons-validator what property
to store errors it finds under? I couldnt find it but it may exist.
Secondly I did have to overwrite the processValidate method of my request
processor to store the results of the validate() method into session scope
under the Messages key instead of Errors.
Quite a bit of work just to get messages to show up it seems :)
Thoughts/Comments?
Oh and on a sort of related rant, within the xml commons validator why in
the world can you not substitute in runtime values? IE if I am validating
an email address I want to do something like:
{0} is not a valid email address
and within that {0} substitute in the value the user submitted, all within
the xml.
So something like
arg value=emailAddress position=0 runTimeValue=true/

Julia: I think your question may not be too clear. First what do you mean by delete a record in struts? Strictly speaking, I believe Struts does not (should not) have code which properly belongs the business/database layer. So assuming that you want to show a confirmation page when your application successfully deletes a record in the database, all you have to do is forward the user to a success.jsp. Which is similar to what you always do in Struts. So what exactly is your problem? If you explain your problem more and/or show some code, maybe someone can help you out.

RE: How to use dynamically generated CSS style with Struts tags
Thank you Frank,
I understand how you use it, the strings you've generated can then be used inside the
Struts tags (inline generation). by giving values to the style and styleClass
attributes inside the tag)...

Subject: RE: How to use dynamically generated CSS style with Struts tags
I don't at present use any taglibs whatsoever in the app I'm doing this in,
so I don't know if there is any added complexity involved there. But as far
as what I AM doing goes, I'm not sure what will really be helpful, so let me
get as detailed as I can and you can ignore the superfolous parts...
First, the application I'm doing this in allows users to set their own color
scheme, font scheme, and some other style elements (within a defined set of
things they can possibly change). So, I have a UserScheme table with
columns like BackgroundColor, FontSize, TextColor, etc.
So, in each JSP I have the line:
link rel=StyleSheet href=/app/styles.act type=text/css
This is mapped to an Action called StylesAction. All it does is reads in
all the columns from the above table for the current user. I then dump all
those values into a HashMap (I simply key it off the column name in the
table).
Next, in the styles.jsp, I do things like this:
% HashMap styleData = (HashMap)request.get(styleData); %
.cssMainBody {
background-color : %=(String)styleData.get(backgroundColor)%;
color : %=(String)styleData.get(textColor)%;
font-family : %=(String)styleData.get(fontFamily)%;
font-size : %=(String)styleData.get(fontSize)%;
font-weight : %=(String)styleData.get(fontWeight)%;
}
...and so on. Then, I just use those style classes in my other JSP's like
I would any other style tag (I always do className=xxx where xxx is the
classname like cssMainBody above).
That's all there is to it. Without knowing more about the taglibs your
using I can't really say if this will work as-is or not, but it certainly
works were taglibs are not involved. Hope that helps!

Hi,
you can use the JSTL1.1 (or 1.0 as you want) in the following way:
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
table
c:forEach items=${requestScope.pageRecords} var=row
trc:out value=${row.Id}//tr
/c:forEach
/table
you can use pageScope, requestScope, sessionScope or
applicationScope depending on the pageRecords is stored.

UserDetail detail = (UserDetail)iter.next();

pageRecords is a Collection of UserDetail object.
UserDetail is my data transfer object.
I can manage to get the expected result of detail.getId()
How can I represent the above code in logic:iterate tags ?
The following code doesn't work.

RE: How to use dynamically generated CSS style with Struts tags
For resources that make good candidates for caching, like images and CSS files,
it's worth looking at using a servlet that overrides getLastModified.
Obligatory JSTL plug:
%@ page contentType=text/css %
%@ taglib prefix=c uri=http://java.sun.com/jstl/core; %
.cssMainBody {
background-color : c:out value=${styleData.backgroundColor}/;
color : c:out value=${styleData.textColor}/;
font-family : c:out value=${styleData.fontFamily}/;
font-size : c:out value=${styleData.fontSize}/;
font-weight : c:out value=${styleData.fontWeight}/;
}
Even better with JSP2.0:
%@ page contentType=text/css %
.cssMainBody {
background-color : ${styleData.backgroundColor};
color : ${styleData.textColor};
font-family : ${styleData.fontFamily};
font-size : ${styleData.fontSize};
font-weight : ${styleData.fontWeight};
}

RE: delete a record
This is not a struts issue. You have a few choices. JavaScript is a poor one, in my opinion. Use two response objects: one to give them the option and the second to give them the option the second time. Another way to do this is to archive the record instead of deleting it and only delete it upon confirmation. You can archive the record by creating a boolean archive value in the record. There are lots of solutions, of course.

Which does not work. Should i be using EL syntax
instead? And what would the correct syntax be?
I did check that c:out value=${contentId}/ returns
a valid value so my confusion is just passing it as a
value to the html:hidden property.
Any help is greatly appreciated.

LabelValueBeans
Is there anyway to have a property in my ActionForm class be defined as follows: private LabelValueBean[] myItems; And be able to have struts automatically populate this collection when the form is submitted? If so, how do I go about storing those values in the form so they're seen and populated properly upon submission? Thanks! Chris
Re: Setting html:hidden property using JSTL
I've also noticed you are doubling up on double quotes, try this:
html:hidden property=contentId value=c:out value='${contentId}'//
or
html:hidden property=contentId value='c:out value=${contentId}/'/

Do you include the HTML tag library within the jsp page? It needs to go
at the top and look like this:
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html %

R: Setting html:hidden property using JSTL
Hi,
yes you can use the EL but depends on the Web Container you are using.
If you have a Web container JSP2.0 (and 2.4 servlet) compliant (for
example Tomcat5.0.x), you can use JSTL 1.1 (if you want to use them you
have to set your application)and html Struts standard.
In order to use, this version you have to do the following in the jsp
page:
%@ taglib uri=http://jakarta.apache.org/struts/tags-html;
prefix=html%
html:hidden property=contentId value=${contentId}/
But if you have a WebContainer JSP1.2 compliant (e.g. Tomcat 4.x) you
have to use the html-el version + JSTL1.0. They are in the contrib
directory inside the struts directory. But in this case the procedure in
order to use them is just to complicate.

Use the html-el tag instead of the html tag. Then you can do:
html-el:hidden property=contentId value=${contentId}/
Much cleaner.
Although remember it might even be easier/cleaner to simply make sure
contentId is in your ActionForm .. then you can just do...
html:hidden property=contentId/ and it'll set the value for you.

Struts and PL/SQL
Hi all! I´ve been using Struts a lot with EJB and Hibernate with no problems. But I always wondered if it´s possible to use an architecture that uses STRUTS and goes directly to PL/SQL for the database layer. I know it is possible in many way, but I would like to know if there is any special product or package that integrates with PL ( the only one I found is http://portalstudio.oracle.com/servlet/page?_pageid=473_dad=ops_schema=OPSTUDIO ) ... any pointers?

How to read a large XML file in the ActionServlet
Hi
I want to read a a large XML file for each request that comes to the
ActionServlet.
This is for a reporting application. What I did was I created seperate XML
file where I have specified the action elements and its related subelements.
So when I get the request I get the corresponding XML node from the XML file
for that action and based on its subelements I enter a log into a database.
So I have my customized ActionServlet. And I am instantiating myXmlClass in
the process method. And I call a method called
myXmlClassObject.getXMLLogMessage() for each request (for each Action
class).
What is the recommended way to do this.
The problem that I am having is that the application freezes at the line
instantiate myXmlClass in the process method of my servlet.
Currently my code look like this
//MyActionServlet.java
init()
{
//perform initialization()
super.init()
}
process()
{
//do stuff
instantiate myXmlClass (which has a _saxparser.parse() method)
myXmlClassObject.getXMLLogMessage()//some database calls underneath it for
some logging
//do stuff
}
Should I make a static object of myXmlClass in my actionServlet.
Should I put myXmlClass into session, and check for each request whether
this object exists in session, if not create it.
Please help!!

RE: How to read a large XML file in the ActionServlet
I don't care how good of an XML parser you are using, parsing virtually any
XML file on a per-request basis is a Bad Idea (tm). You definitely want to
find a way to (a) store the parsed information in memory, or (b) maybe read
it from a database, which may or may not actually wind up being any better
depending on numerous factors.
I used to have to use a custom framework here at work before my glorious
leaders finally decided to listen to us architects an use Struts. This
framework used XML profile database, much like struts-config.xml. Early
on, this thing was reading this file for EVERY request, just to determine
which controller element to execute and where to forward to afterwards.
Apps built on this thing were just barely OK on killer hardware. Well, the
very first week I was using the thing, I rewrote the preprocessor that
parsed this file and instead read it in once at app startup and then read
the data in memory. True, there was no longer a way to do real-time profile
changes without downing the app, but all of a sudden our apps were flying
like nobody's business, and server load decreased for the same number of
concurrent users by a HUGE factor. Needless to say, people were rather
happy.
I can't stress the point enough: parsing XML per-request is almost never a
good idea. Making your myXmlClass class static (well, the result of the XML
parsing static anyway) is one way to go, and might be the best way,
performance-wise. Do the parsing from a Struts plug-in, store it in a
HashMap or whatever you need it to be in that class as a static member, and
your problem will probably go away.

This will depends on your design strategy.
Say Message.properties is:
form.gender.male=Male
form.gender.female=Female
and you are storing the key form.gender.male into the database.
So,
you need to write a simple class Commons.java that contains:
public final static String getMsg(MessageResources
msgRes, Locale locale, String key)
{
String msg = ;
try
{
msg = msgRes.getMessage(locale, key);
}
catch (Exception e)
{
System.out.println(Error in getting message. +
e.toString());
}
return msg;
}
In your Action class:
form.setGender(Commons.getMsg(this.getResources(request),
this.getLocale(request), form.gender.male));
of course you need to retrieve the form.gender.male key
from the database as a String attribute.
So to display the value in your jsp page:
bean:write name=myForm property=gender scope=request
filter=true/
The property gender is a property in your detail and form object.

Subject: Message Resource lookup curiosity..
Caroline Jen's question make me think about something. I'm
wondering
how other people deal with this particular issue-
Say that you have some sort of i18n'd app, and on a JSP screen for
doing CRUD, you have one or more select boxes. You use html:option
tags that get the labels (and maybe even the values) out of the
correct Message Resource properties file. This gets
whatever you need
saved into the database that way in any language you
support. Great.
No problem.
But - later on some display screen:
You have retrieved the value that had been previously of the select
box. You want to display the corresponding label with a
bean:message
tag. It's in the properties file after all.
So, how do you go about getting the key for the
corresponding label to
display? How do you go about divining the key to use to get
it out of
your MessageResource file? I mean, if you can't do that, why bother
using the properties file for this in the first place?
The solution would be more obvious if html:options or
html:optionsCollection supported a key attribute (how it would be
supposed to work is another good question!).
I see the following ways to go about it.
1) A database lookup for value-MessageResources key,
preferably into
some collection in application scope at startup.
2) making the values themselves the MessageResources keys
(Gag. Choke.
Wheeze.)
3) Some sort of call to MessageResources or MessageBundle, or an
extension to said classes. hand waving occurs
Option 1 seems to be the most palatable if there's a way to do it
without needing to change the code with every message resource
addition. Maybe #3 resulting in #1.
Anyone got an approach they like?

RE: Struts and PL/SQL
If your trying to avoid the overhead of EJB, then you may want to look into the Spring framework. I've been wanting to find a flexible architecture/framework which allows me to start with a non-EJB type of approach and easily scale to using an EJB container while minimizing the impact on the application. This article may provide some insight: http://www.theserverside.com/articles/printfriendly.tss?l=SpringFramework I would still advise wrapping your dataccess code in a business delegate or application service instead of binding your Struts Action to the business logic implementation. robert -Original Message- From: Lucas Gonzalez [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 23, 2004 2:07 PM To: Struts Users Mailing List Subject: Struts and PL/SQL Hi all!

RE: How to read a large XML file in the ActionServlet
Thank you very much for your suggestions, Frank. That was really helpful.

Date: Wed, 23 Jun 2004 14:30:27 -0400
I don't care how good of an XML parser you are using, parsing virtually any
XML file on a per-request basis is a Bad Idea (tm). You definitely want to
find a way to (a) store the parsed information in memory, or (b) maybe read
it from a database, which may or may not actually wind up being any better
depending on numerous factors.
I used to have to use a custom framework here at work before my glorious
leaders finally decided to listen to us architects an use Struts. This
framework used XML profile database, much like struts-config.xml. Early
on, this thing was reading this file for EVERY request, just to determine
which controller element to execute and where to forward to afterwards.
Apps built on this thing were just barely OK on killer hardware. Well, the
very first week I was using the thing, I rewrote the preprocessor that
parsed this file and instead read it in once at app startup and then read
the data in memory. True, there was no longer a way to do real-time
profile changes without downing the app, but all of a sudden our apps were
flying like nobody's business, and server load decreased for the same
number of concurrent users by a HUGE factor. Needless to say, people were
rather happy.
I can't stress the point enough: parsing XML per-request is almost never a
good idea. Making your myXmlClass class static (well, the result of the
XML parsing static anyway) is one way to go, and might be the best way,
performance-wise. Do the parsing from a Struts plug-in, store it in a
HashMap or whatever you need it to be in that class as a static member, and
your problem will probably go away.

Subject: How to read a large XML file in the ActionServlet
Date: Wed, 23 Jun 2004 14:15:08 -0400
Hi
I want to read a a large XML file for each request that comes to the
ActionServlet.
This is for a reporting application. What I did was I created seperate XML
file where I have specified the action elements and its related
subelements. So when I get the request I get the corresponding XML node
from the XML file for that action and based on its subelements I enter a
log into a database.
So I have my customized ActionServlet. And I am instantiating myXmlClass
in the process method. And I call a method called
myXmlClassObject.getXMLLogMessage() for each request (for each Action
class).
What is the recommended way to do this.
The problem that I am having is that the application freezes at the line
instantiate myXmlClass in the process method of my servlet.
Currently my code look like this
//MyActionServlet.java
init()
{
//perform initialization()
super.init()
}
process()
{
//do stuff
instantiate myXmlClass (which has a _saxparser.parse() method)
myXmlClassObject.getXMLLogMessage()//some database calls underneath it for
some logging
//do stuff
}
Should I make a static object of myXmlClass in my actionServlet.
Should I put myXmlClass into session, and check for each request whether
this object exists in session, if not create it.
Please help!!

Not sure. If you have

- proper definition of the tld in web.xml
- proper declaration for the tld on top of the page
then using it as:
html-el:hidden property=contentId value=${contentId}/
should be fine.
The only thing I'm still concerned about and maybe somehow it's related
is that contentId has to be a property of your ActionForm or else Struts
would complain that it couldn't find the property 'contentId' Are you
maybe creating the contentId var dynamically first in the JSP page and
then trying to set as above? Usually you don't need to do like you are
doing (setting the value) since that value can be set before you get to
the page and thus just doing html:hidden property=contentId would be
fine.
What does c:out value=${contentId}/ produce on the page (or in

Getting index value of iteration
I have been pouring over all the posts and how-tos I can find on indexed properties and indexed values in general, and I am just not getting it. Here is what I am trying to do: I have a search page in a section of my main jsp. It returns results into a SELECT, and the chosen item in the SELECT populates it's corresponding property in the related Form. In another section of the page I display an iterated list of items in a collection. In each row that is rendered, I have a text input control, and a button next to it. When the user clicks on the button, the idea is to have the selected result from the search populate the text input control. I call a method in the related Action class to retrieve the selected search result, and then I need to put it into the correct detail item. THere is a property in the detail item corresponding to the text input control. So I would like to do somthing like collection[i].setDestIndex(srchForm.getSelText); but I am stuck on how to get the value of i, the index of the row wherein the button was clicked. I have tried setting up the iterate tag as: nested:iterate id=index property=costs . nested:text property=destIndex indexed=true / There is an index property in the Form, and in the item class that is a member of the collection being iterated over. I cannot seem to catch the index property anywhere, either as a property in struts or as request.getParameter(index). I am sure this is easy THanks for any ideas you can float my way, and please use small words to match my minimal intellect g T.

form so they're seen and populated properly upon submission?
Well, a LabelValueBean has two string properties -- how would you
automatically populate even a single instance, let alone an array?
Or are you suggesting that the form presents the user with a series
of paired input fields, essentially label1, value1, label2,
value2, etc?
If so, you could essentially do it by exposing an indexed property,
labelValueBeans and then arranging to have your request parameters
be named as such:
labelValueBeans[0].label
labelValueBeans[0].value
labelValueBeans[1].label
labelValueBeans[1].value
I would do this using c:forEach and the struts-el tags, roughly like this:
c:forEach begin=0 end=5 varStatus=status
Label: html:text property=labelValueBeans[${status.count}].label /br /
Value: html:text property=labelValueBeans[${status.count}].value /br /
/c:forEach
If you aren't using the EL, there are other ways to do this, but
frankly, I never learned how to do them and I think it's cleaner with
the JSTL.

Validator maxlength, minlength
In essence, maxlength and minlength are working backwords from what I would expect.
I fully expect this to pebcak error, but I can't seem to find it.
I'm getting :
Address 1 can not be greater than 30 characters.
Address 2 can not be greater than 30 characters.
City can not be greater than 30 characters.
When address 1 is 27 characters, address 2 is blank and city is 10.
Clearly I've fat fingered something somewhere.
Can anyone help me figure out why maxlength is acting like minlength?
btw minlength also works backwards.
Validation file looks like:
...
constant
constant-nameaddressLength/constant-name
constant-value30/constant-value
/constant
constant
constant-namecityLength/constant-name
constant-value30/constant-value
/constant
...
field property=address1 depends=required, maxlength
arg0 key=ChangeAddressForm.address1 /
arg1 name=maxlength key=${var:addressLength} resource=false /
var
var-nameaddressLength/var-name
var-value${addressLength}/var-value
/var
/field
field property=address2 depends=maxlength
arg0 key=ChangeAddressForm.address2 /
arg1 name=maxlength key=${var:addressLength} resource=false /
var
var-nameaddressLength/var-name
var-value${addressLength}/var-value
/var
/field
field property=city depends=required,maxlength
arg0 key=ChangeAddressForm.city /
arg1 name=maxlength key=${var:cityLength} resource=false /
var
var-namecityLength/var-name
var-value${cityLength}/var-value
/var
/field
...
and the form:
...
private String address1 = null;
private String address2 = null;
private String city = null;
...
appropriate getters setters etc.

Re: How to pass parameters to forward in bean:include?
Did you try using the 'page' attribute and just adding the values manually to the query string? Robert Bowen wrote: I would like to do a bean:include id = forward= ... / ... but looking at the Struts API, something I cannot do is pass the forward parameters. If it were an struts html link tag I could do: html:link forward= paramId= paramName= ... / ... thus calling the forward with parameters. Can I not do this with the forward used in my bean:include? How the heck can I pass parameters to a forward in a bean include then? Any help much appreciated. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Struts - How to recover collection element
I've loaded a collection of valid options and their descriptions as a ServletContext attribute, for use in an html:options tag. It works as intended in a generated html select tag. Once a user selects an option, the option value (rather than the description) is recorded in a form bean, and the form bean is forwarded to another form. So far so good. What I'd like to do in the next form is display the description of the selected option, using the option as a lookup key to the original collection. Is there an existing struts tag that will allow me to do this? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Struts - How to recover collection element
There are a couple of ways of doing this. I think the best approach is
to wrap your collection in a JavaBean that is stored in the session.
Something like the following:
public class OptionsHolder {
Map options = new HashMap();
public OptionsHolder() {
options.put(key1, new LabelValueBean(foo,key1));
options.put(key2, new LabelValueBean(foo,key1));
}
public Collection getOptionsCollection() {
return options.values();
}
public Map getOptionsMap() {
return options;
}
}
You can then use the getOptionsCollection() method to render the options
in the first form. Then in the page where you want to display the value
for the key, you can use JSTL. Assuming the ServletContext attribute
name were optionsHolder and the key was in the property 'key' on the form:
c:out value=${optionsHolder.optionsMap[MyForm.key]}/
Another alternative is to create a mapped property in the OptionsHolder
bean; then use Struts support for mapped properties in the bean:write tag.
Finally, a third alternative would be to fetch the value in the action
that processes the form. Extract the desired value then set it as a
request attribute for display on the subsequent JSP. With this approach
you might not need to use the OptionsHolder class and instead just
iterate over the collection looking for a match.

How to execute an initialization by using another servlet entry in web.xml
Can somebody provide some sample code to do this. Please look at this link http://nagoya.apache.org/wiki/apachewiki.cgi?StrutsInitialization. I want to use #3 approach mentioned in this link. My questions are : (A stupid question) Does this initialization class that I would specify in web.xml, should it be a servlet,ActionServlet, or most importantly could it be a just an ordinary java class. How do I access this servlet entry(this instance of class) from my main ActionServlet?

generators for struts
hi i am starting a new project which involves struts and i am completely new to it. The IDE i am familar with is Netbeans. What tool does fellow developers used for struts? I downloaded struts console but looks like it allow me to edit/manage struts configuration file in netbeans only. Is there any xdoclet like tool that make code generation easiler? If possible please provide plugin/tool for netbeans instead of eclipse. I can't find a plugin for running jboss in netbeans too. Any references?
