I've tried with <bean:write... but since I catch exception saying MyActionForm can't be found in any scope. As far as I'm aware I've set request scope like:
<action input="/jsp/something.jsp" name="MyActionForm" path="/jsp/myAction" scope="request" type="sth.MyAction">
<forward name="success" path="/jsp/index.jsp"/>
<forward name="failure" path="/jsp/something.jsp"/>
</action>

Send message from JSP page to Java message driven bean

Hi all
I'm using Jdev903.
I need to send a message from JSP page (Web Application) to Java Message Driven Bean.
* I created Message Driven Bean that named: MyMessageDrivenEJBBean
* I have configed jms.xml:
<topic-connection-factory name="ChatTopicConnectionFactory" location="jms/theTopicConnectionFactory"/>
<topic name="ChatTopic" location="jms/theTopic"/>
* In JSP page, my code is:
final Context ctx = new InitialContext();
// 1: Lookup ConnectionFactory via JNDI
TopicConnectionFactory factory =(TopicConnectionFactory)ctx.lookup("jms/theTopicConnectionFactory");
But trouble occurs is:
javax.naming.NameNotFoundException: jms/theTopicConnectionFactory not found
please help me!
thank a lot.

Welcome to the Sun forums.
1. Please post your code using code tags, this formats it so that it is easier for people to read and understand it. Click on 'CODE' above the text area when posting.
2. As far as possible, please post an SSCCE
What have learnt about JSPs and servlets till now? Because reading the values submitted in a form is pretty much the base of all operations. I suggest you Google for [servlet tutorials|http://www.google.com/search?q=servlet+tutorial] and [JSP tutorials|http://www.google.com/search?q=jsp+tutorial] and go through them thoroughly. After you understand what is to be done and what options are available to you, if you still face problems, please feel free to post your queries here. But this isn't exactly a site for tutorials, especially since there are so many good ones already out there, that explain all this stuff in detail. There's no point in re-inventing the wheel.

Using EL variable in struts bean:message tag(not struts EL tag)

Is there any work around to use an EL variable inside struts bean:message tag as key:
I have like this:
<bean:message key="${bean.keyName}"/>
which is throwing error , I know this can be resolved by using struts-el tags but i cannot use them for specific reasons.
I dont want to use bean:define tag to define my 'bean' and then use like this:
<bean:message key="<%=bean.getKeyName%>"/> (this actually works, but i want to use EL variable)
Is there any work around to use EL variable and make the message display on the jsp.
i tried multiple ways like scriplets and jsp:useBean but nothing worked, Please let me know..
Thanks in advance

Im pretty sure that EL does not work in the normal struts tag unless its struts-el tag.Have you tried it?
As I said, in a properly configured JSP2.0 container you can use EL expressions anywhere you could traditionally use a standard runtime expression <%= expr %>.
What server are you using? What JSP version?
The Struts-el tags were written so that you could use EL with struts in JSP1.2 containers.
The c_rt tags were written so you could use runtime expressions with JSTL tags in JSP1.2 containers. Their use was discouraged even then. Now I consider their use absolutely unnecessary.

Using a heirachical key name in bean:message

This is sort of an odd requirement but it will help me out greatly if I can find a way to do this.
I am working on creating a JSP which generates vxml. I am using a resource properties file to read in text that I need to speak, or the names of wave files that I need to play. I grab these using a bean:message tag lib call. This all works fine but now I need to extend this app to handle several different States (Kentucky, Ohio, etc) which may or may not have small variations in their verbiage.
Tell me if I am going about this entirely wrong but this is what I think would be nice to do:
I would like to use the name of the key in this form:
"prompt.company.state"
Where an example resource properties file might be like this:
mainmenu.columbia.ky=mainmenu_ky.wav
mainmenu.columbia=MM_Columbia.wav
mainmenu=mainmenu.wavWhat I would like to happen is if I request the key "mainmenu.columbia.ky" it returns the "mainmenu_ky.wav", but if I request "mainmenu.columbia.oh" it would return "MM_Columbia.wav"
The idea is that a company may operate in different states and customize its prompts for that state if custom prompts exist but if they do not exist it uses the default for that company. Also there could be different company names also so if I asked for "mainmenu.northface" I would receive "mainmenu.wav"
This is sort of like localization but I want to have all the keys in one file.
My thought is that I would need to create my own taglib that extends bean:message and then parses the key name accordingly until I find a matching key. My problem is I have no idea where to start when doing that. I am while I have a strong Java background its been almost 4 years since I've worked on a project using it, and all this Struts and JSP and JSTL stuff is quite new to me.
Does anyone have any tips for me? Maybe there is another tag lib out there which does exactly what I need and I just don't see it. Help anyone?

Struts bean:message encoding help

Hello, i am using Struts framework and have problems with resource files.
I have two files for english and lithuanian.
jsp file:
<%@ page contentType="text/html; charset=Cp1257" pageEncoding="Cp1257"%>
Developed by: <bean:message key="developer.name"/>
So its echo bad string.
Any ideas?

I have had same problem but I have resolve it by both changing the encoding property of IDE(mine is NetBeans 3.6) to UTF-8 and
put the line
<%@page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8" %>on the top of jsp pages.
But now I having some problems with formbean I hope I resolve it.
You can follow it from here

Storing bean:message value

I want to be able to utilize a request.getParameter value to make the key attribute for the bean:message to be dynamic. I have parts of my application urls in the ApplicationProperties.properties and I want a parameter to dynamically tell bean:message which key to use. Then once bean:message pulls back that data, I want to store it into a field to use in an jsp:include. Can this be done?
I pretty much would like to do the following if it was legal syntax:
<jsp:include flush="true" page="bean:message key="<%= request.getParameter(pageType) %>""/>

It is possible if u use JSTL-RT tag not the JSTL-EL tag. Please check
http://java.sun.com/webservices/docs/1.0/tutorial/doc/JSTL.html

bean:message/ tag is not working in tiles:insertAttribute/

I have a bean:message tag inside my tiles:insertAttribute as shown below.
<tiles:insertAttribute name='<bean:message="user.menu"/>'/>But <bean:message/> is not getting the value from resource bundle, my resource bundle is in correct place. If i hard code the value then it s working fine.
How to make it work? Any help?

sunish_jose wrote:
<tiles:insertAttribute><bean:message="user.menu"/></tiles:insertAttribute>this way it s not working. Could you pls tell how solve it by using EL. I was not able to find a similar sample evenafter searching for some time.
thanks in advance.I did say that I don't know if it will or not, I was just giving a sample of how it would work if the tag allowed the value for 'name' to be put in the body.
I'm not very familiar with the Struts bean tags and in any case, I believe you should use the JSTL tags where ever possible. So you'd pick the <fmt:message> tag from there. I don't think the <bean:message> tag allows you to get the value in to a variable.
<fmt:message var="tilesAttributeNameValue" key="user.menu" />
//create an EL variable named tilesAttributeNameValue with the value from the resource bundle
<tiles:insertAttribute name="${tilesAttributeNameValue}"></tiles:insertAttribute>
//use EL to put the valueTake a look here [1] for a JSTL introduction:

Hi beattris,
No I dont close the rs and conn objects.
The relevant method of my bean is :
public void processQuery() throws Exception{
     try{
          Class.forName(getDrivername());
          conn = DriverManager.getConnection(getUrl(),getUsername(),getPassword());
          st = conn.createStatement();
          rs = st.executeQuery(getQuery());

BEAN : Bean included in JSP Page

Hi ,
I had developed a web-application in that I had included a bean in a JSP code by using the following
<jsp:useBean id="testbean" scope="session" class="path.test" />
now the problem is some times when we click on that particular JSP page where this bean is included the screen instead of generating the jsp page it gives a complete path of the bean location as specified in the JSP ( i.e ) "path.test" .
When I click the refresh button then the page get's loaded properly.
This issue taken place rarely but it's very important to solve this and it happens in all the JSP pages wherever I had included a bean but only sometimes .
Why so??? and help me to solve this problem
Server: Apache � Tomcat 5.0
thanks in advance

You are absolutely correct. All your java classes should be in packages.
I actually think its a java limitation introduced in Java 1.4 - they no longer allow access to the unnamed package.
For full details check out: http://developer.java.sun.com/developer/bugParade/bugs/4361575.html
My suggestion: include all your beans in packages. Its not that hard is it?

Two managed beans in same jsp page

Hello
First this could be a stupid question, but i just can't find a solutions on this problem.
I wondering that could it be a two managed beans in same jsp page, here is a example:
index.jsp
<t:commandLink disabled="#{listBean.currentPage == 1}" id="previous2" type="button" immediate="true" style="font-size:small" action="#{listBean.previousPage}">
<h:outputText value="Edellinen" id="prev"/>
</t:commandLink>
<t:commandLink disabled="#{listBean.currentPage == listBean.totalPages}" id="next2" type="button" immediate="true" style="font-size:small;" action="#{listBean.nextPage}">
<h:outputText value="Seuraava" id="next"/>
</t:commandLink>
then i have a dataTable like this:
<t:dataTable value="#{customerListBean.customerBeans}"
binding="#{customerListBean.dataTable}" preserveDataModel="true" style="text-align:left">
My problem is that when i push a commandLink it doesn't refresh a dataTable. Does anyone know a solution here or is this just a impossible way to do it?
Thanks for help.

when i push nextPage (commandLink) it's call action
and count a new range of dataset and after that it's
calls a method which is declared on subClass and that
method get a new data of database on given params.
and put it on DataTable.
So listBean is upper class and customerListBean
extends on ListBeanNo, it doesn't work that way as you expected. You have created two independent instances. They doesn't communicate automatically with each other or so. Just use one CustomerListBean instance and call the inherited methods of ListBean on the #{customerListBean} managed bean instance.

How to call the form bean value on jsp withthe help of jstl tag

hi
all friends
i am working in struts & i use jstl tag in jsp. i have one problem rise is how to call the form bean value in jsp page by using jstl tag.
i now how to retrive the value through jsp:logic
eg. <logic:empty name="userListForm" property="users">
NO USER FOUND
</logic:empty>
see * userListForm mean formbaen name.
* users means collection object.
so how can i write above e.g in jstl

You use the jstl core:if or core:choose combined with the EL:
<c:if test="${empty users.userListForm}">
NO USERS FOUND
</c:if>I suggest you lookup the jsp expression language (EL) using google, it's very powerful.
