WebsphereTestEnvironment problem

[wessel zaalberg]

I try to get the MVC pattern working in the IBM VAwebsphereTestEnvironment. I works just fine with tomcat.
However the WTE is configured in a different way. An application a .webapp type of file.
In the defailt_app.webapp file I have included :
-----------------------------------
<servlet>
<name>action</name>
<description>Action class lader</description>
<code>ActionServlet</code>
<servlet-path>/</servlet-path>
<init-parameter>
<name>action-mappings</name>
<value>actions</value>
</init-parameter>
<autostart>false</autostart>
</servlet>
<servlet-mapping>
<name>action</name>
<description>Zoek de juiste beanclass</description>
<url-pattern>*.do</url-pattern>
<servlet-path>/action</servlet-path>
</servlet-mapping>
<taglib>
<taglib-uri>/jsp/demoAmmsys/utilities</taglib-uri>
<taglib-location>/jsp/demoAmmsys/tlds/utilities.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/jsp/demoAmmsys/application-tags</taglib-uri>
<taglib-location>/jsp/demoAmmsys/tlds/app.tld</taglib-location>
</taglib>
-------------------------------------------
The problem is it is loaded immediately on the start of the servlet engine. It should be called only when a request is done with a .do extention.
What do I have to do : first to stop it from being loaded on startup and second to have it called only when a request is send?

Hi
Please change the servlet path to /xxxx instead of /.
This may serve ur purpose.
Give a try. All the best for the same.

Thanks.
I did and now I get a very strange error : in the console:
Error: Cannot get the local host address.
Exception: Connection refused: no further information
on the page :
Error 500
An error has occured while processing request:http://localhost:8080/demoAmmsys_app/stam_gegevens.jsp
Message: Server caught unhandled exception from servlet [jsp]: null
In the trace :
java.lang.NullPointerException
java.lang.Throwable()
java.lang.Exception()
java.lang.RuntimeException()
java.lang.NullPointerException()
void com.ibm.ivj.jsp.debugger.base.JspEMAgentBase.openServerSocket()
void com.ibm.ivj.jsp.debugger.base.JspEMAgentBase.openServerSocket()
I compile in v1.1

Hi,
Looks like some code in the jsp is throwing a NullPointerException. Just check up your jsp and initialize all variables so that this excepion will not be thrown.

Actually it has everything to do with
<.code>com.ibm.ivj.jsp.jasper.runtime.JspDebugServlet</code.>
It is missing something while compiling.
If I choose to use
<.code>com.ibm.ivj.jsp.runtime.JspDebugServlet</code.>
(inserted . in < .code> for readebility)
all is well accept I need in the code
< .%@ taglib uri='utilities' prefix='util' %.>
In the tld is written:
<?xml version="1.0" encoding="ISO-8859-1" ?>
< !DOCTYPE taglib PUBLIC <br /> "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN" <br /> "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
<.taglib>
<.tlibversion>1.0</tlibversion.>
<.jspversion>1.1</jspversion.>
<.shortname>Sun Microsystems Press Examples</shortname.>
So it seems the jsp version 1.1 is required.
And that doesnot compile.

The exception I get is thrown in openServerSocket of com.ibm.ivj.jsp.debugger.JspEMAgentBase.
Error in debug failed to write (toString() failed) later it becomes null pointer.
On the console is written :
Error: Cannot get the local host address.
Exception: Connection refused: no further information
Please, this is the chance to show yourself a super guru ;-)

I am not sure if you are using Struts. If yes, try to modify your defailt_app.webapp file as follows:
-----------------------------------
<.servlet>
<.name>action<./name>
<.description>Action class loader<./description>
<.code>org.apache.struts.action.ActionServlet<./code>
<.servlet-path>/<./servlet-path>
<.init-parameter>
<.name>application<./name>
<.value>com.ibm.mag.gui.ApplicationResources<./value>
<.name>config<./name>
<.value>/WEB-INF/struts-config.xml<./value>
<.name>action-mappings<./name>
<.value>actions<./value>
<./init-parameter>
<.autostart>false<./autostart>
<./servlet>

thanks, but I am not using struts.
I eventually solved the problem by doing a compleet new install and started from a clean repository.
I had to add to the actionservlet an url path *.do so that it was not dealt with by the simpleFileservlet.
