Jboss4.2 with Eclipse 3.3 - Page does not refresh

[Tauri Valor]

Hi

Im using Jboss4.2 in Eclipse3.3 for my development. When I try to refresh my page it doesnt refresh. Even after restarting the server and restarting the machine, there was the same old page thats appearing.

I get the same error message even after clearing the error.

The reason I thought is that , Eclipse is storing the old Ear file in some location after the first build and it is using the same forever without recreating the new one.


Please help me on this.

Thanks in advance.

Tauri.

Did you try flushing the browser's cache? Most of the time this does it for me.

Also, to completely clean out the server, stop the server and remove the server/xxx/data, server/xxx/log, server/xxx/work and server/xxx/tmp directories.

Peter, Thanks for responding.

Yeah I did flush out my cache and deleted data,log and work from my Jboss. It did not work.

Is there any way that we can write a Context xml file as we do in tomcat to manually describe the Project location and build location ?

Thanks.

To define an alternate deployment location, edit the URLlist attribute in the last mbean in the server/xxx/conf/jboss-service.xml file.

Hi Tauri!

You should look at this article on the JBoss Wiki: JBoss Wiki: Using context.xml

Alas, I suspect that it will not help you much. You could check the settings for the JSP servlet to see if the "checkInterval" has been set to a to high value.
Check the file (assuming your using the "default" server) JBOSS_HOME/server/default/deploy/jboss-web.deployer/META-INF/web.xml

Look at the comments there to find appropiate settings for your system. For production systems it is recommended to turn of JSP file checking as it will increase performance, but for development that would make the server useless.

Hi Thanks again.

I have the following parameters for my jsp servlet.

Theres no check interval param specified in the configuration, so I assume its '0' by default.

Please let me know if Im missing out anything.

 <servlet>
        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>fork</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>xpoweredBy</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
         <param-name>compilerSourceVM</param-name>
         <param-value>1.5</param-value>
        </init-param>
        <!-- Use a custom options class to allow the shared tag lib descriptors
         to be loaded from jars in the tomcat sar conf/tlds directory. The
         standard options implementation can only find taglibs based on the
         class loader classpath.
        -->
        <init-param>
           <param-name>engineOptionsClass</param-name>
           <param-value>org.jboss.web.tomcat.service.jasper.JspServletOptions</param-value>
        </init-param>
        <!-- Specify the jars relative to the jbossweb-tomcat6.sar that should
          be scanned for common tag lib descriptors to include in every war
          deployment.
        -->
        <init-param>
           <description>JSF standard tlds</description>
           <param-name>tagLibJar0</param-name>
           <param-value>jsf-libs/jsf-impl.jar</param-value>
        </init-param>
        <init-param>
           <description>JSTL standard tlds</description>
           <param-name>tagLibJar1</param-name>
           <param-value>jstl.jar</param-value>
        </init-param>
 
        <load-on-startup>3</load-on-startup>
    </servlet>

You could try settting the "development" to true and "modificationTestInterval" to 0. Setting it to 0 means that the JSP will be recompiled every time it is being accessed.

Ex:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
...
<init-param>
<param-name>development</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>modificationTestInterval</param-name>
<param-value>0</param-value>
</init-param>
...
</servlet>

Note: I have previously spent a lot of time figuring out why JBoss doesn't show changes to my JSP only to find out that I'm checking out the wrong URL.

You can also find set the "keepgenerated" attribute on the jsp servlet to true to check the be able to see the java classes generated by the JSP compiler. Check the Tomcat Jasper How-to for more information regarding configuring the Jasper/JSP servlet.
