Jsp and Debug option

[roberto]

How can i set the "-g" and keepgenerated options during JSP compilation ?

For example using Weblogic i can set this options in the web.xml as context-param like this...

<context-param>
<param-name>weblogic.jsp.keepgenerated</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>weblogic.jsp.compileOptions</param-name>
<param-value>-g</param-value>
</context-param>


Thank You

If you are using Jetty, ensure that you have a recent JBoss3 release and look in the .../deploy/jbossweb.sar/webdefault.xml file.

This controls default settings for all webapps, including how Jasper is mapped.What you need is probably available as a init-param on Jasper.

If you figure it out, post an explanatory paragraph and I will put it in my Jetty/JBoss FAQ

I found the solution.

You have right... i must use the webdefault.xml,
but i must use JBOSS 3.0.4 (using JBOSS 3.0.3 i have some problem)

under \deploy\jbossweb.sar modify the webdefault.xml as below
