Hi,
I using weblogic 6.0 sp1 and struts to develop the web application, I deployed
my web application by war file,I want precompile jsp when weblogic server starts
up by defining the following context parameter in web.xml deployment descriptor:
<context-param>
<param-name>weblogic.jsp.precompile</param-name>
<param-value>true</param-value>
</context-param>
but it failure to pre-compiling JSP's when weblogic server start. I visited
weblogic newsgroup, and followed the info to try using directory struct to deploy
(under .\config\mydomain\applications
or outside of the .\applications directory), both of them had errors. the following
is my web.xml file and error info. Could you give some idea to fix it?

Thanks

Judy
