Re: embeddedJsp plugin causing jsp compilation issues
Hi Musachy,
There's another classloading conflict issue with the embedded jsp plugin.
This one has to do with the ELContextImpl.
Loading an embedded jsp page that uses EL and then trying to load a normal
page that uses EL throws:
java.lang.ClassCastException:
org.apache.struts2.jasper.el.ELContextImpl cannot be cast to
org.apache.jasper.el.ELContextImpl
at
org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(PageContextImpl.java:920)
Again, the embedded jsp page seems to cache it's version of the
ELContextImpl ( ion PageContextImpl.proprietaryEvaluate) which tomcat then
tries to cast to it's own version.
It looks like I could simply stop PageContextImpl from storing it's
generated EL context by modifying the getELContext() method, but I'm
guessing on a page/application with a lot of expressions that could hurt
quite a bit.

Re: embeddedJsp plugin causing jsp compilation issues
Posted by Musachy Barroso <mu...@gmail.com>.
I commited a fix (aka hack), and it seems to work in both tomcat and
jetty. basically, in JspFactory if the servlet passed as a param is
not one that the embedded jsp plugin created, then I delegate the call
to jasper's JspFactory. Let me know if it works.
