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.
