I've put in some more effort to get Struts 2.1.8 snapshot running in
live GAE environment. I made progress moving to Sitemesh 2.4.2,
disabling OgnlRuntime SecurityManager and moving to convention-2.1.8-
SNAPSHOT (WW-3114)
The next issue is that XWorks XMLConfigurationProvider throws a
SecurityException on the following line (211):
// Force loading of class to detect no class def found exceptions
cimpl.getDeclaredConstructors();
SecurityException: Unable to get members for
o.a.s.c.PackageBasedActionConfigBuilder
cimpl is the Class of the ActionConfigBuilder bean specified in struts-
plugin.xml and loaded by ClassLoaderTools. I believe this is a
technique to eagerly load the class.
I'm not sure why that's access is not permitted in the sandbox. It's
not documented anywhere I can see and It only occurs in the live
environment.
As a work-around (guess), I changed it to cimpl.getDeclaredClasses()
instead which is permitted (I don't know if this has the same effect
on the ClassLoader). That got me past the issue above, but the same
SecurityException occurs in XWork's ContainerImpl
$ConstructorInjector.findConstructorIn():
SecurityException: Unable to get members for Class
o.a.s.v.v.VelocityManager
which seems to be a fundamental problem with XWork's constructor
injection in GAE.
As a side note, Guice 2's constructor injection works okay in GAE. I
imagine the Guice 2 codebase is now very different beast than XWork's
IOC though.
I guess I need to approach the GAE forum now. Has anyone got any
ideas about what to attempt next on the S2/Xwork side? Stack traces
for the two cases are below.
regards,
Jeromy Evans
