Hello,
I'm currently facing an issue while upgrading to gwt 2.2.
My application uses spring on server side, and gwt dispatch for
communication.
Strack trace is
SEVERE: Exception while dispatching incoming RPC call
java.lang.NullPointerException
at javax.servlet.GenericServlet.getServletName(GenericServlet.java:
238)
at javax.servlet.GenericServlet.log(GenericServlet.java:204)
at
com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:
211)
at
com.google.gwt.user.server.rpc.RemoteServiceServlet.processPost(RemoteServiceServlet.java:
243)
at
com.google.gwt.user.server.rpc.AbstractRemoteServiceServlet.doPost(AbstractRemoteServiceServlet.java:
62)
at
it.miriade.planner.server.service.BaseRemoteService.handleRequest(BaseRemoteService.java:
25)
etc.
This issue (I faced it in the past) is due to new compilation of GWT
modules, and subsequent variation in serialization policy files, which
make the old rpc service incompatible with the new compiled module.
I noticed that GWT 2.2 compiles some files under WEB-INF/deploy/
which look related to serialization policy, and so to this bug. What I
need to know is how this output folder can be configured, and if
there's a workaround to make the policy files easily accessible
(taking them out of WEB-INF if this is not an issue). Or maybe if this
incompatibility is due to other issues.
Thanks to everyone
Lorenzo
