The source of the problem seem to come from the fact that the proxy site
URL is different from the GWT app URL. This is discussed and nicely
documented in
https://groups.google.com/forum/?fromgroups#!searchin/google-web-toolkit/proxypass$20serialization/google-web-toolkit/3wE9yWLMJo4/Mebd0XgW1EIJ
(thanks
to the authors for this!)
The following proxy setting works properly as the URL are the same:
Location /openmetadata-www-user-gwt/
ProxyPass ajp://localhost:9009/openmetadata-www-user-gwt/
/Location
In my case, I can rename the underlying GWT app on tomcat so that should
solved the issue. The post above provide excellent alternate solutions.

I'm trying to proxy a GWT app running on my local Tomcat server through
Apache use AJP but am getting 500 errors during RPC calls.
I simply have a standard entry in my httpd.conf file:
Location /user/
ProxyPass ajp://localhost:9009/openmetadata-www-user-gwt/
/Location
When I run the app directly on
http://localhost:9090/openmetadata-www-user-gwt/ I have no problem, but
when I go through the proxy, I can see the RPC call go through but then
getting serialization errors while returning objects:
SEVERE: Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type
'org.openmetadata.www.user.client.UserServiceException' was not assignable
to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a
custom field serializer.For security purposes, this type will not be
serialized.: instance =
org.openmetadata.www.user.client.UserServiceException: User not found
Tried with http proxy (and on standard ports) but same issue. Seem like an
RPC serialization policy problem but not sure what to do. Any suggestion
would be appreciated.
