Hello,
I have a problem since a while and I am not sure about the source of the
problem. I will use the sample application to explain it here (I will call
my project gwt_tmp):
1 - I create a default gwt sample project with GPE.
2 - I start a debug session with the default Jetty Dev Mode.
A - I run application in my browser in dev mode, it loads corretly.
B - In the sample application, I enter an user name and click the button
that will execute an RPC call to the server
C - GPE (I suppose) detects that a call is done to an RPC service, and
generates the XXXX.gwt.rpc policy file.
D - I receive a response, all is fine.
Perfect! Now, I stop the server and clean the generated directory under
war/gwt_tmp to be sure to start from a clean environment.
I want to execute the same process but with tomcat instead of Jetty to
reflect my real production environment:
I update some configurations files to add a web tool nature to my project :
1 - I add a new nature to my .project under eclipse :
<nature>org.eclipse.wst.common.project.facet.core.nature</nature>
2 - I creates associated settings files :
* /gwt_tmp/.settings/org.eclipse.wst.common.component
<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId" project-version="1.5.0">
<wb-module deploy-name="gwt_tmp">
<wb-resource deploy-path="/" source-path="war"/>
<wb-resource deploy-path="/WEB-INF/classes" source-path="/src"/>
<property name="java-output-path"/>
<property name="context-root" value="gwt_tmp"/>
</wb-module>
</project-modules>
* /gwt_tmp/.settings/org.eclipse.wst.common.project.facet.core.xml
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<fixed facet="jst.web"/>
<fixed facet="jst.java"/>
<installed facet="jst.java" version="6.0"/>
<installed facet="jst.web" version="2.5"/>
<installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>
3 - I update my gwt application launcher to not run in server mode (since
tomcat will be the server).
4 - I start the dev mode of the application, and I start tomcat.
A - I run application in my browser in dev mode, it loads corretly (but on
port 8080 for tomcat instead of 8888 for jetty)
B - In the sample application, I enter an user name and click the button
that will execute an RPC call to the server
C - GPE (I suppose) detects that a call is done to an RPC service, and
generates the XXXX.gwt.rpc policy file.
D - Here is the problem ! Tomcat does not seams to realize that a new file
has been generated on disk. the log says :
INFO: greetServlet: ERROR: The serialization policy file
'/gwt_tmp/1CC4B1A5D8B73AD7482A23834A893A1B.gwt.rpc' was not found; did you
forget to include it in this deployment?
GRAVE: greetServlet: WARNING: Failed to get the SerializationPolicy
'1CC4B1A5D8B73AD7482A23834A893A1B' for module '
http://127.0.0.1:8080/gwt_tmp/gwt_tmp/'; a legacy, 1.3.3 compatible,
serialization policy will be used. You may experience
SerializationExceptions as a result.
If i refresh my workspace and I restart tomcat, it reload correctly the
previously generated .rpc file and I no longer get this error.
I tried to activate the auto refresh of worspace file in my eclipse
configuration, but it did not resolved this.
I know that the worspace auto refresh is not implemented in the same way
between windows and linux (
https://bugs.eclipse.org/bugs/show_bug.cgi?id=108697)
Since gpe sources are not available, I wanted to be sure that GPE developers
have requested a workspace localRefresh on XXX.gwt.rpc generated file (
http://wiki.eclipse.org/FAQ_When_should_I_use_refreshLocal%3F)
I might be completly wrong about this, but I have no other idea.
Maybe someone has already met this problem and found a solution ?
Thanks,
Nicolas ANTONIAZZI
