GWT 1.4 deployment to JBoss fails when making RPC call

[nijoblue]

I have tried many combinations to deploy the packaged war file to
jboss 4.0.4 and each time I get this error when making an RPC call.
The xxxxx.gwt.rpc file is definitely packaged in the war file. The
client launches fine. gwt-servlet.jar file is in WEB-INF/lib and
web.xml is updated with the servlet mapping.

Anyone else come across this before? appreciate your help...

Basing on the stack trace, it seems like a weird file access/
permission problem. BTW, are you correctly prepending the
GWT.getModuleBaseURL() to you rpc's endpoint?

+1 to permission problem. Is this Linux? Did you deploy as root at
some point?

This is Windows XP and no, i did not dploy as root.

[nijoblue]

Yes it is prepended with GWT.getModuleBaseURL();

Anyone know why when generating a client proxy that it needs to write
generated resources to gwt.rpc file???

here is the calling sequence when it failed...

GWT.create(ToppingService.class);
ServiceDefTarget target = (ServiceDefTarget) toppingService;
String relativeUrl = GWT.getModuleBaseURL() + "toppings";
target.setServiceEntryPoint(relativeUrl);
toppingService.getMyObj(new ToppingCallback(label));

the .gwt.rpc files contain list of allowed classes serialization.If
I'm not mistaken, this list is used when the classes involved in RPC
(typically DTOs) do not implement IsSerializable and implement
Serializable instead.

Dear All,

Please Send me server base E.R.P. Software Planning.
In which Database to use.

Secondly pls tell me can I use SQL Server without installing SQL.
Or SQL we can assamble in our setup.

Thanks

Hi nijoblue,

Another possibility (although it maybe a long shot as I would expect
to see it in JBoss console) is you've got this error from Tomcat
somewhere:

java.io.IOException: tmpFile.renameTo(classFile) failed
at org.apache.jasper.compiler.SmapUtil
$SDEInstaller.install(SmapUtil.java:245)

XP is succeptable to this and it's to do with Tomcat reading/writing
JSP/servlet files as it compiles them. If you google "tomcat
tmpFile.renameTo" you'll find it comes up in a lot of different and
obscure contexts. If this is so it would explain why Tomcat can't
write your rpc servlet as per your exception (basically XP is denying
access to the file becasue it thinks some other process is using it).
