CXF based applet fetching the applet jar several times
Hello
We are developing an applet making web services calls to a server.
We used cxf and from Eclipse, evrything works fine.
Once deployed, the jar is fetched several times from the server to fetch CXF resources, but it seems to me that all the resources are present in the applet jar file.
I remotely debuged the applet and saw calls orignitaed by a getResourceAsStream for resrouces that I can see in the jar.
Here is the Applet pom.xml (we use the shade plugin and cxf 2.6.x)

RE: CXF based applet fetching the applet jar several times
Posted by "Arnoud, Geoffroy" <ge...@capgemini.com>.
Hello
I've tested the hack, it's not better. I've tested with Java 1.6u45 and java 1.7.
As stated before, in 1.7, I don't have class loading slow down - when not doing shading.
Shading is a bit slower.
In 1.6/no shade it's slow (certainly jaxb) and with shade it's worse.
If someone knows how to have the same response time with sading and not shading, it would be nice to tell me.
Best regards
Geoff.

Can you try adding a file to your war/bundle:
/META-INF/cxf/org.apache.cxf.JDKBugHacks.defaultUsesCaches
that just contains a single line:
true
And see if that helps. We have to do a few things to try and prevent the class loader from being locked. JAXB is one of them that does strange things. Adding that file turns off one of the hacks we use that may have an impact on this.

Hi again,
Using java plugin 1.7 doesn't show the strange bejaviour on jaxb-impl.
It remains the issue of shading correctly the jar files.

Hello
I went on investigating.
I stopped shading my applet, and put all explicit deps in archive tag, it's better but not perfect.
Actually I have an issue with jaxb-impl.jar (2.1.13), that is fetched and fecthed again and again. Manually putting it in the lib/ext directory of my java plugin shows good perf, but is not a solution.
Does anyone know why the applet class loader has this behaviour with jaxb-impl?
Regards
Geoff.
