Here is the stacktrace when we try to load a Frascati example (helloworld-servlet) in the web explorer : INFO: org.ow2.frascati.examples.helloworld.servlet.HelloWorldHttpServletFCSCAContentControllerImpl INFO: org.ow2.frascati.examples.helloworld.servlet.HelloWorldHttpServletFCscaPrimitiveFC792b8a24 INFO: Compiling... 2011-11-07 10:52:27.458:WARN::/frascati-web-explorer/uploadComposite org.apache.velocity.exception.MethodInvocationException: Invocation of method 'service' in class juliac.generated.javax.servlet.ServletFcSR threw exception org.ow2.frascati.tinfi.TinfiRuntimeException: java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.Compiler.

Eclipse JDT is used by FraSCAti to compile the code FraSCAti generates.
Here you should check that the right Eclipse JDT version is used and present into the classpath. The version should be org.eclipse.jdt:core:jar:3.3.0.771
Perhaps Nuxeo includes another Eclipse JDT version transitively.
There is a problem with the library jsr311-api-1.1.1.jar!/javax/ws/rs/ext/RuntimeDelegate.class =>
Caused by: java.lang.LinkageError: ClassCastException: attempting to castjar:file:/data/home/jguillemotte/EasySOA-Workspace/easysoa/easysoa-distribution/easysoa/serviceRegistry/nxserver/lib/jsr311-api-1.1.1.jar!/javax/ws/rs/ext/RuntimeDelegate.classtojar:file:/data/home/jguillemotte/EasySOA-Workspace/easysoa/easysoa-distribution/easysoa/serviceRegistry/lib/jsr311-api-1.1.1.jar!/javax/ws/rs/ext/RuntimeDelegate.class
Probably because the jaxrs library is already loaded by Nuxeo !? See http://docs.jboss.org/jbossas/guides/j2eeguide/r2/en/html_single/#d0e577
When we try to delete manually the library serviceRegistry/nxserver/lib/jsr311-api-1.1.1.jar : the linkage error disappear > but the loading of web explorer is impossible. A new error is throwed : java.net.BindException: Address already in use. > See how to change the default address used by jetty in web explorer.
Set the Java property 'org.ow2.frascati.binding.uri.base' with a value of form 'http://localhost:PORT' where PORT is the port where the Jetty server will be run. See /trunk/examples/pom.xml

To resume :
The web explorer starts without any problem in test mode but it is not possible to start a composite. There is an error when the generated classes are compiled.
