JAX-WS classes not generating in Eclipse

I have a project that uses annotation processing + jaxws to generate WS interfaces,

but Eclipse (Flexbuilder) will forget about them.

I have to go in, toggle the 'use annotation processing' flag,

restart IDE,

toggle and hopefully it builds them this time so I can export a war file.

Server-side symptom:

Jul 22, 2009 3:45:24 PM org.apache.catalina.core.StandardContext listenerStart

SEVERE: Exception sending context initialized event to listener instance of class com.sun.xml.ws.transport.http.servlet.WSServletContextListener

com.sun.xml.ws.transport.http.servlet.WSServletException: WSSERVLET11: failed to parse runtime descriptor: runtime modeler error: Wrapper class com.blah.blah.jaxws.MyClass is not found. Have you run APT to generate them?

at com.sun.xml.ws.transport.http.servlet.WSServletContextListener.contextInitialized(WSServletContextListener.java:118)

at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3764)

...

It seemed like I tried both combinations...

I check in windows explorer just to make sure the .apt_generated isn't there and not showing up.

I check the properties -- the folder is read-only (probably due to the VSS checkout); I turn this off.

Excellent... I don't see the .apt_generated folder there; perhaps its existence is fleeting.

But I do see generated classes in the build directory.

Oh, now I see .apt_generated at the project toplevel (not in src)...

so, it works.. probably was the folder permissions, there's definitely some bugginess here.
