Re: [jetty-users] NoClassDefFoundError

Hi

 

You might be on to something  !

The class files resides in a war file under /usr/local/oas/jetty-distribution-8.1.12.v20130726/webapps

and I find that the war file is unzipped to /tmp/jetty-0.0.0.0-8888-Rekvirent.war-_Rekvirent-any-/webapp/WEB-INF/classes

whenever the server starts. I will check with my linux os admin.

But it is perhaps a good idea anyway to let jetty extract the class files to another location. Do you know if it is possible?

 

Per Jørgen.

Could it be that the classes are stored in your tmp folder and occasionally get wiped by your os (or your admin)?

 

Are the actual class files actually found on disk?

You should provide the full stack trace including the cause. NoClassDefFoundError can have several reasons (e.g. serialization issues).

Hi.

 

I am occasionally getting a NoClassDefFoundError on classes defined in my web-service.

I am running a jax-ws 2.2 on jetty-distribution-8.1.12.v20130726 with jdk1.6.0_18.

The NoClassDefFoundError occurs when the class has not been in “use” for some time, typically more than 7 days.

To me it looks like the class “drops” out of the classloader?

To fix this I have to restart the server.   Can someone help ?
