java.lang.NoClassDefFoundError: org/springframewor

I have a webapp built using spring framework. I'm trying to deploy this to Tomcat6 using Eclipse. Everytime i make a change to jsp file, I had to clean the build, publish it & then start the server. I believe, we don't have to do all these steps for JSP changes. If i just publish the files, when the server is running, i get the below exceptions

SEVERE: Exception sending context destroyed event to listener instance of class org.springframework.web.context.ContextLoaderListener java.lang.NoClassDefFoundError: org/springframework/web/context/ContextCleanupListener

SEVERE: Exception sending context destroyed event to listener instance of class org.springframework.web.util.Log4jConfigListener java.lang.NoClassDefFoundError: org/springframework/util/Log4jConfigurer

And the war file is not getting deployed in server.

If I make a change to JSP file & then click restart in eclipse, it sometimes publish the files & then start the server. But in some cases, it restarts the server & then publishes the files (in which case i got the above mentioned exceptions & the war file was not getting deployed).

Ideal way that it works is, Stop the server, publish the contents & then start the server. I hate to do this every time i make a simple jsp change. Is there any alternate one click process to do this?

回答1:

There's something wrong with the way you setup your project or server in Eclipse. I'd recommend following the instructions here. Also, you may want to download STS (Eclipse already bundled with Spring support) and use that instead of the vanilla eclipse.

回答2:

Make sure that spring is deployed together with your application. Either set the correct export options in eclipse or copy the spring libraries to /WEB-INF/lib.

MyEclipse works fine here. You could also check JRebel as well. They advertise no redeployments. ;)

you can use exploded war and incremental hot-deploy.

this should work http://www.youtube.com/watch?v=OMtcjgTyP-g
