Strange NoSuchMethod error

[cyphr]

Hi all,

I've inherited a Spring project from a previous developer and am trying to deploy it for testing. He has it set up in Maven. When I do "mvn jetty:run-exploded", I get this:

INFO: Initializing Spring root WebApplicationContext
ERROR|2008-03-17 11:30:38,813|ContextLoader.initWebApplicationConte xt(203)|Context initialization failed

......several more


I've found exactly one instance of this same error on Google, and there was no fix posted there. Anybody have a clue what could be going wrong?

Different version of Spring in the classpath. Make sure that there is exactly one, not 2. Also if you use the spring.jar make sure there are no spring-*.jar files on your web app.

Also check the classpath/lib directories for another spring version lurking around.

Awesome, thank you so much. Turns out that it was a case of having "spring-2.0.6.jar" instead of "spring.jar".
