Spring 3 application instantiating a class provided by Tomcat

I have a Spring 3 application that is loading a library. The library consists of JAX-WS generated Java bindings. When the library is included in the WAR file and deployed to Tomcat the application runs great.

However when we moved the library into Tomcat (CATALINA_HOME/lib) Spring is no long able to instantiate classes in the library due to what looks like a classloader issue:

Caused by: java.lang.IllegalArgumentException: interface com.sun.xml.ws.developer.WSBindingProvider is not visible from class loader

Unfortunately we need to keep this library external to the application.

I am stumped on how to correct this issue and would appreciate any suggestions.

-Thanks!

are you sure the directory that you placed the library in, is available in the classpath? we normally place our external libraries in common\lib like this.

%CATALINA_HOME%\common\lib\<yourjar>.jar

And if that didn't work then try explicitly appending the your jar and set in classpath in catalina.bat file.

set CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\common\lib\<yourjar>.jar
