When using Apache JCsIn the process, the following problems occur:

 

Java. Lang. noclassdeffounderror: edu/Oswego/CS/dl/util/concurrent/Channel

At org. Apache. JCs. Engine. Control. compositecachemanager. Configure (compositecachemanager. Java: 203)

At org. Apache. JCs. Engine. Control. compositecachemanager. Configure (compositecachemanager. Java: 192)

At org. Apache. JCs. Engine. Control. compositecachemanager. Configure (compositecachemanager. Java: 149)

At org. Apache. JCs. Engine. Control. compositecachemanager. getinstance (compositecachemanager. Java: 93)

At org. Apache. JCs. JCs. ensurecachemanager (JCs. Java: 99)

At org. Apache. JCs. JCs. getinstance (JCs. Java: 64)

 

Cause:

The concurrent. jar package is missing in the compilation path.

 

Solution:

Obtain the concurrent. jar package and add it to the compiling path (LIB) to re-compile and run it.

 

Concurrent. JarMethods:

 

1Download the source code from the original website and compile it into concurrent. Jar

Download at the Web site http://gee.cs.oswego.edu/dl/classes/EDU/oswego/cs/dl/util/concurrent/intro.html.

 

2In JBoss:

Download the JBoss source code. In the lib directory under the root directory of JBoss, find concurrent. jar and copy it to the compiling path.

 

3, From WebLogic:

Similar to 2, find concurrent. Jar under the installation directory WEB-INF/lib of Weblogic and copy it to the compilation path.
