Axis2 on Tomcat using Ubuntu: Internal Server Error
Following the tutorials for bottom-up web services for eclipse, I created a dynamic web project and added a few services using Axis2. These web services run without a problem on the local installation of tomcat. However, when I export the web project as war and deploy this war to a tomcat installation on ubuntu, a number of problems occur.
Basically, the war get deployed and started, but after clicking on „Services“ an „Internal Server Error“ occurs. This error depends on a number of exceptions:
„java.lang.NoClassDefFoundError: org/apache/http/HttpResponseFactory “
„load() exception java.lang.ClassNotFoundException: org.apache.axis2.transport.http.AxisAdminServlet“
„org.apache.axis2.AxisFault: The system is attempting to engage a module that is not available: addressing“
The first exception HttpResponseFactory can be resolved by adding httpcore-4.0.1.jar to the folder WEB-INF/lib (just drag and drop in the folder in eclipse).
The other exceptions are a bit tricker. What I found was that the „standard“ installation of tomcat 6 using apt-get does not work correctly.
My problem was resolved after I manually installed Tomcat 6.0.29 loosely following the instructions here.
