Engine environment problem with axis and embedded tomcat.

[Hitesh Patel]

Hi,

Recently I have been trying to deploy Axis 1.2.1 with embedded tomcat 5.0.28, and facing some weird problems. When I deployed the same release of axis with standalone tomcat (same version), it just worked fine. Also, the embedded tomcat works fine with all the other web applications except axis.

 

The configuration test page ("happyaxis.jsp") seems to be happy, it found all the needed core libraries.

 

When I try to list the deployed web-applications from the index page (http://localhost:8080/axis/) it throws  following exception.

java.lang.NullPointerException at org.apache.axis.transport.http.AxisServletBase.getEngineEnvironment(AxisServletBase.java:273)
Any help would be appreciated.
Thanks,
