Problem with Axis adapter - handler is not instantiated

[Former Member]

  Hi all,

I did a deployment of an AXIS Adapter on a SAP PI 7.4 SAP PI Installation. When I check the Adapter Message Servlet Status looks fine.

But when I run an interface I get an error from the AXIS communication channel. (Within the channel we use digest authentication)

com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.engine.interfaces.messaging.api.exception.MessagingException: org.apache.axis.ConfigurationException: handler is not instantiated
org.apache.axis.ConfigurationException: handler is not instantiated
at com.sap.aii.adapter.axis.modules.HandlerCore.process(HandlerCore.java:75)

Some hints what going wrong? Or other ideas how digest autehntication can be used.

cheers,

Stefan

Hi Stefan,

Even the Axis Adapter Message Servlet shows not issues with wss4j library, you would need to deploy two more, please check this note  1776179 - Axis Adapter Error: org.apache.axis.ConfigurationException: handler is not instantiated

Thanks for your hint. I was alreday using he correct and needed jar packages.

But I recognized that the system comes in trouble if the the version number is included within the package name.

so wss4j.jar is used but wss4j-1.5.7 can not be used.

What do you think?

Hi Stefan,

I'm not an expert with the Axis adapter libraries installation, but i've just talked with a basis team colleague and our PI has only one wss4j version. If i was you, before to change/delete anything i will try to install the jar pointed in the note, the xmlsec: Maven Repository: org.apache.ws.security » wss4j » 1.5.7

Regards.
