There is really something wrong in custom web services.
We are able to generate the source code even to create .war file and deploy it on Application server.
But when we hit any custom web service we are getting null pointer exception.
This is not just happening with the the custom services that we have developed but same with the standard Helloword Web service provided by OpenText.
Even I tried to deploy the default helloword.war file provided in sdk folder of CS10 instance its also giving us the same issue.
More to that the log4j is not initialised properly in one of the OpenText library file com.opentext.livelink.servic.core.coreservices.CoreServicesFactory. This is the file where the main exception is coming so we are unable to trace that.
log4j:WARN No appenders could be found for logger (com.opentext.livelink.servic
.core.coreservices.CoreServicesFactory).
log4j:WARN Please initialize the log4j system properly.
Below is the stack trace for the same.
