The issue is that when I start the server and access the web page, I
get this error:
ERROR [2007-05-23 10:27:34,474] [TP-Processor2]
com.oroad.stxx.plugin.RequestProcessorHelper -
javax.servlet.ServletException: Unable to load xmlform:pipelineForm.xml
cause:java.lang.IllegalArgumentException: InputStream cannot be null
javax.servlet.ServletException : Unable to load xmlform:pipelineForm.xml
cause:java.lang.IllegalArgumentException: InputStream cannot be null

But the application is working fine without any issue.
