Question & Answer
Why would I receive the following message when trying to connect to the IA Collector after upgrading from CICS Interdependcy Analyzer (CICS IA) plugin V5.3.5 to V5.3.7 or V5.3.6 for CICS Explorer:
Couldn't connect. No response from the host received. (200) OK <hostname>:<portnumber>
Here is the Exception Stack Trace:
java.lang.NullPointerException at com.ibm.cics.ia.commands.WebServiceRequest.createGroupElement (WebServiceRequest.java:522) at com.ibm.cics.ia.commands.WebServiceRequest. createAtomContentWithGroupElement(WebServiceRequest.java:438) at com.ibm.cics.ia.commands.WebServiceRequest.run(WebServiceRequest. java:175) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
I have another instance of z/OS Explorer that has V5.3.5 of the CICS IA plugin installed. I can connect successfully to the IA Collector with this version of the software.
I did encounter this problem when I upgraded the CICS IA plugin from V5.3.5 to V5.3.6 in late February.
