Hi , I am trying to install app agent on an application hosted on IBM Portal server. On adding the JVM arguments , application is starting successfully . However after main login page , application is not working. It is throwing
exception. Application is not writing logs as well. Has anyone experienced such issue ? Can someone suggest how to proceed troubleshooting this? There is no error in the agent logs and application logs.
There are other application hosted on the same server , they are working fine with appagent,.
We have ever had this behaviour, caused by an incompatibility of Dynatrace with some class of framework used (an OSGI Application whose the contract has been modified by Dynatrace Instrumentation).
But, it generated errors in logs so we could have found the class occured this errors.
Do you find some "java.lang.IllegalAccessError" error in your logs ?
To correct this error, we have exluded guilty class in Dynatrace Configuration on JVM parameters of your application
Example on IBM Portal Framework :
For this class : com.bowstreet.webapp.util.WebAppSchema
you add this configuration
It just an example, WebAppSchema Class don't throw your error or maybe, so i'm lucky 😉
