Java Agent fails to start

When starting the java agent under tomcat 9 using version 4.4.0.4 I get the following exception. The agent is configured in setenv as set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:"C:\appdynam\Agents\ver4.4.0.4\javaagent.jar".

 

Any ideas how to fix this?

Re: Java Agent fails to start

What JDK version are you using to run tomcat?

Can you provide your agent logs (they will be in C:\appdynam\Agents\ver4.4.0.4\logs\XYZ)

 

Warm regards,
Peter

The logs directory is empty. I am using jdk1.8.0_144

Re: Java Agent fails to start

That is very odd.  I think this is best investigated interactively via a support ticket; could you open one?

Re: Java Agent fails to start

Hi Alan,

 

that happened to me before (with previous agent versions) and my problem was this (referring to the doc):

 

The user under which the JVM runs must have write privileges to the conf and logs directories in the Java Agent home. To achieve this, you can install the agent as the same user that owns the JVM or as an administrator on the host machine. You can restrict the remaining contents of the agent directory to read only access.

 

Did you check if the user has permission to the conf and logs directories? (that could be the reason the log directory is empty)

 

Best!

Re: Java Agent fails to start

Thanks Julia. I checked the permissions and everything looks good.

 

Did you get this exception is the past? java.lang.ArrayIndexOutOfBoundsException: 25

 

I have a ffeling that the error occurs before it writes to any logs.
