Getting java.lang.ClassNotFoundException: com.wily.introscope.agent.probe.io.ManagedFileInputStream on Wildfly 8.2.0

[Itamar Budin]

Hi

 

We are trying to configure an APM 10.5.2.15 agent on our Wildfly 8.2.0 running on CentOS 6.4 with JDK 1.8_71 and we are getting the following error:

We tried to use the following JVM argument:

 

-javaagent:/opt/CA/VirtualAppliance/custom/wilyagent/wily/Agent.jar -DagentProfile=/opt/CA/VirtualAppliance/custom/wilyagent/wily/core/config/IntroscopeAgent.profile -Djboss.modules.system.pkgs=org.jboss.byteman,org.jboss.logmanager,com.wily,com.wily.* 

 

but it doesn't work

 

please help

 

thanks in advance

Which JBoss version are you using?

 

According to the link below, the options are switched with -Djboss coming before the -javaagent.

Your profile property is incorrect:

 

-Dcom.wily.introscope.agentProfile=<path-to-agent>/wily/core/config/IntroscopeAgent.profile

[Matthew Muskaloon]

Good catch Hiko, I blew right past that.

[David Lewis]

That's the new simplified form, it does work in general, this seems like a sort of OSGi issue that would normally be resolved with putting com.wily, com.wily.* in the list of packages..

Certainly would help to see the other startup parameters.
