Hi i testing the Agent with Liferay 7.1.10/Tomcat. Liferay is starting but without function. I'm not sure what's the right Value for this Parameter is = -Delastic.apm.application\_packages=org.example, i have set it to com.liferay Loglevel for the agent is DEBUG but there is not really interesting to see ``` 2018-09-20 10:16:12.944 WARN [http-nio-8080-exec-31][code_jsp:172] {code="500", msg="", uri=/web/guest/home} javax.servlet.ServletException: Servlet execution threw an exception

Hi and thanks for trying out the Java agent! I'm not familiar with Liferay. The error looks like it could have something to do with OSGi. Does Liferay use an OSGi container, and if yes, which one and which version? Also, which version of Tomcat are you using? Cheers, Felix ---

Hi Felix, sorry for my late answer, unfortunately the Application is shipped as Docker-Images to us. Inside works Apache Tomcat/9.0.6 and if i'm not mistaken OSGi comes in Version 7 [https://community.liferay.com/de/blogs/-/blogs/osgi-version-details](https://community.liferay.com/de/blogs/-/blogs/osgi-version-details) regards Tim ---

Actually we set the [`org.osgi.framework.bootdelegation`](https://osgi.org/specification/osgi.core/7.0.0/framework.module.html#framework.module.parentdelegation) property to `co.elastic.apm.*` exactly for that reason - so that the agent classes can be found in OSGi containers. I'm not sure why it does not work with liferay 🤔 ---

Hi Felix, after RTFM , this is for Liferay not enough :-D. per default in Liferay the Agent-Classes not visible for OSGi(a "feature" from Liferay 😉 ) it is necessary to add the following to the portal-exe-properties file ``` module.framework.properties.org.osgi.framework.bootdelegation=\ __redirected,\ com.liferay.aspectj,\ com.liferay.aspectj.*,\ com.liferay.portal.servlet.delegate,\ com.liferay.portal.servlet.delegate*,\ com.sun.ccpp,\ com.sun.ccpp.*,\ com.sun.crypto.*,\ com.sun.image.*,\ com.sun.jmx.*,\ com.sun.jna,\ com.sun.jndi.*,\ com.sun.mail.*,\ com.sun.management.*,\ com.sun.media.*,\ com.sun.msv.*,\ com.sun.org.*,\ com.sun.syndication,\ com.sun.tools.*,\ com.sun.xml.*,\ com.yourkit.*,\ sun.*,\ co.elastic.apm.* ``` i hope that's all, the Application is starting without Exception ... i'm still testing ... ---
