Hi All,
We have a requirement where an application will monitor the JBOSS server to check Appian's interaction with the database. We have placed the JAR file in the lib folder of the JBOSS home and have also added JAVA_TOOL_OPTIONS in the standalone.bat file . But after restarting the Appian engines/ search-server/JBOSS when we try to open Appian Tempo we are seeing nothing inside the page (not even the tabs), just the sky blue color background. Also if we try to open any interface/process models we get to see the "Error-404 page not found" error(attached screenshot). Any help is much appreciated.

What did you add in JAVA_TOOL_OPTIONS ? You might be introducing a class loader error.

Check the server.log during the start-up, if you see a NoClassDefFoundError or similar then it means Appian is not compatible with this tool.

Hi Eduardo,
We added the path of the jar file in JAVA_TOOL_OPTIONS.
Yes, that is the error which we are getting in the server log. Thanks a ton Eduardo!

Here is an extract from the server log pointing out the errors.

Ok my first answer was correct then. I can clearly see the agent is causing a class loader issue that impacts the OSGI framework needed for plug-in deployment and some modern UI components of Appian.
