Issue/Introduction

I wanted to implement agent 24.3 in an application on JBOSS 4.3 and the application does not start.

Is it a compatibility problem?

Log error :

Resolution

Using an unsupported JBOSS release. Please review the current SAAS Compatibility Guide. In there, JBOSS EAP 5.2 is the oldest listed version. 4.3 is no longer supported Please upgrade to a supported Agent .
