The error came from this line in the code : final ActiveXComponent excel = new ActiveXComponent("Excel.Application");

Answer 1

When you load libraries that have a native component (like the jacob library), you should make sure to load them once only. The agent runtime however loads every run using a separate class loader instance. You probably can have success with an XAgent and a application scope managed bean.

Running client type apps (like Excel) is never a good idea on a server
