Has anyone been able to compare EJB Adapter and Connector for BEA WLI

Hi everyone,
I have visited the webMethods’s web site, just wonder is there any difference between EJB Adapter for WebLogic and webMethods Connector for BEA WLI 1.0? The webMethods’s document could find nothing about the answer.
Can anyone tell me which’s high-performance?

Any help is appreciated.
