Unable to use EJB adapter in EI error Not available

I configured an EJB adapter on websphere 4.0.1 and enabled it in Configurator. Its running and can see the green light. But when I try to create a new configured operation using EI, I get this error. Any ideas gentleman…

Not Available (516-5160): This operation cannot be completed because the adapter process TestHomeEJBAdapter is not running or has not been contacted yet.

I have similar experience of the EJB adapter. I also tried to setup communication with an EJB on WebSphere. I made serios efforts but my adapter never became stable. Sometimes I could get it up and running with the tutorial examples, but I never managed to communicate with my own EJB. I got similar errors as you.

Therefore I decided to not use the EJB adapter. Instead I implemented a custom adapter which communicates with an EJB on WebSphere. This works fine. The only complication is that it is necessary for the custom adapter to use a WebSphere JRE (or IBM JRE). Several WebSphere jar-files must also be present in the classpath.

Thanks Martin for the feedback, got EJBSP2 from webMethods support and it solved the issue, if I find the adapter to be clumsy, I’ll go with custom but it seems to be ok right now.

Hi, Adnan,

I tried last night and seems EJB adaper has some bugs when a EJB methodvparameter has type of ‘Date’. I’ve change the parameter type from Date to long, and it works fine.
