WebServices in EJBs

[Former Member]

Hi,

Is it possible to deploy a standard EJB into the NetWeaver AS and then host a Web Service from this EJB.

After this, Is it possible to call this WebService from outside (EG: A Java APP outside the context of the Server?)

Cheers,

Yes, see [Creating an Inside-Out Web Service from an Enterprise Java Bean|http://help.sap.com/saphelp_nwpi711/helpdata/en/46/78955dcb496ef0e10000000a1553f6/frameset.htm]

After this, Is it possible to call this WebService from outside

Yes, [deploy the Web service|http://help.sap.com/saphelp_nwpi711/helpdata/en/44/f3e0e6e8ce6c30e10000000a114a6b/frameset.htm] and then [create an endpoint|http://help.sap.com/saphelp_nwpi711/helpdata/en/4a/16934f06441b40e10000000a42189c/frameset.htm] for it. Now you will be able to call the Web service.

Hope this helps,

Hi,

That information was very good.

I don't have much experience with EJBs. Can you point me to a step-by-step guide/wiki/blog where the procedure is detailed?

Cheers,

Hi Earlence,

This is a document from the EJB documentation at SAP Help Portal that explains how to expose an EJB as an Web service endpoint:

I hope this helps.
