HI,

Since webdynpros follows Model View Controller Architecture You can access EJBs in webdynpro(views/frontend) infact to connec to database uding JDBC you have to utilise EJB ( opening connection to database closing, and other Business functionality).See this link

Hi,

Its pretty simple to access the EJB hrough web dynpro. You can create the EJB in the J2EE perspective and access them in the webdynpro code as you do in the case of simple Java Program.

HElp can be found in the nds help.

Please direct question related to webdynpro in the webdynpro forum

Hi,

wit addition to Noufal's suggestion, you have to add the ejb.jar file of your EJB project to the classpath of your WD project and in the WebDynpro sharing reference property you have to add the reference to the EJB application project. After this you can successfully access EJBs from your WD code. You can also expose your EJB business methods as local web services and access them via Web Service model in Web Dynpro.

Hope it helps!!!
