Convert JDBC Connection to EntityManager

[sri ramvaithiyanathan]

Hi,

I am using SAP Server and sap maxdb as database.
While trying to create database connection using entitymanager I am getting following error

 Exception raised from invocation of public java.lang.String com.dbcaller.DBCaller.callDB() method on bean instance 
com.dbcaller.DBCaller@22af96 for bean demo.sap.com/dbear*annotation|demo.sap.com~dbejb.jar*annotation|
DBCaller in application demo.sap.com/dbear.; 
nested exception is: javax.persistence.PersistenceException: 
No Persistence provider for EntityManager named LocalDevelopment~LocalDevelopment~dbejb~demo.sap.com"

I dont know where I am going wrong.

Is there any way to convert jdbc connection to entity manager.

I tried using this way

EntityManager em = (EntityManager)(new InitialContext()).lookup("lookUpName");

but I am getting below error.

class com.sap.engine.services.dbpool.cci.ConnectionFactoryImpl:service:dbpool
@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@891d76@alive 
incompatible with interface javax.persistence.EntityManager:library:
javax~persistence~[e-mail]Loader@af9d74@alive

solved the problem by adding required jar file(eclipselink-2.0.0.jar and eclipselink-javax.persistence-2.0.jar)
