JNDI lookup works fine using lookUp but not when used in persistence.xml of JPA

Question

I am using tomcat connection pool, jpa, hibernate. The datasource i created in context.xml of tomcat works fine if I try to get it using :

source = (DataSource)          


        

Answer 1

Finally it worked today after i specified the properties below.. because just mentioning the datasource is not enough; we need to specify some properties like which dialect to use. If we specify datasource; we need not specify username , password url of the database ( as all are specified in the datasource configuration itself) .

Most important point is the way you specify the datasource. It should be complete path: java:/comp/env/jdbc/kids . All this while I was missing the slash just before comp.

    java:/comp/env/jdbc/kids
    com.kids.domain.User
