org.springframework.jndi.TypeMismatchNamingException

  Recently, I am going on with a banking program, using Struts + Spring + Hibernate + WebSphere + Maven technology. I often meet with the org.springframework.jndi.TypeMismatchNamingException when I run my problem on the real system. After a long time struggling, I found a approch to this problem.

  Description:
Caused by: org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'java:comp/env/jdbc/DataSourceName'; nested exception is org.springframework.jndi.TypeMismatchNamingException: Object of type [class com.ibm.ws.rsadapter.jdbc.WSJdbcDataSource] available at JNDI location [java:comp/env/jdbc/DataSourceName] is not assignable to [javax.sql.DataSource]

  Approach:

  You should find the lib folder your web project is using, find the calsses12-10.1.0.4.jar, and delete it from your lib folder.
