hi everybody, i am chaitanya, i have a serious problem with tomcat6.0 server. i am struggling since 2 days.
Previously i developed a web application using websphere application server. now i migrated my server from websphere application server to tomcat6.0 server.
previously i developed the application with websphere and java1.4 and ibm db2.
i am using ibm db2 database. i used user dsn to connect to database through my application. it was successful. recently i came to know that we have to use system dsn to connect to database. i modified the connection. again it was a success.
now i migrated to tomcat6.0 and java1.5 and ibmdb2.
i just deployed my application on tomcat6.0. the deployment was successful. when i am trying to execute the project an error is coming. the application is unable to connect to database.
this is the error message when i am trying to connect with system dsn.
----------------java.sql.SQLException: [IBM][CLI Driver][DB2/NT] SQL0204N "SYSTEM.EMP_DETAILS" is an undefined name. SQLSTATE=4270
this is the error message when i am trying to connect with user dsn.
----------------java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
i thought that the problem is with java1.5. so i reconfigured the server with java1.4. the installation of tomcat6.0 was sucess. but the server is not starting. so i once again reconfigured the server with java1.5. then the server started. why is this happening?
i thought that the problem lies with the database so i shifted the database to oracle. then also the same problem is arising.
Hi Anusha. DON'T use the JDBC/ODBC bridge driver. It's water buffalo dung, except that if you spread it on plant's they'll die. It's only intended as a last-resort facility when no better driver is available. In the case of DB2, IBM provides several native DB2 UDB JDBC drivers and you should be using one of those.
