  • Can you confirm the JDBC version and type of the driver? It seems like you are mixing "type" and "version". DB2 is well tested with JDBC driver Type 4 (100% Java) and JDBC 3.0+. Please, provide the output for the following command: java com.ibm.db2.jcc.DB2Jcc -version

From looking at the code: there is an undocumented hibernate.temp.use_jdbc_metadata_defaults property, setting it to false may help if you can't change JDBC driver:

<property name = "hibernate.temp.use_jdbc_metadata_defaults" value = "false" />

  • Thanx, Found this hibernate experimental code; these experimental code makes open source unworkable without source code.

  • can you let us know what exactly this property does as far as hibernate is concerned?

  • @SibzTer: It disables the call of the offending method. I didn't examined it thoroughly, take a look at the source of SettingsFactory.
