I want to map a EJB String field as BLOB due to the text is more than 255, I did it like the jbosscmp-jdbc.xml file shows below. Jboss generated error and did not deployed my bean. Inside the jar package,there are other Entity EJBs there. Can everyone help.

In the JBossCMP-Docs, it did not say about which field is compulsory. My TempBean have relationship with other EJB. Do I need to specify the relationship mapping in the jbosscmp-jdbc.xml file?

Without using jbosscmp-jdbc.xml file, my application is running without any problem.

If everyone help, thank U in advanced
