User development, A new message was posted in the thread "howto setup jpa using oracle 10g unicode nvarchar2": http://community.jboss.org/message/530981#530981 Author : jaikiran pai Profile : http://community.jboss.org/people/jaikiran Message: -------------------------------------------------------------- A couple of other options you could try:   1) Try setting this in the -ds.xml:   <connection-property name = "oracle.jdbc.defaultNChar">true</connection-property>   I am not sure whether that will work (I have seen some other users complain that it doesn't work)   2) Pass the oracle.jdbc.defaultNChar as a Java System property through your run.conf (or run.bat for Windows)   -Doracle.jdbc.defaultNChar=true     Add that to the JAVA_OPTS section   P.S: Make sure that you are using the correct Oracle JDBC driver version. From what found in a google search, Oracle 10 driver is required for this property to be recognized. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530981#530981
