I found in [url=https://sourceforge.net/tracker/?func=detail&atid=381174&aid=631825&group_id=22866[/url] the following:
anonymous wrote : | 2. For some reason, previous versions of JBoss mapped java.lang | .Object to a JDBC type of JAVA_OBJECT, and then proceeded to | serialize the object into a binary column. | Some JDBC drivers would accept this behaviour, but many would | not. | JAVA_OBJECT is intended to be mapped to custom types on the | database, and used in conjunction with the java.sql.SQLData/ | SQLInput/SQLOutput interfaces, which are managed by the JDBC | driver. | Therefore JAVA_OBJECT types are now passed straight through | to the JDBC driver via set/getObject. | The standard mappings for java.lang.Object that I was able to test | (as in item 1) have been changed to have a binary JDBC type to | preserve the previous behaviour. | | NOTE: Anyone who has used JAVA_OBJECT in their jbosscmp- | jdbc.xml will need to change it to VARBINARY, | LONGVARBINARY or BLOB to get the previous behaviour. | | IMPORTANT: I have only changed the standard mappings for the | db platforms that I could test. If your database is not mentioned | above I would appreciate feedback on which binary jdbc types are | appropriate. | And the tested/modified databases were: "It has been tested against Oracle 9i, Postgres 7.2 and MySQL 3.23.53, (and hsqldb of course)." Could this have some connection with the problem I'm having?
