Implementing createClob() and createBlob() Methods on the Embedded Server
To implement these methods two new constructors have been introduced in
EmbedClob and EmbedBlob having the following signatures
EmbedClob(String clobString,EmbedConnection con)
EmbedBlob(byte  blobBytes,EmbedConnection con)
The set methods in the LOB (JDBC3 methods) are not implemented on the Embedded side.
So the tests basically ensure that the length of the newly created objects in zero
(i.e.) ensure that they are empty initially.
ConnectionTest.java was failing because createQueryObject in
BrokeredConnection40 needed to be forwarded to EmbedConnection40 (i.e.) the
underlying connection that it wraps. I have fixed that up as part of this patch.
