Some bugs inside jboss remote jdbc adapter.

[eblasf]

I use
- jboss-4.0.5
- ojdbc14.zip
- Oracle9i
- WindowsXP

I have found some bugs inside jboss when I access datasource remotly.

1. The code bellow throws NullPointerException when the blob field is empty. failed on org.jboss.resource.adapter.jdbc.remote.WrapperDataSourceService:553

 Blob blob = resultSet.getBlob(column.name());
 bytes = blob.getBytes(1, (int)blob.length());

2. The same code above does not return the contains of the blob when the blob is field.

3. There is a failue on org.jboss.resource.adapter.jdbc.remote.SerializableInputStream:266
Correction should be

 return read(b, 0, b.length);
