Space in JDBJ.ini

Make sure space is not embedded between '=' and the value for a property in JDBj.ini

example:

tns= C:\oracle\product\10.2.0\client_1\network\admin\tnsnames.ora

might complain unalbe resolve a tns string.

Make sure it is "tns=C:\oracle\product\10.2.0\client_1\network\admin\tnsnames.ora"
