Well, I'm not sure, but maybe a classloader related problem i.e. the classloader used to load sqlClob class is not the same used to load the class you listed here.I am refitting existing production code to use dbcp BasicDataSource for connection pooling instead of a home grown connection pooler.
A big problem has arisen in that running against Oracle the dbcp.DelegatingResultSet is returning a clob which getClass().getName() says is an oracle.sql.CLOB but instanceof does not recognize as such.
java.sql.Clob sqlClob = rs.getClob( i + 1 );
String temp = sqlClob.getClass().getName(); // is 'oracle.sql.CLOB'
if(sqlClob instanceof java.sql.Clob) // is TRUE
if(sqlClob instanceof oracle.sql.CLOB) // is FALSE when running with dbcp
This code works without using dbcp.
Any ideas?
If it is so, the two classes are not the same class. the test against java.sql.Clob gets true because java.* classes are loaded by a classloader who is parent of all the other classloader (well, beside the bootstrap one).
Hope that helps, Federico
thx
