How to convert a java.sql.CLOB object to String

I have a PL/SQL procedure �reorganize_report� which returns a CLOB object. This proc is being called through a java file named in the following way-

csmt = con.prepareCall("{call report_spk.reorganize_report(?,?,?,?) }");

I am retrieving the Clob�s like this � (the CLOB object is of java.sql.CLOB class)
Clob sourcelocationLst = csmt.getClob(7);
Clob newlocationLst = csmt.getClob(8);
Clob fileNameLst = csmt.getClob(9);

Now I need to convert this CLOB into a String object.
I tried using the toString() function present for CLOB�s but it gives me the following o/p - oracle.sql.CLOB@66c9b250

Can anybody help me out with this?
