Hello NetDyners,
I am trying to use the java.lang.reflection to dynamically instance
a class object based on a variable, contains the name of the class.
as shown. The strClassName can be anything, spider.session.CSpString,
spider.session.CSpInteger, etc.
cspSltTest -is a dataObject.
strClassName - "spider.session.CSpString"
Class cls = Class.forName(strClassType);
Object o1 = cls.newInstance();
o1 = cspSltTest.getValue(iRowIndex, COLUMN_NAME);
& try using it like say,
cspH1.put(strKey, (CSpValue) o1)
where cspH1 is a CSpHashTable.
This throws the following error.( shown at the end)
The error message says: Local class not compatible
Any help or suggestions will be greatly appreciated.
Thanks,
Raj
