Description tehe 2008-04-04 15:00:59 UTC 
Build: NetBeans IDE 6.0 (Build 200711261600)
VM: Java HotSpot(TM) Client VM, 1.5.0_09-b03
OS: Windows XP, 5.1, x86
User comments: When dropping a database table from the services tab that contains a CLOB column Netbeans cannot work 
with the CLOB and returns an error. Netbeans also does not work when trying to load the clob data using the data 
provider. Is netbeans able at all to use CLOB data?

Comment 1 John Baker 2008-04-04 18:49:31 UTC 
Which version of the Oracle driver are you using?
The supported versions are on this page:

Comment 2 John Baker 2008-04-04 19:27:18 UTC 
I'll need to see your sql script to create your table

As mentioned in 132090 , this article shows CLOBs working with NetBeans:

Comment 3 John Baker 2008-05-13 18:00:31 UTC 
Is this error still occurring?

Any more information you can provide (oracle driver version, schema )

As mentioned read/write of CLOBs do work with Dataproviders
Comment 4 John Baker 2008-05-14 00:53:15 UTC 
User says the same error occurs as 132090 which has a workaround as stated in the comment

"The work around is to add
-Doracledatabasemetadata.get_lob_precision=false

in the JVM options of the application server
