Hi,

We always nullify the resultset everytime..but even then error was thrown..

But we got a temporary work around..we altered the table from clob to varchar2(4000) and from then the error is not thrown...

Technically, couldn't explain how it happened...

Thanks and Regards,
Anand

Thanks for your time William

What we do is, when we publish it once it retrives the PageText for selected language(Say English), and when we change the language(to Spanish) it hits the DB and retrives the second set of data and at that time it gives OutOfMemoryError.

Is that related to use of resuleset.getClob method which gives a String[] project in oracle 10G ?

Yes. Tried doing it. But it gives an Exception immediately once its published. Also was wondering anything related to usage of Clob datatype.
While retrieving, am using resultset.getClob method.. Is that anything related to that?
Hi All,

Situation:
--------------
We are loading the page text(Text to be displayed in HTML) from database and the Init Servlet has the code for retrieving the text. Hence while publishing the ear file, the data are prepopulated to the JVM and based on request the page text are displayed.

System Details :
--------------------
Database - Oracle 10G
IDE - RAD 6.0
jdk - 1.4
Ram - 1 GB
OS - Win XP

And the table has 2 varchar2 and 3 Clob datatypes..

Problem:
---------
But when we try to publish it twice or thrice it gives the OutOfMemoryError and gives the below Exception.
