Hi,
I have a example.csv file (comma separated values) containing millions of records generated from the SAP database.
I want to read this file and insert the same records into Firebird database.
If I use my current jsp based application to read and insert records then after few thousands of records the application terminates with ServletException.
If I use stand alone java program to read and insert the same, it terminates with outofmemory error.
What is the professional and best way to do this? Should I read the file part by part and insert accordinly?
Thanking you in advance

Thanking you in advance.

Hello All,
I am developing a Data Transfer Application using JMS. It involves sending an automatically generated (from database)XML file to a remote server using JMS Queue. I am using Weblogic Server 7.0.
My (simple console) JMS client must have environment (Initial Context) installed on its pc for the messaging to take place.
Is it proper 2 have a fat client(with the environment) in this case?
What is the best way to do this? Is there any other alternative?
Also how does one use a JDBC persistent store in JMS? Any sample code?
Kindly help.
Thanks in advance.

Hello All,
I am developing a Data Transfer Application involving transfer of an xml file to a remotely located computer.
I am planning to use RMI and JMS(Message Driven Bean).
I am using JAXP for generating xml file from local database and then using RMI for transfering it to a remote Weblogic Server which is running a Message Driven Bean.
Can I use rmi protocol(using naming.lookup(rmi://remoteweblogicserver:7001)) in Java RMI client without Initial Context for remote access and t3 protocol at server side for internal transfer of that file to message driven bean?
I am facing difficulties with same. I am unable to use rmi one side and t3 on one side. It gives Connection Refused exception on either side when i test it in my LAN.
According 2 Weblogic documentation,weblogic.rmic is not generating the ImplementationServer_Proxy.class in my case.
Kindly help.
Can t3 be securly used for remote access over internet or intranet?
Thanks in advance.

Hello All,
I have just started using JMS API. I am thru with simple pub/sub example.
But I am unable to store the message( an xml file in my case) using JMS FileStore.
I have created a directory on my local disk and a filestore in the JMS server configuartion.
The .xml file is not saved anywhere.
What extra settings if any are required? Does the sender code automatically saves the file or we need to do some extra coding for this?
Also how is a JDBCStore used?
Can anyone please help me in this regard?
Thanks in advance

Hi there,
Has anyone successfully executed any program involving inserting/retrieving/updating Java Objects in ORACLE thru user defined SQL types?

I think there is some problem with Oracle installation.
Can anyone help? Has anyone worked with SQLJ?
Please reply asap.
