Hi Ganesh,

Use JCO because....

<b>JCO:</b>

Java Connector is a toolkit that allows a Java application to communicate

with any SAP system. The toolkit supports client as well as server functionality.

It combines a flexible API with good performance. The package supports both,

Java to SAP System as well as SAP System to Java calls.

For More reference to this topics.... Please Refer these Links...

Did you also look into JCA way of getting data from SAP R3 using SAP Connectors. You can call BAPI programs from Java using JCA. Take a look at http://help.sap.com/saphelp_nw04/helpdata/en/a9/76bd3b57743b09e10000000a11402f/frameset.htm for Connector Framework.

Hi Ganesh,

<b>For Advantages/Dis-advantages of JCO.</b>

See this pdf. It's very good.

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/ep/_s-u/sap java connector (JCo)%20Presentation.pdf

(Copy & Paste the url).

<b>JCO Cook Book</b>

I assume that web services means that services that are provided by the Web Application Server.

In WAS Server there are 2 stacks. viz., ABAP Stack and JAVA Stack.

The Communication between these two stacks is only using the JCO.

Refer this link from help.sap.com....

http://help.sap.com/saphelp_erp2005/helpdata/en/e1/b5443e02a9ab4186a6e1240a9a2455/frameset.htm

For your information there is something called BSP which is similar to JSP or ASP where

you can have both abap & java scripts in BSP documents.(Business Server Pages).

Refer Conclusion on this page.

So, what i want to say is that you need JCO for integrating j2ee with sap.

Hope it helps.

Thanks & Regards,
