i am not aware indepth but basically we will intergrate through BAPI's to ABAP from JAVA. You can use object and method in java to call bapi.

Hi Rohit,

I think you can go with WebDynpros what is the JAVA based and can be developed in NWDS.

Web Dynpro is used to design user interfaces for Java and ABAP applications.

http://help.sap.com/saphelp_nw70/helpdata/EN/15/0d4f21c17c8044af4868130e9fea07/content.htm

One more way is using JAVA connectors,SAPu2019s new Java middleware, the SAP Java Connector (JCO) allows customers and partners to easily build SAP-enabled components in Java. JCO supports both inbound (Java calls ABAP) and outbound (ABAP calls Java) calls in desktop and server applications.

In this Sample Program we connect to SAP and call two BAPIs.

Import statements: Any program using JCO should contain the following import statement:

import com.sap.mw.jco.*;

Otherwise, you have to fully qualify each class and interface which is very inconvenient.

Connecting to SAP

JCO.Client mConnection;

A connection (or session) with SAP is handled by class JCO.Client

try {

mConnection =

JCO.createClient("400", // SAP client

"c3026902", // userid

"********", // password

"EN", // language

"iwdf5020", // host name

"00"); // system number

mConnection.connect();

}

catch (Exception ex) {

ex.printStackTrace();

System.exit(1);

}

"A Client object is created via a call to createClient(). You can use a specific application server (as in the above code) or a server group (load balancing)." REFER the JCO Javadoc for the overloaded createClient() method for the latter possibility.

"The Client class's connect () method tries to log on to SAP. If that fails for any reason, an exception is thrown. If the call succeeds, we can now stay connected for as long as we like. When we are done, we can call disconnect () to explicitly log off."

for more on JAVA connectors refer the follwing link:
