问题
I need to connect to SAP Systems via standard BAPI calls. I already installed JCo (sapjco3) and added the .jar to my build path in Eclipse.
But due to the fact that I am rather a beginner regarding network/server programming, I have no idea how to setup a connection between Eclipse and the SAP Systems...can anyone provide a basic solution or some ideas for that?
Thank you and greetings!

I solved the question by myself after having found a good documentation with examples regarding that topic on the SAP homepage. First you need to define a destination, basically setting up your host and all other relevant information for the network connection. You can find it here: http://help.sap.com/saphelp_nwes72/helpdata/de/48/5fb9f9b523501ee10000000a421937/content.htm
Then you can test your connection by creating a method that gets attributes of the server you are connecting with. You can find the code here: http://help.sap.com/saphelp_nwes72/helpdata/de/48/840186ab5a2722e10000000a42189d/content.htm?frameset=/de/48/874bb4fb0e35e1e10000000a42189c/frameset.htm¤t_toc=/de/b4/3f9e64bff38c4f9a19635f57eb4248/plain.htm&node_id=498
The site provides good examples for working with a SAP System in Java.

Setting Up Of SAP Connection using SAP JCO3 in Eclipse IDE One Can Setup SAP Application connection with Java Application using below steps:
Steps to Produce:
- Download SAP Java connectors SAPJCO3 (32bit or 64bit based on your System architecture) from SAP Marketplace.
- Create a separate folder and keep the downloaded sapjco3 zip file and unzip it.
- Copy the location of
sapjco3.jar
file in the newly created folder. - Now go to Environment Variables and create system variables CLASSPATH if not exist and add location of
sapjco3.jar
followed by ;ex: D:\sapjco3-NTAMD64-3.0.16\sapjco3.jar;
- Edit System Variable PATH and add newly created folder location followed by ; ex:
D:\sapjco3-NTAMD64-3.0.16;
- Now Go to Eclipse and Create a new project.
- Create a new Class with any name for connecting to SAP application.
- Right Click on Newly created project and go to build path and click Configure Build Path.
- Click on Libraries and Add External Jars.
- Now select
sapjco3.jar
file just downloaded. - Make your class name as same as you created in step 7.
- Write the Java code

sap2.createDestinationDataFile(DESTINATION_NAME1, connectProperties);
// This will use that destination file to connect to SAP
try {
JCoDestination destination = JCoDestinationManager.getDestination("mySAPSystem");
System.out.println("Attributes:");
System.out.println(destination.getAttributes());
System.out.println();
destination.ping();
} catch (JCoException e) {
e.printStackTrace();
}
}
