Hi Sabine

See this link to the SAP Help docs for an explanation: [http://help.sap.com/saphelp_nw04s/helpdata/en/f2/db49421c0b3c54e10000000a1550b0/frameset.htm]

Here's a brief quote from the link:

The connector framework has connection management. This overcomes a common problem that occurs when using the JCo client service, where the developer hat to take care about connection management himself. Therefore it is strongly recommended not to use JCo client service any more and migrate existing EP 5.0 applications that use the JCo client service to Connector Framework.

You'll definitely be able to find more detailed explanations if you search SDN, but this is just a quick explanation if that's all you needed to convince yourself.

Hello,

thanks for the site.

Can I use a different connector or alternativ to connect from J2ee to sap R/3? I don´t want to use BAPI because I dont know how I write an ABAP programm .

Hi Sabine

I don't understand what you're trying to do. Please could you explain the scenario, and I'll try help you.

If you don't call a BAPI / Function Module, then what are you calling in SAP? What are you trying to do by connecting to "R/3"? Also, "R/3" is an old name that is often incorrectly used to refer to many different components of SAP. Please let me know exactly what functionality you're trying to use within SAP?

Hello Stuart,

i would like read from the table "PROJ". I know, there are BAPIs which i could take. I have to use the JCO to call the BAPI from an external system. I am interested in alternatives. There is the SAP Business Connector. I was happy as I read about xml, but i have to use although BAPIs. Sorry my english is bad. Is there more alternatives which i can take to connect and read data from Sap?

I dont use SAP Web application server.

thanks

regards

Hi Sabine

Please don't worry about your English - it's good enough for me to understand what you're saying.

One option you could consider is exposing the relevant BAPI's as web services. You can find instructions on this [here|http://help.sap.com/saphelp_nw04/Helpdata/EN/76/249f02f5235b44b4dc6abbce35f44a/frameset.htm].

This obviously depends on the volume of data you want to transfer, as web services have lower performance than binary data transfer (e.g. RFC, etc.)

This option will probably be the easiest, especially since your application is not running on NetWeaver (if I understood you correctly).

You also don't need any ABAP programming knowledge to expose an existing BAPI as a web service, so this should make things a little easier for you.

Good luck!

Cheers

Stuart
