Hello,

Hello Sarika,

sapjco.jar is the JAR of JCo 2.1. It is supported only for JVMs up to Java 1.4. Hence, you should not use it with Java 1.7. Furthermore, JCo 2.1 is out of support for more than 2 1/2 years now. Therefore, you should use JCo 3.0 for your projects.

Best regards,

Markus

Hi Sarika,

as you did not mark Markus reply as the correct answer but only as a helpful one, you seem to expect to get another reply.

So hopefully making this complete:

Markus is absolutely right. But you CAN use the old sapjco.jar in Java 1.7, but to stress it once again: you SHOULD NOT!

SAP does not support this and also never provided support for such a scenario in the past.

Some functionality of JCo 2.1 will not work with Java 7. Known issues are wrong field values and exceptions if working with java.math.BigDecimal instances and potential crashes if working with JCO.Throughput instances. JCo 2.1 was never tested in Java 1.7. Its usage within this environment is completely at your own risk.

Please see note 549268 for the official JCo 2.1 release and support strategy.

Best regards,

Stefan

Now after I have written a more detailed answer you changed Markus' reply from being helpful to be the correct one?

Thank you very much for not rewarding any points to mine!

I will know it better the next time...

JCo is only available to SAP customers and partners. So indeed, you need an appropriate S-User ID with SWDOWNLOAD authorization object to be able to download this software.

Please ask your local SAP Super-Administrator for getting such an ID and permission.
