Hi All Gurus,

Greetings~

We are experiencing the same error. Manickam was your problem resolved, if so how.

Thanks,

From the instruction of the sapjco, here is what I did:

- unzip the two .so file in /usr/lib/SAPJco

- create a system variable to the system startup script (depends on your distro).

LD_LIBRARY_PATH=/usr/lib/SAPJco.

It is avail system-wide then.

(pls award points if it works, it did for me).

> java -jar sapjco.jar

I have ran into this problem on AIX Unix. What I have found is that you need to have the Native Libraries working on the linux box and reachable from the tomcat instance. Meaning, there are two native libraries that need to go into your /usr/lib subdirectory. They should be in the download that you get from SAP. They look like libsapjcorfc.so and librfccm.o.

You can run the sapjco.jar and this will tell you if you have the setup correct.

%JAVA_HOME/bin/java sapjco.jar

You will get a result like below. It will also give you errors if something is not setup correctly.

Hope this helps.

[achim_hauck2]

it seems more a basic tomcat / java problem than a problem inside your servlet. do any other servlets run on your linux-machine?

kr, achim

[Former Member]

Yes. All JSP and Servlet are running. It is only when i make connection to SAP the server goes down.
