glassfish cannot find sapjcorfc although available

[Former Member]

Hello!

On a 32Bit Linux machine, I installed the sapjco-linuxintel-2.1.8.tgz by

- copying the sapjco.jar into glassfish/domains/domain1/lib directory

- copying included libsapjcorfc.so and librfccm.so into glassfish/lib directory

stefan@server:~$ ls -al /usr/share/glassfish/lib/

insgesamt 61140

drwxr-xr-x 15 root root 4096 2008-02-25 15:30 .

drwxr-xr-x 12 root root 4096 2008-02-13 18:33 ..

... some other files ...

-rwxr-xr-x 1 root root 5046073 2007-01-08 21:40 librfccm.so

-rwxr-xr-x 1 root root 3827533 2007-01-08 21:40 libsapjcorfc.so

... some other files ...

stefan@server:~$

When I now access a Bean that wants to make a call via JCo, my server logs give a lot of Exception, with the following being the main trouble:

at com.sun.enterprise.web.connector.grizzly.ssl.SSLWorkerThread.run(SSLWorkerThread.java:106)

Caused by: java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'

JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc [/usr/share/glassfish/lib/libsapjcorfc.so: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory]. java.library.path [/usr/share/glassfish/lib:/usr/share/glassfish/lib:/usr/share/glassfish/lib]

at com.sap.mw.jco.JCO.<clinit>(JCO.java:776)

In other words, it cannot find the libraries, although they are available.

I tried a number of different things:

- the libsapjcorfc.so in the directory only

- providing a dynamic link called sapjcorfc.so to libsapjcorfc.so

- let sapjcorfc.so be a copy of libsapjcorfc.so

nothing helped.

I'm using the latest Ubuntu version incl. all updates.

Can anybody help me please?

Regards,

Stefan

You should copy sapjco.jar and dll files (sapjcorfc.so) into glassfish bin files.

Hello Eray!

Thanks for your reply.

I tried that, but now I get

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.sap.mw.jco.JCO

Therefore I tried to set the CLASSPATH

- in MANIFEST.MF

- when deploying the Bean in Glassfish (there is an option that allows you to do so)

... both without any success / change (see the Exception above).

it does now look like the following:

glassfish/

bin/sapjco.jar

bin/libsapjcorfc.so

bin/librfccm.so

domains/domain1/lib/sapjco.jar

..but is not working.

I also tried:

glassfish/

bin/sapjco.jar (links to ..domains/domain1/lib/sapjco.jar)

bin/libsapjcorfc.so

bin/librfccm.so

domains/domain1/lib/sapjco.jar

and

glassfish/

bin/libsapjcorfc.so

bin/librfccm.so

domains/domain1/lib/sapjco.jar

... but that didn't work either.

...everytime with the classpath set to /usr/share/glassfish/bin/sapjco.jar or /usr/share/glassfish/domains/domain1/lib/sapjco.jar respectively.

Using Windows, the following setup works:

glassfish\

lib\sapjcorfc.dll

lib\librfc32.dll

domains/domain1/lib/sapjco.jar

Do you have any other idea?

Thank you lots.

Regards,

Stefan
