Unsatified link error with Java 1.6 on IA64/11.31 -

Christian H. — Tue, 24 Feb 2009 10:04:09 GMT

Hello,
we are trying to run an SAP JCO Java client to connect to a SAP Application server. For this a JCO native library is needed. The JCO connect application is running on an HPUX IA64 - 11.31 IA64.
I'm using Java1.6.0.01-jinteg.

I have tried to set the LD_LIBRARY_PATH and SHLIB_PATH to the sap jco native libraries but nothing helps. I always get the exception:

java.lang.UnsatisfiedLinkError: no sapjco3 in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682) at java.lang.Runtime.loadLibrary0(Runtime.java:823) at java.lang.System.loadLibrary(System.java:1030)
...

The enviroment is set in this way:
=========================
LD_LIBRARY_PATH=/opt/java6/bin:/opt/java6/lib:/sapmnt/PT1/knapp/bin/../lib/sap_jco/hpuxIA64:/usr/lib:/usr/lib/hpux64:/opt/langtools/lib/hpux64:/opt/java6/jre/lib/IA64N/hotspot:/usr/lib/hpux64
=========================
SHLIB_PATH=/opt/java6/bin:/opt/java6/lib:/sapmnt/PT1/knapp/bin/../lib/sap_jco/hpuxIA64:/usr/lib:/usr/lib/hpux64:/opt/langtools/lib/hpux64:/opt/java6/jre/lib/IA64N/hotspot:/usr/lib/hpux64

I have tried 'chatr +s enable /sapmnt/PT1/knapp/lib/sap_jco/hpuxIA64/libsapjco3.so' with this result:
//sapmnt/PT1/knapp/lib/sap_jco/hpuxIA64/libsapjco3.so:

But this didn't solved the problem.
Some ideas what to setup?

Are you invoking java with -d64?

Yes!

Christian,

I know almost zip about java, but given that it seems to be failing in the class loader, doesn't that imply that it will be looking for sapjco3 in the CLASSPATH, not the library path?

I have checked this.
The sapjco3.jar is in classpath.

By the way.
Sorry for the duplicate thread. But on the "languages and scripting" forum i got only one reply.

Thanks
Christian

>The sapjco3.jar is in CLASSPATH.

What about libsapjco3.so?
If you have a java question it seems you'll need to talk to the Response Center.

You may want to use "tusc -fp java ..." to see what files get opened and paths used.

Ok, i have added the libsapjco3.so to the classpath, too.
But still the same error "java.lang.UnsatisfiedLinkError: no sapjco3 in java.library.path"

I will talk the responsible sys admin to install "tusc".

Hello,

after studying a lot of documentation it works fine.
The first error was invoking the jvm with -D64, but it must in lower case -d64.
The second error are, the position of the argument of java must be this switch. If it is not the first argument it will not work in 64 Bit mode.

Thanks
Christian

Yes, I asked that first. :-)
