Unfortunately, I had the person roll back the STAF install to our compiled 
3.1.3, but what was installed was 3.2.0. I wonder if our issue is due to a 
requirement that we use a 1.4.2 JRE since the applications we are using 
use that JRE and do not support anything newer.

Re: [staf-users] Problems on Linux with Java Service





We run STAF on many different version of Linux, as do many other STAF 
users, and use Java services on Linux with no issues.

What version of Linux are you using?    uname -a
What version of Java are you using (please provide the complete output 
from the following)?    java -version
What version of STAF are you using?    STAF local MISC VERSION

[staf-users] Problems on Linux with Java Service








About a year ago when we moved to STAF v3, the person doing the work 
determined there was a problem with Java Services for STAF on Linux. To 
resolve the problem, he re-compiled STAF for Linux and we have been using 
our own copy of STAF 3.1.3 since.  This recently came up again as someone 
here set up a new machine & went out to the STAF site for the latest 
download...  Unfortunately the person who did this work is no longer here, 
so I can't get any more details! 

I thought a defect was filed on this issue, but can't find one on the STAF 
site. Also searching the forums, I don't see that anyone else has this 
problem. So,  I'm starting to suspect it might be something 'special' 
about us. Thought I'd check in with folks to see if anyone else gets a 
Java Core dump immediately on requesting a STAF handle on Linux. The 
interesting part of the core dump file is: 

-------------------- 
  "main" (TID:1006B9B8, sys_thread_t:80773D0, state:R, native I 
5 
      at java.lang.ClassLoader$NativeLibrary.load(Native Method 

      at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:21 

      at java.lang.ClassLoader.loadLibrary(ClassLoader.java:202 

      at java.lang.Runtime.loadLibrary0(Runtime.java:824) 
      at java.lang.System.loadLibrary(System.java:910) 
      at com.ibm.staf.STAFHandle.<clinit>(STAFHandle.java:100) 

I'd be interested to know if anyone else is using STAF with Java Services 
on Linux and does not see this problem? In that case, I'd be interested to 
figure out what's different in our code or environments.  We'd like to get 
out of the business of keeping our own copy of STAF for Linux. 

Thanks for any help.
