Noah,
I'm fairly new to Tomcat.
Can you clarify for me where the
tomcat-startup shell script is located?
Is this the file called:
startup.sh
found in /home/or/bzmclr/tomcat-jwsdp-1.4/bin
where /home/or/bzmclr/tomcat-jwsdp-1.4/
is the home directory for tomcat on my machine.
Also, if I do put a line into this file that points
to the location of the binary (which in my case is equal to:
/export/rainier/cplex90/bin/ultrasparc32_8_6.2
)
will this overwrite some other locations that are part
of SHLIB_PATH by default.
In particular, how do I add /export/rainier/cplex90/bin/ultrasparc32_8_6.2
to
SHLIB_PATH without overwriting what's in
SHLIB_PATH by default?
Thanks for the clarification.
Best regards, Charlie

Hi,
I had a similar issue on an HP-UX server recently. The solution was
to make sure that the SHLIB environment variable is set in the
shell/environment that runs your java process. In my tomcat-startup shell
script, I added the line:
export SHLIB_PATH=$CATALINA_HOME/lib/
In this case, $CATALINA_HOME was my tomcat home directory, and the
library file was in the lib subdirectory.
Hope this helps,
Noah

Re: Having difficulty using native libraries
Please respond to within Web Service running on Axis
axis-user@ws.apac

I am trying to create a web service (that runs on a Sun Unix
workstation) that includes
an optimization library called CPLEX.
I have added the jar file:
cplex.jar
to the directory:
/home/or/bzmclr/tomcat-jwsdp-1.4/webapps/axis/WEB-INF/lib
I found that I had to do this even though I set my
CLASSPATH
to include the location of cplex.jar (which was originally stored somewhere
else).
Now, I'm having trouble because Axis can't seem to find the location
of the CPLEX binaries
This is inspite of the fact that I added the location of the CPLEX Unix
binaries to the path.
In particular,
PATH=/usr/local/bin:/common/site/scripts/midrange:/apps/lsf_appl/bin:/apps/lsf_d
ata:/apps/local/bin:/apps/local/bin/SunOS/5:/usr/openwin/bin:/usr/sbin:/apps/fra
me/bin:/usr/local/bin:/bin:/usr/bin:/usr/dt/bin:/usr/ucb:/usr/bsd:/usr/bin/X11:/
common/ce/scripts:/apps/tex/bin/sparc-sun-solaris2.8:/home/or/bzmclr:/home/or/bz
mclr/bin:.:/usr/openwin/bin:/export/rainier/cplex90/bin/ultrasparc32_8_6.2
and the CPLEX binary is contained in the subdirectory
/export/rainier/cplex90/bin/ultrasparc32_8_6.2
Still, I get the message:
java.lang.UnsatisfiedLinkError: no cplex90 in java.library.path
java.library.path must point to the directory containing the CPLEX shared
librar
y
try invoking java with java -Djava.library.path=...

ava:402)
Also, before the java.lang.UnsatisfiedLinkError is thrown, when I print out
System.err.println(AxisProperties.getProperty("java.library.path"));
I see:
/usr/j2se/jre/lib/sparc/client:/usr/j2se/jre/lib/sparc:/usr/j2se/jre/../lib/spar
c:/usr/lib
which, as you can see, doesn't include:
/export/rainier/cplex90/bin/ultrasparc32_8_6.2
So, even though I have added the directory that contains the necessary
binaries to
the path, once inside the web service, axis seems to overwrite the path to
include
only:
/usr/j2se/jre/lib/sparc/client:/usr/j2se/jre/lib/sparc:/usr/j2se/jre/../lib/spar
c:/usr/lib
If anyone has any thoughs on how to get Axis to correctly read in
the path so that it knows where to search for the binaries, I would
be much obliged.
Thanks, Charlie
