calling native code
Hi, I am using tomcat 4.1.24 and want to use native c-code with JNI. I have a shared library installed in an oracle subdirectory that is added to the LD_LIBRARY_PATH when Apache is started (apachectl) but when I restart tomcat this directory is no longer in it which leads to a java.lang.UnsatisfiedLinkError: error. Where can I modify the LD_LIBRARY_PATH within tomcat ? When I restart Apache, the LD_LIBRARY_PATH is correct but I get a ClassDefNotFound exeception for the class that calls the c-interface (IprShellInterface.class package com.mot.sps.ipr.common). I have installed that class in CATALINA_HOME/common/classes/com/mot/sps/ipr/common/IprShellInterface.class. I called that class successfully before but now I seemed to have run into a deadlock. Can anyone help? Thanks Astrid
RE: calling native code
Hi there, What OS are you using ? If windows just copy the dll to the windows/system32 directory or solaris to the use/lib directory. That way you dont have to specify the location of the library Thanks Pete -Original Message- From: Astrid Wagner [mailto:[EMAIL PROTECTED] Sent: 05 April 2004 13:13 To: [EMAIL PROTECTED] Subject: calling native code Hi, I am using tomcat 4.1.24 and want to use native c-code with JNI.

I have installed that class in CATALINA_HOME/common/classes/com/mot/sps/ipr/common/IprShellInterface.class. I ran into this problem with linux and tomcat5. I tried every variant of LD_LIRBARY_PATH but no joy. Then I put this line into catalina.sh and everything worked: JAVA_OPTS=-Djava.library.path=/usr/local/jakarta-tomcat/so I put my library.so files into /usr/local/jakarta-tomcat/so take a look at http://www.rgagnon.com/javadetails/java-0348.html HTH Paul - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: calling native code
Hi, I just found out that setting the LD_LIBRARY_PATH var on the shell suffices. When I restart tomcat it takes it from there (working on Solaris 8). Still do not know why I had the ClassDefNotFound exeception after I restarted Apache though. It seems that I always have to go in order 1) Apache and then 2) Tomcat as far as starting is concerned ?!
