RE: JNI with AXIS - InvocationTargetException

[Martin, Richard]

Title: Message

Hi Sai,   I'm not sure what container you are running Axis in. However there is an entry in the Tomcat 5.0 release notes relating to JNI with tomcat: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/RELEASE-NOTES.txt   The following is copied verbatim:   ------------------------------------- Tomcat 5.0 and JNI Based Applications: ------------------------------------- Applications that require native libraries must ensure that the libraries have been loaded prior to use.  Typically, this is done with a call like:   static {     System.loadLibrary("path-to-library-file");   } in some class.  However, the application must also ensure that the library is not loaded more than once.  If the above code were placed in a class inside the web application (i.e. under /WEB-INF/classes or /WEB-INF/lib), and the application were reloaded, the loadLibrary() call would be attempted a second time. To avoid this problem, place classes that load native libraries outside of the web application, and ensure that the loadLibrary() call is executed only once during the lifetime of a particular JVM.   -------------------------------------     I'm not sure whether this has any relevance to your container but I remember reading that there was a similar problem with Tomcat 4.x series of applications, and it looks like the steps listed above might be true of other servlet containers as well.   Hope this helps,   Richard -----Original Message----- From: Sai Pradeep - Hotmail [mailto:[EMAIL PROTECTED] Sent: 13 January 2004 00:42 To: [EMAIL PROTECTED] Subject: JNI with AXIS - InvocationTargetException Hi All!   I came to know from the mailing list that many people used Jni with Axis. My task was to develop a web service which can invoke a JNI. Whenever I try to invoke jni from my service I get an Exception "InvocationTargetException". When i try to run this jni application without deploying it on the Axis, everything seems to work fine. I would be grateful to you, if anyone of you could be able to get me out of this Exception.   Cheers Sai.
