Re: JNI error under tomcat: java.lang.UnsatisfiedLinkError

Had You tried to made c header by javah -jni ./your_packages/your_class.class ? It gives header for You with properly named method to be written in c.. On Mon, Jul 5, 2010 at 4:11 PM, Konstantin Kolinko wrote: > 2010/7/2 dennis ch : > > Do I miss anything here? Any input is appreciated! > > > >

Re: JNI error under tomcat: java.lang.UnsatisfiedLinkError

Hi Shay, Thanks for your input. And yes, I did see the "Load library successful" message. I've also fixed the code with static { } block. However, I still received the same error message. Any other thoughts? Thanks, Dennis 2010/7/2 Shay Rojansky > Hi Dennis. > > So do you see the "Load lib

Re: JNI error under tomcat: java.lang.UnsatisfiedLinkError

Hi Chris, Thanks for your reply. I recompiled everything and checked method signature, but still got the same error. I felt it's weird why it worked for standalone app but not deployed web service... Thanks. model.java public static void initModel() { modelJNI.initModel(); }

Re: JNI error under tomcat: java.lang.UnsatisfiedLinkError

Hi Dennis. So do you see the "Load library successful" message? Also, if I remember correctly, the code in eval.java is not a safe way to load a native library. It's a very good idea to place the System.loadLibrary in a static { } block, instead of in a method. The way your class is written, it's

JNI error under tomcat: java.lang.UnsatisfiedLinkError

Hi, I have a java class (eval.java) that invokes a native method in an so file (libmodel.so, using SWIG 1.3.29 to generate JNI code/wrapper and compiled the library). I can use System.loadLibrary() to load the libmodel.so without any error (-Djava.library.path=/usr/lib), and the native method init
