The IDE that I'm using is NetBeans 7.1.2. Below is a two part description. The first part is background. It explains = how I was told to setup two jar files that refer to my C++ routines. The se= cond part is the wrong part. The second part is my feeble attempt at changi= ng my code so that it invokes a routine in the C/C++ library. (Part 1) I setup NetBeans to use 2 dot jar files to refer to my C++ routines. I was = told to follow these steps. The steps that I followed to do this are.=20 Start NetBeans, highlight the name of the current project, right click on i= t, select Add Library, select Create..., name the library MY_TEST, click ok= , press the "Add JAR/Folder..." button, and select the two jar files that w= ere given to me. The 2 jar files now appear on the left side of the IDE under MY_TEST. (Part 2) 0) FYI: There is only one class in this simple dot java program.=20 1) I put a call to a method (my_test) listed in one of the jar files (my_te= st does not exist anywhere else), 2) in the same dot java file, I created the following routine prototype for= my_test: "private native void my_test()", and=20 3) at the start of the class (in the dot java program) add the lines: static { System.load ("C:\\User_name_0\\dist\\name_of_jar_file1.jar"); System.load ("C:\\User_name_0\\dist\\name_of_jar_file2.jar"); }=20 This compiles, but I get the following runtime error: java.lang.UnsatisfiedLinkError: C:...\dist\lib\JavaGxpApiClient.jar: Can't = load this .dll (machine code=3D0x23) on a IA 32-bit platform What do I do. Would creating a dot h file help. Thanks, First Time JNI user
