Using JNI (to get C++ routines) with Java : NetBeans IDE 7.1.2
I want to call a series of C++ routines from java using the Java Native Interface. 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 second part is the wrong part. The second part is my feeble attempt at changing my code so that it invokes a routine in the C/C++ library.
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.
Start NetBeans, highlight the name of the current project, right click on it, 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 were given to me.
The 2 jar files now appear on the left side of the IDE under MY_TEST.
0) FYI: There is only one class in this simple dot java program.
1) I put a call to a method (my_test) listed in one of the jar files (my_test does not exist anywhere else),
2) in the same dot java file, I created the following routine prototype formy_test:
"private native void my_test()", and
3) at the start of the class (in the dot java program) add the lines:
System.load ("C:\\User_name_0\\dist\\name_of_jar_file1.jar" );
System.load ("C:\\User_name_0\\dist\\name_of_jar_file2.jar" );
This compiles, but I get the following runtime error:
java.lang.UnsatisfiedLinkError: C:...\dist\lib\JavaGxpApiClient.jar: Can't load this .dll (machine code=0x23) on a IA 32-bit platform
What do I do. Would creating a dot h file help.
