starting clipsjni

[Arpit]

hello,
I am on linux platform(ubuntu) and was getting some problem with
starting clipsjni.
I have executed the make command(as given in the document) 'make -f
makefile.linux'. It worked fine but then when i try to run clipsjni as
follows:

java -cp CLIPSJNI.jar CLIPSJNI.Environment

it says an error: Could not find the main class: CLIPSJNI.Environment.
Program will exit.
Any help in this regard??
P.S: I am a beginner so plz explain in a basic manner ;)
Thanks

Hi Arpit,

1) Modify the makefile with your java-jdk path
(-I/usr/lib/jvm/java-6-sun-1.6.0.26/include/
-I/usr/lib/jvm/java-6-sun-1.6.0.26/include/linux/ for ubuntu) // I
assume you managed to do this
2) cp library-src/libCLIPSJNI.so .
3) java -cp CLIPSJNI.jar CLIPSJNI.Environment

Hi Lode,

I have set the path for java-openjdk in the makefile but I don't know where to set cp library-src/libCLIPSJNI.so. I mean, do I have to set it in the makefile itself and how exactly(like after which line and between which delimiters).

If I am correct the cp here stands for classpath ....right?

Thanks.

No, you should copy the .so file to the folder where your .jar is located. They belong together. Sorry for the confusion.
(cp = copy)

[Arpit]

Yes precisely....that I did already.

But it said "Could not find the main class: CLIPSJNI.Environment. 

[Lode Hoste]

ok I don't know what could be wrong but to help you further, please
report the output of the following linux commands:

0) go to the folder where your jar and .so file is located
1) "uname –a"
(checking 32 vs 64bit)
2) "du -h *"
(to see whether the .so was compiled successfully)
3) "java -version"
(if you are using openJDK, you could try to install the Java from
Oracle: http://www.ubuntugeek.com/how-to-install-oracle-java-7-in-ubuntu-12-04.html)

that's not the folder where the jar is located

try to change to the oracle java vm using this guide:
http://www.ubuntugeek.com/how-to-install-oracle-java-7-in-ubuntu-12-04.html

I tried following the steps given on ubuntugeek.com but it gave an error. So I am continuing with openjdk.

And, by the .jar file which file do you mean? Is it the CLIPSJNI.jar located in the main directory or some other directory. 

When I run 'du -h' in the main directory ('CLIPSJNI v0.3') it gave the output as specified in the previous mail. When I run it in library-src, it  gave '9.9 M'.

And also, I have copied the .so file to the main directory 'CLIPSJNI v0.3', and it still gives the same error.

Any help?

ok, let's retry this step by step:

1) unzip CLIPSJNI.zip
2) cd CLIPSJNI/library-src
3) edit makefile.linux
- gcc -o libCLIPSJNI.so -shared -Wall
-I/opt/sun-j2sdk-1.4.2/include -I/opt/sun-j2sdk-1.4.2/include/linux
-lm $(OBJS) CLIPSJNI_Environment.c
-> gcc -o libCLIPSJNI.so -shared -Wall
-I/usr/lib/jvm/java-6-openjdk/include
-I/usr/lib/jvm/java-6-openjdk/include/linux -lm $(OBJS)
CLIPSJNI_Environment.c
4) make -f makefile.linux
5) copy libCLIPSJNI.so to your CLIPSJNI main folder, where the .jar is
also located
6) In your 'main' folder you now have:
libCLIPSJNI.so
CLIPSJNI.jar
7) execute the sample "java -Djava.library.path=. -cp CLIPSJNI.jar
CLIPSJNI.Environment"
Note: the example in the README does not use the -Djava.library.path
option, it seems this is necessary for the OpenJDK runtime.
