I am trying to use the gv_java – graph manipulation using java with Graphviz.
I downloaded the java package which contains the SWIG Type files in java.Installed graphviz as required.
For a cleaner solution I tried using the JNI provided by graphviz and Here is my test code.

The system is able to load the library,but when I call the native methods I get UnsatisfiedLinkError in the line of method call without any message.
Am I doing anything wrong.I have installed graphviz in the linux machine,the libraries and all the classes are in position.
I checked the installation and everything is proper so I decided that something is wrong with my java files.
I read various posts on the naming convention while using
JNImethods,since forGraphvizall the java method names are generated bySWIGthe next thing I checked was the package structure.In my code above I initially had all the
GraphViznative methods in my own package name rather thanorg.graphviz(as provided by them).I moved them to the respective packages and it worked like a charm!
