Re: GraphStream help

[guilhelm savin <guilhelm.savin AT gmail.com>]

Hi Vladimir,

Welcome to our community.

Can you describe me how you generate your jar ?

A valid way to create a runnable jar, launching the

class "your.package.Main" of your Eclipse project

"MyGSProject", and using GraphStream should be :

1. Run "your.pacckage.Main" from Eclipse to create a

   launch configuration.

2. Go to "File > Export" and select "Java > Runnable Jar"

  2.1 Choose the launch configuration linked to your class

  2.2 Choose the output jar path

  2.3 Select "Extract required libraries into generated JAR"

  2.4 Click on "Finish"

This should create a valid jar. If not, check if gs-core 

is included in the build path of "MyGSProject".

Hope this helps. Tell me if not and if you need more help.

Regards.

Hi,

I am using your GraphStram Java library mainly for visualization network growth and is very helpful and pretty awesome...
but, I have one problem. I'm using eclipse and when I make a .jar file and run it from my terminal I get this error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/graphstream/graph/Graph
Caused by: java.lang.ClassNotFoundException: org.graphstream.graph.Graph
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: eccs2010.Tutorial1. Program will exit.

So, I don't now what is wrong but I would be very grateful if could you please help me to solve this or give me some tip. (also, I should menshon )

Thank you in advance!

Cheers

Vladimir
