[SOLVED] Fastest algorithm for beginners

[yannis]

Still doesn't work:

Code: Select all

/usr/local/java/bin/java -cp "lib/gephi-toolkit.jar;." -Xms128m -Xmx260000m graphlayout.Main
Exception in thread "main" java.lang.NoClassDefFoundError: graphlayout/Main

	at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: graphlayout.Main.  Program will exit.

The graphlayout/Main.class file is there indeed:

Code: Select all

ls -l graphlayout/
total 8
-rw-r--r-- 1 yannis users 3657 Dec 30 00:04 Main.class
-rw-r--r-- 1 yannis users 3216 Dec 29 23:37 Main.java

Did you make sure to change directory to graphlayout and execute the script from there with just ./run.sh?
I tried it in windows with cygwin.

It works now! The error was that in Linux environment variables, directories are separated by colons and not by semicolons. Thank you very much again and happy news year's eve!

[eduramiba]

Cool
You are welcome, happy new year to you too.

It worked fine!

Now I have another problem, I don't know if I should continue this discussion or start a new one.

I use Chinese characters in the label of my graph, using font SimSun. They display fine in gephi's interface but the font is not exported in the PDF file (so that my graph in the PDF file is completely empty of labels). The only font included in the PDF file is Helvetica.

How can I embed fonts in the PDF files produced by gephi?

Thanks in advance

Hi,

Please create a bug report on GitHub

I can compile your example code (graphlayout.zip) but when I execute ./run.sh I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: graphlayout/Main
Caused by: java.lang.ClassNotFoundException: graphlayout.Main

Any hint?

Hey assaraf,

The answer is above: if you're running the script on Linux (or Terminal in Mac OS X) you need to replace the semicolon with a colon. So you should run:

Code: Select all

java -cp "lib/gephi-toolkit.jar:." graphlayout.Main

Worked for me even though I had the same error as you...
