java.lang.NoClassDefFoundError: com/jogamp/common/type/WriteCloneable jogl 2 in eclipse

问题

I am on windows 7 64 bit and using eclipse indigo. I downloaded the latest version of jogl 2 and i have created an eclipse project following this link

https://sites.google.com/site/justinscsstuff/jogl-tutorial-2

this tutorial is old as the jars in the jogl download dont match and i have included all the jars and for each jar set the native libraries directory. I have written a small jogl test program that creates a GLProfile, GlCapabilities and an awt frame. I get this exception:

Exception in thread "main"

seems like im missing a jar..could any let me know what im doing wrong here?

回答1:

I am using the jogl-all.jar from Matlab 2014a. The error above disappeared and everything run smoothly when I added the library glugen-rt.jar.

(remember also to -Djava.library.path=/path/to/native/files when you execute your application, in my case this was -Djava.library.path=/Applications/MATLAB_R2014a.app/bin/maci64)

回答2:

Try to add gluegen as well.

For example

<dependency>
    <groupId>org.jogamp.jogl</groupId>
    <artifactId>jogl-all</artifactId>
    <version>2.0-rc11</version>
</dependency>

AND

<dependency>
    <groupId>org.jogamp.gluegen</groupId>
    <artifactId>gluegen-rt-main</artifactId>
    <version>2.0-rc11</version>
</dependency>

回答3:

I had a similar problem with the JOGL jar files. See here. Also, check out the tutorials on the jogamp wiki (by the looks of it Wade is pretty active on the wiki).

回答4:

i checked the link you gave and it seems like they had changed the structure after that tutorial was made. In any case, i download the march 2011 binaries and it works fine..
