Eclipse did not install AppletViewer

[Bill Richardson]

Binary package hint: eclipse

I tried to run the Hello World program and got the following message

Exception in thread "main" java.lang.NoClassDefFoundError: sun.applet.AppletViewer
   at gnu.java.lang.MainThread.run(libgcj.so.90)
Caused by: java.lang.ClassNotFoundException: sun.applet.AppletViewer not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:/home/richardson/workspace/Project1/], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}

   at java.lang.ClassLoader.loadClass(libgcj.so.90)
   at gnu.java.lang.MainThread.run(libgcj.so.90)

I then uninstalled eclipse and tried to install it again and the install failed and I cannot uninstall eclipse--even from the command line. When trying to uninstall the following occured

eclipse only installs dependencies which are required to run eclipse. It doesn't install build dependencies for programs which you develop.

Hi All,
     I am experiancing similar problem. In my case I am installing Ilog ceplex and planning to use the JAVA concert technology. so whe I compile the java file (name: LPex1.java) I have no problem but when I try to run it I got the following message

eman@eman-laptop:~$ java -Djava.library.path=/usr/local/ilog/cplex90/bin/i86_linux2_glibc2.3_gcc3.2 LPex1
Exception in thread "main" java.lang.NoClassDefFoundError: LPex1

   at gnu.java.lang.MainThread.run(libgcj.so.90)

Notice that I am specifying the LD_library Path in the java command line!

I was serching on the net and I found alot of similar bugs for different types of lib files and one suggestion was to download the JDK od SUN which I wasn't sure if it would be the solution of my problem.

Please help if you know the solution.

Your problem is unrelated to eclipse. Your problem is probably that you
do not add any jars or folders to your classpath. You are most likely
missing a "-cp $jar1:$jar2:...:$jarN" in your command besides the
-Djava.library.path

~Niels

[Eme (eman76)]

When I compile I added the .jar path by the comand:

javac -classpath <path to .jar> LPex1.java

this command works with no errors, but when I write the following command:

java -Djava.library.path=<path_to_shared_library> LPex1

I got the error message that I posted earlied. I think there is a permission problem where the library can not be accessed by the user account! but since I am new to the linux os I don't really know how to solve it!

Hi Eme

You need the same classpath when you compile and when you run it. Try

java -classpath <path to .jar>\
-Djava.library.path=3D<path_to_shared_library> LPex1

Your problem is that java cannot find your class "LPex1". When running a
java class from cmdline you have to give it the full class name
including package (e.g. my.code.LPex1 if it is in the package "my.code")
as well as making sure that the class is defined in the classpath.

I do not know how you have concluded this problem is in eclipse; but
nothing so far connects your problem with eclipse. - particularly the
paths you have shown so far suggests that it is locally installed
software and not something provided by Ubuntu.

Hi Niels, thanks for your help but I guess it doesn't work. I tried the command that you gave me and this is what I got:

eman@eman-laptop:~$ java -classpath /usr/local/ilog/cplex90/lib/cplex.jar\ -Djava.library.path=3D /usr/local/ilog/cplex90/lib/i86_linux2_glibc2.3_gcc3.2 LPex1Exception in thread "main" java.lang.NoClassDefFoundError: .usr.local.ilog.cplex90.lib.i86_linux2_glibc2.3_gcc3.2

Caused by: java.lang.ClassNotFoundException: .usr.local.ilog.cplex90.lib.i86_linux2_glibc2.3_gcc3.2 not found in gnu.gcj.runtime.SystemClassLoader{urls=[], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}

   at java.lang.ClassLoader.loadClass(libgcj.so.90)
   at gnu.java.lang.MainThread.run(libgcj.so.90)

I think I am missing up things so I will give you what I have done:

The LPex1.java under my home directory

the ilog folder is under the /usr/local folder which has the .jar file in the library at the mintioned path

they are in different directories so if I want to run the LPex1 should I save it under the /usr/local directory!

the following was the way that I got from the ilogcplex tutorial to run java:

eman@eman-laptop:~$ javac -classpath /usr/local/ilog/cplex90/lib/cplex.jar LPex1.java
eman@eman-laptop:~$ java -Djava.library.path=/usr/local/ilog/cplex90/bin/i86_linux2_glibc2.3_gcc3.2 LPex1Exception in thread "main" java.lang.NoClassDefFoundError: LPex1
