[nfbcs] Java and Eclipse Problem

[Currin, Kevin]

Hello All,

I would like to thank all of you for your help with this issue. I found a solution that involved going to eclipse.ini and adding the following line:
-vm <path_to_the_java_executable> C:\Program Files\Java\jdk-1.7.0_11

Eclipse is back running now.

On another note, do any other jaws 12 users have any problems with eclipse frequently freezing and acting glitchy?

I have this problem when editing a class file and when trying to navigate between projects and to the console.

Thanks,

Kevin

In your computer system settings, you must do the following:
1. Set the path and java_home so it includes the "bin" directory of your
java install.
On my computer, I have the following entry:
Control Panel => System and Security => System => Advanced System Settings
=> Environment Variables
This takes you to the Environment Variables dialog
There, go to System variables section and update the following:
A. JAVA_HOME - make sure this points at something like: => C:\Program Files
(x86)\Java\jre1.5.0\bin
This should point at the bin directory of the Java version you installed.
That's where mine points to - and take note it points to the bin directory
B. Then make sure your PATH statement includes the same directory.
It must be separated from other folder paths by a semicolon.

Then in your Eclipse projects, the Project menu => Properties menu item
Make sure you configure Eclipse so it points at the JRE you are using.

Compiling applications
If your project => properties is configured correctly, Eclipse should be
able to compile your applications correctly.

Compiling your applications at the command line
If your environment/path points at the proper bin directory, then when you
go to a command line to run your application, javac should be known by the
sytem.

Keep in mind when compiling or running, make sure your classpath is set so
that Java knows where all of the classes you are using are located.
If all you're using is pre-built classes in the Java JRE you've configured,
the classpath isn't really necessary.
But, if you've compiled some other java classes and want to use them, your
classpath statement must include the folders where your other classes are
located.

This is rather lengthly, but it should help.

Hello,

I recently downloaded Java version 1.7 update 11 and Eclipse for a
programming class I just started. At first, everything worked out ok; I
could use Eclipse to generate basic java programs. Then I tried using the
windows command line to run java scripts. I ran into a problem with the
command line not recognizing javac, so I followed the following online
instructions to try and fix this:
1. Go to control pannel
2. click system and advanced system settings 3. go to environment variables
4. go to system variables 5. prepend certain directory to path

The problem is that this did not help with the command line and it also
caused Eclipse to stop recognizing java. When I try to use eclipse now, I
get a message saying that java is needed and that eclipse cannot find it in
a given directory. I've tried uninstalling both eclipse and java and
reinstalling and have tried messing with directories and paths.

Does anyone have any idea what I can do to restore the path that allowed
eclipse and java to work together?

Thanks,

Kevin
