Hi All,

I was wondering if someone can give me a pointer as to how I should append a path to the JNI java.library.path in MyEclipse 7.0 on Linux so it is effective at startup.

The MyEclipse default value for the java.library.path does not seem to include /usr/lib, which contains the necessary *.so files to allow my user-installed Subclipse plugin to work using the JavaHL (JNI) interface.

I have added the following line to the myeclipse.ini file

-Djava.library.path=/usr/lib

This works in that Subclipse now works correctly. The only issue is that I am not sure if this appends to the default java.library.path used by MyEclipse or if it replaces it. If it replaces the default value for MyEclipse it is possible that some MyEclipse functionality that uses JNI could be broken.

Any thoughts or suggestions?

Best regards,

-J

J,

MyEclipse does not instrument or overload the java.library.path in any fashion that I know of. One of the developers may correct me on this 🙂 So I think you will be ok from MyEclipse standpoint to set the java.library.path in just the fashion that you have.

I added the following to my file but it doesn’t seem to pick up the JavaHL, reverts to no JavaHL found or I have to use the SVNKit

Ubuntu 8.10 64bit
Used All in One Installer
Added to the last line in myeclipse.ini
-Djava.library.path=/home/gcstang/svnsetup/lib

Thank you,

I’m not familiar with JavaHL or what it takes to make that work. Can you do MYEclipse > installation summary and post the details here? That will show the vm parameters and see if the -D property is actually getting set.

Looks like the -D isn’t getting added at the correct location.

Can you post the content of your myeclipse.ini file?

I also had it on my shortcut, but I removed that and now it doesn’t show in the Installation data I posted above at all.
I did leave it in my myeclipse.ini though.

The file I’m modifying is here : /home/gcstang/Genuitec/MyEclipse 7.0/myeclipse.ini

Thank you,
