View Full Version : [SOLVED] eclipse cant edit .java files?

February 22nd, 2010, 01:33 PM
I installed both eclipse and java runtime through the software center. It opens and I can load my windows workspace fine. But the workspace only shows .class files. There also no option to create a .java files.
Even after creating my own workspace I cant create any .java source files or open the editor.

You need the jdk (java development kit). Funny that synaptic did not install that along with eclipse. You can use eclipse to develop non java applications so I guess the jre (java runtime environment) is enough.

The package name is default-jdk

I installed the jdk, but everytime I open a .java file in eclipse (from the pacakge explorer), it just opens a text editor window (gedit), not the editor for java source files within eclipse.

The most I can do is open the .java files with the eclipse text editor, but that doesnt allow me to run or edit them.

Is there anything under:

Help > Software Updates > Find and Install...

In eclipse? I haven't used it in ages and don't have it installed on ubuntu right now but I think from eclipse you can just about install any plugin you need. But usually it comes with the java already installed, don't know how the ubuntu ppl packaged it but by the looks of it it doesn't make sense.

no, there are no updates, its a new install so there should't be.

Ubuntu is not fit for programmers, there is not a good package availeble for eclipse. It is best to uninstall and re-install it manually:

it might be that nautilus is currently binded to using a text editor when .java files are opened... try right clicking the java file, the Properties, then Open With,,,and select or explore Eclipse there...

This was true for a long time. I thought Eclipse had recently been updated to the current version (3.5?).

@erjoalgo: Did you install the eclipse-jdt (Java Development Toolkit) package?
