Eclipse IDE for C/C++ Linux Developers CANNOT run my java application

I installed Eclipse IDE for C/C++ Linux Developers to write some cpp codes. As I understood it, no matter which version of Eclipse I use, it always can be used to writing some java source codes.

I did this:

• File->New>Java Project->...
• Wrote a simple "hello world". I have confidence that my hello world is correct.
• When I wrote my code, Everything went well.
• But when I right clicked my new project, I found there was no "Run as","Debug as"
• Press Ctrl+F11. It said "the selection cannot be launched, and there are no recent launches"
• Run->Run Configurations. I double clicked Java Application. It said "No tab group defined for launch configuration type org.eclipse.jdt.launching.localJavaApplication"

How can I run my java applications?

Quite contrary to what you assume, eclipse isn't a Java IDE with some other addons. Eclipse is just a platform. As the package comparison shows, the C/C++ package doesn't come with the Java development tools.

Make sure you have correct eclipse version is downloaded? There will be separate eclipse version available for Eclipse for java. http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/indigor

Hope this help.

If you have the JDT installed, then make sure you are in the Java perspective. Either:

• Window->Open Perspective->Java (default)
• Use the perspective switching tab, usually the top-right of your code editor

You can install the JDT, if you don't have it by using:

• Help->Install New Software...

Try to install follow this link http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/indigor if it's work. i think your eclipsec/c++ may be have a problems while install java. You can reinstall or using eclipse for java.
