Errors while trying to compile the "Original" Library Source code of JAVA 1.7.0 in eclipes

Question

sorry for bothering you all ..

I am trying to check out the SDK "Original" source code of sun java 1.7.0 (the src.zip file that come along with the complete package) in eclipse. I wanted to investigate the library src code for java.io.ObjectInputStream or java.util.ArrayList ....etc

But when I unzip the src.zip file and put it in Eclipse (under a new Java project) it shows me errors (attaching a snapshot of some errors ) ..Errors occurred during the compiling the source code lib

I am also attaching some of the errors screen shots ....... Errors in the code

Please pardon my ignorance and guide me to the correct path.

Many thanks

Regards

src.jar does only contain the source code of the public APIs and in certain places those delegate to 'internal' classes, e.g. com.sun.*.

If you want to look at the publicly available source code, you just have to install a JDK and point your Eclipse to the JDK instead of the JRE. Then it will automatically link to the source. Example screenshots reference IBM JDK (not JRE) 7 on Ubuntu.

EDIT: I forgot to mention that if you use OpenJDK via apt on Ubuntu (your screenshots look like this), you must explicitly install the source:

sudo apt-get install openjdk-6-source

Workspace preferences:

and source code for java.util.ArrayList

The icon on the editor tab indicates that this is just a link to the source file and not the source itself, you cannot edit it.
