Blogging is so 2005

An interesting excerpt from this article – wonder why I never thought about it. Maybe the sheer idea of death is so remotely connected with the digital age.  I have never heard of anyone die while coding, debugging,designing,testing, blogging, chatting online, etc.  

“As has always happened as the internet has developed, the technology creates new situations that legal systems haven’t anticipated such as bequeathing digital assets. When you die, who gets your passwords?”

Trouble Debugging in Eclipse? “Source Not found”

I found the solution to this problem finally…must admit that its one of those that appear “silly”  after you know what you missed!

So instead of beating about the bush, here’s what you do to hit the nail on the head –

Problem:

com.mymainclass at localhost:4773
Thread [main] (Suspended (exception ClassNotFoundException))
ClassLoader.findBootstrapClass(String) line: not available [native method]
Launcher$ExtClassLoader(ClassLoader).findBootstrapClass0(String) line: 891
Launcher$ExtClassLoader(ClassLoader).loadClass(String, boolean) line: 301
Launcher$AppClassLoader(ClassLoader).loadClass(String, boolean) line: 299
Launcher$AppClassLoader.loadClass(String, boolean) line: 268
Launcher$AppClassLoader(ClassLoader).loadClass(String) line: 251
Launcher$AppClassLoader(ClassLoader).loadClassInternal(String) line: 319
 
Solution:
"I had the exact same problem when I first installed eclipse.
Since I had specified the JRE Path under
"Window->Preferences->Java->Installed JREs",
Eclipse couldnt locate the JDK.
Install JDK.
Go to Window->Preferences->Java->Installed JRE.
Click on "Add" Button.
Click on the "Browse" button Next to the "JRE Home Directory"
and specify the JDK Home.
Add JDK's path as JRE Home. In my case it was D:\Java\jdk1.5.0_02

There you go! Happy debugging!!!
