Dialog box to choose workspace in eclipse

Inorder to enable popping of a Dialog box to select a workspace in an eclipse application,
browse to configuration\.settings under eclipse root directory and edit org.eclipse.ui.ide.prefs
Set attribute SHOW_WORKSPACE_SELECTION_DIALOG=true

Therez another way around to do this by editing the registry.
Would post about it some other time.

PATH and CLASSPATH

Keeping on the trend of finding the differences as in my earlier posts but importantly understanding them, herez the basic difference between the environment variables PATH and CLASSPATH :
PATH stores the location of executables where as CLASSPATH holds that of classes or jar files.
Hence, the common mistake of placing the bin directory inside CLASSPATH could be avoided by appropriately placing them in PATH variable.
