He says he is trying it from outside of the IDE.
@OP, you are obviously contradicting yourself when you say you know the basics of the classpath then talk about moving to the source directory. You also contradict yourself about those points when I ask you for the classpath, and you give me a package path style reference to a source file, then do the same thing when I ask after the full filepath of the actual class (not source file) to be loaded.
Now, provide me with the classpath you use to execute the command (if none, say none), and provide me with the full classname with package (class name not source file name), and provide me with the full filepath to the class to be loaded (full filepath). Also, provide me with the full filepath to the directory in which you find yourself when you execute the command, and provide the full and exact command you used to execute the command, and provide me with the full stacktrace, not your own generated error message.

Here I wanted the class name (e.g. au.com.allhomes.listing.harvester.harness.ListingTestHarnessConfiguration)

Compiled class filepath not the source file path, I couldn't, to tell you the truth, care less about the source file at this point, but I assume the above (where I wanted the classname) is it, and I will assume the classname I provided is correct.
C:\Harvester\build\classes\au\com\allhomes\listing\harvester •

Well, if you are executing directly from C:\, and not from C:\Harvester\build\classes\ (assuming '.' is in the System CLASSPATH), then of course it is ClassNotFound (depending on what the system classpath is). You should actually be getting a ClassNotFound on the "main" class.
and how the user vairable 'classpath' and the 'CLASSPATH' (its in capital, which i get to see often) from System variables list below it...?Plz explain me this too,even if its the out of scope of the post.

why not simply
and let the stacktrace print to STDERR. It's only to get the complete stacktrace, and you can, if you want, remove it later.Java Syntax (Toggle Plain Text)
Error: Cannot read the urlConfigFile [/Harvester/build/classes/sample/data/local
_url_map.properties]
java ListingTestHarness <options>
Where options include:
--inputHtml <htmlFile> The HTML file to parse.
--listingType <residentialSale | commercialSale | businessSale | ruralSale |
residentialRental | commercialRental>
--parserConfigImpl <parserConfigImpl> The parser configuration to use.
--parserClassImpl <parserClassImpl> [Optional]: The parser class to use.
--urlConfigFile <urlConfigFile> A mapping of remote URLs to local te
st resources.
--pageType <listingPage | searchPage> The type of HTML page being harvested. Also I noticed one thing with the netbeans behavour, which is very strange for me.
If I change the code, like the test/string inside
throw new IllegalArgumentException("Failed to load** parserConfigImpl [" + parserConfigurationClassName + "]: Class not found");
Like as u can see i put the ** in the string and compiled the project again.Now if i execute it from the cmd i cant see the change in the output exception i got.
what wrong with my concepts..??

'.' is the "current" directory symbol.
How to get the value of an environment variable is an OS question, but for Windows type "set CLASSPATH" (and it should be uppercase not lowercase).
As far as the error posted above, that is not one that has to do with the problem you say you've been having, and to solve that one does C:\Harvester\build\classes\sample\data\local exist? Is it locked? Do you have permission to it?

Thnx.Yes i had noticed this thing before.I used to get the exception cannot find the file local_url_propeties because i had moved the folder data for some experimenting purpose.
And when i realize this i kept it back.Now I had did it again and resolved with that prev error.
The error I am facing now is this exception I am talking about -
au.com.allhomes.listing.harvester.parse.
RealEstateCoParserConfiguration is my implementation of the
interface which I need to pass as a 'parserConfigImpl' parameter to the cmd.
But it throws the exception classNotFound..??
sorry if i confused u between these both errors.
