Sorry, the freenet.jar in the snapshots dir was corrupt (see
http://article.gmane.org/gmane.network.freenet.support/6602). Toad will probably
have fixed it by the time you read this, download
http://freenetproject.org/snapshots/freenet.jar over the top of your existing
freenet.jar and try it again.

Hello,

Same errors ...

Yeah, do this instead. I wrongly thought that freenet-ext.jar got explicitly
loaded by freenet.jar if it existed.

Well ... the version of Java generally speaking shouldn't be a problem as long
as it's recent (1.4.1 isn't generally recommended.) There was a recent issue
with the bundled webinstaller using an old java, but many people successfully
run freenet with Java 5.0.

Also there is a file "Flaunch.ini" written by the installer on setup into the
main directory, that tells freenet where java is. If you change your version of
Java after it's installed you may need to edit this file to point at the new one
(or reinstall freenet in which case the installer should do it for you.) It
looks something like this : 

 [Freenet Launcher]
 JavaExec=C:\Program Files\Java\j2re1.5.0_04\bin\java.exe
 Javaw=C:\Program Files\Java\j2re1.5.0_04\bin\javaw.exe
 JavaMem=default
 Priority=0
 PriorityClass=64

If it's currently wrong search for "java.exe" and "javaw.exe" and update the
JavaExec / Javaw lines as appropriate.

Basically this error implies that Java *is working* but it can't find the class
to run in freenet.jar for some reason. So either that class isn't in the jar
(which is why I suggested a corrupt jar), or it is but it can't even find
freenet.jar .

Did you download the jars manually? If so, where - are you sure you put them in
the right place?

Some stuff you can try :

1. Open a command prompt (cmd.exe on NT/w2k/XP, command.com on 9x)
2. Type "java -version", you should get some java info. If so Java is working.
3. Search for freenet.jar and note where it is
4. Check that freenet-ext.jar is in the same directory
5. Change to the directory where freenet.jar is in the command prompt. (A quick
way to do this on NT/w2k/XP : select the whole path in explorer's address bar,
ctrl-c to copy it, type [cd "] without the brackets, right click on the command
prompt to paste it, type another " and return.)
6. Enter "java -Xmx128M -cp freenet.jar freenet.node.Main" without the quotes.
Hopefully this should start freenet after a while, although because you're not
doing it the official windows way you won't get the systray bunny etcetera. You
should be able to tell if it's working if you don't get any error messages and
your freenet.log file starts growing, and eventually by being able to open
http://127.0.0.1:8888 .

Hope that helps,
Bob

Bob,
Thanks for gettiing back to me. I have re-downloaded all .jar files but it 
fails after it downloads freenet.exe. Once it executes freenet.exe to create 
default.ini, it fails at mergeconfig command. THat is where I get the "Could 
not find the main class" error.
Thanks

Jim

Hmm, odd. The most likely cause is a corrupt freenet.jar, try comparing the
sizes / re-downloading it. Or you are trying to use 0.7's alpha jar which 
IIRC
has a different main class, but this would be hard to do by accident since 
they

aren't even hosted on freenetproject.org :)

Failing that, what does the end of freenet.log say when this happens?
