figure it out (thrugh my toturial I downloaded from the net).
Then I must have done something wrong becuse there came this messege on
every file I had developed (also the files that worked before):
"Incompatible .class files version in required binaries. Project 'Breve'
is targeting a 1.2 runtime, but is compiled against 'C:Documents and
Settings/Daniel W.
Petersen/Skrivebord/Fag/java/J2sdk/jre/lib/charsets.jar' which requires a
1.4 runtime."
I have search for the error In about a month now (FAQ, toturials and so
on), and I have reInstalled all that have a little to do with Java (and
this time I only Installed J2sdk (becuse I have got brighter thrugh the
toturial I had downloaded), but the problem still were there.
After I had got dowloaded and instaled the J2SDK the comand prompt reacted
when i wrot Java, but the tutorial menu (that are programmed in Java)
did'nt work, the tutorial are in HTML.
What have I done wrong, some sugestions?
PS: If there are some poits there are difficult to read then please
say/write it, becuse english are not my native language.

It's saying you do not have the correct JDK..
Do you know the versions of JDK and J2SDK you installed.. You need to
install the 1.4 or better yet 1.5 JDK.
I would uninstall what you installed the JDK/J2SDK and download JDK 5.0
Update 5, JRE 5.0 Update 5 and J2SE 5.0 Documentation from here
http://java.sun.com/j2se/1.5.0/download.jsp
After that load Eclipse and do the following..
- At the top, select 'Preferences'
- Select 'Java'
- Select 'Installed JREs'
- Then add the location of the JRE 5.0 you just installed.
The documentation you usually unzip into your JDK folder. The will
create a \docs folder with all of the api information.

You may want to select your project and then select 'Build Project' just
in case old class files are still around.

I have done as you said, but it still don't work.
Then I reebooted the system and searched all Eclipse for the Error I have
made.
I reemembered to change my environmentvaribles. It works on the command
prompt (I run on Win XP proofecional service pack 2) and wrote Java, then
there came the list of commands, and the Java menu in my toturial works
again (see above).
THere are only one change in Eclipse, and thats the Error messege:
"Incompatible .class files version in required binaries. Project
'Boghandel' is targeting a 1.4 runtime, but is compiled against
'C:Programmer/Java/jdk1.5.0_06/jre/lib/jsse.jar' which requires a 1.5
runtime"
