Thank you for your quick answer.
I don't know how the part of this path got lost (i haven't changed anything) i will try it when i am back home. But i had the same issue with some other projects, it works once and then no more, and i haven't changed anything on the path, could this be a bug?
And second of all, currently im not at home, but i tried to run lamw on my macbook. As it works fine with Linux, and the Crosscompilers, ndk, sdk and ant are working fine with OS X, so i thought ill give it a trail. But i found a huge problem with it, i could install the packages, but when i try to enter the path config window (Tools->[LAMW] ... -> ...), it crashes. Is there any possibility to fill the data by hand (in a config file or something)? I'd like to check out if it works with OS X too.
Edit: Solved the OS X problem by replacing the RadioGroup with a Combobox. But with OS X it also cut's the Path off (New Project -> JNI GUI, then Project Settings->Paths the i386-darwin is missing), so it seems that this might be a bug within LAMW
