Hello all!

I have a problem with GAE.

Even simpliest 'helloworld' app doesn't work in Eclipse.

Such error appears:

java.lang.IllegalStateException: SecurityManagerInstaller must be loaded in the system ClassLoader; was sun.misc.Launcher$ExtClassLoader@35ce36
at com.google.apphosting.utils.security.SecurityManagerInstaller.generatePolicyFile(SecurityManagerInstaller.java:103)

at com.google.appengine.tools.development.DevAppServerMain.<init>(DevAppServerMain.java:113)
at com.google.appengine.tools.development.DevAppServerMain.main(DevAppServerMain.java:89)

What does it mean, any idea, please?:)
