I have installed the SneakPreview of Java SAP Web Application Server 6.40 (the SDN one from summer 2004). First web dynpro applications could be deployed, but since three days deployment failes. The error message is the same like in other threads:
com.sap.engine.deploy.manager.DeployManagerException: ERROR: Cannot connect to Host: [schlaeppi] with UserName: [Administrator] Check your Login Info. Exception is: com.sap.engine.services.jndi.persistent.exceptions.NoPermissionException: Exception during getInitialContext operation. Wrong security principles/credentials (message ID: com.sap.sdm.serverext.servertype.inqmy.extern.EngineApplOnlineDeployerImpl.performAction(DeploymentActionTypes).DMEXC)
I throught, it's the problem with the locked Administrator-User (Benny Schaich-Lebeks WebLog: How To Unlock Your Java Admin) but it isn't.
The licence test of the j2ee engine fails with "SAP Basis System: Operating system call recv failed (error no. 10054)", beause I installed SneakPrev in year 2007. Could these both errors be connected?
