cannot load J2EE Server

Hello,

I have installed the SAP ERP 2005 : ECC 6.0 with the both Java and ABAP Application Server.

But I have now a problem with the disp+work.exe still yellow.

In the J2EE process Table, the dispatcher and server0 have the statut "Starting Framework".

In the std_server0.out file, I have this :

SAP J2EE Engine Version 7.00 PatchLevel is starting...

Loading: LogManager ... 1969 ms.

Loading: PoolManager ... 15 ms.

Loading: ApplicationThreadManager ... 266 ms.

Loading: ThreadManager ... 62 ms.

Loading: IpVerificationManager ... 63 ms.

Loading: ClassLoaderManager ... 62 ms.

Loading: ClusterManager ... 844 ms.

Loading: LockingManager ...

The server cannot load the LockingManager !

What can I do ?

Regards,

Mathieu
