Unable to login Visual Administrator..

Hello Friends,

I have installed ECC 6.0(ABAP+JAVA SR2 SP9) on windows 2003 with Oracle 10g database.

1. I am unable to logon visual administration with j2ee_admin user. I think its locked.. I tried to unlock with sap* user. There also I am not able to unlock.

2. Now I have to configure java web dynpro. What r the basic steps for configure java web dynpro. My engine is sp9. Which netweaver developer studio I have to use. Please provide me download links.

3. Is there is any relation between j2ee_admin not logging and running java web dynpro. Can I run the java web dynpro without logging in to the visual administrator.

4. After installing NWDS how to connect the server from NWDS.

5. My system is standalone. It does not have SLD

Thanks

MS
