Delete JAVA Stack in system with ABAP+JAVA

Question

Hello,
A few days ago I installed a SAP ERP 6.0 SR3 with both stack: ABAP+JAVA.
But now due some things, I want to know if it is possible to delete the JAVA stack! Yesterday I did a search how to do this, how it is possible to do this, and I found a document/presentation "SAP NetWeaver 7.0 - Deinstalling Java Add-In" on the following link:
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/608b079f-d0f2-2c10-62ac-a00f1b6d536f
The database of this system is a MS SQL Server 2008 (R2) and the operation system a Windows Server 2008... and as you can read in this document, it is more focused on Oracle databases, so I would ask you if this document is correct (it is official?) and if it is possible to do this in SQL Server environment, and if you know which are the manuals post installation activities for SQL Server, because all that manual post installation steps in this document is for Oracle DB!
Thank you in advance.
Kind regards,

Hello Subhash.Chandra
I did the deinstallation of SAP Java Add-In, for this I followed that document which I described above. After deinstallation through sapinst, I also eliminated some directories as it is mentioned in that document, like the following directories:
DIR_GLOBAL\security\data
DIR_INSTANCE\SDM
DIR_INSTANCE\j2ee
I also delete all Java parameters in default and instance profile (like j2ee*).
So, after all, I started the ABAP instance... the system was starts, but I unfortunately the SAP MMC console show a yellow semaphore which is related with a problem disp+work.EXE, it have the following status:
Running, Message Server connection ok, Dialog Queue time: 0.00 sec, J2EE status info unavailable.
I already restarted the sap system but even so that error is shown!
I checked the dev_disp:
