patchset upgrade from 10.2.0.1 to 10.2.0.5

hi guys,

i am having a 10.2.0.1 db and want to upgrade it to 10.2.0.5 .

following are components present in 10.2.0.1

COMP_NAME STATUS
---------------------------------------- -----------
Oracle Database Catalog Views VALID
Oracle Database Packages and Types VALID
JServer JAVA Virtual Machine VALID

My query is how do i go ahead with the component "JServer JAVA Virtual Machine " .

two way i have thought
1) create a new home 10205 by installing binaries 10.2.0.1 and then apply patachset 10.2.0.5 (how do i go ahead with component JServer JAVA Virtual Machine )
2) if i am applying patchset 10.2.0.5 on existing home (how do i go ahead with component JServer JAVA Virtual Machine )

Any document id or steps will be greatly helpful.

just run the updater in your existing home and everything will get updated

you mean to say in existing 10.2.0.1 i should apply 10.2.0.5 patchset that it's nothing else , if no then please be specific

correct
