WC 10.1 need to upgrade Java to 6-39 and apache to 2.2.23 but NOT WC itself

Hello,

we are running WC 10.1 M010 - in order to comply with our security requirements, I need to upgrade my windchill servers to java 6 update 39 (the PSI installed java 6-37)

Also, I need to update apache to 2.2.23 (PSI installed 2.2.22)

I do NOT need to upgrade windchill itself (we will stay at 10.1 M010)

in broad strokes, could someone fill me in on the general approach to how to do this, or what PTC document I should be reading?

thanks!
