I note Java 1.6.0 has been updated to 1.6.0-33 with a large amount of security fixes added.
http://www.pclinuxos.com/forum/index.php/topic,106251.0.htmlThat Software Announcement was written on 13 June 2012.
keep checking Synaptic, but I still have v.1.6.0.31-1pclos2012 installed, and available.
This is obviously a synching of the servers that make up our repositories, so I'll just have to be patient. 
I've tried all my locale Repositories, but generally use #ttp://ftp.heanet.ie/pub/pclinuxos/apt/ as it seems to be the one that Synchs the quickest.
There have been a steady flow of updates over the last three to four days, which is good; thanks to all those working to update packages as it's noticeable in the performance of my Computer these are needed and quality upgrades.
Because the Java update is a
Security issue I Visited:
How do I download and install 32-bit Java for Linux Platforms? The penny dropped that their instructions would not work due to locations being different for the location of our Java installation, plus I've read all the warnings about installing a package from outside of Synaptic.
I would have thought something such as a Java update '.rpm' would be universal however, especially as it's so widely used.
I guess I wait for Java to appear in Synaptic;
or is it possible to download it from Sun and install manually, using a command specific to PCLinuxOS, seeing this is a security issue ?
The recommended version I see here:
Java Downloads for Linux is ;
JRE 7 Update 5 - linux.rpm.
I couldn't install that anyway, from their instructions, and it's version number doesn't make any sense.
Advice anyone ?
I suspect I'll have to wait for the Repos to Synch.

Thanks for taking the time to consider this question,
