<P><FONT SIZE=2>First of all I got the mod_jk thing taking care of. Thanks for the help.</FONT>
</P>
<P><FONT SIZE=2>As for the memory thing I am judging what is going on by using top. I have a total of about 320mb of RAM (2 128mb sticks and 1 64mb stick). When I first boot my system a total of about 100mb of that memory is being used. I log into the GUI and that bumps it up to around 120mb. I play around with a few apps for a couple of hours. As I would suspect would happen, I open an app and it takes up a few mb of memory. As soon as I close that app the memory is released. I do this with a few apps and then when the method stays the same I open OpenOffice and it takes up it's 115mb. However when I close it the memory that it was using does not free up and that is a lot of memory to not get freed. Then, for testing purposes, I reopened it and BAM, there goes another 115mb and now my swap partition is being used and I hate that cuz my little ol' pIII 450 starts to creep. Maybe I am badly misinformed but I was always under the impression that when an app starts it is supposed to request a certain amount of memory space and even request some while it is running but then, when it closes, it is supposed to notify the system that that space it "borrowed" is again available. Again, I am using top to judge all of this. Is there another tool that might be better?</FONT></P>

<BR><FONT SIZE=2>></FONT>
<BR><FONT SIZE=2>How are you mesuring the memory loss? Could be that there is some kind </FONT>
<BR><FONT SIZE=2>leak... but would</FONT>
<BR><FONT SIZE=2>be interesting to see if the memory is associated with a process or if </FONT>
<BR><FONT SIZE=2>it's the kernel.</FONT>
</P>
<P><FONT SIZE=2>> Second question. I am trying to configure Jakarta Tomcat and the </FONT>
<BR><FONT SIZE=2>> Apache webserver to work together by using mod_jk but I cannot figure </FONT>
<BR><FONT SIZE=2>> out where to get mod_jk. Can someone give me some hints on where to </FONT>
<BR><FONT SIZE=2>> get mod_jk and a few tips on how to install it?</FONT>
<BR><FONT SIZE=2>></FONT>
<BR><FONT SIZE=2>Look in the source for tomcat (something like src/native/apache...). </FONT>
<BR><FONT SIZE=2> Building is not particularly trivial.</FONT>
<BR><FONT SIZE=2>Things may have changed quite a bit for version 4 also (there's now the </FONT>
<BR><FONT SIZE=2>webapp method vs. using mod_jk...</FONT>
<BR><FONT SIZE=2>though I hear that mod_jk works for more folks than does webapp).</FONT>
</P>
<P><FONT SIZE=2>There is some documentation on the apache jakarta website, but sometimes </FONT>
<BR><FONT SIZE=2>it's not in the most</FONT>
<BR><FONT SIZE=2>intutitive places (they have a search pane though).</FONT>
</P>
