SSL on Tomcat 4.0 with IBM JDK 1.3.0
I managed to start Tomcat 4.0.1 on my RH 7.0 box only after I replaced Sun's JDK 1.3.1 with IBM's JDK 1.3.0. This also avoids errors in some other packages (I'm experimenting with Velocity). So, if I want to have an SSL connection to TC 4.0.1 on IBM JDK 1.3.0, what do I need to do? Thank you all. -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]

Re: Problem with TOMCAT 3.3 : can't find tools.jar of my JDK 1.3.0
I had the same problem and here is what I found: I found where Tomcat is trying to add the tools.jar file. The line contains: System.getProperty( java.home ) + /../lib/tools.jar A println(java.home = + System.getProperty( java.home )) in a test program returns: java.home = /usr/bin/../opt/java130/bin/../jre jre was a link instead of a directory. This made the ../lib unpredictable. I moved the jre around and now it works. The jre link was made to install an fast jvm on the node.

Sun JDK 1.3.0 and multiple 'java' startups?
Greetings, I'm running Tomcat 3.1 with several virtual hosts, and with Sun's JDK1.2.2 I had no problems. However, I needed to upgrade to JDK1.3.0 for another package, and now when I start up Tomcat I'm getting about 11 instances of 'java' starting along with each virtual host. With 5 virtual hosts I've got over 50 java processes running, which I'd like to get rid of. Am I doing something to cause the extra processes to start, or is it a bug or what? Thanks DK -- 99 little bugs in the code, 99 bugs in the code, fix one bug, compile it again, 101 little bugs in the code.

Are using jdk1.3 for Linux? If so they aren't really processes, they're threads. It's just that in Linux with the ps command it lists each thread as a seperate processes. As far as I can tell, most of the memory is shared, so it really isn't using as many resources as it seems, hopefully. If you're not using Linux, just ignore me... Elijah Roberts [EMAIL PROTECTED]

Memory also seems to be massivly misreported, to the point where I once had tomcat aparently using nearly 400 MB of ram (I was load testing, so there were a lot of threads), which is 'somewhat unlikely' given I was on a laptop with 196MB of ram and 128MB of swap.

Yep. Interesting, someone ought to fix that. Indeed. It's one of those tough things where it's difficult to know whether it's actually wrong (Threads and processes in linux are very similar, and the processes *are* using that much ram, and it's not shared in the traditional sense) or not. I suspect in truth it's a bug in the 'ps' and 'top' utils, which should probably check if the processes are full processes or LWPs (threads). I'd look into it, but I'm an OO programmer, so the kernel scares me ;) Look at the amount of ram *free* on the server, if that is low, it might be worth upgrading it... So it looks like under normal circumstances I'm running pretty light on real memory, but next to nothing has been swapped out. I guess thats good? That's not *too* bad. Linux caches stuff. lots. If you've got a lot of ram free for a while, you'll end up with half your inode tables and blocks in ram. If your machine has lots in swap, it's time to worry. yours looks healthy. What VM are you running, out of interest - it's interesting that you save a fair bit of ram when you restart tomcat? If you're running a JIT/Hotspot compiler, it's almost certainly nothing to worry about (they learn what needs optimising and will eat ram to make things run faster, if necessary.)

[tomcat-user] Re: Sun JDK 1.3.0 and multiple 'java' startups?
okay.. memory usage now. 3 things to note. 1) What you see is not what is happening (under unix). Here is a good general guide (although written as reference for GNOME project): http://mail.gnome.org/pipermail/gnome-list/1999-September/031795.html 2) Java allocates memory for it's own purposes (ie: for being it's own cpu/os virtual thingy). It's default heap can be large, although it tends to be set small for x86 jvm's as vendors relieze that boxes average ~ 128mb, and you don't want to set it too big. 3) now java's heap: Imagine that you run your virtual CPU in software, and your virtual CPU get's swapped by the OS, then forget about any application running on the virtual CPU.. run : java -X see: -Xmssizeset initial Java heap size -Xmxsizeset maximum Java heap size These values are critical for good performance. If java process swaps you're in big trouble. I would think the OS needs to have hooks into userspace for the jvm to handle swapping gracefully... No one seems to mention this mess right now. Anycase, just fyi..
