RE: JK2 crashes IIS
After I uninstall and re-install IIS, the problem is fixed. Here is another hint from a Tomcat user: == You've already enabled full debugging for the log which is a good start. My log info was exactly the same, although in my case only the ISAPI filter crashed rather than all of IIS (in reality, I think the ISAPI filter was forced to unload by IIS/Windows, but the effect is the same). A restart of IIS would reload the ISAPI fine. It would then examine/log every incoming request until a match was found, indicating that the request should be redirected; at this point it would crash. I felt that this was a permissions issue; either the DLL was not allowed to execute correctly, or a new socket could not be created. Using Windows Audit Object Access could identify the denial, but potentially auditing would have to be enabled for multiple folders. Rather than turn Auditing on for numerous folders, what we did was to use FileMon, a very useful utility from SysInternals: http://www.sysinternals.com/ntw2k/source/filemon.shtml With FileMon running in the background, I restarted IIS and checked that the isapi_redirect.log started to grow. I then accessed a URL which caused (as expected) the ISAPI to unload. FileMon pinpointed the file to which access was being denied - and after all this time, it was the isapi_redirect.dll !!! We then enabled Auditing on this DLL and repeated the test; this told us which NT user was being denied access (FileMon doesn't include this level of detail). The NT permissions on the DLL were correct, but IIS had both Anonymous and Integrated Windows authentication (aka NTLM) access enabled. The NT authentication was correct, but IIS was trying Anonymous first, which was causing the ISAPI to unload. By simply disabling Anonymous, so that only Integrated was enabled, the ISAPI started working. One little tick box... Whilst your problem may not be exactly the same, I think some change has occurred in your set up to upset the permissions. This may be due to a patch from Microsoft, or some extra security (eg. URLScan), or just a minor change in IIS which has had some unexpected results. = -Original Message- From: Hua Hou Sent: Friday, November 19, 2004 5:44 PM To: Tomcat Users List Subject: JK2 crashes IIS I have been using IIS 5.1 with JK2 for more than 18 months.

Euro sign and Trademark sign not displaying properly
All, I am using Tomcat 4.1.24 and Oracle 10g on Windows XP environment. I am facing a problem that euro sign and trade mark can not be displayed properly on the web browser. These euro sign and trademark signs are read from Oracle using JDBC java code. But when I display them on the web browser, I saw ? rather than the actual sign. When I dig deep into the problem, I found that after I read those signs from Oracle with Oracle JDBC thin driver, the HEX code for those signs are 3F, rather than 80 or 99 (for euro or for trademark sign respectively). When I was using SQL server before, all those signs were read and displayed properly. I have searched the Tomcat mailing list and the internet extensively, but have not found any solution. Any ideas? Thanks. Hua

jsp:include and case problem
I am having a case problem with jsp:include. I am using Tomcat 4.1.24. Here is the problem: 2 jsp: A.jsp, b.jsp Inside b.jsp, I have jsp:include page=a.jsp/ In the browser, when I invoke b.jsp, A.jsp is compiled into a_jsp.java and a_jsp.class. My understanding is that jsp is case sensitive, which means A.jsp should never be compiled into a_jsp.java and a_jsp.class, instead, Tomcat should give 404 error. Is there way to prevent Tomcat from compiling A.jsp into a_jsp.java when A.jsp is included using jsp:include? Thank you for your great help! Hua

However, I have two problems with this log file: (1) I added -verbose:gc option as the JVM option when install the Windows service, however, no GC info is logged in this file.

RE: Tomcat Memory leaks!

RE: -Xincgc, -Xms600, -Xmx600
I was experiencing similar problem with Tomcat 4.1.24 + JDK1.4.1_02. When turning on -verbose:gc, I found that when the memory usage reaches the -Xmx setting, Full GC will kick in and try to claim the unused memory back. However, because of the JDK1.4.1_02 memory leak bug, the Full GC keeps running for 200 cycles (continuously) (which hangs the whole system for quite some time) and eventually I got Out-of-Memory error. My fix to this problem was to replace the setLength() method in StringBuffer (JDK1.4.1_02) with the setLength() method in JDK1.3.1_07 version and place the customized StringBuffer.class file under Tomcat-Home\common\endorsed directory and now the problem goes away.

RE: Tomcat STILL freezing - time to look at another app server?
Tomcat may be freezing when it's doing full GC. I've been watching this by turning on -verbose:gc option. Sometimes it was taking Tomcat 3 minutes to perform the full GC, during which period Tomcat will be freezing, all requests will be queued and not processed. -Original Message- From: Chong Yu Meng [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 28, 2003 9:43 AM To: Tomcat Users List Subject: Re: Tomcat STILL freezing - time to look at another app server?

A newly hired engineer may run into trouble even if he followed the step by step instructions to the letter. And strange stuff can happen to him/her on shift. But on to your problem : I'm thinking maybe the system is doing garbage collection at the time it freezes ...? Do you hear the hard disk thrashing about for a long time during those freezes ? It's happened to me before. The trouble with garbage collection is that you never know when it will kick in. The only other time I encountered freezing was with my Abit motherboard (this is the dual-Celeron motherboard that had the design flaw of an under-powered capacitor). If you are using this motherboard, your best bet is to throw it away. I've never bought anything from Abit after that. Regards, pascal chong Hunter, Sandra wrote: Well this issue continues.
