Re: Tomcat setup / config (System.exit if exception thrown)
Le mercredi 07 février 2007 à 23:17 -0800, Lisa a écrit : When starting up Tomcat, I would like to do a System.exit() if an exception of any kind is thrown. Is there a way to configure this? We are using a large number of frameworks (Spring, Hibernate, log4j) and I want the developers to pay attention right away if there is something wrong and to get it fixed rather than ignoring them (or missing them). System.exit() is a bit radical... Why don't you send a mail to everyone when an exception is thrown with the exception? I want to shut things down hard and fast if something is wrong during development and force everyone to throw their hands up and be stuck (and make noise) until it is fixed. Any ideas would be appreciated. L
Help localizing IIS crach running isapi_redirect.dll
We are suddenly experience major problems on all of our four productionservers. We are running four IIS 6 servers on Win 2003 Server which are connected with isapi_redirect (ajp13) to four tomcat 5.5.12 which is mapped 1 to 1. They have been runnning fine in at least some month and suddenly the IIS application pools is crashing for us and we have no idea why, tomcat is running fine and we cant se any problems.

I've verified the absense of jsession id in the URLs accessed by Googlebot in the server logs. This inconsistent appearance of jsessionid for certain set-ups doesn't bother me, it's just a matter of curiosity. hi rashmi, i'm not sure what you're saying; are you asking a question? -Rashmi - Original Message From: Pid [EMAIL PROTECTED] Some bots also use sessions. I disagree, the bot has no capability to decide to use a session. A bot would only appear to use a session if it was HTTP/1.1 capable, and was handling cookies or encoded URLs properly.

IllegalStateException in Tomcat 5.5.X
Hi All. I'm getting some intermittent exceptions from Tomcat with which I would appreciate some assistance. I get an IllegalStateException from Tomcat. This is not a unique error, though it looks like the circumstances causing it are. We have a complex application, with multiple servlets and many JSPs. The specific type of IllegalStateException is a TODO, and it usually occurs when we call sendError() on the HttpServletResponse object. I know this sounds like the typical coding error, but we have checked very carefully and haven't found it. We have looked through many of the posts on other occurrences of this exception, including the Tomcat documentation that describes its common causes. We've checked those method calls (e.g., getWriter() or getOutputStream() followed by a sendError() or similar call), and can't see any logical errors in the flow of code. The exception only occurs when one specific servlet is active. This servlet is a custom proxy, and behaves as an Http client to other servers. Interestingly, the exception doesn't get thrown from the proxy servlet, it actually pops up in several of the other servlets. We put in lots of debug statements and found that sometimes (approximately 20% of the time) the 'isCommitted()' method on the HttpServletResponse object indicates that the response is already committed *upon entry* to the proxy servlet! But even when isCommitted() indicates true, it only occasionally leads to the exception occurring in the other servlets. It seems that Tomcat is getting confused at the core by the proxy servlet - why else would the response appear to already be committed upon entry to our servlet. Possibly this is due to the web client nature of the proxy servlet? Or maybe a subtle bug somewhere in the proxy code that overwrites something internally in Tomcat? We can avoid the IllegalStateException by not calling sendError if the response is committed, but either way the application doesn't behave properly. Environment: We get the same problem on in different environments, which strongly indicates it is specific to the Tomcat 5.5.X line: OS: Windows 2000, Windows XP, AIX JVM: 1.4.2_12-b03 on Win32, J2RE 1.4.2 IBM AIX build ca142-20060824 (SR6) Tomcat: 5.5.7 and 5.5.20 The Tomcat FAQ lists *the most common* reasons for getting an IllegalStateException.

Re: IllegalStateException in Tomcat 5.5.X
This smells of a static-like object which has a race condition in handling of requests and responses. For example - if sessions are used and there is a filter which puts the current request into the session - that will be a problem. Another example: A filter which does user logging/tracking and tracks current requests per user - but doesn't handle concurrent requests from the same user in a reliable manner. -Tim Tom Davis wrote: Hi All.

Re: IllegalStateException in Tomcat 5.5.X
I'm not sure that this is a session-specific issue. We do use sessions, but do not use filters. The data we put in the session object is not (explicitly) affected by the proxy servlet. However, the issues of threading/concurrency and static object access are good ideas to investigate next. Up until now we had been focused primarily on the 'straightforward' issue of whether or not we had a logic error in the committing of a response. The threading issue makes a lot of sense, as the problem is intermittent. We'll dig a bit there. Thanks, Tom Tim- Jumping into the middle of a thread is always dangerous but that said..

CGI environment variables
Hi, I have an issue with CGI scripts (Perl based) running under Tomcat on Windows 2000 getting URL's wrong by using backslashes instead of forward slashes. Notes: 1. I've setup CGI support as detailed in the how-to for Tomcat 5.5 2. I either have to set passShellEnvironment to true or set the systemroot env var at the top of any Perl scripts in order to be able to open a TCP/IPsocket. Otherwise I get a Can't create TCP/IP socket (10106) error. 3. As such, I have passShellEnvironment to true. 4. If I list the environment variables in Perl - for SCRIPT_NAME I get a leading forward slash whilst the remaining are backslashes. for example: SCRIPT_NAME = /cgi\path\to\script.cgi 5. Running Perl scripts on the server inserts backslashes for url's after /cgi which results in many problems. Maybe I'm missing something obvious but I've looked everywhere for some info on this and come up empty handed. Does anyone know how to fix this?
