RE: Help with running Tomcat
Another simple solution is to redirect stdout and stderr to text file like this: startup.bat 1std1 2std2 where std1 and std2 are quasi-arbitrarily chosen file names. This approach is convenient when you do not want to modify the contents of startup.bat. However, you will need to either open another shell or navigate to those files in Explorer Regards, Oswald Ariel Valentin [EMAIL PROTECTED] wrote: Edit the startup.bat file and enter the word pause at the end. This will stop the window from closing and you can see what the error is. Also have you tried looking at the server logs? I am not sure if it writes anything but it is worth looking at. Mr. Ariel S.

RE: How to deploy a web application under Tomcat 5
Hello, Elisabeth: You can do something like this: cd parent-of-WEB-INF-directory jar cvf myFirstManualWarFile.war .

I only need Tomcat to recognize the structure MyApp | --- WEB-INF | classes lib web.xml Tomcat will recognize this structure: create a directory called MyApp in your webapps directory, and create the above directories/files under it. Restart tomcat, and you'll be able to access http://localhost:8080/MyApp. There won't be anything there, of course. Create a simple test.html page and try http://localhost:8080/MyApp/test.html.

Re: Hanging tomcat processes on heavy access
Hello, Chris: I have a couple of suggestions (but no answers). 1) you can attach to a process with the 'truss' command and monitor the read/write activity of the process. Syntax, options, and examples of truss can be had via man truss or Google Unix truss command. This *might* reveal something. 2) you can kill hanging processes and release the port via a Unix command (the name escapes me right now), which may help reduce the number of time you need to reboot 3) try experimenting with the min/max heap size for Java; perhaps you can set both of them to small values in a test environment to quickly reproduce the problem and use #1 Since other people can continue working normally, it does not appear that you've read the maximum number of socket connections (338, if I remember correctly). Did this problem start after having installed new software or changing the environment? Perhaps you can try rolling back to see if the problem disappears Cordially, Oswald Christoph Fischer [EMAIL PROTECTED] wrote: Hello everyone, here is my configuration: linux server with tomcat 4.1.29 connected to apache 1.3.29 via nod_jk java version 1.4.2_03 from tomcat server.xml port=8009 minProcessors=5 maxProcessors=500 acceptCount=10 debug=0/ At heavy access times the user gets a blank screen on the browser and on the server a java process is hanging. Tomcat is still working and responding to further tasks, but the 'hanging' processes will stay around until reboot. Unfortunately the hanging processes will also keep a socket connection on port 8009 to apache, so after some time the system hangs due to too much connections. I could rebuild this situation also with jmeter and a simple servlet which only responds a simple html site, so the problem couldn't come from my coding. How can I solve this problem ?

RE: Apache/Tomcat/Struts Certification Proposal
Hello, Drew: Perception is reality but reality isn't necessarily perception has proven itselt many, many times. People often need credentials in order to _get_ the job but not to actually perform the tasks, especially with the current supply/demand imbalance. Non-technical hiring managers can't possibly determine who has the best technical skills, so they try to decide if the person sitting on the other side of the table 1) can do the job, 2) will do the job, and 3) will also get along with others (to state the obvious). I've read e-mail in one certification-related group on yahoo about freely available downloads of entire certification tests, and comments from the sender about having friends who know nothing about technology xyz and yet were able to pass the exams; this also puts the non-technical hiring managers in a precarious position. There is clearly no substitute for experience, yet I've seen people with 20 years experience in a field where they've been doing the same thing for the last 17/18 years. Credentials (IMHO) tend to demonstrate that you have follow-through, similar to completing college, though dropping out does not constitute failure or lack of intelligence (think of Bill Gates:)). I know someone who got a job (several years ago, mind you) at HP because she had won a high-school level prize for her knowledge of Japanese, which distinguished her from the other job candidates. That knowledge had absolutely nothing to do with the programming job, yet it was a perception-based factor that weighed in her favor. Ah well, such is life Oswald Hamilton Andrew [EMAIL PROTECTED] wrote: I tend to agree with the certifications are BS argument. I have several certifications and they don't really help me do my job. Unfortunately, in the climate we are in these days, the fact that there are certifications lead us down the road to being forced into acquiring them. When faced with the likelihood that the hiring authority in a company may not be an engineer, but a human resource manager and the requirements for the position are certification in this, that or the other technology, even though I may have 5 more years worth of experience, my resume my get tossed aside because I don't have the piece of paper that tells them that someone else thinks I know what I'm doing, which may sound ridiculous but is still true. It is disheartening to see because I switch jobs every three years and more and more I see that someone wants you to be an SCJP, SCJD, CCIE, CCNA, MCSE, MCSD, or what have you (does this remind anyone of alphabet soup). I think there are ways for you to showcase your skills in your resume without having to resort to getting certifications but it just seems to me that sooner or later there is going to be some form of certification REQUIRED for a lot of positions.

RE: Tomcat OutOfMemory at 158MB - Not reclaiming any memory overn ight
On Unix you can also use the truss command to attach to a running process (check Google for examples). I used this technique on a web application and discovered that a file with *static* content was being opened 1,000 times per hour by the application. Before I showed up at the company, everybody was working on NT and basically hated Unix, so the problem went undiscovered for close to four years. AFAIK, most (all?) of the Java-based tools would not detect this sort of problem. I don't think truss is available on NT, even with the MKS (or equivalent) package. For people who are on NT and are experiencing problems with their Java-based web- application, I would strongly recommend setting up a Unix environment to perform truss-based testing (even if you need to hire a contractor to set up everything). It's really quite amazing what truss can uncover:) Cordially, Oswald Edson Alves Pereira [EMAIL PROTECTED] wrote: JProfiler is the best for this job, there are examples to show you how bind JProfiler to tomcat ( www.jprofiler.com ), its pretty easy to handle this tool. -- De: Allistair Crossley[SMTP:[EMAIL PROTECTED] Responder: Tomcat Users List Enviada: quinta-feira, 8 de janeiro de 2004 8:58 Para: Tomcat Users List Assunto: RE: Tomcat OutOfMemory at 158MB - Not reclaiming any memory overnight Yes I would like to profile my applicationbut do you have any tips on how to do this or where to start?

This is our development version of Tomcat. Looking at the Windows processes revealed Tomcat at 158MB. Let me do some divination. You are using a SUN Jvm, with no Xms nor Xmx parameter. So, the memory allocated to your applications is 64MB (default). 158 is a good value reflecting the size of the VM plus the size allocated to your applications. If your application needs more memory, try to path -Xmx=128m -Xms=128m to your startup scripts. Hope this helps, François (Oraculum). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --- QAS Ltd.
