deploying war file
I have a .war file that has been generated using the java create a war utility. this war file contains html, xsl, images and the associated jar and class files. this war file has worked fine with tomcat and websphere application studio developer, in short, it works by just dropping the file in tomcat/webapps folder or importing the war file using application developer. can a war file generated this way be used with websphere application server by just dropping it into an equivalent webapps folder(if one exists) OR can i use some import war utility. have any of you had any experience with this scenario. please let me know.

Distribution of production systems??
I have an application that is ready to ship and uses basically servlets and JSPs. Our preferred system of choice is Tomcat/Apache, but there might be scenarios where customers would like to choose Websphere or BEA or . In this case we are considering packaging the application as a .war file and sending this accross. I tried the .war file generated with BEA yesterday and it did not work , but the same war file worked with Websphere Studio. So my question is what are the distribution methods that developers out there use to distribute their web applications. 2nd question is what are EAR files and how do they differ from WAR files.

Re: Distribution of production systems??
Hello, Thanks for the reply. Thanks for the short explanation, I am assuming here that war is the way to go for me ;) (pardon the pun) So, that gets me to my second question, should a war created through ant or java's war utility be able to work on any application server (certified or not). because the .war i created worked on Tomcat and websphere out of the box, but did not work on weblogic. shouldnt a .war work on any application server? Please let me know your experiences. Thanks, Brown. - From: Shapira, Yoav [EMAIL PROTECTED] Hi, JARs and WARs and EARs, oh my ;) A WebApplicationArchive (WAR) contains the files for a web application, e.g. servlets, JSPs, static files (html, images, libraries, etc.) and so on, as well as that web application's deployment descriptor (web.xml). An EAR typically contains more than a WAR in that it contains EJBs and their libraries, information, descriptors, etc. It may also contain other, server-specific deployment details. It is common for an EAR file to contain one or more WAR files. An EAR file will have the application descriptor, application.xml. Personally, I use Ant's WAR and EAR tasks to create those files. I'm sure other people have their favorites, as some IDEs have built-in support for this.

Tomcat 4.0.1 on omvs under os390
I am in the process of porting our servlet based application running under Linux to omvs under Os390. After extensive searches on the web, I have not been able to find any kind of documentation/pages that suggest that this configuaration is possible. I believe that it can be done since I can run my Java programs quite nicely under omvs when they are converted to ebcdic. also, the configuration and xml files are text files, so they should not be much of a problem. IBM provides Websphere that does the ascii-ebcdic conversions on the fly and back under os390. My question is that has anyone been able to deploy Tomcat on os390. If they have, how did they resolve the problems of ascii-ebcdic conversions. I would appreciate any kind of information on the subject. Please let me know. Thanks in advance.

Re: Tomcat - OMVS/S390 - Urgent
Has anyone got Tomcat (any version) running under OMVS on S390. If you have a Linux VM on your S390 it will be easy since we package Tomcat 3.3/4.0.2 as RPM ;) BTW, Tomcat is a java apps which could be used on any system with a JDK 1.1.x (TC 3.3) or JDK 1.2 (TC 4.0.2). I used them on our IBM iSeries in OS/400 mode without any problems for months. Henri, Have you had success in making Apache and Tomcat work together under OMVS. So, did you have success in compiling the mod_jk module under OMVS. Can you mention the versions of Tomcat, Apache and the mod_jk that you used during the process, it will be a lot of help. Thanks.

Re: Tomcat Performance Expectations?
Hi Randy, Thank you for your reply. One common misconception that people seem to have about Tomcat (and application servers in general) is that you can predict how well an application will perform on that server without any real details of the application, but exact hardware details. I understand that it is a vague and open ended question and I mentioned it so in the email. What I am looking for is a ballpark figure that might not work for me but will give me something to shoot for/surpass. Not having worked on Tomcat or any other app server performance issues leaves me asking this question. For almost all applications that Tomcat is going to serve, the majority of CPU time will be spent in your application. The majority of network traffic will be specific to your application. The majority of memory might be your application (Tomcat might actually tie with you here). The point being, of all the possible factors that can limit the transactions per second or whatever other performance metric you want to consider, your application is the biggest blocker, not Tomcat, not the OS. That is true. My application does require network traffic. But I have used network monitoring tools like ntop etc. and am sure that network is not a bottleneck for this application. About the memory, I have used OptimizeIt and know where the memory bottlenecks are and am confident that garbage collection takes care of it (though there are some places that can be tuned) My best advice is for you to try it out. Set up a load test and see. One potential bottleneck you didn't mention, by the way, is your bandwidth between you and your users - this can also limit the number of transactions (which is a rather vague term when discussing app servers) you will receive. I have used load tests and for a single test it takes close to 3 min and have tested for 500 instances of the same test at the same time achieving decent performance. Bandwidth is not bottleneck bcoz all users are on T1 line. So what I am looking for are ballpark figures. Hope this information helps you and other tomcat list users to estimate the application. For the benefit of other listers I am pasting the email I wrote earlier below. * I have a single servlet based application. This application is accessed througha browser and travels over to a high performance database through a RMI-IIOP connection. It is not the best application in terms of code tuning. We are deploying this application on Tomcat 4.0.1, Apache 1.3, Suse Linux 7.0 on a PIII 800Mz machine with 800Mz RAM. We are not planning on adding multiple instances of Tomcat/Apache for the time being (or we are not quite sure that our machine might be able to sustain that many threads of either) Based on this what is the maximum number or requests that I can expect to obtain from my applications. Can I expect say 1000 (or maybe 5000 or more) concurrent users. How many requests/sec can I expect while delivering acceptible response on the browser. The reason I have asked such an open-ended question is that you might have deployed your production system on such a configuration and must have achieved some bechmarks.

Re: page not found error using apache/tomcat
When i type in the browser http://x.x.com/examples I get the listings of servlets, jsp and images but when i goto servlets link i get a page not found error and the apache log says File does not exist: I believe this is a bug in the webapp module and I struggled several days about this problem too. You must enter the ending '/' for a directory. e.g. http://x.x.com/examples/ The apache server will use the index.html when it is a directory (e.g.http://myhost/dir) and tomcat will use the index.html too (e.g. http://myhost:8080/examples). However the apache-tomcat interface will not automatically add the ending '/' for you and will not use the index.html or show the files in the directory either. ** when i type http://x.x.com/examples/ i am on win 2k and i see the apache process running at 99% and the browser seems like it is in an endless loop. when u say that u were struggling with this for a while what did u do to resolve it, did u use mod_jk or just the warp connector.

Apache - Tomcat - integration
Hi, I have been trying to make Apache 1.3 and Tomcat 4.0 work together but I was not sure what the different pieces are that I need to make them work together. I have listed a couple of doubts below, please take the time to answer them. 1. What is mod_webwap. Do I need this in my case. I have downloaded and copied the .dll into winnt/system32 and into %APACHE_HOME%/modules and the .so in to %APACHE_HOME%/modules 2. What is AJP connector and what is the relation with mod_jk. Do I need this in my case, according to the docs the AJP connector is required to connect to web servers, but the docs dont say exactly what is to be done (or maybe I have not been able to understand) One of the places that I saw http://www.galatea.com/flashguides/apache-tomcat-4-win32.xml and http://dcb.sun.com/practices/howtos/tomcat_apache.jsp gave an easy guide that does not seem to work in my case. When I type http://localhost/examples the Apache.exe process runs at 99% and never comes back. Please let me know. Thanks in advance.

Tomcat Performance
I have a system that is currently running on Websphere and we are only using the servlet container aspect of it. We have heard good things about Tomcat and were considering to move to it. Have members used Tomcat on production systems and have they achieved success in doing so, in terms of performance and load handling. We are assuming that our system can have upto 100 users login and the same time and could have upto 1000 logged on at the same time. Should this be any problem for Tomcat. Also, has anyone been able to configure Tomcat for load balancing in terms of multiple instances of it running from the same or different machines. Thanks.
