RE: will pay money for tomcat install
Hey, Don't spend money and use my Redhat RPM to install tomcat on a Redhat Linux Box (i386). 1) Go to : http://rpmized.free.fr/rpms/tomcat/ 2) Download all stuff = tomcat-3.2-beta7.1.src.rpm (tomcat RPM source) tomcat-3.2-beta7.1.noarch.rpm (tomcat RPM with java stuff) tomcat-manual-3.2-beta7.1.noarch.rpm(tomcat manual (fall in /home/httpd/html/manual/tomcat) tomcat-mod-3.2-beta7.1.src.rpm (tomcat/apache connectors RPM source) tomcat-mod-3.2-beta7.1.i386.rpm (tomcat/apache connectors RPM i386) 3) rpm -Uvh tomcat-3.2-beta7.1.noarch.rpm (at this moment you can do : http://yoursystem:8080/examples/ 4) rpm -Uvh tomcat-mod-3.2-beta7.1.i386.rpm (if you want to use tomcat with apache - http://yoursystem/examples/ ) 5) Go to amazon.com and buy me the latest O'Reilly book on Servlet (2nd Edition) ;-)

RE: workers - loadbalancing
first off, thanks for all the replies and sorry for responding 2 days too late :-) Alistair Hopkins: A guess, but do green threads show up in your monitoring? if sun uses green by default, but blackdown uses native, you may not see the green as they are internal. Al. Indeed you are right. the SUN jdk uses the green threads! i just wonder if there is any difference in speed, whether green or native threads are used ? unfortunately my _very_ limited knowledge of java, respectively my knowledge of how the JDK works ends here :-) (btw, this is kind of off-topic, but is there any site that compares the speed of the different JVMs from the various developers ?) David Oxley wrote: I believe the worker.ajp13.lbfactor parameter is only the priority of this worker (not the number of processes). You must start your own processes seperatley as in virtual hosting and set up your worker.loadbalancer.balanced_workers to point at the various workers you have set up. You must then swap your config in mod_jk.conf from using ajp13 or ajp12 to use lb. i do have a setup like this (currently experimenting with multiple tomcats), but how does one calculate the right settings for the lbfactor? or are, for example, these settings sufficient: ServerA (slow): 1 ServerB (fast): 2 ServerC (light-speed): 3 One more question i wanted to ask: if i have a setup with like 100 virtual hosts on one machine, and tomcat on the same server, is it a good idea to set up more than one tomcat for these hosts ? i thought about the following: 100 hosts - 4 tomcats - each tomcat responsible for 25 virtual hosts or another scenario: 100 hosts - 2 tomcats - each tomcat responsible for 50 hosts my thoughts behind all this are, that, if one tomcat dies by whatever reason, there would still be another one left to serve the remaining host, in order to guarantee at least some functionality in an environment without any loadbalancing software / hardware. regards, christopher blasnik mailto:[EMAIL PROTECTED]

Same error message (as above). Now you write I should include jasper.jar in my classpath. Hmm. Surely an important piece, that jasper.jar but locate jasper.jar doesn't give me any hit. Strange.

Re: Apache is writing 800\n to servlet response outputstream.
Sounds like apache is chunking the output stream, which seems a reasonable thing to do. Do the headers mention anything about chunking? What happens if you have a static image served by apache, out of interest? Jon

JServ vs. Tomcat
Hi, I work for an free web based mail service, Another.com. We are interested in migrating our service to use either JServ or Tomcat. We currently has a server farm with 10 web servers running Apache and a JRun on each machine. We are interested in changing the architecture to use a small number of Apache web servers (e.g. 2) with a set of load balanced Tomcat or JServ boxes. My understanding is that this arhitecture could be achieved with either Tomcat or JServ. Tomcat is perferable from a developers perspective, but is Tomcat considered subitble for a production environment? I was particulatly worried by the problem of Apache hanging when Tomcat is restarted. Since we release new build of the site regularly, we need a mechanism to rollout new builds onto servers. Concider the following example: We have 2 appache servers (WEB1, WEB2) connecting to 6 Tomcat server (TC1 - TC2). Initial all the tomcat servers TC1 - TC3 are running build 1.0. TC4 - TC6 are out of use. We want to release build 1.1 onto TC4 - TC6. We then need to configure the web boxes to send all new sessions to TC4 - TC6, whilst maintaining old session on TC1 - TC3. Can this be done without restarting the WEB1 and WEB2. At some later date we need to restart TC1 - TC3 with build 1.2, whilst maintain sessions on TC4 - TC6. If we restart TC1 - TC3, will this cause WEB1 and WEB2 to lock? I would appreciate any advice or comments. Cheers Tim Wright Java Engineer Another.com

Re: I have tried to invoke EJB's from TOMCAT: NoInitialContextException:
Peter, It looks like your JNDI context info isn't initialized (stating the obvious - I apologize). I had a similar problem (with env-entry constructs). Tomcat 3.2 doesn't come with any JNDI so I had to add a JNDI service layer of my own. Prior to the servlet that makes the EJB call, the JNDI environment needs to be initialized such that any JNDI lookup calls know where to start looking from. Given I'm not an EJB wiz by any stretch of the imagination, all I can say is check the EJB documentation from ORACLE that specifies the setup steps needed to ensure that the intial context will succeed - I suspect that the EJB call is trying to find EJB home or something or other from the JNDI service. To solve my problem, I wrote a (very) simple interceptor that set up the initial context information for the JNDI that I'm using in the preService call of the interceptor. Sorry if I can't be of much more help. I hope that you solve your problem. Tomcat 4.0 looks to be much, much nicer in the JNDI area and for support of the ejb-ref construct (which Tomcat 3.x doesn't deal with). -Thom Peter Knight wrote: I have tried to invoke EJB's from TOMCAT and get: Internal Servlet Error: javax.servlet.ServletException: Need to specify class name in environment or system property: Root cause: javax.naming.NoInitialContextException: Need to specify class name in environment or system property: e.t.c.

Re: EJB
Actually, Peter is not using JOnAS, he is using Oracle. Somewhere in the Oracle
documentation, it should say what type of environment you need to pass into the
new InitialContext() call or have in your jndi.properties file.
Typically, the parameters you will need are:
java.naming.factory.initial=some oracle class that extends
javax.naming.spi.InitialContextFactory
java.naming.provider.url=some url specific to Oracle
java.naming.security.principal=user_id
java.naming.security.credentials=password
These can be in a properties file called jndi.properties in your classpath, or you
can programatically set them into a Hashtable and pass the hashtable into your
InitialContext constructor.
Simon,
What I did to get the parameters was to put them in my web.xml file like:
context-param
param-namejava.naming.factory.initial/param-name
param-valuecom.inetbasics.server.naming.provider.rmi.RMIContextFactory/param-value
descriptionblah/description
/context-param
context-param
param-namejava.naming.provider.url/param-name
param-valuermi://localhost:900/Storesmith/param-value
descriptionblah/description
/context-param
I then read them and pass them to InitialContext:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
servletContext.getInitParameter(Context.INITIAL_CONTEXT_FACTORY));
env.put(Context.PROVIDER_URL,
servletContext.getInitParameter(Context.PROVIDER_URL));
if (userName != null)
{
env.put(Context.SECURITY_PRINCIPAL, userName);
if (password == null)
password = "";
env.put(Context.SECURITY_CREDENTIALS, password);
}
Context ctx = new InitialContext(env);
That works well for me, because I have to set the user id and password, but you
might not like the complicated way of setting the InitialContext. I am
considering writing a security interceptor to do this stuff for me, however.

Re: Tomcat 3.2 beta and PHP
Hello Christian, I'am happy to see someone else in the world has tried to use PHP and Tomcat together. Sooo!! Which version of PHP work (or doesn't work) on Windows? For the moment, I only really try on SUSE 7.0. with Apache. Which results did you get? Personally, I get the following: - exchange of simple data like boolean, string, int, double and array of string (String [][] for example). - I wrote a class who is running in Tomcat to make some request from PHP and give the result to PHP. Problem: it crashes sometimes. I compiled PHP whit jdk1.3 from SUN and run Tomcat whith the samke jdk, adn know it seems to be stable. But! - with phplib, I can use common session variable with PHP and Tomcat. The adavantage: you can reach the session variable from PHP and from others Java classes/applications. The problems I found: - Generally, php as servlet doesn't seems to be really stable (Tomcat crashes, not really often, but I am not hapy with it). - Sometimes mit Tomcat hang up (it doesn't answer to www request). - if I make an include in a PHP file and use the same include later, I become some strange result : page not completly downloaded.

RE: Why tomcat NT service get killed when the user log off
Title: Why tomcat NT service get killed when the user log off Zhiping, even though jk_nt_service is being used to launch Tomcat, there is a bug in the Java 1.3 runtime under Windows that causes any java.exe process to be terminated when the user logs off. The bug is that a console control handler is setup inside of the java runtime that detects the CTRL_LOGOFF_EVENT that is sent by Windows to each process when the user logs off and the handler inside of Java 1.3 is terminating the process when this occurs. This is the correct operation for a normal application running but not the correct one for a service. There is a couple of packages around, one being located at http://www.kcmultimedia.com/javaserv another at http://www.eworksmart.com/jnt that handle the CTRL_LOGOFF_EVENT. I tried a couple of these and while I found that they indeed to stop the application from being terminated by the CTRL_LOGOFF_EVENT, I found that they interferred with the normal shutdown of Tomcat. That is, using these packages, I was not able to shutdown Tomcat cleanly, which caused the servlets to not have their "destroy" method invoked. The reason that this occurs is because the way that these packages work is that they invoke the Java VM using the JNI interface. When Tomcat is to be shutdown, the same JNI interface is used to invoke a shutdown method. The problem occurs because the way that Tomcat (3.x) is shutdown is by using the APJ interface to send the existing Tomcat instance a APJ shutdown message (through a TCP connection in fact). These packages send the APJ message using the JNI interface, but when call returns, they assume that Tomcat is ready to be shutdown and they then tear down the Java VM running the Tomcat process. In reality, the Tomcat process has not yet received the APJ message through its socket interface and as such has not shutdown cleanly and does not give the servlets a chance to have their "destroy" method called. Because my application needs to have the servlet's "destroy" method called when Tomcat shuts down, I solved this problem by using the source to "java.exe" launcher as a starting point and then modified it to install a console control handler that ignores the CTRL_LOGOFF_EVENT. I called this new launcher "javaex.exe". I then used jk_nt_service and changed the configuration file references of "java.exe" to "javaex.exe". I hope this helps. -Original Message-From: Zhiping Wei [mailto:[EMAIL PROTECTED]]Sent: Wednesday, November 15, 2000 5:38 PMTo: '[EMAIL PROTECTED]'Subject: Why tomcat NT service get killed when the user log off Please Help!!!

Jsps on subdirectorios of web/
Hello all, I'm using tomcat on a project and I have run into the following problem: A coworker built a webapp, all his classes are in web-inf/classes, and all his html/jsps are in the webapp root. I'm now writing an additional module for the webapp, but I must put my classes and jsps on different directories than his. So for the classes I just put my source files on a package, and I made a subdirectory on web to put my jsps. The problem I have is that I cannot use his classes from mine or from my jsps. I guess I must import or qualify his classes with a package name, but for the life of me I can't figure it out. I've looked at the jakarta-tomcat faq but have been unable to find a solution for this. Any help would be greatly appreciated. -- Victor R.

Re: /test interferes - how to get rid of it?
When you unpack the distribution of Tomcat it comes with several WAR files (inlcuding test.war admin.war and examples.war). You have to: - get rid of the WAR files - remove the corresponding directories - and of course, remove the contexts from xerver.xml (I had the same problem, but with an /admin directory) Julio - Original Message - From: Christoph Kukulies [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, November 15, 2000 11:29 AM Subject: /test interferes - how to get rid of it?

The Enumeration doesn't give an error but it doesn't fill up, despite
the fact that there is definately a session open (you need to be

Dave Molloy
See the Servlet 2.2 specification at
http://java.sun.com/products/servlet/download.html, and the
corresponding servlet API Javadocs. You will find that the
getSessionContext() method has been deprecated, and returns an "empty"
session context. Likewise, the ServletContext.getServlet() method has
been deprecated, and always returns null. These tend to be the two
largest issues when porting applications based on the servlet 2.0 API (as
Apache JServ is).

Re: downloading Word doc
Laurens Pit wrote: Can someone get this to the developers? Thanks. The most likely scenario is that JRun has a predefined MIME mapping that tells it to download Word documents as "application/ms-word", and Tomcat doesn't. To change this, add an appropriate mime-mapping entry in $TOMCAT_HOME/conf/web.xml (for Tomcat 3.1). For 3.2, there is unfortunately no easy way to adjust the default MIME mappings. Craig McClanahan
Re: Please Look - 3.2 beta 7 problem - RequestDispatcher include()
Wyn Easton wrote: Are you not suppose to mix URL access with a RequestDispatcher? Thanks. Also, in 3.2 beta 6 I could do an include() then a forward(). Now in 3.2 beta 7 I get an illegalState error on the forward() because of an open outputstream. I'm not opening an output stream. The include() must be doing it. This assumption is pretty close to being correct. There was an absolutely horrible bug in 3.2 that caused all sorts of problems with included servlets and JSP pages. The "quick and dirty" workaround was to have Tomcat 3.2b7 commit the response before processing an include -- which is what causes the forward to fail now (since you cannot do a forward after the response is committed). Fixing this the right way this would require some fundamental changes to 3.2's architecture, which are unlikely given how late 3.2 already is. As a workaround, I would suggest that you change your application logic to decide if you're going to do a forward *before* you actually do the include. (The include is wasted anyway, since any output it produces would be thrown away.) Craig McClanahan

In short you should make a directory for your application. Say c:\test\cusinf where cusinf is the application. cd test\cusinf mkdir src mkdir etc mkdir lib mkdir web copy/build web.xml into etc ( See sample directory listed in documentation) copy/build build.xml and build.bat files for compilations in c:\test\cusinf area copy your servlet java files into src run build.bat file in the c:\test\cusinf It should build the applications move your directory tree into webapps.
