CGI servlet in tomcat
In the web.xml, I've uncommented the servlets ssi and cgi. I've also -uncommented the servlets-mapping for these 2 servlets. I've renamed the servlets-cgi.renametojar and servlets-ssi.renametojar files. Where do I place the folder cgi-bin? Are there any other changes to be made to use the CGI servlet? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Vedr.: IIS + Tomcat 5.0 + NT authentication AUTH_USER
Simply put request.tomcatAuthentication=false somewhere in your jk2.properties file. /Thomas Jason Wilson [EMAIL PROTECTED] 08-01-04 18:54 Besvar venligst til Tomcat Users List Til:[EMAIL PROTECTED] cc: Vedr.: IIS + Tomcat 5.0 + NT authentication AUTH_USER Hi, I'm using Tomcat 5.0.16 connector-jk-2.0.2-win32-iis IIS 5.0 Currently my application is running under IIS + ColdFusion(Jrun), but will be migrating to a IIS/Tomcat server. Since this is an intranet application on an NT network, where it is a requirement to have the users not have to implicitly logon, I am using NT authentication with IIS. In other words, for the virtual directory, I have set the Anonomous access off, and Integrated Windows Authenticated on. In the IIS + ColdFusion setup, my servlet does a request.getHeader(AUTH_USER); and this returns the domain/userid of the person logged into the client machine. Then I can verify the user is allowed to use the application. All is well. However, in the IIS + Tomcat setup, getHeader(AUTH_USER) is returning null. I have tried other header keys and get null also. Also, I am sure IIS is authenticating the user, since I cannot get to the application using a browser that doesn't support the windows authentication. So, it appears, for some reason, the connector is not setting the AUTH_USER header when it transfers to the Tomcat container. Does anyone know how I can fix this so it does, or if there is anything I might be doing wrong. Thanks in advance, Jason __ Do you Yahoo!? Yahoo!

Re: Tomcat don't receive the right URL from mod_jk2 (or mod_jk) with IIS 6.0 on Win 2003 Server?
Hi Daniel,
filename of the jk2 redirector is isapi_redirector2.dll, so
isapi_redirector.dll will never be found,
I've renamed the dll, so it is really found.
example directorys of Tomcat5
I'm using Tomcat 4 (I can reach http://localhost:8080/examples/ with no
error).
we build an installer which automates all steps at:
http://www.shiftomat.com/opensource/
Whatever I've tried your installer, nice one but it still not working
with an error that looks like the one I have with my previous installation.
(Before try the installation I've removed my jakarta virtual directory
to let the installer do its job)
I mean I reach the page 'The page cannot be displayed...
You can find logs and config below.
I'm totally lost. Especially I don't understand why
--- HttpFilterProc check if [/jakarta/isapi_redirector2.dll] is
pointing to the web-inf directory
although before the mapping was matching
HttpFilterProc [/examples/] is a servlet url - should
redirect to lb:lb

Problems after creating new hosts / contexts
Hi all,
my environmemt:
OS: Redhat Linux
Platform: Intel x86
TC version: 4.1
tomcat4.conf:
--- cut -
CATALINA_HOME=/var/tomcat4
JASPER_HOME=/var/tomcat4
CATALINA_TMPDIR=/var/tomcat4/temp
cut -
First: There are a few of hosts and contexts running withouts problems
.. but when I'm setting up contexts in new hosts, I've problems whith
this new ones:
1. I create a hosts AppBase directory like
$HOME/html/servlet/
for the domain diving.co.at
and a DocBase directory for the context
$HOME/html/servlet/myapp
and context path: /myapp
I put a test.jsp[1] file in DocBase.
2. I configure the new host and context in the TC Admininstration Tool
with the settings from 1.
TC is deploying[2] but http://www.diving.co.at:8080/myapp/test.jsp
always returns the error:
HTTP Status 500 ..
javax.servlet.ServletException: org/apache/jasper/runtime/HttpJspBase
...
but an older host http://pronet.at:8080/tomcat/test.jsp with the same
test-file and the same TC engine works fine!?
When I'm looking in the TC-wrok-dir .. there are also the files:
test_jsp.class test_jsp.java
TC is compiling test.jsp .. but returns the error shown above .. why?
What's going wrong there?

RE: mod_jk2 JNI question for the brave :)
Yep I see what you mean know (fog of stupidity lifts).

How about this then..instead of launching several tomcat instances (which you cant), why not create a virtual tomcat construct?

Are you using the Tomcat as in or out of the process? In process tomcat (invoked from webserver) can be used only with the single worker mpm's. If you have multiple worker processes each of them would need to load it's own Tomcat instance, but try to start the two TC instances from startup.sh. The second will die immediately. Think that under linux there is no mpm that will allow you to have a single child process. Even the threaded, launches a few childs and shares the connection threads among them.

I'm using Tomcat 5.0.16 , do you know if this version has already been fixed? No. I just fixed it, so 5.0.16 doesn't have the fix. Well, after some tests, i think that i found the source of my problem. The method response.setBufferSize(), only allows me to set a buffer higher than 8192 bytes. If i try to set a lower value it just ignores it and keep the default of 8192. I confirmed this with: response.setBufferSize(n); System.out.println(BufferSize=+response.getBufferSize); // if n8192 it aways prints 8192, otherwise print the value of n The buffer allocated is at least as large as what you are requesting. I still would like to know if there's any way (ugly or not, it doesn't matter how) to disable this buffering... So i can detect when the client closes the connection. For now, use socketBuffer=-1 on the connector. That will likely fix the issue.

If I use the www.host.com (http://www.host.com/web1/), it is still the old jar files that are used(??) Why is that - does anyone know? I am using tomcat 5.0.9.

RE: Problems with Tomcat and JNI
Pablo - What do you mean by Tomcat Crash, is there an exception message at all? If you aren't using a web-application where you could see the error message on the displayed page, you can check the Tomcat logs to see what Tomcat is complaining about prior to the crash. I have two different web-applications that use JNI to access a C device driver and a VB DLL for some server software on one of our cabinets. In general, we would get something along the lines of an unsatisfied link error on the line where you first make a call to the native function (not where you do the System.loadLibrary(XXX), that usually succeeds). The problem for me (and a fellow developer attempting something similar) was that when we created the JNI header file javah -jni ... (-jni is now a default, so its unnecessary to specify it) we didn't include the entire path to the package/class of the java file using the jni. Generally with jni (at least in my exp.), you end up with a header file created by jni that has a very long name - as it includes the entire path to the class file that uses the jni functions (such as mil_navy_XXX_XXX_XXX.h) in my case. If you have created this header file incorrectly, you will still be able to run the application statically - but as soon as you run it through tomcat and it attempts to go through the JNI to access the native function, it will fail because it cannot link to the appropriate location for the function.

External Access to Server (Servlets)
I am new to Tomcat and Servlets/JSP but things are going great except when I try to access the server from outside my house. I can access the home page (default Tomcat page), and I can also access various HTML files. But when I click on a link that uses a Servlet, the page will not display. I does however work fine when I am logged in locally and running things. (IE: http://localhost/Books/myBooks.htm ) More specifically I am testing the Book Catalog example in Chapter Nine of Marty Hall's Core Servlets and JavaServer Pages. Everything work perfectly running it locally! Does anyone have any ideas? Thanks so much, Gerry Oakson
Re: ServletContextListener: how to suspend web app on error
A simple generic way is to use a filter which executes on all requests.
If the ServletContextListener has an error - it can set a variable in the
application context.
Then the filter can check for the existence of that variables. Then forward
to an error page.
For example ...
doFilter( ... ) {
if (null!=servletContext.getAttribute(startupError)) {
servletContext.getRequestDispatcher(/WEB-INF/error.jsp)
.forward(request, response);
} else {
chain.doFilter(...);
}
}

Seems like a simple question, can't seem to find the answer...
If an error occurs in the #contextInitialized() method of an object that
implements ServletContextListener, how can I suspend the web application
so that it is unavailable for use by clients?
Specifically, I have a ServletContextListener that needs to be run at
application startup. If any one of many errors occur, I want to notify
the appropriate people (this I can do) and make the entire webapp
unavailable (this I can't figure out).
Any help is appreciated. I have a feeling this is obvious and I'm just
missing something.

Re: CGI servlet in tomcat
You place the scripts in your webapp. For example, you should have a ROOT context in a default install under %CATALINA_HOME/webapps/ROOT. In there create a cgi-bin directory. If you have other webapps - you can create subdirectories int here to. If you wish to forgo /cgi-bin/ you can map *.cgi to cgi by editing web.xml in any webapp or $CATALINA_HOME/conf/server.xml -Tim [EMAIL PROTECTED] wrote: In the web.xml, I've uncommented the servlets ssi and cgi.

How does a servlet request work. Not a newbie question ;)
Hi all I want to insert some form of scheduling into our application and I was wondering how Tomcat passes the request to the actual servlet I write. Does Tomcat just read the headers to create the request object and leave the body of the message in an inputstream for the servlet to read or is all the data in the request read by Tomcat before passing it to servlet? Some of my traffic is more important that other based on headers in the request. I want to prioritise the handling of requests under load conditions. Any input on this is welcome.

RE: odd subclassed-servlet behavior
Yoav, thank you for your reply. The classes are all packaged up neatly into .wars and .jars inside of a .ear. I have no reason to believe they are not all being loaded by the same classloader, but JBoss is a heavy beast, and I could be wrong. I did do a server stop/start to avoid any weird hot-deployment issues. I also made sure JAVA_HOME was set and pointing to my jdk1.4.2 directory. Code-wise, I provided a simplified description originally. The actual code is not ready for any sort of peer-review. Also, I am not satisfied with the architecture as described below, and will be refactoring it. The problem will probably, at that point, disappear. I guess I'm just checking for a known problem of some kind, some specific bug that I should be looking for that displays these kinds of symptoms. Thank you, and thanks to the whole Tomcat team! This is one hell of a piece of work. Bill On Thu, 8 Jan 2004, Shapira, Yoav wrote: Howdy, Can you share the relevant code? Are the classes all being loaded from the same classloader?

I have just upgraded from JBoss/Jetty 3.0.4 to JBoss/Tomcat 3.2.3, and have noticed some rather odd behavior. I have 3 servlets: SuperClazz |--- SubClazz |--- SubSubClazz SuperClazz subclasses HttpServlet but is not meant to be called directly, but SubClazz and SubSubClazz are both standalone servlets and I call them directly depending on what I need. SubClazz does general things, and SubSubClazz does more specific things. SubClazz delegates to SuperClazz and SubSubClazz delegates to SubClazz as needed. This was working in JBoss 3.0.4 and Jetty. However, in Tomcat 4.1.29 just now I observed that calling SubClazz directly resulted in SubSubClazz getting the call, then execution tracing straight to SuperClazz, _then_ SubClazz. SubSubClazz was the last thing executing before it failed. (That failure is the thing; SubSubClazz doesn't have what it takes to handle my request, and I don't want it called.) Here is an example of my problem. By calling the URL: http://localhost/myApp/servlet/SubClazz?a=1 I get this output from the running server: 10:23:24,020 INFO [STDOUT] [SubSubClazz.doGet] GOT HERE 1 10:23:24,020 INFO [STDOUT] [SubSubClazz.doPost] GOT HERE 1 10:23:24,020 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 1 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 2 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 3 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 4 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 5 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 6 10:23:24,021 INFO [STDOUT] [SubClazz.doPost] GOT HERE 1 10:23:24,021 INFO [STDOUT] [SubClazz.doPost] GOT HERE 2 10:23:24,021 INFO [STDOUT] [SuperClazz.doAThing] GOT HERE 1 10:23:24,023 ERROR [Engine] StandardWrapperValve[SubSubClazz]: Servlet.service() for servlet SubSubClazz threw exception java.lang.IllegalStateException: Cannot forward after response has been committed at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDis patc her.java:368) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispa tche r.java:356) ...bad stuff happening since correct calling order is not happening... Can anybody explain why: SubClazz is being skipped and SubSubClazz is getting the request in the first place? SubClazz is not getting the super() call, but instead it is going straight to SuperClazz?

Tomcat 4.1.29: Pool exhausted
Hello, I tried to move my web application from Tomcat 4.1.27 to Tomcat 4.1.29. The application has a JNDI datasource. Everything worked properly in 4.1.27, but after I moved to 4.1.29 I've got an exception: Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot get a connection, pool exhausted, cause: java.util.NoSuchElementException: Could not create a validated object at org.apache.commons.pool.impl.GenericObjectPool.borrowObject(GenericObjectPoo l.java:851) at org.apache.commons.dbcp.PoolingDataSource.getConnection(PoolingDataSource.ja va:140) at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:5 18) at net.sf.hibernate.connection.DatasourceConnectionProvider.getConnection(Datas ourceConnectionProvider.java:59) at net.sf.hibernate.impl.BatcherImpl.openConnection(BatcherImpl.java:257) I know that 4.1.29 has the newest versions of Dbcp and Pool. May be some new parameters appeared for Dbcp 1.1. I think it is the reason of my exception.

RE: How does a servlet request work. Not a newbie question ;)
Hi Nix I need to read the headers to see if the request can be moved up in priority. If no I will put that particular servlet into a wait state to be woken up by some scheduler I create in the servlet engine. Ideally, all requests will be processed but some will be done before others. It is not a login or cookie application. We are not using browsers to access the application so the headers are customizable and we know the type of message arriving. It's just we want some types of messages to be done. Under load we can reject certain messages that are not high priority if an internal processor cannot be assigned with a specified time frame.

Connector className=org.apache.coyote.tomcat4.CoyoteConnector port=8443 minProcessors=1 maxProcessors=1 enableLookups=true acceptCount=2 debug=0 scheme=https secure=true useURIValidationHack=false disableUploadTimeout=true Factory className=org.apache.coyote.tomcat4.CoyoteServerSocketFactory clientAuth=false protocol=TLS / /Connector I start Tomcat with this setup and see that it has only one object in its connection pool as expected. I have a small servlet that just returns a number (incrementing) and has a forced pause to simulate work being done. 2 seconds wait. I send the request with Browser 1 to the servlet and it doesnt return yet. Should be asleep for 2 seconds I send the request with Browser 2 to the servlet and it does noting but looks like its busy as expected as maxProcessors=1 above Browser 1 now returns with its incrementing number Now I expect browser 2 to be assigned to the free connection in Tomcats pool but nothing happens ever. Browser 1 goes again and works after 2 seconds. Q: Why did browser 2 not get assigned the servlet that browser 1 freed up when it finished the request Q: Does the acceptCount does what I think it does? Thanks for any help in understanding how this works. Donie - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tomcat 4.1.29: Pool exhausted
Hello, I tried to move my web application from Tomcat 4.1.27 to Tomcat 4.1.29. The application has a JNDI datasource. Everything worked properly in 4.1.27, but after I moved to 4.1.29 I've got an exception: Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot get a connection, pool exhausted, cause: java.util.NoSuchElementException: Could not create a validated object at org.apache.commons.pool.impl.GenericObjectPool.borrowObject(GenericObjectPoo l.java:851) at org.apache.commons.dbcp.PoolingDataSource.getConnection(PoolingDataSource.ja va:140) at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:5 18) at net.sf.hibernate.connection.DatasourceConnectionProvider.getConnection(Datas ourceConnectionProvider.java:59) at net.sf.hibernate.impl.BatcherImpl.openConnection(BatcherImpl.java:257) I know that 4.1.29 has the newest versions of Dbcp and Pool. May be some new parameters appeared for Dbcp 1.1. I think it is the reason of my exception. When I replace version 1.1 of Dbcp and Pool to version 1.0 in common/lib of Tomcat 4.1.29 - everything started working well! I wonder if anybody got success using JNDI datasource and Tomcat 4.1.29. Tomcat works under J2SE 1.3.1. Thanks. Dmitry - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: How does a servlet request work. Not a newbie question ;)
Howdy, I see three options that fall within the realm of not a huge amount of work: - Dig into tomcat source code, extend Coyote in some custom way to recognize your headers, recognize what you call load (which is much harder to do than recognizing headers), and filter requests appropriately. - Create a simple Filter (ServletFilter) that looks for your request headers, again recognizes load, and filters requests appropriately (this filter would be mapped to url-pattern /*). This is far less efficient than the Coyote solution, because you will reject requests further along the processing pipeline that you need to, but this approach is portable. - Attack the problem with clustering: install more tomcat instances and a load balancer, ideally one that can assign weights to your workers and direct requests to workers according to headers. (The balancer webapp that ships with tomcat 5 has a request header rule that will let you redirect requests based upon header values -- you'd have to add the load recognition capability).

RE: Invoking script from TC 5.0.16
Howdy,
Specify the full path to chmod. Your Runtime.exec calls will only have
a
limited environment inherited.
If you're not running tomcat explicitly with a security manager, you
don't need to worry about the policy as it's not consulted anyways. Of
course, since you're running tomcat as root we can only assume you don't
care much for security.

RE: Mapping /BAH/ to /
Howdy, That's a context path clash: you need to ensure unique context paths for your apps across hosts. For example, use reports and reports2, or salesReports and itReports, or whatever, as long as they're different. Keep the two hosts with separate appBases (which can be absolute directories if you wish, BTW, or relative e.g. webapps/IT and webapps/Sales).

EG, if I deploy reports.war in the first (default) deploy directory of webapps, I can access it at http://localhost:8080/reports but if I only deploy reports.war in the secondary deploy directory (without putting it in the first), going to the same URL returns nothing.

Tried this and it doesn't quite work for me. In my server.xml, I have one Host defined. Setting its appBase=BAR simply requires all webapps to be in the $TOMCAT_HOME/BAR directory instead of the $TOMCAT_HOME/webapps directory. The user (at the browser) sees none of this since the path to a webapp is not http://localhost:8080/webapps/myApp.war but is instead http://localhost:8080/myApp.war. Thus, changing the appBase has no effect on what the user sees, only where the files are stored. I must have worded my question wrong. Say for example, we have mycompany.com who has two divisions - Sales and IT. Each wants to use JSP / Servlets, but they want different deploy directories and different paths visible to the user. Thus, sales wants all of its webapps to be at http://mycompany.com:8080/Sales/someSalesWebapp/foo.jsp http://mycompany.com:8080/Sales/anotherSalesWebapp/foo2.jsp Whereas IT wants all of its webapps to be at http://mycompany.com:8080/IT/someITWebapp/bar.jsp http://mycompany.com:8080/IT/anotherITWebapp/bar2.jsp Sales people can copy their .war files to the $SALES_DEPLOY directory and their webapps will be deployed to the /Sales/ space. IT people can copy their .war files to the $IT_DEPLOY directory and their webapps will be deployed to the /IT space. Is such a configuration possible? :) All advice has and will be a huge help.

RE: odd subclassed-servlet behavior
Howdy, OK ;) If/when you want us to help with the code, feel free to ask. There are no known problems with tomcat skipping steps in the class hierarchy or invoking the wrong class, e.g. a superclass instead of a subclass. It would be a JVM rather than a Tomcat problem anyways. One time I thought that was happening, I misspelled a method in the subclass ;) Check for that, and use instanceof to check the actual runtime class of your objects if you need to ascertain it.

I have just upgraded from JBoss/Jetty 3.0.4 to JBoss/Tomcat 3.2.3, and have noticed some rather odd behavior. I have 3 servlets: SuperClazz |--- SubClazz |--- SubSubClazz SuperClazz subclasses HttpServlet but is not meant to be called directly, but SubClazz and SubSubClazz are both standalone servlets and I call them directly depending on what I need. SubClazz does general things, and SubSubClazz does more specific things. SubClazz delegates to SuperClazz and SubSubClazz delegates to SubClazz as needed. This was working in JBoss 3.0.4 and Jetty. However, in Tomcat 4.1.29 just now I observed that calling SubClazz directly resulted in SubSubClazz getting the call, then execution tracing straight to SuperClazz, _then_ SubClazz. SubSubClazz was the last thing executing before it failed. (That failure is the thing; SubSubClazz doesn't have what it takes to handle my request, and I don't want it called.) Here is an example of my problem. By calling the URL: http://localhost/myApp/servlet/SubClazz?a=1 I get this output from the running server: 10:23:24,020 INFO [STDOUT] [SubSubClazz.doGet] GOT HERE 1 10:23:24,020 INFO [STDOUT] [SubSubClazz.doPost] GOT HERE 1 10:23:24,020 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 1 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 2 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 3 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 4 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 5 10:23:24,021 INFO [STDOUT] [SuperClazz.doPost] GOT HERE 6 10:23:24,021 INFO [STDOUT] [SubClazz.doPost] GOT HERE 1 10:23:24,021 INFO [STDOUT] [SubClazz.doPost] GOT HERE 2 10:23:24,021 INFO [STDOUT] [SuperClazz.doAThing] GOT HERE 1 10:23:24,023 ERROR [Engine] StandardWrapperValve[SubSubClazz]: Servlet.service() for servlet SubSubClazz threw exception java.lang.IllegalStateException: Cannot forward after response has been committed at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDis patc her.java:368) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispa tche r.java:356) ...bad stuff happening since correct calling order is not happening...

RE: Question on using Tomcat 5 in production environment; using multiple instances or not?
Howdy, It's always about tradeoffs. The poster asked for minimum interference, which I read to say if one webapp crashes, or a JSP does System.exit(), or there's malicious code running, then other webapps should not be affected. There's no way to do that if the webapps are within the same JVM, so separate tomcat instances are needed. As for the per machine part, he has a cluster already, so if you want to keep the above separation on every machine in the cluster (which I would), then that's what you have to do. Whether it's a maintenance nightmare depends on the setup. If you use tomcat out of the box, just changing the port numbers, then probably not. We have dozens and dozens of such tomcat instances. Since they're so stable, monitored by services like Nagios, and hardly ever restarted, it hasn't been a maintenance issue for us at all. And then there's the counter-argument: if you have to explain to your CEO that one little reporting webapp brought down all your other webapps because of a bug and you didn't want to separate them in order to save a bit of maintenance time/money, well, that's a tough sell.

It seems that you could use HttpServletRequest.getContextPath() or parse through HttpServletRequest.getRequestURI() to get the root-relative path of the URL.

Hod did you get that working? -Original Message- From: David Wall [mailto:[EMAIL PROTECTED] Sent: Thursday, January 08, 2004 3:43 PM To: Tomcat Users List Subject: Webapp names and paths within JSPs for images In theory I should be able to take my webapp (starting with the base directory that contains the WEB-INF subdirectory) and deploy it using any name I'd like, so I could easily deploy the same webapp with URLs like http://mydomain.com/ (using the root context) or http://mydomain.com/app1/ or even http://mydomain.com/app2/ etc. However, JSPs can include files using the / root to indicate I'm talking about a file at the top of the webapp directory and that works fine. But images need to include URLs that that aren't processed by tomcat (so it doesn't know about the webapp's base directory), so I have to use names like /images/image.gif or /app1/images/image.gif or /app2/images/image.gif depending on where the webapp was actually deployed. While I can use relative paths for such images much of the time, when using servlets that redirect/forward or whatever, the current directory is not always the same, so you can't just use images/image.gif or ../images/image.gif to make it work. How are people coding their JSPs and servlets that return IMG tags so that the images can always be defined without including the webapp path name?

RE: Question on using Tomcat 5 in production environment; using multiple instances or not?
One additinal remark: In the long term having one instance with multiple webapps can easily become a maintainance and/or qs nightmare. With each webapp in a dedicated instance it's much easier to change versions of libraries or even the vm.

SSL failure with some browsers - Access denied by access control list
Problem: - Making any https call fails with the message Forbidden. You were denied access because: Access denied by access control list.. - The failure happens even accessing https://host:8443/tomcat-docs, while a regular http call succeeds. - The failure happens with some browsers (i.e.: Mozilla) but now with others (i.e.: Internet Explorer, and most versions of Netscape). - The failure appears to only happen when accessing a server on a different box than the one where the browser is running. It has not happened (so far) on the same box as the client. - The failure appears to happen with the Tomcat running on either Windows or Solaris. - The failure is not related to the JDK's Verisign Certificate issue (expired Jan 7). It was happening in December, and it was not corrected by JDK 1.4.2_03. Also, the certificates being used are self-signed according to the Tomcat's default instructions. Questions: - Is this a configuration issue? Or is it a deeper problem with either Tomcat or the browsers? I have not seen many postings out there on this topic, so I assume (and hope) the problem is a dumb configuration snafu. - Is there a know solution? I have not found any on the Tomcat archives, on the Mozilla archives, or even after several exchanges with the Mozilla support people. - Is there any additional information I can provide that might shed some light as to why this is happening? Environment details: - Tomcat version: 5. - JDK version 1.4.2 (both _02 and _03). - Mozilla versions failing (at least 1.4 and 1.5). - IE version succeeding (at least 6.0) - Netscape version succeeding (at least 4.5, 4.7, and I believe one of the 7.x versions). server.xml: (feel free to comment if you see something wrong even if unrelated) Server port=8105 shutdown=SHUTDOWN debug=0 Listener className=org.apache.catalina.mbeans.ServerLifecycleListener debug=0/ Listener className=org.apache.catalina.mbeans.GlobalResourcesLifecycleListener debug=0/ GlobalNamingResources Environment name=simpleValue type=java.lang.Integer value=30/ Resource name=UserDatabase auth=Container type=org.apache.catalina.UserDatabase description=User database that can be updated and saved /Resource ResourceParams name=UserDatabase parameter namefactory/name valueorg.apache.catalina.users.MemoryUserDatabaseFactory/value /parameter parameter namepathname/name valueconf/tomcat-users.xml/value /parameter /ResourceParams /GlobalNamingResources Service name=Catalina Connector port=8089 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false redirectPort=8443 acceptCount=100 debug=0 connectionTimeout=2 disableUploadTimeout=true / Connector port=8443 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false disableUploadTimeout=true acceptCount=100 debug=0 scheme=https secure=true clientAuth=false sslProtocol=TLS / Connector port=8109 enableLookups=false redirectPort=8443 debug=0 protocol=AJP/1.3 / Engine name=Catalina defaultHost=localhost debug=0 Logger className=org.apache.catalina.logger.FileLogger prefix=catalina_log. suffix=.txt timestamp=true/ Realm className=org.apache.catalina.realm.UserDatabaseRealm debug=0 resourceName=UserDatabase/ Host name=localhost debug=0 appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Logger className=org.apache.catalina.logger.FileLogger directory=logs prefix=localhost_log. suffix=.txt timestamp=true/ /Host /Engine /Service /Server Bruno Melloni eBusiness Application Center, Americas Nokia, Inc 6000 Connection Drive, Mailstop 4w223 Irving, TX 75039 USA *Office: +1 (972)894-6120 *Cellular: +1 (469) 939-1067 * SMS: [EMAIL PROTECTED] * e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tomcat 5, Apache2 and mod_jk2 integration problem
Hi I am running RedHat 9 with Tomcat 5.0.16 and Apache 2.0.48 and trying to get mod_jk2 to work so that I can use apache as the server and just pass jsp and servlet requests on to tomcat. In order to get tomcat to auto-generate the apache configuration files I have had to take tomcat-jk2.jar from the most recent nightly build (to get ApacheConfig.class) - see bugzilla bug report 25838 and its resolution. I eventually managed to get mod_jk2 to compile (using configure, make etc - not ant) and put mod_jk2.so and jkjni.so into apache/modules directory (and added the LoadModule to httpd.conf). Below I have pasted in my server.xml, workers2.properties and jk2.properties files which at least get apache and tomcat to both start without errors. My problem is that when I try to open /jsp-examples/ through apache, I get the following message in the browser : The servlet container is temporary unavailable or being upgraded along with an Internal Error (500), and in the catalina.out file I get : Jan 9, 2004 1:53:58 PM org.apache.tomcat.util.threads.ThreadPool$ControlRunnable run SEVERE: Caught exception (java.lang.NoSuchMethodError: org.apache.coyote.Request.localName()Lorg/apache/tomcat/util/buf/MessageBytes;) executing [EMAIL PROTECTED], terminating thread in the apache error_log file is the following : [Fri Jan 09 13:53:58 2004] [error] msgAjp.receive(): Bad signature 00 [Fri Jan 09 13:53:58 2004] [error] channelSocket.receive(): Bad header [Fri Jan 09 13:53:58 2004] [error] workerEnv.processCallbacks() Error reading reply [Fri Jan 09 13:53:58 2004] [error] ajp13.service() ajpGetReply recoverable error 12 I have turned on as much logging as I can find and the jk2.log from mod_jk2 doesn't log anything after it has started up. However, I still have tomcat listening on port 8080 and the /jsp-examples/ works fine through there. From the contents of the log files I think mod_jk2 is working OK and passing the request on to Tomcat, but tomcat is failing to process the request - have I missed a step somewhere ? I have experimented with [uri: ...] entries in workers2.properties and with the Context tag in server.xml but haven't succeeded yet - can anyone help please ? Thanks for your time.

Tomcat Deadlock
I'm having a weird problem with Tomcat locking up. I have a couple of functions on my site that rely heavily on transactions. To do a simple load test, I picked the function that hits the database the most and opened that same page in two different browser windows. I hit the submit button at roughly the same time, and waited. It appeared that both browser windows stalled. I looked at the processes in SQL Server (2000) and it said that all of the processes for the app were sleeping, and the two being used were sitting on insert statements for the same table (database deadlock?). I let both browsers sit trying to load for a lot longer than it should have taken for the page to finish, then just closed the windows. After that, the site was no longer accessible. The only way to get it working again was to restart the Tomcat service. Looking at the various log files, the only entry that appears interesting is the following from the site's log: 2004-01-09 10:43:18 StandardWrapper[/WIPT:action]: Waiting for 2 instance(s) to be deallocated I'm using tomcat 4.1.27 with SQL Server 2000 on a Win2K box.

RE: Tomcat Deadlock
Howdy, Can you share your code that serves the page that locked up? Yoav Shapira Millennium ChemInformatics -Original Message- From: Hooper, Brian [mailto:[EMAIL PROTECTED] Sent: Friday, January 09, 2004 11:19 AM To: Tomcat Users List Subject: Tomcat Deadlock I'm having a weird problem with Tomcat locking up. I have a couple of functions on my site that rely heavily on transactions. To do a simple load test, I picked the function that hits the database the most and opened that same page in two different browser windows. I hit the submit button at roughly the same time, and waited. It appeared that both browser windows stalled. I looked at the processes in SQL Server (2000) and it said that all of the processes for the app were sleeping, and the two being used were sitting on insert statements for the same table (database deadlock?). I let both browsers sit trying to load for a lot longer than it should have taken for the page to finish, then just closed the windows. After that, the site was no longer accessible. The only way to get it working again was to restart the Tomcat service. Looking at the various log files, the only entry that appears interesting is the following from the site's log: 2004-01-09 10:43:18 StandardWrapper[/WIPT:action]: Waiting for 2 instance(s) to be deallocated I'm using tomcat 4.1.27 with SQL Server 2000 on a Win2K box.

RE: Tomcat Deadlock
Can just answer the easy one: If a browser is closed in the middle of the request doesn't change the way the request is processed. If the application is waiting on a lock, it will keep waiting. There is just one way to find out if the browser has been closed: write to the output stream (but that isn't very precise due to buffers and caches).

problem connecting Apache2 and Tomcat 5 via mod_jk2
I am receiving a java.lang.ClassNotFoundException for the org.apache.ajp.tomcat4.config.ApacheConfig class. Has anyone experienced this ? Has the ApacheConfig class been changed or had its package changed ? Is there a new Listener class I should be using instead of this one ? I have tried using both the Tomcat 5 source and the binary. I am using build 5.0.16. I tried switching back to tomcat 4 and i can get tomcat running and creating the expected, mod_jk.conf file... but then run into problems with the jk2 configuration on the apache side. It 'appears' like the tomcat 4 version is not creating the right files for use with mod_jk2 (it creates files for use with mod_jk ?) I am really at a loss here.

RE: Tomcat Deadlock
First off, if you have the option you might try using a database pool
instead of using 1 connection for multiple threads (As in Tomcat).
At one company I worked for we had some problems with using 1 connection.
Data would be read/written incorrectly. Results from one query would be
returned to another etc. Bad driver...probably, but it's still a safer and
better use of resources to let Tomcat give you a connection from a pool and
then release it back when you are done.

How does Tomcat 5.0.16 process the keystoreFile tag?
Greetings! I was usingthe keystoreFile tag successfully with Tomcat 4.1.27. However the same tag does not work as expected with Tomcat 5.0.16. Here's the SSL connector code from server.xml: !-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -- Connector port=443 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false disableUploadTimeout=true acceptCount=100 debug=0 scheme=https secure=true keystoreFile=keys/.keystore keystorePass=password clientAuth=false sslProtocol=TLS / The file .keystore is stored in a directory keys located off $TOMCAT_ROOT$ - i.e. C:\jakarta-tomcat-5.0.16\keys\.keystore. For Tomcat 4.1.27 this location worked with the keystoreFile tag shown above. Now with 5.0.16, I get the error FileNotFoundException. If I remove the keystoreFile tag, then 5.0.16 looks for the .keystore file in C:\Documents and Settings\Richard\.keystore. If I put .keystore there, 5.0.16 works perfectly. So my question is - How does Tomcat 5.0.16 parse the keystoreFile tag? Where is Tomcat 5.0.16 expecting to find a file called keys/.keystore?

Subject: RE: Tomcat Deadlock
The code itself is pretty long. Maybe it would be better if I explain
how I handle database connectivity (which I'm guessing has some flaws),
and I know I should be encapsulating my queries in EJB's, but for now I
just have a lot of inline SQL in my Actions. I use a DatabaseManager
class (at the end of the e-mail) to connect to my database. If an
action needs to connect, it makes a new DatabaseManager object. It uses
the methods in the class, then at the end it calls a function to clean
up the connection, etc. Here is the code for the database manager
class:
package WIPT;

private DataSource ds;
// The connection

// The callable statement (for stored procedures)

// If transactions are being used or not

RE: Tomcat Deadlock
Take a look at this.
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-how
to.html
Every time you load a page open the connection, then close it to release it
to the pool. That way each thread should get 1 connection.

I thought I was by defining the data source (using
org.apache.commons.dbcp.BasicDataSourceFactory) in my server.xml file
and using JNDI to access it?

First off, if you have the option you might try using a database pool
instead of using 1 connection for multiple threads (As in Tomcat).
At one company I worked for we had some problems with using 1
connection. Data would be read/written incorrectly. Results from one
query would be returned to another etc. Bad driver...probably, but it's
still a safer and better use of resources to let Tomcat give you a
connection from a pool and then release it back when you are done.

I followed the example for Tomcat 4.x when I set it up. The only reason
I have a separate object is to hide some of the complexity. I'm pretty

Every time you load a page open the connection, then close it to release
it to the pool. That way each thread should get 1 connection.

First off, if you have the option you might try using a database pool
instead of using 1 connection for multiple threads (As in Tomcat).
At one company I worked for we had some problems with using 1
connection. Data would be read/written incorrectly. Results from one
query would be returned to another etc. Bad driver...probably, but it's
still a safer and better use of resources to let Tomcat give you a
connection from a pool and then release it back when you are done.

The code itself is pretty long. Maybe it would be better if I explain
how I handle database connectivity (which I'm guessing has some flaws),
and I know I should be encapsulating my queries in EJB's, but for now I
just have a lot of inline SQL in my Actions. I use a DatabaseManager
class (at the end of the e-mail) to connect to my database. If an
action needs to connect, it makes a new DatabaseManager object. It uses
the methods in the class, then at the end it calls a function to clean
up the connection, etc. Here is the code for the database manager
class:
package WIPT;

Hrmm... Do you create a new instance of the DatabaseManager class during

For some strange, wacky reason I thought you were using it almost as a
singleton. If that's not the case then you probably are doing the right
thing with that, and I am just talkin fluff.

First off, if you have the option you might try using a database pool
instead of using 1 connection for multiple threads (As in Tomcat).
At one company I worked for we had some problems with using 1
connection. Data would be read/written incorrectly. Results from one
query would be returned to another etc. Bad driver...probably, but it's
still a safer and better use of resources to let Tomcat give you a
connection from a pool and then release it back when you are done.

RE: Tomcat Deadlock
I do create a new instance, but each instance grabs a connection from
the pool instead of making a new connection. I think this is ok. Maybe
my problem is with SQL Server locks instead of anything on the tomcat
side. It just seems like something on the tomcat side should timeout
instead of locking up the server. If I assume that it's a deadlock in
SQL Server (and for some reason SQL Server isn't reporting it), can
anyone think of a reason why tomcat would not respond? The connection
pool still has connections available. It could be that tomcat isn't
really hanging. I have a filter set up that checks to see if the user
is authenticated, so the database is hit before every page request.

problem connecting Apache2 and Tomcat 5 via mod_jk2
I followed suggestion from an email on this list and got the latest tomcat-jk2.jar so that timcat had the needed org.apache.jk.config.ApacheConfig implementation. The problem I am having now is thet mod_jk.conf file that is auto generated by tomcat does not seem to be correct. I have read in many places that the module it tries to load jk_module needs to be renamed to jk2_module. However this cannot be done in the same file since it is regenerated each time tomcat starts. Should I not add this line to the httpd.conf file in apache: Include /usr/local/tomcat/conf/auto/mod_jk.conf also... if i do switch the LoadModule command to jk2_module, it then bombs on the JkMount command. Is this build of tomcat not creating a useable mod_jk.conf ? should I ignore this .conf file and simply add all the needed entries to the httpd.conf. If so, is there a document outlining all the needed entries here in order to properly mount different servlet zones so apache can contact tomcat when needed ? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Howdy, 1. I am passing the JProfiler parameters through my JAVA_OPTS in Catelina.sh and when I also try to set my heap size and/or garbage collection parameters tomcat doesn't seem to start. It works fine with one or the other. There are some invalid combinations of the Java VM Options.

I've checked and followed the code of the listen event in ReplicationListener.java Here's what happening: selector.select(timeout) - return immediatly with one SelectorKey available That key is not Acceptable and not Readable so it immediatly skip those IFs and loops back to the beginning. I've put traces and this is executed once every millisecond hence the 100% load on the server. Just to make sure, I've put a Thread.sleep(10) at the end of the loop and the CPU dropped back to 0% and the replication still worked nicely but probably a little slower since the wait of 10ms. I don't know much about those NIO packages but seams like the select(timeout) method shouldn't return a SelectorKey of that state. with any waiting. Let me know what you can dig from those.

RE: Tomcat JProfiler
To make JProfiler work properly with tomcat you need to add
agent.jar in tomcat´s CLASSPATH!
#TOMCAT_HOME/bin/startup.sh
JAVA_OPTS=-Xint -Xrunjprofiler:${PARAM_JPROFILER}
-Xbootclasspath/a:/opt/jakarta-tomcat-4.1.18/bin/agent.jar

Assunto: RE: Tomcat JProfiler
Howdy,
1. I am passing the JProfiler parameters through my JAVA_OPTS in
Catelina.sh and when I also try to set my heap size and/or garbage
collection parameters tomcat doesn't seem to start. It works fine with
one or the other.
There are some invalid combinations of the Java VM Options. I don't
think there's an exhaustive list, but the VM will give you an error
(Could Not Initialize Virtual Machine or something like that). This is
not a tomcat problem.
2. If I shutdown tomcat the Jprofiler process will not shutdown
unless I manually kill it.
Again, not a tomcat problem. Contact the JProfiler folks if you think
the above is an issue.
