SynchronizerToken pattern
We recently brought a Tapestry app into operation, about 80 pages
and components.
My colleague Bernhard Woditschka implemented the SynchronizerToken
there from "Core J2EE Patterns" by Alur, Crupi and Malks
(http://www.refactoring.com/catalog/introduceSynchronizerToken.html),
addressing the following issues:
- prevent use of browser "Back" button
- prevent multiple concurrent submissions of a form
- prevent operation in multiple browser windows using the same HTTP session
The implementation is 100% server side, and it is somewhat strict in
that upon detecting disallowed action on any page, an error page is
activated in any case.
Design summary:
---
The Visit object holds a FlowSynchronizer object responsible for
generating and comparing a unique token.
On every protected page, a hidden field is included in the form:
This field holds a token which is generated by the FlowSynchronizer
when the page is rendered.
Upon form submission, the token parameter passed with the form is
compared to the token recently generated. A discrepancy triggers a
FlowSequenceException resulting in the Exception page rendered.
A match consumes the token so a subsequent duplicate submission fails.
The Exception page renders, depending on the exception thrown,
either the general error text, or an error text specific to the
FlowSequenceException.
Feel free to utilise or comment on this posting.

registering Tomcat as service
Hello, I installed Tomcat, formally run from the console. I am now trying to get it to run as a service. I have in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tomcat\Parameters: JVM Option Count REG_DWORD0X0004 (4) JVM Option Number 0 REG_SZ-Xms256m JVM Option Number 1 REG_SZ-Xmx512m JVM Option Number 2 REG_SZ -Djava.class.path=C:\eCommerce\Tomcat-4.1.30\bin\bootstrap.jar;C:\eComme rce\Tomcat-4.1.30\common\lib\servlet.jar;C:\j2sdk1.4.2_04\lib\tools.jar JVM Option Number 3 REG_SZ -Dcatalina.home=C:\eCommerce\Tomcat-4.1.30 the paths are correct (JDK/Tomcat) but when I try to start Tomcat from the service window, I get a popup: "The Tomcat Service on a Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service" The service does not subsequently run. Now my service may not have any work to do, but I most certainly do. Any info is much appreciated. Paul.

You can telnet to the listener's port and have it restart your Tomcat process.

RE: contextInitialized being called exactly twice
Hi Yoav, On the same note, I was experiencing the same frustration, but I was not deploying any WAR. Could this be the reason for my 2 * execution, even though I had not packaged my classes into a WAR? Many thanks Paul. Hi I bet it's being called once for each time the context is deployed, and the context is deployed twice because you have autoDeploy on AND an explicit context declaration in your server.xml/conf directory/WAR. Turn autoDeploy off and see what happens. (This would explain the static counter being 1: the counter is static once per classloader repository, you have two of the same context at different paths with different classloader repositories).

setting up multiple realms for apps deployed using ant install task?
How do you set up multiple realms for different
webapps that are installed using ant?
We don't have any context tags in the server.xml
file other than for the manager app.
Our applications are installed using install from our
build.xml in ant:
http://localhost:8080/manager";
username="manager" password="manager"
path="/"
war="file://${build.home}"/>
Then that app becomes the root application running on
Tomcat.
In our server.xml :
But we've got other applications that run as
/appOne
/appTwo
etc.
How would we have these other applications look to
their own realm database for authentication w/o using
tags? And if we do need to use
tags for each application, how do we install using
ANT?
Thanks
Paul

Hi all, I have problem in using RequestDispatcher.forward() from servlets. My knowledge is that even after calling this method servlet continues processing the request and thus executes rest of the service method. But I have seen that if a servlet is forwarding to same servlet it stops responding unable to get a database connection from pool. (I have set maxconncections to 1). Database connection is closed in service method in the finally block which is coming after the forward() statement. What is wrong ?. I am using Tomcat 4.1.27 and JDK 1.3.1.

Severity less - DBCP not closing connection.
I hope it is not posted twice. I wrote this mail in forenoon and when tried
to send internet connection lost. I am retyping everything.
I have seen DBCP not closing a connection if the request is forwarded to
same page in the try block before the request is forwarded. With
sendRedirect no problem. This occurs when the connection is obtained through
JNDI look up datasource. I tested the same code in stand alone java
application using manual pooling which works fine. I am using Tomcat 4.1.27
and DBCP 1.1 (I upgraded it today), JDK 1.3.1 and Oracle 8i.

I work with one connection to test for connection leak and any bottlenecks
in code. It works fine if I put the forward() after the end of finally

so.

[OT] Synchronising database access
Hi, I want to synchronise all database access. There are lots of situations where first first a select query is performed to get the results and then insert/update data. I dont want to implement row level locking or optimistic locking. I just want to synchronise the whole process. Only after a thread completes the entire process other threads can execute the code. How to do it. Do I have to synchronise on Connection or on this or implement SingleThreadModel. I also want to know how much extra time a synchronised block requires than an unsynchronised block.

Re: Severity less - DBCP not closing connection.
Thanks a lot for the info.
I need more explanation. I thought that Tomcat creates a new thread to
serve the new request and continues execution of the current servlet thread
after a forward() or redirect(). Now you mean that only after the forward()
method is completed the control returns to the calling servlet.. If the
servlet to which it is forwareded takes lot of time to complete then what
will happen ?. This is not mentioned in any articles or books that I have
read.

JK2 DLL not loaded.
Hi, I successfully installed JK(isapi_redirect.dll) and is working fine with Tomcat 4.1.27 and IIS5 on Win2k. I tried JK2(isapi_redirector2.dll).(I dont know which is JK and JK2) Followed all steps given at the connectors page but the DLL is not loaded. A red arrow is shown at the left. And no log file output. Does JK2 requires jk2.properties. No setting is made for this in the registry. Also I want akk the static content to be servled by IIS. For this I added a virtual directory in IIS which points to the webapp context docbase. All jsps are served by Tomcat and images served by IIS. But no servlets are working. It is giving a 404 error. The uriworkermap content is given below. How to make servlets work ?. default.worker=ajp13 /app/=$(default.worker) /app/*.jsp=$(default.worker) /app/servlet/*=$(default.worker) Antony Paul. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hello Girish,
You have to set the CLASSPATH environment varaible to include the tomcat

[OT] Writing methods in servlets
Hi all, Is there any issues associated with writing methods in servlets other than the morality of it( I dont use methods in JSP pages). My application uses controller servlets for redirecting requests to different pages based on the parameter(action) passed to it. Application is designed in a way that it will have one controller servlet for a group of actions on same entity. Earlier I used to check the action in if else blocks. Now the servlet is becoming cluttered with lots of if else blocks. So I want to move this to methods and I must do it in Servlets itself (The application design dont allow to move this to another class). I know that container creates multiple threads of servlce method of (I dont know how) same servlet to service multiple requests. Then what about other custom methods in servlets.

Hi all ,
I have some questions for which I was unable to find answers by
Googling. So I am asking it here. It is quite long.
1, Is there any security threat for Tomcat 4.1 series. I am using Tomcat
4.1.27 for development. What is the history of Tomcat in this regard. Is
Tomcat vulnerable to any remote exploitation issues provided that the
application is well written. I want to collect some arguments to favour Java
and Tomcat.
2, Any documentation on how servlet container is creating multiple instances
of same HttpServlet without implementing Runnable interface. At least
provide some links to docs or books which teaches threading issues in
servlet. It is only for a curiousity. I am only an application developer. I
want to improve my knowledge in servlet technology.
3, How to test a servlet for threading issues.
3, Is there anything wrong in implementing logic in service method in a
class which extends HttpServlet. What will happen if a doHead and other
requests are send to it. How to simulate a doHead,doTrace etc.. request ?. I
got some info at http://www.jguru.com/faq/view.jsp?EID=8824
4, Is it possible to synchronise a block of code in a servlet. I mean only
one thread of the same servlet execute the same portion of code at a time
and completes execution. I dont want to implement SingleThreadModel and
there is only one name in web.xml pointing to same servlet class. I have an
idea. Is this right.
Create a synchronised block which synchronised on the class.
synchronized(AlertServlet.class){
---
}
My purpose is to synchronize database access. The application dont have
a heavy load.
5, Is it secure to transfer a request and response to another object which
is created in the service method of a servlet ?. I believe it is a safe
approach. I think Struts is doing this.
6, I have seen that Tomcat not shutting down the threads which are active
when shut down command is issued. I used to kill Tomcat in such conditions.
Does Tomcat will ever kill this threads if they are not completed execution.
What criteria is used in such cases.
7, In Tomcat 4.0.x series there is one file catalina.out which prints the
number of active Httpprocessor active(I think it is number of threads) ut it
is not found in 4.1 series. Is there any way to get this log file in 4.1. I
also want to writing to this log mailed to me when the no. of HttpProcessors
exceeds a limit without tweaking Tomcat code.
rgds
Antony Paul.

[OT] Quality of open source code - not a survey.
Hi, I am not questioning quality of opens source projects. My intention is to learn from looking at the source code of open source projects. I want to know whether it is good to learn from looking at the source code of this kind of projects. I want to develop best coding practices and know how things work and how to implement it. To learn it, the cheap way available to me is looking at code written by some experts. I believe people who wrote Tomcat,JSTL and other have godd knowledge of Java.

Re: Need some Tomcat Configuration help badly
Is your problem solved. I have noted one thing about Tomcat. If the compiled classes modification date is less than that of the machine running Tomcat, Tomcat will never know that the file is changed and never reload it. Only a reload can load the new class. This is true for servlets,beans nad JSP. I faced this problem when workstation machine time is behind server time. You can overcome this by syncing all machines clocks. Or advise students to perform a reload through the manager task. Or write an Ant script to reload it. rgds Antony Paul. - Original Message - From: "Dick Steflik" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Monday, December 15, 2003 5:24 AM Subject: Re: Need some Tomcat Configuration help badly > I had the same question.

Re: RequestDispatcher in servlet is not working
It is what I said IllegalStateException.. It is caused by writing to a PrintWriter or writing the headers. You can avoid this by not writing to the PrintWriter and not setting any response headers. You dont need to write to out if you are forwarding a request. Write to StringBuffer() then write to out if not forwading. Another way is increasing the buffer size of out.

tomcat 5 source compiling error
Hi all, I am trying to compile Tomcat 5. I downloaded the source and followed the directions in building.html at jakarta site. Problem is I am using JDK 1.3.1. I is giving some error messages. 1, One is related to JAAS. I downloaded JAAS and JSSE. JSSE is put in base.path(usr/share/java). I am on win2k. But where to put JAAS ?. Currently I put this in jre\lib\ext. Where is the suitable place for this. I dont want to put it in ext directory. I want to know which program is using which libraries. 2, javax.xml.transform.TransformerFactoryConfigurationError: Provider for javax.xml.transform.TransformerFactory cannot be found This one I cannot find a solution. Googling said that ant 1.5 doesnt have XSLT transformer and says to download and use xalan. Then what is xerces-2.5.0. If using xalan where to put it.

Re: Can't run servlets
You have to declare the url mappings for servlets. Do this after all servlet
declarations. Like this
TestingServlet
TestingServlet
TestingServlet
/TestingServlet
Another way is using the invoker servlet provided by Tomcat. If using
invoker servlet no need of servlet mapping. But it have security bugs and is
disabled by default.

What after reloading a context

[OT] custom tags in a page
Hi, I wrote two custom tags. One is used only once in the page(msgtag) while the other one is used multiple times(outtag) similar to JSTL c:out. Both classes extends BodyTagSupport. When I looked at the compiled servlet code both tags are called in different ways. Each use of msgtag is made a method call. If I put 2 msgtag(both are exacly same) in JSP it creates 2 methods. outtag is invoked directly in servlet. Why the difference ?. Is this behavior can be controlled through coding ?. Which one is better ?. Why Tomcat is creating one method per each tag invocation.? Why not manage it like an object. Each time it is getting an instance from a pool ? BTW Extending TagSupport or BodyTagSupport is better. I have no need to process the body ? Any performance gain ? rgds Antony Paul - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [OT] custom tags in a page
Thank you for the reply. 'msgtag' don't have attributes. The other tag 'outtag' have attributes and it is invoked in service method itself . No tags are nested. But I cannot understand the logic in creating a separate method call for each tag invocation. In each method it is using same code other than the retrieved tag instance is assigned to a new variable and methods are invoked on this. Is there any particular reason for doing this ?. My reason for asking this question is to know and learn how pooling works. rgds Antony Paul - Original Message - From: "Bill Barker" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, December 30, 2003 11:36 AM Subject: Re: [OT] custom tags in a page > Easy question first: If you don't need BodyTag, don't use it, since it is a > potential memory hog.

No Java compiler was found ....
Hi all, I am using Tomcat 5.0.16(for testing purpose only). When a page is having an error like missing semicolon or a special character in code it is giving the following error in browser. org.apache.jasper.JasperException: Unable to compile class for JSP No Java compiler was found to compile the generated source for the JSP. This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK to the common/lib directory of the Tomcat server, followed by a Tomcat restart. If using an alternate Java compiler, please check its installation and access path. org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandl er.java:127) org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java: 351) org.apache.jasper.compiler.Compiler.generateClass(Compiler.java:415) org.apache.jasper.compiler.Compiler.compile(Compiler.java:458) org.apache.jasper.compiler.Compiler.compile(Compiler.java:439) org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java: 552) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java: 291) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:301) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:248) javax.servlet.http.HttpServlet.service(HttpServlet.java:856) Interestingly it is printing lots of lines in console including the classpath and the actual error(; expected). I am using it on Win2k SP4 machine which have both JDK1.3.1 and 1.4.1 installed. I compiled Tomcat from source. I remember that JDK 1.4.1 is used for compiling Tomcat and in startup.bat I have set the JAVA_HOME and CATALINA_HOME to JDK1.4.1.

The generated servlets are not put in a package. When Tomcat is compiling JSP it is put in org.apache.jsp. How to set this in the jspc task.

Re: Problems running pre-compiled JSP classes when in subdirectories
The problem is when files are kept in work directory. I dont want to put the generated files in web-inf\classes and add mapping. My purpose is to compile jsp pages as part of a build before the application is given for testing. I will keep files in work directory. This I have to do frequently and I want to detect any compilation errors and make it faster for the QA fellow to access the application.

contexts
Hi, I have two apps running under different contexts. They both link to each other. I have defined in the server XML thus: Why when I link to the one from the other does the desired URL appear as if it has loaded, but a bastardization of the original remains? The original being the app that called the other with all manner of unpleasantries displayed in the browser. How may I configure the server.xml to link across apps under different contexts please? Presuming it is a context issue of course. Thanks Paul Wallace - 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 ?

Help with Active directory authentication in tomcat 5
I am trying to authenticate web users against an active directory
instance, but for some reason the configuration that worked in tomcat 4.1
is not working in tomcat 5.0.18
Here is the message that I get from the realm authentication with
debugging turned on:

It appears to successfully authenticate the user, but does not find the
roles. In tomcat 4.1 I get very similar information, but it returns 1
role which is the correct behavior. I also noticed that instead of "("
and ")" the log is showing "\28" and "\29". Is this part of the problem?
Here is the server.xml excerpt that I am using:
ldap://dev:389";
userBase="cn=users,dc=development,dc=com"
userSearch="([EMAIL PROTECTED])"
userRoleName="member"
roleBase="cn=users,DC=development,DC=com"
roleName="cn"
roleSearch="(member={0})"
connectionName="CN=user,CN=users,DC=development,DC=com"
connectionPassword="pass"
roleSubtree="true"
userSubtree="true" />
The same realm configuration seems to work fine for tomcat 4.1 but can't
find the roles in 5.0.18.
Can anyone help me?
Thanks!!

Rollover Web Certificate
Hi, Wondering if anybody has experienced a web cert expiring in their keystore. If so, I was wondering how you go about replacing it without bringing down the server. Can you simply create a new certificate (in a different keystore, I'd imagine) then get it signed via the CSR, then import the new one into the original keystore, overwriting the current about-to-expire certificate? I don't think this would work though because the private keys would be different in the two keystores. So you'd have to do this whole process in a new keystore and then bounce Tomcat and have it point to the new keystore.

PKCS12 Keystore
Hi, I'm trying to setup a keystore of type pkcs12 using the java keytool. I enter this command 'keytool -genkey -keystore c:\tomcat -storetype PKCS12 -alias tomcat'. Well, everytime I try and enter in the subject information for the keys and finish the process, the keytool creates the keystore of type pkcs12 but I get this error message 'keytool error: java.io.IOException: PKCS 12 storing not implemented' Do I have to download an additional provider or what?

dirty data and session management....
This may be more of a design question, but I'm wondering if tomcat has anything in it's API that we might be able to leverage to help manage dirty data in a user's session? When our user's login, we load, into their session a w3c dom document that contains user-information, etc. We use xsl transforms for display, so we overload that session-based w3c dom w/ information necessary to show the page to the user (any name value pair that could have been read from the dB, say "roles") So, User-1 is editing the roles. We read from the db, the id/name for each role, tack it into the session XML and transform it on the XSL to display to the user. User-2 does the same thing. User-1 edits some of the role names and submits. User-2 does the same thing, thus making User-1's role information dirty. Is there a way (using some API or tomcat) to enforce that User-2's submit cannot take place w/o them re-reading those roles b/c User-1 already committed? Additional side question, also related: How do you prevent this behaviour using objects in memory in servlets w/o using synchronized objects? (possible in tomcat using something in the tomcat framework?) Thanks in advance. __ Do you Yahoo!? Yahoo!

transitioning from non-logged in to logged in using security constraint....
What does tomcat do to ensure that you're logged in while using the j_security_check ? We're trying to transition users from non-logged in to logged in, but we've got a fair amt. of portions of the site that should be accessible from both states (non-logged in and logged in) Is there something, programmatically, that's done, or is it something that tomcat simply places in the user's session? any advice or direction to the location in the API would be great. thanks __ Do you Yahoo!?

RE: Problem using JNDI/DBCP to get DataSouce
Some progress but still not working. 1. Using my connection parameters I can open a connection to the database in the standard JDBC way. 2. I have to moved the DataSource configuration from GlobalNamingResources to the apps Context area of server.xml. This seems to have allowed the JNDI look-up to work. I now get a DataSource instance with sensible contents. 3. But when I ask for a connection it throws "Cannot get a connection, pool exhausted" with a nested exception "Could not create a validated object" Beginning to think it's not me but the tomcat server. I'm now moved to 4.1.24 to 4.1.30 but no improvement :( - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Problem using JNDI/DBCP to get DataSouce
Tried
dataSource = (DataSource) initContext.lookup("java:comp/jdbc/OscarsDB");
But it return null, so tried
dataSource = (DataSource)
initContext.lookup("java:comp/env/jdbc/OscarsDB");
And a datasource instance was return so before, looking good...
However, still got the same exception when trying to get a connection
instance
"Cannot get a connection, pool exhausted"
with a nested exception
"Could not create a validated object"

RE: Problem using JNDI/DBCP to get DataSouce
I agree, but it looks good and I've tried without one being specified. In
addition, I've never see a connection raised at the database server end.
This makes me think the DataSource is just not working and I'm not seeing
the proper error. But I can find nothing more in the logs :(

RE: Problem using JNDI/DBCP to get DataSouce
Fixed at last! And of course it's and annoying fix. I've been using these Informix JDBC 2.0 drivers for some months without problem. As a last resort I downloaded the very latest version from the IBM site and... The rest is now history :) Many thanks to ALL your help.

jspc
Hello, I have compiled my JSPs thus: jspc -webapp C:\src\site -d C:\src\site\classes -s -l -uriroot C:\src\site this builds the Java source files to the specified location, but how might I deploy them? What is a typical deployment after a JSP compilation? Compilation of Java source files, then WAR/JAR? Can I not define the JSP compile to go under my work directory? The purpose of my efforts is to try and speed up / make TC less memory consumptive. cheers Paul.
RE: jspc
Hi Jason, Thanks for that. Yes, it does make Paul, I just use the -compile option and have jspc do the compilation from .java to .class for me. It seems to work fairly well. Once all the fully compiled (ie .class) files are placed in you applications WEB-INF/classes directory you just need to place the generated web.xml file in WEB-INF. There is an option to create a complete web.xml file that you can place in WEB-INF or, if you already have a web.xml file you want to keep, you can have jspc create an xml fragment that just contains the servlet definitions and mappings that you then add (in the appropriate place) to your existing web.xml. Then just war up you application directory in the normal way (you can even delete the jsps once your certain the servlet mappings are working). If you try to put the generated files in your working directory you won't be able to war them up and deploy them in the normal "put war file under webapps directory and tomcat will expand it when it starts" way. You'd have to ship a complete tomcat directory structure with the work directory already filled in with your compiled jsps. Does that make sense?

RE: jspc
(sorry, wrong key!) Hi Jason, Thanks for that. Yes, it does make sense. A couple of things though, I just ran it with -compile - great. But my query about the work directory and was more towards what I am being 'encouraged' to do from the powers that be. I.e not WAR the app., but put it in the work directory. Is this ill-advised/poor practice? To accomplish this, is it as simple as dragging the compiled source under my work directory, and modifying my web.xml as advised? Why does -compile work, but not appear in the usage?! Also, can I specify a path for the compilation, rather than the classes be placed in the same dirs as the source? (I tried adding a path after the -compile switch, but it constructed and compiled a file with the same name as the class directory destination). Do I make sense?! Paul.

RE: jspc
Hi, Yes..that is what I thought, but I learned from a 'reliable' source I could accomplish this on saving overhead. So rather than looking into the whys and whats, I looked into how to do it, and look into the performance benefits later. I will provide the list with my sources reasoning, when it becomes available! A thought..and to answer a question with a question (Why would you precompile jsp files?), why is jspc there? If only to increase performance on the first hit? Thanks Paul. It will increase speed on the first viewing of the jsp, but after that I can't see how there will be any difference. How much memory can you save if any? And how would that work?

RE: jspc
Hi Jason, Yes, it was of help. Thanks for your lengthy insight. Paul. Hi Paul, To specify a path for your compilation results use the -d option like so: jspc.sh -compile -d /jakarta-tomcat-5.0.25/webapps myapp/WEB-INF/classes ...the rest of you compile options... It will build any subdirs required using the directory you specify, along with the package name you give it (org.apache.jsp if you don't specify a package name) as the root directory for any subdirs. As for the work directory that is where Tomcat places any jsps that it has to compile (i.e. non-precompiled jsps) during runtime. If you run Tomcat with uncompiled jsps and walk though your app in a browser you will see compiled JSPs appear in the work directory. It will create subdirs, etc. to mimic your applications directory structure and place compiled versions there. You could just place your compiled jsps in the same respective places in the work directory before starting Tomcat and it would probably work. BUT, Tomcat will only expand .war files into the webapps directory so you have no way of packaging up these compiled files from the work directory and automatically expanding them into another work directory at Tomcat startup. That would have to be a manual process by the end user (or an install script). It is not the recommended deployment strategy. It does save you from having to worry about having the web.xml mappings correct though. Tomcat will check first in the work directory for a compiled jsp and then look for an uncompiled version if it doesn't find one there. No mappings in web.xml are required. In answer to another related question I saw posted: If you precompile your JSPs and then remove the original JSPs you need to have two things for your app to run: 1. The compiled JSP class files need to be copied over to the WEB-INF/classes directory with the correct directory structure. (The exact directory with be the package name (org.apache.jsp by default) plus any subdirs the JSP existed in under you apps root folder. i.e. if under webapps/yourapp you had a jsp in a directory subdir1/subdirB then under you WEB-INF/classes directory you would need a directory called org/apache/jsp/subdir1/subdirB and you would place that compiled JSP class there. The easiest way to do this is to run your compile with the -d option as stated above and point the output to your WEB-INF/classes directory. jspc in Tomcat 5.x should automatically create the correct subdir structure and place the class file in it. 2. Yuo need servlet definitions and mappings that tell Tomcat "If someone requests this .jsp execute this servlet instead". These go in the web.xml file for your app. jspc will create a complete file or just a fragment file that contains all the mappings. You can tell it explicitly to create a fragment file with the -webinc option like so: -webinc /jakarta-tomcat-5.0.25/webapps/myapp/WEB-INF/my_web_fragment.xml I think it creates a complete web.xml if you use this option -webxml /jakarta-tomcat-5.0.25/webapps/myapp/WEB-INF/my_complete_web.xml In this case you just have to rename the file web.xml and place it in you app's WEB-INF directory. If you don't do BOTH of these things, then Tomcat won't know where to look for your compiled JSPs and will instead look for the actual .jsp. Finding nothing it will throw a 404 error. I hope this is helpful. Jason --- Paul Wallace <[EMAIL PROTECTED]> wrote: > (sorry, wrong key!) > > Hi Jason, > Thanks for that. Yes, it does make sense.

queueing concurrent server requests
Hi All, Can someone point me in the right (any) direction towards info on queuing concurrent Tomcat server requests? I propose to queue concurrent requests to Tomcat, if they exceed a given number. Where might I find documentation, or any other resource, to assist? thanks Paul.
Re: Session Replication w/o Multicast
You could save your sessions in an RDBMS, but I'm not sure how responsive this would be... Jeremy Nix wrote: Is there currently a way of replicating session information across multiple tomcat nodes without multicasting? If not, has any extended the Tomcat API to support this? The reason I ask is because we are using a hardware load balancer, and it does not support multi-casting. One thought is that we could upgrade our hardware to a load balancer that supports this (not sure one even exists), but I'm sure that there are other means of performing replication besides multicasting. Using a database as the session persistence layer is one thought. Direct tomcat node to tomcat node in memory session replication is another thought. Just thought I'd see what ideas/solutions are out there. _ Jeremy Nix Senior Application Developer Southwest Financial Services, LTD. (513) 621-6699 x1158 www.sfsltd.com
TC 5.0.27 startup problem
Hi, A seemingly simple one, but not for I! I am trying to setup the above version of TC on Win XP. My JAVA_HOME is set as an environment variable, and in the top of my startup.bat I am setting CATALINA_HOME: "rem $Id: startup.bat,v 1.6 2004/05/27 18:25:11 yoavs Exp $ rem --- set CATALINA_HOME=C:\dev\jakarta-tomcat-5.0.27 rem Guess CATALINA_HOME if not defined set CURRENT_DIR=%cd%" When running this file from the command prompt I get: "23/07/2004 16:14:25 org.apache.coyote.http11.Http11Protocol init SEVERE: Error initializing endpoint java.net.BindException: Address already in use: JVM_Bind:8080 at org.apache.tomcat.util.net.PoolTcpEndpoint.initEndpoint(PoolTcpEndpoint. j at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:137)" I immediately looked at what was using port 8080 (nothing to my knowledge) and this was confirmed. I ran netstat which confirmed that port 8080 was not in use. TC appears to have started, but http://localhost:8080 (with numerous stacktraces (above)) is showing a 404.

RE: TC 5.0.27 startup problem
Hi & thanks, A reboot sorted it. Netstat is not a reliable means to check what ports are being used by which app then? Regards Paul. You definitively have a process using 8080 : either a tomcat process, still running, or another program (oracle,...) Check all your current process, or simply reboot. -Message d'origine----- De : Paul Wallace [mailto:[EMAIL PROTECTED] Envoyé : vendredi 23 juillet 2004 08:40 À : Tomcat Users List Objet : TC 5.0.27 startup problem Hi, A seemingly simple one, but not for I!

TC 5 - root application
Hi, Using Tomcat 5, I wish to move my application from under webapps, into a defined directory somewhere on the server hard drive. Instead of defining a context for my application, I wish to point Tomcat to my application as ROOT to a generic location i.e http://localhost points to c:\site\index.jsp, for example. I have configured it to be using port 80 already. Thanks Paul. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: My first WebApplication
Hi to you, 1st guess, you should have a dir for your application - WEB-INF, not WEB-IN...unless it's a typo. In that dir make sure your web.xml names and maps your servlet. Give it a go. Paul.
