Why do I need to run IIS6 in IIS5 Isolation Mode
All, I'm a bit confused on why I need to set my IIS6 installation into IIS5 Isolation mode. I have installed the isapi_redirect.dll file as a Filter and Extension in standard IIS6 mode and it all works fine. The version of the dll is 1.2.15 on a Windows 2003 server, connecting to the Embedded Tomcat (5.0) under JBOSS 3.0.27 on a Solaris 8 Sun Server. My concern is that while it may appear to be working, something nasty is going to happen once its in a live environment and being hit a lot harder. Thanks Richard
RE: problem with tomcat 5.5.9
I seem to recall that on RH, all files are mmap'd and that can occupy seemingly huge amounts of memory, when in fact it is all buffer cache and will be collected by the OS if actually needed for something else. Could it be logging in your app (or Tomcat) is writing a lot of data to files?

Problems with custom Realm and class loading (long)
Hi, I hope someone will help with this. I'm running Tomcat 5.5 on the front-end and Jboss 4.0.3 in the back end, running with Java 5. We designed our security module, so I wrote a custom Realm by extending RealmBase. I put the Realm under server/lib. The realm uses a Business Delegate, which in turn uses a Service Locator to get the reference to a remote EJB home interface. Since the Business Delegates and Service Locator are in common utility libraries, I had to put also those under server/lib, otherwise at startup Tomcat said it couldn't find the classes the Realm was dependent on. The realm started fine and I must say...it seemed to work fine. Until the delegate performs a PortableRemoteObject.narrow() on the EJB remote home proxy received by Jboss (Please note! The lookup on Jboss from the Service Locator goes fine, it returns a proxy). Here I get a ClassCastException. Now the funny part. I applied the custom Realm also the the Tomcat admin application, which you know is deployed under server. The same Realm, the same Service Locator and Delegates this time work fine, the EJB remote home is narrowed without problems and I can create a Session Bean component interface. The same classes containing Service Locator and Business Delegates are deployed also within our web apps, in the WEB-INF/lib folder. So we have got those classes under server/lib and under the WEB-INF/lib of all our web apps. I suspect that there may be a classloading issues. But I can't move the realm classes in the shared/lib folder, since Tomcat complains at startup that the realm classes must be in the server/lib folder, so the same classes must be deployed under server/lib and WEB-INF/lib (or shared/lib) of our web apps. How could I solve this problem? Why does the admin app run fine, whereas (note that the realm gets invoked for our web-apps, it's the service locator which generates the ClassCastException) another web-app (under the /webapps folder) doesn't? Is there a way to tell Tomcat that the Realm classes should be searched in another folder than server/lib? (This way I could put the classes in shared/lib and probably I could solve the problem). Thank you for any help.

XML parser advice

I need to develop some XML functionality - basically output the contents of a number of db tables, adhering to an XML schema that I have developed. It's 2 1/2 years since I have done any XML work and I am sure that things have moved on apace since then. What is the best parser to use with TC. Is it still Xerces?

Re: How can I take a webapp temporarily out of service using mod_jk?
Prout John - jprout wrote: Hi I am running a JBoss cluster, using tomcat as the Servlet engine. Apache and mod_jk provide load-balancing of requests over the machines in the cluster I need to be able to replace all the URLs in the webapp with a Temporarily out of service page during maintenance, and I need to do this without making any permanent Apache configuration changes and without restarting Apache (Operations is very reluctant to restart Apache). Does anyone know a way to do this? I think there may be a way to use the controls on the mod_jk status page to redirect all requests for a webapp to a different URL ( the Route Redirect input) but this is probably wishful thinking - even if does allow me to redirect requests, it would probably apply to all the webapps in the cluster, which wouldn't meet the requirement. The status page teases me by listing all the JkMounts and JkUnmounts, but doesn't allow me to change them; adding a JkUnmount dynamically would be a good solution. Any Ideas? John If you have a simple setup (1 tomcat, 1 apache) then you should be able to just update your apache config to comment out JkMount for that specific webapp and do a 'apachectl graceful' command to have apache reload. Make sure you have some pages in your apache where your webapp normally resides to nicely inform the user maintenance is being done and they should come back later. When traffic isn't being diverted to the webapp, they will see the mantenance page. After maintenance is complete, update apache again (reenable JkMount) and do another 'apachectl graceful' command. The user's experience should be very nice with no 404 errors, stack traces, or the like. They may lose their session if they are in the middle of a transaction. Handling session fail-over will require a second tomcat and clustering. -David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: (newb) Tomcat servlet mapping problem
Hmm, you're mixing up that /servlet story. Better remove everything named servlet from your environment... It is only confusing. Create app.xml, put the Context path / or /app, and then /FCLxyzServlet or /app/FCLxyzServlet are the correct URLs. Does that make any sense?

However, it should work depending on Tomcat's security settings. Really? I thought you could do anything within a Servlet that you can do within normal Java code. Also, a restriction on calling the main() method within a class seems nonsensical, because one can simply rename that method. 2.) am I allowed to write files on the disk from within an web application? If I am, something went wrong while trieing ;-) Can i write anywhere or have I to write to my application dir or to temp dir or something. If you wish to be spec-compliant, you can only write to a temporary directory that you ask the context for. However, this may or may not be enforced depending on Tomcat's security settings. This point I'm less sure on, but I would think it's the role of the *servlet container* to be spec-compliant, not the programmer of a servlet. But FWIW, the Tomcat Administration Web Application (separate download in 5.5.x[1]) does alter the XML files located in the Tomcat /conf directory. If the original questioner is having problems altering text files located on the server, perhaps the code for the Admin application would be a good reference for him. Glen [1] http://tomcat.apache.org/download-55.cgi - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] I know this is a late response in this thread, but I think the point is still relevant Writing data is a perfectly normal operation in web applications. Admittedly the servlet spec is centered on writing to a database service instead of the filesystem. Webapp designers need to consider one or two things from the beginning if writing to the filesystem. The first being deployment from a web archive (.war file) is intended to be read-only by the servlet spec. Best practice is to configure a path to a place outside the webapp for writing data. If the data needs to be made available to the client, write a basic servlet to read the data and write it to the client. It'll make updating the webapp sooo much easier when you don't have to worry about sorting out basic material in the webapp from all the uploaded/dynamic material. The second item to consider is path. Relative paths are going to be relative to the current working directory when tomcat was started, not the webapp. It'll cause loads of confusion trying to figure out where that uploaded file went until you realize how the relative path was computed. ServletContext.getRealPath may help if you really want to write to the webapp's folder, but this method only returns a path if the webapp is deployed from an uncompressed folder (not a .war file). Ok. I miscounted. Item three to consider: Writing to the filesystem limits portability. Not a problem if this is intended to be an in-house solution, but might be something to consider when trying to sell your solution to customers. -- David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
stdout/logging
On Windows you can set up tomcat as a service. The program that does this (http://tomcat.apache.org/tomcat-5.5-doc/windows-service-howto.html) lets you redirect stdout and stderror to files (see -StdOutput and -StdError options). Is there any way to accomplish this exact same redirection without running tomcat as a service? That is, I want all the output that typically goes to the tomcat console to go to a file instead. If it is not possible, I am curious as to why? -Sam

Tomcat nightly builds
It seems that the Tomcat nightly build *binaries* are invalid.. I'm looking at the the page: http://cvs.apache.org/builds/jakarta-tomcat-5/nightly/ and the two binary images each contain only 45 bytes. Ultimately, I am looking for the most recent changes to the jsp-examples in *binary or war* format. These changes did not make it into 5.5.15. I assume I will be able to find these changes in binary format when the correct nightly build binaries are created. Any idea when a nightly binary will be available for 5.5.x? Also, here is some additional info from Yoav (from an off list email) on this subject. Yoav Shapira wrote: The binary nightly builds do seem to be broken, and the source ones look out of whack too (way, way too big: the source distro should be a little less than 6MB, instead it's 173MB).

mod_proxy_balancer: how to define failover (only)/hot standby behavior?
Hello, using Apache 2.2.0/mod_proxy_balancer, is it possible to configure a proxy balancer with two balancer members, where one of the two only gets the requests, if the other one fails? In mod_jk that was possible using local_worker_only, but with mod_proxy_balancer I have not yet understood how to define such behavior (defining loadfactor=0 would be a way, probably working right away, but is definded to be a number between 1 and 100). As far as I understand at the moment, it is only possible to define an almost-only-hot-standby-behavior, where the failover-backend gets 1/100 of all requests.. Thanks in advance and best regards, Andreas P.S.: I posted the question to the apache-httpd-users mailing list 3 days ago, but it seems to fit better to here..I would post the answer there, if I got one here.

Re: mod_proxy_balancer: how to define failover (only)/hot standby behavior?
Actually, dev@httpd.apache.org is best, since that is where the development of this module is being done. I have changed the email headers accordingly. A sort of warm standby is something that I had planned to work into the balancer code post 2.2.1. On Jan 24, 2006, at 11:14 AM, [EMAIL PROTECTED] wrote: Hello, using Apache 2.2.0/mod_proxy_balancer, is it possible to configure a proxy balancer with two balancer members, where one of the two only gets the requests, if the other one fails? In mod_jk that was possible using local_worker_only, but with mod_proxy_balancer I have not yet understood how to define such behavior (defining loadfactor=0 would be a way, probably working right away, but is definded to be a number between 1 and 100). As far as I understand at the moment, it is only possible to define an almost-only-hot-standby-behavior, where the failover-backend gets 1/100 of all requests.. Thanks in advance and best regards, Andreas P.S.: I posted the question to the apache-httpd-users mailing list 3 days ago, but it seems to fit better to here..I would post the answer there, if I got one here.

RE: Tomcat upgrade: 3.3.1 -- 5.0.28, hang up after running 1 or 2 days
Thank you for your attention, Glen! These 2 (good and buggy) production tomcat servers run different web applications on different physical machines. Their hardware and operation systems including Windows service packs are same. Tomcat configuration is very similar. The good tomcat server was brand new (new installed operating system, new web application) and started Java 5.0 + tomcat 5.0 at the very beginning. The buggy one started with Java1.3 + Tomcat 3.3.1 and had ran smoothly about 4 years. Regarding the web application on the buggy tomcat 5.0 server. The source code remain the same before and after the tomcat upgrade. The only change is to use the new java 1.5 compiler with option -souce 1.4. Compiling is not a problem. Starting the buggy tomcat 5.0 is not a problem. The only problem is hangup after some user access. All possible changes were minimized during tomcat upgrade. The buggy tomcat server was rolled back to Java 1.3 + tomcat 3.3.1 again last Friday. This rollback did not fix the problem. Yesterday (last Monday) I removed Java 1.5 + Tomcat 5.0 completely. JDK 1.3 + J2EE 1.3 were re-installed. At this point, everything was rolled back to the state before tomcat upgrade. This buggy tomcat server has run okay by far ( 24 hours), but is too early to say it is fixed. If it can behave until the end of this week, I may dare to say it is fixed and the problem is caused by the upgrade. Maybe the co-existence of Java 1.3 and 1.5. Maybe co-existence of Tomcat 3.3 and 5.0.

Re: Do idle servlets get unloaded/reloaded?
Hi Blair,
On Tue, January 24, 2006 2:41 pm, Blair Cooper said:
I have a servlet running on Tomcat 5.5. If it sits idle for a while and
then
I hit it, the init() method gets called again. autoDeploy is set to
false.
Is this expected behavior?
As per the servlet spec, the container can unload and reload a servlet as
needed. It is an expected *potential* behavior. My own personal
experience would indicate it's rare, but you have to design for it.
If this is expected, shouldn't destroy() get called at some point prior to
the init()?
I would expect destroy() to get called at some point before init() does a
second time, but I'm not sure if that is a guarantee of the spec. Seems
like it probably would be though.
The problem I'm having is that the init() method ends up try to recreate
objects that where created by a previous call to init(). My destroy()
method
would have cleaned up the earlier instances if it had been called. I have
logging in the destroy() method so I know that it didn't get called.
Implement some sort of check in init() to determine if it has fired
already or not. A simple static boolean field on the servlet should do
the trick. So, maybe you have:
private static boolean isInitialized;
Then in init(), you do:
synchronized (isInitialized) {
if (!isInitialized) {
// Do initialization tasks.
isInitialized = true;
}
}
Thanks,
Blair

Postgresql and JNDI Datasource
I am trying to define a global JDBC datasource, where the database is Postgresql (version 7.3) ni Tomcat version 5.5.15. I have strictly followed the example in http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html, but it does not work if I define the datasource in $CATALINA_HOME/conf/server.xml. However if I define the datasource in the application META-INF/context.xml, it is working. I would prefer to define the datasource in $CATALINA_HOME/conf/server.xml. Has somebody succeded in doing that ? And if yes, how ? Torben Frøberg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

From Java to C#, ASP.NET [Off Topic]
Hi all, I should mention that this post is a bit off topic. If you hate Microsoft then stop reading now and I'm sorry for wasting your time. I don't own stock in Microsoft, I don't know Bill Gates and nobody paid me or asked me to say the things I wrote below. These are just my opinions based on my experiences with many years in Java and two months of learning .NET/C# 2.0. I've been programming in Java/J2EE for the past 8+ years, most of this time as a contractor for several companies on many J2EE projects. I even have a small (and now hopelessly out of date) Java web site that I've maintained for the past 5+ years at www.absolutejava.com, which will be removed in early May. Until about 8 weeks ago, I never even considered looking at anything Microsoft offered. Recently though, on a whim, I browsed over to the Microsoft site because I'd heard about their new release of Visual Studio. I'd been a Windows programmer back in the mid '90s and was curious to see how Visual Studio (it was Visual C++ back then) had evolved (or not). I didn't download Visual Studio but instead I downloaded a couple free tutorial videos for Microsoft's Web Developer Express product (which is a free product, BTW). Web Developer Express has a subset of the features in the full Visual Studio product and is used for building server-side (or client side, for that matter) web apps. I couldn't believe what I saw. Web Developer Express blows away anything we have in the Java world for developing server-side web apps. It was kind of a jaw-dropping experience to see what the tool can do and what ASP.NET offers compared to servlets/JSP/Struts/JSTL/JSF. I don't want to turn this post into a feature by feature comparison of ASP.NET and equivalent Java technologies. My impression, though, from watching these tutorial videos is that we in the J2EE world are living like knuckle-dragging Barbarians, scratching out an existence clothed in bear skins, using stone knives and sticks as our tools of choice. Those using .NET are living in fine brick homes with hardwood floors, fireplaces and regular visits from PeaPod. After looking at ASP.NET I became interested in looking at the C# language, proper. My impressions of C# vs. Java mirrored those of ASP.NET vs. servlets/JSP/etc. Java has kludgey support for properties and events (they're just regular methods with parameters) while C# has the constructs (delegates events) built directly into the core language. C# also supports co-routines, something we have to simulate in Java as well as out parameters (which allow a method to change the caller's parameter's value) and operator overloading. C# also has nullable types. Imagine Java's primitive types being able to hold null values. This is highly useful when working with databases. Finally, .NET provides an integrated and more comprehensive approach to setting security permissions and versioning of what are called, assemblies. Assemblies are very roughly equivalent to JARs. This allows you to compile your code against a specific version of an assembly and have that version information maintained in the resulting executable. It also allows several versions of the same assemblies (again, think JARs) to co-exist peacefully in a global, system-wide cache of assemblies. Sun should have given us something like this five years ago. Another advantage I saw with .NET is that it is more cross language friendly than Java. First of all, .NET, like Java, executes a platform neutral representation of a program (analogous to Java bytecode). Unlike Java, .NET programs can be written in many languages (C#, C++, Perl, Python, J#, VB, and many others). Microsoft's J# is, from what I've seen, a clone of Java (although I'm sure there are differences). The point I want to make is that once compiled, .NET programs can call each other seamlessly, regardless of the language the programs were originally written in. So for example, a J# class can extend a C# class which can extend a VB class. You're not tied to one language like you are in Java. I know that, theoretically, any language could potentially be compiled into Java bytecode (I guess Groovy is an example). Practically, however, this is not commonly done. Suffice it say, I am switching after 8+ years in Java. It was a tough decision at first because I have so much time and effort invested in Java. When I eventually get on a .NET project I will be starting over as a junior person making a junior person's salary. That won't be pleasant. I have close to $1,000 in Java books that I've accumulated over the years that are now for sale on Amazon. Ultimately though, I felt I'd be able to spend more time actually writing code on a single consistent, and what seems to be superior platform (.NET) rather than gluing together a half dozen open source tools with XML files, which it seems J2EE requires far too much of. To me, J2EE has become too fat and
Re: Are servlet name and class name required in web.xml for tomcat 5.5?
Please look into pre-compiling sources. You could look into - http://tomcat.apache.org/tomcat-5.5-doc/appdev/build.xml.txt and http://tomcat.apache.org/tomcat-5.5-doc/appdev/web.xml.txt When you pre-compile sources, it automatically generates a stub file that can be copied into web.xml.

Re: From Java to C#, ASP.NET [Off Topic]
You're right Tony, this posting is painfully off-topic for this list. Perhaps along with your new C# programming skills you can get work as an advertising writer for Microsoft. But, having said that, I would like to point out that Microsoft dumps a lot of money into researching and developing creature-features in their products, and developer hand-holding. Which is why you see the features you do. It's worthwhile to do a side-by-side features comparison and take advantage of Microsoft's investment into features development, and be aware of what features might attracts developers to a particular servlett platform like Tomcat. But, the bottom line with the Microsoft development tools, which I pay closely attention to myself, is that what you get in creature comforts you trade for in licensing fees and flexibility. That makes the perceived advantage you see is Microsoft products short lived - much shorter than the end-of-life cycle for Visual Studio. You might also consider that a skilled team with paper and pencil can develop and maintain Tomcat deployed applications that rival anything you can make with Visual Studio... and at less cost overall.

RE: How to find what encryption algorithm tomcat is using?
Thanks vineesh for your immediate reply. I'm using RSA while generationg a key. But I think it is for certificate keystore as given in the link http://tomcat.apache.org/tomcat-5.0-doc/ssl-howto.html. Does the same algorithm is used for data encryption also? If yes I think I can get complete details about algorithm in java site since just 'RSA' is not sufficient information.
