Finalizing classes in common or shared directories
Hello, I have several contexts running in Tomcat(5.5.23), which use some common utilities. Classes for these utilities are in shared/ directory of the Catalina installation. Is there a way by which Tomcat can invoke a callback on these classes (shared/*) when it is shutting down? I need this to perform cleanups. Basically, I would use an equivalent of ServletContextListener.contextDestroyed() callback in deployed contexts. I failed to stumble upon any useful googled info. Thanks
Re: Custom URL handlers in Tomcat web app
Hi Matt, I am trying to port legacy JRun application to Tomcat facing same problem. I also tried out the listed options but without any luck. Do let me know if you are able to crack. Since I have legacy application, I do not want to introduce any new code to make it work. Thanks, Praveen M. MK-24 wrote: Hi everybody, I have the following problem: My Web application needs to handle Lotus Notes URLs which use the scheme notes. However, since Java does not know this protocol by default, it throws a MalformedUrlException when I construct a java.net.URL from a notes:// URL-string. So, I read up on custom URL handlers and as far as I understand, you have to code a custom URLStreamHandler class and a custom URLConnection class. Okay, no big deal. However, there are three ways to register your new handler: 1) put it in the sun.net.www.protocol.yourprotocol package 2) put it in a custom package and declare that package to the JRE using the java.protocol.handler.pkgs system property 3) register a custom URLStreamHandlerFactory using URL.setUrlStreamHandlerFactory problem is, none of these approaches work in Tomcat 5.5. For 1), this simply didn't have any effect for me. 2) neither, maybe Tomcat simply ignores that property? 3) doesn't work because Tomcat already registers its own factory, and for some reason I can't quite put my hands on you are not allowed to call that method twice per JVM instance. This issue is also discussed on Sun's Java issue tracker: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4648098 The ticket has been opened six years ago and still no fix! Does Tomcat meanwhile have some workaround for this? I mean, I don't even need an actual URL connection, I just want to pass custom URL strings, which should be perfectly fine if they are valid URLs, no?! I hope you can help!

The following error is outputted when the code is

nested exception is:

Now I have checked:
- the same java mail version is used across

- the same JRE (v1.6)

Tomcat 4.1.30 Compression Not Working
We have a Linux server running Tomcat 4.1.30, serving jsp pages. We have tried to enable gzip compression by the addition of the compression=on attribute to the server.xml file. We've seen some odd results. First of all we couldn't get any compression to take place (using Fiddler to monitor responses). We spent along time tweaking the settings, mainly the compressableMimeType list. Eventually we witnessed some compressed results, but a few moments later it wasn't working again with no changes from ourselves. This happened on more than one occasion. The interesting thing is that we have another test server on a Windows Server OS on which the compression works fine. JRE version is 1.4.2 if that's of any relevance.

Re: Database connections grow after redeploy
Memory leaks and deadlocks and CPU hogs! Java application developers often face these runtime problems. They can be particularly daunting in a complex application with multiple threads running through hundreds of thousands of lines of code -- an application you can't ship because it grows in memory, becomes inactive, or gobbles up more CPU cycles than it should. Here are some tools that can help you finding out your application performance. You can monitor thread usages, memory leaks, instance count etc; also in case of web application you can find out the number of sessions, number of request per second, average response time, database connection time, error count etc. 1 JProfiler: JProfiler is an award-winning all-in-one Java profiler. JProfiler's intuitive GUI helps you find performance bottlenecks, pin down memory leaks and resolve threading issues. You can use it to monitor a standalone java application or a web application. http://www.ej-technologies.com/products/jprofiler/overview.html Features: · Live profiling of a local session · Live profiling of a remote session · Offline profiling · Snapshot comparisons · Memory profiling · Heap walker · CPU profiling · Thread profiling 2.

Re: Database connections grow after redeploy
Memory leaks and deadlocks and CPU hogs! Java application developers often face these runtime problems. They can be particularly daunting in a complex application with multiple threads running through hundreds of thousands of lines of code -- an application you can't ship because it grows in memory, becomes inactive, or gobbles up more CPU cycles than it should. Here are some tools that can help you finding out your application performance. You can monitor thread usages, memory leaks, instance count etc; also in case of web application you can find out the number of sessions, number of request per second, average response time, database connection time, error count etc. 1 JProfiler: JProfiler is an award-winning all-in-one Java profiler. JProfiler's intuitive GUI helps you find performance bottlenecks, pin down memory leaks and resolve threading issues. You can use it to monitor a standalone java application or a web application. http://www.ej-technologies.com/products/jprofiler/overview.html Features: · Live profiling of a local session · Live profiling of a remote session · Offline profiling · Snapshot comparisons · Memory profiling · Heap walker · CPU profiling · Thread profiling 2. ManageEngine® Applications Manager 8 http://manageengine.adventnet.com/products/applications_manager/applications-monitoring-features.html Applications Manager provides in depth monitoring of web applications, be it a CRM application, banking / finance application or any business critical application. Applications Manager can also help monitor the underlying infrastructure which may consist of application servers, databases, systems, mail servers and other Java/J2EE Applications. Through the application monitoring feature you can ensure the health and availability of your application servers through Microsoft .NET Monitoring, Oracle Application Server Monitoring, JBoss Monitoring, Tomcat Monitoring, WebLogic Monitoring, and WebSphere Monitoring. Out-of-the-box support for databases through Oracle Monitoring, SQL Server Monitoring, MySQL Monitoring, DB2 Monitoring is also present. Applications Manager helps ensure higher uptime by detecting and diagnosing problems of application servers and their services faster 3. JMeter http://jakarta.apache.org/jmeter/ Apache JMeter is a 100% pure Java desktop application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions. Apache JMeter may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. You can use it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load Apache JMeter features include: · Can load and performance test HTTP and FTP servers as well as arbitrary database queries (via JDBC) · Complete portability and 100% Java purity . · Full Swing and lightweight component support (precompiled JAR uses packages javax.swing.* ). · Full multithreading framework allows concurrent sampling by many threads and simultaneous sampling of different functions by seperate thread groups. · Careful GUI design allows faster operation and more precise timings. · Caching and offline analysis/replaying of test results. · Highly Extensible: oPluggable Samplers allow unlimited testing capabilities. oSeveral load statistics may be choosen with pluggable timers . oData analysis and visualization plugins allow great extendibility as well as personalization. oFunctions can be used to provide dynamic input to a test or provide data manipulation. oScriptable Samplers (BeanShell is fully supported; and there is a sampler which supports BSF-compatible languages) 4 Lambda Probe (formerly known as Tomcat Probe) http://www.lambdaprobe.org/d/index.htm Lambda Probe (formerly Tomcat Probe) is a self sufficient web application, which helps to visualize various parameters of Apache Tomcat instance in real time.

latest mod_jk version compatible with Apache 1.3.26
Hi, when running Apache 1.3.26 (from Debian Woody), what is the latest mod_jk version compatible to that apache version? On http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.26/i386/ for example is written: mod_jk-1.2.26-httpd-1.3.39-eapi.so is for Apache 1.3.x with EAPI extensions and works with Apache 1.3.39 and later. So it seems that mod_jk-1.2.26 does not work with Apache 1.3.26 ? And no, unfortunateley I am not allowed to update the Apache itself... Thanks Stephanie -- Psst!

Re: Tomcat and parallel security realms
Christopher,
the idea you sketched depends on the constructor being called with a
list of realms. Is that so?
If you look at http://tomcat.apache.org/tomcat-6.0-doc/api/index.html
all realms in org.apache.catalina.realm have only the default constructor.
Probably one would have to get the surrounding container with
Realm.getContainer() and browse the whole nested container tree to get
all realms.
So, a delegating realm seems not that easy. Anyway, I think the
feature of using several realms should be in the server core.

Right.

Write a Realm that wraps two other realms, and use that. Something like
this:

{

~_realms = realms;

~// implement the other methods similarly as pass-through methods

I would tend to agree.
If you were to write a decent implementation of the above, I would
imagine that the Tomcat folks would happily accept it as a contribution
to the project.

See `config.log' for more details.
I downloaded commons-daemon-1.0.1 (the most recent although 3 years old)
and it runs configure without problems. I compared the line numbers from
your output and they don't coincide with mine. So either you are using a
strange jsvc version, or you regenerated the configure script. Check if
your configure script still has an old time stamp (mine is May 17, 2005)
and is located in daemon-1.0.1/src/native/unix.

Rainer

Need to upgrade to Tomcat 5.5.26 in JBoss 4.0.5
Greetings; We're using JBoss 4.0.5.GA, bundled with Tomcat 5.5.20. Security vulnerabilities were found in Tomcat 5.5 and Tomcat 6.0 and fixed in Tomcat 5.5.26 and 6.0.16, and users are advised to upgrade. The design of Tomcat folders/files in JBoss 4.0.5.GA doesn't match the full (or embedded) Tomcat 5.5.26 installation, so I don't know how to upgrade Tomcat without upgrading JBoss. I looked at JBoss upgrades, but no stable release is available that includes the required Tomcat version. I asked JBoss Support how to upgrade Tomcat without upgrading JBoss, but didn't get a response. Can Tomcat be upgraded separately from JBoss, or is the upgrade something that JBoss must provide? Can someone point me in the right direction on how to upgrade from Tomcat 5.5.20 to 5.5.26 within JBoss 4.0.5? Thanks, Steve
Re: Trouble building jsvc
Thanks for the reply. which version of jsvc do you try to compile? The one distributed with Tomcat 6.0.16. It's in tomcat/bin as jsvc.tar.gz. Which docs page are you referring to? I mean the main Tomcat site... http://tomcat.apache.org/tomcat-5.5-doc/setup.html I also checked the file INSTALL.txt that's inside jsvc.tar.gz. I tried generating the configure script using autoconf. And also I tried what it said in INSTALL.txt: sh support/buildconf.sh Same result each time -- what I described.

I had not heard of commons-daemon before. I was going by the docs on the Tomcat site. Is it better to use commons daemon?

DelegatingCallableStatement.getInnermostDelegate() -- NoSuchMethodError
I'm getting a NoSuchMethodError on
org.apache.commons.dbcp.DelegatingCallableStatement.getInnermostDelegate
().
AFAICT DelegatingCallableStatement inherits ultimately from
DelegatingStatement, which DOES have such a method. I've examined the
commons-dbcp-1.2.1.jar file that's in the classpath, and the
inheritance hierarchy looks OK and there IS a getInnermostDelegate()
method on DelegatingStatement.
Since this is running in BusinessObjects' Tomcat 5.0 server I thought
there might be a classloader problem. I printed out the classloaders
at the point where the error happens, but the debugging output seems
to indicate that everything should work -- but I still get the
exception. I can't really post an SSCCE as this is buried in a much
larger system that runs only under Tomcat.

I would check to make sure you have (at least version( 1.21 DBCP

RE: DelegatingCallableStatement.getInnermostDelegate() -- NoSuchMethodError
From: Jim Garrison [mailto:[EMAIL PROTECTED] Subject: DelegatingCallableStatement.getInnermostDelegate() -- NoSuchMethodError I've examined the commons-dbcp-1.2.1.jar file that's in the classpath What do you mean by classpath? The CLASSPATH environment variable must NEVER be set for Tomcat (nor should it be used for any other Java application, these days), and the command line -cp argument should not contain any additional jars beyond those set by the Tomcat startup scripts. Any jars needed by specific webapps should be in that webapp's WEB-INF/lib directory (or possibly in shared/lib, if absolutely necessary). Note that Tomcat includes its own renamed version of commons-dbcp to support container-managed DB connection pools; why aren't you using Tomcat's built-in facility, rather than rolling your own? this is running in BusinessObjects' Tomcat 5.0 server Also note that Tomcat 5.0 is no longer actively supported, having been supplanted by 5.5 and 6.0. Since this is a repackaged, unsupported version of Tomcat, you should discuss the problem with the Business Objects support group. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
