Re: Authentication crisis
the real problem is that we can't do anything before or after authentication
using a filter solve this problem with url pattern j_securty_check
but this is avoided because this authentication method must be equal basic
authentication?
this makes real authentication scenarios where we need create user session
with application data an autentic hell, adventages with container-based
applications turn back 0 and we need implements a custom authenticator, what
i see: i real subproject because security concerns is very important
ok, this is code of application, but the tomcat architecture avoid us (the
application programmers use the api of authentication in order to use these
type of methods) because of these jar are in server/lib folder
how you can see I'm very frustrated with this,
ok this is J2EE?
this is simple?

non US-ASCII query parameters
Hello i experienced a problem using tomcat-5.5.7 It does not understand non us-ascii query parameter. It seems it does decode all %XX as an index in US-ASCII table. How can i change it?

FW: Connector problem
Greetings all,
We have the following AJP connector configuration:
!-- A AJP 1.3 Connector on port 8009 --
Connector port=8009 address=${jboss.bind.address}
enableLookups=false redirectPort=8443 debug=6
protocol=AJP/1.3 scheme=https isSecure=true/
I expected that when my application does a request.getScheme() I will get back
HTTPS but I am not, I get HTTP. Do I not understand the purpose of scheme=?
The problem we are trying to solve is this:
1. Loadbalancer receives HTTPS request, terminates SSL and forwards HTTP
request to IIS server
2. IIS Server, using ISAPI Redirector, forwards request to JBoss/AJP Connector
3. When a Struts action is configured as a redirect the url returned to the
browser is HTTP not HTTPS.
Any help solving this would be greatly appreciated.
Earnie!

Some app server marketeers would have you believe that J2EE == EJB and Sun has not been too vocal about correcting this. The fact is that EJBs are just the most complex piece of J2EE. App server vendors love to get you all wrapped up in them because unlike most everything else in J2EE you need a full blown app server to do them, so you have to choose one of them once you place EJBs in your solution. Given that they're the most complex, they're also a piece that some, if not many, folk truly don't need -- and a piece that has taken until J2EE 5 to get right (e.g. usable) in the spec (assuming it is finally right there). -- Jess Holle - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I have to wait for several minutes between shutdown and startup for Tomcat to be able to startup correctly. If I run Tomcat without the APR connector, I don't have this issue. This does not occur on Windows, but does on Solaris and AIX. Has anyone else seen this? One thing I noticed is that the first thing logged on shutdown is an AjpAprProtocol pause entry, but there is no shutdown, stop or destroy. Is there any chance the APR connector is just getting paused and nothing is actually stopping it? Any help would be greatly appreciated. Thanks in advance. I suppose you have: Listener className=org.apache.catalina.core.AprLifecycleListener / in your server.xml But of course it doesn't guarantee it will be executed in all cases, if the JVM crashes for example. On Solaris it can take up to 4 minutes until the OS recycles the zombie socket. You can use: ndd -set /dev/tcp tcp_time_wait_interval 6 To lower that value. APR does not try to fool the OS like JVM, but rather behaves like Apache httpd.

As the leading full-stack Java/J2EE application framework, Spring delivers significant benefits for many projects, reducing development effort and costs while improving test coverage and quality. Some app server marketeers would have you believe that J2EE == EJB and Sun has not been too vocal about correcting this. The fact is that EJBs are just the most complex piece of J2EE. App server vendors love to get you all wrapped up in them because unlike most everything else in J2EE you need a full blown app server to do them, so you have to choose one of them once you place EJBs in your solution. Given that they're the most complex, they're also a piece that some, if not many, folk truly don't need -- and a piece that has taken until J2EE 5 to get right (e.g. usable) in the spec (assuming it is finally right there). This will be changed very soon with Ejb3 and the Ejb3 container can be embedded. With a careful planning, we can develop with POJO, and then add annotations for using Ejb3 persistence framework. To make this distinction, some vendors start to use JEE (instead of J2EE) to stand for your selected embedded libraries. Now we can mix and match different services from different vendors. I see this is the real strength of Java thanks to standards and open sources.

Need tomcat build for Fedora 3 on x86
Hi Tomcat List Subscribers, I need to install a recent Tomcat on a Fedora 3 Linux server as a Heartbeat application. I didn't manage the vanilla Tomcat installation (should you be interested to know why read below) Therefore I would like to ask you the Tomcat Gurus, how to do a Tomcat build and installation from the Java sources (into x86 bytecode?). When I run Ant on the provided build.xml Makefile from the tarball like mentioned in the quick install summary for Tomcat on another building host that can access the SV repository via an HTTP proxy I get the following: # ant Buildfile: build.xml check.source: get.source: build: proxyflags: download: [copy] Copying 1 file to /usr/local/src/apache-tomcat-5.5.15-src [copy] Copying 1 file to /usr/share/java setproxy: testexist: [echo] Testing for /usr/share/java/commons-beanutils-1.7.0/commons-beanutils.jar downloadgz: [get] Getting: http://archive.apache.org/dist/jakarta/commons/beanutils/binaries /commons-beanuti ls-1.7.0.tar.gz [get] Error getting http://archive.apache.org/dist/jakarta/commons/beanutils/binaries /commons-be anutils-1.7.0.tar.gz to /usr/share/java/file.tar.gz BUILD FAILED /usr/local/src/apache-tomcat-5.5.15-src/build.xml:48: The following error occurred while executing this line: /usr/local/src/apache-tomcat-5.5.15-src/build/build.xml:1834: The following error occurred while executing this line: /usr/local/src/apache-tomcat-5.5.15-src/build/build.xml:1962: java.net.ConnectException: Connection timed out Total time: 3 minutes 9 seconds What I don't understand is why I need to check out the Tomcat sources from a Subversion repository at all where I already have downloaded the whole tarball?

Could I surround say the checkout target block in the build.xml by !-- ... -- comment markers just to skip this step? How can Ant be invoked for certain install targets?

Pretty convoluted device stacking, isn't it? But we need to make the apps ha with synced filesystem (ext3) accross a dedicated private DRBD lan. Since a webserver usually only produces logfiles (no WebDAV) this seems like overkill, but for customer access_logs are vital. Heartbeat together with DRBD works perfectly for the webserver so far. This of course has nothing to do with Tomcat but what makes things pretty nasty is that the cluster is in a DMZ. That's why we did only a minimalistic installation, naturally dismissing all fancy GUI or X and other redundant stuff. Life could have been that simple if the customer hadn't out of the blue insisted on a Tomcat installation. Did I mention that I loathe GUIs? (and consequently most of Java stuff, why is no one writing Java apps that are content with a CLI alone?) First I tried installing Tomcat from the distributed Fedora 3 RPMs and was hit by a thousands of unfulfilled dependencies. Then I downloaded a JDK from SUN, as well as Ant and what I thought to be the Tomcat sources from tomcat.apache.org (or was it Jarkata? Those Java Folks come up with something new every week it seems) When I tried to run the self-extracting-installing JDK bundle it moaned that it couldn't start a GUI. It said that it had a special -console switch for subborn GUI-agnostic morons like me, but when I applied it it pretended to not know this option. (needles to sai that --console or -c or -C didn't help either) Ah, yes there was another -silent option that at least produced no further error messages but besides nothing else useful at all. The firewall to the intranet drops any X highports. Tunnelling via SSH (-X) also doesn't work since it's a oneway into the DMZ. Ok, next I tried installing that damned X to please the installer which nearly drove me insane. The RedHat Fedora package management

You support my point. Hibernate is a JDBC-based, JTA-aware, object-relational-mapping framework for Java. I say JTA-aware because you are not required to use JTA for transactions just because you use Hibernate (you can, but you are not required to.) It is perfectly valid and reasonable to write a Java application (desktop) which uses Hibernate, and/or JDBC, without touching any J2EE APIs.

Using JRE 1.5.0_06 causes app to use Tomcat tmp dir?
Hi. I've got a Tomcat 5.5.9 app which takes uploaded files and puts them into a directory according to this formula: app's root dir + /photos. So the dir in my case is c:\tomcat\webapps\ROOT\photos\. However, I've just noticed that the whole ROOT context directory gets copied to Tomcat's temp dir and the code is run from there. So calling getServletContext().getRealPath(/) in a servlet results in this: c:\tomcat\temp\0-ROOT\. So when the files get uploaded, they get put into c:\tomcat\temp\0-ROOT\photos\ instead of c:\tomcat\webapps\ROOT\photos\. And because it's a temp dir, when I shut down Tomcat, it all gets deleted(except for the WEB-INF dir), so I lose the uploaded content! Even more strange is that it seems to be random whether Tomcat clears the temp dir when I stop Tomcat. I know this didn't happen before, and they only thing that changed was the JRE version I've been using. So I'm wondering if anyone else has seen this behavior and can explain if it is JRE version related. Right now, the only work-around I've got is to replace the formula that builds the upload dir using something like 'get System.getenv(CATALINA_HOME)+/ROOT/photos', but I'd rather not have to do that. Thanks in advance for any pointers. -B - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It just so happens it provides a EJB-free solution to a servlet container environment. Hibernate does not require J2EE. I think hibernate supports JTA and JDBC? Ok, JDBC isn't J2EE since 3.0 but was before. (Actually it should become J2EE in 4.0, but this was changed). But JTA is J2EE as well as JMX, isn't it? Tim Leon. But actually it doesn't play a role..., just another crutch to keep relational databases in business :-) Actually JDBC isn't J2EE at all. XA transaction stuff is J2EE. XA can apply to a database or other transaction types as well completely unrelated to a database. JDBC is a standard J2SE API. See: http://java.sun.com/j2se/1.5.0/docs/api/ JDBC has been in the standard edition since 1.0 or 1.1. Everything in the docs here are standard java as of 1.5. See the 1.4.2 docs for pre 5.0 and obviously other versions to get pre version information for the version you look at. Thus, everything in this set of documentation is standard or J2SE and is not J2EE. For the list of APIs which is only J2EE (thoughmany if not most or all are available as separate API libraries from either Sun, Apache, or some other offering) see (this is 1.4): http://java.sun.com/j2ee/1.4/docs/api/index.html For a list of J2EE standards/specifications and future ones see: http://www.jcp.org and sort by technologies. and see: http://java.sun.com/j2ee/1.4/docs/index.html#specs Just want everyone to be clear what APIs are really J2EE and which ones are not before we discuss it. It seems to much misinformation gets out accidentally. The best source is to read the JSRs at the JCP. Then see a company such as Sun which lists all of the specifications for an easier view of the list. Doing that you can also see some applications and implementations which use the specifications. You can certainly create more than a trivial application completely skipping J2EE altogetherit just helps with some types of applications. For instance, you can take an implementation of a certain specification such as web applications and servlets. Create a servlet based web application and merely touch an API and specification not the complete J2EE stack and really don't have to call it J2EE if you don't want. Refer to it as it's JSR or say Servlet Spec 2.2, 2.3, or 2.4...pick one). Take Tomcat web applications for instance. You can reuse the Tomcat APIs to create a web application linking to the servlet.jar available from a distribution without ever downloading J2EE and linking to it. I believe what we see more of is the marketing hype and FUD confuses the use cases for many people and recruiters and human resource departments at organizations make it even more confusing for some others by the fact they don't know what their organization needs and all they know is what is on paper and then they try to talk about things like they know what they are talking about. That doesn't change the fact that one can create their own version of an API to match a certain specification then use that for linking and building to deploy to another system which supports many APIs and specifications including the one you may have targeted. So, just to be clear. Not all the APIs and specifications of J2EE have to be used to have a compliant application nor does a developer have to install J2EE to create a J2EE compliant application, they merely have to link to a set of interfaces matching a subset of J2EE for any given requirement, and sometimes this means it's easier to just download J2EE and get it all.

RE: Tuning Tomcat , i need some advice
Database interaction is by far the major issue. In my application, a page with no db interaction runs in something like 80ms, while a page with DB interaction takes something like 350-400ms. There's no silver bullet to tuning tomcat applications, and most of the advice you'll get here won't make any difference (use this connector, instead of that). So, my advice is: 1) Using JDK 1.5. It can be up to 25% faster than 1.4 2) Use the server JVM 3) Allocate sufficient memory 4) Start tuning your application. Look at query execution times, and the number of DB Interactions per page.

RE: Tomcat upgrade: 3.3.1 -- 5.0.28, hang up after running 1 or 2 days
This is a update for this problem/solution. After removing Java 1.5 + Tomcat 5.0, reinstalling Java 1.3 + Tomcat 3.3.1 on last Monday, 1/23/2006, everything has been running fine by far.

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.

Re: Tuning Tomcat , i need some advice
I'd ditto George's advice. Unless your page generation code is really trivial, it will be the major determining factor of your performance -- not Tomcat. Thus the first steps are general JVM tuning and application code profiling and tuning. Only after you've selected the right JVM, the right basic options, fed it enough memory, and tuned your code is it generally time to turn to further Tomcat tuning. -- Jess Holle George Sexton wrote: Database interaction is by far the major issue.

RE: Tuning Tomcat , i need some advice
I'm not familiar with Derby, so I'm not going to be able to offer any advice. The biggest killer will just be the number of db interactions. If you can create a view, or a stored procedure so that you're only doing one db interaction per page, then you'll see a huge difference. For example, if you have some complex code that queries different tables, and does a lot of processing to determine results, then a stored procedure will save a lot of time and effort. Other than that, my advice would be to benchmark the different queries ( using something like Jmeter) and fix what seems the slowest.

George Sexton wrote: Database interaction is by far the major issue. In my application, a page with no db interaction runs in something like 80ms, while a page with DB interaction takes something like 350-400ms. There's no silver bullet to tuning tomcat applications, and most of the advice you'll get here won't make any difference (use this connector, instead of that). So, my advice is: Indeed some pages of my web application will cause more than 4-5 select statement over tables with more than 50,000 records. will a dual processor server handle this loads ? I used derby as database . 1) Using JDK 1.5. It can be up to 25% faster than 1.4 2) Use the server JVM 3) Allocate sufficient memory 4) Start tuning your application.

Solution: Using JRE 1.5.0_06 causes app to use Tomcat tmp dir?
For anyone who's experiencing this, here's what's happening: ContextConfig.java contains a method called antiLocking that tests to see if your context in server.xml has antiResourceLocking=true. If it does, it creates a new directory calculated by 'deploymentCount++ + - + docBase ' in the temp directory. That's why I was seeing subdirs in temp called 0-ROOT and 1-ROOT... It turns out I had set antiResourceLocking=true thinking it would help performance when it was previously set to false. If Tomcat wasn't an open source project, I wouldn't have figured this out by examining the source code and probably would have never figured it out.

On Windows it depends more on your app (i.e. lots of large static files will see the most). Haven't really seen many numbers for other O/Ss. About the only way to tell with your app is to try it and see ;-). 2-how tomcat use it ? what else change in installation when we select to use native library With the default config, Tomcat simply looks for the dll at startup, and if it finds it, then it uses it. If it doesn't, it falls back to the Java Connector. The rest of the install is identical, so later just deleting/renaming the dll will give you the same install as if you selected not to use it. 3-in tomcat start-up application under start up tab ,there is a DropDown box which asks about mode that tomcat will run there are two modes ,1-JVM , -JAVA is it true that when we select JVM it uses JRE to run tomcat When we use java it uses JDK to run tomcat ? Not the best names, I'll grant you ;-). When you select JVM, the service loads the JVM into the service process via JNI, and runs Tomcat there. When you select JAVA, it spawns a seperate process that runs java.exe. Not sure how well JAVA is supported; I haven't tried to use it in a very long time.

Re: Why does mod_jk write a file ./conf/ajp13.id
It's for use of shutting down Tomcat over the AJP port (doesn't really work, and is disabled by default). As of 5.5.16+, Tomcat won't write the file unless you explictly enable this option.

Re: Connector problem
The AJP/1.3 Connector uses the scheme that is sent from IIS/Httpd/SunOne.
The scheme and isSecure on the Connector ./ is ignored.
I suppose that it wouldn't be too hard to add a believeMe=true attribute
to the Connector tag to handle your case. If you feel strongly about it,
open a BZ enhancement request. Of course, if you include a patch, it will
likely get looked at sooner ;-). Otherwise, a simple and obvious hack to
o.a.c.connector.CoyoteAdapter.postParseRequest will give you a custom
version of Tomcat that does what you want.

Greetings all,
We have the following AJP connector configuration:
!-- A AJP 1.3 Connector on port 8009 --
Connector port=8009 address=${jboss.bind.address}
enableLookups=false redirectPort=8443 debug=6
protocol=AJP/1.3 scheme=https isSecure=true/
I expected that when my application does a request.getScheme() I will get
back HTTPS but I am not, I get HTTP. Do I not understand the purpose of
scheme=?
The problem we are trying to solve is this:
1. Loadbalancer receives HTTPS request, terminates SSL and forwards HTTP
request to IIS server
2. IIS Server, using ISAPI Redirector, forwards request to JBoss/AJP
Connector
3. When a Struts action is configured as a redirect the url returned to the
browser is HTTP not HTTPS.
Any help solving this would be greatly appreciated.

I suppose you have: Listener className=org.apache.catalina.core.AprLifecycleListener / in your server.xml But of course it doesn't guarantee it will be executed in all cases, if the JVM crashes for example. On Solaris it can take up to 4 minutes until the OS recycles the zombie socket. You can use: ndd -set /dev/tcp tcp_time_wait_interval 6 To lower that value.

logic:iterate id=p1 name=myForm property=list1
logic:iterate id=p2 name=myForm property=list2
logic:iterate id=p3 name=myForm property=list3
${p3}
/logic:iterate
/logic:iterate
/logic:iterate
p3 is not printed out.
Am I right?
Here is my real code, did I do something worong? The
most inside logic:iterate did not print.
logic:present name=protocolForm

logic:iterate indexId=idx id=media

Where do we put Business Logic(BL) and DBConnection files in Tomcat 5.5.15 in JSP?
hello, I'd made a JSP page and included a package in which my Bl(Business Logic) file is stored as :- %@ page import=primeReports/bl/MemGrossBl% This package is in ROOT directory in webapps. but whenever i'm executing the page, the error is coming as it could not be able to find this package and file. Similarly i'd made my seperate DBConnection file which is in ROOT\primeReports\db\ and the same problem is coming,as whenever i'm executing it the compiler is giving an error that package primeReports.db does not exist. Kindly tell me : Where do we put Business Logic(BL) and DBConnection files in Tomcat 5.5.15 in JSP? as we put classes12.jar in common/lib, is there any such requirement for BL and DBConnection files also?

RE: Download file Problem - 404 error
Hi Deepa, I had the a similar problem and ONE of the reason to get a NoCalssDefFoundError is that Tomcat is encountering more than one Servlet jar in the classpath(which are different versions). I suggest you remove all the entries for servlet jar from the classpth in environment variables and try accessing your application. ping me if you require more info.

RE: Download file Problem - 404 error
Deepa, As someone pointed out in an earlier post you need to include the following in your DownloadFile.java file: (usually, as the first line) package com.deepa.servlet; You would also normally place DownloadFiles.java in a directory that ended in com/deepa/servlet. In WinSpeak: D:\data\eclipse\workspace\com\deepa\servlet\DownloadFiles.java After a successful compile, com\deepa\servlet\DownloadFiles.class should be copied to the WEB-INF\classes directory of your web app. - Bob -Original Message- From: DEEPA M N [mailto:[EMAIL PROTECTED] Sent: Tue 1/31/2006 11:43 AM To: Tomcat Users List Cc: D:\Tomcat5.0\jakarta-tomcat-5.0.28\webapps\DownloadFile\WEB-INF\classesjava com.deepa.servlet.DownloadFiles Exception in thread main java.lang.NoClassDefFoundError: com/deepa/servlet/DownloadFiles (wrong name: DownloadFiles) __ Do You Yahoo!?
