Re: DataSource and initialContext.lookup(java:comp/env)
java:comp/env is the default namespace defined by JNDI. The call to lookup() with this as an argument is returning an instance of a context corresponding to that namespace, which you need to do a further lookup for your specific resource. On a related note, I'm pretty sure you could condense all the code you have to just one line, something like: DataSource ds = (DateSource)new InitialContext().lookup(java:comp/env/jdbc/wms) I'm fairly certain that works. That might be clearer to you. -- Frank W. Zammetti Founder and Chief Software Architect Omnytex Technologies http://www.omnytex.com Eric Wulff wrote: helpful somewhat... at least in helping me narrow my question.

That gives you a starting context. Then if you want to retrieve a particular file in that domain, you look it up relative to the domain (i.e., www.apache.org/tomcat.htm). Same thing here... There is a hierarchy of JNDI resources, a tree structure, that has an initial context as the root. You then are in a sense constructing a path to your DataSource, and it might look something like /initial_context/java:comp/env/jdbc/wms (not exactly, but you get the idea).

Accessing resource in WEB-INF outside servlet
Hi. I have a file in WEB-INF which I want to access. However, this is done in a static class which is not a servlet, so I do not have the servlet context. Is there a way to access the servlet context non the less? Is there a way to make getResource find the file anyway? I know a resource is found when it's in /WEB-INF/classes, but it is only in /WEB-INF/ and it is not an option to move it to the classes directory. Can you help me?

Re[2]: DataSource and initialContext.lookup(java:comp/env)
It's also helpful, I think, to look at a JNDI directory as a database that's organized in a directory-like fashion. The database contains objects, not arbitrary data, however. The context is effectively the database name, and when you lookup something in the context, you're effectively looking it up in that database. Don't confuse any of this with the file-system directory out on your hard disk. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: yoav, can u suggest something?
Hi Vaneet, Rather than reiterate Yoav's comments I will simply suggest that you learn a little about HTML and HTTP or even better RTFM. Your site is operating within a frameset thus the URL in the browser stays the same whilst the underlying URL for each page changes within a frame. When someone refreshes the browser re-requests the the URL displayed in the Address Bar, thus your homepage reappears. It is correct and expected behaviour.

FW: Configuring JAAS realm for a web appplication (Catalina class loader bug)
Title: FW: Configuring JAAS realm for a web appplication (Catalina classloader bug) Hi, My company isusing Tomcat 4.1.29 and I'm investigating a transition to version 5.0.28. We use JAAS for authentication. The realm is decleared inside the web application context. The authentication code makes an EJB call to jBoss server (we are using stand alone Tomcat not jBoss bundled version). In verion 4.1 we have ejb-client code jar in both server/lib and Web Application lib directories. I have replicated the same structure in version 5 but I get ClassCastException inside my JAAS Authentication module. If I remove the copy of ejb-client jar from Web Application it all works fine which suggest to me that the ClassCastException related to the fact that the same class id loaded by different classloaders. Tomcat doco specifies that Catalina classloader is invisible to webapplications ( and that's why we use it in Tomcat 4) but it doesn't seem to be the case. The work-around (removing ejb-client code from web app) is not a solution because it has a lot of web app specific code. If I don't copy authentication code to server/lib directory and only keep it in web app Tomcat doesn't find it. That is the case for both versions - 4 and 5. To me it suggests a different problem - since JAAS realm declared in web app context it should apply to web application only and therefore it should be looking into webapp not server/lib directory. But that is a different discussion topic altogether.

The LDAP directory structure is somewhat like this -

When I try to access the link, http://localhost:8089/param_test, it
prompts me for the username and password. When I type in these

Re: FW: Configuring JAAS realm for a web appplication (Catalina class loader bug)
Well, the short answer is, move it to common/lib, not server/lib. server/lib is for stuff that *only* Tomcat itself should see. common/lib is for stuff that both the server and applications should see (and shared/lib is the converse of server/lib, but different from WEB-INF/lib since it is global to all apps in the server). Even in the common/lib case, you may run into the same problem, though, because if you put the jar in WEB-INF/lib, that will be loaded, preferentially by the application because of child first classloading behavior that Tomcat implements. If JASS looks up this class as well, but loads it in a different classloader you will run into the same issue. In this case, you'll need to remove the jar from WEB-INF/lib and load it from common/lib only. I can't say for sure that it isn't bad behavior by Tomcat, but I doubt it. It is just a classloading issue you'll have to deal with. However, this is one reason why many appservers out there don't use child first classloading behavior by default, although in the server/lib situation you'd get the same result in this case. The common/lib case would have been taken care of in a server implementing normal parent first classloading behavior, but then it would be redundant to have the jar in WEB-INF/lib in that case anyway. Bottom line is that classloaders are tricky and different situations call for different solutions so I doubt there is anything fundamentally wrong with what Tomcat is doing.

As a matter of fact I have started with that option. However it produces the same result. I have tried to move ejb-client jar out of of web app. But then I run into the problem when the application uses a class loaded by common class loader and if the class references another class in the WEB_INF/lib jar (a different jar) I get NoClassDefError. Effectively the only safe way to install my application in that scenario is to copy all application jars into common/lib and that is fundamently wrong. What I don't understand is why my set up works in 4.1.29 and doesn't work in 5.0.28. -Original Message- From: Jacob Kjome [mailto:[EMAIL PROTECTED]] Sent: Monday, 8 November 2004 3:52 PM To: Tomcat Users List Subject: Re: FW: Configuring JAAS realm for a web appplication (Catalina class loader bug) Well, the short answer is, move it to common/lib, not server/lib. server/lib is for stuff that *only* Tomcat itself should see. common/lib is for stuff that both the server and applications should see (and shared/lib is the converse of server/lib, but different from WEB-INF/lib since it is global to all apps in the server). Even in the common/lib case, you may run into the same problem, though, because if you put the jar in WEB-INF/lib, that will be loaded, preferentially by the application because of child first classloading behavior that Tomcat implements. If JASS looks up this class as well, but loads it in a different classloader you will run into the same issue. In this case, you'll need to remove the jar from WEB-INF/lib and load it from common/lib only. I can't say for sure that it isn't bad behavior by Tomcat, but I doubt it. It is just a classloading issue you'll have to deal with. However, this is one reason why many appservers out there don't use child first classloading behavior by default, although in the server/lib situation you'd get the same result in this case. The common/lib case would have been taken care of in a server implementing normal parent first classloading behavior, but then it would be redundant to have the jar in WEB-INF/lib in that case anyway. Bottom line is that classloaders are tricky and different situations call for different solutions so I doubt there is anything fundamentally wrong with what Tomcat is doing.

The realm is decleared inside the web application context. The authentication code makes an EJB call to jBoss server (we are using stand alone Tomcat not jBoss bundled version). In verion 4.1 we have ejb-client code jar in both server/lib and Web Application lib directories. I have replicated the same structure in version 5 but I get ClassCastException inside my JAAS Authentication module. If I remove the copy of ejb-client jar from Web Application it all works fine which suggest to me that the ClassCastException related to the fact that the same class id loaded by different classloaders. Tomcat doco specifies that Catalina classloader is invisible to webapplications ( and that's why we use it in Tomcat 4) but it doesn't seem to be the case. The work-around (removing ejb-client code from web app) is not a solution because it has a lot of web app specific code. If I don't copy authentication code to server/lib directory and only keep it in web app Tomcat doesn't find it. That is the case for both versions - 4 and 5. To me it suggests a different problem - since JAAS realm declared in web app context it should apply to web application only and therefore it should be looking into webapp not server/lib directory. But that is a different discussion topic altogether.

Re: Environment entries question
Hello! I have made some researches and I think, that I have found patch, that solves my problem. I tested it a little. It works fine for me. But I might miss something important while testing. As I mentioned in previous letter, open Bugzilla item is related with my problem, but it is not the same. It is JNDI env-entry not reload when context reloaded (http://issues.apache.org/bugzilla/show_bug.cgi?id=29727) My patch will solve the following problem If Environment entry is changed using admin app, the change is not visisble in JNDI. So I am attaching my patch to the letter.

Re: Doubts with tomcat
1) When I start tomcat with above server.xml , it creates 9 process with same output on shell. it is I configured tomcat to run with minSpareThreads=5 then why it start with 9 threads? You configured 5 connector threads that not necessarily match OS threads (or whatever you saw). Check with Tomcat's manager application how many connector threads you really have. 2) In tomcat , port 8080 is redirected to SSL port 8443. Why NON-SSL port is redited to SSL port? That's used, if one of your webapps has a security constraint (can be done in the web.xml) saying that this app (or some of its resources) may only be accessed using https. In that case, if Tomcat receives a http request it will automatically redirect the browser to the same resource, but using https scheme and using the mentioned redirect ports. Thus you won't have to do ugly port number hardcoding into your app (or other strange approaches), if you need to support https. Please help me to understand these basics. Hope I could help.

Starting Tomcat as an Apache inprocess with Jni
Hi, I have problems starting the Tomcat as an inprocess of Apache via Jni. I tried that with the examples of the Jakarta Hompage. Running Apache and Tomcat seperatly and connect both with a Socket-Connection is no problem and works fine. That tells me that the mod_jk2 is well working. My System : Windows XP SP1 Apache 2.0.52 (Folder: C:\Programme\Apache Group\Apache2) Tomcat 5.0.28 (Folder: C:\Programme\Apache Group\Tomcat5) Java SDK 1.5 (Folder: C:\Programme\Java\jdk1.5.0) Error file of Apache (Folder: C:\Programme\Apache Group\Apache2\logs): [Thu Nov 04 08:08:52 2004] [notice] Parent: Created child process 4628 [Thu Nov 04 08:08:52 2004] [notice] Child 4628: Child process is running [Thu Nov 04 08:08:52 2004] [error] workerEnv.initChannel() init failed for channel.jni:jni [Thu Nov 04 08:08:52 2004] [error] workerEnv.initWorkers() init failed for worker.jni:onStartup [Thu Nov 04 08:08:52 2004] [error] workerEnv.initWorkers() init failed for worker.jni:onShutdown [Thu Nov 04 08:08:52 2004] [notice] Child 4628: Acquired the start mutex. [Thu Nov 04 08:08:52 2004] [notice] Child 4628: Starting 250 worker threads. it seems that the Apache can't find the starter class for the Tomcat. What have I done wrong? As I know, running Tomcat as an inprocess of Apache on the same PC is the fastest connection between both servers. Because of that i tried that very hard getting this constellation running. best regards Oliver
