Re: Object sharing
Well, I think -Xnoclassgc is horrible. And singleton objects cannot be
shared among different application contexts, because they use
different classloaders.
Shared objects is better held in somewhere else, e.g., JNDI, although
I usually blame it =)
2006/5/22, Corobitsyn Roman [EMAIL PROTECTED]:
Hi
Sharing is possible with Tomcat
You must put your objects in shared classloader
For example:
public class ObjectPool {
private static ObjectPool objectPool = null;
private ObjectPool {
// initialize object
}
public synchronized static ObjectPool getInstance() {
if (objectPool == null) {
objectPool = new ObjectPool();
}
return objectPool;
}
}
And then put jar or compiled class into shared/lib or shared/classes
But prevent garbage collection, you must use the -Xnoclassgc start-up
parameter. (set JAVA_OPTS=-Xnoclassgc)
Other solution is adding the following member to a class that is always loaded
in an application:
private ObjectPool objectPool = ObjectPool.getInstance();
I hope this helps

BG By design I would use an EJB, this way you can also use
BG proper security to comtrol access to your bean. You can access the
BG EJB from any webapps, wether it runs or not on the same server.
BG And you can also expose it as a web service.
BG Using JBoss you will have tomcat out of the box as well as
BG transaction, security, etc And no license cost.

Re: Tomcat 5.5 / Apache 2 / Join (Tomcat-) Session with SSL-Session / Which mod should be used?
Hi! javax.net.ssl.SSLSession sslSession = (javax.net.ssl.SSLSession) request.getAttribute(javax.net.ssl.session); byte[] sslId = sslSession.getId() Will do the trick. Actually, no. This will just result in an NPE :). And, if you think about it, if Apache is handling the SSL traffic, then there would be no way to get this. What does work is: String sslid = (String)request.getAttribute(javax.servlet.request.ssl_session); This will give you the SSL Session-ID even if you are fronting with Apache (Apache passes it to Tomcat). However, be warned that this is a Tomcat-specific feature: It won't work if you try and port your app to another Servlet Container. Thanks for warning...

R: Help with Tomcat MySQL using JNDI
Sorry, it seems I sent a blank reply..
Anyway... I had the same problem with using JNDI with realm.. and finally I
wrote a context.xml which works fine..
/meta-inf/context.xml:
Context docBase=PMS path=/PMS reloadable=true
Resource name=jdbc/pmsRead auth=Container
type=javax.sql.DataSource username=user
password=userpwd
driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/pms maxActive=100
maxIdle=10 /
!-- Authentication realm --
Realm className=org.apache.catalina.realm.DataSourceRealm
localDataSource=true dataSourceName=jdbc/pmsRead
debug=99
roleNameCol=role userCredCol=password
userNameCol=username
userRoleTable=roles userTable=users /
/Context
The Resource jdbc/pmsRead works fine with the realm and within every class
of my web application if I access it using the following code;
try{
Context initCtx = new InitialContext();
Context envCtx = (Context)
initCtx.lookup(java:comp/env);
DataSource ds = (DataSource)
envCtx.lookup(jdbc/pmsRead);
Connection conn = ds.getConnection();
[query code here..]
}catch(Exception e){
[some code here...]
}
Hope it can help someway..

Problems with Realms and authorization
Hello! This is my first post to the list. My problem is this, I've configured Tomcat's file server.xml in order to use JDBC to authenticate users, and I've set up the realms and the different roles that can access to that realms, then, if i try to access to some realm but I haven't got the right role Tomcat redirect me to a error page (Forbidden Access) but it never ask again my user and my password. This occurs only if that user/password exists in my DataBase but it haven got the right role, If I enter a non exist user/password, Tomcat ask me again for them. How can I solve this? Could I change that error page that Tomcat shows? How? Thank you in advance... Alberto
Re: Problems with Realms and authorization
Hi Alberto. A user can be in two states in tomcat's point of view. 1) anonymous (that is the user has not yet provided user / password) 2) Authenticated (user has provided user / password) Aside from this, there are 2 kinds of urls for tomcat 1) unrestricted ones (anyone can access them) 2) urls restricted to specific roles (only authenticated users having the correct role can access them) As a result, when you try to access an url, those are the possible scenarios 1) public url - access is granted 2) restricted url and you are anonymous - you are pleased to log in 3) restricted url, you are authenticated but you don't have the correct role - access is refused 4) restricted url, you are authenticated and you have correct roles - access is granted Your problem is point 3, you used a user / pass that has not the priviledge for the given url. However, as you are authenticated, tomcat will not ask you to authenticate again. It already knows who you are and knows you can't acces that url. You should avoid design where an individual has to use different user / pass depending on what he want to do. It's better that he use only one account that got the requested priviledges. Really, there is a problem with J2EE specs you must care about. There is no way to log out, except by closing the browser. Changing the error page is of not help by the way. There is no way to force tomcat to accept a new user / password because there is no way to do it according to J2EE specs. Also, there is a difference between 401 Unauthorized 403 Forbidden 401 will request user / pass, 403 not. Forcing a 401 is useless because browser will cache user / pass and resend them without poping a new dialog. Regards Alberto Montoya wrote: Hello! This is my first post to the list.

My aim is to build dynamically (by the servlet) a transport with parameters received in request. Clear? By the way, i read : In general, applications should not need to use the classes in this package directly. Instead, they should use the APIs defined by javax.mail package (and subpackages).

Getting servlet context path without a servlet request.
I have a web application running under Tomcat 5.0, and I need to write some output to a file. This app doesn't have its servlet context hardcoded in anywhere, so I can deploy it with any name and not worry about missing some random bit of code anywhere, and I often deploy it with different names so the customers can compare 2 versions side by side. My problem is that I need to output to a log file within the application, and I'd like the logfile name to be the context name, so that I don't have to worry about 2 separate deployments inadvertently writing to the same file. I can get the context path from the first request that comes in, but until that point, I don't seem to be able to retrieve it from either the ServletContext or the ServletConfig... Am I missing something? I'm running in Tomcat, so I can hack it using some Tomcat-specific code, but I'd rather leave it as portable as possible. Anyone have any ideas?

RE: Class loading question
From: Black Buddha [mailto:[EMAIL PROTECTED] even after I've stopped the webapp Tomcat still holds an open file handle to the generated library files Welcome to a JVM bug. The essence is that: - File stream objects in the JVM hold onto the file handle. - The handle is closed only when the object is GCed. - On Windows, but not on Unix, an open file handle prevents file deletion. Your options are: - Run on UNIX, possibly in a virtual machine; - Ensure a garbage collection before the files need to be deleted - can be difficult, as System.GC() is only a hint (as I found out when I ran into this under somewhat different circumstances); - Don't use a JVM with this defect (but I don't know if you have any alternatives). - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Getting servlet context path without a servlet request.

Thanks, Tim. I'd just found a page on the 2.5 spec saying it was on its way. I think I'm going to just use ServletContext.getServletContextName() and just remember to keep them in step myself - I guess it's only an issue during development anyway, but it seemed like such an elegant solution.

filtering tomcat logging using default logging configuration
I have a web application which is using a library which is generating too many messages. These are routed to catalina.out and all come from a particular producer (org.jgroups. is the prefix). I do not want to rework the logging to use log4j or the like, but I would like to suppress these WARN messages for this prefix. I guess I need to modify $TOMCAT_HOME/conf/logging.properties, but what do I need to add? I have read the Tomcat 5.5 logging page, but I am none the wiser as that does not seem to give any examples of filtering non-Tomcat messages.

RE: Ant deploy task and cluster-wide (farm) deployment
Well, given that exec cp would be the same as my running it from the shell, and I've already observed that does not work (nor does it work from the explorer window(s)), I would guess that it won't work if forked-and-execed from ant. The question still remains - How do I know for sure that delete and copy are done and the app is undeployed / redeployed? With the deploy task, I know that the undeploy is complete when the http request completes. I was hoping there could be a similar mechanism in the works for the cluster model. I think it would be quite beneficial. I may have a few hours of spare time this week and if I do, I will attempt to characterize exactly what happens, how often, and when.

RE: Ant deploy task and cluster-wide (farm) deployment
I have done this for the QA cluster, since that gets done live. The production cluster gets done during maintenance windows. The point of using the farm deployer, or so I thought, was that I don't have to maintain the cluster members list in the build process.

Re: ClassCastException when forwarding wrapped HttpServletRequest
I remember seeing the spec that you can't do this, you have to provide a ServletRequestWrapper implementation Filip Yuri de Wit wrote: I am not sure I should have posted this question to the dev mailing list, let me know if that should be the case. I am using Tomcat 5.5.16. I have a series of chained HttpServlets in my web app. The first servlet is registered with the web.xml and the following ones are dispatched manually. Before delegating the HTTP request to the next internal servlet, I am wrapping the HttpServletRequest overriding getPathInfo() and getServletPath(). If the pathInfo was /a/b and servletPath was /x, after wrapping the request getPathInfo returns /b and the servletPath returns /x/a. The reason I am doing this is that I would like forward and includes to work relative to my internal pathInfo and servletPath (/b and /x/a) instead of the web container one (/a/b and /x). The first problem I encountered was that if I implemented the wrapper by subclassing HttpServletRequestWrapper Tomcat implementation unwraps it before forwarding and the final url contains the original path info appended and my custom path info. So I then changed my implementation and now I am wrapping the request using my own subclass of HttpServletRequest instead. Now the problem is that I get a ClassCast exception @ org.apache.catalina.core.ApplicationDispatcher line 814 (current = ((ServletRequestWrapper) current).getRequest();). Shouldnt that casting be conditional? Is there a safer way of implementing the functionlity I described above? thanks. - yuri - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Ant deploy task and cluster-wide (farm) deployment
I'm confused by the suggestion below -- the farm depoyer is entirely based on the appearance or disappearance of a .war file in the watch directory of the master tomcat node. No URL-based manager should come into play here, and using the standard manager (/manager/html) on such an application would likely result in conflicts or confusion. I was hoping to avoid having to visit some URL, or copy some file, for each member of the cluster. The whole point of the farm deployer, or so I thought, was to deploy, undeploy or redeploy from one and only one spot, and let the cluster (3 machines today, maybe 4 tomorrow and 10 in 2 years...) worry about getting the message out. My original question (request) was for a URL-based manager, like /manager/html, except which worked on the cluster. I.e., something like /farm-manager/html, which only appears on the master node, but functions identically to /manager/html from the outside, preserving the view that the cluster is a single entity. My experience suggests that the farm deployer is not 100% reliable (for me) at this time, perhaps it is the mixed OS, perhaps network lag -- not sure what. I have an existing, workable solution that works off of a list of tomcat servers (as a property), and uses the foreach... task (ant-contrib) to undeploy-then-deploy for each tomcat in the list. The danger in a production environment is that there are incompatible changes to objects on the session which would cause some strange failure during session failover. Those can be mitigated by upgrading during off-peak hours or planned maintenance, and/or limiting changes to session objects. (Just a historical note -- my company's business turns on making changes to various reporting screens on a weekly basis. So once a week we deploy a new war with all the approved changes for the week. We are at the mercy of state reporting requirement changes, and state mandated deadlines, so we don't have a lot of flexibility in when we do releases or updates. The nature of the business definitely exaggerates any warts, bumps or blemishes.)

Tomcat 4.1 - Problems referencing log4j.xml prop file within .war archive
Hello all,
I have attempted to research this problem on my own with little
progress. I am new to the dev scene so please keep this in mind if
responding. I have a log4j initialization servlet, and here is the
relevant snippet:
public void init() throws ServletException {
DOMConfigurator.configure(log4j.xml);
}
I am building the .war with ant and I don't believe Tomcat unrar's the
archive when it is running.
I need the log4j.xml properties file to be inside the war archive,
since there will be different config files for each webapp. I cannot
use getServletContext().getRealPath(/) since:
The real path returned will be in a form appropriate to the computer
and operating system on which the servlet container is running,
including the proper path separators. This method returns null if the
servlet container cannot translate the virtual path to a real path for
any reason (such as when the content is being made available from a
.war archive).
So my question is, how do I reference the log4.xml file for the
DOMConfigurator in these circumstances?
Tomcat 4.1.31
If more information is required to answer, please contact me and I
will respond momentarily.
thank you

Re: Classloader bug?
I remember long ago I had a similar problem, where it appeared that a jar of jars was working' as you basically describe, but for others running my code, it didn't work. The problem: I had overlooked the fact that during my runtime invocation, the jars were actually on the classpath via oversight. And in fact, the jars inside the jar file were not responsible for the success of the runtime instance at all. I'm not saying this is your problem, but it can happen. I know of no instances where a classloader will look inside a jar for other jar files. You can write a classloader to do this, but generally it cannot be assumed of an arbitrary classloader working on your behalf.

In fact I might become interested in those information. Average/max duration of time for each servlet/JSP. Is it possible to get those information? Yes :-) Since today. you can always write a script which is getting the data and graphing it... The problem is to collect the data :-) It seems to me that you are more interested in Loggers (classes which does generate log files) than their representation. I understand you, me, as developer should be also more interested in those. Ok, I see, you are more interested in who's calling what on my server and less in what the f*ck is my server doing. In fact, I've just started my server and Awstats shows me who is calling what on my server. It could take less memory, I don't like because it use CGI (potential security issues?) but it works :), and it is usable. At some point I might be more interested in what the f*ck is my server doing. (for example : the response is slow). Off course I might write my own loggers and trace duration time, but it might be good idea to ask: Is there any generic tool to use to find out what the f*ck is my server doing? Glad you asked :-) In fact I've built some of such monitoring systems over the years. I was always surprised, that there is no default monitoring toolkit in the java world. I don't mean logging, logging is simple. But to log something, you first have to produce the data, and besides JVM Monitoring data from BEA's jrockit there isn't much out there for production systems. So I decided to write one. You may be the first to try it :-) I've put a little demo under: http://anotheria.net:8180/moskitodemo/ It's pretty simple, one monitored servlet, klick on the make a request link (as often as you wish of course). On each click it will sleep some time (emulating working) or throw an exception (emulating error condition). You can view the stats for 1,5,15 minutes, 1 hour, 1 day or since start of the server (or whatever interval the servlet designer configured). A note on the stats generation: The stats are interval stats. That means, that the 5 minute value isn't the value of the last 5 minutes, but the value of the last 5 minutes interval update. To illustrate this, following example: The server is started at 12:00. You are checking at 12:03 the 5 minute stats. What will you see? Nothing, since no 5 minute intervals are completed yet. If you'll check again at 12:07 you will see the stats gathered between 12:00 and 12:05. After 12:10 you will see the stats between 12:05 and 12:10. And so on. This is imho the only way to generate comparable stats. If your server is slow today, you want to compare a 5 minute value to the one from yesterday, not a 3 minute value to 5 minute value and such. However, enough said. Try it out, tell me what you think :-) regards Leon P.S. Moskito is open source. I'm creating a downloadable distribution right now, which will contain the core system, logging add-on for log4j. Addon for servlet support. DemoApps and demo webapp (the one you see).

Don't mean to continue the hijack, however if I might add that it would be very helpful to just put a little note at the bottom (in the footer of the emails that's appended by the listserver) a one liner, like: To start a NEW topic, use: users@tomcat.apache.org This gives the user a one-click way to start a new message to the right email address.
