Re: Out of Memory error - Tomcat 3.2.1
Somik, Are there really more than 1000 threads? When I start tomcat I get about 35 threads... are you running a standardish configuration or have you changed things? When you say you've checked your servlets and none of them have threads that dont end - are you sure? maybe post one of your servlets so people can check it. cheesr dim On Tue, 31 Jul 2001, Somik Raha wrote: > Hi, > Sorry for posting earlier in Rich Text. > > I am using Tomcat 3.2.1 with Apache. > I find a strange phenomenon - whenever an http request is made, a > tomcat thread is created.

How to make a database connection in a servlet ?
Hi, I am running Apache 1.3.20, Tomcat 3.2.3 and JDK 1.3.1 from Sun on Windows NT and everything is working fine. Because these are my first experiences with a web server, I had a look at several samples delivered with Tomcat. But how will I be able to connect from a sevlet to an Oracle 8.1.6 database server (not running on the local machine) ? Do I have to use the RequestInterceptor JDBCRealm declared in the serverl.xlm file ? On the machine running the Apache and Tomcat I have an Oracle client 8.1.7 installed. Can anyone explain to me the steps I have to follow, and explain how they work ? (a few lines of sample code would be very nice) Thanks in advance and regards Andreas
Out of Memory error - Tomcat 3.2.1
Hi, Sorry for posting earlier in Rich Text. I am using Tomcat 3.2.1 with Apache. I find a strange phenomenon - whenever an http request is made, a tomcat thread is created. But when the servlet finishes, the thread is not destroyed. This results in a big problem - after sometime, an OutOfMemory exception is thrown - with the message "Unable to create Native Thread". Doing "pstree -ap" shows more than a thousand threads under the tomcat process (there are only a few servlets). I have checked my servlets, none of them have threads that dont end. I checked the Tomcat page, and it says I ought to upgrade to 3.2.3, as there are a lot of performance fixes. Is this one of them ? I want to make sure this is the problem, or the problem lies elsewhere.. Will appreciate help on this issue. Thanks. Regards, Somik

error affecting all sessions
Whenever I get a certain error using one account, other accounts/sessions are also affected and I may need to restart the tomcat server. And sometimes when I do a restart, I still need to check if java threads still exist before starting it again.

Currently, mod_webapp forwards _ALL_ requests to tomcat for a given web-application, but within its structure there's already a hook to parse the web.xml file and process it... At the end, I'll be happy to see static files served by Apache (whenever possible) and all the rest handled by Tomcat... It's not a big hack, and I am trying to have it working by the next release of the WebApp module... But, on the other hand, currently mod_webapp is the only one that is 100% compliant with the servlet spec... :( Pier
Out of Memory error - Tomcat 3.2.1
Hi, I am using Tomcat 3.2.1 with Apache. I find a strange phenomenon - whenever an http request is made, a tomcat thread is created. But when the servlet finishes, the thread is not destroyed. This results in a big problem - after sometime, an OutOfMemory exception is thrown - with the message "Unable to create Native Thread". Doing "pstree -ap" shows more than a thousand threads under the tomcat process (there are only a few servlets). I have checked my servlets, none of them have threads that dont end. I checked the Tomcat page, and it says I ought to upgrade to 3.2.3, as there are a lot of performance fixes. Is this one of them ? I want to make sure this is the problem, or the problem lies elsewhere.. Will appreciate help on this issue. Thanks.

That works until you try a servlet mapping in your web.xml file, or a security constraint, or a bunch of other things. Current generation connectors for Apache (but not mod_webapp under Tomcat 4) totally ignore the contents of the web.xml file, so you have to tediously configure everything twice. > You still > have to do all the configuration stuff in tomcat anyway.

I don't consider it that painful. It's hardly a pain at all. It involves adding an include to apache's httpd.conf. You still have to do all the configuration stuff in tomcat anyway. But I've heard from more than one that Tomcat is faster. So there's that. But if security is an issue for you I have a hard time believing that Tomcat is as secure as Apache.

I'm > assuming you're not running tomcat as root? Nope, I'm not... Currently there's a test project to run Tomcat 4.0 as a native daemon in Unix. You can check out and build the "service" code in the "jakarta-tomcat-4.0/service" CVS repo, and try it out. I'm building a new (more portable) API in "jakarta-tomcat-service", and that will be (probably) the default way to invoke Tomcat from the next beta. Both of them (the one in TC4 and the new Service) allow to run TC4 as an operating-system daemon, binding to port 80 and running as a non-root user... I don't know whether those will be adopted by TC3 also or not, but they _do_ work :) Pier

Re: Upgrade to Tomcat DECREASES Performance?
Good enough to have answered this question several times.

It allows you to stop and start TC without restarting Apache. You can download the 3.3 distribution and make it yourself, or just use the pre-compiled binary for Linux (which is what I use). It's compatible with 3.2.x and can be found here: http://jakarta.apache.org/builds/jakarta-tomcat/release/v3.3-b1/bin/linux/i3 86/ -- Upgrade to 3.2.3. It's really easy. You just copy the jar files into your existing installation. The release notes explain it. -- Monitor the tomcat-dev list.

RE: Setting JVM Memory configuration
Firstly, running out of memory after a predictable period of running (rather than because of peak loading) suggests a memory leak. These are possible in Java if you hold onto object references accidentally once you're done with them (or libraries you call do so). If this is the case, adding more JVM memory won't help you. You may want to monitor your Java memory usage with the JVM profiler (or an external tool like jProbe). Assuming that this isn't the case, then you have the correct command line parameter - you're setting it to about 120 Mb in your example (which you can specify as "-Xmx120M" if you prefer). The default value for this is 64 Mb on Solaris and WinNT with Sun's JVM.

Unless you don't specifically require some of the Apache functionalities, run it stand alone, might be slightly slower in some cases, but far more stable. Actual improvements can be achieved using JNI and a multi-threaded web-server such as Apache 2.0, but AFAIK, for Tomcat 4.0 we're still far from that... :( Ok, I'm working on it :) :) Pier

There is no cut-and-dried answer whether Tomcat standalone or Tomcat+Apache will run faster for *you*. There are far too many variables for simplistic answers to always be accurate. The best thing to do is try your application both ways and see. Just a few examples of how real life confounds answering a question like this: :-) * Many web applications written with servlets and JSP pages are 95-100% dynamic content. If your app is like that, static file serving speed is not relevant, or may not be significant enough to make any difference in overall response time. * Under normal circumstances, thre *browser* will cache static files. If it does so, the fact that Apache might also do so is not relevant as long as Tomcat sends back the "Not Modified" response correctly (Tomcat 4 does this, for example, with zero disk accesses). * You don't want Apache caching the output from dynamic resources (servlets and JSP pages), because the whole point of them is that the contents will change. * You can, in your servlet/JSP page, implement the getLastModified() method yourself to let the browser cache your dynamic pages. This is very useful for "dynamic" pages that don't change very often. Of course, there are many non-performance-related reasons you might be required to use Apache in conjunction with Tomcat (if you need the other functionality that it provides). But, if you don't, you owe it to yourself to see if Tomcat stand-alone runs fast enough before undertaking the extra pain it takes to configure them to run together. Craig McClanahan

I think IE gives you access to the back button, but most browsers don't. There are javascript methods you can use with the new event model, but they won't work on older browsers. In short, writing a catch for the back button can't be handled consistently.

Does Load balancing block requests? Help
Iam working on solaris 2.6, Tomcat 3.2.1 and Apache 1.3.9 with mod_jk I have 5 servlets running and they are load balanced by a load balancing servlet. All the servlets are identical and run on the same machine and use the same class files. Each of my requests takes 10 seconds to process. If i sent 5 concurrent request at the same time. Servlet 1 would process request 1 and wait 10 seconds and then the next request would get processed and so on, it takes a total of 50 seconds to complete the operation.( The whole operation seemed serial and not concurrent as i expected it to be) I was expecting the 5 requests to be processed concurrently by the 5 servlets in 10 seconds. Does the Load-Balancer block What am i doing wrong or is this how it is supposed to work, my backend is a Oracle database and all the operations are selects. Please help

Re: Running Tomcat stanalone without the port number?
If there is not another application listening on port 80 on that machine, you can change the port value for the connector in server.xml from 8080 to 80. That way, the user won't have to type in the port.

Running Tomcat stanalone without the port number?
Hi, when running Tomcat standalone, the URL will contain the port number, e.g.: www.hostname.com:8080/myApplication/index.jsp. Does anybody know how to get rid of the port number when running the Tomcat in standalone mode? Thank you very much in advance. T.
explanation of the container with apache
I'm looking to know how someone would explain how the servlet container interacts with the web server. Things like, what exactly is a container, how requests are forwared to the container, how the connections are made, the overhead, namespacing, etc... Or even point me to a few refs about this.

Possible ill-advised default handling of 403
I just noticed that if I set a 403 error status in a servlet, Tomcat automatically adds the following HTML body with the error: SSL required to access this page Ugh. I looked at the source code (3.2.2 of Tomcat) and notice that if no 403 error-code handler is registered, it defaults to SSLRequiredHandler. IMO, this is a bad default since SSL access is only one of many possible reasons that access to a resource is forbidden. To me, there should be no default, or if there is one, it should be a canned response like "Access Forbidden". So why was this done? A hack for SSL support? And when will it be changed. --ewh -- Earl W. Hood Texas Instruments [EMAIL PROTECTED] 972-917-1695

apache loses mime-type header
Has anyone seen this? The setup is apache 1.3.14 and tomcat 3.2.1 on AIX. The servlet correctly sets the header and with tomcat set up to accept HTTP requests, everything displays fine. However, if we access the same servlet through apache's port, it gets displayed as text/plain instead. Any ideas?

I'm using your SimpleRoleMapper to get started, but I can't get it to work. I can't find in your code where a distinguished name (dn) is linked to roles. In your translateroles function, I can see how users are assigned roles assigned to everybody (*), but I can't find anything like (String[])userRoles.get(distinghushedname) as I might expect. All my users are reporting only a role of [guest] even though I've carefully matched the dn in the rolemapper file to the dn stored by jndirealm. The translateroles code seems to be looking for rolenames as keys in the userroles Map : String items[] = (String[])userRoles.get(ur); Shouldn't this be something like : (String[])userRoles.get(distinghushedname) Please let me know if I'm looking at this wrong or not.

It was tested against LDAP JNDI with Sun's and Netscape's jndi providers LdapRealm authenticates and authorizes users directly against LDAP using Netscape LDAP JDK. These two realms are interchangeable you can switch between them without many configuration changes. According to my tests it performs 10 faster under 20 concurrent threads than JNDI with Sun's LDAP provider. This is not final result because I need to test and tune-up multithreaded access and synchronization there might be some misunderstanding on my part. I also noticed some cases of JNDI loosing connection to the server under heavy multithreaded load while Netscape's LDAP handled it nicely. Because I use LdapRealm for Tomcat 3.2 for my production system it is tested better than JndiRealm. There are four classes in the package : JndiRealm and LdapRealm are for Tomcat 3.2x JndiRealmCatalina and LdapRealmCatalina for Tomcat 4.0 className="com.peacetech.webtools.tomcat.JndiRealm" JNDI TOMCAT 3.2x className="com.peacetech.webtools.tomcat.JndiRealmCatalina" JNDI TOMCAT 4.0 className="com.peacetech.webtools.tomcat.LdapRealmCatalina" LDAP TOMCAT 4.0 className="com.peacetech.webtools.tomcat.LdapRealm" LDAP TOMCAT 3.2x Jndi/LdapRealm uses searchBindDN and searchBindCredentials to connect to a directory. Then it looks for exactly one user name matching searchFilter in searchBaseContext scoped by searchScopeAsString (values are "base", "one", "sub" according to LDAP URL rules) If one and only one matching directory object is found it will use this object and tomcat supplied credentials to authenticate the user. If successful Realm will fetch user roles using JNDI attributes listed in securityAttributes (comma separated directory attribute names). If attributesReadByOwner = "true" Realm will use authenticated user itself to pool the attributes from directory otherwise it will use searchBindDN to retrieve the attributes. If roleMapperClass is specified Realm will use it to map user roles onto application roles specific for each web context for tomcat 3.2x and specific for each defined Realm for tomcat 4.2. Provided SimpleRoleMapper implementation will read role map from either roleMapperSourceUrl (if specified) or for tomcat 3.2x from WEB-INF/role-map.xml file in each web context if no roleMapperSourceUrl was defined (if WEB-INF/role-map.xml file does not exist in a context no mapping for this context will occur). You can use principalAttributes parameter to specify LDAP attributes to be stored in principal so you can access them from your servlets PARAMETERS: jndiInitialContextFactory = "com.sun.jndi.ldap.LdapCtxFactory" (or "com.netscape.jndi.ldap.LdapContextFactory") This attribute for JndiRealm ONLY. It corresponds to javax.naming.Context.INITIAL_CONTEXT_FACTORY directoryUrl = "ldap://207.176.93.66:389" This attribute for both JndiRealm and LdapRealm. If you want to use SSL for LdapRealm you can use "ldaps" protocol: directoryUrl = "ldaps://207.176.93.66:636" You will need to configure Sun's JSSE to use SSL It corresponds to javax.naming.Context.PROVIDER_URL jndiSecurityAuthentication = "simple" This attribute for JndiRealm ONLY.

Is there a way to get the Doc Root
Title: RE: what is this number -2147483646
Hello,
This
may be more of a JSP or Servlet question, but I am sure someone in this group
would know the answer
I have
an Web application /Myapp and I have a bunch of jsps in an admin directory. I am
going to distribute this
in a
generic war file.
So to
access my admin index I would do something like http://host/Appname/admin/admin.jsp
The
problem is I do not know what the end user is going to call the
application(Appname). So How do I get the Document root.
I can
do a path = <%= request.getRequestURI() %> and do some substring
stuff.
<%=
application.getRealPath("") %> doesn't give me what I need. I was
hoping for an application.getPath("")
Thanks
for any Suggestions..

Are you running Tomcat 4 with a security manager (i.e.
"$CATALINA_HOME/bin/catalina.sh start -security")? That seems likely,
given the fact that you're gatting a security manager exception.
If so, you need to grant your JDBC driver permission to create a network
connection to port 3306 on your database host. This is done in the
"conf/catalina.policy" file. There are some notes near the bottom of that
file documenting the way that you add this permission.

problem with mod_jk
Hi, my admin has config Apache to work with Tomcat, she said using Apache + Tomcat together, the jsp/servlets will load faster, but the static pages will "hesitate" for a fraction of a second and then the pages got load up. Also, the size of the log file for mod_jk has increased to 3MB by just using Apache + Tomcat for about 20 minutes. I checked with the mod_jk.conf and mod_jk.conf file, the jkLogLevel is "warn", and in the mod_jk.conf-auto file, the jkLogLevel is "error". Both of them are not on the "debug" level. I wonder why the size of mod_jk.log is that large. So does anyone experience something like that? Or does anyone know how to optimize the performance for both static pages and servlet when using Apache + Tomcat? Thanks in advance.
Upgrade to Tomcat DECREASES Performance?
OK, let's see how good you folks are: I work for a large national not-for profit membership organization. We've got a large database application that we serve to our members from a small group of servers out of our national office. About a week ago, we upgraded our servers, moving from Apache JServ/mod_jserv/AJP12 to Tomcat/mod_jk/AJP13. Ever since the upgrade, our servers have been HIGHLY unstable (our 3 busiest servers have each crashed at least once a day for the last week) and we're HIGHLY confused. The only real change has been the move to Tomcat, which we thought was a large upgrade, but our app has been acting as if we downgraded! Before the upgrade, application was having some performance issues (record locking, result set not found errors), probably caused by the large load on our servers combined with some inefficiencies in the code. After the upgrade, the same performance errors exist, but seem to be magnified, as if Tomcat is working SLOWER than JServ. But here's the worst part: At least once a day (usually after running for a while), the application will simply stop responding - users will attempt to save forms and/or navigate between pages and will never get a respond (eventually they'll get a "Page Cannot Be Displayed Error"). When the server is in this state, we check the running processes and we see lots of java threads loaded and waiting for response, but none of them is RUNNING, so I don't THINK this is a runaway thread problem. Once the server hangs like this, our processor usage by the JVM will go down to 0% and stay there until we restart Apache and Tomcat. Here's our specs: SERVER SPECS (average): Dual Pentiums (1 Ghz) 2.5 GB RAM Red Hat Linux 7.1 OLD CONFIGURATION: Apache 1.3.14 Apache JServ (with mod_jserv and ajp12) IBM JDK 1.3-5 Cloudscape 3.5 NEW CONFIGURATION: Apache 1.3.14 Jakarta Tomcat 3.2.2 (with mod_jk and ajp13) IBM JDK 1.3-9 Cloudscape 3.5 So... does anyone out there have any idea why we're seeing these problems? Where should we focus our investigation? Should we just go back to JServ, or is Tomcat REALLY better?

Help: HttpFilterProc Problem...

Re: Sharing a local setup of Tomcat?
If your organization is using WINS, you should be able to just use http://xxx99x999:8080/ from another computer on your LAN. If not, or if you want connectivity from outside your LAN (if allowed by your firewall), then run winipcfg to find out your ip address, then replace the xxx99x999 with your ip address.

Re: Sharing a local setup of Tomcat?
Tomcat pages are accessed via tcp/ip. So, for example, if your machine ip is 192.168.0.42 then others would open a browser and type: http://192.168.0.42/index.html to get the index page. If your network can translate the network names of local machines and your machine name is "joesbox" then: http://joesbox/index would also work. On Monday 30 July 2001 09:58 am, you wrote: > Hi!

RE: Customize Url Rewriting + QUESTION
HI! Loïc
I am also using the 3.2.3 version, I think i should have a
look at the 4.0 version also.
I think the approach that you are taking to handle the rewriting
is a good one, though i have got a question on that
how do you get to know that you have encountered a url, let me
rephrase it.
Like you have a hunk of a content in which there are a lot
of tags and form acitons now how will your rewriter get
triggered so that it rewrites the urls before it gets out
to the user.
I mean to ask how does your rewriter plugs into the whole scheme of
things

Yes you can, I'm developping a URLRewriter servlet because of the

I
encounter using mod_rewrite alone :(
I Load it on startup and manage myself the url rewriting by using
response.sendRedirect or
myMainApplicatioSerlvet.doGet(request,response) + some simple rules ;)
Using servlet aliasing in tomcat is not as powerful as I expect.
Does tomcat 3.3 or 4.0 use more regular expressions for this?
(I use tomcat 3.2.3).

The answer is YES, using mod_rewrite apache module.
Add it to your or in mod_jk.conf
if you don't use Virtual Host.
example:
RewriteEngine on
RewriteLog /usr/local/tomcat/logs/rewrite.log
RewriteLogLevel 9
RewriteCond %{REQUEST_URI} ^/(.*) [NC]
RewriteRule ^/(.*) /index.jsp?$1 [PT]

The above should be in web.xml (see below).

You need something like: MLBEventInfoServlet com.tickets.presentation.mlb.MLBEventInfo MLBEventInfoServlet MLBEventInfo Now when you go to http://localhost:8080/buy/MLBEventInfo it divides the URL up into: http://localhost:8080 + /buy +/MLBEventInfo ^ context ^ servlet > > > invoker > > > /olympics/* > > > > > jsp > > > *.jsp > > > > > These come from a working JSErv Config (we are converting > form JSErv to Mod > JK) I'm afraid I do not have experience with JServ, maybe others can help you with a more straight forward approach to converting.

Re: Preventing System.exit(0)
Title: Re: Preventing System.exit(0) RTFM. Security managers... http://jakarta.apache.org/tomcat/tomcat-3.2-doc/uguide/tomcat-security.html Why use a SecurityManager? The Java SecurityManager is what allows a web browser to run an applet in its own sandbox to prevent untrusted code from accessing files on the local system, connecting to a host other than the one the applet was loaded from, etc. In the same way the SecurityManager protects you from an untrusted applet running in your browser, use of a SecurityManager while running Tomcat can protect your server from trojan servlets, JSP's, JSP beans, and tag libraries. Or even inadvertent mistakes.
