I was encountering the same issue as Robert and your working theory sounds quite reasonable. I'm in a virtualized environment, too. In my case it is XenServer and the problem occurs only directly after booting. When I manually execute systemctl start tomcat everything is fine. That fits to the entropy thing. In my case it wasn't systemd killing tomcat but jsvc. By default jsvc waits only 10 seconds. After configuring SERVICE_START_WAIT_TIME=90 in setenv.sh, everything is fine now.

Re: Double call to requestInitialized when forwarding for FORM auth
Hey all, I'm the guy who wrote the DeltaSpike code that is causing the trouble here. So maybe I should ask a very concrete question here: Basically the DeltaSpike code assumed that ServletRequestListener.requestInitialized() is called exactly once for each physical request. But it looks like it is called more than once if the user gets forwarded to a login page (login-config, corresponding constraints). Maybe even if requests get forwarded? I didn't check this. Actually I was very surprised about that behavior. The javadocs of ServletRequestListener.requestInitialized() say that the method is invoked when the request *is about to enter the first servlet or filter of the web application.* In my understanding this means that it gets invoked only once even if the request is forwarded. I didn't find anything in the Servlet spec about that specific topic. Any thoughts about that?

Ok, thank you. What kind of notification should we process to detect this transition ? I'm not sure, since it's DeltaSpike which is objecting to the current state of the request. I think you'll have better luck with asking the DeltaSpike folks. They are welcome to come here to ask about why something may have changed. Was there ever a reply to your initial question? Yes, and a patch allowing this double initialization. Hmm. I'm surprised that it wasn't possible before then. But as I suspect that there is something cleaner to do, I try to scratch the subject. In your post to their list, you mentioned that there are sometimes Pretty much the same than in this case, if I sum it up. A typical example : years ago, I wrote a web filter, had to perform some locking in it (because of legacy libs) and was quite surprised to see the request going through the filter twice when serving a login page on FORM auth. I am no JEE Guru, so strange does not mean bad but surprising. A request can be forwarded to another resource during request processing. According to the servlet spec, forwarding a request should send it back through the Filter chain for the (new) target resource as long as the Filter was declared to be run for that type of dispatch. See section 6.2.5 of the Servlet Spec version 3.0, which explains what is going on. - -chris -BEGIN PGP SIGNATURE- Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJVp7GVAAoJEBzwKT+lPKRYVXMP/36fuxmrIIbB4VgRWU92VyjD jgteXXoWHHV8WtCpVZzbhUrUKDG9XE914RK8DfyZyqR+DMQ8ucl4nkygTQP64siP WIylWTlsk+HCvm7u3NKzJgIH6QoyBNlaPbgVdZq+PcvqcXy2evNE1HSIuvy/n7J6 ZDvUsKAcmjj65MC9K+fXwLHI5os3n4R5eVZr9nzG6mMZkIYLCzRGU57QtnMHgtq6 IeaJ4uSjBe8L5E8qN3Y2wlrye0v1LKLYrQn1PTrWYY0r2LhcAJev2HVvozG1L3rw jfpt+5JnJDwyhP15Bo3zRDTvoUkIeHIyUVEcy3sGXtGmCMXQ4MMfu3N4mMkIJPga P5+fCheGoFVZwCwnrfYcjgY/T1sjFISMN90Tb8xQUlew0/iKnBLTQ6HjTUu7zswM rlkuMeqBTE4JZxsU8zhEhBTHhWmHvhfvZVdanxSvUmWWFuBwoHp67ur2CPpoJWh1 FU7HE0+AYgSZPg9ZOXKPTivT6OJi70n5YcpQCYPH2/XreQViBsTNTz3g5u66rEhv P89ohTKOYWmGGqUaOVvXXRIBfMzkGfURZFG6Oi+hQy+LdC2XszlB0EcANSn6ThiG wYKfAp8m87KjDesmATlaRJm9/RzJDO/sFo8rrGyTRpFvapwkvZmgRLmlaeDuhZ2f 6HrvOa7Vijuk93PhqnCd =JjcA -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org -- Christian Kaltepoth Blog: http://blog.kaltepoth.de/ Twitter: http://twitter.com/chkal GitHub: https://github.com/chkal

Yes, but it has nothing to do with Tomcat: you have to do the work
yourself.
I already crawled through the catalina code that is responsible
for the servlet selection and didn't find anything that would allow
this. But this doesn't mean that it isn't possible at all.
Right: this isn't something that the spec requires, and it's usually
not something that the server would get involved with. But, as I said,
you can do it yourself; you have all the tools you need.
As far as I know, java configuration for servlet registration
doesn't allow passing domain names. But maybe there is an option
within context.xml.
Nope.
I want to create a web application that has different domains for
the application itself and its management site. Both parts should
run at the context root, at different domains. The application
needs a shared (spring-)context in which the application's beans
are stored.
If you want to support more than one (DNS) domain, you'll need to make
sure that your application is deployed into a Host that is either
the default Host, or one that matches all of the domains you want to
use. Fortunately, Tomcat comes pre-configured with a single, default
Host that does just that. You have nothing to do but drop your WAR
file into webapps/ and let it auto-deploy.
That's where Tomcat pretty much stops being involved, and you get to
do the rest of the work.
You mentioned that you had two servlets, and you want one to handle
everything to one domain, and the other servlet handles the other
stuff. For the sake of argument, I'll call those domains
management.app.com and everythingelse.app.com.
Let's assume you have these two servlets defined in web.xml:
servlet
servlet-nameApplicationServlet/servlet-name
servlet-classcom.app.ApplicationServlet/servlet-class
/servlet
servlet
servlet-nameManagementServlet/servlet-name
servlet-classcom.app.ManagementServlet/servlet-class
/servlet
... and you have them mapped:
servlet-mapping
servlet-nameApplicationServlet/servlet-name
url-pattern/app/url-pattern
/servlet-mapping
servlet-mapping
servlet-nameManagementServlet/servlet-name
url-pattern/manage/url-pattern
/servlet-mapping
If you want, I suppose you could map the ApplicationServlet to /. It
doesn't really matter.
At this point, anyone visiting your application could hit either of
the two mapped URL patterns to get to either servlet.
Let's assume that all you want to do is make sure that the management
servlet is only available when you use the management.app.com domain
name. Write a Filter that detects the domain name and throws you out
if it's not management.app.com. Map this filter to /manage and you
are done.
That's something I already do (with little variation). The missing step
is just to beautify the URLs.
Or, if you'd like for any request to any URL to go to either /app or
/manage, then you'll want to write a Filter that does something like thi
s:
public void doFilter(...)
{
String domain = // ...
if(.equals(domain))
application.getNamedDispatcher(ManagementServlet)
.forward(request, response);
else
application.getNamedDispatcher(ApplicationServlet)
.forward(request, response);
}
Map this Filter to / and let it handle everything. Make sure you
don't map it to FORWARD requests, or you'll end up with infinite
recursion.
You'll need to grab the ServletContext in the Filter's init() method
and keep it around (as application).
At this point, you can even remove the servlet-mapping elements from
your web.xml: users will have to access the application through your
Filter no matter what.
I already tried an approach with a filter using getRequestDispatcher but
ran into issues with spring-security. One needs to hook up
forward-requests for the security filter. My conclusion of this approach
was, that it works, but a second roundtrip through tomcat is an
overkill, especially with the ugly configuration issues that arise
within spring-security.
I need to find out if it behaves the same way with getNamedDispatcher.
Hope that helps,
Yes it does - at least because you confirmed my assumption that there is
no way to map a servlet to a domain name and tomcat doesn't provide a
proprietary way to do so.
Thankful regards,
Christian

Sharing Spring beans across contexts and domains sounds like there's an underlying requirement I don't understand. ok, I'll try to explain, as aliases won't do what I need. It's an application that can be configured via an admin interface. The admin interface is one part of the webapp. The main application is accessible via www.example.com. The admin interface needs access to the beans within the main application (e. g. to create tenants that live in context scope), that's why I created just one webapp with two dispatcher servlets. One dispatcher servlet is responsible for the admin interface and one for the main application. Until now I make tomcat select them by using a context path for the admin interface. But this is redundant, because the admin interface needs to be accessed via admin.example.com/admin instead of just admin.example.com. I would like to map admin.example.com to the admin servlet and www.example.com to the main applications dispatcher servlet. At a later stage, www.example.com/admin might be used for other admin tasks that must be accessible by users registered on the main site. But /admin is already shadowed. Hopefully I could explain my problem a little better. Yes, that is much clearer. Honestly without having really figured out the details of your explanation, I would nevertheless point you in 2 directions for that kind of thing : a) use an Apache httpd front-end proxy, and use the httpd proxying and/or URL rewriting capabilities to do what you want thanks for your suggestion! The application anyway needs a reverse proxy / ssl gateway, because tomcat isn't capable of doing TLS with SNI. Your proposed solution seems appropriate, although I have to figure out how to cleanly generate the correct urls within the application. VirtualHost *:80 ServerName admin.mydomain.com .. ProxyPass / ajp://mytomcat.local/admin/ ProxyPassReverse / ajp://mytomcat.local/admin/ ProxyPassReverseCookieDomain /admin / /VirtualHost VirtualHost *:80 ServerName www.mydomain.com .. ProxyPass / ajp://mytomcat.local/ ProxyPassReverse / ajp://mytomcat.local/ /VirtualHost thank you for the configuration excerpt! The ProxyPassReverse* take care of re-directs and cookies. But in your admin application pages, you should make sure that your are returning only relative URLs. E.g. if the admin application would normally return a page with img src=/admin/images/logo.jpg / it should instead return img src=images/logo.jpg / and the browser and the proxy should then do the right thing. Or else, you could add an output filter at the httpd level, and rewrite all the URLs on the fly. That is a bit resource-instensive, but I would imagine that your admin application is not one with very high traffic. I believe relative urls are most elegant. My second choice would be a configuration within the application itself when generating the links (it's using spring and version 4.2 gets support for base uris). A content filter at httpd level seems a bit brittle to me. Note also : in the schema above, there is nothing which prevents a user on www.mydomain.com to request a URL like /admin, which could lead to accidents.. You may want to add a RewriteCond/RewriteRule in that VirtualHost which prevents them doing that. Thank you for the hint - I already prevent malicious access at the application level. The setup is a bit more complex than I described here, because it is a multi tenant and multi domain application. Tenants get recognized by the domain within a servlet filter, that's why they play a big role already. At a spring security layer authorization gets checked for every request.

Re: Using the bin/daemon.sh script on ubuntu.
Thanks for the great responses.
@Ognjen: Yes, currently we also use the setenv.sh (because it will not be
touched by an update).
The *ln -s* Tipp is not bad.
But the problem is, it stores the files in the folder (/opt/tomcat/logs).
On our (AWS) installation we have limited space on /opt, therefore we
attached an EBS volume to /var/, - otherwise we would get problems with
the log files. Now it can grow above some GB.
But because the log dirs are defined in the logging.properties (what get
shipped and overridden by updates) we put this hack into our setenv.sh:
sed -i 's/${catalina.base}\/logs/\/var\/log\/tomcat\//g'
\/opt\/tomcat\/conf\/logging.properties
This will replace the sting *${catalina.base}\/logs* with */var\/log\/tomcat
* everytime setenv.sh is executed.
Now we will never forget to touch the logging.properties after an update.
But i still think it is not that elegant...

Christian.

I set JAVA_HOME, CATALINA_BASE and CATALINA_HOME environment variables in
/etc/init.d/tomcat (which is a copy of daemon.sh), but I guess there may be
a better place to do that.
This link [1] recommends to put environment variables in

Create file $CATALINA_BASE/bin/setenv.sh:

Maybe something like:

User 'tomcat' is already specified in daemon.sh, though you may override
that with $TOMCAT_USER environment variable.

Re: Tomcat hangs every day
Hey, I'm also not an expert for HttpClient, but when creating connections to remote services it is usually a good idea to set connection timeouts and socket timeouts so that the client doesn't block forever if there are problems with the connection.

Policy files
Hello there! I am using tomcat as an embedded container for a while now, it is really amazing, but now I got stuck on a topic. I am implementing a testsuite for automatic testing of uploaded solutions by students. The deployment works like a charm, I also found your StuckThreadDetectionValve very useful to kill threads of the students applications. The next assignment will involve some areas where I would like to specify a policy file so that the students can't do anything they aren't supposed to. Now to my problem. One thing is that I want a policy file to be in the students projects, so that they actually get the exceptions when they are doing something wrong. What do I have to configure in these student web projects so that they can e.g. deploy the project directly from netbeans to tomcat and have the policy applied? The other thing is that I want the policy file to be in my testsuite project and configure it on demand when deploying the student solutions. Currently I create an instance of StandardContext for each student web application, then I configure the context and finally add it to the host of the server. What do I need to configure, to apply the policy in this case? I hope someone can help me with that, thanks in advance! -- Mit freundlichen Grüßen, *Christian Beikov*
Fwd: Re: Policy files
Accidently mailed on tomee-list before Thanks for the quick answer but it seems I didn't explain my situation completely. We use Maven for all assignments, I can control what base project they have to use for a specific assignment. Also in my testsuite I automatically build these projects and deploy the artifacts to my embedded tomcat. The problem is when it comes to the policy files. Where do I need to add the path to the policy file for the base maven projects of the students? Is there any option in context.xml or so that I can use? The second problem is that I want to configure the policy for each student project when deploying on embedded tomcat(since the students could change the file in their projects). Where do I have to configure the policy when instantiating the StandardContext myself? I saw that the Loader of the context is of the type WebappLoader and the ClassLoader is a WebappClassLoader. I also found a method addPermission in WebappClassLoader, but I don't want to parse the policy file myself and add the permissions one by one. Isn't there an attribute to set the policy for that class loader? So to summarize it a bit, I want to know what to configure in e.g. context.xml(if that is the place where to configure the policy) to have a specific policy applied.

Re: Policy files
Yes we are talking about security manager policies. So there is no possibility to just push the policy file to the WebappClassLoader? As stated in the reply to Matrin Gainty there do exist methods to restrict the webapp, but unfortunately no method for supplying a policy file. So this means I have to parse the policy file myself and add the permissions manually to the classloader? Are there any options in the context.xml I could set for specifying a webapp local policy so that I don't have to fiddle around with how tomcat is called? I know how to apply a policy at runtime, but don't know how this affects tomcat when I apply it e.g. in a ServletContextListener. Would be cool if there was an option to do that kind of stuff.

What do I have to configure in these student web projects so that they can e.g. deploy the project directly from netbeans to tomcat and have the policy applied? I assume you are talking about SecurityManager policies. Unfortunately, the SecurityManager applies to the entire JVM, so you can't do something cool like allow one ClassLoader to run amok while classes loaded from another one are constrained. Instead, you can place limits on the entire JVM (e.g. no System.exit) and then poke holes in those protections for trusted content -- usually a specific JAR file, etc. If you are going to do that, you need to attempt privileged actions everywhere your driver code is going to do something that requires such privileges. If the student code tries to do something forbidden (e.g. System.exit), they'll get a SecurityException. If you try to do it without a privileged action, you'll also get an exception. The other thing is that I want the policy file to be in my testsuite project and configure it on demand when deploying the student solutions. Currently I create an instance of StandardContext for each student web application, then I configure the context and finally add it to the host of the server. What do I need to configure, to apply the policy in this case? You have to apply the policy when you launch the JVM via system properties on the command-line. Fortunately, all of your privileged code should be known in advance, so you shouldn't have to adjust anything for student-submitted code: all their stuff is limited by your policy. Remember that you have to give Tomcat all the privileges *it* needs as well as your own code. Check the catalina.policy file to see what privileges are necessary to properly run Tomcat under a SecurityManager. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJReBLUAAoJEBzwKT+lPKRYzOAP/iEB1IPyKjSSY/74IjYqR31G wzF6/HuEzwauYgdCxugxFhiogskUsHGnbgKtd4I0hGRtXwfLQf02c5foR6pV04F3 dy4ViYvXTvTLgM6YqcqDEClFigfJdRZdqb26bRUvbrSacTAgp6ifm2Tc7yBpkcR2 rWo0/zdCQTATHlryKnAtfpx0jngoXmyMxrNVH1efw36zN/C50zq26ri9VMG9vEcE TOy8w8lscj8PaCKj5e0skgvwKWjGrH4gplLOW07STK0Mtpb4rfSL5iua73CoaPsD PvnzlfgJsYWhlzWF6mExKlTDP+9UmC1195VSfVb3yPdSREf+Lk+PcpAIRnqj4Zma ZAQys1LcM5CUPzq4y6T4dokGDIXpwsBaphN7S4MKDp+vgb2W0Z6UbidjkUHiZ25r 1dPbt67f3Ro6gYRO/ggorc9y5/0yYs6xjaA9SuM7xvm4uGG4lEn092f6FBnd0+OZ 7t/6IylDSP5+CxCmXrPBu9TeJppq42biVz8VJaM+BJjlDKU6BIn+P2qPR/N1C2QK wR8aSbcxzKWekSkLv5VCnErCDbx+YekMWVfVfuQobQkMIha977cBHlqc+jhioG2g QIHaMAPA6JQMEQdSHrob98QirBI9FfZSDDdWQ/w9BuaAT3+bXXPKvUvgbLz14vN+ CLya7aynTMumUFHBnnv2 =MeqU -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Policy files
Well I understand that there is only one SecurityManager per JVM, but as you mentioned I can restrict actions for specific CodeBases. This is what I am actually trying to do. I want the student web applications to have only a hand full of permissions defined in a policy file. I think I explained my self wrong earlier. The policy file I am speaking of, the one I want to apply to student projects, is more like a set of permissions that I want to give the web applications. I mainly want my testsuite and everything packaged with it to have all permissions. Generally the student projects should have no permissions. I want to give these applications only a minimal set of permissions, only the ones they actually would need to fullfil their tasks. The WebappClassLoader supports the method addPermission(Permission) which is nice somehow, but I don't want to hard code the permissions but rather have them in a policy file or so. The reason for having the permissions in a policy file is mainly because I thought I can configure something in context.xml so that the policy file gets picked up by tomcat. I just don't want to have these applications running on my computer not knowing what they actually do. To be honest I couldn't think of any permission I would give a student application. The libraries that can be used are predefined, so I give these jar files the permissions for reflection or whatever they need to work properly. Am I simplifying the whole thing and is what I want much harder to achive than I think?

I think I'd have to understand more about what you are trying to do in order to be helpful.

You can do it on a per-codebase basis, but you have to know the URL(s) of the codebase(s) in advance. Would be cool if there was an option to do that kind of stuff. Yes, I rather think it would be cool to specify a security policy on a per-ClassLoader basis, but there are definitely some thorny issues there otherwise I think Sun/Oracle would have implemented that capability by now. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJReD6oAAoJEBzwKT+lPKRYDGAP/R9SjzcX0ENxQ5A7/N+S26M8 Jd5sNOisQ9mdVowygJAwppYDqtUalmMZ5qZTtsyYZYWKn3QpiML10Qr36elFZsA5 zoCA1JRB+hwC/vhNgJGdhhNxDOEQo66mfiJlfQ0rHpOGwVrGppAuSV4kVfX5aZCQ 9Ssq2HZvfLE7tL0pg+qnBT1AA9/HU+hAmk4GkCETSMR16jB8NrwI10ejU7gt1F4F BaUCULZvYtLRelbsAQTfz4ZOQL0FZq2zD85BeZ+hey0koinpr+nY1aRGy4ASbmrM Eke8ruYKW5xbVmSyQ0A4JmaYmMrYFfc7SgdR7UOkD21wbHA87fSHF9oNhhom2Tqd Qsdn89swuBwp6XkS1akbfRc6RJ4WPCxNfxBWceGWlJewtgY8XRD8lPYOsHCSiVN/ SOSVnmCaa8Fs6ygk75wo6IKI+VlLRJqFSK5pr1iGK9hVC+xgBGB5APrhMhvSCUmO SuP6IxFMSRDhghlxUbDhd7hW7KZnpXGQCJZjSoEsW/ysjhwy0hfhLbkEGTyYV8Az wCap5r3eHc5KsHP0FK9F283DbiUhV8oHoLK0ddzKd9KrHbxap4Vekk2tqbUA52Vn gpcRk5vodI88w0mvtdc9b57luHPedmY87bqmayjqzh6VHixlT/O8+CQhmJLRrln3 Wf6YgQg1Li6p//YLwHpo =TJPJ -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org Mit freundlichen Grüßen, *Christian

Re: memory leak in tomcat
Hi Warren, thanks for the help. I found that the application creates lots of SessionFactoryImpl objects even though one is enough I changed this part of webapp. Now it has only one SessionFactoryImpl and the memory leak is gone. bye 2012/5/24 Warren Bell warrenbe...@gmail.com Is this the same server with the Wicket app you posted about earlier ? If so, you have a Wicket app that is storing the SessionFactoryObjectFactory on a page as a class member. Wicket stores each page a user has been to in the user's session. If the page has class members, then it serializes them and stores them too. I have seen this kind of thing happen many times before causing big memory usage. Remove the Wicket app and run the Eclipse Memory Analyzer.

It is just a web application requiring a lot of memory. WebappClassLoader is the classloader that is used to load the classes of your webapp. Of course, it remembers every class that it loaded (to satisfy repeated class.forName() calls) and every class that it loads has a reference it it (via getClass().getClassLoader()). There may be many classes, but I do not think that the classloader itself is responsible for 300 Mb of memory. and the data that is in the entries of the gigantic Map is org.hibernate.impl.SessionFactoryObjectFactory That would be a hibernate question.

Re: getting frustrated with web sockets
Hello Ravi, I do not use Requests or sessions. Since I have the Message-Inbound object I can directly store in it for example with private fields any session attributes I want. I do it this way, that the message Inbound implements my GameSessionParticipant-interface which has access to a gameSession Manager which is created by the servlet. I need my own session handling because not just everybody talks to everybody. Instead the users form groups and these are handled by the session manager.

So there isn't one thread for each websocket client used? For the BIO connector it is always one thread== one connection. You cannot do non-blocking IO with the blocking IO connector. For NIO and APR/native is: - as many connections as you like up to maxConnections - one thread== WebSocket frame The threads are taken from the connector's connection pool and are returned once the WebSocket frame has been read. Reads are non-blocking between frames but blocking during a frame (to save having track detailed state between reads) Writes are always blocking. In short, if the client isn't sending any data, Tomcat doesn't allocate a thread to read it. The poller monitors the connection and passes it to a thread when there is a message to read. If not. What are the configuration possibilities for that? maxThreads, maxConnections on the connector just like HTTP. And how to do it? Use the NIO or APR/native connector and it just works. Perhaps you can describe more deeply how you handle websockets in regard of blocking/non blocking and thread handling? See above. If you want more detail, look at the source code. I am not going to translate that into pseudo code for you.

Re: getting frustrated with web sockets
Hello, I had the same problem some time ago. I could get jwesocket to work either. But I then used autobahn: http://autobahn.ws/developers/autobahnandroid/installation That worked great for me. I couldn't find out if the different client libraries do something wrong or tomcat but I was a bit disapointet, too. Perhaps that gets better when the draft is finished. Btw. for normal java I use asynch http with netty. Bye, Chris Am 02.06.2012 04:38, schrieb Ravi: I am trying to build an android app that connects to tomcat web sockets. I need a few java classes that can interact with tomcat websockets. I have tried 3 different implementations (strumsoft, jwebsockets and something else also) but neither one can talk to tomcat correctly. The issue seems to be protocol incompatibility between tomcat as server and any existing java websockets client. I even compiled jwebsockets swing based test client and that also cannot talk to tomcat. Surprisingly all javascript based clients can talk to tomcat, only java based cannot.

non blocking Websockets?
Hello, as far I understood, the websocket implementation of tomcat is using one thread per client. Is there also a possibility to configure it to use non blocking IO?

Tomcat in CentOS 5.5
Hi there, I am new on this list, so first I want to say hello to you. But now to my problem. We develop software for the touristical branch which runs mainly under CentOS. Our customers are big companies. Of course they have SLAs with their server providers, so they cant use any software version they want. CentOS 5.5 ships Tomcat 6.0.18, so this version is available at customers site. The developer who writes the java parts of our application told me, that we cant use the Tomcat version shipped with CentOS, because it has too many bugs. But if we use another one, we break with customers SLAs. I might be true, that there are bugs in Tomcat 6.0.18, but CentOS is an enterprise operating system. I can not believe that these bugs are not fixed with patches there. Can somebody shed some light into this?

hello, i installed tomcat 6.0.24 from the repositorys on ubuntu server 10.04 with this installation guide: https://help.ubuntu.com/10.04/serverguide/C/tomcat.html i can access the index.html on myserver:8080 and can run the example servlets. i updated the |/etc/tomcat6/tomcat-users.xml |with an user admin and the roles admin and manger. But i cant get access to the manager page. My webapp (geoserver.war) doesn't run at first, but seem to work now (is actually runing) What is my fault, does anybody know? smime.p7s Description: S/MIME Cryptographic Signature
Re: another UTF-8 problem
Thanks for your responses. The problem was not the response from the web service. Something must have been completely mixed up. I set the Java option -Dfile.encoding to utf-8 which solved the write to file problem and also put this in the code: if (req.getCharacterEncoding() == null) req.setCharacterEncoding(UTF-8); res.setContentType(text/html; charset=UTF-8); res.setCharacterEncoding(UTF-8); Which solved the encoding of the response I got from the servlet.

You may have to use a profiler to verify that the characters in memory are what you expect them to be.

So, when you use your own command-line app as a client, you get a different response from the SOAP server than when you use Tomcat as the client? You should look at the requests that are being sent. Perhaps there is a bad accept-charset header or something (although that probably shouldn't affect the XML response, since an XML parser is pretty much required to support UTF-8). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxz7SoACgkQ9CaO5/Lv0PCNOQCeLLBz/6e3QNsPyQtw4Ggfnh7R sYsAn3PNB9UqJDunLDeMyQrz6a3Edbao =/0N2 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I downloaded and installed ODE on Tomcat 7, configured it for MySQL, and was able to reproduce the above error. (Contrary to popular belief, there is no space in the error message - that was just a figment of whatever transposition mechanism the OP used. The grammar in the message is flawed, though.) Luckily, there's an easy fix (or at least a workaround): get rid of the original .war file. Once Tomcat has expanded ode.war into the ode directory, the .war file is no longer needed, and in fact is somehow interfering with the use of the directory. Deleting the .war (or changing the extension) lets the META-INF/context.xml file get processed, thus defining the JNDI data source. The same effect can be achieved by placing theContext element in conf/Catalina/[host]/ode.xml, which will override any in META-INF/context.xml (in either the .war file or the directory). I have no idea if things are supposed to work this way, or if this is a bug in Tomcat 7 (haven't tried ODE on any other version). Perhaps the lack of a context.xml file inside META-INF of the .war causes Tomcat to ignore the one in the expanded directory. I tried it that way and at least it seems, as if tomcat recognizes the database. But now, I get another error (see end of message). Do I have to import the ODE schema even if I want to use the database for ODE external data? As a side note, I found two problems with the ODE 2.0 beta: 1) It doesn't shut down properly. You can't use Tomcat's shutdown.bat (or .sh) script to stop Tomcat, since ODE starts extra threads and fails to terminate them when the webapp is being stopped. You can use a signal (CTRL-c on Windows) to get the JVM to shutdown cleanly. Better then the bugs, happening with 1.x :-D 2) The ODE instructions specify the wrong name for the SQL script to initialize the database; it should be sql/mysql.sql, not ode_openjpa_mysql-1.3.2.sql (the latter appears to be some ancient name). Can't find this location. :-( Do I have to change something there?

You should particularly consider upgrading Tomcat and HTTPD. Apache 2.2.3 etch11 is the latest etch version as this tomcat was the version that came with the openbd-installer I want to try it with this one. (support for Dummies) I will assume for now, that you have a sound reason for deploying HTTPD and Tomcat at the same time, rather than just letting Tomcat do all the work. If you'd like to know more, ask. In some newsgroups I read, that tomcat is slower than apache, so thats why I wanted them both.

The above is very bad practice and likely to lead to you exposing data that you shouldn't. JSPs and other content should not be mixed in the same directory. Context should not be defined in server.xml. The debug attribute isn't used anymore. If you have to use both HTTPD and Tomcat, construct a directory structure like this: All static content should go here: /var/www/www.testdomain.org/htdocs/ All java webapps should go here: /var/www/www.testdomain.org/webapps/ Servlet Spec webapps and other java applications are deployed, one each, in a directory inside the above. e.g. /var/www/www.testdomain.org/webapps/ROOT /var/www/www.testdomain.org/webapps/myapp /var/www/www.testdomain.org/webapps/another_app ROOT is the special name for the default application, which is what you were attempting to do with the path= attribute. as done above?! p Thanks a lot for your support!

*** SPAM *** Tomcat NIO : CometProcessor
Hello, I just tried to use the tomcat nio and wondered if it is possible to use client and server pushes through the same socket connection? Or if I have to establish to connections for that purpose. In the end the client should be able to receive notification from server (server push) and also be able to request certain things. As I understood the Low Latency HTTP document it should be possible. Has anyone any advice for me, currently the connection gets closed after the second request from client with error CLIENT_DISCONNECTED.

Re: Memory behavior: Tomcat versus Jetty
Tim, thanks for the hint with the BodyContent. Mark, thanks for your hint to take heap dump. On this morning the two Tomcat instances were using 200 MB more memory than the Jetty instances do. So I thought it's a good time to take a heap dump. In the heap histogram in jhat I saw a big difference between the BodyContentImpl (class org.apache.jasper.runtime.BodyContentImpl) counts: Jetty: 43 Tomcat: 768 Suspicious! I've take a look at this code and the first thing I've seen was, that since Jasper 2.1 BodyContents won't reset its buffer by default. (see BodyContentImpl.clear()). The second thing - what's responsible - is the change at org.apache.jasper.runtime.JspFactoryImpl. JspFactoryImpl in Jasper 2.1 now caches the PageContext-objects per thread. A PageContext-object have an array of BodyContents and so the memory the buffers of these BodyContents reserved will newer be freed until the thread will be stopped and garbage collected. Until today I were using the default connectors with the maxThreads parameter, which newer shutsdown a thread. So the BodyContent's buffer were growing and growing, because we have some tags which generates much output, and would never be cleared. Now I am using a separate thread pool (executor), which cleans up the pool when a thread is idle. And now the memory behavior is almost equal to Jetty. Christian Tim Funk schrieb: If you use JSP tags where the JSP body does not directly stream but needs buffered for the tag to finish processing it (using BodyContent) - then tomcat will allocate and reuse these. If you are creating pages with large body contents - this can take *A LOT* of memory. The rational is to reuse these instead of letting them go to the GC. But there is a way to not have tomcat reuse these. http://tomcat.apache.org/tomcat-5.5-doc/jspapi/javax/servlet/jsp/tagext/BodyContent.html -Tim Christian Stöber wrote: Hello list, we are about to migrate our webserver cluster from Jetty 5.1.14 to Tomcat 6.0.20.

Tomcat 5.5 and Windows Vista x64
Hello together, I'm trying to use Tomcat 5.5 together with Windows Vista x64. Firstly I downloaded and installed Java JDK 1.5.0 and JRE 1.4.2. After doing that I got Apache Tomcat 5.5 from the server and installed this as well. Tomcat Monitor is starting but localhost:8080 was not found (in server.xml this localhost is named). On my x32 system (Windows Vista) everything is running fine. Do you know what I have to change? After that I tried the x64 versions of tomcat5.exe and tomcat5w.exe. These are not running at all. Do you know why? Thanks Christian -- Pt! Schon vom neuen GMX MultiMessenger gehört?

Servlet Caching
Hi there, I am currently investigating a problem with our web app (Tomcat 5.5.23, Java 1.5, JSF 1.2) where the servlet cache does not always get updated when a JSF include is changed. This happend after changing an included JSF. The JSF-snippet that includes is: html [EMAIL PROTECTED] file=/pages/inc/head.inc% f:view [...] body [EMAIL PROTECTED] file=/pages/inc/bbs_header.inc% h:form [EMAIL PROTECTED] file=/pages/inc/menu.inc% [...] The JSPServlet config in web.xml: servlet servlet-namejsp/servlet-name servlet-classorg.apache.jasper.servlet.JspServlet/servlet-class init-param param-namefork/param-name param-valuefalse/param-value /init-param init-param param-namexpoweredBy/param-name param-valuefalse/param-value /init-param load-on-startup3/load-on-startup /servlet Adding development=false and checkInterval=30 to the parameter list did not change anything.

Re: [programmazione] Servlet Caching
Thanks a bunch Luca. I inherited quite some messy code before the old developer said goodbye. So far the big architectural issues in the Data Access and Logic layers have been cleaned up, but the problems in the view still exist. I will live with this issue for now and refactor the view later to use JSF subviews instead of static includes. Best regards, Chris Luca Cicale wrote: Hi, [EMAIL PROTECTED] is a static include, that is at compile time the compiled code of the INCLUDED jsp is simply copied. But if you change a included jsp/servlet after the INCLUDING page has been compiled, well, nothing happens in the INCLUDING.

Re: is it possible more than 1 tomcat in single system?
Peter Crowther skrev: From: Edi [mailto:[EMAIL PROTECTED] consider, i had 4 java application running in one tomcat, if one application crashes, all the other 3 application gets crashes. right? Correct. But it's not always that simple :-). It's your choice how you want to split up your applications between different containers (Tomcats in this case) to trade off memory use vs reliability. You might get a *less* reliable system by splitting up the applications into separate Tomcat instances, though. Each Tomcat runs in its own JVM, and each is allocated a maximum memory size. If you are not careful when tuning the system, you might find that one application in one Tomcat/JVM runs out of memory although there is plenty of spare memory in the system. If you put them all into one Tomcat/JVM, the applications all use the same (larger) memory pool. And what happens if you get one rough application stealing all the memory? probably all your applications will stop functioning.. For me it is always better to have 1 application crash, then 1 it is also easier to see which application is the guilty one if only that application crashes.. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: is it possible more than 1 tomcat in single system?
search your tomcats server.xml file for 8005 and you will se that this port has been declared at the very top Server port=8005 shutdown=SHUTDOWN this is the so called shutdown port, you just have to change this in your second tomcat to for example 8006.

interrupting a multipart post request?
Hello,
I'm not sure if this is tomcat or general servlet issue. I hope you can
help me anyway.
I want to interrupt a multipart post request (e.g. if the content-length
exceeds a given limit). The problem is, that the client seems to
continue sending the data to the server and gets no response from the
server until the whole data is send.
Please see the following doPost method. On the console the exception
appears immediately, but a takes much longer until I can see the
response in the browser.
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
if (request.getContentLength() 100) {
throw new ServletException(request limit exceeded.);
}
}
The same thing if I try to forward the request via the
RequestDispatcher: the request is forwarded when the whole data is sent
to the server and not immediately.
I am using Tomcat 6.0.16 with jdk 1.6.0_04 on windows xp.

If this is a matter of starting a timer after a read from the socket, why should this not be supported on Solaris? prepost_timeout is similar to connect_timeout, but it is used in the situation, where the connection has already been established for some previous request and we are going to reuse (what we are supposed to do a lot, because AJP13 uses persistent connections). We send a cping and wait for cpong before each request when prepost_timeout is set. Such behaviour is very common with other persistent connection technologies like e.g. database connection pools. Does prepost_timeout actually work even though the underlying TCP connection can not be established? See above, prepost gets used when we reuse an established connection to make sure, that the backend is still there and able to answer. I have tried prepost as you suggested in your first reply but it had no effect because of the reasons you just explained. Upgrading to mod_jk-1.2.26 also had no effect.

problem with mod_jk and tomcat-host downtime on solaris
Hi, I use apache-2.2.4 together with mod_jk-1.2.25 to load balance a bunch of tomcat-5.5.25 servers. All servers are running on Solaris 10 and are implemented as zones. The setup works really good during normal operation. But when a server dies for some reason, and with it the zones running tomcat, mod_jk does not stop sending requests to the unavailable tomcats until the operating system times out the tcp connect. This takes more than a few minutes. Reading the documentation suggests that socket_timeout is the appropiate setting to deal with this problem but does not work on Solaris. I could not find any usable settings in Solaris itself, so I am hoping this can be solved with mod_jk configuration. What is the correct way to have mod_jk recognize the tomcats as unavailable more quickly on Solaris? Below you can find my current mod_jk configuration. Thanks Christian # # default worker list worker.list=escenic,jkstatus # worker template worker.template.port=9009 worker.template.type=ajp13 worker.template.lbfactor=1 worker.template.socket_keepalive=0 worker.template.connect_timeout=1 worker.template.reply_timeout=4 worker.template.connection_pool_timeout=30 # workers definition worker.escapp1.reference=worker.template worker.escapp1.host=apppubl1.online.local ... ... ... # load balancer definition worker.escenic.type=lb worker.escenic.max_reply_timeouts=3 worker.escenic.balance_workers=escapp1,escapp9,escapp3,escapp4,escapp5,escapp6,escapp7,escapp8 worker.escenic.sticky_session=1. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
