Stopping Catalina From MBean Server
Hello; Environment : Tomcat 6.0.20 OS : XP Professional 2002 SP3 Is anybody try to stop the catalina engine from jconsole. I have been using Tomcat 6.0.20, and trying to stop Catalina from jconsole. I click "Catalina/Service/Catalina/Operations/stop" on the MBean view. INFO messages are written to the console related with stopping operation like below; . INFO : Stopping service CATALINA INFO : Stopping Coyote HTTP/1.1 on http-8080 But never shut downs cleanly and waits there. If you look at the MBean view now, some of them are removed. WDYT? Thanks; --Gurkan

I got it from the official site (http://apache.skazkaforyou.com/tomcat/tomcat-6/v6.0.26/bin/apache-tomcat-6.0.26.tar.gz). I don't believe Ubuntu has 6.0.26 in any of their package repositories.

RE: Tomcat Java permission issue -- cannot write to file from a webapp.
Thanks for the quick reply, Chuck. As a quick hack, I moved the records.txt file to my home directory (/root/records.txt) and changed the path in my java code as well. Then I restarted Tomcat (just to be sure), cleared the cache of my browser and tried again - only to find the results unchanged. Did I not understand what you meant, or is it something else? An unrelated, but curiously unsettling phenomenon is that on my dev machine, if I quit Tomcat (either by running "catalina.sh stop" or "shutdown.sh"), then obviously the page fails to load. On the deployment machine, on the other hand, I am able to load the page while Tomcat isn't running, and even make changes to the website and see them on a browser. I can only guess that this isn't the expected normal behavior... perhaps I should reinstall Tomcat? (And upgrade to the newest version, as you've recommended.)

Hi Konstantin and Chuck, Almost there, another few steps taken. - No, It was a new installation. I think these extra files you mentioned were a misguided attempt by me to deploy the axis2.war file using the exploded directory format to resolve my initial problem of msvc(tomcat) not being able to write to the file system. I should have created a directory and then unzipped it inside this directory. I've removed the two directories WEB-INF and META-INF. - This file does not exist anymore in /tmp and the error below is no longer being reported. 10-Mar-2010 22:42:52 org.apache.axis2.deployment.util.TempFileManager > > INFO: TempFileManager::unable to delete /tmp/axis2-tmp- > 6334442305603549214.tmp - http://localhost:8080/axis2/ I can now see the validation and administrator link. I added the manager role to the login user for the Tomcat Manager. I can now view the Axis 2 Happiness page and access the axis 2 administration area. When I click on available modules in the axis 2 administrator area i see the following. Is this Ok? I was expecting to see a "soap monitor 1.1" and addressing 1.1 as shown in http://ws.apache.org/axis2/1_3/webadminguide.html. The output is as follows? * metadataExchange : module description not found * mtompolicy : This is the MTOM policy module.

How do I associate style information with the XML file so it's nicely formatted on the screen ? "This XML file does not appear to have any style information associated with it. The document tree is shown below. 42.0 " 2.In the http://ws.apache.org/axis2/index.html page, under the programming model , WSDL 2.0 is listed.

Tomcat Java permission issue -- cannot write to file from a webapp.
Hi,
I'm new to this forum, and to developing for/using Tomcat in general (and a
bit of a novice in programming in general). I tried various websites and
tutorials to rectify my problem, with no results.
My Apache Tomcat version is 5.5, installed on Ubuntu 8.04 through the
aptitude package manager.
My Java version (the one $JAVA_HOME points to) is OpenJDK 6, also installed
through aptitude. I am logged in as root user.
PROBLEM DESCRIPTION:
Please note that on my development machine (a manual install of Tomcat 6 on
Ubuntu 9.10), the problem does not exist. I imagine this is an issue between
versions.
I am attempting to log survey responses in a file called "records.txt",
which I keep in the directory of my webapp
(".../webapps/MyWebApp/records.txt"). To this end, I pass parameters to a
JSP file through the "post" method, and write it to a file thus:
RecordKeep.CreateRecord (record, outfile);
This routine is stored in a JAR file in the directory of my webapp (compiled
as v.1.5). Here is the code for it:
public static synchronized boolean CreateRecord (String record, String
filename)
{
boolean success = true;
try
{
File file = new File(filename);
BufferedWriter out = new BufferedWriter(new FileWriter(file,
true));
out.write(RECORD_START + record + '\n');
out.close();
}
catch (IOException e)
{
success = false;
}
return success;
}
}
When I attempt to execute the code through a browser, I get the following
exception from the line where I try to write to the file (the entire trace
is too long to include):
java.security.AccessControlException: access denied (java.io.FilePermission
/usr/share/tomcat5.5/webapps/MyWebapp/records.txt write)
ATTEMPTED SOLUTIONS:
From
http://www.mkyong.com/tomcat/tomcat-javasecurityaccesscontrolexception-access-denied-loggingproperties-read/
I tried two solutions:
1) Change the grant codeBase "file:${catalina.home}/bin/tomcat-juli.jar"
category of permissions in 03catalina.policy to: grant codeBase
"file:${catalina.home}/bin/tomcat-juli.jar" {
permission java.security.AllPermission;
};
2) Add an additional permission to the same permission clause: permission
java.io.FilePermission
"$${catalina.base}${file.separator}webapps${file.separator}*", "read,
write";
I don't know whether these options are used by default, so I tried running
both ./catalina.sh start and ./catalina.sh start -security to see whether
the security manager might have something to do with it. By this time I was
just groping around in the dark...
Also, I unfortunately can't see whether accessing the server from localhost
might bring different results.
Help would be most welcome, as I'm completely lost, and I need to get this
up and running in a matter of days. Thanks for your time in advance!
Sincerely,
Victor.

Re: tomcat hangs without anything
I have changed server.xml to a ridiculous connectionTimeout value and now it seems to run better. Since I did this for no good reason at all, it is probably not the reason it runs better. Jconsole seems not to be able to connect, although servlet is responsive. I think I probably need to read more about jconsole, but I guess I need to sleep first. For the time being it works now! Thanks for the great help! Your help makes tomcat a lot more sympathetic to me!

Re: tomcat hangs without anything
4) no other server. I uninstalled apache-http and didn't do anything to tomcat config. I hope this is what you ask me for: I am not sure if Tomcat starts to refuse after about 1 min or after a certain no of requests. I would guess it usually takes about 1 min. Not always the same time, though. Not always the same no of requests either. Example: This time I was able to click 10 times on manager/status and list applications before it froze. The next time it froze not even after 50 times. I wrote a line in this email and then it didn't work anymore.

Christopher Schultz wrote: - windows xp - I start tomcat with bin\startup.bat Can you post everything that shows up on the console during Tomcat startup? IIRC, bin\startup.bat leaves the window open and stdout just goes to the terminal. Not exactly. When you start it via startup.bat, it opens another window inside of which Tomcat is running. There, you do see Tomcat's stdout. The problem is that if Tomcat stops or crashes, this window instantly closes, so you may miss the last messages. If you start Tomcat with the command "catalina.bat run" however, then Tomcat runs in the same command window where you issued this command (iow it does not open a second window). In that case, if Tomcat stops or crashes, the window does not close and you still see the messages if any. You can stop Tomcat by entering CTRL-C once in the same window. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Use a servlet instead of a filter, and (to my knowledge) there is nothing stopping you from mapping your servlet to /js/config/my.json In order for the above to map exactly to the URL http://yourhost/js/config/my.json I think you would have to put this servlet inside the ROOT (default) webapp. Then make sure that when this servlet returns the response, it sets the appropriate HTTP headers to forbid the client browser (or any caching entity in-between) from caching the result.

question about single Executor for multiple Connectors
Hi, I am using 6.0.24 with a java 1.6 on an old redhat linux system. I am using httpd in combination with tomcat. All is working as expected but I had a question about something I noticed in my logs. In my server.xml I have set up one Executor and two Connectors (one for port 8080 "http"and one for port 8009 "ajp13"). Below is the relavent portion of my server.xml: maxThreads="50" minSpareThreads="5"/> enableLookups="false" connectionTimeout="6" executor="TomcatThreadPool" disableUploadTimeout="true" /> enableLookups="false" connectionTimeout="6" executor="TomcatThreadPool" disableUploadTimeout="true" /> My question is: when i access tomcat via port 8080 I see in my logs that the thread that handles my request is called TCThreadPool-N as expected, however if I use port 80, though httpd, I see the name of the thread that handles my request is named TP-Processor-M. Does this imply that my one Executor is not handling requests from both Connectors? If not why not? As a follow up, is it possible to configure whatever pool the TP-Processor threads come from?

Re: question on tribes member alive time
On 03/11/2010 01:46 AM, Eddie Hsiung wrote: Hi I'm trying to debug a vendor product which uses Apache Tribes as its cluster communication implementation. I've identified that each member of the cluster derives the "master node" instance using the aliveTime field of all members of the cluster. The member with the largest aliveTime is elected to be the master node. I would not recommend using aliveTime as the elector for master node. The reason for that is cause if the network is busy, then multicast packets can be delayed or dropped all together. So you could end up with masters changing constantly. Instead, Tribes already defines an absolute ordering algorithm http://svn.apache.org/viewvc/tomcat/tc6.0.x/trunk/java/org/apache/catalina/tribes/group/AbsoluteOrder.java?view=log I would suggest using this for the simplest possible master election One thing I notice is that local member aliveTime is only updated when McastService.getLocalMember() is called while (remote) member aliveTime is updated constantly (by a separate thread?). Is this observation correct? If so, does this mean that using aliveTime to elect a master node might run into race conditions if it wasn't implemented carefully? For example, remote member aliveTime is always more up-to-date than the local member alive time. Assuming two members of the cluster started almost at the same time, It's possible that they always think the other member is alive longer (if the remote aliveTime is updated before local aliveTime) and, therefore, think the other member is the master node.

Try verifying that the subsequent requests are actually making it to Tomcat (enable the AccessLogValve in server.xml). What also helps a lot usually in such cases, is using a browser add-on such as HttpFox (Firefox) or Fiddler2 (IE), to see the exact sequence of HTTP requests/responses, and their associated HTTP headers. For example, you would see there if it is really the server sending a 304 (not modified), or the browser just serving the document from its own cache. Or you would see if the response comes from Tomcat or from Apache httpd or IIS or some other proxy, if you have one of those in front of Tomcat (as seen from the browser end). To the browser, the above URI "/(webappname)/js/config/my.json" certainly looks like a static resource, so it would not be surprising if it just cached it the first time, and served it from cache the second time. I have not tested the following, and it is not based on any certain knowledge based on the HTTP RFCs, so treat with caution, but you could try a cheap trick : In the link to that "document" in the html page, add a dummy query string, like : instead of http://servername/webappname/js/config/my.json try http://servername/webappname/js/config/my.json?a=my.json The presence of the query string /might/ trick the browser in thinking that this is not a static page, and force it to re-request it from the server. (And the reason for which I am adding the "=my.json" at the very end, is to get over a nasty habit of IE browsers, who try to "evaluate" the URL and guess themselves what the content might be based on the "extension", instead of believing what the server tells them in the Content-type header). - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Applying a servlet filter to a static resource
Hi, I am using Tomcat 6.0.24 and am trying to use a servlet filter on a static resource and am having some troubles as the 2nd request returns a 304. If I could modify the calling code to hit a servlet instead of the static resource, I could use that servlet to read the static resource (JSON), perform some business logic and modify the JSON, and return that to the client, but unfortunately I can't change the calling url. TestFilter foo.TestFilter TestFilter /js/config/my.json Is there anything I can do to make Tomcat not return the 304 for the 2nd request to my.json?

Re: Disabling http connector
Cummins College wrote: Hi, I know that https by enabling the secure attribute to true. But what if I want to "disable" the http connector? To elaborate, I want the https connector to be disabled when http runs and vice versa. What changes should be done? However, not by changing the secure attribute. We know most of you dont exactly agree or approve of our idea about fiddling with the http connector, but please do help! It is not that we don't /agree/, it is that we can't really see the point, or what you are trying to achieve, or how it could possibly work in the practice. Let me give you an example : Say users start by getting a "menu" page from your site, using a http link : http://yoursite.yourcompany.com/welcome.html Now inside that page which the browser just got from your site, and which is now in the browser's memory, there are links to various things the users can do on your site. For example : sign up as a student cancel your acoount study programs etc... So, when the user is going to click on such a link, the /browser/ will interpret this in function of the protocol and host which was used to get "welcome.html", and for example for the first link, it is going to issue a request to : http://yoursite.yourcompany.com/students/sign-up.html That means that the browser is going to try to set up a connection with the server, using the HTTP protocol, over a non-secure connection. Now suppose that in the meantime, you have disabled HTTP on port 80, and forced it to be HTTPS. Well then, this request from the client is going to fail, because it is still going to try for a HTTP connection, because /that is the meaning of the link it has in the page currently loaded in the browser/. And the Connector on port 80, which is suddenly accepting only HTTPS connections, is going to refuse that HTTP connection request. Changing the connector's protocol is not going to suddenly and magically update all the welcome.html pages which have been already loaded by the browsers accessing your site, and the links in those pages. It is also not going to magically update all the pages on your site which already have these links in them, even if browsers have not received them yet. If you want a client, at some point, to stop using HTTP and switch to HTTPS, then the correct method is not to mysteriously change the nature of the protocol "under their nose". One correct method is to insure that for links which you want to be used under HTTPS, your return in your pages the appropriate link, like : https://yoursite.yourcompany.com/students/sign-up.html";>sign up as a student instead of http://yoursite.yourcompany.com/students/sign-up.html";>sign up as a student Another correct method is, when the browser requests a page using HTTP, to return a "redirect" response to the browser saying : "for this page, which you wanted as "http://yoursite.yourcompany.com/students/sign-up.html";, please use this address instead : https://yoursite.yourcompany.com/students/sign-up.html That is called a "redirect" response, with a HTTP status code 302. Upon receiving such a response, the browser will, automatically and transparently, without even asking the user, make a new request to the server, this time for https://yoursite.yourcompany.com/students/sign-up.html And on the server side, this new request will be received and processed by the HTTPS connector, not the HTTP one. The HTTP and the HTTPS Connector are both set up in advance, ready to received requests on their respective ports and using their respective type of TCP/IP connection, and they do not interfere with one another. If you want to take a Connector which is currently active and using one protocol, and change its protocol on the fly, then please state a valid reason to do this, that we could understand what you are trying to achieve, and which the current HTTP RFC and associated webservers cannot do in some standard way. Note that in the above, I am simplifying the problem which would happen, because switching from HTTP to HTTPS is not just a matter of having a browser being refused a connection. It would also cause any existing live connection between browsers and the server to be aborted, for reasons that would appear mysterious to anyone watching the logfiles or the traffic for instance. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Taylan, I am currently trying JVM 1.6.0_7 per Chuck's suggestion and, so far (4 days), it is working.

question on tribes member alive time
Hi I'm trying to debug a vendor product which uses Apache Tribes as its cluster communication implementation. I've identified that each member of the cluster derives the "master node" instance using the aliveTime field of all members of the cluster. The member with the largest aliveTime is elected to be the master node. One thing I notice is that local member aliveTime is only updated when McastService.getLocalMember() is called while (remote) member aliveTime is updated constantly (by a separate thread?). Is this observation correct? If so, does this mean that using aliveTime to elect a master node might run into race conditions if it wasn't implemented carefully? For example, remote member aliveTime is always more up-to-date than the local member alive time. Assuming two members of the cluster started almost at the same time, It's possible that they always think the other member is alive longer (if the remote aliveTime is updated before local aliveTime) and, therefore, think the other member is the master node. Thanks for any clarification on the subject. eddie
