Tomcat 5.0.28, Socket hanging on sending 20KB data for 16 minutes
Hi I'm using Tomcat 5.0.26 that comes with JBoss 3.2.5 with default configurations A servlet creates pie/bar charts using JFreeChart. This is refreshed every 5 seconds via javascript refresh in the brower. All this has been workign fine for most customers. Suddenly for a specific customer sessions coming from a specific newtwork/georaphical location we see that the 5 seconds chart refreshes are hanging the thread. Charts are 20 KB. For a single user in the system sometimes these requests are talking up 20 ~30 threads and each stuck for 15~16 minutes before it finally clears up. We ran ethereal on the tcp packet and see that when the threads are hung, browser is sending FIN, ACK eventhough server hasn't completed sending the data. Thus we see TCP retranmissions of same packets as its not receiveing any ack from the client. How do I troubleshoot this issue. System is not memory starved and cpu is 98% idle. Any pointers on trouble shooting this would be greatly appreciated.

looking at http://www.jfree.org/jfreechart/javadoc/ , org.jfree.chart.encoders.EncoderUtil.writeBufferedImage does not look thread-safe. try checking sun.awt.image.codec.JPEGImageEncoderImpl.encode API. Try increasing the latency by re-requesting the servlet every 30 secs/ 1 min and see if that works fine or not.

Re: tomcat response slow
Undeploy the other application and make sure that the problem is caused by the new application or some changes in older one. Also check the database for performance. There can be many reasons like, the buffers may not be configures correctly to share the load etc on the db.Aslo check that whether the application is spawning too many connections and also check whether the uptodate driver is used. offcourse People won't like big images bcos it takes long time to load.Better u send log messages from the server in TEXT format On 5/19/06, Rajeev Jha [EMAIL PROTECTED] wrote: what does the logs say? turn debug on and check the logs.

Tomcat 5.5 / Apache 2 / Join (Tomcat-) Session with SSL-Session / Which mod should be used?
Hi! Two question, one problem. I've an application running on tomcat 5.5. And before it apache is running. The primer aim is to join tomcat application session with ssl session to avoid session hijacking. 1.) Which mod should I use? Configuration: Apache and Tomcat are running on same pc. I expect low traffic, because it's an intranet application. I've read about mod_jk, mod_jk2, mod_proxy [1], mod_proxy_ajp [2] According to Apache FAQ [3] and JBoss FAQ [4] only mod_jk or mod_proxy_ajp should be used. What are the differences? 2.) How to join application and SSL session? I've read in an old tomcat-apache-ssl documentation [5] that mod_jk is able to forward SSL session information to tomcat. So I wonder, how configure tomcat using ssl session as application session. Perhaps you can help me.

Re: Tomcat 5.5 / Apache 2 / Join (Tomcat-) Session with SSL-Session / Which mod should be used?
Hi! 1.) Which mod should I use? mod_proxy (is a supporting library in apache, which I think you need to load in order to use mod_proxy_ajp or mod_proxy_xyzanything). The advantage seems to be, that it's easier to configure. 2.) How to join application and SSL session?

Re: Tomcat 5.5 / Apache 2 / Join (Tomcat-) Session with SSL-Session / Which mod should be used?
Michael Decker wrote:
The AJP protocol will convery the SSL information to tomcat fairly
seamlessly, the idea being from the web-app's point of view it can't
tell the difference between an Apache fronted HTTP session and one
coming in via a AJP connector.
You mean, that the session will be created by apache not by tomcat?
We're getting ambigious here. Maybe I should have used the term HTTP
request response cycle instead of HTTP session.
An SSL session to me is a single TLS/SSL connection that securely sets
up a network connection to exchange data. At the start of this a key
exchange is done and the SSL session data maybe cached by mod_ssl into a
file like /opt/apache/logs/ssl_scache.{dir,pag} for later use. SSL
session data can be seen with:
openssl s_client -connect www.yourdomain.com:443
However I think the only session you are really talking about, is an
application session which is generally what HTTP Cookies are used for.
My problem is, that the application session (set by cookie or url
parameter) is not associated with the SSL session. And I hope, there is
an easy way to that.
I dont understand why you want to connect to two (under my definition of
each explained above). It is not normal to connect the SSL session in
this way, as the HTTP protocol may (or may not) use the same SSL session
details during the next request, the client may (or may not) support
persistent connections. The SSL session cache is a performance
optimization, not something an application gets to see or use directly.
It more normal to issue client certificates to your userbase and
validate those certificates with a per-website certificate authority.
In which case the certificate will have an Issue Number and it is this
issue number you can use as an authentication token (providing the
certificate has passed validity testing, I'm sure both apache and tomcat
can help with your application specific validity rules).
Even if you have a self-signed CA on your website a regular Cookie based
login mechanism should be secure enough for most applications. The
JSESSIONID cookie is the primary mechanism for session handling with
most containers.

javamail for numerous mail servers on tomcat
Hello world, I'm trying to use javamail api in order to fecth/sen mails in a tomcat servlet. Sor far, it's fine. more : it works. But my needs are going beyond this firsyt step. As i understand, the mail servers (smtp, pop, ...) are defined as resources in tomcat (or watever servlet) in its specific config file (server.xml). Then the servlet is able to retrieve one of these server throught a context, a session and a transport objects. Right? 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). Applications should never construct instances of SMTPTransport directly. Instead, they should use the Session method getTransport to acquire an appropriate Transport object. (see : file:///C:/lionel/dwd/sw/javamail-1_4/javamail-1.4/docs/javadocs/index.html?index-filesindex-1.html) So i'm wondering how i should use the Session method getTransport to acquire an appropriate Transport object.

Re: JSSE13SocketFactory in a 1.5 JVM and SUN-SPECIFIC classes
Thanks for the quick response! I think I've discovered some more problems while looking into this class and references to it. JSSEImplementation contains code to select the correct factory based upon the JVM version. However, it appears that there is a typo in the class name. IIUC, this code in JSSEImplementation: static final String JSSE13Factory = org.apache.tomcat.util.net.jsse.JSSE13Support; should be: static final String JSSE13Factory = org.apache.tomcat.util.net.jsse.JSSE13Factory; since there is no JSSE13Support class. The code is unchanged in 5.5.17. Rather than correct this one line of code, I think it would make sense to completely remove the JSSE13* classes. This resolves the problems that I'm having with building on a non-Sun JDK. It would also seem that nobody is using this support since the problem has not been reported. Does Tomcat 5.5.17 still support running on a 1.3 JVM? Should I create a bug report for this problem and do you think it would be feasible to remove the broken 1.3 support?

Re: Can't build Tomcat 4: Help!?
Actually, I eventually was able to build it without downloading JSX; but there were several things I needed to do that didn't appear in the BUILDING.txt file: 1. I had to downloat jakarta-tomcat-connectors using svn, because it's not available any other way that I could find. To build version 4.1.24 of Tomcat, I used the TOMCAT_4_1_25 tag (there was no 4.1.24 tag for the connectors). I also built Tomcat 4.1.31, but I found that the TOMCAT_4_1_31 tagged version of the connectors didn't work, though I found that the 4_1_25 did. Go figure. 2. I had to download jakarta-tomcat-jasper, which the BUILD.txt doesn't say anything about. 3. I had to make a jakarta-tomcat-connectors directory both at the same level of the directory tree as jakarta-tomcat, and one as a subdirectory in jakarta-tomcat. 4. I had to use the *exact* versions of the various commons packages that were specified in the sample build.properties file, despite the version xxx or later verbiage. Later versions simply wouldn't work. 5. For 4.1.31, I needed to download another package (commons-modeler-1.1) that isn't mentioned in BUILD.txt, but that shows up in the sample build.properties file for this Tomcat version. If you're so inclined, you might want to note some or all of the above things in the BUILD.txt file, to make things easier for others in the future. Chris Mark Thomas wrote: R.

Joe Bohn wrote: IIUC, this code in JSSEImplementation: static final String JSSE13Factory = org.apache.tomcat.util.net.jsse.JSSE13Support; should be: static final String JSSE13Factory = org.apache.tomcat.util.net.jsse.JSSE13Factory; since there is no JSSE13Support class. Rather than correct this one line of code, I think it would make sense to completely remove the JSSE13* classes. This resolves the problems that I'm having with building on a non-Sun JDK. It would also seem that nobody is using this support since the problem has not been reported. There are no references to the static String JSSE13Factory in the code base so it actually doesn't matter about the typo. This is no-one has complained - it isn't actually broken. Does Tomcat 5.5.17 still support running on a 1.3 JVM? Tomcat 5 requires 1.4+ but the connectors (of which this class is a part) are used by both TC4 and TC3. The code needs to stay. Should I create a bug report for this problem and do you think it would be feasible to remove the broken 1.3 support? No need. I've corrected it in SVN just in case someone makes use of it in some custom code - unlikely I know.

To build version 4.1.24 of Tomcat, I used the TOMCAT_4_1_25 tag (there was no 4.1.24 tag for the connectors). That's not good. I'll go take a look. I also built Tomcat 4.1.31, but I found that the TOMCAT_4_1_31 tagged version of the connectors didn't work, though I found that the 4_1_25 did. Go figure. This has certainly worked for me in the past. 2. I had to download jakarta-tomcat-jasper, which the BUILD.txt doesn't say anything about. The 4.1.32 source release will fix this. It will wrap up all the necessary sources into a single zip. 3. I had to make a jakarta-tomcat-connectors directory both at the same level of the directory tree as jakarta-tomcat, and one as a subdirectory in jakarta-tomcat. Sounds like dodgy default values in the build script. There have been issues in the past that I believe I have fixed for 4.1.32. Basically, with the 4.1.32 source distro, assuming you have all the libs, a simple ant build from the root of the source directory should be all the is required. 4. I had to use the *exact* versions of the various commons packages that were specified in the sample build.properties file, despite the version xxx or later verbiage. Later versions simply wouldn't work. That is really odd. What were the errors? SVN trunk builds quite happily with all the latest versions. The struts upgrade was a PITA but the rest were pretty painless. 5. For 4.1.31, I needed to download another package (commons-modeler-1.1) that isn't mentioned in BUILD.txt, but that shows up in the sample build.properties file for this Tomcat version. I'll add this one. If you're so inclined, you might want to note some or all of the above things in the BUILD.txt file, to make things easier for others in the future. I am so inclined - working on it now. Having all the source in a single zip (with the right structure) should make things easier. Thanks for the info.

HTH,
Mark
Thanks for your help.
Acording to the API, sendError from the *included servlet* will be ignored.
I think maybe this doesn't necessarily mean *Tomcat itself* can't do it. If
i'm trying to include a resource not existed after the response being
committed, the error message will be appended to the response, and sendError
be ignored.
Here's the snippet from
http://svn.apache.org/repos/asf/tomcat/container/tc5.5.x/catalina/src/share/org/apache/catalina/servlets/DefaultServlet.java
:
if (requestUri == null) {
requestUri = request.getRequestURI();
} else {
// We're included, and the response.sendError() below is going
// to be ignored by the resource that is including us.
// Therefore, the only way we can let the including resource
// know is by including warning message in response
response.getWriter().write(
sm.getString(defaultServlet.missingResource ,
requestUri));
}
response.sendError(HttpServletResponse.SC_NOT_FOUND,
requestUri);
If the response has already been committed, doing that will get a 404 error
page returned to the client, that means Tomcat set this status somewhere
else, or from some wrapper, but I failed to find it.
Any idea?

Re: Tomcat 5.5 / Apache 2 / Join (Tomcat-) Session with SSL-Session / Which mod should be used?
Darryl Miles [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Michael Decker wrote: My problem is, that the application session (set by cookie or url parameter) is not associated with the SSL session. And I hope, there is an easy way to that. I dont understand why you want to connect to two (under my definition of each explained above). Why I want that? If you've an application with session. So you can get the application information by spying (XSS, browser plugin etc.) or copying (URL with session ID). Because of that the idea was to join SSL session id and application session id, you can avoid that. Understood on what you are trying to do now. Maybe: http://java.sun.com/products/servlet/2.1/api/javax.servlet.ServletRequest.html and : 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. Before all HttpSession object usage you want to validate it, maybe a Servlet Filter would be a good way to handle this. http://java.sun.com/products/servlet/Filters.html The AJP protocol seamlessly conveys the SSL related information between apache and tomcat. Although apache+mod_ssl is the SSL endpoint, the web-app still have access to it just as-if you had setup SSL on tomcat directly. It is not normal to connect the SSL session in this way, as the HTTP protocol may (or may not) use the same SSL session details during the next request, the client may (or may not) support persistent connections. The SSL session cache is a performance optimization, not something an application gets to see or use directly. I'm not sure if I completely understand you: The SSL session (ID) can change between two requests? HTTP is a stateless protocol. So from a pure HTTP perspective, yes sure the ID can change between requests. In practice with featurefull browsers and a normal usage pattern linking them is probably safe you'll have to test with your userbase to be sure.

Re: Catching RequestDispatcher not found errors
Hi, Mark Thanks for your patient help. I have figured out the problem. It's not relevant to Tomcat. I tested my web application from NetBeans IDE with HTTP monitor enabled, NetBeans put a wrapper on the Tomcat's response object. I think that wrapper caused the problem. Thanks Best Regards Stephen
