This is odd. After setting permgen to 128m with -XX:MaxPermSize=128m I'm
seeing it hang again. What's odd is that the PermGen space appears to be
totally used up at 26MB and not expanding, unless I'm reading it wrong.

Configuring different environment variables for different vhost context?
Hi, I want to deploy multiple version of an application (Hudson [1] in my case). Each running instance needs the environment variable HUDSON_HOME point to a different location. However I only manage to either specify either a HUDSON_HOME for all instances or none at all :-( In tomcat55/server.xml I added Host name=hudson-test.dev appBase=/var/lib/tomcat5.5/hudson-test/ in tomcat55/Catalina/hudson-test.dev/ROOT.xml I have Context docBase=/data/java/archives/hudson-1.322.war Environment name=HUDSON_HOME type=java.lang.String value=/data/java/hudson-test/ /Context However it does not pick up HUDSON_HOME and I end up Hudson creating and using /usr/share/tomcat5.5/.hudson/ instead. I was only able to add global HUDSON_HOME variable which would be the same for all Hudson deployments (either passed them in the shell when starting tomcat or in the tomcat55/context.xml file). I found http://forums.java.net/jive/thread.jspa?messageID=85039tstart=0 which suggest to do exactly would I did, but it doesn't pick it up from there. I directed my question to Hudson but was suggested it may be a TC configuration issue. Can someone point me into the right direction? thanks, - Markus [1] https://hudson.dev.java.net/ - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I think you're absolutely right; I'm sill new into all that Java/Tomcat
stuff.
I searched a bit in the Hudson sources and found the following:
// check JNDI for the home directory first
try {
InitialContext iniCtxt = new InitialContext();
Context env = (Context) iniCtxt.lookup(java:comp/env);
String value = (String) env.lookup(HUDSON_HOME);
if(value!=null value.trim().length()0)
return new File(value.trim());
// look at one more place. See issue #1314
value = (String) iniCtxt.lookup(HUDSON_HOME);
if(value!=null value.trim().length()0)
return new File(value.trim());
} catch (NamingException e) {
// ignore
}
Matching that with your comment about JNDI, I see a partial match here
:) However I lack the knowledge to understand what the context lookup to
java:comp/env really means in relation to HUDSON_HOME .
Am I still on the right track now with my environment entry
configuration from my ROOT.xml? I can imagine that I'm missing only a
small link now ...
thank you in advance,

Whenever a client browses to webapps found on / and /foo, the requests to /foo will get TWO cookies, and confusion may occur (I'm not sure what mod_jk will do in this situation... Rainer?). My advice is to avoid nesting webapp URL spaces. I accidentally did this for years until I discovered the problem when adding sessionid-passthrough to another webapp (where the session id couldn't be validated before being passed-through) and everything went crazy. When I separated the URL spaces, everything was fine.

It turns out that the SSO information is only propagated while all instances are running. If Instance-A fails, several users then log in to Instance-B, then Instance-A comes back up, all of the SSO information for the users that logged in during the downtime is not included in Instance-A so those users are forced to re-login once the load balancer sends them to that instance. I wrote a fix for it, which might be useful for you. However, it hasnt been fully tested and is designed to only share the SSO information at startup, not all Session information. If Tomcat doenst handle this case, then the fix I wrote should be easily extended to handle that. Basically, when an instance comes up it broadcasts a request for all known SSO information to the cluster. It then takes the first response it gets and continues processing as normal. Let me know if you dont find a proper solution to the problem and I will try to dig up that fix.

Not sure either :( Even if I looked at the code now, I wouldn't take it for granted, that the behaviour can't change. Actually I'm not even sure what the browser is supposed to send (the same cookie multiple times, or only the one with the longest path match). My advice is to avoid nesting webapp URL spaces. I accidentally did this for years until I discovered the problem when adding sessionid-passthrough to another webapp (where the session id couldn't be validated before being passed-through) and everything went crazy. When I separated the URL spaces, everything was fine.

Class loading question (with aspectj)
I read the document at
http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html and have a
question. What is the class loading order if the classes are located under
/WEB-INF/classes/ and /WEB-INF/lib/ respectively?
I have a aspectj class (.aj) located under /WEB-INF/classes/ and a Filter
(TapestryFilter) class located under /WEB-INF/lib/. Will the TapestryFilter
get loaded first and ignore aspectj class?
My scenario is :
My web application configure org.apache.tapestry5.services.TapestryFilter in
the web.xml to filter incoming request. Then an aspectj class will intercept
the execution of TapestryFilter.doFilter() method. The aspectj class looks
as below
pointcut intercept(): execution(*
org.apache.tapestry5.services.TapestryFilter.doFilter(..));
void around() : intercept(){
System.out.println( test ...);
logger.debug(...); // slf4j log configured correctly
}
So what I expect is, for instance, when a user access from the browser the
log/console will print the log message. This scenario works fine when I copy
and rename (also change web.xml to use that new filter) TapestryFilter to
WEB-INF/class folder. However, if I use the default TapestryFilter (packaged
as jar file under WEB-INF/lib), the aspectj message won't be shown in the
log. Looks like the aspectj class is completely ignored.
Is there any document/resource that tells more detail on how class loader
would work if classes are located under WEB-INF/class and WEB-INF/lib? Or
any place of the source code would be a good start point to look at?
I appreciate any suggestion.
Thank you very much.

Re: 100% usage and hanging on startup of Spring/Hibernate app in Tomcat 5.5 on Ubuntu 7
I noticed that you mention that you are using the community version of the Java runtime environment which i think is what you get when you do an apt-get. I have never honestly been able to use this version of the JVM successfully. I had a similar problem recently where i was running an application (That uses Hibernate) using this version of the JDK and was always getting memory exceptions. What i did was to download sun's version of the JDK and that seem to have solved the problem. Did you try to use the SUN's version of the JDK from the SUN website? It might be usefull to try the SUN's version just to rule out that the JDK version/release is not the problem.

I haven't looked that closely at the code, but was there enough worry that it would cause side effects to make it a compile time AND a configuration option? I would say no, the configuration option is there for the time when we start having the chunked encoding code in by default. You can also do easier debugging, if you can turn it off without switching the binaries. Of course as long as the two binares are separate, turning chunking on by default would have been the more natural choice.

If you change the date/time by more than the session expiration time then the sessions are all going to expire.

Re: mod jk - multiple applications, different server clusers, sticky sessions
On 02.09.2009 23:38, Jason Wright wrote: I've an interesting situation with our application clusters. I am running multiple applications for one of our websites. We don't share sessions between the different servers; we use sticky sessions instead. Session replication is difficult because of the large size of our users' sessions. We use applications A B. I would like application A to run on servers 1 and 2 and application B to run on servers 3 and 4. The user initially requests application A and receives a sticky session for server 1. Later, the user requests application B. Since the sticky session was set, server 1 is accessed, but application B is not found. If No. The stickyness doesn't magically track your clients. If the client sends a session information, and the session information contains a route tag (a suffix .nodeX, where nodeX is set by the jvmRoute attribute in server.xml), then mod_jk looks for a balancer member named nodeX. When/How does the client send session information? Either as a cookie named JSESSIONID, or via URL encoding ...;jsessionid=nodeX By default, application A with context name /myappA uses cookies and only sends cookies if the request goes to something in /myappA. So a request for application B with context /myappB doesn't include the cookie for A and the load balancer is free to distribute the request to any node. sticky_session_force is set, then another server is tried; however, the No, see above. No session info, then stickyness is never applied. If there were session info, then the force switch would work in the opposite way, namely if set to false, it will allow failover. Default is false. sticky session will still be set to server 1 and the application B may not use the same server. I've thought of 3 possible ways to solve this problem with a preference to the one I don't know how to do yet. Not sure what the (real) problem is, likely you want both apps to be reachable under the same server name. The first (my preference) is to be able to use multiple sticky sessions, one for each application. This might involve multiple copies of modjk loaded by tomcat with multiple workers.properties files, or something like that. I would have no idea of how to do this. Does anyone know how to do this? No, this works out of the box. I assume there is no relation between the two apps A and B. Configute two lb workers, like lbA and lbB. One has member node1 and node 2, the other node3 and node4. Set the jvmRoute in server.xml of the four nodes to these names respectively. Finally add a JkMount /myappA|/* lbA JkMount /myappB|/* lbB That should be all that's needed. When testing, check the session cookies in order to understand what's going on. There are lots of Firefox plugins to look at cookies comfortably, like e.g. FireCookie. FireBug is also nice. The second way of solving this problem is to use multiple copies of Tomcat bound to different IP addresses with different configuration files. This solution would be seen as subdomains to the user. The third way of solving this problem is to use multiple copies of Tomcat bound to different ports (same IP address) with different configuration files. This solution would have the same domain, but different port numbers. I'm pretty sure that the second and third solutions would work, but I'm not sure about the first solution. I've searched extensively and haven't found anyone with the same problem. Has anyone on this list been in this situation or know the best way to solve this problem?

Re: Apache Tomcat ICD-10 compliance
2009/9/2 Mokri, Rhonda R rhonda.mo...@promedica.org Please indicate if there is a document that references Apache Tomcat icd-10 support as my searches of the Tomcat FAQ and Tomcat related websites have not produced any hits. My US based employer is a health care based organization that requires that we research every application to determine if there is a roadmap to support the migration to icd-10 by 2013. My initial response to my employer that there is a low likelihood of any issue with Tomcat and icd-10 was rejected as not being sufficiently 'official'. Thank you. I presume your employer has made similar searches of the Microsoft, Sun etc. sites, and has obtained documentary proof that Windows, Java, Microsoft Office etc. will be ICD-10 compliant by 2013? As an unofficial comment (I'm not an ASF committer, merely someone who's used Tomcat and has dealt with a number of medical applications), I'm not aware of anything in any version of Apache Tomcat or its connectors that is specific to any clinical coding system, and therefore I would not expect any Tomcat-related issues running a web application in Tomcat that used ICD-9, ICD-10, ICD-O, SNOMED-CT, SNOMED-RT, Read4, Read5, scans of handwritten documents or any other way of encoding clinical information. As Mark says, the issues will be in the applications, not in the containers that run them. - Peter -- Peter Crowther, Director, Melandra Limited

On Thu, Sep 3, 2009 at 9:56 AM, Shaun Senecal ssenecal.w...@gmail.com wrote: We had a similar problem with Tomcat 6 using clustering. It turns out that the SSO information is only propagated while all instances are running. If Instance-A fails, several users then log in to Instance-B, then Instance-A comes back up, all of the SSO information for the users that logged in during the downtime is not included in Instance-A so those users are forced to re-login once the load balancer sends them to that instance. I wrote a fix for it, which might be useful for you. However, it hasnt been fully tested and is designed to only share the SSO information at startup, not all Session information. If Tomcat doenst handle this case, then the fix I wrote should be easily extended to handle that. Basically, when an instance comes up it broadcasts a request for all known SSO information to the cluster. It then takes the first response it gets and continues processing as normal. Let me know if you dont find a proper solution to the problem and I will try to dig up that fix. My intention was to post it back to the group, but I got sidetracked once we (temporarily) stopped using clustering.

Re: /context not working -- mod_jk error: no match for /server-status
Rainer, I am not sending /server-status explicitly. The mod_jk log which I excerpted earlier shows the processing of server-status before any context is asked for, apparently when Tomcat starts up. The log continues to repeat these entries - apparently mod_jk is looping trying to satisfy this context and never does. I added JkMountCopy All but this had no effect.

how to unwrap a Request from RequestFacade
Hi, I am using tomcat 5.5 and just wanted to write a simple servlet to get some information using StandardManager such as activeSessions, expriedSessions, sessionCounter etc.. I am not that familiar with these classes. I noticed when the request comes into my servlet it comes as RequestFacade where the org.apache.catalina.connector.Request is wrapped inside it. I haven't figured out how to unwrap the Request object so that I can get the Context from which I can get the Manager (StandardManager) to access the information I need. Any help with a snippet of code to get the Request Object from RequestFacade will be appreciated. Thanks, -- Muthu

Re: Apache Tomcat ICD-10 compliance
Correct me if I'm wrong, but afaik ICD-10 is nothing but a code describing the hierarchy-structure of disorders like asthma, hayfever, cancer etc issued by the WHO. I do not see how Tomcat or any other web- / application-server should support such a standard: It's the application (here: servlet or jsp) which has to be able to support your favourite ICD-code. Therefore, ask the provider of your software dealing with ICD-codes wether it's ICD-10 compliant or not.

Re: /context not working -- mod_jk error: no match for /server-status
Rainer, Trying your /sample/ I get the same result. The log appears to respond to that try but the lines are similar to those I originally posted from mod_jk.log. It's as though every context request is translated into '/server- status'. the bracketed numbers are: [221:268597152] [debug] attempting to map URI '/server-status' from 5 maps. . . [221:268597152] [debug] attempting to map context URI '/sample/ *.=JBOSS1*' source JKMount . . all the entries are marked [debug]. 221 is process httpd with user _www.

Change redirect to SSL behavior?
The description of redirectPort for HTTP connector says: If this Connector is supporting non-SSL requests, and a request is received for which a matching security-constraint requires SSL transport, Catalina will automatically redirect the request to the port number specified here. The default is specified as port 443 which is of course the default SSL port. In Tomcat 3, there was a way to disable this behavior, i.e. if the end user connects to http://webapps and not use https for the given webapp, that was supported. If the user explicitly went to https://webapp they'd still get TlS/SSL as desired. I'm not seeing how to do this with Tomcat 6. If I take redirectPort out of the http connector, I still get the redirect, to the default 443 port. Having the ability to not get redirected to SSL/TLS avoids the users see issues with incorrect certificates, which unfortunately happens more often than I'd like. Is there a config or a workaround for this? Thanks, RP - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
