RE: Can someone recommend a hardware device to Load Balance Tomc at
We use Foundry ServerIron to LB apache servers but it could also be used for Tomcat. I assume you want a HW based solution so you can get more options to distribute load than what the mod_jk's provide. If not, we've used mod_jk to balance multiple apache servers to multiple tomcat instances for a long time and am very happy. The changes to mod_jk to ease taking a server off-line comes very close to the concept of unbinding a server that you get with the foundry equipment.

One other idea, we have the Resource and ResourceParams in the
GlobalNamingResources and a ResourceLink in the application context. Using
4.1.24LE. We also had to put commons-dbcp and commons-pool into
commons/lib, these are not included in LE.

Re: Tomcat 3.3.1 - Sessions Migrating Between Users
Milt, I posted earlier (9/12) about a problem that we ran into with Apache/Tomcat having one user login and get another user's data. Look for Killing Apache Processes Connected to Tomcat via mod_jk (Ajp13) for a little background. In the logs we found the error where USER1 called a jsp via POST that validated and redirected to a different servlet (GET). The parameters on the GET URL were not for the person that just logged in but USER2 who had logged in earlier and was still on the system performing other requests.To say the least my world was rocked (in a bad way). They are SSL connections through different ISP's so I'm throwing out caching proxies. The USER1 didn't have jsessionid attached to his URL on this POST (we have cookies=false and encodeURL everywhere but it still happened). So now we added a hard coded ;jsessionid= on the first page to ensure it's there. I hadn't put too much thought into session hijacking.Now I am just hope and pray that I don't get another incident. I have asked over and over and have never had anyone respond or appear to have a similar problem. We are on Apache 1.3.26 w/ ajp13 and TC 4.0.4 and had been killing off apache processes that get stuck in a 'W' state.

I'll double-check it, but that's how it was originally written. Any other thoughts? I did say could be -- it is the most obvious thing that comes to mind. Similarly, it could be something wrong with those versions of Tomcat and/or mod_jk, but by the same token, if there were some such obvious/basic problem with it, you'd think it'd be pretty well known. But you might check the archives of this list to see if others have reported such problems with them. Is that the latest version of the 3.3 branch? If not, you could try to upgrade. In fact, if feasible, you might just upgrade to an entirely new version, and see if the problem persists. There's a 4.0 branch (up to 4.0.4) and a 4.1 (up to 4.1.11 already or soon). Both those versions implement the latest servlet/jsp specs (2.3/1.2) (3.2 and 3.3 implement 2.2/1.1). And the ajp12 protocol (I think that means version 1.2 of the AJP protocol) has been replaced by ajp13 (likewise, version 1.3 of the AJP protocol).

Killing Apache Processes Connected to Tomcat via mod_jk (Ajp13)
TC Users: I have a big production problem that I'm hoping someone in the group can address. Running Apache 1.3.26/mod_ssl with Tomcat 4.0.4 and mod_jk connector (4.0.4) on Sun Sparc servers. I have processes in apache which get stuck in a 'W' state for days while processing a servlet request through Tomcat.This is intermittent, although seem to be tied to database access over a WAN and availability (which I have zero control). These processes are killed with kill -3 pid. Now for the problem. We have had two reported occurrences in two days where one person logs in and gets a page back for someone else and one other a about month ago. I am trying to determine if killing the apache pids could leave the Tomcat Ajp socket open to return its content to the next person that connects.Besides having cache-control and pragma statements, all tranmission is via SSL upon hitting the login page so I'm betting against any external cache. If someone knows the ins and outs of the Ajp13 connector and tomcat who can address this I am eternally grateful.

Apache/Tomcat server-status Question
I have asked this question three times in the apache-users forum and not heard a response. I know this is a problem related more to Apache than Tomcat but I'm hoping someone who is running a similar configuration can help. I have a Sun Netra X1 Solaris 8 running Apache 1.3.22 w/ mod_ssl, mod_rewrite, mod_status, mod_jk with Tomcat 3.3. We are suddenly seeing processes that have long running R states (hours, days, ...) in server-status. If I do a server-status?notables I can see a reference to URL and IP but am not convinced this is the request that is hanging (the log files don't support what I'm seeing). The files see to be those that are not passed back to tomcat (ajp13, load balanced) for the web application such as .js, .gif and .jpg. None are zero length and they all have read permission. I also don't see anything via netstat that would indicate that there are other IP's connecting to a port but not sending anything across. from mod_jk.conf: JkMount /webstaff/*.jsp lbcon JkMount /webstaff/servlet/* lbcon Alias /webstaff /opt/jakarta-tomcat-3.3/webapps/webstaff Directory /opt/jakarta-tomcat-3.3/webapps/webstaff In looking at a custom logs w/ User-Agent, PID, IP and URL the problem references (if the logs are correct) seem to be 98 machines and usually customized (AOL, COX, MSN ) browsers. Am I alone in this problem? Could this in any way be hardware/os related? I have not seen this on another site we have that runs on Dell/RH 7.1 with Apache/Tomcat/JBoss, it has nowhere near the usage of the server that's encountering these issues.

RE: Apache w/ mod_jk and Tomcat 3.2.1 not handling URL rewriting
It sounds like apache is not configured to hand .jsp or /servlet requests
back to tomcat. From Tomcat 3.3 (sorry it's all I have around right now).
If you mistakenly encoded your gif/.js references you will need to do a
rewrite of the URL so apache can pass by it. I say it only because we did
it once and having mod_rewrite enabled on Apache was a god-send! Make sure
that you have the Include in your apache httpd.conf (e.g. Include
/opt/jakarta-tomcat-3.3/conf/auto/mod_jk.conf ).

;jsessionid= in them) give me a 404 error. Even when the browser has cookies

Apache/Tomcat/mod_jk growing TIME_WAIT counts
First, I am running an Apache 1.3.22 with Tomcat 3.3 using shared mod_jk, mod_ssl and mod_rewrite on a Sun Netra X1 Solaris 8, JDK 1.3.1_02 with os and jvm recommended patches applied. I notice that I have a growing number of processes that are left in a w state according to server-status. I check using netstat and see that there are sockets hanging out in a TIME_WAIT state. These will hang out for who knows how long but I have some that are days old (when apache was last restarted). Is this a bad-client issue, configuration of apache issue, apache-tomcat-session issue or something else I'm not considering. I'm guessing it may be an Apache issue but since I monitor this forum and see lots of expertise on combined containers I thought I'd start here. Any advise or direction is greatly appreciated.

Cookie Spec Tomcat 3.2.3
A new vendor were evaluating to processes XML through our site (Telephony support via XML) now claims (indirectly) that Tomcat 3.2.3 has incorrectly implemented the specification for Cookies, more specifically in the use of the Path attribute. The container is throwning an exception when they call back to us with a cookie named Path, which is of-couse illegal. All we create is a Session object which in turn creates the Cookie with JSESSION and its associated attributes. After reading the IETF RFC2109 (two or three times) it also seems clear to me that the Path attribute is permitted to have quotes around it (Section 5.1 Examples uses them ) and that Tomcat is doing it right. They claim that browsers don't necessarily enforce the spec and that's why the browsers works against the rest of the site but the XML traffic from their site doesn't. I think this is a load of crap especially since everything broke after they updated their software and the app subsequently stopped working. I saw bug #231 related to a fix in 3.3 but related to high volume which we're not and the bug (#231) could not be reproduced. Will have my team try TC 3.3 on Moday but I don't think anything is going to change. So to the question, is there a governing body that has newer, more complete definition of the Cookie specification that I should have read, is Bug #231 really related to our problem, or is it time for a heart-to-heart with these guys. Thanks, John Moore

Resource References for DataSources
I have configured the sybase jdbc 2.0 driver to work with tomcat as a resource. Unfortunately, there is no true pooling (min, max, timeout) feature and I need to wrap it with a real pooler. The JBoss pooler works in other servlet containers but I can't figure out how to get it to work here. I have tried various combinations of DataSources, parameter names and values to no avail. I either get null or throw a tyrex exception (when type != javax.sql.DataSource). The JBossPooler impelements DataSource, Referenceable and ObjectFactory so I though I would be able to just plug it in. I saw one posting where a person loaded and registered the connections in their own servlet but that seems to defeat the purpose. server.xml !-- works but doesn't support min/max -- Resource name=jdbc/test auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/test parameter namedriverClassName/name valuecom.sybase.jdbc2.jdbc.SybDataSource/value /parameter parameter namedriverName/name valuejdbc:sybase:Tds:192.168.0.15:1498/telestaff/value /parameter parameter nameuser/name valuedba/value /parameter parameter namepassword/name valuesql/value /parameter /ResourceParams !-- doesn't work (returns null on lookup) -- Resource name=jdbc/webdemo auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/webdemo parameter namedriverClassName/name valueorg.jboss.pool.jdbc.JDBCPoolDataSource/value /parameter parameter namepoolName/name valuejdbc/webdemo/value /parameter parameter nameJDBCURL/name valuejdbc:sybase:Tds:192.168.1.11:1498/telestaff/value /parameter parameter nameJDBCUser/name valuedba/value /parameter parameter nameJDBCPassword/name valuesql/value /parameter parameter nameminSize/name value1/value /parameter parameter namemaxSize/name value2/value /parameter /ResourceParams web.xml resource-ref res-ref-namejdbc/test/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref resource-ref res-ref-namejdbc/webdemo/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref When I do a ctx.lookup I see a ResourceRef but when I to a ctx.lookup I get a null. -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
