TC 3.3 -- user authorization not working correctly.
There seems to be some persistance of user authorization settings beyond Tomcat's global-users.xml and auth-users.xml file, and Tomcat startup and shutdown. I can't seem to get the authorization to work in a rational manner. I am only doing the simplest kind of authorization with roles and a user. What I have works but if I want to limit one user to one role that is in turn only used in one web.xml, it just won't do it. Why?? I think Tomcat is the server-side equivalent of Netscape browsers -- a time sink to be avoided. However, I am relatively stuck with it now, and would really appreciate any magic tips anyone might have out there. Also, if anyone has any workarounds to keep Tomcat from throwing an error when talking to N6/7/Moz over ssl, that would be appreciated. (My favorite situation was with Tomcat 3.2.4, which would completely crash into a memory leak when hit with N6/7/Moz). When the two team up, they're really great!

TC 3.3.1 authentication roles - what is going on?
It seems that to get good authentication whilst tying one role to one web app (so only one designated user can use a given designated webapp), I must assign two roles to the designated user: an arbitary role, and a role of deployer, and omit or comment out the role of deployer in web.xml: auth-constraint role-name dentalExpert0 /role-name !-- role-name deployer /role-name -- /auth-constraint In this case, the user Dr. Alan H is assigned to be a deployer. Authentication does not work well without this. I tried creating a dummy deployer, paired with dentalExpert0, but that did not work (it's commented out below). At least now, however, I can get good 1-1 authentication. I am running across two browser frames, and because document.domain assignments do not seem to mollify the furiously buggy Tomcat, I have had to submit to requiring the user to log-in twice, once for each frame. That is, until I change web servers.

Re: Mozilla crashes Tomcat.
Yes, you are right, excuse me for not supplying the basic info of several systems I am using. I'm using: tomcat 3.2 standalone - yes. Java SDK 1.4 (includes JSSE) Sun's JVM standard with SDK 1.4 The problem happens on Win2K and also on Linux RedHat 8.0 (Contains latest OpenSSL). I have by now done a fair bit of testing on this, all in the SSL mode. The application is stable when accessed by IE 5.5. When using Mozilla 1.1, however, the Tomcat Java process is inevitably thrown into a memory-allocating behavior (moving by about 10MB every 10 seconds) that continues until crash of the Tomcat Java process. Sometimes this behavior is invoked simply by logging in under Mozilla (SSL), and sometimes it requires an access or two from Mozilla. A tell-tale sign from Mozilla that the memory allocating behavior has been invoked is that a browser alert pops up saying document contains no data. I can run the very same accesses, using the very same front-end, from IE 5.5 with apparently no problem, and the behavior of the servlet is exactly the same for both browsers. I know that Mozilla uses a rather non-sensical security system whereby a site is deemed insecure if a window frame it contains is written to by JavaScript code from the original secured site. IE, of course, does not do this. Maybe there is some unfortunate interaction here with Tomcat? For it seems that something in Moz's headers must be confusing Tomcat. In any case, upgrading to 3.3 is not a bad idea. I am about at the end of my rope with this bug. I would go to 4.0 but want to stay as far away from the bleeding edge as reasonable and hope to avoid the changing of my configuration files that moving to 4.0 would necessitate. I really hope someone out there has some ideas. It is all too familiar a situation to me to have a Netscape product involved in just burning up days of my time. - CB Ralph Einfeldt wrote: Maybe you should provide the answer to following questions: - Do you run tomcat stand alone ? - If yes which JSSE do you use ? - Which jvm do you use ? - On which operating system ? Maybe you should try to profile tomcat with a tool like OptimizeIt to see if it is tomcat or the underlying ssl implementation that has the leak. BTW: tc 3.2 is quite outdated.

SSL request Mozilla browser causes memory leak on Tomcat 3.2.1
In repeated, side by side trials doing https requests (ssl), there is no problem and behavior is normal with requests from Internet Explorer 5.5 (memory allocation stays at about 22 megabytes), but Mozilla 1.0 seems to send some kind of request that causes Tomcat to just go on allocating memory until there is a mere 4 megabytes of memory left on my web server (Tomcat at this point is using about 82 megabytes of memory). Fun and more fun with Netscape products! ( -- as if web programmers haven't had enough already). The allocation goes up about two megabytes every 8 seconds. I wonder if it could be taken care of by more memory, or if the memory allocation would just go on. Any ideas? Why should a properly behaving server do this? I am running with default configurations. I hope someone can point me in the right direction. - CB -- . . . / This Cabinet is formd of Gold / And Pearl Crystal shining bright And within it opens into a World / . . .

I think in that case you would have to set a Timeout on the connection.
You might want to test the connection upon context startup and if the

saying that the app is temporarily unavailable.
Not sure what else you can do? Anyone?

The problem we are seeing with the hung connections, however, occurs
before any SQLException has been thrown, anywhere in the servlet

startup is made to a server which is unavailable, every other
connection will wait until that first connection times out (and then
throws its SQLException).

Can anyone tell me what the following error messages from tomcat.log might imply is wrong with my web application or dev environment? 2002-07-13 22:25:46 - Ctx( ): 400 R( /) null 2002-07-13 22:25:46 - Ctx( ): IOException in: R( /) error while writing to socket 2002-07-13 22:25:46 - Ctx( ): IllegalStateException in: R( /) Current state = FLUSHED, new state = CODING The whole log from startup of Tomcat is below. I am running a servlet under ssl that accepts a form value from a web page (http form) and performs a corresponding database query and returns the results to the client. It was working fine, and the only thing that changed I believe is that my laptop went into auto-shutdown mode once when it was running from its battery. Other servlets work fine.

Servlet dying silently under ssl.
Running tomcat 3.2 on Win2K with MySql. Use Cygwin and Emacs dev tools. I have a simple servlet running under ssl (public-private key) that is dying silently and unexpectedly. It was working flawlessly and then stopped working without there being any change anywhere on my entire machine that I would notice as something that would cause the servlet to die silently (can't get any logging). I don't know where to look next for the problem and hope for some suggestions. Prior to my latest reboot, I couldn't even 'tail' my tomcat.log. At that time when I ran this very simple servlet that was just working recently, tomcat.log became 416 Kb and wouldn't 'tail'. The servlet accepts a 'post'-method http form submission, and other servlets that do the same but not under ssl still run fine. I can get no 'servlet.log''s from the servlet that is dying. Two reboots ago, tomcat.log was also huge and showed what appeared to be low-level i/o errors from running the dying servlet. The symptoms on the client are that after http form submission the page just flashes (refreshes) and resets itself, with no server error message. The only defining change from when the dying servlet used to work that I can see is that the machine (a laptop running Win2K) shut itself down when on battery -- perhaps it ran low on juice. But all else works fine and since then I've shutdown and rebooted three times, to no avail. web.xml and the simple servlet in question are below, as well as a relevant section from servlet.xml, and the tomcat.log and servlet.log from my latest reboot and attempt. Any clues? servlet.log --- 2002-07-11 22:07:54 - path=/examples :jsp: init 2002-07-11 22:07:54 - path=/dynasurv :jsp: init 2002-07-11 22:07:54 - path=/admin :jsp: init 2002-07-11 22:07:54 - path=/dynasurv.tar.gz :jsp: init 2002-07-11 22:07:54 - path=/dynasurv.zip :jsp: init 2002-07-11 22:07:54 - path=/olddynasurv.tar.gz :jsp: init 2002-07-11 22:07:55 - path= :jsp: init 2002-07-11 22:07:55 - path=/test :jsp: init tomcat.log --- 2002-07-11 22:07:45 - ContextManager: Adding context Ctx( /examples ) 2002-07-11 22:07:45 - Ctx( /dynasurv ): Set debug to 9 2002-07-11 22:07:45 - ContextManager: Adding context Ctx( /dynasurv ) 2002-07-11 22:07:45 - ContextManager: Adding context Ctx( /admin ) 2002-07-11 22:07:45 - ContextManager: Adding context Ctx( /dynasurv.tar.gz ) 2002-07-11 22:07:45 - ContextManager: Adding context Ctx( /dynasurv.zip ) 2002-07-11 22:07:45 - ContextManager: Adding context Ctx( /olddynasurv.tar.gz ) 2002-07-11 22:07:45 - ContextManager: Adding context Ctx( ) 2002-07-11 22:07:45 - ContextManager: Adding context Ctx( /test ) 2002-07-11 22:07:54 - Ctx( /dynasurv ): XmlReader - init /dynasurv webapps/dynasurv 2002-07-11 22:07:54 - Ctx( /dynasurv ): Reading C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv\WEB-INF\web.xml 2002-07-11 22:07:54 - Ctx( /dynasurv ): Loading -2147483646 jsp 2002-07-11 22:07:55 - PoolTcpConnector: Starting HttpConnectionHandler on 8080 2002-07-11 22:07:56 - PoolTcpConnector: Starting HttpConnectionHandler on 8443 2002-07-11 22:07:56 - PoolTcpConnector: Starting Ajp12ConnectionHandler on 8007 2002-07-11 22:21:22 - Ctx( /dynasurv ): Get real path /static/QueryTool/index.html C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv\static\QueryTool\index.html C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv 2002-07-11 22:26:06 - Ctx( /dynasurv ): Get real path /static/QueryTool/index.html C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv\static\QueryTool\index.html C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv 2002-07-11 22:26:13 - Ctx( /dynasurv ): Get real path /static/QueryTool/index.html C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv\static\QueryTool\index.html C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv 2002-07-11 22:26:17 - Ctx( /dynasurv ): Get real path /static/QueryTool/index.html C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv\static\QueryTool\index.html C:\Program Files\jakarta-tomcat-3.2.4\webapps\dynasurv From server.xml: --- Context path=/dynasurv docBase=webapps/dynasurv crossContext=false debug=9 reloadable=true /Context From web.xml: ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.2//EN http://java.sun.com/j2ee/dtds/web-app_2_2.dtd; web-app !-- Servlets: -- servlet servlet-name DynaForm /servlet-name servlet-class com.treelogic_swe.frameworks.dynaForm.DynaForm /servlet-class init-param param-name dbDriver /param-name param-value
