[RESULT][VOTE] Tomcat 5.5.12 is stable
Hi, The 5.5.12 stability vote is now over, and the release is stable. The following votes were cast for stable: Jeanfrancois Arcand Allistair Crossley Henri Gomez Jim Jagielski (not sure if this one is binding in the strictest sense of the word) Remy Maucherat Peter Rossbach Yoav Shapira Mladen Turk There were no beta or alpha votes. I'll go update the web site. There have been no code changes since the alpha release, so if you already have the 5.5.12-alpha distribution you don't have to go download a new distro.

[ANN] Tomcat sources moved to Subversion
Hi, FYI, the Tomcat source code has been moved to Apache's Subversion (SVN) repository. The old CVS repositories are now locked down: they can still be used for checking out code, but no further work will be done in them. For details on how to work with SVN, please see http://www.apache.org/dev/version-control.html. Please note that we are still verifying some of the build scripts to make sure they work in the new structure.

[ANN] Apache Tomcat 5.5.12-alpha Released
23 September 2005 - Apache Tomcat 5.5.12-alpha Released The Apache Tomcat team is proud to announce the immediate availability of Tomcat 5.5.12-alpha. This version contains several bug fixes, including an import change to session attribute storage concurrency that is required by the upcoming Servlet Specification v2.5. In addition to these changes, this release is a significant milestone for two reasons: This release is the last one to be done using the CVS repository at Apache. The Tomcat team is moving to the Subversion (SVN) repository as part of the overall Apache initiative to do so. Access instructions for the SVN repository are available at http://www.apache.org/dev/version-control.html. The move is expected to be complete within the next week. This release is also likely the last one to use the Jakarta pages. As part of Tomcat's move to a top-level project (TLP) at Apache, we will be migrating our content to http://tomcat.apache.org, which is still under construction at this time. That site will have its own download pages and related information. We will keep the key jakarta URLs intact with redirection, but please keep an eye out and update your bookmarks to http://tomcat.apache.org as/when appropriate. As part of the TLP move, distribution names have changed from jakarta-tomcat-* to apache-tomcat-*, and similar minor branding changes will gradually become visible in the web site and documentation. We thank the Jakarta project for its support over the years, and we will continue collaborating on projects and issues of common interest.

Re: servlet mappings
Howdy,
It used to be that servlet mapping was straight-forward and now it seems to
be obfuscated. For example I want the url
They haven't really changed in a long long time ;)
myhostip:myport/webappname/Form
This used to work and now it doesn't; Why !
!-- servlet-mapping
servlet-nameAeFormServlet/servlet-name
url-pattern*/Form/url-pattern
/servlet-mapping
--
I doubt this used to work: review the servlet spec section on servlet
request matching to see. Instead, have
url-pattern/Form/url-pattern
and that's it.
* in a url-pattern doesn't always mean the same as anything, especially
in the regular expression since of the word, because * doesn't match the
empty string. So */Form is not matched on a request to /Form. (All of
these are of course relative to your context base).
Set debug=99 for the context and/or connector in server.xml to see the
exact steps it is performing to match a servlet to incoming requests.

RE: running tomcat from CD
Howdy, Note, however, that all FileLoggers have a configurable directory. The workDir for host and context is configurable as well. The system.out/system.err destination is set to $CATALINA_HOME/logs/catalina.out in $CATALINA_HOME/bin/catalina.sh and can be changed at will. So a more accurate answer might be: - You need to modify the above in your server.xml and catalina.sh before burning your copy of tomcat to CD - Whatever directory you use for your logs and workDir (which is required by the servlet spec, as I said earlier) needs to be off the CD-ROM, but accessible and writeable.

RE: JNDI References To Tomcat 4.1
Howdy,
I believe he was referring to external access to tomcat's JNDI provider,
which is tricky. In-memory is easy and you're right a JDBC resource can
be configured (just like any other JNDI resource).
Of course, if tomcat's JNDI provider moves into its own jakarta-commons
component as we've been discussing, I bet you'd have standalone JNDI very
soon ;)

I have not seen reference to anything that suggests you can set up resources

a JNDI server (whatever the appropriate name for that is), as I've used that
with JMS/JBossMQ. AFAIK, the Tomcat JNDI setup stuff is just for processes
internal to Tomcat, but that is an educated guess, not a known fact :)

Subject: JNDI References To Tomcat 4.1
Greetings,
I am trying to create a standalone application that references a DBCP on
Tomcat. I'm not sure if I can do this; I've seem some articles that seem to
suggest that it can be done, but again, I'm not sure. I've read
http://www.mail-archive.com/[EMAIL PROTECTED]/msg08353.html.
I have set up in tomcat/conf/server.xml the following context info:

/DefaultContext
Note that I have not created any references in a web.xml, since I will not
be running an application, per se, from Tomcat. PERHAPS THIS IS WHERE MY
PROBLEM IS?
The client code I am using is not a servlet or a JSP; it's a simple piece of
code to see if I can communicate with the database pool on Tomcat as
configured above.
Hashtable env = new Hashtable();
env.put(
Context.INITIAL_CONTEXT_FACTORY,
org.apache.commons.dbcp.BasicDataSourceFactory
);
// *** THIS IS ANOTHER AREA WHERE I MAY BE WRONG! *** env.put(
Context.PROVIDER_URL,
http://localhost:8080;
);
try {
InitialContext initCtx = new InitialContext(env);
DataSource ds =
(DataSource)initCtx.lookup(java:comp/env/jdbc/test_db);
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery(SELECT * FROM tbl_test);
conn.close();
initCtx.close();
}
catch(NamingException e) {
fail(Naming exception thrown);
}
catch (SQLException e) {
fail(SQL Exception thrown);
}
I start Tomcat, assuming that the pool is set up. Then I use the client to
try to get an initial context from it. This throws a naming exception,
because it doesn't know how to get an initial context for
org.apache.commons.dbcp.BasicDataSourceFactory at http://localhost:8080.
My first question: can I do this?
My second question: If I can't do it like this, do I need to set up a JNDI
provider (like on JBoss) and set up the pooling there? My final question:
It feels as if my problem is simply setting up the PROVIDER_URL properly
so that it can get the context from Tomcat. I've done LDAP PROVIDER_URLs
before, but never one that gets a data source factory from a servlet
container. Can I use http over port 8080 to get the data source factory?
Is there a different mechanism for getting the factory from code that is not
residing within the servlet container? Can this even be done on Tomcat?
I appreciate any help that anyone can provide.
Cheers,
Jason

RE: Servlets/JSP crash, static content manager app OK
Howdy, See intermixed -- there are a lot of different questions here ;) This turned out to be the case, but for a funky reason. By using the JDBC drivers are a frequent cause for this. Another is JMS clients. It turns out that the SCSI backplane was the real problem and had to be replaced. Since getting this server back up was the main priority, I didn't snip Good piece of debugging there ;) Those can be a pain. Connection. I have since re-coded our ConnectionPool so that it abandons the Connection creation thread after 5 seconds (i.e. Thread.join(5000)). There It's interesting to hear this in light of the currently raging discussion among the DBCP developers on whether DBCP should support abandoning connections after a certain timeout. See the DBCP messages from the past couple of days on the jakarta-commons-dev mailing list for more details. Turn on debug=99 in server.xml (wherever you see debug=0). Same thing for the servlets defined in $CATALINA_HOME/conf/web.xml. Wowthat's a lot of logging on a production machine. It was very hard to find anything useful inside all the clutter, but by selective use of debug=99 in certain containers it was at least manageable. Yup, that's a ton. In the presence of a hard to reproduce problem, I prefer to start with overkill and then turn things off as I narrow down / rule out possible causes. It's a subjective thing ;) No security manager. I removed all the tomcat webapps besides manager and it didn't make a difference. My real question is why does this runaway thread crash almost everything in Tomcat? It doesn't seem to kill a lot of It's a JVM effect. It's not specific to tomcat, would likely happen in any container. The way it manifests itself might be particular to tomcat. resources. If a single execution thread (from a servlet or JSP) goes on infinitely, why does it screw up the whole servlet container? Or rather, part of the container since static pages and the manager app still worked fine even when things were bad. It didn't sound like the manager app was fine (it was hanging and you had to hit reload). And I don't recall but I thought the static pages were simply cached in your browser. Consider the case of a single thread somewhere in the JVM doing while(true); Nothing else matters, the JVM will be stuck, no matter how well-written the container is. On a related note, how do you know when you reach a load that exceeds the capacity of your server? I'm happy to set up load-balancing if need be, but I have no idea how to detect the need other than anecdotal slowness. You determine an acceptable response time for a page. You write a script that calls the page. You use a tool to run the script that lets you increase the number of concurrent requests. You run the script, measure response time, and when it drops below the acceptable range, you've reached your max capacity for the current configuration. Then you start tuning, e.g. maxProcessors for your connector.

Howdy, Commons-pool is a generic pooling framework. It's not specific (and in fact not that good, because of sync issues) for threads. Similarly, it's not specific to Processes. You would just use GenericObjectPool. If you want to synchronize things (or otherwise control thread-safety), you'd have to subclass/wrap GenericObjectPool yourself. In fact, come to think of it, SynchronizedGenericObjectPool may not be that bad an addition to commons-pool.

RE: loadOnStartup: Default Context Resources unavailable?
Howdy, Is there a place to put these definitions so that a new application deployed out of ant, for example, would be able to pick them up? GlobalNamingResources in the server.xml file. Am I missing an easy way to create the context with resources using ant? No, you're not AFAIK. I still like putting them in the Context rather than some global place, on the princinple that web appliations should be self-contained.

RE: ServletException
Howdy,
Perhaps the fact that in 4.0.x your JSPs were package-less and in 4.1.x they're
in org.apache.jsp? (Or vice versa, I can never remember).
Anyways, why are you using the tomcat-specific HttpRequestFacade instead of the
servlet specification's HttpServletRequest?

Subject: ServletException
I'm getting a ServletException when I try to access methods in a
HttpRequestFacade passed to one of my own classes. It's being casted
as a
HttpServletRequest in hopes to maintain portability. I'm able to
access
the methods fine from the JSP that passes the request variable, and the
reference is exactly the same when compared .. but for some reason
whenever I call it from my class it freaks out and causes the
ServletException which leads to the JasperException ..
For example:
jsp file:
[EMAIL PROTECTED] language=java import=my package.* % --
%
Cheese hi;
hi=new Cheese(request);
%
part of the class:
public class Cheese {
private HttpServletRequest _request;
public Cheese (HttpServletRequest req) {
System.out.println(uri: +req.getRequestURI());
}
}

Re: Tomcat's Ant Tasks
Howdy, I don't particularly feel like download Appfuse and contributing patches to it at the momeny -- no spare bandwidth ;( However, a few comments on your wiki page: - If you have something that's working and are happy with, there's no need to change to these ant tasks. - Reload is not pointless, you don't have to do a deploy anyways if you want to just reload an existing webapp (useful if you've changed, for example, configuration files). - The build.xml in the tomcat App Developer's guide contains task definitions for these tasks, so you didn't have to write your own ;) - I don't know why you're getting the JDBC driver null message, but I think I've seen that before: searching the tomcat-user archives might help. - I don't know why you're getting the IOException, and I don't think I've seen it before, so I'd be curious if it's particular to your app, e.g. if something in your app calls getRealPath() on startup or shutdown. The Ant tasks are just another way to do things: some people find it convenient. I use them some times, when I feel like it. I think Craig McClanahan once mentioned he uses them exclusively now, hardly ever actually restarting his tomcat instance.

Re: Tomcat Standalone and Virtual Hosting
Howdy, This partially depends on your OS. If you're on windows, you can just run tomcat on port 80. If you're on unix, port 80 is privileged and you need to: - Work around that, e.g. by using sudo or commons-launcher - Put an Apache front-end to serve static content on port 80, and connect it to tomcat for dynamic content. Either tomcat or apache by themselves support virtual hosting. For tomcat, you simply add more Host elements in server.xml. See the Host configuration reference in the tomcat docs.

Re: heap size config
Howdy, In Unix, java will make 512MB swap every time we make a System Runtime call. I don't think so: can you prove the above? Will this hurt the Tomcat preformnace? Lowering -Xms will only slightly degrade performance during the allocation phase. The effects are negligible during that phase and none afterwards. I read the article from Sun saying the -Xms and -Xmx should be the same. Is it always true? No. Almost nothing in the realm of performance tuning is always true. Setting -Xms equal to -Xmx is useful only if you're going to have a constant level memory usage more or less throughout the life of your JVM. If you start low and stay low until peak demand comes in, keeping -Xms low is more beneficial. GC and other operations are always faster on a smaller heap. Of course, nothing is more beneficial then having stress tests to run against different combinations of settings. That way you can see the actual effect on your system intead of relying on me or someone else's article. Yoav Shapira = Yoav Shapira [EMAIL PROTECTED] __ Do you Yahoo!? SBC Yahoo!

Re: FAQ? JDK 1.4 Logging in Tomcat - long and discussive
Howdy, You haven't missed something simple. In fact, I'd venture you've spent more time and thought (and reached better conclusions and solutions) that most people who've considered the problem. Ditch JDK 1.4 logging. Use log4j. Everything you want here can be done using log4j's Repository Selector: and it's even done for you for a webapp/context environment such as tomcat in Jacob Kjome's servlet context repository selector, currently available in the log4j sandbox and slated for inclusion in log4j 1.2.x. Yoav Shapira --- Tim Shaw [EMAIL PROTECTED] wrote: Feedback welcome - I've been working on this without much help, and others may well have more experience (which I'd like to benefit from too). I would love to use a better approach than that described here ... I needed to be able to log my various (multiple-context) web apps. As I couldn't get commons-logging to work with the JDK 1.4 logging, I went the 'direct' route ... and it turns out it wasn't the commons-logging that was the 'problem'. 'Logging' below refers to the JDK 1.4 java.util.logging facility ... Most of the stuff on the web just takes you through the api, and shows how easy it is to get logging to work. That's fine - it actually is fairly easy to program to. However ... Running Tomcat, I wanted multiple applications logging to different areas (files and/or db etc), and I started to run into difficult behaviour. The problem I had was to load my logging configurations into the LogManager - not the mechanism, but the practice. This is a singleton, within the scope of the bootstrap class loader. Consequently, the same object is shared across all contexts (and Tomcat itself). This means that resetting it and then loading an app-specific config file is not an option. Loading an app-specific properties file is an option (via getResourceAsStream), but that has the further restriction that each web-app has to have a distinct namespace (see below). The properties file is not very functional anyway - it specifies defaults for defaults! There is a 'config' option, which allows you to specify a Class for logging initialisation ... but this class has to be accessible from the bootstrap loader (common/lib, shared/lib ... nope! - it's gotta be in jre/lib/ext). Ideally, I would like to be able to supply an app-specific logging configuration file as part of the deployment of my web-app. Potentially, this could be done by loading a data-file from the context and interpreting it to provide the appropriate logging structure (loggers, handlers etc). But ... I have controller servlets in different contexts extending the same class from a 'utility' jar (implementing the Command pattern for Servlets). Most of the code is in the super-class (action class retrieval/activation etc). Following the logging examples, using the class name as the logging context, and making the log variable visible (protected) down to the sub-classes, I end up with multiple log files (logging expands the %u to provide a unique filename when it can't open[?] the file ... I don't even want to guess what it does when the %u isn't given). Additionally, I can't find a way to determine whether the logging had been initialised for a given context. This means that (IMHO) utility classes cannot log! I have ended up by extending the logging.properties mechanism, in the time-honoured way, by adding '.' separated properties for each logging-context : eg context.handler.level = INFO context.handler.class = com.xxx.app.DBHandler etc These are then added into the (system-wide) logging.properties file, and the Class which interprets them is specified in the config and has to be jar'd into the jre/lib/ext. Additionally, I have removed all logging-system stuff from my utility classes. I only get a Logger when I have a sufficiently unique path to guarantee no conflicts. This gives me the flexibility I need to log multiple apps in an appserver (tomcat) environment ... but I'm not very happy with it. It could be refactored to allow each context's Controller to load their own properties, and then interpret those (on my list of things to do), but this relies on calling a log-initialisation routine ... not something I want to do within 'client' JSP's (which live in another context). I have put JSP's into a different package (component separation - no problem), so the current setup allows me to specify that package as a root for which logging is enabled ... but this would not work without initialisation code unless I used the 'config' class approach. An additional restriction is still that I cannot log directly from the utility super-class. I have to create log variables at the concrete level. Summary : I don't think jdk 1.4 logging has come of age - it's nice and simple from the API POV ... but in real world usage it's lacking. Please tell me I've missed
Re: tomact shutdown issue
Howdy, There's always the obvious question: are you sure tomcat is running when you're shutting it down? The simplest cause for this error message is that tomcat is not running. A slightly less obvious reason is that tomcat could not start up properly, and could not open a listening socket on the shutdown port. Use netstat or an equivalent command to make sure tomcat is listening on the shutdown port when you're issuing the shutdown command.

Re: Best practice development directory layout for deploying exploded war
Howdy, My advice would be to follow the guide here: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/index.html Don't use the space under tomcat's webapps directories as a live development space. Only deploy built applications there. That means develop them elsewhere on your file system, in a version-controlled tree.

Re: rotating catalina.out
Howdy, OTOH - After the startup message - nothing really should be written to it without making an effort to do so. So only badly written code which uses System.out/err will be the victim. This is the incentive to use a real logging package. Allowing rotation allows reward of bad code. I agree in principal but reality is different. People writing a module often can't/don't require the user of the module (which is another software app) to install a logging package. System.out/System.err is the lower common denominator, and I think it's a reasonable thing to use if you don't know whether logging services will be available elsewhere. This why containers should provide their administrator with means to divert System.out/System.err into the container's logging mechanism. Tomcat does this with the swallowOutput feature. IMHO, swallowOutput should be true by default, so maybe I'll push for that in tomcat 5 ;) When swallowOutput is true, the output gets redirected to the appopriate tomcat logger, which rolls itself over nightly automatically.

Re: Migration to Tomcat from Weblogic 5.1
Howdy, If your web application is coded and deployd according to the servlet specification, you should just be able to drop it into tomcat without changes. The more Weblogic-specific stuff you have, the more painful your migration will be. For example, all com.bea or com.weblogic classes you use will need to be removed and the classes using them rewritten. If your web.xml has non-standard elements or elements in a non-standard order, you will need to correct that. If you rely on an invoker servlet, i.e. you have URLs like /servlet/com.yourcompany.yourservlet in your webapp, you will need to either comment in tomcat's invoker servlet or map your servlets in your web.xml file. Other than that, give it a shot and let us know if you run into any problems...

Re: Assessing Tomcat's State
Howdy, Note that the premise of your question is flawed without a precise definition of starting up and shutting down. Consider a tomcat instance with N webapps, each of which with one ServletContextListener. Tomcat on startup will send the contextInitialized event to each of these listeners. Each listener may do things that take a long time, and may or may not do them in the background. In the above scenario, when is the starting up state over and the started state entered? Is it when tomcat sends all N events, or when all N events are done processing? Similar scenarios can easily be construed for shutting down, and they are not limited to listeners as filters and servlets can all do varying amounts of processing on startup and shutdown. All of this may not matter in your scenario, so you may not have to worry about it at all ;) But they are important to keep in mind if you're trying to come up with some sort of general solution.

Re: Clear user session
Howdy,
Something else is modifying the session (adding/removing attributes or
otherwise modifying the backing collection of your session_var enumeration)
while you're iterating through it.
while(session_var.hasMoreElements())
{
String key=(String)session_var.nextElement();
You need to make the above code synchronized on the session. This may not be
as trivial as it sounds: for example, it might be impossible if your
environment is clustered.
Alternative options include doing this on session passivation or destruction
(probably the former), using the appopriate listener.
Why are you clearing all the attributes instead of a specific one?

Figuring out which Unix process is which
Hi, We run multiple instance of tomcat using the same JAVA_HOME, so when we run a ps command (Solaris 2.8) we see a bunch of java processes, but can't tell which one is which instance of tomcat. Does anyone have any ideas to help this problem? It's not possible for us to run the processes as different users, and the path is too long for the different CATALINA_OPTS to show through. I realize this may be more of a Unix question, but if anyone has suggestions, I'll be glad to hear them.

Re: Problems using own XML parser
Hi, JAXP is just a set of interfaces to isolate you from the parser implementation class. We use JAXP and have switched from Xerces to Crimson and back at runtime without restarting the server and without any problems. As to the performance of various parsers: you may find that what matters more than the parser implementation is your approach, e.g. SAX, DOM, XSLT, etc. Just a couple of days ago, Sun published a performance comparison of various parsers (including Crimson and Xerces. I don't remember if aelfred was included) and various parsing approaches. Check it out on the java.sun.com site (there's also a link from www.theserverside.com). Good luck, Yoav Shapira John Wadkin wrote: Rick, Simple question, here comes the complex answer :) I'm a student who's working for my Uni for a year.

The project is funded by the Higher Education Funding Council (HEFC - f-ki), so we don't have a lot of cash! Unlike America, education in the UK hasn't yet sold out to the big multinationals (Coca Cola day). This means that instead of using a proper server, I'm having to make do with a workstation - a Sun Ultra 10. I'm no expert on servers, loads, load balancing and all that, but I should imagine that performance will be a problem. In view of this, I'm keen to squeeze as much out of the server as I can. The person who actually wrote the servlet recommends using Aelfred because of it's speed, hence my asking about using a parser other than Xerces. Thanks to Charlie, I checked the bug database - didn't think it would be bug, and it isn't. The bug database mentioned postings on the list about XML parsers, which I've read. From what I can tell (it isn't too clear): 4.0.1 only works with xerces.jar in common/lib - no per-WebApp parser is permitted 4.0.4 will allow per-WebApp parsers so long as it implements something called JAXP - i.e. xerces Looks like the developers have been reading Microsoft's marketing strategy :) I might have it totally wrong - I don't fully understand all the stuff about parsers and classLoaders - nor should I!

I WANT System.exit(0) ;)
Hi, So tomcat4.0.2 remove the System.exit(0) call at the end of the Bootstrap class, and there are good reasons to not have it there (for embedded invocations of tomcat, etc.). I'm also aware of the possible harm of System.exit(0) and the use of SecurityManager to prevent that. Here's my situation, though: I use 3rd party code that I trust but cannot modify, and I think this code creates threads and does not interrupt/kill them appropriately. Therefore, when I shutdown tomcat, the tomcat process never dies. It stays resident in memory etc. This is not acceptable for us, so we can't use tomcat4.0.2. I know relying on System.exit(0) is not a good idea. Does anyone have other ideas, suggestions, etc on this issue?

Filter mapping question
Hi, I have a servlet and a filter I want to be run when that servlet is accessed. However, the servlet is never accessed directly via the browser. Rather, it's embedded in a frameset and launched using something like this: a href=javascript:void(0); onClick=thatframe.src='http://myhost/mycontext/myservlet'; return true; click here /a So in my web.xml, I have: filter filter-namemyFilter/filter-name filter-classmyFilterClass/filter-class /filter-name filter-mapping filter-namemyFilter/filter-name servlet-namemyServlet/servlet-name /filter-mapping servlet servlet-namemyServlet/servlet-name servlet-classmyServletClass/servlet-class /servlet The problem is, tomcat never calls doFilter() for my filter when that servlet is called. The filter gets initialized appropriately (I have logging comments on the filter's init(), doFilter(), destroy() methods). If I go to http://myhost/mycontext/myservlet myself, the filter does get called, so I know it has to do with the calling mechanism, filter-mapping, or something along these lines.

Re: Known Memory clean-up issues?
Howdy, Any harm in forcing garbage collection to run? You cannot force garbage collection to run, only suggest it to the JVM via methods like System.gc(). If you're having difficulty tracking down memory usage, try a profiler like OptimizeIt that has entire memory trees. In addition, you can use parameters like hprof and verbosegc on the java command line to assist you in monitoring garbage collection.

Re: Shutdown Tomcat
Howdy, My two cents... Solaris 2.6 on an Ultra 10, tomcat 4.0.1, takes about 20 seconds for complete startup, less than five seconds for complete shutdown (process gone and everything). My setup right now has 3 webapps, one of which spawns a couple of threads (but takes care to terminate them appropriately)... Yoav Steve Brunton wrote: Evan Swanson wrote: Yeah, I have been wondering the same thing. On unix is seems that you have to kill the process. Shutdown.bat and shutdown.sh do not seem to stop the Tomcat process. I am guessing they just log off all of the sessions 'gracefully' You then have to manually kill the process? I am not sure if this is a problem with tomcat or it is supposed to be that way. It seems to be the same effect when you use the manager application to shutdown tomcat so I am guessing that it was designed to work that way. I have been unable to find any doco on the subject. Does anybody know a better way of shutting down the server than killing the process? I've got Tomcat 4.0.1/JDK1.3.1_01 shutting down happily on Solaris x86 just spiffy like. It does seem to take it a while to spool everything down. Currently it's only loading about 10 servlets and if I tail the output log as the thing is shutting down I can see it hitting all the destroy() methods and shutting down JNDI, JDBC and LDAP connections. Make sure that all your servlets clean up after themselves and it should shutdown fine. -- Steve Brunton [EMAIL PROTECTED] Phone: 404-827-2756 Chief Engineer Enterprise SystemsOne CNN Center, Atlanta GA CNN Internet Technologies ICBM: 84W 23' 45 33N 45' 29 * I used to have a handle on life, but it broke. * -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
Re: set SessionID (PLEASE HELP)
Howdy, The sessionID is an internal identifier assigned and used by the web server (typically). Maybe you want to consider using your own session variable with a different name, that you can assign and control manually? It would be your responsibility to guarantee uniqueness, but that's usually not a big hassle, and the flexibility is worth it.

Re: getRemoteAddr() vs getRemoteHost()
Hi, My guess is you need to enable remote address lookups in your server.xml. Since they are expensive to log, they are usually turned off by default, and the behavior is to simply return the address rather than the host. Yoav Miao, Franco CAWS:EX wrote: When I put the following code in my Jsp, it comes up two identical remote IP addresses, instead of one remote IP and one remote host name. My computer has Internet IP and valid Internet DNS server. Any suggestion about that? Thanks! out.print( request.getRemoteAddr() ); out.print( request.getRemoteHost() ); Franco
Can't open InputStream to manager??
Hi there, I have a servlet that tries to do something like: URL url = new URL(http://manageruser:[EMAIL PROTECTED]:myport/manager/list;); URLConnection con = url.openConnection(); BufferedReader bin = new BufferedReader(new InputStreamReader(con.getInputStream); The third line throws an exception. The connection itself is fine, I can call stuff like con.getContentLength() and it works (correctly) without a problem. Is the manager app coded specifically to disallow opening stream to it? Has anyone else tried/encountered something like this? Thanks! Yoav Shapira Millennium Pharmaceuticals
Re: Chaning location of initial web page
Hi, You can always use HTML or JSP forwarding, along the lines of: html head meta http-equiv=REFRESH content=0; URL=/miiq/index.html /head /html Or something like html head titleJSP Forwarder/title /head body jsp:forward page=/miiq/index.html /body /html Good luck, Yoav Ryan Brown wrote: We are having a alot of trouble changing the location of the first page that displays on Tomcat 3.2.3 server. If i start the server and then point my browser to http://localhost:8080/ it brings up the following file: d:\jakarta-tomcat-3.2.3\webapps\root\index.html how do I change this so that it brings up an index.html in a different directory on my harddrive: d:\webdevelopment\miiq\index.html I have searched all of the documentation and the mailing list archive and I have only gotten more confused.

Re: Newbie: Tomcat EJBs
Hi, It's still there. For the adventurous, try the new JBoss2.4.1-Tomcat4.0 integrated download: http://prdownloads.sourceforge.net/jboss/JBoss-2.4.2_Tomcat-4.0.zip Otherwise, you can just go to jboss.org and download the latest release-quality thing, which is integrated with Tomcat 3.2.3 I believe.
