The fact that your app can connect successfully after the server restart,
suggests that you should have your app's context.xml (or whatever it is
called) not in the server.xml but in the correct location inside your app
directories. I seem to have read, the correct location being under the
META-INF directory and that Tomcat tries first to look for context in this
dir and then use that one under server.xml.
I hope expert user, will comfirm in one way or the other this understanding
of your problem.
As of TC 5.0 the prefered way of configuring a context (web application) is to
use a XML context fragment file. That file will either be placed in
${CATALINA_HOME}/conf/${HOSTNAME}/${CONTEXT_NAME}.xml, if you're deploying from
a directory or in ./META-INF/${CONTEXT_NAME}.xml, if it is a WAR file.
That way, deploying of an app can be free from editing the server.xml.
As for the original problem, that is NOT it. The fact that TC's restart picks
up everything suggests that the config is OK. Or at least relatively OK. I
think that TC will create a XML fragment for the app and it could be that
*that* fragment is interfering with the deployment process.
Since I can see nothing wrong with the config, I would advise the original
poster to go the correct route. Create the config fragment, pack it into your
WAR, clean up server.xml and try to deploy/undeploy/redeploy. It will have no
effect on TC 4.x, if you're warried that you might be forced to use it some
day, TC4 ignores that file (one question to the authoritative guys: will that
dir be accessable? - a potential security hole).
Nix.

RE: Tomcat - Hibernate
You want ENGINE_NAME in there too, i.e.:
${CATALINA_HOME}/conf/${ENGINE_NAME}/${HOSTNAME}/${CONTEXT_NAME}.xml
or, for example (spaces delineate variables above, don't really use them),
/usr/local/tomcat /conf /Catalina /localhost /ROOT.xml ==
http://localhost:8080/
/usr/local/tomcat /conf /Catalina /localhost /myapp.xml ==
http://localhost:8080/myapp

Re: Cannot create JDBC driver of class '' for connect URL 'null'
I've done several developments with MySQL and Tomcat. Never defined the datasource in the DefaultContext element so I can't speak to how that should work. The error is usually the result of a configuration element out of place between where the Resource element is declared and your java code. The Resource config looks good though. My advice is : - Move this Resource/ definition to your context's Context element in [tomcat_dir]conf/Catalina/localhost/[webapp_name_here].xml. If deploying in a .war file, the file should be named context.xml and placed in the META-INF directory of your .war file. - Make sure you have a resource-ref section in the web.xml file of your webapp. - This is pretty much a laundry list item, but make sure your mysql.jar file is in [tomcat_dir]/common/lib. The jar has to be there to be picked up by the tomcat container and instantiate a database pool. If you make these changes, restart tomcat to make sure it catches the new config. --David David McMinn wrote: Tomcat Server 5.5.15 - I searched for solutions and most mention a Context element in the server.xml.

Re: how to find out who is logging in?
This is doable, but you have to do it by yourself. If you want it on the client side (in John's browser) just let your webapp set a cookie. If you need it on the server side, your webapp has to perform it's own session management. If you have to write this solution by yourself you'll end up with approx. 100 lines of code. regards Leon On 3/2/06, epyonne [EMAIL PROTECTED] wrote: I don't know why my post during the day was not getting thru.

httpd.conf equivalent options in Tomcat's xml config files
We ran a vulnerability assessment (results follow below) and here are 2 issues that popped up, and the results suggest changing directives from the httpd.conf file, which of course we don't have. What Tomcat equivalent options in the XML config file(s) are needed to be set to fix these? The Mac OS X Finder creates a file called .DS_Store in each directory that it views. Some versions of OS X include system configuration information and file location information in these files. The .DS_Store files can be accessed from this server via a web request such as http://IP/.DS_Store. Service: Apache-Coyote/1.1 Bugtraq:3316 Configure your Apache server to block access to these files with the FileMatch feature of httpd.conf. Some distributions of Apache, especially in Red Hat 7.0, allow an attacker to probe a system for user names via requests for user home pages (e.g., http://host/~username). Service: Apache-Coyote/1.1 CVE:CAN-2001-1013 Bugtraq:3335 Disabling the UserDir directive in the Apache configuration file (httpd.conf) will prevent this, although it will also prevent users from providing their own web pages.

Re: ClassLoader IllegalStateException
ok, there could be plenty of things. but basically this is what is happening: one of your JDBC connections is being garbage collected. When this happens, it tries to close itself and in doing so, it needs to load a class. But the webapp is in a state where it has stopped (either been stopped, or reloaded) and throws an error. as mentioned earlier, more info on when this happens and in what circumstance.

How does BEA do that ? JRockit ? JFluid could be a way (when you're not profiling, the overhead is limited), but on production servers it's still not doable as enabling profiling would kill it. Of course, memory profiling could be low impact, and would be great already. On production, you can always use JDK jhat/jmap available in 1.5 and Mustang.

Re: double cluster in one server.xml?
I'm gonna let Peter Rossbach give you the final answer since he developed the simpleconfig concept. My guess is yes, if your hosts have webapps with the same names, they will most likely get mixed up. my suggestion to try would be Host name=test1.example.com appBase=webapps autoDeploy=false Context docBase=/home/ronald/tmp/HEAD/crm/web path= / Cluster className=org.apache.catalina.cluster.tcp.SimpleTcpCluster service.domain=vhost1/ /Host Host name=test2.example.com appBase=webapps autoDeploy=false Context docBase=/home/ronald/tmp/VERSIE_2_1/crm/web path= / Cluster className=org.apache.catalina.cluster.tcp.SimpleTcpCluster service.domain=vhost2/ /Host and that should stop the data from flowing between vhosts Filip Ronald Klop wrote: Hello, I have this in my server.xml.

JNDI Datasourse Best Practice
I'm happy to report that this newbie successfully set up a JNDI
Datasource insert self-satisfied cheer here.
I now have a question about the best way to create connections in my web
application. Previously, I used this class in other beans in order to
create and access connections:
public class dbConnection {
private static String url = jdbc:oracle:thin:@server:1521:sid;
private static String username = scott;
private static String password = tiger;
public boolean driverLoaded = false;
public synchronized Connection getConnection() throws SQLException {
Connection connection;
if (!driverLoaded) {
try {
Class.forName(oracle.jdbc.driver.OracleDriver).newInstance();
driverLoaded = true;
} catch (ClassNotFoundException ex) {
throw new SQLException(Can't find driver +
ex.getMessage());
} catch (Exception e) {
System.out.println(Something else happened in
dbConnection: + e.getMessage());
e.printStackTrace();
}
}
connection = DriverManager.getConnection(getUrl(),
getUsername(), getPassword());
return connection;
}
I'm planning using the same class, modified slightly, to serve up
connections from the Pool:
public class dbConnection {
private static String url = jdbc:oracle:thin:@server:1521:sid;
private static String username = scott;
private static String password = tiger;
public boolean driverLoaded = false;
public synchronized Connection getConnection() throws SQLException {
Connection connection;
Context initContext = new InitialContext();
Context envContext =
(Context)initContext.lookup(java:/comp/env);
DataSource ds =
(DataSource)envContext.lookup(jdbc/myoracle);
connection = ds.getConnection();
return connection;
}
Am I on the right track with this, or can I expect some grief? I'm
using the Shale framework with JavaServer Faces.
Thanks for your time.

DefaultContext problems
Hello all, I've been struggling to setup a datasource that is accessible from all my webapps. As I understand it, I define a Resource(/Server/GlobalNamingResources/Resource) and then a link it in a DefaultContext(/Server/Engine/Host/DefaultContext) like so: mailto:users@tomcat.apache.orgDefaultContext ResourceLink name=jdbc/apps global=jdbc/apps type=javax.sql.DataSource/ /DefaultContext The above doesn't work, but this does: Context path=/apply ResourceLink name=jdbc/apps global=jdbc/apps type=javax.sql.DataSource/ /Context I have nothing special in my servlet's web.xml file. Is there any reason this servlet wouldn't be using the declared default context? Any help other than, Don't use global resources, would be much appreciated.

Problems with extracting beans from a JavaServer Page

You see I want to extract the Bean from the page and use it in the code in my servlet. Now the servlet that loads up that page is different (it's called SearchServlet) to the one that deals with the button pressing (MatchServlet). SearchServlet passes it to the page as follows: GameBean gameBean = (GameBean) matches.get(0); request.setAttribute(gameBean, gameBean); address = /match.jsp; RequestDispatcher dispatcher = request.getRequestDispatcher(address); dispatcher.forward(request, response); Now in the MatchServlet servlet I have tried extracting the Bean using the code: GameBean gb = (GameBean) request.getAttribute(gameBean); But it is coming back as a null pointer error. I've also tried getting it using this code: HttpSession session = request.getSession(true); GameBean gb = (GameBean) session.getAttribute(gameBean); But again I'm getting a null pointer error. Can anyone help me and tell me how I can extract the gameBean from the page? Many thanks Mark Whitby [EMAIL PROTECTED]

mod_jk errors - are these normal?
If our setup was completely stable, and configured perfectly, should there be NO mod_jk errors ever? Or, are some errors part of normal operation? The system seems to work fine from a user's perspective, but we still occasionally get these: [Wed Mar 01 20:00:42 2006] [error] ajp_connection_tcp_get_message::jk_ajp_common.c (961): Can't receive the response message from tomcat, network problems or tomcat is down (10.0.0.9:8009), err=-113 [Wed Mar 01 20:00:42 2006] [error] ajp_get_reply::jk_ajp_common.c (1503): Tomcat is down or refused connection.

But, we also don't have much traffic right now. (Only about 700 visitors a day, with about 15 page views per visitor.) We've ran load tests, but the error message count doesn't seem to inrease by much if any. Are these error messages a normal part of mod_jk, or do they definitely indicate some sort of problem (like network issues)? We are using mod_jk 1.2.15, Apache 2.0.55 and Tomcat 5.5.15. For what it's worth, we have other completely separate system setups using mod_jk2, and they also all seem to get occasional ajp errors. This is our first setup using mod_jk, and we are assuming these errors are a bad thing. Thanks, -Michael __ Do You Yahoo!? Tired of spam? Yahoo!

RE: Tomcat - Hibernate
Hello,
I think we are getting very close I just need clarification on a few things.
First off I made the changes of taking out the Context setting in the
server.xml and created a context.xml file and put it into the META-INF
directory of my application. (Side note: I think this is a lot easier and
cleaner way of doing it)
I deployed my war file through Tomcat Manager with the context.xml file in
the META-INF directory and it would deploy but not connect to the database.
So, I also put the context.xml file in the following path:
${CATALINA_HOME}/conf/${ENGINE_NAME}/${HOSTNAME}/${CONTEXT_NAME}.xml
This would work great, but I still had to restart TC once I did this.
!--- Question 1 --
First Question: Is this correct to place the context.xml file in both
places when uploading with a WAR through Tomcat Manager?
I reviewed both these resources for more information but I didn't really
find what I was looking for.
http://tomcat.apache.org/tomcat-5.5-doc/deployer-howto.html
http://tomcat.apache.org/tomcat-5.5-doc/manager-howto.html
!--- End Question 1 --
What I would like to do is use Tomcat Manager to deploy, undeploy and
redeploy my apps. But remotely there is no way to upload the context.xml
file into the correct
${CATALINA_HOME}/conf/${ENGINE_NAME}/${HOSTNAME}/${CONTEXT_NAME}.xml path.
Below is an example of my context.xml file that I put into my META-INF. I
don't think you would have to change anything from the server.xml to this,
but I'm not sure.

You want ENGINE_NAME in there too, i.e.:

Hi,
I'm not an exper at all, but I try to put my 2 cents.
The fact that your app can connect successfully after the server restart,
suggests that you should have your app's context.xml (or whatever it is
called) not in the server.xml but in the correct location inside your app
directories. I seem to have read, the correct location being under the
META-INF directory and that Tomcat tries first to look for context in this
dir and then use that one under server.xml.
I hope expert user, will comfirm in one way or the other this
understanding
of your problem.
As of TC 5.0 the prefered way of configuring a context (web application) is
to
use a XML context fragment file. That file will either be placed in
${CATALINA_HOME}/conf/${HOSTNAME}/${CONTEXT_NAME}.xml, if you're deploying
from
a directory or in ./META-INF/${CONTEXT_NAME}.xml, if it is a WAR file.
That way, deploying of an app can be free from editing the server.xml.
As for the original problem, that is NOT it. The fact that TC's restart
picks
up everything suggests that the config is OK. Or at least relatively OK. I
think that TC will create a XML fragment for the app and it could be that
*that* fragment is interfering with the deployment process.
Since I can see nothing wrong with the config, I would advise the original
poster to go the correct route. Create the config fragment, pack it into
your
WAR, clean up server.xml and try to deploy/undeploy/redeploy. It will have
no
effect on TC 4.x, if
Response already committed when redirecting from error page?
Hi all, I'm using Apache 2.something, mod_jk and Tomcat 5.5.15. mod_jk sends all requests to Tomcat, so Tomcat needs to handle requests for nonexistent paths. Our application handles requests to more than one hostname, and the error response depends on the host to which the request was sent. OK, just one more wrinkle: one of the error responses should be a redirect. That is, http://somehost.com/nosuchpath should return an error page served by Tomcat, but http://otherhost.com/nosuchpath should redirect to http://elsewhere.com/404. Right now this is implemented thus: - error-page in web.xml goes to /errorpage - /errorpage is mapped to a servlet - the servlet inspects the server name; if the server is somehost.com the servlet forwards to somehosterror.jsp; if the server is otherhost.com the servlet forwards to otherhosterror.jsp. - The somehosterror.jsp part works fine, so enough about that. - Right now otherhosterror.jsp does a jsp:import of http://elsewhere.com/404. This works, but (since it's not a redirect) the user still sees nosuchpath in their browser. I'd prefer to do a redirect in the servlet. But if I do that, although the redirect works, I get Mar 2, 2006 2:15:47 PM org.apache.jk.core.MsgContext action INFO: Response already committed Same deal if otherhosterror.jsp does a c:redirect. As far as I can tell nothing here should be writing much output, much less committing it. So, why does this happen, and is it a problem? I hate to deploy something that spews mysterious log messages, especially if they mean the something might not always work or there's a resource leak or whatever. Thanks, -- David C.

Optimizing tomcat
Hello, I have the following setup. Java jdk 1.4.2 tomcat 5.0.19 Apache 2.0 mod_jk 2.0 ok there are 3 instances of tomcat and one of them with 4 webapps contexts. and 3 large applications that are used a lot. And I do some preloading of some data from database into objects at start up... About every week or so I get out of memory errors... Some of them are due to Java advanace imageing API. Its a little buggy but also sometimes because of tomcat needing more memory. and I am fixing some of my own apps bugs... So my questions: 1. I experimented with setting JVM memory options larger but I am not sure what's a good amount for each of the tomcats? 256MB.. 512MB...?? I only have 1GB of RAM and 2GB of swap and the machine has 2 Xeon and runs Redhat. 2. based on what should I make changes to these settings? or should just take the defaults? maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false acceptCount=100 3. If I upgrade JDK and tomcat would that improve things? I did see some bugs related to JDK 1.4.2 but 1.5 could have some other things too :) 4. I don't use jsp and infact I could even run things on Jserv so what tomcat version is faster and needs less memory?

This is our first setup using mod_jk, and we are assuming these errors are a bad thing. I always had those errors. I did anything i could do - change timeouts, change backlog, change this, change that - whatever - these errors remain. Just make sure, that the tomcat allows as much or more ajp-connctions, than there will be apache-processes/threads. I think the programmers have given up on solving this - whatever the problem is. AFAIK, mod_jk prints that error-messages to the log and then tries another connect which usually works. Actually i hear the developers say: this is not a problem - or something like that.

RE: Tomcat - Hibernate
I'm jumping in the middle here so forgive me if this has already been
covered.
If you notice that your context.xml is not being deployed from your own
META-INF directory, try putting the following in your server.xml :
Host name=localhost debug=0 appBase=webapps
unpackWARs=true autoDeploy=false deployOnStartup=true
xmlValidation=false xmlNamespaceAware=false deployXML=true
The deployXML=true is the important part. I'm not certain if that
defaults to false or not.
When I have the above and my context.xml in the META-INF, then tomcat
creates the mywebappname.xml within the conf/Catalina/blah blah/
directory.
Hope this helps.
