You choose which one you want to use based upon your needs and any company policies which might apply. Both support the same API (JSR 127). Try thinking of it this way. Both MyFaces and JSF RI offer you a library (jar) of methods which allow you to develop JSF format web pages. Each library offers the same standard set of capabilities - the JSR 127 API. Each library is written and supported by a different group. Both will run on Tomcat (or any other reasonable application server) since both are written using Java. To integrate either with Tomcat, you simply download the library, add it to your project's classpath, and then write JSF-specific web pages to take advantage of the JSF technology.

Re: Tomcat 5 slow, it's in production, please help!
Thanks for the advice. I will try your suggestions. I noticed that from the server status view of the tomcat manager, I saw some thread with the status 'S' has the time of '24685295'. Does it mean the thread has hang there for more than 6 hours (close to 7 hours)? --- Parsons Technical Services [EMAIL PROTECTED] wrote: I think that would be the direction I would take. If you need more proof: Sniff the connection to the server to confirm the lack of available connections. So far it is pointing in that direction. Another test you might do is create a connection from a known IP, close the browser and monitor the connection status. If it is hanging open then start digging. I think you may also be experiencing an issue of clickatosis. It occurs when the client doesn't think the page is responding quick enough and since more is better after 10 or 20 clicks they decide to wait or give up. Mean while for each click they cause a request which can bog things down. Wrapping this with the held connections you can get a scenario as such: Client hits site. No or slow response. Clicks again. Or several times. Often closes browser and tries over. This creates a new connection request. Snowballs from there. Think about this, do you really get over a 100k users in six hours? Or even 100k page requests? That's a lot of traffic. If the client machines abandons the connection before the server, then establishes a new one, it compound the problem. Find a way to have the OS let Apache handle the connection timeout and get it down to a reasonable time. Since you are inheriting this, there may be a reason that the connection timeout is set so high. If the original creator of this wanted the user to be able to sit on a page for a long time without losing the session and connection thus causing the user to have to re-authenticate. But then there is a trade off. which you are experiencing right now. Get the time down until the complaint about having to re-login get too high or until the connection speed delay is acceptable.

It seems that, at least in most cases, the main menu page after a login is loaded slow. After that other pages are loaded pretty quick. Does that mean once a connection is established, browser and server communication is ok. If that is the case, maybe I should look more at the connection timeout at the OS level (solaris 5.6) since I see a lot of TIME_WAIT at the machine using the 'netstat -n' command. --- Jeffrey [EMAIL PROTECTED] wrote: Please see the answer embedded below. --- Parsons Technical Services [EMAIL PROTECTED] wrote: 127421 over what period of time?

I am using Apache SSL for SSL connections. It is the original setup by someone else. Also what is the time out for the connection in Apache? Apache's Timeout value is 300.

To quote Mladen: You are probably using prefork mpm, so there is no way to control the number of connections to Tomcat in any way, trough mod_jk. You can limit it only by setting MaxClients in the httpd.conf to the maximum number desired. Because of pre-forking mechanism each child process will eventually establish a single connection to Tomcat, thus the number of connections will rise from StartServers to MaxClients. So there are two solutions for prefork. 1. Make maxThreads==MaxClients 2. Add connectionTimeout=2 to AJP connector.

RE: Tomcat 5 slow, it's in production, please help!
As a wild guess Browser drops the connection immediately without notice After 5 minutes, tomcat decides to drop the connection After 30 minutes or so, Solaris finally finishes dropping the connection.

Re: Tomcat 5 slow, it's in production, please help!
It seems that, at least in most cases, the main menu page after a login is loaded slow. After that other pages are loaded pretty quick. Does that mean once a connection is established, browser and server communication is ok. If that is the case, maybe I should look more at the connection timeout at the OS level (solaris 5.6) since I see a lot of TIME_WAIT at the machine using the 'netstat -n' command. --- Jeffrey [EMAIL PROTECTED] wrote: Please see the answer embedded below. --- Parsons Technical Services [EMAIL PROTECTED] wrote: 127421 over what period of time?

Re: Tomcat 5 slow, it's in production, please help!
I think that would be the direction I would take. If you need more proof: Sniff the connection to the server to confirm the lack of available connections. So far it is pointing in that direction. Another test you might do is create a connection from a known IP, close the browser and monitor the connection status. If it is hanging open then start digging. I think you may also be experiencing an issue of clickatosis. It occurs when the client doesn't think the page is responding quick enough and since more is better after 10 or 20 clicks they decide to wait or give up. Mean while for each click they cause a request which can bog things down. Wrapping this with the held connections you can get a scenario as such: Client hits site. No or slow response. Clicks again. Or several times. Often closes browser and tries over. This creates a new connection request. Snowballs from there. Think about this, do you really get over a 100k users in six hours? Or even 100k page requests? That's a lot of traffic. If the client machines abandons the connection before the server, then establishes a new one, it compound the problem. Find a way to have the OS let Apache handle the connection timeout and get it down to a reasonable time. Since you are inheriting this, there may be a reason that the connection timeout is set so high. If the original creator of this wanted the user to be able to sit on a page for a long time without losing the session and connection thus causing the user to have to re-authenticate. But then there is a trade off. which you are experiencing right now. Get the time down until the complaint about having to re-login get too high or until the connection speed delay is acceptable.

Yoo, Probably you already looked at it but : 1) Make sure not to use reloadable in context descriptions. 2) Start tomcat with optimal java parameters, concerning memory heap and stack 3) Make sure that connections to database are minimal, do requery if answer is always the same...

Re: Tomcat 5 slow, it's in production, please help!
What JK version do you use? To quote Mladen: You are probably using prefork mpm, so there is no way to control the number of connections to Tomcat in any way, trough mod_jk. You can limit it only by setting MaxClients in the httpd.conf to the maximum number desired. Because of pre-forking mechanism each child process will eventually establish a single connection to Tomcat, thus the number of connections will rise from StartServers to MaxClients. So there are two solutions for prefork. 1. Make maxThreads==MaxClients 2. Add connectionTimeout=2 to AJP connector.

RE: Tomcat 5 slow, it's in production, please help!
I think some of the problem is at the OS level You can set a session time at the tomcat level, but the default solaris TCP timeouts are hours long. I hope you used the ndd commands to set the TCP parameters for short web sessions. Also, Solaris 2.6 has a bad thread model and there are numerous patches required to run it with any recent Java 2 distributions. To use the 1.4.xxx JVM would require about a dozen patches. It would be way better to try to get Solaris 10 installed on this box -- It handles the ndd setting for you and is way faster on the same hardware.

simple deployment problem - please help
hi;
i have tomcat 5.5.9 running with jdk1.4.2
my application is configured in a context element in the server.xml and it is
deployed twice instead of once!!! (only one context is defined in the
server.xml)
i have no idea why.
if i remove the context element from the server.xml and prepare a myapp.xml
and put it in the conf\Catalina\localhost than it is deployed once but the path
element is ignored (per spec) and my application is a root application (should
start when invoking localhost:8080) so its not a good solution.
below is my server.xml and a view of tomcat console output. the server.xml is
really basic.
i hope someone can please guide me cause i am desperate here.
thanks in advance.

Re: DBCP Please Help Get Working Properly
Ok, define 'no results'. In reality, the naming import isn't the only
thing that changed. Your web.xml file *looks* like 2.3 spec from what I
can see and you are using JSP 2.x spec syntax in your jsp. If you want
the JSP 2.x spec features, you need to declare your web.xml file for
servlet 2.4 spec. This should be up at the top of your web.xml (pasted
from the specification for servlet 2.4):
?xml version=1.0 encoding=ISO-8859-1?
web-app xmlns=http://java.sun.com/xml/ns/j2ee;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
xsi:schemaLocation=http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd;
version=2.4
Then just put all your servlet-mappings, etc., ... after that. The
taglib declarations need to be inside a jsp-config element for the 2.4
spec web.xml file too. That's how I'm guessing you have a 2.3 spec
web.xml file. The full spec can be found at

This makes some sense, and I will try and make the changes. But this of course

container versions, jsp versions, possibly better ways to use then putting the

would like to connect in some class where I can call connections from. Does

Re: DBCP Please Help Get Working Properly
Well yes it does make a lot of sense, but is more a question answered by
design patterns. It's a little beyond the scope of Tomcat docs to
address issues like separation of roles. Both Struts and Spring
projects address issues like this with the Model-View-Controller (MVC)
pattern and there are innumerable books on the subject as well.
Specific to data access methods, Hibernate also addresses this issue.
As far as step by step docs, you are best off picking a framework,
getting a good book on it and go from there.
Hope this helps.

RE: DBCP Please Help Get Working Properly
Do you have anything in your Tomcat log files that might help? If not, you can
bump up the debug levels in server.xml and you might get some more info.
I also found that adding one of the two following listeners in my server.xml
helped me debug my DBCP problems (I don't remember which one I added, but it
should be obvious):
Listener
className=org.apache.catalina.mbeans.GlobalResourcesLifecycleListener
debug=9/
Listener
className=org.apache.catalina.core.NamingContextListener
debug=9/

Subject: DBCP Please Help Get Working Properly
Hello,
I am trying to use the DBCP features of Tomcat 5.5.7. I created a webapp named
testDB and put it under $CATALINA_HOME/webapps/testDB. Then I created a
testDB.xml file under $CATALINA_HOME/conf/Catalina/localhost/testDB.xml.
// here it is
Context path=/testDB docBase=testDB
debug=5 reloadable=true crossContext=true
Resource name=jdbc/testDB auth=Container type=javax.sql.DataSource
maxActive=100 maxIdle=30 maxWait=1
username=javauser password=javadude
driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/fritest?autoReconnect=true/
/Context
I have been following the notes from:
http://localhost/tomcat-docs/jndi-datasource-examples-howto.html
I made sure I completed the rest of the tasks.
WEB-INF has the two tag locations, and the resource ref.
eg:
taglib
taglib-uri/WEB-INF/sql.tld/taglib-uri
taglib-location/WEB-INF/sql.tld/taglib-location
/taglib
taglib
taglib-uri/WEB-INF/c.tld/taglib-uri
taglib-location/WEB-INF/c.tld/taglib-location
/taglib
resource-ref
descriptionDB Connection/description
res-ref-namejdbc/testDB/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
I finally hit my jsp page which is this:
%@ taglib uri=http://java.sun.com/jsp/jstl/sql; prefix=sql %
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
sql:query var=rs dataSource=jdbc/testDB
select id, foo, bar from testdata
/sql:query
html
head
titleDB Test/title
/head
body
h2Results/h2
c:forEach var=row items=${rs.rows}
Foo ${row.foo}br/
Bar ${row.bar}br/
/c:forEach
/body
/html
And I get no results:
Now I am pretty sure I have all configured. Because if I use a fallback (Tomcat
4.1) code piece I had, I get results using the same settings:
package foo;
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class DBTest {
String foo = Not Connected;
int bar = -1;
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception(Boom - No Context);
DataSource ds =
(DataSource)ctx.lookup(
java:comp/env/jdbc/testDB);
if (ds != null) {
Connection conn = ds.getConnection();
if(conn != null) {
foo = Got Connection +conn.toString();
Statement stmt = conn.createStatement();
ResultSet rst =
stmt.executeQuery(
select id, foo, bar from testdata);
while(rst.next()) {
System.out.println(next );
foo=rst.getString(2);
bar=rst.getInt(3);
}
conn.close();
}
}
}catch(Exception e) {
e.printStackTrace();
}
}
public String getFoo() { return foo; }
public int getBar() { return bar;}
}
And using the above class works all day.
The only difference I see is that the class using a naming import and the jsp
does not. Can anyone help.
Thanks,
Scott

So cool, I opened up the server.xml, but do not see any existing context or
host tags in it. Here is my server.xml file. Does anyone know where I put the

My apologies, we're using 5.0.x and I hadn't realized they went away. But maybe

Re: JDBC connection - Please help
Hi,
Looks like you are using the Tomcat Connection pool.
Refer to the attached Readme.txt file and verify that you have done these
steps.
I think it should solve your problem.
Have also attached the server.xml web.xml files which worked fine for us.
let me know whether ur problem gets solved by this.

Re: Fwd: JDBC connection - Please help
Deepak,
This '' and null error means that the Tomcat is not finding the JDBC
JNDI resource.
This is how to fix this on Tomcat 5.5:
Make sure that you have a Resource element properly configured in your
context.xml that is in $CATALINA_HOME/conf/ directory.
Resource name=jdbc/TestDB auth=Container type=javax.sql.DataSource
maxActive=100 maxIdle=30 maxWait=1
username=someuser password=somepassword driverClassName=your
driver
url=proper url for your db's jdbc conventions/
/Context
Make sure it is available to your web app, by setting the references in
your web.xml.

Developing a large project using Tomcat, please help me
Hi, we are developing a large java project using Tomcat. On the same project works several persons and the project counts serveral thousand of classes. The project has (in few words) three big places: - standard: the place in which are placed all the classes (not jar but classes) - patches: the places in which are places the bug-fixes of standard classes - work in progress: the place in which a developer develop his own modification to a standard class Each developer has its own Tomcat. Now, imagine that - in standard classes is there a class named: helpme.class - this class has been bug-fixed and in patches is there the same class - a developer is working on its own local copy of this class and he has places it in his own work-in-progress folder Is possible using Tomcat to manage a situation like that? In other word, If I develop using j2SE standard, to obtaint what i want, I simply set my CLASSPATH env variable in this way; set CLASSPATH=x:\MyWorkInProgress\classes;x:\AllPatches\classes;x:\Standard\classes And java default classpath ensure me that it loads helpme.class first looking in WowkInProgress, than, if not found, in AllPatches, than, if not found in standard Is it possible during Tomcat runtime to have something like that (possibly WITHOUT using jar) Thank you very much in advance. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tomcat 5 startup crash, please help
There is actually a listing in Bugzilla this. Would you mind adding your findings to it? http://issues.apache.org/bugzilla/show_bug.cgi?id=30052 If this is a jsvc bug, your data might help to find it. That's a pretty old Linux distribution. I remember having trouble with Sun's jdk on either RH7.0 or RH7.1 There was a fairly buggy release of the gclib libraries in one of them. Are you able to try your app on a more recent Linux distribution for comparison?

Tomcat 5 startup crash, please help
Hello, I am desperate, for I have been trying to find a solution to this problem for two weeks now. Can anybody help me with this? Tomcat 5 crashes as it is starting up using jsvc. It does not crash if I start Tomcat 5 as a regular application. It could be connected to struts and database connections, since it seems to be starting fine until the applications initialize the connections. Any hint or help is very much appreciated Michael Kastner - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tomcat 5 startup crash, please help
A stack trace or some other error report would help. It's a bit vague when you simply describe it. Show the evidence and you will be more likely to get assistance.

Hi,
Use init(ServletConfig config) method of servlet for
init parameters. bcs, init parameters will be set only
once it is initialised... so, u have to do the same in
the init() method only...

Yes, but you must first help us to help you: please post relevant files (in this case, the web.xml from the app that doesn't work) and give a more detailed problem description.

I have been struggling with Tomcat for several days and I am at the end of my rope. If I come across as irritated, I apologize in advance. I simply want to learn how to write JSP. I have a book and I want to start working through it, but I am having trouble setting up a server to serve JSP. I currently run Apache to serve HTML and PHP. Ideally, I'd simply like Apache to start recognizing JSP and handling it appropriately. Unfortunately that seems to not be an easy task... I have tried using mod_jk to connect Tomcat and Apache, with no luck. I finally gave up on trying to use Apache and I was just going to keep them separate. Now, how do I tell Tomcat to serve my jsp files??? I tried using the manager web program to add an application pointing to the correct directory, it accepts the command, but nothing is added to the application list and it doesn't serve the content like I expected it to. Finally I said screw it, I'll simply put my experiment files in the document root of Tomcat and use that for now. Still no luck, it serves up the same default stuff, even when I rename the file. My environment is the following: Fedora Core 2, Apache 2.0.51, Tomcat 5.5.4, JDK 1.5.0. Ideally I'd like to do what I talked about earlier, having Apache automagically know what to do with *.jsp files. However, I'll take what I can get! Thank you very much in advance.

Just run a standalone tomcat. Connecting to Apache is real work and you don't need it. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Please help...
Tomcat is organized differently than Apache. First of all Apache has a document root, where you can put all of your php and html files in. With tomcat, the directory structure is different. If you want to get started with tomcat, I suggest first creating directory under the webapps directory of your tomcat installation. For this example, lets call it test. Under test we will create a WEB-INF directory. The WEB-INF directory contains basically the configuration file for your web application you will be creating in the test directory. In the WEB-INF folder, create a file called web.xml. So at this point you should have directory structure that looks like this. Test WEB-INF web.xml Now edit the web.xml file to contain the following: ---snip ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN http://java.sun.com/dtd/web-app_2_3.dtd; web-app display-nameA test web application/display-name description Your test web application /description /web-app ---snip Now that you have an empty web application container set up, add some jsp files. Keep in mind that everything under the WEB-INF directory is protected by tomcat. You would not want someone to browse through your configuration now would you? For simplicity sake, lets create a test jsp page now. Create a file called index.jsp directly under the directory test. This is what your directory structure should look like now under your test directory: Test index.jsp WEB-INF web.xml Lets add some content under your test.jsp. We will combine some html with java code to demonstrate how things work. [EMAIL PROTECTED] contentType=text/html% !-- page directive -- [EMAIL PROTECTED] pageEncoding=UTF-8% html headtitleYour first cool page/title/head body %out.println(Hello world)% !-- jsp code -- /body /html Ok, make sure you have tomcat started. On windows, go to services and see if the service is running. On linux, type ps -ef or ps -aux on unix. If it is not running, you need to start this service for your platform. Next, browse to the machine where you have tomcat installed. It might be on the same machine your programming on. http://localhost:8080/test/ You should see hello world now. By default, Tomcat runs on port 8080. You must specify the port number in your browser. You can configure Tomcat to run on port 80 if you wish, but that is out of the scope of this document. Oops, I just read you are using fedora core. I am using fedora core. I have apache and tomcat set up to talk to each other using mod_jk2. I can send you my configuration files if you wish. I hope this was not too basic for you. Randall -Original Message- From: Ken Keefe [mailto:[EMAIL PROTECTED] Sent: Friday, November 12, 2004 1:14 PM To: [EMAIL PROTECTED] Subject: Please help...

RE: Please help...
First get familiar with Tomcat, its very daunting of a task connection apache and tomcat with mod_jk2, but not impossible. Use tomcat standalone, the one guy had a pretty straightforward and easy way of doing it, after you get :8080/test/ working you can move to serving over port 80 with Tomcat, then if you want to dive in and do apache+tomcat+mod_jk2 I would suggest you look at these places. http://www.cymulacrum.net/writings/tomcat5/book1.html http://www.linuxjava.net/howto/webapp/ http://johnturner.com/howto/apache-tomcat-howto.html there are more, many more. start slow, nothing more frustrating then getting something to work and then doing 30 steps and retrying and seeing it not working. do one thing at a time, there isnt a whole lot of steps. good luck, and if you get stuck dont hesitate to search the archives and see how many of us were in your shoes.

Hi folks, I am currently running apache 2.0.52 , mod_jk2, solaris 8 tomcat 5.0.28 on my servers . I have two apache serves behind an alteon that service my webapps on 4 tomcat servers. I have sticky sessions with a file store set up on my boxes. My filestore is via nfs. All my hosts are on the same subnet. They are mulithomed hosts because I need a back interface for the webapps to talk to the db. But my default routes are all set the same . I have one apache server that hits two tomcat servers and then another apache sever that has two other tomcat servers. Once I start that apache servers everything is fine , for a few hours . After a few hours the tomcat servers start to time out. I can get to the apache index page but as soon as I ask the apache server to make a request to a webapp on the tomcat servers is just sits there and times out. Sometimes the webapp does pop up but very slowly. I have examined the routing tables , I have done traceroutes I have pin pointed my problem down to the application layer. So I must be doing something wrong in my configuration. I checked over my configuration a hundred times and I did it exactly the way the book told me to professional apache tomcat 5 . This all worked on my testing environment , but it is not working now. I have included a very small tar file that has my config files . If any of you can give me an example of a working config or tell me what I am doing wrong I would greatly appreciate it . -Pablo - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

This is because the oracle dll is not found int the PATH environment variable. For this you should have Oracle client installed.

Please help: Apache direct Servlet to Tomcat
My Apache 2.0.49 Tomcat 5.0.19, windows 2000. I have a difficult in running servlet from Apache. For example I have a servlet TestServlet.class (package: myServlet) in C:\Program Files\Apache Group\Apache2\tomcat\webapps\ROOT\WEB-INF\classes\myServlet\ I register this servlet in \tomcat\webapps\ROOT\WEB-INF\web.xml: servlet servlet-nameTestServlet/servlet-name servlet-classTestServlet/servlet-class /servlet servlet-mapping servlet-nameTestServlet/servlet-name url-pattern/TestServlet/url-pattern /servlet-mapping Tomcat port is 8008 When I run http://localhost:8008/TestServlet, it runs correctly. Apache port is 82 I cannot start it with http://localhost:82/TestServlet. -- The page cannot be found My Aache and Tomcat is connected correctly. All JSP files can run on both. For example, I have a jsp file C:\Program Files\Apache Group\Apache2\tomcat\webapps\ROOT\testJSP\testDBPool.jsp. I can run http://localhost:82/testJSP/testDBPool.jsp or http://localhost:8008/testJSP/testDBPool.jsp in workers2.properties, I have: [uri:/myServlet/*] group=lb [uri:/WEB-INF/*] group=lb [uri:/WEB-INF/classes/*] group=lb Please forward your instruction.

Hmmm, except you said it runs correctly when accessing directly through Tomcat on port 8008. I've always avoided accessing the ROOT webapp through Apache to avoid these kind of issues, because of the additional ambiguity that it introduces. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
