Re: JNDI Datasource question
Jake, thanks, this is a great answer and answers my question exactly. :) Especially the META-INF/context.xml. was somthing that I must have overlooked Ron On Mon, 2002-12-02 at 11:09, Jacob Kjome wrote: Hi Ron, That is referring to a context configuration file. You *always* need to set up your DataSources through the proprietary server configuration. The stuff in the web.xml only defines the interface. For instance, if you set up DBCP specific stuff in the web.xml file, your app would be dependent on running under Tomcat and be incompatible with every other app server. JNDI is meant to provide a standard interface while allowing the vendor to provide a proprietary implementation. That way, you get to code to a standard and you get to pick the vendor who provides the best implementation (by your own definition). That provides for both standards *and* market competition. Neat, eh? See the following for context configuration files: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html#Automatic%20Application%20Deployment Also, look at admin.xml and manager.xml in CATALINA_HOME/webapps for reference. I addition, Craig R. McClanahan pointed out the following when deploying via the manager app: quote For the deploy command, simply include your context confgiuration file in the WAR at META-INF/context.xml. In Tomcat 4.1, you can dynamically deploy a context configuration file instead of, or along with your webapp. Such a file can contain the Context element, and all nested subelements, from what you would normally put in server.xml, so you can indeed dynamically deploy an app with a custom realm. /quote Jake -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
JNDI Datasource question
Evening A question to grow my knowledge:) On tomcat 4.1.12-LE-jdk14 deployment with java jsdk 1.4.1_01-b01 I have installed the two missing jar files from commons (dbcp and pool) and made the example from the documentation (/DBTest) work. Great work, well written and very clear. So my question. If I want to use DataSources I always need to change or add Contect (or defaultContext) in the conf/server.xml? According to the documentation I can define a Resource as: Context ... ... Resource name=jdbc/EmployeeDB auth=Container type=javax.sql.DataSource description=Employees Database for HR Applications/ ... /Context in server.xml or as resource-ref descriptionEmployees Database for HR Applications/description res-ref-namejdbc/EmployeeDB/res-ref-name res-ref-typejavax.sql.DataSource/res-ref-type res-authContainer/res-auth /resource-ref int web.xml of an application that is deployed. But where to I put all the values named in the ResourceParams entries if I want to declare them from the web.xml file?

Re: package declaration / import - new improved!
Your bean needs a constructor without arguments like:
public class Abean {
public Abean () {
// does nothing
}
}
this way the bean can be instanciated.

Hi,
Similar to a recent posting, after some research into the subject,
regarding importing a package into my JSP, I understand thus:
If I have Abean.java and of course Abean.class belonging to package mybean
(source below), in webapps/mydir/WEB-INF/mybean/mybean.class, and my JSP
in webapps/mydir/index.jsp that includes the bean:
%@ page language=java %
%@ page import=mybean.* %
html
headtitle/title/head
bodyTEST/body
/html
I get the error package mybean does not exist
import mybean.*;
The bean source (only for the technically minded now):
package mybean;
public class Abean {
public int aMethod() {
int i = 10;
return i;
}
}
What am I doing wrong here please? Please someone help!
thanks
Paul.

RE: How to add a servlet to a new Webapp

Re: tomcat sessions and webapp deployment
Morning Nope, Tomcat 4.1.x will hang onto the sessions. And the even worse news is that Tomcat 3.3.2-dev will now hang onto the sessions across a context-reload :). This is not the behaviour I see.Sessions are invalidated after an ant reload on tomcat 4.1.12-LE on a semislackware install Ron -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Apache-Tomcat Conf
To get tomcat to generate the mod_jk.conf file I had to do the following: just after the Server line in server.xml add: Listener className=org.apache.ajp.tomcat4.config.ApacheConfig modJk=/opt/apache2/lib/mod_jk.so workersConfig=/opt/tomcat/conf/jk/workers.properties/ then find the default virtual host and add: Listener className=org.apache.ajp.tomcat4.config.ApacheConfig append=true forwardAll=true That's it. Some notes though * if you are using apache 2.0.43, you need to compile mod_jk yourself * once the file has been created. I find it best to copy it to a safe place and make any needed changes by hand Ron On Sat, 2002-11-23 at 12:50, Nitesh Garg wrote: I hv downloaded Apache/Tomcat 4.1.12 and have apache 2.0, I want to configure my tomv\cat with apache.

apache and tomcat and a webapp
This might not even be possible but I cannot find a definitive yes or no answer I am developing a webapp based on jsp and servlets. Once this is done I want to deploy it on a server that has several domains on it. Currently this server is running apache with JServ. My idea is to have apache 2.0.X together with tomcat 4.1.12 to take over this work. I have managed to get apache to talk to tomcat using the mod_jk connector. But I can only access my application by using the application path (http://localhost/application/) instead of having served up as the root of the virtual host (http://localhost/). How to go about this? Ron Smits [EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: apache and tomcat and a webapp
Let me try and be more specific :) First of all, if I get all to work the current setup with JServ will disappear and I am testing this in a test environment (Vmware) So let me see if I can chop my questions up in different parts The application is being developed using tomcat 4.1.12 running standalone. The development is going nice and contacting the application on localhost:8080/application is perfect. Question 1: I want the application to be the root of the tomcat. Meaning that in my test environment when I contact localhost:8080 I get the application and not the standard Tomcat page. I edited the server.xml and changed the Root context to point to the application: Context path= docBase=application debug=0/ I even removed the ROOT directory. When starting this up going to localhost:8080 will give me a No context configured to process this request If I go to localhost:8080/application my application is there. So how do I change this? Because the current server that needs to be replaced is running several domains in a virtual setup (and very nicely too thanks to apache). My idea is to remove the current 1.3 install with JServ and replace it with apache 2.0.43 that will run all the virtual hosts and will talk to tomcat for the web application (see question 1) that will be in a new virtual host. So after I have been able to get question 1 answered (replacing the root context with my application) the next question will be what the best way is of setting mod_jk up to serve up the application when apache gets a request for this application. I hope this is more clearer Ron PS to fullfill the list: OS linux version 2.4.19 TOMCAT 4.1.12 JDK: jsdk1.4.1_1 Hardware never enough but it is a big enough intel box :) Network: running fine, thank you :) -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
