Netbeans and Tomcat

Hello all.
I have some confusion using Netbeans (v6.1) and Tomcat (v6).
I have developed a Website that uses a MySql DB. The Website execute on the port 8080 with a DB named "Dev" and in a context call "/Dev" so I can access my application with "http://localhost:8080/Dev/". It works perfectly and everything is beautiful. I think it runs under the Tomcat_base that Netbeans includes (under /home/user/.netbeans/...).
Then I want to put this Website in a kind of Production environment. So I copy the built .war to the "webapps" of my Tomcat (under /usr/local/tomcat...) and start the Tomcat server. I configured this Tomcat to work on the port 80 and in a context called "/Prod" so I should be able to run the application with "http://localhost/Prod/".
The question is: I have different Databases for both environments (I mean different DB running on the same Mysql), so I don't know how to do the Dev-Prod change or configure it in an elegant way. I think I can just develop the Website in Development and before copying the .war file to Production, change both the path and the DB name in the "context.xml" file, and then build the WAR. I guess it must be a better way to do it, but I don't know it.
Can someone give me some advice please?
I appreciate your help, thank you very much.
Sarah.

I believe this is the way to do it:
If your context is called MyProject, I imagine under tomcat/conf/catalina/localhost there is a file called MyProject.xml. You put configuration information such as database connection info in this file. This file should not be within the war file so when you alter MyProject and deploy it, it doesn't alter this file. In Eclipse IDE, you do not give it permission to alter this file (the option is a checkbox in one of the menu items), note: let it auto-generate it the first time, then yurn off that feature. Your production enviornment will have a different MyProject.xml file than your development enviornemnt. I suggest changing the file to read-only in both production and development so it doesn't accidently get altered.

Communication problem between NetBeans and Tomcat

hi!
i got a quite mysterious problem. here is what happens:
- i start NetBeans 5.5.1 (the first time)
- i want to debug my JSF-Project, the Debugger starts
- After a few seconds the debugger waits for tomcat (it sais: "Waiting for Tomcat...") and tomcat starts
- Again after a few seconds the tomcat-debugger-output sais "Tomcat startet in 3333 ms".
okay.
when i enter http://localhost:8084/ in my browser i get the tomcat homepage, so the server has definitely started! But nothing happens in NetBeans and nothing happens with my project....
In the lower-right corner i see this blue working-bar that sais "deploying project" but nothing happens. The Project-Debugger-Output still sais "Waiting for Tomcat..." but nothing happens...
And after something around 3 minutes (i guess it's a timeout) i get the error "Starting of Tomcat failed." But is HAS started, i can login to the Administration-Area in my browser!
so i guess there is a communication problem between netbeans an tomcat. Netbeans waits for a message from tomcat but tomcat doesn't send it..or netbeans doesn't understand it.
But the story goes on:
When i press the debug-button a second time it takes only a few seconds till i get the message: "Tomcat server port 8084 already in use". OF COURSE! Because Tomcat has already startet and can't be stoped by NetBeans.
i'm trying to solve this problem for 4 days now, so i would be very happy if anyone has an idea where to start/continue the search...
thanks,
flo.

NetBeans and tomcat 5.0 work in a different manner

If I compile the servlet Contatore.java by means of NetBeans, it's ok only if I execute it by means of Netbeans with the following url in my browser
http://localhost:8084/servlet/Contatore
on the contrary if I execute it by means of Tomcat 5.0 only changing the port from 8084 ti 8080,
http://localhost:8080/servlet/Contatore
then I have the following error
HTTP Status 404 - /servlet/Contatore
type Status report
message /servlet/Contatore
description The requested resource (/servlet/Contatore) is not
available.
Apache Tomcat/5.0.24
Can someone explain me why these 2 differente behaviours
Perhaps is it impossible to use a folder named "servlet" ?
Thanks
Eugenia Mariani

I thought NetBeans used Tomcat as its servlet/JSP engine, no?
The /servlet context is special in Tomcat. You invoke servlets that aren't mapped in the web.xml using URL http://host/ContextName/servlet/ServletName. When you give a URL like http://localhost:8080/servlet/Contatore, you're asking Tomcat to invoke a servlet named Contatore in the default ROOT context. Is there such a thing?
Tomcat prefers that servlets and Java Beans be in packages these days. If it's not, there might be problems.
I wouldn't name a context of mine "servlet". I don't deploy apps of mine in the default ROOT context, either. I create a context for each Web app.

NetBeans 5.0 and Tomcat 4.1

Hello,
I'm using NetBeans 5.0 and I have been using the Bundled Tomcat version 5.5.9 for my servlet container and everything's been great. Now that I'm ready to push my application up to a web host, I found that my host (lunarpages) runs with Tomcat 4.1 which uses version 2.3 of the servlet container. Tomcat 5.5 uses servlet container 2.4.
So I downloaded Tomcat 4.1 (which has 2.3) and I don't know how to properly tell Netbeans to use it. When I open Server Manager and select 'Add Server', I can't just tell NetBeans to point to my Tomcat 4.1 directory. It wants me to select from a dropdown list of servers and Tomcat 4.1 isn't in the list.
I tried to fake NetBeans out by selecting the 'Tomcat 5' server and pointing to my Tomcat 4.1 directory but I'm getting the following message when I try to run:
FAIL - Unknown command /deploy
C:\workspace\myApp\nbproject\build-impl.xml:425: Deployment error:
Can anyone point me in the right direction on how to get Tomcat 4.1 running with NetBeans 5.0?
Thanks,
Eric

I found that my host (lunarpages) runs with Tomcat 4.1 which uses version 2.3 of the servlet containerPlease read the post before answering, the reasoning is crystal clear.
I don't have a concrete answer to this problem, but I do have a suggestion.
1) You can add your own tomcat server to netbeans. Under the runtime tab you will find servers, if you right click this you can add a server. Use this to manually configure your own server
2) as for the servlet spec problem, when creating a web project setting the java EE version to 1.3 might solve the problem... I can't tell this for sure because I've never done it.

NetBeans and JSP pages

I'm using the netBeans IDE to develope my project and the project is web application. But I've a problems with this IDE.
Q1. The default page is index.html and the default home for the project is say $HOME, when I write http://localhost:8084/$HOME/index.html the browser displace error message. I've to run this file from the netBeans. Do I need to run netBeans and run the file from the IDE to access the index.html file?
Q2. The second problem is; once I run the index file from the netBeans and then use this address http://localhost:8084/$HOME i.e if I remove the index.html file form the URL the Browser displays all the files that I've in my project but I don't won't this to happend. Is there any means to avoid this problem?
Thank you indavance.

I'm using the netBeans IDE to develope my project and

with this IDE.If you are new to application development, then I recommend not using any IDE - it is better to configure everything manually http://tomcat.apache.org/tomcat-6.0-doc/appdev/index.html to understand what's going on under the hood.
Once you understand what's going on, then it will be much easier to configure your IDE.

Glassfish with NetBeans and Eclipse

Hi,
I have both NetBeans Java EE and Eclipse IDE for Java EE Developers installed on my laptop. With NetBeans Java EE I have the installed the Glassfish and Tomcat server . Can I use/'integrate' this same Glassfish and Tomcat server with my Eclipse installation or is it advisable to install a "standalone" Glassfish &Tomcat server specific for my Eclipse environment?
Thanks.
Guy

Hi!
Yes you can integrate/use Glassfish and Tomcat with your Eclipse installation.
For Glassfish support in Eclipse (assuming you are using Eclipse Luna) you have to install first: http://marketplace.eclipse.org/content/glassfish-tools-luna
The integration is really simple: https://blogs.oracle.com/oepe/entry/getting_started_with_glassfish_4
Hope hits help,
Kind regards.

From netbeans to tomcat.

Hi all.
I downloaded netbeans and
I wrote a website using JSP and Servlets.
Now, I don't need the netbeans so ...
I downloaded only tomcat.
I entered the project's folder -> build -> web -> *.*
and copied all files and folders in this directory to webapps\Web1\
(Web1 is my project name).
Anyway, I can run and see the JSP files but I can't run the servlets.
I tried to compile all java files but..
When I'm compiling the files it says :
StepOneServlet.java:3: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
StepOneServlet.java:16: cannot find symbol
symbol: class HttpServlet
public class StepOneServlet extends HttpServlet {
^
StepOneServlet.java:18: cannot find symbol
symbol : class HttpServletRequest
location: class StepOneServlet
And theres alot more...
what should I do ?

well ...
netbeans makes it so easy !
Everything works great under netbeans !
my jsps, my servlets and jdbc.
Until now, I didn't need to set a CLASSPATH variable.
The problem is : netbeans takes memory !
To save memory I want to run only the tomcat server.
I know there is a tomcat server under netbeans
and I know where is my project's web.xml.
Anyway, I setup the CLASSPATH -> Tomcat's common/lib directory.
The errors gone but new errors appeared.
Here are few samples:
FinalServlet.java:4: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
FinalServlet.java:15: cannot find symbol
symbol: class HttpServlet
public class FinalServlet extends HttpServlet {
There is one type of error I can't understand.
under the folder "Source" I have my servlets..
Inside the folder "Source", there is another folder "beans"
with two java files in it (these file are my project's beans).
I tried without compiling the beans, I tried once after I compiled the beans and I keep getting these errors.
When I run from the folder "Source" the command javac *.java
It says:
FinalServlet.java:30: package beans does not exist
beans.Message m = (beans.Message)
request.getSession().getAttribute ("messageBean");
^
I tried put the *.class in the folder "source"
but I keep getting this errors and I don't know why !
Thank you all in advance.

Problem launching a jsp page with eclipse and tomcat

Hi,
I have just started using eclipse and tomcat for creating dynamic web pages. I tried to launch a jsp page after starting the tomcat server with the URL: http://locahost:8080/HelloWorld/, an error page was displayed as below:
HTTP Status 404 -/
type Status report
message /_
description The requested resource (-) is not available
Apache Tomcat/5.5.17
I didn't get any error at the console and when i just typed http://localhost, a pop up menu saying that the connection was refused when attempting to contact localhost.
I'm not sure what is the problem here. Could it be the permssion to the localhost is not granted by the system as the eclipse IDE is running using linux?
Hope someone can help.
Thanks.

Authentication problem with JWS and TOMCAT

Hi everyone !
I have a problem with Java Web Start (1.0.1) and Tomcat (4.0.4).
I'm trying to call my application via Web server Tomcat with restricting access.
My configuration is the following :
The deployment descriptor web.xml is:
<?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">

</mime-mapping>

</auth-constraint>
</security-constraint>

<login-config>

</login-config>
</web-app>
And jnlp File is:
<jnlp

<jar href="Jar10.jar"/>
<jar href="MyApplication.jar"/>
</resources>
<application-desc main-class="com.xxxx.tool.cm.MyApplication"/>
</jnlp>
With the above configuration the Java Web Start not work.
I'm expecting the message box for insert username and password instead it returns the messagge error :
An error occurred while launching/running the application.
Vendor: XXXX
Category: Download Error
Unable to load resource: http://host:8080/Official/Application.jnlp
The Exception error is:

I have tried to remove the restrict access in the deployment descriptor (web.xml) and java Web Start WORKS !!!!!!
I'll appreciate any idea or hint!
Thanks in advance

Why do I need to restart Apache and Tomcat every time a java file is change

If a java file is changed and complied the changes are not reflected if Tomcat is not restarted.
The settings in server.xml are as:

<Context path="/manager" docBase="manager" debug="0" privileged="true"/>
<Context path="/cf" docBase="cf" debug="0" reloadable="false"/>
Here "cf" is my Application folder under webapps. The reloadable property when set to "true" for standalone Tomcat on Windows98 reflects the changes for compiled java files without restarting Tomcat. But on Linux 7.1 with Apache 1.3.19 and Tomcat 4.0.3 this is not working.
Also tried out with Manager Application of tomcat-users.xml with reloadable="false" as well as reloadable="true",
But when I reload the application using the command
http://servername:8080/manager/reload?path=/appli.name
It tells me that the application is reloaded but changes in the java file are still not reflected.
Also when reloaded through Manager Servlet, Only my load-on-startup servlet is reloaded, but other java classes are not.
Is it neccessary to execute this reload command from the server itself. I m executing it from a remote m/c. and have mapped the application with a domain name virtually.
Is it the case with Tomcat on Linux with Apache. Or is something going wrong on my part.
Can someone Help out plz.

Rupali

or you can "touch" your web.xml file.
touch web.xmlor that command is for *nix systems, not sure what the Windows command is. But basically, when you edit the web.xml, even if it means updating the last modified time, it will restart only your application and you should see the changes.

Preinstalled apache, apache2 and tomcat

Hello,
I'm setting up a Sun Fire V490 running solaris 10 for use as a web server. I need to have Apache httpd version 2 and tomcat version 4.x to run.
So I found that the machine comes with apache httpd 2 preinstalled and also apache httpd 1 with fully integrated tomcat engine.
But as stated I need to have apache httpd 2 with tomcat running!
Apart from configuring the system to run httpd version 2 instead of version 1 by use of svcadm, I'm wondering how to get a solid solution to also have tomcat running. Ok I could simply install a tomcat version from apache.org, but I would like to ensure that this is the right solution for e.g. future upgrades.
So if anybody has got some more knowledge but this issue, I would be happy about letting me know!
Thanks, Raimund

Hey, I came into the same question while configuring tomact on Sun server.

Setting up eclipse and tomcat

Does anyone here have any expertise configuring these two products?(eclipse and tomcat)
I have my tomcat server running and it process them jsp pages just fine. I have also installed the plugin to get tomcat configured with eclispe.
I am just having problems running a jsp file directly from tomcat. it always points to a file on the hd and not to the webapps area like it's supposed to......

Sure - we use that combo for development all the time.
What's the problem specifically? Did you create a new Tomcat project in Eclipse? If you did, then it will automatically add the project's web path as a context to Tomcat, and you can browse directly to it using your browser.
FYI - note that the context that is created is going to point to the eclipse workspace directory - NOT the default webapps directory that you might have configured for Tomcat. That's OK.
