 Posted: Tue Aug 03, 2010 12:50 am Post subject: Netbeans 6.9 Maven Web App, can't debug |
 |
|
Hi,
I'm using the default installation of Netbeans 6.9 (Build 201006101454), I've downloaded the "Java" package which includes, Glassfish, EE and all that other goodness.
The problem I am having is that when I create a new maven web application and I try to debug it, it simply wont let me. Now, I don't know if it's a bug in Netbeans or I am doing something wrong. So what I am hoping is that someone on here can confirm either one of those two assumptions.
Here's a step by step way of reproducing the problem.
New -> Project
Maven -> Maven Web Application
Accept defaults or enter an app name
Expand the newly created project and select
New -> Other
Web -> Servlet
Accept default classname or enter a name
use the same package structure you entered or left as default when creating the project
next
tick "Add information to deployment descriptor (web.xml)"
finish
expand Web Pages -> Web-INF
double click web.xml
click Servlets
enter 1 in the startup order
double click on the new servlet and paste this code in the file
| Code: |
@Override
public void init(ServletConfig config) throws ServletException {
try{
System.out.println("Hello Cruel World");
}catch(Exception ex){
ex.printStackTrace();
}
}
|
Put a breakpoint on the System out.
Right click the project and select debug.
When it prompts you for a server, select glassfish v3
The breakpoint never gets executed. But the system out appears in the logs. So I know for a fact that the line is being executed, but it doesn't stop at the breakpoint.
Now, if I create a "normal" web application not a "maven web application" and follow the same steps, then I can debug everything as I would expect.
If I look at the log messages from the maven build output, then it looks like it's attempting to start the thing in debug mode.
<maven output snip>
NetBeans: Deploying on GlassFish Server 3
profile mode: false
debug mode: true
force redeploy: true
Starting GlassFish Server 3
</maven ouput snip>
<glassfish snip>
INFO: Perform lazy SSL initialization for the listener 'http-listener-2'

INFO: Hello Cruel World
INFO: Loading application com.mycompany_mavenproject4_war_1.0-SNAPSHOT at /mavenproject4
</glassfish snip>
EDIT : I should probably add that this is on Windows XP |

Update...
Kind of figured it out, you can't debug a project. You can only debug a file i.e. Ctrl + Shift + F5.
Must be an undocumented "feature" of maven. |

If a similar scenario works with an Ant-based project then I don't see any particular reason why it shouldn't work with a Maven-based project. Assume it is a bug and file
it please, with all the steps to reproduce you gave here. Product 'javaee', component 'maven'. |
