  • 0

I am trying to get a simple helloworld test project going so I can build upon it. I am using Java EE with maven in Eclipse and am getting a Requested reseource is not available error from tomcat in my web browser.

Right now all I have is a test jsp page to print Hello World which is all I am trying to get working. I created a maven project using the command mvn archetype:generate .. to generate the project structure which I then imported into Eclipse. I then added a dynamic web facet to the project.

The following is what my web.xml file looks like:

<!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-name>Archetype Created Web Application</display-name>

<welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>

How do I get tomcat to pick up my index.jsp file so that I can display it? Am I missing something in my web.xml file? I have a tomcat server running from within eclipse so this is not the problem. Would I need a servlet mapping entry in my web.xml? I am just really lost as to how this all fits together. Any help would be great.

This is the command I used to generate the maven project:

mvn archetype:generate -DarchetypeArtifactId=maven-archetype-webapp \
                   -DgroupId=com.mycompany.app \
                   -DartifactId=my-webapp \
                   -Dversion=1.0-SNAPSHOT

Thanks

    I created a maven project using the command mvn archetype:generate ... to generate the project structure which I then imported into Eclipse. I then added a dynamic web facet to the project.

    You shouldn’t have to add any facet, things should just work if your project has a packaging of type war.

    It would thus have been nice to provide the full command you used to create your project with the archetype plugin. Did you use the maven-archetype-webapp archetype? Did you ran something like that:

    mvn archetype:generate -DarchetypeArtifactId=maven-archetype-webapp \
  -DgroupId=my.group.id -DartifactId=my-artifact -Dversion=1.0-SNAPSHOT

    If not, then be sure that your pom has a <packaging>war</packaging> and that you use the default structure for a war project (see Usage for an example).

    Then, what plugin are you using for the Eclipse integration? How did you import the project into Eclipse?

    If you are using the maven-eclipse-plugin (if you ran eclipse:eclipse), then you need to
    configure it for WTP support. You need to pass the wtpversion on the command line (or to configure the plugin in the POM):

    mvn -Dwtpversion=2.0 eclipse:eclipse

    If you are using m2eclipse, then just import your project as a Maven Project (right-click the Package Explorer then Import… > Maven Projects).

    In both case, your project should be recognized as a Dynamic Web Module that you can Run on Server). There is nothing manual to configure for this (no facet to add).

    Update: Did you install the Maven Integration for WTP (Optional) when installing m2eclipse?
