Cannot invoke Tomcat manager: Server returned HTTP response code: 401

I am trying to deploy a war to a remote tomcat server from maven, but I get the following error in NetBeans:

Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy (default-cli)
on project noca: Cannot invoke Tomcat manager:
Server returned HTTP response code: 401 for URL:
http://12.34.56.78/manager/html/deploy?path=%2Fnoca&war= -> [Help 1]

I find it strange that there is no value for war and I don't know why.

When I browse this URL, I get the following in Tomcat's manager:

FAIL - Invalid context path null was specifi开发者_StackOverflowed

Here is my pom.xml:

The server is properly defined in my maven setting.xml.

What am I doing wrong?

P.S.: I have seen this similar question, but it does not answer the issue I have.

SOLUTION

For the record, I modified my pom.xml as following following Alexey's suggestion and it works:

    <!-- plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>tomcat-maven-plugin</artifactId>
        <configuration>
            <server>Plasma01</server>
            <url>http://12.34.56.78/manager/html</url>
        </configuration>
    </plugin -->

    <plugin>
        <groupId>org.codehaus.cargo</groupId>
        <artifactId>cargo-maven2-plugin</artifactId>
        <configuration>
            <container>
                <containerId>tomcat6x</containerId>
                <type>remote</type>
            </container>
        <configuration>
        <type>runtime</type>
        <properties>
            <cargo.tomcat.manager.url>
                http://12.34.56.78/manager
            </cargo.tomcat.manager.url>
            <cargo.remote.username>xxxx</cargo.remote.username>
            <cargo.remote.password>yyyy</cargo.remote.password>
        </properties>
        </configuration>
            <deployer>
                <type>remote</type>
                <deployables>
                    <deployable>
                        <groupId>net.test</groupId>
                        <artifactId>noca</artifactId>
                        <type>war</type>
                    </deployable>
                </deployables>
            </deployer>
        </configuration>
    </plugin>

Try to user cargo to control tomcat and deployment, it's easy and worked.
