What does 'URI has an authority component' mean?

I am attempting to build a Java web project on NetBeans 6.8, but I get get the following error:

The module has not been deployed.

It points to my build-impl.xml file, line 577:

<nbdeploy clientUrlPart="${client.urlPart}" debugmode="false" forceRedeploy="${forceRedeploy}"/>

The GlassFish v3 error log says:

SEVERE: Exception in command execution : java.lang.IllegalArgumentException: URI has an authority component
java.lang.IllegalArgumentException: URI has an authority component
  at java.io.File.<init>(File.java:368)`..., etc.

What does "URI has an authority component" mean?

An authority is a portion of a URI. Your error suggests that it was not expecting one. The authority section is shown below, it is what is known as the website part of the url.

From RFC3986 on URIs:

The following is an example URI and its component parts:

     foo://example.com:8042/over/there?name=ferret#nose
     \_/   \______________/\_________/ \_________/ \__/
      |           |            |            |        |
   scheme     authority       path        query   fragment
      |   _____________________|__
     / \ /                        \
     urn:example:animal:ferret:nose

So there are two formats, one with an authority and one not. Regarding slashes:

"When authority is not present, the path cannot begin with two slash
characters ("//")."

Source: https://tools.ietf.org/rfc/rfc3986.txt (search for text 'authority is not present, the path cannot begin with two slash')

The solution was simply that the URI was malformed (because the location of my project was over a "\\" UNC path). This issue was fixed when I used a local workspace.

Flip over to the GlassFish output tab, it'll give you better info. Netbeans gives you that generic error, but Glassfish gives you the details. When I get this it's usually a typo in one of my JSP or XML files...

I had the same problem (NetBeans 6.9.1) and the fix is so simple :)

I realized NetBeans didn't create a META-INF folder and thus no context.xml was found, so I create the META-INF folder under the main project folder and create file context.xml with the following content.

<?xml version="1.0" encoding="UTF-8"?>
    <Context antiJARLocking="true" path="/home"/>

And it runs :)

I found out that the URL of the application conflicted with a module in the Sun GlassFish. So, in the file sun-web.xml I renamed the <context-root>/servlets-samples</context-root>.

It is now working.

I also faced similar problem while working on Affable Bean e-commerce site development. I received an error:

Module has not been deployed.

I checked the sun-resources.xml file and found the following statements which resulted in the error.

<resources>

                   jndi-name="jdbc/affablebean"

                          connection-creation-retry-interval-in-seconds="10"
                          connection-leak-reclaim="false"

                          is-isolation-level-guaranteed="true"
                          lazy-connection-association="false"
                          lazy-connection-enlistment="false"
                          match-connections="false"

                          max-pool-size="32"
                          max-wait-time-in-millis="60000"
                          name="AffableBeanPool"
                          non-transactional-connections="false"
                          pool-resize-quantity="2"
                          res-type="javax.sql.ConnectionPoolDataSource"
                          statement-timeout-in-seconds="-1"
                          steady-pool-size="8"
                          validate-atmost-once-period-in-seconds="0"
                          wrap-jdbc-objects="false">

        <property name="User" value="root"/>
        <property name="Password" value="nbuser"/>
    </jdbc-connection-pool>
</resources>

Then I changed the statements to the following which is simple and works. I was able to run the file successfully.

<resources>
    <jdbc-resource enabled="true" jndi-name="jdbc/affablebean" object-type="user" pool-name="AffablebeanPool">
        <description/>
    </jdbc-resource>

        <property name="URL" value="jdbc:mysql://localhost:3306/AffableBean"/>
        <property name="User" value="root"/>
        <property name="Password" value="nbuser"/>
    </jdbc-connection-pool>
</resources>

After trying a skeleton project called "jsf-blank", which did not demonstrate this problem with xhtml files; I concluded that there was an unknown problem in my project. My solution may not have been too elegant, but it saved time. I backed up the code and other files I'd already developed, deleted the project, and started over - recreated the project. So far, I've added back most of the files and it looks pretty good.
