build-impl.xml:1031: The module has not been deployed

may its so late but the response useful for others so : Sometimes, when you don’t specify a server or servlet container at the creation of the project, NetBeans fails to create a context.xml file.

  1. In your project under Web Pages, create a folder called META-INF.

Do this by right mouse button clicking on Web pages, and select:

New->Other->Other->File Folder

Name the folder META-INF. Case is important, even on Windows.

  1. Create a file called context.xml in the META-INF folder.

Do this by right mouse button clicking on the new META-INF folder, and select:

New->Other->XML->XML Document

Name it context (NetBeans adds the .xml) Select Well-formed Document Press Finish

  1. Edit the new document (context.xml), and add the following: <?xml version="1.0" encoding="UTF-8"?> <Context antiJARLocking="true" path="/app-name"/>

Replace app-name with the name of your application.

Now your in-place deployment should work. If not, make sure that the file can be read by everyone.

The context.xml file is specific to Tomcat. For more information about that file, see the Tomcat documentation at tomcat.apache.org.
