Creating and Editing Files 

 NetBeans IDE 3.6 


To create a new file:

  1. Choose File > New.
  2. Select a template and follow the instructions in the wizard.

To edit a file:

  1. Double-click the file's node in the Filesystems window.

    The Source Editor displays the source code for the file. If the file is a GUI form object, the Source Editor also opens a Form Editor tab.

If a Java source file contains compilation errors, the Source Editor underlines the code that is causing the errors in red. Put your mouse over the error glyph in the left margin of the file to see a description of the error. Common causes of errors are:

  • You did not mount your directory at the Java package root. The package root is the directory that contains the default package, or the uppermost directory in your source code's package structure. For example, for the Java class com.myapp.MyApp.java you must mount the directory that contains the com directory.
  • You have not mounted Java libraries that the source file depends on. To mount JAR file libraries, choose File > Mount Filesystem, then select Archive File and follow the steps in the wizard.
