| <h1 class="topictitle1">Source and batch validation</h1> |
| <div><p></p> |
| <p>There are two types of validation that can occur when you are working with |
| source files in a structured source editor: source validation and batch validation. </p> |
| <div class="p">Source validation occurs as you type your code; this validation reflects |
| the "unsaved" and "unbuilt" contents of the source you are editing. For example, |
| if you were to type the following code in a JSP editor:<p><samp class="codeph"><foo:bar></samp></p> |
| where <samp class="codeph">foo:bar</samp>is |
| a tag that does not exist, the problem would be discovered immediately and |
| would appear underlined in the editor. The advantage of this type of validation |
| is that it can alert you to errors instantly.<div class="note"><span class="notetitle">Note:</span> To turn source validation |
| on (or off) for all structured text editors, click <span class="menucascade"><span class="uicontrol">Window</span> > <span class="uicontrol">Preferences</span> > <span class="uicontrol">General</span> > <span class="uicontrol">Editors</span> > <span class="uicontrol">Structured Text Editors</span></span> and check (or |
| uncheck) <strong>Report problems as you type</strong>.</div> |
| </div> |
| <div class="p">Batch validation occurs on saved files. It can catch build process errors |
| and other errors that the source validator cannot. For example, suppose you |
| typed the following in a JSP editor:<p><samp class="codeph"><%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%><br /> |
| <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%></samp></p> |
| In |
| this example, the same prefix is used twice. This would prompt the batch validator |
| to trigger markers and to generate build warnings in the Problems view and |
| in the Navigator. </div> |
| <p>Batch validation can uncover errors in multiple files at once and give |
| you a comprehensive view of where problematic code can be found in your project. |
| Moreover, you do not need to open files in an editor to run batch validation. |
| To run batch validation on specific files, select and right click the files |
| in the Project Explorer and then select <span class="menucascade"><span class="uicontrol">Validate</span></span> from the popup menu.</p> |
| <div class="note"><span class="notetitle">Note:</span> To set preferences for batch validation, click <span class="menucascade"><span class="uicontrol">Window</span> > <span class="uicontrol">Preferences</span> > <span class="uicontrol">Validation</span></span></div> |
