Class ModuleConfigVerifier

java.lang.Object
  org.apache.struts.plugins.ModuleConfigVerifier

All Implemented Interfaces:

PlugIn

public class ModuleConfigVerifier
extends java.lang.Object
implements PlugIn

Convenient implementation of PlugIn that performs as many verification tests on the information stored in the ModuleConfig for this module as is practical. Based on the setting of the fatal property (which defaults to true), the detection of any such errors will cause a ServletException to be thrown from the init method, which will ultimately cause the initialization of your Struts controller servlet to fail.

Since:

Struts 1.1
