Usage

From source file:org.apache.catalina.util.ExtensionValidator.java

/**
 * Runtime validation of a Web Applicaiton.
 *
 * This method uses JNDI to look up the resources located under a 
 * <code>DirContext</code>. It locates Web Application MANIFEST.MF 
 * file in the /META-INF/ directory of the application and all 
 * MANIFEST.MF files in each JAR file located in the WEB-INF/lib 
 * directory and creates an <code>ArrayList</code> of 
 * <code>ManifestResorce<code> objects. These objects are then passed 
 * to the validateManifestResources method for validation.
 *
 * @param dirContext The JNDI root of the Web Application
 * @param context The context from which the Logger and path to the
 *                application/*from   w w w.  j  a v  a 2 s .  c  om*/
 *
 * @return true if all required extensions satisfied
