Method Detail

getRealPath

public static java.lang.String getRealPath(javax.servlet.ServletContext context2,

Identical to context2.getRealPath(pathInfoCGI). On BEA WebLogic, which has a broken getRealPath() implementation, we use context2.getResource(pathInfoCGI)) instead.

Parameters:

context2 - The servlet context.

Returns:

a valid path or null

req - The servlet request

Returns:

The local port or the value from the server port variable.

public static int getMBeanProperty(java.lang.String pattern,
                                   java.lang.String property)

Return an mbean property. Example: Util.getMBeanProperty("*:type=ThreadPool,name=http*", "maxThreads") or Util.getMBeanProperty("*:ServiceModule=*,J2EEServer=*,name=JettyWebConnector,j2eeType=*", "maxThreads");
