     * as described below.
     * First, an object of a subclass of {@link RMIServerImpl} is
     * required, to export the connector server through RMI:
     * <ul>
     * <li>If an <code>RMIServerImpl</code> was supplied to the
     * constructor, it is used.
     * <li>Otherwise, if the protocol part of the
     * <code>JMXServiceURL</code> supplied to the constructor was
     * <code>iiop</code>, an object of type {@link RMIIIOPServerImpl}
     * is created.
     * <li>Otherwise, if the <code>JMXServiceURL</code>
     * was null, or its protocol part was <code>rmi</code>, an object
     * of type {@link RMIJRMPServerImpl} is created.
     * <li>Otherwise, the implementation can create an
     * implementation-specific {@link RMIServerImpl} or it can throw
     * {@link MalformedURLException}.
     * </ul>
     * If the given address includes a JNDI directory URL as
     * specified in the package documentation for {@link
     * javax.management.remote.rmi}, then this
     * <code>RMIConnectorServer</code> will bootstrap by binding the
     * <code>RMIServerImpl</code> to the given address.
     * If the URL path part of the <code>JMXServiceURL</code> was
     * empty or a single slash (<code>/</code>), then the RMI object
     * will not be bound to a directory.  Instead, a reference to it
     * will be encoded in the URL path of the RMIConnectorServer
     * address (returned by {@link #getAddress()}).  The encodings for
     * <code>rmi</code> and <code>iiop</code> are described in the
     * package documentation for {@link
     * javax.management.remote.rmi}.
     * The behavior when the URL path is neither empty nor a JNDI
     * directory URL, or when the protocol is neither <code>rmi</code>
     * nor <code>iiop</code>, is implementation defined, and may
     * include throwing {@link MalformedURLException} when the
     * connector server is created or when it is started.
     * @exception IllegalStateException if the connector server has
     * not been attached to an MBean server.
     * @exception IOException if the connector server cannot be
     * started.

/**
     * Sets the current URL being displayed.  The content type of the

     * non-<code>null</code>, then
     * a new default document is created and the URL is read into it.
     * If the URL contains and reference location, the location will
     * be scrolled to by calling the <code>scrollToReference</code> 
     * method. If the desired URL is the one currently being displayed, 
     * the document will not be reloaded. To force a document
     * reload it is necessary to clear the stream description property 
     * of the document. The following code shows how this can be done:
     * 
     *   Document doc = jEditorPane.getDocument();
     *   doc.putProperty(Document.StreamDescriptionProperty, null);
     * 
     * If the desired URL is not the one currently being
     * displayed, the <code>getStream</code> method is called to
     * give subclasses control over the stream provided.
     * This may load either synchronously or asynchronously
     * depending upon the document returned by the <code>EditorKit</code>.
     * If the <code>Document</code> is of type
     * <code>AbstractDocument</code> and has a value returned by 
     * <code>AbstractDocument.getAsynchronousLoadPriority</code>
     * that is greater than or equal to zero, the page will be
     * loaded on a separate thread using that priority.
     * If the document is loaded synchronously, it will be
     * filled in with the stream prior to being installed into
     * the editor with a call to <code>setDocument</code>, which
     * is bound and will fire a property change event.  If an
     * <code>IOException</code> is thrown the partially loaded
     * document will
     * be discarded and neither the document or page property
     * change events will be fired.  If the document is 
     * successfully loaded and installed, a view will be
     * built for it by the UI which will then be scrolled if 
     * necessary, and then the page property change event
     * will be fired.
     * If the document is loaded asynchronously, the document
     * will be installed into the editor immediately using a
     * call to <code>setDocument</code> which will fire a 
     * document property change event, then a thread will be
     * created which will begin doing the actual loading.  
     * In this case, the page property change event will not be 
     * fired by the call to this method directly, but rather will be 
     * fired when the thread doing the loading has finished.
     * It will also be fired on the event-dispatch thread.
     * Since the calling thread can not throw an <code>IOException</code>
     * in the event of failure on the other thread, the page 
     * property change event will be fired when the other 
     * thread is done whether the load was successful or not.

NullPointerException

java.lang.NullPointerException NullPointerException is described in the javadoc comments as: Thrown when an application attempts to use null in a case where an object is required. These include: Calling the instance method of a null object. Accessing or modifying the field of a null object. Taking the length of null as if it were an array. Accessing or modifying the slots of null as if it were an array. Throwing null as if it were a Throwable value. Applications should throw instances of this class to indicate other illegal uses of the null object. author: unascribed version: 1.19, 12/19/03 since: JDK1.0 Where is this exception thrown?

Recovering WebLogic Passwords

In one of my previous articles ( here ) I explained that the SerializedSystemIni.dat file in WebLogic contains the key used to encrypt and decrypt passwords. If you're not currently keeping this file secure I suggest you do, as with it someone can (to name a few things): Decrypt the WebLogic admin username and password from boot.properties. Recover database passwords, if JDBC Connection pools are configured, from config.xml. Recover the keystore passwords from config.xml and obtain SSL certificates stored in the jks keystores. Essentially, they can do whatever they want, so if you don't know who can read your SerializedSystemIni.dat files, look... now. In this article I will show how easy it is for this file to be used to recover lost passwords via a simple WLST script. The Script The script I use to decrypt passwords is incredibly short, and it works with WebLogic 8, 9 and 10 (probably for version 7 too). To use it, just create a new file called decryptpwd.py and paste the fol...
