Inside event handlers refer to the DOM element as this : $('#theButton').click(function() { this.innerHTML = 'You Clicked!'; }); Or, use the .get() method outside: // return the whole list $('li').get(); // return the first item $('li').get(0); $('li')[0] // return the last item $('li').get(-1)

Use jQuery to submit a form by clicking a button not associated with the form. The jQuery submit method can also be used to associate an event handler on the form. <!DOCTYPE html> <html> <head> <title>jQuery Submit Form</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"> </script> <script type="text/javascript"> $(function() { // attach a handler on submit $('#myForm').submit(function() { alert('Before submit'); }); // submit form with onclick $('#submit').click(function() { alert('Button clicked'); $('#myForm').submit(); }); }); </script> </head> <body> <form id="myForm"> Enter Your Name: <input type="text" name="name"><br> </form> <!-- button outside of form. --> <button id="submit">Submit</button> </body> </html> To submit the first form on the page: $('form:first').submit();

The first form iterates over a jQuery object and executes a function for each matched element. This is an example from jQuery documentation: <!DOCTYPE html> <html> <head> <style> ul { font-size:18px; margin:0; } span { color:blue; text-decoration:underline; cursor:pointer; } .example { font-style:italic; } </style> <script src="http://code.jquery.com/jquery-latest.min.js"></script> </head> <body> To do list: <span>(click here to change)</span> <ul> <li>Eat</li> <li>Sleep</li> <li>Be merry</li> </ul> <script> $("span").click(function () { $("li").each(function(){ $(this).toggleClass("example"); }); }); </script> </body> </html> The second form iterates over a general collection (examples from jQuery documentation): $.each([52, 97], function(index, value) { alert(index + ': ' + value); }); var map = { 'flammable': 'inflammable', 'duh': 'no duh' }; $.each(map, function(key, value) { alert(key + ': ' + value); }); $.each( { name: "John", lang: "JS" }, function(k, ...

This XML signature validator comes from the Apache XML Security project. It validates the signature according to the core validation processing rules . It does not verify that the key used to generate the signature is a trusted key. You can override the KeySelector class to make sure that the signing key is from a trusted store. import javax.xml.crypto.*; import javax.xml.crypto.dsig.*; import javax.xml.crypto.dom.*; import javax.xml.crypto.dsig.dom.DOMValidateContext; import javax.xml.crypto.dsig.keyinfo.*; import java.io.FileInputStream; import java.security.*; import java.security.interfaces.*; import java.util.Collections; import java.util.Iterator; import java.util.List; import javax.xml.parsers.DocumentBuilderFactory; import org.w3c.dom.Document; import org.w3c.dom.NodeList; /** * This is a simple example of validating an XML * Signature using the JSR 105 API.

Java SE 6 contains built-in utilities to generate XML signatures. This is an example that generates XML signatures using a Java keystore. It has options to generate signature for the whole document, for an element with a specific ID, or for elements matched by an XPATH expression. The XML document used to test is taken from Getting Started with XML Security : <?xml version="1.0"?> <PatientRecord> <Name>John Doe</Name> <Account id="acct">123456</Account> <Visit date="10pm March 10, 2002"> <Diagnosis>Broken second metacarpal</Diagnosis> </Visit> </PatientRecord> This is the Java code: import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.OutputStream; import java.security.*; import java.security.cert.X509Certificate; import java.util.*; import javax.xml.crypto.*; import javax.xml.crypto.dsig.*; import javax.xml.crypto.dom.*; import javax.xml.crypto.dsig.dom.DOMSignContext; import javax.xml.crypto.dsig.keyinfo.*; import javax.xml.crypto.dsig.spec.*; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.transform.*; import javax.xml.transform.dom.DOMSource; import javax.xml.transform.stream.StreamResult; import javax.xml.xpath.*; import org.w3c.dom.*; /** * Sign XML file. ...

For the default profile, the admin password is stored in the file server/default/conf/props/jmx-console-users.properties . Simply change the password and save: # A sample users.properties file for use with the UsersRolesLoginModule admin=YourNewTopSecretPassword But most likely you are trying to secure the JBOSS server in a production environment, and changing the password only isn't enough. For example, the JMX console is still wide open after you made the above change. Securing the JMX Console and Web Console is quite a daunting task!

I got this error while starting jboss-5.1.0.GA on Solaris (there were no problems on Windows XP or Linux). 18:20:57,405 ERROR [AbstractKernelController] Error installing to Instantiated: name=AttachmentStore state=Described java.lang.IllegalArgumentException: Wrong arguments. new for target java.lang. reflect.Constructor expected=[java.net.URI] actual=[java.io.File] at org.jboss.reflect.plugins.introspection.ReflectionUtils.handleErrors( ReflectionUtils.java:395) at org.jboss.reflect.plugins.introspection.ReflectionUtils.newInstance(R eflectionUtils.java:153) at org.jboss.reflect.plugins.introspection.ReflectConstructorInfoImpl.ne wInstance(ReflectConstructorInfoImpl.java:106) at org.jboss.joinpoint.plugins.BasicConstructorJoinPoint.dispatch(BasicC onstructorJoinPoint.java:80) at org.jboss.aop.microcontainer.integration.AOPConstructorJoinpoint.crea teTarget(AOPConstructorJoinpoint.java:282) at org.jboss.aop.microcontainer.integration.AOPConstructorJoinpoint.disp atch(AOPConstructorJoinpoint.java:103) at org.jboss.kernel.plugins.dependency.KernelControllerContextAction$Joi npointDispatchWrapper.execute(KernelControllerContextAction.java:241) at org.jboss.kernel.plugins.dependency.ExecutionWrapper.execute(Executio nWrapper.java:47) at org.jboss.kernel.plugins.dependency.KernelControllerContextAction.dis patchExecutionWrapper(KernelControllerContextAction.java:109) It turned out that this was a bug in jboss-5.1.0.GA and was fixed in jboss 6.
