jogep — Mon, 17 Dec 2012 07:53:54 +0000

With jQuery UI 1.9 this popular JavaScript Library provides a Menu Widget, which is now also available in the Struts2 jQuery Plugin. jQuery UI 1.9 includes some API redesigns which also touches the Struts2 jQuery Plugin. So please respect the Upgrade Guide.

Menu Tag

The Menu Tag can be used with some manually added Menu Items or it can be generated form a List of Values. Two new Showcase Examples explain this.

     id="menuWithItems" cssStyle="width:50%">
         title="Struts2" href="http://struts.apache.org/2.x/index.html"/>

            >
        >
    >

Spinner Tag

The currently based Spinner Tag was based on an community jQuery plugin. This plugin was replaced by the Spinner Widget provided by the jQuery UI Lib itself. This brings some API Changes, especially the handling for Currency and Number Formating was changed. This is now based on jQuery Globalize project.

The Anchor Tag provides also some new attributes. This new attributes allows an improved handling when submitting a form via Anchor Tag. For details please see Issue 849.

Struts2 jQuery Plugin now based on jQuery 1.7 and with support for frozen Columns

jogep — Tue, 13 Mar 2012 21:01:31 +0000

I am happy to announce that the Version 3.3.0 of Struts2 jQuery Plugin is now available. The main change is the switch from jQuery 1.6.4 to the latest version 1.7.1 of the jQuery 1.7.x releases.

This Version includes a lot of library updates and 18 solved Issues. The Handler Functions are now split into two different JavaScript Files. One for the base jQuery AJAX Handling and one for the jQuery UI Tags. This improves the load time in all application which are running without jQuery UI widgets.

The Grid tag is now supporting frozen columns which comes with the latest jqGrid release 4.3.1. Simply add the frozen attribute to your first grid column to enable this feature. Also take a look at the new add and delete buttons in your Navigator when using Edit inline. To enable this buttons set the navigatorInlineEditButtons to true.

 ... frozen="true" .. />

The Struts2 jQuery Plugin provides now two Maven Archetypes for an easy start with Struts2, jQuery and Maven. The first is based on the Struts2 Convention Archetype but with included s2j dependencies. The second is for an easy start with the Grid Plugin. This new Archetypes shrinks the Steps described in my previous post 4 Easy Steps to create a Java based Web Application with Struts2 and jQuery to only one Step.


mvn archetype:generate -B -DgroupId=com.mycompany.mysystem -DartifactId=myWebApp -DarchetypeGroupId=com.jgeppert.struts2.jquery -DarchetypeArtifactId=struts2-jquery-archetype-base -DarchetypeVersion=3.3.0

New Struts2 Bootstrap Plugin released

jogep — Wed, 01 Feb 2012 20:15:15 +0000

I have just released my first GIT based Project at Google Code. Thanks to IntelliJ IDEA for the great GIT Integration.

This Struts2 Bootstrap Plugin is for an easy Integration of Twitter Bootstrap into an Bootstrap based Struts2 Webapp. It provides a Head Tag which loads necessary resources and a new theme for Struts2 Tags. A new Struts2 Bootstrap Plugin Showcase provides a short introduction how to use this Plugin.

Steps to use it in your Project:

1. Add the jar

To use this plugin you need to copy the struts2-bootstrap-plugin.jar into your WEB-INF/lib path. A maven Integration is following soon.

2. Add the Head Tag to your JSP

To load the required CSS Styles and JavaScript Resources you need to add the Head Tag to your html head area like following Example.

<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sb" uri="/struts-bootstrap-tags" %>

 lang="en">
>
    >MyApp Title>
     http-equiv="Content-Type" content="text/html; charset=utf-8"/>
 
    
    
 
    />
>
>
...
>
>

3. Using the Form Tags

Now you are able to use the form theme, simple by adding the theme="bootstrap" attribute to your tag.

     theme="bootstrap"/>
     theme="bootstrap"/>
     theme="bootstrap"/>
 
 
     action="index" enctype="multipart/form-data" theme="bootstrap" cssClass="form-horizontal"
            label="A sample horizontal Form">
        
                label="Name"
                name="name"
                tooltip="Enter your Name here"/>
 
        
                label="Textfield with Error"
                name="error"/>
 
        
                tooltip="Enter your Biography"
                label="Biography"
                name="bio"
                cols="20"
                rows="3"/>
 
        
                tooltip="Choose Your Favourite Color"
                label="Favorite Color"
                list="{'Red', 'Blue', 'Green'}"
                name="favouriteColor"
                emptyOption="true"
                headerKey="None"
                headerValue="None"/>
 
        
                tooltip="Choose your Friends"
                label="Friends"
                list="{'Wes', 'Patrick', 'Jason', 'Jay', 'Toby', 'Rene'}"
                name="friends"/>
 
        
                tooltip="Choose your Best Friend"
                label="Best Friend"
                list="{'Wes', 'Patrick', 'Jason', 'Jay', 'Toby', 'Rene'}"
                name="bestFriend"
                cssErrorClass="foo"/>
 
        
                tooltip="Confirmed that your are Over 18"
                label="Age 18+"
                name="legalAge"/>

Sind Java Frameworks mit Java EE 6 obsolete?

jogep — Mon, 18 Oct 2010 15:09:28 +0000

Matt Raible antwortet in seinem Blog auf die von Cameron McKenzie bei TheServerSide aufgestellte These "Moving from Spring to Java EE 6: The Age of Frameworks is Over" mit einem klaren nein! Interessant fand ich die Aussage das JSF1 und JSF2 meist nur von Buch Autoren, MyFaces Entwicklern oder Java EE Vendors promoted wird, aber die wenigsten Entwickler damit wirklich glücklich sind. Und lieber zu Java Frameworks wie Struts2 oder Spring MVC greifen sollten. Was ich persönlich auch bestätigen kann.

How to parse a JSON Object when using multiSearch for jqGrid with Java

jogep — Sat, 05 Jun 2010 22:42:45 +0000

This is a tutorial that shows how to handle a JSON Object that is received in a Struts2 Action. This Example is based on the Struts2 Grid Showcase for the Struts2 jQuery Plugin with Grid Extension. 1. First we need to enable the Multi Search Feature for the Grid Component.

< sjg :grid 
	id="customerstable" 
	...
	navigatorSearch="true"
	navigatorSearchOptions="{multipleSearch:true}"
	...
>

Now we can use the multiple search feature like this. 2.) After this we need a String property filter in our Struts2 Action.

private String filters;
 
public void setFilters(String filters) {
	this.filters = filters;
}

3.) Now we receive a JSON Object when we use the Search in the Navigator of the Grid. The JSON looks like this example.

{
	"groupOp":"AND",
	"rules":[
		{
			"field":"customernumber",
			"op":"lt",
			"data":"200"
		}
		,
		{
			"field":"country",
			"op":"eq",
			"data":"USA"
		}
		]
}

4.) To work with this, we need to serialize this as a JSONObject.

JSONObject jsonFilter = (JSONObject) JSONSerializer.toJSON( filters );

5.) Now we can get the value from the JSON Object. First we get the parameter groupOp.

String groupOp = jsonFilter.getString("groupOp");
log.debug("groupOp :" + groupOp);

6.) Now we need the rules as JSONArray and the size of this array.

JSONArray rules = jsonFilter.getJSONArray("rules");
int rulesCount = JSONArray.getDimensions(rules)[0];
log.debug("Count Rules :" + rulesCount);

7.) In a simple for-loop we can get the values of the rule.

for (int i = 0; i < rulesCount; i++) {
	JSONObject rule = rules.getJSONObject(i);
	log.debug("field :" + rule.getString("field"));
	log.debug("op :" + rule.getString("op"));
	log.debug("data :" + rule.getString("data"));
}

Now you should be able to use this values to build a custom SQL query or build an hibernate criteria.

The new version 2.1.0 of Struts2 jQuery Plugin is released. With this new version, the plugin loads dependent JavaScript files on demand.
