Maven Support

Like promised in my previous post, this Plugin is now available as Maven Artifact. 
<dependencies>
    ...
    <dependency>
        <groupId>com.jgeppert.struts2.bootstrap</groupId>
        <artifactId>struts2-bootstrap-plugin</artifactId>
        <version>1.2.0</version>
    </dependency>
    ...
</dependencies>

Extended Showcase

The Showcase includes now more Examples.
  • Example for Vertical Form Layout
  • Example for Inline Form Layout
  • Form Elements with Help Text
  • Textfields with prepended text or appended text
  • An AJAX Example in combination with the Struts jQuery Plugin
Currently only the the SNAPSHOT Version 3.3.0 of Struts2 jQuery Plugin is supported, because Bootstrap requires jquery version 1.7.1 as minimum.

]]> http://www.jgeppert.com/2012/02/version-1-2-0-of-struts2-bootstrap-plugin-released/feed/ 0 New Struts2 Bootstrap Plugin released http://www.jgeppert.com/2012/02/new-struts2-bootstrap-plugin-released/ http://www.jgeppert.com/2012/02/new-struts2-bootstrap-plugin-released/#comments Wed, 01 Feb 2012 20:15:15 +0000 jogep http://www.jgeppert.com/?p=588 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" %>
<!DOCTYPE html>
<html lang="en">
<head>
    <title>MyApp Title</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
 
    <!-- Le HTML5 shim, for IE6-8 support of HTML elements -->
    <!--[if lt IE 9]>
    <script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
    <![endif]-->
 
    <sb:head/>
</head>
<body>
...
</body>
</html>

3. Using the Form Tags

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

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

Da ich das ganze in einer heterogenen Umgebung betreibe, also sowohl Windows als auch Linux (openSuse 11.3), stellt sich natürlich die Frage wie kann ich die Samba Freigaben auch unter Linux nutzen. 1.) Stelle sicher das der cifs Dienst gestartet wird. Starte dazu das Yast Modul Systemdienste (Runlevel), das du unter System findest, und gehe in den Expertenmodus. Aktiviere anschließend den Dienst cifs für die Runlevel 2, 3 und 5. Yast Runlevel Editor - Cifs Dienst 2.) Füge in deinem NAS einen Benutzer hinzu und im öffentlichen Bereich einen Ordner Bilder. Ordner die im öffentlichen Bereich erstellt werden stehen allen Benutzer zur Verfügung. 3.) Erstelle in deinem Home Laufwerk einen Order z.B. MyPictures und einen Ordner MyData. In den Ordner MyData wird das Persönliche Verzeichnis des NAS Benutzers verknüpft und in den Order MyPictures wird ein öffentlicher Ordner Bilder der vorher erstellt wurde verknüpft. 4.) Editiere mit root Berechtigungen die Datei /etc/fstab und füge am ende der Datei folgende Zeile ein. //<NAS IP>/public/Bilder/   /home/<Linux UserID>/MyPictures   cifs   user=<NAS BenutzerID>%<Dein Passwort>,_netdev,uid=johannes,gid=users,utf8=true   0 0 //<NAS IP>/<NAS BenutzerID>/   /home/<Linux UserID>/MyData   cifs   user=<NAS BenutzerID>%<Dein Passwort>,_netdev,uid=johannes,gid=users,utf8=true   0 0 5.)

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. struts2 jquery grid with multiple search 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.]]> http://www.jgeppert.com/2010/06/how-to-parse-a-json-object-when-using-multisearch-for-jqgrid-with-java/feed/ 21 Struts2 jQuery Plugin Version 2.1.0 is released http://www.jgeppert.com/2010/05/struts2-jquery-plugin-version-2-1-0-is-released/ http://www.jgeppert.com/2010/05/struts2-jquery-plugin-version-2-1-0-is-released/#comments Sat, 01 May 2010 20:09:51 +0000 jogep http://www.jgeppert.com/?p=369 Struts2 jQuery Plugin is released. With this new version, the plugin loads dependent JavaScript files on demand. This feature makes the plugin much better extensible for own extensions and  reduces the initial load of the first load of a page. Based on the new structure of the plugin the jqGrid Feature is not longer a part of the core plugin. It is now available as a separate extension of the plugin. There is also a new richtext extension available, that is based on the latest version of popular CKEditor. This allows an  easy integration of the richtext editor in your web application. The Plugin includes now the latest version of jQuery UI 1.8.1, so if you use a custom theme it is recommended to update this in the ThemeRoller. For more informations and the changelog for 1.8.1 please read the blog post from jQuery UI. Changelog:
