In this tutorial, we will following the guideline of developing a plugin to develop our Gantt Chart Userview Menu plugin. Please also refer to the very first tutorial How to develop a Bean Shell Hash Variable for more details steps.

...

By referring to the library demo, we can quickly come out a static HTML page like the picture below. As this is a Joget plugin tutorial, we will not go into the detail on coding the static HTML page. You can refer to static.zip. We will expect our userview page can display our collected data as the static HTML page.

5. Is there any resources/API that can be reuse?

To develop the PDF Download Datalist Action plugin, we can reuse the methods in FormPdfUtil to generate a form as PDF. We can also refer to the source code of the Datalist Form Data Delete Action plugin as well. Other than that, we can refer to the Export Form Email Tool on what kind of plugin properties options we can provide in the plugin as the Export Form Email Tool are using the methods in FormPdfUtil as well.

6. Prepare your development environment

If you are not familiar with FreeMaker syntax, you should have a look on their document before proceed.

6. Prepare your development environment

We need to always have our Joget Workflow Source Code ready and builded by following this guideline.We need to always have our Joget Workflow Source Code ready and builded by following this guideline. 

The following of this tutorial is prepared with a Macbook Pro and Joget Source Code version 5.0.0. Please refer to Guideline of for developing a plugin for other platform command.

...

We should get "BUILD SUCCESS" message shown in our terminal and a "gantt_cahrtchart_menu" folder created in "plugins" folder.

Open the maven project with your favour favourite IDE. I will be using NetBeans.

package org.joget.tutorial;
 
import org.joget.apps.app.service.AppPluginUtil;
import org.joget.apps.userview.model.UserviewMenu;
 
public class GanttChartMenu extends UserviewMenu {
    
    private final static String MESSAGE_PATH = "messages/GanttChartMenu";
 
    public String getName() {
        return "Gantt Chart Menu";
    }
    public String getVersion() {
        return "5.0.0";
    }
    
    public String getClassName() {
        return getClass().getName();
    }
    
    public String getLabel() {
        //support i18n
        return AppPluginUtil.getMessage("org.joget.tutorial.GanttChartMenu.pluginLabel", getClassName(), MESSAGE_PATH);
    }
    
    public String getDescription() {
        //support i18n
        return AppPluginUtil.getMessage("org.joget.tutorial.GanttChartMenu.pluginDesc", getClassName(), MESSAGE_PATH);
    }
 
    public String getPropertyOptions() {
        return AppUtil.readPluginResource(getClassName(), "/properties/ganttChartMenu.json", null, true, MESSAGE_PATH);
    }
 
    @Override
    public String getCategory() {
        return "Marketplace";
    }
    @Override
    public String getIcon() {
        //sorry, i am reuse the icon of other plugin here
        return "/plugin/org.joget.apps.userview.lib.HtmlPage/images/grid_icon.gif";
    }
    
    @Override
    public boolean isHomePageSupported() {
        return true; // Can use as first page of the userview
    }
    
    @Override
    public String getDecoratedMenu() {
        return null; // using default
    }
 
    @Override
    public String getRenderPage() {
        throw new UnsupportedOperationException("Not supported yet."); 
    }
}

Then, we have to do a UI for admin user to provide inputs for our plugin. In getPropertyOptions method, we already specify have already specifed our Plugin Properties Options definition file is locate at "/properties/ganttChartMenu.json". Let us create a directory "resources/properties" under "gantt_chart_menu/src/main" directory. After create the directory, create a file named "ganttChartMenu.json" in the "properties" folder.

In the properties definition options file, we will need to provide options as below. Please note that we can use "@@message.key@@" syntax to support i18n in our properties options.

Code Block
languagejs
 

After done the properties option to collect input, we can work on the main method of the plugin which is getRenderPage method.

Code Block
languagejava
 

c. Manage the dependency libraries of your plugin

Our plugin is using javax.servlet.http.HttpServletRequest and javax.servlet.http.HttpServletResponse class, so we will need to add jsp-api library to our POM file.

Code Block
languagexml
<!-- Change plugin specific dependencies here -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.0</version>
</dependency>
<!-- End change plugin specific dependencies here -->

d. Make your plugin internationalization (i18n) ready

We are using i18n message key in getLabel and getDescription method. We also used i18n message key in our properties options definition as well. So, we will need to create a message resource bundle properties file for our plugin.

Create directory "resources/messages" under "gantt_chart_menu/src/main" directory. Then, create a "GanttChartMenu.properties" file in the folder. In the properties file, let add all the message keys and its label as below.

Code Block
 

e. Register your plugin to Felix Framework

We will have to register our plugin class in Activator class (Auto generated in the same class package) to tell Felix Framework that this is a plugin.

Code Block
languagejava
    public void start(BundleContext context) {
        registrationList = new ArrayList<ServiceRegistration>();
        //Register plugin here
        registrationList.add(context.registerService(GanttChartMenu.class.getName(), new GanttChartMenu(), null));
    }

 

f. Build it and testing 

Let build our plugin. Once the building process is done, we will found a "gantt_chart_menu-5.0.0.jar" file is created under "gantt_chart_menu/target" directory.

Then, let upload the plugin jar to Manage Plugins. After upload the jar file, double check the plugin is uploaded and activated correctly.

        mode : 'html'
    }]
}]

After done the properties option to collect input, we can work on the main method of the plugin which is getRenderPage method. Normally, what I will do before go into detail to populate the data to the view, I will first put the static content for the getRenderPage to build and test the plugin first. It everything is fine, then only we try to add data to the view.

Code Block
languagejava
    @Override
    public String getRenderPage() {
        Map model = new HashMap();
        model.put("request", getRequestParameters());
        model.put("element", this);
        
        PluginManager pluginManager = (PluginManager)AppUtil.getApplicationContext().getBean("pluginManager");
        String content = pluginManager.getPluginFreeMarkerTemplate(model, getClass().getName(), "/templates/ganttChart.ftl", null);
        return content;
    }

Then, let us create a template file locate at "/templates/ganttChart.ftl". Let us create a directory "resources/templates" under "gantt_chart_menu/src/main" directory. After create the directory, create a file named "ganttChartMenu.json" in the "templates" folder.

Put the static HTML we create previously into the template file as below. Remember to put all the dependencies javascript library and images under "gantt_chart_menu/src/main/resources/resources" and change the url as below accordingly. You project directory should look like the image below now.

             });
         });

Now, for testing purpose, we can skip to c. Manage the dependency libraries of your plugin, d. Make your plugin internationalization (i18n) readye. Register your plugin to Felix Framework and f. Build it and testing then continue the below after testing it. You will get something similar to below in your userview.

After verify the static HTML is working in our plugin, we can further enhance it by adding data to the view. Now, modify your getRenderPage method and ganttChart.ftl template as below.

Code Block
languagejava
    @Override
    public String getRenderPage() {
        Map model = new HashMap();

c. Manage the dependency libraries of your plugin

Our plugin is using some libraries, we have to add all of them to our POM file.

Code Block
languagexml
        <!-- Change plugin specific dependencies here -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.0</version>
        </dependency>
        <dependency>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
            <version>20080701</version>
        </dependency>
        <dependency>
            <groupId>displaytag</groupId>
            <artifactId>displaytag</artifactId>
            <version>1.2</version>
            <exclusions>
                <exclusion>
                    <artifactId>slf4j-api</artifactId>
                    <groupId>org.slf4j</groupId>
                </exclusion>

                </exclusion>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-log4j12</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <!-- End change plugin specific dependencies here -->

d. Make your plugin internationalization (i18n) ready

We are using i18n message key in getLabel and getDescription method. We also used i18n message key in our properties options definition as well. So, we will need to create a message resource bundle properties file for our plugin.

Create directory "resources/messages" under "gantt_chart_menu/src/main" directory. Then, create a "GanttChartMenu.properties" file in the folder. In the properties file, let add all the message keys and its label as below.

Code Block
org.joget.tutorial.GanttChartMenu.pluginLabel=Gantt Chart Menu
org.joget.tutorial.GanttChartMenu.pluginDesc=Display data in a Gantt Chart view
userview.ganttchart.config=Configure Gantt Chart Menu
userview.ganttchart.customId=Custom ID
userview.ganttchart.invalidId=Only alpha-numeric and underscore characters allowed
userview.ganttchart.label=Label
userview.ganttchart.title=Page Title
userview.ganttchart.binder=Data Binder
userview.ganttchart.mapping=Column to Data Mappings
userview.ganttchart.mapping.category=Category (column ID)
userview.ganttchart.mapping.task=Task (column ID)
userview.ganttchart.mapping.activity=Activity (column ID)
userview.ganttchart.mapping.fromDate=Activity From Date (column ID)
userview.ganttchart.mapping.toDate=Activity To Date (column ID)
userview.ganttchart.mapping.dateFormat=Date format for Activity From/To Date
userview.ganttchart.mapping.taskId=Task Id (column ID)
userview.ganttchart.mapping.cssClass=Status (column ID, use as CSS class for styling)
userview.ganttchart.advanced=Advanced
userview.ganttchart.itemsPerPage=Item pre page
userview.ganttchart.navigate=Navigator
userview.ganttchart.navigate.buttons=Buttons
userview.ganttchart.navigate.scroll=Scroll
userview.ganttchart.scale=Default Scale
userview.ganttchart.scale.hours=Hours
userview.ganttchart.scale.days=Days
userview.ganttchart.scale.weeks=Weeks
userview.ganttchart.scale.months=Months
userview.ganttchart.maxScale=Maximum Scale
userview.ganttchart.minScale=Minimum Scale
userview.ganttchart.useCookie=Use cookie for storing chart states
userview.ganttchart.scrollToToday=Auto scroll to today after rendered
userview.ganttchart.onItemClick=On Item Clicked Event (Javascript)
userview.ganttchart.onAddClick=On Empty Space Clicked Event (Javascript)
userview.ganttchart.onRender=On Rendered Event (Javascript)
userview.ganttchart.customHeader=Custom Header (HTML)
userview.ganttchart.customFooter=Custom Footer (HTML)
userview.ganttChart.months.label="January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"
userview.ganttChart.dow.label="S", "M", "T", "W", "T", "F", "S"
userview.ganttChart.waitText=Loading...

e. Register your plugin to Felix Framework

We will have to register our plugin class in Activator class (Auto generated in the same class package) to tell Felix Framework that this is a plugin.

Code Block
languagejava
    public void start(BundleContext context) {
        registrationList = new ArrayList<ServiceRegistration>();
        //Register plugin here
        registrationList.add(context.registerService(GanttChartMenu.class.getName(), new GanttChartMenu(), null));
    }

f. Build it and testing 

Let build our plugin. Once the building process is done, we will found a "gantt_chart_menu-5.0.0.jar" file is created under "gantt_chart_menu/target" directory.

Then, let upload the plugin jar to Manage Plugins. After upload the jar file, double check the plugin is uploaded and activated correctly.

Image Added

Open a userview, you will see the new plugin is added under "Marketplace". Drag it to one of your Userview Category.

Image Added

Edit the properties of the Gantt Chart Menu.

Image Added

I selected "Form Data Binder" as "Data Binder" for testing. Fill all the mappings to corresponding Field Id/Column Id.

Image Added

Configure binder.

Image Added

Advanced setting to configure the gantt chart.

Image Added

Writing some css styling in "Custom Footer (HTML)" option to give different colors for different status.

Image Added

Populate some data to the form for testing.

Image Added

The end result.

8. Take a step further, share it or sell it

You can download the source code from gantt_chart_menu.zip.

The test app for this tutorial is APP_testGanttChart-1-20151106194035.jwa.

To download the ready-to-use plugin jar, please find it in http://marketplace.joget.org/.
