In this tutorial, we will following the guideline of developing a plugin to develop our Form Submission Statistics Generator. Please also refer to the very first tutorial 如何开发一个Bean Shell Hash Variable插件 for more details steps.
1. What is the problem?
We have 2 SQL Chart menus (the queries used are dependent on MySQL) to show form data submission statistics and this 2 menus always need to replicate for different form.
2. What is your idea to solve the problem?
We can develop a Generator 插件 to ease the process to replicate the 2 SQL Chart menus for other forms.
3. What is the input needed for your plugin?
To develop a Generator Plugin for our 2 SQL Chart menus, we can consider to provide the following as input.
- Userview ID : Which userview to add this 2 SQL menus
- Some option for label change in Category label, Menu label, and Chart label
4. What is the output and expected outcome of your plugin?
2 SQL Chart menus will be added to the selected userview under a new category. One of the menu will show the monthly submission chart and another one will show the daily submission chart based on the year and month filter.
5. Is there any resources/API that can be reuse?
First, we can do build our 2 SQL Chart menus in one of the existing userview. Then, copy the JSON definition of the category which contains our 2 SQL Chart menus form the "ADVANCED: JSON Definition" on the bottom of the Userview Builder.
We will get our JSON definition of the category as following. Please note that the queries used in the 2 SQL Chart menus are dependent on MySQL database.

"customFooter": "",
"datasource": "default",

}
}]
}
After that, we can utilize the GeneratorUtil to add the category JSON definition to our selected userview JSON definition.
6. Prepare your development environment
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 如何开发插件 for other platform command.
Let said our folder directory as following.
- Home
- joget
- plugins
- jw-community
-5.0.0
The "plugins" directory is the folder we will create and store all our plugins and the "jw-community" directory is where the Joget Workflow Source code stored.
Run the following command to create a maven project in "plugins" directory.
cd joget/plugins/ ~/joget/jw-community/5.0.0/wflow-plugin-archetype/create-plugin.sh org.joget.tutorial form_submission_statistics_generator 5.0.0
Then, the shell script will ask us to key in a version for your plugin and ask us for confirmation before generate the maven project.
Define value for property 'version': 1.0-SNAPSHOT: : 5.0.0 [INFO] Using property: package = org.joget.tutorial Confirm properties configuration: groupId: org.joget.tutorial artifactId: form_submission_statistics_generator version: 5.0.0 package: org.joget.tutorial Y: : y
We should get "BUILD SUCCESS" message shown in our terminal and a "form_submission_statistics_generator" folder created in "plugins" folder.
Open the maven project with your favour IDE. I will be using NetBeans.
7. Just code it!
a. Extending the abstract class of a plugin type
Create a "FormSubmissionStatisticsGenerator" class under "org.joget.tutorial" package. Then, extend the class with org.joget.apps.generator.model.GeneratorPlugin abstract class. Please refer to Generator 插件.
b. Implement all the abstract methods
As usual, we have to implement all the abstract methods. We will using AppPluginUtil.getMessage method to support i18n and using constant variable MESSAGE_PATH for message resource bundle directory.
Then, we have to do a UI for admin user to provide inputs for our plugin. In getPropertyOptions method, we already specify our 插件属性选项与配置 definition file is locate at "/properties/formSubmissionStatisticsGenerator.json". Let us create a directory "resources/properties" under "form_submission_statistics_generator/src/main" directory. After create the directory, create a file named "formSubmissionStatisticsGenerator.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.

}]
In the plugin properties option, you may notice we are using "[default_userviewId]" in "userviewId" property. We will use the "[formName]" and "[formId]" in some properties as well. So, we will need to modify the getPropertyOptions method to cater for this values.
public String getPropertyOptions() {
String options = AppUtil.readPluginResource(getClassName(), "/properties/formSubmissionStatisticsGenerator.json", null, true, MESSAGE_PATH);
//populate value like [formName] and [formId]
options = GeneratorUtil.populateFormMeta(options, getFormId(), getAppDefinition());
//populate value of [default_userviewId]
options = options.replace("[default_userviewId]", GeneratorUtil.getFirstAvailableUserviewId(getAppDefinition()));
return options;
}
Once we done the properties option to collect input, we can work on the main method of the plugin which is format method.
@Override
public GeneratorResult generate() {
GeneratorResult result = new GeneratorResult();
AppDefinition appDef = getAppDefinition();
try {
//get userview
UserviewDefinitionDao userviewDefinitionDao = (UserviewDefinitionDao) AppUtil.getApplicationContext().getBean("userviewDefinitionDao");
UserviewDefinition userviewDef = null;
String json = null;
String userviewId = getPropertyString("userviewId");
String userviewName;
String userviewDesc;
if (userviewId != null && !userviewId.isEmpty()) {
userviewDef = userviewDefinitionDao.loadById(userviewId, appDef);
}
if (userviewDef != null) {
userviewName = userviewDef.getName();
userviewDesc = userviewDef.getDescription();
json = userviewDef.getJson();
} else {
userviewId = getPropertyString("userviewNewId");
int count = 0;
while (isExist(userviewId, userviewDefinitionDao)) {
count++;
userviewId = userviewId + count;
}
userviewName = getPropertyString("userviewName");
userviewDesc = getPropertyString("userviewDesc");
}
if (json == null || json.isEmpty()) {
//create a new userview json
json = GeneratorUtil.createNewUserviewJson(userviewId, userviewName, userviewDesc);
}
//add the category json to userview json
json = GeneratorUtil.addCategoryJsonToUserviewJson(getCategoryJson(appDef), json);
//Store the userview json
if (userviewDef != null) {
userviewDef.setJson(json);
userviewDefinitionDao.update(userviewDef);
}else {
userviewDef = new UserviewDefinition();
userviewDef.setJson(json);
userviewDef.setId(userviewId);
userviewDef.setName(userviewName);
userviewDef.setAppDefinition(appDef);
userviewDefinitionDao.add(userviewDef);
//Set current published version
final AppDefinition currentAppDef = appDef;
TransactionTemplate transactionTemplate = (TransactionTemplate)AppUtil.getApplicationContext().getBean("transactionTemplate");
transactionTemplate.execute(new TransactionCallback<Object>() {
public Object doInTransaction(TransactionStatus ts) {
AppService appService = (AppService)AppUtil.getApplicationContext().getBean("appService");
appService.publishApp(currentAppDef.getId(), currentAppDef.getVersion().toString());
return null;
}
});
}
//show message to continue edit
String editLink = WorkflowUtil.getHttpServletRequest().getContextPath() + "/web/console/app/"+appDef.getAppId()+"/"+appDef.getVersion()+"/userview/builder/"+userviewId;
String msg = AppPluginUtil.getMessage("generator.formSubmissionStatistics.msg.success", getClassName(), MESSAGE_PATH);
msg = msg.replace("[url]", editLink);
result.setMessage(msg);
} catch (Exception e) {
result.setError(true);
result.setMessage(AppPluginUtil.getMessage("generator.formSubmissionStatistics.msg.error", getClassName(), MESSAGE_PATH));
LogUtil.error(getClassName(), e, "Not able to generate the menus");
}
return result;
}

In the getCategoryJson method, we will retrieve the category JSON definition form "/resources/category.json" file. Let us create a directory "resources/resources" under "form_submission_statistics_generator/src/main" directory. After create the directory, create a file named "category.json" in the "resources" folder. Then, copy the category JSON definition we created previously and paste it inside this file. We will need to replace some of the hardcoded value as variable and remember to escape those existing "%" to "%%" as the AppUtil.readPluginResource using String.format for injects value into the file.

}
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.
<!-- 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.

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.
public void start(BundleContext context) {
registrationList = new ArrayList<ServiceRegistration>();
//Register plugin here
registrationList.add(context.registerService(FormSubmissionStatisticsGenerator.class.getName(), new FormSubmissionStatisticsGenerator(), null));
}
f. Build it and testing
Let build our plugin. Once the building process is done, we will found a "form_submission_statistics_generator-5.0.0.jar" file is created under "form_submission_statistics_generator/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.
Now, we can open one for our form in Form Builder for testing the generator. Click on the "Generate App" button on right top of the Form Builder. Please refer to Generate App.
Let us check the properties page for "Advanced Generator".
