Create a "JdbcStoreBinder" class under "org.joget.tutorial" package. Then, extend the class with org.joget.apps.form.model.FormBinder abstract class.
To make it work as a Form Store Binder, we will need to implement org.joget.apps.form.model.FormStoreBinder interface. Then, we need to implement org.joget.apps.form.model.FormStoreElementBinder interface to make this plugin show as a selection in store binder select box and implement org.joget.apps.form.model.FormStoreMultiRowElementBinder interface to list it under the store binder select box of grid element.
Please refer to Form Store Binder Plugin.
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.

package org.joget.tutorial;
import org.joget.apps.app.service.AppPluginUtil;
import org.joget.apps.app.service.AppUtil;
import org.joget.apps.form.model.Element;
import org.joget.apps.form.model.FormBinder;
import org.joget.apps.form.model.FormData;
import org.joget.apps.form.model.FormRowSet;
import org.joget.apps.form.model.FormStoreBinder;
import org.joget.apps.form.model.FormStoreElementBinder;
import org.joget.apps.form.model.FormStoreMultiRowElementBinder;
public class JdbcStoreBinder extends FormBinder implements FormStoreBinder, FormStoreElementBinder, FormStoreMultiRowElementBinder {
private final static String MESSAGE_PATH = "messages/JdbcStoreBinder";
public String getName() {
return "JDBC Store Binder";
}
public String getVersion() {
return "5.0.0";
}
public String getClassName() {
return getClass().getName();
}
public String getLabel() {
//support i18n
return AppPluginUtil.getMessage("org.joget.tutorial.JdbcStoreBinder.pluginLabel", getClassName(), MESSAGE_PATH);
}
public String getDescription() {
//support i18n
return AppPluginUtil.getMessage("org.joget.tutorial.JdbcStoreBinder.pluginDesc", getClassName(), MESSAGE_PATH);
}
public String getPropertyOptions() {
return AppUtil.readPluginResource(getClassName(), "/properties/jdbcStoreBinder.json", null, true, MESSAGE_PATH);
}
public FormRowSet store(Element element, FormRowSet rows, FormData formData) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
} |
Then, we have to do a UI for admin user to provide inputs for our plugin. In getPropertyOptions method, we already specify our Plugin Properties Options definition file is locate at "/properties/jdbcStoreBinder.json". Let us create a directory "resources/properties" under "jdbc_store_binder/src/main" directory. After create the directory, create a file named "jdbcStoreBinder.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.
