BeanShell is a small, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax. So, using BeanShell Plugin, you can type in valid Java codes in plugin configuration, and the statements will be executed when the plugin is triggered. No compilation cycle is needed.
The script can be composed of:
Set value to a workflow variable
import org.joget.workflow.model.service.*;
WorkflowManager wm = (WorkflowManager) pluginManager.getBean("workflowManager");
wm.activityVariable(workflowAssignment.getActivityId(), "variableId", "variableValue");

Execute SQL statement through JDBC
import java.sql.*;
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql://localhost/wflowdb?useUnicode=true&characterEncoding=UTF-8", "root", "root");
if(!con.isClosed())
{ System.out.println("Successfully connected to MySQL server using TCP/IP..."); PreparedStatement stmt = con.createStatement(); stmt.executeUpdate("UPDATE formdata_simpleflow set c_status='#assignment.activityId#' WHERE processId='#assignment.processId#'"); }
} catch(Exception e)
{ System.err.println("Exception: " + e.getMessage()); }
finally {
try
{ if(con != null) con.close(); }
catch(SQLException e) {}
}

A participant type plugin should return a collection of usernames. In the participant plugin there are two context variables available for the script to use :
A Beanshell Participant Type Plugin returning one Participant
import java.util.ArrayList;
a = new ArrayList();
a.add("jack"); // one username
return a;

Activity tool type plugin is a plugin that will be executed when workflow reached a System Tool activity. System Tool activities must be placed in the workflow diagram, and then the Beanshell plugin configured in the Process's Activity Mapping for this to work. In this plugin there are two context variables available for the script to use :
import java.util.ArrayList;
import java.util.logging.Logger;
import org.joget.plugin.base.PluginManager;
import java.util.logging.FileHandler;
import org.joget.workflow.model.service.WorkflowManager;
import org.joget.form.model.service.FormManager;
import org.joget.form.model.Form;
FormManager formManager = (FormManager) pluginManager.getBean("formManager");
processId = workflowAssignment.getProcessId();
Form form = formManager.loadDynamicFormByProcessId("T01", processId); // in this example, form's table is T01
formData = form.getCustomProperties();
formData.put("c_columnname","new value"); // the form data field to be set is columnname
form.setCustomProperties(formData);
formManager.saveForm(form);
