JSP Error: Only a type can be imported. package.class resolves to a package [duplicate]

my project is develop website using JSP. In this project, the JSP file will call a function from my java file.

Here is how I import my java file:

<%@ page import="java.sql.*,java.util.*,de.fraport.mobileformular.CreateEngine,org.activiti.engine.*,org.activiti.engine.runtime.*"%> 

Then, here is how I call my method:

<% //deploy process from activiti CreateEngine ce = new CreateEngine(); %> 

But, I don't know why, when I load above page, it will generate following error:

FYI: this web application running on Tomcat 7 and connected to Activiti Workflow Engine.

Thanks for your help.

Edited:

Here is the deployed class:

package de.fraport.mobileformular; import org.activiti.engine.*; import org.activiti.engine.runtime.*; public class CreateEngine { //set global variable ProcessEngine processEngine; RepositoryService repositoryService; RuntimeService runtimeService; ProcessInstance processInstance; //method for deploying and start process public void deployProcess() { processEngine = ProcessEngines.getDefaultProcessEngine(); repositoryService = processEngine.getRepositoryService(); repositoryService.createDeployment() .addClasspathResource("accidentForm.bpmn20.xml") .deploy(); runtimeService = processEngine.getRuntimeService(); processInstance = runtimeService.startProcessInstanceByKey("accidentForm");; } }
