如何在jsp中显示shark的流程图

Answer 1

1、写一个servlet,将流程在web页面上以图形的方式显示。代码如下：
package com.paiao.shark;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.io.PrintStream;
import javax.imageio.ImageIO;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.*;
import org.enhydra.shark.Shark;
import org.enhydra.shark.api.client.wfservice.AdminInterface;
import org.enhydra.shark.api.client.wfservice.PackageAdministration;
import org.enhydra.shark.api.client.wfbase.*;
import java.io.*;
import org.enhydra.jawe.*;
import org.enhydra.jawe.graph.Process;
import org.enhydra.jawe.xml.elements.Package;
import org.enhydra.jawe.xml.elements.WorkflowProcess;
import
