我想把自己寫的程序實現為Eclipse插件,
當運行選擇run->org.eclipse.ui.ide.workbench是可以正常運行
但當我我把項目打包放到了plugins下包名字為helloworld.jar
運行的時候就遇到錯誤了,請高手指點,這個問題該怎么解決。謝謝

下面是XML文件

*********************************************************************
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
<plugin
 id="com.yangfei.examples.helloworld"
 name="Hello World Plugin"
 version="1.0.0">
 <requires>
  <import plugin="org.eclipse.ui" />
 </requires>
 <runtime>
  <library name="helloworld.jar" />
 </runtime>
 <extension point="org.eclipse.ui.views">
  <category id="com.yangfei.examples.helloworld.hello" name="Hello" />
  <view id="com.yangfei.examples.helloworld.HelloWorldView"
  name="Hello Greetings"
  category="com.yangfei.examples.helloworld.hello"
  class="com.yangfei.examples.helloworld.HelloWorldView" />
 </extension>
</plugin>
*********************************************************************

這斷HelloWorldView.java的代碼

package com.yangfei.examples.helloworld;

import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.SWT;
import org.eclipse.ui.part.ViewPart;

public class HelloWorldView extends ViewPart {
 Label label;
 public HelloWorldView() {
 }

 public void createPartControl(Composite parent) {
  label = new Label(parent, SWT.WRAP);
  label.setText("Hello World");
 }
 public void setFocus() {
 }

}

windows->show  View->other->Hello->Hello Greetings 時就遇到了錯誤
錯誤信息如下:
