eclipse RCP 根据输入内容，将内容显示在编辑区中

将输入流内容显示在 eclipse rcp编辑区内，输入流的内容从wsdlurl中获取
String wsdlUrl = "http://fy.webxml.com.cn/webservices/EnglishChinese.asmx?wsdl";
		InputStream inputStream = null;
					
		IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
		if (page != null) {
			try {
				inputStream = getUrlInputStream(wsdlUrl);
				IStorage storage = new WsdlStorage(inputStream,serviceName);
				IStorageEditorInput input = new WsdlEditorInput(storage);
				page.openEditor(input, TextEditor.ID);
			 } catch (Exception e) {
				// TODO: handle exception
				e.printStackTrace();
			}
		}
getUrlInputStream 方法
/**
	 * 根据wsdlurl,返回网页内容
	 * @param wsdlUrl
	 * @return
	 */
	public static InputStream getUrlInputStream(String wsdlUrl) {
		InputStream inputStream = null;
		ByteArrayOutputStream bos = new ByteArrayOutputStream();//定义字符数组输出流对象
