나는 그것을 얻었습니다.
DownloadServiceHandler를 작성하고 save-command의 핸들러에 download-URL이있는 보이지 않는 브라우저를 만들었습니다. 단계별로
모든 작업 단계 :
도구 모음에서 저장 버튼은 plugin.xml에 구성됩니다 : 방법의 postWindowCreate에서

public class DownloadServiceHandler implements IServiceHandler 
{ 
    public void service() throws IOException, ServletException 
    { 
    final String fileName = RWT.getRequest().getParameter("filename"); 
    final byte[] download = getYourFileContent().getBytes(); 
    // Send the file in the response 
    final HttpServletResponse response = RWT.getResponse(); 
    response.setContentType("application/octet-stream"); 
    response.setContentLength(download.length); 
    final String contentDisposition = "attachment; filename=\"" + fileName + "\""; 
    response.setHeader("Content-Disposition", contentDisposition); 
    response.getOutputStream().write(download); 
    } 
} 

:

<extension 
     point="org.eclipse.ui.commands"> 
     <command 
      id="pgui.rcp.command.save" 
      name="Save"> 
     </command> 
    </extension> 
    <extension 
     point="org.eclipse.ui.menus"> 
     <menuContribution 
      allPopups="false" 
      locationURI="toolbar:org.eclipse.ui.main.toolbar"> 
     <toolbar 
       id="pgui.rcp.toolbar1"> 
      <command 
        commandId="pgui.rcp.command.save" 
        icon="icons/filesave_16.png" 
        id="pgui.rcp.button.save" 
        style="push" 
      </command> 
     </toolbar> 
     </menuContribution> 
    </extension> 
    <extension 
     point="org.eclipse.ui.handlers"> 
     <handler 
      class="pgui.handler.SaveHandler" 
      commandId="pgui.rcp.command.save"> 
     </handler> 
    </extension> 

은 내가 DownloadServiceHandler를 생성 ApplicationWorkbenchWindowAdvisor에 DownloadServiceHandler를 등록했습니다.

private void registerDownloadHandler() 
    { 
    final IServiceManager manager = RWT.getServiceManager(); 
    final IServiceHandler handler = new DownloadServiceHandler(); 
    manager.registerServiceHandler("downloadServiceHandler", handler); 
    } 

SaveHandler의 execute-method에서 보이지 않는 브라우저를 만들고 URL과 파일 이름 및 등록 된 DownloadServiceHandler를 설정합니다.

final Browser browser = new Browser(shell, SWT.NONE); 
    browser.setSize(0, 0); 
    browser.setUrl(createDownloadUrl(fileName)); 
     . 
     . 
    private String createDownloadUrl(final String fileName) 
    { 
    final StringBuilder url = new StringBuilder(); 
    url.append(RWT.getRequest().getContextPath()); 
    url.append(RWT.getRequest().getServletPath()); 
    url.append("?"); 
    url.append(IServiceHandler.REQUEST_PARAM); 
    url.append("=downloadServiceHandler"); 
    url.append("&filename="); 
    url.append(fileName); 
    return RWT.getResponse().encodeURL(url.toString()); 
    }
