public String Pngview() {
InputStream ImgSI= repositoryService.getProcessDiagram(id);
ActionContext.getContext().getValueStack().set("ImgSI",ImgSI);
return "Pngview";
}
3、struts.xml
<action name="processDefinitionAction_*" class="com.dong.bos.web.action.ProcessDefinitionAction" method="{1}">

<result name="Pngview" type="stream">
