2、action
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="list">/WEB-INF/pages/workflow/processdefinition_list.jsp</result>
<result name="Pngview" type="stream">
<param name="contentType">image/png</param>
<param name="inputName">ImgSI</param>
</result>
</action>
