是这样的，ssh框架，通过return 字符串跳转页面，action代码如下，注释为生成的tree的部分字符串
addlist = this.service.findAll();
copylist = new ArrayList(Arrays.asList(new Object[addlist.size()]));
Collections.copy(copylist, addlist);
this.tree = this.getAllTree(addlist);
System.out.println(tree);
//<div><script type="text/javascript">d = new dTree('d');d.add(1,-1,' 权限配置','',' 权限配置','','./images/tree01.jpg','./images/tree01.jpg'); ... document.write(d);</script></div>
return SUCCESS;xml配置文件如下：
<!-- 修改角色树形结构权限树 与上面的modifyTypeAndPid相互冲突，选择其一-->
<action name="modifyMoudlesAction" class="RoleAction" method="modifyTypeAndPid">
<result name="success">/systemmanager/modifyPowerTree.jsp</result>
<result name="error">/error.jsp</result>
</action>debug运行到retrun success时没有任何问题，f8以后抛出异常
java.lang.IllegalStateExceptionjsp代码如下：
<div id="treebar" >
${tree}
</div>网上资料说，两个流相冲突了，那该如何解决呢，在线急等，感谢感谢~~ssh异常
