xloadtree Demo本地使用问题

xloadtree的Demo可以从下载，并有usage,api...

将xloadtree的Demo直接放置到Tomcat的Webapps目录下，不能正确显示，总显示“Error Load tree.xml”，一步步对问题进行了跟踪，找到了问题的所在。问题在于XmlHttp使用了responseXML，返回的消息必须是xml，更准确的说是必须能够被识别为xml，要做到这点其实很简单，只要设置ContentType="test/xml"。

我的做法是对xml用jsp进行了包装：

tree.xml
tree.jsp	<%  response.setContentType("text/xml");  out.println(" " + " " + " " + " " + " " + " " + " " + " " + " " + " " + ""); %>

tree1.xml	icon="images/xp/folder.png"/>    icon="images/xp/folder.png"/>                                         icon="http://webfx.eae.net/images/favicon.gif"/>
tree1.jsp	<%  response.setContentType("text/xml");  out.println(" " + " " + " " + " " + " " icon="images/xp/folder.png"/> " + " " icon="images/xp/folder.png"/> " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " icon=" ">http://webfx.eae.net/images/favicon.gif"/> " + ""); %>

tree2.xml
tree2.jsp	<%  response.setContentType("text/xml");  out.println(" " + " " + " " + " " + " " + " " + " " + " " + " " + ""); %>

emptytree.xml
emptytree.jsp	<%  response.setContentType("text/xml");  out.println(" " +     ""); %>

这样就能够正确的显示树图了，这种方法比较适合动态的通过程序获取树图。

还有种比较彻底的办法，更改xloadtree关于xmlhttp的部分。
