[求助]两个问题：等值线和标注（急，达人们来救命啊）

<P>arcims９，使用imageserver＋htmlviewer，没有用sde，地图属性数据放在dbf中．
1、等值线：
用来画等值线的数据在一个sqlserver里，如何将其与地图文件相关联？
需要在web页中生成等值线，要怎么做？

2、lable
要在地图上显示label，可是我写了xml发送以后没有反应以下是代码
function showLabel(){
var theString="";
theString += "<ARCXML version='1.1'>\n";
theString += "<REQUEST>\n";
theString += "<GET_IMAGE>\n";
theString += "<PROPERTIES>\n";
theString += "<ENVELOPE minx='"+forceComma(eLeft)+"' miny='"+forceComma(eBottom)+"' maxx='"+forceComma(eRight)+"' maxy='"+forceComma(eTop)+"' />\n";
theString += "</PROPERTIES>\n";
theString += " <LAYER type='featureclass' name='报汛站_font_point' visible='true' id='8'>\n";
theString += " <DATASET name='报汛站_font_point' type='point' workspace='shp_ws-0' />\n";
theString += " <GROUPRENDERER>\n";
theString += " <SIMPLELABELRENDERER field='stnm' labelpriorities='2,1,2,4,5,3,2,4'>\n";
theString += " <TEXTSYMBOL font='Arial' fontstyle='regular' fontsize='10' />\n";
theString += " </SIMPLELABELRENDERER>\n";
theString += " <SIMPLERENDERER>\n";
theString += " <SIMPLEMARKERSYMBOL color='255,0,255' width='8' />\n";
theString += " </SIMPLERENDERER>\n";
theString += " </GROUPRENDERER>\n";
theString += " </LAYER>\n";
theString += "</GET_IMAGE>\n";
theString += "</REQUEST>\n";
theString += "</ARCXML>\n";
sendToServer(imsURL,theString,1);
}
这样写有什么问题么？</P>
<P>我也试过在writexml（）里加</P>
<P>if(showLabel){
  theString += "<LAYER type='featureclass' name='报汛站_font_point' visible='true' id='8'>\n";
  theString += "<DATASET name='报汛站_font_point' type='point' workspace='shp_ws-0' />\n";
  theString += "<GROUPRENDERER>\n";
  theString += "<SIMPLELABELRENDERER field='stnm' labelpriorities='2,1,2,4,5,3,2,4'>\n";
  theString += "<TEXTSYMBOL font='Arial' fontstyle='regular' fontsize='10' />\n";
  theString += "</SIMPLELABELRENDERER>\n";
  theString += "<SIMPLERENDERER>\n";
  theString += "<SIMPLEMARKERSYMBOL color='255,0,255' width='8' />\n";
  theString += "</SIMPLERENDERER>\n";
  theString += "</GROUPRENDERER>\n";
  theString += "</LAYER>\n";
}</P>
<P>然后在外面设置showLabel后sendMapXml发送，可一样没用．．．．，到底我该怎么办呀</P>

<P>只有先提取坐标数据，生成图形再加载吧，</P><P>arcims好象编辑功能不强哦，具体偶也没做过，帮你顶住，听楼下的了</P>
