1、 jsp乱码问题，需要在首行加上：
<%@ page language="java" contentType="text/html;charset=gb2312" %>
据archive说这样设置在其他地方可能还会出现乱码的，先保证俺的能用。
2、 从tab中读取数据，代码在printstack中显示。
myMap = new MapJ();
myMap.loadMapDefinition("e:/share/test/test.mdf"); //------------for adding a buffer------------------------------------
ArrayList columns = new ArrayList();
//tab表的结构
columns.add("fName");
columns.add("fID");
columns.add("fAddr"); FeatureLayer parkLayer = (FeatureLayer)myMap.getLayers().get("test");
//FeatureSet fs = parkLayer.searchByAttribute(columns,"road",att1,null);
TableInfo ti = parkLayer.getTableInfo();
List allCols = new ArrayList();
System.out.print("Columns: ");
int colCount = ti.getColumnCount();
for ( int i = 0; i < colCount; i++ )
{
String colName = ti.getColumnName(i);
allCols.add(colName);
// Print all of the column names for reference later
System.out.print(colName);
if ( i < colCount - 1 )
{
System.out.print(", ");
}
}
System.out.println(""); //QueryParams qp = new QueryParams();
FeatureSet fs = parkLayer.searchAll(columns, null);
RewindableFeatureSet rfs = new RewindableFeatureSet(fs);
Feature f; // Loop until FeatureSet.getNextFeature() returns null
int featNum = 1;
rfs.rewind();
while ( (f = rfs.getNextFeature()) != null )
{
// Print out all of the Attributes of each Feature
System.out.print("Attributes #" + featNum++ + ": ");
Geometry g = f.getGeometry(); for ( int i = 0; i < colCount; i++ )
{
System.out.print(f.getAttribute(i));
if ( i < colCount - 1 )
{
System.out.print(", ");
}
}
System.out.println("");
f.getAttribute(0).set("hello");
}
fs.dispose();
