My server.xml:

<Context path="/rsglxt" docBase="D:\Users\wind\workspace\rsglxt"
debug="5" reloadable="true" crossContext="true" workDir="D:\Users\wind\workspace\rsglxt\work">
<Resource name="jdbc/rsglxt"
auth="Container"
type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="admin" password="123456"
driverClassName="com.microsoft.sqlserver.jdbc.SQLS erverDriver"
url="jdbc:sqlserver://localhost:1433;DatabaseName=tempdb"/>
</Context>

I have tested connect sqlserver successfully by odbc data source. But I log in from homepage of my java programe, it shows this error.

Make sure you have called close(); method on all variables for which you have used getOutputStream(); in your action class.

This exception is usually triggered by one of two things:
-when you are writing data directly to the output stream in your action, close the stream then Struts forwards to a JSP that needs the output stream
-you attempt to use two forwards in your action. The first forward will close the stream and the second will throw an exception.
This probably doesn't have anything to do with SQLServer, but your first step when debugging should be to eliminate possible variables to isolate the problem. Read our FAQ, HowToAskQuestionsOnJavaRanch, try to narrow down the cause and show us some code.
