这是JAVA代码,, 该sql语句在数据库执行正常..在java端提示没有返回结果集

public String enter(String funcode, String inputStr,
String ExtensionInputStr, String name, String pwd, String path) {
String ss = "";
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
conn = DriverManager.getConnection(path, name, pwd);
String sql = "DECLARE @return_value int,@OutputStr varchar(max),@ExtensionOutputStr varchar(max) EXEC @return_value = [dbo].[ap_callSelfServices] @funcode = ?,@InputStr =?,@ExtensionInputStr = ?,@OutputStr = @OutputStr OUTPUT,@ExtensionOutputStr = @ExtensionOutputStr OUTPUT";
ps = conn.prepareStatement(sql);
ps.setObject(1, funcode);
ps.setObject(2, inputStr);
ps.setObject(3, ExtensionInputStr);
rs = ps.executeQuery();
if (rs.next()) {
ss = rs.getString(1);
}
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return ss;
}
这是报的错..数据库返回的是xml形式,我给转换成字符串了 ..
