how to export data

[Dhirendra Kulkarni]

Hi all,   Iam trying to export data from oracle database for particular user through Ant. my build.xml is   <target name="exptest" >     <sql       driver="oracle.jdbc.driver.OracleDriver"       url="jdbc:oracle:thin:@armada:1521:wind"       userid="wtadmin"       password="wtadmin"       src=""       print="yes"     />   </target>   and statement in data.sql file is   exp file='test.dmp'   iam getting error saying that it is invalid statement. Actually if run this command in DOS   exp wtadmin/wtadmin file=test.dmp   it is successfully exporting the database. Also if i type same command in sqlplus, then also iam getting invalid statement. So how do i export data. Please help   Thanks DK
