我也补个问题，如何将上传文件通过SQL语句的形式存入数据库哪？
Connection con=conPDM.getConn();
PreparedStatement pstmt=con.prepareStatement(strSQLAdd);
for(int i=0;i<mySmartUpload.getFiles().getCount();i++){
java.io.File file=mySmartUpload.getFiles().getFile(i);
FileInputStream fis = new FileInputStream(file);
pstmt.setBinaryStream(i+1,fis,file.getSize() );
}//end for(int i=0;...为pstmt设置参数完成
pstmt.executeUpdate();

这样不太对呀
