急，用java读取sqlserver中的image！

[tangjr]

请问各位高人，如何在sqlserver中读取一个30兆左右的image（oa_data），如果用sql语句查询image字段直接就内存溢出了
select oa_data from oa_wffiles where id=?;
pstmt.setString(1,id);
执行下面一句话已经出错了，更别提读取了，可能java虚拟机承受不了把几十兆的数据一次加载到内存里：
ResultSet rs = pstmt.executeQuery();
大家有什么解决办法
出错信息如下：
Could not execute query

while(rs.next())
{
ServletOutputStream sout = response.getOutputStream();
InputStream in = rs.getBinaryStream(1);
byte b[] = new byte[0x7a120];
for(int i = in.read(b); i != -1;)
{
sout.write(b);
in.read(b);
}
sout.flush();
sout.close();
}

ResultSet rs = pstmt.executeQuery();
中的rs还没查询出来呢，就出错了，更别提
while(rs.next())
请继续指点
