HARMONY-948 has a serialized dtd file called transitional401.bdtd. When I try to read it by calling DTD.read(DataInputStream) I get a java.io.EOFException. But, on the other hand, when I create a binary DTD by calling DTDUtilities.create(String) I can get it with succeed.
How can I read transitional401.bdtd file? I used the JRE Harmony 424571 release in GNU/Linux. Thanks, Diego Mercado On 7/28/06, Miguel Montes <[EMAIL PROTECTED]> wrote:

In fact, I was thinking in using your decoder, Stepan, so that's great news.
