Hello Mark, Dennis Another option for compressing XML is WBXML:
http://www.w3.org/TR/wbxml/ Although it's normally used for WML, it's not restricted to WML and could be used for other XML. regards Mark Lines-Davies -----Original Message----- From: Dennis Sosnoski [mailto:[EMAIL PROTECTED] Sent: 18 June 2002 02:08 To: [EMAIL PROTECTED] Subject: Re: Passing large XML Document object via RMI Hi Mark, The best way to deal with this is probably to pass the document as text. Java serialization is designed to handle graphs of objects, but the tree structure of XML document representations (lots of very small objects, none reused) gives it conniptions. The text representation of the document is both smaller than the Java serialized form and faster to process. For some actual figures see http://www.sosnoski.com/opensrc/xmlbench/results.html#java-serial I've got a project I started last year to build a more efficient representation for transferring XML documents, described at http://www.sosnoski.com/opensrc/xmls/index.html. This still looks good, but I haven't carried through on building other adapters and extending the format. A DOM adapter should be pretty easy to add to the existing JDOM and dom4j adapters. I'm hoping to spend some time on this project before the end of the month (extending it to full infoset compatibility and adding adapters). - Dennis Mark Gertsvolf wrote: >Jeff/John, > >Thank you for your answers. > >In fact when I increase the stack size the Stack overflow exception disappears and the: >RMI error: java.RMI.UmnarshalException is thrown instead from deep inside the >ObjectInputSteam.readObject. >The exception is caused by java.io.EOFException > >This problem only occurs if the original XML is large enough. > >Any ideas? > >Thanks again. >Mark. > > > >Jeff Orris wrote: > > > >>You can increase the stack size with the -Xss option on the java command, >>i.e., java -Xss64m. >> >> >> Mark Gertsvolf >> <[EMAIL PROTECTED] To: [EMAIL PROTECTED] >> com> cc: >> Subject: Passing large XML Document object via RMI >> 06/16/02 09:42 >> AM >> Please respond >> to xerces-j-user >> >> >> >>Hello everybody, >> >>While using Xerces-J version 2.0.1. >>I am having a problem with passing a large XML Document via RMI.
