serialization problem with large xml documents
Dear axis2c users:
Maybe this problem has to do with the library libxml2, particularly with the structure xmlBuffer.
I have the following code:
axiom_node_serialize(om_node, env, om_output);
buffer = (axis2_char_t *) axiom_xml_writer_get_xml(xml_writer, env);
printf( "size of buffer=%d, actual size=%d\n",
axiom_xml_writer_get_xml_size(xml_writer, env), strlen(buffer) );
the output is:
size of buffer=27558, actual size=16396.
Does not include the serialized xml document, but to see the sizes is that it is incomplete.
this problem has to do with large xml documents (> 27300 bytes).
thank you all.

Hi:
I'm using a g++ compiler in a Pentium 4 Computer over Linux 2.6.32-41, I guess the pointer size are determined by the architecture. I don't use far nor near pointers in my code.
Atanacio.

Dear Atanacio
Check your Code and make sure all pointer are at least 32 bit pointers.
Often you have just problems when one of the many pointers is of a 16 bit size.
Pointer Size matters and are important when larger buffers come to play.

Hi Atanacio + all,
when reading this I vaguely remembered that I had a problem similar to
yours ... I looked through my mail and found this:

=====
Look for that thread for the complete info. Essentially:
- I found that XML structures are messed up between server and client
- happens with large docs (in my case ~500k)
- happens with Axis2C 1.6
- happens with Guththila XML library (default) but NOT with libxml2
So, if you did not rebuild the sources yourself, you are probably using
libguththila, in my case replacing it with libxml2 (what I wanted to do
anyway) helped.
Rgds,
tge

Dear Atanacio
Check your Code and make sure all pointer are at least 32 bit pointers.
Often you have just problems when one of the many pointers is of a 16
bit size.
