Hello,
I have generated a client from wsdl in Eclipse 3.3.
The webservice I am calling, can issue large amounts of data (several mb
of data) according to the selections specified on calling it.
If I choose a selection delivering only a small aount of data everything
working fine, if not then I get the following exception:
**************************************************************************************************

*********************************************************************************
I have played around with various versions of xerxes XML parser:
Xerxes 2.9.1 is working better than 1.4.4, but also collapses once a
certain amount of data has been selected.
I have also played around with "org.globus.axis.transport.HTTPUtils" as
advised on this mailing list:
//force http 1.1
HTTPUtils.setHTTPVersion((Z_MB_GET_ALL_NOTIFS_WS_EXTBindingStub)myConfigGetAllNotifs,
false);
//set chunkedEncoding
HTTPUtils.setDisableChunking((Z_MB_GET_ALL_NOTIFS_WS_EXTBindingStub)myConfigGetAllNotifs,
false);
But whatever combination I tried, I got no positive result.
Unfortunately the test setup for the webservice does not allow access
via http, but only via https, which means that I cannot ( or can I? )
insert a TCP sniffer like tcpmon.
For that reason I am unable to access the returning SOAP message.
I am able to access the webservice server (SAP ERP system) and cannot
find any error messages there.
To be honest, I am not a ws geek and lost here...
Any hints?
Thanks
Matthias
