Problem running GigaSpaces-Excel Market-Data Example

Hi there,

I'm testing out the GigaSpaces-Excel Market-Data Example for couple of hours by following the exact instructions provided in the Link: [ http://www.gigaspaces.com/wiki/displa... ]. Everything compiles fine and I saw 15 objects are written to the space. However when I open the provided Excel spreadsheet, Gigaspaces outputs the following errors:

Sep 10, 2008 3:55:43 PM SEVERE [com.gigaspaces.core.engine]: Incompatible Class Change Error - an incomp atible class change has occurred.

Clearly, the checksum from the two are different and the data type is also different for each property. Any advice on this issue?

Regards,

Jerry

The only difference if it makes a difference is that I'm using Gigaspaces 6.5. The example seems to require 6.0?!

Hi Jerry,

The reason you get the exception is because the example is compatible with XAP 6.0 version only. I’ll updated a new version to the site and let you know.
Sorry for the misunderstanding.

Hi Guy,

Thanks, please let me know once you have developed the example compatible with GigaXAP 6.5

Thanks.
