Re: [gridsam-discuss] Using APIs to submit job to GridSam Web service

[William L. <ww...@do...>]

Sorry, my fault.

It's the directory containing those files must be in the CLASSPATH  
(i.e. /home/ligang/OMIICLIENT/conf/). If that doesn't work, you might  
need to specify a java system property (using -D in the command-line  
or programmatically) "axis.ClientConfigFile" to point to the client- 
config.wsdd file location (e.g. -Daxis.ClientConfigFile=/home/ligang/ 
OMIICLIENT/conf/client-config.wsdd). This is a quirk in the way Axis  
loads its client-side configuration.

By the way, I'm cc'ing this e-mail to Vesso Novov, who will take over  
the GridSAM development from me. I've also forwarded this e-mail to  
the GridSAM mailing-list as a record for others in a similar situation.

Regards,

William
