Redeploying in SUN ONE 6.0

[Miguel Gonzalez]

Hello,
I need to re-deploy applications in my Sun ONE 6.0 web server. I do it from the command line with the following script:
IWS_SERVER_HOME=/wac/iplanet2
export IWS_SERVER_HOME
wdeploy deploy -u /su -i su_desarrollo -v https-su_desarrollo -d /wac/wserver/su/su_desarrollo
/ws su.war
I get the following answer:
[wdeploy] The war file name su.war
[wdeploy] Deploying web application
[wdeploy] Loading new configuration
[wdeploy] This web application is already deployed
But if I do it from de Administration Web site there is not such a problem with the existing server. Should I do first an undeploy or delete?
Regards,
Miguel.
