#build properties
mywebappear=D:/data/code/WebSphereAntFiles/scripts/test/mywebappEAR.ear



#WAS6 install directory
was_home=C:/IBM/WID7_WTE/runtimes/bi_v7
#server name (see cell/node/server; e.g. "server1")
was_server=server1
#user + password; for use when security is enabled
was_user=admin
was_password=admin
#stops scripts on problem
was_failonerror=true
#virtual host
was_virtualhost=default_host

#Absolute path to EAR file
#was_ear=fooEAR.ear

#Name of the enterprise application
