/*
 *<rickcr-r> and then maybe when they login you set the datasource name
<rickcr-r> hmm
<Spinlock> ya, that might work
<Jerome> boo
<rickcr-r> yea that's what id do
<rickcr-r> hi jerome
<Jerome> select tableName.* from databaseName.tableName where tableName.bla = 4
<Jerome> problem sovled.
<Jerome> Here's the ibatis version
<Jerome> select tableName.* from $clientName$.tableName where tableName.bla = 4
<Jerome> iBatis version
<Spinlock> hmm, I like it
<Spinlock> just trying to think how it would work
<Jerome> or rather
<Jerome> select tableName.* from $clientName$.tableName where tableName.bla = #valueObject.bla#
<Jerome> queryForList("select bla", Map<String,String>())
<Jerome> where the map =
<Jerome> map (clientName => 'Rickisgayinc', valueObject => new BallsInMyMouth(40))
<Spinlock> haha
<Spinlock> but at the log in page I need to have the company name in the url as the company log show up on the login page
<Spinlock> but that's minor potato's
<Jerome> ez
<Spinlock> next q, is sata-2 raid hot swappable?
<Jerome> Which raid mode
<Spinlock> 5
<Jerome> Go raid 5
<Jerome> Yesh
<Jerome> (IF you have the hotswappable drive bays)
<Spinlock> ah yes, I've seen those
<Spinlock> so if there's 3 drives in total, if one fails, just a simple swap and the array builds itself while tomcat is still dish'n up content?
<Jerome> Yes
<Jerome> You could lose one drive
<Spinlock> oh good  :)
