[scripting] RE: Adding Logging to Script

[Joe Pochedley]

Is this the complete script as you're trying to run it?  It's setup as a 
function (CmdletBinding(), OutputType() ,Parameters, etc)...  But you're 
missing the Function definition and enclosure....  From the Comment block at 
the top, the function looks like it should be called Uninstall-Java

So, it should look like (after the end of the comment block):

function Uninstall-Java
{

    [CmdletBinding()]
    [OutputType([int])]
    Param
....
<rest of script here>
....
}

Need to be sure to replace the curly brace at the end too...  Then the function 
needs to be called, otherwise all you've done is load the function...

Alternately, if you just want a simple script you can remove the Function 
components but then you'll have to restructure a bit (some might call this bad 
form too).  :)

Does it work if you run it manually?   Reason I ask is because the wmi query 
has weird quotes around the query string.  Maybe that's just a side effect of 
pasting into the email though.  (was the code originally copied from a web page 
somewhere?)

Can someone show me how to make this script write a log? I deployed it from 
ConfigMgr and it never completed so I need to be able to troubleshoot it 
somehow.

.Synopsis
   Finds all Oracle Java products (excluding the auto updater which actually 
gets uninstalled when the main install is removed).
.DESCRIPTION
   Identifies and uninstalls Oracle's Java software from the local machine 
using WMI. The query to locate the installed software interogates the 
WIN32_Products class and includes exclusions to avoid matches to third party 
software that has "Java" in it's name.
   Use the -KeepVersion argument to specifiy a version to keep installed on a 
computer.
   Use the -Whatif switch to test the result without actually uninstalling 
anything.

   The script will return the results of the WMI query as an object array.
   Credit to commenter on my blog "Carsten" who supplied an expanded list of 
software to exclude.
   Note: this script is supplied "as is" and has not been fully tested for all 
possible scenarios. Use at your own risk and do full testing before using in 
production.

.EXAMPLE
   Uninstall-Java
   Uninstalls all versions of Java
.EXAMPLE
   Uninstall-Java -KeepVersion "7.0.45"
   Uninstalls all Java except version that starts with "7.0.45"
