java.lang.NoClassDefFoundError when calling the Java function from Powershell Script

Question

I'm trying to convert a .bat file that actually run a java statement into a PowerShell script, mainly because the .bat file have the user/password hardcoded and a

set /p password="Enter password: " %=%

did not hide the password from the command prompt.

The java command that works fine when I run that from a .bat file or directly from dos prompt and also when I run that from the .bat file.

I ensure that all environment variables are in place as they are set in the batch file.

My problem reside on the following:

When I run it from the command line or directly from the command prompt the java works fine,

when I try run that using the cmd.exe /c to run the line directly doesn't work and if I call the .bat file from the powershell it doesn't work and give the following error.

cmd : java.lang.NoClassDefFoundError

I don't get it... why manually I can run and through the PowerShell script it doesn't work?

Here is my .BAT file that works fine:

@rem ###################################
set IIQPATH=C:\IIQ\IIQ
set exportpath=C:\EXPORT
set /p userid="Enter ID: " %=%
set /p password="Enter password: " %=%
@rem ##################################
echo %exportpath%
set CLASSPATH=%CLASSPATH%;%IIQPATH%\WEB-INF\classes
set CLASSPATH=%CLASSPATH%;%IIQPATH%\WEB-INF\lib\identityiq.jar
set CLASSPATH=%CLASSPATH%;%IIQPATH%\WEB-INF\lib\sqljdbc4.jar
set CLASSPATH=%CLASSPATH%;./split

@rem Export the objects

java sailpoint.launch.Launcher console iiqBeans -u %userid% -p %password% -c "export -clean %exportpath%\Application.xml Application"

Here is my PowerShell code

$iiquser = Read-Host 'Provide User for'$target2' environment'
$iiqpass = Read-Host 'Provide Password?' -AsSecureString
$actualdate=Get-Date -format MM_dd_yyyy
$iiquser
$iiqpass

Push-Location C:\EXPORT

$env:IIQPATH="C:\IIQ\IIQ"
$env:exportpath="C:\EXPORT"
Remove-Item env:CLASSPATH
$env:CLASSPATH="$env:CLASSPATH;$env:IIQPATH\WEB-INF\classes"
$env:CLASSPATH="$env:CLASSPATH;$env:IIQPATH\WEB-INF\lib\identityiq.jar`$time"
$env:CLASSPATH="$env:CLASSPATH;$env:IIQPATH\WEB-INF\lib\sqljdbc4.jar"
$env:CLASSPATH="$env:CLASSPATH;./split"

$commandline="java sailpoint.launch.Launcher console iiqBeans -u $iiquser -p $iiqpass -c "+[char]34+"export -clean $env:exportpath\Application.xml Application"+[char]34

$commandline

cmd /c $commandline

Any hints?

======================= Quick update...

I manually set the variables in cmd windows prompt and into PS Cmd prompt.

when I run my java command without parameters I got the following

C:\>java sailpoint.launch.Launcher
Usage: sailpoint.launch.Launcher [ -d ] [<application> | <class>] <arguments>...

Applications:
  setup           Bootstrap configuration utility
  schema          Schema file generator
  upgrade         Perform data upgrades between releases
  patch           Perform data upgrades post release
  console         Administrative console
  encrypt         Administrative console
  integration     Integration console
  oim             OIM Integration console
  exportschema    Data Export console
  exportviews     View Export console
  keystore        Key Store console
  parse           XML file parser

But when I try run that in PS Command line I got the following:

PS C:\> java sailpoint.launch.Launcher
Exception in thread "main" java.lang.NoClassDefFoundError: sailpoint/launch/Launcher
Caused by: java.lang.ClassNotFoundException: sailpoint.launch.Launcher

Could not find the main class: sailpoint.launch.Launcher.  Program will exit.

Did you try displaying the CLASSPATH just before invoking the command to make sure it's set the way you expect? — Jim Garrison
Hey Jim.. Yes.. I did... CLASHPATH in the PS session have exactly the same value of CLASSPATH in the DOS PROMPT. — CrazySpy

The command that should be used is

java -cp .\identityiq.jar sailpoint.launch.Launcher

The -cp option is responsible to setup the CLASSPATH in the Powershell command line.
