Unable to create Java Virtual Machine

[sparq]

Hi,
This is my first post, so be gentle with me (lol).
Here is our environment:-

OS: Windows Server 2008 R2 Sp1 (64bit) and InfoServer8.5 with Fp1 (64bit).
Instillation Path D:\IBM\InformationServer
JRE and JDK (64bit) installed on Windows (D:\Java\jre6_x64 and D:\Java\jdk6_x64).

We are looking at the jxl.jar example to read an excell spreadsheet.

The job is simple.
Java Client->DataSet
Users Classpath points to E:\Source\TEMP\jxl.jar
We are getting an error message:-
Java_Client_3,0: Fatal Error: Fatal: TJClient::initialize: unable to create Java Virtual Machine; classpath = D:\IBM\InformationServer\Server\DSEngine\java/lib/tr4j.jar
ASCL-DSJNI-00011`:`JNIWrapper: load library failed: directory D:\IBM\InformationServer\Server\DSEngine\../../ASBNode/apps/jre\D:\Java\jre6_x64\bin, name jvm
The specified module could not be found.

IDATASTAGE_JRE=D:\IBM\InformationServer\ASBNode\apps\jre
DATASTAGE_JVM=D:\Java\jre6_x64\bin
DSHOME=D:\IBM\InformationServer\Server\DSEngine

Can anyone help with this
?
