The
business case
Our client (a substantial and well-known City institution) had several
applications written in a variety of 3rd generation languages and on a
variety of platforms that were becoming difficult and costly to maintain.
They decided to standardise both development software and hardware; they
committed to rewriting existing core applications and mandated future
developments be in their chosen environment.
The
technical case
The client selected BEA WebLogic Server under Solaris before NT/e became
involved. The client recognised that in order to effect the changeover
effectively some outside advice was essential to mentor their existing
staff in J2EE best practice, assist in development and be a conduit for
problem-solving.
Our
input
The NT/e consultancy was able to combine:
• Experience of WebLogic/Solaris installations, JBuilder and
Rational Rose, with
• Experience of the client's historic VMS/NT/UNIX environments
in place, and
• Access to specialist expertise within BEA and NT/e as necessary.
| This
has resulted in the client's expectations being met. Additionally: |

Results/benefits

transfer to the client's staff, reducing training time and costs.

and deployment systems.
