I think the abruptness of lancelotlinc's response was a subtle indication that 'he was giving you as much information as you are giving him'. You really need to give us more information to be able to help you.
What is this BLOB that you want to create a thumbnail out of? Is it a JPEG image? You are most likely going to want to look into Java libraries for modifying images if so - and call it from a JavaComputeNode. |

WMB, when used as an ESB, has three main value propositions:
1. Transformation of data from one format to the other.
2. Content-based routing of data.
3. Service aggregation.
So WMB is designed to handle your requirement to transform data from your BLOB format to your THUMBNAIL format.
This forum is a technical help for people who are stuck on a problem. The moderators of the forum have specifically stated that training on the product is to be accomplished from other means. Like IBM class WM663 and WM664.
Have you attended these classes? If not, why not.
Getting back to your question, what have you tried, and why do you believe what you tried does not work?

What's a thumbnail?
I mean, I have one on each of my thumbs, but how does that relate to anything inside broker - except that I use my thumbs to type keys and push buttons to use Broker.
What's a BLOB? What does it actually *consist* of? What's the difference between a thumbnail and a BLOB, at a *deep* level?
What does Oracle want you to give it, if it is what is asking for 'a thumbnail'?
Why are you asking this question of us, rather than making efforts to answer it yourself, and demonstrating those efforts? |
