OSB - initiaing with OSB

Question

Hello all,
My company decided to migrate all our web services to the new OSB and guess how they chose to get this up and running... It means I will be around bothering you guys for while... =D
Well, I'm building a prove of concept using a simple receiving, validating and queuing case...
1- Receive a request
2- Validate the request against the WSDL
2.1- Return error if request is not valid
3- validate the fields
3.1- Return error if one or many field(s) is/are not valid
3.2- Do a transformation of the fields in a xml
4- Insert in a queue.
So, what I've done so far was
- I've created a WSDL with three fields, firstName, surname and dateOfBirth
- I've created a Proxy service
- created a pipeline pair and inside my pipeline
- created a stage to validate the request. [validateRequest stage]
And here is my first question.
How would be a "best practice" to do this validation??
So far, I'm using a message processing > validate action and doing something like this:
Validate ./chec:person in variable person against CheckPersonWSDL ( Element = "person" ).
and
Raise Error on validation failure
Also, inside my validateRequest stage, I've added an error stage raising a error like this:
Raise Error using error code CheckPerson-001
with error Message
Request is not valid. Resubmit it with valid values.
Then, following my plan...
-I've added another stage into my pipeline pair to validate the fields received from the request. [validateFields stage]
Inside validateFields stage, I put a classical if/else cascade, validating each field in an if condition and inside each if block I inserted:
- a Message processing > assign action to...
assign fn:concat($body/chec:person/firstName, " is not a valid name.") to variable firstNameValidation
- a Message processing > assign action to do this:
assign fn:true() to variable isFirstNameValid.
So, after my cascade of ifs, I can check the second assigned variable and build a string with the invalid fields.
And here is my second question.
How could I use the variable previously defined by the assign actions??
e.g isFirstNameValid to check if it's true or not.
Well, basically, this is it... initially... =D
Thank you guys...

Answer 1

Ok...
Now I have my Proxy Service almost there...
I'm receiveing my request, validating what I want and sending to an iteration.
My request contains a list of people with the usual fields, first name, last name, date of birth and gender.
I want iterate this list, validate the person against a schema and for the valid ones, insert in a JMS Queue, and for the invalid ones, insert in my response to be resubmited.
So far, I've done something like this...
Added a stage... Validate People stage.
inside my Validate People stage, I've inserted a For each action to iterate my list.
for each person in my list, I validate against my schema and store the boolean result in a variable...
after I check using an if else action whether my person is valid or not...
For a valid person, I want to get that block of xml and insert in a JMS queue
The invalid person, I need to transform that block of xml to another xml and insert into the response.
now the questions... lots... =D
JMS queue...
How should I created it???
In my Weblogic??
Define a JNDI name and access it using a Business Service???
currently, I defined a business service as a message service with request message type xml pointing to my element inside my schema and no response and using JMS as my protocol and pointing to a random endpoint URI.
I know I'll have to change my endpoint URI to my real JMS queue but I need it first... =D
After that, I'm using a publish action pointing to my business service and my business service has a insert action.
My insert action contains the person variable defined as my for each variable of my for each action.
this leads me to my next question...
How to get the block of xml and insert into this JMS queue??
After that, I will have my if statement done... I hope _+
thank you guys for your help.
