mapping string values with corresponding formats

I have to process many strings( thousands ) which are in either of the two formats as below:

============= Examples of Str=============
123|S|122.14,
S,344,122.146

==============================================
The format of these strings are

A|B|C

B,A,C

I want them as A=123 B=S C=122.14

and A=344, B=S, C=122.146 ( where A , B , C correspond to column names and can be loaded into sql server db )

How do I do this.

I can use split to get the substrings as values. How do I map these values with formats and load them?

Please help. Thanks

Upgrade spring-flex from 1.0.3 to 1.5.2 causes NullPointerException

I have been trying to upgrade spring-flex 1.0.3 to 1.5.2 in order to check new features, i.e. Hibernate lazy fetching support in BlazeDS 4. I downloaded all necessary packages, changed dependencies in Maven for Spring (to 3.0.7), Hibernate (to 3.6.9) and Spring flex core (to 1.5.2). When I try to build and deploy application, I got NullPointerException which indicates cause in my domain class (at the end of stack trace):

Getting custom HTTP request headers in web.py?

I know that, with web.ctx.env, I can get a lot of information that comes from the headers -- but only the standard headers. Is it possible to obtain all HTTP request headers from within a GET or POST method in web.py?
