The following is my requirement :
The first web page for user authentcation to the application.The user will enter his ID and Password and his dipartment and this request will be validated against tha data in a database. If the user is a valid one then it will go to the next(2nd step) page and if not valid then it will show the proper error messge.
In the next page the user will post a .xsl file. The webmethods service will receive that and parse it and create a xml doc and call a webservice and pass this data.At the mean time the user will see the status as processing.If any error occurs it will show appropriate error massage with detail.If processing is succefully completed then it will show the user the success and the time of cmpletion.
Can any body suggest me how can I incorporate this using DSP and where I will use HTML and where DSP and how to control the flow.
