How to create a VBC without Script - XML Gateway

Key Points:


• Using XML Gateway Business Service to serve the VBC

• Using Business Integration Manager (Server Request) as Transport Protocol

• Create your own workflow to deal with the logic


Architecture:


• VBC trigger XML Gateway: Init(), Query(), etc

XML Gateway generates xml files corresponding to the command. Eg. It generates xml file

Matching Init() command

• XML Gateway triggers Business Integration Manager to invoke SendReceive() method



• Business Integration Manager sends the xml files generated by XML Gateway to Workflow



• Workflow gets the xml file and passes it to external application like MQ Series, MSMQ, HTTP Web Application or processes it inside the Siebel



• Workflow gets the result xml file from external application or Siebel Application and passes it back to Business Integration Manager (BIM)



• BIM receives the result xml file and passes back to XML Gateway to populate the VBC







Points of configuration:



• Create a BC of Class CSSBCVExtern



• Configure the above BC with following user properties

Service Name: XML Gateway

Service Parameters: Transport=EAI Business Integration Manager (Server

Request);ProcessName=;



• Create a process property as type of binary/string. Set the default to . It will hold the xml file generated by XML Gateway



• Create a process property as type of binary and named . It will pass back to BIM and XML Gateway to populate the VBC



• Analyse the xml file generated by XML Gateway to determine what action to be taken. (Query, Insert…)



• Use XSLT to transform the result xml file to the format XML Gateway needs to populate the VBC
