Sr. Programmer Analyst

Responsibilities:

• Used wsconsume for Document style type and used Axis for RPC style type wsdls
• When new clients are generated I integrated them in the code and eliminate all the dependencies upon weblogic
• For this integration I need to make sure the core functionality is not modified and only the new client dependencies should be resolved
• Once it’s migrated my responsibility is to deploy it in the jboss6 and validate calling it from both weblogic clients as well as JBoss clients
• The invocation should be working properly
• As a Tech Lead, Developed and maintained a check list based upon lesson learned from each migration
• This is bringing ease in each new migration by following the footprints of prior experiences to me and other team members
• Code review to make sure and validate above check list is followed by teammates
• Migration of web services clients from weblogic9.2 to JBoss 6.4 EAP
• Utilization of JBoss provided tools “wsconsume” to migrate Document Style
• Utilization of Axis to migrate PRC style web service’s clients
• New technologies forced to change the web service port initialization code
• Made sure that only web service port initialization code is changed not the business logic and API invocation
• Integration of migrated web service clients into migrated source code
• Making sure of un-changed contract (WSDL), so that existing clients of migrated web service don’t suffer outage
