Developing Application for third-party Java API (jar) libraries

[Former Member]

I need some of your inputs on architecting a web based solution to invoke Vantive java API using SAP Netweaver Technology. The API provides methods to connect, insert, update, fetch data from Vantive system using java classes. Pl. let me know which would be best way (webdynpro/ j2ee/java) to create & run web based forms to connect, insert and update data in Vantive using these Java APIs.

I think there is your choice only that based on your experience with web technologies (in case of integration with portal as I understood) but the nominee with the best integration capabilities is Dynpro. Of course you can simply use standard JEE techniques (see the official JSR for official technology and release notes of official restrictions by SAP implementation). Third party integrations are available in both choices: Dynpro or not. In general your choice is better to be with an appropriate estimation, isn't it? Or try to define concretely criteria of such integration.

Should we use XI to create web service and use as model or call these API methods from controller directly?

Nevermind. There is no general solution but your usage regards to your scenarios: complexity of implementation, integration with the other possible external systems. If you have no integration, not many steps (=services to call) it's easier to go without XI. Otherwise you could think twice about architecture of your aplication in case of future planned supporting.

Hi,

just to create webservice you dont need to integrate with XI.

You can create webservices from java and j2ee projects in NW .
