Summary

Key Findings

and Recommendations

Deploy STRUTS as part of a Web Module within the application context (WEB-INF/lib)No SAP specific

configurations needed

Deploy AXIS API within the application context

Deploy Hibernate API and required libraries as shared libraries or a separate application

Configure the DataSource

SQL support layer according to your application needs (e.g. native_sql)

Using open _sql

could collide with Hibernates

primary key generation

Deploy Spring libraries as shared libraries whenever possible. Alternatively put them in WEB-INF/lib

Deploy JORAM API within the application contextUse the SAP Deployment API to deploy on NetWeaver

check SDN for download of the deployment clients

= Recommendation

= Note

KEY FINDING:

SAP NetWeaver

Application Server is an open platform for Open Source

frameworks
