My Objectives for Today:
• Describe all of the content APIs available in P8
4.x (applies to all P8 CE 4.x releases)
• Describe compatibility with P8 3.x content APIs
• Describe how to decide among the APIs
• Describe what to do about existing and new
content applications
Good News!
• For existing apps
– Compatibility situation is really good
– You (probably) don’t even need to recompile
• For new apps
– We have an API that fits you
– Development stack agnostic
• Java / .Net / Web Services

Summary of
4.x API Changes
• New APIs
– CE Java API
– CE .Net API
• Backward compatibility
–
–
–
–
CE 3.x Java API
COM API
CE Web Services 3.x
Reversed stack position of COM API
• Read compatibility notes: “Upgrade Custom
Applications” in install/upgrade guide
10
Data Provider Changes
• New 4.x JDBC data provider
– Content Engine OLEDB/ADO Data Provider is no longer
supported in 4.x
– Affects COM API
• CE Java and .Net APIs also provide native query APIs
– Richer
– “Closer to the metal” of the CE

Choosing an API
• What type of environment do you use?
– Java vs .NET vs web services
– The dominant factor … what’s natural for you?
• Best usability / functionality?
– Java vs .NET
– Web services powerful, suffers in usability
• Existing P8 3.x applications?
– Best long term strategy is to port to new APIs (see above)
– Compatibility layers (COM, Java) in the meantime
– You can mix old, new APIs (with some work and object
conversions)
Choosing an API (continued)
• Where’s the best performance?
–
–
–
–
–
Java with EJB transport
Java with WS transport, .Net, web services
Java 3.x Compatibility Layer
COM API
Relative performance is highly dependent on application mix.
The order here is just a rule of thumb.
• Server side code
– Event actions, autoclassification, lifecycle, etc
– Must use Java
