Application partitioning and scalability questions

Question

I split my application into dozen or so jars...
1) Original project had ADF BC BaseClasses overridden... Any way to "share" them now among projects?
2) How to handle common java files to all projects such as JsfUtil, AdfUtil?
3) Common resource files, png's
4) Jdev 11.1.2: How can I exclude folder from jar deployment (test jsfs)? Don't see any filter options on deployment profile ?
5) What do you guys do with common EO, VO, lookups as far as sharing or will each project have to have own copy?
6) How can I minimize number of database connections?
Thanks,
Brian

+1) Original project had ADF BC BaseClasses overridden... Any way to "share" them now among projects?+
Put them into a JAR file and configure them in the JDev preferences for ADF BC.
+2) How to handle common java files to all projects such as JsfUtil, AdfUtil?+
WLS shared libraries if you want to maintain a single deployment. Otherwise use a JAR and add them to each project
+3) Common resource files, png's+
See sample 86 on http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html#CodeCornerSamples
+4) Jdev 11.1.2: How can I exclude folder from jar deployment (test jsfs)? Don't see any filter options on deployment profile ?+
Check the project source settings and remove the folder
+5) What do you guys do with common EO, VO, lookups as far as sharing or will each project have to have own copy?+
Depends on the use case. If it is common for an application you can use Shared AM to avoid each session to create its own instance. If its about sharing the code therein, use ADF libraries for cross application use
+6) How can I minimize number of database connections?+
Use AM pooling, avoid too many root AM, use DataControl sharing on bounded task flows
