Keyword: can we get the project db4ome( platform of eclipse+eclipseme) before it is released? email to: talent_marquis@163.com or database.ustc@163.com  I'm a student from USTC, China. Now we have a research on The Implement of Mobile Database based on DB4O. We tried to use DB4O+J2ME to ...

Patrick Roemer: It might work, but we would lose IDE support for the CLDC module, which will make it much harder to ensure and maintain CLDC compatibility - the ''refactor dependencies'' (and maintain them) is the hard part here. Accumulating the CLDC sources based on package naming conventions also sounds much more fragile to me than ...

Here is another option as food-for-thought: - Keep all the basic sources in db4oj as is, without introducing yet another db4omicro project. - Refactor the package dependancies in db4oj so we get a set of packages that is compalibale on J2ME CLDC and does not depend on anything else. - Create a script that produces an EclipseME project from this ...

Hola que tal a todos, tengo unas dudas ya que soy nuevo en db4o y pues básicamente es lo siguiente: estoy desarrollando una aplicación móvil J2ME CLDC1.1 y MIDP2.0 y necesito guardar unos datos en una ''base de datos móvil'' y si estoy en lo correcto db4o lo puede hacer el problema es cómo??? no tengo idea... no se si se agrega como una librería ...

I finally made some time to grab the db4oME spike out of SVN and tried to build and run it against the Sun WTK 2.3 (CLDC 1.1/MIDP 2.0) using EclipseME 1.6.5.  There are two problems I encountered.  First, com.db4o.YapFile causes an unspecified error during preverification.  Second, when I launch com.db4o.test.Db4oTestMidlet I get a ...

treeder:What platform requirements would there be for using db4o on a mobile phone, CLDC:- JSR-75 (FileConnection API)? JSR-75 probably won't help us much. IIRC, FileConnection only provides file access via InputStreams, db4o needs random access. The spike (db4oME in SVN) is based on an IoAdapter that applies a uniform sized tiling to the yap ...

The spike in subversion solves the issue with reflection: We provide a tool that adds ''reflection'' functionality to application classes and we use a special reflector that works with it. File access is solved in a similar way: db4o file IO is pluggable and the implementation we tested with uses recordstore.   I know SuperWaba a little ...

Hello davidbeers, we have a spike in our SVN that tests running on CLDC. The project name is db4oME. If you would like to see CLDC take a high priority, please vote for this issue: http://tracker.db4o.com/jira/browse/COR-170
