[oscar-devel] CLDC-No Reflect, Memory estimations querry

[paramjeet c. <par...@pa...>]

Hi,

I spent some time to evaluate OSCAR/OSGi on J2ME CLDC. I thought its better
to have an experts opinion. As CLDC does not support Reflect Classes and
Serializable, so what impact does it have on OSGi framework. Do Reflects and
Serializable have crucial role in implementation of the framework?

Another question is, What is amount of RAM & Flash, CPU Hz required to run
minimum version of OSGi ?
it would be helpful to me if you provide me various break ups of CDC, FP,
Framework size etc.

Thanking you in anticipation.

Regards

Paramjeet

Hi,=20
OSGi v3 has a specific section about the java API requirements. It's
called "Execution Environment Specification". That speficication lists
all classes that java VM needs to provide in order to build an OSGi imple=
mentation.
There are two flavors : foundation (which is extracted mainly from CDC
profile) and minimal which is a subset (I think) centered for OSGi
requirements.=20

Both Reflection and Serialisation apis are needed in both flavors.=20

You can find the API lists for both flavors on OSGi web site, as jar
files.=20

The second question is now :=20
  - What is .... to run a java VM compliant to the minimal
    requirements... No idea for the moment.=20
