Blackberry Widget vs Java SDK

I am new to this forum, I have been viewing documents from both the Blackberry Widget and the Java SDK. I have the following doubts to find out: -

1) Advantages and disadvantages of Java SDK and Widget SDK?

2) When do I need to upgrade to the Java SDK and Widget SDK?

3) Do Java and Widget applications require the latest version of Blackberry OS 5.0? OR are they compatible with lower versions?

4) Whatever you develop with the Java SDK, can this be done using the SDK widget? similarly the opposite?

5) Is it possible to create .java classes for developing Widget applications?

6) Do all Blackberry models support both Java and Widget?

7) What databases support Java and Widget Blackberry?

Please shed some light on this, since I could not find the appropriate documentation.

Thanks Rithu

Lack of SDK widget

  • Between pages slower
  • There are performance issues.

Using the Java SDK is much faster than the Widget SDK
