Find 'net_rim_api.jar' version?

Question

Usually, Blackberry library comes with JDE named "net_rim_api.jar".

Now, the problem with how we come to know the API version ?

Let me explain to avoid digress viewers at all,

• suppose you just get "net_rim_api.jar" by somewhere/somehow

• Totally unaware about its relevant JDE

  Now, how you come to know the API version like 4.7 or .... ?

Cheers, Amit.

Answer 1

Ok, 'net_rim_api.jar' as any jar is an archive, so you extract the archive to a temp folder, open any .cod file from the root folder and look through with a HEX viewer. For instance, on my PC I have 2 JDEs (4.7 and 6.0), so I extract both jars, open 'net_rim_pdap_resources.cod' (just because it is the smallest .cod file) and (hurray!) I am able to observe the desired difference by these substrings:

• 6.0.0.141.net_rim_cldc.net_rim_pdap_resources
• 4.7.0.75.net_rim_cldc.net_rim_pdap_resources

Answer 2

Go to the project properties and then look at the Java Build Path. It should say in Libraries tab which version you are using.
