The idea was that I wanted to write an Android application which created a JDBC connection to a Derby database served by the Derby network server on some other machine, and then I would use JDBC calls to access data from that Derby server over the network.
- Added derbyclient.jar to the libs directory of my sample application
- Imported java.sql.DriverManager and java.sql.Connection into my HelloAndroid.java class
- Tried to call DriverManager.getConnection
My application crashed.
The application HelloAndroid (process com.example.helloandroid) has stopped unexpectedly. Please try again.
So I searched around for a while, and found adb logcat, and ran that and re-directed the output to a file so I could look through it.
In the logcat output, I found this:
I/dalvikvm( 348): Failed resolving Lorg/apache/derby/jdbc/ClientBaseDataSource;
interface 212 'Ljavax/naming/Referenceable;'
I see in the Android docs that, indeed, javax.naming is not listed as a supported package.
And, unfortunately, references to javax.naming exist in a number of places in the Derby source, so this is kind of a significant problem.
I'm not quite sure what to do next, but for now I posted this finding to DERBY-4458 since that seemed like a reasonable place to track the info.
We'll see if anybody posts any suggestions there.
