Hi Thomas,
This is a separate issue but last I heard about Dalvik is that there is still no support for dynamic bytecode translation at runtime - Derby generates bytecode dynamically for every new SQL statement, so I doubt you might be able to get Derby running on Android until dynamic bytecode translation is available in the Dalvik VM at runtime Cheers, --Francois 2009/12/1 Thomas Görres (JIRA) <jira@...>

You would think so but according to the Dalvik lead engineer, it is not: http://www.mail-archive.com/android-developers@.../msg29593.html This warning (not an error) is also reported by 'dx' translating some other Java libraries, not just derby.jar. Unless I'm mistaken, derby.jar GA is built using Java 1.4 which is obviously not a modern compiler? my guess is that this warning would disappear if building with Java 1.5 or 1.6. In any case, this is apparently NOT a blocking issue - Thomas was also reporting a Java OutOfMemory error which can be solved in Dalvik by increasing the heap size in dx.bat... Of course, even if the translation succeeds, Derby will not run, causing all kinds of errors due to its dynamic generated bytecode not being translated by the Dalvik VM at runtime, which is obviously a separate issue by itself. > Dalvik / Andoid compatibility > ----------------------------- > > Key: DERBY-4458 > URL: https://issues.apache.org/jira/browse/DERBY-4458 > Project: Derby > Issue Type: Improvement > Affects Versions: 10.5.3.0 > Environment: dx 1.2 (from the Android SDK 2.0) running on Java 1.6 > Reporter: Thomas Görres > Priority: Blocker > > derby.jar cannot be used on mobile devices running the Android OS.

[jira] Commented: (DERBY-4458) Dalvik / Andoid compatibility

I'm the Dalvik engineer referred to above. In fact, I believe the bytecode spec changed between 1.4 and 1.5. dx's warning is basically saying that 1.4-based code that uses inner classes doesn't provide enough information for a 1.5 runtime to faithfully report about them via reflection. Rather than try to halfway reconstruct the reflection info in such cases, dx just gives up and ignores inner classes info entirely. If your code doesn't make reflection calls to look at inner class stuff, then none of this makes any difference. Also, if dx is running out of memory, you can tell it to have a larger maximum heap size by using a passthrough option for the underlying vm that runs dx, e.g. "dx -JXmx2048m ...". Also also, while the Dalvik vm doesn't read .class files directly, you can in fact synthesize .dex files and use them, in a similar manner. I have seen a proof of concept where someone generated .class files, ran them through dx (treated as a library), and then loaded the result. It works, but it is admittedly not pretty, especially since the dx code isn't particularly geared for use in a memory-constrained environment (see above). In the long run, you'd be better off generating .dex files more directly, but it might at least unblock you.

I made some progress, but am having trouble because Derby's ClientBaseDataSource class implements javax.naming.Referenceable from the JNDI API, and Android apparently does not support javax.naming.* The error I get is: I/dalvikvm( 348): Failed resolving Lorg/apache/derby/jdbc/ClientBaseDataSource; interface 212 'Ljavax/naming/Referenceable;' Sure enough, javax.naming is *not* in the list of supported packages at http://developer.android.com/reference/packages.html > Dalvik / Andoid compatibility > ----------------------------- > > Key: DERBY-4458 > URL: https://issues.apache.org/jira/browse/DERBY-4458 > Project: Derby > Issue Type: Improvement > Affects Versions: 10.5.3.0 > Environment: dx 1.2 (from the Android SDK 2.0) running on Java 1.6 > Reporter: Thomas Görres > Priority: Blocker > > derby.jar cannot be used on mobile devices running the Android OS.
