Subject [jira] Updated: (DERBY-3176) J2ME support for phoneME platform disabled in 10.3
Date Tue, 13 Nov 2007 13:52:51 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3176?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

John H. Embretsen updated DERBY-3176:

    Attachment: MobileSanityTest.java

I wasn't able to try the latest patch before the commit, but when testing my phoneME binaries
with the current trunk I get this error message when invoking IJ:

ERROR (no SQLState): org.apache.derby.jdbc.EmbeddedDriver is not registered with the JDBC
driver manager

I get the same error whether I run with pre-built phoneME Advanced binaries and a self-built
JSR-169 implementation, or self-built phoneME binaries including the self-built JSR-169 support.

I've also tried another approach by using a java class instead of IJ (attached: MobileSanityTest.java),
but I get the same error. The exception originates in the EmbeddedSimpleDataSource.findDriver()
method. With 10.2 it works fine, and with I get the DataValueFactory error, as expected.

sysinfo seems to be correct, e.g.:

java.specification.name: Foundation Profile Specification
java.specification.version: 1.1
--------- Derby Information --------
JRE - JDBC: J2ME - JDBC for CDC/FP 1.1

Rick, are you able to use IJ/Derby successfully using phoneME and the current trunk?
If so, what could I be doing wrong?

> Derby 10.2 runs on the phoneME small device platform. However, on that platform Derby
10.3 fails to boot databases, complaining that Derby cannot find an appropriate implementation
of DataValueFactory.
> For details on how to install and run the phoneME platform, please see http://blogs.sun.com/wittyman/entry/javadb_on_sun_javame_cdc
These are great instructions but I needed to adjust them as follows:
> 1) I had to use 10.2 because 10.3 and the development mainline would not run on this
> 2) I needed to to set LD_LIBRARY_PATH so that the vm could find the necessary shared
> Here is the phoneME startup script which worked for me:
