Hello:
I have build derby successfully on RI. But when I tried to run
the following derby's test on Harmony, it failed.
*java -Dframework=DerbyNetClient
org.apache.derbyTesting.functionTests.harness.RunTest lang/supersimple.sql *
Btw, this test passed on RI.
(1) If the VM is J9vm, at first the test can't even be launched. After
applying the Sian's patch, this error seems to be fixed.
But the test still failed because of a strange reason, the error report
is described as following:
*java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver
at java.lang.Class.forName(Class.java:129)

I find that the class *org.apache.derby.jdbc.EmbeddedDriver * exists,
and I have included this class in ClassPath.
I write a simple test to load this class, it works.
(2) If the VM is DRLVM, the test can't be launched, I paste the error
report in command line here:

Has anybody ever met the same problem?

Hi, all:
I now plan to make the self-host of Derby on Harmony.
Is there anyone interested in this topic?
Here is what I encountered in the process. Hope it will be helpful to
anybody who is interested in it.
At first, the testcases even fails on RI both on windows and
ubuntu and
the result are different.???
After some struggiling, I have successfully passed the provided
testcases on RI after I rebuild the source on my machine.
But there still remains a problem:
The derby team kindly rewrite the launcher for testcases in order to
treat J9 vm differently if the property java.vm.name starts with "j9".
But
the j9 vm used in Harmony has been customized thus is different from
traditional j9 vm that is expected by derby. This leads to failure to
launch
tests.
I will talk on Derby's mailing list to find a solution.
