Re: Where's my Derby?

Derby aka JavaDB is included in JDK 1.6, right? So what's happening here:
$ java -version
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)
$ javap org.apache.derby.jdbc.EmbeddedDriver
ERROR:Could not find org.apache.derby.jdbc.EmbeddedDriver
What's happening there is that you didn't include Derby in the classpath.
I have Derby, which came with the 1.6.0_18 download but had also come with my
earlier 1.6 downloads, and get the same exact result from that command that
you do. OTOH, when I command
$ javap -classpath /opt/java/java/db/lib/derby.jar \
org.apache.derby.jdbc.EmbeddedDriver
I get back:
public class org.apache.derby.jdbc.EmbeddedDriver extends java.lang.Object
implements java.sql.Driver{
public org.apache.derby.jdbc.EmbeddedDriver();
public boolean acceptsURL(java.lang.String) throws
java.sql.SQLException;
public java.sql.Connection connect(java.lang.String,
java.util.Properties) throws java.sql.SQLException;
public java.sql.DriverPropertyInfo[] getPropertyInfo(java.lang.String,
java.util.Properties) throws java.sql.SQLException;
public int getMajorVersion();
public int getMinorVersion();
public boolean jdbcCompliant();
static void boot();
static {};
}
Ergo I conclude you have Derby, too, and that it came with your JDK download.
Am i [sic] looking for the wrong driver class? Or do i [sic] have to include some
special jar on the classpath? I searched the entire JDK installation for
Apparently not the *entire* installation.
a mention of EmbeddedDriver, and there was none. Do i [sic] have some special
version of 1.6 which lacks Derby? I have whatever came with Eeebuntu 3,
which is basically Ubuntu 9.04.
I haven't used Derby since before 1.6, so i have no positive control for
how this should work.
Anyway, since it looked like Derby would be a separate download for me,
i [sic] went with H2 instead :).
It's too bad your reason wasn't valid, at least not based on the information
you provided here.
