I had a quick look at the patch (in source code format, so I did not apply the patch and check the rendered results in a web browser).
Generally it looks good, though I'd like to see some minor changes:
+C:\Apache\db-derby-10.4.1.3-bin\bin> java -jar derbyrun.jar server start
I do not think that command will work if your current working directory is the bin directory, as shown. When using the java -jar invocation method you need to reference the jar file directly. Something like this would work:
+C:\Apache\db-derby-10.4.1.3-bin> java -jar lib\derbyrun.jar server start
+C:\Apache\db-derby-10.4.1.3-bin\lib> java -jar derbyrun.jar server start
Less importantly, as you are removing the entry for derby.jar in this context, maybe it would be good to let users know that they still need to have the jar file in the same location as before. This is just a suggestion, e.g. like this:
<span class="codefrag">derbynet.jar</span>: contains the code for
- the Derby Network Server
+ the Derby Network Server and a reference to the engine jar file (derby.jar)
Finally, I suggest changing the header "An easier way" to "An easier way: derbyrun.jar" or something like that, which I think would be more informative. Perhaps others have a better suggestion?
