Apologies for my clumsiness and sloppiness. The answers are indeed there in
the documentation.

Oops, noticed this text in Software Installation instructions:

If you have not already installed a JDK, download and install it now. No
specific vendor implementation is required; the only requirement is that it
be certified for J2SE 9 or higher. Java's reference implementation is at
http://www.oracle.com/technetwork/java/javase/downloads/index.html. After
installing the JDK of your choice, proceed to the next section.

So is there an older version of Apache Derby for JavaSE 8 ?

Thank you all for the suggestions. However, I decided to downgrade to Java
8 (OpenJDK 8), as I realized that the tutorial I was following was actually
also using OpenJDK 8, and I didn't feel confident to venture out without
help. I am however facing another issue with Derby, after downgrading where
it throws an error. Will make a separate post about it in a moment.

Re: Derby newbie - error seen creating 'seconddb' thru ij for network-server Derby

2019-11-08 Thread Bryan Pendleton
If you're just learning Derby, you don't need to use the Network
Server and Network Client.

Try following the "embedded" path in
http://db.apache.org/derby/docs/10.15/getstart/twwdactivity1_overview.html

It's a lot simpler.

Then when you're more comfortable with Derby you can move up to the
Network Server and its additional administration issues.

Re: Derby newbie - error seen creating 'seconddb' thru ij for network-server Derby

2019-11-08 Thread Rick Hillegas
A basic server policy (which you should customize) can be found in the 
Derby Security Guide at 
http://db.apache.org/derby/docs/10.15/security/rsecbasicserver.html It 
is also located in the bin distribution at 
demo/templates/serverTemplate.policy.


Hope this helps,

Better specify separately the security policy for the database.

Include on the command line

-Djava.security.manager -Djava.security.policy=$DERBY_HOME/server.policy"

Maybe there is in the derby demo directory an example.

Hi,

This sounds like it might be a Java permissions error as you are using Open JDK 
11. If you look in the derby.log file located in $DERBY_HOME it will give an 
indication. Post the content of it here.

Derby newbie - error seen creating 'seconddb' thru ij for network-server Derby

2019-11-07 Thread Banibrata Dutta
Hi Folk,

Trying to use Derby for the first time. I am not an expert Java developer
but dabbling for learning me some. I followed the official Derby
instructions for installing the latest Derby on my freshly minted Lubuntu
(lighter Ubuntu using LXDE) 64-bit 18.04.3 setup, with OpenJDK11 (default).

Have started Derby in network server mode like this:
$ java -jar $DERBY_HOME/lib/derbyrun.jar server start

And then trying to using ij to create the database like this:
$ ij
ij version 10.15
ij> CONNECT 'jdbc:derby://localhost:1527/seconddb;create=true';
ERROR XJ041: DERBY SQL error: ERRORCODE: 4, SQLSTATE: XJ041, SQLERRMC:
Failed to create database 'seconddb', see the next exception for
details.::SQLSTATE: XBM01::SQLSTATE: XJ001
ij>

Trying to read around, there are suggestions to look into derby.log file,
but I found none so far. What gives ? How to proceed ? Didn't find any
general troubleshooting instructions in the docs. Tried the FAQ, but no
obvious clues.

cheers,
B
