Yeah it's meant as a low friction way to get database access for utilities or games etc..

Thanks

Well it's designed to be a simple and easy to use as possible with no extra dependencies required.  It can do most of what the "big boys" do but without all the extra frameworks and complexity.

Give it a try a and let me know what you think!

Thanks!
Hi everybody!

Persism is a wood simple, auto discovery, auto configuration, and convention over configuration ORM (Object Relational Mapping) library for Java.

Grab it from here: https://github.com/sproket/Persism

You can read all about it here: https://sproket.github.io/Persism/

Includes a getting started guide, javadoc and code coverage report.

I’m working on getting up on Maven central but for now you can install it locally or use ANT or your IDE project.

I have near 100% code coverage and over 130 unit tests running across all the supported database types.

Supported DBs: MSSQL (JTDS as well), Oracle, MySQL, Firebird, H2, HSQLDB, PostgreSQL, Derby and SQLite.

It only takes me an hour or 2 to add a new DB into the unit tests so if there are additional ones you’d like to support let me know!

Thanks to everyone for their interest!
Good to know. But I'm on Java 6 so I should be good.

Hi All,

I tried to use a Box in my BoxLayout and it lays out OK but I can't seem to change it's color. Any ideas?

Hi all,

I'm using a script engine in my game and I'm passing to the bindings some objects which I don't want modified. For example I don't want a script to do something like this:

player.name = "whatever";

So I created a ReadOnly interface for this object (getters only) which I pass to the bindings but the setters are still accessible.

Any ideas? Maybe the solution is to make a copy of the objects?

Found the problem. I was missing the base action servlet configurations in my struts-config.xml. doh!

Hi all,

I'm trying to setup a project to test out velocity. Everything seemed ok until I added toolbox.xml to my WEB-INF folder. Now when I launch my main page i get:



I'm sure it's because I'm missing something but I'm not sure what.

This is what my toolbox.xml looks like:



Any ideas?

TIA

Sorry, what I mean is: How do you have checkboxes in a data table so that the user can select multiple rows and then submit for some kind of operation on those selections?

Hi All,

I've been working through jsf using Sun Studio Creator and I've able to get my web application running quite well but I'm stuck on how to use checkboxes in a data table. I have a list from a rowset and I'd like the user to be able to select certain rows to perform an operation (say delete).

I found one thread about this on the java forums:
Java Forums (checkbox in data table)

But I still don't get how it works. Has anyone done this? Is there an example out there somewhere?

TIA
