I have an existing code base that is not packaged at all. The code base is all minor Java programs designed to extend/enhance the functionality of a third party program. The current process is one jar per class, one class per file, no package. I'd like to break out the code-base so each jar file is also a package; this eases my jar pro...
Hi, With Lotus Domino 8.5.1, one can use "standard" Java classes into server side Javascript (embedded into an Xpage), or Java classes available in the WEB-INF/lib folder. For example : var driverClass:java.lang.Class; var driver:java.sql.Driver; var connection:java.sql.Connection; var statement:java.sql.Statement; driverClass = java....

WARNING: see my own answer below. The problem is caused by old Oracle drivers that were present on the classpath in addition to 10.2.0.4. Problem solved. Leaving the rest of this question for posterity. I've been banging my head against the following. Here's a simple POJO distilled from my application code: @Entity @Table(name = "PIGGI...

Any ideas for something speedy? ...
Consider the following two snippets of code: int index = 676; List<String> strings = new ArrayList<String>(); strings.add(index, "foo"); and int index = 676; List<String> strings = new ArrayList<String>(); strings.ensureCapacity(index); strings.add(index, "foo"); In the first case, I'm not surprised to see an IndexOfOutBoundsExcept...

Is it possible to call in some way an EJB deployed on JBoss from a Business Service deployed on BEA AquaLogic Service Bus? Just to precise, I'm not going to call it through Web Service, but through normal EJB call. I would appreciate if anyone has a succesful experience in this matter. ...

Can someone recommend a good, open source, standalone developer tool for querying SQL databases using JDBC and exporting the results to a file? I know a lot of database vendors provide their own tools, but I need one that will allow me to plug in my own custom JDBC driver and work against any database. A GUI is preferable, but not requir...

I want to write a program that will be able to call into my company's bi-weekly conference calls, and record the call, so it can then be made into a podcast.

I think this question may end up being a bit subjective so I'm marking it as CW. My team is interested in developing a new set of "web services" for our projects to use. I put "web services" in air-quotes since the term can mean so many different things. The only thing we really need it to mean is that we can expose some set of APIs to ...
