Creating a single jarfile with all dependencies

Sometimes, you do not have the option to deploy to an applicationserver, and it is necessary to release a single stand-alone jar.

For this, we can use the excellent one-jar code, or, the maven one-jar plugin.
A simple link to the documentation should suffice. It is exactly what you want as it supports it's own classpath, ensuring that multiple files can exist with the same name (of course, it'll warn you about that, but).

It's much better then the normal maven assembly plugin, as it gives all sorts of problems.

You can then use the normal java -jar myOneJar.jar to start your program.
Of course, if you're allowed to use maven, you can let maven set up the classpath for you... But that will be in a different post.

Spring's conditional annotation with properties

Spring has a nice @Conditional annotation, to have the option to have beans be available in the context depending a specific condition (Of course, this can also be realized by using @Configuration objects, but that's a different post). Ideally, we'd have the option to have a condition evaluate to true or false depending on a property. Sadly, Spring does not support that out of the box. Googling and looking around gives a partial solution, but the complete one here, so we won't forget: /** * Components annotated with ConditionalOnProperty will be registered in the spring context depending on the value of a * property defined in the propertiesBeanName properties Bean. */ @Target({ ElementType.TYPE, ElementType.METHOD }) @Retention(RetentionPolicy.RUNTIME) @Conditional(OnPropertyCondition.class) public @interface ConditionalOnProperty { /** * The name of the property. If not found, it will evaluate to false. */ String value(); /** * if the p...

OSGI insights without sonar

So I was on a project without sonar. Oh my. Well, it was an OSGI project, so the problems couldn't be that bad, right? But how good were they (and what things were bad?) I found Stan4j , a code analysis tool for eclipse, which draws nice graphs and can handle osgi pretty well it seems. Now I can see that dependencies/bundle names aren't properly aligned (even though OSGI doesn't complain), etc.

JPA and transactions

So I was working with JPA and transactions. Consider the following: In bean 1, with implicit TX 1, managed entities are loaded/created,and returned in bean 2, with implicit TX 2, entities are modified in bean 3, with NO TX, bean 1 is called, and the results are passed to bean 2. and bean 4 is similar to bean 3, but with it's own transaction, TX3 What happens when bean 3 finishes: are the entities updated? What happens when bean 4 finishes, are the entities updated? The answer to this is simple; entities are managed through a persistance context. That context is tied to the transaction. So in bean 2, there is a difference. When called from bean 3, it runs in a different transaction then bean 1, and thus a different persistance context, and thus the entities are not managed 'by this transaction'.When called from bean 4, it all runs in the same transaction, TX3, and the results are persisted.
