Accessing Spring Beans from the BIRT Designer

Implementing the org.eclipse.birt.core.ScriptFunctionService

Java Developer Magazine on Ulitzer

Recently I have described methods that can be used to access Spring Beans from the BIRT Engine. These examples are intended to be illustrative and not comprehensive.

In both of these examples I used the BIRT engine to retrieve Spring objects within the scripting environment. In this post I am supplying an example that illustrates how to implement your own menu in the expression builder, so Spring objects can be called within the BIRT Designer. This will allow you to test your report prior to deployment.

In this post:
BIRT 2.3.1 - Adding Functions to the Expression Builder
I described how to implement the org.eclipse.birt.core.ScriptFunctionService. The attached example is an implementation of this extension point. When using this example the expression builder will appear as follows.

Notice that there is now a SpringFunctions sub-category, which provides one method callBean. This method takes a bean name and a method name and expects a returned string. To keep the example simple no arguments are supported and the method must return a string. The plugin.xml looks like the following:

Provided with the example is a deployable J2EE application and the plugin that implements the ScriptFunctionService. See the readme for details on setting up the example. Also note that the deployable plugin is also attached in the example. You will need to add this to your designer and your runtime. This example works with both the Open Source BIRT designer and the Actuate BIRT designer.

Also included is an example report with the following output.

This example is available at Birt-Exchange.

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
