ODI 12c - Data Input Experts

Back in the olde days of OWB I blogged about a few utilities (see here) that were useful for collecting user input data in custom flows, users build such flows to implement accelerators to take the mundane tasks out of common activities. In ODI you can also use groovy SwingBuilder, this let's you build useful dialogs very easily. I posted some examples such as the one below for model creation in ODI and a launchpad example;

The utilities for OWB I mentioned in the blog are just basic java classes that were invoked from OWB via tcl/jacl. These utilities are written in java and can still be used from ODI via groovy. Still as useful, still as functional. Let's see how we call them now!

The required JARs need to be put on the groovy classpath, which is under the ODI IDE's Tools->Preferences option, and then under ODI->System->Groovy and set the groovy classpath to include jexpert.jar, tcljava.jar and jacl.jar. For example I have the following referencing the JARs from my 11gR2 database which has the OWB code;

  • D:\app\dallan\product\11.2.0\dbhome_1\owb\lib\int\jexpert.jar;D:\app\dallan\product\11.2.0\dbhome_1\owb\lib\int\tcljava.jar;D:\app\dallan\product\11.2.0\dbhome_1\owb\lib\int\jacl.jar

I can then launch the shuttle dialog for example as follows;

  1. import oracle.owb.jexpert.ShuttleObjects
  2. arrayOfString = [ "PRODUCT_ID", "PRODUCT_NAME", "PRODUCT_COLOR", "PRODUCT_DESC", "PRODUCT_LONG_DESC", "CATEGORY_ID", "CATEGORY_NAME", "CATEGORY_DESCRIPTION", "SUBCATEGORY_ID", "SUBCATEGORY_NAME", "SUBCATEGORY_DESCRIPTION" ]
  3. sels = ShuttleObjects.getselection("Select dimension levels", "Select columns to identify levels:", "Columns:", "Levels", (String[]) arrayOfString.toArray())

  4. println sels

I can use the returned variable sels and do whatever ODI stuff I need, you can see the code above executed from within ODI and the dialog appearing with the information;

Likewise the data entry dialog works as is, when that dialog is executed from groovy, just like in OWB we can get the information displayed, the user can enter data, we can collect it and action it in our groovy using the ODI SDK;

The blog on the 12c mapping SDK here has a good SDK reference table that gives you pointers for all parts of the product into the SDK areas. This is definitely a handy one to bookmark, I often use it myself. Learn some scripting it'll help save you are your teams a lot of time.
