Chapter 5. Using Java in Talend

Java is a hugely popular and incredibly rich programming language. Talend is a Java code generator which makes use of many open source Java libraries, so this means that Talend functionality can easily be extended by integrating Java code into Talend jobs.

This chapter contains recipes that show some of the techniques for making use of Java within Talend jobs.

Performing one-off pieces of logic using tJava
Setting the context and globalMap variables using tJava
Adding complex logic into a flow using tJavaRow
Creating pseudo components using tJavaFlex
Creating custom functions using code routines
Importing JAR files to allow use of external Java classes

Barton

Rick Barton is a freelance consultant who has specialized in data integration and ETL for the last 13 years as part of an IT career spanning over 25 years. After gaining a degree in Computer Systems from Cardiff University, he began his career as a firmware programmer before moving into Mainframe data processing and then into ETL tools in 1999. He has provided technical consultancy to some of the UKs largest companies, including banks and telecommunications companies, and was a founding partner of a Big Data integration consultancy. Four years ago he moved back into freelance development and has been working almost exclusively with Talend Open Studio and Talend Integration Suite, on multiple projects, of various sizes, in UK. It is on these projects that he has learned many of the lessons that can be found in this, his first book.
