Custom JARs overview

This chapter guides you on how to use Custom JARs with your mapping. To create a Custom JAR file you must be familiar with Java programming and how to create a JAR file, for example using Eclipse.

If you have some self-contained Java code that you need to use several times, within one or several mappings, you can put this Java code into a Custom JAR. If you need to create some advanced Java code for a mapping, using several classes, you can place that Java code in a Custom JAR, even if it is just used once.

JAR stands for Java Archive, JAR is a file format that enables you to bundle multiple files into a single archive file. A JAR file is basically a zip file that contains one or several Java class files in their package folder structure. The source code, that is the .java files, may also be included.
