Journey Manager is written in JavaJava is a programming language that produces software for multiple platforms. When a programmer writes a Java application, the compiled code (known as bytecode) runs on most operating systems (OS), including Windows, Linux and Mac OS. Java derives much of its syntax from the C and C++ programming languages. and runs on Java Virtual MachineJava Virtual Machine (JVM) is a software-based machine that runs Java programs. It can be installed on several different operating systems, including Windows, OS X, and Linux. JVMs allow Java apps to run on almost any computer. (JVM). Manager provides extensive support for using GroovyGroovy is a powerful scripting language which runs on the Java Virtual Machine. Across theTemenos Journey Manager platform, Groovy is used to create services in Manager. These services are primarily used to create plug-in style systems that interact with Manager. language, which enables developers to quickly implement business and integration logic without having to deploy custom code as jar files and restart Manager servers.

Groovy has the following benefits, over other scripting languages, that make it the right candidate for Manager:

• Groovy is a dynamic scripting language, which allows developers to implement and customize Groovy scripts without re-compiling and re-deploying Manager applications. The scripts can be stored as files or as objects in the DBA database is a data structure that stores organized information. Most databases contain multiple tables, which may each include several different fields. For example, a company database may include tables for products, employees, and financial records. Each of these tables would have different fields that are relevant to the information stored in the table.. Manager extensively utilizes Groovy scripts to implement Transact Services. It has the advantage that the service does not need to be compiled nor the containing component rebuilt prior to use. For more information, see the service definitions extension points listed below.
• Groovy is developed for Java, so it runs on JVM and most of the code written in Java will compile and work as expected when you try to run it as a Groovy script. It seamlessly and transparently integrates and is compatible with Java and any third-party libraries.
• Groovy is Java syntax compatible, so learning Groovy won’t be challenging for someone who knows Java already.
• Groovy has concise, brief and direct syntax, which makes it easy to learn, develop and read the code. It requires less lines of code to implement the same functionality as compared with Java.
• Groovy has native support for markup languages, such as XML and HTML, with which developers can quickly create sophisticated application logic and in less code. It also enables the definition and manipulation of many types of data assets, which is handy in data preparation and manipulation.
• Groovy comes with integrated support for converting between Groovy objects and JSONJSON (JavaScript Object Notation) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays..
• Groovy is a testing-oriented development language, which is great for writing concise and maintainable tests, and for all your build and automation tasks.
• Groovy has powerful features - closures, builders, runtime and compile-time meta-programming, functional programming, type inference, and static compilation - which allows developers to implement complex application rules in a concise and well defined way.

Manager uses service definitions, which provide Groovy extension points for the following service types.

• Delivery Process.
• Dynamic Data.
• Form Prefill.
• Form Saved Processor.
• Groovy Service.
• Receipt Number.
• Scheduled Service.
• Submission Complete Processor.
• Submission Preprocessor.
• Task Expiry.

All these services have Groovy tab that allows developers to write a Groovy script to implement specific requirements.

The script can be tested using the Unit Test tab, which significantly speeds up the development process and helps to find most of the errors before making use of this service.
