Java Function
Any public Java class method can be used for fieldwise transformation.
This provides a wide range of transformation possibilities. During the
transformation process, the method is processed with the input of each
row of the transform.
Parameters
Class
The Java class (i.e. its constructor). It can be static.
Method
The name of the public method in the Java class. The method can have one or several input parameters
and a return value, all of simple data types.
The input fields of the function are assigned to the parameters of the
Java class constructor and/or the Java method: the first input is
assigned to the first parameter, the second input to the second
parameter, etc.
Each input field requires the following specifications:
Input
The name of the input field (as for other functions in a FieldTransform).
Type
A data type that has to match the corresponding parameter type in the Java method. If specified, the input
field is converted to this data type. The possible values are: string (default), double, int, byte, float, short,
long, and object.
Target
class: for input fields of the constructor class
method: for parameters of the method class
If the Java class is not part of the JRE (like e.g. java.lang.String), it has
to be copied to the Jedox Integrator installation. To do this, perform the
following actions:

Stop the JedoxSuiteTomcatService service
Copy the .class or .jar file of the Java class to the
.\tomcat\webapps\etlserver\WEB-INF\lib_external folder.
Start the JedoxSuiteTomcatService service
For the generation of the Java class file, the same JDK version used for
the Jedox Integrator installation should be used to avoid compatibility
issues.
