You can identify Java code errors and locate the source of Java code errors for a Java transformation in the Output window. Java transformation errors may occur as a result of an error in a code entry tab or may occur as a result of an error in the full code for the Java transformation class.
To troubleshoot a Java transformation:
Locate the source of the error.
You can locate the source of the error in the Java snippet code or in the full class code for the transformation.
Identify the type of error.
Use the results of the compilation in the output window and the location of the error to identify the type of error.
After you identify the source and type of error, fix the Java code in the code entry tab and compile the transformation again.
