I have listed down some of the common differences between tJava, tJavaRow and tJavaFlex component.

 

Operations tJava tJavaRow tJavaFlex
Use component to integrate your custom Java code Yes Yes Yes
It will be executed first but only once in the subjob. Yes No -
It requires Input Flow No Yes No
It Requires Output Flow No If output Schema Defined If output Schema Defined
It can be used as Start of the Job Yes No Yes
It can be used as a separate subjob Yes No Yes
It accepts Main Flow or Iterator Flow Both Only Main Both
It has three Java code parts (start, main, end) No No Yes
It will Auto propagate Data No No Yes

 

tJava advantage: this component can be use as trigger component, At start of the job at end of the job.

tJavaRow : this component required main flow so it can be used at end of the Sub Job but not at the start of subjob.

tJavaFlex: this component holds capabilities of tJava & tJavaRows you can use this component for row generation, or at start of job, or at then end of sub job. or individual  subjob.  It gives you ability to auto propagate data.
