Hi,
What don't you just put your condition in your tJava row???
If(){
....
} else if (){
}
...

You can use a context var inside your tjavarow like this :
context.myvar = input_row. (in your case : application.id if I understand)

On your "if" link you can use the context var to test your choice :
"myapplication1".equals(context.myvar)

Hi
The runif trigger is fired after the tJavaRow works, that's why you only get the last record. In this case, you need to iterate each row, for example:
....tMap--out1---tFlowToiteate--iterate---tFixedFlowInput--main--tJavaRow---runIf---tJava_2
on tFixedFlowInput, generate each row of out1, for example, add two columns on the schema:
key:value
id Integer)globalMap.get("out1.id") //assuming the data type of id column is integer/int type.
name String)globalMap.get("out1.name") //assuming the data type of name column is String type.
on tJavaRow: do as Xavier MOUCHOT mentioned.
