Form properties are stored as process variables. Just read them using .getVariable("blah") in your service task.

hi,

I want to pass this value to my bean class. and i dont have DelegateExecution in my bean class. so i must have to pass value as parameter.
I can not use .getVariable("blah") there.

Ya i am putting this as parameter like

<serviceTask

id="createLoanRequest"
name="Create loan request" activiti:expression="${loanRequestBean.newLoanRequest(customerName,amount)}"
activiti:resultVariableName="loanRequest">
</serviceTask>

But it is showing me null pointer exception

Caused by: java.lang.NullPointerException

LoanRequestBean.java:39 –> what is on line 39? Without code I can't really guess?

I would think you want to pass the variables, right? Are those two variables actually added to the process instance first?
