Input output extension

i am trying to define the inputOutput variable like this:

        <camunda:inputParameter name="c">5</camunda:inputParameter>
        <camunda:inputParameter name="d">10</camunda:inputParameter>
        <camunda:inputParameter name="e">2</camunda:inputParameter>

in the XML representation of the process

but i’m getting an error while calling it in JavaDelegate class.

public void execute(DelegateExecution execution) throws Exception {
var1= (Long) execution.getVariable(“c”);
var2= (Long) execution.getVariable(“d”);



Please do not open several threads for the same topic. I’m sure @thorben will answer your question in your previous thread as soon there is time for that.
