Why are you using the form properties here? Are you using explorer somehow with a custom form property type?

If you set the variable like that, you will be able to retrieve it using runtimeService.getVariable(), but if you want to use it with form properties, you need custom form properties…

I was using the activiti explorer only. So I found the solution by declaring the custom bean "roleInfo" in "\webapps\activiti-explorer\WEB-INF\activiti-standalone-context.xml".
<blockcode>
<bean id="roleInfo" class="com.confluxsys.DemoCertification.RoleDTO" />
</blockcode>
Is it the correct way to do it ?

The bean has be known by the Spring Context. So for the Activiti Explorer this could be done the way you did it.

Is there a better way to do it as over time my implementation might change and it may be difficult to keep a track of all the variables and their implementing classes?

Thanks in advance

Not if you want to use pojo's as process variables. An alternative is using primitive values here instead of objects.
