How to trigger a workflow process programmatically?

Question

Hi Team,I have written a workflow process (com.mycompany.workflow.MyWorkflowProcess) by implementing com.day.cq.workflow.exec.WorkflowProcess. I have to trigger this workflow process programmatically? The only input I got is the workflow process (i.e. com.mycompany.workflow.MyWorkflowProcess) not even the model of the workflow in which it is used.My requirement is -Author will select the workflow from the drop-down (which is as same as the Process drop-down in the workflow Process Step)From the drop-down I will get the symbolic name of the process like com.mycompany.workflow.MyWorkflowProcess.I have to trigger this workflow programmatically.Please help me in this.Thanks,AryA.

There are only 2 methods (not counting the Deprecated one) exposed in the WorkFlowSession Class that starts a workflow:

`Workflow`	`startWorkflow(WorkflowModel model, WorkflowData data)` Start a new `Workflow` instance with the given `WorkflowModel` and `WorkflowData`.
`Workflow`	`startWorkflow(WorkflowModel model, WorkflowData data, Dictionary<String,String> metaData)` Deprecated. It's recommended to use `#startWorkflow(WorkflowModel, WorkflowData, Map instead.`
`Workflow`	`startWorkflow(WorkflowModel model, WorkflowData data, Map<String,Object> metaData)` Start a new `Workflow` instance with the given `WorkflowModel`, `WorkflowData` and `meta data`.

Therefore you need a WorkflowModel and data,

In your use case - you need these as input - else it will not work.

Ya. I have seen that article. In that they are invoking the OSGi service and passed the model as input then started the workflow using the model path. But in my case, I have to trigger the workflow directly with the input, com.my company.workflow. MyWorkflowProcess which implements WorkflowProcess. Any idea?
