How to access the bpm package of the current workflow from java?

To get the companyHome I use this method:

public NodeRef getCompanyHome()

    {
        return nodeLocatorService.getNode("companyhome", null, null);
    }

the spring confuguration is the following:

<bean id="TransformationHandler" class="org.alfresco.transformation.TransformationHandler"          parent="baseJavaDelegate" lazy-init="default" autowire="default" dependency-check="default">
      <property name="nodeService" ref="NodeService" />
      <property name="nodeLocatorService" ref="nodeLocatorService" />
</bean>

when I loop throug the children of a NodeRef I see the root folder structure(I'm not shure I name them right in english): data dictionary, guest catalog, users home space, published and so on. But as I run my code in the workflow I need to get files I attached to the workflow. What is the way to do this? I'm interested in the configuring workflow model too because in the tutorial there are few information about the bpm:package and the bpm:packageItemActionGroup is the only place where the bpm:package can be found. Is this enough: 

<type name="scwf:activitiApprovedNotification">
    <parent>bpm:workflowTask</parent>
    <overrides>
        <property name="bpm:packageItemActionGroup">
            <default>read_package_item_actions</default>
        </property>
    </overrides>
</type>

? So there are two questions: What is the way to access the content of bpm:package and is the provided above part of workflow model enough for this purpose?

The one way to access content of workflow is to write webscript for it. Here is an example of java backed webscript to access some workflow details:

workflowdetails.get.json.ftl

<webscript>
   <shortname>Get Workflow Task</shortname>
   <description>Retrieves all the workflow tasks which are in progress</description>
   <url>/workflow/details</url>
   <format default="json"/>
   <authentication>user</authentication>
   <transaction allow="readonly">required</transaction>
   <lifecycle>public_api</lifecycle>
</webscript>

WorkflowActiveTaskDetails.java

package util.workflow;

public class WorkflowActiveTaskDetails extends DeclarativeWebScript {
    ServiceRegistry serviceRegistry;

    public void setServiceRegistry(ServiceRegistry serviceRegistry) {
        this.serviceRegistry = serviceRegistry;
    }

    protected Map<String, Object> executeImpl(WebScriptRequest arg0, Status status, Cache cache) {
        WorkflowService workflowService = serviceRegistry.getWorkflowService();
        NodeService nodeService=serviceRegistry.getNodeService();
        JSONArray arr = new JSONArray();
        Map<String, Object> model = new HashMap<String, Object>();

        WorkflowTaskQuery tasksQuery = new WorkflowTaskQuery();
        tasksQuery.setTaskState(WorkflowTaskState.IN_PROGRESS);
        tasksQuery.setActive(true);
        List<WorkflowTask> tasks = workflowService.queryTasks(tasksQuery);

        for(int i=0;i<tasks.size();i++) {
            JSONObject jsondata = new JSONObject();
            Map<QName, Serializable> properties= tasks.get(i).getProperties();
            try {
                Date dueDate=tasks.get(i).getPath().getInstance().getDueDate();
                jsondata.put("duedate", dueDate!=null?dueDate.toString().split(" ")[0]:"");
                jsondata.put("priority",tasks.get(i).getPath().getInstance().getPriority());    jsondata.put("initiator",nodeService.getProperty(tasks.get(i).getPath().getInstance().getInitiator(),ContentModel.PROP_FIRSTNAME));
                jsondata.put("description",properties.get(WorkflowModel.PROP_DESCRIPTION));
                arr.put(jsondata);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
        model.put("data", arr);
        return model;
    }
}

workflowdetails.get.json.ftl

{data}

Bean configuration:

<bean id="webscript.util.workflow.WorkflowActiveTaskDetails.get" class="util.workflow.WorkflowActiveTaskDetails" parent="webscript">
    <property name="serviceRegistry" ref="ServiceRegistry" />
</bean>

And hit this URL: http://localhost:8080/alfresco/service/workflow/details

You will get response like

[{"initiator":"test5","description":"Test Workflow","priority":2,"duedate":"2014-03-29"},{"initiator":"test5","description":"Test Workflow2","priority":1,"duedate":"2014-03-31"}]
