A few constants... the USER_ID must match a user's id in the database; the GROUP_ID must be 1.

    public static final int USER_ID = 1;
    public static final int GROUP_ID = 1;

Inserting a project and getting the resulting project id...

    //After the insert, we'll need the project's id
    ArrayList<String> meta = new ArrayList<String>();
    meta.add("id");
    api.setTransactionMeta(meta);

    // The minimum number of fields for a successful project insert
    DataRecord record = new DataRecord();
    record.setName("project");
    record.setAction(DataRecord.INSERT);
    record.addField("title", title);
    record.addField("shortDescription", "API Test Project short description");
    record.addField("requestDate", new java.util.Date());
    record.addField("enteredBy", USER_ID);
    record.addField("modifiedBy", USER_ID);
    record.addField("groupId", GROUP_ID);
    api.save(record);

    int newProjectId = api.getResponseValueAsInt("id");

Querying the projects and requesting the "id" and "title" fields in return; filters can optionally be set (based on the capabilities of the ProjectList class):

    ArrayList<String> meta = new ArrayList<String>();
    meta.add("id");
    meta.add("title");
    api.setTransactionMeta(meta);

    DataRecord record = new DataRecord();
    record.setName("projectList");
    record.setAction(DataRecord.SELECT);
    // Set the filters to query by
    record.addField("projectId", "$C{project.id}");
    record.addField("projectsForUser", "$C{user.id}");
    
    api.save(record);
    
    // Review the returned data (untested)
    ArrayList<DataRecord> projectObjects = api.getRecords();
    for (DataRecord projectObject : projectObjects) {
      DataRecord partialProject = projectObject;
      // do something
    }

Deleting a project (must have id):

    // Construct a delete request
    DataRecord record = new DataRecord();
    record.setName("project");
    record.setAction(DataRecord.DELETE);
    record.addField("id", partialProject.getId());
    api.save(record);

Project features can be set on project insert because a project must have features. If not specified, then defaults are used.

After a project has been inserted, the features must be updated using projectFeatures. The project api does not update the features.

DataRecord record = new DataRecord();
record.setName("projectFeatures");
record.setAction(DataRecord.UPDATE);
record.addField("id", projectId);
record.addField("modified", new Date());
record.addField("modifiedBy", USER_ID);
record.addField("showCalendar", true);
record.addField("showTickets", true);
record.addField("showDiscussion", false);
record.addField("showPlan", true);
record.addField("showLists", false);
record.addField("showDocuments", false);
api.save(record);
