How do I get a form entry based on a known id?

This is often needed when you need to relate a frevvo form an  form with another concept your application (e.g. you application has the concept of a report that has an associated frevvo form form). In this case you will store the form id somewhere and when needed fetch the form entry to embed it in your page, delete it, etc.
Here  Here is how you get the for a form entry (in fact any entry):

    FormTypeEntry ftEntry = ...;
    String formId = ftEntry.getId();

    FormTypeEntry ftEntry = fs.getEntry(formEntryUrl, FormTypeEntry.class);

How do I delete a form (or any other entry)?

By calling the delete method on the FormTypeEnty.

    FormTypeEntry ftEntry = ...;
    ftEntry.delete();

How do I create a new form?

First you have to get a hold of the form feed from an existing application. See How do I get the list of all forms for a given application?

    FormsService fs = ...;
    ApplicationEntry appEntry = ...;
    FormTypeFeed ftFeed = appEntry.getFormTypeFeed();
    FormTypeEntry newEntry = ftFeed.createEntry();
    newEntry.setTitle(new PlainTextConstruct("MyForm"));
    newEntry.setSummary(new PlainTextConstruct("MyForm Description"));
    newEntry = ftFeed.insert(newEntry);

How do I create a new form using an existing one as a template?

The only difference between creating a new form and creating a new one based on an existing form is that instead of using the entry created by calling 'ftFeed.createEntry()' you will be using an existing form entry. Find an existing form entry, update its name and description and use that entry to insert into a feed. Do not override the entry id otherwise the insert will fail.

    FormsService fs = ...;
    ApplicationEntry appEntry = ...; // find app entry
    FormTypeEntry ftEntry = ...; // find template form entry 
    ftEntry.setTitle(new PlainTextConstruct("MyForm"));
    ftEntry.setSummary(new PlainTextConstruct("MyForm Description"));
    FormTypeFeed ftFeed = appEntry.getFormTypeFeed();
    FormTypeEntry newEntry = ftFeed.insert(ftEntry);

How do I

...

copy a form?

It is also possible to download a form using the API similar to the way you can download one from the UI. Consider the following code snippet:Copying entails inserting an existing entry into a feed. The key difference between this case and a regular feed insert() is that the entry being inserted already has an id: this will trigger a copy.

    FormsService// fsget = ...;
    ApplicationEntry appEntry = ...; // find app entry
    the FormTypeEntry you want to copy
    FormTypeEntry ftEntry = ...;
// find
template form entry  // get the FormTypeFeed MediaContentyou mcwill =copy (MediaContent) ftEntry.getContent();TO
    FormTypeFeed MediaSource mstargetFeed = getService().getMedia(mc)appEntry.FormTypeFeed;

   OutputStream formStream = new FileOutputStream("myform_form.zip");
    saveFormToDisk(ms.getInputStream(), formStream);

How do I upload an form into an existing application?

...

 // Perform the copy
    FormTypeEntry copy = ftFeed.Insert(FormType);

How do I download an existing form?

It is also possible to download a form using the API similar to the way you can download one from the UI. Consider the following code snippet:

    FormsService fs = ...;
    ApplicationEntry appEntry = ...; // find app entry
    FormTypeFeedFormTypeEntry ftFeedftEntry = appEntry...getFormTypeFeed(); // find template form InputStreamentry formZipStream
= new FileInputStream("myform_form.zip");  MediaContent mc  MediaStreamSource formMediaSource = new     MediaStreamSource(formZipStream,"application/zip"= (MediaContent) ftEntry.getContent();
    MediaSource ms = getService().getMedia(mc);
    FormTypeEntryOutputStream ftEntryformStream = ftFeed.insert(formMediaSource);

How do I use Self-signed Certificates with the API?

One approach is to modify the client code to accept self-signed certificates, but the recommended method is to use the standard Java mechanisms to trust a self-signed certificate; for example, to add the self-signed certificates to the JRE trusted keystore.

• Use a key tool to create a key
• Used '''installcert.java''' to install the certificate in a trusted keystore
• Save the keystore in the ''jre-home\lib\security'' directory
• Restart the server

How do I set a form's Deployment State?

FormTypeEntry ftEntry = setUpFormType(appEntry);
try {
System.out.println("Default State: " + ftEntry.getDeployState());
ftEntry.setDeployState(DeployState.PRODUCTION);
ftEntry = ftEntry.update();
ftEntry = ftEntry.getSelf();
assertEquals("Should be PRODUCTION state", ftEntry.getDeployState(), DeployState.PRODUCTION);

ftEntry.setDeployState(DeployState.DEVELOPMENT);
ftEntry = ftEntry.update();
ftEntry = ftEntry.getSelf();
assertEquals("Should be DEVELOPMENT state", ftEntry.getDeployState(), DeployState.DEVELOPMENT);

FormTypeFeed ftFeed = appEntry.getFormTypeFeed();
FormTypeEntry newEntry = ftFeed.createEntry();
newEntry.setTitle(new PlainTextConstruct("MyForm123"));
newEntry.setSummary(new PlainTextConstruct("MyForm123 Description"));
newEntry.setVisibility(Visibility.PUBLICTENANT);
newEntry.setDeployState(DeployState.PRODUCTION);
newEntry = ftFeed.insert(newEntry);
assertNotNull(newEntry.getSelf());
assertEquals("Should be PRODUCTION state", newEntry.getDeployState(), DeployState.PRODUCTION);
newEntry.delete(); new FileOutputStream("myform_form.zip");
    saveFormToDisk(ms.getInputStream(), formStream);

How do I upload a form into an existing application?

You can also upload a form that was previously downloaded using the following code snippet:

    FormsService fs = ...;
    ApplicationEntry appEntry = ...; // find app entry
    FormTypeFeed ftFeed = appEntry.getFormTypeFeed();
    InputStream formZipStream = new FileInputStream("myform_form.zip");
    MediaStreamSource formMediaSource = new     MediaStreamSource(formZipStream,"application/zip");
    FormTypeEntry ftEntry = ftFeed.insert(formMediaSource);

Why are deleted submissions showing up in the submissions feed?

The submissions feed will retrieve all type of submissions: submitted, saved, deleted (Deleted submissions are soft deleted meaning they are marked in the database as deleted, but the records are still present in the DB and they will be returned in the SubmissionFeed). The  Submissions UI page, by design, shows only the submissions which are completed.

Let's say you want to sort submissions that are saved versus those that are submitted. You can use the SubmissionEntry.getState() method. This will return the current state of a SubmissionEntry (SAVED or SUBMITTED). You can use this property to distinguish between your submissions.

How do I get a form submission PDF when Save PDF is not enabled?

Using API, you can instantiate each form submission, get the PDF for that instance and then cancel the form instance. Note that the PDF will not show up in the form submission when using this approach as the instance is canceled.

Here is an example API script that will download PDF's for all form submissions to disc:

/ formTypeID of your form. You can get the formTypeId of a form by looking at its Share URL. For example, if your forms Raw URL is: http://localhost:8082/frevvo/web/tn/qa/user/fd/app/_S5QyQQ8GEeKoZPV3UpCRog/formtype/_W03sMA8GEeKoZPV3UpCRog?_method=post&embed=true&locale=, then the part of this URL between formtype/ and ?_method is your formTypeId.
String formTypeId = "_W03sMA8GEeKoZPV3UpCRog";  

// Get the Forms Service.
FormsService service = new FormsService("http", "localhost", 8082, null);
service.login("designer@tutorial", "designerpswd");

// Get Submission Feed
SubmissionQuery q = new SubmissionQuery(service.getFeedURL(SubmissionFeed.class));
q.setFilter("$formTypeId eq " + formTypeId);
q.setOrderby("$updated");  
SubmissionFeed sFeed = service.getFeed(q, SubmissionFeed.class);

int counter = 1;
// Download PDF for each submission
for (SubmissionEntry contact : sFeed.getEntries()) {
       // re-instantiate the form from the submission
       URL fUrl = contact.createFormInstance(null, null);
       // Construct the URL which will generate the PDF
       String pdfUrl = fUrl.toString() + "&print=true&format=pdf";
       String filename = "E:\\myFormPDF" + counter + ".PDF";
       BufferedInputStream in = null;
       FileOutputStream fout = null;
       try
       {
             in = new BufferedInputStream(new URL(pdfUrl).openStream());
             fout = new FileOutputStream(filename);

             byte data[] = new byte[1024];
             int count;
             while ((count = in.read(data, 0, 1024)) != -1)
             {
                    fout.write(data, 0, count);
             }
       }
       finally
       {
             if (in != null)
                    in.close();
             if (fout != null)
                    fout.close();
       }      
       counter ++;
       // Cancel the instance
       Helper.cancelInstance(service, fUrl);    
}
