Render an interactive PDF form by using the Forms API (Java):
Include project files
Include client JAR files,
such as adobe-forms-client.jar, in your Java project’s class path.
Create a Forms Client API object
Specify URI values
Create a URLSpec object
that stores URI values by using its constructor.
Invoke the URLSpec object’s setApplicationWebRoot method
and pass a string value that represents the application’s web root.
Invoke the URLSpec object’s setContentRootURI method
and pass a string value that specifies the content root URI value.
Ensure that the form design is located in the content root URI.
If not, the Forms service throws an exception. To reference the
repository, specify repository:///.
Invoke the URLSpec object’s setTargetURL method
and pass a string value that specifies the target URL value to where
form data is posted. If you define the target URL in the form design,
you can pass an empty string. You can also specify the URL to where
a form is sent in order to perform calculations.
Attach files to the form
Create a java.util.HashMap object
to store file attachments by using its constructor.
Invoke the java.util.HashMap object’s put method
for each file to attach to the rendered form. Pass the following
values to this method:
A com.adobe.idp.Document object that contains
the file attachment.
Note: Repeat this
step for each file to attach to the form. This step is optional
and you can pass null if you do not want to send file attachments.
Render an interactive PDF form
Invoke the FormsServiceClient object’s renderPDFForm method
and pass the following values:
A string value that
specifies the form design name, including the file name extension.
If you reference a form design that is part of a LiveCycle application,
ensure that you specify the complete path, such as Applications/FormsApplication/1.0/FormsFolder/Loan.xdp.
A com.adobe.idp.Document object that contains
data to merge with the form. If you do not want to merge data, pass
an empty com.adobe.idp.Document object.
A PDFFormRenderSpec object that stores run-time
options. This is an optional parameter and you can specify null if
you do not want to specify run-time options.
A URLSpec object that contains URI values
that are required by the Forms service.
A java.util.HashMap object that stores file
attachments. This is an optional parameter and you can specify null if
you do not want to attach files to the form.
The renderPDFForm method
returns a FormsResult object that contains a form
data stream that must be written to the client web browser.
Write the form data stream to the client web browser
Create a com.adobe.idp.Document object by
invoking the FormsResult object ‘s getOutputContent method.
Get the content type of the com.adobe.idp.Document object
by invoking its getContentType method.
Set the javax.servlet.http.HttpServletResponse object’s content
type by invoking its setContentType method and
passing the content type of the com.adobe.idp.Document object.
Create a javax.servlet.ServletOutputStream object
used to write the form data stream to the client web browser by
invoking the javax.servlet.http.HttpServletResponse object’s getOutputStream method.
Create a java.io.InputStream object by invoking
the com.adobe.idp.Document object’s getInputStream method.
Create a byte array and populate it with the form data stream
by invoking the InputStream object’s read method
and passing the byte array as an argument.
Invoke the javax.servlet.ServletOutputStream object’s write method
to send the form data stream to the client web browser. Pass the byte
array to the write method.
