ColdFusion Exposed Services are a series of Web Services that are available as a new core feature in ColdFusion 9, that expose many of its in built capabilities, so that other languages and technologies can take advantage of them. These Web Services can be consumed as either SOAP based Web Services, or as REST Web Services, depending on what is the best fit for your system.

The following capabilities are exposed through the ColdFusion as a Service Web Services: • Creating PDFs from HTML • Editing exisinting PDFs, including: • merging PDFs • deleting pages • extracting pages • creating thumbnails • adding watermarks • processing DDX • Manipulating Images, including: • drawing on Images • croping • scaling • Retrieving meta data fr om Images • Sending and r eceiving Email • Generating Graphical Charts. By default,ColdFusion as a Service is not set up to be publicly available, for security reasons. To that end, we will need to go into the ColdFusion Administrator to enable access to these Web Services and set up a user who has access to the ColdFusion Web Services, and grant them access. To create this user, point your browser to, and log in with the password you set up when you first installed ColdFusion.

(We will assume that your ColdFusion install has been set up locally from here on in.) Navigate to Security >User Manager through the left hand side menu. Click the 'Add User Button to open the form to add a User. Under 'User Authentication, fill in the user and password fields with 'cfaas'. This will create a new user named 'cfaas' with a password of 'cfaas'. At a later date you may wish to change this to something more secure, but this serves well for demonstrative purposes. At the bottom of the page is a section entitled 'Exposed Services, in which we want to move all the services from 'Prohibited Services to 'Allowed Services. This gives our user 'cfaas' access to all the Services that ship with ColdFusion.

Hit 'Save' when this is complete to save the user. You have now successfully created the user for accessing the ColdFusion as a Service Web Services. The administration section named 'Allowed IP Addresses'can also be used to limit the IP addresses the ColdFusion Services can be accessed from. Depending on your set up, you may need to set up access to the IP address the request is coming from.

To generate the Java code to access the ColdFusion Web Services, we run the tool 'wsimport' that comes with the Java SDK from the root of our Java project. There is an assumption that the Java source with be in a 'src' directory, and the compiled.class files will be in a 'bin' directory. By pointing this tool at Web Services, it will generate all the Java code that is required to interact with the ColdFusion Web Services. If you are using ANT or Maven to build your Java projects there are integrated tasks for both of these build tools for executing wsimport against Web Services. Since there are several end points for interaction with ColdFusion we will have to do this several times. Also, since ColdFusion Services share components, it is easier to generate the Java code into separate packages for each service, than to use the default generated packages.

For more information on wsimport and consuming Web Services with Java, see. First thing we will do is generate the required Java source for the Document package, like so: wsimport -d bin/ -s src/ -p com.coldfusion.document This will create the required Java code to access the Document ColdFusion Web Service. One of the easiest ways of creating a brand new PDF Document is by converting an HTML document into a PDF via ColdFusion's Document Web Service. If you browse to you will get a basic view of the methods that are available on this Web Service, and also the arguments that you are able to take advantage of when calling this Web Service. Except for 'serviceusername' and 'servicepassword', the Document Web Service's arguments corresponds directly to a ColdFusion Tag called 'cfdocument', for which the documentation can be found You can see there are a variety of options for generating a PDF from HTML, which give us a lot of control over what gets generated in our PDF.

Let us attempt to generate a simple 'Hello World!' First we will write some HTML: <a href='String html = '<html>' + '<head>' + '<title>Hello World!' + '<head>' + '<body>' + '<p>Hello World!' + ' + ';'>String html = '<html>' + '<head>' + '<title>Hello World!'

+ '<head>' + '<body>' + '<p>Hello World!' + ' + ' We create a new DocumentService, and request a Document object from it: DocumentService service = new DocumentService(); Document document = service.getDocumentCfc(); There are a wide variety of parameters that can be passed into the 'document.generate()' method, but there are only a few that we are concerned with at the moment: • serviceUsername - this is the username for our ColdFusion as a Service User. • servicePasswor d - this is the passwor d for our ColdFusion as a Service User. • content - the HTML content we ar e passing through. Pass 'null' into the arguments of the ColdFusion Web Service methods in which you wish to use the defaults values. String result = document.generate('cfaas', 'cfaas', null, html, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null); System.out.println(result); This will return a String, for example: Which is a URL to a temporary download of the PDF you have generated.
