Samples and examples in this document are only for AEM Forms on JEE environment.

The Forms service renders HTML forms in response to an HTTP request from a web browser. When rendering an HTML form, the Forms service can reference a custom CSS file. You can create a custom CSS file to meet your business requirements and reference that CSS file when using the Forms service to render HTML forms.

The Forms service silently parses the custom CSS file. That is, the Forms service does not report errors that may be encountered if the custom CSS file does not comply with CSS standards. In this situation, the Forms service ignores the style and continues with the remaining styles in the CSS file.

The following list specifies styles that are supported in a custom CSS file:

  • Class level selector-style pairs: If present in a custom CSS file, selectors used in the HTML form as class styles are used. Unused class styles are ignored.
  • Identifier level selector-style pairs: All identifier styles are used if they are used in the HTML form.
  • Element level selector-style pairs: All element styles are used if they are used in the HTML form.
  • Style Priority: Style priority (like important) is supported and can be used in a custom CSS file.
  • Media Type: One or more selector-style pairs can be wrapped in @media style to define the media type. The Forms service does not check whether the specified media type is supported. The media type specified in the custom CSS file is merged in the HTML form.

You can retrieve a sample CSS file by using the FormsIVS application. Upload the form, select it in the Test Form Design page, and click GenerateCSS. You are not required to set the HTML transformation type before clicking the button. Next select save. You can edit this CSS file to meet your business requirements.

NOTE
Before rendering an HTML form that uses a custom CSS file, it is important that you have a solid understanding of rendering HTML forms. (See Rendering Forms as HTML.)

Summary of steps summary-of-steps

To render an HTML form that uses a CSS file, perform the following tasks:

  1. Include project files.
  2. Create a Forms Java API object.
  3. Reference the CSS file.
  4. Render an HTML form.
  5. Write the form data stream to the client web browser.

Include project files

Include necessary files in your development project. If you are creating a client application by using Java, include the necessary JAR files. If you are using web services, ensure that you include the proxy files.

Create a Forms Java API object

Before you can programmatically perform an operation supported by the Forms service, you must create a Forms client object.

Reference the CSS file

To render an HTML form that uses a custom CSS file, ensure that you reference an existing CSS file.

Render an HTML form

To render an HTML form, specify a form design that was created in Designer and saved as an XDP file. Select an HTML transformation type. For example, you can specify the HTML transformation type that renders a dynamic HTML for Internet Explorer 5.0 or later.

Rendering an HTML form also requires values, such as URI values needed to render other form types.

Write the form data stream to the client web browser

When the Forms service renders an HTML form, it returns a form data stream that you must write to the client web browser to make the HTML form visible to the user.

Creating Web Applications that Renders Forms

Render an HTML form that uses a CSS file using the Java API render-an-html-form-that-uses-a-css-file-using-the-java-api

Render an HTML form that uses a custom CSS file by using the Forms API (Java):

  1. Include project files

    Include client JAR files, such as adobe-forms-client.jar, in your Java project鈥檚 class path.

  2. Create a Forms Java API object

    • Create a ServiceClientFactory object that contains connection properties.
    • Create a FormsServiceClient object by using its constructor and passing the ServiceClientFactory object.

  3. Reference the CSS file

    • Create an HTMLRenderSpec object by using its constructor.
    • To render the HTML form that uses a custom CSS file, invoke the HTMLRenderSpec 辞产箩别肠迟鈥檚 setCustomCSSURI method and pass a string value that specifies the location and name of the CSS file.

  4. Render an HTML form

    Invoke the FormsServiceClient 辞产箩别肠迟鈥檚 (Deprecated) (Deprecated) renderHTMLForm 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 Forms application, ensure that you specify the complete path, such as Applications/FormsApplication/1.0/FormsFolder/Loan.xdp.
    • A TransformTo enum value that specifies the HTML preference type. For example, to render an HTML form that is compatible with dynamic HTML for Internet Explorer 5.0 or later, specify TransformTo.MSDHTML.
    • 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.
    • The HTMLRenderSpec object that stores HTML run-time options.
    • A string value that specifies the HTTP_USER_AGENT header value, such as Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322).
    • A URLSpec object that stores URI values required to render an HTML form.
    • 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 (Deprecated) renderHTMLForm method returns a FormsResult object that contains a form data stream that must be written to the client web browser.

  5. 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 辞产箩别肠迟鈥檚 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.h\ttp.HttpServletResponse 辞产箩别肠迟鈥檚 getOutputStream method.
    • Create a java.io.InputStream object by invoking the com.adobe.idp.Document 辞产箩别肠迟鈥檚 getInputStream method.
    • Create a byte array and populate it with the form data stream by invoking the InputStream 辞产箩别肠迟鈥檚 read method and passing the byte array as an argument.
    • Invoke the javax.servlet.ServletOutputStream 辞产箩别肠迟鈥檚 write method to send the form data stream to the client web browser. Pass the byte array to the write method.

    • To render the HTML form that uses a custom CSS file, invoke the HTMLRenderSpec 辞产箩别肠迟鈥檚 setCustomCSSURI method and pass a string value that specifies the location and name of the CSS file.

  4. Render an HTML form

    Invoke the FormsService 辞产箩别肠迟鈥檚 (Deprecated) renderHTMLForm 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 Forms application, ensure that you specify the complete path, such as Applications/FormsApplication/1.0/FormsFolder/Loan.xdp.
    • A TransformTo enum value that specifies the HTML preference type. For example, to render an HTML form that is compatible with dynamic HTML for Internet Explorer 5.0 or later, specify TransformTo.MSDHTML.
