This sample shows how to send a basic email.

The first lines configure the properties that will be used by the sender. Then you must create the service. You can use the MessagingBuilder to help you to create the service. Finally, the last line sends the email. The specified email is really basic. It only contains the subject, the textual content and the receiver address. The sender address is automatically added to the email by the service based on configuration properties.

public class BasicSample {

    public static void main(String[] args) throws MessagingException {
        // configure properties (could be stored in a properties file or defined
        // in System properties)
        Properties properties = new Properties();
        properties.put("mail.smtp.host", "<your server host>");
        properties.put("mail.smtp.port", "<your server port>");
        properties.put("ogham.email.from.default-value", "<email address to display for the sender user>");
        // Instantiate the messaging service using default behavior and
        // provided properties
        MessagingService service = MessagingBuilder.standard()      // (1)
                .environment()
                    .properties(properties)                         // (2)
                    .and()
                .build();                                           // (3)
        // send the email using fluent API
        service.send(new Email()                                    // (4)
                        .subject("BasicSample")
                        .body().string("email content")
                        .to("[email protected]"));
    }

}

1. Use the standard builder (predefined behavior)

2. Register the custom properties

3. Create a MessagingService instance

4. Send an email with a subject and a simple body. The sender address is automatically set using ogham.email.from.default-value property

Source code of the sample.

The construction of the email is done using a fluent API in order to chain calls and to have a more readable code.

Properties are directly provided in the code. You can instead use a configuration file.

This sample shows how to send an email with a content following a template engine language.

2. Use the name attribute value in the template

3. Use the value attribute value in the template

Source code of the HTML template

Using a template is straightforward. Instead of providing a string as body (using body().string(…​)), you change to body().template(…​, …​). The template method requires two pieces of information:

• The path to the template

• The variables to evaluate in the template

The path to the template is a string that may contain a lookup prefix. The lookup prefix is used to indicate where to search the template (from file system, from classpath or anywhere else). Here we explicitly ask to load the template from classpath (using prefix classpath:). If no lookup is defined, classpath is used by default. See Resource resolution section for more information.

The variables are any object you are using in your application. No need to convert your object to a particular format. Directly use what you want.

This sample is a variant of the previous one. It allows you to directly use the HTML title as subject of your email. It may be useful to use variables in the subject too, to mutualize the code and to avoid to create a new file or to use a different evaluation syntax or context just for one line.

Source code of the text template

When you develop a Web application, you can use HTML for the content and CSS for layout and theming. HTML and CSS can use images to make a beautiful Web page. Each concern is separated in a different file. This is a good practice.

However, writing an HTML email is totally different. Indeed, email clients are not as evolved as Web browsers. Even worse, some clients disable some features on purpose (like GMail that prevents using style tag). To make an email work on several clients, you should follow these rules:

• <img> tags that use local images must be embedded

• Use XHTML instead of HTML

• Remove HTML comments (except conditional comments used to target Outlook)

• Add border=0 on all images to avoid an ugly border

• Do not write shortcut CSS values (padding: 4px 4px 4px 4px; instead of padding: 4px)

• Padding is not supported on some clients so you must use margins instead (adding a parent just for the layout)

• Background images on body should be moved on another node

• CSS3 properties are not supported

• Images must have alt attribute

• …​

There are many other rules but the developer should not be constrained and should be able to write its HTML and CSS like as usual in Web browsers. Ogham simplifies image and CSS integration and is able to partially rewrite the HTML.

2. The CSS is parsed by Ogham and applied directly on the HTML (using style attribute). The CSS may contain rules that override some rules of other CSS files (like in a browser)

3. The image is automatically embedded (the path is replaced by a Content-ID (or CID) and the image is attached to the email using ContentDisposition.INLINE with the Content-ID header). The content type is automatically determined

4. The image is converted to a base64 string. The src attribute of the image is updated using data URI scheme. The content type is automatically determined

5. Same as <3>

6. Same as <3>

7. The image is not inlined by Ogham. This can be useful to embed it manually.

Here is the list of supported transformations:

• ✓ <img> tags that use local images are embedded (using cid reference)

• ✓ <img> tags that use local images are embedded (using base64 data URI)

• ✓ Inline CSS rules using style attribute

• ✓ background images that use local images are embedded (using cid reference)

• ✓ background images that use local images are embedded (using base64 data URI)

• ❏ Use XHTML instead of HTML

• ❏ Tables used for layout explicitly set default values

• ❏ Remove HTML comments (except conditional comments used to target Outlook)

• ❏ Add border=0 on all images to avoid an ugly border

• ❏ Do not write shortcut CSS values (padding: 4px 4px 4px 4px; instead of padding: 4px)

• ❏ Padding is not supported on some clients so you must use margins instead (adding a parent just for the layout)

• ❏ Background images on body should be moved on another node

• ❏ Images must have alt attribute

Sending an email with HTML content and text content might be really important, at least for smartphones. When a smartphone receives an email, it displays the sender, the subject and also a preview of the message, using the text alternative. If the message is only HTML, the preview might be unreadable.

1. Explicitly set the textual content (used as alternative body). The alternative body is used when the email client doesn’t support HTML or as a preview of the email.

2. Explicitly set the HTML content (used as main body)

ℹ️	The call order between text() and html() doesn’t matter (unlike using .content(new MultiContent(…​))).

ℹ️	The underlying Content is a MultiContent.

Obviously, you can use templates too. Even better, the following sample shows the shorthand version that avoids specifying twice the path to the templates (a single path without extension for both HTML and text template files).

1. The body contains two parts (main body and alternative body) because there are two templates (one for HTML located at /template/thymeleaf/simple.html and one for text located at /template/thymeleaf/simple.txt). Only a single path is specified for both template files (without extension).

2. The object used for evaluation as usual when using templates (same object used for both HTML and text)

Ogham will automatically determine file extensions to append according to the kind of message you are sending. For email, Ogham will search a HTML and a text file by default:

• Using ThymeLeaf, the file extensions are .html and .txt (configurable).

• Using FreeMarker, Ogham will search files with extensions .html.ftl and .txt.ftl (configurable).

If you are using body() (or explicitly using content(new MultiTemplateContent(…​))) and you only provide one template (only HTML for example). Ogham will not fail by default (configurable). Therefore, you can start your code with only a HTML template and add the text template later when you need it. That way, your Java code doesn’t require any change.

It is possible to mix templates in the same application. Even better, you can use a template engine that is better suited for HTML like Thymeleaf and FreeMarker that is better for textual version for the same email. Just write your templates with the engine you want.

        return WithAttachmentSample.class.getResourceAsStream("/attachment/test.pdf");
    }
}

1. Attach a PDF file that exists in the classpath to the email. The name of the attachment uses the name of the file

2. Use an InputStream and name the attachment

Source code of the sample

Attaching a file to the email is quite simple. You just need to provide the path to the file. The file is loaded from classpath but could also be loaded from file system or anywhere else (see resource resolution section). In case you are using a file, the name of the attachment displayed in the email is automatically determined (test.pdf in the example).

It is often not possible to handle files directly. In that case you will use InputStream or byte[]. In that case, you need to name the attachment explicitly.

In both cases, the mimetype is automatically determined (application/pdf in this case). Mimetype is really important to ensure that the recipient(s) will be able to download or view the files correctly. It is possible to explicitly set the content type of the attachment if the automatic behavior doesn’t fit your needs.

The file content is linked to the email using ContentDisposition.ATTACHMENT.

This sample defines two properties mandatory (system ID and password) by this protocol in order to use it.

1. Configure the SMPP server host

2. Configure the SMPP server port

3. The SMPP system ID

4. The SMPP password

5. The phone number of the sender

6. Use the standard builder (predefined behavior)

7. Register the custom properties

8. Create a MessagingService instance

9. Send a SMS with a simple message. The sender phone number is automatically set using ogham.sms.from.default-value property

Source code of the sample.

The construction of the SMS is done using a fluent API in order to chain calls and to have a more readable code.

Properties are directly provided in the code. You can instead use a configuration file.

This sample shows how to send a SMS with a content following a template engine language.

ThymeLeaf template

[[${name}]] [[${value}]]

Source code of the template

Using a template is straightforward. Instead of providing a string content (using .message().string(…​)), you call .message().template(…​, …​). The template method requires two pieces of information:

• The path to the template

• The variables to evaluate in the template

The path to the template is a string with a lookup prefix. The lookup prefix is used to indicate where to search the template (from file system, from classpath or anywhere else). Here we explicitly ask to load the template from classpath (using prefix classpath:). If no lookup is defined, classpath is used by default. See Resource resolution section for more information.

The variables are any object you are using in your application. No need to convert your object to a particular format. Directly use what you want.

As you may know, SMS stands for Short Message Service. Basically, the messages are limited to a maximum of 160 characters if character encoding is using 7bits. Using a 8-bit character encoding decreases the limit to 140 characters and 70 characters for a 16-bit encoding. If needed, the library will split your messages into several parts the right way to be recomposed by clients later (according to the message encoding). Therefore, you don’t need to handle the split of messages in your code:
