Email notification using Java Mail API and Freemaker API in ADF application.

Email notification in Oracle ADF.

Sending Email using Java Email API and Freemaker template:

About  FreeMarker:  In FreeMarker you define templates, which are text files that contain the desired output, except that they contain placeholders like ${name}, and even some logic like conditionals, loops, etc. In your Java program you supply the actual values for these placeholders and the final output is generated based on this input.

How to send an email in ADF application:

1)      Create Fusion web application in Jdevloper.
2)      Add required jar as below on classpath
i)                    Freemaker.jar
ii)                   Javax.mail-1.5.0.jar
iii)                 Commons-email.jar

3)      Define Mail session on Weblogic server

4)      Add all below properties in mail session

i)                    Xxx.hostname=<your mail server>
ii)                   XXX.port=<your port number of mail server>
iii)                 XXX.username=<your email id>
iv)                 XXX.password=<your mail password>
5)      Use InitialContext to read the all properties defined in mail session

6)      Create freemaker file as save it as .ftl extension. Here in my case I am sending html content in mail so I have create file with html content and left placeholder to replace actual values at runtime. Place the same file in default domain of weblogic server.

<html>
<body>
Hi ${to},
<p style='color:red;'>${message}</p>
Regards,<br/>
${from}.
</body>
</html>

7)      How to read .ftl file in code
Freemaker api has class to load the template from server classpath and process the ftl file and replace all the placeholder in ftl file. Use below code for the same,

8)      How to send email using java mail api,

WaterMark behavior in ADF

How to create watermark/placeholder effect for input component in ADF What is watermark behavior A watermark typically appears as light gray text within an input or textarea element whenever the element is empty and does not have focus. This provides a hint to the user as to what the input or textarea element is used for, or the type of input that is required. For example, a search input space sometimes appears at the top of the page, giving the user quick access to the search functionality. Oftentimes you will see the word "Search" in light gray text in that space, and when the user clicks into the entry space, the word disappears.

WebLogic Application Deployment & Shared Library

Image
In an enterprise application deployment scenario, there are many cases where some libraries are used/referenced by multiple applications. It would indeed be a bad design to include such common libraries with every application deployed on the WebLogic server. Not only does it prevent redundancy of resources on the server, it also consumes valuable space & deployment time - especially when the libraries are huge. WebLogic server offers the shared library concept using which EARs, JARs, EJBs and WARs can be shared across applications in a WebLogic domain. Let us now see how to package and deploy a shared library in WebLogic server; Step 1: Create a folder structure as shown below Step 2: Copy all the libraries (in this case JAR files) that you would want to share across applications to the lib folder under WEB_INF Step 3: Create a file under META_INF folder by name "MANIFEST.MF" Step 4: Contents of the MANIFEST.MF file are shown below Manifest-Version: 1.
