Adaptor Pattern

• Why we need ?
• Two parties , incompatible with each other
• Since they are incompatible --> Need Adaptor --> CONVERTS One to Another

• Flow
• The client makes a request to the adapter by calling a method on it using the target interface.
• The adapter translates that request on the adaptee using the adaptee interface.
• Client receive the results of the call and is unaware of adapter’s presence.

Envronment Set up

• Need two Vms { Windows,Dev}{Linux,Docker}
• Set up ActiveMQ -  windows vm
• https://activemq.apache.org/components/classic/download/
• Code base
• Perforce: //Source_Code/ELP-Customisation/Elnino/Adaptors/
• Jboss : deploy mock service
• https://wildfly.org/downloads/
• Deployment folder : %JBoss_Install_Location%\standalone\deployments
• Start Jboss : %JBoss_Install_Location%\bin\standalone.bat 
• Gradle

ELP Adaptors - Framework

• Apache camel Route
• simplest form, an Adapter will receive a message at an input endpoint and send it to an output endpoint.

• Adapter will be required to do some processing 
• on the input message before sending to the output endpoint. 
• implement a single instance of the AdapterRequestProcessor interface

• send a message to a synchronous output endpoint, and process a response from that endpoint, before sending the response to another output endpoint. 
• AdapterResponseProcessor 

What else can be done

• Adaptor Can
• Decrypt incoming messages
• Encrypt Outgoing messages
• Aggregate result to a single route

Solve certificate Issue

1. Copy certificate to local machine
2. Import into your JVM trust store using administrator command prompt

• Import

"C:\Program Files\Java\jdk1.8.0_201\bin\keytool.exe" -import -file "%Path_To_Cert%" -alias "localhost" -keystore "C:\Program Files\Java\jdk1.8.0_201\jre\lib\security\cacerts“

• Delete

"C:\Program Files\Java\jdk1.8.0_201\bin\keytool.exe" -delete -alias "localhost" -keystore "C:\Program Files\Java\jdk1.8.0_201\jre\lib\security\cacerts"
