There are always needs to build E-commerce sites with Credit Card transactions securely and seamlessly. In Singapore market, eNETs is the most well-known company providing payment gateway services. Up to now, eNETS only provide API for .NET and Java platform. In this post, I will show you my solution to integrate eNETS and Ruby on Rails via Java.
Steps:
1. Build JAR file to submit payment info to eNETS, i named it enets.jar. This jar file will return output from eNETS to console in text format. I attached sample program built with NetBean, you can download it here: eNETS. After downloading, you just copy that folder to your NetBean projects folder as shown in below image.

2. Follow eNETS guideline, change setting for java security as well as generate merchant.priv.pgp.asc, merchant.pub.pgp.asc.
3. Change config: log4j.properties, NETSConfig.xml
4. Build enets.jar file from source files in NetBean. Right click on project root, Clean and Build.
5. Generate command to execute enets.jar, something like this:
“java -jar #{RAILS_ROOT}/vendor/extensions/payment_gateway/lib/enets/eNETS.jar #{mid} #{tid} #{paymentMode} #{amt} #{currency} #{merRef} #{submitMode} #{merCertId} #{pan} #{expiry} #{stan} #{paymentType} #{successURL} #{successURLParams} #{failureURL} #{failureURLParams} #{notify_url} #{notify_url_params} #{name} #{cvv} #{post_url} #{post_url_params} #{cancel_url} #{cancel_url_params} #{bill_first_name} #{bill_last_name} #{bill_initial} #{bill_addr1} #{bill_addr2} #{bill_coy_name} #{bill_city} #{bill_state} #{bill_zip_code} #{bill_country} #{bill_mobile_num} #{bill_phone_num} #{bill_fax_num} #{bill_email} #{ship_first_name} #{ship_last_name} #{ship_initial} #{ship_addr1} #{ship_addr2} #{ship_coy_name} #{ship_city} #{ship_state} #{ship_zip_code} #{ship_country} #{ship_mobile_num} #{ship_phone_num} #{ship_fax_num} #{ship_email} #{shopper_ip_addr} #{product_format} #{product_details} #{gw_url}”6. Run enets.jar from ruby console with output = %x[#{command}]. %x[] command will store output to output variable for later processing. It is not the same as system() or exec() ruby command.

7. Parse results returned from enets.jar and continue with your business logic in your ruby/rails application. For rails project, i recommend you to use Active-Merchant and modify Bogus payment gateway so that you will follow format of ActiveMerchant framework. You will be supprised because the effort required is very little.
