HTTP Generic Post Listener

The HTTP Generic Post Listener monitors a specified local HTTP path for POST requests and handles them according to their message type. This Listener has 8 tabs: Basic, Advanced, Transaction Logging, Inactivity, Throttling, WSDL, Authentication, and Resources.

Listener (Adapter) Configuration Drop-Down List

Basic HTTP Generic Post Listener Configuration Options

On the Basic tab, you can specify the Request Path. This is the extra information at the end of the URL that will be used to indicate that the data posted should be sent to this interface. The Timeout specifies the amount of time in milliseconds that the Listener should wait before timing out on a synchronous response. 60,000 milliseconds = 60 seconds.

• WSDL File – WSDL file that would be returned on request that ends with “?wsdl”. If you want to create new or edit existing files, you can click Edit/New to open the WSDL editor.

HTTP Generic Post Listener Basic Configuration Options

Advanced HTTP Generic Post Listener Configuration Options

The Advanced tab allows you to specify whether or not you should only run the Listener when it is triggered externally, and how many elements should be serialized.

Also, you can set:

• Allow Command-Line Invocation – if enabled, the listener can be invoked using the CLI client application
• Restart on Listening Error – if enabled, the listener will be restarted after an error occurs
• FIFO Queue Name – the FIFO options enable a “First In, First Out” queuing mechanism between Listeners and Transports. If a FIFO Queue Name is provided, it will be used as a key for a transaction queue. Transactions will be written to this queue before they reach a Transport. The transactions in this queue will be ordered according to when they were created by the Listener.
• FIFO Queue Delay – this is the interval between updates or checks against that queue. Providing a queue name guarantees that a given Transport sends transactions in the same order that the Listener created them in.
• Timeout Handling – specifies how transaction timeouts should be handled. There are three options in the drop-down menu: Send timeout message, Return original request or Throw Listener exception.
• Synchronous – specifies whether or not a response is expected
• Require SSL – if selected, plain text requests will be rejected

• HTTP Headers – allows specification of HTTP header name-value pairs to use in synchronous response

Transaction Logging HTTP Generic Post Listener Configuration Options

The Transaction Logging tab allows you to specify:

• Transaction Logging Enabled – if enabled, allows transaction events originating from this Listener to be logged by a TransactionEventListener
• Log Transaction Data – if enabled, logs transaction data body
• Log Transaction Data Base64 – if enabled, logs transaction data body as Base64
• Log Transaction Attributes – if enabled, logs transaction attributes
• Log All Attributes – if enabled, no attributes will be filtered
• Allowed Attributes –  attributes that are allowed to be logged

HTTP Generic Post Listener Transaction Logging Configuration Options

Inactivity HTTP Generic Post Listener Configuration Options

The Inactivity tab allows you to specify:

• Enable Inactivity Monitor – check this box to enable inactivity monitoring. This will throw a non-transaction exception if the specified number of transactions haven’t been processed in the specified time interval.
• Min. Transactions to Expect – the number of transactions to expect to be completed per monitoring interval
• Monitoring Interval – how often to check the specified number of transactions that have been processed
• Times to Monitor – if set, monitoring will be done during the defined times of the day. To ignore, set start and end time equally.
• Days to Exclude from Monitoring – inactivity monitoring will not occur on the days specified
• Include Errors in Transaction Count – if checked, transactions that attempted to start, but failed at the Listener stage, will also be counted

HTTP Generic Post Listener Inactivity Configuration Options

Throttling HTTP Generic Post Listener Configuration Options

The Throttling tab allows you to specify:

• Throttling Mode – the throttling mode to use for limiting the number of transactions or messages emitted by this Listener. “Timed” will limit transactions based on time intervals, while “Concurrent” will limit based on a concurrent number of transactions. “Concurrent” mode requires a Throttling Response Processor step later in your interface workflow to acknowledge completion.

HTTP Generic Post Listener Throttling Mode

• Throttling Mechanism  – the mechanism to use for throttling messages. “Blocking” prevents the Listener from continuing to process and emit messages altogether, while “queued” pushes received messages into the interface queue or a default, in-memory queue.
• Max Concurrent Messages – how many messages can be concurrently processed, either by time-based limits (allow X per second) or synchronous (allow X at any time)
• Timed Emission Interval – the interval for time-based limits (allow X per X timed emission interval)
• Synchronous Timeout Interval – the interval to wait for a synchronous response before failing

WSDL HTTP Generic Post Listener Configuration Options

On the WSDL tab you can specify:

• WSDL Content Type – specifies the content type to send with the WSDL file

HTTP Generic Post Listener WSDL Configuration Options

Authentication HTTP Generic Post Listener Configuration Options

On the Authentication tab you can specify usage of Basic Authentication:

Also, you can set:

• Authentication File – a properties file containing usernames and passwords for basic authentication
• Authentication Realm – the realm for basic authentication

HTTP Generic Post Listener Authentication Configuration Options

Resources  HTTP Generic Post Listener Configuration Options

On the Resources tab you can specify:

• Additional Resources – specifies any additional content to be served up and the URL fragment at which they are served up
