Channel Reader

The Channel Reader is a connector that does nothing but wait for other channels / processes to send it messages. This can be useful if you split your message workflow into multiple channels, where one sends to another. Note that you do not need to use a Channel Reader source for the channel to be able to receive messages from other internal channels / processes. Channels using other source connector types can still receive messages from a Channel Writer or from a "router.routeMessage" call.

JavaScript Reader Return Values

If you are using the JavaScript Reader to produce messages for the channel, all you need to do is return those messages from the script. The following return values are accepted: String: Any non-empty string returned will be sent to the channel as a message. RawMessage: This is a special object that contains not only the string message data, but also information about which destinations to dispatch to, and any source map variables you wish to inject. For additional information, see The User API (Javadoc). List: If a Java List is returned, all values in the list will be sent to the channel as discrete messages. The list may contain a mix of Strings, RawMessage objects, or other objects. Empty String / null / undefined: Returning any of these (including just a "return;" statement or no return statement at all) will cause no messages to dispatch to the channel. Any Object: Any other object returned will be converted to a String via the toString() method, and that String representation wil

Database Reader

This Database Reader connects to an external database, performs a query, and reads selected rows into messages that get dispatched to the channel. This can be done using a SQL statement, or by using JavaScript mode to perform the query manually. The database connection will automatically be kept open across multiple polling windows, unless otherwise specified. This connector also supports a Post-Process section where an update statement can be performed after each row is read in, for example to set a processed flag in the source table. The values selected from the query will be automatically converted into an XML document where each column will be a separate node. That XML document is what actually gets dispatched to the channel as a message. Supported property groups: Polling Settings Source Settings Item Name Default Value Description A Driver Specifies the type of database driver to use to connect to the database. The following values are supported by default: Sun JDBC-ODBC Bridge M

File Reader

This source connector reads files from a local or remote directory on a specified interval/time schedule. Several protocols are supported, including regular local file mode, FTP, SFTP, SMB, WebDAV, and Amazon S3. Files may be read in and converted to Base64, or converted to a message string using a specific character set encoding. After reading in files, the connector has options to either delete the original files, rename them, or move them to a separate directory. Additional options (like FTPS) are available with the SSL Manager extension. Supported property groups: Polling Settings Source Settings Item Name Default Value Description A Method file The basic method used to access files to be read in. Options include File (local filesystem or NFS / mapped share), FTP, SFTP, SMB, WebDAV, or Amazon S3. Once all necessary connection/directory information has been filled in before, use the Test Read button to attempt to actually connect and test the ability to read from the directory. B Ad

JavaScript Batch Script

The JavaScript batch adapter is an option common to almost all data types. When Process Batch is enabled on the Source Settings, you can set this script from the Set Data Types Window to programmatically decide how to split the incoming data into multiple messages. Within the batch script you have access to a variable called "reader", which is a Java BufferedReader object. Use this variable to consume from the underlying character stream and return a String for each message you want to process through the channel. When you decide that no more messages should be processed, or you reach the end of the stream, return null or an empty string. Example 1 This script will simply send a message for every line in the input.return reader.readLine(); Example 2 This script will split the input into multiple messages by assuming that each new message starts with a line break and the characters "MSH". Note that this is already a feature supported by the , but is shown here to illustrate how the batc
