An administrator can configure a network folder, known as a watched folder, so that when a user places a file (such as a PDF file) in the watched folder, a configured service operation is invoked and manipulates the file. After the service performs the specified operation, it saves the modified file in a specified output folder.
After configuring the Watched Folder service, you add a Watched Folder endpoint for the target service. When adding the endpoint, you set values, such as the service name and operation name to invoke when files or folders are placed in the input folder of the configured Watched Folder service. For details on configuring the Watched Folder service, see Watched Folder service settings.
In a clustered environment, the folder that is used as a watched folder must be accessible, writable, and shared on the file system or network. In this scenario, each application server instance of the cluster must have access to the same shared folder.
Watched folders can be chained together so that a result document of one watched folder is the input document of the next watched folder. Each watched folder can invoke a different service. By configuring watched folders in this manner, multiple services can be invoked. For example, one watched folder could convert PDF files to Adobe PostScript and a second watched folder could convert the PostScript files to PDF/A format. To do this, simply set the result folder of the watched folder defined by your first endpoint to point to the input folder of the watched folder defined by your second endpoint.
Output from the first conversion would go to \path\result. Input for the second conversion would be \path\result, and output from the second conversion would go to \path\result\result (or the directory you define in the Result Folder box for the second conversion).
When the input is a folder and the output consists of multiple files, AEM forms creates an output folder with the same name as the input folder and copies the output files into that folder. When the output consists of a document map containing a key-value pair, such as the output from an Output process, the key is used as the output file name.
The output file names that result from an endpoint process cannot contain characters other than letters, numbers, and a period (.) before the file extension. AEM forms converts other characters to their hexadecimal values.
In addition to the services listed above, Watched Folder also depends on other services, including the Scheduler service for scheduling the jobs and the Job Manager service to support asynchronous invocation of target services.
The Watched Folder service handles the creation, update, and deletion of the endpoints. After the administrator creates the endpoints, they are scheduled to be triggered by the Scheduler service based on the specified repeat interval or cron expression.
The provider.file_write_results_service handles the response or failure of the target service invocation. When successful, the output is saved to the result folder based on the endpoint configuration. The provider.file_write_results_service also preserves the source if the endpoint is configured to preserve the results upon successful completion.
When the invocation of the target service results in a failure, the provider.file_write_results_service logs the reason for the failure in a failure.log file and places that file in the failure folder. The failure folder is created based on the configuration parameters specified for the endpoint. When the administrator sets the Preserve On Failure option for the endpoint configuration, the provider.file_write_results_service also copies the source files into the failure folder. For information about recovering files from the failure folder, see Failure points and recovery.
Path: (Mandatory) Specifies the watched folder location. In a clustered environment, this setting must point to a shared network folder that is accessible from every computer in the cluster.
Asynchronous: Identifies the invocation type as asynchronous or synchronous. The default value is asynchronous. Asynchronous is recommended for long-lived processes, while synchronous is recommended for transient or short-lived processes.
Repeat Interval: The interval in seconds for scanning the watched folder for input. Unless the Throttle setting is enabled, Repeat Interval should be longer than the time to process an average job; otherwise, the system may become overloaded. The default value is 5. See the description for Batch Size for additional information.
Throttle: When this option is selected, it limits the number of watched folder jobs that AEM forms processes at any given time. The maximum number of jobs is determined by the Batch Size value. (See About throttling.)
Batch Size: The number of files or folders to be picked up per scan. Use to prevent an overload on the system; scanning too many files at one time can cause a crash. The default value is 2.
The Repeat Interval and Batch Size settings determine how many files Watched Folder picks up in every scan. Watched Folder uses a Quartz thread pool to scan the input folder. The thread pool is shared with other services. If the scan interval is small, the threads will scan the input folder often. If files are dropped frequently into the watched folder, then you should keep the scan interval small. If files are dropped infrequently, use a larger scan interval so that the other services can use the threads.
If there is a large volume of files being dropped, make the batch size large. For example, if the service invoked by the watched folder endpoint can process 700 files per minute, and users drop files into the input folder at the same rate, then setting the Batch Size to 350 and the Repeat Interval to 30 seconds will help Watched Folder performance without incurring the cost of scanning the watched folder too often.
When files are dropped into the watched folder, it lists the files in the input, which can reduce performance if scanning is happening every second. Increasing the scan interval can improve performance. If the volume of files being dropped is small, adjust the Batch Size and Repeat Interval accordingly. For example, if 10 files are dropped every second, try setting the Repeat Interval to 1 second and the Batch Size to 10.
Wait Time: The time, in milliseconds, to wait before you scan a folder or file after it is created. For example, if the wait time is 3,600,000 milliseconds (one hour) and the file was created one minute ago, this file will be picked up after 59 or more minutes have passed. The default value is 0.
This setting is useful to ensure that a file or folder is completely copied to the input folder. For example, if you have a large file to process and the file takes ten minutes to download, set the wait time to 10*60 *1000 milliseconds. This prevents the watched folder from scanning the file if it is not ten minutes old.
Exclude File Pattern: A semi-colon ; delimited list of patterns that a watched folder uses to determine which files and folders to scan and pick up. Any file or folder with this pattern will not be scanned for processing.
This setting is useful when the input is a folder with multiple files. The contents of the folder can be copied into a folder with a name that will be picked up by the watched folder. This prevents the watched folder from picking up a folder for processing before the folder is completely copied into the input folder.
Include File Pattern: (Mandatory) A semi-colon ; delimited list of patterns that the watched folder uses to determine which folders and files to scan and pick up. For example, if the Include File Pattern is input*, all files and folders that match input* are picked up. This includes files and folders named input1, input2, and so on.
Result Folder: The folder where the saved results are stored. If the results do not appear in this folder, check the failure folder. Read-only files are not processed and will be saved in the failure folder. This value can be an absolute or relative path with the following file patterns:
If the path is not absolute but relative, the folder will be created inside the watched folder. The default value is result/%Y/%M/%D/, which is the Result folder inside the watched folder. For more information about file patterns, see About file patterns.
Preserve Folder: The location where files are stored after successful scanning and pick-up. The path can be an absolute, a relative, or a null directory path. You can use file patterns, as described for Result Folder. The default value is preserve/%Y/%M/%D/.
Overwrite Duplicate Filenames: When set to True, files in the results folder and preserve folder are overwritten. When set to False, files and folders with a numeric index suffix are used for the name. The default value is False.
Purge Duration: (Mandatory) Files and folders in the result folder are purged when they are older than this value. This value is measured in days. This setting is useful in ensuring that the result folder does not become full.
Input Parameter Mappings: Used to configure the input required to process the service and operation. The settings available depend on which service is using the watched folder endpoint. Here are the two types of inputs:
Literal: The watched folder uses the value entered in the field as it is displayed. All basic Java types are supported. For example, if an API uses input such as String, long, int, and Boolean, the string is converted to the proper type and the service is invoked.
Variable: The value entered is a file pattern that the watched folder uses to pick the input. For example, if there is the encrypt password service, where the input document must be a PDF file, the user can use *.pdf as the file pattern. The watched folder will pick up all files in the watched folder that match this pattern and invoke the service for each file. When a variable is used, all input files are converted to documents. Only APIs that use Document as the input type are supported.
