Common Errors
Though some error messages are specific to a task in particular, others may apply to any and all tasks
because they are related more to the system than to PReS itself. Some examples would be W3813, W3830,
W3991, W4005. These correspond to issues such as not having any space to write files, permission errors
on folders or files, etc.
Comments Tab
The Comments tab, added in PReS Suite 7.5, is common to all tasks. It contains a single text area (Task
comments)that lets you write comments about the task. These comments are saved when the dialog is
closed with the OKbutton, and are displayed in The Task Comments Pane.
HTTP Client Input
HTTP Client Input tasks use the HTTP protocol to issue HTTP GET commands (queries) to HTTP servers.
Replies received from the HTTP servers are used as jobfiles and are thus passed on to following tasks.
Input
This initial input task retrieves a single file as specified in the URLoption. This file may be of any format,
even formats that are not readable by PReS Workflow.
Processing
No processing is done by this task. The file retrieved is not changed in any way.
Output
HTTPClient Input will output a single file which was retrieved from the web. Metadata is not generated by
this task.
HTTP Client Input task properties are as follows:
General tab
l URL: Enter the URL of the HTTP server from which the file must be downloaded. Since this is a
variable property box, variables may be used, as well as the Get Data and Select Data commands.
Note that when PReS Workflow connects to a secure page, an SSL (Secure Socket Layer) connection
is automatically used.
