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 is common to all tasks. It contains a text area (Task comments)that lets
you write comments about the task. These comments are saved when the dialog is closed with
the OKbutton, and are displayed in the Task Comments Pane.
Check the option Use as step description to display the text next to the icon of the plugin in
the Process area.
SOAP Client plugin
SOAP Client plugin tasks can be used as input, output and action tasks, although their basic
function is to generate output. SOAP (Simple Object Access Protocol) is a light protocol that
defines a standard XML format used to communicate among systems across different
architectures, languages, and operating systems.
A SOAP request is an XML-based Remote Procedure Call (RPC) sent using the HTTP
transport protocol. The payload of the SOAP packet is an XML document that specifies the call
being made and the parameters being passed.
Web services, a SOAP class of applications, expose their services via the Internet in a manner
that lets other applications access them, as well as use and combine them as required.
In order to access and successfully use Web services, client applications must know how to get
them, what operations they support, what parameters they expect, as well as what they return.
SOAP servers make this information available via WSDL (Web Service Description Language)
files.
To configure a given SOAP Client plugin task in the PReS Workflow Configuration program,
you must first get its WSDL file (note that you cannot download the WSDL file over an HTTPS
connection, so you should use an HTTP connection to get the file and then switch back to a
secure connection). This lets you know which services the SOAP server provides, as well as
each service’s methods and name spaces.
