Use the -attributes parameter for the setPolicyType and
setBinding commands to specify additional configuration information
for the WSAddressing policy and policy set binding. Application and
system policy sets use the WSAddressing policy and binding.
WSAddressing is an interoperability standard for addressing Web
services and providing addressing information in messages. For more
information, see the W3C Candidate Recommendation (CR) versions of
the WS-Addressing core and SOAP specifications.
Use the following commands and parameters
in the PolicySetManagement group of the AdminTask object to customize
your policy set configuration.
- Use the attributes parameter for the getPolicyType and
getBinding commands to view the properties for your policy and binding
configuration. To get an attribute, pass the property name to the
getPolicyType or getBinding command.
- Use the attributes parameter for the setPolicyType and
setBinding commands to add, update, or remove properties from your
policy and binding configurations. To add or update an attribute,
specify the property name and value. The setPolicyType and setBinding
commands update the value if the attribute exists, or adds the attribute
and value if the attribute does not exist. To remove an attribute,
specify the value as an empty string (""). The attributes parameter
accepts a properties object.
Note: If a property name or value supplied with the attributes parameter
is not valid, then the setPolicyType and setBinding commands fail
with an exception. The property that is not valid is logged as an
error or warning in the SystemOut.log file. However, the
command exception might not contain the detailed information for the
property that caused the exception. When the setPolicyType and setBinding
commands fail, examine the SystemOut.log file for any error
and warning messages that indicate that the input for the attributes parameter
contains one or multiple properties that are not valid.
For transitioning users: In WebSphere Application
Server Version 7.0, the security model is enhanced to a domain-centric
security model instead of a server-based security model. The configuration
of the default global security (cell) level and default server level
bindings has also changed in this version of the product. In the WebSphere
Application Server Version 6.1 Feature Pack for Web Services, you
can configure one set of default bindings for the cell and optionally
configure one set of default bindings for each server. In Version
7.0, you can configure one or more general service provider bindings
and one or more general service client bindings. After you have configured
general bindings, you can specify which of these bindings is the global
default binding. You can also optionally specify general binding that
are used as the default for an application server or a security domain.
trns
To support a mixed-cell environment, WebSphere
Application Server supports Version 7.0 and Version 6.1 bindings.
General cell-level bindings are specific to Version 7.0 Application-specific
bindings remain at the version that the application requires. When
the user creates an application-specific binding, the application
server determines the required binding version to use for application.
WSAddressing policy properties
Configure
the WSAddressing policy by specifying the following properties with
the setPolicyType command:
- usingAddressing
- Specifies whether a WS-Addressing SOAP header is included on messages.
Use one of the following values:
- required
- WS-Addressing is mandatory. Servers return an error if they receive
a message that does not contain a WS-Addressing header. Clients always
include WS-Addressing headers in SOAP messages.
- optional
- WS-Addressing is not mandatory. Servers do not generate an error
if they receive a message that does not contain a WS-Addressing header.
Clients might not include WS-Addressing headers in SOAP messages,
for example, if WS-Policy is enabled and the server does not specify
that WS-Addressing is mandatory.
- wsaMode
- Specifies the messaging style that this policy set supports. Use
one of the following values:
- WSA_SYNC
- Response messages must be targeted at the WS-Addressing anonymous
URI.
- WSA_ASYNC
- Response messages must not be targeted at the WS-Addressing anonymous
URI.
- WSA_BOTH
- The targeting of response messages is not restricted.
The following example uses the setPolicyType command
to set WS-Addressing to mandatory, and the messaging style to synchronous,
for the policy set myPolicySet:.
AdminTask.setPolicyType('[-policySet "myPolicySet" -policyType WSAddressing
-attributes "[[usingaddressing required][wsaMode WSA_SYNC]]"]')
WSAddressing binding properties
Configure
the WSAddressing policy by specifying the following property with
the setBinding command:
- preventWLM
- Specifies whether to prevent workload management for references
to endpoints that were created by the application programming interface
(API) in a cluster environment. Messages that target Endpoint References
(EPRs) within a cluster environment are workload managed by default.
- Preventing workload management routes messages that target EPRs
to the node or server on which the EPR was created. You might disable
workload management if the endpoint maintains the in-memory state,
which has not been replicated across other nodes or servers within
the cluster.
For example, the following command prevents workload
management for a cell-wide general binding, from the WSAddressing
policy.
AdminTask.setBinding('[-bindingLocation "" -bindingName cellWideBinding2 -policyType WSAddressing -attributes "[preventWLM true]"]')
