Set server default bindings for policy sets

We can set server default bindings if we want the policy set attachments for service providers and clients that are deployed to the server to use bindings that are different than those specified for the cell. If we use multiple security domains, your default server bindings will also override the security domain default bindings.

Before we can set server default bindings for the JAX-WS application, first configure at least one general provider policy set binding or general client policy set binding. To define and manage these general bindings, use the console and select Services > Policy sets > General provider policy set bindings or Services > Policy sets > General client policy set bindings .

For transitioning users: In WAS v7 and later, the security model was 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 WAS v6.1 Feature Pack for Web Services, we 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 and later, we can configure one or more general service provider bindings and one or more general service client bindings. After we have configured general bindings, we can specify which of these bindings is the global default binding. We can also optionally specify general binding used as the default for an application server or a security domain. trns

General service provider and client bindings are not linked to a particular policy set, and they provide configuration information that we can reuse across multiple applications. We can create and manage general provider and client policy set bindings, and then select one of each binding type to use as the default for an application server. Setting the server default bindings is useful if we want the services that are deployed to a server to share binding configuration. We can also accomplish this sharing of binding configuration by assigning the binding to each application deployed to the server or by setting default bindings for a security domain and assigning the security domain to one or more servers.

We can specify default bindings for the service provider or client used at the global security (cell) level, for a security domain, for a particular server. The default bindings are used in the absence of an overriding binding specified at a lower scope. The following list is the order of precedence from lowest to highest that the application server uses to determine which default bindings to use:

  1. Server level default

  2. Security domain level default

  3. Global security (cell) default

The sample general bindings provided with the product are initially set as the global security (cell) default bindings. The default service provider binding and the default service client bindings are used when no application specific bindings or trust service bindings are assigned to a policy set attachment. For trust service attachments, the default bindings are used when no trust specific bindings are assigned. If we do not want to use the provided Provider sample as the default service provider binding, we can select an existing general provider binding or create a new general provider binding to meet the business needs. Likewise, if we do not want to use the provided Client sample as the default service client binding, we can select an existing general client binding or create a new general client binding. To specify the global security (cell) default bindings, use the console, and click Services > Policy sets > Default policy set bindings. For environments with multiple security domains, we can optionally choose the general provider and general client bindings to use as the default bindings for a domain.

In addition to choosing default bindings for the global security (cell), we can also choose the general provider and general client bindings to use as the default bindings for a server. This is only necessary to use different default bindings for a particular server than those used by the other servers in the security domain or cell.

To choose the default bindings for a server from the console, click Servers > Server Types > WebSphere application servers > server_name and then under Security, click Default policy set bindings. If we do not choose a general binding as the default for a server, the default bindings for the domain in which the server resides is used. If we do not choose a binding as the default for a domain, the default bindings for the global security (cell) are used. We must choose a default service provider and default service client bindings for the cell. The general bindings that are included with the product are initially set as the global security (cell) default bindings. We cannot delete a binding used as part of any policy set attachment or specified as the default binding for server, a domain, or the cell. To learn more about defining default bindings for a server, see the server default bindings documentation.

Mixed-version environment:

If we have an application containing one or more application specific bindings configured at the WAS v6.1 level, this application is a V6.1 application. If we have applications that are deployed to V6.1 servers within the Version 7.0 or later application server environment, or we have V6.1 applications that are deployed to V7.0 or later versions of the application server, we can specify Version 6.1 default policy set bindings for the cell. These bindings are used for both client and provider policy set attachments within V6.1 applications and attachments to service applications that are deployed to a V6.1 server. Additionally, these default bindings are used for V6.1 attachments unless they are overridden at the attachment point by an application specific binding or a V6.1 server default binding. We can upgrade V6.1 bindings to the bindings used by WebSphere Application Server V7.0 and later versions. Use the upgradeBindings command to upgrade the bindings level, if the V6.1 application is not installed on WebSphere Application Server V6.1. mixv

Depending on the assigned security role when security is enabled, you might not have access to text entry fields or buttons to create or edit configuration data. Review the administrative roles documentation to learn more about the valid roles for the application server.

  1. Open the console.

  2. To set default policy set bindings for the server, selectServers > Server Types > WebSphere application servers > server_name > Default policy set bindings.

  3. Select the server default provider binding.

    If we specify a server default provider binding, the selected binding overrides the default provider bindings specified for the cell or the security domain to which the server is deployed. The default setting is None.

    If multiple security domains are in use, the name of the security domain to which each binding is scoped displays beside the name of each available provider binding. Only the bindings that are scoped to the global security level or to the security domain to which the server is deployed are displayed.

  4. Select the server default client binding.

    If we specify a server default client binding, the selected binding overrides the default client bindings specified for the cell or the security domain to which the server is deployed. The default setting is None.

    If multiple security domains are in use, the name of the security domain to which each binding is scoped displays beside the name of each available provider binding. Only the bindings that are scoped to the global security level or to the security domain to which the server is deployed are displayed.

  5. Click Apply or OK to submit the changes.

  6. Click Save to save the changes to the master configuration.

  7. Optional. For a Version 6.1 application, we can specify server V6.1 default policy set bindings. To set these bindings, select Servers > Server Types > WebSphere application servers > server_name > Default policy set bindings > Version 6.1 default policy set bindings.

    Mixed-version environment: Select the V6.1 default bindings for this server. If the application contains one or more application specific bindings configured at the WAS V6.1 level, this application is a V6.1 application. These default bindings are used for client and provider policy set attachments for applications that are deployed to V6.1 servers, and for V6.1 applications that are deployed to V7.0 and later servers. These bindings are used for both client and provider policy set attachments within V6.1 applications and attachments to service applications that are deployed to a V6.1 server. Additionally, these default bindings are used for V6.1 attachments unless they are overridden at the attachment point by an application specific binding or a V6.1 server default binding..


Results

When you complete these steps, the server default bindings are defined and all policy set attachments that specify use of the default binding for the web service applications that are deployed to the server will use server level default bindings.


Example

Suppose we have configured an application server, server1, and we have deployed several web service applications to the server1 application server. Because these applications have similar security and quality of service requirements and you plan for them to share security configuration, to define the default bindings for policy set attachments to service providers and clients using the server1.

Suppose also to modify the provided general provider binding, Provider sample. We can copy and modify this provided sample to take advantage of existing bindings.

  1. Copy and modify the provided Provider sample and Client sample to meet the security and quality of service requirements. Include binding configuration for all policy types.

    • Click Services > Policy sets > General provider policy set bindings. Select Provider sample > copy. Name the new general provider binding, MyServiceProviderbinding , and provide a description for the new binding.

    • Click Services > Policy sets > General client policy set bindings. Select Client sample > copy. Name the new general client binding, MyServiceClientbinding, and provide a description for the new binding.

  2. Locate server1 in the Application servers collection and click the instance. From the console, select Servers > Server Types > WebSphere application servers , and click the server1 instance.

  3. Click Default policy set bindings.

  4. Select the bindings to use for the provider and client policy set attachments. In this example, select the customized general bindings, MyServiceProviderbinding and MyServiceClientbinding.

  5. Click Apply or OK to submit the changes.

  6. Click Save to save the changes to the master configuration.
Each time you attach a policy set to a service or client deployed to the server1 application server, it is initially set to use the specified bindings. .


What to do next

After setting server default bindings, we can start deploying services to the server and start attaching policy sets. Alternatively, you might already have services deployed to the server, and the server is using the global default bindings because there is no server default binding. Now that we have set server default bindings, ensure that the server default bindings are used for the service messages as specified.
