Login task

The resolver toolkit contains an Ant task to login to an AstroGrid Community service. Validating an Account identifier and password and returning a SecurityToken.

Before using the login tasks, check that the Account identifier has been set to point to a valid Community and Account.

See Resolver properties

The following Ant script fragment installs the password resolver task. 

<taskdef name="login.task" classname="org.astrogrid.community.resolver.ant.CommunityPasswordResolverTask">
    <classpath refid="resolver.classpath"/>
</taskdef>

Live registry

The login.live Ant task uses a live Registry service to resolve the endpoint of a Community service, and then calls the Community service to validate the Account identifier and password.

The following command will run the login task, using a live Registry service to resolve the Community service. 

ant -f resolver.xml login.live

The following Ant script fragment calls the password resolver task, using a live Registry service to resolve the Community service. 

<login.task
    registry="${org.astrogrid.registry.url}"
    account="${org.astrogrid.community.account}"
    password="qwerty"
    />
In this mode, the task requires the following parameters :
  • registry - The endpoint URL for an AstroGrid Registry service
  • account - The IVO identifier for the Account
  • password - The Account password

If the login succeeds, then the task will print out a new security token value, returned from the Community service. The task will also store the token value in an Ant property called org.astrogrid.community.token.

Local registry

There are reported problems when using the local registry files on a Windows system.

The login.local Ant task uses local Registry files to resolve the endpoint of a Community service, and then calls the Community service to validate the Account identifier and password.

The following command will run the login task, using local Registry files to resolve the Community service. 

ant -f resolver.xml login.local

The following Ant script fragment calls the password resolver task, using local Registry properties to resolve the Community service. 

<login.task
    properties="${basedir}/config/registry.properties"
    account="${org.astrogrid.community.account}"
    password="qwerty"
    />
In this mode, the task requires the following parameters :
  • properties - The location of the local Registry properties file
  • account - The IVO identifier for the Account
  • password - The Account password

If the login succeeds, then the task will print out a new security token value, returned from the Community service. The task will also store the token value in an Ant property called org.astrogrid.community.token.
