This guide describes the GRIA Workflow Deployer Application software which works in conjunction with the GRIA Workflow Application package, and enables the automatic conversion of a user-supplied XScufl workflow into a GRIA application, which is then automatically deployed onto a GRIA Job Service. XScufl workflows may be created using Taverna or g-Eclipse.

UsernameIdentityProviderA new key-pair is generated and given a certificate signed by another Identity. This is for use in portals where users only have usernames and passwords rather then key-pairs.

UsernameIdentityProviderA new key-pair is generated and given a certificate signed by another Identity. This is for use in portals where users only have usernames and passwords rather then key-pairs.

KrbIdentityProvider An Identity is fetched from a Kerberos service. This allows users with a Kerberos or Active Directory login to get an Identity automatically.

Running a Groovy script   This is the easiest way to access the Java API. To try it out, create a script named test.groovy containing: println "Starting Groovy script!" def jobService = serviceFactory.createServiceProxy("https://host:8443/gria-basic-app-services/services/JobService?wsdl") println "Getting ID..." def id = jobService.getServiceProviderID() println "Job service identity: " + id Replace host with the address of your GRIA job service. The script is run by passing it as an argument to the normal gridcli command. For example: $ gridcli test.groovy Starting Groovy script! Getting ID... Job service identity: <subject> <subject> will appear at the identity of your job service. The configured keystore and active plugins are the same as when running the GRIA client normally.  

The bulk of the changes in 5.3 are to the client API. One exciting new > feature is built-in support for Groovy, a scripting language with a > Java-like syntax. For example, the following script will upload the > "source.jpg" file, process it with the "paint" application on > griademo1 > and then download the result:

> def GRIADEMO1_JOB_SERVICE_WSDL = > "https://griademo1.it-innovation.soton.ac.uk/gria-basic-app-services/services/JobService?wsdl > > " > def JOB_TYPE = "http://it-innovation.soton.ac.uk/grid/imagemagick/paint > " > def jobService = > serviceFactory.createServiceProxy(GRIADEMO1_JOB_SERVICE_WSDL) > def swirlJob = jobService.createJob(JOB_TYPE, "My swirl job") > swirlJob.input("inputImage").saveFromFile(new File("source.jpg")) > swirlJob.startJob(null) > while (swirlJob.stillActive()) { > println "Waiting..." > Thread.sleep(1000) > } > swirlJob.output("outputImage").read(new File("result.jpg")) > swirlJob.destroy() > > To try it, save the script as "paint.groovy" and then run the client > like this (you'll need a "source.jpg" file too, of course): > > $ gridcli ./paint.groovy > > The above script also demonstrates the new API. "serviceFactory" takes > the URL of a service's WSDL and creates a proxy for it. Notice that, > unlike the 5.2 API, 5.3 does not require you to store the proxy in a > repository.

The GRIA Workflow Application v0.2 software includes tools for deploying and running XScufl workflows as GRIA applications. XScufl workflows may be created using Taverna or g-Eclipse. A command line deployment tool generates GRIA application wrapper scripts and other requisite files from an XScufl workflow. Running the deployment tool generates a new application that can be deployed to the GRIA Job service in the usual way using the Job Service Administration web pages.

Management View The management view displays resources under the resource which they are managed by. This relationship is a parent-child relationship and this can be seen in the resources endpoint reference, right click a resource and select View EPR there is a managingresource element which tells us the endpoint of the managing resource. If a resource is unmanaged then it appears under the Management Resources node otherwise it appears under its managing resource.

Vine is a modular, extensible Java library created by the authors of GridSphere's GridPortlets Project. Vine inherits and improves upon the Resources Model of GridPortlets and generalizes it for use in many application environments. Vine can be easily packaged and deployed for use in desktop, Java Web Start, Java Servlet 2.3 and Java Portlet 1.0 applications. Using the Vine Toolkit, one composes applications as collections of resources and services for utilizing those resources. The Vine Toolkit makes it possible to organize resources into a heirarchy of domains to represent one or more virtual organizations (VOs). Vine offers security mechanisms for authenticating end-users and authorizing their use of resources within a given domain. Other core features include an extensible model for executing tasks and transparent support for persisting information about resources and tasks with in-memory or external relational databases.
