Deployment and Export of Auxiliary Web Services¶
Publishing views as widgets is a deprecated feature and it may be removed in future major versions of the Denodo Platform. The section Features Deprecated in Virtual DataPort 7.0 lists all the features that are currently deprecated.
The auxiliary web service is a special web service used by Microsoft Web Parts to obtain the data from the views or stored procedures of the Virtual DataPort server.
This Web Service can be deployed into the web container embedded in the Denodo Platform; or it can also be exported to a .war file and deployed into another J2EE Application Server.
Remember that these web services have to be deployed before using the widgets that need them.
The following figures show the syntax of the commands available to manage these web services.
DEPLOY WIDGET WEBSERVICE <name:identifier> [ LOGIN = <literal> PASSWORD = <literal> [ ENCRYPTED ] ] REDEPLOY WIDGET WEBSERVICE <name:identifier> [ LOGIN = <literal> PASSWORD = <literal> [ ENCRYPTED ] ] UNDEPLOY [IF EXISTS] WIDGET WEBSERVICE <name:identifier> EXPORT WIDGET WEBSERVICE <widget name:identifier> NAME = <output name:literal> URI = <literal> LOGIN = <literal> PASSWORD = <literal> [ ENCRYPTED ]
In this command the parameter
URI is the URL of the Virtual DataPort
server that the web service will retrieve the data from.
PASSWORD are the credentials that the
Web service of the widget will use to open a connection to the Virtual
DataPort server and execute queries.
In the statements
DEPLOY WIDGET WEBSERVICE and
REDEPLOY WIDGET WEBSERVICE, these parameters are optional. If they
are not present, the Web service is configured with the credentials of
the user that executes the
DEPLOY or the
The credentials used by the Web service are stored in its own configuration file. So if the user used by the Web service is deleted or its password changes, you have to redeploy the Web service.
The following command displays a list of the auxiliary web services deployed in the embedded container:
