How to create a SERVICE on GENIUS PORTAL




<ef:service id="edit-file"> <ef:name>View/Edit a File</ef:name> <ef:info>With this service you may edit

a file in your home directory. </ef:info> <ef:option id="filetoedit"

label="Select File to View/Edit" type="rfb" base="${HOME}" target="@genius"/>

<ef:action id="view" label="View"> $EF_ROOT/plugins/genius/bin/geniusgrid.sh view-file <ef:result type="text/html"/> </ef:action> <ef:action id="edit" label="Edit"> $EF_ROOT/plugins/genius/bin/geniusgrid.sh edit-file <ef:result type="text/xml"/> </ef:action> </ef:service>



Services Creations StepsThe steps you have to follow in order to make your new service accessible

to the users, are:

• Choose the Service Definition File that will include the new service;

• Write the <ef:service> tag and give it an unique identifier. This identifier must be located in the id attribute of the tag;

• Add a <ef:name> tag which will be used as the readable text for the hyper-link in the page containing the services. Clicking on the hyper-link will execute the service;

• Add an <ef:action> tag;

• As a text node of the <ef:action> tag, add the command that must be executed. for example, ${EF_ROOT}/plugins/ef/bin/ef.test. Note the use of the ${EF_ROOT} syntax: this makes your Genius services independent from the Genius installation directory;

• As a child node of the <ef:action> tag, add the <ef:result> tag. The attribute type of <ef:result> suggests to the Genius Server what kind of output it should expect. (XML, HTML or Simple Text);

• Finally, close the <ef:action> and the <ef:service> tags.



<ef:agent> in Detail.. • Sub tags of <ef:agent>

– [optional] <ef:name> – title of the web page– [optional] <ef:info> – welcome message of the opening

page– [optional] <ef:location> – location of Remote Agent(s)

[required] host – hostname/IP address of EF Agent host [required] port – TCP port used by EF Agent

– [optional] <ef:include> – external XML libraries of functions [required] xml – path to an SDF which contains XML libraries

– [optional] <ef:spooler> – definition of default data [required] server – server-side absolute path of spoolers [optional] agent – agent-side absolute path of spoolers [optional] ttl – defines how long the spoolers will be

accessibleformat: [DD]d[HH]h[MM]m[SS]s, 0(remove immediately), -

1(not create)

– [required] <ef:folder id="root"> – first folder of the service tree.
