| + | This page refers to Home Library 1.0 API that is not supported anymore. |
| − | The Home Library manage and persist the users homes.
| + | |
| | | | |
| − | ==Architecture==
| + | Please, use the following redirect for Home Library 2.0 API: |
| − | The ''user's homes'' are organized in scopes.
| + | |
| | | | |
| − | The users and the homes for a specific scope are managed by the '''HomeManager'''.
| + | #REDIRECT [[Home Library 2.0 API Framework Specification]] |
| − | | + | |
| − | Each user home ('''Home''') have a workspace area ('''WorkspaceArea''') and a data area ('''DataArea''').
| + | |

| − | ===Workspace Area model===
| + | |
| − | The figure 2 illustrate the Workspace Area model.
| + | |
| − | | + | |
| − | [[Image:homelibrary-workspacearea-model.png|frame|center|Figure 2. Workspace Area model]]
| + | |
| − | | + | |
| − | Each element contained in a workspace area is a '''WorkspaceAreaItem'''.
| + | |
| − | | + | |
| − | There are two kind of item container: the '''Workspace''' and the '''Basket''', both can be referred as '''WorkspaceFolder'''.
| + | |
| − | | + | |
| − | A workspace can contain one or more workspacefolder.
| + | |
| − | | + | |
| − | A basket can contain only '''BasketItems'''.
| + | |
| − | | + | |
| − | In each workspace area there is a '''Default Basket''', a special basket that can't be deleted or moved.
| + | |
| − | | + | |
| − | The basket items are the effective user objects.
| + | |
| − | | + | |
| − | The figure 3 illustrate the BasketItem model.

| − | ==Setup the Home Library==
| + | |
| − | ===Installation===
| + | |
| − | To use the HomeLibrary you first need the HomeLibrary downloadable from:
| + | |
| − | * [https://grids16.eng.it/BuildReport/list/Recent_Builds] last night build
| + | |
| − | * [http://software.d4science.research-infrastructures.eu/] gcube distribution site
| + | |
| − | | + | |
| − | Add the org.gcube.portlets.user.homelibrary.jar file to your gcore installation (''$GLOBUS_PATH/lib'' folder).
| + | |
| − | | + | |
| − | ====Dependecies====
| + | |
| − | The home library require some library to be used:
| + | |
| − | *xstream-1.3.1.jar XML serialization (XStream)
| + | |
| − | *xpp3_min-1.1.4c.jar XML serialization (XStream)
| + | |
| − | *bcprov-ext-jdk15-141.jar manipulate pdf
| + | |
| − | *iText-2.1.4.jar manipulate pdf
| + | |
| − | *ij140g.jar manipulate images
| + | |
| − | | + | |
| − | Add those libraries to your gcore installation (''$GLOBUS_PATH/lib'' folder).
| + | |
| − | | + | |
| − | ===Configuration===
| + | |
| − | To be used the Home Library need a folder where create a persistence dir (''For test use is not necessary to configure it'').
| + | |
| − | | + | |
| − | There are different way to specify the base dir where create the persistence dir:
| + | |
| − | # set the HOME_LIBRARY_PERSISTENCE_DIR environment variable
| + | |
| − | # set the system property catalina.base (generically set by tomcat), then the "catalina.base/webapps/usersArea" is used a base dir
| + | |
| − | # If none of preceding properties is specified the system tmp directory is used a base dir. ''Make attention, sometime the tmp folder is delete at system reboot, use it only for test''.
| + | |
| − | | + | |
| − | Inside the base dir a home_library_persitence dir is created and used.
| + | |
| − | | + | |
| − | ==Using the Home Library==
| + | |
| − | | + | |
| − | ===Retrieve an User WorkspaceArea step by step===
| + | |
| − | Firs of all is necessary to retrieve an instance of '''HomeManagerFactory''', this can be done using the static methods from '''HomeLibrary''' class.
| + | |
| − | | + | |
| − | This example create an HomeLibrary instance that use a tmp directory (''home_library_persistence'') into the tmp system dir to save the library state. This directory is never deleted by the library. To reset the library state you can delete it.
| + | |
| − | <source lang="java5">
| + | |
| − | HomeManagerFactory factory = HomeLibrary.getHomeManagerFactory();
| + | |
| − | </source>
| + | |
| − | | + | |
| − | Obtained the factory you can retrieve the HomeManager for a specified scope:
| + | |
| − | <source lang="java5">
| + | |
| − | HomeManager manager = factory.getHomeManager(scope);
| + | |
| − | </source>
| + | |
| − | Where ''scope'' can be a GCUBEScope object or a GCUBEScope expression (for test you can use any expression).
| + | |
| − | | + | |
| − | Then we retrieve the User home:
| + | |
| − | <source lang="java5">
| + | |
| − | User user = manager.createUser(portalLogin);
| + | |
| − | Home home = manager.getHome(user);
| + | |
| − | </source>
| + | |
| − | Where ''portalLogin'' is the user username used to login into the portal (for test you can use any username).
| + | |
| − | | + | |
| − | Finally we can get the WorkspaceArea with his root:
| + | |
| − | <source lang="java5">
| + | |
| − | WorkspaceArea wa = home.getWorkspaceArea();
| + | |
| − | Workspace root = wa.getRoot();
| + | |
| − | </source>
| + | |
| − | | + | |
| − | | + | |
| − | ===How to retrieve an User WorkspaceArea from a servlet===
| + | |
| − | To retrieve a WorkspaceArea for a User you can use the getWorkspaceArea static method from HomeLibrary class. This method required only the current D4ScienceSession.
| + | |
| − | | + | |
| − | <source lang="java5">
| + | |
| − | WorkspaceArea wa = HomeLibrary.getUserWorkspaceArea(session);
| + | |
| − | </source>
| + | |
| − | | + | |
| − | ===Show the WorkspaceArea content===
| + | |
| − | The utility class '''WorkspaceTreeVisitor''' offer two method for workspace area visit:
| + | |
| − | * visitSimple which show only workspace area item name's
| + | |
| − | * visitVerbose which show rich information about each item
| + | |
| − | | + | |
| − | There is an example (''root'' is the user root workspace):
| + | |
| − | <source lang="java5">
| + | |
| − | WorkspaceTreeVisitor wtv = new WorkspaceTreeVisitor();
| + | |
| − | wtv.visitSimple(root);
| + | |
| − | wtv.visitVerbose(root);
| + | |
| − | </source>
| + | |
| − | | + | |
| − | There is a simple output:
| + | |
| − | <source lang="text">
| + | |
| − | /[root]
| + | |
| − | /{My Default Basket}
| + | |
| − | /{My first basket}
| + | |
| − | /MyUrl
| + | |
| − | </source>
| + | |
| − | | + | |
| − | There is the verbose output;
| + | |
| − | <source lang="text">

| − | ===Examples===
| + | |
| − | There are some example of HomeLibrary use.
| + | |
| − | ====Create an ExternalUrl into a basket====
| + | |
| − | After had retrieved the user workspace root:
| + | |
| − | <source lang="java5">
| + | |
| − | Basket basket = root.createBasket("My first basket", "This is my first basket created with the HomeLibrary");
| + | |
| − | | + | |
| − | basket.createExternalUrlItem("MyUrl", "This is my url", "https://technical.wiki.d4science.research-infrastructures.eu/documentation/index.php/Home_Library");
| + | |
| − |
| + | |
| − | WorkspaceTreeVisitor wtv = new WorkspaceTreeVisitor();
| + | |
| − |
| + | |
| − | wtv.visitVerbose(root);
| + | |
| − | </source>
| + | |
| − | | + | |
| − | ====Create an ExternalFile into a basket====
| + | |
| − | After had retrieved the user workspace root:
| + | |
| − | <source lang="java5">
| + | |
| − | Basket basket = root.createBasket("My first basket", "This is my first basket created with the HomeLibrary");
| + | |
| − | | + | |
| − | File myFile = new File("build.xml");
| + | |
| − | InputStream fileData = new FileInputStream(myFile);
| + | |
| − |
| + | |
| − | basket.createExternalFileItem("My External File", "This is an external file", "text/xml", fileData);
| + | |
| − |
| + | |
| − | WorkspaceTreeVisitor wtv = new WorkspaceTreeVisitor();
| + | |
| − |
| + | |
| − | wtv.visitVerbose(root);
| + | |
| − | </source>
| + | |
| − | | + | |
| − | ====Turn off the HomeLibrary logging====
| + | |
| − | | + | |
| − | The HomeLibrary logging system is under refactory, currently the tmp solution is to use:
| + | |
| − | <source lang="java5">
| + | |
| − | LoggingUtil.reconfigureLogging();
| + | |
| − | </source>
| + | |
| − | | + | |
| − | This command remove all appenders from the root logger and add it a console appender with ERROR threshold.
