XPages: Create a Database without Template

On stackoverflow.com, an interessting topic was asked about how to create a notes database programmatically without using a template. The problem is, that it will not contain a Icon document. But in this document are all database properties stored. So the question is: How can you create this document?

Jesse Gallagher came up with the idea to use the DXL import and create the Icon document this way, which works fine. But the next problem is, that there is no ACL note in the database and no default view.

That’s why I modified his idea and created a Java Utility class. This class creates a new database which includes all of the required design elements.

package ch.hasselba.core;

import lotus.domino.ACL;
import lotus.domino.Base;
import lotus.domino.Database;
import lotus.domino.DbDirectory;
import lotus.domino.DxlImporter;
import lotus.domino.Session;

            db = dbDir.createDatabase( dbPath );

            // initialize dxl importer
            importer = session.createDxlImporter();
            importer.setDesignImportOption( DxlImporter.DXLIMPORTOPTION_REPLACE_ELSE_CREATE );

            // generate DXL
            String dxl = generateDXL( dbTitle, dbPath, db.getReplicaID() );

            // import DXL
            importer.importDxl(dxl, db);

            // set ACL: Default to Manager
            acl = db.getACL();
            acl.getFirstEntry().setLevel(ACL.LEVEL_MANAGER);
            acl.save();

Here is an example XPage how to use the class:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">

    DB Path:<xp:inputText id="inputTextDBPath" value="#{viewScope.dbPath}" /><xp:br />
    DB Title:<xp:inputText id="inputText1" value="#{viewScope.dbTitle}" /><xp:br />

    <xp:button value="Create DB" id="buttonCreateDB">
        <xp:eventHandler event="onclick" submit="true" refreshMode="complete">
            <xp:this.action>
                <![CDATA[#{javascript:
                    importPackage( ch.hasselba.core );
                    var dbUtil = new ch.hasselba.core.DBUtil();
                    dbUtil.createDatabase(session, viewScope.dbTitle, viewScope.dbPath, "");
                }]]>
            </xp:this.action>
        </xp:eventHandler>
    </xp:button>

</xp:view>

You can enter the database Title and the database path. After clicking the button „Create DB“, the database is created on the server (assuming you have the right to do that).

    I was looking into this last week for XPages. you timing is impeccable. Thanks

  2. I like this for a quick bootstrapping of an empty database. I’ll likely adopt the idea for an „initialize“ method in the design portion of the OpenNTF API to populate a fresh NSF with some sensible defaults.
