Agenda

•About me

•What‘s this?

•Preamble

•Migrate database and user profiles• Legacy profile documents vs. Java Beans• Value lists made available over the whole application

•User and environment information• What can a user see and use?

•Extending Fulltext search to a facetted search• Filtering your data with meta tags

Overview

•What‘s this?• Transforming & re-using commonly used legacy patterns in

XPages• Don‘t fear Java • Avoid @Formulas in SSJS• Ideas for best practices

•What‘s it not?• An XPages Introduction• A Java beginner‘s guide• A complete application migration strategy

Preamble

•Why not to use SSJS „excessively“?• SSJS is interpreted at runtime• SSJS is compiled at runtime (every time you call it!)• Compiled SSJS is hard to debug while executed

Migrating database and user profiles

What we find in legacy apps: profile documents

Disadvantages• You cannot see them without

using tools• You can edit and create them

only programmatically• Sometimes replication issues• Unwanted Caching ;-)

Advantages• Quick access without using

lookup views• Caching

What we missed in many cases

DatabaseScript != Global Declarations

Encapsuled, no access from outside(except Database Events)

Performance-Killer

Numerous usage of those formulas slow down the app

one of many...

NSF-based, view lookup Memory-based, direct access

Ingredients

•Transformation of profile documents to „standard“ documents

1. Create a corresponding lookup view2. Optional: corresponding forms for maintenance3. Create the Java Bean classes4. Define those Bean classes in faces-config.xml

Preparation: Lookup Views

•Key for Database Profiles = dbprofile

•Key for User Profiles = Canonical Name

•Key for Value Lists = free but unique

Preparation: Java Beans

• 3 Classes:• DatabaseProfileBean• AppConfigBean• UserProfileBean

• The DatabaseProfileBean initializes the document if it doesn‘t exist

• The UserProfileBean initializes the document when the user saves it for the first time

faces-config.xml<faces-config>

<!-- Database Profile Bean --><managed-bean>

<managed-bean-name>dbprofile</managed-bean-name><managed-bean-class>com.icsug.DatabaseProfileBean</managed-bean-class><managed-bean-scope>application</managed-bean-scope>

</managed-bean><!-- User Profile Bean --><managed-bean>

<managed-bean-name>userprofile</managed-bean-name><managed-bean-class>com.icsug.UserProfileBean</managed-bean-class><managed-bean-scope>session</managed-bean-scope>

</managed-bean><!-- Application Configuration --><managed-bean>

<managed-bean-name>application</managed-bean-name><managed-bean-class>com.icsug.AppConfigBean</managed-bean-class><managed-bean-scope>application</managed-bean-scope>

</managed-bean></faces-config>

Digression: Bean Scopes & Lifecycles

•Request• Lives beginning with the request to receiving the response

•View• Within a page until changing the page, even during partial

refreshes

•Session• Per user session

•Application• During the life time of th application (e.g. until server restart or

calling an initialization method)

User and Environment Information

User and Environment Information

Name variations

Access Level

ACL Options notes.ini variables

EnvironmentBean

faces-config.xml: EnvironmentBean

19#engageug

<?xml version="1.0" encoding="UTF-8"?><faces-config>

<!-- Environment Bean --><managed-bean>

<managed-bean-name>env</managed-bean-name><managed-bean-class>com.icsug.EnvironmentBean</managed-bean-class><managed-bean-scope>view</managed-bean-scope>

</managed-bean>

</faces-config>

Example: Username Variations

<p><xp:label

value="#{javascript:env.userName}"id="label1">

</xp:label></p><p>

<xp:labelvalue="#{javascript:env.commonUserName}"id="label2">

</xp:label></p><p>

<xp:labelvalue="#{javascript:env.abbreviatedUserName}"id="label3">

</xp:label></p>

Example: ACL Options

The delete button is only visible if the user can delete documents

Even in themes!

Extending Fulltext-Search to a Facetted Search

Facetted Search

„Faceted search, also called faceted navigation or faceted browsing, is a technique for accessing information organized according to a faceted classification system, allowing users to explore a collection of information by applying multiple filters.“

http://en.wikipedia.org/wiki/Faceted_search

Facetted Search

„Well-known“ Examples

Facetted Search with Domino?

1. Fulltext Search

2. Filtering result from extra meta data

1. Meta data search with facet selection

2. Fulltext Search in results

FacettedSearchBean (Session scoped)

FacetsSearch Term

FacettedSearchBean

DocumentCollection(ArrayList<SearchResultEntry>)

Facetted Search: Outlook & Alternatives

•Using OpenNTF API‘s Graph-DB functions

•Using a 3rd party Graph-DB like Apache Solr
