= Using Vaadin In IBM Domino
Vaadin can be used as a UI technology in Domino. This page will contain
the instruction how to setup the development environment and to get
started with your first Vaadin app in Domino.
The steps for setting up XPages SDK are:
1. Download the
http://www.openntf.org/main.nsf/project.xsp?r=project/XPages%20SDK%20for%20Eclipse%20RCP/releases/0C60A1BFF5F40FD586257D8D005AA593[XPages
SDK for Luna and above from OpenNTF]
2. In Eclipse, from the Help menu select *Install New Software….*
3. Select *Add…*, then choose *Archive…* and navigate to the zip file
downloaded. +

4. You will need to deselect *Group items by category*. Two features
will show. The first includes sources, so select the second and click
*Next*. +
image:https://lh6.googleusercontent.com/PcTpwSQ-XpG-6c51FQ0W2upuK7XTNmawdi8vVgMb31pCBUg8Lt1oInKXT7r7o21Qjj_KJtie3yLxtPvGtCnltuNwGtj42ChuMEJBkqys8nt3KCmilFydpm6iFrme6Ro-FL4uZtUjkA[Select features]
5. Accept the terms and finish the dialog. You will be prompted to
restart Eclipse to complete the install.
6. Select *Window* > *Preferences* (on Mac the location is *Eclipse* >
*Preferences*). In the XPages SDK category tick *Automatically create
JRE* and point to your local Notes and Domino installs. Then click
*Apply*. +

7. In the *Java* > *Installed JREs* category you should now have two
additional options, “XPages Domino JRE” and “XPages Notes JRE”. Under
*Plug-in Development* > *Target Platform* click *Add…*. Select the
*Domino Install Target* template and complete. +

8. Apply this as the target platform. +

If you do not have a Domino server installed, there is an alternative
approach. However, to test your OSGi plugin, you will need to create a
Feature project, add the Plugin to that feature, then create an Update
Site Project, add the feature to the update site, build and export. Then
you will need to import that into an Update Site database on your
server. This is the same process for creating and testing any other OSGi
plugin on the server, such as XPages Extension Library.
1. Download the
http://www.openntf.org/main.nsf/project.xsp?r=project/XPages%20SDK%20for%20Eclipse%20RCP/releases/0C60A1BFF5F40FD586257D8D005AA593[IBM
Domino Update Site for Build Management from OpenNTF]. This is basically
a zip file that contains features and plugins required for Maven and
Tycho development in Eclipse, but also has all the dependencies required
for Eclipse.
2. In Eclipse, go to *Window* > *Preferences* (on Mac the location is
*Eclipse* > *Preferences*). Then go to *Plug-in Development* > *Target
Platform*.
3. Edit the existing target platform configuration and in the dialog,
click *Add…*, then *Directory*, then Next. Browse to and select the
folder where you extracted the Update Site.> +

4. The current release of Domino, 9.0.1, only supports Java 1.6. The
next release, probably called Domino 9.0.2 and expected to ship first
half 2016, is expected to include Java 1.8. But in the meantime, it’s
best to set the JRE accordingly. In the preferences, go to *Java* >
*Installed JREs* category.
5. *Add…*, *Standard VM*, then *Next* +

6. Click *Directory* and browse to your IBM Notes install’s “jvm”
library. Give it an appropriate name and click *Finish*. Alternatively,
if you don’t have IBM Notes installed on the development environment,
download Java SE 6 SDK from Oracle. +

[[setting-up-vaadin]]
Setting up Vaadin
^^^^^^^^^^^^^^^^^
Eclipse has a set of Vaadin plugins that can easily be installed to set
up your environment.
1. *Select *Help* > *Eclipse Marketplace…*.*
2. Search for "Vaadin" amd install the**Vaadin Plugin for Eclipse** +
image:https://lh4.googleusercontent.com/SpgGN3m6aFksfRJG47RVBg4qi5D7r9dhfaIUwHkm3A8TLfkF6M2farq2ZZf-zvjZakrNl1wALHHqGtiP6GNoVyIFHJs9Dpr9Tt3yqtWS6TwFMN1qsJ47o3T4UqU-G1SW0KCIbQGBnA[Select Vaadin plugin]
3. The options to install will include the *Vaadin Designer*, so leave
all selected, confirm and accept the license. You will be prompted to
restart Eclipse to complete the install.
[[hello-world-example]]
Hello World Example
^^^^^^^^^^^^^^^^^^^
Now the development environment is set up, it’s time to create a Hello
World application. But this one will not just print “Hello World” to the
browser, instead it will add in the other key aspect, integrating with
Domino. Maven is a useful tool for loading dependencies automatically,
but will require the
http://www.openntf.org/main.nsf/project.xsp?r=project/IBM%20Domino%20Update%20Site%20for%20Build%20Management[IBM
Domino Update Site for Build Management] mentioned earlier. So at this
point the approach will just create a simple non-Mavenized plugin.
1. In Eclipse, select *File* > *New* > *Plug-in Project* and give it a
name. As an OSGi plugin, tell it to run with the OSGi framework
“Equinox”.
image:img/domino1.png[1]
2. Until the next release of Domino is out, the execution environment
needs to be changed to Java 1.6. Then finish – the Eclipse perspective
used for development is not significant at this stage.
image:img/domino2.png[2]
3. The MANIFEST.MF will be opened and some additional configuration is
required. The plugin should be set as a singleton on the Overview tab.
image:img/domino3.png[3]
4. On the Dependencies tab some plugins and packages need loading for
OSGi and Domino, as below.
image:img/domino4.png[4]
5. Back on the Overview tab, click the Extension Points link and
confirm you want to display the Extension and Extension Point pages.
image:img/domino4.png[5]
6. On the Extensions tab, click *Add…* and choose
`com.ibm.pvc.webcontainer.application`.
image:img/domino6.png[6]
7. Set the contextRoot to “/helloVaadin”.
image:img/domino7.png[7]
8. Right-click on *com.ibm.pvc.webcontainer.application* and select
*New* > *contentLocation*. Set it to “WebContent”. These two steps can
be done by manually typing the relevant XML onto the plugin.xml tab and
I would recommend you loop at what the resulting XML is.
image:img/domino8.png[8]
9. Next download the Vaadin jar files that will be needed from the
https://vaadin.com/download#direct-download[Vaadin website]. The
README.txt file outlines the steps required to add it to the project,
but are repeated below.
10. Right-click the project and select *New* > *Folder* and call it
WebContent/WEB-INF/lib.
image:img/domino9.png[9]
11. Copy all jars to WebContent/WEB-INF/lib. Copy all jars in the lib
folder to WebContent/WEB-INF/lib.
12. In the MANIFEST.MF, on the *Runtime* tab in the *Classpath* section,
click *Add…* and add all the jar files added to WebContent/WEB-INF/lib.
You must select the jars, not the folder. Then remember to move the “.”
entry to the top of the list.
image:img/domino10.png[10]
13. Right-click the WebContent/WEB-INF folder and select *New* > *File*.
Call it web.xml.
14. Paste in the code below:
+
[source,xml]
....
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name>HelloVaadin</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<context-param>
<description>Vaadin production mode</description>
<param-name>productionMode</param-name>
<param-value>false</param-value>
</context-param>
<servlet>
<servlet-name>HelloVaadinServlet</servlet-name>
<servlet-class>com.vaadin.server.VaadinServlet</servlet-class>
<init-param>
<param-name>UI</param-name>
<param-value>com.paulwithers.hellovaadin.HelloVaadinUI</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>HelloVaadinServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
....
+
This first block gives a list of default URL extensions accepted for
mapping and tells the application to run in development mode. The
<servlet> block gives the servlet name and points to a class we will
create later which will initialise the NotesThread required for talking
to Domino. The initParam points to a class we will create later that
will be the entry point into the application.
15. Right-click com.paulwithers.hellovaadin and select *New* > *Vaadin
Design*. You will need an evaluation or full license for Vaadin
Designer. To get the trial license, log into the vaadin.com website and
go to https://vaadin.com/designer#license-modal[https://vaadin.com/designer#license-modal.]
16. Call the design page “WelcomeDesign” and use the *Vertical Layout*
template. Finish and confirm to switch to the Vaadin perspective.
17. Drag and drop a new Label onto the page (components are displayed
alphabetically). In the Properties view set the name to “label1”. Click
the ellipsis button next to *StyleName*. Select “LABEL_H2” and click
*Add ->*, then OK. Change *ComponentAlignment* to “TOP_CENTER”. Save and
close.
18. Switch back to the Plug-in Development perspective. This is better
suited to plugin development. Note the “WelcomeDesign.html” and
“WelcomeDesign.java” files. Review WelcomeDesign.java.
19. Right-click on com.paulwithers.hellovaadin and select *New* >
*Class*. Call it WelcomeView and set the superclass as WelcomeDesign.
image:img/domino12.png[12]
20. Add the following code to the class to extend the auto-generated class and to compute the value of label1.
+
[source,java]
....
import com.ibm.domino.osgi.core.context.ContextInfo;
public class WelcomeView extends WelcomeDesign {
private static final long serialVersionUID = 1L;
public WelcomeView() {
super();
try {
label1.setValue("Welcome " +
ContextInfo.getUserSession().getEffectiveUserName());
} catch (final Exception e) {
// TODO: handle exception
}
}
}
....
21. You may get an error that the method Session.getEffectiveUserName()
is not API. That can be fixed by amending the Java compiler settings, by
changing the setting for forbidden reference to “Warning”.
image:img/domino13.png[13]
22. Right-click on *src/com.paulwithers.hellovaadin* and select *New* >
*Class*. Class it “HelloVaadinUI” and set the superclass as
“com.vaadin.ui.UI”.
image:img/domino14.png[14]
23. Add the following code to the class:
+
[source,java]
....
import com.vaadin.server.VaadinRequest;
import com.vaadin.ui.UI;
public class HelloVaadinUI extends UI {
@Override
protected void init(VaadinRequest request) {
final WelcomeView welcome = new WelcomeView();
setContent(welcome);
}
}
....
This creates an instance of the WelcomeView class just created and loads
it to the page.
24. On the *Build* tab ensure META-INF, WebContent, plugin.xml, src are
all ticked for Binary Build.
25. On the Overview tab, launch the *Organize Manifests Wizard* and
complete.
image:img/domino15.png[15]
26. Select *File* > *New* > *Feature Project*. Call it
com.paulwithers.helloVaadinFeature.
image:img/domino16.png[16]
27. Click Next and initialize from the com.paulwithers.helloVaadin
plugin.
28. Select *File* > *New* > *Update Site Project*. Call it
com.paulwithers.helloVaadinUpdate and click Finish. Click *Add Feature…*
and select com.paulwithers.helloVaadinFeature. Click *Build All*.
29. Right-click com.paulwithers.helloVaadinUpdate and click *Export…*.
Choose *General > File System*. You only need to select the site.xml.
Export to an appropriate location.
image:img/domino17.png[17]
30. In an Update Site database on the relevant server, import the update
site by pointing to the site.xml.
image:img/domino18.png[18]
+
As with any OSGi plugin, you will need to issue “restart task http”
command to the server for the plugin to be available.
31. If you browse to the “helloVaadin” URL on the server (corresponding
to the contextRoot in the plugin.xml), you should now see “Hello
Anonymous” message.
image:img/domino19.png[19]
If you log in or prefix the contextRoot with the filepath of a database
that does not allow anonymous access, you will see a welcome message for
the current logged in user.
