XPages Designer Plugin 4 Eclipse – The Basics!

First, and please keep it in mind, I’m talking about XPages. Nothing more, nothing else. Some years ago, in an open discussion between the XPages Community and the XPages Development Team, we agreed that it would have a huge value, to have a XPages Designer which is based on the latest and greatest Eclipse Release and can be installed as Plugin / Addon.

But where to start? Try to make the IBM Domino Designer loadable from Eclipse? Extract the relevant Plugins from the IBM Domino Designer and make them installable? Or? All this approaches seems to be a pain. So I started to RETHINK the whole stuff.

What does the IBM Domino Designer make, when he has to build an XPages Application?

  1. Convert all XPages / CustomControls to Java Files
  2. Compile all Java Files to classes
  3. Attach all the results in the .NSF Files on the right place

You think this is too simple? Things are become complex without our help🙂 But let’s assume that this is the way how the IBM Domino Designer builds the XPages Stuff. If you want to proof it, open a Notes Application in the navigator view in the IBM Domino Designer and you will find the following:

xpde-01

Adminsettings.xsp becomse Adminsettings.java (xsp Package) and then Adminsettings.class & Adminsettings$AdminsettingsPage.class

So how does the IBM Domino Designer this? And is there some special knowledge needed to figure this out? I try to explain it with a simple example. The XPages is an XML file, which describes the combination of Components. Lets assume we have in that file the component . The IBM Domino Designer parse this file and will hit the tag. Based on the xp the IBM Domino Designer searchs all Plugins that are responsible for the XP prefix. If you build your own Plugin, you have to specify an own namespace, like wgcpoi. wgcpoi holds all tags for POI4XPages. But lets go on with the xp:panel. It will figure out which plugin is responsible and the .xsp-config file in the plugin describes what with a panel tag has to be done. It will figure out that a panel tag is hold be a component and it will also give back the name of the class that is responsible for the xp:panel.

With the knowledge of the class name, the IBM Domino Designer build a function that creates a UIComponent (the root of all components) and instantiate the class like this

private UIComponent createPanel(....) {
         UIPanelEx panel = new UIPanelEx();
         panel.setId("myId");
         panel.setStyleClass("superstyle");
         return panel;
}

For each property that is defined in the XML there is a corresponding setter defined in the .xsp-conf. This is the way how the designer builds the Java .class. I know it sounds simple, but there is some more complexity.

Now this class is be compiled and then the whole package is stored in the .NSF.

Already open sourced!

The fun part now is, that the transformation of .xsp -> .java is already open sourced. It is in the XPages Bazaar available.

XPages Designer Plugin 4 Eclipse

Based on all this I’ve builded an Eclipse Plugin that does the following:

  1. Build an NSF like project structure
  2. Transform .xsp -> .java
  3. Compile .java -> .class
  4. Build a .xpjar of all the files and publish this to a IBM Domino Server with some build instructions

On the IBM Domino Server runs a Plugin that receives the .xpjar File (via http) and does

  1. Parse the build instructions (JSON)
  2. Access or create the target Database
  3. Loop thru the .xpjar and produce the neede “Note” Documents in the NSF to store the produced and compiled files.

While I get you some Insides now, I’m working on the first Alpha release. All I’ve pointed out works like a charm, but the preparation of the environment is not “Alpha” ready. But stay tuned😉

And have fun

Building NSF using the maven headlessdesigner plugin from OpenNTF

Building NSF using the maven headlessdesigner plugin from OpenNTF

Sometimes I think it would be good to have an assistant who does finalize all my tasks. Specially the tasks, I was not aware that I did not deliver all information to the community. And what a shame, one of my most favorite project was such an unfinished business. The real bad thing was, I didn’t blog about how to use all the code I’ve developed while I was last time in Ireland to meet my friends at IBM.

But a nice blog post by Eric McCormick (https://edm00se.io/xpages/headless-dde-and-jenkins/) reminds me about my duties. Now Eric, time to explain you how simple you can build full XPages Applications with the headlessdesigner-maven-plugin:

The Project Setup

I’m using the JUnit4XPages Project to explain how to build the example database with the headlessdesigner-maven-plugin. This project is fully mavenized and uses the tycho plugins to build the plugins, feature and the updatesite. The project is with a parent – child structure organized. The following stuff in the parent is relevant for the building of the XPages Application:

2016-03-26_22-08-18

ddehd.designerexec and ddehd.notesdata are in this example “externalized” to the environment variables notes-designer and notes-data. Both values are import to invoke the headlessdesigner-maven-plugin. With mvn clean install -Dnotes-designer= -Dnotes-data= can the build be customized.

2016-03-26_22-09-05

There is an additional profile, which is only executed if the notes-designer variable is seted. This has the good behavior, that the NSF is only build, if you have specified the location of your IBM Domino Designer. The module org.openntf.junit.odp is with purpose at the end of the  sequence, because we need the updatesite first.

The org.openntf.junit.odp contains in the sub directory “on-disk-project” the on-disk representation of the NSF, which means all the code. This Code need the org.openntf.junit.xsp.feature installed on the IBM Domino Designer environment to build. This is the reason, why we build the updatesite before.

The headlessdesigner-maven-plugin supports the deployment of the feature. The pom.xml for org.openntf.junit.xsp.odp looks like this:

2016-03-26_22-07-40

ddehd.odpdirectory points to the on-disk-project. Pro Tip: Take this in a subdirectory otherwise the IBM Domino Designer eats your pom.xml😉.

ddehd.targetdatabasename contains the name of your resulting database.

maven.build.timestamp.format is used to build a timestamp that matches the format of the feature.

feature.url points to the file location of the updatesite. This is very powerful, because you can also point to a URL and I think also to a p2 repository. This means for XPages Application, you are capable to point to all the updatesites of the dependencies you have (yes there is a reason why every new plugin project at OpenNTF should have a p2 repository, and why we push them on the openntf.org website, more about this later)

feature.version calculates the current version number. We are using for this the org.codehouse.mojo / build-helper-maven-plugin

In the plugins section is the org.openntf.maven / headlessdesigner-maven-plugin with all additional configurations. I want to point to the features / feature block, where you can define all the features that has to be installed for the headless designer to be able to build your application.

templateBuildNames and templateBuildVersion is a powerful add-on from Jesse Gallagher and results in the following information on the database:2016-03-26_22-14-32

With all that configurations, I’m now able to start the build direct from my eclipse

2016-03-26_22-53-32

And it will build the full project:

maven-output

Done…. (btw. the headlessdesigner-maven-plugin is available in the maven central repository, no installation needed for this, only the IBM Domino Designer must be installed).

Have Fun!

A developers dream – for sure

OpenNTF is in the middle of his biggest transformation since the beginning. Core of the this transformation is building communities around visions, problems and projects. This needs communication…. Continious communication, a flow of questions, answers and ideas.

But how to communicate continuously, several topic’s, restricted content, open content, and involving everybody who is interested to become a part of this community? I the middle of this storm of changing culture and using technology, Jesse discovers “by accident” slack. We (Jesse and I) decided to register openntf.slack.com, to get some experience and figure out if slack would help us.

2 weeks later, after some testing, which includes also the integration of our Atlassian suite, it was clear – a developers dream. Mulit channel / topic and content federation… how wonderful.

But how to on board as many people as possible. At this point, Declan Lynch came on the plan and pointed to https://github.com/rauchg/slackin. A node.js project with an auto deploy to Heroku. But Heroku offers a free offering with 6h downtime in 24h. Sorry, not an option and to be honest, that has not looked like the next challenge I want to conquer.

But Declan explained that this is a node.js app, it could also run on IBM Bluemix….. And YES I’ve a IBM Bluemix Account. But node.js? And how to give this “Slackin – Thing” some parameters during the startup?

As a good conditioned Java Developer, my first step was to download the needed eclipse plugin. Go to IBM Bluemix, build a new Organisation and then create a node.js app. Not a boilerplate, only the runtime.

Next step was creating a JavaScript Project in Eclipse, configure the IBM Bluemix Server, Change the ProjectFacet to node.js, assign the project to IBM Bluemix Server. And….. nothing happens, but hey it didn’t crash the whole Bluemix Environment😉

Let’s go to github and clone the slackin project. I copied the files, including all Licence stuff to my project and all was pushed directly to IBM Bluemix. But the application fails to start…. I did expect this, but how to give this node.js program the variables? (Yes, I’m a bit a newbie about node.js…)

Let’s open the IBM Bluemix console and take a look there. What’s that, there is a point called environment variables. Let’s give it a try. I’ve defined the 2 parameters with the name that was given in the app.json in the IBM Bluemix Console, filled them with the accurate values and restarted the app……

…. And wow, IT WORKS. How cool is that. No Plan of node.js, using an OpenSource project from github, no installation of any server and the application is running in less than an hour. Okay thats definitely also a developers dream.

The integration on the OpenNTF Page was done some Minutes later and look at this:

SLACKIN

And now join openntf.slack.com and following the OpenNTF Community.

Another nice journey with Maven – or how to sign a jar file

Yes I love Maven, for sure. Maven gives you the capability to build project everytime the same and in every environment. I often explain Maven as a brilliant facility manager, who is able to put all the build, test, package and delivery instruments togehter and then build all the stuff according to your building instructions.

But what if I have to sign a JAR file with a code signer certificat? And this certificate is owned by another company, and they will not provide this certifacte to me. How can I setup a project with Maven that let me build and sign the project by a selfsigned certifacte, while my customer other my build server can use the code cert?

First step…

I need a selfsigned code certificat in a keystore. Read the following tutorial on how you can do this http://www.jade-cheng.com/uh/ta/signed-applet-tutorial/. Add this keystore now to the project. My keystore is named awfstore

Once we have done this, let the Maven project know that we want to sign the jar file by adding the following snipped to the build section in the pom.xml.

mj1

We are using the “maven-jarsigner-plugin”. The configuration is done by some variables, starting with “sign.”. The values for this variables are definied in the properties:

mj2

You can build now the project and it will sign your project with the certificat awf from the awfstore. Replace this values, with your values. But how can we achieve that a Buildserver like Jenkins or Atlassian Bamboo can use other values?

Add the following definition to your pom.xml:

mj5

This will activate the Profile compSignerKeyStore, which will override the variables with new settings. This settings can be placed in the setting.xml of your Buildserver or of any developer. It can looks like this:

mj4

Have fun

Christian

Currently recovering

Dear All,

It’s a while ago, since my last post. The best excuse is, that I really had a lot of projects to push forward and less of time to talk and blog about. But that’s only the half of the story.

Last month, on June 9. I was in Spain for a customer meeting. It was a really good meeting and it was nice to be there. But during the meeting, I was getting cold. Real cold and my first tought was: what a strong air conditioning. But in fact, my body temperature was rising and the cold was a result of the fever. We went to the airport after the meeting, and I realized that also the airport has an air conditioning. After standing a while outside in the warm spanish sun, we took our flight back home. My wife picked me up I had a night with nice fever driven dreams.

The day after, at the evening, we went to the hospital. My right leg was twice thick then my left one, but I was more caring about the high fever and the diarrhea. Fortunately the medical team and the doctors at the hospital didn’t ignore my leg and took the swollen leg at their top priority. According to some swiss hospital rules, I was moved to the isolation station.

A team of medical doctors started to figure out why my leg was so swollen and why all me blood doesn’t look really good. They started with a antibiotics therapy, which had a strong impact to the fever. Day by day the size of the leg was shrinking, but the heavily forced skin has built some bubbles, which were filled with some liquid. A part of the medial team where really excited about this fact, because the took some of the liquid from the bubble and could analyze what was happened to my leg (It was fun to see what passion these doctors had, because of this bubble and the opportunity to know more).

Flesh eating bacteria! What a radical diagnose. I heard also the “normal” and the worst case scenario of this disease. To be honest, in the worst case, I wouldn’t be able to write this blog entry. I wanna thank first god the almighty father and creator of heaven and earth, for my recovery, for his carrying, for all the moments where I could feel his presence and for pointing me to this wonderful song which gave me hope and patient (https://www.youtube.com/watch?v=A-1MR5JAu2M). Thanks to all friends who prayed for me. Thanks to the medical team and the doctors at KSW Winterthur, you did a great job. And thanks to my company, who is giving me the time to recover and handles all my projects. And last but not least to my family, thanks for every visit, SMS and your prayers: I love you!

My leg ist recovering. Fever is gone, but the skin of my leg has still the nice color scale from a bright orange to a dark yellow. But the skin is also recovering and I’m able to type and think. My action circle is currently my home and I will remain at home, until my leg is recovered. It’s hard to stay at home and not enjoy the swimming or other outdoor activities, but patient is the best friend currently.

I hope that I can now catchup with all the interesting projects I was involved and a lot of news around XPages, Java and some new technologies.

All the best

Christian

PS: Sorry Bruce that I missed your birthday, be blessed!
