Reuse web agents that use PRINT - Bean edition
Stephan H Wissel    

Using Java in XPages does have performance advantages especially when you can use EL instead of SSJS. So I created the Java version of the reuse web agents post. You need to copy the Java either into your NSF or include it in your own extension library. Calling an agent is limited to the same database as the XPage resides in, I leave it to an exercise for my readers to improve on that.
You define the Java class as a managed bean:
<managed-bean>
    <managed-bean-name>agentHelper</managed-bean-name>
    <managed-bean-class>com.notessensei.xsp.utilities.LsAgentHelper</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
</managed-bean>
and then simply include (e.g. in the value of a computed field) ${agentHelper.agentResult("SampleAgent")} as EL entry. You have to be careful to ensure your agent doesn't run twice. The agent side adjustments (the LotusScript stuff) is the same as for the SSJS version. The Java version is slightly more flexible since it allows String or Stream results and acting on a new or existing document.

When you learn cooking, there are a few basic skills that need to be in place before you can get started: cutting, measuring, stiring and understanding of temperature's impact on food items. These skills are independent from what you want to cook: western, Chinese, Indian, Korean or Space Food. The same applies to software development. Interestingly we try to delegate these skills to ui designers, architects, project managers analyst or infrastructure owners. To be a good developer, you don't [read] Keywords: ibm development wiki

Flow, Rules, Complexity and Simplicity in Workflow
Wed, Sep 3rd 2014 6:13a   Stephan H Wissel
When I make the claim "Most workflows are simple", in return I'm hit with bewildered looks and the assertion: "No, ours are quite complex". My little provocation is quite deliberate, since it serves as an opening gambit to discuss the relation between flow, rules and lookups. All workflows begin rather simple. I'll take a travel approval workflow as a sample (resemblance of workflows of existing companies would be pure coincidence). The explanation is simple: "You request approval from [read] Keywords: google

Rethinking the MimeDocument data source
Mon, Sep 1st 2014 12:13p   Stephan H Wissel
Tim (we miss you) and Jesse had the idea to store beans in Mime documents, which became an OpenNTF project. I love that idea and was musing how to make it more "domino like". In its binary format, a serialized bean can't be used for showing view data, nor can one be sure that it can be transported or deserialized other than through the same class version as the creator (this is why Serialized wants to have a serialid). With a little extra work, that becomes actually quite easy: Enter JAXB. [read] Keywords: domino lotus notes xpages email java linkedin openntf oracle profile xml

Bikepad SmartPhone mount review
Mon, Sep 1st 2014 10:12a   Stephan H Wissel
This is my field impression of the Bikepad SmartPhone mount having used it for a few weeks on my Montague Paratrooper pro TL:TRThe Bikepad is a highly functional accessory to keep your phone on your bike fully functional. Is has quality craftsmanship and a sleek design. If I had an editor-refuses-to-give-it-back award to give (I actually paid for it), I would award it. I do cycle for longer durations and some rough spots, so I like to keep a phone in reach. Not at last to keep SWMBO updated. [read] Keywords: iphone wiki

Long Term Storage and Retention
Thu, Aug 14th 2014 6:14a   Stephan H Wissel
Not just since Einstein time is relative. For a human brain anything above 3 seconds is long term. In IT this is a little more complex. Once a work artefact is completed, it runs through a legal vetting and it either goes to medium or long term storage. I'll explain the difference in a second. This logical flow manifests itself in multiple ways in concrete implementations: Journaling (both eMail and databases), archival, backups, write-once copies. Quite often all artifacts go to medium term [read] Keywords: domino ibm notes application archive database email office wiki xml

Time stamped encrypted archives
Wed, Aug 13th 2014 9:12a   Stephan H Wissel
Developers use Version Control, business users Document management and consultants ZIP files. From time to time I feel the need to safeguard a snapshot in time outside the machine I'm working with. Since "storage out of my control" isn't trustworthy, I encrypt data. This is the script I use: #!/bin/bash ############################################################################ # Saves the given directory (%1) in an SSL encrypted zip file (%2) within # the personalFiles folder.

Designing a REST API for eMail
Sat, Aug 9th 2014 11:12a   Stephan H Wissel
Unencumbered by standards designed by committees I'm musing how a REST API would look like. A REST API consists of 3 parts: the URI (~ URL for browser access), the verb and the payload. Since I'm looking at browser only access, the structured data payload format clearly will be JSON with the prose payload delivered in MIME format. I will worry about calendar and social data later on. The verbs in REST are defined by the HTTP standard: , PUT, and DELETE. My base url would be http://localhost [read] Keywords: ibm email wiki

Running vert.x with the OpenNTF Domino API
Wed, Aug 6th 2014 1:11p   Stephan H Wissel
In the first part I got vert.x 3.0 running with my local Notes client. The mastered challenges there were 32 Bit Java for the Notes client and the usual adjustment for the path variables. The adoption of the OpenNTF Domino API required a few steps more: Set 2 evironment variables: DYLD_LIBRARY_PATH=/opt/ibm/notes LD_LIBRARY_PATH=/opt/ibm/notes Add the following parameter to your Java command line: -Dnotes.binary=/opt/ibm/notes -Duser.dir=/home/stw/lotus/notes/data -Djava.library.path=/opt/ib [read] Keywords: agent domino ibm lotus notes notes client applications eclipse java openntf

Workflow for beginners, Standards, Concepts and Confusion
Thu, Jul 24th 2014 10:12a   Stephan H Wissel
The nature of collaboration is the flow of information. So naturally I get asked about Workflows and its incarnation in IT systems a lot. Many of the question point to a fundamental confusion what Worflow is, and what it isn't. This entry will attempt to clarify concepts and terminology Wikipedia sums it up nicely: "A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, pro [read] Keywords: collaboration ibm applications email google openntf soa wiki
