Standby Widget goes responsive

The standby widget snippet has need around for a while and doing it’s job in lots of my projects but now more and more of my projects is using bootstrap. So then there was time to also change the standby widget to support bootstrap. This is the first version that will give you a responsive standby “loading” indicator.

IBM Connect and what I would like to be announced

I usually write a little post about what I would like to see an announcement about in January

  1. XPages for Bluemix leaves experimental hopefully goes Gold.
    So we can use it in production
  2. Lowering the price for data cache used when scaling XPages applications in Bluemix
    pricing today is a joke, data cache cost almost equal to a full instance. So if you want to scale into more instances you have to pay double the price of the instance.
  3. NSF database enhancements both functionality and speed
    Move indexes out of the database, joins, better and faster fulltext search
  4. Data service for IBM Cloudant directly in XPages
    Leverage the full potential of Bluemix directly inside XPages
  5. Database converter from NSF to Cloudant
    Cloudant is almost the same as an NSF database but with more speed and without the need to a Domino server
  6. IBM Verse replaces iNotes as webmail client
    The customers need something new and fresh
  7. Public release of Outlook as a mailclient thru traveler 
  8. Java 1.8 support for XPages 
  9. Javascript v8 support in SSJS 
  10. Domino Designer becomes a Eclipse plugin
    Yes please, let’s get rid of the old version of eclipse and give us access to everything new and the possibility to upgrade it. and have several versions on the same machine.

You can probably think of more things you would like feel free to make a comment

Wild click events on my XPage

Today I had a strange issue on an XPage application I was working on I it didn’t matter where I clicked
my button on the form got clicked. Very strange. First thing I started to look for was if I had some onClick event that was bind wrong. Nope that wasn’t the case.

Then I went over to the client side and thought I could find what event listener that was making the call but this doesn’t say anything to me.


Then I started to look at the XSP.Attachevents at the bottom of the xpage

But if you have a large xpage and 20 events attached to it, it’s hard to find what is what. The my suggestion is give you components real names. And it was then I found the problem.
Can you spot the difference

The working client side code
his this the XPage with the faulty code


on’t scroll more spoiler alert










Yes, the partial event listener is bound to an object that doesn’t exist view:_id1:_id5
why you might ask, I found that this happens if a button don’t have a name and is set to do a partial refresh.


Then you will get that you will click the button where every you click on the xpage. Hopefully fixed in a future release with an error or a correctly generated id.

First step how to interact with other Bluemix services

You Bluemix XPage server can interact with other services using the VCAP_SERVICES where all the credentials for contacting other services is stored. This JSON data can be retrieved using

var services = fromJson(bluemixContext.getVCAP_SERVICES());

This will give you a direct access to the connected services credentials and exposed information, the credentials is what I have found updated each time you deploy a new version of you code so you need to use this way to get the credentials.

If you login to your Bluemix dashboard and click on your XPage service icon, you’ll find environment variables in the left hand navigator. This will display the structure of the  VCAP_SERVICES JSON data check it out.

Most of the services has different methods of accessing them, I’m still investigating how to use different services and future posts will show how to use Bluemix services using XPages


Is it possible to kill a XPage for Bluemix instance if it’s gone none responsive

I have seen more than once both of own and other developer experience that a loop in XPages gone bad and you have to kill the server. How can this kind of behavior be fixed in XPages for Bluemix will the dashboard work to “kill” the server?

See the answer

Also see my XPages for Bluemix the questions post lot’s of questions is updated with answers

XPages for Bluemix – The questions

When I started to try out XPages for Bluemix I started to create a list of questions for the future because this is in Beta and between now and Gold release some of this questions would be good to have an answer on.

  • What release cycle could we expect to get for the XPages runtime, in relation of getting new versions of extension library and functionality – Answered a monthly release cycle or synced with openntf extension library upgrades
  • Is it possible to install your own OSGI plugins like Debug Toolbar or the OpenNTF Domino API Answer Yes probably already in the next release
  • How do we run scheduled code that we have runned in agents before – Not at this point but the possibility could be there in a future release Answer
  • How to handle Users/Groups/Roles partial answerGroups is not supported and you are limited to 6 web users in the experimental version of XPages for bluemix
  • How to register users thru code, integrate with LDAP, SAMLNot at this point  partial answer
  • How to control JVM Security
  • How to do an automated XPage build process – Could could add git to a Bluemix project and deploy your code the git See post perhaps we will see a ODP git push to Bluemix in the future that would be great. 
  • How to use other Bluemix Services with XPages Answer Answer2
  • How to package an XPage for Bluemix solution as a temple for multi service deployment
  • can a XPages application be run inside a Docker container
  • How does XPages in Bluemix scale – Answer and a very good one
  • Is the database

I will probably get more questions and will then update this post. I will also add any answers I get to this post. If you know any answer please comment.

XPages on Bluemix a first look deploying app

On friday the XPages runtime on Bluemix was released and also the new version of OpenNTF Extension library that enables to work with.

My first impression is that it works great I haven’t had time to do any deep diving into the new possibilities but I thought I should share as long as I have tried it.

To get it to work you need a bluemix account and install the latest extlib into you designer client when you done that you will get a new entry in your preference in the designer.


I have selected the US South (Don’t know if the XPage engine is deployed in the UK site) write your user name and password and Test Connection

if this is ok your designer is connected to Bluemix

Go to bluemix and setup an XPage Starter app when you have logged in to Bluemix you need to go to catalog and at the bottom click on Bluemix Labs Catalog


inside this beta catalog you will find the XPage Bluemix engine and also a web starter application click on this entry.


Fill out an name for you app at the lefthand side and press Create


Your started application is now being setuped and the next step is to download the webstarter app, I actually don’t know if you need the Bluemix commandline tool and I haven’t been able to download it and had it from before so I couldn’t test with out it, but try without it and let me know.


When you have downloaded the starter code go to designer and in the tools menu


This will start a wizard when you need to specify a path to a bluemix staging area, this area should not be in the client data folder and connect to the bluemix app area.

To deploy your code to bluemix you need to right click on the database and select deploy application remember to sign your database before doing this if you have multiple signers in the application.


The deployment will take very long time and if you check the Bluemix the application will show as started but it’s not. This might hopefully be improved with better status updates in future releases.

This will add the design database if you want to connect to the data nsf you need to go into Bluemix and download a notes id and connect you will find this information below services in the Bluemix dashboard.


It seams like the backend data store for the Bluemix is a Linux Domino server because if you browse it you will find regular databases in the root of the server. It will be interesting to see any performance data from the Bluemix setup.

Also read my XPages for Bluemix the questions

Xpages on Bluemix

Finally did the beta arrive and I wasn’t dissapointed. Setting up the web start app was very simple, a few minor things but no error.

  • Deployment takes very long and the bluemix dashboard log says started but overall status say not started. Should say starting
  • Before deploying remember to sign databas otherwise you will get an error
  • You need to manually setup connection to backend database.

But overall great first release will be fun to see what the future will give us.

Moving on with Excel Export part 6 : But now we Import

The previous 5 steps in this series (part 1 part 2 part 3 part 4 part 5) has been getting data out to excel in different ways this part will show you how to get data back into Domino again thru your XPage, this will give you the possibility to roundtrip data handling. Export all customers mark the rows you have changed and re import the data. Because Apache POI is installed on the server as an OSGI we have access to these classes in all java code on the server and that is what I’m going to show you today and how to upload an Excel file and read some data from a cell.

In the example database for POI4XPages there is a class you really need and that is the ImportAction this is needed to open up a workbook of a xlsx file you don’t need it if you are only using xls. This class is used for changing the classpath of the jvm and some security stuff so you don’t need to modify the java.policy file on your server (Thanks Christian for pointing this out)

We start with some OpenNTF data in Excel


We create an java class

public String getData(java.io.File file,Integer row,Integer cell){

try {

 String inputFile = file.getPath();

 String CellVal=””;

 ImportAction ioAction = new ImportAction();

 HashMap<String, String> hsCurrent = new HashMap<String, String>();

 hsCurrent.put(“FILE”, inputFile);

 workbook = ioAction.run(null, hsCurrent);

 if (ioAction.hasError()) {

   Exception exLst = ioAction.getLastException();



 Sheet worksheet=workbook.getSheetAt(0); 

 Row rowdata = worksheet.getRow(row);

 Cell celldata = rowdata.getCell(cell);

 CellVal= celldata.getStringCellValue();


return CellVal;

}catch(Exception e){

return “”;


lets look at the parts of this class

 ImportAction ioAction = new ImportAction();

 HashMap<String, String> hsCurrent = new HashMap<String, String>();

 hsCurrent.put(“FILE”, inputFile);

 workbook = ioAction.run(null, hsCurrent);

 if (ioAction.hasError()) {

   Exception exLst = ioAction.getLastException();


This is the magic call the the ImportAction class that will create a Excel POI workbook Object.

The following rows will get the first sheet in the excel file get the first row and the first cell and return the string

Sheet worksheet=workbook.getSheetAt(0); 

 Row rowdata = worksheet.getRow(row);

 Cell celldata = rowdata.getCell(cell);

 CellVal= celldata.getStringCellValue();

Now we need to create the XPage to enable the upload of the Excel file


The interesting part is behind the read button onclick event


var con = facesContext.getExternalContext();

var request:com.sun.faces.context.MyHttpServletRequestWrapper = con.getRequest();

var map:java.util.Map = request.getParameterMap();

var fileDataName = getClientId(“fileUpload1”) ;

var fileData:com.ibm.xsp.http.UploadedFile = map.get( fileDataName );

if( fileData == null ){



var tempFile:java.io.File = fileData.getServerFile();

var Excel=new com.xpagedeveloper.ExcelData()


We get the uploaded file in fileData and retrieve the actual file using fileData.getServerFile() remember that this file is a server based temp file and with that I mean that you will not get the same same on the file as it was when the user uploaded it. And next I create an object of my class and call the getData function with the java io file object the row and the cell number remember that this has a zero based index so 0,0 is actual row 1 and cell 1, this is the result I get when running the code against the Excel sheet


If you are going to loop thru a full excel sheet you probably need to rewrite the code but this will give you a hint where to begin.

Moving on with Excel Export part 5 : XPages Export

In the previous parts (Part 1 Part 2 Part 3 Part 4) we covered plain export, styling your exports and doing selective exports. Today I want to show you how to create more advanced and flexible way to get your data using a java object that we use for the export.

We start by creating 2 java classes one for the export and one of the Export Data


Then in each class add implements Serializable and the private variable on the row below. This is so the java VM can swap the data out disk if needed.







We will start by creating our data class, very simple. Check what type of data you want to export in each column, in my case I want to export


And then we use the generate setters/getters function in DDE by right clicking in the source window


And select all variables you want to autogenerate setter and getters for an click on OK


Time to create the getData function in the Export class the important thing here is that we return a a java object of the type List.


I also create the function as static because I will only run this function and return the data once. This is the code for the export class. The important thing to point out is

The I create the Exportdata object on each row and store it in the RowData variable

And when I have populated it I add it to the Data ArrayList Object the is returned from the function at the end.

In my Excel export component in All properties datarowexport and I select to create a wgpoi:ListObjectDataSource.screen194

And click on the buildValues property to add some source


And we add this simple code to get the data from the Java objects returned you can expand you getData class and sending in filter parameters from the XPage as we did in Part 4 of this series but in this case the filtering will be done in java.


But wait, you might say how do we populate the column data. That’s the great part of the implementation. You write the name of you variable in you data class and the getter will do the rest. so in this case it will call getName from your row class that is returned.


With this new way of exporting you can combine the data from different sources not only one as I’ve shown in the past parts of this series of posts and giving even better exports to you users.

Integrating a better export into your application will make your users happier
