XPages series #4: Backing Bean Management with XPages

Dan Soares — Mon, 22 Apr 2013 22:48:02 +0200

Karsten, I was able to resolve this by changing the implementation to get an array of Strings to be used as selectItems attributes.

Thanks,

Dan

XPages series #4: Backing Bean Management with XPages

Dan Soares — Mon, 22 Apr 2013 19:21:31 +0200

Thanks so much Karsten. I have another use case scenario.

How would I use the Actor bean to populate the values of a keyword field?

For example, I have a combo box. For the values, I am using the 'Add formula Item' option. And this is my SSJS:

Actorlist.setConnDB("jdbc:sqlserver://XX.XX.X.XX:1433;DatabaseName=Test");

Actorlist.setConnUserName("sa");

Actorlist.setConnPassword("password");

Actorlist.setSQLQuery("SELECT DISTINCT Name FROM TestTable");

Actorlist.actors;

I get the error - 'edu.phc.students.model.actor incompatible with javax.faces.model.SelectItem'

What am I doing wrong?

Thank you,

Dan

Dan, I think this should work:

var actorList=ActorList.getActors();

for (var i=0; i
var currActor=actorList.get(i);

var currId=currActor.getId();

var currFirstname=currActor.getFirstname();

var currLastname=currActor.getLastname();

//do something with the actor here

}

Karsten,

Forgive this very basic question but using SSJS, how would you iterate through the list of actors and their properties in the example above?

I have understood and implemented your your datatable example. I now want to (from a button) act on each element of that Java Array.

Thanks,

Dan

Hello Petter,

yes, I will publish the demos and blog about them. I am currently on vacation, but I will try to start translating the slides and blogging somewhere middle/end of April.

Hello Karsten,

Great presentation ! Do you plan on making the demo database available for download as well ? :-)

Thanks !

A current benchmark

Your need differs a bit from mine, I run Mac all the way and wish to cram every bit of performance I can out of Wintendoze.

Here's a benchmark comparing the two:

I would also recommend looking at the author's other stuff on his website (in the "experiments" section):

Quick tip: Fixing Dojo drag and drop issues in a Windows 8 VMWare on the Mac

Karsten Lehmann — Thu, 7 Mar 2013 11:01:14 +0200

You may be right, I used Parallels a few years ago. Switched to VMware to have the same VM format in Mac and Windows host environments so that I can run the same VM on my desktop machine. Did not notice a big difference when I switched to Fusion (V3 I think).

Joacim Boive — Thu, 7 Mar 2013 10:53:13 +0200

I would recommend using Parallels instead of WMWare.

I've tried both and find Parallels to be the better choice. Feels more complete and runs faster. You'll be hard pressed to find any reviews that favour VMW over Parallels.

Easy to import your VMW images as well.

And the above isn't an issue running Windows 8 in Parallels, just tested. ;)

I would take a look at this:

{ Link }

That solution seems to handle connection pooling automatically and should be available as open source.

Otherwise you would need to make sure yourself that your connection is closed after reading the data from the JDBC driver and you might get some troubles with SecurityManager restrictions.

Haven't really played with JDBC in XPages so far.

Karsten,

I was able to get it working. I just renamed the property to id (lowercase). Like you said, it was probably a typo somewhere.

I have another question that kind of goes beyond the scope of this article. I want to integrate this XPage with a student information system to pull data into the datatable.

I have the JDBC code to query the MS SQL db and generate the result set. I just don't know how to pass the connection parameters to the bean or how to call the bean from the lookup button.

Would appreciate some pointers.

Thanks,

Dan

Karsten Lehmann — Mon, 25 Feb 2013 17:58:57 +0200

Dan, do you have a method "getStudentID()" in your bean? Maybe it's missing or there is a typo in the code (Id - ID?)

Dan Soares — Mon, 25 Feb 2013 16:57:36 +0200

Hi Karsten,

This was an excellent article. I'm working through implementing the code, but I get the following error:

HTTP JVM: com.ibm.xsp.webapp.FacesServlet$ExtendedServletException: javax.faces.el.PropertyNotFoundException: Error getting property 'studentID' from bean of type edu.phc.students.model.Student

If I remove reference to studentID and and only get firstName and lastName, the method works great and the datatable is populated.

Thanks,

Dan

I am trying to use Couchbase as my NoSQL db but ran in to the issues you described in another blog entry about the permissions. I would like to learn how to create a Domino OSGi Plugin to bypass the issue. Any chance you would create a step by step for that and/or share the code for you MongoDB to learn from?
