Using PDI plugin

[sergei.sheinin]

Is there a good example that I may refer to in how to use PDI plugin for reading a vCard? I have following code where the "application.output(c.addresses)" produces empty array output "[]":

Code: Select all

/**
* @type {String}
*
* @properties={typeid:35,uuid:"1099B45F-9838-4A55-80BC-767252D996C8"}
*/
var vCard = 'BEGIN:VCARD\n\
VERSION:4.0\n\
N:Gump;Forrest;;;\n\
FN:Forrest Gump\n\
ORG:Bubba Gump Shrimp Co.\n\
TITLE:Shrimp Man\n\

/**

*/
function test(){

   var c = plugins.PDI.VCard(vCard)
   application.output(c.validate())             // <null>
   
   application.output(c.addresses)              // []
      
   
}

A vCard can contain more than one "card". So you start reading using

Code: Select all

var cards = plugins.PDI.AddressBook("F:\\test.txt")
var card = c.VCards[0];
application.output(card.addresses);

I'm not sure the underlaying library fully supports vcard 4...

[sergei.sheinin]

I changed the vcard code to v2.1 but the result didn't change. I would like to be able to use vCard from a text variable if possible for the test rather than file. I think that is what "plugins.PDI.VCard()" function is for, correct me if I'm wrong.

Code: Select all

var vCard = 'BEGIN:VCARD\n\
VERSION:2.1\n\
N:Gump;Forrest\n\

No, the empty VCard constructor is for creating new vcards...

[sergei.sheinin]

May I have a suggestion how to create vcard object from a string please?

In my code I have "var c = plugins.PDI.VCard(<string>)" and it doesn't seem to work.

[patrick]

Write it to a file and read it from there

[sergei.sheinin]

Ok, although I expected "plugins.PDI.VCard(<string>)" to produce a vcard object it didn't work. I am now trying to read from file and get null pointer error:

Code: Select all

   var f = plugins.file.convertToJSFile('C:\\projects\\docs\\100bob\\vcard.txt');
   application.output(f.size())                                   // DISPLAYS CORRRECT SIZE, so the file is accessible and was read

   try {
     var y = plugins.PDI.AddressBook(['C:\\projects\\docs\\100bob\\vcard.txt']);}
   catch(err) {
      application.output(err.message)}                  //  java.lang.NullPointerException: null
   
   try{
      var x = plugins.PDI.AddressBook([f]);}
   catch(err){application.output(err.message)}         // java.lang.NullPointerException: null
   

I also tried with f.getBytes() with same null pointer error. The content of 2.1 version vCard is above in the thread (the file has "\n\" endings removed).

Please advise and if possible provide a working example.

Why are you passing an array? Just look at my code example. All really simple. I tested my code above and it worked as expected. P.S.: Don't forget to register the plugin, otherwise you get null all over.

[sergei.sheinin]

If I don't pass it as array I get "The function AddressBook([Array<None>]) is not applicable for the arguments (String)".

I register plugin at top of the code and it returns "true".


Please help.

[patrick]

Why don't you simply try my example above?

The plugin is quite old in terms of Servoy's plugin API. It still runs with Servoy 3.5 and was never updated to the latest plugin API to not break compatibility. It uses an old fashioned way of receiving arguments as an object[] that is routed internally depending what kind of object[] comes in. So ignore that warning and just use my code example. You will not get rid of that warning.

Code: Select all

try {
     var y = plugins.PDI.AddressBook('C:\\projects\\docs\\100bob\\vcard.txt');}
   catch(err) {
      application.output(err.message)} // java.lang.NullPointerException: null


This also produces null pointer. Any ideas?

[patrick]

No, because yesterday exactly that worked for me nicely.

Anyway, this doesn't really belong into the Servoy forum since it is not related to Servoy. I suggest you contact support@servoy-plugins.de and attach the servoy_log file, so they can see what is Null there in your case.

[sergei.sheinin]

May you by chance provide a vcard file with which it worked?

[patrick]

sure. it's the same you use, that vcard from wikipedia.

I wrote to support@servoy-plugins.de and they sent me pdi.jar in attachment. When I replaced the file it worked without any problems.
