Reading vCards with the PIM API (JSR 75)

[yoadg]

Hi,

I am trying to read a vCard through the PIM API (JSR 75):

void addContact(String vCard) {

PIMItem[] items = PIM.getInstance().fromSerialFormat(
new ByteArrayInputStream(vCard.getBytes()), "UTF-8");
if (items != null && items.length > 0) {
Contact c = (Contact) (items[0]);
...
}
}

However, when I try to run it on Nokia 6630, I get a Null Pointer Exception from the first line. I verified that the vCard parameter is not null and valid.

Any idea what could be the cause for that?

Thanks,
Yoad

hi Yoad,

I have an idea how you can test that (if it works at all on your device),
because "fromSerialFormat" is accompanied with "toSerialFormat" you could probably write test case for your device, that is read contact, write it and then recreate it, that way check if api is working fine on that device,

Hi Yoad,

If you're sure you're talking about Nokia 6630 (and not 6630i), it doesn't support JSR-75. See the specs for Nokia 6630 - http://www.forum.nokia.com/devices/6230

There's no support to PIM API on Nokia 6630, unfortunately.

Hope it helps

Hi Juarez,

I am talking about Nokia 6630, which supports JSR-75:

The link that you provided is for Nokia 6230.

Thanks,

Hi Yoad,

Yes, i've read it wrong, forgive this misundertanding. Yesterday was a busy day and I was tired then...

"I get a Null Pointer Exception from the first line"

Well, based on your report it seems that PIM.getInstance() is returning null some how.

Also try to confirm API availability by using System.getProperty("microedition.pim.version") and make sure everything is OK.

Hi,

I solved this problem. The Null Pointer Exception was because of an empty line at the beginning of the vCard. It seems like a bug in the implementation of JSR 75 on this platform.

When I removed the empty line, I encountered another problem with the vCard format. I was trying to parse a vCard that I received through the network form a Windows server. The problem was that the vCard lines ended with a LF ('\n'), while the Nokia implementation expects a CRLF ('\r\n').

Thanks,
Yoad

Hi Yoad,

Thanks for sharing this info. Also, I am glad you managed to solve the problem.

hi guys,
I've looked into vCard specs linked in Nokia docs as implemtation:
http://www.imc.org/pdi/vcard-21.txt
and it uses CRLF, eg:

The paradigm of an electronic business card is related to the concepts of aQuoted-Printable lines of text must also be limited to less than 76 characters. The 76 characters does not include the CRLF (RFC 822) line break sequence. For example a multiple line LABEL property value of:
123 Winding Way
Any Town, CA 12345
USA
Would be represented in a Quoted-Printable encoding as:
LABEL;ENCODING=QUOTED-PRINTABLE:123 Winding Way=0D=0A=
Any Town, CA 12345=0D=0A=
USA

All literal property names are valid as upper, lower, or mixed case.
ws		= 1*(SPACE / HTAB)
	; "whitespace," one or more spaces or tabs
wsls		= 1*(SPACE / HTAB / CRLF)
	; whitespace with line separators
word		= <any printable 7bit us-ascii except []=:., >
groups		= groups "." word
		/ word
vcard_file	= [wsls] vcard [wsls]
vcard		= "BEGIN" [ws] ":" [ws] "VCARD" [ws] 1*CRLF
		 items *CRLF "END" [ws] ":" [ws] "VCARD"
items		= items *CRLF item
		/ item
	; these may be "folded"
item		= [groups "."] name
		  [params] ":" value CRLF
		/ [groups "."] "ADR"
		  [params] ":" addressparts CRLF
		/ [groups "."] "ORG"
		  [params] ":" orgparts CRLF
		/ [groups "."] "N"
		  [params] ":" nameparts CRLF
		/ [groups "."] "AGENT"
		  [params] ":" vcard CRLF

I was trying to parse a vCard that I received through the network form a Windows server.

it rather sounds (because of using LF - "\n") that orignally vCard was created on Unix-based machine not on windows machine (which uses CRLF by default), can it be the reason?
