Protocols

TCP/IP

The entire communication architecture of the Weblicon PIM system is based on the dominating network protocol TCP/IP. No proprietary protocols are used.

HTTP

The Weblicon PIM uses HTTP as a transport for various contents when communicating between different entities of the system. HTTP is used as the transport for HTML, SyncML, WML, XML and VoiceXML.

IMAP

Instead of implementing a proprietary message store, the Weblicon PIM uses standard IMAP servers for storing messages. The Weblicon Messages module internally uses the JavaMail framework, which supports IMAP 4 using an appropriate adaptor. The Weblicon Messages module uses IMAP to retrieve and store messages and to manipulate the folder hierarchy of the user’s personal message folders.

POP3

The Weblicon Messages module internally uses the JavaMail framework, which supports POP3 using its adaptor architecture. Using POP3, the Weblicon Messages module retrieves Email from external mail accounts.

SMTP

For sending Email and MMS messages, the Weblicon Messages module uses the SMTP protocol by utilizing the appropriate adaptor of the JavaMail framework.

SMPP

Weblicon has implemented an SMPP adaptor for the JavaMail framework supporting the Short Message Peer to Peer (SMPP) protocol. Using SMPP, the Weblicon Messages module can send SMS messages using a vendor-independent protocol. Support for alternative protocols of different SMSC vendors can be implemented.

LDAP

Weblicon fully supports LDAPv3 storing all user, contact and distribution lists into any LDAPv3 compatible directory.

SSL

Secure communication using the SSL protocol is supported for most of the Weblicon client applications including HTML and SyncML.

WebDAV
Weblicon relies on the WebDAV protocol for accessing the user’s personal file storage. Thanks to the industry WebDAV protocol, the Weblicon files module can work with a wide variety of file servers without having to implement vendor-specifc protocols.
