4.1.2 Send Message Client Sequence<br />
Figure 4.2 shows the sequence diagram of the send message client thread. The send message<br />
client thread will be created by the data manager. It waits for a configurable period of time until<br />
it starts querying the database for new arrived test results. The query is done by the DBSession<br />
object, which creates a list of XML messages represented by the Send Message List Object. The<br />
message objects will be represented by the DOM document model implemented in the DOM<br />
Parser Xerces (Java Version).<br />
The SendMessage class provides a method for converting the DOM object into a string and sends<br />
this string to the remote gateway interface.<br />
