An example for creating an logging aspect.

Alternatively, you can create aspects by the supported archetypes. Once after having Fuji, at least M4 version, here are the steps that are need to create Logging Aspects Project:

!!Tokens of logging aspect
A token is enclosed by curly brackets, {} and is evaluated for the value. A token can embed other tokens. The tokens are processed recursively until there are no valid tokens to evaluate.
!Built-in tokens
The following are built-in tokens.
role<br/>
endpoint.name/endpointname<br/>
message.type/messagetype<br/>
exchange.id/exchangeid<br/>
endpoint<br/>
service<br/>
operataion<br/>
pattern<br/>
status<br/>
error<br/>
fault<br/>
interface.name/interfacename<br/>
!in-place tokens
XPaths expressions and property expressions can be used as an in-place token, which will be evaluated while logging the content.
#XPath expression in-place token example: {xpath://Employee/FName}
#Property expression in-place token example: {property:groupid}
!!!Example of Logging Aspect
If the properties are,
{{{
log.content = Attempt to invoke {operataion} on service {endpoint.name}., The message of { xpath://Employee/FName} with {property:groupid} is being processed and his Address = {Emp.Address} . He is from {Country}.
log.token.Emp.Address={Emp.FullName} {Emp.Company}, {xpath://Employee/Street}, {xpath://Employee/City}, {xpath://Employee/State} - {xpath://Employee/ZIP}
log.token.Country = {xpath://Employee/Country}
}}}
and if the input is:
{{{
<Employee>
<EmpId>123</EmpId>
<FName>Ramesh</FName>
<LName>Dara</LName>
<Company>Sun Micro Systems</Company>
<Street>800, Royal Oaks Dr</Street>
<City>Monrovia</City>
<ZIP>91016</ZIP>
<State>CA</State>
<Country>USA</Country>
</Employee>
}}}
The output would be:
{{{
Attempt to invoke {http://fuji.dev.java.net/application/myJRuby}requestReply on service transform_endpoint.
The message of Ramesh with 402af89d-cf28-4211-bb60-484b44fdb710 is being processed and his Address = Ramesh Dara, Sun Micro Systems, 800, Royal Oaks Dr, Monrovia, CA - 91016 . He is from USA.
