Up until now my experience with eclipse link has been statically mapping bean properties to XPath and the occasional JavaXMLTypeAdapter in order to control the format of a properties value.

Now I've been given the task to map a DOM that was explicitly constructed procedurally and so it's not a 1:1 mapping but more conditions involved.

I have to construct XML that looks like this.

<A>
<B>
<C>
<D>
bean elements.

....

when I have

@XmlRootElement(name="A")

Q1. how can I avoid declaring the full path for each of my bean elements? Since they all will appear under D or lower.

....

Q2. I have to do conditional logic based on a beans properties

so depending on securityType attribute I have to emit
either

when securityType is set to OPT

<SecurityType>
<Option Value="OPT">
<PutCall Value="1"/>
<Maturity>
<MonthYear>201810</MonthYear>
<Day>26</Day>
</Maturity>
<StrikePx>161.5</StrikePx>
</Option>
</SecurityType>

when securityType is set to FUT

<SecurityType>
<Future Value="FUT">
<Maturity>
<MonthYear>201810</MonthYear>
<Day>26</Day>
</Maturity>
</Future>
</SecurityType>

Q3. Another conditional scenario I have is

based on the value of orderType I have to do emit

when orderType = 1

<OrderType>
<MarketOrder Value="1">
</MarketOrder>
</OrderType>

when orderType = 2

<OrderType>
<LimitOrder Value="2">
<Price>0.08</Price>
</LimitOrder>
</OrderType>

when orderType = 3

<OrderType>
<StopOrder Value="3">
<StopPx>0.08</StopPx>
</StopOrder>
</OrderType>

when orderType = 4

<OrderType>
<StopLimitOrder Value="4">
<StopPx>0.08</StopPx>
<Price>0.08</Price>
</StopLimitOrder>
</OrderType>
