dsp:equalEJB determines whether two EJBs have the same primary keys and saves the Boolean result to the object named by the var attribute.
Attributes
TagVariable:varorid(Required)
You must define an EL variable or scripting variable:
Attribute | Description |
|---|---|
| Names an EL variable. When you use |
| Names a scripting variable, which scriptlets and expressions can access at runtime. |
VariableScope:scope
The scope attribute determines what resources can access the named EL variable. Options include: page, request, session, or application. Omitting this attribute causes the default, page, to be used.
FirstEJBtoCompare:ejb1(Required)
The ejb1 attribute holds one EJB argument.
SecondEJBtoCompare:ejb2(Required)
The ejb2 attribute holds one EJB argument.
Example
<dsp:equalEJB var="frisbeeAdvertisement" ejb1="${winter}"
ejb2="${currentSeason}"/>
<c:choose>
<c:when test="${frisbeeAdvertisement}">
Try out for Ultimate Frisbee in April!
</c:when>
</c:choose>
When the current season is winter, the two EJBs have the same primary keys so this code sample advertises try outs for the ultimate Frisbee team.
