hi ohadas,
really i don't see wht you need to use dynamic value params. If u have these...
<query-method>
<method-name>findByMe</method-name>
<method-params>
<method-param>java.lang.String</method-param>
</method-params>
<ejb-ql>select object(o) from Pecnctemp o where o.key == ?1</ejb-ql>
then you can call to the finder using the concret value of the array
myeb.findByMe(myArray[0])
or
myeb.findByMe(myArray[1])
or......
What i saw necesary it's dynamic queries. For example, i would like to do something like this....
<query-method>
<method-name>findByMe</method-name>
<method-params>
<method-param>java.lang.String</method-param>
</method-params>
<ejb-ql>select object(o) from Pecnctemp o where ?1</ejb-ql>
and ?1 will be myColumn=myValue
