You cannot use one jsp tag to supply another jsp tag with a value for an
attribute.
Some solutions are:
1) Use an html (rather than a jsp) tag:
<input type="text" name="licenceCount" value="<c:out
value='${purchaseForm.licenceCount}'/>" size="3" readonly="<c:out
value='${purchaseForm.newPurchase}'/>" maxlength="5"/>
2) Use a bean defintion and an rt expression:
<bean:define id="readOnly" name="purchaseForm" property="newPurchase"/>
<html:text property="licenceCount" size="3" readonly="<%=readOnly%>"
maxlength="5"/>
3) Use struts el tag:
<html-el:text property="licenceCount" size="3"
readonly="${purchaseForm.licenceCount}" maxlength="5"/>
