JSTL comparision doesn't work with jdeveloper 10.1.2.2.0

Question

Hi,
can somebody explain me why comparision are not working with JSTL. I quess reason is the type of the variables, but how can I solve it?
Is the anyway to cast to same object-type?
I try also compare directly with bindings, but didn't work either. That why I use temporary page scope variables.
<c:set var="comp2" value="${bindings.Organisation}" scope="page" />
<!-- prints "-203-", which is correct -->
<tr><td> </td><td>
-<c:out value="${comp2}"/>-
</td></tr>
<!-- loop over possible values -->     
<c:forEach var="RowTL" items="${bindings.OrganisationCode.rangeSet}" >
<c:set var="comp1" value="${RowTL.KarvTunnusnumero}" scope="page" />
     <!-- print "-203-11" when reach correct item which should match -->
<tr><td> </td><td>
-<c:out value="${comp1}"/>-<c:out value="${RowTL.KarvKoodiarvo}"/>
     <!---- true always with fixed value - not reasonable -->
<c:if test="${comp2 == '203' }">
<c:out value="11111111"/>
</c:if>
     <!---- true with correct item, with fixed value - not reasonable -->
<c:if test="${comp1 == '203' }">
<c:out value="22222222"/>
</c:if>
     <!---- false always althouhg printed values with correct item are "203" = "203" -->
<c:if test="${comp1 == comp2 }">
<c:out value="33333333"/>
</c:if>
     <!---- false always althouhg printed values with correct item are "203" = "203" -->
<c:if test="${comp2 == comp1 }">
<c:out value="4444444"/>
</c:if>
</td></tr>
</c:forEach>
thanks PLa

Works fine, thanks,
Now it is comparing wtih string values I guess.
Do you know any good source where can I read about those object types of bindings? I tried also debugger to investicate the structure of object, but debugger didn't show anything.
