JSTL question

[Abhishek Sharma]

Hi Ranchers,

Here is one question on JSTL core tags.

    
Which is true for JSTL core iteration tag. (choose two)
 
1. It may iterate over arrays, collections, maps and strings.
2. The body of the tag may contain EL code, but not scripting.
3. When looping over collections, a loop status object may be used in the tag body.
4. It may iterate over map, but only the key of the mapping may be used in the tag body.
5. When looping over integerss (for example begin='1' end='10'), a loop status object may not be used in the tag body.

As per my observation it should be 2, 3.


Please correct me if i am wrong.

To avoid scripting,declaration and expressions only we are going for custom tags..

[madhav changala]

My answer is 1,2

As only Simple tags only doesn't accept scripting.. before simple tags. i.e classic tags are accepting scriptlets and expression etc..

Could any one confirm this..


Thanks®ards

yes..

simple tags dont accept scripting !

[Abhishek Sharma]

well...ok, are you sure about Strings also (as specified in option one) and what do you say about option 3, can't we use "varStatus" inside the body of iteration tag. ???

<table border=1 cellspacing=0 cellpadding=3>
<tr bgcolor="#CCFFFF">
<td><B>Loop Counter</B></td>
<td><B>Token</B></td>
</tr>
<c:forEach var="token" items="abc,def,ghi,jkl,mno,pqr,stu,vxyz" varStatus="statusKeeper" >
<tr>
<td>${statusKeeper.count}</td>
<td>${token} </td>
</tr>
</c:forEach>
</table>

works!

My take is on 1 and 3. varStatus certainly can be used in the body, so 3 is correct.

Regarding 2, are you sure scripting is not allowed in JSTL core tags?
I don't remember it is mentioned somewhere.
