Re: Converting Java Code in JSP to JSTL

[Bill Siggelkow]

You cannot call static methods with JSTL 1.0. The simplest option is to 
create a JavaBean that you place in some application scope that wraps 
the static method call with a normal JavaBean getter instance method.

That being said, if you truly are formatting stuff then use the JSTL 
formatting tags if you can. If you are using JSTL 1.1 then you can 
create a function tag. Another alternative is to use the "bind" tag in 
the Jakarta Taglibs "unstandard" library ...

All in all, your best bet is probably one of the first two options (your 
own JavaBean or use JSTL fmt library).

Something like this:
<c:out value="StringUtils.abbreviate(${aTopic.subject}, 30)"/>
Is this possible?
Thanks,

I was told that JSTL can convert most of the Java code
in JSP.  I still have some problem with initializing
variables and if statments; for example, I do not know
how to write in JSTL of the following:
1. int i = 0;
<c:set var='i' value='0'/>
2. i++;
<c:set var='I' value='${i + 1}'/>
3. String prevArticle = null;
<c:set var='prevArticle'/>
4. if ( numberOfPosts - 1 == 1 ) {}
<c:if test='${numberOfPosts} - 1 == 1'>
5. if ( nextTopic != 0 )
<c:if test='${nextTopic != 0}'>
6. String threadID = String.valueOf( threadID_int );
<c:set var='threadID' value='${threadID_int}'/>
7. if ( threadRows.size() == 0 ) {}
<c:if test='${not empty threadRows}'>
8. if ( previousOffset >= 0 || nextOffset >= 0 ) {}
<c:if test='${previousOffset} >= 0 || ${nextOffset} >= 0'>
9. if ( prevArticle != null ) && ( !article.equals(
prevArticle ) ) {}
<c:if test='${not null ${prevArticle}} && ${article != prevArticle}'>
The article != preArticle I am not quite sure.
