JSTL and SAXON 8.7

How can I get the JSTL X library to use the SAXON 8.7 parser? I would like to use some of the xpath and xslt 2.0 features.

hi,
u can use the jstl1.0 or jstl1.1 to use the xpath. and there is a tag <x:transform> in jstl xml tag libray to use the xslt.
Here, is the jstl1.1 download link,
http://jcp.org/aboutJava/communityprocess/final/jsr052/index2.html,
In order to use jstl (core, format) tags, u need to copy
jstl.jar
standard in to ur lib directory.
In order to use the jstl (xml) tags, u need to copy,
jstl.jar
standard.jar
saxpath.jar
jaxen.jar
xalan.jar (for jstl1.1)
regards,
Pavan.

Question regarding JSTL and function calls

Hello
I'm quite new to JSTL and I'm having a problem accessing a function when I want to pass argument to that function.
Im using MVC where my M (model.jsp) can be accest from my V (view.jsp) by doing ${model.(parameter/some function) }
in my M I have a couple of getMethods() (example: getThisInfo() ) and som control methods like "isSomethingValid(arg1)"
my question is lets say I want to access my "isSomethingValid(arg1)" and arg1 should be the value of "getThisInfo()" I thought I could do like
${model.somethingValid($model.thisInfo)} but it isnt working I get:
"Unable to parse EL function ${model.somethingValid(model.thisInfo)}"
I know that the syntax above is a mix of scriptlet and JSTL but I dont know how to or if its even possible to achieve this?
Thanks for helping me!
Best Regards/DS

By default, EL can only access getters and setters on objects.
It can not execute general methods on an object.
You can define function libraries that call static methods
You have to write the method as static, and then declare it in a tld.
public boolean checkValid(Model m, Info i){ ...}
and then you could invoke it something like
<%@ taglib uri="myfunctionstaglib" prefix="myfunctions" %>
${myfunctions:checkValid(model, model.thisInfo)}

Convert HTML ASCII codes with JSTL and Apache Taglibs?

I am building a web application using JSTL and some of the Apache Taglibs, so these are the taglibs I have at my disposal currently. What I am looking for is the ability to handle the ' that appears in submitted search strings which contain the ' character. SQL seems to be able to handle other special characters (such as &, [, ", etc) but I can't get it to get along with the '. I have tried using a <string:replace replace="'" with="\'"> to escape the ', but this doesn't seem to work either. Any suggestions? Let me know if you need more information to be able to fully understand the situation.
--Ioeth

By the way, the search string that a user enters is getting Tokenized using " " as the token and then fed directly into multiple SQL LIKE comparisons based on how many tokens were found.

Problem using jstl and displaytags

Hi all,
I am using display tags taglib for generation of table. One of the columns has to be shown with the hyperlink attached to it. In order to acheive this i am using jstl taglib together with displaytags
<display:table name="reportList" id="row" requestURI="viewengagementstatus.do" style="width: 100%;">
<display:column title="Period" sortable="true" style="text-align: center;" >
<a href="/jsps/reportsummary.do?eid=<c:out value="${row.eid}" />&reportId=<c:out value="${row.ReportID}" />&reportPeriod=<c:out value="${row.targetDate}"/> " target="_blank"><font size="1"><c:out value="${row.targetDate}"/></font></a>
</display:column>I am using jstl1.1.2.jar for jstl.
When i run this on Weblogic10 and windows OS i am able to view the results. On performing the view source on the IE window, i get the following:
<td style="text-align: center;">
<a href="/jsps/reportsummary.do?eid=78004&reportId=104093&reportPeriod=Nov-2008 " target="_blank"><font size="1">Nov-2008</font></a>
</td>but when the same code is run on the Weblogic deployed on the Linux machine, i am not getting the links and the name:
the view-source of the application deployed on the linux machine shows:
td style="text-align: center;">
<a href="/jsps/reportsummary.do?eid=&reportId=&reportPeriod=" target="_blank"><font size="1"></font></a>
</td>Any Ideas why this is occuring?
Any help would be appreciated

You should be using the one or the other, not both. Since your actual code shows that you don't need the jstl/core_rt taglib (you're using the JSP EL ${ } in JSTL tags rather than scriptlets <%= %> ), just remove that taglib declaration and continue using the jstl/core taglib.
You should also rather place both the JSTL and standard JAR in the classpath of the application server. In case of Tomcat, put it in its /lib directory. Then remove all unnecessary JSTL and Standard JAR and TLD files from your whole webapplication project and also remove any related entries from the web.xml of your webapplication project. To use JSTL you only need to put the JAR files in the classpath of the application server and define the taglib in your JSP. Nothing less and nothing more. If you're using JSTL 1.2 rather than JSTL 1.1, then you need to remove the standard.jar file too since it is already merged in the jstl-1.2.jar file.
Oh, the web.xml should also be declared that way that the application server uses at least servlet 2.4.

J2EE, JSTL and JSF questions

I am trying to learn J2EE/JSTL/JSF and have quite a few general questions. Any help on any of these is appreciated.
1) Is there a way, just by using J2EE/Java to "manipulate" an XML file. Not just parse and read it's data but actually add nodes to the file?
2) I've been reading quite a bit on JSTL and JSF recently. Is JSF supposed to be an alternative to Struts and JSTL an alternative to scriptlet coding?
3) I am also working on creating a message board but throwing around a couple of ways to implement it. Either (a) using a database to store posts and a JSP interface or (b) using an XML document to store postings. Which of these two seem best or is there a better option?
4) Is there an easy way to call Php from a Java program? I need to invoke a php program when a user clicks on a link on a JSP page I have.

1) The SDK provides JAXP (Java API for XML Processing) in javax.xml package.
2) I wouldn't call it 'alternative'.
3) Your choice. I'd to use a RDBMS. Less overhead, better suited, (much) more functions and better performance.
4) If that program is available on the web, then just invoke a HTTP request. If not, I'd rather to rewrite it to Java.

Difference between JSTL and JSF

Hi
I am little bit confuse between JSTL and JSF. can one tell me what is difference between JSTL and JSF ?
Thanks & regards,
Ben

from suns site
The JavaServer Pages Standard Tag Library (JSTL) encapsulates as simple tags the core functionality common to many Web applications. JSTL has support for common, structural tasks such as iteration and conditionals, tags for manipulating XML documents, internationalization tags, and SQL tags.

Juggle between jstl and jsp!

I have a list of items and whose size is obtained by jstl as follows:
<c:set var="num" value="${fn:length(form.namesList)}"/>I have to find the number of blocks using jsp and I am trying as follows which is giving jspException.
<%int numCols = (int)Math.ceil( num / 10.0);%>Can anyone tell me the problem over here?
I need to use numCols to display my results using jstl as follows:
<c:forEach var="y" begin="${1}" end="${numCols }">
</c:forEach>Can juggle between jstl and jsp like this?

This depends on the version of JSP you are using:
If you are using JSP 2.0 (like Tomcat 5), make sure you have downloaded and installed JSTL 1.1 and set the web.xml up to use the Servlet 2.4 specs. Then the code you wrote should work.
If you are using JSP 1.x (like Tomcat 4 and below), make sure you have JSTL 1.0. Then you can only use EL (the Expression Language used to translate ${...} expressions) inside JSTL.
If you want to use EL inside your custome tags, look through the Apache Jakarta sight. Somewhere they have an ELExpression translator (a couple of classes actually - whose full names I forget). These classes will let you take the ${...} expressions in as strings, pass them through the translators and get the correct objects back out.
Or you could go a simpler root:
<mob:whatever object="test" name="newname" />
then in your custom tag:
MyType test = (MyType)pageContext.findAttribute(object);
test.setName(name);

Simple setup problems with JSTL and Tomcat

Hi all, I'm having some problems getting JSTL to work the 1st time. JSTL setup seems to be a common problem for relative newbies, but having read previous threads, I still haven't been able to solve my problem so hopefully someone can help:
the jstl.jar and standard.jar are in my WEB-INF/lib directory, so I don't think it's a classpath problem.
My jsp page has the following at the top:
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>Later, I reference a bean var with :
<c:out value="My var is : ${var.property}"/>In my web.xml I have:
<taglib>
<taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/lib/jstl.jar</taglib-location>
</taglib>And I've placed the actual tld (c.tld) in the WEB-INF directory.
On startup I get the error when compiling the JSP:
No such tag out in the tag library imported with prefix c
Can anyone help here?
Thanks in advance,
Mike

I think this note from the JSTL mailing list by Shawn Bayern, one of the lead developers of Jakarta JSTL and the author of "JSTL In Action", will clarify it:
http://www.mail-archive.com/[email protected]/msg04587.html
Don't put that <taglib> in your web.xml. All the books tell you to do it, but Shawn Bayern has the right answer. The URI should be the one that's in the TLD JAR .tld files.
I use JSTL and Tomcat 4.1.24 without the <taglib>, and it works fine. - MOD

Due to the fact, that org/apache/xpath/XPathException belongs to xalan, i copied the xalan 2.7.0 to the web-inf/lib directory. But this doesn't solve the problem. I'm tried it also with xalan, xerces and jaxp. Again, it doesn't work.
Can anybody help me with this problem?
bye

Couple of things, possibly unrelated, but not sure.
You are using JSTL1.0 uris.
With Tomcat5 you can use JSTL1.1, and the Servlet2.4 spec.
You would use the URI: <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
and also update your web.xml file to declare itself as version 2.4
You shouldn't need any of the xalan xerces or jaxp classes in web-inf/lib.
xerces is by default found in the [TOMCAT]/common/endorsed directory.
The others should be provided with the standard java API.
I would try with minimal jar files in web-inf/lib
Occasionally if you include files twice in the classpath it will create ClassNotFoundExceptions like this.
Hope this helps,

Any reference about JSTL and EL

Hi,
Can anyone suggest me reference about JSTL and EL?
Thanks in advance.
Rgds

Add to those above links:
JSTL : http://java.sun.com/products/jsp/jstl/reference/api/index.html
EL as it applies to JSP2.0:
http://java.sun.com/products/jsp/syntax/2.0/syntaxref207.html#1010662
I particularly recommend you take a look at the JSTL specification. (on the first link of this post)
Maintenance Release = JSTL1.1
Final Release = JSTL1.0
They are quite readable, and have excellent summaries of all the tags and their properties. I refer to them constantly.

What's the replationship of JSTL and Struts

I found the JSTL and Struts are similar,both provied some defined tag libaray,is JSTL defined base on Struts?

The two were developed somewhat independently of each other, and duplicate a lot of functionality. It's probably a "Good Thing"() to use JSTL where possible in order to promote future use.

Problem in the jsp, jstl and java script.

Hi Friends,
I am having one jsp which allows user(Could you please refer to code which is written in my jsp) to enter his username and password i want to get the password in the same jsp and want it to be passed to the custom tag without sending request to the server.Please give me an idea.Thanks in advance.
This is the text field which allows a password.
<INPUT type="password" name="password" size="10" maxlength="29" onblur="chkpwd()" onfocus="this.autocomplete=false" >
and this is the anchor tag which refers as LOGIN BUTTON
<IMG height=19 src="images/submit1.gif" width=106 border=0>
when user clicks on LOGIN BUTTON i am calling one javascript function LOGIN(PASSWORD:) to check the validation if the validation is success then i want to get the password in the same function which is entered .
This is ok i can get the password by "document.formName.password.value" then i need to pass this value to the jstl tag which is our own tag as shown below.
<prefix:tagname value="PASSWORD which is having in the javascript variable".
Please help me .
Quick reply is thankfull.

that's correct. You can use the below code for AJAX request.
<script type="text/javascript">
var httpObject = getHTTPObject();
//create XMLHttpRequest object
function getHTTPObject() {
     var xmlhttp;
     if (window.XMLHttpRequest) // if Mozilla, Safari etc
          xmlhttp = new XMLHttpRequest();
     else if (window.ActiveXObject){ // if IE
          try {
               xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
          catch ( e ){
               try{
                    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
               catch ( e ){}
     return xmlhttp;
//define the function to send the request
function sendRequest(){
    var currDesc = document.getElementById("description").value;
    var URL = "manageMaintAction.do"; //action mapping in your struts-config
    var queryString = "currDesc="+escape(currDesc); //get the currDesc value in your action class like request.getParameter("currDesc")
    httpObject.open( "Post", URL, true );
    httpObject.onreadystatechange = cbFn;
    httpObject.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded");
    httpObject.send(queryString);
//callback fn
function cbFn() {
    if (httpObject.readyState == 4)
         if (httpObject.status == 200)
          var result = httpObject.responseText;
          alert(result);
</script>

Netbeans and saxon

I use saxon to process xml transformation with netbeans but i'm not able
to see errors and any other stuff saxon writes to System.err into netbeans
output window, for example <xsl:message> outputs.
Can anybody help?
thanks

Yep, after I was able to get my classes in a package structure (rather than default package) I discovered that.
I couldn't at first get my classes out of the default package. I am spoiled by IntelliJ which changes/adds package statements when you move classes. Netbeans did not automatically add the package statement when I moved from the default package to a package structure. Nor did it warn me that the classes were missing a package statement and/or the package statement didn't match its package location.

Jstl and jsf problem

i'm programming with jsf and have to use jstl tag
i cant access "var" in jsf tags
how can i use # with forEach items attribute ?
or how can i use $ with jsf tags ?
<c:forEach items"${x}" var="x">
<h:outputText value="${x.documentNo}" />
</c:forEach>

If you're using at least JSF 1.2 with at least JSTL 1.2, you can just use unified EL (the "JSF EL") in c:forEach.
<c:forEach items="#{x}" var="x"><h:outputText value="#{x.p}"/></c:forEach>That said, using c:forEach in JSF is not recommended (as almost every JSTL tag/taglibs, only the Functions taglib is useful). Rather go for an JSF UIData component which does not output anything, such as Tomahawk t:dataList and RichFaces' a4j:repeat. If you're using Facelets instead of JSP, you could also use ui:repeat.

Dreamweaver & jstl and tomcat

Hey,
using Dreamweaver Templates with jstl sql.
If I pull data from my database , and place them into
an unordered list:

<ul>
<sql:query var="rs" dataSource="jdbc/db"> select newsletterid, email from newsletter</sql:query>
<c:forEach var="row" items="${rs.rows }">
<li><span class="date"></span>
${row.email }</li>
</c:forEach>
</ul>

the values inside <li> 's are empty.
When I run it in a non-template page works fine.
Any solutions?

<%@taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/format" prefix="c"%>
<div class="inner">
