I had the same problem. In your .tld change tagclass to tag-class and bodycontent to body-content and that should do the trick. The names slightly changed for JSP spec 1.2.

How to use JSP custom tag lib in PAR file?

Hi All,
I am trying to customize mastheaderpar file. For that I have downloaded relevant par file and making the changes accordingly.
As part of the changes I would require to use JSP custom tag library in my par file.
I have the TLD file and relevant classes in the jar file. I would like to know where and what kind of modifications have to be done to use the jsp custom tag library.
I tried modifying some things in portalapp.xml but was not successful.
Please help me on how to proceed with this? It would be great if you can provide the xml entry to use this tag library
Thanks
Santhosh

Hi Johny,
Thanks for the reply. Actually I am able to change colors etc. with out any problem.
My requirement is to use XMLTaglib in mastheader par file. This tag lib is from apache tomcat. I have the relevant TLD and class files. I copied TLD file into taglib dir of portal-inf and class file in src api.
And I have added the following line in portalapp.xml under component-profile section of default
<property name="tlxtag" value="/SERVICE/Newmastheader/taglib/taglibs-xtags.tld">
Is this the right way to use tag lib? Actually before adding this line I used to get the error saying "Error parsing taglib", but now the error does not occur and I am getting new error. This is an exception in one of the taglib classes.
Could any one provide me some inputs on how to check this error?
Thanks

Re: Using ScopeCache custom tag

Hi, I am quite new to ColdFusion and I have a calendar that
is quite slow due to the cfloops it uses to build the calendar. As
the page does not change very often I wanted to use Raymond
Camden's ScopeCache custom tag. However, for some reason the custom
tag was not getting picked up from the custom tag folder on the
server. I have successfully used components so have tried to

Hi, thanks to both of you for your help. I reverted back the
custom tag and it was picked up this time - I don't know what
happened before. The functionality works as expected but I have hit
another problem and I am hoping I can tap your combined ColdFusion
wisdom to solve!!
The calendar returns leave records for staff and filters the
records using a querystring variable appended when the user clicks
on a particular month. However, what members of staff the user sees
depends on the data held in the users' session variables based on
their authority. The reason I wanted to use caching is because the
page takes a good ten seconds to run because of the use of cfloops
for the members of staff and the days of the week to dynamically
build the page. Using the custom tag would have worked if all
members of staff saw the same calendar data and could only see one
month. Can you see anyway I can speed up the page and do you think
caching is the way forward here?

Using a custom tag with a 2.3 servlet descriptor BUG?

Hi,
I just developed a Custom Tag and I'd like to use in my jsps.
If I add the jsp in my JDev project with the custom tag when I try to build the project I got this error:
Error(11): oracle.xml.parser.v2.XMLParseException: Invalid element 'listener' in content of 'web-app', expected elements '[context-param, servlet, servlet-mapping, session-config, mime-mapping, welcome-file-list, error-page, taglib, resource-ref, security-constraint, login-config, security-role, env-entry, ejb-ref]'.
It seems like when the jsp parser encounters the line with taglib it tries to parse the web.xml against a 2.2 version of the dtd. My web.xml begins with the correct dtd version (2.3). Can anyone tell me if this is a bug and eventually tell me how to solve it?
thanks,
Giovanni

I repost this issue again, now with a simple test case.
If I wrote a simple custom tag:
import java.io.IOException;
import javax.servlet.jsp.tagext.TagSupport;
public class MyCustomTag extends TagSupport {
public int doStartTag() {
try {
pageContext.getOut().print("FOO");
} catch (IOException ioe) {
pageContext.getServletContext().log(ioe.getMessage(),ioe);
return(SKIP_BODY);
with the associated tld:
<?xml version = '1.0' encoding = 'windows-1252'?>
<taglib>
<tlibversion>1.0</tlibversion>
<jspversion>1.2</jspversion>
<shortname>try</shortname>
<uri>try</uri>
<info>A short description...</info>
<tag>
<name>mytag</name>
<tagclass>MyCustomTag</tagclass>
<bodycontent>EMPTY</bodycontent>
</tag>
</taglib>
and a jsp using the custom tag:
<%@ page contentType="text/html;charset=windows-1252"%>
<HTML>
<HEAD>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=windows-1252">
<TITLE>
Hello World
</TITLE>
</HEAD>
<BODY>
<H2>
The current time is:
</H2>
<P>
<% out.println((new java.util.Date()).toString()); %>
<%@ taglib uri="try.tld" prefix="try" %>
<try:mytag />
</P>
</BODY>
</HTML>
all runs fine if I have a web.xml with the dtd version 2.2
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

I get the error I report in my last post. (the jsp doesn't compile) If I remove the custom tag from my jsp all works fine (filters, listeners,etc). In my project settings I use the 2.3 version of servlet.jar instead of the ServletRuntime that comes with JDeveloper.
Can anyone tell me how to resolve this issue (Using simple custom tag with a web application using the 2.3 servlet specs)?
Thanks in advance,

Error processing CFX custom tag "CFX_iMSMail".

Hi
I am testing a CF application and this is the error I get.,
when I am trying to 'register for a certain event'.
Error processing CFX custom tag "CFX_iMSMail".
'The CFX custom tag "CFX_iMSMail" was not found in the custom
tag database. Please be sure to add custom tags to the database
before using them. If you have added your tag to the database then
you should check the spelling of the tag within your template to
insure that it matches the database entry.'
Text
The following are the lines of code in one of my cf pages
that seem to be responsible for causing the error.
486 : spooldir="#application.mailPath#/Out/"
487 : priority="0"
488 : smtpfrom="#listPart.contactEmail#"
489 : header_from="#Trim(listPart.contactName)#
<#Trim(listPart.contactEmail)#>"
Is there any fix for the CFX custom tag problem or is there
anything I am missing. I am using CF 7.0 on Windows XP
thanks in advance

You must register CFX custom tags in the CF Administrator.
Until you do, they will not be found by the server. That's what the
error message is trying to tell you.

Can anyone help me in running this example.

an uri is not an url,
in your web.xml you should have something like
<taglib>
<taglib-uri>http://yourtaglib/taglib</taglib-uri>
<taglib-location>/WEB-INF/yourtaglibtld</taglib-location>
</taglib>
that uri should be same as in the tld.file and same as in the <%@ taglib tag

Custom tag help

Hi there,
I was wondering if someone might help me construct a custom tag handler class that either allows or denies access to a given JSP page? I'll start by showing the code I want to replace in all my JSP pages:
<%
String companyID = (String)session.getAttribute("companyID");
String administratorID = (String)session.getAttribute("administratorID");
if(companyID == null || administratorID == null)
     out.println(ServletUtilities.headWithTitle("ACCESS DENIED") +
    <body><h1>ACCESS DENIED</h1><a href=\"/scholastic/Login.jsp\">Return to Login Page</a></body></html>");
     return;
else
%>What this code is doing is extracting from the session object the companyID and administratorID. Both of these were placed into the session object when the user logged into the system. As we know, when a session times out, these IDs no longer exist, thus I test for null. If either value is null, then I create HTML markup that instructs the user to login again.
So, what would be better is a custom tag that I can call just once, like so:
<%@ taglib uri="stlib-taglib.tld" prifix="stlib" %>
<stlib:allow_admin_access />
The behaviour I want is to prevent the rest of the JSP from loading if the custom tag is unable to obtain the companyID and administratorID from the session object.
I've not create custom tags before and would like some guidance on the tag handler class. Perhaps declare it:
public class AllowAdminAccess extends TagSupport
public int doStartTag(){...}
public int doEndTag(){...}
}Please advise,
Alan

webapps/scholastic/WEB-INF/classes/servlets.class
Now, when I launch the browser and try to go to http://localhost:8080/scholastic/Login.jsp AccessFilter kicks in and since there is no User object in the session object yet, authorized will remain false. The logic continues to the line:
filterConfig.getServletContext().getRequestDispatcher(login_page).forward(request, response);
But in the end I wind up with a Page Not Found 404 error.
I tried changing the <param-value>/scholastic/Login.jsp</param-value> to just <param-value>/Login.jsp</param-value> but this resulted in an endless loop condition with the Tomcat container. "/scholastic/Login.jsp" is the correct relative URL. So I'm stuck at this point.
Please advise,
Alan

Retriving Portlet preference information using a custom tag

Hi ,
I am trying to create a custom tag which will be used to retrieve portlet prefrence information (administrative pref, community pref, user pref etc.).
In the displayTag method i am not able to create the Portlet request object.
I am getting the IEnvironment reference by calling the method GetEnvironment().
IEnvironment has methods called currentHTTPRequest() and currentHTTPResponse() which returns IXPRequest and IXPResponse object,
But to create a portlet context I need HTTPRequest and HTTPresponse.
If some one is aware of any other method for creating the portlet context from IXPRequest and IXPResponse object. please share as it will be of great help.
Thanks in advance!!

Thanks for reply!
Actualy I am trying to retrieve the Prefernces ( Community Preference, User Preference, Administrative Preference ) values in a custom Tag.
But I did not find any way in native APIs to retrieve the preferences.
So I was wondering if somehow I can established a remote session using IDK to retrieve the same.

Using a custom tag inside another tag's attribute value?

Hi all,
I have a custom tag, mytag:link, whose use currently looks like this:<mytag:link path="/images/logo.gif"/>Nevermind what the tag does. Here's its TLD:<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN" "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
    <tlib-version>1.1.1</tlib-version>
    <jsp-version>1.2</jsp-version>
    <short-name>My custom tags TLD</short-name>
    <tag>
        <name>link</name>
        <tag-class>test.MyLinkTag</tag-class>
        <body-content>empty</body-content>
        <description>...</description>
        <attribute>
            <name>path</name>
            <required>true</required>
            <rtexprvalue>true</rtexprvalue>
        </attribute>
    </tag>
</taglib>I want to replace the path argument of the mytag:link tag to the result of the evaluation of another tag (a SiteMesh decorator tag) like this:<mytag:link path="<decorator:getProperty property="meta.logo"/>"/>This, of course, doesn't work, as I get the following error:org.apache.jasper.JasperException: /decorator.jsp(34,92) equal symbol expected

     com.opensymphony.module.sitemesh.filter.PageFilter.doFilter(PageFilter.java:59) If I replace the call to the other tag with
<mytag:link path="<%=someVariable%>"/>then it all works fine. This behavior seems correct, as the SiteMesh getProperty tag is writing its output to the Writer returned by pageContext.getOut() as it should. As such, this seems to be a design question, then. How are you supposed to do this?
Thanks in advance,
Matthew

Note that I've also posted a question to the SiteMesh user forums about this. It has more information about the motivation of this question.
See http://forums.opensymphony.com/thread.jspa?threadID=8561
I'm still looking for an answer, though.

Error in JSP Custom Tag Program

Hi Dear,
when I compile my JSP Custom tag program on weblogic Its give that Error..
Parsing of JSP File '/Home.jsp' failed: /Home.jsp(-1): cannot load TLD: weblogic.xml.dom.ChildCountException: missing child tagclass in tag
probably occurred due to an error in /Home.jsp line -1:

Please resolve my issue..

I had the same problem. In your .tld change tagclass to tag-class and bodycontent to body-content and that should do the trick. The names slightly changed for JSP spec 1.2.

Cannot use cfx_image custom tag

While trying to use cfx_image tag I am getting the following error and anyone give me an idea what I am missing?
Thanks

Yes there was a problem with bits. I was trying to run a 32bit dll in 64bit CF.
Fix:
Rather than reinstalling my CF I gave up using cfx_image tag as I found a better option.
The builtin CF function ImageResize:

<cfset uploadedImage=ImageNew("#attributes.imagepath#\#photo#")>
<cfset ImageResize(uploadedImage,"#attributes.thumbsize#","","highestQuality",1)>
more details about this function can be found at:

Compile Errors when Generating Conditional Tag Help File

Ok, here is a recap of everything I have done. I started over from scratch. Unzipped the Help File into C:\Users\edwinwood\Documents\My RoboHelp Projects\Adobe RoboHelp 9 folder. Went to the properties SSOL Help Development folder and unchecked read only. Opened RoboHelp 9 as an administrator, went to File->Open and opened the help file. The first thing that pops up is a message stating this is a help file made with an older version of RoboHelp(v8) and must be upgraded(v9). I hit ok. The next pop-up is this “Unable to connect to the project $/SSOL HelpDevelopment@:ROBOSOURCE in version control. Would you like to browse for it?” I hit yes and the next pop-up just asks do you want to discontinue connection attempts in the future. I hit no. After that is usually where the files that are write protected pop-up but they didn’t this time. After about 5 minutes It will say upgrade complete. I shut down RoboHelp go into the language folder copy the robohhre.lng and paste it into the root folder. Like I said this file has nothing in it. I reopen RoboHelp as an administrator and open the project again. I then go to View->Pods->Single Source Layouts. Double click the Tag1 Remove Hickory Tech and then click save and generate. At the very end of the compile process I still get Template Errors...

It should work well, if you use
<?xdoxslt:set_variable($_XDOCTX, 'var', xdoxslt:convert_case(ssCivil,’UPPER’))?>

Error Using Custom Tag

I am trying to use a custom tag but receive an error when I use it on a jsp page.
I have a tag handler class file, tag library descriptor file, specified the path to the .tld in the web.xml file.
The error implies that it cannot find the SimpleTag.class file, though I put it in the \webapps\examples\WEB-INF\classes\ directory.
Here is the error. Does anyone know what else it could be?
org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:
C:\jakarta-tomcat-4.0.1\work\localhost\examples\jsp\jspVisual\ch10\using_0005ftag$jsp.java:63: Class org.apache.SimpleTag not found.
SimpleTag_jspx_th_myFirstTag_SimpleTag_0 = new SimpleTag();

I could not see any obvious mistakes. But what you could try, in order to isolate the problem, is to bypass the web.xml. In other words access the TLD directly by doing this in your JSP
<%@ taglib uri="/WEB-INF/jsp/tag_library_descriptor.tld" prefix="myFirstTag" %>
if that does work then move the your TLD out of the jsp folder and into WEB-INF , then try
<%@ taglib uri="/WEB-INF/tag_library_descriptor.tld" prefix="myFirstTag" %>
Maybe someone else has better idea.
