JSP TagLib Bug

I took my taglib's and tried to move them
          over to get them working on 6.0.
          I now get an error:
          Parsing of JSP File '/showdate.jsp' failed:
          /showdate.jsp(1): Error in using tag library uri='date' prefix='/date.tld':
          There is no setter method for property 'datestring', for Tag class
          'com.almaer.taglib.date.ShowDateTag'
          probably occurred due to an error in /showdate.jsp line 1:
          <%@ taglib uri="/date.tld" prefix="date" %>
          However I do have a setDatestring() method. I have tried various taglibs
          that are in production working fine.
          Is this a known bug? Has anyone else run into this?
          I also find that precompile=true in weblogic.xml doesn't seem to do anything
          Who does the QA for this? ;)

Thank you. I changed my setter to be setFoo() and have the attribute foo in
          my tag and it worked. For some reason some values don't work in there. I
          haven't worked out
          if the problem is a) having a variable x and then having a setX() or whether
          it has something to do with the properties of the name that you call it.
          Crazy.

Jsp taglibs in include files not detected, throws errors, no code insight

I have a jsp which is included in all the other jsp. it looks something like this
taglibs.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
test.jsp
<%@ include file="/jsp/menu/taglibs.jsp"%>
<html>
     <head>
          <title>Tours</title>
     </head>
     <body>
<form:form commandName="testCommand">
               <form:hidden path="tour.firstname" id="tour.firstname" />
and so on.
I am having 2 problems
1. the jsp editor show errors all over the place saying
element path not expected
element commandName not expected etc.
2. no code insights.
but if i include the taglib def in test.jsp it dosn't show any error and also provides code insights. but seldom do people include all taglibs in all jsps.
is there a way for Jdeveloper to show code insights in jsp pages which includes a jsp or like xml schemas could be added at some place(tools-pref-xml schemas) and when used anywhere, would provide code insights.

am not sure, try with this
<jsp:include   .../>

JSP Taglib for RSS

Just wondering if anyone else is having better luck - been working thru:
http://developer.java.sun.com/developer/technicalArticles/javaserverpages/rss_utilities/
Each time I try and parse an RSS file I get the following trace:
<rss>
<channel>
<title>
</title>
<link>
</link>
<description>
</description>
</channel>
<item>
INFO: items does not exist or method signature is incorrect
java.lang.NoSuchMethodException
at java.lang.Class.getMethod0(Native Method)
at java.lang.Class.getMethod(Class.java:888)
at com.sun.cnpi.rss.handlers.DefaultElementHandler.startElement DefaultElementHandler.java:91)
at com.sun.cnpi.rss.handlers.DocumentHandler.startElement(DocumentHandler.java:98)
at org.apache.crimson.parser.Parser2.maybeElement(Parser2.java:1477)
... rest of stack trace.
This is tried with 5 or 6 different RSS feeds (0.91 and 2.0) and with both crimson and the latest xerces parsers (stacktrace is the same apart from the parser specific parts - it's always in com.sun.cnpi.rss.handlers.DocumentHandler.startElement(DocumentHandler.java:98)
It appears to be trying to call a method based on the fact that it has seen an items tag (which it hasn't - it's an item tag).
The JSP:
<%@ taglib uri="/rssutils.tld" prefix="rss" %>
<rss:feed
url="path-to-feed"
feedId="intranetRT"/>
<h2>"><rss:channelTitle feedId="intranetRT"/></a></h2>
<rss:forEachItem feedId="intranetRT">
<h3><a href="<rss:itemLink feedId="intranetRT"/>"><rss:itemTitle feedId="intranetRT"/></a></h3>
<div class="item">
<p><rss:itemDescription feedId="intranetRT"/></p>
</div>
</rss:forEachItem>
Maybe of interest - all tried RSS streams work fine for various other RSS readers and return valid from 2 different validators.
Hints anyone?

I try using this tag library, and I get the following on my page:
java.lang.ClassNotFoundException: com.cj.rss.objVariable
as the root cause for this excemption:
org.apache.jasper.JasperException: Failed to load or instantiate TagExtraInfo class: com.cj.rss.objVariable
Do I have a bad "path" set up somewhere? Here's my code:
<%@ taglib uri="/WEB-INF/lib/taglib.tld" prefix="c" %>
<html>
<head><title>Java Feed</title></head>
<body>
<%-- <jsp:useBean id="beanInstanceName" scope="session" class="beanPackage.BeanClassName" /> --%>
<%-- <jsp:getProperty name="beanInstanceName" property="propertyName" /> --%>
<c:setFeed url="http://www2.theserverside.com/rss/theserverside-1.0.rdf" id="A"/>
<p>Title:<c:getChannelTitle feedId="A"/>
<p>Description:<c:getChannelDescription feedId="A"/>
<c:forEachItem feedId="A">
Link:<%=itemLink%>
Title:<%=itemTitle%>
Description:<%=itemDescription%>
</c:forEachItem>
</body>
</html>
It's pretty simple code, and I made sure that the library file (jar) and .tld file were in the /WEB-INF/lib directory, off of the "context" directory or "docroot". I guess I would have gotten a different error if they weren't there.
Any thoughts as to why my server is having problems loading the object:
com.cj.rss.objVariable
It is in my rsstag.jar file. I confirmed it by opening it with WinZip. Here's the reference to it in the rssrag.tld file:
<tag>
<name>setFeed</name>
<tagclass>com.cj.rss.setFeedTag</tagclass>
<teiclass>com.cj.rss.objVariable</teiclass>
<bodycontent>JSP</bodycontent>
<info>parses rss feed</info>
Any information would be greatly appreciated.

Yes, change
<tagclass>testTL</tagclass>
to
<tagclass>yourPackage.testTL</tagclass> and of course recompile class with package declaration and put into package.

What gives? I'm having the same problem with a scriptlet!
This works:
<jsp:scriptlet>
     cntInt++;
     out.println("cntInt = "+cntInt);
</jsp:scriptlet>but this doesn't works:
<jsp:scriptlet>
     cntInt++;
     out.println("cntInt = "+cntInt);
     for(int idx=0; idx<cntInt; idx++) {
</jsp:scriptlet>...it can't seem to handle for loop? Does anyone know why?

JSP taglib tags

hello every one
i am using JSP taglibs in my work and i am trying the example given in book - " JSP The Complete Reference" . example of database operations . In chapter 11.
But when i compile i am getting warning that EVAL_BODY_TAG is deprecated.
so i would like to know what can i use instead of EVAL_BODY_TAG
Thanks
Amol

Use either "EVAL_BODY_BUFFERED" or "EVAL_BODY_AGAIN".

EL or RT expressions for JSP taglibs

I have a simple question
We all know that there are two ways to implement a JSP page. either RT expressions or expression language (EL). I have done plenty of research and I am comfortable at creating custom JSP taglibs that support both RT and EL. What I want to know is which if them is used more commonly?
Its useless to right 2 seperated libs, since you can pass variables from EL to RT and vice versa, so I want to have only one tag library, but I dont know how I should implement it EL or RT.
What is used more often and why? What is the advantages of using one over the other. Thank you!!!

RT was the original way; it required scriptlets, which everyone hates.
EL is the new way; it helps eliminate scriptlets, which everyone loves.
EL is the method of choice; even moreso when JSP 2.0 is finalized, it allows them to be used more freely (not just in tags)

How Do I Specify uri in JSP taglib Directive to Point to the Jar File

I put the trail-taglib-0.2.jar file in the MyApplication/WEB-INF/lib directory.
Because the .tld is included in the trail-taglib-0.2.jar, I added the following In the MyApplication/WEB-INF/web.xml file:
< filter >
< filter-name > trailFilter < /filter-name >
< filter-class > org.osjava.taglib.trail.OriginalRequestFilter < /filter-class >
< /filter >
< filter-mapping >
< filter-name > trailFilter < /filter-name >
< url-pattern > *.do < url-pattern >
< filter-mapping > How do I specify the uri in my JSP @taglib to point to the jar file? I think I did not get the path right:
< %@ taglib prefix="trail" uri="trail-taglib-0.2" % >

Your advices have been very good. Problems get solved one at a time.
1. Now, the taglib.tld in the WEB-INF directory can be found; however, another problem occurred: XML parsing error on file /WEB-INF/taglib.tld: (line 11, col 17): Element type "display-name" must be declared.
2. no matter where I insert the filter and its mapping in the web.xml file,
<filter>
   <filter-name>trailFilter</filter-name>
   <filter-class>org.osjava.taglib.trail.OriginalRequestFilter</filter-class>
</filter>
<filter-mapping>
   <filter-name>trailFilter</filter-name>
   <url-pattern>*.do</url-pattern>
</filter-mapping>The server cannot find the Struts tag libraries. If I remove the filter tag and its mapping, the server does not complain anymore. I checked the DTD, the filter tag and its mapping tag should be before the servlet tag and servlet mapping tag. But, it does not work.

I18n jsp taglib, hot update

Hi
I'm investigating use of the jsp taglib i18n that comes with Personalization
server.
Is there any way of updating the .properties files so that the changes come
thru reliably without restarting the server?
A kind of reloadCheckSecs=0 like for jsp files would be good.
Does such a functionality exist?
Has anyone implemented such a functionality?
Alternatively, is the code for the taglib available?
Regards
Alex

If you need more information, don't know what I mean or whatever, please ask.
I realy need this but don't know how to do...

1) To handle <bodycontent> you should inherit from BodyTagSupport
class
2) You should use your bean like: <td><atmjsp:ATM/></td>
with closing slash - it's bodyless tag - this mistake
causes JSP compiler to report error
Enjoy!

In Jsp TagLib how can I get the Attribute value (like JavaBean) in jsp

Dear Friends,
TagLib how can I get the Attribute value (like JavaBean) in jsp .
I do this thing.
public void setPageContext(PageContext p) {
          pc = p;
pc.setAttribute("id", new String("1") );
          pc.setAttribute("first_name",new String("Siddharth")); //,pc.SESSION_SCOPE);
          pc.setAttribute("last_name", new String("singh"));
but in Jsp
<td>
<%=pageContext.getAttribute("first_name"); %>
cause null is returing.
Pls HELP me
with regards

First, there is no need to pass in the page context to the tag. It already is present. How you get to it depends on what type of tag:
Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/SimpleTagSupport.html]SimpleTagSupport
public class MyTag extends SimpleTagSupport
public void doTag()
    PageContext pc = (PageContext)getJspContext();
    pc.setAttribute("first_name", "Siddharth");
    pc.setAttribute("last_name", "Singh");
    pc.setAttribute("id", "1");
}Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/TagSupport.html]TagSupport or it's subclass [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/BodyTagSupport.html]BodyTagSupport the page context is aleady declared as an implicit object:
public class MyTag extends TagSupport
public void doStartTag()
    pageContext.setAttribute("first_name", "Siddharth");
    pageContext.setAttribute("last_name", "Singh");
    pageContext.setAttribute("id", "1");
}In each case, this sort of thing should work:
<mytags:MyTag />
<%= pageContext.getAttribute("first_name") %>I

JSP Taglib Issues

Hey there. I am deploying a WAR file on OC4J 9.0.4.0, and it has a taglib that I wrote as well as the "core" tld. I have made sure that my tag classes, my tld file, and my web.xml conform to JSP 1.2 as JSP 2.0 does not appear to be supported. I receive the following error:

I can verify that all the files are in the right places as well.
I have exhausted all avenues as far as determining why this error is occurring, but I cannot solve it. Worse yet, we have a deadline fast approaching. I know this isn't much, but I was hoping the stack trace could at least help you point me in some direction. Any insights you have out there are greatly appreciated.
Thanks and Happy New Year.

Hello MackDe,
If the rquired libraries are not updated in the NWDI system. Plz ask your Basis team to update the shr/ext component from the SAP Market place. After the update plz create the project of shr/ext and synch it, then all the required libraries will be added to the classpath automatically in NWDS. Do the build and deploy and test the application. If not plz update the latest errors that you got.
Thanks,
Pateelu

JSP taglib prefix issue

Placing the prefix before the URI as shown below works when deploying to Tomcat
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
but does not work for OC4J.
For OC4J , placing the prefix after URI works , but will not work under Tomcat
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %>
Any ideas?

Placing the prefix before the URI as shown below
works when deploying to Tomcat
<%@ taglib prefix="spring"
uri="http://www.springframework.org/tags" %>
but does not work for OC4J.It should not matter which one is placed first. If it does not work for OC4J, it should be, as my first thought, caused by some factors other than the order of attributes. Can you confirm that once if the uri and the prefix are switched in a single jsp file, then that jsp file will be working correctly? If so, what is version of your oc4j?
As far as I have tried on oc4j 10.1.3.0.0, there is no such problem.

</attribute>
</tag>
</taglib>
Thanks,

Does your web server have an internet connection, or is it just a localhost on a development machine? If it can't see the internet, it can't find the DTD:
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
...which may be your problem. A workaround is to download the above file, put it on your webserver somewhere, and change this url to point to the new location.

JSP---Taglib

HI
I am new JSP .Can any one tell what is taglib
with regards
Amutha

hi,
what is taglibAdvantage of a JSP is its ability to implement a custom tag library. These custom tags allow page designers to abstract themselves from a complex set of logic; include this tag and it will have this effect on the web page.
