No tag library

I get the following error after I reopened my project and attempted to run it:
"No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during parsing of the .tld file."
"The deferred EL expression is not allowed since deferredSyntaxAllowedAsLiteral is false."
Any help getting this resolved would be appreciated.
Thanks,
Russ

You'd better give us more information:
What version of JDeveloper? What tag libraries are you using? Are you writing JSPs or JSFs? Using JSP format or JSPX? Using the JDeveloper built in libraries, or did you add an additional one?

Connection Pooling and JSP Custom Tag Library - is code (inside) the best way/correc?

Hi, can anyone advise as to whether my tag library code (based
on Apache Jakarta Project) will actually achieve connection
pooling functionality across my entire JSP based application? I
am slightly concerned that my OracleConnectionCacheImpl object
may exist multiple times, hence rendering my conection pooling
attempt useless.

How can i use tag library in the mvc?

hello
in some tag libraris such as jakarta tag library and jrun tag library,there is database
access tag, it provide convenient function to access database from jsp page,but i wonder how can i use such a tag within MVC architecture.
as we know,in MVC architecture,all requests from the jsp pages are submit to the controller servlet,then the controller manipulate ejb to access database,it don't allow the database access from the jsp page.
who can tell me how can i combine the tag library with mvc architecture appropriately?
thank you!

You can't! If you decide to limit the JSP to be part of the View component, obviously you should not include tags that directly access the database. If the strict MVC architecture is less important to you, then the tags can save coding time. It's your choice.

How to use a tag library in multiple web applications?

Morning all,
Environment: Tomcat 5 on Apache2 using Mod_JK connector on Windows XP
I have developed a custom tag library and tested it out and its working great.
Now, How do I use in my other web applications? Do I need to copy the JAR file to webapps\app1\WEB-INF\lib, webapps\app2\WEB-INF\lib etc directories?
The problem with this approach is, if I happen to change the tag library code, I will have to make sure that I remember to copy the new JAR file to the above mentioned directories. Ofcourse I can write a simple ant script that would do it for me, but I was wondering if there was an efficient and yet simple way of achieving the same.
Thanks in advance,
Joe

Thanks Vidyut! You've answered my question.
I placed the jar file in the $CATALINA_HOME/shared/lib directory. But where should I place the taglib TLD file? And how should I reference it in web.xml?
Currently, my web.xml is as follows and it doesn't work.
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

How to add a new tag library into ALBPM 5.7?

Anyone knows how to do it?

Hello,
I think u need to import all resources used by your TagLib as .TLD .JAR to inside process.

Purpose of TAG Library?

What is the purpose of TAG library?
I feel so hard while using Tag library in my JSP pages?

Which taglibrary are you talking about? JSTL?
If so, its purpose is just to control the flow of code logic and the data output in JSP. It is less or more a replacement of scriptlets, which are been discouraged since a decade. Scriptlets are considered a bad practice. Taglibs (and EL) forces you to write clean and well-MVC-formed JSP code. The JSTL core, format and functions taglibs are extremtly useful. The JSTL sql and xml taglibs are intented for quick prototyping only, in real you should be using Java classes for this to avoid tight coupling of database/business/model/view logic.

This may not solve your problem, but WL8.1 SP1 seems to have a problem with
          closing tags.
          Where you are using:
          <randME:number id="random1" range="10000000-99999999"/>
          ...try this instead:
          <randME:number id="random1" range="10000000-99999999"></randME:number>
          This problem is fixed in SP2.

Update: I just looked up the WL version and it's 8.1 sp3
          So, I guess, JSTL 1.1 (which includes jstl fn tags) is not supported by WL.... Someone correct me if I am wrong.
          Thanks,

"No tag library could be found with this URI" error while compiling jsp

I am using WebLogic Server 9.2 MP1, JDK 1.5.0_09, Struts 1.3.5
          I am pre-compiling jsp pages with wlappc ant task. However, I got following errors when a jsp page contains ant taglib:
          No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during parsing of the .tld file.
          The jsp page looks like:
          <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
          wlappc complains taglib could not be retrieved from this uri. Actually, since Struts 1.3.5, those ".tld" files are contained in strust-taglib-1.3.5.jar, folder META-INF/tld/. And I don't need to set anything in web.xml <tag-lib> tab anymore.
          All the jsp pages can be successfully compiled while being deployed to Server. So what am I missing? My build.xml file looks like:
               <target name="compile-jsp">
                    <wlappc source="${src.dir}" output="${out.dir}"
                         keepgenerated="true" optimize="true" classpathref="wl_classpath"/>
               </target>
          where "wl_classpath" contains all the struts related jar files, e.g. struts-core-1.3.5.jar, struts-taglib-1.3.5.jar, ...., and weblogic related jars, e.g. weblogic.jar.....
          I checked "beehive" samples coming with weblogic92, and found it pretty much did the same thing regarding build script and jsp files. So I am totally lost!
          Please help me out. Many thanks.
          Edited by jqian at 02/02/2007 10:24 AM

Yes sorry, you're correct. The uri I mentioned is just 1.0.
Do you have the "Oracle WebLogic Web App Extension" Facet for your web project? If not, try adding that and making sure that there is a weblogic.xml file created in the WEB-INF dir. The weblogic.xml file allows you to deploy usig a shared lib for JSTL. It should contain a library-ref element something like the following, with a version of 1.1.
<wls:library-ref>
<wls:library-name>jstl</wls:library-name>
<wls:specification-version>1.1</wls:specification-version>
<wls:exact-match>true</wls:exact-match>
</wls:library-ref>

SQL in JSP - do I use JAVA code in % ... % or SQL Tag Library ??

I have a small web app that makes needs to make about 12 SQL queries in a JSP and am trying to figure out what is the best way to do this
I had initially coded this using plain JAVA code in the JSP as follows :-
<%
Connection conn = null;
Statement st = null;
ResultSet rs = null;
try {
st = conn.createStatement();
rs = st.executeQuery("select .........");
%>
But then I came across the SQL Tag Library in an article and wonder if this is more efficient code?
If so does anyone have a pointer to a good intro to these tags as they look complicated (I only am doing queries on the SQL database, no inserts or updates)

Sometimes you've gotta do what you've gotta do.
My rule is "no scriptlets".
If you MUST access a database from a JSP, the only right way to do it is to use JSTL <sql> tags.

Best way to call EJB - Servlet or Tag Library

Hi,
What is the best way to call an EJB from a JSP? We are using Weblogic 7.0(moving to 8.1 beta). WE have a form on a JSP that needs to get data from an EJB. Our flow goes from JSP --> Controller servlet or tag library -->EJB "Bean" Controller ---> EJB. The specfic EJB we need to populate drop downs and fields will be called by a bean controller. Is it better to call the bean controller using a tag library in the jsp or go to the controller servlet to get the data? If servlet is the answer, where do I lookup the EJB Home and call the create from within the servlet? Any help would be greatly appreciated!!
Thanks!

IMO, if you are following some design patterns, like the MVC framework, the best thing is to populate the model(entities that contain the business data) and call the respective getXX methods from the model on the JSP page. The reason for doing so is to keep JSP pages away from any other work other than to just display the business data contained in the respective business entities.
The model can be populated in the servlet and either set in the request or session attribute as per the requirement.
The EJB can be looked up in the servlet as and when required. I would suggest to make use of the Service Locator Pattern to do a look up for the EJB Remote Interface and accordingly make the business calls.
Hopefully this answers some of your questions.

My app can't see the tag library

Hi everybody,
I am developing an application in JSP which accesses an Oracle database and display the results to the user.
I am using the tag "exceltag.jar" taken from "http://www.servletsuite.com/servlets/exceltag.htm" to convert an html table to an excel sheet. This works fine on my computer but it fails after we installed the application to our web server, running Tomcat 4.1.12.
The "exceltag.jar" file has been placed under 'WEB-INF\lib' and the classpath has been set to point to that location. However when I attempt to convert the html table to an excel sheet by clicking a button, I get the following error:
java.lang.NoClassDefFoundError:
javax/servlet/jsp/tagext/BodyTagSupport at java.lang.ClassLoader.defineClass0(Native Method) at
java.lang.ClassLoader.defineClass(ClassLoader.java:509)
It seems like the application can't see the "exceltag.jar" file.
What do I need to do to overcome this problem?
Thank you very much.

The servlet.jar is in TOMCAT_HOME/common/lib. Since all the JARs in that directory are automatically added to the CLASSPATH and are visible to all applications running under Tomcat, you don't have to do anything for the class loader to find it.
Your app's WEB-INF/lib directory JARs are also automatically added to to the CLASSPATH. That's the correct place to put that exceltag.jar, by the way, not the TOMCAT_HOME/common/lib.
As a matter of fact, if you have a system CLASSPATH, be sure that Tomcat ignores it completely. You shouldn't even have one, IMO. (I don't.)
When I open up the servlet.jar in my TOMCAT_H0ME/common/lib, I can see a class named BodyTagSupport with path javax.servlet.jsp.tagext. You should, too.
In your exceltag.jar, you should find a TLD for the library. Open that with a text editor and make sure that the text under the <uri> tag matches that in your JSP. For example, I use the JSTL tag library. The c.tld has this <uri> tag:
<uri>http://java.sun.com/jstl/core</uri>My JSPs that want to use the core tag library have this near the top of the page:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>Notice how the URIs match. That's what yours should do, too.
If you don't find a TLD inside the exceltag.jar, that means they didn't package it properly. - MOD

No tag library
