Problem deploying and using custom Tags in jar files

I am trying to create a custom tag library of Java classes, package them in a JAR file, and use them in another web application. Here is the JAR file structure, named mytags.jar:
META-INF
META-INF/manifest.mf
META-INF/taglib.tld
mytags/FooBar.class
mytags/Another.class
...Here is the taglib.tld file:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<taglib xmlns="http://java.sun.com/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-jsptaglibrary_2_0.xsd"
version="2.0">
   <tlib-version>1.0</tlib-version>
   <short-name>foo</short-name>
   <uri>fooTags</uri>
   <info>My tags</info>
   <tag>
     <name>fooBar</name>
     <tag-class>mytags.FooBar</tag-class>
     <body-content>empty</body-content>
     <attribute>
       <name>name</name>
       <required>false</required>
       <rtexprvalue>true</rtexprvalue>
     </attribute>
</tag>
</taglib>The FooBar class has getName(String) and setName() methods.
In the web application, I have copied mytags.jar into the WEB-INF/lib directory. I've verified that it lands in the corresponding directory for my appserver (I'm using Tomcat 6.0.10).
Here's the header for my JSP:
<%@ page language="java" contentType="text/html;charset=UTF-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib uri="fooTags" prefix="foo" %>
<foo:fooBar name="dummy" />
...When I access my page, the browser sits there and spins, not able to do anything. I know that some of the content is executed, but it is not able to get to the fooTags. I have tried replacing fooTags with WEB-INF/lib/mytags.jar, to no effect.
According to the docs, I should not need to include anything in web.xml to reference the fooTags. The tag library classes are valid, since I used them as local tags prior to moving them into a Jar library.
Any help would be appreciated

Take the code of the jsp file :
<%@ page language="java" %>
<%@ taglib uri="WEB-INF/struts-html.tld" prefix="html" %>
<html>
   <head>
     <title> First Struts Application </title>
   </head>
     <body>
        <table width="500" border="0" cellspacing="0" cellpadding="0">
        <tr>
          <td> </td>
        </tr>
        <tr bgcolor="#36566E">
          <td height="68" width="48%">
            <div align="left">
              <img src="images/hht.gif" width="220" height="74">
            </div>
          </td>
        </tr>
        <tr>
         <td> </td>
        </tr>
       </table>
       <html:form action="Lookup"
                  name="lookupForm"
                  type="wiley.LookupForm" >
       <table width="45%" border="0">
        <tr>
          <td>Symbol:</td>
          <td><html:text property="symbol" /> </td>
        </tr>
         <tr>
          <td colspan="2" align="center"><html:submit/> </td>
         </tr>
        </table>
      </html:form>
     </body>
</html>

Problem with JSP using bean packaged in jar file

Hi,
          I am trying to use a java bean in a jsp file. The java bean is packaged
          into a jar file. I am getting class not found compilation error. If the
          bean remains to be a seperated class file, everything work well.
          Does anyone know how I can use bean in a jar file within jsp , i.e. to
          allow the bean to be found during compilation ?
          Thanks,
          Terence.

Jacek,
          Thanks for replying.
          My JSP's are just files in my document root . However, I found a solution to
          my
          problem. That is to have the jar file defined in my weblogic.class.path. I may
          have missed some files in my original jar file which causes my problem.
          Mayby I should package everything into a web application for deployment. That
          will be my next step.
          Thanks anyway.
          Terence.

Dreamweaver cs4 or mx2004 may built .war or .jar files for deployment in a jsp server (Tomcat) ? If no, and use Dreamweaver how do these files ?

Dreamweaver cs4 or mx2004 may built .war or .jar files for deployment in a jsp server (Tomcat) ? If no, and use Dreamweaver how do these files ?

if I use Eclipse IDE for compilation[make *.war & *.jar files from *.java like claimBeans.java], I must use also Eclipse for upload/deploy ? Or for upload ONLY I may use and dreamweaver ? The jsp section of dreamweaver, is for app not require compilation, like from Code from:JSP STANDARD TAG LIBRARY , only ?
Basically whatever I may do with "JavaBeans", "Servlets" etc (*.java files) needed to get compiled, I may also do it with JSP STANDARD TAG LIBRARY etc NOT NEEDED Compilation, so if I do not understand how to compile&deploy *.war & *.jar files , I may use instead the latter way ?

Can i use Custom Tags for Database retrieval (as per MVC pattern)?

In our project we are dealing with database, and i've used the Cutom Tags for database retrieval (as per the Article from Mr Faisal Khan) and it is working fine. But i have a doubt if it affects the performance in any way . I wanted to know if its recommendable to use Custom Tags for the DB retrieval as per MVC Pattern or shall i create a intermediate bean and then call the bean in custom tag.
Thanks
Prakash

Putting database code in your JSPs certainly couples your view to the database. That's usually not good.
If it's a simple app, it might be justified.
When you start having lots of pages and complex business logic it becomes less attractive. - MOD

Can i make own formatted textbox using custom tag

Hai,
Can i create own format textbox similar to vb activex control.for example i want make own formatted textbox for enter only numeric value if entry any alpha value it's show error.Is this possible using custom tag

Hai,
Can i create own format textbox similar to vb
activex control.for example i want make own
formatted textbox for enter only numeric value if
entry any alpha value it's show error.Is this
possible using custom tag
If you mean a custom text box in a web page without an applet (in other words an html component), then Java has nothing to do with it. And by mentioning activex (even only in a 'like' comparison), and custom tag, you are once again hinting that you want an html component. I think you need to place your request to a JavaScript Forum, which, once again, has absolutely nothing to do with Java.
A "custom tag" in JSP is not an HTML Tag. It may look a little like an html or xml tag, but it is evaluated on the server side. The control you need must be executed on the client side, which, once again, tells me you need to post to a JavaScript forum.

How to use Stylesheets packaged in JAR file

Hi,
I would like to package XSL files in a JAR. The stylesheet may import other XSL files. For example:
<xsl:import href="demos.xsl">
<xsl:import href="table.xsl">
where the original stylesheet and the imported stylesheets (demos.xsl and table.xsl) are all located in this package: com.company.xsl
Is there a way for the transformers to retrieve the files from the JAR?
Possibly another complication is that this JAR file is loaded at runtime.
Any suggestions would be of great help. Thanks!

Thanks that worked.
However, is it possible to use a relative path? Right now it only works if the absolute path is used:
<xsl:import href="jar:file:///c:/applications/bin/myjar.jar!/com/company/xsl/table.xsl" />
It would be nice if this worked instead:
<xsl:import href="jar:file:///./bin/myjar.jar!/com/company/xsl/table.xsl" />

Using images stored in JAR files

I've got a small program which displays an image in a frame. I packaged all my classes and the picture into a jar file and made it executable. I can get the application to run but the picture doesn't show up.
Can i load the image whilst it is still in the jar file or do i have to extract it to use it? Please help...
Frendy

In your class you are loading an image correct? Here is some code to do it.
try
URL imageURL = getClass().getClassLoader().getResource( "image.gif" );
if ( imageURL != null )
Toolkit tk = Toolkit.getDefaultToolkit();
Image image = tk.createImage( ( ImageProducer ) imageURL.getContent() );
catch ( Exception e )

Simultaneous Client and Server Form Validation using Custom Tag Library

I am developing a custom tag library for validator tags
which are capable of doing client side validation (Javascript)
and server side (Java). My problem is with the development
of a regular expression based validator. Because of differences
in the way Javascript and Java handle regular expressions
i can not use the same regular expression for both types of
validation. Is there any way to convert a valid regular
expression from the java.util.regex format into the Javascript
format or vice versa? My major problems are with the (or, ||)
statements and the user of backslashes.

If you are speaking of RE syntax flavours, they are basically the same(namely perl5 flavour). Any expression that works in JS should work in j.u.regex too.
Though, their usage is quite different.
So, there is no need for convertion of expressions.
But porting the code may be not so trivial.

Problem using custom tag library in portlet's jsp

Hi,
I created a custom portlet (a JSR 168 portlet) and I'm using a tag library that I previously developed. Normally it works fine, but sometimes I get a ClassCastException. Once I redeploy the portlet everything works again. This is Oracle Portal 10.1.4.
Has anybody encountered similar problems?
Here's the exception:

How to use Custom Tags for Theme and Base Map Definitions

In Mapviewer documentation I've found the following new feature:
The XML definition of a theme or base map now supports application-specific
attribute tags. You can use the Custom Tags option in the theme definition in Map
Builder to specify tags and their values, which can be interpreted by your application
but are ignored by MapViewer itself.
I'm able to define a custom tag in Mapbuilder, but how can I use it in my Application?
Thanks.

As he said, you have to use as Platform service to create adapter in OIM.
tcUserOperationsIntf service = Platform.getService(Thor.API.Operations.tcUserOperationsIntf.class);
HashMap<String,String> searchmap=new HashMap<String,String>();
searchmap.put("Users.User ID", userID);
tcResultSet searchset=service.findAllUsers(searchmap);
