Modifying web.xml for a custom tag

Hello all, I'm trying to create a custom tag, and I'm having trouble trying to understand some elements of web.xml. Can someone tell me in detail what <taglib-uri> is? I know <taglib-location> is the directory where the .tld file is stored.
Also, is there anywhere online where I could find out more about the different compinents of web.xml? (I can't find any good websites).
Thanks a lot.

<taglib>
<taglib-uri>/mytags</taglib-uri>
<taglib-location>/mytags.tld</taglib-location>
</taglib>That means that your tag libaray definition is located at /root/mytags.tld. Some people put them in the WEB-INF, which would make it /root/WEB-INF/mytags.tld.
The taglib-uri is how you are going to reference it in your JSP. With the above setup, here is how you would reference in your JSP
<%@ taglib uri="/mytags" prefix="myTagPrefix" %>
<myTagPrefix:mySpecialTag/>
Hope this helps.

Configuing web.xml for using JSTL tags in WAS

Hi All
I have an application deployed in websphere.
After extracting jakarta-taglibs-standard-current.zip I copied the jar files ( from the \jakarta-taglibs-standard-1.0.6\lib folder) to the web-inf\lib folder.
Then I saved the c.tld ( from the jakarta-taglibs-standard-1.0.6\tld folder) to the \web-inf\taglibs\ folder
Then I modified the web.xml to include
       <taglib>
             <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
             <taglib-location>/WEB-INF/tlds/c.tld</taglib-location>
      </taglib>The problem is when i restart the application from the WAS administrative console. The application does not restart with the error
Exception:
com.ibm.ejs.sm.exception.ActiveObjectException--------
com.ibm.ejs.sm.client.command.ExecutionException: Command HostPubServer.start Sub-command Error.     at com.ibm.ejs.sm.client.command.AbstractCommand.handleAct(AbstractCommand.java:288)

     at com.ibm.ejs.sm.client.command.ThreadPool$PooledThread.run(ThreadPool.java:89)
When I remove the " <taglib-location>/WEB-INF/tlds/c.tld</taglib-location> " I am able to restart the application. But the path is right.. and the tld is ther. What cud be the issue here ??
Any thoughts ??
Thanks

Hi
The position of the tablig tag in web.xml was wrong. So it was not validated according to the dtd specification. I placed the tag after the errortag in the web.xml and it resolved the issue.

How to create a simple web.xml for using servlets

Hello i wanna configure the web.xml that i can use sevlets and beans, but how can i do that?
This is de directorie i have installed my webapp
C:\Tomcat 4.1\webapps\testapp
C:\Tomcat 4.1\webapps\test\WEB-INF\classes (in this dir, I wanna put my beans and servlets, I got one servlet and the name is LogIn.class).
And i wanna request my servlets with the url http://localhost:8080/testapp/servlet/LogIn
How can i create a very basic web.xml with working beans, servlets and session? It is for testing-use only, so the security is not important for me at this moment.
Tnx

under your web-inf
in your web.xml file you must map
the servlets
under the <web-app> tag type
<servlet>
     <servlet-name>LogIn</servlet-name>
     <servlet-class>com.LogIn</servlet-class>
</servlet>
<servlet-mapping>
      <servlet-name>LogIn</servlet-name>
      <url-pattern>/LogIn</url-pattern>
</servlet-mapping>ps: start using some IDE such as NetBeans or Ecclipse
since they will take care of mapping all servlets and Beans
and generate all the necessary files for your web-app

Do we need to put the following code in the web-xml for the project to run

Hi^^^,
actually I have created a project in Eclipse WTP and I am running it from remote server. Its giving me 404 error when I tried to run it.
I know 404 error is generally due to some error in deployment descriptor.
I am going through this tutorial for creating project in eclipse WTP
this says that I need to include the following code in web-xml. Please look at the quotes below
"Web modules in J2EE has a deployment descriptor where you configure the web application and its components. This deployment descriptors is called the web.xml. According to the J2EE specification, it must be located in the WEB-INF folder. web.xml must have definitions for the Servlet and the Servlet URI mapping. Enter the following lines into web.xml:"
"Listing 2. Deployment Descriptor web.xml"
<servlet>
<servlet-name>Snoop Servlet</servlet-name>
<servlet-class>org.eclipse.wtp.tutorial.SnoopServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Snoop Servlet</servlet-name>
<url-pattern>/snoop/*</url-pattern>
</servlet-mapping>
My question is, it is necessary to include the above lines between <servlet> and </servlet-mapping> in web-xml
thanks and regards,
Prashant

I know 404 error is generally due to some error in deployment descriptor. what's the url you've put.
<servlet>
<servlet-name>Snoop Servlet</servlet-name>
<servlet-class>org.eclipse.wtp.tutorial.SnoopServlet</servlet-class>
</servlet> Every Servlet has to have a <servlet></Servlet> tag in the web.xml
the <servlet-name>is for the naming the servlet and the <servlet-calss>is for class file of the servlet in your case the .class file is to be in the package of tutorial,if it's not then how the container will no where the calss file is
<servlet-mapping>
<servlet-name>Snoop Servlet</servlet-name>
<url-pattern>/snoop/*</url-pattern>
</servlet-mapping>You type something in your url likk http://localhost:8080/webappname (Tomcat server),so for url mapping instead of typing the entire class file name ,you just enough have to type what you've put in the <url-mapping> tag and it has to be inside of <servlet-mapping>
I think the problem is in <url-pattern> change it like /snoop<url-pattern>
My question is, it is necessary to include the above lines between <servlet> and ></servlet->mapping> in web.xmlSo now you think whether you need something inside <servlet>and </servlet-mapping>

Where does the jar for a custom tag libary need to go?

I am having trouble getting a custom tag library's classes found. These are located
in a jar file called blazix.jar.
I have the following GetName.jsp:
<%@ taglib prefix="blx" uri="/blx.tld" %>
<jsp:directive.page import="com.company.project.ejb.UserData"/>
<jsp:useBean id="user" class="UserData" scope="session"/>
<HTML>
     <BODY>
          <blx:getProperty name="user" property="*">
          <FORM METHOD=POST ACTION="SaveName.jsp">
               What's your name? <INPUT TYPE=TEXT NAME=username SIZE=20><BR>
               What's your e-mail address? <INPUT TYPE=TEXT NAME=email SIZE=20><BR>
               What's your age? <INPUT TYPE=TEXT NAME=age SIZE=4>
               <P><INPUT TYPE=SUBMIT>
          </FORM>
          </blx:getProperty>
     </BODY>
</HTML>
When I run this, I get the following:
Parsing of JSP File '/GetName.jsp' failed:
/GetName.jsp(1): Error in using tag library uri='/blx.tld' prefix='blx': cannot
find tag class: 'desisoft.jsp.tagext.SetProp'
probably occurred due to an error in /GetName.jsp line 1:
<%@ taglib prefix="blx" uri="/blx.tld" %>
The jar does contain the needed class (desisoft.jsp.tagext.SetProp), but how can
I tell WebLogic where to find it?
In other words, what directory does the blazix.jar need to go under? I tried
adding it to my classpath but that did not help.
Thanks!

I got it. Just needed to add my own lib directory under WEB-INF and copy the jar
to it.
Question though, why wouldn't this get generated for me? Would think it would
be a common thing to need.

I placed the blx.tld file under the WEB-INF directory. It seems to find

Dynamically modifying web.xml

Hi,
          I am trying to write code that will dynamically add a servlet definition to a deployed application. ie, the deployment descriptor is dynamically edited. In Tomcat, I am able to edit the web.xml file(when the app is exploded) or I can edit the in memory copy and produce a servlet definition on the fly
          I am trying to do the same of Weblogic 8.1. Everything is straightforward as long as the app is exploded, in which case I simply edit the web.xml file..when the app is not exploded, this is not possible. I tried using MBeans to see if I can add a servletRuntimeMBean to a deployed application, but this does not seem possible..looks like these beans are instantiated by the container and there is no handle for developers to create instances of these beans. I was wondering if it was possible to edit the in memory copy of web.xml that the servlet container records. Any suggestions in this regard would be highly welcome
          Thanks, and sorry for the lengthy email!
          Ram

Eclipse editor gives error for web.xml for jsp-config

Hi All,
I am using following web.xml . Eclipse europa editor gives warning if <jsp-config> is added. Is anyone have idea about it.
<?xml version="1.0" encoding="ISO-8859-1"?>

Your web.xml file is out of date.
You have a DTD there for the Servlet 2.2 spec.
The jsp-config tag was introduced to web.xml as of the Servlet 2.4 specification - which is why it is complaining in your editor.
Seeing as you have Tomcat 6, I would recommend you change your web.xml to look like this
- removed the DTD
- change the web-app tag to include schema information
<?xml version="1.0" encoding="ISO-8859-1"?>

Example web.xml for JSTL?

I need to find an example web.xml file that shows where thet tablib statements for JSTL go and what they look like in a web.xml file. I was looking at an article I found through Google that pointed to Javasoft doc on this subject but the link didn't work, and anyway, I prefer examples to specifications. I haven't found a good example yet. Can someone point me to one or post one? I need both contents of the taglib statements and a clear picture of exactly where in the web.xml file they go. I think the statements are:
<taglib>
    <taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
    <taglib-location>/WEB-INF/fmt.tld</taglib-location>
</taglib>
<taglib>
    <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
    <taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>
<taglib>
    <taglib-uri>http://java.sun.com/jstl/sql</taglib-uri>
    <taglib-location>/WEB-INF/sql.tld</taglib-location>
</taglib>
<taglib>
    <taglib-uri>http://java.sun.com/jstl/x</taglib-uri>
    <taglib-location>/WEB-INF/x.tld</taglib-location>
</taglib>Thanks.
Ken

Just to confirm
- what server/version are you deploying on where it doesn't work?
- what server do you have that it does work on? Is it the same?
- you have both standard.jar and jstl.jar? Check the version by opening with a zip tool and looking at the manifest.mf file.
- what URI are you using to import the tag libraries with?
To install JSTL, all you need is jstl.jar and standard.jar, in a place where the webapp can find them.
Most commonly is the WEB-INF/lib directory
Most servers also have a "shared" directory idea - eg tomcat has the /common/lib and /shared/lib directories. The JSTL jars will work just as well in those directories.

Need server.xml and web.xml for connection pooling

hi guys,
I am having lots of problem implementing the Connection Pool. I want to use the Tomcat's Connection pool classes and not my connection pool.
I have gone through lots of problem trying to configure it.
I got the range of errors. Has someone worked on this. Does it work with Tomcat 4.1 and Oracle 8i. Can anyone provide any links or previous posts to help me out.
If someone can paste their working server.xml and web.xml then that would be really grt.
Any kind of help would be really helpful.
Amit

Tomcat does not have a connection pooling mechanism. I've used Apache Commons DBCP with Tomcat although with PostgreSQL. It works great.
Nothing in my web.xml gets modified. Only server.xml needs to be updated for DBCP. The Tomcat JNDI Datasource documentation is very good and should get you through.

when we drag-and-drop custom tag control in the source of jsp page, when we switch to the design view of jsp we should be able to view controls as desired.
Observation: 1) Eclipse 3.2 doesn't have design view for jsp pages.
2) which software uses the design view. we need to extend eclipse core framework and we do not find any technical approach document to proceed further on this.
3) RAD 6.0 we can see a JSP in design view.
I'm searching for any technical approach document to create plugin that can intercept the custom tags and provide a design view.
Will any one suggest the plugin for that.

Jeff,
I have checked with engineering and found that JSP Design View support on
Linux is a planned feature for the next release. I don't think we will have
this feature as part of a Service Pack for 8.1

Jess,
Unfortunately, the JSP design view is currently not supported on Linux.
Workshop does allow to do remote development where the IDE is running
on a
Windows machine and connects to a server running on Linux/Solaris.

Does anybody else who is running the Linux version of Workshop 8.1have
troubling
getting the Design View of JSP files to come up. All I see is thesource,
with
no tabs at the bottom to switch to/from the Design View. When I bootover
to
Windows and run 8.1 Workshop, I see both tabs and I am able to useboth
views.
Is it something I have set in Preferences somewhere that disablesthe
Design
View ???
Thanks,

Can I write Design-time for JSP custom tag(not JSF components)

I have some old JSP custom tags(not JSF components), and I want to use them in the IDE through the toolbox.
Now I have already written the BeanInfos for these tags, and they can be drag from the toolbox; but it will throw a Exception when render the tags, and the properties in the Property Editor are not which I describe in the BeanInfos.
How can I write Design-time for these tags? or whether it is possible to write the Design-time for these tags?
the Exception is shown as follow:
java.lang.ClassCastException

How to add a reference to help for a custom tag

Hello,
I would like to add an icon (question mark icon) to my custom tag (in tag libraries view). Then, when I press this icon I would like to see some .html page with description of a tag as it is done for a struts tags.
Is it possible?
If yes please tell me how to do it.
Thanks,
Damian

There are a variety of customization options available for BEA Workshop. Through metadata you can define renderings for custom tags, tag appearance in the tag libraries view, customize the tag editors, and much more.
Information about customization can be found at the following link: http://workshopstudio.bea.com/docs/tlei.htm
Adding custom tag documention to the Tag Libraries view is not currently a configuration option but would be a useful addition. I will file an enchancement request for this functionality.
