<html:html locale="true">

Oh, it's referring to that locale att.

Carry on.

I should mention that I'm a total noob, and this is my first
struts endeavor.

I am using Tomcat 5 which I know works.

Here is web.xml
<?xml version="1.0" encoding="ISO-8859-1"?> <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee <a href="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"" target="_blank" rel="nofollow">http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"</a> version="2.4"> <welcome-file-list> <welcome-file> FileUpload.jsp </welcome-file> </welcome-file-list> <!-- <servlet> <servlet-name></servlet-name> <servlet-class></servlet-class> </servlet> <servlet-mapping> <servlet-name></servlet-name> <url-pattern></url-pattern> </servlet-mapping> --> <servlet> <servlet-name>action</servlet-name> <servlet-class> org.apache.struts.action.ActionServlet </servlet-class> <init-param> <param-name>config</param-name> <param-value> /WEB-INF/struts-config.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> </web-app>

and struts-config.xml looks like ...
<?xml version="1.0" encoding="ISO-8859-1" ?> <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.0//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd"> <struts-config> <!-- ========== Form Bean Definitions ============ --> <form-bean name="FileUpload" type="roseindia.net.StrutsUploadForm"/> <!-- ========== Global Forward Definitions ========= <global-forwards> </global-forwards>--> <!-- ========== Action Mapping Definitions ======== --> <action-mappings> <action path="/FileUpload" type="roseindia.net.StrutsUploadAction" name="FileUpload" scope="request" validate="true" input="/pages/FileUpload.jsp"> <forward name="success" path="/pages/uploadsuccess.jsp"/> </action> </action-mappings> </struts-config>

I am trying the upload-file example at

But, I have this line ...
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>

... in a .jsp, with the struts-taglib-1.3.5.jar in /WEB-INF/lib,
and I get the following error when I load the .jsp.

I didn't get to dynamic att's yet, Chandu.

Did you read Bryan Basham's tutorial?:

https://coderanch.com/t/170429/java-Web-Component-SCWCD/certification/Tutorial-Dynamic-Attributes

Well, this works . . .

<%@ taglib prefix="myTags" uri="simpleTags" %> <%@ page import="java.util.ArrayList" %> <%-- <jsp:useBean id="movie1" class="foo.Movie"> <jsp:setProperty name="movie1" property="name" value="Crawlspace" /> <jsp:setProperty name="movie1" property="genre" value="Horror" /> </jsp:useBean> <jsp:useBean id="movie2" class="foo.Movie"> <jsp:setProperty name="movie2" property="name" value="Blind Swordsman" /> <jsp:setProperty name="movie2" property="genre" value="Samurai" /> </jsp:useBean> --%> <% java.util.ArrayList movieCollection = new java.util.ArrayList(2); foo.Movie m1=new foo.Movie(); foo.Movie m2 = new foo.Movie(); m1.setName("Seven Days In May"); m1.setGenre("Drama"); m2.setName("The High and the Mighty"); m2.setGenre("Airplane"); movieCollection.add(m1); movieCollection.add(m2); request.setAttribute("movieCollection", movieCollection); %> <HTML> <BODY> <table> <myTags:movieTag movieList="${movieCollection}"> <tr> <td>${movie.name}</td> <td>${movie.genre}</td> </tr> </myTags:movieTag> </table> </BODY> </HTML>

Thanks for the tip Marc.
No telling when it would have occured to me to give the thing a scope.

I am trying to get the "Simple tag with attribute" example on page 511 of HFSJ working.

Here's the code . . .
<%--this is the jsp--%> <%@ taglib prefix="myTags" uri="simpleTags" %> <%@ page import="java.util.ArrayList" %> <jsp:useBean id="movie1" class="foo.Movie"> <jsp:setProperty name="movie1" property="name" value="Crawlspace" /> <jsp:setProperty name="movie1" property="genre" value="Horror" /> </jsp:useBean> <jsp:useBean id="movie2" class="foo.Movie"> <jsp:setProperty name="movie2" property="name" value="Blind Swordsman" /> <jsp:setProperty name="movie2" property="genre" value="Samurai" /> </jsp:useBean> <% java.util.ArrayList movieCollection = new java.util.ArrayList(2); movieCollection.add("${movie1}"); movieCollection.add("${movie2}"); %> <HTML> <BODY> <table> <myTags:movieTag movieList="${movieCollection}"> <tr> <td>${movie.name}</td> <td>${movie.genre}</td> </tr> </myTags:movieTag> </table> </BODY> </HTML> ********************************************************* //Heres the .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>1.2</tlib-version> <jspversion>2.0</jspversion> <uri>simpleTags</uri> <tag> <description> to print movieList</description> <name>movieTag</name> <tag-class>foo.MovieTag</tag-class> <body-content>scriptless</body-content> <attribute> <name>movieList</name> <required>true</required> <rtexprvalue>true</rtexprvalue> </attribute> </tag> </taglib> ********************************************************** //and here's the tag handler class . . . package foo; import javax.servlet.jsp.JspException; import javax.servlet.jsp.tagext.SimpleTagSupport; import java.io.IOException; import java.util.ArrayList; import java.util.Iterator; public class MovieTag extends SimpleTagSupport{ private ArrayList movieList; public void setMovieList(ArrayList movieList){ this.movieList=movieList; }//setMovieList public void doTag() throws JspException, IOException{ Iterator i = movieList.iterator(); while(i.hasNext()){ Movie movie = (Movie) i.next(); getJspContext().setAttribute("movie", movie); getJspBody().invoke(null); }//while }//doTag }//MovieTag ************************************************************** //and here's the bean. package foo; public class Movie{ private String name; private String genre; public void setName(String name){ this.name=name; }//setName public String getName(){ return this.name; }//getName public void setGenre(String genre){ this.genre=genre; }//setGenre public String getGenre(){ return this.genre; }//getGenre }

The tag handler class and the bean are in $CATALINA_HOME/webapps/simple_tag/WEB-INF/classes/foo.

The .tld is in /WEB-INF.

When I run it, in Tomcat 5.5.12, I get a NullPointer exception at the line where the iterator is declared in the tag handler.

Any thoughts will be greatly appreciated.

Thank you,

A java bean should always have a zer0-arg constructor.

Try the core_rt tag library.

I have the Person/Employee example from HFSJ
working with no page directive and nothing
in the DD with Tomcat 5.5.12.

I was getting that error.
I think I have solved my problem.
I used c-rt.tld in standard.jar,and it worked.
That must be why they say to use c-rt.tld instead of c.tld.

Does anyone know why this code ...
<%@ page isELIgnored="false"%> <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %> <HTML><BODY> <% String [] movieList = {"Brokeback", "Female Trouble", "The Hidden"}; pageContext.setAttribute("movieList", movieList); %> <table> <c:forEach var="movie" items="${movieList}"> <tr> <td>${movie}</td> </tr> </c:forEach> </table> </BODY></HTML>

produces this result ...

[Ljava.lang.String;@1629e71

Thank you.

The icon with the pencil image, Change Driver? It's the same function
as the right-click->Change Driver function from the last post.
Does not work.

I am trying DBExplorer, with as much success.

I am using Eclipse 3.1 with MySQL 4.1 on Fedora 4 os. Anyone on a
similar system have success Eclipse and MySQL?

I am trying to hook MySQL up to Eclipse.

While I am overall very pleased with the Eclipse IDE, I cannot
install the driver for MySQL in the way in which I think I
am supposed to be able to.

First, I installed Eclipse 3.1.1 by untar.gz'ing it in /usr/local.
Eclipse works right out of the box.

Then, I downloaded SQLExplorer from sourceforge. I unzipped it in
the Eclipse folder--this is the 2.2.3 version (the 2.2.4 doesn't seem to work)--I am then able to get an SQLExplorer Perspective.

I think I am supposed to be able right click on MMMySQL Driver in the
Driver View and get a window that allows me to change drivers.
I want to change it to the MySQL connector .jar that the SQLExplorer
instructions tell you to download, which languishes in /root/Desktop/mysql-connector, but when I right-click MMMySQL Driver nothing happens.

One counterexample:
public static void main(String [] fred){ System.out.print((-7)>>>0); }

You are correct (as far as the anonymous not being implicitly abstract), because this code . . .
public abstract class AbstractTest { public abstract int getNum();// { //return 45; //} public abstract class Bar { public int getNum() { return 38; } } public static void main (String [] args) { AbstractTest t = new AbstractTest() { //public int getNum() { // return 22; //} }; AbstractTest.Bar f = t.new Bar() { public int getNum() { return 57; } }; System.out.println(f.getNum() + " " + t.getNum()); } }

produces this error . . .

*******************************
[user@computer java]# javac AbstractTest.java
AbstractTest.java:12: <anonymous AbstractTest$1> is not abstract and does not override abstract method getNum() in AbstractTest
AbstractTest t = new AbstractTest() {
