Hi again, So far I've been unable to fix the problem from my previous posting below, but that can wait until I've sorted out a more serious and important issue which involves using JavaServer Faces to upload files.? I'm well aware that the form enctype has to be set to "multipart/form-data", and as JSF does not support file uploads directly, code has to be modified and extra jar files included.
I used the instructions and code downloaded from http://www.onjava.com/pub/a/onjava/2005/07/13/jsfupload.html in? an attempt to get this to work, after making a number of changes.? I took the code for "MyBean.java" and? the only change I made was to change the first line to "package com.onjava;" then put it in the path? "<my-root>/src/java/com/onjava" rather than in the path given in the example to simpify things a bit. Likewise I put the jsp files as provided in the in the path "<my-root>/web" omitting "/jsfupload" and added a plain "index.html" file which loads first then immideately redirects to "index.jsp". So far so good,? in "<my-root>/web/WEB-INF" I modified the xml files for JSF 1.2 and have the following code for "web.xml": <?xml version="1.0"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee"; ??????? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; ??????? xsi:schemaLocation="http://java.sun.com/xml/ns/javaee ??????? http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; ??????? version="2.5"> ??? <context-param> ??????? <param-name>javax.faces.STATE_SAVING_METHOD</param-name> ??????? <param-value>client</param-value> ??? </context-param> ??? <servlet> ??????? <servlet-name>FacesServlet</servlet-name> ??????? <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> ??????? <load-on-startup>1</load-on-startup> ??? </servlet> ??? <servlet-mapping> ??????? <servlet-name>FacesServlet</servlet-name> ??????? <url-pattern>/faces/*</url-pattern> ??? </servlet-mapping> ??? <servlet-mapping> ??????? <servlet-name>FacesServlet</servlet-name> ??????? <url-pattern>*.faces</url-pattern> ??? </servlet-mapping> ??? <filter> ??????? <filter-name>ExtensionsFilter</filter-name> ??????? <filter-class>org.apache.myfaces.component.html.util.ExtensionsFilter</filter-class> ??????? <init-param> ??????????? <param-name>uploadMaxFileSize</param-name> ??????????? <param-value>10m</param-value> ??????? </init-param> ??????? <init-param> ??????????? <param-name>uploadThresholdSize</param-name> ??????????? <param-value>100k</param-value> ??????? </init-param> ??? </filter> ??? <filter-mapping> ??????? <filter-name>ExtensionsFilter</filter-name> ??????? <servlet-name>FacesServlet</servlet-name> ??? </filter-mapping> ??? <welcome-file-list> ??????? <welcome-file>/index.html</welcome-file> ??? </welcome-file-list> </web-app> and for "faces.config.xml" have the following code: <?xml version="1.0"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee"; ??????? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; ??????? xsi:schemaLocation="http://java.sun.com/xml/ns/javaee ??????? http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd"; ??????? version="1.2"> ??? <managed-bean> ??????? <managed-bean-name>myBean</managed-bean-name> ??????? <managed-bean-class>com.onjava.MyBean</managed-bean-class> ??????? <managed-bean-scope>request</managed-bean-scope> ??? </managed-bean> ??? <navigation-rule> ??????? <from-view-id>/MyForm.jsp</from-view-id> ??????? <navigation-case> ??????????? <from-outcome>OK</from-outcome> ??????????? <to-view-id>/MyResult.jsp</to-view-id> ??????? </navigation-case> ??? </navigation-rule> </faces-config> Then in order to compile "MyBean" I had to include in "<my-root>/web/WEB-INF/lib" the following jar files: commons-fileupload-1.1.jar commons-io-1.2.jar jsf-api.jar jsf-impl.jar tomahawk-1.1.6.jar The last one I had a bit of difficulty finding, but it seems to have the correct code.? Anyway, I managed to compile the code successfully and the compiler created a class file in "<my-root>/web/WEB-INF/classes/com/onjava".? However, on creating a war file and deploying it I get in my browser the error message "HTTP Status 503 - ... The requested service () is not currently available", and in the log I get the message: Exception sending context initialized event to listener instance of class com.sun.faces.config.ConfigureListener java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at org.apache.myfaces.renderkit.html.util.ExtensionsPhaseListener.<clinit>(ExtensionsPhaseListener.java:49) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) blah blah blah..... etc. I would most appreciate some kind help in getting this sorted out.? There must be some people around who know how to write a simple file upload utility with JSF.? Incidentally, I wish I could go to that conference in Phoenix, but I'm here working on my own in isolation in France until I return to Tucson at the end of September.

Before leaving Tucson I got the book "A Complete Reference: JavaServer Faces" by C.Schalk and E.Burns in addition to some other books I brought with me, and I'm having trouble understanding the correct use of the tag <h:message for "myName"/> where id="myName" refers to something like <h:inputText value="#{UserBean.someName}" required="true"? id="myName"/> in a form.? In the example in the book if the input field is left blank, the message to the right of the input field "Validation Error: Validation is required." is displayed, but when I actually try the example I get to the left the error message the default id provided by JSF followed by a ":" followed by say "myName" printed as a literal.? If I give the form an id such as "myForm" then the message "myForm:myName" appears to the left of the validation error message.? That is an improvement but I still want to know why it appears, rather than not as given in the book, or alternatively provide a better message.? Likewise with the example at http://exadel.com/tutorial/jsf/jsftags-guide.html where the? id is not displayed in the error message. I checked that I had jsf-impl.jar and jsf-api.jar in the classpath, and in fact looking at the contents of the former I found in "Message.properties" the entry "javax.faces.component.UIInput.REQUIRED={0}: Validation Error: Value is required.", but for some reason it's displaying the id as a literal. Some advice on this would be most appreciated.? I will be back in Tucson at the very end of September, and hope by then that I will learn much more about JSF, as I'm putting them to use here.
