<s:decorate>

<div class=”prop”>

<s:label id=”editLabel” styleClass=”#{invalid?’errors’:”}”>

<span id=”editSpan” class=”#{invalid?’errors’:”}”>

<ice:inputText id=”createdById” requiredMessage=”This field value is required.” partialSubmit=”true” required=”true” size=”100″ maxlength=”130″ value=”#{featureSetHome.instance.createdBy}”>

1. With just <s:decorate>, required=”true”, s:message and without requiredMessage attribute.
   

   <s:decorate>
   

   <div class=”prop”>
   

   <s:label id=”editLabel” styleClass=”#{invalid?’errors’:”}”>
   

     created by
   

     <s:span styleClass=”required” rendered=”true”>*</s:span>
   

     </s:label>
   

   <span id=”editSpan” class=”#{invalid?’errors’:”}”>
   

     invalid value > #{invalid}
   

   <ice:inputText id=”createdById” partialSubmit=”true” required=”true” size=”100″ maxlength=”130″ value=”#{featureSetHome.instance.createdBy}”>
   

     </ice:inputText>
   

     </span>
   

     <s:message styleClass=”error errors” />
   

     </div>
   

     </s:decorate>
   

1. This code work fine.
   

programList.setOrder(“program.programName asc, program.programId desc”);

1. The below code snippet won’t work –
   
   1. programList.setOrderColumn(“program.programName asc, program.programId desc“);
      
   2. programList.setOrderColumn(“program.programName asc);
      

       

      It throws the following exceptions – Caused by java.lang.IllegalArgumentException with message: “invalid order column (“program.programName asc, program.programId desc” must match the regular expression “^\w+(\.\w+)*$”)”
      

       

   3. This works fine – programList.setOrderColumn(“program.programName”);
      1. But we have to set

         customerList.setOrderDirection(“asc”); or customerList.setOrderDirection(“desc”);

    

    

Some customers want to internationalization and customize error messages to display in end-user browser, whenever some error occurred in the server side. Ex: Tomcat server is down; some server resources are not available etc.

This document talks about customize error message and internationalize error messages–

The version I used is –

1.    Apache2.2

Please follow the following step to configure successfully…

1)   Customize error message –

a.     Open “httpd.conf” from “C:\Program Files\Apache Software Foundation\Apache2.2\conf”and search for “ErrorDocument” word in the doc.

b.    You can find something like –

# Customizable error responses come in three flavors:

# 1) plain text 2) local redirects 3) external redirects

#

# Some examples:

#ErrorDocument 500 “The server made a boo boo.”

#ErrorDocument 404 /missing.html

#ErrorDocument 404 “/cgi-bin/missing_handler.pl”

c.     Just uncomment whatever error code message you would like to display.

Ex:

ErrorDocument 404 /missing.html

d.    Syntax:ErrorDocument error-code document

e.    Create the file (missing.html) in the following path “C:\Program Files\Apache Software Foundation\Apache2.2\htdocs”

f.      Whenever you have got 404 error code – missing.html would display.

2)   Internationalize error messages

a.     Open “httpd.conf” from “C:\Program Files\Apache Software Foundation\Apache2.2\conf”and search for “ErrorDocument” word in the doc.

b.    You can find something like-

 # Customizable error responses come in three flavors:

c.     And above  to this line add the following code in “httpd.conf” –

Alias /error/ “C:/Program Files/Apache Software Foundation/Apache2.2/error/”

<Directory “C:/Program Files/Apache Software Foundation/Apache2.2/error”>

            AllowOverride None

            Options IncludesNoExec

            AddOutputFilter Includes html

            AddHandler type-map var

            Order allow,deny

            Allow from all

            LanguagePriority en cs de es fr it nl sv pt-br ro

            ForceLanguagePriority Prefer Fallback

</Directory>

ErrorDocument 503  /error/HTTP_SERVICE_UNAVAILABLE.html.var

d.    So finally, it would appear like this –

Alias /error/ “C:/Program Files/Apache Software Foundation/Apache2.2/error/”

<Directory “C:/Program Files/Apache Software Foundation/Apache2.2/error”>

            AllowOverride None

            Options IncludesNoExec

            AddOutputFilter Includes html

            AddHandler type-map var

            Order allow,deny

            Allow from all

            LanguagePriority en cs de es fr it nl sv pt-br ro

            ForceLanguagePriority Prefer Fallback

</Directory>

#

# Customizable error responses come in three flavors:

# 1) plain text 2) local redirects 3) external redirects

#

# Some examples:

#ErrorDocument 500 “The server made a boo boo.”

#ErrorDocument 404 /missing.html

ErrorDocument 503  /error/HTTP_SERVICE_UNAVAILABLE.html.var

#ErrorDocument 503 /missing.html

#ErrorDocument 404 “/cgi-bin/missing_handler.pl”

e.    If you to customize the error message displayed from “HTTP_SERVICE_UNAVAILABLE.html.var”

                                          i.    You can open the “HTTP_SERVICE_UNAVAILABLE.html.var” file in some text editor

                                         ii.    And change the message under appropriate language  type-

Ex:  “Content-language: en”
