Struts - Nested Tags

I am using nested tags in Struts.
Is there a way to use nested tags with request scope ?
If you use nested tags with session scope it works (I can pass the value from the JSP to the Action ActionForward class using action) but if I use request scope, it does not work.
It gives the following message:

javax.servlet.ServletException: BeanUtils.populate
at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254)
at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:821)
at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254)
......

Does somebody know if is there a way to use request scope ???

Struts Internationalization

There is a file ApplicationResourses.properties that contains the key/value pairs for the default language of your application.
Is there a way to change from a comboBox (for example : English, Spanish , Portuguese) , the language of the application using cookie or something similar ??
For example, you choose your language from Spanish to English and the next time the user uses the aplication, the English language is loaded.

Struts - Using Nested Beans

For the code below, I want to list for each employee, the name , the email and the options of countries. I am using the following code to use the nested beans in Struts but the comboBox is not appearing. Does somebody know how I can insert a combo inside a nested bean ?? . The comboBox is supposed to load name of countries as shown below.....

<nested:iterate property="employees">
Employee: <nested:text property="empName"/>
E-mail: <nested:text property="email"/><br/>
Country :<html:select name="country" property="Name" indexed="true">
<html

ptions collection="country" property="value"/>
</html:select>
</nested:iterate>

Thanks,....

Struts - View html:select

Using struts I want to load a comboBox with a disabled option
when some value is loaded

The code below in struts

<html:select name="test" property="comments" indexed="true">
<html

ptions collection="collectionData" property="value" labelProperty="label"/>
</html:select>

shows the comboBox, but I want to disable when a specific value is loaded:
For instance , I make a combo of list of names. If the selected name is 'Paul', then the combo will load with Paul enabled to change but if the selected name is 'John', the combo will load with the disabled option (disabled=true).

How can I do using struts???
Thanks,

JAAS - security - Error page

I am using jboss-3.2.1_tomcat-4.1.24 and I am using JAAS authentication
In web-xml, when an user is not authorized to access some page, I am using the following code

<web-app>
...
<error-page>
<error-code>403</error-code>
<location>/NotAuthorized.jsp</location>
</error-page>
...
</web-app>

But the problem is that it doesn't work because it still shows the default error page. It should redirect to the page "NotAutorized.jsp". Does somebody know if it works in tomcat ??? Or is there another way to override the custom error page ???

EJB

How can I insert and update in 2 tables using EJB??
For example, after inserting a row in table of employee (a new employee) ,
I want to update a table of company (the field "number of employees"
will be added 1).
I am using session bean and entity bean but it seens that each entity bean is related with only one table.
Is there some pattern for this case???

problem in starting jboss

Sometimes when I start runnig Jboss there is a problem like:
***********************************************
Unespected signal :EXCEPTION_ACESS_VIOLATION occured at PC=0x6d44a8ce
Function name = (N/A)
Library=C:\jdk1.3.1_02\jre\bin\hotspot\jvm.dll
......
HotSpot Virtual Machine Error : EXCEPTION_ACESS_VIOLATION
***********************************************
There is more message but I didn't mention. I think this is enought to
show the problem
The strange is that sometimes it doen't appear.
The problems is that in more than 60% of cases this problem
is happening. This problem started exactly after downloading
service pack 3 of windows 2k. After that the jboss was never the same.
Does somebody know what is the problem??
Hardware??? or Windows 2k or the JVM???
