RE: Arraylists/Collections
It depends on the database you are using.
If using oracle, then you can create a new datatype in database to store
array of numbers(if you require to work with
Collection of number)
Then you can pass a array of numbers to stored proc using the setArray
method
The code snippet is as follows:
--Creating a type (a datatype stored in database)
CREATE OR REPLACE TYPE ENT_GENERIC_NUMBER_TYPE AS TABLE OF number;
--In java layer suppose you have a collection of integer objects (say
numlist)
ArrayDescriptor numberArrDescriptor =
ArrayDescriptor.createDescriptor("ENT_GENERIC_NUMBER_TYPE",
connection);
Array numarray = new Array(numberArrDescriptor,connection,
numlist.toArray());
Preparedstatement.setArray(1, numarray);
-- DB layer accessing the array
PROCEDURE arraytester (
numarray inent_generic_number_type,
)
Is
Begin
FOR i IN numarray.FIRST .. numarray.LAST
Loop
dbms_output.put_line(numarray(i));
End loop;
End;
Similarly you can create type of any oracle
datatype(number,date,varchar2)
Hope it helps
Thanks,

Is there a proper way to pass an arraylist/collection to a pl/sql

RE: preventing user from validating twice
You can use savetoken(request) method for generating a token (when loading the
screen)and
Cheque for the existence of token using istokenvalid(request) method for ensuring that
you do not submit same data again.
Code in action wld be like
isTokenValid(request)

Subject: preventing user from validating twice
Hi,
i think it must be a FAQ, but i did not found anything on
this issue.
When my user submits a form, the action executes an SQL
Insert in the DBMS.
What happened is that when user click twice, the second
inserts fails with SQLException.
What is strange, is that i cannot reproduce it in WSAD, but
it happens on a full Websphere.
Is there a way i can know that a user already submitted a
form ?

This arraylist contains a number of Site objects which have the properties siteName, address1, and city. This is getting displayed correctly. Now when processing the form, I am wondering whether in struts there is a way to retrieve these as objects and automatically populate setSitesList(ArrayList) method, rather than manually use request.getParameterValues for siteName, address1, city, create individual Site objects, add the site objects to an arraylist with Site objects and finally pass the list into setSitesList(arraylist).

Yes you can have any number of struts-config file. You have to name them differeently though and put allof them in WEB-INF folder. Then declare all the struts-config files in web.xml E.g action org.apache.struts.action.ActionServlet config /WEB-INF/struts-config.xml, /WEB-INF/a.xml, /WEB-INF/b.xml Where struts-config.xml,a.xml and b.xml are the struts config files Thanks, Satish -Original Message- From: sougata [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 15, 2004 5:29 PM To: Struts Users Mailing List Subject: can i have multiple struts-config.xml Hi All I have one question.Can I have 2 struts-config.xml for one web application.

You are getting the error because you have not defined a scripting

Simple way of doing that is using the bean:define tag

Subject: RE: Cannot Find Bean in Any Scope
Sorry for not being clear about the problem that I
have.
1. I have a JavaBean, which is named as ThreadBean
with lots of properties.
2. My ListThread.java class extends Action. In that
class, I created a collection of beans. Each of those
beans is a ThreadBean.
3. By the end of the ListThread.java, I passed those
beans to my JSP in the request scope this way:
request.setAttribute( "ThreadBeans", beans );
4. In my JSP (I did import the ThreadBean), I have
<%
Collection threadRows = ( Collection
)request.getAttribute( "ThreadBeans" );
int odd = 0;
Iterator iterator = threadRows.iterator();
while( iterator.hasNext() )
{
odd = ( odd + 1 )%2;
ThreadBean threadBean = ( ThreadBean
)iterator.next();
.
}
%>
5. when I tried to write out the properties; for
example:
<%=threadBean.getSender()%> <%=threadBean.getThreadReplyCount()%>
<%=threadBean.getThreadViewCount()%>
..
I got the error message:

Subject: Help with validate ActionForm method
Hi,
I'm using ActionForm for one of my pages and I implemented the validate method as
follow: public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (isFieldEmpty(login)) {
errors.add("login", new ActionError("loginForm.login.required"));
}
if (isFieldEmpty(password)) {
errors.add("password", new ActionError("loginForm.password.required"));
}
if (errors.isEmpty()) {
if (!isConnected(login, password)) {
errors.add("login", new ActionError("loginForm.msgs.wrongLoginorPassword"));
}
}
if (!errors.isEmpty()) {
getLogger().info(this, "Failed attempt to log in : [" + login + "/" + password +
"] from : " + request.getRemoteHost());
}
return (errors);
}
You can see that I log each time someone fail to log in.
When the validate method returns an empty Error Array, login/password are checked in
an Action object.
The problem is that I have the following trace in the log when somebody successfully
log in : 09:26:54,500 INFO [lex.LoginAction] User logged in [login/pwd] sessionId
[773BB4634682A159DC680847073E4EC8] from [10.10.10.10] 09:26:54,587 INFO
[lex.LoginActionForm] Failed attempt to log in : [/] from
: 10.10.10.10
These traces obiviously means that the validate method is called twice, the second
time the ActionForm having empty fields.
Does anybody know why such a thing would happen
Thanks

RE: Semi-OT: Organizing WEB-INF/lib dir...
Instead of you putting all the jar files in the WEB-INF/lib folder
I would suggest that create a directory structure for libraries aoutside
WEB-INF
Advantages of this is this approach is cleaner and easily mantainable
as
You can add any new libraries with minimum of effort
e.g the directory structure may look like
Application
libraries
struts
hibernate
Web-inf
lib
classes
And then use ant to include the jars in the classpath. All the web
containers garantee that if you
put the path of all the libraries using the manifest.mf (which is
created when you create ur
Application's WAR file) then the web container will include them in ur
application's classpath
A sample ant target for including the path of libraries in manifest.mf
is given below
Where ${project.manifest.classpath} contains the path of all the
libraries. This has to be relative to web application root and not
absolute path
myweb.war -- the application's war file
${jar.dir} -- the directory from which to jar the files
Please revert to me in case you require any other details

Quick question for the people more versed in web apps than me, can you
organized your libs in your WEB-INF/lib dir into separate sub dirs? I
ask because my project is using Struts and Hibernate right now, and
there is a such a mish-mash of JARs forming in my WEB-INF/lib dir, that
its hard for me to upgrade the right jars when a new release comes out.
I'd like to have something like:
WEB-INF/lib/struts
WEB-INF/lib/hibernate
or something to that extent. Can I do this?
