RE: Help on ApplicationResources
Kamakshya,
There is an implementation of this available at
http://sourceforge.net/project/showfiles.php?group_id=49385.
Go to the above site and about halfway down the page you will find a project
category called:
MessageResources Impls
Under this you will find a package called:
ojb-msg-resources
You can download it along with the demo application to see how to apply it
to your application.
HTH,
Todd

Subject: Help on ApplicationResources
Hi All,
We are using struts framework for building an application for a client.
In the system, the client wants to have all the error messages, labels
etc in the database instead of having them in a properties file. Please
let me know that how can we extend the necessary packages provided by
struts with a minimal changes and with the ability to continue using the
normal functionalities provided by struts like bean:message, errors,
ActionErrors etc.
Thanks and Regards,
Kamakshya

RE: Converting a ResultSet to a List of POJOs
Matt,
If you pull the scaffold project from
http://sourceforge.net/project/showfiles.php?group_id=49385, there is a
class called ResultSetUtils which provides the below methods for mapping a
ResultSet to a Collection of a given class or returning a given element from
the ResultSet. It uses reflection and the meta data of the resultSet in
conjunction with BeanUtils and PropertyUtils to invoke the setters on the
POJO.
Seems to work fairly well.
Regards,
Todd G. Nist

Subject: Re: Converting a ResultSet to a List of POJOs
There are no people more expert in Struts than you Matt.
I think you can use RowSet to wrap a ResultSet, and RowSet has a
toCollection or getCollection method. (Or just don't user ResultSet at
all, just use RowSet, Sun has default implementation in JDC, but
Orcale has an extra download, other do to).
Worst case you write your own helper object.
But... I would use a DAO layer(and not code to JDBC), it will be
cheaper/faster in the long run.
Consider writing a console generator (I have one, in CVS at bP for
iBatis that jsut enmerates all tables in DB) that takes a SQL Strings[]
in XML file, and based on that queries the DB, and writes a real DAO and
beans (and can do this anytime, for any of your projects). (I do not
know how well Hibernate works with SQL).

Dear Struts Experts,

get
the point. I'm wondering if there's an easier way - so I could do
something
like this:
ResultSet rs = stmt.executeQuery(SELECT ...);
List objects = FancyUtilitity.convertResultSetToListOfObjects(rs,

Hibernate let me do this very simply - and I miss the fact that I could
type
a line or two to get a List of POJOs.
List users = ses.createQuery(from u in class + User.class
+ order by u.name).list();
I've looked at the RowSetDynaClass (http://tinyurl.com/mekh), which has an
interesting way of doing this - is this the recommended approach in the
JDBC world? Here's an example using it:
ResultSet rs = stmt.executeQuery(SELECT ...);
RowSetDynaClass rsdc = new RowSetDynaClass(rs);
rs.close();
stmt.close();
...;// Return connection to pool
List rows = rsdc.getRows();
...; // Process the rows as desired

Struts has a much better control, while JetSpeed has established portlets and facilities to connect devices to portlets. The problem with Jetspeed is that it is binding to Turbine, while Struts allows complete separation of controller framework and presentation layer. Struts-Tiles enable 1 single web-page view rather than portal view and portlet view. With the release of JSR-168 specification of portal/portlet container based on standard Servlet container, it makes a lot of sense to refactor Struts framework to work with standard Servlet / Portal /Portlet container. Then an effort to refactor Jetspeed portlets into this framework. I wonder if any developer has playing with this idea? I heard Craig and Cedric have something under their desks, and not ready to share yet? Am I right? It doesn't sound like there's much left for Struts to do once you use Jetspeed (or Turbine, its underlying framework) for authentication, templating, and layout. Once you're talking about providing content to individual portlets in your Jetspeed installation, you can do it with much less work than adding Struts in to the mix.

You can find the a taglib for this at:

If you would prefer to use a scriplet then the following will work:

}
/* Odd row */
td.row1 {

RE: Help - xml to pdf using struts
Mark,
I have tested this out on 5.0, 5.01, 5.5, 6.0.26 and have not encountered
any problem with the page being displayed, what release of IE are you using?
I have attached a small servlet which will render a page straight to the
browser, at least under those listed above.
Hope it helps.

Yes. The problem with IE is that it doesn't show the file and you get a
blank page. This note at the fop site says:
Some browsers have problems handling the PDF result sent back to the
browser. IE is particularly bad and different versions behave differently.
Having a .pdf on the end of the url may help.

RE: IFrame Newbie Looking for IFrame Advice
Stephen, As to the first part of your question, I can not say for certain if WebLogic will have the same problem with IFrames, I do not encounter any with JBoss, and since they are inline as part of the main HTML document I don't believe that you will have an issue. As for updating the surrounding stuff, yes it is possible. However, if the content received by the iframe is to update surrounding elements in the DOM, then the content must be received from the same DOMAIN otherwise you will receive a security exception by default. The other issue is if you must support Netscape versions prior to 6.x (I think it is 6.b1, not sure). I have used this for RPC invocation of validation and population of certain components in web-apps, generally takes around .5 seconds for the round trip to the server to have the action generate the results. The results are returned to the iframe which then use some standard javascript to populate the appropriate fields with values. Works good for selection list and drop downs rather then having the entire screen re-paint every time an option changes. Also works well for field validation which must take place on the server. What I have done is to simply create a iframe 0px by 0px and then use it for the RPC. Let me know if you have any questions. Regards, Todd G.

Are there any gotchas with iframes in a J2EE / Struts app that I should be aware of? For example, the WebLogic documentation states that normal frames can cause problems with the session id getting lost if improperly used. Could this be a problem with iframes too? Also, what if, as a result of the user submitting something in the body page contained within the iframe, we need to reach out and update the surrounding stuff. Is that possible? Thanks!

Hi Lisa,
That looks similar to my solution. The biggest problem I had was with
getting IE to display the PDF inline without a PDF in the URL Using a
Struts action, I wasn't able to get the URL to change at the appropriate
time with a redirect. In the end, I sent the pdf as an attachment which
gives the open/save prompt. Were you able to get around this problem?
Thanks, Mike

Here is the bit of my action that deals with the pdf creation.
First I transform xml to fo using xsl (and Xalan). The result is written
to an InputSteam, which is passed into FOP. The result from FOP is then
written out the client and the content type is set to application/pdf.

I am in the last stages of implementating a Struts application. I now

to complete the reporting side. This basically consists of displaying
xml

XTags) but how do I render an xml to fo transformation to pdf by using

the

the

Hello Vijay, You can use the length and offset attributes of the iterator tag. The length is used to tell the iterator the number of times/number of items to retrieve from the collection. Offset is used to indicate the offset into the collection.

RE: related to: Re: #2 - Use DispatchAction to organize related operations
I have to ask a question; Why not use a filter to handle this? The filter
will be called before any components of struts are invoked. It has access
to the request, response and session and can handle forwarding the request
to the login page or error page if they are not currently logged in. If
container managed security is used, it will get invoked prior to the filter,
which can then check the getRemoteUser() and the session to ensure that they
have been logged in and perform any setup that is required for creating a
user object and storing the information in the session or wherever. The
filter can then chain to the requested page with the chain.doFilter().
Any reason not to do this?

Chuck is absolutely correct on the linear progression of action processing.
I, too am overriding processPreprocess and it works beautifully. Besides
increasing security, it cuts down on unnecessary CPU bandwidth.

Rick,
catch this earlier. I had implemented something along these lines awhile
back and soon remembered that the ActionForm is populated and the

Subject: Struts with WAP+HTML projects
Hello All,
I am working on a project which is for a portal which serves to HTML and WAP
clients. This project is developed using a home grown MVC model + jsp + XSL
So one jsp serves many types of clients by looking up the header sent by the
device and applying the right XSL file .. thus creating WML or HTML output
depending upon what the client device type is. The application logic remains
the same no matter what the client device is.
We are having lot of problems with our home grown MVC framework and want to
use struts ... from all the initial examples it appears that struts is used
only for jsp pages serving HTML output.
How can I use struts in a multi channel (WAP, HTML, PDA) portal like ours? I
don't want to write a new jsp per device type. the jsp and action classes
should remain the same only the XSL changes per device type.
I would appreciate your help, also please share your experience about using
struts in a WML+HTML project.
regards,
Abhishek.

RE: Using 2.3 Filters and Struts
John,
The actual filter in deployment here only stores the user object once in the
session. I thought that was a major oversight on my part and I had to go
check the actual code when you mentioned it; Thanks for the comment. The
filter, checks to see if the user object is valid and if not, but the user
has been authenticated by the container, then the user object is created and
stored in the session, otherwise the user is sent to an error.jsp or
login.jsp page. From that point, the filter always checks the user object
in the session, but does not create it again. This was left out during the
cutting and pasting of code, sorry about that. So with regards to you first
question/comment, I would agree with creating the user object only once.
Our filter mapping is handled at the /app/do/* and /app/pages/ level where
app is the specific web application. All our actions are currently mapped
to the /do/* and you are required to be logged in to perform any action
under specific applications, i.e. a Buyer Site and Supplier Site exchange
type application. We also have the basic portal or informational site which
is a different /app and requires no authentication to get into. All .jsp's
are stored in the pages directory with the exception of those required to
support the login.jsp, error.jsp and index.jsp.
When a user first hits the site they are presented with the index.jsp which
is using tiles to define the screen layout. One of the tiles created is the
login tile which allows a valid user to login to either/or the
Buy/Supplier Site. The links for Buyer/Supplier point to an action
/app/do/loginAct?action=Buyer or /app/do/loginAct?action=Supplier. Since
the /app/do is a protected resource the container presents the Form based
login.jsp page. If the user is authenticated, we get the request in the
filter, create the user object, and the pass the action to the loginAct.
The login action is our case does little more then forward the user to the
appropriate page based on login success. If there are any problems with the
login, the filter catches them and forwards the user to an error.jsp page
with the appropriate error messages.
The above could be done just as easily in the action, but we opted to do it
in the filter since at some point we my use our on security model and by
pass the container implementation completely. So by doing things here in
the filter, we are all set if we decide for any reason we need to change the
flow of the application. (I think)
Regards,
Todd

Thanks Todd!
I've developed a very similar solution. Here are a couple of
questions/comments about the code:
1. I noticed that you are storing the user object in the session every time
this filter is invoked with a valid user. My solution sets the user object
once in the session after a successful login in the LoginAction class. Do
you see any issues with setting it once?
2.How do you handle the filter mapping? Do you have a directory that
contains all the pages that a user has to be logged in to be able to view?
Thanks for the help,

In your filter, you can do something like the below. We have implemented
something similar to this but have container managed security on top of it.
So the container managed security gets invoked first and then the filter,
processes the request. This lets us add any additional information to the
session to ensure logged inness. Now when the session times out, the any
resource which is protected is first processed by the container managed
security, and then the filter is invoked.
You could just as easily use only the filter for ensuring logged inness.
Hope the below helps.

You could try something like the below: for cancel you could do this: html:image src=images/cancel.gif border=0 property=org.apache.struts.taglib.html.CANCEL/ for the others you would need to do something like: html:link href=javascript:submit(); html:image src=images/save.gif value=save border=0/ /html:link Regards, Todd G.

Subject: Poolman query
Hi,
Sorry about this out of topic query. But looks like this is the
only place where I can get some help on Poolman.
I am struggling in setting up poolman to run in silverstream
server.
All I try to do is, set up a simple poolman configuration just
to access a database in my local server. I am not using any JNDI
name.
Configuration Details :
Silver stream version : Silver Stream 3.7.3
Database: Sybase adaptive server
anywhere 6.0
Poolman version : 2.1
My poolman.xml looks like this
datasource
dbnameCBSData/dbname
driverjdbs:poolman://localhost:80/CBSData/driver
usernametest/username
passwordtest/password
minimumSize0/minimumSize
maximumSize10/maximumSize
logFile/home/poolman/logs/testdb.log/logFile
/datasource
The following is the snippet of the code
try {
// load the PoolMan JDBC Driver
Class.forName(com.codestudio.sql.PoolMan).newInstance();
} catch (Exception ex) {
System.out.println(Could Not Find the PoolMan Driver.
Is poolman.jar in your CLASSPATH?);
}
Connection con = null;
try {
// establish a Connection to the database with
con = DriverManager.getConnection(jdbc:poolman://CBSData);
// Use the Connection to create Statements and do JDBC work
Statement stm = con.createStatement();
} catch (SQLException sqle) { sqle.printStackTrace(); }
finally {
try { con.close(); } catch (SQLException csqle) {}
}
I get NullPointer exception asa I reach the point where I try to
load the JDBC driver.
Hope the provided information will do. Any help is greatly
appreciated.
TIA,
Jerome.

PropertyMessageResourcesFactory Question
Title: PropertyMessageResourcesFactory Question
I have a few questions on the creation of a custom MessageResourcesFactory which I am hoping someone can help answer. We have a database which contains most of the translation string for our application, so I would like to create the MessageResources from here in addition to the standard ApplicationResource.properties file. I have written my own PropertyMessageResourcesFactory, modified my web.xml so that Struts would use this factory, and extended the ActionServlet to call a method to load the data from the database. I thought this would provide a simple yet elegant solution because nothing else would need to change for it to work.
My questions:
1. While it appears that my code is adding the content of the tables to the messages HashMap, when I go to reference them with a bean:message key=MLSBuyer.title I get the following exception:
Missing message for key
MLSBuyer.title' javax.servlet.jsp.JspException: Missing message for key
MLSBuyer.title at
org.apache.struts.taglib.bean.MessageTag.doStartTag(MessageTag.java:298) at
org.apache.jsp.CompanyZoomBody$jsp._jspService(CompanyZoomBody$jsp.java:84) at ...
I have not implemented the getMessage(Locale locale, String key) method in my custom PropertyMessageResources class, I was hoping that the messages that I created would become part of the default bundle/messages hashmap and therefore would be available to the Struts frame work. This does no appear to be what is happening. Is there a specific Servlet context attribute or some other value which needs to be set for these messages to be included in the standard bundle? What is the difference between Action.MESSAGE_KEY and Action.MESSAGES_KEY?
2. What else needs to be done to make these available in the default bundle so that the Struts frame work can use them without us having to implement the getMessages() methods? Or can this be done?
3. Are there any major issues/drawbacks with using the database like this for building the messages HashMap? We will still use the ApplicationResources.properties file where appropriate, but since the database already has the other translation information in it, it seems logical to use it, but I am open for other views on this.
I have attached the MessageResourcesFactory, DBMessageResourcesFactory and the actual class which is created from within the factory, BasePropertyMessageResources. Below is the initApplication() method which we have added to the extended ActionServlet to invoke the method dbLoad() in the BasePropertyMessageResources class.
Thanks in advance.

RE: PropertyMessageResourcesFactory Question
I would like to thank Erich Meier for his response and help in resolving
this.
The problem wound up being with how the locales had been stored in the
database. Only the country code had been stored, and not the associate
language or variant, i.e. US, FR, AR, Since the default getMessage()
uses the localeKey() method which, returns a string in the form of
language_country_variant, i.e. (en_US, fr_FR, es_AR, ...), and then appends
this to the key requested, the called failed since the values stored in the
messages HashMap as keys were in the form of country.key. With a quick
change to the database, the default getMessage() works fine.
What a silly mistake.
Sorry for the wasted bandwidth but thought someone else may find this useful
in the future.
Again, thanks Erich for the assistance.

Todd G. Nist

RE: Design Help
James,
I was reading through the archives when I came across the below post. If
one follow the design as you have shown below, dose the Delegate get stored
in the form? If it does then does one reference the DAO via the delegate
with a nested type syntax in the view/JSP?
So if I have a Delegate, which in you example does a viewall, I first
create the delegate, create the DAO and populate it and then store the
Delegate in the form with some standard setter and getter method:
FORM:
public void setDelgate(Object d) {
this.delgate = d;
}
public Object getDelgate() {
return this.delgate;
}
Then in the view how do I reference the values in the DAO?
Is it just something like:
bean:write name=ViewAllFrm property=delegate.dao.value/
Where dao is the Data access object, and value is a getter in that object.
Is this the correct flow or am I missing something?
Thanks in advance.

Todd G. Nist

Subject: RE: Design Help
1) The relationship is a starting point. Basically, I would not pass an
ActionForm to my business delegate (RentalBean). Doing so ties that
delegate to the web interface. If you were wanting to create a Swing client
in the future, you would have to create seperate business delegates for it.
Try to abstract your business delegates from your view ( see code below ).
2) Use a constructor that requires no params, but provide 'public void
init(...)' params to initialize the state of your bean.
3) Depends on the scope of the application. I usually provide several
different applications, all depending on the business cases (admin app, web
user app, swing app, web services for b2b,...).
4) Start off with a base data access class that has general methods. The
methods should provide a way to create jdbc connections and close
connections, statements, and result sets. You can also have query builder
methods in this class that don't tie it to any single use case.
If you are wanting the application to scale upto EJB in the future, you are
best to use delegate objects like you are doing (RentalBean).
If you are wanting to use an Action class for every use case ( adding a
rental, editing a rental, viewing a rental, deleting a rental), then you
don't need to the action property . If you are wanting to use one class,
then use the 'action' property in the request, this is how id did it below.
The data access object (RentalDAO) should be an interface. You should use a
factory that uses a JNDI value to select the DAO object. This allows you to
change databases by just modifing a value in the web.xml file and
redeploying your app. I wont go into this, but check the java petstore app
(1.2.1) for examples.
With the following code, only the BaseAction, RentalForm, and RentalAction
are tied to the web client and struts. The business delegate
(RentalDelegate) and the data access object(s) (BaseDAO and RentalDAO) can
now be used with other clients (web, wap, swing,...).
Lets rewrite some of the pseudo-code you sent:
-- Code for BaseAction.java --
public abstract class BaseAction extends Action {
//Don't use class variables in Action objects. These are not thread
safe.
//protected String action=null;
//provide this method just in case any of your subclassing actions want
to do some pre-initialization processing.
public ActionForward prePerform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
//could do custom authentication or something else.
//base implementation returns null.
return null;
}
//this is good. I do this on all of my projects. Also got the idea from
Ted Husted and a few others on the list.
public abstract ActionForward performAction(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException;
//proxy method
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
//WE CANT DO THIS BECAUSE Action OBJECTS ARE NOT THREAD SAFE.
//Find out what we are doing (Create,Edit,Save,Reset, Delete, etc.)
//action=request.getParameter(action);
//if (action == null)
// action=mapping.getParameter();
//catch all uncaught exceptions. Provide global
