RE: Template -struts-template and generated HTML / templating using PUSH model
Many Thanks. It works OK now under Tomcat 3.2.1. Is there a problem in "flush" under Tomcat 3.2.1; in this case this patch would be appreciate for final Struts 1.0. Or is it my Tomcat configuration ?

The GetTag.java - the source behind the template:get tag that actually does the include calls pageContext and includes whatever content should go in. By default, the servlet engine should flush the buffer (that's what allows an include to go somewhere within your page). However, apparently some servers don't do that by default (WS 3.5.3 doesn't seem to). The solution is an easy one, but you'll need to recompile Struts. Under struts/src/share/org/apache/struts/taglib/template you will see a file called GetTag.java. Open that file. In the doStartTag() method you'll find the following code: pageContext.include(content.toString()); To fix your problem (hopefully, worked for me) add the following line above it: pageContext.getOut().flush(); So your end result will look like: pageContext.getOut().flush(); pageContext.include(content.toString()); By hardcoding the flush your problems should be solved.

I am beginning to look at Templating mechanism and so use the example struts-template using version pre-beta-2 (23/03/01). The result is a strange for me. Can somebody explain me this. On the first page, when I look at the generated code (look at the end of message), I got something where the side-bar.jsp and header.jsp is included BEFORE the tag; while from what I see in chapterTemplate.jsp, the should appear first.

The fact that I have two create each 2 files (introduction.jsp and introduction.html) is not really needed if you consider you have a little number of different templates to work with. Say you have only two templates (side-bar header content footer) (left-bar header content right-bar footer), it is too much for me to create each time the page that will use template:put. I have done that before I used Struts in a "request processor" by setting the value of a "content" field, forwarding to one of two pages template1.jsp and template2.jsp that uses jsp include tags. My plan was to do that in the findForward() method of ActionForwards and forward all the time to one of the 2 template pages that I have and setting the "content" value before. To speak "philosophically", but wishing to not re-open this debate, the PUSH method is for me more convenient that the "PULL" one for Page Templating Mechanism.

Re: ActionForm with no default constructor
I think this should work. The most likely reason I can think of for what you're seeing is incorrect settings in your struts-config.xml file. You might want to check the following: 1) The 'name' in your must match the 'name' in your . 2) The 'scope' in your must be specified as "session" in your case. 3) The 'type' in your must be set to the actual class you are instantiating (even if Struts won't be able to instantiate one of those). 4) The attribute name under which you are storing your form bean must be the same as the 'attribute' in your , or the 'name' if you do not specify 'attribute'.

I'd like to translate the following to scriptlet-free JSP. (Hey, that
rhymes!)
String focus;
if (request.getParameter("startAtTheTop") != null) {
focus = "field1";
} else {
focus = "field2";
}
The main problem I'm facing is that I need to be able to use 'focus' as the
value of a tag attribute later in the JSP, like so:
That means that the following approach does not work:
When it hits the expression in the tag, the JSP compiler
complains that 'focus' is undefined. Presumably, this is because the JSP
compiler doesn't realise, like we do, that one or the other of those cases
will be executed, so that 'focus' will indeed be defined.
In any case, the best I've been able to come up with so far is this:
This works, but it does seem rather clumsy. Is there a better way?

RE: using struts in a load-balanced environement
Yes. High-end servlet engines will replicate session state between one or more servers in the cluster; to how many it gets replicated depends on the specific implementation. For example when you cluster Weblogic servers, each new session is assigned a primary server and a secondary server. All updates to the HttpSession are replicated from the primary to the secondary. The trick is though (and my understanding starts to get a little bit fuzzy at this point) that you can't hold a reference to an object stuffed into a particular client's HttpSession object, call a method on that object which changes its internal state, and expect the servlet engine to respond to this method call and replicate the state to the secondary server automatically. There are two approaches here: 1. Whenever you make a change to the state of an object held in a client's HttpSession, put the object back into the HttpSession with the same name and object reference. This is the simplest approach. An alternative approach. 2. Make your session state objects extend java.util.Observable. The servlet engine's implementation of HttpSession would have to then add itself as an observer to all new objects coming into the HttpSession. The session state object would have to call setChanged() and notifyObservers() in any 'mutator' methods in order to ensure that the servlet engine is told of the state change. The second approach would tie you to whatever servlet engine implements that functionality, and thinking harder about it, I don't think it buys you anything over the first approach anyway. If there was a thread running through all HttpSession's and periodically checking whether the Observable objects in them had changed their state then it wouldn't be necessary to call notifyObservers() - but you would also leave it in the lap of the gods as to when exactly the servlet engine gets a notification that the session state needs replicating, a failure in the meantime could result in lose of the client's state. Does anyone know if there are engines out there doing it this way?

Once the support for using request scope was added, the example app was changed so that it will work correctly for *either* scope (request or session) for form beans. You are correct that the removeAttribute call is not required for request scope, but it doesn't hurt anything either -- and it is part of maintaining the compatibility so that this code will still work for session scope form beans.

It's been my impression that the bigger servers can maintain session across webservers.

Re: html:errors, how to keep html out of messages?
The tag generates output like this: (errors.header)CR-LF (message1)CR-LF (message2)CR-LF ... (messageN)CR-LF (errors.footer)CR-LF where the values in parentheses are keys into the application's properties file, and message1 through messageN are your error message keys. Since CR-LF is just whitespace in HTML, you have to either use (or , etc) in the messages themselves, or put your tag in a fixed-format block (e.g. ). Theoretically, you could grab the ActionErrors object from the request attribute in which it's stored, and iterate over the errors yourself, but then you have to get into looking the keys up in the right resource bundle, etc. If you really want to do something different, then I'm afraid all I can suggest is taking a look at ErrorsTag.java and perhaps writing your own tag based on that. -- Martin Cooper - Original Message - From: "Phillip Rhodes" <[EMAIL PROTECTED]> To: "struts-user-jakarta.apache.org" <[EMAIL PROTECTED]> Sent: Wednesday, March 28, 2001 12:35 PM Subject: html:errors, how to keep html out of messages? > I am using the html:errors tag to display my messages, but I find that I > have to wrap each of my message key values with a for them to > display properly. > > Is there a way that as I iterator through my errors, that I could output > the error message with the tag? > > Thanks! >

RE: Template -struts-template and generated HTML / templating using PUSH model
Harcq, I just ran into this problem myself with WebSphere. The GetTag.java - the source behind the template:get tag that actually does the include calls pageContext and includes whatever content should go in. By default, the servlet engine should flush the buffer (that's what allows an include to go somewhere within your page). However, apparently some servers don't do that by default (WS 3.5.3 doesn't seem to). The solution is an easy one, but you'll need to recompile Struts. Under struts/src/share/org/apache/struts/taglib/template you will see a file called GetTag.java. Open that file. In the doStartTag() method you'll find the following code: pageContext.include(content.toString()); To fix your problem (hopefully, worked for me) add the following line above it: pageContext.getOut().flush(); So your end result will look like: pageContext.getOut().flush(); pageContext.include(content.toString()); By hardcoding the flush your problems should be solved.

The fact that I have two create each 2 files (introduction.jsp and introduction.html) is not really needed if you consider you have a little number of different templates to work with. Say you have only two templates (side-bar header content footer) (left-bar header content right-bar footer), it is too much for me to create each time the page that will use template:put. I have done that before I used Struts in a "request processor" by setting the value of a "content" field, forwarding to one of two pages template1.jsp and template2.jsp that uses jsp include tags. My plan was to do that in the findForward() method of ActionForwards and forward all the time to one of the 2 template pages that I have and setting the "content" value before. To speak "philosophically", but wishing to not re-open this debate, the PUSH method is for me more convenient that the "PULL" one for Page Templating Mechanism. But I do not want to "mix" Velocity and Struts only""" to solve this templating problem. Any ideas ?

In struts-example resource file errors.header has "" tag, and errors.footer has "" tag. This reason why each error message must to have these pair tags. Hope this help.

Re: Initial security check
No. The init() method is called during servlet startup, not in the context of a request. No request means no response - there's no place for a JSP to go.

ahh but if that is the case. how much data must be send to the client before it does noticed it?

Why no body allowed in jsp:getProperty or bean:write?
In order for the designer to be able to view a default row in a table (that I'm generating using iterate and jsp:getProperty--or I could use bean:write), I want to stick in a body value in there as a dummy value. Then the designer can open up the jsp page in the browser without it having to be served by a webserver. Currently, those two tags don't allow bodies. Why? There's no reason not to allow a body, just ignore it, and then you could have the flexibility of being able to view the jsp page directly (without server) and have dummy values in there to see how it looks. Is there a tag or property or something that will make this work? Thanks, -joel shellman

To avoid thecosmetic ugliness, you can change the level of debug for the log in the tomcat server.xml file. The default setting is INFORMATION.

Create a WEB-INF directory in the servlets dir and copy struts-config.xml, database.xml AND web.xml into it (Keep WEB-INF with all the TLD's under web - both WEB-INF directories must be present). 6. Copy jaxp 1.0.1's (NOT 1.1.1's) jaxp.jar and parser.jar to the servlets directory of the strut-example webapp. 7. In the servlets directory, open struts.jar with WinZip. Extract the three DTD's (struts-config_1_0.dtd, web-app_2_2.dtd and web-app_2_3.dtd) into the servlets directory making sure you use folder names (so the files extract to servlets/org/apache/struts/resources). 8. Click on struts-example in the Admin Console under Default Server/Default Servlet Engine and click the advanced tab on the right hand side of the screen. 9. Down where it says Default Error Page, enter /ErrorReporter and then click Apply. 10. Start the Default Server via the Admin Console. You should see a whole bunch of ActionServlet messages in the default_host_stdout.log file with no exceptions. 11. Via a browser accessed the app using http://localhost/struts-example/index.jsp. 12. If it returns "Application not Available" then go back to the Admin Console, right-click on struts-example and select Restart WebApp. 13.

Iterate tag problem- can't find properties in the Collection elements
Well it is finally time for me to use the iterate tag. Unfortunately I
ignored the millions of past posts about the iterate tag- so if this
question has already been answered I apologize in advance :) However, after
searching through some previous posts and the documentation I can't
understand why this does not work. I am probably using the simplest form of
the iterate tag:
Is this working?
recentRequests is a Collection (an ArrayList to be exact) in session scope.
Each element in the Collection is a simple javabean with the appropriate
setters and getters (requestName, requestDate, etc...) The strange thing is
that the iterate part is working- verified by the output of the last in
the above example (if the Collection contains 2 elements, then it iterates
twice but all I get is "is this working"). The bean:write tags produce no
output. I have verified the content of the Collection using plain JSP, which
works as intended:
<% java.util.Iterator it = ((Collection)recentRequests).iterator();
while ( it.hasNext() ) {
com.bipi.plims.model.FermSummaryBean bean =
(com.bipi.plims.model.FermSummaryBean)it.next();
out.write(bean.getRequestName());
out.write(bean.getRequestDate().toString());
out.write(bean.getRequestBy());
out.write(bean.getStatus());
out.write("");
} %>
suggestions???
Thanks,
Bob
Re: Removing ActionForm's from context
Right, but notice the exact wording--it says "remove it only if the scope is set to "request""--but that's the main case where you wouldn't need to remove it. page and session removal would make sense, but request removal only makes sense in the situation you describe which I would think wouldn't happen all that often. -joel Jean-Noel Ribette wrote: > > I don't quite understand the the below quote from the example tour.

RE: Actions and Session Beans
There is a good description of what you want to do in an IBM Redbook titled "Design and Implement Servlets, JSPs, and EJBs for IBM WebSphere Application Server" (SG24-5754-00, August 2000). You can probably download the PDF from IBM's Redbooks web site. The techniques aren't specific to WebSphere. There is a patterns for a Targetable Commands, which it sounds like you're talking about. There is also a good description with code samples of using the facade pattern with session beans and the command pattern, which also sounds like what you want to do. It doesn't have anything about Struts, but maybe by looking at it you'll get some ideas. It's only 178 pages. Bill Hines Hershey Foods -Original Message- From: G.L.

Removing ActionForm's from context
I don't quite understand the the below quote from the example tour. The paragraph doesn't make sense. Anything in request scope will be removed after the request is over automatically. So there's no need to remove it just so if the user comes back later to the same page--it would have been long gone before then. Right? What is it talking about? Thanks! Before returning from a successful login, LogonAction also disposes of the LogonForm bean. This way, if the user returns to the index.jsp form later, it will be a clean form without the (old) login already entered. Note that LogonAction first checks to see if the scope has been set to "request", and then removes the bean from the request context, or otherwise from the default session context. The Struts best practice is to use request scope for single-page forms that contain all of your relevant properties, because there is no need to maintain such form beans across requests. Note that the example removes the LogonForm bean regardless of scope. This is for backward compatibility with earlier configurations. In your application, you should follow the advice of the configuration, and remove it only if the scope is set to "request". This way, the behavior can be changed just by editing struts-config.xml and reloading the application. " -- Joel Shellman KnOcean Interactive Corporation http://www.knocean.com/
Re: Connection to Oracle 8i datasource
I'm kind of new to struts, but I have this working.
Your data source configuration in struts-config.xml looks fine. You can check
your logs to make sure no errors are thrown when you start your server (I use
Tomcat 3.2.1).
In your code you set up datasource, as below:
javax.sql.DataSource dataSource = null;
dataSource = servlet.findDataSource(null);
I do it, like so:
DataSource dataSource = (DataSource)
servlet.getServletContext().getAttribute(Action.DATA_SOURCE_KEY);
Hope this helps,

Hello,
We at Tufan Infotech are evaluating Struts for using in our web application
development.
I am not able to connect to a Oracle 8i database and retrieve or update
data. The datasource configuration in struts-config.xml is given below.
The code snippet which tried to connect is given below
Connection con = null;
PreparedStatement ps = null;
ResultSet rst = null;
javax.sql.DataSource dataSource = null;
String str = "insert into metadata values (?,?,?,?,?)";
String type=((MetadataForm)form).getType();
String code=((MetadataForm)form).getCode();
String description=((MetadataForm)form).getDescription();
String sequence=((MetadataForm)form).getSequence();
String isDefault=((MetadataForm)form).getIsDefault();
ActionErrors errors = new ActionErrors();
try
{
dataSource = servlet.findDataSource(null);
con = dataSource.getConnection();
ps = con.prepareStatement(str);
ps.setString(1,type);
ps.setString(2,code);
ps.setString(3,description);
ps.setString(4,sequence);
ps.setString(5,isDefault);
ps.executeUpdate();
}
catch(Exception e)
{
errors.add(ActionErrors.GLOBAL_ERROR, new ActionError
("error.database.missing"));
}
finally
{
try
{
con.close();
}
catch(Exception e)
{
errors.add(ActionErrors.GLOBAL_ERROR, new ActionError
("error.database.missing"));
}
}
The above code is not updating the database. It thows an exception and
shows the message in 'errors'. One of the statements below seems to be
failing and gives a nullPointerException.
Would appreciate some inputs to solve the problem. Also would appreciate
code snippets used to connect to datasources (example Oracle).
Best regards

RE: Template -struts-template and generated HTML / templating using PUSH model
Merci. I will have a look at it.

Re: Template -struts-template and generated HTML / templating using PUSH model
J'espere, que cela prendra en compte l'internationnalisation. Les fichiers de resources, ne permettent pas de gerer des pages stylisées. Ce qui m'interesserait, dans un systeme de templates, ce sont des feuilles de style (pas xsl) qui s'appliqueraient sur des beans, et qui permettrait au graphiste de définir globalement comment s'affiche l'objet, puis de l'utiliser via des tags. a+ Cedric Dumoulin a écrit : > Hi Vincent, > > Have a look to Components proposal.
