Re: Checkboxs in a list
You can do this with the tag. - Use the same 'name' attribute for each checkbox. - Use a different 'value' attribute for each checkbox (probably obtained from your iterator). - Define the corresponding bean property as type String[]. When the form is submitted, your property setter will be called with a String array containing all of the values for the checkboxes which were checked.

Re: trying to get started with Struts 1.0b1
I had the exact similar problem a few weeks ago when trying to build struts with ant. I was told that this usually happens when either the xercies(sp ?) library is in the class path before the jaxp.jar or there is an old parser.jar in the class path. Either way it is a classpath problem, once I took care of that it worked ok. I can't recall more, though I did get some insightful explinations. So search the struts www.mailing-archive.com for 'sealing violation'. Also check the ant mailing list as I have sen this mentioned in there also. -Rob Liz Anderson wrote: > > Im trying to convert an example app that was running in struts .5 (its the > auctionstation3 for those of you familiar with that example) to run in > 1.0b1.

Since you are running Tomcat 3.x, the XML parser that it uses (normally found in the $TOMCAT_HOME/lib directory) is already visible to web apps, so you don't need to add a second one in WEB-INF/lib. If that's not the problem, check your class path and/or system extensions directory ($JAVA_HOME/jre/ilb/ext) for extra XML parsers. > Liz Craig >

Re: Checkboxs in a list
Im studying Struts yet, but I do this as follow:
To process all files marked (the files not marked doesnt appear:
String[] files = request.getParameterValues("file");
if (files != null) {
for (int x = 0; x < files.length; x++) {
* process files[x];
}
}
Is there another way more easily?
Is possible do the same thing with tag ?

Sounds good to me, since both tags support the name attribute. This makes
it relatively easy for current users of html:options to change their
current code from:
collection="myBeanName"
to
name="myBeanName"
rather than to
collection='<%= pageContext.getAttribute("myBeanName") %>'

RE: More on my copyProperties/EJB woes
Although copyProperties to an entity
bean might work, it would be making a call through the remote interface
each time it sets a property on the entity bean. I think it's good practice
to minimize the number of remote calls made to an EJB. (Often in practice the
calls are not really remote but it's good to pretend like they could be.) That
would allow you to separate your JSPs and EJBs or use Tomcat for JSPs and
Weblogic for EJBs. Normally instead of calling set methods on an entity bean
from the web tier, I call a session bean and pass a simple JavaBean to it that
isn't tied to Struts, often the bean may have been nested in an ActionForm. Then
I have a create or an update method in the entity bean that accepts
the JavaBean as an argument. I don't always put all the getters and setters
for individual fields in the entity bean remote interface unless I need them.
Sorry
if this isn't helpful, I would be interested to hear if anyone disagrees.

Checkboxs in a list
Does anyone of the best approach for the following situation? I wish to have a list of files for processing with a checkbox on the left hand side of each file to indicate if the file should be processed or not. I'm looking at how to do this in a single form with a tag to list the files. If I use the tag the problem is that the names on the checkboxes are all the same and I can't distinguish between them. Any ideas? Paul Jackson Meridian Informatics Sydney, Australia Ph 8233 7564 Fax 8233 7533
Re: Getting Locale from a non-struts servlet
I would be pleased if I would be able to specify a default local in web.xml for struts (as an init parameter). All the other ways can be late to override the system/servlet-engine default locale. (E.g. if you use the servlet container's authentication the user can enter at many different places and it is simply annoying to start every action with locale checking.) Every user sessions could inherit this value unless they override in the http header or in some programmatic way. I can't see any drawback but test the idea before applying a feature request on Bugzilla. incze
RE: Alternative Frameworks - continued
While the push model has traditionally been encouraged with Turbine, you can also use pull-MVC model without any major problems. Whether the push or the pull model is right for you depends on the nature of your application. The learning curve associated with Turbine is a little steeper, but it is also more powerful than struts. For one, you are not limited to JSP for the presentation. In fact, I would imagine most people that use Turbine don't use JSP. There is a slick templating language called Velocity (http://jakarta.apache.org/velocity), and I would imagine that more often than not this is used in favor of JSP with Turbine. I am currently on a project using Turbine/Velocity and it works very well. In all fairness it was a pain in the ass to overcome some of the shortcomings in the documentation, some of it was outright misleading.

Re: Getting the tag to display on multiple lines
Just specify the property attribute of the html:errors tag. So, for
example, in your validate function you might have something like:
errors.add("roles", new
ActionError("error.reqaccess.role.invalid"));
to indicate an error in the "roles" field. Using:
in your JSP will show only the errors associated with the roles
field. Repeat this for as many fields as you have and use the appropriate
parameters to errors.add(), and you should be able to place errors in the
appropriate locations.

Does anyone know of some good JSP/Servlet MVC Frameworks besides Struts?
Passing on multi-select values from form to form
I have a form that submits from the form page to an interrim 'confirm/edit' page it and from there goes to a save page. (Ofcourse it has a Form bean attached to it). However, it seems I need to pass on the initial values useing html:hidden tags from the Form when selecting Edit on the confirm page (going back to the Form page) . First question, is that the right way to do it? If I don't do it, the Form page tries to populate the form again and starts from scratch populating the form even though the form already exists populated. Second problem. If I DO use the html:hidden tags it seems I can't pass on any multi-select values because the html:hidden tag only supports Strings. I guess this is inevitable? Martijn.

Re: Digester order of events
Actually, there's a setter in MyBean (setProp) but no corresponding "prop"
attribute in the XML. At runtime, the JVM can't find type SomeType, and
it looks like that causes Digester to not ever call setName(). If I
comment out the first 4 lines of the MyBean class (all the
SomeType/setProp stuff), things will work. Also, if I add type SomeType
to my runtime CLASSPATH, things will work. Please note that I had an error
in my original post: I never actually do "SomeType p = new SomeType();"
(that line should be "SomeType p;"), that's why there isn't a runtime error.

Whether the session ID actually shows up in the generated hyperlink or not depends on whether the servlet container thinks your client has cookies enabled or not. On the first response that is part of the session, the container has no way to know - so it sends the session ID both ways (as a cookie and in the URL). If the second request contains the session cookie, the container says "aha, this client supports cookies" so it stops modifying the generated URLs on hyperlinks. The call to response.encodeURL() is still happening; it is just returning the URL without modifying it.

Look for a java.util.Locale object stored as a session attribute under key "org.apache.struts.action.LOCALE". In a program, you could use the symbolic string constant Action.LOCALE_KEY instead (from the org.apache.struts.action.Action class). Be sure that you enable Locale tracking if you want this to work, by setting the appropriate initialization parameter for the controller servlet (parameter "locale" should have a value of "true"). Also, if the first request in your session is to a JSP page instead of the controller servlet, you can have the page save the Locale by using tag: ... contents of your page around it. > I have a non-struts servlet which I want to try to pull the Locale object > from. > > Thanks, > > Neal > > Craig McClanahan

This is definitely strange. How is your bean class declared? Does it say
"public class Xyz" at the top? Does it implement one or more interfaces?

Yes, it appears to be a bug. The "&" sequence is what you get when
you URL-encode a string containing an ampersand, and it looks like Struts
is doing that a little bit too aggressively.

RE: Strut Books
Here is some input from someone who started using struts from scratch a week ago. So it might be valuable. In a book on struts, I think it would be really good to emphasize on the 'why' and not only on the 'how'. What I find with a lot of information and examples on the struts site is that there is a lot of information on how to do certain things (with a lot of examples) which is pretty good. But because there is a lack of explaining 'why' things work the way they work, it is not always easy to go beyond functionality that is used in the examples. Simply because the user is not always informed on why the things work the way they work.

Getting Locale from a non-struts servlet
Does Struts store the client's Locale in their session somewhere? If so, how would I access it? I have a non-struts servlet which I want to try to pull the Locale object from. Thanks, Neal
RE: Struts with IBM VisualAge for Java
I said it is 'imminent' - meaning it should be out any time now but it is not out yet. Keep looking and also you might get more info on IBM's newsgroups.

Re: Question about struts application model (DataSource, Business Logic beans)
> My problem is that > access to the DataSource is through the servlet.findDataSource() call. Struts stores the JDBC Connection pools as servlet context attributes (in JSP terms, application-scope beans). You can also access them that way. If you do not specify a name in the Struts-config file, it uses a constant value. If you specify null to findDataSource(), it uses the same constant. But you can also access the pools using your own labels (or the Struts constant) without using the servlet method. > Carles Pi-Sunyer wrote: > > Hi, > > I'm using Struts for a new application that I'm developing.

Struts nightly build not working on Tomcat 4 nightly build
Hi, I'm trying to run struts-example.war (from the Struts nightly build) on the latest Tomcat 4 nightly build; the relevant files I'm using are: * jakarta-struts-20010312.zip * jakarta-tomcat-4.0-20010312.zip Tomcat 4 seems to be happy enough in its own way, but on deploying struts-example.war and going to http://localhost:8080/struts-example/ I'm getting the famous "javax.servlet.ServletException: Cannot find message resources under key org.apache.struts.action.MESSAGE message" error. Hmmm. Any thoughts? Not sure if it's a Tomcat or a Struts problem.
