whart is the best web application server for developers?
Dear friends, I use jrun4.0 as web application; but this server now has made some problem for me. Can you offer me a nice web application server during development? Can you e-mail me the URL for comparing between web application servers? Thanks.
Re: whart is the best web application server for developers?
Reza, I would be very surprised if most members of this forum did not recommend Tomcat if you are doing JSP / servlet/ struts style development. There are also corresponding forums fot Tomcat, so they can aid you. There are other packages which might be of interest, but from a development point of view, you would definitely find more assistance with Tomcat. Struts comes bundled with it at Version 4, so it is pretty ready to go. I am currently using JDeveloper for my sins, as it is strategic tool for the company who is paying for my work. It can be downloaded from Oracle under development tools (if you are interested). Obviously it is biased towards Oracle and its associated platforms (Oracle Application Server) , but you can develop and test reasonably easily with it , as it has its own embedded containers for testing your development. It has a good debugger which allows you to step through your code if you want to. Others can tell you about their experience with tools like JBuilder.

Tomcat http://jakarta.apache.org/tomcat JBoss/Tomcat http://sourceforge.net/projects/jboss I can't help you with the comparison, but I usually use JBoss with embedded Tomcat (even if I am only taking advantage of the servlet container). I really like the automatic hot deploy/redeploy feature.

Pass parameter to the same JSP Display parameter value into i/p bean field.
My app (simplified) ProductSearch.jsp display a search box (searchForm) for product name -- Action - Get name string create product bean -- (AGAIN) ProductSearch.jsp display list of products bellow the search box. -- In the list display QTY from product bean but allow user to change it submit every line to GetPrice action with changed product bean (changed qty). Questions: 1Any example of similar code ? pass parameter to the same JSP (preferred request scope) 2A table row displays i/p bean property as well as allows user to change any such example? 3Basically for some reason my parameter passing is not working if any one wants to help Ill send the code. My guess I do not understand bean creation / resetting. Thanks Harshal. - Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now
some basic questions
I'm kinda new to Struts, so please forgive these simplistic questions. (I've gone over the documentation and have been playing with the struts-example app.) 1. Is the reason bean:message key= / tags are used all over the place (for things like page titles etc) primarily for locale support? If not, then should we restrict using that for text that is used in more than 1 place (or 1 file) so that it behaves like a global replace via the config (properties) file? i.e. we shouldn't use it for things like admin.title (which would probably only be used to specify the title of the admin page), right? 2. I'm used to having a top and bottom file which get included with every file to define a page template. Is the best way to do this to use jsp:include (or c:import from JSTL) or is there a better way using some struts tag? Typically my top page has the page title so there should be a way to pass in parameters to the page. Is it better to use a custom tag in this case? Thanks for any help.

RE: some basic questions
bean:message key= / is for locale support or global replace as you wish to interpret it. Look at tiles, the struts specific include mechanism as it is quite powerful.

Orion ( http://www.orionserver.com/ ) is free for development and easy to use. It also has good support ( http://www.orionsupport.com/ , http://kb.atlassian.com/ ).

Struts
Hi,
I have a DynaValidatorForm I want to pre-populate with info from a
database. I have no problem doing this with a non-dynamic form. My code
looks like this:
DynaValidatorForm newForm = new DynaValidatorForm();
newForm.set(personNameInfo,firstname,person.getFirstName());
I have also tried:
DynaValidatorForm newForm = new DynaValidatorForm();
newForm.set(firstname,person.getFirstName());
Form name is personNameInfo, field name is firstname. I'm not sure
the difference between name/key/value. I don't know what 'name'
represents.
I store the form in the request under the key personNameInfo.
When I try the 'set' though, I get an exception:
ERROR-15:19:36,060 frontend.struts.SelectPersonAction-Error fetching
person with id=7
java.lang.NullPointerException
at
org.apache.struts.action.DynaActionForm.getDynaProperty(DynaActionForm.j
ava:551)
at
org.apache.struts.action.DynaActionForm.set(DynaActionForm.java:442)
at
com.cravenfamily.registry.frontend.struts.SelectPersonAction.secureExecu
te(SelectPersonAction.java:59)
The problem is my 'dynaClass' is null. I assume there is some kind of
init I'm supposed to be calling, but I don't know what it is. Here's the
relavent DynaActionForm code.
/**
* Return the property descriptor for the specified property name.
*
* @param name Name of the property for which to retrieve the
descriptor
*
* @exception IllegalArgumentException if this is not a valid
property
* name for our DynaClass
*/
protected DynaProperty getDynaProperty(String name) {
DynaProperty descriptor = getDynaClass().getDynaProperty(name);
-- Exception
if (descriptor == null) {
throw new IllegalArgumentException
(Invalid property name ' + name + ');
}
return (descriptor);
}
What am I missing?

Re: Pass parameter to the same JSP Display parameter value intoi/p bean field.
Here is where you can find sample apps, cleverly hidden on the home page of Struts: http://jakarta.apache.org/struts/resources/index.html But don't be shy about taking a intro public Struts training class, there are like 10 companies that train ( It used to be a few last year). Or consider a mentor/consultant, many on this list. I think you display a list of items, and users type in how many of each they want to order or something? If so: Once you master parm passing using examples above(it is so basic in Struts), bellow is an example of a multi row update. It might be more intermediate to do this. (that is why I like to teach Struts to people how know Struts) Struts basically does multi row updates for you almost transparent, trick is index tag and form bean that implements iterator (you know where the example is, right?). Rumor is that David Karr is adding docs on Index tag in a few days. Multi row updates are basis of doing master detail processing on a single page or a many to many on a single page, I give you sample working code for a simple multi row update: %@ tag lib uri=struts/html prefix=html % %@ taglib uri=struts/logic prefix=logic % %@ taglib uri=jstl/c prefix=c % html head link rel=stylesheet type=text/css href=css/default.css html:form action=/myconcreateaction?Dispatch=Save table logic:iterate name=myFormBean id=row tr tdUsername:/td tdhtml:text name=row indexed=true property=fieldName//td /tr /logic:iterate /table html:submit property=submit value=Save / /html:form /body /html hth, .V Harshal D wrote: My app (simplified) ProductSearch.jsp display a search box (searchForm) for product name -- Action - Get name string create product bean -- (AGAIN) ProductSearch.jsp display list of products bellow the search box. -- In the list display QTY from product bean but allow user to change it submit every line to GetPrice action with changed product bean (changed qty).

RE: Question about adding ActionErrors
Hi, We are validating against the database in the LoginAction through a business delegate. I think the validation in the form would be limited to checking for null or spaces... A related question. In my action, I use saveErrors. How are the 'errors' saved inside the form ? Thanks, Mohan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Sunday, December 08, 2002 1:24 AM To: Struts Users Mailing List Subject: Question about adding ActionErrors Hi, i have a LoginForm ( ValidatorForm ), which will validate if username and password is entered. Ok, but after this i have to probe if the entered username/password combination really exists in the database. My question is where to perform the database-check ... in the LoginForm by overriding the validate method or in the requested Action ( /Login.do ) ? It seems to me a litte bit confusing that a ValidatorForm should make a database-connect instead of the Action. Any help would be appreciated.
