RE: How Do I Create This Drop-Down List in Struts?
You should have a property in your form bean where the user selection will
go. In this case the property is name
html:select size=1 property=Property in the form bean to hold the
selection
multiple=false
html:options collection=EDITORS property=name
labelProperty=name/
/html:select

Subject: How Do I Create This Drop-Down List in Struts?
My ArrayList is a collection of bean object. The
ArrayList is created this way:
public Collection findEditors( String userrole, String
category )
{
..
EditorBean editorBean = null;
ArrayList editors = new ArrayList();
// database access code
while( rs.next() )
{
editorBean = new EditorBean(
rs.getString(user_name) );
editors.add( editorBean );
}
return editors;
...
}
and my EditorBean is like:
public class EditorBean
{
private String name;
public EditorBean() {}
public EditorBean( String name )
{
this.name = name;
}
public String getName() {
return Name;
}
public void setName( String name ) {
this.name = name;
}
}
After editors is returned, I create a session
object:
session.setAttribute( EDITORS, editors );
How do I create a drop-down list for this collection
of editors?
html:select size=1 property=??
multiple=false
html:options collection=?? property=name
labelProperty=name/
/html:select

Specifically, the issue is that a URLEncoded character like "#22530;" (堂, a building in Traditional Chinese) is modified before being written out It goes from "#22530;" to ""amp;#22530;", which then displays incorrectly in the browser. Dave, why are you URLEncoding your data before storing it in the database? If it's to filter out SQL-breaking characters, perhaps you should be using PreparedStatements instead of manually constructing a string for the SQL.

Re: How Do I Create This Drop-Down List in Struts?
The collection that you want to iterate through and the form property
aren't linked as such only when you nest the html:options tag in the
html:select tag
So your html:select form property is like any other form property, and
when submitted will only the form property will be set to only one
value from the list.
html:select property=editor
//now the list in the options tags is only really associated
//with the form property as its nested in the html:select
html:options collection=mycollection
the property attribute in the html:options tag is to drill to the
property of the bean thats exposed during the iteration and hasn't much
to do with the form itself.
..

RE: JSTL
That's right. It's important to realize that most non-trivial applications will often use more than one tag library. There is no good reason to try to restrict yourself to a single tag library. In the case of Struts, it's very beneficial to use the Struts tag library along with the JSTL. In addition, the Struts-EL contrib package (in the contrib directory) is a port of the Struts tags (the ones that aren't directly served by the JSTL), using the expression evaluation engine of the Jakarta Taglibs JSTL implementation. -Original Message- From: Tarek M.

can I avoid *.do in my URLs?
Hi, I would like to avoid having to formulate my URLs as *.do, or even /do/*. I want to have simple names like /foo and /bar, names that no single pattern could match. The reason is that I don't want to expose implementation details in my URLs, because an implementation could change and then my URLs would be no good. I care about this because I want bookmarked URLs within my application to continue to work. (See http://www.w3.org/Provider/Style/URI.html, especially the section called We used to use a cgi script for this and now we use a binary program.) I had planned to accomplish this by making multiple servlet-mapping entries in the web.xml file, one for each page, each one pointing to the controller servlet. (My application has only a small number of pages, so this seemed feasible.) But I just noticed the following warning in the User's Guide (section 5.4.2 Configure the Action Servlet Mapping): WARNING - Struts will not operate correctly if you define more than one servlet-mapping element for the controller servlet.

RE: Error while accessing the application
Just for clarification to others, your last line abbreviates the fact that in a Servlet 2.3 container, it's not necessary to include the TLDs, either in the /WEB-INF directory, or referenced in the web.xml, if you reference the canonical URI in the taglib directives in the JSP pages. The canonical URI for the tag library is listed in the TLD for the tag library. There are differences of opinion on which of these strategies is preferable. There are tradeoffs both ways. -Original Message- From: Jim Kennedy [mailto:[EMAIL PROTECTED] Hi Melanie, don't really see anything wrong right off the bat, but let's walk through what has to be configured: Place all your tlds in the WEB-INF directory (looks good here) Place all required struts library JARs in the lib directory of your web appl Configure your web.xml to include the TLDs, here's an example of one of my projects: welcome-file-list welcome-fileindex.html/welcome-file welcome-fileindex.jsp/welcome-file /welcome-file-list taglib taglib-uri/WEB-INF/c-rt.tld/taglib-uri taglib-location/WEB-INF/c-rt.tld/taglib-location /taglib taglib taglib-uri/WEB-INF/c.tld/taglib-uri taglib-location/WEB-INF/c.tld/taglib-location /taglib taglib taglib-uri/WEB-INF/fmt-rt.tld/taglib-uri taglib-location/WEB-INF/fmt-rt.tld/taglib-location /taglib taglib taglib-uri/WEB-INF/fmt.tld/taglib-uri taglib-location/WEB-INF/fmt.tld/taglib-location /taglib taglib taglib-uri/WEB-INF/struts-bean.tld/taglib-uri taglib-location/WEB-INF/struts-bean.tld/taglib-location /taglib taglib taglib-uri/WEB-INF/struts-html.tld/taglib-uri taglib-location/WEB-INF/struts-html.tld/taglib-location /taglib Finally configure the JSP to include (or point) to the proper tag definition, here's an example: %@ page import=java.util.*% [EMAIL PROTECTED] uri=/WEB-INF/c.tld prefix=c % [EMAIL PROTECTED] uri=/WEB-INF/fmt.tld prefix=fmt % [EMAIL PROTECTED] uri=/WEB-INF/struts-bean.tld prefix=bean % [EMAIL PROTECTED] uri=/WEB-INF/pager-taglib.tld prefix=pg % %@ taglib uri=/WEB-INF/security.tld prefix=security % %@ taglib uri=/WEB-INF/struts-html-el.tld prefix=html-el % I always reference tlds from the /WEB-INF directory, not from within the library JAR.

Thanks David. I get a bit worried when the idea of mixing tag libraries pops up. I've had some bad experiences with such practice. I'm not sure whether this was partly due to my lack of understanding of the libraries I used, but for example, I frequently found that beans created with the Struts bean:define tags with a page scope aren't visible to the Supported Tag Libraries Page 1.1 page tag, although as far as I understand, they should both look in the same scope.

RE: Representing Existing Objects In Forms
Toby, You could: a) Have a Password field in your ActionForm. Then, you could lookup the password, copy it into the ActionForm, and have the ActionForm display it in your JSP when you show a html:text property=password/ field. b) Save the password in a bean and print it out with a bean:write ... / statement so it is only viewable (read-only) c) use an html:text name=someRequestOrSessionBean property=password / so you could save your own bean into the request or session scope then display it as a text box. If you want it to be submitted to a form, you probably want to make sure that whatever action it submits to has a field with the same property name (in this case password).

RE: Representing Existing Objects In Forms
Toby, In your action, you can cast the ActionForm to the right type of form, then use the set/get methods. If your ActionForm is of type eg.FirstForm, in your Action's execute (or perform if you're using an older verions of Struts) you can: eg.FirstForm myForm = (eg.FirstForm) form; myForm.setPassword( someFunctionThatReturnsTheUsersPassword() ); That stores the password for display using the html:form ... / tag html:text property=password/, ASSUMING your eg.FirstForm ActionForm has a getPassword property. There should be good examples in the struts example .wars.

Regards, David -Original Message- From: Toby Saville [mailto:[EMAIL PROTECTED] Sent: Sunday, November 30, 2003 6:30 PM To: Struts Users Mailing List Subject: Representing Existing Objects In Forms hello all, I am wanting to represent an existing object using a form and was wondering how to do this. My situation is displaying a customer's details in a form for the purpose of allowing them to update them. I cant think how I can populate the form tho. Im new to struts and this list so i apolagise if this has already been answered.

It's just that a different pool came with Hibernate that I used in production by default. I'm using DBCP in testing but I always close my development computer (my desktop) down at night so I have no comments on how DBCP works in reality. I'm sure it's fine in production.

Nested tags always break
I have a situation where I can use nested:root name=ac, nested:iterate id=foo, and then *must* use nested:write name=foo property=bar, rather than omitting the name attribute. If I do, I get an exception No getter method for property foo[0].bar of bean ac. Now, this code was working fine, but I made some changes to the bean (I'm using torque). I know it's not (or at least, it shouldn't be) a problem in the beans, becuase of the fact that it works fine if I include the name attribute pointing to the id of the enclosing iterate tag. Also, why is it that I can get the struts-digest posting but can't post to the struts list? -- Rick - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Is there a way to not append jessionid with html:rewrite
Hi all, Is there a way to use html:rewrite and not have it embed the jsessionid on certain links (as with JavaScripts, images, or css style sheets which don't really work well with resources that have arbitrary strings attached to them -- that is, here's the issue: script language=JavaScript src=html:rewrite forward=image_dir /Pagination.js /script This yields, as the page is loaded, /site/assets/js/?jsessionid32543543Pagination.js or some such string -- I could create forwards for every image, js and css in the site and then have the forward just write html:rewrite forward=pagination_js / but that seems awfully hackish and clunky and just moves the bad design to the struts-cohnfig.xml, which I imagine is where it should be ifg anywhere but still, theres got to be a better way? A tag attribute, a page scope attribute, something. Any help is again appreciated, thanks, Josh - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
recursive tiles
Hi,
I have the following definition in my tiles-defs.xml:
definition name=mainTemplate path=/mainTemplate.jsp
put name=title value=${title} /
put name=header value=/components/header.jsp /
put name=menu value=/componentes/menu.jsp /
put name=body value= /
put name=footer value=/componentes/footer.jsp /
/definition
definition name=tile.foo extends=mainTemplate
put name=body value=/foo.jsp /
/definition
In mainTemplate.jsp I have:
tiles:get name=body/
What I want is to put more variable content in my foo.jsp, the same way I
put in mainTemplate.jsp
something like
foo.jsp:
tiles:get name=subBody1/
tiles:get name=subBody2/
I tried some things here, but I always get a white screen in the body
region. (and I am not forgetting taglib in the beginning of jsp file).
Tks
Felipe

Re: Error while accessing the application
Hi, I went through your recommendations. I am suspicious that iWS 6.0 web server has problem with STRUTS (Kind of bugs or unsupported versions). Do you have any information about this? Thank you!

RE: logic iterate
Are you talking about pagination? Show 3 on a page and then skip to the next page? Sounds like you want the displaytag taglib. This examples does 10 items per page: http://www.displaytag.org/example-paging.jsp Regards, David -Original Message- From: Naveen S.
