Status of validator & Struts 1.1
I checked out the struts code from CVS recently and didn't see the validator code. Is this being integrated into Struts 1.1? Or should I send feedback to David Winterfeld? -- dIon Gillard, Multitask Consulting Work: http://www.multitask.com.au JavaNews: http://www.multitask.com.au/JavaNews
Does anyone know how to get the parents BeanInfo ?
I know this a litle out of scope, but I need this info to extend the Struts existing tag. That is I want to write a tag that will print out all of the given bean properties as hidden tags inside a from. These properties includes the properties of its parent classes. appreciate your helps ...
Guide for Installing/Configuring Struts in VAJ 4.0 using WTE and WAS 4.0
Hi folks,
As promised earlier on the boards, enclose are the directions I've come up
with for installing and configuring struts to run in VAJ/WTE 4.0 and WAS 4.0.
Claim:
- I had 2 other people that I work with use these instructions, and
both where able to get up and running in under an hour.
Disclaimers:
- This work is definitely not all of my own. I am indebted to the
gracious of folks on this board who freely shared their experiences. THANKS
TO ALL OF YOU!!!
- There may be instructions here where folks disagree with my methods.
Fair enough... but if you follow these instruction you will get struts to
work. I would be more than happy to make corrections/addtions for anything
that others find work better/more correctly. In fact, I'd love it if someone
would shine more light on anything I did "incorrectly" here, as then I could
learn the "right" way to do (if there is such a thing...).
- This is my second attempt to post this, the mailer won't allow
me to post my .war file (listed in the instructions), as it says it's too
big. I'll be happy to send it directly to whoever would like it, or if
someone wants to give it a home, I'll gladly send it to them.
Lastly:
If someone wants to post this on their site for others to see, please
do so, but please add this note and leave the instructions as is.
Here to help,
Stephen :-{)

Hi Brian,
yes, you can do this. If you have a message in your
ApplicationResources file called my.test.error, you can add an error
like this:
errors.add("myTestField", new ActionError("my.test.error"));
where the string "myTestField" is the field that caused the error.
Look at the constructor for org.apache.struts.action.ActionError for
more details.

I realize this is still a bit early but what is the interest for integrating Struts/Tiles and the Jetspeed Portlet API? It's of high interest on my end. It looks like this would offer performance with a solution based upon this and background XML compilation. Take all the xml feeds, pre-compile them into html / jsp fragments, and then all this would have to happen at request time, is that the engine would assemble all the fragments that were already precompiled. Is this what you were envisioning? The things that are waiting technology-wise might be - is this a standstill until this is done?: 1 - Completed integration of struts and tiles. May be a few months? 2 - Jetspeed implementation of the Portlet-API: not been fully integrated into the main branch, and then some testing. What are your thoughts?
newbie question
Please explain these lines from struts example (index.jsp): ERROR: Application resources not loaded -- check servlet container logs for error messages. Thanks.
Re: Nesting Tags (Again)
You're almost there. The content is in your page context; the problem
is your tag doesn't declare a scripting variable. You have three choices:
1) Write a TagExtraInfo class for your eval tag that declares the
variable. Don't forget the element in your .tld!
2) Use the struts bean:define tag to declare the variable.
3) Change your code to:
<%String fullUrl="viewcontext.do?name="+pageContext.getAttribute("contextName");%>
I'd go with 2.

Julia,
I had the same problem with VAJ 3.5.3, but I presume this will work with
4.0. You need to make sure you are changing the code in the correct place.
There are two FormTag classes - one in the base taglib package and one in
the taglib.html package. In
order to get the application to work with VAJ, you need to change it in the
html package.

The problem remains, is there anything else I need do ?

RE: AW: Struts vs. JADE (from IBM) - feature and usability comparison - need help!
Two points to consider: 1. The WAS 4.0 admin tool is based on Struts 0.5, which is quite antiquated. That's not a hearty endorsement for Struts 1.0. 2. IBM is a *big* organization. The fact that the consulting group may be pushing something besides Struts while the WAS group is using Struts is not that odd. I don't know that either recommendation would be considered an endorsement of the whole company, but simply the current favorite of that group. I'm also curious to hear of other JADE experiences, since it seems to be cropping up in a number of companies all of a sudden.

The tag doesn't seem to support a way to generate the "main path" from an attribute. Is this correct? In other words, I want a link to be yadda yadda yadda, but I want the value foobar to come from an attribute in the request scope. Any ideas? Thanks.

Nesting Tags (Again)
John,
So I tried your cool eval approach but the JSP page seems to no be able to
find the string once I have placed it in the page context using the eval
tag.
Here's my implementation of the eval tag...
public class EvalBody extends BodyTagSupport {
private String id;
/* 1) At the end of the tag this function gets called. */
public int doEndTag() throws JspTagException
{
try
{ /* 2) Get the text within the tag. */
BodyContent l_tagbody = getBodyContent();
String ls_output = "";
/* 3) If text was in the tag body then process it. */
if(l_tagbody != null)
{
String ls_html_text = l_tagbody.getString();
pageContext.setAttribute(id, ls_html_text);
//this is to verify that I am setting the property...
ls_output="body text:"+ls_html_text+" id:"+id;
}
/* 4) Write the result back to output stream */
pageContext.getOut().write(ls_output.trim());
}
catch (IOException e)
{
throw new JspTagException("Tag Error:" + e.toString());
}
/* Have the JSP Container continue the JSP page as normal. */
return EVAL_PAGE;
}
public void setId(String as_id)
{
id=as_id;
}
}
here's my JSP page code...
<%String fullUrl="viewcontext.do?name="+contextName;%>
goto
context
and it fails to find the attribute on the page, here's the error...
org.apache.jasper.JasperException: Unable to compile class for
JSPC:\tc3.2.3\work\localhost_8080%2Fcontextuon\_0002fcontextmgr_0002ejsp
contextmgr_jsp_58.java:525: Undefined variable: contextName String
fullUrl="viewcontext.do?name="+contextName;
ok so it can't find the attribute even though I put it in the
pageContext...
wassup?

RE: "indexed" option does not work with html:checkbox

request object
Hi,
When forwarding from one action to another, is the same request object used? For example, is this legal?
Action subclass 1 (perform method) :
Test test = new Test();
// initialize test
request.setAttribute( "test", test )
return (mapping.findForward( "Action subclass 2" ))
Action subclass 2 (perform method):
Test newTest = (Test)request.getAttribute("test")
// try to use newly created newTest object
I seem to be getting an error when I try to do this, it will appear that the newTest Object is null.

RE: Run Struts in Entry Editon Visual Age for Java 4.0?
Sorry bother you all again
Guys,
Can you share how to run struts in VAJ4 ?. Any instructions? What
version of struts do you use ? how do you solve the XML Parser problem ?
I follow up the article of Apache Struts and VAJ part 2: Using Struts in
VAJ 3.5.3 from IBM Kyle Brown.
What I did
Import struts1.0-b2
Import struts example
Import Javax.xml.parsers.SAXParser, SAXParserFactory,
ParserConfigurationException from JAXP.jar. There is no error in soure,
but if I start to run the WTE it gives the following error.
ServletInstan X Uncaught init() exception thrown by servlet {0}: {1}
"action"
javax.servlet.ServletException:
javax.xml.parsers.FactoryConfigurationError
Either use Tomcat or WTE is fine for me, as along as I can run struts in
VAJ and debug my xxxacton or xxxform class
Thanks very much
Julia

Re: role-based Actions and page not found error
Nic,
I changed your ActionServlet (line 1573) to return SC_FORBIDDEN in the
following code block:
if (debug >= 1)
log(" Access denied to mapping for path " + path);
response.sendError(HttpServletResponse.SC_FORBIDDEN,
internal.getMessage("processAccessDenied", path));
added this to my web.xml:
403
accessDenied.jsp
And now I'm getting the error below - any ideas?

Hi Matt, All, Firstly let me apologise for my absence for the last few weeks ( I seem to end up doing this at the top of every posting I make ;) but I had a nasty and artistic bout of Food Poisoning and then a holiday to contend with. Since I have been trying to catch up on the several thousand mails that seem to have been sent whilst I was away! On to the real message though.

Yours is the first comment I have had back on this, as I think you are one of the first to look at it in any depth. Many thanks. I think you are probably right that we should return a 403 (Forbidden) as the default. I would like this to be configurable though so people can choose.

Re: Examples anyone?
Aaron, Lets go back to your second error, the "javax.servlet.ServletException: Cannot find bean task in scope null". I can simulate this if, in one of the pages where I use an iteration in this manner, I remove or modify the tag definition. Are you absolutely sure that you have the <%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %> tag definition in your page? and that the prefix "logic" is the same in the tag definition? This would account for "workman" being printed only once and getting a null pointer when you refered to the "task" iteration id.

Re: Tabs on JSPs
Struts is a server-side framework, and doesn't address these types of client-side issues. But whatever would work without Struts in this regard, should work the same with Struts. I can't recommend anything off-hand, but any JSP GUI framework that did these things would probably work well with Struts. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel +1 716 737-3463 -- http://www.husted.com/about/struts/ [EMAIL PROTECTED] wrote: > > Hello! > > I'm new to struts, JSP, VAJ, etc. > > Is there any way to simulate the appearance of GUI tabs on a web page using > struts? > > I know I can do it with frames, javaScript and layering ... but I'm hoping I > won't have to get into that. > > I searched the struts-user archive for this and found very little. > > Thanks in advance > > Allan
Re: Tabs on JSPs
JSP's only create HTML - when it gets to the browser it's the same as if you wrote it statically. Therefore, tabs would be created the same way you would on a static HTML page.

Hello! I'm new to struts, JSP, VAJ, etc. Is there any way to simulate the appearance of GUI tabs on a web page using struts? I know I can do it with frames, javaScript and layering ... but I'm hoping I won't have to get into that. I searched the struts-user archive for this and found very little. Thanks in advance Allan

role-based Actions and page not found error
Nic, I think the best thing to handle the situation below would be to direct the user to a return a 403 error (forbidden). Then in the web.xml, it might be possible to direct your server to route 403 errors to a specific page. Is there anywhere that you specify returning a 404 error? This is a comment to the following message at: http://husted.com/about/struts/struts-security.htm But what happens when the user is found to not be in the correct role? At the moment the user just gets a page not found at the browser level which is good in one way in that if a user went to the URL directly they wouldn't know if the URL is correct or not but we may want it to go to a specific (configurable) 'illegal access' page or something similar.

I'm in the middle of working out a design for portal-like applications using Tiles and the very cool RSS Channel bean from the Commons-Digester. I'd love to add personalization to this as well. While keeping this in a database is a good option, Jetspeed creates a folder for each user and stores the configurations there in XML. So that's something to think about too. I'm looking at Sixbs by Tagtraum (http://www.tagtraum.com/sixbs.html) to store user configurations this way.

Re: Personalisation Best Practice
Watch out for browser caching issues with a JSP stylesheet. It may be slow
to adopt new preferences because the browser is using a cached copy. Turning
caching off might hurt the performance of both the server (having to
regenerate the stylesheet for each page view) and browser (having to
download the stylesheet for each page view).
Perhaps you could keep track of when the preferences change (e.g. save the
current time in millis as a bean attribute) and pass that on the query
string to the stylesheet JSP. The stylesheet JSP would totally ignore the
parameter, but the browser would know when it needs to get a new copy of the
stylesheet because the query string would be different.
So, if you used:
To the browser, the URL would be:
stylesheet.jsp?u=67463286042323 - never seen this URL before, make request
stylesheet.jsp?u=67463286042323 - use cached copy

Re: DataBase Controller in Struts
Bruno, regarding the features you speak of, one of Struts most enthusiastic user groups is the Expresso community, a framework which has adopted the lightweight Struts framework within it's more heavyweight, database centric approach. Expresso has many of the features you have mentioned needing, and many more as well. As a community, it is neither as large or as well documented as the Struts community, but I have been using it for a year and it is pretty cool, It is so cool, in fact, that many people dismiss it as simply being too good to be true, which is unfortunate for those of us who use it every day, and would enjoy a deeper corporate user base. The Struts integration into Expresso is still on a .ea release, so it may be a few more weeks before you consider it production ready in this form. http://jcorporate.com is where you learn more about it.

Re: Personalisation Best Practice
Hi Peter,
I think you might have trouble with having too many JSP tags in the page if
you employed a scheme like that. Yes, it seems a little crazy, but we have
had trouble when a page has many JSP tags (Struts or otherwise) in it. The
server would throw a cryptic exception - class verify error or something
like that. But there are some alternatives...
One alternative that would be really easy to implement is to create a couple
of different style sheets; one for each of the different color schemes (or
"themes") you wanted to support. Then you could just store a single
preference value (the name of the style sheet) and use that to select one of
the style sheets.
STYLE SHEETS (3 different files):
=
apple-theme.css
---
tr.datarow { background: #00FF00 }
orange-theme.css
tr.datarow { background: #FF9900 }
seablue-theme.css
-
tr.datarow { background: #0066CC }
JSP PAGE:
=
"
type="text/css">
...
So, that would be easy to do but would allow the user only to select a whole
"theme" rather than choosing colors for individual elements. I suspect that
more flexibility could be afforded by having more style sheets to represent
more combinations, or it seems likely to me that there is some CSS facility
that would help support such fine-grained preferences. I am not a CSS
expert, so I don't have any specific suggestions there.
Ultimately, I think you want to have named styles hardcoded into the HTML
tags and then dynamically select (by choosing which style sheet(s) to link
to, etc.) what attribute values get associated with those style names (e.g.
the name "datarow" could have a green, orange, or blue background depending
on the user's preference). This strategy also has the nice feature of
letting you postpone the implementation of personalization until you have
time to do it. With those future plans in mind, however, it would seem wise
to choose style names that represent the meaning of the style (e.g.
"altrow") rather than a particular style attribute value itself (e.g.
"lightgrayrow").
Stuff that isn't so great about my example:
- I didn't try it, so it might need tweaking -- in particular, the quoting
might be faulty (we had some messages on that today)
- You might want to store a symbolic name rather than the CSS filename
itself as the preference value, or at least avoid storing the context path
with the name in the database. For example, you might construct the name
like this:
linkHREF = request.getContextPath() + "/styles/" + storedPrefValue +
".css";
which might evaluate to something like:
/myApp/styles/apple-theme.css
Using a bean to store this value in the session (as opposed to just storing
the preference value itself) is probably a good idea if you wish to switch
to a more complicated scheme in the future. That way, you can add bean
attributes without disrupting the code that manages the bean itself.
Creating your own custom tag to write out the tag(s) could be a
useful technique as well. Initially, you might just have the tag write out a
tag with a hardcoded href value. Then, if you implement theme-based
personalization, you can rewrite the tag to look for the prefs bean in the
session and transform the attribute into an href value for the (which
also avoids duplication of the transform code). And eventually, you might
need to write out several and/or

Re: DataBase Controller in Struts
In general, you would might want to write a helper class to handle the
database access. Struts doesn't need to know where the data comes from
or goes to. This isn't easy to do with the GenericDataSource in the
Struts package, since it is tied to the Servletcontext, so I use PoolMan
(www.codestudio.com) instead.
Basically, I might have a method like
Data.articleUpdate(thisForm.get("article"),
thisForm.get("contributor"),
thisForm.get("creator"),
thisForm.get("title"),
thisForm.get("content")
);
Where Data is a helper with no links to the HTTP layer that handles all
the data access. This is the most the Action sees regarding data access.
For larger datasets, I might have a method on Data that takes a Map, and
retrieves the properties that way. Most of my objects can create Maps of
themselves these days, since that plays well with BeanUtils.populate().
Another way to go might be to create a bean that represented the
ResultSet (or equivalent), which you could populate and pass to a helper
calss.
To attach to the database, I use another helper method that returns the
connection to Data (so that class doesn't actually know where the
resource layer is either).
public final class ConnectionPool {
/**
* An exception message to throw if datasource is null.
*/
public static final String DATASOURCE_ERROR = "Connection pool " +
"not available. Check your poolman.xml config, and be sure " +
" you are using a valid dbname parameter (use dbname, not
jndiName)";
/**
* The application scope attribute under which our JNDI datasource
* context is stored.
*/
public static final String JNDI_CONTEXT_KEY = "java:comp/env";
/**
* The application scope attribute under which our JNDI datasource
* is stored.
*/
// public static final String JNDI_DATASOURCE_KEY = "jdbc/artimus";
public static final String JNDI_DATASOURCE_KEY = "artimus";
/**
* The application scope JNDI path under which our datasource
* is stored.
*/
public static final String JNDI_NAME_KEY =
"java:comp/env/jdbc/artimus";
/**
* Returns a JDBC connection from a connection pool or other
* resource, to be used and closed promptly.
*
* @returns JDBC connection from resource layer.
* @exception SQLException on SQL or other errors. May wrap other
* exceptions depending on implementation. Will not return null.
*/
public static final Connection getConnection() throws SQLException {
DataSource ds = PoolMan.findDataSource(JNDI_DATASOURCE_KEY);
if (ds==null)
throw new SQLException(DATASOURCE_ERROR);
return(ds.getConnection());
}
}
On the return trip, I use a BeanUtils.populate() derivative to move the
ResultSet into an arbitrary bean or collection of beans. These could be
ActionForm beans or any other. The method doesn't care. See
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg14397.html
for more on that.

Personalisation Best Practice
What is a good way of using Struts and personalisation ?
I would like to write a JavaBean with some personalisation getter and setter.
It would probably pick up the details from the database
I would like to write method to change the background colours of table rows
for example in a trading application in conjunction with HTML
Cascading Style Sheet. Suppose I have in my external CSS
.tr-apple: { background: #00FF00 }
.tr-orange:{ background: #FF9900 }
.tr-seablue: { background: #0066CC }
In the my JSP I could have a StyleBean
class StyleBean { ...
String tr_bgcolor = "tr-apple"; // DEFAULT setting
String getTableRowBackgroundHTML() {
return "background=\""+tr_bgcolor+"\" ";
}
String setTableRowBackground( String htmlColor ) {
this.tr_bgcolor = htmlColor;
}
... }

RE: state dependent look&feel of HTML elements in struts/JSP
Title: RE: state dependent look&feel of HTML elements in struts/JSP i think you can do this by using à bean in wich you use somes attributes to describe the state of your JSP. Then , you test the values of this bean in your JSP to make conditional section. Struts Tags allow this kind of things. A+ Cédric -Message d'origine- De : Roland Berger [mailto:[EMAIL PROTECTED]] Envoyé : vendredi 7 septembre 2001 02:44 À : Struts Mailinglist Objet : state dependent look&feel of HTML elements in struts/JSP Hi all Offten one need severel JSP pages which looks almost the same. The only difference could be that a field in one page is visible in the other not or a link is activ in one page not in the other. Since I don't wont to write two different JSP pages with that little difference I wonder if there is a mechanism or framework which can do that for me. Example: Assumed I have a button which is activ in one JSP page which has to be set to inactiv because the state of the datamodel (or whatever) has changed. One solution would be to write a tag that checks the state of the datamodel and set's the property of the button either to activ or inactiv. Now it would be very nice if there is a framework where I can store the state (activ/inactiv, visible/invisible, colors, etc.) of any HTML Element (Buttons, Links, etc). Whenever I have to display the same JSP page the HTML Element should check itself if his own state is activ/inactiv, visible/invisible, blue/green . The state of a HTML Element could be stored in an Object or even stored to a database. Does somebody know procedures, tag libraries, framework which simplifies creation of state dependent look&feel HTML Element's. Since I'm quite new to JSP this might be a stupid question. If it is, plese answer anyway. Kind regards Roland Berger

DataBase Controller in Struts
Hi all, I'm new to J2EE application design. I would like to get advices on how to best get access to DB in struts&J2EE applications (through datasource). I don't want to code JDBC access in all struts action classes that need to access database. What would be the best way to access database ? Would it be possible from action classes to give control to a DataBase Controller that would be in charge of accessing database ? How does this controller may look like ?

hello, the stange thing is, when i get the bean with useBean then i can access all elements and put them out. no problems perform. then i put my iterate tag to the jsp. when i debug the jsp i can see that the bean is correctly in the scope and CAN BE ACCESSED! the iterator runs ONCE trought the bean writes and then the scope of the bean is suddenly lost. then i get my meaningful jsp - exception. what could be the problem??? there should be no startup mistake. thanks juraj -Ursprüngliche Nachricht- Von:juraj Lenharcik Gesendet: Donnerstag, 6.

Off-topic: JSP documents (Was: nesting tags)
This raises an interesting question. "JSP documents", the XML verion of JSP, is defined in JSP spec 1.2 (Let's call them xJSP.) I think Tomcat 4.0 implements it. In xJSP, expressions like <%= blah %> are represented as blah So, does a JSP 1.2 compliant JSP container handles an xJSP containing something like: which is equivalent to this in normal JSP: Or, is there a different approach to acheive the same effect? -- John At 12:08 pm 05-09-2001 -0700, you wrote: Everyone wants to do this.
