RE: javascript and Struts

[Niesen, Nathan]

Using indexes to access page elements is not a good practice. You should
access the elements by id or through association whenever possible.

In your case, the following should be sufficient:
onchange="this.form.submit();"

If you need to do some preprocessing, I'd recommend the following pattern:

[...]
function onChangeCampaignName(aForm) {
// do preprocessing
aForm.submit();
};
[...]

[...]

Hi Guys,
i have a strange problem. Maybe you can help me. I would like to submit a
form when a select box value
has changed.Here is the code like i try it:



DatenfeldWert
Kampagnenname:






...

I also trid javascript:{document.forms[0].submit()} etc. but nothing worked.
When i try this now on
a normal HTML form it works. But with the struts form i get the message.
Method not supported by object.

But i cannot imagine why this happens, cause javascript is executed on
client side and there the code
is the same.

So do you have any idea ??

Thx in advance

I'm pretty new to the jsp tag stuff, and I need to do something that I would
think is pretty common, but I can't seem to do it without resorting to
scriptlets.
 
I have an Address, which has a String state on it.
I have a Collection of States which have an int id, and String name on them.
 
How can I generate a select list that defaults to the value that matches the
state on my Address?
 
Seems like this would be pretty common, but I can't find it anywhere :(

RE: Netscape 4.7 & disable fields

[Niesen, Nathan]

You could also have an onfocus event handler that calls blur() on the field
or sets focus to the next field. They can't change the field if they can't
put the cursor in it. This affects tabbing from field to field.

Subject:RE: Netscape 4.7 & disable fields


Potential workaround to keep those 3 ns4 users happy (actually i think
there's more like 7):

- Clicking the button sets a Javascript variable "disableTextBoxes" to true
- The textboxes have an onchange function that:
- if disableTextBoxes is false, it stores the textbox value in an array
- if disableTextBoxes is true, it changes the textbox value back to the
previous value saved in the array

So when disableTextBoxes is true, the user could edit the field value, but
as soon as the focus leaves that field it will change back to its orig
value--it's in effect uneditable.

A nice extra touch would be to have an onfocus handler in the textboxes that
calls a function tellUserIfDisabled().  tellUserIfDisabled() checks
disableTextBoxes, and if it is true, shows them an alert saying that they
shouldn't change the value in that textbox.

It's a total hack but having had to work with NS 4.7 before I got used to
doing such things...  ugh.

HTH,
Scott.

RE: OnMouseOut

[Niesen, Nathan]

I haven't used StrutsMenu so these are just suggestions:

1. Do you have JavaScript enabled?
2. Should "location=javascript:..." be "href=javascript:...", if not in the
tag at least when the html is rendered. You probably don't need the
"javascript:".
3. Is the tag rendering the html event names in all lowercase? It should be,
proper-cased event names are not supported in all browsers.
4. Have you tried with a different web browser?
5. Are you properly delimiting any nested double and single quotes?
6. Try setting onmouseout="alert('mouse out fired');"
7. Is the method you're calling returning true or false? This affects what
the browser does when you click on the link.

RE: how to switch of logging with log4j at initialization

If you put the properties files in your webapps classes dir, it will only
apply to your webapp.

Try putting the properties files in your app servers classpath. With Tomcat
you'd put them in tomcat/common/classes.

As I wrote as an answer to Edgar Dollin, my problem is not that log4j
is used, but that my log4j configuration seems to be not the only one
used, as I set the logging for "com.apache" to a file with ERROR
level, but the output for (some of?) the commons-classes is logged
anyway to stdout.

RE: [OT] JavaScript Debugger For Client-Side Validation

You guys can bash IE all you want but until about 6 months ago IE and
Netscape 4.7 were the only games in town for hard-core DTHML applications.
Being standards compliant is worthless if the standards don't contain the
features you need. Mozilla and Opera finally figured that out and started
providing some real competition. The new wave of browsers (Phoenix 0.5,
Netscape 7.0, and Opera 7.01) will finally have a shot at reducing IE's
market share. I still spend the majority of my time working around bugs and
quirks in the non-IE browsers but gap the is finally shrinking.

RE: [OT] Tiles with logic:iterate and JavaScript to sort table

[Niesen, Nathan]

Instead of hard coding the entire path, you should use the context path to
get your webapp directory and then specify the path from there.

If you had the following directory structure:

-tomcat
 -webapps
  -myWebapp
   -js
-sortTable.js

You would specify the src attribute like this: src="<%=
request.getContextPath() %>/js/sortTable.js"

The page would be renderer like this: src="/myWebapp/js/sortTable.js"

This makes the page more portable.

In my example the call to the function initTable("table0");

it is probably the JavaScript which is not called.

what is the aim of this instruction ?

the aim of alert() is to display a little popup with text inside. If it 
displays, the javascript is being executed.

if nothing is displaying, the path to the script library isn't good. Try to 
put an absolute path in your page.

Generally the JS include () should go in
the head of the document so that the objects and/or functions defined in it
will be global to the page. The alert() function just displays a dialog
window with a message. It's like using println() to debug java code.

   As the 'initFunction' function has a parameter which is the name of the 
table, its call should stay at the bottom of the page. If you put it at the 
top, there will be an error because the table hasn't been yet processed by 
the navigator so it can't know its name. To ensure the script is called, 
just put a debugging message at the first line of 'initFunction' in your 
script, such as 
 alert("function found and starting..");

RE: Configuring Tiles + Validation + Modules

[Niesen, Nathan]

Again, all that example appears to show is that you can link from one module
to another. As far as I can tell, it does not show how to define a jsp page
containing a Struts  tag in on module and then
reuse that page from modules B, C, and D. The action mappings for myAction
would need to be defined in the config files for modules B, C, and D because
the forward pages would be different.

Here's as good an example as any that I can give in this medium:

/mapping/zoomControl.jsp
...

  

  

...

/orders-module/orderTracking.jsp
...

  
  ...order selection and action controls...

...

/inventory-module/inventoryTracking.jsp
...

  ...product selection control...
  

...

/WEB-INF/struts-config-inventory-module.xml
  ...
  

  
  ...

/WEB-INF/struts-config-orders-module.xml
  ...
  

  
  ...

Subject: RE: Configuring Tiles + Validation + Modules

Nathan,

For now, I think we're going to just use the multiple config file
options (new in B3).  I was able to bust up our ONE struts-config.xml file
and get this working in just 1/2 day (it would have been less if I wouldn't
have introduced some XML syntax errors in my new config files).   In
addition, we'll probably bust up our application resource file and merge
them back together during our ANT build process.  We have a team of about 12
developers, so these files have become a real bottleneck.  This approach
seems to achieve many of the same benefits as modules, without all the
additional technical headaches (although you need to guard against duplicate
action mappings, form bean definitions, keys/values across all the
collection of files).

JOHN

I basically have the same questions. I've been searching the user docs and
mailing lists trying to get a handle on what modules were intended to do,
what modules can and can't do, and how I can use modules to improve my
application framework. It appears to me that the modules feature opened up a

whole can-o-design-worms and they're still wiggling. I can't find anything
that clearly defines intended usage of modules or the limitations of
modules; especially in regards to using "resources" outside of a modules
sub-directory.

In addition to John's questions, I have the following question:

1) How can I use tiles/templates to assemble a page in one module from
reusable "components/pages" in one or more other modules? For example: I
have pages in modules B, C, and D, that all want to pull in a menu page from

my default module as well as a reusable page from module A.

Other issues with modules:

1) Not all tags (html:img in particular) use the pagePattern or
forwardPattern attributes from the controller. If I want to use an image in
my header.jsp, the image file has to be physically located in each module or

I get a broken link.

2) The pagePattern and forwardPattern are defined on the controller which
means all tag or forward URLs for the module will be mapped to the same
context relative URL. I think it would be more flexible if you simply
specified the pattern as part of the URL attribute for the tag or forward.
For example:  and 

3) The examples don't effectively demonstrate the effects that the
contextRelative, inputForward, pagePattern, and forwardPattern attributes
have on the page, forward, action, and href attributes.

4) The examples only show how to switch from one self-contained module to
another. They don't demonstrate how to combine resources/pages from multiple

modules into a single page via either includes or tiles/templates.

Thanks, Nathan.

Subject:Configuring Tiles + Validation + Modules

I'm looking for some help on how to configure the Tiles and Validation
Plug-Ins.  A lot of the good books (Struts In Action, Programming Jakarta
Struts, etc.) and replies to the mailing list address these topics
independently, but not collectively.  In addition, I took a look at James
Holmes "Switching Modules" example, but that focuses on the different ways
to switch b/t modules, not on how to configure Modules with Tiles and the
Validation frameworks. 

For discussion purposes, let's assume I have following 3 modules (default,
modA, modB).  Here are my questions:

1) If I have a form bean definition used by all 3 modules, does it need to
be defined in each of the 3 struts-config files, or can I just declare it in
the default struts-config?

2) Does each modules' struts-config file need the following declaration to
use the Validation framework, or can I simply declare this once in the
config file for the default module?

  

  

3) For Tile Definition config files, can all of these just be declared in
the default struts-config, or should they be declared in the module
struts-config they correspond to (assuming you've divided your Tile
definitions by module)?  For example:

  

  

4) Can I use the default module's application resource file for text common
across modules?  Therefore, preventing me from having to duplicate entries
across modules.  If so, this means Struts always looks in the particular
module's application resource first, then the default module.  But this
doesn't apply for form bean definitions or action mappings, correct?

5) Is the following an acceptable way to configure the application resource
files:

 --- struts-config.xml (default) ---
 

 --- struts-config-modA.xml (default) ---
 

 --- struts-config-modB.xml (default) ---
 

Thanks in advance for your help,

JOHN

RE: Returning a different request-type (xml/pdf/doc/etc...) through Struts

[Niesen, Nathan]

We do a similar thing to return map images in gif and png format:

Action mapping (note, no forward):





MapImageAction:

  // Make sure images are not cached on client or
  // else panning/zooming will not go get a new image.
  // These values ARE case sensitive and must be exactly as below:
  response.setHeader("Pragma", "No-cache");
  response.setHeader("Cache-Control", "no-cache");
  response.setDateHeader("Expires", 1);

  response.setContentType(contentType);
  ServletOutputStream os = response.getOutputStream();
  os.write(imageBytes, 0, imageBytes.length);
  os.flush();
  os.close();

  // Do not forward this request as we have already sent the bytes back
  // to the client.
  return null;
  // I tried having a jsp page return the image bytes, but this
  // resulted in a JSP "IllegalStateException".

Subject:Returning a different request-type (xml/pdf/doc/etc...)
through Struts

I am new to struts, and have just recently began porting our current web
application over to the struts framework.  A piece of our application
involves creating a pdf file and displaying it to the user.  Currently,
in the old framework, we set the ContextType of the response, and write
the byte content to the response's oputputstream, which will render the
pdf document in the browser.  I know I have direct access to the
response under Struts, but I wanted to see if there was a better
(cleaner) implementation within the struts framework that I may utilize.

Here's a snippet of what I'm doing:
---
response.setContentLength(doc.getContent().length);
response.setContentType(doc.getMimeType().toString());
response.getOutputStream().write(doc.getContent());
return new ActionForward();
---

I've noticed that I get a NullPointer exception after the return
statement on "some" requests.  I'm really unsure of why this is
happening as well.

unwanted emty lines in produced html

[Niesen, Nathan]

IMHO, if a line only contains jsp tags, comments, or scriptlets that produce
no output then no blank line should be present in the output.

I find it especially annoying that multi-line comments generate a carriage
return for every line of the comment. Those carriage returns are part of the
comment and should be gobbled up. My guess is that this is a JSP compiler or
servlet container issue.
