Custom types and select lists

[Lance Hill]

I  am trying to find an example of how to populate a select list of objects,
show the correct item as selected, and if the selection is saved, properly
update the object containing the item. In the example below, I would want to
show a group of fields for Student information with a select list of
Campuses. If the Student is already stored with a specific Campus, that
should be selected. If the selection choice is changed, saving the Student
should update what Campus object is contained by the Student.

 

I have a custom TypeConverter  to convert between the Campus id string and
Campus objects and I can see the conversion code executes fine.
Unfortunately, saving a selection results in an "invalid field value for
field 'campus'" error and when I first call up the page, the selected Campus
is not the correct one.

 

 

public class Student {

 

  private Campus campus;

  

  public Campus getCampus() {return campus; }

  public void setCampus(Campus campus) {this.campus = campus; }

}

 

public class Campus {

 

  private Long id;

private String name;

  

  public Long getId() {return name; }

  public void setId(Long id) {this.id = id; )

  public String getName() {return name; }

  public void setName(String name) {this.name = name; }

}

 

public class StudentAction extends ActionSupport implements ModelDriven,
Preparable {

 

protected Object model;

private Student student;

  private Campus campus;

private List campusList; 

  private DB db;

  private long id;

 

  public void prepare() throws Exception {   

campusList = db.findAllCampuses();

if (getId() == 0) {

student = db.createNewStudent(); 

} else { 

student = db.findByStudentId(getId()); 

} 

  }

 

  public String save() {

  try {

  db.save(getModel());

} catch (Exception e) {

  return ERROR;

}

  return SUCCESS;

}

  public Student getModel() {return student; }

public long getId() {return id; }

public void getId() {return id; }

 

}

 

public class CampusConverter extends StrutsTypeConverter {

  

private DB db;

  

  public Object convertFromString(Map context, String[] values, Class
toClass) {

  Campus campus = null;

if (values != null && values.length > 0 && values[0] != null &&
values[0].length() > 0) {

campus = db.findCampusById(new Long(values[0]));

}

return campus;

  }

  public String convertToString(Map context, Object o) {

if (o instanceof Campus) {

return ((Campus)o).getId().toString();

}

return "";

  }

}

 



  







  



 

Suggestions, corrections, pointers, or links to examples/tutorials of how to
do this properly would be greatly appreciated.

SecurityContextHolder.getContext().getAuthentication() returning null

[Lance Hill]

I am trying to get access to the currently logged in user, but when I call
SecurityContextHolder.getContext().getAuthentication(), the Authentication
returned is null. I am assuming the user is logged in since they have access
to the secure page I am testing, but I don't know how to tell for sure since
I cannot access the Authentication object.

 

Any hints about why SecurityContextHolder.getContext().getAuthentication()
would return a null?

I used the same method to obtain the Authentication, but it returns as null.
The user is logged in since it gets to the protected page I am accessing.
Any thoughts on how to get the properly populated SecurityContext?

I use -

I assume that if the object returned is null, then the user isn't logged in.

I am using spring-security 2.0.4.

RE: Getting the authenticated user from Spring Security for use in an Action

[Lance Hill]

I have Spring Security set up to use CasAutheticationProvider to provide a
UserDetails object. 

I did find an example that uses the SecurityContext to obtain an
Authentication object and grab the UserDetails from there. I am not sure how
to get access to the populated SecurityContext since
SecurityContextHolder.getContext() is returning an empty SecurityContext and
I am not sure if that is the best way to access the user.

Struts + Spring 3

[Lance Hill]

I am currently working on a project that uses maven, struts 2, spring, and
spring security and ran into a big headache when trying to use spring
security 3.

 

Does anyone have an example of a working application that uses Spring 3
together with Struts 2? The reason I ask is that I was using the
struts-spring-plugin 2.1.8 and when I started to implement spring security,
I used version 3 which requires spring version 3, but the plugin relies on
spring 2.5.6.

 

Thank you,

Lance Hill

Single Sign On And Spring Security

[Lance Hill]

Hello,

 

I am hoping someone can provide me with some links or examples of how to
combine Struts 2 with Spring security. The end goal is to use Spring
security to access a CAS server (http://www.jasig.org/cas) in order to
provide single sign on ability between a Struts2 application and a Wordpress
site.

 

Thank you,

Lance Hill

 

Old tiles site

I had been using this as a reference until I discovered it was out of date

It would have been nice if the old site had told me this first thing.

Using tiles 2 with struts 1

Is it possible to use tiles2 with struts1?
I am about to move a struts 1 app to spring MVC + tiles2. I was hoping that
spring MVC and struts 1 could live side by side in the interum period but

Re: Multiple upload using Struts 1.0

You should be right if you implement the 4 indexed bean methods on your 
form.
@see 
http://java.sun.com/j2se/1.4.2/docs/api/java/beans/IndexedPropertyDescriptor.html#IndexedPropertyDescriptor(java.lang.String,

Here is an example if your property holding the files is called "files"

jsp:
 
 
 


form:
public class MyMultiFileForm {
   private List files = new ArrayList();

   // provide implementations for the following methods
   public List getFiles()
   public List setFiles()
   public FormFile getFiles(int index)
   public void setFiles(int index, FormFile file)
}

All pages inside the same form, last page submits.

Re: JSP pre-compile question

[Lance]

It sounds like it's a non-struts issue to me.

Try putting the following in the jsp after you draw the form
<% response.getWriter().flush(); %>

If it comes thru quickly there's something after you write the form 
that's holding the page up.
You might need some println's with times or a debugger etc to see what's 
going on.


> it's as if the page is being streamed line by line, from top to bottom.
This depends on the app server but it could be byte by byte (via 
response.getOutputStream())

Hi guys...Thanks for all your help so far, but to answer your

The slowness in rendering the page is very obvious...it's as if the page

There are no images on the page...

The page consists of 5 form fields...

The request does not access any DB...

The HTML outputted is only 17KB...

I am running it locally on Weblogic 9.2 and Java 5...

I doubt it's a pre-compile issue now because the slowness and

first...

Any other ideas???

This might also be because you are not specifying heights (and widths)

If you have any other static widths & heights (menu area, header area

The short answer is no because this is how the browser receives the

about the page, and pretty much all browsers display the data as soon


as
  

they can after get it.

There are things you can do to reduce the visibility of this to the

(smaller tables and div areas, smaller pages, etc.), but there isn't
anything you can do about how the browser receives the data and

The short answer is no because this is how the browser receives the data
about the page, and pretty much all browsers display the data as soon as
they can after get it.

There are things you can do to reduce the visibility of this to the user
(smaller tables and div areas, smaller pages, etc.), but there isn't
anything you can do about how the browser receives the data and chooses to
render it.

Hi,

I am evaluating Struts 2.0, and I'm using tiles pluging with it...

 


When my pages render in the browser, they seem to render top down, with a
slight delay in rendering...meaning the top of the page renders first, then
the rest of the page renders gradually, until you see the full page...Is
there a way to change this and have it render without the delay???

 


Thanks,
Charbel

Hi Lance, as already established (see previous posts), it is not a 
matter of regular expressions.

The matter is: the variable in the Action is a Long (and MUST be a Long).
The regex validation does not work, if the variable is not a String.
I'm searching a way to validate (through Action-validation.xml) a 
field that must be numeric, and that is defined as a Long in the 
action corresponding to the Form. According to this, field-validator 
type="int" is inadequate, and I was not able to found a number (or 
Long?) validation.

Thank for the reply, Dave. I switched to regex because I wanted to 
validate a field to be a number, but in the docs I found only 
type="int" validation while I need a wider range. So how to validate a 
Long value? I'm pretty sure it's possible...


Thanks again.

Re: How can I access an attribute of session using JSP tags?

I am saying the standard struts tags do check session scope if 
scope="session" or no scope is provided, so it's probably a bug in your

Re: How can I access an attribute of session using JSP tags?

[Lance]

It should be ok, if you leave the scope attribute empty, all scopes will 
be checked.

If scope="session" the tags will only check session scope.

Can I also suggest checking jstl which may make things (esp logic) a lot 
easier

Re: [s2] Best method of passing ActionErrors through a redirect

[Lance]

You could forward rather than redirect.
Another option is to use "flash scope" which has been discussed on this 
list previously. My understanding of this is that a filter manages a map 
on the session and requests have access to attributes added by the 
previous request.


I have never implemented the latter but it sounds kinda cool.

Subject: [s2] Best method of passing ActionErrors through a redirect

Simple question; 
 
Is there any way to retain messages added with addActionError or

addActionMessage during a redirect?
 
 
 
More complex explanation of my setup;
 
ActionA gets data and has uses a jsp to display the data (using
my_jsp.jsp). 
my_jsp.jsp has a comment field which submits data to ActionB

ActionB processes the comment and then should send the user to ActionA
which
gets the data with the new comment and re-displays the jsp.
 
To go from ActionB to ActionA I use a redirect, but the redirect seems

to
cause anything added with addActionError or addActionMessage to get
dropped
and so the jsp doesn't display them.
 
 
Any suggestions on what to do?

Re: Struts2 DWR parameter issue

You could use jsp tags to create a hidden template row.
Client side you can clone the template row using dwr.util.cloneNode() 
then tweak the appropriate bits.

Re: OOM Error (Java heap space) from 1800+ form elements, am I doing something wrong?

[Lance]

Firstly, I hope you are only using "request" scope for these forms. 
Session scope would kill your application.
Have you tried experimenting with the JVM options? 
(http://blogs.sun.com/watt/resource/jvm-options-list.html)
In particular -Xms (initial Java heap size) and -Xmx (maximum Java heap 
size)

If using jboss, you will need to edit run.bat (PC) or run.conf (unix)

eg
set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m

Forsberg, Mike wrote:

A form of approximately 1800 form elements is causing
"java.lang.OutOfMemoryError: Java heap space".  When 1000 form elements

The environment:
- JBoss 4.0.5
- Struts 1.1
- A jsp page using struts  tags to start and end the form
block.  Then insidethe form, xslt is used to parse a 300 element xml
document into 6 input tags per element.

What seems to be happening, the reset method for the form bean is
called. Then before any set methods are called, the OOME is thrown.

Should I throw out (REALLY DON'T WANT TO) the xslt and use nested form

Any help would be appreciated.

Re: session is not destroyed

HttpSession.invalidate() will remove all attributes from the session and 
consequent calls to getAttribute() on an invalidated session will cause 
an IllegalStateException.
It could be that an attribute with the same name is in another scope

pageContext.findAttribute() somewhere.


Can you send through some code?

java.util.Set does not guarantee that the order of it's elements remain

Use a List or an array in the web tier and perhaps convert to a set in

Re: Dynamic back button

[Lance]

There are a couple of tricks
1. The referring page can be found in request.getHeader("referer")... 
the referring page's request parameters can not be found though so this 
will probably not work.


2. You can implement a javax.servlet.Filter
This pushes and pops pages (and their parameters) to a stack.
Pop occurs when back is clicked
When the user chooses an option from the main menu, you clear the stack
Back button (tag??) uses stack.peek(1) to get the prev page and it's 
parameters.

I have no idea y its happening like this. Can any one help me with this?

Sounds like a classpath issue to me.
Try searching your webapp for multiple struts.jar or 
commons-fileupload.jar. Are they both in the same dir? (WEB-INF/lib 
probably)

Re: Response already committed

[Lance]

I just re-read your email... pls ignore my last reply.
My s2 knowlege is very minimal but chances are that an ajax action is 
triggered by an XmlHttpRequest. In this case, you don't want to redirect 
this request. What you want to do is send something (javascript) back  
to the calling page telling it to redirect itself. I'm sure one of the 
s2 users out there have some suggestions here.

The response is considered committed once you have written to the 
outputstream (perhaps in a jsp).

Once a response has been comitted, you can not redirect or forward etc.

The best solution is to redirect before you write anything to the output

stream, sometimes this is not possible.
Another slightly dodgy solution (I have used this) is to write a 
script tag to the outputstream.

It don't always work because it reset to the values that were

The case it don't work is when you make a change on a form, post it 
and there was errors. The form is loaded again with the wrong values 
you previously typed and an error message. If you push a "reset

The only way is to use an action for this.

Re: Somewhat OT: Forward to JSP in JAR file

[Lance]

I was doing this sort of dodgy thing at one stage, dynamically writing 
jsp's to the filesystem


To get the real path of the webroot you can use the following code:
String webroot = pageContext.getServletContext().getRealPath("/");
if (!webroot.endsWith("/")) {
  webroot += '/';
}

From memory this worked on jboss on windows but I think I came across 
problems when testing on weblogic or websphere (can't remember) on unix.
I was not allowed to write to the filesystem, i didn't resolve the issue 
which could have been down to file permissions, I ended up abandoning 
what I was doing.


Richard Wallace wrote:

Do you have anything on the forwarding to a JSP in a JAR file that you

that jsps are contained in to the filter I could access it that way.
That sort of works.  What I wind up getting is the unparsed JSP.  So,
I was thinking that I could instead extract the JSP I'm trying to get
to the filesystem and forward to that, but that seems messy.

Did you find a good way to accomplish this?

Re: S2: Disable datetimepicker

I'm not a struts2 user (unfortunately) but this seems bad to me. From 
what I see of the s2 tags, they abstract you from the fact that dojo is

Should struts2 have it's own core js that proxies through to the dojo 
implementation?

Re: Load an .xml file when server start up

You could implement a javax.servlet.ServletContextListener that is

Maybe the PlugIn interface can provide what you want.
It's notified just before and after the application life cycle. 
http://struts.apache.org/1.3.8/apidocs/index.html

Also, you should configure to load ActionServlet when server starts up
in web.xml, so that the your plugin will be invoked before that.

Good luck.

Re: How to get original query string after more than two forwards

[Lance]

Oh, and another thing, it looks like your action is redirecting to your 
jsp instead of forwarding. In struts config, remove the redirect="true" 
from your forward. With redirect = true, any request attributes you set 
in your action will not make it to your jsp, also request scoped forms 
won't work. By changing this, request.getQueryString()  will work as you 
expect in your jsp so you may not need a filter after all.

Re: How to make a SELECT list readonly? If set disabled, loses the value when submit.

[Lance]

Another option is to make a disabled style in your css and blur onfocus


:


Using a hidden element with the same name is slightly dodgy in that 
form.elements["id"] will return a different value depending if the 
hidden element is placed before or after the select.

Re: Map-backed forms in Struts2

[Lance]

Do you have a getValue(String key) method?
I am not a s2 user but I have read the OGNL spec so sorry if I'm wrong 
but OGNL needs

  public PropertyType getPropertyName(IndexType index)
  and public void setPropertyName(IndexType index, PropertyType value)

http://www.ognl.org/2.6.9/Documentation/html/LanguageGuide/indexing.html#N10189

Hi all,

A system I am developing requires forms to be generated dynamically at
runtime based on data stored in a database. I have read that it is possible
to use map-backed forms in Struts1 to achieve this using something of the
form '' where the
associated Action class has a method of the form 'public void
setValue(String key, Object value)', resulting in name-value pairs being
submitted to the Action class.

Is this possible to achieve in Struts2? I have not been able to make it
work. When I use the above expression for the name attribute the setValue
method is never called (I have checked this with a few debug print
statements), but no exception is thrown either. It just appears that
nothing happens.

Is this something I am doing wrong, or is there some other way to do this
in Struts2, or is it a bug?

I am using Struts 2.0.6 with Java 1.5.3, Tomcat 5.5 and Internet Explorer
6.

Thanks a lot in advance,

James

Re: Form data to Vector

[Lance]

ok, i hadn't realised you were a newb.
yes, vector is on your form... i'd use an ArrayList tho (Vector is 
synchronized = slower)


eg
public ActionForward execute(ActionMapping mapping, ActionForm f, 
javax.servlet.http.HttpServletRequest request, 
javax.servlet.http.HttpServletResponse response)  {

   MyForm form = (MyForm) f;

  if ("add".equals(mapping.getParameter()) {
  form.getVector().add(new Record());
  } else if ("save".equals(mapping.getParameter()) {
  saveRecords(form.getVector());
  }
}

try searching the web for struts CRUD examples / tutorials.

Balazs Michnay wrote:

OK, we're getting closer and closer to the solution... :)
It seems that only the first options works for me, because the data are held by two 
 controls that are created dynamically and are populated from the 
db. So when you click on the first one, the form is submitted by a Javascript 
function so that the second one can be populated with db data.

Yes, I have two different .do actions for each submit button.

  

Your add action adds an empty row to your vector then goes back to the page,
JSP magically draws the empty record.
  


OK, now I completely understand the logic, I just don't see how it can be 
implemented.
I really need to know where the vector should be stored (form bean?) and how 
exactly I can add an element to it (create a method in the form bean class to 
add elements?).
You say, that elements should be added in the action class, but how can I 
reference a bean method that performs the actual adding? I couldn't figure it 
out...
Of course, when you press the submit button (not the add button) all the 
previously added elements must be available...

I hope my goal is clear for you,

Thanks a lot,

MB

In your load() action, you hit the db and generate some object for each 
row and put them into your vector.
Your jsp loops over all of the objects in the vector and displays 
s for each object (row)


Sometimes, you may generate a row without a serverside call (javascript) 
then post the form. In this case the set(index, object) of your vector 
will cause an IndexOutOfBoundsException. For this case, I use a LazyList 
and a factory which creates an empty object at the new index, then 
struts can populate the object with the  values.

Looks ok to me altho im not familiar with parse position

You might wanna allow blank too
   if (price != null && price.trim().length() != 0) {

And catch NumberFormatException / set an error

And setPriceDouble(null) in your forms reset() method

Peter Neu wrote:

OK so what I did is:

-> Value gets displayed with commas. 


--action-form-

NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.GERMAN);
DecimalFormat df = (DecimalFormat) nf;
df.setDecimalSeparatorAlwaysShown(false);
df.applyPattern("#,###,###,###,###.#");


if (price != null) {
if (price.contains(".")) {
ActionError msg = new
ActionError("servlets.jsp.error.edit1");

Number inNbr = df.parse(price, pp2);
setPriceDouble(inNbr.doubleValue());
}
}

In my struts action form I check for null values and the copy the string

Does that make sense?

Your brute force approach does not use  tho?
Also, I have a suspicion that struts will either throw an exception or
set nulls for inputted numbers that contain commas, you might need to
use Strings on your form and format / parse to numbers in your action(s).

Re: AW: AW: HowTo Format Numbers in html:text tag?

[Lance]

Your brute force approach does not use  tho?
Also, I have a suspicion that struts will either throw an exception or 
set nulls for inputted numbers that contain commas, you might need to 
use Strings on your form and format / parse to numbers in your action(s).

[S1] Validating spoofed fields

[Lance]

I want to validate user input to check for spoofed fields eg. a spoofing 
a value that was not in a select menu or a radio group etc. I'm thinking 
of doing this by:


Extending  to create a FormOptions object that represents the 
input names and options. It will also put a hidden formId field on the page.
Extending , ,  to add to the 
FormOptions object
Extend RequestProcessor or have a filter that uses the formId to look up 
the FormOptions object for the current POST and validate the request 
parameters against it.


Has anyone already solved this problem / have a different suggestion?

Cheers,
Lance.

Re: Filtering multipart content

[Lance]

My filter is only interested in text parameters, my struts action 
processes the file parameter. If I parse the request myself (in the 
filter), the file parameter does not make it through to my action. If I 
do not parse the request myself, I can not see the parameters in my filter.


Hope this clears things up a bit.

trad-ex wrote:

Hi Lance,

Sorry for my misunderstanding your issue.
What I understood is:

 Your Filter class works fine except file parameter.
 
Is this correct ?

So, after I looked over your implementation, I found the line below:

parameterMap = multipartHandler.getTextElements();

So, parameterMap has only "normal text parameters" (you called), doesn't 
it ?


Why doesn't you adopt "getAllElements()" ?
But I don't have tested it yet, but if my guess above is right, it does 
work.

Hi trad-ex,
In action code, the ActionServlet has already parsed the request for you 
so request.getParameterMap() magically works. In a filter scenario, the 
request has not yet been parsed. I have since abondened attempting to 
filter multipart requests in my filter. Luckily most of our actions 
extend a common BaseAction and I was able to plug the filtering logic in 
there. It would have been nice to do it in a filter. I'm still 
interested if someone else has an answer.

   Map parameterMap;
   if (isMultipart) {

Re: auto-refreshing stock price

You could use DWR's reverse ajax which allows the server to push data to 
clients rather than the clients polling which can be inefficient.

I'm not that familiar with the nested tags - are you saying that you
have pages that used these tags and worked in Struts 1.2.x and they no
longer do so when upgrading to Struts 1.3.5?

I want record.getInvestor().getName() to be called. My understanding of nested 
is that  does not need to mention "record" as it implicitly

We are in the process of upgrading to struts 1.3.5, I have followed the
upgrade guide at http://wiki.apache.org/struts/StrutsUpgradeNotes12to13.
Most of the nested tags now seem to be broken.

For example:

  

  


The following exception is thrown:
javax.servlet.jsp.JspException: No getter method for property:
"investor.name" of bean: "someForm"
at org.apache.struts.taglib.TagUtils.lookup(TagUtils.java:903)

at
org.apache.struts.taglib.nested.bean.NestedWriteTag.doStartTag(NestedWriteTa
g.java:60)


It seems as if  is going to the  to get
"investor.name" instead of "record" in  as I would expect.
If I change my  tags to  it fixes
them. I have looked at the code and writeNesting uses
NestedPropertyHelper.getAdjustedProperty() whereas write uses
NestedPropertyHelper.setNestedProperties().

 is broken too, looking at the similarities in all of the
nested tags I get the they're all broken in this way.

[Lance Semmens]

We are in the process of upgrading to struts 1.3.5, I have followed the upgrade 
guide at http://wiki.apache.org/struts/StrutsUpgradeNotes12to13. Most of the 
nested tags now seem to be broken.

For example:

  

  


The following exception is thrown:
javax.servlet.jsp.JspException: No getter method for property: "investor.name" 
of bean: "someForm"
at org.apache.struts.taglib.TagUtils.lookup(TagUtils.java:903)
at org.apache.struts.taglib.bean.WriteTag.doStartTag(WriteTag.java:230)
at 
org.apache.struts.taglib.nested.bean.NestedWriteTag.doStartTag(NestedWriteTag.java:60)


It seems as if  is going to the  to get 
"investor.name" instead of "record" in  as I would expect. If 
I change my  tags to  it fixes them. I 
have looked at the code and writeNesting uses 
NestedPropertyHelper.getAdjustedProperty() whereas write uses 
NestedPropertyHelper.setNestedProperties().

 is broken too, looking at the similarities in all of the 
nested tags I get the they're all broken in this way. 

Cheers,
Lance.

RE: Logging to db

[Lance Semmens]

It would be easy enough to do by writing a custom javax.servlet.Filter. You 
would map your Filter to "*.do" in web.xml.

Alternatively you could configure a JDBC appender in log4j for 
"org.apache.struts.action.RequestProcessor" at level "debug" although you might 
find a bit too much junk is being logged. 
(http://logging.apache.org/log4j/docs/api/org/apache/log4j/jdbc/JDBCAppender.html)

RE: session maintenance in struts webapp

[Lance Semmens]

You could either do it client side in javascript
setTimeout("confirmSessionExpire()", timeoutPeriod);

Or you could have a serverside thread and use DWR's amazing reverse ajax to 
push alerts to the client(s) that are about to expire. Reverse ajax is part of 
DWR2.0 and is not yet production stable but it's pretty close.

Subject: session maintenance in struts webapp

Hi Folks,
In my Struts 1.2.x based webapp, I intend to maintain a session for
every logged in user.
-- More details --
Say after 'n' seconds of inactivity I want to pop up a message
saying the session will expire in another 'm' seconds. The user can
click on 'refresh' button to get some more grace time else the session
will expire and the next time user tries to do something on the page, he
gets redirected to the 'login' page with a message - 'your last session
has expired, please login again'

I have already implemented SSL using SSLext tag-library (release 0 for
Struts 1.2.x) in my webApp. Can it help me in this case,

What other alternatives can I consider in this case,
Any tips/ideas will be much appreciated,
Regards,
robin

RE: RE: RE: [HELP] struts 1.2.9 multibox/checkbox in session scoped form

[Lance Semmens]

RequestProcessor is doing it's job by resetting the form. What should then 
happen is that your checkboxes should be set after reset() is called which 
doesn't seem to be happening.

Somethings not right here, esp since when you comment out reset, it works. Can 
you post your code? pls. include the relevant parts of struts-config.xml, your 
action and your form.

The only thing I can think is maybe you're explicitly calling reset()
in your action (instead of letting struts do it automatically). If
not, I suggest putting a debug breakpoint on the setters for your
checkboxes and see what's going on.

It's worked for me using a LazyDynaBean as the formbean and

RE: Dynamically adding row!

[Lance Semmens]

I realize your field names have to comply with the struts naming (ie so that 
BeanUtils.setProperty() will work. But if your form has a collection that you 
are adding a record to, struts will not create a new record, add it to your 
form's collection then set the properties on it. 

Once you do the create and add, struts will then do the populate. That's why I 
suggested the ajax call to add the record to the server side struts form so 
that the subsequent post will populate the fields.

You can have a form auto-populate from the javascript-generated
fields, you just need to be careful what you call the generated field
names. It will be hard-coded and none too attractive, but it will
work. Look at the rendered HTML to see what format the field names are
as an example.

RE: Dynamically adding row!

[Lance Semmens]

I realize your field names have to comply with the struts naming (ie so that 
BeanUtils.setProperty() will work. But if your form has a collection that you 
are adding a record to, struts will not create a new record, add it to your 
form's collection then set the properties on it. 

Once you do the create and add, struts will then do the populate. That's why I 
suggested the ajax call to add the record to the server side struts form so 
that the subsequent post will populate the fields.

You can have a form auto-populate from the javascript-generated
fields, you just need to be careful what you call the generated field
names. It will be hard-coded and none too attractive, but it will
work. Look at the rendered HTML to see what format the field names are
as an example.

RE: Validation + multiple Submit buttons

[Lance Semmens]

A JS free application? You can assume today's browsers have javascript, the web 
would break otherwise. Sure there are some cross platform issues but to go JS 
free is a tall order and will limit you to a clunky UI.

If JS free is your direction, you could wrap your back button in a  
that posts to a different action to your save.

Subject: Validation + multiple Submit buttons

Hi,

I have just begun to add validation to my forms using struts validator, which 
is quite nice. I have however a problem when I have more than one submit button 
on a form.

For example I have a Save button and a Back button.
The Back button is also a submit (instead of a standard button - basically 
because we are creating a JS free applciation!)

Within the struts configuration the validate is set to true for this action 
with an input page defined.
The validation is set to check certain fields are not empty.

As both buttons call the same action the validation is called on both, but I do 
not want validation to occur on certain submit actions (namely the Back button)

Ideally I would like to configure this in the XML Struts-config.xml or 
validation.xml but I am not sure if this is actually possible (I fear the worst)

If anyone has any tips, much appreciated.

Andrew

RE: setInput method of ActionMapping

[Lance Semmens]

A possible solution might be to 
1. Set validate="false" for your action.
2. Configure forwards for each of your error pages
2. Explicitly call form.validate() in your action 
3. Call saveErrors() if validation fails
4. Redirect to the appropriate forward

RE: RE: [HELP] struts 1.2.9 multibox/checkbox in session scoped form

[Lance Semmens]

The only thing I can think is maybe you're explicitly calling reset() in your 
action (instead of letting struts do it automatically). If not, I suggest 
putting a debug breakpoint on the setters for your checkboxes and see what's 
going on.

If I comment out my reset method then it populates the checkboxes
based on the form values like I want however I then loose the ability
to only get the checked value put into my action form after the page

A couple of things to check
1. Is your get action using the same form as your post action?
2. Do the names of the checkboxes in the html match your form?
3. Where are you resetting the checkboxes? I'm hoping you're doing it
by overriding ActionForm.reset().

RE: Dynamically adding row!

[Lance Semmens]

The least messy way is to post to an addRecord action which adds a blank record 
to your form. Form must be in session scope. This requires a page redraw so is 
less responsive but this is the approach I often use.

If you add a row to your table using javascript, struts will not automatically 
populate your form with the new record(s) upon save so you will need to handle 
this in your action. Unless of course you use ajax (which you have said you 
don't want to do) to add the record to your struts form on the server. 

Display tags will work for both suggestions. The javascript option usually 
involves cloning an existing row and blanking out the fields.

Officially... http://struts.apache.org/1.x/struts-taglib/tlddoc/html/select.html

"This tag is only valid when nested inside a form tag body."

What happens if you leave off  and use the 'name' attribute
of the select tag?  If the form bean (or some other bean) is in scope,
it might work.  I'd also review the code for the select tag and see
what else it expects to get from the enclosing form tag.

'name' - The attribute name of the bean whose properties are consulted
to determine which option should be pre-selected when rendering this
input field. If not specified, the bean associated with the enclosing
 tag is utilized.

Hot deployable actions

[Lance]

Hi, I've written a utility that uses a proxy to re-load a class if the
.class file has a later modified date than the last loaded date. I'd like to
plug this into struts so that my action classes can be hot-deployed.

I'm wanting some guidance about what classes I should interface / extend and
where this should be plugged into struts. Also any problems I may come
across. I realize that only 1 instance of each action is loaded per
application. This is fine, my proxy will be loaded once and the delegate
action (which of course has no member variables) will be re-loaded.

Cheers,
Lance.
