Subject: checkbox and iterate problem

Hi,
 I'm having a problem with checkboxes and I was hoping someone could help.

 The short version is:
   when using logic:iteratate over an array of checkboxes, the setter
method is not called after submit

 Long version
   I have class   CheckableString { String str; boolean checked = false;
// etc.. };
   I have a Form
   HostForm extends ActionForm {
 CheckableString[] mFolders = new CheckableString[100];
public CheckableString getFolder(int n) {
System.err.println(HostForm getFolder a  + mFolders[n]);
return mFolders[n];
}
public CheckableString[] getFolder() {
System.err.println(HostForm getFolder b  + this);
for (int i = 0; i != mFolders.length; i++) {
System.err.println(HostForm getFolder b  +
mFolders[i]);
}
return mFolders;
}
public void setFolder(int n, CheckableString folders) {
System.err.println(HostForm setFolder a  + folders +   +
this);
mFolders[n] = folders;
}
public void setFolder(CheckableString[] folders) {
System.err.println(HostForm setFolder b  + this);
mFolders = folders;
}
public void reset(ActionMapping a, HttpServletRequest b) {
System.err.println(HostForm reset  + this);
flag = false;
for (int i = 0; i != mFolders.length; i++) {
System.err.println(HostForm reset 
+ mFolders[i]);
if (mFolders[i] != null)

mFolders[i].setChecked(false);
}
}
}

I have an Action class setup the form, populating values from a
database,
it then forwards to a jsp page
html:form
..
logic:iterate id=quack name=hostForm property=folder
indexId=index
logic:present name='quack'
  tr
th align=left
   html:checkbox indexed='true' value='true' property=checked
name='quack' /
   bean:write name=quack/   bean:write name=index/
/th
  /tr
/logic:present
/logic:iterate



The form is populated correctly, items marked as true are selected. And
looking at the logs the getter function is called
The problem is when I submit, the setter function is NEVER called, and the
Form is not populated.
note: If I have a simple non-indexed checkbox, then that works as expected
and the setter is called

I am using struts 1.1RC1

Anyone got any ideas ??, I'm stumped

Thanks

Neal

After working on this for most of the day, I have discovered that Tomcat

for this (I have *got* to remember to check the bugs databases sooner
;-) ), but no analysis or corrective action has been recorded to date.
 
So, my question is this. What are people using for their DataSource?

Make sure commons-dbcp and pooling are not in your common/lib, use tomcat's.

Besides, I don't use struts datasource, I use Tomcat JNDI datasource and

At first, I tried to set an ActionError with this message and

It does not work because ActionError accepts as an input
string the key of a property.

So what's the nicest way to show to the user the error message

Subject: RE: Reporting an Exception message in a JSP.

Quick questiondo you really want the user to see a SQLException message?

Assuming that is really what you want, there are constructors for AE that
take a key and up to four objects that will be substituted in the error
value that is specified for the key.  The key and value appear in
ApplicationResources.properties.  So you could do the following in your
action:
catch (SQLException e)
{
ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError(sql.exception,
e.getMessage()));
saveErrors(request, errors);
return mapping.findForward(systemexception);
}


and then have this entry:
sql.exception=A database access error occurred.  {0}

The error message should then have the exception's message appear in it in
your error page.

Hope this helps

Solution 1:

- Add error to ActionMessage.
- Display the above message as a hidden field on the same page.
- Meanwhile, display a friendly message to user on the same page.

Solution 2:

- log exception to a file.
- display friendly message to user on the same page.

True but in my case I find it sometimes easier to turn on debugging 
from my browser on a live app to see what's causing the exception the 
user is seeing without having to look at logs or anything, so while the 
user never sees this error in normal processing, I can see the 
exception when trying to debug and figure out what's going on on a live

I don't know if this was the original poster's intent though.

I have to believe your issue is with nested tables and not Struts. Are you
experiencing performance problems with only pages containing nested tables?
The issue with nested tables has been fixed in Netscape 7. Try this browser
to see if the performance issues go away.

 Subject: Netscape 4.7x and Struts performance problems

 Several months ago there was a discussion in this list about poor
 performance of Struts applications when using Netscape 4.7x as a
 browser.  I've been developing in Netscape for quite a few years now and
 I don't think I've ever seen a more obvious difference between the
 performance of IE and Netscape.  I have other applications that are not
 based on Struts that perform much better, so the obvious thing is that
 this problem has to be related to Struts somehow, although its not clear
 how.


This could also be an artifact of the servlet container you are running.
For example, the peformance difference from running JSP pages with lots of
custom tags (i.e. your typical Struts-based app) on current Tomcat 4.1.x
releases, versus older ones, is nothing short of amazing due to
improvements in the JSP page compiler.

But these issues would cause visible performance differences for all
browsers, not just Netscape 4.7.x.

 Has anyone determined what causes this problem and how to resolve it?
 I'm aware that Netscape has a difficult time rendering nested tables,
 which we have minimized, however, other than use of Struts taglibs,
 there are no differences between the pages I am using now and the ones I
 have that do not use Struts, except that the non-struts ones perform
 much better in Netscape.


You're probably not going to like my advice, but IMHO Netscape 4.x should
be banished from the list of browsers supported by modern webapps.
Besides the performance related issues you allude to (which a server side
framework can't really do anything about), 4.x support for CSS and
JavaScript is pretty hideous.

 Any advice would be greatly appreciated.

 Thanks,

 Scott Carter

 I have to disagree with Craig on the issue of banishing ns4. We are all
 working on a *nix box. There are not many choices besides mozilla or ns.


Mozilla 1.2.1 kicks butt on Linux for me, including better performance
than Netscape on basically every website and webapp I access with it.  In
addition to the incremental rendering of nested tables (which improves
*perceived* performance even if it didn't change the total amount of time
requird), it's just faster at rendering everything than 4.7 was.

If you need to stick with the brand name to satisfy pointy-haired bosses,
Netscape 7 is based on the same rendering engine (Gecko) as Mozilla, so it
shares the improved performance and standards conformance (although it's
based on Mozilla 1.0 code rather than 1.1).

I faced a similar error in porting my application from Struts 1.0.2 to
1.1b3.   Problem persists on nightly (as late as Jan 31) as well.  I have
even written to Arron to see if he is aware of a problem.

You *may* be able to work around this problem by including the
nested_1_0.jar -- the jar that is to be used with Struts 1.0.  Since 'n'
comes before 's' alphabetically, this jar file is loaded before struts.jar.


While this may get you past the current problem you may trip up on others.
In my case, including nested_1_0.jar fixed the first problem but this
solution failed on a subsequent page -- I think  on a nested:define.

So, what am *I* doing?  I am back at Struts 1.0.2 since I don't have the
time to rewrite my entire application in a manner that works with 1.1.  Time
permitting, I might try to trace the cause of the error in the nested tags.

I am not expert. I use Tomcat and struts. I found that even though my app

Subject: RE: how to access a specific object inside a List efficiently

The problem you're hitting is that there's really no concept of a key in a
List - it's just an ordered collection of objects.  The closest you'd find
is the contains( Object o) method, but that looks for the entire object and
not just a key.  I would suggest using a HashMap for what you're looking
for.

As for the break on logic:iterate, I think the closest way to approximate
this is by setting up a flag for the loop such that you can do this:

set up loop flag
logic:iterate
  logic:equals name=loopFlag value=true
(do important stuff)
  /logic:equals
   set loopFlag to false when criteria are met
/logic:iterate

This won't save the loop iterations, but will keep extra content from being
written after you meet the criteria.  If possible, however, you may want to
trim your data set in the Action before you ever get to the jsp.

Subject: how to acccess a specific object inside a List efficiently


I have trouble to access a specific object inside a List based on a key. 
Before the first page, I load all the objects(meetings) into a list and only

show the name of the meeting to the user. By following the link (with id as 
parameter), user goes to the next page. Based on the id, I want to show the 
detail of the object (meeting). For my current implementation, I have to 
iterate through every single object in the list and try to match the key. It

works, but pretty stupid. Is there a better way to do it? Or should I use 
Hashmap (keyed by id) at the very beginning instead?

Also, to use logic:iterate, is there something like a break?

Thanks!
ds

First page:
  logic:iterate id=m name=meetings
  li
html:link
  forward=showMeeting
  paramId=id
  paramProperty=id
  paramName=m
  bean:write name=m property=name/nbsp;
/html:link
 /li
  /logic:iterate
It will build:
http://myproject/showMeeting?id=1

Second Page:
logic:iterate id=row name=meetings
logic:equal name=row property=id value=%=request.getParameter

  tr

 have a question: I'd
 like to know what's the best IDE/tool to help

 with Struts. I've seen some tools in the Struts
 resources page but I'm not
 impressed with them. In truth, I thought in a tool
 helping us to 'draw'
 pages with areas (tiles), buttons, input boxes, etc,
 in a way that we can
 access its properties and configure its name,
 validation rules, default
 values and so on. After creating our 'views', we
 could make the sequence of
 pages, like forward and redirect pages; and all
 visually. After all, the
 tool could generate my JSPs and the
 struts-config.xml file correctly. From
 the input boxes we could know what input fields the
 view need and generate
 the expected DynaBeans, with the respectives
 validations rules (previously
 setted). Following this idea, I thing we can
 generate our Views, FormBeans
 (DynaBeans) and Validations, and the ActionBean's
 skeleton; the user will
 just need to program the
 business rules (ActionForm.execute()).
 
 I've recently searched for drawing tools to create
 such 'framework' (or ide)
 and I find that MS Visio and System Architect has
 features that could
 produce this results. In truth, I want something
 like AllienFactory

(http://www.alien-factory.co.uk/struts/struts-index.html),

 more things visually.

RE: using tokens in struts,

[pqin]

In your DispatchTestAction class, after you populate the form bean
(request.setAttribute), call saveToken(request) ;

In your DoAction class, before you submit to database, check token
isTokenValid(request); if valid, continue process and resetToken(request);
otherwise, return a global forward which will forward your request to an
error page.

One thing you might change in your DoAction class is not to reload jsp,
instead, forward to DispatchTestAction class so that DispatchTestAction
class saves a new token for next submission.

I usually use a BaseAction class to save token, check token and reset token.
What my execute method looks like:

if (!validateLogin(request))
return mapping.findForward(getForwardError());
if (!validateTxnToken(mapping, request)) = check token
return mapping.findForward(getForwardError());
if (!validateActionForm(form, request))
return new ActionForward(mapping.getInput());

try
{
ActionForward forward =
performPostValidationAction(mapping, form, request,
response);
handleTxnToken(mapping, request); = save or reset token
return forward;
}
catch (Exception ex)
{
validateInternal(true, err.unexpected, request);

  I've seen a number of postings regarding a ServletException 
  that is thrown
  when a struts tag can't create a DynaValidatorForm:
  
  javax.servlet.ServletException: Exception creating bean of class
  org.apache.struts.validator.DynaValidatorForm: {1}
  
  Basically, when we restart tomcat (4.0.4 on unix, struts 
  1.1-b2) we are
  likely to see this error the first time we try to access our 
  webapp.  But
  then a second (sometimes third) restart of tomcat will clear 
  the problem and
  the webapps will function properly.  
  
  Is there any reason for this?  Does it have to do with the 
  location of the
  struts jar file?  Does it need to be in the WEB-INF/lib or 
  the common/lib or
  other part of the path?
  
  Has anyone been able to overcome this annoyance?

RE: problem of mapping

[pqin]

Those two parameters are totally different definitions.

Parameter in url is servlet request's parameter. Parameter in mapping is a
property of ActionConfig class.

Subject: problem of mapping

I have a problem to get value from parameter of a mapping inside of an 
action: 

IN ACTION: 

String parameter = mapping.getParameter(); 
System.out.println(pam :  + parameter); 

IN STRUT-CONFIG: 

  action path=/alterarSenha parameter=show 
type=com.neus.componentes.usuario.gui.UsuarioAction 
  /action 

action path=/alterarSenha parameter=change 
type=com.neus.componentes.usuario.gui.UsuarioAction 
  /action 

So, the string parameter shoud be show or change in output action. It 
depends only of the url in a form page: 

-- form action=alterarSenha.do?show ... 
or 
-- form action=alterarSenha.do?change ... 

But, just out in output in action change. why?? 
It seems that the second paragraf in the struts-config rewrite the first 
paragraf. I'm still a beginner of struts! :/ 

thanks

RE: proper use of back button -- design patterns

I want to bring up another issue.

The default behavior of RequestProcessor is to save everything into a new
ActionForm then do the validation. If token is invalid, why should we bother
populating the ActionForm at all?

Subject: RE: proper use of back button -- design patterns

The tokens are used for the user clicking the back button and trying to 
submit the form again.  What you describe would have to occur if the user 
clicked the submit button twice.  So, use js to prevent the double clicking 
and tokens to be sure the form is not submitted twice.

The javascript would be there as the first line of defense because the 
action will only be called once, and the submission will go through 
(assuming they do not have jscript turned off of course).  If an error 
occurs in that submission, the appropriate error handling will occur.

Contrast this to the situation where I check the token and forward 
somewhere else.  I don't know what happened in the first action submission.

  It could have been successful, it could have caused errors, the user will

have no idea.  All they will know is that they double submitted.  They 
could have kicked off a long asynchronous process, but because they were 
forwarded to badToken, they decide to go kick it off again.  Do you see 
now my issue with the token checking?  It seems like it really doesn't buy 
you a whole lot because you can't cancel the fact that the first submission

cause an action to execute.

You override the reset method to set unchecked value.

1. You know how many elements in your array, so instantiates your array.
2. You know the unchecked value of each element, so do a loop and set
default value to each element.

Try to utilize the parameter in your action mapping.

For loading action, parameter = load; for submission action, parameter =
submit.

Base action class logic:

If parameter is load
saveToken(request)
If parameter is submit
isTokenValid(request)
submit
resetToken(request)

The set-property applies to the ActionMapping, not the Action.  You can
subclass ActionMapping and add a useToken property to it.  Then the
action entity will need the className attribute set to your
ActionMapping subclass.

 I can't tell for Oracle, but for MySQL and the Struts Connection Pool
 you have to set some kind of autoReconnect=true for your connection
 url setup. Otherwise your connection pool will contain only stale
 connections after a certain timeout. 
 MySQL kicked me out after 8 hours of inactivity. 
 Without autoreconnect you will just pick a dead connection 
 out of this
 pool, get an exception, most likely even close the broken 
 connection in
 your finally-block and put it back into the pool. Next time you grab
 another dead connection and so on and forth.
 
 By the way... Are the certain pro and cons for the struts connection
 pool vs. the tomcat datasource connection pool?
 As far as I know the tomcat connection pool works only via jndi setup
 whereas struts utilized the oldfashioned way. And moreover 
 you have to
 set it up in struts-config.xml which is a bit tricky for deployment.

MJ,

using Digester and org.apache.commons.beanutils package, its not
that difficult to do this.

In our most recent project, we leverage DynaBeans heavily for creating
view objects to avoid having to physically create them (RowSetDynaClass
was not around). We define them in an xml file and read them into
memory at run time. So when we need a view it looks something like this:

ViewFactory vf = ViewFactory.getInstance();
DynaBean view = vf.getView(myView);

Adding a new view is as simple as adding a few lines of XML. This approach
allows use to leverage DynaBeans and not necessarily be dependent on Struts.

 Subject: Struts-config.xml and DynaBeans


 Hi,

 This is my very first contribution.  I am new to Struts and fairly new to
 JSP (so go easy on me).  I am working on a project that is considering
 using Struts 1.1.  So far I am very impressed, anything that reduces the
 amount of Java code I need to write gets my vote.

 I have been looking at dynabeans and the struts version of
 DynaActionFormClass.  I noted that in the Struts configuration file the
 section for describing form-beans.  This is great but being a very lazy
 programmer, what about a section for describing any type of DynaBean and
 not just form-beans specifically.

 The temptation is to write any DynaBean that I use in my web
 application as
 a form-bean in the Struts-Config file even when I have no intention of
 making it an actual form-bean i.e. writing a validate method or
 using it
 via a form.

 Other than that fact that it make my Struts configuration file confusing,
 any reason why I should not be doing this?

 Thanks,

 Mark

That's it in a nutshell :-).  Having to write fewer classes is goodness.

 While you don't have to write your own class with DynaActionForm, aren't
you
 restricting yourself to using Struts taglibs (especially the bean
taglibs?).

You're certainly dependent on commons-beanutils.

 What if you want to use JSTL now or sometime in the future?

If you look closely at the public API for DynaActionForm, you'll see the
getMap() method.  This returns the name/value map for the properties of
the DynaBean, and makes it pretty easy to use JSTL with DynaActionForm
beans.  For example, the following are essentially equivalent:

  bean:write name=customer property=name/

  c:out value=${customer.map.name}/

if customer points at a DynaActionForm bean.

 With the IDE's
 that we all use today, creating an ActionForm class with getter/setter
 methods is a breeze. Hence, what do you truly gain by using
DynaActionForm?

Not everyone has (or likes) an IDE.

It only resets numeric. For example, there is an amount property of your
bean which is a Double. If you enter abc and submit, abc is reset to 0.0. To
avoid this, change Double to String so struts can keep the original value.

But by using an action path for input instead of a JSP, isn't the 
ActionForm reset, so you no longer have your form values to show in the 
JSP again? How do you redisplay the incorrect values the user typed into 
the JSP?

RE: Action without forward ?

My writer writes binaries to output stream.

Stmt is an Oracle BFILE, response is HttpServletResponse, length doesn't
matter.

InputStream in = null ;
BufferedInputStream bis = null ;
ServletOutputStream writer = null ;
 
try
{
stmt.openFile() ;
in = stmt.getBinaryStream() ;
bis = new BufferedInputStream(in) ;
int length ;
byte[] buf = new byte[512] ;
writer = response.getOutputStream() ;
response.setContentType(application/pdf) ;
while ((length=bis.read(buf))!= -1)
{
writer.write(buf) ;
}
}
finally
{
if (writer != null)
writer.close() ;
if (in != null)
in.close() ;
if (bis != null)
bis.close() ;
if (stmt != null)
stmt.closeFile() ;
}
}

In my Action class, I return null.

It works perfectly if Adobe Acrobat Reader is installed.

 I don't understand why you cannot directly use the PDF-generator servlet,
by
 adding a dedicated mapping in your web.xml.
It needs to go through the request processor, to check if the user is
logged in
or not. 

 perform() method in any action MAY return an ActionForward, but CAN return
 null if it has build the response for the client browser. This is commonly
 used for PDF or Excel generation, where they're is no need for a JSP.

It writes the binary value(pdf) into the response.getOutputStream,
with content-Type application/pdf und with content-length set.
But in the browser nothing can be seen, even though the pdf that gets
created correctly,
and the browser is loading the pdf-plugin.


Any ideas ?

  Hi, I am using Struts 1.02 and got the following Problem:
  I need to create a JSP where u can select to create a pdf or excel file.
 
  The problem is, I didn't programm the Action to create the file, a
  colleague did.
  So I need some way to call his Servlet. I tried to map directly to it,
  that did not work. So I wrote an Action that called a method to create
  this pdf / excel file,
  depending on the parameters given.
 
  The problem is, that after this method there is no forward anymore, as
  the control is given to the servlet
  to create the file, and thats it. But the
  public ActionForward perform(
  ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
  {
 
  needs some forward.
  For the moment I wrote return null but imho thats no prober solution.
 
  Maybe you got an idea.

You must be coming from a VB background, as a DataGrid and a MSFlexGrid are
both MS COM components.

The equivalent of a COM component in Java is an applet.  But I caution you
on using applets in a web/browser based application UNLESS you are writing
an application for intranet (read: internal company) use.  For internet use,
where the general public will be using your web site, many of your IE users
will have problems running an applet, and will most likely give up on using
your site, rather than trying to figure out whether they have the right
version of the JRE installed on their machine, along with IE, to run your
applet.

Note also that 4.1.18 can be used to develop Servlet 2.2/JSP 1.1 apps

Subject: Collection within Collection

I have a collection (of ArrayLists) within a collection of (ArrayLists).
That is:

public class HistoryItemImpl implements HistoryItem {

private String objectName;
private List deltaList; ...
}

public class DeltaItemImpl implements DeltaItem {

private String columnName;
private Object oldValue;
private Object newValue; ...
}

In my action class I call a method that returns a collection of
historyItems.  I set that in request scope:

 request.setAttribute(historyItems, historyList);

And then iterate though it on me page:

  logic:iterate id=historyItem name=historyItems
type=com.gosps.cbd.util.HistoryItem 

For each historyItem iteration, I want to iterate though the deltaItems:

logic:iterate id=deltaItem name=deltaItems
type=com.gosps.cbd.util.DeltaItem 

How can I do this?  How do I refer to the deltaItem collection within each
historyItem collection?

Thanks.

RE: Collection Population Post-Validation Best Practice

I usually use two Action classes.

- LoadAction class to check if user is returned from page. Then I can
decide whether I shall populate page using what he has entered before or
instantiate a new page.
- Action class to process form submission and chain to next
LoadAction.

Personally, I like to keep my ActionForms as dumb as possible (I actually
use DynaValidatorActionForms). I see them as simple data transport
mechanism. When ever I have to prepopulate the ActionForm for a prepare
type of Action I do it within a the Action class (not explicitely - I
delegate to a service layer to handle this).

For me, this keeps things separate, simple and cohesive.

 Greetings again,

 I appreciate the afformentioned approaches (Robert, Karim, Puneet). I find
 Roberts to be the most logical, simple and clean for myself. I use
 LookupDispatchAction so this would actually be easy to do. I was
 getting the
 loop for the very reason you mentioned :-D. It was a test app to
 see how to
 address the problem of populating collections post validation and I was
 calling the process Action.

 So the practice would be to separate the entry Action from the process
 Action. Use the entry action as your input for errors and it will have the
 logic to populate your collections prior to showing the page.

 It also seems to me that the ActionForm does not exclude us from making
 calls to our business logic from within the validate method. So if I have
 any standard prepopulation (post validation)... I can just call my logic
 classes and set the appropriate members of the ActionForm from within the
 validate prior to the ActionErrors returning to the input page.

 Something like (with validator):

 public MyActionForm extends ValidatorActionForm {

 ...

 public void setMyCollection(ArrayList myCollection) {

   this.myCollection = myCollection;

 }

 ...

 public ActionErrors validate(
   ActionMapping mapping,
   HttpServletRequest request)
 {

 // run my validator validation and capture error
 ActionErrors errors = super.validate(mapping,request);

 // run my own validation
 if (x != 5) {

   errors.add(myErrorMessage,
   new ActionError(my.custom.error));

 }

 if (errors.empty())
 {
return null;
 } else {
   ...
   // populate ActionForm collections here and return errors
   this.myCollection = MyLogicClass.getMyCollection();
 //retrieves Collection

   return errors;
 }


 }

 }

 So then here is the final question:
 Is it appropriate practice to have logic classes being called in the
 validate method to populate collections in the form? What's the official
 position?

 Thanks,

 Hi

 What we have done is introduce a ListManager class. This is a singleton
 object that is accessible from the form via its superclass (our custom
 superclass).

 What we have done in our form is have two fields for a
 collection, i.e. our
 dropdown list. The first field is used to populate the values of the list
 and the second is used to store the selected value.

 E.G.:
 public Collection getListOfPeople() {
   return ListManager.getInstance().getPeople();
 }

 public String getSelectedPerson() {
   return selectedPerson;
 }

 public void setSelectedPerson(String selectedPerson) {
   this.selectedPerson = selectedPerson;
 }

 Our JSP is coded so that the setup of the dropdown calls getListOfPeople()
 and the selected item populates setSelectedPerson(). The taglib
 allows this
 Struts 1.1 b2.

 This allows us to store the forms in the request and never have to worry
 about pre-populating them, this seems to work very well for us.

 I would appreciate feedback wrt this approach.

 Regards,
 Karim

Hi all,
 
I'm pretty new to Struts but I've been following it for a long time.  Now
that I'm starting to use it, I'm trying to figure out the best way to make
objects available to a jsp that aren't involved in the processing of the
previous action.  I know about HttpServletResponse.addAttribute(), but what
if the action has little or nothing to do with the subsequent jsp?  In my
pre-Struts days, I would create something like 2 actions--the first one
services the incoming request, forwards to the next one, and the second only
gathers whatever info is needed by the next jsp (that way I can decouple
processing of unrelated concerns.)  Should I continue to do something like
this?  Or maybe create custom tags that know how to retrieve objects that
aren't in the response?  I'd appreciate some ideas.
 
thanks

session scope ActionForm

I am a bit confused about session scope of ActionForm.
 
For example, in my ActionForm testForm
 
private String field1 ;
private String filed2 ;
 
I instantiate testForm in a PageOneLoadAction
 
TestForm testForm = new TestForm() ;
Request.getSession().setAttribute(testForm, testForm) ;
 
On page one, I only need to enter field 1
 
html:form 
...
html:text property=field1/
/html:form
 
Once I subimit, I assume that value of field 1 is saved into testForm.
 
Now I load page 2 which only requires user entering field 2.
 
html:form...
...
html:text property=field2/
/html:form
 
If I submit, value of field 2 is saved into testForm. Will value of field 1
be kept in testForm?

I understand this topic has been discussed before, so I apologize for

Using strtus 1.1-b3, I'm creating a form bean that contains a
collection(ArrayList) and use it to populate the jsp using the iterate
tag.  With or without indexed attribute in the form elements (i.e
html:text  Indexed=true), I got the jsp to populate the data.
My problem is mostly in the action class where the form gets submitted.

If I don't set indexed=true, then the jsp is populated correctly. But
when the submit button is clicked, the the collection is always set to
null.

If I set indexed=true, and if I put indexed getter and setter methods
along with regular getter and setter for the collection, I would get No
getter method for property error when jsp is created.

If I set indexed=true, and if I don't have indexed getter and setter,
then jsp is created fine with correct indexed form field name, etc but I
would get java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 error
on submit.

I've been struggling with this issue since yesterday, and I'm running
out of ideas now.

Any comments would be greatly appreciated.

Hi,
I am new to Struts.  I want to know whether is there a way (or is it
possible at all?) to put the `ApplicationResources.properties' file in
another directory other than in the `WEB-INF/classes' directory onwards?
That is, I do not want `ApplicationResources.properties' to be in
`WEB-INF/classes' or any of its sub-directories.

TIA

Hi everyone,
 
I try to use Struts 1.0.2's SaveToken function to avoid duplicated
submit.  However I try to use the following logic to make it work:
 
Action = JSP (show the submit form without the data) = (click submit) =
Action with populated form = JSP (show the same jsp page to show the data
result)
 
I get the message duplicated request.
 
I think neither (1) it can use the same Action class to show and process
the data, nor (2) it can use the same jsp page to show the form and display
the result.  I use a debugger to know that the value of the hidden variable
for storing the saved session Token value is the same as the session Token
stored in session after I click the submit button.  That 's why the
isValidToken is false.  It is the bug in my coding or this is the default
behaviour of Struts?
 
Thank you!
 
Jason

 Maybe describe your enviroment more. Because I have similar situation,
 but have no problem with my Tomcat 4.1.18, mod_jk 1.2.0, Apache 1.3.27
 setup (opensa.org Apache)
 
 I'm developing a Struts App which is using both http and https (mainly
 for login).
 I mainly use html:form - post, sometimes I use get parameters, but
 only to send to action.do?test=value at the moment.
 
 I have Apache on 80/443 and Tomcat on 8080/8443 with 8009 mod_jk.
 Everything works fine for me... No matter if I access Apache and it's
 SSL port or use Tomcat standalone (which I also configured to 
 use ssl on
 8443).

  We have finished a large project which was based on Struts. 
  Now our client wants to use SSL. 
  We set up SSL and now our app. doesnt work anymore. It seems 
  that form beans aren't being populated. 
  I think that maybe struts control servlet cant read GET

  Our architecture consists of Apache HTTP server, which talks 
  to Tomcat. SSL support is installed in Apache server.
  
  Do you have ideas how to solve this problem ?

In a JSP 1.2 (or later) container, you can now nest multiple TLDS in the
META-INF/tlds subdirectory of a JAR file, and they will be
automatically
recognized by the container.  That means you do not have to use any
taglib directive at all in the web.xml file, if you don't want to, as
long as you use the official URIs for these libraries (it's in the uri
element of the TLD itself.

The Struts documentation still describes the techniques using taglib,
because the minimum platform is JSP 1.1 and automatic TLD recognition
for
multiple tag libraries does not work there.

Forget META-INF (sorry Craig). I think I finally figured it out.

Let's go back to old release (1.1b2). In my web.xml, I define

taglib
taglib-urimytiles/taglib-uri
taglib-location/WEB-INF/struts-tiles.tld/taglib-location
/taglib

taglib-uri is just a reference that you will use in your jsp. Treat it as a
variable name.

%@ taglib uri='mytiles' prefix='tiles' %
tiles:insert ./

location is where your file is located, relative path, don't if absolute
path works.

For those using Struts with Tomcat,
Any advantage or difference in using a Struts data source based on the
Jakarta Commons DataBase Connection Pool BasicDataSource class,
vs. using the Tomcat data source using the Jakarta Commons DBCP and 
Pool (configuring factory as
org.apache.commons.dbcp.BasicDataSourceFactory), 
registering the DataSource with a naming service based on JNDI ?

I was planning on configuring a DataSource with JNDI in web.xml/server.xml 
for database access, but then noticed that struts-config.xml has a 
data-source entry. 

Any opinions ?

Subject: Iterate Index Evaluation


I need to iterate over a collection and be able to tell whether the current
index is odd or even.  Any ideas on how I can use the logic tag for this?

logic:match name=index value=odd or even?


Thanks.

RE: Updating collections of information

[pqin]

Greg,

I have to correct my posting.

In my OrderEntryForm, there is an instance variable called lineItems.

In my reset method,

I first instantiate it using lineItems = getOrder(request).getLineItems().
Then I set the checkbox and let struts to populate the line items. You don't
have to keep a copy in session, instead, you can

- keep the size in session.
- in reset method, instantiates a new lineItems(size in session).

I keep two copies (one in request is enough for init values) - because I am
dumb - because I am lazy - because I want to send that much information to
the database - because.. Two-copy will not work for a large multi-row
form (mine is only few rows).

All struts need is how to create a new instance of your collection, I give
it two much.

Regards,
 
 
PQ

If your solution is working for you, it cannot be too dumb, and you are
ahead of me.  I agree with your guesses for struts behavior.  I added a line
in reset() to pull the collection bean out of the session and into the form.
This alleviates the NullPointerExeptions, but I am still missing the magic
that happens in the step where Struts saves all the values into this
object.  The sample app prints out A B C even though I modified the values
to be D E F.  It may be time to concede defeat.

I appreciate your time and assistance.

My solution is pretty dumb because it keeps two copies of ActionForm.

1. In orderEntryLoad action (before I load order entry page)

I retrieve line items from database and save two copies of them. One in the
session (see point 2), the other in the request so I have all the initial
values of this ActionForm.

2. In orderEntry action (after I click Submit button)

My guess for struts's behavior is

- Struts instantiates an instance of ActionForm.
- Struts calls reset method to create a new lineItems object. I override it
so as to make it an exact copy of the lineItems I stored in session.
- Struts saves all the values into this object.

Now I can save this ActionForm to database.

Subject: RE: Updating collections of information

PQ, please bear with me because I think you are doing what I would like to
do.  I sincerely appreciate the hand-holding as this is my first Struts
project.

In your example, the page displays line items and it appears the user could
potentially update stringOrderAmount and mark items for removal.  When the
form is submitted, does your action class simply call getLineItems() and it
returns a collection of line items with the updated stringOrderAmount(s) and
markedForRemoval flags?  I assume so, and this would be analogous to what I
am attempting to do.  I simply have one extra CollectionBean layer because
in reality, this bean has other attributes besides the collection.

Can you elaborate on what getOrder(...) does?  It returns an iterator, so
obviously it has access to a collection, but what collection (lineItems
variable in your form class?) and how did it get populated?  This is the
heart of what I am missing because my form always returns null on the call
to getCollectionBean().  After adding a line, this.collectionBean = new
CollectionBean(), to the CollectionForm constructor, then
getCollectionBean() returns an object, but calling getElements() on the
object returns null.  Does your form have session scope or request scope?
Is my problem related to putting the collection bean directly into the
session?  If so, how do I wrap it inside the form (the
PopulateCollectionAction doesn't know what Form is expected by the
subsequent UpdateCollectionAction)?

Also, you use a prefix of 'nested'.  To what tag library does this refer,
and is it important to the solution?

Sample Code I am using to test:
-

public class PopulateCollectionAction extends Action {
public ActionForward perform(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse) throws IOException, ServletException {
Collection c = new ArrayList();
c.add(new ElementBean(A));
c.add(new ElementBean(B));
c.add(new ElementBean(C));
CollectionBean bean = new CollectionBean();
bean.setElements(c);

Odd and even is not the only way of doing that, you can also switch between

I found the RowTag by Amarda Business Systems Ltd useful for doing different
colors based on odd or even rows...

looking at their source they use logic like:
boolean evenNumber = (getRowNumber() % 2) == 0 ? true : false;

to determine odd or even where getRowNumber() essentialy gets the iterators
index.  Pretty much the same logic as what you came up with.

Thanks, but I think there will be a problem with the bean:define since the
jsp 1.1 spec does not allow you to use the same bean name more than once in
a single page (which is what we would be doing in an iterate tag.)  Unless
I'm misinterpreting.

ArrayDescriptor - GenericConnection exception

* From: Eva Garabedian
* Subject: ArrayDescriptor - GenericConnection exception
* Date: Wed, 12 Jun 2002 16:24:31 -0700

Hello List - I've got a question about passing a string array into an
Oracle Procedure. 
Specifically, my ArrayDescriptor assignment line is throwing a struts
exception, whose message is simply
org.apache.struts.util.GenericConnection.
I'm using a CallableStatement in my Java code to pass my String[] to my
Oracle procedure. Before I added the String[] parameter, everything was
working quite nicely. Now when I run this I get the dreaded
NullPointerException in the Tomcat messages in my browser, and the first
System.out.println (found below) shows up, but the GenericConnection
exception is thrown before the second println executes. This leads me to
believe that the ArrayDescriptor is the culprit. In the following code,
please note that the user_type NL_GROUP exists in my database, created
by the user CREATOR.

Thanks in advance for any suggestions about where I should look for
help. 



Here is my related code: 
public boolean addCustomer(String userName, String password,
String[] nlGroup) throws Exception  {
 
   Connection conn = null;
   CallableStatement stmt = null;
   String sql = {call INS_CUSTOMER_AND_CONTACT_INFO(?, ?, ?)};
 
   try {
 conn = dataSource.getConnection();
 
 System.out.println(After getConnection. );
 
 ArrayDescriptor desc =
ArrayDescriptor.createDescriptor(CREATOR.NL_GROUP, conn);
 
 System.out.println(After arrayDescriptor assignment. );
 
 ARRAY newArray = new ARRAY(desc, conn, nlGroup);
 stmt = conn.prepareCall(sql);
 stmt.setString(1, userName);
 stmt.setString(2, password);
 ((OraclePreparedStatement)stmt).setArray(3, newArray);
.
.
.

Hi
 Sven's suggestion on returning null in ReportAction got me past the
problem 
of not being able to run the report generation a second time
consecutively. 
Now, another problem still remains. In ReportAction depending on various 
conditions I am doing processing and forwarding back to the calling page or
if 
it is specifically a report generation I am returning a null(as per sven's 
suggestion). But what is happening here is if I keep doing a submit from the

JSP only for report generation consecutively  the report generation works. 
Now, when I do a submit for another operation from the same JSP  
ReportAction does the processing and forwards back to the JSP successfully, 
but then if I hit the report button i.e to generate a report... 
ReportAction breaks down with this exception (after the stack trace I have

typed in some of my thoughts so please read them)..

Subject: Updating collections of information

I've read the Struts User Guide, Programming Jakarta Struts, searched
Google, and asked a couple of acquaintances, but have yet to find a
definitive answer to whether Struts can help me in the following situation.
The closest thing I've found is a reference to IndexTags under Struts
Resource.

I have a form which correctly displays information found in a collection of
beans.  However, each piece of displayed information is potentially
updateable.  When the form is subsequently submitted, does Struts
rebuild/update the collection of elements?  I suspect it doesn't because
attempting to retrieve the collection from the form bean returns null.  If
not, any suggestions as to how I should handle this?  Shall I resort to
using straight html elements with a naming convention and Java scriptlets,
as opposed to trying to use the struts html element tags?

Sample portion of JSP:
logic:iterate name=selectedBean id=element property=elements
type=xxx.yyy.ElementBean indexId=rowNum 
  tr class=%= rowNum.intValue() % 2 == 0 ? evenRow : oddrow % 
td align=lefthtml:text name=element property=propertyA//td
td align=centerhtml:checkbox name=element
property=propertyB/html:checkbox/td
td align=centerhtml:checkbox name=element
property=propertyC/html:checkbox/td
  /tr
/logic:iterate

I am using Struts 1.0.2 and Tomcat 4.1.12.

Any assistance, or confirmation that this is not possible with Struts will
be appreciated.  Thanks.

You can do this with the Struts-EL library, which is part of the Struts
distribution.  Using this, your tag could look like this:

  html-el:link forward='${menuOpt[forward]}'
target='${menuOpt[target]}'/

The Struts-EL library uses the JSTL expression language engine for
evaluating attribute values.  Struts-EL requires a Servlet 2.3-compliant
container.

RE: Updating collections of information

[pqin]

My solution is pretty dumb because it keeps two copies of ActionForm.

1. In orderEntryLoad action (before I load order entry page)

I retrieve line items from database and save two copies of them. One in the
session (see point 2), the other in the request so I have all the initial
values of this ActionForm.

2. In orderEntry action (after I click Submit button)

My guess for struts's behavior is

- Struts instantiates an instance of ActionForm.
- Struts calls reset method to create a new lineItems object. I override it
so as to make it an exact copy of the lineItems I stored in session.
- Struts saves all the values into this object.

Now I can save this ActionForm to database.

Subject: RE: Updating collections of information

PQ, please bear with me because I think you are doing what I would like to
do.  I sincerely appreciate the hand-holding as this is my first Struts
project.

In your example, the page displays line items and it appears the user could
potentially update stringOrderAmount and mark items for removal.  When the
form is submitted, does your action class simply call getLineItems() and it
returns a collection of line items with the updated stringOrderAmount(s) and
markedForRemoval flags?  I assume so, and this would be analogous to what I
am attempting to do.  I simply have one extra CollectionBean layer because
in reality, this bean has other attributes besides the collection.

Can you elaborate on what getOrder(...) does?  It returns an iterator, so
obviously it has access to a collection, but what collection (lineItems
variable in your form class?) and how did it get populated?  This is the
heart of what I am missing because my form always returns null on the call
to getCollectionBean().  After adding a line, this.collectionBean = new
CollectionBean(), to the CollectionForm constructor, then
getCollectionBean() returns an object, but calling getElements() on the
object returns null.  Does your form have session scope or request scope?
Is my problem related to putting the collection bean directly into the
session?  If so, how do I wrap it inside the form (the
PopulateCollectionAction doesn't know what Form is expected by the
subsequent UpdateCollectionAction)?

Also, you use a prefix of 'nested'.  To what tag library does this refer,
and is it important to the solution?

Sample Code I am using to test:
-

public class PopulateCollectionAction extends Action {
public ActionForward perform(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse) throws IOException, ServletException {
Collection c = new ArrayList();
c.add(new ElementBean(A));
c.add(new ElementBean(B));
c.add(new ElementBean(C));
CollectionBean bean = new CollectionBean();
bean.setElements(c);

httpServletRequest.getSession().setAttribute(theCollectionBean, bean);
return(actionMapping.findForward(displayCollection));
//displayCollection.jsp
}
}

-

public class UpdateCollectionAction extends Action {
public ActionForward perform(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse) throws IOException, ServletException {
CollectionForm f = (CollectionForm) actionForm;
Collection c = f.getCollectionBean().getElements();
//NullPointerException
for (Iterator i = c.iterator(); i.hasNext();)
//NullPointerException
{
ElementBean e = (ElementBean) i.next();
System.out.println(e.getValue());  //This should
print D E F.
}
return(actionMapping.findForward(start));  //index.jsp
}

-

public class CollectionForm extends ActionForm {
CollectionBean collectionBean;

public CollectionForm() {
this.collectionBean = new CollectionBean();
}

public CollectionBean getCollectionBean() {
return collectionBean;
}

public void setCollectionBean(CollectionBean collectionBean) {
this.collectionBean = collectionBean;
}
}

  That should fix things, I believe.  The commons-logging package

  It's not going to work correctly until you configure it

Thanks for the reply.  I tracked down what was happening.

The error was a NoClassDefFoundError on org/apache/log4j/Layout,
despite the fact that I have log4j-1.2.7.jar and log4j.properties
in the WEB-INF/lib directory.  So it looks like the server is
looking for Log4J as the web app is actually being loaded and
prior to the web app's jars being put in its classpath.

I put the jar and the properties file into the lib directory for
the server, in this case JRun puts them in jrun/servers/xxx/lib
(for a server named xxx).  Now it loads the web app properly
without the error.

I don't like this, because it means my web app can't be self-
contained and distributed just as the war.  I'd have to look at
the specs to see if JRun is behaving correctly by not putting the
web app's jars in the classpath prior to initializing the web app,
but even if it is behaving incorrectly, that's the way it works,
so I guess I have to deal with it.

I hope maybe this helps someone else...

I'm integrating some struts functionality with a pre-existing, html based

to index.jsp.  However, i've tried action=logon,
action=/summershow/logon and it says The requested resource (/logon) is

know an html form just won't work.


First, any thoughts why the following html form tag won't work, and second,
what is the standard solution for this situation, .jsp or .html?


form action=/summershow/logon method=post name=logon
input name=username type=text
input name=password type=password
input name=submit type=submit
/form

responds with

The servlet is under catalina/webapps/summershow/WEB-INF/ . . .  The working
code looks like this.

difference and which one should I use in this case?

Thanks,
Suresh

Do you know of any good reading that elaborates on writing a global
exception handlers for Struts?

I've already read
http://jakarta.apache.org/struts/userGuide/building_controller.html#exceptio
n_handler ,

but am looking for more detail or a tutorial.

Thanks,

--Mike

RE: Problem Using Log4J and Commons Logging with Struts

Sorry, I am talking about Tomcat. Maybe it is bug for JRun.

Just because two libraries use each other's classes doesn't mean
their classes (or jars) need to be in the same directory.  They
just need to locate each other's classes in the classpath.

A web container places WEB-INF/classes and all the jars found in
WEB-INF/lib into the classpath for the web application.  I don't
know for sure (I haven't researched the specs), but apparently
these are supposed to be placed in the classpath prior to
initializing the web application.

JRun apparently has a bug where it does not put these in the
classpath early enough, so when some components of Struts (or
something else that depends on Log4J) initialize, they can't
find the Log4J jar file, and hence the NoClassDefFoundError.

It probably works for you to just put the Log4J jar into
WEB-INF/lib under a different container, and I'd really like it
to work this way for JRun as well, but it doesn't, so I need to
put the Log4J jar and properties file into the shared server lib
directory (jrun/servers/lib) for it to work.

That is why it is in a different directory.

Paul

disable enter key

[pqin]

Dumb question. Is it able to disable Enter key without using JavaScript on
any struts-powered page?
