Re: Apparent bean:struts / DynaActionForm Class Incompatibility

[darryl . staflund]

Thank you very much Kris :-)  I've never worked with the FormBeanConfig class before, 
so I thought you were using a generic name in your last letter for the sake of 
example.  I'll brush up on the class and make sure I familiarize myself with more of 
the Struts API before posting in the future.  I appreciate your help.

Re: Apparent bean:struts / DynaActionForm Class Incompatibility

[darryl . staflund]

Hi Kris,

Thanks for your help.  I think I described my problem a bit incorrectly.  This is how 
I get an error:

1.  At the top of the JSP page, I have the following:



2.  Later, I try writing the value of one of the properties as follows:



3.  This results in the following error:

org.apache.jasper.JasperException: No getter method for property description of bean 
theDocumentForm

If there is no casting issue going on, then I am not sure what I am doing wrong that 
would lead to this error.  Any suggestions?

Apparent bean:struts / DynaActionForm Class Incompatibility

[darryl . staflund]

Hi all,
Does anyone know how to get around the following problem:

1. I am using a DynaActionForm class to mediate data exchange between my JSPs and and 
Action classes.

2. In one JSP, I use the  tag to copy one DynaActionForm class to a 
page scoped scripting variable.

3. Once I have done this, though, I can no longer access the properties of the bean 
through the scripting variables because the 'getter' method for that property cannot 
be found.

Here is what I think is happening. The  implicitly assumes that my 
DynaActionForm class is actually an ActionForm class. Although this is true since 
DynaActionForm subclasses ActionForm, their getter and setter methods are quite 
different. Getter methods in the ActionForm class take the form of 'get')'. 
Since my class is of the type DynaActionClass, my JSP fails.

Does anyone know a workaround to this?

Darryl

RE: [STRUTS] Please !

[Darryl Nortje]

Kiuma, without sounded condescending or anything, just by looking at the
error msg you got it seems to besomething wrong with your jsp page. I
haven't looked at your jsp page yet, but from a debugging, or problem
solving point of view, change your jsp page to simply say "testing" nested
in two  tags. Then start adding more and more tag to it, untill you
eventually have the jsp page shown below. You're getting a Nullpointer
exception in the userlist.jsp. So a variable that you're trying to access in
the jsp is null. Are you setting the variable in your action class???

RE: Dynamic name to the text fields

[Darryl Nortje]

Well, the way I did it was select from a table and in the while (rs.next())
loop build up the collection.

I don't know your particular scenario so can't help you there, other than to
say that you build up the collection as part of an action, or from a
database, depending on what you want to do at the end of the day

First, google around for "map-backed ActionForms" or similar. There's some
stuff over on jguru that might be helpful. Also, I'm trying to write
documentation for the struts user's guide for this, so I'd appreciate your
comments on how (un)clear the following is (apologies for the formatting,
my mail client sucks):


  The DynaActionForm classes offer the ability to create ActionForm
beans
 at initialization time, based on a list of properties enumerated in the
struts
configuration file. However, many HTML forms are generated dynamically at
request-time. Their ActionForm beans' properties are not all known ahead of
time, so we need a new approach.
  Struts allows you to make one (or more) of your ActionForm's
properties
' values a Map instead of a traditional atomic object. You can then store
your form's dynamic fields' data in that Map. Here is an example of a
map-backed ActionForm class:



  In its corresponding JSP page, you can access objects stored in
the values map using a special notation: mapname(keyname). The
parantheses in the bean property name serve to indicate that the bean
property named mapname should be a Map, and that struts should look
at the value stored with the key keyname in that Map to find the
"real" property for mapname(keyname).
  Here is a simple example:



  This will call the getValue() method on FooForm with a key value
of "foo" to find the property value. To create a form with dynamic field
names, you might do something like this:





Hope it helps, thanks in advance for any comments.

RE: How to retrieve value from actionservlet?

yes you can. Let's say your user object, is you form class. or similar
bean... it has in particular a getFullname() method. You store this user
bean on the request or session as "userstuff". Then when you want to write
out the username on a jsp page all you do is this -->   .

I don't see why this shouldn't work

Hi Daryl,

Thank you for your help. But, please bear with me
because I am trying very hard to make some sense out

object and then retrieve it later on my JSP page? In
other words, can I do the following?

I see what you're saying... I don't know why it doesn't work.

Using the equal tags, what is the best way to compare a value retieved from
a Hashmap?

I would like to put a Hashmap (or similar)  into request scope and use the
logic:equals tag. and do something like this.

 Show A 
 Show B 
 Show C 

Do I need to wrap this in simple class?
The docs make reference to the support of indexed properties, is there a
way to get the tag to look up the name of the key?

try this in your action class.

You have an instance of the form object.

UserInfoForm userForm = (UserInfoForm) form;
then...
String fullName = userForm.setFullName(fullName);
return mapping.findForward("success");

then on your userInfoConfirm jsp you say


That should work...

This is how I got it of my form object


and this is how I got it out of a collection object



In the form object I have a getJspAction() method and in the collection
object I have a getIsReadonly() method.

I think with Hashmap you just need key or value, so where you have
property="mapkey1" change to key or value

Subject: Hashmap and logic:equal


I am hoping that someone could point me in the right direction.
 I have been searching the archives and have not come accross anything that
I can relate to.

Using the equal tags, what is the best way to compare a value retieved from
a Hashmap?

I would like to put a Hashmap (or similar)  into request scope and use the
logic:equals tag. and do something like this.

 Show A 
 Show B 
 Show C 

Do I need to wrap this in simple class?
The docs make reference to the support of indexed properties, is there a
way to get the tag to look up the name of the key?


Thanks All

RE: please, help! debugging Struts with VisualAge for Java and Tomcat

[Darryl Nortje]

I am using VAJ4. It has Websphere Test Environment. I use that and then am
able to debug the webapp. I don't know if VAJ has a tomcat plugin, but
that's probably what the article Adrian sent you is all about.

If you want the full installation instructions for websphere test

Iterate tag within an iterate tag

[Darryl Nortje]

Went through the achives to find out if having an iterate tag within an
iterate tag is possible. Didn't find anything.

So basically, my question is 1) is it possible. and 2) if so, how.

This is what I've done, but it's not working..


I am then able to access all this collections getters if they are returning
String via the 

if the getter returns a collection, how do I iterate through that result

the getter in the bean is (in this case) getAttDetails() for the collection
that I now need to iterate through.

If I do this  in the
first iterate tag it prints out the following to my jsp
[com.ag.armata.contentserver.OptionBean@475d,
com.ag.armata.contentserver.OptionBean@6275], which looks to me like it's
just simply calling the toString() method on the object. What I, in essence
want to do is this>



" id="attDets">
 = 


 This obviously does not work...
Does anyone know how to do what I've tried to explain as best as possible
here.

Thanks

RE: HTML / Struts Help

[Thompson, Darryl]

Hello,

When my JSPs contain multiple buttons that trigger different behaviour I use
the DispatchAction...

Here is a snippet of html for defining a button:
 

   //...

 In my struts-config.xml I create a mapping like this:
   
  
  
  
  


Then in the DispatchSalesOrderSetup class I handle any pre-page processing
in an execute(...) method before 
forwarding control to the appropriate page. The great thing about the
DispatchAction class is you don't have to code any conditional logic since
it uses
reflection to map the request argument (in this case the  "method"
parameter) value to a method name in the DispatchAction subclass.

Hope this helps...

RE: Best Approach for Database Access?

[Thompson, Darryl]

Hello Keith,

 In my environment we employ options 2 and 3 but with this little twist:

  3) EJB environment (CMP)
 JSP -> ActionBean -> ( ServiceHelper -->ServiceLocator ) - >
ServiceBean -> DB

The ServiceLocator is a regular Java class that encapsulates all jndi Home
lookup logic, and the ther ServiceHelper is also a regular Java class that
contains methods to
support the business model. All ServiceHelper methods are static and the
Action Class calls these from the appropriate exec(..) method.

We are still trying to get a handle on this framework so if this is in left
field let me know.

Darryl

RE: Smart login page

[Darryl Nortje]

I'm very new to Struts and the MVC design so if I get this wrong please
everyone let me know. Or rather let Stefano know how to do it. I'll get the
reply.

Stefano, the answetr to your question is 'Yes'. very vague but this is how I
see it working. 

You have two pages A, and B. Flow goes from A to B. Inbetween going from A
to B you have a check to see if user is still logged on, if he is not logged
on your controller servlet show the user the logon page, after success at
logon, the controller servlet knows that it must now show page B. Does this
make sense? Your logon page can be called from multiple parts within your
app.

RE: problems getting struts example to run

[Darryl Nortje]

Hi Jon,

Ja, you were right Jon. I changed the wrong one. Now that it's working can
you tell me at all what was wrong with 
"pageContext.removeAttribute(Constants.BEAN_KEY,
PageContext.REQUEST_SCOPE);"
and why 
"pageContext.getRequest().removeAttribute(Constants.BEAN_KEY);" works.

Is something wrong witht he Struts code?

Hi Darryl,

There are to FormTag(s) in different packages. Make sure you have edited the
one in the org.apache.struts.taglib.html package. If Struts is in your VAJ
workspace put a break point in the class to ensure that the WTE is using
this copy when running and not another on your classpath.


Jon.

Hi Jon, I changed the two lines to what you said. I did not make any
difference still got the error
java.lang.IllegalArgumentException: cant remove Attributes from request
scope.

There is something wrong with the Constants.BEAN_KEY. it is either not being
set which I was trying to trace in the FormTag.doStartTag() at the last line
--> pageContext.setAttribute(Constants.BEAN_KEY, bean);

I can't see anything wrong with the way it is setting the attribute, so the
way it is removing the attribute should not be a problem. Any more ideas you
might have would be welcome. I'll keep going on? Thanks again for the
replies.

RE: When to store files in DB vs. File system

[Darryl Nortje]

Hi. 

Everyone is going to tell you that you must store it in the database. The
reason are that in different OS's, there is a limit to how many files you
can store in each directory. (windows i think is 1). I was faced with
this same problem under a time constraint, so never took the time to figure
out how to store the file directly into the database. So i went the a
directory storing route. What I did was Create a directory
root\1\1a\1aa\file.extension like this. Set a limit to the amount of files
in this directory and when that limit was reached incremented the directory
name to root\1\1a\1ab etc etc. And then just stored the directory and
filename in the database and retrieved it like that. I'm pretty sure that
this is not the correct way to do this sort of thing, but it does work. I
will be watching this mail to find out how to do it properly.

Hello, I am developing a webapp where users need to
store files (<200k).  I am wondering if these should
be stored in the (mysql) database, or in the file
system.  I am concerned about the number of files I
could get in the database (possibility for 20,000+
users, so 100,000 files).  On the other hand, I plan
on replicating my database across multiple servers. 
Do I then also replicate the download of each file, or
run a batch that copies them periodically?  I would
greatly appreciate advice from anyone who has dealt
with these design issues.  Thank you, Andrew Timm

Hi,

Have you added the ActionServlet mapping into your .webapp
file? This mapping tells the action servlet where to find struts-config.xml.
If you have the mapping what entry do you have for the config parameter?

I'm configuring the Struts Action servlet on WebSphere 3.5.2

I have the following file:

And the documen root of my web application is:

It is ok? Where shold be placed struts-config.xml? IMHO this

RE: Tiles/Orion(Oracle)

[Darryl Pentz]

Hi Cedric,

So is there (was there) a known bug with Orion then? This sounds very much
like the problem I had with Orion where a search form worked the first time,
and then subsequently only returned the page of the first search's results.
The JSP seemed to hang at the  start tag.

Could you please explain what the problem was? I only recently rejoined the
mailing list so I'm not privy to previous discussions. Also, will the latest
Struts nightly build have your fix in it?

thanks,
Darryl

RE: Duplication of Template Files Solution

[Darryl Pentz]

Sandeep,

Can you post an example of a struts-config mapping using Tiles. I tried to
use Tiles but couldn't get it to run a page twice. In other words, I had a
search function which worked fine the first time with Tiles, but when I
changed the search criteria and resubmitted, the Action class ran, but when
it forwarded the result to the JSP, the application hung at the insert tag.
This is what prompted me to try the inline thing with the original Struts
template tags and it worked, without any changes, so I deduced that Tiles is
buggy. I'm running Orion on Win2K with a nightly build from about 10 days
ago.

I didn't know about being able to reference the Tiles definition from the
struts-config action mapping, hence my request above.

thanks,
Darryl

RE: Problem with Struts and Weblogic 6.1 SP1

[Darryl Pentz]

I last worked with Weblogic at v5.2 so bear that in mind with my comments.

WL has 2 classpaths... one for itself, the application server, and one for
the applications it runs. My guess is that you DO need to include struts.jar
in the classpath for WL since the servlet is installed before WL looks at
the WAR file.

Duplication of Template Files Solution

[Darryl Pentz]

I've discovered quite by accident that the Struts templating framework
allows me to eliminate duplication of my JSP pages by simply including the
body page inline to the template definition page. By this I mean I combine
both pages into one as follows:






... BODY HTML GOES HERE ...




I'd previously enquired on this list how I could eliminate the duplication
of the pages where the main body HTML exists in a separate JSP page that is
simply referred to from the definition file i.e. . Strangely nobody responded with the above
solution so I'm wondering is this simply a side-effect of the PutTag class
or Craig, did you intend for it to work this way? I'm quite surprised I
haven't seen this technique used in any of the examples. Rather, the
duplication is suggested. The new Tiles extension allows the above which
prompted me to try it with the Struts template tag library just for grins,
and it worked!

Is there a problem with doing it inline like I illustrate above? I looked at
the source code and I see the PutTag class does extend BodyTagSupport so
everything should work fine. So far, the stuff I've played around with seems
to work fine with no problems.

Any feedback would be appreciated.

thanks,
Darryl Pentz

Tiles Problem

[Darryl Pentz]

Hi all,

I sent this email yesterday but it doesn't seem to have gotten through to 
the list, so I'm resending. Basically, I have a problem with Tiles execution 
of templates (components). I'm using the design where the main body of the 
page is inline to the  tag. In other words. I have:


   
   
   

   ... main body HTML here ...

   


This helps me eliminate the need for duplication of the pages. I thought it 
was working fine when I got the first page of my search page functionality 
to work. However when I re-run the search, the page simply redisplays the 
results of the first search, even though the Struts Action class correctly 
goes off and retrieves the results of the second search and places the 
result in the session.

I placed a simple <% System.out.println("Top of page reached."); %> above 
the insert tag and it is displayed on the console on the search retry, so it 
seems like somethings hanging trying to execute the template tags for the 
second time. One time, in frustration, I hit the 'Search' button numerous 
times, and when I Ctrl-C'ed the app server, a whole bunch of 'Connection 
reset by peer' stack traces appeared before the app server shut down, 
indicating that my requests were waiting somewhere. Where? I don't know.

So if someone has some idea where things might be going wrong, I'd 
appreciate any pointers. Cedric? Is there something in my code I should look 
for. It's not hanging at a point that it could be due to my code having a 
threadlock so I'm confused.

thanks in advance,
Darryl Pentz

Tiles Problem

[Darryl Pentz]

Hi All,

I'm having a problem using Tiles (nightly build of Struts). Cedric, I don't 
know if you'd perhaps be able to give me a suggestion.

I'm using a template and including the main body of the page inline, i.e. 
within the  tag. So I have a number of tags as 
follows:







... main body HTML here ..



In the backend Struts classes I trace the objects activity to see what's 
going on. When I do a search the first time, the page redisplays with a list 
of search results. However, if I do another search, the page simply 
redisplays the first search results, no matter what I input. However, 
looking at the trace, the system is performing the search successfully. It 
seems however that after the first search, and results display, when a 
second search is performed and the system does a findForward() back to the 
results page, the JSP execution goes awry at the first insert tag and just 
hangs... it doesn't return. I know this because I inserted a simple <% 
System.out.println("At start of page"); %> before the  
tag and this shows up on the console, but the results don't show on the 
browser... or at least, not the correct results, even though they are 
correctly retrieved. Sorry, I'm repeating myself just so I'm not ambiguous 
about anything I've explained about the problem.

One other clue is that when I got frustrated one time and hit the Search 
button a number of times, and then hit Ctrl-C to kill my appserver, the 
server suddenly spewed out a bunch of stack traces indicating connection 
reset by peer. So it seems like all my requests were queued somewhere 
waiting for a JSP resource or something to be released or something of that 
nature, but I'm not sure where.

Anyway, any help will be appreciated. I really like using the design above 
because it prevents me from having to duplicate all my template definitions 
and the main body pages and just combine them into one page.

regards,
Darryl Pentz

RE: File Upload Problem

[Darryl Pentz]

Just to confirm to the NG that we do seem to have a problem with the way
that org.apache.struts.upload.MultipartIterator.java does the
createLocalFile(). I've tested this quite a bit today and have found that
Struts-b1 worked fine with this spreadsheet. Thereafter, the
createLocalFile() was COMPLETELY redesigned and it's also with this redesign
that the spreadsheet gets corrupted.

The change fixed the problem some found uploading ZIP files (including
myself) but this new problem persists.

thanks,
Darryl

Hi all,

Has anyone else experienced problems with the file upload lately? I'm
finding that uploaded files are being corrupted. It doesn't seem to matter
what type the document is. I've found an Excel spreadsheet and a Word
document that have displayed problems. It seems, doing a binary compare,
that a 0A is being inserted arbitrarily. I'm looking at
MultipartIterator.java as the possible culprit as that's where a 0A ('\n')
is being inserted.

If anyone can point out the error of my ways I'd appreciate it. I don't know
why we're only finding this problem now since we've been testing uploads
regularly. Unless it has to do with the fixes in 1.0 final that maybe broke
something. I'm a little out of my depth here since I'm still fairly new to
the intricacies of Struts.

Hi,
Our solution, using struts, is a mutli-page and multi-channel solution.
It works on the principle of page numbers and has only one action per
wizard regardless of the number of pages involved.
There is a base class form which has a validate method that can validate
any form in a generic method, validating only the fields on the current
page, and after completion  of the wizard does a "finalValidate" check to
make sure nothing remained unvalidated (this is necassary due to the
dynamic way in which the page by page validation is executed). In our
system we have a data dictionary most fields represent a field in the data
dictionary - this link to the data dictionary which performs the validation
for that particular type of field e.g. a PostCode validator. The data
dictionary also returns the possible values for fields which are of a
select variety - the labels are then looked up based on the current
language, the field type and the value. If a field is not representing a
data dictionary member a localValidator must be written in the form object

run at the correct time (one of the tough bits!).
The base class Form (which extends ActionForm) is then subclassed, one per
wizard, the member field objects are defined in the initialise method, the
fields have objects which have attributes and methods as necassary to
complete the functionality. The getters and setters in the wizard form
fetch the correct field from the collection and set/get the value to return
to the struts tag libraries/other code.
Each form is then sublassed once per channel (Wap, HTML and iDTV - all of
which we have working). The subclass specifies to the field objects which
page each field is on for that particular channel, this enables the
validation to work correctly and also means business validation errors from
the EJB container after wizard completion and submission can be directed to
the correct page for display. The sublassed channel specific form can add
extra fields and specify which page they lie on (or set a field to be
internal). An example of this is that the base class of a transaction may
contain a single date field. On the Web channel this is actually 3 fields
(day, month, year) on the Wap channel this is just a selection of
today/tomorrow etc. As each page is submitted a method on the channel
specific sublass called mapData is called - in the Web channel this maps
the 3 fields into the 1 date field, on the Wap channel it maps todays date
or tomorrows date into the base class single date field. The validation is
then run and any errors are displayed by including the error tag to the
base class date field (although a mapError method could be called to map it
to the year field in the web channel etc.). When a form is prepopulated

Hi,

Our solution, using struts, is a mutli-page and multi-channel solution.

It works on the principle of page numbers and has only one action per
wizard regardless of the number of pages involved.

There is a base class form which has a validate method that can validate
any form in a generic method, validating only the fields on the current
page, and after completion  of the wizard does a "finalValidate" check to
make sure nothing remained unvalidated (this is necassary due to the
dynamic way in which the page by page validation is executed). In our
system we have a data dictionary most fields represent a field in the data
dictionary - this link to the data dictionary which performs the validation
for that particular type of field e.g. a PostCode validator. The data
dictionary also returns the possible values for fields which are of a
select variety - the labels are then looked up based on the current
language, the field type and the value. If a field is not representing a
data dictionary member a localValidator must be written in the form object
name e.g. validatePostCode. CrossFieldValidations are executed in a similar
manner and we have added functionality to ensure crossFieldValidations are
run at the correct time (one of the tough bits!).

The base class Form (which extends ActionForm) is then subclassed, one per
wizard, the member field objects are defined in the initialise method, the
fields have objects which have attributes and methods as necassary to
complete the functionality. The getters and setters in the wizard form
fetch the correct field from the collection and set/get the value to return
to the struts tag libraries/other code.

Each form is then sublassed once per channel (Wap, HTML and iDTV - all of
which we have working). The subclass specifies to the field objects which
page each field is on for that particular channel, this enables the
validation to work correctly and also means business validation errors from
the EJB container after wizard completion and submission can be directed to
the correct page for display. The sublassed channel specific form can add
extra fields and specify which page they lie on (or set a field to be
internal). An example of this is that the base class of a transaction may
contain a single date field. On the Web channel this is actually 3 fields
(day, month, year) on the Wap channel this is just a selection of
today/tomorrow etc. As each page is submitted a method on the channel
specific sublass called mapData is called - in the Web channel this maps
the 3 fields into the 1 date field, on the Wap channel it maps todays date
or tomorrows date into the base class single date field. The validation is
then run and any errors are displayed by including the error tag to the
base class date field (although a mapError method could be called to map it
to the year field in the web channel etc.). When a form is prepopulated
from stored records before the user begins to complete it a mapInitialData
method is called - in the web channel this would pre-populate the
day/month/year fields based upon the date value in the base class - the
reverse of mapData. We have many more obscure mappings as well as simple
date ones.

There is an ActionMapping per channel for each transaction and as well as
having keys for when the Action has completed such as success, home, error
also have entries, one per page of the wizard like this . Using this we have
host of methods on the form (although these might be better located on an
ActionMapping sublass) which are all used in a completely generic and
centralised way (in the ActionClass we created by extending the Action
class) page flow is controlled using methods such as getCurrentPage,
getNextPage, isLastPage, getNextPageActionForward, etc etc.

The benefits of this design are that no matter what channel is running, you
can be sure that a transaction will always be validated in one way and be
represented by one form. If the channel has a different way of completing
the same form, but to the same end, all you need to do is model the
differences in a subclass. This means extra channels can be added
*extremely* quickly, as all that needs to be created is an ActionMapping
and small Form subclass per transaction. Another benefit is that all page
flow is controlled only by data from the ActionMappings and only via
generic methods in base classes - so there will never be any hunting around
looking for hidden directives. Also all valida

Regarding your proposed solution#2, design a mother

RE: Handling Multipart forms (sort of Wizard)

[Darryl Pentz]

Well I don't know if this is conventional, but what I've done is to add an
attribute to the form, say 'action', and to add action as a hidden field in
the form. Then assign it a different value on each form... in your case
maybe 'education', 'experience' and 'general'.



Then in your validate() method check what the action field is set to and
only validate the fields on that form.

Simple.

Hello All,

I am using mulipart forms for adding an employee information.
In this I have 3 forms namely, emplEducation, emplExperience, emplGeneral in
separate JSPs.
In this case, I am using only one form bean for all these JSPs and only one
action class.

My problem is how to validate the Form bean after each page submission:



I know the validation can be done in the form bean using validate() method
or in

But, if user filled emplEducation form and press "Next", to go to

RE: File Upload Corrupting Zip File

[Darryl Pentz]

The file it errors out on is an image .GIF file. The ZipException is:

java.util.zip.ZipException: invalid entry size (expected 18861 but got 18862
bytes)
at java.util.zip.ZipInputStream.readEnd(ZipInputStream.java:355)

so it's throwing an extra byte in there during the upload. Unfortunately I'm
working on Win2000 right now and my DOS fc utility doesn't do a good job of
telling me what the errant byte is. Basically I know it's exactly one byte
longer.

Do you have a binary diff utility that you could use to see what changed in
the uploaded file? That would be very helpful.

Also, if you can tell me how many bytes were added to the file, and what
type of file it was that caused the problem, that might help too.

Thanks.

File Upload Corrupting Zip File

[Darryl Pentz]

Hi all,

Something happens to corrupt a file I'm uploading from a multipart form. If
I run a ZIP file through my unzip utility targeting the actual ZIP file, it
unzips just fine. If I point my unzip utility at the temporary file in the
deployments temp directory of Orion Server (the app server I'm using), the
utility fails with a ZipException indicating it expected x bytes but got x+
bytes on one of the zip entries.

I did the same with WinZip and it worked on the original ZIP and also failed
on the uploaded temp file. It seems to me that the problem most likely lies
with Struts, particularly the DiskMultipartRequestHandler.java but there's
nothing in there that appears suspicious. Does anyone have any insight on
this or has anyone perhaps had this same problem?

Interestingly though, I unzipped the file, removed the entry that was
causing the problem, rezipped it and everything worked fine. That doesn't
however exonerate Struts however, since both my zip utility AND WinZip
worked on the original ZIP. The problem only occurs after Struts has
uploaded the file.

Here is the output that WinZip gave me when it failed to unzip the temp
file:

Extracting to "C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\"
Use Path: no   Overlay Files: yes
warning
[C:/orion/application-deployments/wellcert/wellcert-web/temp/strts34531.tmp]
:  extra 1 bytes at beginning or within Zip file (attempting to process
anyway)
Error in file #1:  bad Zip file offset (Error local header signature not
found):  409756
(attempting to re-compensate)

Error: unexpected end of file encountered

thanks in advance,

Dynamic Error Messages

[Darryl]

I can't figure out how to return dynamic error messages in the ActionErrors 
collection. In other words, if an exception is thrown in an
Action object, I want to use the e.getMessage() to get the message description and use 
that to populate an ActionError. The ActionError
class doesn't seem to have a constructor that supports this. Help!

Re: Session invalidate()

[Darryl]

Sorry all. Please ignore my previous post. My assumptions were completely
wrong. You can use invalidate() since mapping variables are in application
scope, and in fact I had already put an invalidate() in my code which was
why the second invalidate() I added was throwing an exception.  Sorry
about the brainfart.

Session invalidate()

[Darryl]

Hi all,

Quick question about session.invalidate(). I created a login management
framework that works fine but for one problem. When I introduce the
session.invalidate() command for when the user logs out, naturally, all
the Struts-required beans in the session are destroyed so a
mapping.findforward("success") will also, naturally, fail.

Given these obvious consequences, surely someone out there has dealt
with this before. How does one invalidate a session without hozing all
your Struts objects placed in the session... or better put, how does
Struts implement session invalidation.

thanks,
Darryl

P.S. I did search the archived messages that I have but couldn't find
anything dealing with this topic.

Re: Resources.properties -> trick?

[Darryl]

Mark,

One scenario would be when I'm doing some prototyping and I don't want to necessarily 
setup an ActionServlet to do some quick form designs etc. I might however, want to 
quickly play around with the page parameters using a properties file.

This is in fact the scenario in which I find myself right now. I'm POC'ing a 
template-based framework and I wanted to do a few screen prototypes but couldn't get 
the properties file stuff to work, hence my initial note. I didn't want to implement a 
separate solution as you
suggested I should do before I could determine whether or not something existed within 
Struts to do the same.

Thanks nonetheless for the responses.

I think Mark has probably identified your problem correctly. Mark, any idea how to use

Re: Resources.properties -> trick?

[Darryl]

Michael,

Looks like you're asking basically the same thing I was asking in my note
titled: "Bundle attribute for bean:message tag???"

The reason you're getting that error is that the MessageResources object has
not been initialized and placed in the session (page?) context under the key
"org.apache.struts.action.MESSAGE". It seems like you have to actually use the
ActionServlet to get this to happen. There's probably a way that one can hack
around this and instantiate it programatically at startup but I was hoping
there was some way Struts can do this already without me having to do a hack
solution.

Hopefully someone in the group will respond to our problem.

thanks,
Darryl

Bundle attribute for bean:message tag???

[Darryl]

Hi all,

I'm wanting to use the  tag in an application where
I'm not using the ActionServlet and therefore, not setting up the
servlet specs in my web.xml file. Currently when the JSP page executes
the  tag it tells me:


 javax.servlet.jsp.JspException: Cannot find message resources
 under key org.apache.struts.action.MESSAGE


I thought I could fix the problem by specifying the bundle attribute of
the MessageTag class and setting it to the location in my
CLASSPATH where the properties file resides but it still doesn't find
the file. I have specified the file with a .properties extension and
double-checked that it is in my CLASSPATH at the specified location with
the name ApplicationResources.properties.

Any ideas? Anyone run into this before? I did search the messages I have
stored as well as scoured the Struts website but couldn't find anything
on this matter so I hope I'm not repeating something that was dealt with
previously.

thanks in advance,
Darryl

Re: Newbie Problem solved with hack, but not ideal

[Darryl]

I searched the newsgroups and found that a number of you have already
encountered and commented on this issue so my apologies for not determining
that before I posted my previous note.

I found I did fix the problem by removing the DTD from struts.jar and placing
it separately in the classpath. This is unfortunately a hack but I'll have to
go with this for now until Orion fixes it... or is it necessarily an Orion
bug? I found one posting that indicated that if you change some Struts code,
it also fixes the problem.

Olli Poyry notes that in ActionServlet.java, if you replace (~line 881):

URL url = this.getClass().getResource(registrations[i+1]);

with:

URL url = getServletContext().getResource(registrations[i+1]);

the dtd is found and everything works. My question is, should Orion work
regardless or would it be better to change Struts as indicated above?

Comments from anyone?

thanks,
Darryl

Newbie Problem with Struts Configuration, I think...

[Darryl]

Hi all,

I was wondering whether you could look at this stack trace below and see
if you
see anything that you've encountered before. I'm running Orion Server
1.4.5 and I wouldn't expect there to be a problem with JNDI. (see stack
trace line re: unknown protocol: jndi)
They (Orion) don't specify any setup needed for JNDI to be running as a
service. Furthermore, I've checked the struts-config.xml and it
seems fine. I've pasted it in below the stack trace.

I'd appreciate any help you could offer because I've been wrestling with
this thing for some time now and can't seem to find any
problems. My JSP form action works the same (i.e. breaks) whether I'm
using 'login.do' or '/login.do'.

thanks again,
Darryl

ActionMappings

[Darryl]

Hi all,
I'm a relative newbie to Struts. I'm developing a reusable login component
and have just got it packaged into a WAR file today in order to test. Unfortunately
I'm getting the following error when trying to pull up the default JSP
page that has a few form: struts tags in it.
 
500 Internal Server Error
javax.servlet.jsp.JspException: Cannot find ActionMappings or ActionFormBeans
collection

As you can tell, I'm running under Orion Server. Has anyone encountered
this error before? If so, please let me know what I'm doing wrong or where
I'm going wrong. Any feedback would be appreciated.
thanks,
Darryl
