Re: still fighting HTTP HTTPS problem

[Jonathan Asbell]

Mike.  Dude.  That IS the way to do it.
1) check to see if you ACTUALLY GET the 2 sessions (if you can get them, do
a session.toString() to see that they are not the same session indeed)
2) you should be sending the serialized data from the unsecure session into
the secured session:
if you are using an non visual jsp to process it would go something like
this
a) get the query string and hold it
b) get the data you want from the non-secure session, includeing the session
id and encode it
c) make an name value pair for the session stuff and dont forget to encode
the value (unsecure_session_contents=thedatayouareholdingfromthesession)
d) add the new name value pair to the query string you are holding
e) forward the whole shebang to the secure url you are going to.
f) on the secure side get the request and put the
request.getParameter(unsecure_session_contents) into the new Secure session.
g) do the same for the return trip, but remember when you return you have to
try to look up the session with the id you saved.  If its gone its because
you timed out.

Re: XML Data out of a property into an XSL Transformation by JSP-Tag

[Jonathan Asbell]

You can use the ActionForward to send you to a jsp page which contains a tag
(or tags) which do any one of the following:

1) A Tag/Action calls business objects which in turn get xml, transform the
xml using a stylesheet, and slaps the resulting html in the space where the
tag sits on the jsp page

2) A Tag/Action calls business objects which in turn get xml, transform the
xml using a stylesheet, puts the result in a bean which is retrieved by the
Tag/Action

3) A Tag/Action calls business objects which in turn get xml, puts the xml
result in a bean which is retrieved and iterated over by the Tag/Action

4) Tag/Action calls business objects which return return xml, which is
transformed on the Tag/Action level using a stylesheet

The point is:
You can start with xml and stay with xml up to the web layer and do
transforms there
You can start with xml, transform in the lower layer, and send html up to
the web layer
You can start with regular string data, make a dom, and send it around (I
dont recommend this)
etc. etc. etc.

>From experience, I recommend that if you are actually going to need to work
with xml, DONT USE STYLESHEETS, but rather make "model" objects from the xml
which you can iterate over.

Re: Donating Xml Configurable Character filter

[Jonathan Asbell]

look at it closer Jeff.  It does not touch the escaped url string itself,
but rather the actual characters de-coded from the url using the decoding
you specify.  Also, you decide the appropriate mapping.  Go to the xml file,
make your own mapping, and call it instead of the one I did called "resume"
or whatever it is.  It just stores as many named mapping schemes you like,
and you call the one you want.

Request from contributer user.....

[Jonathan Asbell]

Hello all.  I am still only a few months 
playing with struts but I would like to ask if you wouldn't mind 
putting more detailed debugging in the framework.  I personally am 
studying the framework by reading about it, but most importantly by watching how 
it performs step by step.  I do this by adding the same type of statements 
as yours, but if you set a debug level of 5 it gives you a step by 
step view of what is occuring.  Could you consider this.  It is 
because it is hard enough to understand a framework when you really cant see 
exactly what is happening.  But it is a nice framewor ;^>

Re: Resources clarification - is there a work around

[Jonathan Asbell]

Thanks Pete.  However it just seems strange that Struts just offers one big
resource file for each Local.  I have developed 3 international sites, and I
can safely say that when a set of resources are associated with a particular
page it is much easier to manage than 1 resources for all pages.  Has anyone
hacked at the Struts code to get around this?  I dont like the concatenating
idea because it is too easy to have duplicates; and you probably want to use
the same resource names anyway to keep a consistency.  Anyone else have any
ideas?

Struts status items list /\/\/\

[Jonathan Asbell]

Can any one of you put together a list? We need to 
know:
1) what can currently be thrown out (assuming I 
have the most recent evenings build)
2) what are, and where can we obtain all 
of the recently contributed pieces which are under consideration, being worked 
on or tested (the Token mechanism submission, the iterate patch, the message 
patch, validation, bean factory, auto beans,  etc. etc. etc.)
3) what is next item that has been decided but has 
not been included in any nightly build.
4) what specific areas are we 
currently looking at to solve 
 
Just a brief list for the rest of us to have an 
idea of current state and the direction in the near future.  It will 
effect what we are personally building.
 
Cheers.

Credit card validation FYI

[Jonathan Asbell]

You all probably know about this but I thought I 
would send it anyway.
 
http://www.beachnet.com/~hstiles/cardtype.html
 
MOD-10 is an algorithm that is used by almost any 
credit card company togenerate / validate credit cards.How it 
works?First you have to know what kind of credit card you have.You can find 
itoutby looking at the first(leftmost) number of it.This is what 
itmeans:3= American Express4 = Visa5 = Mastercard 
etc.The algorithm goes as follows : go from right to left and multiply 
everysecond digit by 2.If the result of themultiplication is greater 
than 9 , subtract 9 from it.(ex. if 16 then 16 -9 = 7).Thenn add the result 
to the sum.All other numbers of the card don't need to be multiplied , just 
add themto the sum..When on the end (sum mod 10) = 0 ,the card is valid.In 
otherwords it means that the sum must be a multiple of 10 
(10,20,30).Example:5 4 2 4 1 8 0 0 2 6 7 6 9 0 0 
5---1+4+4+4+2+8+0+0+4+6+5+6+9+0+0+5 = 
58This card of course isn't valid because the sum (58) isn't a multiple 
of10.How to generate cards?Well if you want to generate 
cards , you first have to decide what type ofcards.If you would decide for a 
Mastercard, then the first number would bea constant of 5.Therefore we will 
have to go from left to right to generatecards.The sum will have a value of 
1 on the beginning (see example).Thengenerate random numbers up to the 15th 
digit.Like described above, multiplyevery second number and add all results 
together to a sum.Then calculatethe last number (checksum): if sum is a 
multiple of ten, then the 16thnumber (checksum digit) will be 0.Otherwise 
substract the sum from the nexthighest multiple of 10.In the example 
above we would say : 60 - 53 = 7.Therefore the last digit is7 and not 5.You 
could do that in pascal by saying : last_number:=10 - (summod 10) ;Now 
someone might say that he could generate as many cards as he wants andcould 
misuse them.But that's not the truth.Many online verificationservices will 
also check your user info and expiration date with your bank,which of course 
can't be generated by this program.I've however heardmyself that there are 
many small companies(XXX - sites,Online downloads)which still use only 
MOD-10 scripts for validation.

Re: newbie to struts - confirm hierachy( packages - webapps)!!

[Jonathan Asbell]

I decided to NOT use the Struts.jar, but instead 
use the Struts source files, and then add my own directories below the classes 
directory for that particular web app.  That way I could tweak Struts and 
have a better way of replacing updates to the classes.  My setup is like 
this:
1) Struts framework - /struts/org/apache/struts 
etc... with my classpath pointing to /struts

question about Action Forwards in struts-config

[Jonathan Asbell]

I have boiled down action forward to a few exact 
situations.  I would only want to do any of the following 
situations:
1) take me back where I was
2) take me back to where I was trying to 
go
3) take me to a specific page
4) take me to a default page
 
I dont believe there is currently a neat and clean 
way of describing this in the struts-config.  Maybe there doesnt need to be 
for things like "where I was trying to go" and "where I was".  I am just 
looking for some clarity on the issues and what/why the implementation is what 
it is currently is

uploading file requires immediate serialization location?

[Jonathan Asbell]

Hello all.
I am just trying to understand an aspect of a 
multipart request.  When you submit after using an input of type "file", do 
you have to provide an immediate location for the file to be serialized to, or 
can you store it in a java object (in a bean's field) as a binary object until 
you are ready to serialize it.  The reason is that I want to hold a jpeg in 
a bean until the person completes the last page of the form, and THEN serialize 
it.
 

Re: uploading file requires immediate serialization location?

[Jonathan Asbell]

Hello Martin.  So is it POSSIBLE to save binary data in a bean?  What does
struts do?  These are my real questions.  If I have a form which besides
fields, has an uploaded file, how does the bean actually handle the file?
Is there a conceptual step by step you can give me.  How does the ActionForm
save (and validate) the binary data sent via input type "file".

Missing configuration resource for path /WEB-INF/struts-config.xml

[Jonathan Asbell]

I am not sure why all of a sudden I am getting this 
Exception on startup
=
Call 
org.apache.struts.action.ActionServlet.addServletMapping(action/java.lang.String,*.do/java.lang.String)javax.servlet.UnavailableException:

 If you see the ActionServlet code below, I am getting 
"/WEB-INF/struts-config.xml" as the value for the handle "value", yet  am 
getting null for the value of the handle 
"input".  For some reason it is unable to get the 
"/WEB-INF/struts-config.xml" resource as a stream
 
 
 // Initialize the context-relative path to

getServletConfig().getInitParameter("config"); if (value !=

Re: uploading file requires immediate serialization location?

[Jonathan Asbell]

Martin, you seem to understand this subject well, so let me take a shot and
tell me if I am correct:

A multi-part request is a request, but a different one.  That is, with a
regular request things have been abstracted for us nicely with
"getParameter" etc., but a request submitted as multipart is not handled
nicely for us by the servlet spec and is a whole different animal.  This
type of request needs to be handled uniquely (though I dont understand why
the servlet spec does not have standard abstractions for it), because it may
contain binary non-text content accompanied by regular content.  In such a
request we need to examine the sections in the header and parse for certain
values we are expecting to separate out the regular text values submitted
from the binary parts, and then handle the binary parts.

Things I still dont get:
In all packages I have examined that handle multipart requests, there is
always a notion of looking for the line ": ", then looking for the blank
line after that, and then reading in binary values that follow the blank
line up until the "boundry" which is a String in a known format (see link
below).  What I dont understand is what are our options in handling this
binary stuff which is not text.  Most packages I have seen write it to a
file.  I'm not sure if there is a way to save a binary object at all, let
alone save it in a filed value in a bean.  How do you store a binary object
in a field?

Mixing a multipart form with beans

[Jonathan Asbell]

If I have a 5 page "wizard" (five consecutive 
form pages) and one bean, where the first three forms are regular requests and 
the fourth and fifth are each multipart forms, how do I use a bean with these 
pages?  Do I:
1) fill bean with the form values from page 1,2 and 
3 ?
2) then for the multipart forms on the last 2 pages 
fill the bean with the regular String values while simultaneuosly writing the 
file to disk but dont submit the bean filled with values until the last 
page?
 
Should I bother setting the "name" value in the 
bean for the form input of the file?  Do I need to do any validation for 
the file item?
 
The way I see it is that there are request values 
that I need to get from the request which are NOT binaries, and I need include 
them in the bean.  However, I am guessing that I should write the file as 
soon as possible to disk and NOT store it in session.  The question remains 
as to exactly when I am submitting the bean and its values.  At the same 
time that I am writing the file to disk?  Eariler? 
Later?

Re: uploading file requires immediate serialization location?

[Jonathan Asbell]

So do you simultaneously write to a file while reading a String parameter
when you process a form?  What parts of the multipart request do we save in
the bean, and in what scope?

Re: uploading file requires immediate serialization location?

[Jonathan Asbell]

You wrote... "The uploaded data is stored in a temporary file somewhere on
disk.The bean is in either request or session scope. If the bean
goes away, then so does the file that holds the uploaded data."

I thought you said the file was written to disk?  Thus the binary is not in
the bean.  Or is it that the FormFile has all this data and IT is in the
bean.  So I end up with a file on disk that is in a state of not be
associated with anything yet, and whos filename and input field names I have
lost when the bean went away.  Is that it?  If we are keeping the FormFile
in the bean, in the session and the FormFile indeed does contain the binary,
than this is a bad thing.  We should at theleast kill the binary from the
FormFile object so we CAN safely put it in the session.  (Dont know if I
mentioned by weblogic croaks/freaks if the session has too much "k" in it.

perform() method you will make calls and get results.  But where do you put 
the results?  Do I save the data to a bean which I pass in the request to a 
waiting Tag class on the page I will forward to, and have that Tag class iterate 
through the beans data? This means I have to make Tag classes to read 
in passed beans. 
 
How are you all doing this in general.  I am 
very interested.

  I would definately not recommend 
  it.  The MultipartRequestWrapper object is 
  something that
  should be 
  used internally to Struts, to work around some existing issues 
  between
  normal and multipart 
  requests.  Also, that class is definately going to change to 
  extend
  javax.servlet.http.HttpServletRequestWrapper when 
  Struts adopts the Servlet 2.3 spec.

  when the user  submits   the whole "kit and 
  kaboodle". 
   
  Instead of doing this, 
  you'd probably just want to stick to using an ActionForm bean that 
  has
  a FormFile 
  property.  The FormFile interface should suit your needs well, 
  as it has a getFileName()
  method and methods to 
  retrieve the data written to a temporary file after 
  uploading:
   
  public 
  class MultipageForm extends ActionForm 
{
   private FormFile 
  theFile;
   
   public void setTheFile(FormFile file) 
  {
    this.theFile 
  = file; 
   }
   public FormFile getTheFile() 
  {
    
  return theFile;
   }
  }
   
   > Part of the 
  problem is that I dont understand what is going on. It looks like the 
  request keeps the following:
   > "name" property 
  representing the form field name
   > "value" 
  property representing the String path of the file you 
  uploaded
   > some binary 
  Stream data representing the file 
   
  Again, don't pay much 
  attention to the MultipartRequestWrapper class, concentrate on creating 
  an
  ActionForm bean 
  that has a org.apache.struts.upload.FormFile property representing your 
  file, and
  normal String 
  properties representing your form data, just as you would normally create a 
  non
  multipart 
  form.
   
   > I realy have no 
  idea, and I am looking around for answers but am coming up 
  empty.
   > Can someone sum 
  up what is happening here, what the request contains, what values the 
  request 
  > works with, and 
  what   are the requirements. 
   
  Martin Cooper summed 
  this up nicely in another thread about uploading, but I'll go 
  over it anyway:
   
  1) Request comes in, 
  Struts goes to populate the form (BeanUtils.populate()) discovers 
  that the
      
  content type of the request 
  is "multipart/form-data"
  2) Struts goes to 
  populate the form, and creates a MultipartRequestHandler instance to 
  handle
      the multipart request.  
  MultipartRequestHandler is an interface, the implementation can 
  change
      at will and can be specified as an 
  init-param for ActionServlet, or as an ActionServlet 
  property
      in 
  struts-config.xml
  
  2a) In the 
  implementation that comes with Struts, the multipart form data is read as 
  follows:
    Read the 
  data,
      if it's a 
  string parameter, grab it's value and put it in a Hashtable for later 
  use
      if it's a 
  file, read the file with a BufferedInputStream and store the data in a 
  temporary
      file, then 
  wrap it in a FormFile implementation 
  (org.apache.struts.upload.DiskFile)
      and hand 
  it back to BeanUtils (next step)  
  3) 
  BeanUtils.populate() uses the interface methods in MultipartRequestHandler to 
  grab the properties
      that were retrieved from the 
  normal multipart request, the populates your ActionForm bean with 
  the
      relevant 
  data.
  4) The 
  Action is executed, and code in there manipulates the file according to 
  whatever you want to
      do with it, for example, say we 
  wanted to take the previous form bean (above) and use it in the 
  action:
      
  public class 
  UploadAction extends Action {
      public ActionForward 
  perform(ActionMapping 
  mapping, ActionForm 
  form, 
  HttpServletRequest 
  request, 
  HttpServletResponse response) {
     
  FormFile theFile = ((MultipageForm) form).getTheFile();
     
  String filename = theFile.getFileName();
     //and 
  so on...
  }
   
  Hope this helps, also consult that long thread 
  called
  "uploading files requires immediate serialization?", 
  Martin Cooper does
  a damn good job of answering questions about 
  this.  Thanks again Martin...

Re: Handling Multipart forms (sort of Wizard)

Hello Mike. Cant this be done neatly with one action form?  I wouldnt want
to create 3 form beans because if the designers move some form fields to
another page, than I have to change the beans effected.  You know what I'm

Re: General Struts & J2EE question

Ted, One thing I am not understanding is why we are bouncing requests all
over using various servlets, as in the case of validation.  What are the
consequences and or benefits of one servlet triggereing another etc.  It
seems as though this can create confusion because you dont know what is
happening.  That is, you could end up being bounced all over the place from
servlet to servlet beforwe coming to a rest, and you may or may not know
what exactlly transpired.

Type conversions - issues on where to do them

[Jonathan Asbell]

Hello all.
I wanted to know where you are doing type 
conversion.  The reason I ask is because to some extent one may choose to 
do slightly deeper validations in the ActionForm for reasons of 
expectation.  The question remains as to the exact level of "light" 
validation we should do in the ActionForm.  From reading the list it seems 
the general consensus is to only do validation of a value's existance.  
However, where do you do type conversion then?  In the ActionForm? In the 
Action?  In the BusinessObject layer?  The issues are:
 
1) If I do it in the ActionForm and there is a 
problem in the Action, then I have to reconvert back to a String on the way 
back.;
 
2) If I do it in the Action, same problem, but also 
the argument has been brought to my attention that the ActionForm bean (although 
temporary) does not truly represent the data it contains (like when a value 
 represents a double, money, or a Date)
 
3) If I do it in the Business Layer than 
the message has gone deeper into the application than necessary which 
sacrifices performance and needless use of resources.

Re: General Struts & J2EE question

[Jonathan Asbell]

Ah.  So you are saying its just a plain class(not a servlet).  Or rather,
its not being triggered by urls, but rather by direct calls from other
classes. Or is it a servlet that is not being triggered by urls.  I am just
getting confused because it is the umteenth time I have seen these pluggable
"extensions" referred to as servlets.

Re: Type conversions - issues on where to do them

[Jonathan Asbell]

Well, just one hitch when doing the business validation in the Action.  If
you are developing in an enterprise environment, you probably want to do
these kind of validations in a business object because, as pointed out in an
eariler thread, you may need data from the database to do this
validation/evaluation.  Better that the validation for this level all be in
one place.  In an enterprise app the Action would probably be considered
part of the web tier.  Therfore, it would not be good to mix the two tiers.
What do you Think?

By the way Ted, thank you for being so open and taking the time to offer
your perspective.  I really appreciate it and I'm sure everyone on the list
does as well.  It makes this list truly worth while. Ditto to Oleg, Martin,
Michael, Johan, Peter, Nanduri, Jon, Jeff, Hal, David, and Craig.  I have
learned alot in these 3 months.

Re: Type conversions - issues on where to do them

[Jonathan Asbell]

Regarding your answer:
"Of course, you need an 'it can't happen, but it did' sort of error catch
for conversion errors when you copy the String versions of the properties to
your actual business objects, "

Are you assuming that I keep the form data as Strings until the business
layer? This was my collegue's complaint about the ActionForms because they
did not contain the "types" he was expecting, but rather just Strings. Where
are you personally doing conversions?

Re: Type conversions - issues on where to do them

[Jonathan Asbell]

As we are both being nightowls in the same timezone, let me continue with
this.  We are using a Broker.  So, in my case each Action would call the
Broker, which is our link to the enterprise layer. Also, if the business
object rejected the data, as you said, than it would pass it to the Action
but NOT up again to the ActionForm.  At that point the Action would choose a
forward with errors and data.

Re: Extending ActionServlet

[Jonathan Asbell]

Why dont you do what ANT does?  You can include an external reference inside
the struts-config which acts like an include.  Digester will parse
struts-config.xml which will have external references to your external xml
fragments.

Re: [EJB] Design Patterns (was JavaReport ...)

[Jonathan Asbell]

I was on this track in another thread where I was saying...

"What if ActionForm was an inner class to a Value object.  Or, what if a
Value object had a reference to an ActionForm which when filling with
parameters we did ActionFormValue.getActionForm(), filled it, complete "does
it exist" checking and non-business object validation checking, and then do
a ActionFormValue.setActionForm(ActionForm myform) to set it back, which
would fill the ActionFormValue object with the values in the ActionForm. An
"ActionValue" could hold 1 or more ActionsForm(s) , or could take ActionForm
as a parameter, with which it would copy and "nativeize" the data in the
ActionForm.  In this case an ActionValue would hold specific fileds for the
beans it uses."

My point here,though I hope it is apparent, is that we need to send
value ojects through the system in a way in which it can complement/work
with Struts.

Re: [EJB] Design Patterns (was JavaReport ...)

[Jonathan Asbell]

What you have here is:
1) an immutable from the web tier
2) an immutable from the enterprise tier
3) a need to update each other

Maybe they are immutable as far as standard get/set methods.
However, they can also implement an interface which uses separate secondary
fileds which start with the original values, and CAN be updated.  In this
way the 2 original models (the web tier ActionForm and the EJB model) can
have the original values untouched, and the new secondary fields will hold
and provide the updated state.

Re: digester.addSetProperties("elemA/elemB");

Because it parsed it:

this
&<"
parsed becomes
&<"
after parsing. And the parser WILL parse it because it is an attribute. So,
if you want to end up with

Implementing 2 new scopes using Struts

[Jonathan Asbell]

I will be implementing new scopes using Struts for 
our unique needs, and they need to be application server 
independent.  
 
One scope will work 
across (between) web-applications:  Ex. user logs on, and an object 
representing the users values and state is placed into a scope where ALL WEB 
APPLICATIONS can see it.
 
Another scope is restricted 
to specified directories inside of an application:  Ex. data saved 
would only be visible when inside a specific sub-directory.
 
I am currently examining 
the 2.3 servlet spec.  Does anyone have any advice as to what to watch out 
for in implementing this considering I want to be able to be compatible 
with servlet containers in general and leverage container management and web.xml 
configuration.  Could anyone refer me to some specific sections in the 
servlet spec that you feel I should pay specific attention to while I am doing 
this. 
 
Thank you

Re: Implementing 2 new scopes using Struts

JNDI is expensive.  Then second one is a

Ex. I have a web app called myWebApp, which has its own WEB-INF directory 
with a web.xml inside. Below myWebApp I hav 3 directories called Jon, 
Nanduri, and Ted.  I want to store things that pertain to the Jon branch 
which neither the Ted branch nor the Nanduri branch can see.

Re: Submitting unicode characters from form fields

[Jonathan Asbell]

You must configure your web application to DECODE the utf8 encoded stuff.
In weblogic I make this entry in the web.xml file:



weblogic.httpd.inputCharset./*
UTF-8



I'm not sure what you need for tomcat configuration

QUOTING AN E-MAIL FROM HANS BERGSTEN

8859-1 is [currently] the default
encoding of HTTP. When a browser sends a parameter in some encoding, such
as UTF-8, it encodes each character byte value as a hexadecimal string using
the encoding for the page (e.g. UTF-8). At the server, however, the part of
the container that interprets these character values always assumes they
are 8859-1 byte values. So it created a Unicode string based on the byte
values interpreted as 8859-1. In the Servlet 2.3 spec it will be possible to
tell the container to use
another encoding that 8859-1 to interpret the parameter value bytes, but
for now we're stuck with this "hack".

Re: concatenating resources files - in which class?

[Jonathan Asbell]

I think I will do the following:
1) Identify which Locals I am supporting and declare them within web.xml
fr_FR.properties
es_ES.properties
es_EN.properties
en_EN.properties

2) On loading the servlet, for each Local I will search for ".properties"
files and create a FileInputStream for each

3) I will create a target file called "Resources_xx_xx.properties" and read
each file in to it, repeating this for each Local until I have one master
properties file for each local
Resources_fr_FR.properties
Resources_es_ES.properties
Resources_es_EN.properties
Resources_en_EN.properties

Thats it!

attributes in the Bean & Logic tags - Help

[Jonathan Asbell]

I have been looking at the documentation and I am 
still not comfortable with understanding what certain attributes represent in 
the Bean & Logic tags. I am particularly confused 
with nested tags and  these attributes:
 
id=
name=
property=
 
Could one of you kind gentlemen help with a concise 
yet on the money explanation.
I am understanding that the value placed in 
"property" will translate to a getProperty, but I am not sure which bean it 
pertains to?

server.  I am not sure which i-Planet version we have but I will find out 
tomorrow.  My problem is below..
 
 
I am submitting to an Action which FORWARDS 
to a second Action, which REDIRECTS to a third Action which 
FORWARDS to a jsp
 
Action1-(Fwd)>Action2-(Redr)>Action3-(Fwd)>jsp
 
Action 3 never gets triggered because the mapping somehow does not 
match.  When I look to see the mapping the ActionServlet generates at 
that point, it appears that it has calculated the path incorrectly.  I end up at the following URI with the following 
message:

http://localhost:7001/successmtgs/postsecure_jump.do 
Invalid path /successmtgs/postsecure_jump was 
requested
 
The final action should be triggered by path="/postsecure_jump".  The path that is being 
looked up for the mapping is "/successmtgs/postsecure_jump".  
I shouldnt be getting this value because the 
ActionServlet's processPath() method is supposed to
find the last occurence of a "/" [int slash = 
path.lastIndexOf("/");]
So my path to match becomes - /successmtgs/postsecure_jump
instead of - 
/postsecure_jump
Now the mapping is wrong and I wont be able to 
forward
 
 
 
 
HERE ARE MY STEPS
=
step 1 - I am on localhost
http://localhost:7001/successmtgs/index.jsp
I jump to another server via a link
 
step 2 - I am on another server
http://anotherhost:8007/successmtgs/signin.jsp
I submit a form to /process_logon.do
 
step 3 - the servlet is triggered and runs an 
action
path="/process_logon"
this action FORWARDS 
to another action path="/presecure_jump.do"
 
step 4 - this second action is run
path="/presecure_jump"
this action REDIRECTS to another 
action path="/postsecure_jump.do"
 
(dies here..)
 
step 5 - ACTION NEVER GETS RUN BECAUSE "No mapping available for path 
"/successmtgs/postsecure_jump"
path="/postsecure_jump"
FORWARD to 
path="/successmtgs/index.jsp"
=
 
 
 

iPlanet- I'm having the same problem....

[Jonathan Asbell]

Did you see my post last night?  Supposedly 
iPlanet implemented a piece of the servlet spec incorrectly and you need to 
upgrade it with a service pack for the ActionServlets processPath() method to 
get the correct value for request.getServletPath().  Mikkel, send me your 
number and e-mail me at work so we can help each other work this out.

Re: Still struggling with my Iplanet 4.1

[Jonathan Asbell]

make sure struts.jar is in your classpath in kregedit.
 Also, if you have any ActionClass or FormClasses that
you're calling from action, you'll need to make sure
the full path to
\iPlanet\ias6\...\APPS\...\WEB-INF\classes is in your
classpath.  It's a bug in iPlanet, but this workaround
works like a charm.  Let me know if you have any other
iPlanet issues, as I have spent a fair amount of time
getting struts to work on iPlanet.

If a JSP
defines a prefix with the same name as a literal
HTML-tag like html, body, head, etc.,you'll run
into this problem.

E.G:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>

...

Since the code in the JSP is case sensitive, changing
the case of the literal HTML-tags (or the prefixes)
already solves the problem:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>

...



I figured out the problem.  For the interest of the mail archives, the
solution is to use regular expressions in obj.conf.  "*.do" is not enough
for iPlanet (struts documentation should be ammended for this).  I found I
needed to use "*.do;jsessionid*" in addition to "*.do".  This fixed the
problem.  Note: rules.properties didn't seem to work either since the
servlet is running from tomcat, not iPlanet.

Re: Still struggling with my Iplanet 4.1

[Jonathan Asbell]

This is a common problem when configuring struts on weblogic. Reason is that
the parser could not fetch the
file(http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd) from the
web.
The easiest way is to alter the request to your local file.
For example:
FROM:
http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd>

TO:

Struts Documentation (*Ted & Craig*)

[Jonathan Asbell]

I wanted to know what you finally decided on 
regarding my recent documentation submission.  Also, I wanted to know if 
you saw the pictorals and thought they were accurate.
    On a side note, I have been 
struggling with a struts component that seems simple, yet I am stuck and cant 
understand it.  My impasse is in the path matching behavior of the 
servlet.  Has anyone implemented the matching on a path regardless of 
depth.  Like in the digester, where you can match on any "a" tag by using 
"*/a".  I am finding that Struts is forcing me to specify full paths to my 
actions, and that there is no way to get the text matching behavior of the 
Digester or xsl.  Is this the case?

Re: Struts Documentation (*Ted & Craig*)

[Jonathan Asbell]

Kind of.  Below are two messages I sent in which the issue is more explicit:
===
  Can someone tell me if there is a way to configure an action to match
a path regardless of how deep it is in a directory?  That is, I want
"/display.do" to be triggered in each case below:

  "/charts/display.do"
  "/news/display.do
  "/events/outdoors/display.do"

  How can I accomplish this?

===
A potential implementation clarification/development consideration.
If I submit a form action="/login.do", the Action triggered must exactly
match "/login.do" and not partial match.That is, action="/signup/login.do"
will not match.  Now this may or may not be the desired behavior.  You may
in fact want any url that ends in "/login.do" to trigger the specific
Action, or you may not.  It seems that Struts is handling the exact match
case correctly, so it is not a bug.  However, it was not clear to me that
the Action needed an exact match of the full path.  In fact, our
ActionServlet is triggered on ANY url that ends in ".do". and configurable
to be triggered on a more specific path.

Re: requirements for path triggering actions

[Jonathan Asbell]

I think you may have misunderstood the problem.  ".do" IS triggered, but the
Struts mapping object registered under the "path" may not be found.  In
other words consider:

"/charts/display.do"
"/news/display.do
"/events/outdoors/display.do"

I want ANY occurence of  "display.do" in the path to trigger a particular
mapping

Workflow impasse? New ideas.

[Jonathan Asbell]

Hello all.  I just got back and was reading 
the e-mails about workflows.  By the tone and lack of dialog I think that 
we are not sure how we really want to design workflows still.  So lets 
have more discussion on the subject.  When its clearer we will better know 
what we want to do.
 
Here are some ideas I thought could break down 
the problem a little more.  I was thinking that a workflow can be described 
in the following ways:
 
1) It has a specific order
2) It DOES'NT having a specific order
3) It has a combination of tasks, some of which 
need to be executed in order, and others that do not
4) All of its tasks must be finished at the 
end
5) It May be made up of other 
worklflows
 
Therefore, you would get a workflow with the 
characteristics you want.  At the end you would make sure all tasks have 
been done in order it to be considered a completed workflow.  For items 
that need order we can use the struts config file to put an entry in for 


 
  
  
  
 

 
anyone want to add

referring to the DTDs

[Jonathan Asbell]

I was wondering if there is a way for an xml doc to 
look for a dtd in 2 or 3 places.  Can you do this:
 

            "file:///c:/bea/wlserver6.0/config/Wcom/applications/mydomain/WEB-INF/struts-config_1_0.dtd
    "file:///c:/dtds/struts-config_1_0.dtd
        "struts-config_1_0.dtd>
The reason is that I want to refer to the dtd using a 
RELATIVE path on both UNIX and 
NT

Feature enhancement - triggering an Action

[Jonathan Asbell]

This thread appeared on the list earlier this 
week.
 
QUESTION - JonathanCan someone tell me if there 
is a way to configure an action to match a pathregardless of how deep it is 
in a directory?ANSWER - TedNo. There is not a way to do this, 
without changing the way Struts isprogrammed to behave. You could request a 
feature change in Bugzilla, andbring it up on the DEV list for 
discussion.==As 
I was experimenting with our struts app I ran into the situation where 
Iwanted a generic "path-indifferent" name to trigger an action.  
Forinstance, in the following three 
cases:"/charts/display.do""/news/display.do"/events/outdoors/display.do"I 
didnt care about anything except the existence of  "display.do" 
ANYWHEREat the end of ANY path.  In fact, isnt this exactly how the 
servlet istriggered with ".do"  This is what I expected, and the 
current Struts designwont let me do this.  Do you all think this is an 
important feature?  Ireally would like it as it can give a sense that 
the behaviour is common,and saves me time in thinking about how to properly 
trigger that particularaction I was wanting.

We are using weblogic 5.1 and are constantly having issues to resolve with
class loading.  We are NOT placing our /classes and /lib etc inside of the
WEB-INF directory for reasons of simpifying migration from NT to UNIX.
Instead we have the entire application outside of the weblogic directory
starting at the root (C: for NT, and /whatever for UNIX).  Our scripts point
to the correct places so weblogic and the java classloader can find them to
load.  We only have one web application now, however, and will for the
forseeable future.  I bring all this up because we load some classes in
separate class loaders, and other classes are loaded by both!  We need to do
this because of this setup.  I dont know what all the consequences of this
are, but I just read an article about classloading where it suggests using
".ear" files to remedy this classloading issue.  Could you please comment.

how do I get error messages?

[Jonathan Asbell]

I have the below form.  In the ActionForm 
class for this form I am testing for a valid username.  The code is like 
so: errors.add("username", new 
ActionError("error.username.required"));  In my mappings I have the 
response going back to this same page if anything is not valid.  But how do 
I get access the messages in the ActionErrors object using a tag,  I have 
tried  on the same page with no results.
 
    
USER 
ID:    
   PASSWORD:*
    
  

Can someone explain the "path" attribute in action-mappings

[Jonathan Asbell]

How exactly do I implement it?  The doc say 
"The application context-relative path to the action", but this is not clear to 
me.  I am having the same trouble implementing the "input" attribute.  
Can anyone make this clear for me:  What should the value 
be?

Re: HTML special characters

[Jonathan Asbell]

Doesnt this issue depend on the character encoding?  That is, high ascii
values (128-255) are control characters in some encodings, which I assume
you want to get rid of.  Than, there is the 0-31 characters in ascii which
are control characters of which you want to get rid of all except tabs,
spaces, carriage returns, and line feeds.  Than there are characters
reserved for private use in other ranges.  FYI Macintosh has a 0x0 character
which breaks alot of apps, and netscape for mac versions 4.x  have a bug
which introduces control characters on html form submissions.

*** implementing consecutive form validation? ***

[Jonathan Asbell]

If a form is made up of three consecutive pages and 
I want to validate page by page, how should I go about doing this?  Do I 
use three ActionForms and one Action?  Do I use the validation the 
ActionForm offers for basic validation?  Do I fill one ActionForm's 
validation method with "if/then" statements to test if I am on the first, 
second, or third page of the form and then use the Action's validate method at 
the end?
I was interested in what you all were 
implementing.

why does struts use forward instead of redirect

[Jonathan Asbell]

Anyone know why struts uses forward instead of 
redirect?

Displaying dynamic content - html from xslt

[Jonathan Asbell]

Our system submits a request to a jsp page 
which contains jsp tags.  When the request hits the jsp page the tag 
macros communicate with EJB's which call xml from the database, 
run the xml against stylesheets, and slap the output in the places where 
tags were in the jsp page (ie. simply using jsp tags with xml and 
styleshets).  I am interested in using struts to accomplish this for me, 
but I am not sure how to implement this architecture with struts.  Do I 
have an Action object do the call, put the html output I retrieved from the xslt 
transformation into a bean, and then call a getContent() method of the bean to 
place the dynamic content a specific aea on the jsp page?  Do I 
still use custom tags, but within the struts tags?

Can someone explain in more detail the "path" & "input" attribute values of Action

[Jonathan Asbell]

It is not clear to me exactly whatthese values 
could or should be.  I understand that the ".do" is stripped of the 
request, so does that mean I only have to match everything up to the ".do" 
?  Why is a "/" used?  To me this means "root", and in fact in the 
Login example the path changes from "/mysite/logon/logon.jsp" to 
"/mysite/login".  I am aware of the side effects of forwarding on the url, 
but I am confused as to how to employ the "input" and "path" 
values.

Possiblility Answer to: html form widgets not appearing

[Jonathan Asbell]

It sounds like you have a "classpath problem".  I bet you either have a
system classpath (ie a classpath set in your
settings/controlpanel/system/advanced/environmentvariables assuming it
is a pc) which conflicts with the classpath you start up when you run your
server.  Either way it seems that it cant find your file in the classpath to
load.  Try to loop through and print to the console all of your system
variables at the point after you start up your server. (cut and paste class
below)
What you are looking for is the following system properties:
"java.class.path"
"user.dir"
Put your properties in the directory that indicates your "user.dir".  If it
works than your problem is your classpath.

import java.util.*;
public class DisplayEnvironment{
 public static void main(String[] args){
  new DisplayEnvironment();
 }
 public DisplayEnvironment(){
  System.out.println("");
  displaySystemProperties();
  System.out.println("");
  displayWeblogicProperties();
  System.out.println("");
 }
 private void displaySystemProperties(){
  Properties p = System.getProperties();
Set set = p.keySet();
Object[] o = set.toArray();
List l = Arrays.asList(o);
Collections.sort(l);
Iterator i = l.iterator();
  while(i.hasNext()){
   String s = (String)i.next();
   System.out.println(s + " " + p.getProperty(s));
   System.out.println("");
  }//while
 }//method
 private void displayWeblogicProperties(){
 }
}

Re: Reducing the burden on ActionServlet.

[Jonathan Asbell]

Title: Reducing the burden on ActionServlet.



Isnt it true that if you have 10 users you would 
have 10 instances of the ActionServlet?  I believe it is not a singleton 
and that you always have an instance of the servet for each threaded 
request.

  Subject: Reducing the burden on 
  ActionServlet.
  
  In our project we have more than one hundred jsp 
  (each having an average of 2 or 3 forms )and we have already decided to use 
  struts as our framework. Now the dilema :- We found that managing such a large 
  number of jsp from a single stuts-config.xml file will be a huge  burden. 
  Plus, it seems the ActionServlet will be hard pressed always, as a controller. 
  Considering both these facts we realize that there should be a mechanism to 
  share the load of servlet through some way. Though this can be achieved by 
  using more than one servlet , we don't want to use this solution because it is 
  highlt complex considering the projects interwoven functional 
  requirements.Is there some way by which we can accomplish an efficient way 
  to manage a large number of jsp files and to increase the performance by 
  reducing load on the servlet.
  Thanking in advance. 

Re: Possiblility Answer to: html form widgets not appearing

[Jonathan Asbell]

Your right, I read it wrong
Quoting from
http://jakarta.apache.org/struts/userGuide/building_view.html#i18n

"The important thing is for the resource bundle to be found on the class
path for your application. Another approach is to store the
MyResources.properties file in your application's class folder. You can then
simply specify "myResources" as the application value. "

However, what I said is true about the "user.dir" value.  For security
reasons, when using Weblogic, Tomcat etc. , your can not make relative
references to a file from a servlet.  They  have to be absolute, or relative
to the "user.dir".

Lookup performance on ActionMappings

[Jonathan Asbell]

Our company manages almost 100 related sites, 
some with 3 million+ /month viewership.  In thinking about how I would 
approach the ActionServlet I am suspicious that the lookup time of the 
ActionMapping might become unsatisfactory when you reach a certain 
number of mappings.  Does anyone have any statistics?  Would you all 
suggest a servlet for each site in this case?  Keep in mind that all fo the 
sites share the common core enterprise framework.

Correctly using token mechanism

[Jonathan Asbell]

After studying how the token mechanism works, I 
understand the following:
 
1) The token is a unique identifier (value) which 
may be found in the Session and Request, which is used with certain form 
submissions.
 
2) It is created, if it does not already 
exist, by an Action object that wants to use one, and its value is 
subsequently put in the session.
 
3) Its value is taken from Session by and 
used in conjunction with an org.apache.struts.taglib.html.FormTag as a hiden 
form field value.
 
4) When the form is submitted, the token's value in 
the submitted form request is compared to the value of the token sitting in the 
Session.  If they are equal than the Action may be processed.
 
QUESTION 1:  In what situation should we use 
the token mechanism, as it seems that in the Struts example not all form actions 
need it.
 
QUESTION 2:  At what 
strategic point should the token be created for use, as it seems like one Action 
creates it and another Action looks for it and uses 
it?

Re: Suggestion/Idea for tag: Iterate ResultSets

[Jonathan Asbell]

Result sets ARE tied to the connection in a way.  Some DB drivers throw
exceptions when you try to manipulate data while you still have a pointer to
rows.  At work we were trying to manipulate a stream which was pointing to
an output parameter in a stored proc while the connection was open.  The
result was that we had to convert the stream into another object (String in
our case) and close the connection just to manipulate the data.

I hit the same weakness of struts a few months ago and I enhanced some
struts
classes in order to be able for each action to specify which action has to
precede this action. This allows you to implement some kind of control flow.
For
instance you can now define an action that displays a logon page
(displayLogon)
and specify in the next action (logonAction, which gets executed when the
user
presses the submit button of the logon page) that displayLogon needed to be
executed directly before. This is more powerful than the token mechanism.

What I also did at the same time is an enhanced user authentication checking
for
each action. You can now specify a different user authorization class for
each
action, so you can easily implement a very fine grained user authorization.

Exceptions (either control flow or user authentication exceptions) are
handled
by the framework and cause a forward to different error pages.

I plan to propose this enhancement to the struts developer's group after
release
1.0 is out. If you are interested in the meantime I can send you the code.

My understanding is: For request scope you normally do not need to clean up,
because the object gets removed automatically, when the request is served.
For
the session scope you pretty often want to remove e. g. a form bean, when it
is
no longer needed to keep your session data lean.

Struts & Weblogic 5.2 sp10

[Jonathan Asbell]

3 issues
 
1) Maybe the build is bad, but I had to recompile 
ActionForm and put it in my applications classes directory to get rif of 
the "Cannot find ActionMappings ActionMappings or ActionFormBeans collection" 
while using Weblogic 5.1 sp10
 
2)When I forward from a jsp page outside of the 
WEB-INF directory to a jsp page inside the WEB-INF directory, Weblogic tells me 
that it cant recognize the resource "/WEB-INF/mydirectory/myfile.jsp".  

 
3)To access a jsp inside of WEB-INF dont you have 
to have atleast ONE jsp outside of the WEB-INF to start the process.  
Otherwise there is no way to access a jsp.

~~ Confusion with triggering an Action ~~

[Jonathan Asbell]

in my jsp page http://localhost/sports/trivia.jsp I 
have a Struts form 
 
Considering this, the following is 
true:
1) the directory I am currently in is 
"/sports"
2) the request I am submitting to is 
"/processTrivia.do"
 
When I create my mapping inside struts-config.xml 
 the action is not triggered when 
the form submits.  This is because for some reason I have to match to the 
path "/sports/processTrivia".  This does not make sense to me, because I am 
actually submitting to "/processTrivia" inside my form, and not 
"/sports/processTrivia" even though I am actually in the "/sports" 
directory.  When I submit a form to "/processTrivia.do", I expect that it 
will actually submit to "root-slash-processTrivia".  Can someone clarify 
this.  I have mentioned this before and noone seemed to respond.  In 
addition, my collegues also feel this is misleading.  The result is that I 
have to make mapping entries for this action in each level of the directory 
where I want this service.

My default web application is not "/sports", but 
rather just "localhost".  If the site was live the web app would be "http://www.mysite.com", and I would be in the 
"/sports" directory.  What can I do to get the behavior I am 
expecting?

  /processTrivia.do is in fact "root-slash-processTrivia" - but in 
  relation to your current context. If your webapp is named sports, then it will 
  have to be /sports/processTrivia.do
   
  How 
  you get around this depends on your servlet container. In Tomcat 4, you could 
  make sports the default webapp, so /processTrivia.do would go to the sports 
  webapp. Other containers probably have a similar method. However, I don't 
  recommend any of these, especially if you have multiple web 
  applications.

  I'm 
  talking about webapps from the perspective of the servlet specification. I 
  don't think it's the same thing. (Think WAR files, WEB-INF 
  subdirectories)
  Some 
  servlet containers don't support/require this structure so you may not be 
  using them (eg older WebLogic).
   
  What 
  container/servlet spec. are you using?
   
  Cheers,
  Brett

here is the ONLY setting I made in 
weblogic.properties:
weblogic.httpd.defaultWebApp=D:/myapp
 
Everything else came preinstalled that 
way

  If 
  you got more sp10 to work, more power to you. It leaks about 1gb of RAM an 
  hour for me :)
   
  Have 
  you got something like this?
   
  weblogic.httpd.webApp.strutsexample=c:/jakarta-struts/webapps/struts-example.war 
  
   
  
  Or 
  are you just using a servletclasses/ type set up?
   
  If 
  you are using the first, my first instructions still hold. If you are doing a 
  lot of servlet configurations in weblogic.properties, then I'm not sure 
  because that will completely change the way it works. I haven't used struts 
  with that older method before.

  Brett
