RE: Problem with using variables scope

[Michael Nguyen]

I would upgrade CF to 7 or 8 it but it's client's decision, unfortunately:(
I have fixed that by changing variables scope to "this" scope. It works but
you know about the disadvantages of using this.instance rather than
variables.instance. It's just a fix to get it works but I'm not quite happy
and can't explain why variables.instance is visible from outside.

Never seen that with 7 and now 8 and do that type of thing all the time.

If this is just 6, id say upgrade. Your right, it shouldn't happen.

Subject: Problem with using variables scope

Hi People,
I have encountered a very weird error with variables scope. 


and 


Then I dump those two objects and found that the AnnouncementBean object is
the same as
AnnouncementType (it has properties and methods of AnnouncementType )
When I comment the creation of the second object then dump it, it show the
correct object.

I found that because 
 is declared in both objects
and when I created the second object, this  variables.instance overrides the
first
variables.instance was created in the first one.

To me, it's really really weird as the variables scope exists only within
that object.

Using CFMX 7 is ok, the CF6 causes this problem. I am running in Unix.

Any help is appreciated.

RE: Web service error, pls help

[Michael Nguyen]

Hi Neil,

I re-write here what problem I have:

I use wsdl2java in JRun to get stubs and wrote a java wrapper class to talk
to those stubs (same as article Creating webservice stubs with wsdl2java in
ColdFusion MX 7
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=eaf0396)

I've got 500 NULL with page title is JRun Servlet Error

When I go to the log exception log, I see the following exceptions:

1) This is when I restart ColdFusion and try it the very first time:

Error","jrpp-0","11/28/06","15:13:42",," The specific sequence of files
included or processed is: C:\Inetpub\wwwroot\transtar2\cfm\Test.cfm "

java.lang.ExceptionInInitializerError
  at org.apache.axis.client.Service.getAxisClient(Service.java:143)
  at org.apache.axis.client.Service.(Service.java:152)
// more lines..

2) And this is what I get any time there after:

"Error","jrpp-0","11/28/06","15:16:22",," The specific sequence of files
included or processed is: C:\Inetpub\wwwroot\transtar2\cfm\Test.cfm "
java.lang.NoClassDefFoundError
  at org.apache.axis.client.Service.getAxisClient(Service.java:143)
  at org.apache.axis.client.Service.(Service.java:152)
  at ..

// and more lines.

The ws that I try to consume is:
http://www.tracking.edi.com.au/webservice/shipmentservice.asmx?wsdl

If you need, I can send you a pdf about this ws.

Please, let me know if you want to know anything more...
Thank you very much

Michael Nguyen

Hi Michael,
I recently ran into what I believe is the same problem that you are. The
problem is that CF is weakly-typed, and the WSDL is describing complex data
types that CF cannot figure out what to do with. The bottom line is that CF
*can't* consume that web service using CFML, you must do it using Java (or
...NET if on BD.NET).

Rob Munn (giving credit where it's very much due) answered the same question
for me as so (check out the CFDJ link, the article shows how to get around
the problem):

CF isn't good at invoking complex web services. The best way to deal with
this problem is to use WSDL2Java to create the Java libraries to invoke the
web service, then write a wrapper class in Java to use them. You can then
call the Java wrapper class from CF. There is a learning curve the first
time you tackle it, but after that it gets easier. I wrote an article on it
that you can find here:

http://cfdj.sys-con.com/read/86131.htm


The key is making sure you build the libraries and your wrapper class with
the same versions of the Java Axis classes that CFMX uses.
Rob

So there you go, probably not the news you were looking for though. Hope
that helps!

I've got an weird error message when trying to consume webservice:

There was a demonstration utility that consumes this webservice written in cs 
working fine with this ws.

Could anyone give me an idea what the problem is?

RE: Using CFHTTP to login

[Michael Nguyen]

Yep, I see your point, you reminded me about it before. In the .Net, the
login.aspx is the login form as well as login action as it submits to
itself. The reason why I did not explain it that clearly as I didn't think
it matter (?) and we have a lot messages just discussed on what is what and 
Sorry if it make some different ;)

Now wait a minute. The CF FORM works, but then the ACTION requested by 
CFHTTP doesn't right?
But the CF form doesn't have the session cookie set by the .NET form, 
and then cannot transmit it to
the action. This could be enough to make the login fails.

So, if I were you, I'd try this :
1. CFHTTP the .NET FORM first,
2. get the session cookie,
3. CFHTTP the ACTION with this session cookie.

You already tried something similar:


http://www.mycompany.com/Login.aspx"; method="get"
resolveurl="yes" port="80" throwonerror="yes" redirect="yes"
useragent Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.7)
Gecko/20060909 Firefox/1.5.0.7"/>


.


but here you call the action page, you should call the FORM page to get 
the correct
session cookie, not the action page.

1. Delete all cookies
2. Go to login form in .Net.
3. View cookie: There is a cookie ASP.NET_SessionId=4mnaix453yw12h55ox3myn45

Ah ah! This is their session Id. Now if they keep a session live, they 
may also have some
data stored in it, and if that session is not found by the action 
template, this may be
why the login does not work.
Then you have to make sure your CF script will CFHTTP the form first to 
get that session cookie,
then pass it when you CFHTTP the action for the login.

 >>4. DELETE that cookie
 >>5. Click Submit

So you deleted the cookie before calling the login action? Then did the 
login succeed?
If it did, it does not prove the cookie is not needed, I'm not sure that 
deleting a cookie or all
cookies wil delete the ones already in memory.

RE: Using CFHTTP to login

[Michael Nguyen]

>> No, you must check with the original login form on the .NET application.

Here is how I check with the original login form on the .Net app.

1. Delete all cookies
2. Go to login form in .Net.
3. View cookie: There is a cookie ASP.NET_SessionId=4mnaix453yw12h55ox3myn45
4. DELETE that cookie
5. Click Submit
6. View Cookie: Two cookies: ASP.NET_SessionId=n4dg3azlmh4ga1mm2wnmmq55
(note: different value) and .ASPXAUTH=314508822A3EDF0...
7. Log off then view cookie: There is only
ASP.NET_SessionId=n4dg3azlmh4ga1mm2wnmmq55 but .ASPXAUTH=314508822A3EDF0...
does not exist.

I thought that this is the key but I don't have the answer. :(
I am 100% sure but I think that the thing which you asked me to disable
cookie and try to login using login form is a very important which gave us
the reason why login with cfhttp failed.

>> You told me that the login fails when cookies are disabled, but what if

The login action is working well with JS disabled and cookie is enabled.

I would be more than happy to give you one when I get a new testing account.
Probably not soon as it's public holidays now in Australia :(

Anyway, I really appreciate your time and help so far

No, you must check with the original login form on the .NET application.
The CF template you've made does not set any cookie (except the one set 
by CF).
The idea is the check if the ORIGINAL login form in the .NET application
sets a cookie, because this is the one you must fake when you simulate 
the login form by CFHTTP.

The thing that is weird is that, with cookies disabled, the login action 
will fail.
The question then is how does the login action know that cookies are 
disabled?

The only way I have in mind is that the action will verify the presence 
of a cookie
set by the form.

There is also a Javascript property "cookieEnabled" that the system can 
also check.

You told me that the login fails when cookies are disabled, but what if 
they are enabled,
but Javascript is disabled ?

Finally, is there an address (and some code + password) I could use to 
test the real application
by myself?

RE: Using CFHTTP to login

[Michael Nguyen]

Thx Claude, here is what I have been trying

1- Delete all Fire fox cookies
2- Go to http://localhost/SingleLogin/login.cfm (which is the login form)
3- View Cookies: There is a cookie has been written by CF with CFID,
CFTOKEN, JSESSIONID. Note: No cookie from ASP.net
4- Click Submit Result: Is redirected to member home page: successful
5- View cookie: There are cookies .ASPXAUTH=59EDCFD5BF... and
ASP.NET_SessionId=yynrg545cibzz4554zrsfh45
6- Logout
7- View cookie: There is only ASP.NET_SessionId=yynrg545cibzz4554zrsfh45,
the .ASPXAUTH has been expired and doesn't exist.

Is there anything you think of?

 >>Yes, but you are doing it from your browser.

Another try:
When you call the login action from your CF login form, the request is 
actually sent by your browser.
Then, if may have some cookie in it set previously by the server, it 
will recognize it and the
login is accepted.
When calling from CFHTTP, you don't have these cookies, and the login fails.

Now, can you try again your CF login form just after having erased all 
your cookies.
If some check cookie was set initially by the normal login form, your CF 
form should fail now.

Then you know what you have to look for.

RE: Using CFHTTP to login

[Michael Nguyen]

I don't think so Claude. The reason is the html form (login1.cfm) is working
well and I try to simulate the login process exactly as we login as that
html form.

>> One thing I'd like to know: what is the feedback you are getting from

>> I mean from your CFHTTP. Any message about the reason it failed?

The login process happens like this: If the login is successful then it
redirects to another page like member home page. If not, it redirects user
to login form with an error message: Login failed!

When using login1.cfm (which is working) then after submitting, the member
home page is shown. If I type in incorrect details then it redirects to
login form say login.aspx with message Login Failed.

When using CFHTTP and dump cfhttp.filecontent, the login form login.aspx is
shown WITHOUT any error message just like you get there first time. Claude,
remember you asked me to try to disable cookie and submit the form that
works? I got the same screen as I do with cfhttp which is login form WITHOUT
any error message. I would suggest that the problem might be is the asp.net
think that the cookie is disabled and the login process does not happen. It
simply redirects user to the login page.

I have been pulling out my hair but no luck so far...

Thx

RE: Using CFHTTP to login

Hi all,

One thing that I've noticed and think that it may be or may not be related
to the problem:

After normal successful logged in into asp.net using html form, the cookie
has one more name-value:
..ASPXAUTH=9857AD003ACCC01 which we didn't have before logged in.

RE: Using CFHTTP to login

[Michael Nguyen]

Thanks Claude, you always pointed out the very good point. I very
appreciated your messages and suggestion.

I've made a little bit of change to make sure that the cookie I got is
correct from the form page but no luck.

One thing I would like to mention here is the html form that works (says
login1.cfm) hasn't got any cookie info from asp.net app yet because this
form lies on CF server. It likes the user go to cf login1.cfm (note: this is
a login1.cfm locates in CF application and it has got any info of asp.net
before hand) and submit login details to asp.net and the results is asp.net
redirects user to the member home page in asp.net application. 

I make another login2.cfm which will submit to itself. In that CF will log
the user in CF app (that's no problem) and also makes a http request to
asp.net(using cfhttp) to also log user into asp.net application.

The thing is the login1.cfm has got any info from asp.net yet but it does
its work, however the login2.cfm can get logged in into asp.net.

Sorry if something is unclear. Please let me know if anything you might
think of.

Thanks a lot

Yeah, but as I told you, unless the code you copied on your message is 
not correct,
you should get the cookies from the form page, not the action page.

Yeah... I would think that if I dump cfhttp.filecontent I expect to see a
member login page in successful case.

The thing is the html form I've made does the same thing as cfhttp does, but
one can get through and one cannot. For the next request I should pass
cookie info (in every subsequent request) but it is my second step. My first
step is to see asp member home page when using cfhttp.

Michael, 

I know you've received lots of suggestions already, but I want to backup a
little bit and try to unerstand what you're trying to do. I've read the
thread history and I think there is perhaps a misunderstanding somewhere.

What I understand is that you have an aspx page that you can log into by
making a direct http call from the client browser, to the aspx page.

What I also understand that you are trying to do, is have a cfm page that
makes a similar aspx call (via CFHTTP) to log in the client. 

The challenge in this is that any settings passed back from the aspx page
will be sent to the ColdFusion server. They will NOT be passed back to the
client browser from the CF server. Even though they are sent to the
ColdFusion server, the server will not "remember" the response on a
subsequent request.

Hopefully that makes sense. Please feel free to clarify if I have
misunderstood the intended functionality.

Jason Troy

Michael,

You are going to have to "get" the cookie scope from your browser and send
it along with the page.

1) Create an ASPX page that loops through the cookie scope and sets
Javascript variables.
2) Embed the ASPX page as a Javascript on your CF page ()
3)  copy the JS variables into the form scope using javascript and post them
to your CF handler 
4) Send them back as cookies in your CFHTTP post...

It's also possible that simply embedding the js/aspx into the CF page will
set the appropriate cookies and you won't need any JS... They will exist as
cookies in your CF cookie scope and your  code below would work. I'm going
to bet that would work differently in different browsers though.

Claude, if I disable cookie then I couldn't login form the login form that
works if cookie enabled. I think that was the point.

When I submit the form (that works) if cookie turned off then it show me
exactly as when I cfhttp.
How can we get around of it?
What I have tried is do cfhttp twice. The first cfhttp is to get cookie from

(see the code bellow). However, I haven't got it done yet.

Javascript for instance. (My own login procedure on my systems work this

Try your login form that works (and which is NOT the same as the login

with Javascript disabled and see if you can still login.
Try also with cookie deactivated and see if it makes any difference.

When I dump cfhttp.filecontent it shows me the login page (which is not

Using cfhttp to login

[Michael Nguyen]

Hi everyone,

I am still struggling with using cfhttp to log in into an ASP.NET app.

The weird thing is when I used the normal html form (see bellow) then I could 
log in successfully:

http://www.mycompany.com/Login.aspx";  name="form1">

  

  
  
   

However, when I use cfhttp (bellow) to login then I could not log in:

 

http://www.mycompany.com/Login.aspx"; method="post" 
resolveurl="yes" port="80" 
 redirect="yes"
 useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.7) 
Gecko/20060909 Firefox/1.5.0.7">
  
  
  
  


Can anyone tell me how differently the asp.Net treats to these above two 
approaches and why I couldn’t login when using cfhttp?
Any help is appreciated.

Michael

Problem with using cfhttp to login to asp .net

[Michael Nguyen]

I'm having a problem with login to a asp.net. 
Firstly, I use cfhttp to make a request to the login page to get cookie info 
(ASP.NET_SessionId) Secondly, using cfhttp to login (passing ASP.NET_SessionId 
in cfhttpparam type="cookie" and my login details) Finally, I use cfhttp to 
request the index.aspx page to check whether the login is successfull but it 
seems that I couldn't log in. It return me back to the login page.
My code is:
 http://www.mycompany.com/Login.aspx"; method="get" resolveurl="yes" 
port="80" throwonerror="yes" redirect="yes"
 useragent="#cgi.HTTP_USER_AGENT#"/>




  
  cfset structInsert(cookieStruct,cookiekey,cookievalue)>
 



http://www.mycompany.com/Login.aspx"; method="post" 
resolveurl="yes" port="80" 
throwonerror="yes" redirect="yes"
useragent="#cgi.HTTP_USER_AGENT#">

   
  
  
  
   

 http://www.mycompany.com/index.aspx";
resolveurl="yes" port="80" throwonerror="yes" redirect="yes"> 
   
 

 #cfhttp.FileContent#"

I have a look in the cookie if I logged in using html page, i also see cookie 
key .ASPXAUTH and value is E94ED8F which I don't see that in the response 
header when using cfhttp.

I think that this might be a well-known problem for many people. 
Does anyone know what the problem is?
