hi all-
I am using try/catch around a cfquery, and when I use #cfcatch.SQl# within cfcatch, I get an error saying sql is undefined
in cfcatch. The same happens with #cfcatch.where#. Everything is fine with #cfcatch.detail#, #cfcatch.message#.
I have been working with #cfcatch.sql# and #cfcatch.where# with no issues until today. Can any one let me know what could be
the issueIs it a DB exception being throw? I can't say I've ever used either of cfcatch.sql or cfcatch.where (didn't even know they existed until now, so cheers for mentioning them!), but by my reading of the docs, those values are only available with DB exceptions. So if you simply have a logic error which causes an exception in your code, be it within <cfquery> tags or not, they you'll not get those values available. But like I said, this is speculation based on my reading of the docs, not any actual exposure to the situation.

Catching java.lang.NullPointerException with cftry/cfcatch?
I'm getting a java.lang.NullPointerException returned on an
update function in a CFC:
"The cause of this output exception was that:
java.lang.NullPointerException."
I want to find where it's generating this error so I can fix
it. I've never really used CFTRY and CFCATCH, but figured now would
be a good time to learn if this helped me track down the null. Can
anyone provide an example of how to use these tags with the above
NPE and output a message that give info on where it's faulting?
I'm using a standard update query,
<cfquery>
UPDATE table
SET columns = new values
WHERE ID column = some ID
</cfquery>That was a great tip Dan. Helped me find the line. Apparently
a datatype "date" was given an incorrect null value. I figured the
problem and the update works now :)
Here's code incase someone wants to know: -
Problem with return a ColdFusion query object from a Java class
Hi!
I need to return a ColdFusion query object from a Java class
using a JDBC result set ( java.sql.ResultSet);
I have tried to pass my JDBC result set in to the constructor
of the coldfusion.sql.QueryTable class with this code:
ColdFusion code
<cfset pra = createObject("java","QueryUtil").init()>
<cfset newQuery = CreateObject("java",
"coldfusion.sql.QueryTable")>
<cfset newQuery.init( pra.getColdFusionQuery () ) >
My java class execute a query to db and return QueryTable
Java code (QueryUtil.java)
import coldfusion.sql.QueryTable; // (CFusion.jar for class
QueryTable)
import com.allaire.cfx //(cfx.jar for class Query used from
QueryTable)
public class QueryUtil
public static coldfusion.sql.QueryTable
getColdFusionQuery(java.sql.ResultSet rs)
return new coldfusion.sql.QueryTable(rs);
but when i run cfm page and coldfusion server tries to
execute : "<cfset pra =
createObject("java","QueryUtil").init()>" this error appears:
Object Instantiation Exception.
An exception occurred when instantiating a java object. The
cause of this exception was that: coldfusion/sql/QueryTable.
If i try to execute QueryUtil.java with Eclipse all it works.
Also I have tried to return java.sql.ResultSet directly to
coldfusion.sql.QueryTable.init () with failure.
Do you know some other solution?ok
i print all my code

Flex Multi-File Upload Server Side File Handler
This file is where the upload action from the Flex Multi-File Upload UI points.
This is the handler the server side half of the upload process.
--->
<cftry>
<!---
Because flash uploads all files with a binary mime type ("application/ocet-stream") we cannot set cffile to accept specfic mime types.
The workaround is to check the file type after it arrives on the server and if it is non desireable delete it.
--->
<cffile action="upload"
filefield="filedata"
destination="#ExpandPath('\')#MultiFileUpload\uploadedfiles\"
nameconflict="makeunique"
accept="application/octet-stream"/>
<!--- Begin checking the file extension of uploaded files --->
<cfset acceptedFileExtensions = "jpg,jpeg,gif,png,pdf,flv,txt,doc,rtf"/>
<cfset filecheck = listFindNoCase(acceptedFileExtensions,File.ServerFileExt)/>
<!---
If the variable filecheck equals false delete the uploaded file immediatley as it does not match the desired file types
--->
<cfif filecheck eq false>
<cffile action="delete" file="#ExpandPath('\')#MultiFileUpload\uploadedfiles\#File.ServerFile#"/>
</cfif>
<!---
Should any error occur output a pdf with all the details.
It is difficult to debug an error from this file because no debug information is
diplayed on page as its called from within the Flash UI. If your files are not uploading check
to see if an errordebug.pdf has been generated.

1) I use no accept attribute. Coldfusion is then free to upload any extenstion.
Restricting the type to application/octet-stream may generate errors. Also, it is unnecessary, because we perform a type check anyway.

Server side validation for file type with cffil sent via cfmail problem
Hello;
I have a small app that I need to allow users to be able to use a form, and send me and email with a file attachment. I have it working nicely, I included file manipulation into the validation process of the form and required form fields. The problem I'm having, is this. I'm trying to create and instance where if they try and upload lets say a pdf, it throws and error: "You are trying to upload the wrong file, please try again we only accept bla bla bla" Problem is, even if I'm uploading the proper file, it's rejecting it and deleting it. Can someone help me fix this? I've tried a number of different ways and can't seem to get this to go off properly. I am posting some of the code. There is a ton, so I'm posting the main parts so you get the idea and see my variables.
<!--- Declairing my variables and setting up form validation--->
<cfparam name="FORM.descript" type="string" default=""/>
<cfparam name="FORM.attachment_1" type="string" default=""/>
<cfset arrErrors = ArrayNew( 1 ) />
<cfset showForm = true>
<cfif structKeyExists(form, "sendcomments")>
<cfif NOT len(trim(FORM.name))>
<cfset ArrayAppend(arrErrors,"Your Full Name!<br>") />
</cfif>
<!--- This is where the file error control is as you can see how the name is validated, the file will be dealt with in a similar maner--->
<cfif NOT Len(Trim(FORM.attachment_1))>
<cfset ArrayAppend(arrErrors,"You didn't attach a file!<br>") />
<cfelseif ArrayLen( arrErrors )>
<cftry>
<cffile action="DELETE" file="#FORM.resume#"/>
<cfcatch>
<!--- File delete error. --->
</cfcatch>
</cftry>
<cfelse>
<!--- no errors with the file upload so lets upload it--->
<cftry>
<cfset request.AcceptImage="image/gif,image/jpg,image/jpeg,image/pjpeg,image/x-png">
<cffile action="upload"
filefield="attachment_1"
accept="#request.AcceptImage#"
destination="c:\websites\187914Kg3\uploads\"
nameconflict="Makeunique">
<!---
Now that we have the file uploaded, let's
check the file extension. I find this to be
better than checking the MIME type as that
can be inaccurate (so can this, but at least
it doesn't throw a ColdFusion error).
--->
<cfif NOT ListFindNoCase("request.AcceptImage",CFFILE.ServerFileExt)>
<cfset ArrayAppend(arrErrors,"Only JPEG, GIF, and PNG file formats are accepted!<br>") />
<!---
Since this was not an acceptable file,
let's delete the one that was uploaded.
--->
<cftry>
<cffile action="DELETE" file="#CFFILE.ServerDirectory#\#CFFILE.ServerFile#"/>
<cfcatch>
<!--- File Delete Error. --->
</cfcatch>
</cftry>
</cfif>
<!--- This is the code that is causing my problem. The above code is saying everything is not the proper file and rejecting it all--->
Can anyone help me out. I can make more of this code available if needed. Like i said, there's a lot and I didn't want to dump it all out, this is the section creating the problem. There are no errors at this time, just rejecting all file types.

Simple file loader with cffile
Hello;
I'm trying to make a basic file loader for my web site. I've written the file upload, and it works. I'll attach that code. I was wondering if someone could help me over this small hurdle I need to get past... let me explain.
I have an admin section in my web site. This file loader is to add new thumbnail images to a db record and show it on the front end. There is an option to either edit and existing record, or add a new record.
When you get to the editor, I'm putting in a link for a pop up window that has this file loader in it. What I want to do it after you load this file, I need it to be able to close the window and add it to the editor section so the file name can be loaded into the database.
Is this possible and kind of simple? I realize nothing is too simple doing this kind of programming, I'm just trying to find a decent solution that works. Maybe there is a tutorial out there for this kind of thing? Or maybe someone can help me with a couple lines of code so I can take it from there?
This is my file loader:
<cfset UploadFolder="c:\Inetpub\wwwroot\website\img\babies">
<cfif IsDefined("Form.UploadFile") AND Form.UploadFile NEQ "">
<cffile
action="upload"
filefield="UploadFile"
destination="#UploadFolder#"
nameconflict="overwrite"
>
File uploaded successfully!
<br />
Uploaded file: <cfoutput>#cffile.ClientFile#</cfoutput>
<cfelse>
Select a file first!
</cfif>
<form name="UploadForm" method="post" enctype="multipart/form-data" action="">
<input type="file" name="UploadFile">
<input type="submit" name="submit" value="Upload"/>
</form>
I can also post the db code for the page I'm loading it into if need be. I would have to refresh the page I believe to get the info from the pop up to the parent window that spawned it. I have a script for that:
<a href="javascript:opener.top.location=('/test/edit-record.cfm');" onclick= "javascript:window.close();">close window</a>
can anyone help me make this work properly? OR point me in a direction of a tutorial for a simple file loader of this type?
thank you.I was wondering if Ajax would be a good solution. Can you tell me this
? I have a file loader I use all the time, but on this server, it's not working properly. Can you look at my code and possibly tell me why? I
know this is a lot of code I'm pasting, but it is pretty strait forward. It doesn't thrown an error, it just doesn't load the file
at all.
I would rather use this, I have it all written:
<!--- form submitted --->
<!--- set file uploading vars --->
<cfparam name="fileuploaded" type="boolean" default="false">
<cfparam name="uploadedfile" default="">
<cfset pathToFile = "c:\Inetpub\wwwroot\website\img\babies">

Moving to CF10, Need help with Application.cfc
I've been googling about how to work with Application.cfc since last week but I still have some questions and I can't find the answers.
My application is under the root (in unix) and there are many subfolders underneath it. Each sub-folder is hosting a different web application.
From what I read, I can create 1 root Application.cfc and then on subsequent sub-folder, when I need to have another Application.cfc on that level, I can create ProxyApplication (see below) and then create a sub-folder level Applicatin.cfc
So, when I set an application.DSN on my root Application.cfc, using proxyApplication I don't have to reset this dsn again in my sub folder level Application.cfc
Since my loginform.cfm and loginaction.cfm is right under root directory too, I also set OnsessionStart in the root Application.cfc to handle user login. Then this means, I don't have to reset session variable again anywhere because session.username, etc has been set on the highest level.
Is this correct?
In addition, Am I correct when I do the following:
1. Since I have root level and sub-folder level Application.cfc, I should set this.name with a different name, am I right?
On the root Application.cfc I set this.name = "StudentServices" because this represent the global application
On the sub-folder level's Application.cfc, I set this.name to "StudentServices_stdLoad" becaus this sub-folder only handle student load application.
2. On the root Application.cfc, I set the DSN to the application scope. So on the sub-folder level Application.cfc I can check if a particular db is working or not
because as awhole, in the global sense, this web application uses more than one Databases. Each sub-folder may use a database that is dfferent than the other sub folder.
Am I doing the right thing? Please advice
Below is example of what I have, Thank you!
I created a root Application.cfc under the root directory:
<CFCOMPONENT displayname="Application" output="true" hint="My Root Application component">
<!--- Set up the application ---> <cfset THIS.Name = "StudentServices" /> <cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,30,0) /> <cfset THIS.SessionManagement = true /> <cfset THIS.SetClientCookies = false />
<cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false">
<cfset application.MainDSN = "DSN1">
<cfset application.ReportDSN = "DSN2">
<cfreturn true/>
</cffunction>
<cffunction name="onApplicationEnd" output="false">
<cfargument name="applicationScope" required="true"> </cffunction>
<cffunction name="onSessionEnd">
</CFCOMPONENT>
Then, in this root directory I also created a ProxyApplication:
<!--- it's empty and it Serves merely to create an alias for your root /Application.cfc --->
<cfcomponent name="ApplicationProxy" extends="AdvancementServices.Application">
</cfcomponent>
Then in the Sub-Directory, I can create a sub-folder level Application.cfc extending the root Application.cfc:
<CFCOMPONENT displayname="Application" extends="ApplicationProxy">
<!--- Set up the sub-folder application --->
<cfset THIS.Name = "StudentServices_stdLoad"/>
<cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,30,0) />
<cfset THIS.SessionManagement = true/>
<cfset THIS.SetClientCookies = false/>
<cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false">
<!--- ****** Testing whether the ADVUPGRD is accessible by selecting some data.****** --->
<cftry>
<cfquery name="TestMain_DSN" datasource="#application.MainDSN#" maxrows="2">
SELECT Count(*) FROM MyTable
</cfquery>
<!--- If we get a database error, report an error to the user, log the error information, and do not start the application. --->
<cfcatch type="database">
<cflog file="#this.name#" type="error" text="Main DSN is not available. message: #cfcatch.message# Detail: #cfcatch.detail# Native Error: #cfcatch.NativeErrorCode#" >
<cfthrow message="This application encountered an error when connecting to the Main Database. Please contact support." />
<cfreturn false>
</cfcatch>
</cftry>
<cflog file="#this.name#" type="Information" text="Application #this.name# Started">
<cfreturn true/>
</cffunction>
</CFCOMPONENT>
<cfargument name = "SessionScope" required=true/> <cfargument name = "AppScope" required=true/>
</cffunction>
<cffunction name="OnSessionStart" access="public" returntype="void" output="false">
<CFSET session.UserGroup = ""/>
<CFSET session.UserName = ""/>
<CFSET session.currentPage = ""/>
<CFSET session.loggedin = "No"/>
<CFSET session.userrights = ""/>
<cfreturn/>
</cffunction>OK. It sounds to me like you really shouldn't be using a single root Application.cfc at all, if all you want to do is share some settings between your "sub-applications". I would look at storing the common settings in an external file that all of the applications can read in. The simplest way is to put the settings in a .CFM file somwhere outside of the web root (so it is not directly web accessible) and load it with <cfinclude> tag into the OnApplicationStart() method of each sub-application's App.cfc. That .CFM file can be as simple as:
<cfset application.myCustomSetting = "blahblah">
<cfset application.myOtherSetting = "foo">
Alternatively, you can look at using a config file like this Ray Camden blog post suggests, and use the GetProfileSection(), GetProfileString(), and SetProfileString() functions as needed within OnApplicationStart(). You could even put ALL of your settings in
A third option is to store your settings in an XML file or in JSON format in a text file. You could then write code to read in the XML file, and use something like xml2struct.cfc to convert the XML into a struct, then append the struct to your application scope. If you go the JSON route, then just read in the JSON file and use DeserializeJSON() to convert it into a struct, and append it to the application scope.
What I think is probably the best approach is to use a community-supported MVC framework like FW/1 or ColdBox (maybe you already are, I don't think you've said so though). One of the many advantages to doing so is that they have built-in "environment" support that can be used to configure common settings, depending on your environment (dev/qa/production). You would handle reading in your external settings through the "environment" mechanism.
One other thing to think about: your login mechanism. I think you want to use one set of login tools that is shared by all of the "sub-applications". You can do this also by putting the login/authentication-related code somewhere outside the webroot of your applications, and then either set up a mapping to that location in CF Admin, or set an application-specific mapping in your various App.cfc files. That way all the "sub-applications" share a common set of code for the login process. I don't know how your login process works (do all users go to the same login page then get redirected into their relevant "sub-application", or does each "sub-application" have a discrete login page that utilizes common back-end processes to authenticate and redirect), so you'll have to judge how that is best accomplished.
Hopefully this gives you some useful ideas.

Hi,
How can I read xml file using web services?
Here is my cfc web services: (I just want to see how to read the xml file)

Hello, does anyone have a suggestion on handling errors from
CFFEED reads?
I'm reading an ATOM RSS feed from another site, but if there
is ever an issue with that remote site, it would prevent my page
from loading.
If, for example, the RSS feed wasn't available, I would get
an "Unable to read the source URL" error page.
What I would like to have happen would be the page to
continue processing, and instead of displaying the <CFOUTPUT
query = "myQuery">, instead display something like "There was a
problem with the newsfeed".
Is there any way to ignore a "fatal error" from a CF tag, and
just move on with processing the rest of the page?
The code I've used here is Adobe's example for the CFFEED
tag. The RSS URL I'm testing with is:
http://feeds.emsresponder.com/emsresponderrss/top_ems_news
Thanks in advance!
-Ian in Los AngelesUse CFTRY and CFCATCH as suggested above. These tags can be
used around pretty much any potentially problematic code.
A good idea might be to put a CFMAIL tag in the CFCATCH which
will notify you if something is wrong - although, this depends on
how many people you'll have viewing the page, because you could end
up getting a lot of emails - I'm sure there must be a better
solution somewhere though, just an idea really. -
MM_XSLTransform.cfc error: cfcatch.Proc
I've been using the MM_XSLTransform.cfc for a couple years to
do XSL transformation on a site, and it's worked quite well. Only
just last night, I started receiving an error regarding
cfctach.Proc:
Element PROC is undefined in CFCATCH. <br>The error
occurred on line 135.
As well as:
Element PROC is undefined in CFCATCH. <br>The error
occurred on line 133.
The version of the CFC that I'm using is 0.6.2, which I
believe is the version that comes with Dreamweaver 8. Not sure if
there's a new version for Dreamweaver CS3 or Dreamweaver CS4, for
that matter.
In any case, the lines in question are as follows:
<cftry>
<cfset XMLParse(myFile)>
<cfcatch type="any">
<cfif type EQ "xml">
<cfset setError(getErrorFromCode('MM_INVALID_XML_ERROR',
errSrc) & cfcatch.Proc & ' ' & mySrc & '<br>'
& cfcatch.Message & '<br>' &
HTMLEditFormat(cfcatch.Detail) & '<br>' &
HTMLCodeFormat(myFile))>
<cfelse>
<cfset setError(getErrorFromCode('MM_INVALID_XSL_ERROR',
errSrc) & cfcatch.Proc & ' ' & mySrc & '<br>'
& cfcatch.Message & '<br>' &
HTMLEditFormat(cfcatch.Detail) & '<br>' &
HTMLCodeFormat(myFile))>
</cfif>
</cfcatch>
</cftry>
This error could also potentially pop up in this section:
<cftry>
<cfset output = XmlTransform(Arguments['xml'],
Arguments['xsl'])>
<cfcatch type="any">
<cfset
setError(getErrorFromCode('MM_TRANSFORMATION_ERROR') &
cfcatch.Proc & & '<br>' & cfcatch.Message)>
</cfcatch>
</cftry>
In looking at the documentation for cfcatch, Proc (as in
cfcatch.Proc) does not appear to be a valid attribute for cfcatch,
and there isn't anywhere else within the cfc where Proc gets tacked
on to the cfcatch.
For now, to prevent the error from occurring, I've commented
out all instances of cfcatch.Proc.
Not sure why this popped up now. It may mean there's an error
in one of my XML files, which I will need to investigate.
If anyone has any insight to share on the perils of
cfcatch.Proc, it would be appreciated.
Thanks,
MarcI am passing RequestTimeOut="120" in the url. The 120 seconds
is the value that has been determined to be the maximum that we
want the app to run before timing out. The issue I have is that the
ColdFusion Blue Error page is not acceptable error handling and I
have not been able to capture the timeout. That is my request, how
to capture the timeout and follow acceptable error handling in this
timeout situation. -
Coldfusion Error catching (cftry cfcatch) best practice question...
Hey all -
I wanted to get a couple of opinions about this. Obviously I want to catch any and all errors that hit my server and avoid exposures to my end users, but I didnt know what the most efficient way of doing such was. Does it make sense to put a cftry cfcatch around the entirety of my code on every page? (I use a lot of embeds...cfinclude) Or is that too broad? How does that effect performance? Is there another way to auto catch and email all errors and then show the user a custom error page? I searched around, but I got bits and pieces based on specific requests...not really any "best practice" tips. Any suggestions would be fantastic.
Thanks much!There are no real best practices as such, as it's largely down to your application. The only real "standard" is the onError() method in Application.cfc, which will handle any Exceptions which make their way to it - i.e. any that are not caught by an explicit try/catch block.
When considering what you are now, I consider this: where do I want to display an error? How far down the line does it matter? There's no right or wrong answer, it's down to you.
Say you're displaying a page, which is made up of ten includes. If there's an error in one, do you want the other nine displayed, or do you want the whole page to error? If it's the former, wrap each one in its own try/catch. If it's nonsensical to do so, just let the page throw an Exception to get picked up by your Application.onError() method.
It also depends largely on whether or not an error is "recoverable" - is it of any use telling someone that a small but important part of the page failed becuase of a database issue? Probably not. There's nothing they can do about it, so just throw an error and let your error template sort it out.
It also depends on the context in which the page is being called - if it's an Application with users, you can display an error page with as much or as little information as you want. If it's a remote CFC call, however, it's extremely annoying for the remote developer to just get useless ColdFusion exceptions. Therefore I would always wrap every remote CFC method in its own try/catch, so if something goes wrong you can still return them something useful - even a "false" is better sometimes than an exception. You can then do what you like within the catch block - send you an email, log to disk, whatever.
Just a few thoughts, haven't proof read them though so expect massive, glaring mistakes and poor advice. -
I got a system that is behaving strange what appears to be randomly.
I create a CURD cfc for this table and to store the password I use
Encrypt and when it's been red from the CFC it gets decrypt by the cfc.
Here is the few lines of code from the CFC that is in charge of it.
On update (same method is doen on crate as well):
<cfif isdefined("arguments.fu_password")>fu_password=<CFQUERYPARAM value="#left(encrypt(trim(arguments.fu_password), this.encKey),250)#" cfsqltype="cf_sql_varchar" maxlength="250">,</cfif>
On read (after I query the database):
<cfloop query="qReadFrontend_Users">
<cfset qReadFrontend_Users.fu_password[currentrow] = #Decrypt(qReadFrontend_Users.fu_password[currentrow], this.encKey)#>
</cfloop>
It worked well (I use this method everywhere I need to save the data encrypted) for a long time, and IT STILL works well on my server. But about 2 months a go I started to get errors that the input/output of the encryption is not the same.
The MUST strange thing is that the errors will be sent to me WITOUT the page being viewed been relocated to the error page (which is what happens when an error accurse on that system). And on top of that the CFC would RETURN the SQL with the RIGTH INFO !! IE it decrypts the info but yet say there was a problem.
I then added this to the CFC …
<cftry> <!--- THIS IS A TEST --->
<cfloop query="qReadFrontend_Users">
<cfset qReadFrontend_Users.fu_password[currentrow] = #Decrypt(qReadFrontend_Users.fu_password[currentrow], this.encKey)#>
</cfloop>
<cfcatch type="any">
<cfmail from="****" to="*****" subject="FRONT END USERS CFC CF CATCH EMAIL !!!!" type="html">
cfcatch:
<cfdump var="#cfcatch#">
<BR><BR>
arguments:
<cfdump var="#arguments#">
<BR><BR>
Query
<cfdump var="#qReadFrontend_Users#">
<BR><BR>
this
<cfdump var="#this#">
<BR><BR>
cgi
<cfdump var="#cgi#">
</cfmail>
<cfreturn qReadFrontend_Users>
</cfcatch>
</cftry>
And I started getting emails. in all of the emails the RETRURNED query is fine, as I mentioned above.
I also checked the DB, outputting each row and its decrypt password, the problems is not in the DATA IT SELF, the data is k-ok !.
And again this happens totally on random, no pattern to it what so ever.
My Q' is, did any one encountered something like this?
My first guess was that the SQL is not ok in some why, but I have NO idea what to look for.
Please HELP : )Sorry, I have solved this problem, Thank you.
