I'm new to ColdFusion and have been experimenting with it. We migrated from Adobe ColdFusion 9 to Adobe ColdFusion 2016 and are now getting the following error.
Inside a component, I'm setting properties to define the multiple databases that I've been using. In ColdFusion 9 it works well. See the image below where the properties are set either in an empty string or a value.
ColdFusion 9
With ColdFusion 2016, the values are undefined. I don't know why is this happening.
ColdFusion 2016
So when I try to login, this error shows:
I wonder why the values are not being defined in ColdFusion 2016.
Here's a snippet on how I code my component:
component output="false" hint="Database Connection Settings" displayname="Datasource" accessors="true" persistent="true"
{
property name="Datasource";
property name="itmanagement";
property name="fixedasset";
property name="login";
property name="hris";
variables.instance = {
Datasource ="",
itmanagement="itmanagement",
fixedasset="wareakay",
login="login",
hris="employee_db"
};
}
EDIT: I think, the term "Datasource" is a reserved word now. When I change this into another word, my code goes working again.

I have created a number of datasources in Lucee using code. This is for a legacy ColdFusion application that we are migrating to Azure, and per the powers-that-be, they want the DSNs created in code so we can store the DSN passwords in a keystore. I have that part already working.
The datasources look something like this: this.datasources["myDSN"]
If, in the code (Application.cfm), I do this:
<cfset myDSN = this.datasources["myDSN"]>
This will then fail:
<cfquery name="whatever" datasource="#myDSN#">
It fails with "datasource myDSN not found."
BUT, if I do this instead:
<cfquery name="whatever" datasource="#this.datasources['myDSN']#">
... it works fine.
Is there a workaround for this? At last check in this one application alone, there are 368 occurrences of datasource= in 115 files. I'd rather not have to do a bulk search/replace. It makes no sense to me that the variable "myDSN" would fail.
As there are multiple datasources being used, I can't just set the default datasource and remove the datasource= attribute entirely; even then, it'd still require a mass search/replace.
I must be missing something. I've read the Lucee docs on datasources but it hasn't helped. Thanks!
Turns out that Scott Stroz was correct. I switched over to Application.cfc and now it works fine.
[RESOLVED]
I have a C# program which interfaces with ColdFusion by running a CFM file.
One of the tasks of the CFM file is to create three datasources in ColdFusion. This works well.
The issue I am dealing with is that I have a requirement to use the same methodology in order to delete a datasource. According to Adobe's documentation this function is available, but I cannot find any examples of this on the WWW.
Can anyone here guide me as to how to remove a ColdFusion datasource using code within a CFM file?
Thanks in advance.
Regards,
Ken.
As pointed out by Alex, I really should have included the ColdFusion version number. Version 11.
The working resolution inspired by Ageax's answer is:
<cfscript>
adminObj = createObject("component","cfide.adminapi.administrator");
adminObj.login("#URL.cfpw#");
myObj = createObject("component","cfide.adminapi.datasource");
myObj.deleteDatasource("#URL.ds#");
</cfscript>
I have posed my code here, only because this is the code I actually used and tested.
You can programmatically call the CF Admin API. I believe you can do something like this inside a ColdFusion file.
<cfscript>
/* Connect to CF Admin API */
dbConnection = CreateObject("cfide.adminapi.administrator").login("adminPW","adminUser");
if (dbConnection) {
/* Instantiate datasource object */
ds = createObject("cfide.adminapi.datasource");
/* Delete the datasource */
ds.deleteDatasource("myDatasourceName");
}
</cfscript>
Note: I don't currently have a CF server that I can test on, so please double-check me.
I am writing a ColdFusion program that uses cfquery to get data from an AS/400 iSeries table and then output that data to a web page. Some times the Data is in Chinese, but it does not output the Chinese characters correctly.
I built the query below for testing,
<cfprocessingdirective pageEncoding="UTF-8" />
<cfquery name="Test" Datasource = "AS400">
select dsc1 from sales where ref = '123456'
</cfquery>
<cfoutput>#test.dsc1#</cfoutput>
The result should be "M5方头螺栓" but I only get "M5". I did another test running just:
<cfset x = "M5方头螺栓"/>
<cfoutput>#x#</cfoutput>
and it displays the Chinese no problem.
Since ColdFusion can display the characters when they are written out in the code, but not when it goes to get the data through SQL, it seems like the issue is with either my ODBC settings or my ColdFusion Server Data Source Settings but I'm not familiar enough with these settings to know what needs to be changed to get this working.
A workaround was found and discussed within the comments. Adding some details here as an answer for future visitors to this page.
There are a couple of considerations when dealing with Unicode (Chinese) characters:
The data type for the database table must be set to nvarchar
The form processing script (CFML) must be set to utf-8
I believe ColdFusion defaults to this but you can specify the setting to be sure.For example: <cfprocessingDirective pageEncoding=”utf-8″>
Enable "String Format" within the ColdFusion datasource settings
Under the ColdFusion administrator datasource settings select the appropriate datasource you are using. Then click on the "show advanced settings" button. That will show an option for "String Format" Enable High ASCII characters and Unicode for data sources configured for non-Latin characters. Select this option and save the datasource.
The issue for the OP was that they were using an ODBC datasource and the "String Format" option was not available. After some research and the lack of finding any way to configure an ODBC datasource for that setting I recommended trying to use the builtin JDBC driver for "DB2 Universal Database" that comes with ColdFusion. Switching to that driver resolved this issue for the OP.
From the comments
Good info. Though is "Enable String Format..." necessary with the added support for cf_sql_nvarchar in CF10+? – #Leigh
I do believe Leigh is correct that the newer versions of ColdFusion (10 and later) have much better support for nvarchar fields.
Also to note, it looks like some older versions of ColdFusion don't always work with the installed DB2 Universal Driver, and it doesn't look like the older standard versions even have it, I'm not sure if the newer ones have it either, but using the "other" option with jt400.jar, should also work. - #MHall
You've already proven that CF can output UTF-8 characters correctly. Have you tried running that query in the DB console or UI? Do you get the correct charaters?
If the characters were stored as VARCHAR and not NVARCHAR, then there's nothing you can do. The data has to have been properly stored in the first place.
If the characters are stored correctly in the DB, try adding <cfprocessingdirective pageEncoding="utf-8"> at the top of the request. CF should be using UTF-8 by defualt, but this will force the correct character set if, for some reason, it isn't.
ColdFusion 10 now supports this syntax for creating a Solr collection:
cfcollection supports script style syntax:
new collection().CREATE(collection="<collection_name>", engine="solr", path="<path to the solr directory>");
Is some sort of syntax like this available in Railo 4?
I keep getting an error saying:
invalid component definition, can't find collection
If not, can this be set up as a UDF so that I can call it from a script-based component?
The latest beta of Railo 4.0 currently implements the following objects:
Feed
Ftp
Http
Mail
Query
So, the answer is no - there is no "collection" object.
(You can of course raise a feature request for adding that.)
However, there is an alternative - in Railo pretty much all the tags can be reproduced in script form.
You can write:
<cftagname attributes />
as
<cfscript>
tagname attributes ;
</cfscript>
Or for tags with bodies:
<cftagname attributes >
...
</cftagname>
becomes
<cfscript>
tagname attributes
{
...
}
</cfscript>
So simply factor your cfcollection tag in this form and it should work fine.
Pretty simple, I need to insert a script in Sitecores (v. 6.4) backend - how do I do it?
It doesn't matter if the script is placed inside <head> or <body>, nor does it matter if I can only specify the src of a <script> tag or if I can insert an actual Javascript snippet (the latter is preferable though).
The script needs to be inserted in the HTML when a Content Editor window is opened.
It is not an installation of my own, nor do I develop anything for Sitecore (I do have admin access, however), so something along the lines of installing a plugin would be the best solution I reckon.
I've previously inserted the script in Sitecore 5.4, but not in a pretty way (editing XML files) and if a better solution could be found here too, that'd be pretty great.
Update using Jens Mikkelsens answer in Sitecore Xpress 6:
I tried placing the following in web.config:
<clientscripts>
<everypage>
<script src="/test.js" language="javascript" />
</everypage>
<htmleditor>
<script src="/test.js" language="javascript" />
</htmleditor>
</clientscripts>
Being a little bit overzealous (and wanting to make sure the test.js file can be found) I put a js.test in the following locations:
inetpub\wwwroot\SitecoreWebsite\WebSite\sitecore\shell\Applications\Content Manager\
inetpub\wwwroot\SitecoreWebsite\WebSite\sitecore\shell\Applications\
inetpub\wwwroot\SitecoreWebsite\WebSite\sitecore\shell\
inetpub\wwwroot\SitecoreWebsite\WebSite\sitecore\
inetpub\wwwroot\SitecoreWebsite\WebSite\
Content of the test.js:
alert("Test [PATH TOKEN]");
Where the path token is just the parent folder name, so I know which test.js was loaded, e.g. inetpub\wwwroot\SitecoreWebsite\WebSite\sitecore\shell\Applications\Content Manager\test.js holds:
alert("Test Content Manager");
When I try to log in using the default Xpress admin user one of three things happens (in all three cases the frontend loads without errors, but no script present. I have NOT been able to determine when the errors happen, the only thing I can say for sure is that no errors occur when the test.js has not been included in web.config):
Case 1:
The content editor loads as expected, but no script is loaded. This happens most of the time when the clientscript have been included.
Case 2 - Server Error:
Server Error in '/' Application.
Exception Details: System.ArgumentException: Empty strings are not allowed.
Parameter name: value
Stack Trace:

Case 3 - Sitecore error:
A required license is missing
Most likely causes:
The resource you are trying to access requires the following license: Runtime.
I'm not sure whether or not Xpress simply doesn't support clientscripts, but even if it doesn't it is weird that some times the content editor loads.
Update after testing in Sitecore 5.4 full version:
It does indeed work to put a script tag inside the <clientscripts> section in web.config as Jens Mikkelsen answered. It is, however, neccessary to put it inside the subsection <everypage> to get it to appear on every single page in the backend, whereas <htmleditor> only works for the Telerik RadEditor popup window in Sitecore 5.4.
Update after testing in Sitecore 6 full version:
The same method as described for Sitecore 5.4 works for Sitecore 6 with the addition of little thing: <script> embedded in <clienscripts> now require a key attribute:
<clientscripts>
<everypage>
<script src="/test.js" language="javascript" key="test script" />
</everypage>
</clientscripts>
I don't think you will be able to add the script with out modifying a file. However you can take a look at the <clientscripts> section in the web.config. There you can add scripts to be loaded. However I don't know if it will only load in the content editor.
I have experimented with this before, and I ended up using the above setting, but as I remember it also loaded on the Page Editor and the Desktop.
Perhaps you can use this example code to add controls to the <head> on the front-end but instead alter it to use the <renderContentEditor> pipeline to somehow inject a new <script> tag into the editor.
here is a good example of it Injecting javascript and css to Sitecore Content Editor Page
