DirectCFM: A ColdFusion Server-side Stack

[Gjslick]

Hey Aaron, just posted my application instantiated version of the stack. It's located here: http://www.extjs.com/forum/showthread.php?p=418346. It was really originally just for the implementation of my site, but I tried to make customizable enough for others as well. Anyway, take a look and let me know what you think

Thanks again for your great example stack btw, really got me going on this.

I ran over my project recently with the VarScoper tool, and it found a few missed vars.

Patch attached.

Dear Aaron Conran,


In version v0.1 DirectCFM, when I run the code on a server Coldfusion 9 it is returning the following exception:


18:08:23.023 - java.lang.NegativeArraySizeException - in C: \ wamp \ www \ cfdirect \ ServiceBus \ Direct.cfc: line 13


The line in question is the following:
var byteArray = CreateObject ("java", "java.lang.reflect.Array"). newInstance (byteClass, size);


The DirectCFM be incompatible to the ColdFusion 9?


Sincerely,

Vitor,

I'm not sure what is causing your issue, but it isn't CF 9 itself. I wrote the Ext Direct chapter of Learning Ext JS 3.2 using ColdFusion 9 for the sample code, and all worked well. You may want to look deeper, like did you add the custom attributes to your component and methods?

CutterBi,


Excuse me, the problem was lack of attention. The path was wrong.


It worked perfectly now, and I noticed that not all the original files on Aaron Conran run directly in browser.


When you run the link http://localhost/cfdirect/servicebus/Api.cfm the return of the browser:

Ext.ns('Ext.ss');Ext.ss.APIDesc = {"url":"servicebus\/Router.cfm","namespace":"Ext.ss","type":"remoting","actions":{"echo":[{"len":1,"name":"send"}],"gridExample":[{"len":1,"name":"addGame"},{"len":2,"name":"updateGame"},{"len":1,"name":"deleteGame"},{"len":4,"name":"getGames"}]}};

When you run the link http://localhost/cfdirect/servicebus/Direct.cfc, I'm redirected to the CFCExplorer Coldfusion Application Server.


And when running http://localhost/cfdirect/servicebus/Router.cfm link, I get the following message:

Error Occurred While Processing Request

The error occurred in C:\wamp\www\cfdirect\servicebus\Direct.cfc: line 10 8 : var emptyByteArray = createObject("java", "java.io.ByteArrayOutputStream").init().toByteArray();9 : var byteClass = createObject("java","java.lang.Byte").TYPE;10 : var byteArray = createObject("java","java.lang.reflect.Array").newInstance(byteClass, size);11 : GetPageContext().getRequest().getInputStream().readLine(byteArray, 0, size);12 : createObject('java', 'java.lang.System').out.println("{GetJSONRequest} ByteArray.ToString=" &ToString( byteArray ) ); Resources: Check the ColdFusion documentation to verify that you are using the correct syntax.

My development environment is as follows:
- 2.40GHz Core I3
- 4GB DDR3
- 1 TB SATA HD
- Windows 7 64 Bit
- Coldfusion 9 64 Bits
- Apache 2.2.21


Does it have any problem in this environment or Router.cfm can not really be directly accessed?
