Cannot perform web service invocation...

[spellbmw]

This web service has been working correctly for five months but began to fail intermittenly with this error, requiring a restart of the JRun server instance hosting ColdFusion 8. Any ideas?

Have you found an answer for this problem?

Because I have a similair problem. I'll talk about the background.

Through the use of a webservice I call a service object called SecuritySO and a method in there called signOn. In the method signOn everything works like a charm and in the end it returns a structure called user.

That's when the above error is thrown.

I use ColdFusion 8.01

No resolution yet for this issue and still have Adobe technical support trying to figure it out.

Having the same issue in CF 7. Any ideas?

[Meddle69]

Any update on this issue?  I'm experiencing the same thing with CF 8.01

Have you verified that remote debugging is turned off on the server?  a <br><pre> tag looks a little suspicious in your error statement.  Make sure all in-line debugging options are turned off and try again.

We're having a similar problem with our CF7-based web service. It works fine after restarting the server for a while, then one of our clients starts getting the following (obviously server-side) error:

faultDetail:

{http://xml.apache.org/axis/}stackTrace:coldfusion.xml.rpc.CFCInvocationException: [java.lang.ClassCastException : tafkan.remote_api.pfapi.v.trunk.rsp_void]

at coldfusion.xml.rpc.CFComponentSkeleton.__createCFCInvocationException(CFComponentSkeleton.java:714)

at coldfusion.xml.rpc.CFComponentSkeleton.__cast(CFComponentSkeleton.java:405)

at remote_api.pfapi.v.trunk.pfapi.assign_roles_to_user([...]/tafkan/trunk/remote_api/pfapi/v/trunk/pfapi.cfc)

This seems to be happening on a createObject('component', 'rsp_void') call. rsp_void.cfc lives in the same directory as pfapi.cfc, but it looks like it's coming up with two different names for this object and thinks it can't cast one to the other.

Did you ever get anywhere with this?

I suspect you guys are attempting to pass native Coldfusion types like an XML document object or a struct as an argument to the web service. In general, that wouldn't work.

[Meddle69]

No all of the arguments to my webservice cfc's are simple objects or arrays and the consuming application is PHP not CF. This is a completely intermittent issue that when arises continues until the CF service is restarted and is something that Adobe will need troubleshoot and fix. Unfortunately I was unwilling to pay the big bucks to get Adobe to officially look into this and have resorted to just restarting the webserver once in a while when the issue arises since the web service is not mission critical to my business. I'm hoping that Adobe will have axed this issue with Cold Fusion 9 since it's been reported numerous times and makes running a production web service under CF impossible.

Hear hear!

We already rewrote our entire API to remove the structs we were using in the first version. We have simple scalers, arrays, and CFC datatypes, and the whole API works great until it doesn't.

We're now trying to fully-qualify all of our custom type references to see if we can get around this seemingly ambiguous naming problem.

That's the kind of thing I was warning against. What you call simple objects or arrays in Coldfusion may turn out to be neither simple objects nor arrays when they enter the web service or when they are converted into other languages. The surest bets are strings and numbers.

I just wanted to mention that I've cross-posted this discussion at the following places:

http://www.houseoffusion.com/groups/cf-talk/thread.cfm/threadid:60922 (this is the most active discussion)

http://stackoverflow.com/questions/2300776/serious-intermittent-problem-with-cf-web-service

Also, we've gotten nowhere on this. Our next step is to start evaluating alternative CFML servers. I'm really tired of Adobe's Coldfusion and it's closed-source, inscrutable, unsolvable problems.

Hi, I know this is an old post but I am hoping someone has found a solution to this problem. My site is on CF 8. We have a webservice that a .NET application is consuming and they get this error intermittently - for no reason - and restarting the services is the only solution currently.

Is there no programmatic way of resolving this issue? Has anyone tried programmatically clearing the template cache when this error occurs and then retrying the webservice. Any help on this will be DEEPLY appreciated.

[Guest]

p_cfdeveloper, we never found a solution to this problem other than to drop SOAP completely. We re-wrote our webservice in a RESTful style with simple JSON inputs and outputs. Now it operates just like any other request to CF, with no magical SOAP craziness. It works great!

Yes, four and a half years is very old in software terms. So, start your own - new! - thread!
