Syntax
<!--- Syntax 1: This syntax invokes a method of a component. --->
<cfinvoke
component = "component name or reference"
method = "method name"
returnVariable = "variable name"
argumentCollection = "argument collection"
...>
OR
<!--- Syntax 2: This syntax can invoke a method of a component only from within the component. --->
<cfinvoke
method = "method name"
returnVariable = "variable name"
argumentCollection = "argument collection"

OR
<!--- Syntax 3: This syntax invokes a web service. --->
<cfinvoke

OR
<!--- Syntax 4A: This syntax invokes a component.
This syntax shows instantiation with the cfobject tag.
This cfinvoke syntax applies to instantiating a component
with the cfobject tag and to instantiating a component
with the CreateObject function. --->

OR
<!--- Syntax 4B: This syntax invokes a web service.
This syntax shows instantiation with the cfobject tag.
This cfinvoke syntax applies to instantiating a web service with the cfobject tag and to
instantiating a web service with the CreateObject function. --->
<cfobject

Note: You can specify this tag’s attributes in an attributeCollection attribute
whose value is a structure. Specify the structure name in the attributeCollection attribute
and use the tag’s attribute names as structure keys.
Attributes
| Attribute | Description | Required | Default |
|---|---|---|---|
| argumentCollection | Name of a structure; associative array of arguments to pass to the method. | Optional | |
| component | String or component object; a reference to a component, or component to instantiate. | See Usage. | |
| input_params ... | Input parameters. For each named input parameter specify paramName=paramValue. | ||
| method | Name of a method. For a web service, the name of an operation. | See Usage. | |
| password | The password to use to access the web service. If the webservice attribute specifies a web service name configured in the Administrator, overrides any user name specified in the Administrator entry. | Optional | Password set in the Administrator, if any |
| proxyPassword | The user’s password on the proxy server. | Optional | http.proxyPassword system property, if any |
| proxyPort | The port to use on the proxy server. | Optional | http.proxyPort system property, if any. |
| proxyServer | The proxy server required to access the webservice URL. | Optional | http.proxyHost system property, if any. |
| proxyUser | The user ID to send to the proxy server. | Optional | http.proxyUser system property, if any |
| refreshWSDL | yes: reload the WSDL file and regenerate the artifacts used to consume the web service no | Optional | no |
| returnVariable | Name of a variable for the invocation result. | Optional | |
| servicePort | The port name for the web service. This value is case sensitive and corresponds to the port element’s name attribute under the service element. Specify this attribute if the web service contains multiple ports. | Optional | First port found in the WSDL |
| timeout | The time-out for the web service request, in seconds. | Optional | 0 (no timeout) |
| username | The user name to use to access the web service. If the webservice attribute specifies a web service name configured in the Administrator, overrides any user name specified in the Administrator entry. | Optional | User name set in the Administrator, if any |
| webservice | One of the following: The absolute URL of the web service WSDL. The Name (string) assigned in the ColdFusion Administrator to the web service. | See Usage | |
| wsdl2javaArgs | A string that contains a space-delimited list of arguments to pass to the WSDL2Java tool that generates Java stubs for the web services. Useful arguments include the following: -W or --noWrapped: Turns off the special treatment of wrapped document/literal style operations. -a or --all: Generates code for all elements in the WSDL, even unreferenced ones. -w or --wrapArrays: Prefers building beans to straight arrays for wrapped XML array types. This switch is not in included in the Axis documentation. For detailed information on valid arguments, see the Apache Axis WSDL2Java Reference. | See Usage |

If the component attribute specifies a component name, the component with the corresponding name is instantiated, the requested method is invoked, and then the component instance is immediately destroyed. If the attribute contains a reference to an instantiated component object, no instantiation or destruction of the component occurs.
On UNIX systems, ColdFusion searches first for a file with a name that matches the specified component name, but is all lower case. If it does not find the file, it looks for a file name that matches the component name exactly, with the identical character casing.
Method arguments can be passed in any of the following ways. If an argument is passed in more than one way with the same name, this order of precedence applies:
Using the cfinvokeargument tag
Passing directly as attributes of the cfinvoke tag (they cannot have the same name as a registered cfinvoke attribute: method, component, webservice, returnVariable)
Passing as struct keys, using the argumentCollection attribute
For example, the params struct contains three keys: a=1, b=1, c=1. The following call is evaluated as if the arguments were passed to the method in the order a=3, b=2, c=1:
<cfinvoke ... a=2 b=2 argumentCollection=params> <cfinvokeargument name="a" value="3"> </cfinvoke> Note: The following cfinvoke tag attribute names are reserved; they cannot be used for argument names: component, method, argumentCollection, and result.
