I'm looking to convert libreoffice java example to cfm but j don't undestand how reference to "XComponentLoader.class" before create it

this row are ok

<cfset OOB = createObject("java","com.sun.star.comp.helper.Bootstrap")/>

<cfset xContext = OOB.bootstrap()>

<cfset xMCF = xContext.getServiceManager()>

<cfset desktop = xMCF.createInstanceWithContext("com.sun.star.frame.Desktop", xContext)>

<cfset UnoRuntime = createObject("java","com.sun.star.uno.UnoRuntime")/>

this is then row to convert

XComponentLoader xCompLoader = UnoRuntime.queryInterface(XComponentLoader.class, xDesktop);

I try:

1)

<cfset xComponentLoader = UnoRuntime.queryInterface(XComponentLoader.class, desktop)>

2)

<cfset myloader = createObject("java","com.sun.star.frame.XComponentLoader")/>

<cfset xComponentLoader = UnoRuntime.queryInterface(myloader.class, desktop)>

3)

<cfobject type="Java" class="com.sun.star.frame.XComponentLoader.class" name="myloader" action="create">

<cfset xComponentLoader = UnoRuntime.queryInterface(myloader, desktop)>

but no one work

any ideas or j've to pass to cfx ?

possibly

<cfset cls = CreateObject("java", "java.lang.Class")>

<cfset xCompLoaderClass = cls.forName("com.sun.star.frame.XComponentLoader")>

or

<cfset XCompLoader = CreateObject("java", "com.sun.star.frame.XComponentLoader")>

<cfset xCompLoaderClass = XCompLoader.getClass()>

then

<cfset xCompLoader = UnoRuntime.queryInterface(xCompLoaderClass, desktop)>

This is just a shot in the dark, I'm not testing this code sample. It looks like your variable names in your code examples don't match up with the ones in the Java code, though.

Java code:

XComponentLoader xCompLoader = UnoRuntime.queryInterface(XComponentLoader.class, xDesktop);

CFML code:

<cfset xCompLoader = createObject("java","com.sun.star.frame.XComponentLoader")>

<cfset xCompLoader = UnoRuntime.queryInterface(XComponentLoader.class, desktop)>

You might be able to string these together using method chaining:

<cfset xCompLoader = createObject("java","com.sun.star.frame.XComponentLoader").UnoRuntime.queryInterface(XComponentLoader.class, desktop)>

it still don't work, with

<cfset xCompLoader = createObject("java","com.sun.star.frame.XComponentLoader")>

<cfset xCompLoader = UnoRuntime.queryInterface(XComponentLoader.class, desktop)>

return the error

Element CLASS is undefined in XCOMPONENTLOADER.

and with

<cfset xCompLoader = createObject("java","com.sun.star.frame.XComponentLoader").UnoRuntime.queryInterface(XComponentLoader.class, desktop)>

return the error

Element UNORUNTIME is undefined in a Java object of type class coldfusion.runtime.StructBean.

<cfset xCompLoaderClass = XCompLoader.getClass()>
