Confirming that jar files are being loaded
How can I confirm that my JAR files have been loaded in Coldfusion? I'm on CF10.
I'm currently getting this error:
Could not find the ColdFusion component or interface org.apache.batik.transcoder.image.PNGTranscoder.
My site structure goes as follow:
/root
/root/application.cfc
/root/jar/batik-1.7/
In my application.cfc, I have the following code:
<cfset This.javaSettings = {loadPaths: ["jar/"],loadColdFusionClassPath: true,reloadOnChange: true,watchInterval: 2}>
Here is my code in terms of calling everything:

Update #1
I was checking in the administor and found Settings Summary , which listed CF Server Java Class Path . I added the location of my jar files and rebooted the server. Even though the path is present in the class path in the Administrator, I still get that same error.
Update 2
Added the missing attribute "type" and getting the following error:
java.lang.NoClassDefFoundError: org/apache/batik/dom/util/DocumentFactory
Line 554: transcoder = createObject("java", "org.apache.batik.transcoder.image.PNGTranscoder").init();

Update 3
I have this in my application.cfc
<cfset This.javaSettings = {loadPaths: ["jar/"],loadColdFusionClassPath: false,reloadOnChange: true,watchInterval: 2}>
I called onApplicationStart() and still getting that same error.
At this point, I have removed my entry in the ColdFusion Class Path and it's now back to the default value which is empty.
I want it to work loading the jar files using the javaSettings variable as I'm on shared hosting.
Update:
(Summary from chat) Batik 1.7 includes newer versions of two xml parsing libraries that are already bundled with CF 10. Loading both versions will cause a ClassCastException
org.apache.xerces.jaxp.SAXParserFactoryImpl cannot be cast to javax.xml.parsers.SAXParserFactory
To avoid that error, remove these two xml jars from the batik-1.7/lib directory so they are not loaded:
/batik-1.7/lib/xerces_2_5_0.jar
/batik-1.7/lib/xml-apis.jar
Also, loadPaths is not recursive. So if there are any jars contained in subfolders, you must include the path of those subfolders as well. ie
This.javaSettings = {loadPaths: ["/jar/batik-1.7","/jar/batik-1.7/lib"]};
If you make changes to the this.javaSettings , be sure to restart the application to ensure the changes are applied.
Could not find the ColdFusion component or interface
When you use createObject , you need to include the object "type". Otherwise, it uses the default type "component". Meaning CF is searching for a component/cfc with the path you supplied ie "org.apache.batik.transcoder.image.PNGTranscoder". Since your application probably does not contain a cfc with that path, that is why you are getting the error message above.
Add type "java" to all of your createObject calls and it should work:
createObject("java", "org.apache.batik.transcoder.image.PNGTranscoder").init();
