calling java class (with JMagick code) from CFML MX

Hi,

I have previously developed applications in CFML calling java
classes using "<cfset createobject>".

Now I have developed a Java application with JMagick and
ImageMagick support.
ImageMagick is a free open source Image Manipulation libraries collection.
JMagick is a JNI (Java Native Interface) provided over
ImageMagick. By installing ImageMagick and Jmagick, I was
able to develop a Java application successfully.

Now, I need to call this JAVA class from CFML, so that I
can develop a CFML application for Image Processing.

This is my java class;
import magick.ImageInfo;
import magick.MagickImage;
import magick.MagickException;
public class imtrail
{
public String execute(String filename,int x,int y)
{
String message = "";
ImageInfo info = null;
MagickImage image1 = null;
try
{
info = new ImageInfo(filename);
image1 = new MagickImage(info);
MagickImage bigger = image1.scaleImage(x,y);
bigger.setFileName(filename);
bigger.writeImage(info);
}
catch(MagickException e)
{
message = e.getMessage();
}
return message;
}
}

This is my CFML code:
<cfset file_name = "c:\\images\\fujifilm.jpg">
<cfset x = 150>
<cfset y = 150>
<cfset myobject = createobject("java","imtrail")>
<cfset message = myobject.execute(file_name,x,y)>
<cfoutput>#message#</cfoutput>

I am getting the error:
Object Instantiation Exception.
An exception occurred when instantiating a java object. The cause of this exception was that: magick/MagickException.

The error occurred in C:\cfmltest\scale.cfm: line 4

2 : <cfset x = 150>
3 : <cfset y = 150>
4 : <cfset myobject = createobject("java","imtrail")>
5 : <cfset message = myobject.execute(file_name,x,y)>
6 : <cfoutput>#message#</cfoutput>

If any one has any idea please help me

Thank you in advance

We have run into the same problem on our sites. We make extensive use of Jmagick/ImageMagick.

I found that if you place the jmagick.jar file in the server path that the jmagick/imagemagick app will run correctly. The server path is typically C:\CFusionMX7\runtime\servers\lib on a typical server installation.

I have also noticed that this problem does not present itself in a j2ee install. Think that is because all java objects are loaded from the j2ee class.

Hi, I am a beginner using JMagic/ImageMagick on Coldfusion MX.. and struggling on intalling it properly on server. I got 'jmagick.dll' file downloaded from their official website. How does it work to generate 'jmagic.jar' file? . do I only need to include this file on path (configured on coldfusion MX adminstrator) setting ? Is there any other website userful in terms of instructing beginner people like me to install, configure and start using it ?

Thanks a lot, and eagerly waiting for your answer.
