Prince can be called from ColdFusion pages using the Java interface or the ActiveX/COM interface, if on Windows.
Start by downloading the Java interface for Prince. This package contains two files: Prince.jar and README.txt.
The Prince.jar file contains the class file that provides the Java interface to Prince (com.princexml.Prince). The README.txt file lists the Java class methods and explains how to use them.
Place the Prince.jar file in a directory of your choice then start ColdFusion Administrator. Under 'Server Settings > Java and JVM', you should find 'ColdFusion Class Path'. Here you can tell ColdFusion where to look for Java classes. Type in the full path of the Prince.jar file. It should be something like: PATH\Prince.jar, where PATH is the path of the directory that contains the Prince.jar.
If this is done correctly, ColdFusion should know where to find the Prince Java interface class. The following is some sample CFML code showing how to use it:
<cfscript> pr = CreateObject("java", "com.princexml.Prince"); pr.init("C:\Prince\engine\bin\prince.exe"); pr.addStyleSheet("C:\Prince\test\test1.css"); pr.addStyleSheet("C:\Prince\test\test2.css"); pr.setEncryptInfo(128, "secretPassword1", "secretPassword2", True, True, True, True); if (pr.Convert("C:\Prince\examples\magic.html", "C:\output.pdf")) WriteOutput("Successful"); else WriteOutput("Unsuccessful"); </cfscript>
If on Linux, substitute the paths with the appropriate UNIX style paths.
If you are running ColdFusion on Windows, you can also call Prince using the ActiveX/COM interface.
This interface is provided in the form of an ActiveX DLL file that needs to be registered in the Windows registry using REGSVR32.EXE:
In order to call Prince from ColdFusion, we need to create a COM object using the CreateObject function that is available in CFML scripting (you can also use the <cfobject ...> tag if you prefer). Once the COM object is created, you can use the COM interface methods to perform the tasks.
The following is some sample code for illustration:
<cfscript> pr = CreateObject("Com", "PrinceCom.Prince", "local"); pr.SetPrincePath("C:\Prince\engine\bin\prince.exe"); pr.AddStyleSheet("C:\Prince\test\test1.css"); pr.AddStyleSheet("C:\Prince\test\test2.css"); pr.SetEncryptInfo(128, "secretPassword1", "secretPassword2", True, True, True, True); if (pr.Convert("C:\Prince\examples\magic.html", "C:\output.pdf") eq 1) WriteOutput("Successful"); else WriteOutput("Unsuccessful"); ReleaseComObject(pr); </cfscript>
Please read the README.TXT file that comes with the ActiveX DLL file for more details of the COM interface methods.
