[cfaussie] Re: Call Java Class (Java Code Attached)
In Java it is possible to create custom constructors for a class. Often these constructors don't take any arguments, but occassionally you come up against a class that needs parameters to initialize properly. In those cases the class's constructors will require arguments: ie using init() will be invalid.In your case this code is valid:cfscript myObj = createObject(java, IceKey).init(3 );/cfscriptbut this isn't: cfscript myObj = createObject(java, IceKey).init(); /cfscriptFor future reference, a Java class's constructor method has the same name as the class. If you think the constructor (init) might require arguments, you can look through the source code for that method. BTW I have no idea what the argument is for, or whether 3 is a good value.CheersBlairOn 3/21/06, Dale Fraser [EMAIL PROTECTED] wrote:What does that mean in english.Regards Dale Fraser -Original Message- From: cfaussie@googlegroups.com [mailto:cfaussie@googlegroups.com ] On Behalf Of Shib71 Sent: Tuesday, 21 March 2006 14:07 PM To: cfaussie@googlegroups.com Subject: [cfaussie] Re: Call Java Class (Java Code Attached) That's because the class doesn't have a no-arguments constructor.

Somehow either your constructor is returning null, which is weird, or you've written 'myObj' funny somehow.I'm not sure what you have done.MarkOn 3/21/06, Dale Fraser [EMAIL PROTECTED] wrote: Ok, ThisscriptmyObj = createObject(java, IceKey).init(javaCast(int, 2));/scriptcfdump var=#myObj# /GETS Error Occurred While Processing RequestVariable MYOBJ is undefined.The error occurred in D:\Tools\Web\test.cfm: line 53 : /script4 :5 : cfdump var=#myObj# / So I'm at another dead end.RegardsDale Fraser -Original Message- From: cfaussie@googlegroups.com [mailto: cfaussie@googlegroups.com] On Behalf Of Mark Mandel Sent: Tuesday, 21 March 2006 15:50 PM To: cfaussie@googlegroups.com Subject: [cfaussie] Re: Call Java Class (Java Code Attached) You will need to do - createObject(java, IceKey).init(javaCast(1, init)); Which will insure the parameter passed to the constructor is an actual int, not a Integer object.
