Are you asking if you need to write a Java wrapper class for an existing Java class to use it with CFMX or whether you need to write a wrapper CFC for using an existing Java class with CFMX? I'll go ahead and answer both questions.
Some Java classes are hard to make use of with CF because of Java being a typed language while CF is a typeless language. For example, if a method of a Java class returns a Hashtable it is going to be hard to call it from CF since there is no equivalent in CF. With CFMX this can be fixed by creating a wrapper class in Java that simply calls the desired method and casts the result into a HashMap and then returns the result to CF. CFMX will automatically cast a HashMap into a struct. However, if you aren't using CFMX, you would need to attack the problem a completely different way. One possible solution would be use to a specialized Hashtable class. For an example of this check out the following article I wrote (http://www.devx.com/java/free/articles/liotta01/liotta01-1.asp). On the other hand, if you question was more about using Java classes that were built with CF in mind; then no, you don't need to create a wrapper CFC. I have just found it to be useful to have a well defined interface between my CF and Java code. It doesn't really add much overhead, but could make things easier at a later date depending on how requirements might change. -Matt > -----Original Message----- > From: Paul Hastings [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, June 26, 2002 12:18 AM > To: CF-Talk > Subject: Re: Apache Xindice article > > > I went ahead and wrote a quick CFC just to show how easy it would be. > > You can now go to http://devilm.com/writing.html to download the Java > > class and its associated CFC wrapper. > > is it a fact of life (or my newness to java) that you almost always have > to > write a wrapper class to use java w/cfmx? i've found myself having to > learn > java to use existing classes to extend cfmx's i18n functionality. > > > > --- > Outgoing mail is certified Virus Free. > Checked by AVG anti-virus system (http://www.grisoft.com). > Version: 6.0.372 / Virus Database: 207 - Release Date: 20/6/2545 > > ______________________________________________________________________ This list and all House of Fusion resources hosted by CFHosting.com.
