Thanks Pete! For now... we were able to get away with using and passing an integer array. We haven't upgraded to CFMX yet, but are looking forward to better CF/Java integration.
As an interesting side note... we found that if we called our Java object via a cfscript UDF call and looped over that... we ran into a huge bottleneck with its performance... however, calling the Java objects outside of the UDF in a loop performed about 8 times faster in our simple tests (~34 seconds to ~4 seconds). I'm not sure what's really going there, but thought someone out there might know... Thanks again...

Structures in CF5 are in C++ memory land, but in MX they are java objects, so you can pass them around to your own stuff. One workaround is to use WDDX, serialize the structure to WDDX, pass it as a string, and then in the Java class convert the WDDX into a Hashtable. Another workaround would be to create a UDF or something that converted a CF structure into a Java Hashtable by looping through the structure. This would probably perform better than the WDDX solution. _____________________________________________ Pete Freitag CTO, CFDEV.COM http://www.cfdev.com/ -----Original Message----- From: Correa, Orlando (ITSC) [mailto:Orlando.Correa@;mail.ihs.gov] Sent: Wednesday, November 13, 2002 1:44 PM To: CF-Talk Subject: Passing CF5 Structures to Java We are experiencing a problem while trying to pass a ColdFusion 5 structure to a java class that was created using CreateObject. Our java code conceptually looks something similar to: public class javaTest { public static int testThis(Hashtable testVal) { return 7; } } The call in Cold Fusion is like: <cfset request.o_test = CreateObject("JAVA", "javaTest")> <cfloop from=1 to=1000 index="i"> <cfset x = request.o_test.testThis(CFstructure)> </cfloop> where CFstructure is a basic structure (key/value pair) with 2 elements. We have also tried to cast the structure as a HashMap and an Object and get the same error each time. "Unknown exception during conversion of a CF type to a Java type" Can anyone help us with this? Thanks... Anderson, Ryan R.
