Creating and using a simple Java class

[community_help]

I tried this example with CF10 and I have blank page, no any output. More details : I have created Employee, put as class into ..ColdFusion10\cfusion\wwwroot\uTube\jars\javaapp dir, set ColdFusion Class Path to this location through Administrator and start http://127.0.0.1/uTube/employee1.cfm / As a result, blank page without any output

But Employee object was found, no error about unknown class.

These examples are not appropriate for CF 10 or there is other reason?

Did you do configuration like this in Application.cfc?

this.javaSettings = {LoadPaths = ["\uTube\jars\javaapp\"],loadColdFusionClassPath = "true", reloadOnChange= "true"};

Also, could you show us the Java code in employee1.cfm?

Java classes compiled on JDK1.7 cause this problem because CF10 itself is compiled against JDK1.6.

To solve the problem one needs to (write and) compile his Java classes against JDK1.6. This can be done with JDK1.7 using appropriate flags for compiler. An example:

javac -source 1.6 -target 1.6 Employee.java

It was mentioned though that future updates to CF10/9 would be build for JDK1.7 and in theory this should eliminate the problem.

may be, problem is in location of my custom . class? Where can I locate my classes?

Because only working ( for me) example is this one:

where used standard java.net.InetAddress class...
