Error converting CF int to JAVA long

[Guest]

Hi,
I am calling a java method in my code that expects a parameter of type long (64 bit).
If I pass a large int from ColdFusion (i.e. 10000000000) I get the following error:

Could not convert the value 1.0E10 to an integer because it cannot fit inside an integer.

I understand that CF integers are 32 bit so I tried to use the javacast function as follows:

TestPaymentVO.setTestAmount(javacast("long", form.testAmt);

but I still get the same error.

Is there ANY way past this????
Any help would be much apprecieated.
Thanks.

Ran into the JavaCast-long problem a while ago & then wrote the following article:

Don't really see a general solution though, my solutions were either to call another function (int-input) or write pieces of code in java to handle the long-datatype there.
For ex. a java-function reveiving a string, converting the string to java-long, then calling the desired java-function.

Okay, I seem to have found a solution to this....
In Coldfusion create a java object of type java.lang.Long and call its init() method.
Then when you are passing it to java call its .longValue() method
For example:

<cfset amt = CreateObject( "Java", "java.lang.Long" ).init(form.bonusAmt)/>
....
PaymentVO.setAmount(amt .longValue());
......
