[digester] No such accessible method

[Erik Price <ep...@ptc.com>]

Hi,

I've been happily using Digester for about six months now, but suddenly 
it's stopped working for me and I just can't figure out why.  I'm hoping 
someone on this list can point out my mistake.

I instantiate a digester instance, push an object instance onto it (of 
type "com.ptc.oatmeal.Criteria") and call a gamut of methods on the 
Criteria.  This works fine.  But one of the methods throws an 
IOException, and when I catch this exception, unwrap it, and log it, it 
is this:

2140 [main] DEBUG org.apache.commons.beanutils.MethodUtils  - Matching 
name=setParentRequirementId on class com.ptc.oatmeal.Criteria
2140 [main] DEBUG org.apache.commons.beanutils.MethodUtils  - Found 
matching name:
2140 [main] DEBUG org.apache.commons.beanutils.MethodUtils  - public

Param=java.lang.String
2140 [main] DEBUG org.apache.commons.beanutils.MethodUtils  - Method=int
2140 [main] DEBUG org.apache.commons.beanutils.MethodUtils  - int is not 
assignable from class java.lang.String
2140 [main] DEBUG org.apache.commons.beanutils.MethodUtils  - No match 
found.
2156 [main] ERROR org.apache.commons.digester.Digester  - End event 
threw exception
java.lang.NoSuchMethodException: No such accessible method: 
setParentRequirementId() on object: com.ptc.oatmeal.Criteria
	at 
org.apache.commons.beanutils.MethodUtils.invokeMethod(MethodUtils.java:250)
	at org.apache.commons.digester.CallMethodRule.end(CallMethodRule.java:505)



How do I cast the String in my XML file (which is simply a number) to an 
integer so I can pass it to the "setParentRequirementId" method?


Thanks,

Erik

Usually, this sort of message is caused by one of the following problems
-- without seeing the source to your Criteria class, there's no way to
know which issue is actually causing this.  Look for:

* The Criteria class must be public.

* The setParentRequirementId() method must be pubic and (it looks like)
  take an int parameter.

* There must be no other setParentRequirementId() method that takes a
  different type of parameter.  In other words, "parentRequirementId"
  must be a proper JavaBeans property with the usual getter and setter
  method names, or you can use a BeanInfo class to explicitly specify
  the getter and setter method names to use.

Pardon me, I somehow missed this overload of the 
org.apache.commons.digester.Digester class.  I used a single-element 
Class[] array with "java.lang.Integer" and it worked.
