Re: [json-lib-user] java.lang.NoSuchMethodException

[Eric K. <eri...@gm...>]

The relevant source is all in the same file - so there should not be a 
classpath issue there.

I have checked the classpath and have moved all the relevant jars to the 
beginning:

json-lib-2.4-jdk15.jar
commons-beanutils-1.8.0.jar
commons-collections-3.2.1.jar
commons-lang-2.5.jar
ezmorph-1.0.6.jar

Still I get the same error. From within Eclipse, I can see that I am 
calling json-lib-2.4-jdk15.jar and these are exactly the same libraries 
used in my stand-alone program that works. Sadly while my stand-alone 
project uses Maven, the legacy project does not, but I have checked 
several times now and everything should be kosher.

Any other suggestions?

I am tempted to try to use |NewBeanInstanceStrategy| as mentioned in 
http://json-lib.sourceforge.net/advanced.html but neither the 
documentation nor the javadoc has any clarity on what this means. An 
example somewhere would be nice.

Cheers, Eric
