Issue with MBean method calls with var args

[anshunarang]

I get an exception ( see below ) When I try to invoke ( remote calls ) following methods of MBean .

public List getUniqueRateCurrencyPairs(String... query);

Is there any issue with calling of MBean methods with variable args . I am able to call the methods without var args without any issue .

I am using jboss 4.0.2 .

Thanks for the help .

One work-around would be to use arrays explicitly in calling, or to create a separate method signature that takes arrays of strings only. How are you creating the proxy?

Thanks a lot for your reply . This is a non issue ... jar on app server was changed which had old version of MBean .

Sorry for trouble .
