Hi Andrew,
I ran into this problem once after making a large number of changes to my
bean code.
Essentially the problem was that the bean could not be loaded by the JVM
because the bean referenced classes that did not exist on the server
machine. I am unclear exactly how this results in the "method not found"
error.
Here are the details...
My beans used to reference classes in a particular package,
com.whatever.package1 for instance.
After making a large # of changes to the code I had renamed
com.whatever.package1 to com.whatever.package2 but I still had some
references to com.whatever.package1 in my bean code.
On my development machine the bean still worked fine because I had not
deleted the .class files for com.whatever.package1.
I redeployed my bean on my server machine which did not have the .class
files for com.whatever.package1.
Jonas appeared to start up OK.
I got the "method not found" when a client tried to invoke a bean method.
After deleting all .class files on my development machine I discovered my
error because my bean code would no longer compile.
I fixed all compile problems and redeployed the bean and everything was
fine.
Hope that helps.
