Well, I'll freely admit that I'm not a plugin expert, but I would guess that
the NullPointerException is being thrown because getFirstElementByPath is
returning null. So:
MbElement element = assembly
.getGlobalEnvironment()
.getRootElement()
.getFirstElementByPath("/Environment/Variables");
if (null != element)
{
if element.getName().equals("Variables")
{
... do something
}
}
else
{
... complain
}
If that's not the problem, then a print of the exception traceback would
pin-point where it was going wrong.

Subject: How to check in a plugin node if an element in a tree exists?
Unfortunately IBM is not describing what happens when calling the method
getFirstElementByPath("/Environment/Variables") and the field Variables does
not exist.
I tried to do the following:
if ( assembly
.getGlobalEnvironment()
.getRootElement()
.getFirstElementByPath("/Environment/Variables")
.getName().equals("Variables")
)
but got a JavaNullPointerException in the catch path of the flow using this
construct in a plugin node.
Is there a better way to test if a field exists or is my statement wrong?
Many thanks for your support
Regards
Markus
