I was using JsonPath.read( jo, path ) successfully with paths that includes the forward slash, but then I started creating my JSON by parsing strings using json-simple, which escapes the slash ("/") character.
I thought the solution would be simple: just do the same escaping of my path string, but this doesn't solve the problem.
My Java code looks like this:
public String escapedPath = "$.property.\\/first\\/second.value";
And this produces a path = "$.property.\/first\/second.value", which exactly matches path element in my JSON, but attempting a read with this path produces:
com.jayway.jsonpath.PathNotFoundException: Path '\/first\/second' not found in the current context: ...
Note that having the escaped / at the beginning of an element, having two them, etc. made no difference - I tried many variations. The only thing that makes it work is to return to un-escaped slashes.
I'm using JsonPath 0.9.0 on GAE 1.8.9.
