java.lang.String cannot be cast to [Ljava.lang.CharSequence;

[prhlava]

Hello,

I am trying to use a java library ( http://code.google.com/p/webdriver/
), the method I need to call has signature:

sendKeys(java.lang.CharSequence... keysToSend)

If I give it a clojure string, the "cannot be cast" message appears in
the stack trace.

I have tried explicit (cast java.lang.CharSequence "my-string") but
the cast does only "compare" AFAIK.

Is there a way to give the library what it wants from Clojure?

Kind regards,

Vlad

I would be interested in seeing a full stack trace and some pastbined
code. there are no clojure strings, just java strings, and java
strings are charsequences.

Are you trying to give it a string, or an array of strings?

sendKeys takes a variable number of arguments. The error you are getting is that it can't cast a java.lang.String into [Ljava.lang.CharSequence, where the '[' at the beginning of the type means an array. It is telling you that it cannot convert a String into an array of CharSequences. Maybe it will work with (into-array ["string"])?

Thank you, this was spot on, the correct call looks like:

(. query (sendKeys (into-array ["my-string"])))

Cheers!
