Hi,
I am constructing an url like below and trying to get the JSON objects.

I get the following error.

Error retrieving library list java.lang.IllegalArgumentException: Invalid uri 'http://test.ntu.edu.sh/libs/sample name/list/json': escaped absolute path not valid

If I paste the above URI on an browser, it goes through and I get the JSON object.
How to introduce a white space between "sample" + " " + "name" as the above construction doesn't pass.
Many Thanks in advance.

edit Which you could have discovered by reading the API for java.net.URL. You would also have discovered an alternative approach.
