The usage of org apache commons httpclient URI is not strictly an issue  what is an issue is that you target the wrong constructor  which is depreciated   Using just  new URI   string       Will indeed flag it as depreciated  What is needed is to provide at minimum one additional argument  the first  below   and ideally two    escaped  true if URI character sequence is in escaped form  false otherwise  charset  the charset string to do escape encoding  if required   This will target a non-depreciated constructor within that class  So an ideal usage would be as such   new URI   string   true  StandardCharsets UTF 8 toString        A bit crazy-late in the game  a hair over 11 years later - egad    but I hope this helps someone else  especially if the method at the far end is still expecting a URI  such as org apache commons httpclient setURI
