How to get relative path from UriInfo

I'm working with JAX-RS in Java. I need to get from the UriInfo the relative path of the URI, i.e. the URI without the scheme and authority parts but with path and query parameters. What is the best way to do it?

I needed the exact same thing although few years later. Nevertheless here's how.

URI requestURI = this.uriInfo.getRequestUri();
URI baseUri = this.uriInfo.getBaseUri();
URI uri = baseUri.relativize(requestURI);

check this:

String uri = "http://google.com/path?q1=va";
    int index = -1;
    if ((index = uri.indexOf("://")) > 0) {
        uri = uri.substring(index + 3);
    }
    index = uri.indexOf('/');
    uri = uri.substring(index);
    System.out.println(uri);

or like this:

    URI uri  = new URI("http://google.com/path?q1=va");
    System.out.println(uri.getPath()+"?"+uri.getQuery());

According to https://jsr311.java.net/nonav/javadoc/javax/ws/rs/core/UriInfo.html if you call 

 getPath()

You will "Get the path of the current request relative to the base URI as a string."

String sourceUrl = "http://www.example.com/mysite/whatever/somefolder/bar/unsecure!+?#whätyöühäv€it/site.html"; // your current site
    String targetUrl = "http://www.example.com/mysite/whatever/otherfolder/other.html"; // the link target
    String expectedTarget = "../../../otherfolder/other.html";
    String[] sourceElements = sourceUrl.split("/");
    String[] targetElements = targetUrl.split("/"); // keep in mind that the arrays are of different length!
    StringBuilder uniquePart = new StringBuilder();
    StringBuilder relativePart = new StringBuilder();
    boolean stillSame = true;
    for(int ii = 0; ii < sourceElements.length || ii < targetElements.length; ii++) {
        if(ii < targetElements.length && ii < sourceElements.length && 
                stillSame && sourceElements[ii].equals(targetElements[ii]) && stillSame) continue;
        stillSame = false;
        if(targetElements.length > ii)
          uniquePart.append("/").append(targetElements[ii]);
        if(sourceElements.length > ii +1)
            relativePart.append("../");
    }

    String result = relativePart.toString().substring(0, relativePart.length() -1) + uniquePart.toString();
    System.out.println("result: " + result);
