Here is a challenge can't convert Object to int

[Ray Smilgius]

Here is the code:
Error: 500
Location: /inscope/inc/inscopeLayout.jsp
Internal Servlet Error:
org.apache.jasper.JasperException: Unable to compile class for JSPC:\Tomcat\work\localhost_8080%2Finscope\_0002finc_0002finscopeLayout_0002ejspinscopeLayout_jsp_4.java:39: Incompatible type for >. Can't convert java.lang.Object to int.
if ((session.getAttribute("Browser").equals("NETSCAPE")) && ((session.getAttribute("BrowserVer") >= 4))){
I need to compare the Browser Version greater then 4 or equal
Thanks Ray

i assume the getAttribute returns an object which u can convert to string right?
so cast the object to String and then use parseInt on it to turn it into an int.
hope it helps.

Save yourself some trouble. When you store the attribute into the session for the browser version, don't store it as a string. I'm presuming that you're doing this from a "snooper" page since you're looking at session attributes instead of headers here.

// Store the browser version which you placed into String "browserVersion" by
// parsing a header or something.
java.lang.Integer iVersion = null;
try {
    iVersion = new Integer( browserVersion );
    session.setAttribute("BrowserVer", iVersion);
} catch ( NumberFormatException nfe ) {
  // hmmm... It wasn't something like "4.3" was it?
  // Conversion of real-number formats to integers is
  // left as an excercise.   :)  
}

Then on the query end, you can just do:

boolean post40 = false; // assume the worst
Integer iVersion = (Integer) session.getAttribute("BrowserVer");
if ( iVersion != null ) {
  post40 = iVersion.intValue() >= 4;
}
