Hi,
Sorry, I'm quite new to Java.
I've stumbled across HttpGet and HttpPost which seem to be perfect for my needs, but a little long winded. I have written a rather bad wrapper class, but does anyone know of where to get a better one?
Ideally, I'd be able to do
String response = fetchContent("http://url/", postdata);
where postdata is optional.
Thanks!
In java if I am looping over the keySet() of a HashMap, how do I (inside the loop), get the numerical index of that key?
Basically, as I loop through the map, I want to be able to get 0,1,2...I figure this would be cleaner than declaring an int and incrementing with each iteration.
Thanks.
Is there a third party library to detect the use of a Java 1.5 library when compiling with a 1.5 compiler with -source 1.4 and -target 1.4? I could use a 1.4 rt.jar in the bootclasspath however I hope there is a better way. To be used, for example, to fail the compile/build if a newer library is used.

In Java I'm trying to test for a null value, from a ResultSet, where the column is being cast to a primitive int type.
int iVal;
ResultSet rs = magicallyAppearingStmt.executeQuery(query);
if (rs.next()) {
if (rs.getObject("ID_PARENT") != null && !rs.wasNull()) {
iVal = rs.getInt("ID_PARENT");
}
}
From the code fragment above, is there a better way to do this, and I assume that the second wasNull() test is redundant?
Educate us, and Thanks

In python I can construct a HTML string without worrying about escaping special characters like < or " by simply enclosing the string in triple quotes like:
html_string = """
<html>
<body>
<p>My text with "quotes" and whatnot!<p>
</body>
</html>
"""
Is there a similar way to do this in Java?

Can someone give a simple example of MapReduce implemented using either java, javascript or actionscript?
