Compilation with Java 6 (1.6) is a bit more involved. I wrote a simple shell script, the important thing here is to get the classpath flag correct. Java veterans will of course have no problem with this, but it took me a few minutes to sort out.

#!/bin/bash
rm -rf output/
javac -classpath "../share/hadoop/lib/commons-cli-1.2.jar:../share/hadoop/hadoop-core-1.0.0.jar" -d classes src/WordCount.java
jar -cvf wordcount.jar -C classes/ .
../bin/hadoop jar wordcount.jar org.apache.hadoop.examples.WordCount input output

Anyway decided not to use it but I did sort out a problem with 1.1.0.0 (as of November 2010) where ASP.NET MVC 2 Areas simply did not work with the view engine.  I suspect this is also the same reason why NHaml doesn’t work with Areas as well.

In the source for Spark in the Spark.Web.Mvc assembly within the DefaultDescriptorBuilder class around line 183 I’ve replaced the methods PotentialViewLocations, PotentialMasterLocations and PotentialDefaultMasterLocations with the following code:

protected virtual IEnumerable<string> PotentialViewLocations(string controllerName, string viewName, IDictionary<string,object> extra)
{
    if (extra.ContainsKey("area"))
    {
        return ApplyFilters(new[]
        {
        controllerName + "\\" + viewName + ".spark",
        "Shared\\" + viewName + ".spark",
        "~\\Areas\\" + extra["area"] + "\\Views\\Shared\\" + viewName + ".spark",
        "~\\Areas\\" + extra["area"] + "\\Views\\" + controllerName+ "\\" + viewName + ".spark"
        }, extra);
    }

    return ApplyFilters(new[]
    {
        controllerName + "\\" + viewName + ".spark",
        "Shared\\" + viewName + ".spark",
    }, extra);
}

protected virtual IEnumerable<string> PotentialMasterLocations(string masterName, IDictionary<string, object> extra)
{
    if (extra.ContainsKey("area"))
    {
        return ApplyFilters(new[]
        {
            "~\\Areas\\" + extra["area"] + "\\Views\\Layouts\\" + masterName + ".spark",
            "~\\Areas\\" + extra["area"] + "\\Views\\Shared\\" + masterName + ".spark",
            "Layouts\\" + masterName + ".spark",
            "Shared\\" + masterName + ".spark"
        }, extra);
    }

    return ApplyFilters(new[]
    {
        "Layouts\\" + masterName + ".spark",
        "Shared\\" + masterName + ".spark"
    }, extra);
}

protected virtual IEnumerable<string> PotentialDefaultMasterLocations(string controllerName, IDictionary<string, object> extra)
{
    if (extra.ContainsKey("area"))
    {
        return ApplyFilters(new[]
        {
            "~\\Areas\\" + extra["area"] + "\\Views\\Layouts\\" + controllerName + ".spark",
            "~\\Areas\\" + extra["area"] + "\\Views\\Shared\\" + controllerName + ".spark",
            "Layouts\\Application.spark",
            "Shared\\Application.spark"
        }, extra);
    }

    return ApplyFilters(new[]
    {
        "Layouts\\" + controllerName + ".spark",
        "Shared\\" + controllerName + ".spark",
        "Layouts\\Application.spark",
        "Shared\\Application.spark"
    }, extra);
}

This doesn’t work with Hanselman’s Mobile Device Capabilities ViewEngine out of the box, you’ll have to do more work for that.

If you don’t want to go through the legwork of patching Spark 1.1.0.0 I’ve zipped up a Release build of the relevant files from my patch.

I had to dig pretty deep for the original solution.

foreach (var key in _headers.AllKeys)
{
    // of course MS would have to fuck this up somehow
    var value = _headers[key];
    Log.Debug(key + ": " + value);
    switch (key.ToUpper())
    {
        case "ACCEPT": _webRequest.Accept = value; break;
        case "REFERER": _webRequest.Referer = value; break;
        case "USER-AGENT": _webRequest.UserAgent = value; break;
        case "TRANSFER-ENCODING": _webRequest.UserAgent = value; break;
        case "DATE":
            if (DateTime.TryParse(value, out dt))
                _webRequest.Date = dt;
            break;
        case "IF-MODIFIED-SINCE":
            if (DateTime.TryParse(value, out dt))
                _webRequest.IfModifiedSince = dt;
            break;
        case "CONTENT-LENGTH":
            int cl;
            if (Int32.TryParse(value, out cl))
                _webRequest.ContentLength = cl;
            break;
        default:
            _webRequest.Headers.Add(key, _headers[key]);
            break;
    }
}

It should be what I originally tried:

//_webRequest.Headers.Add(_headers);

This is precisely the sort of code that creates a great dissatisfaction within me when working with the .NET Framework.

I’ve been reading it when I have a moment here and there and so far its been great. 

1. Jailbreak iPhone if you haven’t done so already.  Very important to change your root and mobile user passwords – root’s password by default is `alpine’ - either by installing Cydia’s Terminal application or sshing into your phone.  (Jailbreaking is a time consuming process and I feel guilty about putting it as a single step.)
1. You will need to install OpenSSH so you can copy files to the phone; you will probably also want to install Terminal.  Both of these applications are available for free within Cydia, just search for them and install.  It will take a long time for your very first ssh connection to your phone to connect as its generating encryption keys.
2. Install the free Kindle app on the iPhone from the iTunes store.
   1. The Kindle stores its books in an `eBooks’ folder buried in the `/var/mobile/Applications/…/Documents/eBooks’ where the `…’ is a GUID identifying the application.
3. SSH (preferably a client where you can copy and paste) or Terminal.
   

   find -type d /var/mobile/Applications -name 'eBooks'

   1. a. Copy the GUID, and you’ll want to end up with the path in 2.1, above, but where the `…’ is replaced by the GUID.  (On my device the GUID was 127DF7F1-9B49-423B-9FA9-77AB87775E24 but I don’t know if this is the same across devices; probably not.)
4. This is purely for convenience, mainly because I want to use WinSCP to copy files from my Windows 7 PC to my iPhone and I don’t want to remember the GUID for the Amazon application every time I want to do this.  (You can also use command line scp, but you’ll likely still want to create a symlink.) (You may also want to use `/private/var/root/Media/eBooks’ if you prefer a better organizational hierarchy.)

   ln -s /var/mobile/Applications/YOUR_GUID/Documents/eBooks \
   /private/var/root/eBooks

5. Now you can use WinSCP or scp to copy *.mobi files directly into your device’s `/private/var/root/eBooks’ directory; books you copy here will be available in the Amazon Kindle iPhone app next time you launch it.
