这里简单的记录了 在windows azure上面运行jetty. (--Java,jsp)
Windows azure 提供的Fast CGI支持可以很方便的运行Php程序， Native Code Support的特性，也可以很方便的运行其他您想运行的东西， 当然 还是有一定的限制的。
具体参看： Executing Native Code in Windows Azure and the Development Environment

1.准备材料
Jre 和Jetty.都可以Google下载到.
这里使用jre6 64bit和jetty7的Zip包.
2.上传jre和jetty.
这2个东西也可以打包到项目里面上传，但是那样文件太大了，这里先上传到 Blob里面.一个简单的上传程序：
---
Upload to blobstatic void Main(string[] args)
{
const string config = @"*************";
CloudStorageAccount acct = CloudStorageAccount.Parse(config);
CloudBlobClient blobclient = acct.CreateCloudBlobClient();
var container = blobclient.GetContainerReference("jre6");
container.CreateIfNotExist();
Upload(container);
}
private static void Upload(CloudBlobContainer container)
{
List<string> failed = new List<string>();
string baseDir = @"C:\Temp\jre6\";
var files = GetFiles(baseDir);
foreach (string file in files)
{
try
{
string fileName = file.Replace(baseDir, string.Empty);
Console.WriteLine(fileName);
var blob = container.GetBlobReference(fileName);
blob.DeleteIfExists();
using (FileStream sr = File.Open(file, FileMode.Open))
{
blob.UploadFromStream(sr);
}
Console.WriteLine(fileName + "-OK");
Thread.Sleep(100);
}
catch
{
failed.Add(file);
}
}
foreach (var item in failed)
{
Console.WriteLine(item + "-Failed");
}
Console.WriteLine("All OK");
Console.ReadKey();
}
---
上传jre和jetty到blob.
使用Azure Storage Explorer看看
3.新建一个带有一个worker role的cloud项目.
ServiceConfiguration.cscfg
---
ServiceConfiguration<ServiceConfiguration serviceName="JettyServer" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration">
<Role name="JettyWorker">
<Instances count="1" />
<ConfigurationSettings>
<Setting name="DiagnosticsConnectionString" value="DefaultEndpointsProtocol=https;AccountName=**;AccountKey=**" />
</ConfigurationSettings>
</Role>
</ServiceConfiguration>
---
ServiceDefinition.csdef
---
ServiceDefinition<ServiceDefinition name="JettyServer" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition">
<WorkerRole name="JettyWorker" enableNativeCodeExecution="true">
<ConfigurationSettings>
<Setting name="DiagnosticsConnectionString" />
</ConfigurationSettings>
<Endpoints>
<InputEndpoint name="Jetty7" protocol="tcp" port="9527" />
</Endpoints>
<LocalResources>
<LocalStorage name="Jetty7Home" cleanOnRoleRecycle="false" sizeInMB="1024" />
</LocalResources>
</WorkerRole>
</ServiceDefinition>
---
在worker role里面下载blob上的程序到LocalStorage 里面.并配置运行jetty.
JettyWorker.cs

4.发布程序，查看Trace信息和执行效果.
PS:这里仅仅是记录了一下在Windows azure平台上面运行jetty. demo的代码很乱,还有很多东西也没考虑，比如对jetty运行状况的监控等等.不过，有了Native Code Support ,LocalStorage 的支持，你可以在该平台上运行一些你想的程序了，比如mysql (http://microsoftpdc.com/Sessions/SVC51)
