It seems to be very helpful when developing the OSGI bundle.

http://bndtools.org/

The easy, powerful and productive way to develop with OSGi. Based on bnd and Eclipse.

Type the following command at the OSGI console.

Reference : http://books.google.co.kr/books?id=zgBcBAAAQBAJ&pg=PT255&lpg=PT255&dq=connect+to+equinox+console+using+telnet&source=bl&ots=JE0yDkexpm&sig=ad3nta5ZKFZx9ZIk9h41YlIotu8&hl=ko&sa=X&ei=2aNzVMH0CoqX8QWEsoDYDw&ved=0CDQQ6AEwAzgK#v=onepage&q=connect%20to%20equinox%20console%20using%20telnet&f=false

The following site gives good explanation and examples to show how to modularize existing web applications with OSGI.

http://server.dzone.com/articles/modularizing-existing-web

To make examples to be run, the point is that you should make the new Target definition which loads bundles under [example]/rsp_repository/rsp_target_platform.

and don't forget to copy org.eclipse.pde.http.ui_1.0.0.jar file to the dropins folder under eclipse installed folder.

The following picture shows example.

rsp4j-example-workspace.zip

Target definition can be added by 

Windows > Preferences > Plug-in Development > Target Platform menu.

: Reload command is useful when you copied some bundle to plugin folder newly.

: In the case of locations, variables can be used as below

ex) ${project_loc}\lib 

ex) ${eclipse_home} 

If you specify import packages in the MANIFEST.MF file as below,

Import-Package:

javax.servlet.jsp.jstl.fmt

If no problem is, the specified jar will be added to the Plug-in Dependencies.

If not, check if the jar file including that package is in the target definition folder. This validation can be run at the "Run configuration" dialog as well.

help 

: lists all available commands

ss | grep text

: lists services which matches with text

bundle [bundle id]

: prints detailed information like Id,Status, Data Root and etc.

b [build id]

: prints all meta data related to this bundle

update [bundle id]

: applies newest bundle

diag [bundle id]

: prints diagnose messages

packages [package name]

: lists all the bundles which use the given package. Wild card can be used at package name.

install file:[file path]

: install a bundle into running OSGI environment. 

* [bundle symbolic name] also can be sued instead of [bundle id]

* And more useful console

The following sample shows how to support failover and load balancing using WCF Routing.

WCFRoutingServiceTest_LB.zip

Sorry, but web.config has an error. Same service was specified as backup list so this causes to round robin routing to fail. Fix this problem by yourself.

After setting the URL Rewriter on IIS,  I got the following error from WCF services which were set as  polling duplex or net.tcp protocols.

The reason is that by default, WCF ensures that the To of each Message matches the intended address.

It's simple to resolve this. Set the AddressFilterMode as Any!

[ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]

Here's sample code:

    [ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]
    public class CalculatorService : ICalculator
    {
        public double Add(double n1, double n2)
        {
            return n1 + n2;
        }

        public double Subtract(double n1, double n2)
        {
            return n1 - n2;
        }

        public double Multiply(double n1, double n2)
        {
            return n1 * n2;
        }

        public double Divide(double n1, double n2)
        {
            return n1 / n2;
        }
    }

HTTP Redirect VS URL Rewrite

1. HTTP Redirect

Redirecting sends a HTTP 301 or 302 to the client, 

telling the client that it should try to access the page using another URL. 

The client knows that there is another URL that should be used. 

2. URL Rewrite

Rewriting happens on the server, and simply is a translation of one URL to another, 

that is used by your web application. 

The client does not know that internally there is another URL, 

it just sees the one it sent to the server.

Installing ARR manually without WebPI (Web Platform Installer)

    Refer: http://blogs.technet.com/b/erezs_iis_blog/archive/2013/11/27/installing-arr-manually-without-webpi.aspx

1. Stop IIS

2. Download and install the Web Farm Framework module. 

    2.1 Web Platform Installer 

    2.2 WebDeploy 2.0 

    2.3 http://www.iis.net/downloads/microsoft/web-farm-framework

3. Download and install the External cache 

    http://download.microsoft.com/download/3/4/1/3415F3F9-5698-44FE-A072-D4AF09728390/ExternalDiskCache_amd64_en-US.msi

4. Download and install the URL Rewrite

http://www.iis.net/downloads/microsoft/url-rewrite

5. Download and install the Application Request Routing

http://www.iis.net/downloads/microsoft/application-request-routing

6. Restart IIS

Example

Assume that we want to forward the url ending with "/test" like http://localhost/test to http://localhost:81/. 

The following example shows how to do this.

{R:2} means that the rest of url excepting 'http://host/test' address. You can check this from the test pattern.

☞ Tip 

To check what the problem is when setting the URL rewrite rule, access it in the server that owns the rule. Then, the browser will give you more information. In addition, use fiddler to check the whole access URL.

TinyGet version 5.2

TinyGet 5.2 (TinyGet.exe) is a command-line Hypertext Transfer Protocol (HTTP) client that supports multiple threads and looping. You can use TinyGet to test or to troubleshoot HTTP client-to-server communication. By using TinyGet, you can customize your test request by configuring many different factors, including the authentication method, the HTTP version, and the output format. You can also use scripts that specify looping and multithreading.
