Brian and Stewie from “Family Guy” performing the opening number for the 59th Primetime Emmy Awards and poking fun at the “wide selection of trash” on television.

“You’ve got mega hits like ‘Idol’ where Sanjaya took his bow
Just a little boy from India who made us all say ‘wow’
With a voice that makes you wanna just go out and kill a cow

Here’s the plain situation
A simple declaration
If you want it you can find it on T.V.

You’ve got ‘Scrubs’ on NBC in season seven and a half
With the antics of the loveable and talented Zach Braff
Who reminds us that a sitcom doesn’t have to make you laugh

You can try to deny it
But we can certify it
If you want it you can find it on T.V.

And if you start to crave a brand new T.V. thrill
They’re always brewing up some brand new primetime swill
Like the GEICO ‘Cavemen’

CBS was once a network that was reverent and clean
But today they’ve got some shows that are remarkably obscene
Like the show about a little boy who lives with Charlie Sheen

Oh, there aint nothing to it
You click it on and view it
If you want it you can find it on T.V.

ABC has got a line-up that’s refreshing and alive
With its hits like ‘Desperate Housewives’ just continuing to thrive
And those women look sensational for being sixty-five

No we won’t oversell ya
We merely wanna tell ya
If you want it you can find it on T.V.

Now the peacock’s having trouble simply staying in the race
So I hear they’re bringing ‘Seinfield’ back to save a little face
And I hear Isaiah Washington is taking Kramers place

Oh, you may not adore it
But, boy, you can’t ignore it
If you want it you can find it on T.V.

Now the ‘Sopranos’ is a show I’d recommend
Because you never know just how it’s gonna-

So to sum up the philosophy on which we’re both agreed
All the garbage on the airwaves is a vital thing indeed
‘Cause without it then Americans would have to learn to read

And so up with the curtain
It’s absolutely certain
If you want it you can find it on T.V.”

Finally a WS-Policy that worked. I was trying to do it in the JBOSS and Tomcat when a thought of using weblogic came to my mind. I used weblogic when it was in 7ish and 8ish versions but now it is in 10ish version. It grew up a lot :-D.

I’ve seen the whole workshop so simillar to Eclipse, I believe they use eclipse as their base environment and then integrate their own packages into it. When adding servers to your project, it even let you to add Tomcat servers, but no JBOSS (as I believe since JBOSS bought by Red Hat).

I used this helps / tutorials to do the simple project.

(-) http://ws.apache.org/commons/neethi/index.html

this called Neethi, API provided by the apache for using ws-policy with your web services. It is in 2.0.4th version.

http://edocs.beasys.com/wls/docs92/ConsoleHelp/taskhelp/webservices/ConfigureWSPolicyFile.html

This was the main help for me to associate a WS-Policy to a web service. Although it was for the 9th version but it helped a lot and I could figure out what to do. There were some minor changes in steps that I think anyone can get it while reading that.

http://localhost:7001/console/console.portal?_nfpb=true&_pageLabel=AppApplicationSecurityPage&AppApplicationRolesPortlethandle=com.bea.console.handles.AppDeploymentHandle(%22com.bea%3AName%3DtestWSEAR%2CType%3DAppDeployment%22)

This was  the place  that I added policies to the service, the policy is so simple that answer a request in specific time (e.g 2:30:00 PM to 3:00:00PM) and if not in that time the service called the answer would be something like this :

After a talk with my supervisor and getting deeper into WS-Policy, it seems that it is not only for security policies and can represent all other types of policies as well. The formal description of WS-Policy can be found here.

So the problem was to implement a web service and attach a ws-policy to it. I’ve used to work with JBoss and BEA weblogic workshop but no Tomcat (a little bit). The astonishing thing I found about weblogic was that they were bought by oracle and now you are using oracle bea weblogic workshop. It also provides the simplest way to use WS-Policy with the web services (with this help) you can figure out how easy is attaching a ws-policy to a web service.

Anyway, thinking of open source and being able to have a defence of why did I use an application server, I tried to put the service into Tomcat and/or Jboss. Jboss version 5 is in its Candidate release at the time of my coding While Tomcat has its 6th version coming out.

Tomcat was lighter and took less time to run and start while Jboss has its huge attachments and take almost 3 to 5 minutes on my computer to run. The deployment of the codes is not considered in the times mentioned.

AXIS is an important part of my work done, it is not my work but it is a library that I used. The funny thing about AXIS is that recently it come to version 2 and the community call it AXIS 2 while also having the versions beside it, like AXIS 2 ver 1.4 which at the beginning confused me a lot. I was looking for downloading AXIS 2 but I got to AXIS2 ver 1.4.

Finally within Eclipse, I tried using two version of Tomcat server (both 5.5), JBoss (ver 5, candidate release) and one Tomcat (ver 6.0), I don’t know what was going on but at the beginning I got a lot of exceptions at the time of generation which lead me to this bug (https://bugs.eclipse.org/bugs/show_bug.cgi?id=84843), reading that it should be solved on the later versions but somehow it was not.

After overcoming the errors generated by AXIS, I didn’t get the results I wanted, the results I want want basically being able to generate a web service based on a function / WSDL file. I switched to AXIS2, The reason was basically to be updated with the latest technology besides being compatible with WS-Policy.

After doing that I got to the problem of getting errors like “Servlet.service() for servlet AxisServlet threw exception java.lang.NoSuchMethodError” finding this page (http://blogs.msdn.com/dotnetinterop/archive/2005/03/31/404087.aspx) figured out that this is not only my problem and is for all other ones using AXIS and AXIS2 together.

So I finally implement a web service with the help of AXIS2 on a Tomcat server which is functional, I’m sending soap messages through the interface and getting response, although it is a sayHello example it shows that everything is in place and working. some address like : http://localhost:64825/wsexplorer/wsexplorer.jsp?org.eclipse.wst.ws.explorer=0 the WSDL address was http://localhost:8080/webserviceSH/services/HelloWorld?wsdl . Although it gives some exceptions in the meantime (mentioned above), it is running smoothly.

The only thing remaining is to check if I attach a WS-Policy to it how it behaves, It should be simple like the one Oracle described.

• AXIS : http://ws.apache.org/axis/
• Tutorial Basic : http://www.roseindia.net/webservices/buildingsimplewebservice.shtml
• WS-Policy in BEA Weblogic : http://edocs.beasys.com/wls/docs92/ConsoleHelp/taskhelp/webservices/ConfigureWSPolicyFile.html
• WTP Tutorial : http://www.eclipse.org/webtools/community/tutorials/BottomUpAxis2WebService/bu_tutorial.html

Looking for how to manage to figure out policies relations to the web services, I’ve found out a paper called “A Practical Introduction to WS-Policy“. Out of that you can simply figure out how to write a web service with a WS-Policy attached to it. The WS-Policy needs WS-PolicyAttachment showing how these policies to attached and how to use.

Both of these are XML based files and are easy to interpret.
The only problem with that is WS-Policy is only giving solutions for security policies, like having a specific token or something like that. What I was looking for it was to somehow check the policy behind a web service in all aspects of business process and not only security requirements.

The ones that WS-Policy can talk about is :

• Integrity (digital signatures)
• Confidentiality (encryption)
• MessagePredicate (specifies message parts that SOAP messages must contain)
• MessageAge
• SecurityToken

Darya Dadvar is a Persian singer who put all her good work from different folkloric Persian musical into a 15 minute video, I was astonished seeing non-persian speaking people enjoy this video so much, so this is her and the folkloric music of Iran.

I was wondering in the drools to run an example myself and there were nowhere on the net telling you (or better saying explicitly telling you) that for running the example you need to have a backbone class defined behind it, a class with some simple functions and some variables, it should be in the same package, but it should also be imported to your rule file (.drl).

So a Rule in Jboss Rules (Drools) just play with class attributes and you can not define classes in its environment,  after writing the code for classes you need to come up with rules, the only good thing is that it has an integrated environment that suggests you functions and variables as programming the rules.

Drools Tutorial

I’m now working on Drools, it is a Jboss product (whish itself is now under redhat umbrella).
If you need to run drools on eclipse remember the following things :

1. Compile under java 1.4 only and not upper (till Drools 4.0.3)
2. After making a sample project (for a test purpose) you definitely will get an error message if you don’t manually add org.eclipse.jdt.core_ to your java library

For mor information see the posting below :

1. Same problem and the solution from Jboss
2. A good resource to find out what JavaDialectConfiguration is

I bet most of Persian speaking people can not sing this song to the end.
Just see a video from Persian-Italian girl who can’t speak Persian and sing this song so well.
