@SPIN: LTL- Formal Verification

To install Spin: download spin from the official website (http://spinroot.com) then do accordingly. Then install iSpin as well, as described in the web site.

Then to make spin working in any directory create set it to the PATH environment variable, as follow: create some directory like /usr/local/bin/spin/ copy the executable spin from the Src* directory to here, and open /etc/bash.bashrc and add to the env't variable as PATH=$PATH:/usr/local/bin/spin then save restart the terminal.
Also iSpin may not work, displaying the error " exec: 3: wish:  not found ". In this case download and install tcl in this way: sudo apt-get install libtcltk-ruby , The n should work. Enjoy with Spin ....

java.lang.NoSuchMethodError: javax.xml.ws.WebFault.messageName()Ljava/lang/String

This is the problem occurred while I am developing the jsp application to consume web service. I used tomcat 7.0.14 and java 1.6.0_22.

Exception in thread "main" java.lang.NoSuchMethodError: javax.xml.ws.WebFault.messageName()Ljava/lang/String;

The solution is:
 - use endorsed mechanism for tomcat. (add the webservices-api.jar file in the catalina_home/endorsed/) directory. then add some configuration in the tomcat. in windows we can click on configure and follow the steps.
some few links talks about it.

Of course,  I spent more time to solve the problem this problem by searching blogs and google. Mosst of the developers encounter the same problem like mine, but they didn't put the short solution.
Firstly I used jdk 7 for developing and running the client application, and the problem occurred here.

After long time, I change my JDK to version 1.6.0_22 and it works.  But, saying there is application that can run on oldest version but not in latest one is strange for me.  Anyways, the problem is solved. ;)
