Yes, I solve my problem after hours and hours!

sw-soft faq mentioning to this problem very little and to solve problem forwarded to installation guide documentations.

http://kb.swsoft.com/article_154_565_en.html

the problem accrue because of a amazing conflict!

When trying to restart the application Plesk shows alert "Unable to start up Tomcat web application: Possible reason - Tomcat service is not currently running on the server."

If you have Tomcat and MailEnable Professional installed simultaneously on your server it is a conflicting setup because HTTPMail component of MailEnable Professional and Tomcat share the same port 8080. See the "Post-Installation Issues" section of the Plesk 7.5 for Windows Installation guide for details on how to resolve the conflict.

address of Plesk 7.5 for Windows Installation guide is:

in this documentation, swsoft said:

If you have Tomcat and MailEnable Professional installed simultaneously on your server, it is a

run mmc and open MailEnable Professional management console. There, go to the properties editing
dialog, right click on HTTPMail and go to properties.

Change the value 8080 in the HTTPMail Port edit field to some other value in such way that it
does not coincide with a port used by some other program. For example, change it to 8081.

with these instruction you can easily solve this problem!
