No, you can't. None of the docs day you can.

ROOT is the special name for the default application, which serves
resources from / and handles all requests which are not handled by
other applications.

Putting ROOT inside other apps just results in publishing that whole
dir as /appname/ROOT.

If you don't provide other details of your config, no-one here will be
able to help, without a really, really lucky guess.

Its a virtual host with following lines have been added to main httpd.conf:
LoadModule jk_module          libexec/apache22/mod_jk.so
JkWorkersFile /usr/local/etc/apache22/workers.properties
JkShmFile     /var/log/mod_jk.shm
JkLogFile     /var/log/mod_jk.log
JkLogLevel   debug 
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

and following JkMount directives for each virtual host:
JkMount  /appexmp1/*     appexmp1
JkMount  /appexmp1/*.jsp appexmp1

and following is the worker file for two of the sites:
worker.list=appexmp2,appexmp1
worker.appexmp2.type=ajp13
worker.appexmp2.host=localhost
worker.appexmp2.port=8009
worker.appexmp1.type=ajp13
worker.appexmp1.host=localhost
worker.appexmp1.port=8109


Created separate directories in CATALINA_BASE/webapps/
for each application so , it contain following directories:
CATALINA_BASE/webapps/ROOT
CATALINA_BASE/webapps/appexmp1
CATALINA_BASE/webapps/appexmp2

context file for each application resides in 
CATALINA_BASE/conf/Catalina/localhost for example:
CATALINA_BASE/conf/Catalina/localhost/appexmp1.xml
CATALINA_BASE/conf/Catalina/localhost/appexmp2.xml

cat  CATALINA_BASE/conf/Catalina/localhost/appexmp1.xml
<Context path="/appexmp1" docBase="appexmp1" debug="0" reloadable="true" crossContext="true">
</Context>

and web.xml file as follow:
cat CATALINA_BASE/webapps/appexmp1/WEB-INF/web.xml
<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">
<servlet>
    <servlet-name>App1</servlet-name>
    <servlet-class>com.appexmp1.App1</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>App1</servlet-name>
    <url-pattern>/APP1</url-pattern>
  </servlet-mapping>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

</web-app>


I already can access mydomain.com/App1/index.jsp and every thing works fine
but want to be able to serve .jsp files as follow:
mydomain.com/index.jsp
for each of my virtual hosts.

I hope I have provided enough information.

Thanks for help
