Have you embedded a servlet jar into your war or ear? If so, you may be having classloader conflict issues.  Remove that jar from your deployment, and wildfly will automatically make the servlet classes visible to your war deployment.

i did'nt have an servlets. can you plase tell me where i have to check.

[samajaypal2]

i did'nt have any servlet jars. in my src lib folder. can you please tell me  where can  i  change or where can modify the javax.servlet.servlet jar in wildfly.

[jewellgm]

If you have the web subsystem configured in your standalone.xml, then your war should have automatic visibility to the servlet jar embedded inside wildfly.  Be sure to check your ear and war for the servlet jar in the following locations:

<ear file>/lib

<ear file>/<war file>/WEB-INF/lib

If you find it in either of those places, remove it.
