i uploaded this project folder, i hope to find any one to help me to find why this app doesn't run, so sad and angry of this problem, bcz i tried a lot of solutions and no hope also i'm sorry if the file size is large (19mb) but it's bcz i attached all jar's with the project

the problem was that i missed the file "commons-lang3-x.x.x.jar" and when i tried to solve i added all the files which made conflict problem

so my advice use just jar's that you need

and the files that you need for helloWorld app is

commons-fileupload-x.x.x.jar
commons-io-x.x.jar
commons-lang-x.x.jar
commons-lang3-x.x.x.jar
commons-logging-x.x.x.jar
commons-logging-api-x.x.jar
freemarker-x.x.x.jar
javassist-3.x.x.GA.jar
ognl-3.x.x.jar
struts2-core-x.x.x.x.jar
xwork-core-2.x.x.x.jar

my best wishes :D and thanx indeed for you
