i have tried put 

<constant name="struts.devmode" value="false" />

but exception still there. please help.

as first step try this:

but aware unsafe , see if reason current problem! may try while beeing offline , imediatly remove after test!

go jre installed = {jre_home} go subfolder:

/lib/security/java.policy (e.g. {jre_home}/lib/security/java.policy)

inside file add: grant { permission java.security.allpermission; };

this allow programm executed jvm basicially anything!

so if should work know has java-permissions have read , configure according needs.

in case needs never grant above general permission make sure not leave above entry in java.policy files after quick check if that!
