plus:

i searched lot , messed web.xml , pom.xml , ./settings files , dont remember changes have made 1 thing remember using servlet 2.5 in juno.

any help in right direction appreciative.

update 1:

changed servlet 3.0.1. still getting same error

this facet.core.xml file of ./settings folder.

<?xml version="1.0" encoding="utf-8"?> <faceted-project> <fixed facet="wst.jsdt.web"/> <installed facet="java" version="1.5"/> <installed facet="jst.web" version="2.3"/> <installed facet="wst.jsdt.web" version="1.0"/> <installed facet="jst.jaxrs" version="1.1"/> <installed facet="jboss.m2" version="1.0"/> </faceted-project>

when alter jst.web 3.0 error 1 time again cannot alter project facet web dynamic version 3.0

here:

class="lang-html prettyprint-override"><dependency> <groupid>javax.servlet</groupid> <artifactid>servlet-api</artifactid> <version>2.5</version> </dependency>

it should 3.0 @ to the lowest degree since web.xml specifies version="3.0". maintaining dependency may give conflicts java ee 7.0 dependency here:

class="lang-html prettyprint-override"><dependency> <groupid>javax</groupid> <artifactid>javaee-api</artifactid> <version>7.0</version> <scope>provided</scope> </dependency>

looks you're copying/pasting/crossing fingers , hoping works. not how you're supposed it. import relevant dependencies use.
