java - How to merge jsp pre-compiled web.xml fragment with main web.xml using Ant -

-

we have usual web.xml our web application includes jsp , jsp tag files. want switch using pre-compiled jsp's. have pre-compilation happening in build ok, , generates web.xml fragment , want merge fragment main web.xml.

is there include type directive web.xml let me include fragment.

ideally leave things dev- useful change jsp's on fly , see changes uat/prod, jsp's pre-compiled , work faster.

i use tomcat jasper ant tasks in project, precompile jsps servlets , add new servlet mappings original web.xml. in dev builds, skip step , deploy jsps without pre-compile , modification of web.xml.

    <?xml version="1.0"?> <project name="jspc" basedir="." default="all">  <import file="${build.appserver.home}/bin/catalina-tasks.xml"/>   <target name="all" depends="jspc,compile"></target>   <target name="jspc">   <jasper    validatexml="false"    uriroot="${build.war.dir}"    webxmlfragment="${build.war.dir}/web-inf/generated_web.xml"    addwebxmlmappings="true"    outputdir="${build.src.dir}" />  </target>   <target name="compile">   <javac destdir="${build.dir}/classes"    srcdir="${build.src.dir}"    optimize="on"    debug="off"    failonerror="true"    source="1.5"    target="1.5"    excludes="**/*.smap">    <classpath>     <fileset dir="${build.war.dir}/web-inf/classes">      <include name="*.class" />     </fileset>     <fileset dir="${build.war.lib.dir}">      <include name="*.jar" />     </fileset>     <fileset dir="${build.appserver.home}/lib">      <include name="*.jar" />     </fileset>         <fileset dir="${build.appserver.home}/bin">      <include name="*.jar"/>     </fileset>    </classpath>     <include name="**" />     <exclude name="tags/**"/>   </javac>  </target>   <target name="clean">   <delete>    <fileset dir="${build.src.dir}"/>    <fileset dir="${build.dir}/classes/org/apache/jsp"/>   </delete>  </target> </project>

if have jsp compilation working , want merge web.xml files, simple xslt written add selected elements(such servlet mappings) newly generated web,xml original.

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
