Receiving NullPointerException while using Jasypt and Spring Security 3.1 -


i trying configure jasypt spring security. configuration file looks this:

    jdbc.driver=com.mysql.jdbc.driver     jdbc.url=jdbc:mysql://localhost:8090/sample     jdbc.username=enc(*****) *****=the salted username     jdbc.password=enc(*****) *****=the salted password

my servlet xml contains proper bean setup in format:

 <bean id="propertyplaceholderconfigurer"       class="org.jasypt.spring31.properties.encryptablepropertyplaceholderconfigurer">   <constructor-arg ref="configurationencryptor" />   <property name="location" value="/web-inf/jdbc.properties" /> </bean>  <bean id="configurationencryptor" class="org.jasypt.encryption.pbe.standardpbestringencryptor">   <property name="config" ref="environmentvariablesconfiguration" /> </bean>  <bean id="environmentvariablesconfiguration"       class="org.jasypt.encryption.pbe.config.environmentstringpbeconfig">   <property name="algorithm" value="pbewithmd5anddes" />     <property name="passwordenvname" value="app_encryption_password" />   <!--<property name="password" value="**********" />--> </bean>        <bean id="datasource"     class="org.springframework.jdbc.datasource.drivermanagerdatasource">     <property name="driverclassname" value="${jdbc.driver}" />     <property name="url" value="${jdbc.url}" />     <property name="username" value="${jdbc.username}" />     <property name="password" value="${jdbc.password}" />    </bean>

my environment variable set in windows app_encryption_password. visible when echo command line. when use setup, null pointer stack trace below. when use hard coded salt password "-->", application runs smoothly. can show me why jasypt or spring might not picking on environment variable properly? information welcomed. thanks.

for else facing issue , stumbling upon question, restarting eclipse fixed issue.
note: must close eclipse re-open. clicking "restart" won't work doesn't kill java process completely.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
