java - Hibernate H2 database locks after project rebuild -


i setting spring hibernate h2 application. when server starts works after update (rebuild project in eclipse without restarting tomcat) following error messages saying database file can't accessed.

error messages:

java.lang.illegalstateexception: file locked: nio:/home/bob/datastore.mv.db [1.4.187/7]  java.nio.channels.overlappingfilelockexception  org.apache.commons.dbcp.sqlnestedexception: cannot create poolableconnectionfactory (database may in use:

after googling error tried adding file_lock=no , db_close_on_exit=true url no luck.

context.xml file

<context:annotation-config />     <context:component-scan base-package="com" />      <mvc:annotation-driven />      <mvc:resources mapping="/resources/**" location="/resources/" />       <bean id="datasource" class="org.apache.commons.dbcp.basicdatasource">         <property name="driverclassname" value="org.h2.driver" /> <!--       <property name="url" value="jdbc:h2:tcp://localhost/~/datastore;file_lock=no;db_close_on_exit=true" /> -->         <property name="url" value="jdbc:h2:file:~/datastore;file_lock=no;db_close_on_exit=true;mvcc=true" />          <property name="username" value="" />         <property name="password" value="" />     </bean>      <bean id="sessionfactory"         class="org.springframework.orm.hibernate4.localsessionfactorybean">         <property name="datasource" ref="datasource" />         <property name="packagestoscan" value="com.entities" />         <property name="hibernateproperties">             <props>                 <prop key="hibernate.dialect">org.hibernate.dialect.h2dialect</prop>                 <prop key="hibernate.show_sql">true</prop>                 <prop key="hibernate.enable_lazy_load_no_trans">true</prop>                 <prop key="format_sql">true</prop>                 <prop key="use_sql_comments">true</prop>                 <prop key="hibernate.hbm2ddl.auto">update</prop>             </props>         </property>     </bean>      <tx:annotation-driven transaction-manager="transactionmanager" />      <bean id="transactionmanager"         class="org.springframework.orm.hibernate4.hibernatetransactionmanager">         <property name="sessionfactory" ref="sessionfactory" />     </bean>

what can database not locked every time project rebuilt.

also, eclipse rebuilding application after everytime database updated. how can stop this?

try db_close_on_exit=false, spring docs

if, whatever reason, configure connection url embedded database, care should taken ensure database’s automatic shutdown disabled. if you’re using h2 should use db_close_on_exit=false so.
