i have next jpa entity (generated netbeans):

i seek implement crud operations entity using hibernate lazyevaluationexception. there no references. 1 table in database... can query when seek issue update exception beingness thrown. have naive implementation looks following:

package com.tsystems.tf.dao.impl; import com.tsystems.tf.dao.itestcasedao; import com.tsystems.tf.db.models.testcase; import java.math.bigdecimal; import java.util.collection; import javax.transaction.transactional; import org.apache.catalina.tribes.util.arrays; import org.hibernate.hibernateexception; import org.hibernate.query; import org.hibernate.session; import org.hibernate.sessionfactory; import org.hibernate.transaction; import org.hibernate.boot.registry.standardserviceregistry; import org.hibernate.boot.registry.standardserviceregistrybuilder; import org.hibernate.cfg.configuration; import org.jboss.logging.logger; public class testcasedaoimpl implements itestcasedao { private static final sessionfactory sessionfactory; static { configuration configuration = new configuration(); configuration = configuration.configure(); standardserviceregistrybuilder registrybuilder = new standardserviceregistrybuilder(); registrybuilder = registrybuilder.applysettings(configuration.getproperties()); standardserviceregistry registry = registrybuilder.build(); sessionfactory = configuration.buildsessionfactory(registry); } @override public collection<testcase> getalltestcase() { session session = sessionfactory.opensession(); transaction transaction = null; collection<testcase> testcasecollection = null; seek { transaction = session.begintransaction(); query query = session.getnamedquery("testcase.findall"); testcasecollection = query.list(); transaction.commit(); } grab (final hibernateexception ex) { logger.getlogger(testcasedaoimpl.class) .error(ex.getmessage() + "\n" + arrays.tostring(ex.getstacktrace())); if (transaction != null) transaction.rollback(); } session.close(); homecoming testcasecollection; } @override public void createtestcase(testcase testcase) { throw new unsupportedoperationexception("not supported yet."); //to alter body of generated methods, take tools | templates. } @override public testcase readtestcase(bigdecimal id) { session session = sessionfactory.opensession(); transaction transaction = null; testcase testcase = null; seek { transaction = session.begintransaction(); testcase = (testcase) session.load(testcase.class, id); transaction.commit(); } grab (final hibernateexception ex) { logger.getlogger(testcasedaoimpl.class) .error(ex.getmessage() + "\n" + arrays.tostring(ex.getstacktrace())); if (transaction != null) transaction.rollback(); } session.close(); homecoming testcase; } @override public void updatetestcase(testcase testcase) { session session = sessionfactory.opensession(); transaction transaction = null; seek { transaction = session.begintransaction(); session.update(testcase); transaction.commit(); } grab (final hibernateexception ex) { logger.getlogger(testcasedaoimpl.class) .error(ex.getmessage() + "\n" + arrays.tostring(ex.getstacktrace())); if (transaction != null) transaction.rollback(); } session.close(); } @override public void deletetestcase(bigdecimal testcaseid) { throw new unsupportedoperationexception("not supported yet."); //to alter body of generated methods, take tools | templates. } }

when update beingness called bamm no session. why happening? getall succeeds nice , smooth that's it. else returns in no session error in logs.

replace static block before() method, , add together session creation @ end of :

@before public void before() { configuration configuration = new configuration(); configuration = configuration.configure(); standardserviceregistrybuilder registrybuilder = new standardserviceregistrybuilder(); registrybuilder = registrybuilder.applysettings(configuration.getproperties()); standardserviceregistry registry = registrybuilder.build(); sessionfactory = configuration.buildsessionfactory(registry); session = sessionfactory.opensession(); }

and after() method :

@after public void after { session.close(); sessionfactory.close(); }

and of course, remove open/close session in each test.
