java - org.springframework.orm.hibernate4.HibernateSystemException: illegally attempted to associate a proxy with two open Sessions -

i getting org.springframework.orm.hibernate4.hibernatesystemexception: illegally attempted associate proxy 2 open sessions exception while update entity. tried many ways configure transaction manager, still getting same. not getting did mistake... :(

category.java

@entity @table(name = "oc_category") public class category implements java.io.serializable { private long categoryid; private string image = "web-resources/image/no_image-45x45.png"; private integer parentid = 0; private integer column = 1; private integer sortorder = 0; private boolean status = false; private date dateadded; private date datemodified; private categorydescription categorydescription; @id @generatedvalue(strategy = generationtype.auto) @column(name = "category_id", unique = true, nullable = false) public long getcategoryid() { homecoming categoryid; } . . . @onetoone(cascade=cascadetype.all) @joincolumn(name = "category_desc_id") public categorydescription getcategorydescription() { homecoming categorydescription; } .

categorydescription.java

@entity @table(name = "oc_category_description") public class categorydescription implements java.io.serializable { private long categorydescid; private string name; private string description; private string metatitle; private string metadescription; private string metakeyword; private language language; private store store; @id @generatedvalue(strategy=generationtype.auto) @column(name = "category_desc_id", unique = true, nullable = false) public long getcategorydescid() { homecoming categorydescid; }

from controller calling categoryservice.save(category); save method

my service impl class is

@service public class categoryserviceimpl implements categoryservice { @autowired @resource(name="categorydao") private categorydao categorydao; public void setcategorydao(categorydao categorydao) { this.categorydao = categorydao; } @transactional public void save(category entity) { categorydao.save(entity); } }

dao impl is

@repository(value = "categorydao") public class categorydaoimpl implements categorydao{ @autowired sessionfactory sessionfactory; @override public void save(category entity) { seek { sessionfactory.getcurrentsession().saveorupdate(entity); } grab (exception exception) { exception.printstacktrace(); } } }

and config file

<tx:annotation-driven /> <context:component-scan base-package="com" /> <context:property-placeholder location="classpath:database.properties" /> <mvc:annotation-driven /> <bean id="datasource" class="org.springframework.jdbc.datasource.drivermanagerdatasource"> <property name="driverclassname" value="${database.driver}" /> <property name="url" value="${database.url}" /> <property name="username" value="${database.user}" /> <property name="password" value="${database.password}" /> </bean> <bean id="sessionfactory" class="org.springframework.orm.hibernate4.localsessionfactorybean"> <property name="datasource" ref="datasource" /> <property name="annotatedclasses"> <list> <value>com.beingjavaguys.domain.employee</value> <value>com.cart.model.category</value> <value>com.cart.model.categorydescription</value> <value>com.cart.model.language</value> <value>com.cart.model.store</value> </list> </property> <property name="hibernateproperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.mysql5dialect</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> </props> </property> </bean> <bean id="transactionmanager" class="org.springframework.orm.hibernate4.hibernatetransactionmanager" p:sessionfactory-ref="sessionfactory"> </bean>

saving new category, categorydescription working fine, while nail on edit , save again, getting org.springframework.web.util.nestedservletexception: request processing failed; nested exception org.springframework.orm.hibernate4.hibernatesystemexception: illegally attempted associate proxy 2 open sessions; nested exception org.hibernate.hibernateexception: illegally attempted associate proxy 2 open sessions
