spring - Java Standalone (Console) Application - org.hibernate.LazyInitializationException: could not initialize proxy - no Session -

i have searched stackoverflow site , google, , 99.9% of questions web application, i've not found solution java standalone application (runs in linux terminal "java -jar myapp.jar") classic exception "org.hibernate.lazyinitializationexception: not initialize proxy - no session"

my project using spring 4.0.7 + hibernate 4.3.6.final + log4j 1.2.17 + bonecp 0.8.0

i have tried next solutions:

@service , @transactional annotation in client class, , in classes client class calls; @service , @transactional(propagation = propagation.required) annotation in client class, , in classes client class; switched @service @component , retried items 1 , 2 above; tried using transactiontemplate , executing client.start() method within transactioncallback.dointransaction() method; i have tried removing @service , @transactional client class , removing classes called client class.

i've tried , still getting org.hibernate.lazyinitializationexception: not initialize proxy - no session

the comments in code have tried too.

important note: project uses facade class, contains methods used application.

project main class:

bundle com.mycompany.console; import org.springframework.context.applicationcontext; import org.springframework.context.support.classpathxmlapplicationcontext; import org.springframework.stereotype.service; import org.springframework.transaction.annotation.propagation; import org.springframework.transaction.annotation.transactional; @service @transactional(propagation = propagation.required) public class client { private static final logger logger = logger.getlogger(client.class); public static void main(string args[]) { applicationcontext applicationcontext = null; // load spring application context seek { applicationcontext = new classpathxmlapplicationcontext("springhibernateconfig.xml"); final client client = applicationcontext.getbean("client"); // or applicationcontext.getbean(client.class) // tried using transactiontemplate, still getting "org.hibernate.lazyinitializationexception: not initialize proxy - no session" // transactiontemplate transactiontemplate = (transactiontemplate) applicationcontext.getbean("transactiontemplate"); // transactiontemplate.execute(new transactioncallback() { // @override // public object dointransaction(transactionstatus status) { // client.start(args); // homecoming null; // } // }); client.start(args); } grab (exception e) { system.err.println("error loading spring application context: " + e.getmessage()); e.printstacktrace(); system.exit(1); } } private void start(string args[]) { // list, save, update, delete entities // // calls facade.instance().getuserbyid(1l), illustration // // [...] } }

facade class (abdomain):

bundle com.mycompany.domain.facade; @service @transactional(propagation = propagation.required) public class abdomain { public static abdomain instance() { // springutil implements applicationcontextaware homecoming springutil.getapplicationcontext().getbean(abdomain.class); } public user getuserbyid(long id) { /* usuariodao interface, , implementation usuariodaoimpl extends abstracthibernatedao */ homecoming registry.getuserdao().findbyid(id); } }

registry class:

bundle com.mycompany.domain.registry; @component @transactional public class registry { private static applicationcontext applicationcontext; @autowired(required = true) public registry(applicationcontext appcontext) { applicationcontext = appcontext; } public static userdao getuserdao() { homecoming applicationcontext.getbean(userdao.class); } }

edit:

adding stack trace improve understanding.

edit 2:

inbox class called client class (the main class). inbox has no annotation, tried @service @transactional or @component @transactional annotations. i'm looking solution opensessioninviewfilter commonly used in web projects.

after analyzing stack trace, see transactioninterceptor called, possible explication if seek initiale eneityt loaded in diffreent session current one:

so, method call: @ com.mycompany.domain.dao.impl.lastpositiondaoimpl.findlastposition(lastpositiondaoimpl.java:34)

is vehicle entity loaded in different thread/transaction/session , sent in message intercept with:

at com.mycompany.cpr.client.inbox.processmessage(inbox.java:604)

if case, need initialize wanted associations in producer transaction (the 1 fetches vehicle , sends it).
