org.hibernate.QueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken ------------------------------------------------------------------------------------- Key: HHH-1777 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1777 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.1.3 Environment: Hibernate 3.1.3,mysql-5.0.21-win32,mysql-connector-java-3.0.17-ga,jdk1.4.1_05,Struts 1.1,weblogic 8.1,MyEclipse 4.1.1GA Reporter: Ranjit Patil Attachments: AbstractBook.java, Book.hbm.xml, Book.java, BookListAction.java, BookListForm.class, hibernate.cfg.xml, HibernateSessionFactory.java, LibraryManager.java I have two tables book and customer. My index page has two links show book list and Show customer List.Currently I am working on only Book List. It calls BookListAction.java which in turn calls LibraryManager.java in which getAllBooks() has code something like this: public Book[] getAllBooks() { /* will hold the books we are going to return later */ List books = new ArrayList(); /* a Hibernate session */ Session session = null; /* we always need a transaction */ Transaction tx = null; /* get session of the current thread */ session = HibernateSessionFactory.currentSession(); tx = session.beginTransaction(); ----------Exception is thrown when the below line of code is executed--------------------- List tmpBooks = session.createQuery( "select b from Book as b order by b.author, b.title").list(); ----------------------------------------------------------------------------------------------------------------- for (Iterator iter = tmpBooks.iterator(); iter.hasNext();) { books.add((Book) iter.next()); } tx.commit(); return (Book[]) books.toArray(new Book[0]); } In eclipse it runs fine but when i deployed on weblogic i got following error when i clicked the show book list link: org.hibernate.QueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [select b from de.laliluna.library.Book as b order by b.author, b.title] at org.hibernate.hql.ast.HqlLexer.panic(HqlLexer.java:57) at antlr.CharScanner.setTokenObjectClass(CharScanner.java:287) at org.hibernate.hql.ast.HqlLexer.setTokenObjectClass(HqlLexer.java:31) at antlr.CharScanner.(CharScanner.java:42) at antlr.CharScanner.(CharScanner.java:51) at org.hibernate.hql.antlr.HqlBaseLexer.(HqlBaseLexer.java:56) at org.hibernate.hql.antlr.HqlBaseLexer.(HqlBaseLexer.java:53) at org.hibernate.hql.antlr.HqlBaseLexer.(HqlBaseLexer.java:50) at org.hibernate.hql.ast.HqlLexer.(HqlLexer.java:26) at org.hibernate.hql.ast.HqlParser.getInstance(HqlParser.java:44) at org.hibernate.hql.ast.QueryTranslatorImpl.parse(QueryTranslatorImpl.java:232) at org.hibernate.hql.ast.QueryTranslatorImpl.doCompile(QueryTranslatorImpl.java:155) at org.hibernate.hql.ast.QueryTranslatorImpl.compile(QueryTranslatorImpl.java:109) at org.hibernate.engine.query.HQLQueryPlan.(HQLQueryPlan.java:75) at org.hibernate.engine.query.HQLQueryPlan.(HQLQueryPlan.java:54) at org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan(QueryPlanCache.java:71) at org.hibernate.impl.AbstractSessionImpl.getHQLQueryPlan(AbstractSessionImpl.java:133) at org.hibernate.impl.AbstractSessionImpl.createQuery(AbstractSessionImpl.java:112) at org.hibernate.impl.SessionImpl.createQuery(SessionImpl.java:1583) at de.laliluna.library.bl.LibraryManager.getAllBooks(LibraryManager.java:35)
