I am trying to get a test jsf application to work on the standard jboss 4.2.0 AS server. I am using eclipse as the IDE. I set the build path in my eclipse project to point to jboss/default/lib jar files for hibernate and other required jars. when I deployed the application everythings works as it should until I make a call from a backing bean to query or load a hibernate class. I get the following error: "org.hibernate.MappingException: Unknown entity: com.ipi.InformationPortal.model.People". The configuration snippets are: ########hibernate.cfg.xml################### <?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="mdp-sf"> true <!-- Mapping files --> </session-factory> </hibernate-configuration> ############### hibernate.properties ################# .. ## MySQL hibernate.dialect org.hibernate.dialect.MySQLDialect #hibernate.dialect org.hibernate.dialect.MySQLInnoDBDialect #hibernate.dialect org.hibernate.dialect.MySQLMyISAMDialect hibernate.connection.driver_class com.mysql.jdbc.Driver hibernate.connection.url jdbc:mysql://localhost/myDB hibernate.connection.username username hibernate.connection.password xxxxxxx .. ########### People.hbm.xml ####################### <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated May 27, 2007 7:19:14 PM by Hibernate Tools 3.2.0.beta7 --> <hibernate-mapping package="com.ipi.InformationPortal.model"> </hibernate-mapping> ############# People.java ###################### package com.ipi.InformationPortal.model; // Generated May 27, 2007 7:19:11 PM by Hibernate Tools 3.2.0.beta7 /** * People generated by hbm2java */ public class People implements java.io.Serializable { // Fields private int peopleid; private String firstName; private String middleInitial; private String lastName; // Constructors /** default constructor */ public People() { } /** minimal constructor */ public People(int peopleid) { this.peopleid = peopleid; } /** full constructor */ public People(int peopleid, String firstName, String middleInitial, String lastName) { this.peopleid = peopleid; this.firstName = firstName; this.middleInitial = middleInitial; this.lastName = lastName; } // Property accessors public int getPeopleid() { return this.peopleid; } public void setPeopleid(int peopleid) { this.peopleid = peopleid; } public String getFirstName() { return this.firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getMiddleInitial() { return this.middleInitial; } public void setMiddleInitial(String middleInitial) { this.middleInitial = middleInitial; } public String getLastName() { return this.lastName; } public void setLastName(String lastName) { this.lastName = lastName; } } ############### backing bean call #################### public static suggestionBean getSuggestionBean() { int peopleid = 1; Configuration cfg = new Configuration(); SessionFactory sf = cfg.buildSessionFactory(); String address = randomString(suggestedAddresses); String password = randomString(chars, 8); /* * Insert some hibernate to get the user name from db. */ People p = new People(); Session session = sf.openSession(); p = (People) session.load(People.class, peopleid); password = p.getFirstName(); address = p.getLastName(); session.close(); return(new suggestionBean(address, password)); } ############################################# The hibernate configuration files are at the root of the jsf app. Any input would be greatly appreciated!!
