jpa - Hibernate throws NamingException looking up my datasource into liferay context -


i've liferay (6.1.0 bundled tomcat 7.0.23) portlet use own database different liferay db.

well, if access db tomcat connection pooling works

        string jndiname = "java:/comp/env/jdbc/mydb";            try {          context ctxt = new initialcontext();         name name = ctxt.getnameparser( "" ).parse( jndiname);         datasource ds = (datasource) ctxt.lookup( name ); //i've got datasource      } catch (namingexception e) {         system.out.println("[namingexception]");     }

if use jpa (implemented hibernate 4), throws namingexception. persistence.xml

<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> <persistence-unit name="mypu"> <provider>org.hibernate.jpa.hibernatepersistenceprovider</provider>    <non-jta-data-source>java:/comp/env/jdbc/mydb</non-jta-data-source>     <properties>         <property name="hibernate.show_sql" value="true" />          <property name="hibernate.dialect" value="org.hibernate.dialect.mysqldialect" />          <property name="hibernate.hbm2ddl.auto" value="update" />      </properties> </persistence-unit>

this (simple) code

            entitymanagerfactory emf=persistence.createentitymanagerfactory("mypu");         entitymanager em=emf.createentitymanager();

and relevant part of stacktrace

caused by: org.hibernate.engine.jndi.jndiexception: unable lookup jndi name [java:/comp/env/jdbc/mydb] @ org.hibernate.engine.jndi.internal.jndiserviceimpl.locate(jndiserviceimpl.java:117) @ org.hibernate.engine.jdbc.connections.internal.datasourceconnectionproviderimpl.configure(datasourceconnectionproviderimpl.java:115) @ org.hibernate.boot.registry.internal.standardserviceregistryimpl.configureservice(standardserviceregistryimpl.java:111).

well, downloaded hibernate sources , piece of code of class org.hibernate.engine.jndi.internal.jndiserviceimpl

    public object locate(string jndiname) {     final initialcontext initialcontext = buildinitialcontext();     final name name = parsename( jndiname, initialcontext );     try {         return initialcontext.lookup( name );     }     catch ( namingexception e ) {         throw new jndiexception( "unable lookup jndi name [" + jndiname + "]", e );     }     {         cleanup( initialcontext );     } }

where buildinitialcontext() new initialcontext()

so, seems hibernate , me same thing matter initialcontext different ad lookup hibernate fails.

be in mind context defined under tomcat_home/catalina/localhost. in mind if in persistence.xml don't use tomcat datasource put connection parameters...it works!

        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/mydb" />         <property name="javax.persistence.jdbc.user" value="myuser" />         <property name="javax.persistence.jdbc.password" value="mypwd" />         <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.driver" />

thanks in advance

commonjs - How to write a typescript definition file for a node module that exports a function? -
