Stephen Brooksbank updated NETBEANS-5127:
-----------------------------------------
Attachment: messages.log
Description:
I'm getting a null pointer exception when trying to generate database entity
classes using the wizard:
{{java.lang.NullPointerException: Cannot invoke
"com.sun.tools.javac.processing.JavacProcessingEnvironment$DiscoveredProcessors.iterator()"
because "this.discoveredProcs" is null}}
I'm using Apache Derby DB and Wildfly.There are two unmapped entities in the
database (one-to-many relationship), and the persistence context is set up to
use JTA.
What gets generated is two "stub" java class files containing only the basic
class definition without any content
{{package com.brooksbank.weldexamples.db;}}
{{/**}}
* @author sjbro
*/
{{public class Codetypes {}}
{{}}}
The persistance context is :
{{<?xml version="1.0" encoding="UTF-8"?>}}
<persistence
version="2.2"
xmlns="http://xmlns.jcp.org/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
[http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd]";>
<persistence-unit name="com.brooksbank_weldExamples_war_1.0PU"
transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/weldExamplesDS</jta-data-source>
</persistence-unit>
{{</persistence>}}
The datasource is defined in wildfly as:
{\{ <datasource jndi-name="java:/weldExamplesDS"
pool-name="weldExamplesDSPool">}}
\{{
<connection-url>jdbc:derby://localhost:1527/WeldExamplesDB</connection-url>}}
\{{ <driver-class>org.apache.derby.jdbc.ClientDriver</driver-class>}}
\{{ <driver>derbyclient.jar</driver>}}
\{{ <security>}}
\{{ <user-name>******</user-name>}}
\{{ <password>******</password>}}
\{{ </security>}}
\{{ </datasource>}}
The connection to the database works for other database record types and the
wizard pulls up the list of entities correctly to select from.
