I am trying to develop jBPM spring boot application but getting Unable to lookup JNDI name [jdbc/jbpm-ds] error.
To achieve so, I have used jbpm-7.36.0.Final, Spring-Boot-2.2.6 and jbpm-spring-boot 7.36.0 Final along with spring boot Bitronix api. Below is my pom.xml
<dependencies>
<dependency>

</dependency>
<dependency>
<groupId>org.kie</groupId>
<artifactId>jbpm-spring-boot-starter-basic</artifactId>
<version>${runtime.version}</version>
</dependency>
</dependencies>
In my application.properties file I have configured below values
#hibernate configuration
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect
spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.hbm2ddl.auto=update
#JTA enabled
spring.jta.enabled=true
#bitronix Non-XA transaction manager configuration
spring.datasource.xa.properties.url=jdbc:sqlserver://10.1.5.209:1433;databaseName=MRR3;
spring.datasource.xa.properties.uniqueName=jdbc/jbpm-ds
spring.datasource.xa.properties.username=sa
spring.datasource.xa.properties.password=password_123
spring.datasource.xa.properties.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.xa.data-source-class-name=bitronix.tm.resource.jdbc.lrc.LrcXADataSource
Below is the code snippet
@Bean
public StatefulKnowledgeSession newStatefulKnowledgeSession() throws Exception {
RuntimeEnvironmentBuilder builder = null;
if (usePersistence) {
TransactionManager tm = TransactionManagerServices.getTransactionManager();
entityManagerFactory = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");//Line where Exception occurs
System.out.println(entityManagerFactory.getProperties());
Environment env = EnvironmentFactory.newEnvironment();
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, entityManagerFactory);
env.set(EnvironmentName.TRANSACTION_MANAGER, tm);
builder = RuntimeEnvironmentBuilder.Factory.get().newDefaultBuilder()
.entityManagerFactory(entityManagerFactory)
.addEnvironmentEntry(EnvironmentName.TRANSACTION_MANAGER, tm);
builder.knowledgeBase(readKnowledgeBase);
StatefulKnowledgeSession ksession = JPAKnowledgeService
.newStatefulKnowledgeSession(readKnowledgeBase, null, env);
return ksession;
// builder =
// RuntimeEnvironmentBuilder.Factory.get().newDefaultBuilder()
// .entityManagerFactory(entityManagerFactory);
}
}

I am also interested to know if below understanding of mine is correct or not
- jBPM only supports JTA type transaction i.e. global transaction. You can't use RESOURCE_LOCAL transaction type while integrating jBPM.
- When I say transaction type RESOURCE_LOCAL, means only one datasource transaction will be shared across the application.
- jBPM RuntimeManager uses 'org.jbpm.domain' persistence unit name (Mandatory type) to handle all it's internal table operations.
- All the application specific transaction can be handled by a default persistence unit name i.e.'org.jbpm.persistence.jpa' . This can be override by a custom persistence context.
- JTA is further divided into two types XADatasource type and Non-XADatasource type. XADatasource should be use when datasource is in application server container. And Non-XADatasource is useful for EJB based application.
XADatasource required below configuration
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
and
<property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform" /> <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.WeblogicJtaPlatform" />
Non-XADatasource required below configuration
<provider>org.hibernate.ejb.HibernatePersistence</provider>
and
<property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.JBossAppServerJtaPlatform"/>
Is point 6 or 7 necessary, if so how to without using persistence.xml.
What is the use of below property and what jar has this class
spring.jpa.properties.hibernate.transaction.manager_lookup_class=org.hibernate.transaction.BTMTransactionManagerLookup
