Im using hibernate search and elastic search as backend . When i config hibernate and hibernatesearch in xml file everything is ok but whene i config it in java class this warning occur and nothing found in my search .
xml config is:
<properties>
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3399/elastic" />
<property name="hibernate.connection.username" value="admin" />
<property name="hibernate.connection.password" value="admin" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.search.default.indexmanager" value="elasticsearch"/>
<property name="hibernate.search.default.elasticsearch.host" value="http://127.0.0.1:9400"/>
<property name="hibernate.search.default.elasticsearch.index_schema_management_strategy" value="CREATE"/>
<property name="hibernate.search.default.elasticsearch.required_index_status" value="YELLOW"/>
</properties>
java class config is :
java.util.Properties settings = new java.util.Properties();
settings.put(org.hibernate.cfg.Environment.DRIVER, "com.mysql.cj.jdbc.Driver");
settings.put(org.hibernate.cfg.Environment.URL, "jdbc:mysql://127.0.0.1:3399/elastic");
settings.put(org.hibernate.cfg.Environment.USER, "admin");
settings.put(org.hibernate.cfg.Environment.PASS, "admin");
settings.put(org.hibernate.cfg.Environment.DIALECT,"org.hibernate.dialect.MySQL8Dialect");

settings.put(org.hibernate.cfg.Environment.POOL_SIZE, "5");
settings.put("hibernate.search.default.indexmanager", "elasticsearch");
settings.put("hibernate.search.default.elasticsearch.host", "http://127.0.0.1:9400");
settings.put("hibernate.search.default.elasticsearch.index_schema_management_strategy", "CREATE");
settings.put("hibernate.search.default.elasticsearch.required_index_status", "YELLOW");
Warning is :
WARNING: request [HEAD http://127.0.0.1:9400/com.radar.elasticsearch.videogame] returned 1 warnings: [299 Elasticsearch-6.8.0-65b6179 "[types removal] The parameter include_type_name should be explicitly specified in get indices requests to prepare for 7.0. In 7.0 include_type_name will default to 'false', which means responses will omit the type name in mapping definitions."]
You are using Elasticsearch 6.8 where types are deprecated. Please refer removal of types for more info,
You need to pass _doc instead of type name otherwise use include_type_name if you are using your own type name in all the API.
Please refer this official blog for more info
If you plan to upgrade without downtime in a rolling fashion, you
should upgrade to 6.8 first, which is the only 6.x release to have
some features like support for the include_type_name parameter, which
is required to upgrade to 7.0 smoothly.
Elasticsearch support in Hibernate Search 5 is experimental and was only tested with Elasticsearch up to version 5.6.
If you need to upgrade to Elasticsearch 7, upgrade to Hibernate Search 6.
Hibernate Search 6 is currently in Beta but offers revamped APIs that will be a much better fit for Elasticsearch.
It also offers new features not found in Hibernate Search 5, such as support for nested documents or the ability to inject JSON directly into your query (to take advantage of more exotic predicates/sorts/etc. not yet supported by the Hibernate Search DSL).
EDIT: Also, you can find information about the compatibility of Hibernate Search with various other components on this page of the official website.

I have an requirement to use Hibernate Persistence instead of OpenJPA Persistence
I searched in google but didn't get information still looking on it.Any body help on this. I am not much expert in Hibernate.
<property name="openjpa.TransactionMode" value="managed"/>
<property name="openjpa.ConnectionRetainMode" value="always"/>
I'm trying to get log4j (I would also be happy to use any logging api as log as it is jpa persistent) use jpa appender.
My persistence.xml looks like this
<persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<class>org.apache.camel.processor.interceptor.jpa.JpaTraceEventMessage</class>
<class>org.apache.logging.log4j.core.appender.db.jpa.converter.ContextMapAttributeConverter</class>
<class>org.apache.logging.log4j.core.appender.db.jpa.converter.ContextMapJsonAttributeConverter</class>
<class>org.apache.logging.log4j.core.appender.db.jpa.converter.ContextStackAttributeConverter</class>
<class>org.apache.logging.log4j.core.appender.db.jpa.converter.ContextStackJsonAttributeConverter</class>
<class>org.apache.logging.log4j.core.appender.db.jpa.converter.MarkerAttributeConverter</class>
<class>org.apache.logging.log4j.core.appender.db.jpa.converter.MessageAttributeConverter</class>
<class>org.apache.logging.log4j.core.appender.db.jpa.converter.StackTraceElementAttributeConverter</class>
<class>org.apache.logging.log4j.core.appender.db.jpa.converter.ThrowableAttributeConverter</class>
<class>com.xxxxxx.lab.logging.ReportEntity</class>
<properties>
<property name="openjpa.jdbc.DBDictionary" value="org.apache.openjpa.jdbc.sql.HSQLDictionary"/>
<!-- value="buildSchema" to runtime forward map the DDL SQL; value="validate" makes no changes to the database -->
<property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema"/>
<property name="openjpa.RuntimeUnenhancedClasses" value="supported"/>
</properties>
</persistence-unit>
As per apidocs:
Many of the return types of LogEvent methods (e.g., StackTraceElement,
Message, Marker, Throwable, ThreadContext.ContextStack, and
Map) will not be recognized by the JPA provider. In
conjunction with #Convert, you can use the converters in the
org.apache.logging.log4j.core.appender.db.jpa.converter package to
convert these types to database columns.
So I added all necessary classes, but it still throws:
java.lang.NoClassDefFoundError: javax/persistence/AttributeConverter
AttributeConverter seems something new in JPA2.1. Are you sure your project is using JPA2.1 instead of any prior version?
Just curious, why are you so insists to use JPA for log persistence? There are plenty JDBC-based solution which works well. I don't see any reason for using JPA solution unless you are going to make use of the logging related entities in your application.
I am getting the following error when using Hibernate:
'hibernate.dialect' must be set when no Connection available
And I am using a datasource for database connection.
The issue could be that you haven't installed the client library for the database you are trying to connect to.
I have a Spring application that does not have a persistence.xml file and therefore no hibernate.dialect declaration.
Once I installed the MySQL Connector/J client library the error went away.
EDIT: I've also gotten this error when the database server wasn't running. Something that often happens now that I run my MySQL server through MAMP.
You will get this issue even if you have your configuration files having proper value but you don't configure it in the code.
I was explaining hibernate, I forgot to use configure() before buildSessionFactory() so I was getting the error.
You might want to recheck it.
Previous code which was giving me error
SessionFactory factory = new Configuration().buildSessionFactory();
Changed code No Error
SessionFactory factory = new Configuration().configure().buildSessionFactory();
This error is hibernate doing a poor job of telling you what went wrong with your attempted connection with database.
In my case it was as simple as having a wrong password in config file.
You need to set the property
hibernate.dialect
In the hibernate (persistence.xml or bean declaration) configuration, the value depends on your database, for example:
Postgres: org.hibernate.dialect.PostgreSQL82Dialect
Oracle: org.hibernate.dialect.Oracle10gDialect
All posible options are listen here
For example, a sample persistence.xml looks like:
<persistence-unit>
...
<properties>
...
<property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />
...
</properties>
</persistence-unit>
Just encountered this issue. In my case it was the hibernate.dialect configuration.I added the following to SessionFatcory config in spring context file:
<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="annotatedClasses">
<list>
<value>com.testapp.service.geolocation.LocationData</value>
<value>com.testapp.service.profiles.Profile</value>
</list>
</property>
<property name="hibernateProperties">
<value>hibernate.dialect=org.hibernate.dialect.HSQLDialect</value>
</property>
</bean>
I had this problem too. The reason was missing <property name="dataSource" ref="dataSource" /> element in <bean id="sessionFactory"> definition.
In some cases just using a wrong name for the database results in this Exception. Hibernate is apparently trying to determine the dialect before doing anything else, and as the DB cannot be reached, the error message comes from the part responsible for the dialect select. Bad error messaging on part of Hibernate.
In the Hibernate configuration dialog has a tab "options" it is possible to select some.
In this case I was using Oracle Enterprise Pack for Eclipse that already had configured connector, but was still getting the error. Select an option on the list was enough to solve.
I had the same errors.
My problem was that I put the hibernate.properties under one package instead of the src.
So my solution to my problem was moving hibernate.properties from package to src.
How can I debug a query built with JPA 2.0 CriteriaBuilder? Is there a way to print out the query that is being executed?
I am developing a web application using NetBeans, MySql, GlassFish. I would avoid starting MySql in debug mode, because it is used also for other applications. JPA provider is EclipseLink.
The same attributes in persistence.xml that also print the SQL that is generated from regular JPQL queries, should also print the SQL that is generated from Criteria queries.
E.g.
For Hibernate (used by e.g. JBoss AS) it's:
<property name="hibernate.show_sql" value="true" />
For EclipseLink (used by e.g. GlassFish) it's:
<property name="eclipselink.logging.level" value="FINE"/>
<property name="eclipselink.logging.parameters" value="true"/>
Also see: How to view the SQL queries issued by JPA?
If you are using Java and Spring, under resources, you can adjust your application.properties file and add the line below:
spring.jpa.show-sql=true
Does any one know, how to configure cache for hibernate with jboss ?
My clear question is I am using JPA and Jboss. Every time I call JPA method its creating entity and binding query.
My persistence properties are
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
<property name="hibernate.cache.provider_class" value="net.sf.ehcache.hibernate.SingletonEhCacheProvider"/>
<property name="hibernate.cache.use_second_level_cache" value="true"/>
<property name="hibernate.cache.use_query_cache" value="true"/>
And I am creating entity manager the way shown below:
emf = Persistence.createEntityManagerFactory("pu");
em = emf.createEntityManager();
em = Persistence.createEntityManagerFactory("pu")
.createEntityManager();
Is there any nice way to manage entity manager resource insted create new every time or any property can set in persistance. Remember it's JPA.
The question is not clear, there are many second level cache providers for Hibernate and they are not application server specific.
To enable the second level cache, you need to set the following properties in Hibernate configuration file hibernate.cfg.xml:
<property name="hibernate.cache.use_second_level_cache">true</property>
And if you want to also enable query result caching:
<property name="hibernate.cache.use_query_cache">true</property>
Then, declare the name of a class that implements org.hibernate.cache.CacheProvider - a cache provider - under the hibernate.cache.provider_class property. For example, to use JBoss Cache 2:
<property name="hibernate.cache.provider_class">org.hibernate.cache.jbc2.JBossCacheRegionFactory</property>
Of course, the JAR for the provider must be added to the application classpath.
That's for the Hibernate side. Depending on the chosen cache provider, there might be additional configuration steps. But as I said, there are many second level cache providers: EHCache, JBoss Cache, Infinispan, Hazelcast, Coherence, GigaSpace, etc.
