ObjectDB Database Search

The drop code word does not work?

Hello! I use ObjectDB with Spring. Today i tried to swich from AspectJ compile time weaving to load time weaving . (To get Jrebel working properly) So i added      To my context.xml and to my spring configuration. Now Spring oviously tries to weave every class that get's loaded

the new ObjectDB build load time weaving (enhancement) by Spring is currently disabled ... know i'm not using loadtime weaving but compile time weaving with aspectj) anyway, i got a spring ... ) to gain performance. I wonder what would happen if you would enable Spring load time weaving

weaving . Unluckily the LTW option of Spring is global. If it's enabled it also tries to find other class ... an exception which causes Spring to stop weaving .  Caused by: com.objectdb.o.InternalException ... the exception and output a log message like "Java 8 weaving currently not supported." instead

; support Support Attached please find the test code . The screen output is at the end of the post ... for all object Goods successfully] 04 SELECT u FROM Goods u where u._ code like : code AND u._desc like :desc  05 code = %, desc= % 06 UI: end query 07 UI: start printing result 08 code = A, desc= Good

get the last part of the tutorial: "To enable on the fly automatic enhancement ( weaving ) in Tomcat ... enhancement ( weaving ) is automatically enabled without specifying a Java agent." P.S: I was using

- start writing more effective database code using Java classes and objects! Try an ObjectDB / JPA

Entity Classes Storing an entity object in the database does not store methods and code

databases when necessary - with exactly the same code .

Given an EntityManager , em , that represents a JPA connection to the object database, we can use it to store, retrieve, update and delete database objects. Storing New Entity Objects The following code fragment stores 1,000 Point  objects in the database: em. getTransaction (). begin

and the code is simple: Query query = em. createQuery ("SELECT COUNT(c) FROM Country c"); long countryCount

. get ("capital"); Path captialName = capital. get ("name"); The path expressions in the above code

a PESSIMISTIC_READ lock on that database object. For example, consider the following code fragment: em1

and menus might look slightly different but the code would be the same). The tutorial is based on using

and paste to replace the new source file content with the following code : package guest; import

to create the class. Copy and paste the following code to the newly created class file: package

In this step we will add code to the Main class (that was generated with the project) in order to store Point objects in the database and then retrieve them from the database. Use copy and paste to replace the content of the Main class with the following content: package tutorial; import javax

replace the content of the new source file with the following code : package guest; import javax.servlet

with other Eclipse versions as well (dialog boxes and menus might look slightly different but the code

but the code would be the same). The Tutorial Steps This tutorial consists of the following steps:

to replace the new source file content with the following code : package guest; import java.io

and paste to replace the new source file content with the following code : package guest; import java.io

This tutorial demonstrates how to create and run a simple JPA application. The demonstrated application uses JPA to store and retrieve simple  Point entity objects, where each  Point has two persistent fields -  x and  y . If you already know JPA - the source code will be straightforward

replace the content of the new source file with the following code : package guest; import java.util

well (dialog boxes and menus might look slightly different but the code would be the same). Note

of the new source file with the following code : package guest; import java.io.IOException; import javax

Throws: EntityExistsException - if the given entity is detached (if the entity is detached, the {@ code EntityExistsException} may be thrown when the persist operation is invoked, or the {@ code EntityExistsException} or another {@ code PersistenceException} may be thrown at flush or commit time
