Tools for generating Entity Classes

Hi ,
I am new to EJB 3.0 Entity Beans .
I am finding it hard to develop a Entity Class .
Please let me know if there are there any Tools that will generate an ENtity class depending upon the database table ??

Hi!
Most IDEs like Netbeans and Eclipse can generate entities based on existing database schemas, but imho it's much more usefull to write the first few entities by yourself. It's a bit more difficult, but at least this way you will learn what each annotation does, where they can be placed and what attributes you can set on them.
Once you have a good general foundation you can skip this process by autogenerating these classes. But that's just my opinion.
Some examples:
Eclipse
Netbeans
Btw. there are no entity beans in EJB 3.0. These are plain old java classes, thus they are called simply entities to avoid confusion with the entity beans used in previous ejb versions.

XJC Tool - For building Java classes from Schema

Hi all,
I am using XJC tool for Building java classes from Schema.
Can we have any other tool for generating java classes from Schema?
Thanks in advance,
typurohit

Solved my own problem and forgot to post the answer: the "xsd:import" is also considered as a targetNamespace, so each xsd:import needs a package specified as well when using oracg. It would be helpful if the Oracle documentation had stated that, but it does not point this out.

Adf bc jar for base entity classes and extending them existing project

Hi,
I am using jdev 11.1.1.0 and have created a base workspace/project and adf jar for my base entity classes.
1. I can consume this base adf bc jar in a separate new consuming workspace and create VO based on base bc classes or create new EOs that extend base bc entity classes.
2. Furthermore, for an existing consuming project that earlier included src/ of base entity (BC components), i can remove the dependency on bc source and bring in this new adf jar and everything including the view controller and the service/datacontrol works fine.
The issue i am running into is as follows.
- In the existing project (#2) above i try to create a couple of entities based on entities in my base jar; associations are automatically brought in. Note i am not overriding any attributes. My intent here is to generate .java and implement some code.
- I then try to make my existing VOs based on the newly extended entity (VO overview->Entity Objects-> Shuttle NewEntity from Available to Selected)
- I then try to remove the old EO from selected under VO overview->Entity Objects->Shuttle OldEntity from Selected back
- I get a warning dialog box that says something to the effect that some viewlinks are dependent on these old EOs in this consuming project.
- I tried to laboriously analyzed dependencies and it this dialog box does not make any sense as I have already extended EOs and the tooling should be able to let me use these
My questions
- Why I am not able to remove old entities from VO dependencies
- Is it ok to leave the old EOs in "Selected" along with the newly extended EO ? What are the implications for this?
- I also thought about extending base associations, but did not go anywhere.
In general, I am ok with consuming an ADF BC jar that has entities etc. but not clear about removing dependencies of base EOs on VOs when entities are extended and consumed in a pre-existing project that used base entities.
I can send a project if any PM is willing to take a look at it.
Thanks,
ps:
I have already gone over the following info
http://technology.amis.nl/blog/215/organization-of-bc4j-domain-eo-and-business-vo-package
.. wants to create an enterprise data model in BC4J, reflecting the Enterprise Data Model set up in the RDBMS. All (or at least most) business rules will be implemented in the Middle Tier – to take the load of the database and also allow developers not comfortable with PL/SQL to define and maintain the business rules. It is clear that this means that all applications that need to access – and manipulate – the database, need to go through the BC4J foundation layer. Martijn wants to define the Entity Objects – and their business rules – only once and share that definition between different projects. Each projects can create its own ViewObjects on top of these shared Enterprise Entity Objects.
http://radio-weblogs.com/0118231/2005/09/29.html
I am currently working on a project for a partner where we will be using ADF BC as our model layer for a large application. In order to keep the footprint of each application module down to a reasonable size, we are intending to create a number of separate 'root' application modules for each functional area of the application. Within, these 'root' application modules we will then use nested application modules to further partition the application. All of the application modules will be accessing the same datasource and will need access to the same database objects.
In order to separate our code between the development team and into function areas, our initial thoughts were that we would create an ADF BC model project containing Entity Objects for all of the database tables e.t.c. as these are common amongst all functional areas. We have configured all of the EOs for validation rules, defaulting values and extending doDML() as appropriate. Happy at this stage we then created a simple .jar file to deploy all of the definitions. Upon creating a new ADF BC project for each functional area we added the jar file as a library import into the new project. However when we the tried to create some new View Objects via the JDev Wizard we were unable to see the imported Entity Objects.
Is the only way to share Entity Object definitions between different ADF BC projects to manually copy the source definition files into the new projects src directory? Since this would mean multiple copies of the same components, it could prove to be a maintenance nightmare.Is there a way of doing it without creating multiple copies of the same object definitions?
The developer is spot on in their ideas of layering and reuse, and even has created a library for their reusable entities. This last step is not something everyone thinks to do. The missing step is known as "importing" components, so with that one extra bit of knowledge under his belt, he should be able to do exactly what he envisions. My little article called Difference Between Adding and Importing Business Components tries to explain the difference and gives the menu options to choose to perform the importing.

Hi,
since you followed the OC4J developer guide I think this question might be better handled there as well

ToString() and Comparable T on a JAXB generated entity class

Hello,
I'm trying to create a distributed system and therefore I have all my entity classes present in my Java EE app and hosted as a web service. The Swing frontend app autogenerate the entity classes for use in the presentation.
I'm having some trouble using the Collections.sort() since a generated entity cannot implement an interface, does anyone have a hint to how i can solve this issue?
Also, I need to override the toString() so that I can put an entity directly in a eg. JCombobox and it is presented with the return of my custom toString() but if I override the toString() in my original entity in my backend app, then this method is not generated in my frontend app.
Thanks in advance!

What is suitable method or Tool for Generate Reports or Inovice?

Which Tool or Class is suitable for Generate Reports or Inovice?
i hope to make some reports and invoice for my project,
but i don't know what is suitable class to generate and show report and invoice.
can you give me some advice?
thanks!

My report consists of one main repeating frame containing about 15 (detail) repeating frames. The main frame starts a new page each time the deposit (master record) changes and resets the physical page number at the top of the page. In the property palate, I have Source set to my deposit number and Maximum Records per Page set to 1 and this results in the start next deposit on a new page.
I can't find any 'BREAK' command that would result in the action I need - and there seems to be nothing in the SRW_package or conditional formatting that might help.
What I was hoping was that there would be a command somewhere that I have missed, that would cause a new report to be written each time the deposit (or master record) changes, rather than one huge report.
Thanks for the suggestion

Tools for generating java files

Hello!
I need a tool which can generate .java files (just like rmic generates _Stub.java files).
I know Velocity but i'm looking for something better. Can you help me?
Kuba Kr�likowski

rmic does not generate Stub and Skel .java
files, but it generates .class files.
(just a side-note)RMIC always produce .java files at first - you can keep them using -keep or -keepgenerated option!

Tools for generating weblogic-cmp-rdbms-jar.xml files

Hi All:
I am using Weblogic 8.1 sp6 and MyEclipse 5.1.
Does anybody knows if weblogic 8.1 provides a wizard or tool or some product that will help you generate the
weblogic-cmp-rdbms-jar.xml and webloigc-ejb-jar.xml files if given the ejb-jar.xml, the home, remote and bean classes and the database server information.
The reason, I am asking this is because if you're using Hibernate, there is a hibernate tool that will generate the hbm.xml and persistence classes given a particular database information.
I was wondering if there is the same thing in ejb development with weblogic 8.1 sp6?
Yours,
Desperate

I think u r some confusion with productID and SuppliedID . primary key of one column( productId ) can be a foreign key of other table colum( SuppliedID). but foreign key( SuppliedID) can not be a primary key of second table .u declared SuppliedId as primary key . so ur mapping is incorrect.

Tool for generating properties files

Hello Experties,
I am wondering is there a tool or program for SAP to get SAP fields screen names from SAP backend for diffrent languages and generat the properties files?
for java uwl or webdynpro they are all the same properties file.
thanks

WebDynpro i18n is done by .xlf files. Its an standard (http://en.wikipedia.org/wiki/Xliff) and there are some OSS editors available, just google xlf editor.Or check this one: http://okapi.opentag.com/applications.html#rainbow
The Idea is, that you give your xlf files to the translator and safe the results with a suffix representing the language (_de.xlf for german).
Hope this helps.

Tools for generating WSDL file

I have created one Java Web Service in Apache Soap. Now I want to create the WSDL file so that my clients will
come to know what is my Web Service about. But I am not able to find any tool which will automatically generate
the WSDL file from the Java Class since my Web Service is purely written in Java. I came to know about GLUE but
was not able to find the link from where I could download it. Can anybody help me to find such tools?

I dont want to use Axis. Even Glue has the same command to generate the WSDL file from Java. Do you have any
idea from where I could download Glue?

Any tools for converting java class to xml schema ?

Hi,
Are there any tools out there that can convert my java class to xml schema. How such tools take care of java collections like HashTable, ArrayList etc. in my class structure. I am not interested in writing any configuration files(like jaxb configuration files, jibx binding xml files etc.) for serving this purpose and the can be able to give me xml schema from the java classes. Please suggest ...
I am not sure even JAXB 2.0 allows me to do this without writing any jaxb configuration files or annotations in my java class which is not there in JDK 1.4.2
Thanks & Regards,
Kr.

Hi,
You can convert the EDI file to XML in any of the ways
1) Using third party seeburger adapters
2) Conversion agent
3) Stylus studio.
I think using java code it will be very difficult.
Thnx

Tools for Comparing Java Class Files

Are there any tools out there that can compare two .class files to see if they are the same ?? Please help.
Janet

In Windows there's the FC command that compares two files to see if they are identical. In Unix there is no doubt a similar command. Or you could write a small bit of Java code that reads the two class files and compares them byte by byte.

Generate ID classes using XDoclet

Hi,
Are there any plans to support the generation of ID classes via XDoclet?
Thanks,
Mike.

Are there any plans to support the generation of ID classes via XDoclet?Not currently. Note that we already provide an application identity tool
for generating identity classes. So you could use XDoclet to generate
the metadata and then the application identitity tool to generate the
identity class.
