Install GWT, Spring, Hibernate, JBOSS

I am new to Java.
I am going to create a web application using Java, I was told I have to install GWT, Spring, Hibernate, JBOSS, JDK 6 and mySQL.
I already install mySQL and JDK 6. Do I need to install Eclipse also?
what's the pupose to install GWT, Spring, Hibernate, JBOSS? what's the relationship of them? is there any order to install them?
Thanks very much.

Then they should be prepared to provide some help with your start.
Don't say no to me, I want to give it a try.Ok, I won't say no. I will still say you'll have a hard time. Be ready to learn a lot.

A beginner to design pattern(Struct,Spring & Hibernate framework)

Actually I am beginner to MVC2 Approach of complex application incorporated by design pattern as Struct,Spring & Hibernate framework.
Currently I am learning JSP Concepts,I have one doubt.
(1)What are the things I should grasp even before taking off to Design pattern?
Help me anyone plz?

You should know JSPs using JSTL without scriptlets.
You should understand relational databases and SQL.
You should understand HTML and HTTP.
Personally I think Struts, Spring, and Hibernate all at once are well beyond any beginner.
It's hard to advise you on what to do without knowing your capabilities and the problem you're trying to solve, but I think you should try it first using just JSPs, servlets, and JDBC. Get that to work and then refactor it to use the frameworks. You'll understand and appreciate them more that way.

Spring/Hibernate tier called from Java Stored Procedure

Here is my scenario.
Building out a new physical model alongside an old db.
Two schema's inside same Oracle instance.
We are building a new Java tier on top of the new schema using spring/hibernate.
To maintain sync with the old db we are building a load of PLSQL code that will be called by PLSQL stored procs on the old schema.
====
Now it occurred to me that if I could put a copy of my new java tier in the database itself then the trigger code on the old schema could call a java stored proc wrapper which in turn called into my new java tier inside the instance.
This way I avoid duplication business logic in the db sync and the java middle tier. Basically I do away with the PLSQL sync code and just use the new java component.
This clearly has advantages from an automated testing point of view too.
So very interested in how/if anyone has made this work.
Potential issues...
- JVM version (outside the db we use Sun Java 5 - inside the db I'm not sure what is used).
- How would spring access it's config files?

user563578,
You asked:

You also asked:
Potential issues...
- JVM version (outside db use Sun Java 5 - inside db not sure)
- How would spring access it's config files?
Oracle has its own JVM embedded in the database: OJVM
In Oracle 8i it is compatible with JDK 1.2
In Oracle 9i it is comaptible with JDK 1.3
In Oracle 10g it is compatible with JDK 1.4
You can access files outside of the database from OJVM, you just need to set correct permissions.
Perhaps Kuassi Mensah's book, Oracle Database Programming Using Java and Web Services will be of help?
Good Luck,

And now running into this exception

I am not using ADF in my project , is there any configurations I can change to get this working
Thank you for your time

Check that your project properties->libraries don't contain ADF, and also check the web.xml file of your project to ensure no ADF enties in there.

IPlanet Compatibility with Spring/Hibernate

Hi,
I need to develop a J2EE application.
I need to used iPlanet as a Web Server.
I want to know the compatibility if iPlanet with Spring/Hibernate.
Is it possible to develop an application using Spring/Hibernate if iPlanet is the Web Server.
thanks

Do you mean iPlanet Web Server 6.0? That's more than 7 years old. It's no longer supported by Sun and contains unfixed security vulnerabilities that make it unfit for production use. Modern versions of Spring and Hibernate won't work with the ancient version of the Java Servlet specification implemented by Web Server 6.0.
Spring and Hibernate will, however, work with the current iteration of Sun's web server product, Sun Java System Web Server 7.0.

FDS+Spring+Hibernate

If any body has worked with FDS /Hibernate/Spring
pls post the sample.
regards
anil

The posts here that point to examples of Spring + FDS and
separate examples of Hibernate + FDS and then say combining the two
should be easy seem to be missing the point. This is not as easy an
straight forward as it seems it should be.
Spring + Hibernate + FDS is a completely different animal
because you are getting Spring to handle the Session Factory
configuration and your DAO's as Spring beans but you also want the
handling of lazy initialization and proxy serialization as shown in
the HibernateAssembler.
The current HibernateAssembler code handles all of the
Hibernate setup. I would much rather have Spring do this. What I
would like is for my HibernateProxy's for non initialized
associations to be serialized rather than traversed resulting
LazyInitializationExceptions. The HibernateAssembler seems to
tackle this with a very mysterious piece of code:
PropertyProxyRegistry.getRegistry().register(HibernateProxy.class,
new HibernatePropertyProxy());
PropertyProxyRegistry and HibernatePropertyProxy are not
documented anywhere, and in fact a Google on PropertyProxyRegistry
returns 0 results. However, my intuition tells me this piece of
code should tell serialization to proxy the HibernateProxy with a
flex class called HibernatePropertyProxy which will just serialize
an id of an association rather than attempting to serialize the
uninitialized associated class.
I cannot get this to work though and as there is no
documentation and no discussion on these classes, I have no way of
verifying it. If my intuition is correct, this is a very useful
mechanism. I only wish it was documented b/c if it did work as
expected it would make a Hibernate + Spring + FDS implementation
pretty easy.
Anyone know anything about this?

J2EE(Spring/Hibernate) application migration to ADF

Hi,
Is there any migration method to migrate J2EE(Spring/Hibernate) based application to ADF based applicaiton?
Thanks

Kind of depends on what you are looking to to use from the ADF stack.
One option is to just build an ADF Faces UI on top of your existing backend (You'll just need to bring the Spring and Hibernate classes into JDeveloper).
You should be able to also expose your Spring facades as ADF Data controls and use ADF Binding on top of them.
Seems like this is what this guy did: http://blogs.oracle.com/michaellee/2009/08/creating_a_spring_adf_library.html

Anyone sucessfull to install LC ES on jboss/linux?

Hi i tried to install this on debian, jboss 4.2.0 (manual config) 4.2.1-bam(preconfigured) using alternativly jdk 5 and 6 with these guides:
http://help.adobe.com/en_US/livecycle/es/prepareinstall.pdf
http://help.adobe.com/en_US/livecycle/es/install_jboss.pdf
first with the linux installer which trows just errors and does nothing, then with windows installer targeting linux/jboss.
i get a heap of errors when starting Jboss after aplying the changes stated in the instalation manuals.
my questions:
what were your experiences to install this on linux?
was the provided guide satisfying?
is there some alternative installation guide?
E

Among the myriad Linux flavours out there, LiveCycle ES2 is supported only on Red Hat Enterprise Linux and Novell SUSE Enterprise Linux. We have several successful deployments on those.

Spring hibernate JSF 2.0 Application

I am trying to deploy application developed using this tutorial http://www.myeclipseide.com/documentation/quickstarts/ME4STutorialScaffoldingJSF/scaffoldingjsfarticle.html to weblogic server and running into all kinds of problem with configuration issues with hiberante properties and persistence.xml files , i was wondering if anybody has links to tutorial or sample project using spring / jsf 2.0 and hibernate developed in jdeveloper
the sample application works fine in tomcat , not sure how to configure this to weblogic server . trying to rebuild the app in jdeveloper and having problems deploying . my latest error is
Caused By: org.hibernate.HibernateException: The chosen transaction strategy requires access to the JTA TransactionManager
if somebody can help me with configurion parameters to connect weblogic server instalation ( ideally to the integratedweblogic server started from jdeveloper) from myeclipseide , that would help as well

Java Studio Creator -- web service -- spring -- hibernate -- database

Hello,
Has somebody already worked on an architecture 3 tier including : hibernate, spring, a deployment of the classes "spring" in wsdl (Web service).
With Tomcat and Axis i deploy some web services (classes --> wsdl), with java studio creator i call the web service and the methods ...
I would know if it possible to deploy some "spring" classes to have finally (wsdl) ?
Thanks

Heh heh heh....welcome to the club.
There are <b>many</b> of us wanting to integrate Spring with JSC.
I am working on doing this now, and plan to submit a quick tutorial on the subject to this forum once (if) I get it working.
To start you off in the right direction though, here are some things I <b>think</b> you need to do.
1) Make JSC Spring aware by adding the Spring.jar file in the Project Navigator (right click...Create New Library Reference).
2) Add the package structure you need in Project Manager
3) Add you Spring configuration file (application-context) in web/WEB-INF
4) Add your ContextLoaderListener to web.xml.
5) Get a servlet context and use it to get a WebApplicationContext
6) Use that to retrieve the bean you need to work with

Joined subclasses, JAXB, Hibernate, JBOSS

Hi All !
sorry for my english
I use JAXB and Hibernate ver. 2.0
I get classes, mapping, sql schema, sources from xsd files.
Why on generating mapping files with Ant (1.6.2) i get derived class mappings in those base class mapping? i want to get separeted mappings for each of all derived classes.
I need this feature couse i use this files in my JBOSS which dont like monolithic files.

I log on the application , i update this list outside the application ( by using sql command) , i try to list my data using the application : the application does not reflect the modifications. I logout using the log out link, then i log on and the application does not reflect the modifications. what happens? How could I resove these problems. How can i logout properly? how can i show logout link when the user is logged in? and hide the log out link when the user is logout Thanks.

For the first problem, you need to realize that the accountBean always exists since you configured it in the faces-config.xml. So you should use something else (like a property on the bean) to determine if the user has actually logged in.
Secondly, but still on the first issue, it is preferable to use the rendered attribute on the standard JSF components in this situation, instead of the JSTL tags.
Now, as to the second problem, there are a number of possibilities:
- did you commit the changes to the database?
- did you verify that another connection with the native db client can see the changes?
- are you using a cache with Hibernate? Are you taking the proper steps to notify the cache it might have stale data?
- are you keeping the list in session scope in your application? (Logging out doesn't clear the session unless you explicitly code it that way.)

Thanks.

It depends on how you want to reprecate the session btwn instances or cluters
there are three kinds File System, Memory to Memory, HA

You have two options wait for GWT to Update their plugin or Download Firefox 26
Firefox 26 - FTP
