DAO classes and Hibernate
hi all
need help.
i have one dought where is used DAO classes and where is
used Hibernate.i think both r used for data base access ,but why we are
used both.
thanks in advence.
i have one dought where is used DAO classes and where is
used Hibernate.Awesome, we got doubt misused AND misspelled!
i think both r used for data base accesscorrect!
but why we are used both.DAO is a design pattern (concept) and Hibernate is a product (code implementation).
Hibernate is a DAO implementation. That said, you don't need both, in fact you don't need either.

How to retrieve content from DAO Class and process in Controller Class?
Hello
This is for the experts.
What is the best approach to passing a large set of data from Class A to Class B? I have a DAO Class that connects to a database to retrieve data. I tried saving the data in a collection (map) and passing the collection to Class B. The problem here is that the data is may be too large for a collection without increasing the heap size, it could cause out of memory exception. Instead I'd like to pass the data (row by row) on to the "Controller" Class where which will process each row. I am not sure how to do this without using a collection or some sort. Some tips will be much appreciated.
Note: MVC Rules dictates that Controller cannot call the DAO Class directly, it has to go through the Model which talks directly with the DAO Class.
Thanks

Edited by: 875864 on 30-Oct-2011 15:05if its a large set of data, and is fetched from DB and you are sure that it is too large and chances of getting out of memory exception then why you are passing it over request.
If the data is fetched based on some filter criteria, then just pass the filter criteria from class A to class B, and fetch the data from DB based on the filter criteria in class B. -
Where clause and order by to DAO classes
Hi
Is it ok(I mean design wise) to pass the 'where clause' conditions and order by clause as a parameter to the method of DAO class?Well, I would suggest you write seperate methods in your dao , one to select data without the where clause and one to select data with the where clause thrown in. If you have different 'where' clauses for selecting different kinds of data, have that many dao methods. The dao methods being specific know exactly what is the data that's coming in.
Lets assume you have a list of purchase orders and each purchase order is indetified by a unique id called PURCHASE_ORDER_ID.
1. The following code would populate a purchase order's details given an id.
private statis final String QUERY_1 = "select * from PURCHASE_ORDERS where PURCHASE_ORDER_ID = ? ";
PurchaseOrderModel getPurchaseOrderData(long poId){
//get a prepared statement from your connection
PreparedStatement pst = conn.prepareStatement(QUERY_1);
//set the poId passed as params to your query
pst.setLong(1, poId);
ResultSet rs = pst.executeQuery();
if(rs.next()){
//populate data into a model
finally{
//clean up resources
return model;
}2. The following code would return a list of PurchaseOrderModel's whose shipping date falls between a set of dates selected by the user.
private statis final String QUERY_2 = "select * from PURCHASE_ORDERS where SHIPPING_DATE between ? and ? ";
PurchaseOrderModel getPurchaseOrdersBetweenDates(list bindValues){
//get a prepared statement from your connection
PreparedStatement pst = conn.prepareStatement(QUERY_1);
//set the dates passed as params to your query
//we know that the List ought to contain only 2 dates
pst.setDate(1, (Date)bindValues.get(0));
pst.setDate(2, (Date)bindValues.get(1));
ResultSet rs = pst.executeQuery();
if(rs.next()){
//iterate and populate data into a model
//add model to a list
finally{
//clean up resources
return list;
3. This is more interesting - the dao method searches a list of Purchase Orders starting with a set of specific words. The words themselves may be one or many. This means that the number of '?' in your prepared statement may be dynamic. Each element of the list is a String that contains the start substring of a purcahse order name. For example - the list may contain elements like ["a", "ab", "c", "gh"] and the dao method returns all purchase order starting with these names.
private statis final String QUERY_3 = "select * from PURCHASE_ORDERS where ";
PurchaseOrderModel getPurchaseOrderNameMatches(list bindValues){
//construct the query dynamically
StringBuffer query = new StringBuffer(QUERY_3);
int count = 0;
for(Iterator itr = bindValues.iterator(); itr.hasNext();;){
String value = (String)itr.next();
query.append ("name like 'value%' ");
if (count != 0 and (count+1 != bindValues.length)){
query.append(" or ");
count ++;
//get a prepared statement from your connection
PreparedStatement pst = conn.prepareStatement(query.toString());
ResultSet rs = pst.executeQuery();
if(rs.next()){
//iterate and populate data into a model
//add model to a list
finally{
//clean up resources
return list;
To sum up,
1. You need as many methods as you have different kinds of searches (one method for each kind of 'where' clause).
2. The ejb/business layer would examine the data and decide on which method to call.
3. Increases coding effort, but makes the code clean and readable. Each layer does it's job. Thus we dont have ejbs forming 'where' clauses and so on.
Having said that, it really is your decision - you should take into consideration the following factors -
1. How big is the project ? If its a huge codebase developed by many people, then segregate the responsibilities clearly in each layer as I have outlined. For a small scale project, you could go with your approach.
2. Whats the take on maintenance and future add-ons ? Do you see the codebase growing with time ?
3. Is your project a commercial one - is it a product that needs to be maintained or is it a one-off development - develop once and you are done with it.
4. What are the design considerations ? Is somebody going to audit code for quality ? Or is it a academic one ?
You should take into account all these before deciding to go one way or the other.
A general thumb rule should be that you should be convinced that your code readable (maintainable), scalable and efficient. Anything that you do towards these ends is good code/design despite what people/books/patterns say, IMO.

Transfer Object in JSF, Spring, and Hibernate
The application on which I am working deploys the JavaServer Faces, Spring and Hibernate frameworks.
We are going to use the "transfer object" to move data between J2EE tiers from the front end to the back end and vice versa. In addition, data "types" may need to be converted --
At the front end, the "type" of the data that are entered by users may not match that in the database table. For example, checkboxes may be marked or left blank by users. The "type" of the checkboxes is "boolean" in the JSF backing bean. However, we have either "Y" or "N" for the corresponding field in the database table.
The JSF backing bean holds data as well as controller functionality. Of course, the transfer object holds data only.
With regard to class properties, Is the transfer object an exact copy of the JSF backing bean? And at which tier the data are converted to match their correspoding "types" in the database tables?
We also have the "data objects" which are exact representation of database tables.
Thanks for your advices.Small example: you can decide in the business layer
whether to convert it to boolean or Boolean (which
has a 3rd state: null).But it all goes back to your data model. If your data model supports null for that property, then of course boolean is a poor choice. If that case one could use Boolean. None of this has anything to do with re-usability, which was your objection.
I think the re-usability question goes back to the data model as well. Suppose your data model says this property is boolean valued. However if your database does not support booleans natively, then you need to map the value for storage in the database. But that is the data persistence layers problem.
OTOH, suppose your data model says that this property may be 'Y' or 'N'. Then the Java class represent the business object should not have a boolean property, we should make it match the data model.
However, I think that most cases where people are storing 'Y' or 'N' in a field in the database fall into the first case, where the data model is a boolean and they are working around limitations in the database. There is no reason in that case to perpetuate the same limitations in the Java code. -
OC4J 10.1.3.2, JPA and Hibernate 3.2 Exception on Deployment
I can't get my simple web application to deploy in my standalone oc4j container. The European organization that I working for wants to use the new technologies out there. Part of the testing is getting oc4j working with hibernate. My web application works just fine with Toplink, but not with Hibernate3. The same web application in Tomcat works for both. The error that oc4j generates is shown below and really doesn't say much that I can do. I followed this blog instructions.

Parent Child Hierarchy with FDS and Hibernate
I know my chances of getting heard here are slim, but I am at
a dead end, so here goes.
I have a four level hierarchy of objects
PlanPoint
....UserScenario
........Scenario
............Competitor
which have bi-directional one-to-many relationships between
them.
I have made sure that my hibernate mappings and FDS
destination are matched and I definitely need to have managed
associations as the graph of objects will grow large in my
application (and besides, it is good development practice). So I
have a fully formed project (or at least I think I do) and I get a
duplicate object error.
Right at the bottom I have an alternative that I have tried
which gives a different error.
Here is a snippet from my log... it picks up just after the
message arrives

I would provide my mappings and destinations but I can't fit
them in a messageHi,
thanks for the reply it was very helpful. I came to pretty
much the same conclusion and started on the path of a re-write of
the hibernate assembler myself. As far as I can tell the Hibernate
Assembler is a Java Assembler, so there didn't seem much difference
to me between fixing that one and writing another one. Adobe ship
the code.
Bit of a cheeky request, but I don't suppose you would be
willing to share your assembler layer so I have a template against
which to work? Biggest problem with this sort of activity is a lack
of examples which makes it very slow going and largely trial and
error.
If you would like to know more about our application I will
provide contact details so we can discuss.
Simon
PS Jeff Vroom posted a reply saying that the Adobe Hibernate
Assembler didn't work properly with hierarchical data (which I
imagine is every real application in the world), personally I think
Adobe should fix it or pull it.

Mapping data model to java classes and Interface.
Need help in mappning my data model into java classes;
Here are some of the details:
Table, Poll:
PollID int
PollName varchar
BusinessUnit varchar
DisplaySchemeID int // reference to DisplayScheme table.
Table, DisplayScheme
DisplaySchemeID
DisplaySchemeName
etc
Table, URL
UrlID
UrlName
UrlDesc
Table, PollURL
PollURLID
PollID
UrlID
PublishDate
etc
Table, Tag
TagID
TagName
PollID
So, a POLL is associate with a DisplayScheme.
A Poll can have many URLs and a URL can be associate with many Polls , mapped in the PollURL table.
and same is the situation with tags.
Essentially I want to learn how to do one to many mappning and many to many mapping.
Also to add, since I plan to use Ibatis for OR mapping.
So I should a Parameter call to map for creaint a Poll. And to create a poll the form submitted will have:
- PollName
- URLs ( multiple )
- one display scheme.
- Tags ( many )
So if you can show how to write a DAO createPoll method, then it would be great.
Not sure if am asking a lot, but this would be a great example to move forward.The below is the sample DAO Class.
For your case, you have to create your own PollBean with getters and setters and just pass the object to the method
public int create(Connection con, ProjectBean projectBean) throws SQLException {
int result = 0;
String insertQuery = " INSERT INTO" +
" M_PROJECT(" +
" PROJECT_ID," +
" PROJECT_NAME," +
" PROJECT_DESCRIPTION) " +
" VALUES(?,?,?,?)";
initPrepareStmt(con, insertQuery);
setString(projectBean.getProjectID());
setString(projectBean.getProjectName());
if(projectBean.getProjectDescription().equals("")){
setString(" ");
}else{
setString(projectBean.getProjectDescription());
result = executeUpdate();
return result;

Java6, tomcat6, ojdbc6.jar and hibernate 3.3
We were running an application with Oracle 10g, tomcat5 and java5 with ojdbc5.jar and hibernate 3 without any issues. We recently upgraded to java6, tomcat6, ojdbc6.jar and hibernate 3.3. We created a new instance of the Oracle10g database. We are now seeing intermittent errors at least once a week. The errors are:

The errors occur when the user is querying for a list of objects. It does not seem to matter which list or type of objects. Attempting to recreate the error has not been fruitful - the queries are typical and ordinary routine data pulls. In the forums we see a lot posts about compatibility between drivers. The oracle 10g is using the ojdbc14.jar in its lib. Do we need to update this? Can we run java 6 against the 10g instance reliably?
We have also seen a similiar issue occur once when the user tried a normal save:

It occurs mostly in my app too which uses oracle 10G with ojdbc14.jar , but client in weblogic 10.3 has ojdbc6.jar. My logic is , at that time network was impaired and oracle could not find exact cause of error. To replicate you can input severly in multiple threads same query to oracle so it cannot get timeout values or cannot serve incoming requests withing certain allowed timeframes. If you are using a RAC , it cannot SYNC those cache and memory dumps in GCS , PGA, and SGA, thus inconsistent state.

Integrate Crystal Reports with Spring MVC and Hibernate
Hi all,
having successfully used the JRC version 11.8.4.1094 in a Java environment with:
1)JBoss 4.2.3,
2)Oracle 11,
3)EJB 2,
4)Crystal Reports 2008,
I would like to integrate Crystal Reports into my existing spring MVC and hibernate web app using:
1)CRJ version 12.2.209,
2)JBoss 5.1,
3)Oracle 11,
4)EJB 3,
5)Crystal Reports 2008,

Have an idea, please?
Thank you.You'll need to install the Crystal .NET that comes with VS 2005. You then install Crystal XI R2 over the top and not only will Crystal be integrated with the IDE, it should use the updated assemblies from R2.

Add Image to Jasper Report with Struts 2 and Hibernate
Hi I want to add image to jasper report[pdf] in the environment of Struts 2 framework and hibernate. I am trying
this for last couple of days, but i am unable to get the work done. if any body know the steps to add image to
jasper reports, please help me or if u have any tutorials please let me know. I am using iReport-nb-3.5.0 to generate jasper files.
Thanks in advanceFinally i found a way to add image to jasper report. It is pretty simple, just give the exact image location to the image expression. In your web application, the image location may vary so, dynamically set the image location from your model class. Also, make sure that your lib folder contains itext-1.3.1.jar. If your lib folder contains itext-1.3.1.jar and iText-2.1.3.jar u will get like: java.lang.NoSuchMethodError: com.lowagie.text.Image.plainWidth()F
So remove the iText-2.1.3.jar and keep only itext-1.3.1.jar, try this will work -
Hi everyone,
I am trying to make a sample application for the evaluation
purpose. I have created some java beans and their corresponding
actionscript classes. When I call any java method which returns an
object say Student, it works fine. Flashgateway Servlet serializes
Objects correctly and no exception occurs.
But when try to do the same thing with Hibernate 3,
Flashgateway Servlet cannot serialize object and throws Hibernate
Lazy Initialization Exception.
Can any one guide me or show me some sample of Flex 1.5 and
Hibernate 3 .
OR
Help me to find what I am doing wrong .
Any help would be appreciated .
Thankshey flex 2 beta is come out.. people dont work much with flex
1.2 or flex 3,,, cause there is much difference in coding and
syntax. so i recommend u start using the new version,,flex 2 beta 3
, cause later it might cause problem.. -

Try following the JPA tutorials for WebLogic, JPA using EclipseLink or Hibernate will be the same if you stick to the specification. WebLogic 10.3.4.0 ships with a Java EE 6 compliant JPA 2.0 implementation in EclipseLink - you may want to give that a try.
http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial
http://wiki.eclipse.org/EclipseLink/Examples/Distributed
I also have a JBoss 6 tutorial for getting JPA working as well.
BTW, your persistence unit is currently application managed - try switching to container managed - then most of your jar dependencies will go away as everything is already setup for you to do dependency injection via the container.

thank you

Training material on JSF, Spring and Hibernate
Hi All,
I'm new to JSF. I need some good training material on JSF, Spring and Hibernate.
I've tried lot many tutorials online, but cannot find a real good one.
Also I need to learn how we can integrate together JSF, Spring and Hibernate to build web applications.
Thanks
PayalAs far as documentation vs examples, that depends on the individual.
The Spring documentation is quite large, but Spring itself is very modular. So you can pretty much get away with reading the pieces you need when you need them and ignoring the rest.
Start with inversion of control until you feel you understand the concept. At its core, the idea is simple. Suppose you have a business class, FooService, and it needs to utilize BarService to implement its business logic. The non-Spring way would be to have the FooService class be responsible for getting an instance of BarService. The Spring way is for FooService to have a setter to be given an instance of BarService:
public class FooServiceImpl implements FooService
private BarService barService;
public void setBarService(BarService barService) { this.barService = barService; }
}Then the Spring container is used to "wire together" the instances:
<beans>
<bean id="barService" class="BarServiceImpl" />
<bean id="fooService" class="FooServiceImpl">
<property name="barService" ref="barService" />
</bean>
</beans>Note the advantage when using the classes in different contexts, e.g. unit testing vs production.
If I were you, I would take the sample app you have already done with JSF and try to integrate Spring into it. Move all the business logic into beans in the Spring container while keeping the view logic in the JSF layer.

Why can't I play any of my playlists now?
