Making a Many to Many CMR in Netbeans

Anyone have any clue how to do this?
I have the classic three tables:
create table user (
id integer,
name varchar(30)
create table role (
id integer,
name varchar(30)
create table userrole (
userid integer,
roleid integer
I use NB 5 to create the User and Role beans from the Database. Then I go in to the ejb-jar.xml visual editor, create a CMR that's Many to Many, UserBean to RoleBean, create a CMR field in UserBean names roles. I leave "create CMR field" for RoleBean unchecked.
Then I go to sun-cmp-mappings.xml and open up its editor.
Click on UserBean, see the CMP fields all mapped. On the roles field, I click the Mapped Column drop down box and select "map relationship field". This pops up a new wizard, but I can't get Next to light up, and there's nothing in the Related Bean column of fields, and they're disabled so I can not change them.
So, I'm kind of stuck at this point and curious if someone can step me through creating this relationship.

With Netbeans 5.5 that's very easy, if you do not encounter bugs (it is a preview release):
Just anotate your beans :
class User {
@ManyToMany(mappedBy="members")
public Collection<Role> getRoles(){
class User {
@ManyToMany
public Collection<User> getMembers(){
Then the application server will create the tables for you

Many-to-Many CMR

hi all,
i defined two entity beans, Quiz and Question, with many-to-many cmr and
a table named Quiz_questions_Question_quizesTable is created in the database after deployment process. the formed table columns consist of primary key of Quiz and primary key of Question, as expected. what i want to do is adding one more column to this table that shows the sequence number of the related question in the related quiz. is it possible? and how? or what should i do?
thanks in advance..

"what i want to do is adding one more column to this table that shows the sequence number of the related question in the related quiz."
Makes sense, but then the association table is no longer just an association table.
Perhaps a way to get you in the right frame of mind is, "how would you model this with just objects?"
Basically a CMR just represents an association between two objects. You would see in your revised object model that you do not have a simple n-to-n association between a Quiz objects and a Question objects.[Quiz](0..n)---->(1..n)[Question]The above (bastardized UML) model does not represent the enumeration of Question objects within the scope of a single Quiz object.
Perhaps the following is more accurate:[Quiz](1)---->(1..n)[QuizQuestion](0..n)---->(1)[Question]or                     [Question]
                          A
                          |
                          |
[Quiz](1)---->(1..n)[QuizQuestion]It is only after you have your object model that you should worry about the entity bean stuff.

Prevent user from making to many requests...

Hallo everybody,
We are using Tomcat 5.0 and have some large jsp's (reports) that consume large memory.
1. Is there an easy way to prevent a user from making to many requests (eg. if he refreshes the page too many times, Tomcat gets an Out-of-memory error).
Of cource increasing the memory is not the answer I'm looking for (already did that).
2. Or may be a way to retrict a user to a certain maximum of memory
This seems like a common problem; anyone have good advice?
Thanks in advance.
Marcus

The main reason for multiple refreshes is the report taking too long to run and users getting impatient? Or is there another reason.
1 - Give the users fair warning. Put a message on the page saying "this report takes time to run. do NOT refresh this page as then the report will take even longer"
2 - You might set it up as a two stage process. Generate the report to a file. Then give them a link to check the progress of the report or load it if it is finished.
That way when they refresh, they don't regenerate the report, but just get back a immediate response that tells them "come back later"
3 - Perhaps you might consider the synchronizer token pattern.
http://www.javaworld.com/javaworld/javatips/jw-javatip136.html
4 - restricting users to max amount of memory would be difficult. How do you tell it is the same user? You could use a session variable, and record how many reports they have currently running, and reject any more then 3-4 requests at one time. But that could be worked around quite easily - just open up a new browser and its a new session.

Unidirectional one-to-many CMR in OC4J 9.0.3.1699

Hi,
I have the following issue with the new (productiv) OC4J 9.0.3 build 020927.1699, with did not occur with
build 020725.1695. I would like to deploy local entity beans CMRDepartment -1--n-> CMREmployee with container managed relations. Here's the relation part of ejb-jar.xml
<ejb-relation>
<ejb-relation-name>theEmployees2theDepartment</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>theEmployees</ejb-relationship-role-name>
<multiplicity>Many</multiplicity>
<relationship-role-source>
<ejb-name>CMREmployee</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>theDepartment</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source>
<ejb-name>CMRDepartment</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>theEmployees</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
</ejb-relation>
Now the problem is that the depoyment generates an database table CMREmployee_cmrtest_cmrtest for CMR with a foreign key column CMRDepartment_theEmployees referencing the CMRDepartment_cmrtest_cmrtest table for the CMRDepartment bean, even though the relation is not navigable from Emp to Dept. Is this a bug or a feature? Here's the CMREmployee part of the orion-ejb-jar.xml after deployment:
          <entity-deployment name="CMREmployee" location="CMREmployee" wrapper="CMREmployeeHome_EntityHomeWrapper27" local-wrapper="CMREmployeeLocalHome_EntityHomeWrapper16" table="CMREmployee_cmrtest_cmrtest" data-source="jdbc/OracleDS" exclusive-write-access="false" locking-mode="optimistic" update-changed-fields-only="true" delay-updates-until-commit="true" min-instances-per-pk="0" max-instances-per-pk="50" disable-wrapper-cache="true">

Trond,
when ou deploy your application, you should not need to include the orion-ejb-jar.xml.
Also, if you have previously deployed the application, delete the application directory UNDER both applicatopn-deployments and applications. The directory will be your application's name.
Hope this helps,

One-to-Many CMR problem

I am trying to get Container Managed Relationships working with Oracle Application Server. I am sure that the problem it quite obvious to anyone who has got this working before, but after carefully following numerous examples, I still cant get them to work. I have various issues including the application server blocking when it calls the getB() method in "A" to populate the items from table "B", even though the generated SQL looks okay e.g., "select B_PK from B where (b_fk = 1)".
I would be extremely grateful if you could point out my (hopefully obvious) mistake as I wrestled with it for the past couple of weeks.
Any ideas?
Cheers,
Jonathan
I have two tables A and B; A has a one-to-many relationship with B:
Table A:
     A_PK          (primary key)
     A_NAME
Table B:
     B_PK          (primary key)
     B_NAME
     B_FK          (foreign key to table A)

Ok, I found out something strange. If I do the addPet operation twice in the client the new relationship is created, too.
p = home.create("Violetta");
p.addNewPet("Jenny");
p = home.create("Frank");
p.addPet("Jenny");
p.addPet("Jenny");
May this be a timing problem? Or is there a command I could execute to ensure all data manipulation is populated to the DB. (Like close() in JDBC)
TIA

Is ios7 really in the making? Many posts show its true.

I need to know if its true. If ios 7 of APPLE has the features shown in internet. If theyre true or not. Thanks :)

Would be logical to assume that when new IOS comes out it is not going to be 8.
Would be logical to assume that at some point it is not going to be 6 anymore.
Don't I wish to know something else, would not be typing here if I did thou.

Many to many relationship does not work on certain role played dimension

Hi,
I have a cube with role playing Account dimension, used once as “Account” and once as “Other Account” dimension.
I’ve added Trip dimension related to the account dimension by a bridge table AccountTrip
making a many to many relationship (many accounts can be in one trip and one account can go to many trips).
When I added the bridge measure group to the cube, I saw in the dimension usage tab that the relationship between the bridge and the Account dimension was done automatically.
I added the trip dimension with regular relationship to the bridge measure group and many to many relationship to the main fact table using the bridge group.
All compiled fine and gave correct results. Then I noticed that when slicing the fact table by the Other account dimension I get correct results,
but when I add the Trip dimension I get the results as if I was slicing by the Account dimension, not by the “Other account” dimension.
I checked the cube and noticed I did not set the relationship between the bridge to the “Other Account” dimension (role playing). I set it now (regular relationship, same as the account dimension), but still getting the same results.
Conclusion- when slicing by the new Trip (M2M) dimension and the “Other Account”
(role played) dimension I get the results of the “Account” dimension, not those of the “Other Account” dimension.
I checked the relationships of the “Other Account” dimension in the cube but it looks correctly set (to the external account of the main fact table and to account of the bridge table).
(Just to note I have two other bridges on the cube which are not related and don’t look like they need to be related, plus two other measure groups of the main fact table used for distinct count which are related appropriately).
What else should be done???
I would greatly appreciate your help!
Thanks

My Iphone is disabled because of too many attempts at unlocking in with incorrect passcode. I know the code and do not want to "restore" phone. How can I fix this

My Iphone 4 is disabled as a result of someone making too many attempts at guessing my passcode. I know my passcode and do NOT want to "restore" my phone. Is there a way for me to use my passcode to unlock it once it has been disabled?

Its frustrating because all of the help assumes you have forgotten your passcode, or that you can get in to your phone to get the ID number.

Ejbgen: bug in many-to-many cmp

Well, I created a new Apple ID and I put money on it, I wanted to sign into ICloud and it wouldn't let me sign in due to the usage of too many Apple IDs created. The point for logging into the ICloud was to save my photos before I reset my phone.

I recently created a new apple ID
Bad idea.
Content bought with an Apple ID is forever associated with that Apple ID. Apple will not transfer content from one Apple ID to another and Apple will not merge Apple IDs. Unless you are prepared to forfeit all the previously purchased content and buy it all again with the new Apple ID, you will need to maintain the old ID to update and redownload your content.

Problem Removing CMP 2.0 Bean from Many side of One-to-Many

I'm getting an exception within the weblogic container when I try to
delete a bean from the many side of a one-to-many CMR.
The two entity beans are called CaseFile and CaseExpert. There are
many CaseExperts for each CaseFile. When you call the remove method
on the CaseExpert, Weblogic throws a null pointer exception when
accessing the EntityCache as shown at the bottom of this message. I'm
using the latest version of Weblogic 7 (WebLogic Server 7.0 Thu Jun
20 11:47:11 PDT 2002 190955). My relationship section of my
ejb-jar.xml file is also shown below.
Any ideas?

Hi,
I like to do the following:
1) Map one bean corresponding to table A to many beans corresponding totable
B 2) table B has two columns as the primary keys.
3) One of the primary key column in table B is a foreign key pointing tothe primary
key of table A.
4) bean corresponding to table A has the cmr Collection field
I am not able to map this scenario. I guess the mapping is possible aslong as
each table has its own unrelated primary keys. If anyone has tried this,please...please...help.

One-to many relationship in EJB

hi forum
wish you a very happy and prosperous new year
i want to implement CMR in my project but to start with i tried sample application setting one-to many CMR between EMP and DEPT table of scott/tiger .the problem is i have to modify my orion-ejb-jar.xml how can we do it?

Are you using JDeveloper? JDeveloper automatically creates the orion-ejb-jar.xml file when you use the EJB wizard.

Changes that Verizon is making

I have been a verizon customer for years and before they made this data package change I was enrolled in the unlimited data usuage. Now I need to get a new phone and they said that I have to go into the 2gb or 4gb data usage. Thats a shame if you are enrolled in something they should be bound to what you originally enrolled into. I would understand if I quit using the data service to go to a basic phone then switched back but I did not.Verizon is making to many changes to their company and they will lose a lot of their customers if they dont stop. I am hoping another company comes in and gives better opinions. They told me they have to stop the unlimited data usuage because to many people are on the internet.

I hear you.
Every time I go to the gas station it seems I am paying more and they are offering me "less". Same at the grocery store. It seems I am continually paying "more" and coming home with "less". When will these companies learn that I have been coming to them for years and don't deserve to have my prices go up?
Of course sometimes they artificially lower the price of something in the store just to bring me in, but these "loss leaders" don't offset the continually rising prices of the rest of their products! They need to stop now. It would be different if I was to go and buy different food with different properties, but I want the exact same food with no extra features than the food I have purchased in the past. Yet the price is still more!
You would think with all the technology advances and the fact they can make more food at a lower cost, my food bill would be dropping, but it isn't!

JavaFX and NetBeans Integration Request

How about it team? Please integrate SB into the next release of NetBeans (7.4.1).
Yes, I have seen the pages at: Using JavaFX Scene Builder with Java IDEs: Using Scene Builder with NetBeans IDE | JavaFX 2 Tutorials and Documentation
OK so I am able to call SB from inside the NetBeans 7.4 IDE. This is not integration. Its a shortcut. I mean, why do we have two separate tools? NetBeans IDE and SceneBuilder. We don't pop open SQLDeveloper when we work on queries, so why pop open SB?
Integration would be that the capabilities of the SceneBuilder would be available IN the IDE such as they are for Swing or for databases. Integration means you would have the palette available with the JavaFx components. It would be the current version of SB. ( When SB2 comes out, it would have all the functionality of SB2 )
From reading the scant information out there, SB2 is in development, why not integrate it into the IDE and make it one spot to do your development? Take JavaFx mainstream and integrate it into the IDE for real.

The Scene Builder team is working to create a product that integrates well with many IDEs, and NetBeans is one of them. As you might have heard from the last JavaOne, we are working on an API, called Scene Builder Kit, which will allow the integration of Scene Builder panels and functionality directly into the GUI of an IDE.
Based on this, we hope to collaborate with the NetBeans team -- and with teams from other IDEs -- to provide as tight an integration as we can, but ultimately this is a partnership which requires work from both the IDEs and SB teams.
As crucial as we see a tight IDE integration for our users' productivity, we feel that a SB standalone tool is also needed for those of our users who do not wish to use an IDE because, e.g., they focus solely on the layout and styling of a GUI.
Thanks for your feedback, please keep it coming, this helps us.

Netbeans .properties problem

Hi, like many users on this forum i see i am having a problem with Netbeans 6.8 and .properties files. All the solutions i have seen posted on this forum and others don't work when i try them i have the culprit file in the Source packages category and i have tried placing it in many categories in Netbeans and directories on my windows 7 computer and have no luck here is the code i have for this
public static InputStream in;
public static String servername;
public static Connection con = null;
public static String fullname1;
public String setserver(){
servername = server_entry.getText();
String servername2 = servername;
try {
Properties prop = new Properties();
in.getClass().getResourceAsStream("servernames.properties");
prop.load(in);
prop.put("database",servername2);
in.close();
any help would be appreciated and if you don't want to help or are going to say "figure it out your self" or "do a search someone already found a fix" Don't i searched high and low and found nothing that worked, thanks

Having never had the problem you express nor seen before in the years I've been on the forum, all I can tell you is the general procedure I go through when I suspect an install problem, and I would definetely suspect an install problem in your case:
1 - check your logs to see if there are any needed services that are not starting and resolve the problems to enable their loading
2 - uninstall your software (IDE and Java)
3 - delete the root folder of each
4 - edit my environment variables to remove any mention of it or prior versions in my path
5 - edit my environment variables remove my classpath entry alltogether.
6 - run a regitry cleaner like CCleaner until no registry errors persist. you'll probably need to run this multiple times.
(this is not an endorsement for that free product, but I do use it and it does work and it is free.)
7 - reboot (cold boot)
8 - download fresh copies of the software (IDE and Java)
9 - install Java
10 - reboot
11 - install IDE
12 - reboot
13 - check path environment variable and make any nessisary changes
14 - check path environment variable and make any nessisary changes
I have to think your system is messed up some place and your install did not complete or register correctly.
