Accessing model in other class

Hi all,
I have two classes, one is a JFrame and the the other one is a JDialog. In the JFrame, I have a JList that uses the DefaultListModel and an "Add" JButton. When the user clicks the Add button. The JDialog pops up and allows the user to enter the detail of a new entry for the JList. When the user click the "Save" JButton on the JDialog. The new entry is added to the JList. My problem is that I need to add the new entry to the DefaultListModel when they user click the "Save" button on the JDialog, but I have no idea how to access the DefaultListModel in the JFrame from the JDialog (in other words, to get the calling object reference).
I've searched the web for examples of using DefaultListModel, but the examples that I can find only use inner class. So there is no problem on accessing the DefaultListModel. But, in my case, I need to separate the two classes. Please give me some hints!
Thanks,
Welles

When you create the JList object, you can keep a reference to the ListModel and then pass it to the JDialog. Something like this:
DefaultListModel myModel = new DefaultListModel();
MyDialog myDialog = new MyDialog(myModel);Jimmy

How to access variables from other class

    public boolean inIn(Person p)
        if (name == p.name && natInsceNo == p.natInsceNo && dateOfBirth == p.dateOfBirth)
             return true;
        else
             return false;
    }//returns true if Person with same name/natInsceNo/dateOfBirth as phello,
here am trying to compare the existing object with another object.
could you please tell me how to access the variables of other class because i meet this error?
name cannot be resolved!
thank you!

public class Person
    protected String name;
    protected char gender;      //protected attributes are visible in the subclass
    protected int dateOfBirth;
    protected String address;
    protected String natInsceNo;
    protected String phoneNo;
    protected static int counter;//class variable
//Constractor Starts, (returns a new object, may set an object's initial state)
public Person(String nme,String addr, char sex, int howOld, String ins,String phone)
    dateOfBirth = howOld;
    gender = sex;
    name = nme;
    address = addr;
    natInsceNo = ins;
    phoneNo = phone;
    counter++;
public class Store
    //Declaration of variables
    private Person[] list;
    private int count;
    private int maxSize;
//constructor starts
    public Store(int max)
         list = new Person[max];//size array with parameters
         maxSize = max;
         count = 0;
    }//end of store
//constructor ends
//accessor starts
    public boolean inIn(Person p)
       return (name == p.name && address == p.address && natInsceNo == p.natInsceNo);
    }//returns true if Person with same name/natInsceNo/dateOfBirth as phope it helps now!

Loading XML using a custom class and accessing it from other classes?

I began with a class for a movie clip rollover function
FigureRollOver. It works marvellously. Three things happen:
1) it loads XML from a file "mod1_fig1.xml" and uses another
class, XMLMember, to retool the scoping of the XML so that I can
get at it
2) an onload call inside of XMLMember calls the myOnLoad
function and transfers the XML into an array.
3) so long as the array is finished building, rolling over a
movie clip attaches a new movie clip with the rollover text in it.
But I don't want all those functions in one because I need it
to be more dynamic, starting with being able to load any old xml
file instead of just "mod1_fig1.xml", plus it seems like
overbuilding to have all of that in one class, so I've separated
out the loading of the XML and building of the array into its own
class, FigureXMLLoader. FigureRollOver is then left to just attach
the rollover with text in it, extracted from the array built by the
new class.
Problem is, though the array builds inside FigureXMLLoader, I
can't figure out how to make it available outside the class. I know
that I'm constructing things in the wrong order, and that the array
needs to be somehow built inside the class function to be
available, but I can't figure out how to do that. A cruddy
work-around is to put a function call at the end of the building of
the array, which calls yet ANOTHER function on the main timeline of
my .swf to put the array I've just built into a new variable. This
works, but it's messy. It seems like I should be able to have one
line of script in the .swf that generates an array on the main
timeline (or just a public array) which I can then access from my
FigureRollOver class:
var myRollOvers:Array = new FigureXMLLoader("mod1_fig1.xml");
Here is FigureXMLLoader (see comments in the code for more
details) which obviously does not return an array as it is, because
of all the working around I've had to do. Note the "testing"
variable, which can be traced from the main timeline of the .swf,
but I will get "not what I want" because of course the array hasn't
been built yet, and never will be, inside of the declaration as it
is. How do I get it in there so I can return an array?
Thanks!

Suggest you ask this question in the Actionscript forum as
this forum is
more tuned to database integration questions.
You can create arrays outside a class and pass them into it
by reference and
visa versa build arrays inside a class and pass out via
reference.
The preferred approach is to place the array in a class and
not expose it.
Then add methods to use the array or should we say to use the
class.

Accessing string from other classes

Sorry if this seems simple to you, but i'm having problems accessing four string that are declared and used in my public class from another class.
I've tried declaring the strings public but it still says 'cannot resolve symbol' when i try to compile.
Help much appreciated.

Accessing arrays in other classes

do it.
Class1
Method1()
Fill OriginalArray[]
Class2
Method2()
If OriginalArray[0] = whatever //how can i access
s this array
}It depends. If the array is declared as public you'll be able to access it using the '.' notation:
public class One{
public Object[] a;
public One(){
    a = new Object[1];
    a[0] = new String("hi");
public class Two{
public void myMethod(){
    One one = new One();
    System.out.println(one.a[0].toString());
}Otherwise you'll need accessor methods, (get/set).

How to access variables from other classe through getter ?

Hi !
I have 10 classes
Cau_1.java containing char Cau_1_Answer;
Cau_2.java... Cau_2_Answer;
Cau_10.java... Cau_10_Answer;
and another class Resume_grammar.java with char[] AnswerList = new Char[10] used to hold cau_1_Answer, Cau_2_Answer...Cau_10_Answer.
but I don't success to get them.
In Cau_1.java, I do :
private static char Cau_1_Answer;
static char getCau_1_Answer() {
          return Cau_1_Answer;
     static void setCau_1_Answer(char cau_1_Answer) {
          Cau_1_Answer = cau_1_Answer;
if (a.isChecked()) {Cau_1_grammar.setCau_1_Answer('a');}
if (b.isChecked()) {Cau_1_grammar.setCau_1_Answer('b');}
if (c.isChecked()) {Cau_1_grammar.setCau_1_Answer('c');}
if (d.isChecked()) {Cau_1_grammar.setCau_1_Answer('d');}
Cau_2, Cau_3...are the same way.
in Resume_grammar.java :
     static char[] AnswerList = new char[10];
AnswerList[0] = Cau_1_grammar.getCau_1_Answer();
AnswerList[9] = Cau_10_grammar.getCau_10_Answer();
When I make AnswerList display, all is null (nothing displayed).
Please help ! What I do wrong ?
Thank you !

Private, protected Access Modifiers with a class

Why cant we use private and protected access modifiers with a class?
Thanks.

Public access allows you to extend a parent class in some other package. If you only want users to extend your class rather than instantiate it directly, make the class abstract and design for extension.Agreed. However, would the same argument be not true for the default access at the class level? No. Default access would only allow you to extend a parent class in the same package (as opposed to some other package).
Now my confusion is why is a class allowed default access at the top level and not protected?Because protected for a top-level class makes no sense. The protected keyword provides member access to any other class in the same package and extending classes outside the package. A top-level class isn't a member of a class, by definition, so there's nothing that protected would do provide differently than public.
So, the two access modifiers for a top-level class are public and default. Public allows access to the class outside the package, whereas default restricts access to the class within the package.

Weird classpath issue in EAR.Some classes can access jars that others cant!

Hi,
I'm experiencing a very frustrating problem that's proving to be a bit of a show stopper for me. I would really appreciate some help...
I have an EAR deployed successfully on Sun Appserver 8 which passes the tests from the sun EAR verifier tool. The ear contains a jar file that I built which has a stateless session bean, home, remote interfaces and rmi stubs, deployment descriptors, as well as some utility classes. The EAR also contains some third-party jars such as Hibernate, Log4-j, apache-commons etc etc. The jar I built has in it's manifest file, the classpath information to reference the other jars in the ear.
The problem I am having is that one of the classes in a third-party jar (hibernate3.jar) cannot see a class in another of the third party jars (log4j-1.2.8.jar) and as a result is throwing a NoClassDefFoundError for org/apache/log4j/Layout while trying to initialise - the two jars are at the root of the EAR.
Furthermore, my utility classes can access and use Log4j classes without any problem and logging command from those classes is output successfully to the server console. However, my session bean, which is packaged in the same jar as the utility classes, fails to log anything even though it uses exactly the same logger and log configuration as the utility classses.
I have tried adding classpath information to the manifest of the EAR so that the third-party jars can pick it up but this makes no difference. Also, according to the EAR verifier tool, you are not allowed to put any classpath information in the EAR manifest.
I have also tried deploying this in weblogic but am experiencing the same problem.
If anyone can offer any advice or solutions I would greatly appreciate it.
:)

whatÂ´s type error have you?
perhaps external libraries (located in classpath) invoke opsCommon.jar and config-3.0.jar classes. then, classnotfound is normal.
and... why separate external libraries (opsCommon.jar and config-3.0.jar inside ear, and other in classpath)?

Flash Vars is not working when we accessing from other class files

Hi all, I'm currently developing a flex application where i
need to pass the data from the flash vars to the other class files
instead of the main actionscript class file.
Does any body know how i should go about doing that?? you can
see this below code : please help me out if u know how to solve
testnew2.as file
package {
import flash.display.Sprite;
import flash.display.LoaderInfo;
public dynamic class testnew2 extends Sprite {
public var
xmlfile:String=String(root.loaderInfo.parameters.lists);
public function testnew ():void{
package {
import flash.text.TextField;
import flash.display.Sprite;
import flash.display.LoaderInfo;
public dynamic class testnew extends testnew2 {
public function testnew () {
var myText:TextField = new TextField();
// this assumes that you are going to pass in an id variable
// on the end of the myFile.swf?id=12345 or
// use FlashVars in the HTML parameter list for instance
// 'FlashVars', 'id=123456', 'width', '1024',
myText.text = new testnew2().xmlfile;
addChild(myText);
but if we access in same file it is working fine:
package {
import flash.text.TextField;
import flash.display.Sprite;
import flash.display.LoaderInfo;
public dynamic class testnew extends Sprite {
public function testnew () {
var myText:TextField = new TextField();
myText.text = String(root.loaderInfo.parameters.lists);
addChild(myText);

Pass the data into the main app, then from there either pass
it into the sub-components or use
Application.application.parameters, or bind to the values.

Hi All,
In the present ND project we have lots of utility classes. These

In these classes we access the dataobjects and do the

So we access dataobjects directly like
CSpider.getDataObject("do....");

Since the migration tool does not do much of conversion for these

My question is Can we access the the models in the post migration

We have lots of utility classes which are DataObject intensive.Can

Hi all,
if you add the following to your spider2jato.xml
It will automatically map your CSpDataObject.executeImmediate to use
ExecuteImmediateUtil.executeImmediateSelect with the arguments mapped as

Re: [iPlanet-JATO] Re: Use Of models in utility classes - Pease don't forget about the regular expression potential

Namburi,
When you said you used the Reg Exp tool, did you use it only as
preconfigured by the iMT migrate application wizard?
Because the default configuration of the regular expression tool will only
target the files in your ND project directories. If you wish to target
classes outside of the normal directory scope, you have to either modify the
"Source Directory" property OR create another instance of the regular
expression tool. See the "Tool" menu in the iMT to create additional tool
instances which can each be configured to target different sets of files
using different sets of rules.
Usually, I utilize 3 different sets of rules files on a given migration:
spider2jato.xml
these are the generic conversion rules (but includes the optimized rules for
ViewBean and Model based code, i.e. these rules do not utilize the
RequestManager since it is not needed for code running inside the ViewBean
or Model classes)
I run these rules against all files.
See the file download section of this forum for periodic updates to these
rules.
nonProjectFileRules.xml
these include rules that add the necessary
RequestManager.getRequestContext(). etc prefixes to many of the common
calls.
I run these rules against user module and any other classes that do not are
not ModuleServlet, ContainerView, or Model classes.
appXRules.xml
these rules include application specific changes that I discover while
working on the project. A common thing here is changing import statements
(since the migration tool moves ND project code into different jato
packaging structure, you sometime need to adjust imports in non-project
classes that previously imported ND project specific packages)
So you see, you are not limited to one set of rules at all. Just be careful
to keep track of your backups (the regexp tool provides several options in
its Expert Properties related to back up strategies).

Great response. By the way, the Regular Expression Tool uses thePerl5 RE
syntax as implemented by Apache OROMatcher. If you're doing lotsof these
sorts of migration changes manually, you should definitely buy theO'Reilly
book "Mastering Regular Expressions" and generate some rules toautomate the
conversion. Although they are definitely confusing at first,regular
expressions are fairly easy to understand with some documentation,and are
superbly effective at tackling this kind of migration task.

Also, (and Matt's document may mention this)
Please bear in mind that this statement is not totally correct:
Since the migration tool does not do much of conversion for
these
utilities we have to do manually.Remember, the iMT is a SUITE of tools. There is the extractiontool, and
the translation tool, and the regular expression tool, and severalother
smaller tools (like the jar and compilation tools). It is correctto state
that the extraction and translation tools only significantlyconvert the
primary ND project objects (the pages, the data objects, and theproject
classes). The extraction and translation tools do minimumtranslation of the
User Module objects (i.e. they repackage the user module classes inthe new
jato module packages). It is correct that for all other utilityclasses
which are not formally part of the ND project, the extraction and
translation tools do not perform any migration.
However, the regular expression tool can "migrate" any arbitrary
file
(utility classes etc) to the degree that the regular expressionrules
correlate to the code present in the arbitrary file. So first andforemost,
if you have alot of spider code in your non-project classes youshould
consider using the regular expression tool and if warranted adding
additional rules to reduce the amount of manual adjustments thatneed to be
made. I can stress this enough. We can even help you write theregular
expression rules if you simply identify the code pattern you wish to
convert. Just because there is not already a regular expressionrule to
match your need does not mean it can't be written. We have notnearly
exhausted the possibilities.
For example if you say, we need to convert
CSpider.getDataObject("X");
To
RequestManager.getRequestContext().getModelManager().getModel(XModel.class);
Maybe we or somebody else in the list can help write that regularexpression if it has not already been written. For instance in thelast
updated spider2jato.xml file there is already aCSpider.getCommonPage("X")
rule:

<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getPage[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getViewBean($1ViewBean.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
Following this example a getDataObject to getModel would look
like this:
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[CSpider[.\s]*getDataObject[\s]*\(\"([^"]*)\"]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[getModel($1Model.class]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
In fact, one migration developer already wrote that rule andsubmitted it
for inclusion in the basic set. I will post another upgrade to thebasic
regular expression rule set, look for a "file uploaded" posting.Also,
please consider contributing any additional generic rules that youhave
written for inclusion in the basic set.
Please not, that in some cases (Utility classes in particular)
the rule
application may be more effective as TWO sequention rules ratherthan one
monolithic rule. Again using the example above, it will convert
CSpider.getDataObject("Foo");
To
getModel(FooModel.class);
Now that is the most effective conversion for that code if that
code is in
a page or data object class file. But if that code is in a Utilityclass you
really want:
>
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
So to go from
getModel(FooModel.class);
To
RequestManager.getRequestContext().getModelManager().getModel(FooModel.class
You would apply a second rule AND you would ONLY run this rule
against
your utility classes so that you would not otherwise affect yourViewBean
and Model classes which are completely fine with the simplegetModel call.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getModel$]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getModel\(]]>
</mapping-rule-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getRequestContext().getModelManager().getModel(]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>
A similer rule can be applied to getSession and other CSpider APIcalls.
For instance here is the rule for converting getSession calls toleverage
the RequestManager.
<mapping-rule>
<mapping-rule-primarymatch>
<![CDATA[getSession\($\.]]>
</mapping-rule-primarymatch>
<mapping-rule-replacement>
<mapping-rule-match>
<![CDATA[getSession\.]]>

<mapping-rule-substitute>

Subject: RE: [iPlanet-JATO] Use Of models in utility classes
Namburi,
I will post a document to the group site this evening which has thedetails
on various tactics of migrating these type of utilities. Essentially, you
either need to convert these utilities to Models themselves or keep the
utilities as is and simply use the
RequestManager.getRequestContext.getModelManager().getModel()
to statically access Models.
For CSpSelect.executeImmediate() I have an example of custom helper method
as a replacement whicch uses JDBC results instead of CSpDBResult.

Subject: [iPlanet-JATO] Use Of models in utility classes
Hi All,
In the present ND project we have lots of utility classes. These
classes in diffrent directory. Not part of nd pages.
In these classes we access the dataobjects and do the manipulations.
So we access dataobjects directly like
CSpider.getDataObject("do....");
and then execute it.
Since the migration tool does not do much of conversion for these
utilities we have to do manually.
My question is Can we access the the models in the post migration
sameway or do we need requestContext?
We have lots of utility classes which are DataObject intensive. Can
someone suggest a better way to migrate this kind of code.
Thanks

Accessing httpsession in ApplicationModule class

is it possible to get a hold off httpsession in a class that extends ApplicationModuleImpl.
i can't seem to access FacesContext from this class. Where do i add the faces-impl.jar to, in order to get access to this api.
thanks

What are you trying to achieve?
It seems that you are trying to break the MVC architecture.
Your Model layer shouldn't be accessing your view/controller layer since then it looses its independence.
Instead the correct way to do what you are trying to do is write the code in the Controller layer. The controller layer has access to both the httpSession and the application module.
It can pass information from the http session to a service method of the application module.
For example:

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;
     }
