Use Of friend Class

In class builder what is the use of friend class and where can i find the standard classes and methods

Being someone's friend, means being allowed to use his protected attributes and method.
When you define a friend for a class, this class can addres these components as if they were public ones.
In real world: my friend (some class) can use my car (which is protected), which is not allowed to strangers (other classes).

How to use a protected attribute of class cl_gui_alv_grid

Hello all,
       i have a scenario where i need to use the attribute 'm_appl_events' which is protected attribute. in need to add this event type into my events and add this to registered events.
    when i tried to use this with refrence to class i defined, it showing an error message 'access to protected attribute m_appl_events is not allowed. i already inherieted the cl_gui_alv_grid class into my class
     can any one please tell me how exactly could i use the protected attribute.
Thanks,
raju N

Hi Krishna,
Protected method or attrubute can be accessed through Inheritence or Friends functionality. So you can inheritence easily in you case . so that you can access the variable in the Inherited sub class only. So you can write 2 methods ie GET or SET ing the value of your protected method.
I think this informatio may help you.

Can I no longer browse classes in interface builder?

in tiger, I used to be able to browse classes in interface builder, and from their I could create subclasses, and create actions and outlets. then I could create files for the classes from the classes menu. then when I went back to xcode I would have empty class file templates that I could then write the methods for.
also, I could easily instantiate my class via the classes menu.
alas, now I cannot find these features. have they dissappeared entirely? is there an equivilant way to do this?

I found that disturbing too...
However the system changed completely. You can no longer define the super-class directly in Interface Build, however you can still define classes there with IBOutlets and IBActions.
First, to instantiate a blue cube as a custom object, simply drag a blue cube from the Library windows inside : Library --> Cocoa --> Objects & Controllers --> Controllers.
To set the class, go in Identity inspector (CMD + 6) here you'll be able to define the class name, its outlets and its actions, you can even define the action argument type (sender) here, however, weirdly, they took the ability to add the colon directly at the of the method name, so you'll have to add it yourself.
However, Apple documentation advise you to add methods and outlets directly in Xcode and not in IB, "Whenever you want to create a new controller class, or add an outlet or action to an existing class, do it in Xcode."
Indeed, if IB is opened at the same time, it will update the class's outlets and actions directly, Xcode and IB are more binded together than before.

Using a variable from one class in another

For learning purposes, I thought I'd have a stab at making a role-playing RPG.
The first class I made was the Player class;
public class Player
 public static void main(String[] args)
 // [0] being base points and [1] being skill points
 int[] points = {50, 10};
 // Elements in statNames are relevent to stats, so stats[0] is health, and so on
 String[] statNames = {"Health", "Mana", "Attack", "Magic", "Craft"};
 int[] stats = new int[5];
 public static String setName()
 Scanner input = new Scanner(System.in);
 System.out.print("Character name: ");
 String name = input.nextLine();
 return name;
 public static void setHealth(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Health (" + points[0] + " base points remanining): ");
 stats[0] = input.nextInt();
 points[0] -= stats[0];
 public static void setMana(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Mana (" + points[0] + " base points remanining): ");
 stats[1] = input.nextInt();
 points[0] -= stats[1];
 public static void setAttack(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Attack (" + points[1] + " skill points remanining): ");
 stats[2] = input.nextInt();
 points[1] -= stats[2];
 public static void setMagic(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Magic (" + points[1] + " skill points remanining): ");
 stats[3] = input.nextInt();
 points[1] -= stats[3];
 public static void setCraft(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Craft (" + points[1] + " skill points remanining): ");
 stats[4] = input.nextInt();
 points[1] -= stats[4];
 public static void setStats(int[] points, int[] stats)
 setHealth(points, stats);
 setMana(points, stats);
 setAttack(points, stats);
 setMagic(points, stats);
 setCraft(points, stats);
 public static void charSummary(String name, String[] statNames, int[] stats)
 System.out.println("\n------ " + name);
 for(int index = 0; index < stats.length; index++)
 System.out.println(statNames[index] + ":\t" + stats[index]);
}And that would be used in the Play class;
public class Play
 public static void main(String[] args)
 Player player = new Player();
 String name = player.setName();
 player.setStats(points, stats);
 } But I'm not sure how the Play class will get the arrays from the Player class. I tried simply putting public in front of the them, for example;
public String[] statNames = {"Health", "Mana", "Attack", "Magic", "Craft"};But I get an illegal start of expression error.
I may have taken the wrong approach to this all together, I'm completely new, so feel free to suggest anything else. Sorry for any ambiguity.

HI XCD ,
what about making Player class as
public class Player
 // [0] being base points and [1] being skill points
 int[] points = {50, 10};
 // Elements in statNames are relevent to stats, so stats[0] is health, and so on
 public String[] statNames = {"Health", "Mana", "Attack", "Magic", "Craft"};
 int[] stats = new int[5];
 public String setName()
 Scanner input = new Scanner(System.in);
 System.out.print("Character name: ");
 String name = input.nextLine();
 return name;
 public void setHealth(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Health (" + points[0] + " base points remanining): ");
 stats[0] = input.nextInt();
 points[0] -= stats[0];
 public void setMana(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Mana (" + points[0] + " base points remanining): ");
 stats[1] = input.nextInt();
 points[0] -= stats[1];
 public void setAttack(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Attack (" + points[1] + " skill points remanining): ");
 stats[2] = input.nextInt();
 points[1] -= stats[2];
 public void setMagic(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Magic (" + points[1] + " skill points remanining): ");
 stats[3] = input.nextInt();
 points[1] -= stats[3];
 public void setCraft(int[] points, int[] stats)
 Scanner input = new Scanner(System.in);
 System.out.print("Craft (" + points[1] + " skill points remanining): ");
 stats[4] = input.nextInt();
 points[1] -= stats[4];
 public void setStats(int[] points, int[] stats)
 setHealth(points, stats);
 setMana(points, stats);
 setAttack(points, stats);
 setMagic(points, stats);
 setCraft(points, stats);
 public void charSummary(String name, String[] statNames, int[] stats)
 System.out.println("\n------ " + name);
 for(int index = 0; index < stats.length; index++)
 System.out.println(statNames[index] + ":\t" + stats[index]);
 }and Play class
public class Play
 public static void main(String[] args)
 Player player = new Player();
 String name = player.setName();
 player.setStats(points, stats);
 }Now you can access names , you can't assign keyword to variable into method scope , make it class variable .
Hope it help :)

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.

Subject: Re: [iPlanet-JATO] Use Of models in utility classes -Pease don't

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-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getSession().]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>

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.

Subject: Re: [iPlanet-JATO] Use Of models in utility classes -Pease don't
forget about the regular expression potential
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-match>
<mapping-rule-substitute>
<![CDATA[RequestManager.getSession().]]>
</mapping-rule-substitute>
</mapping-rule-replacement>
</mapping-rule>

I need a clarification : Can I use EJBs instead of helper classes for better performance and less network traffic?

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer

Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
2) for less network traffic
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
3) for better container resource utilization
Again, the EJB version will consume a lot more container resources.

Hi
Creation of Material using BDC Session method & global class by using oops.
can anyone plz help me out

Hi,
it looks like it's not possible to call this BAPI wihtout material number. Here is a quote from BAPI documentation.
When creating material master data, you must transfer the material
number, the material type, and the industry sector to the method. You
must also enter a material description and its language.

QoS: Multiple acl entries cannot be used in match-any in class Match_XY

Hello All,
I'm getting below error while trying to add the two extended ACL in the class-map for classifying the traffic. Is there any way I can add two extenteded ACL in the same class-map for classifying the traffic.
Error log: "QoS: Multiple acl entries cannot be used in match-any in class Tag_AF13"
device details: cisco WS-C6506-E with Supervisor Engine 2T
IOS version -s2t54-adventerprisek9-mz.SPA.150-1.SY1.bin

#match access-group name XY
QoS: Multiple acl entries cannot be used in match-any in class Tag_AF13
Regards,
Thiyagu

Hi Rajan,
Thats because of the logic used for ACl operations, as per your config you are class-map match-any. The match any argument says that the class map must match either of the two arguments supplied.So lets take a look at how the sequence of operations of how this will be interpreted by your class map.
1> Any particular packet will be first matched against the first ACL "XX".
2> Suppose there are 10 entries there if it matches any of those entries the appropriate action will be talen.
3> If none of those entried match the packet there will be an implicit deny at the end of the ACL( default behaviour of ACL's)
4> In that case the packet will match the implicit deny and will get dropped.
5> The packet will under no circumstances go to the next ACL "XY"
Thats the reason multiple ACL's aren't allowed by the IOS.
You can try to collate both ACL's and put them in just one ACL that should work well. If you need help please pots both the ACL's.
Please do let me know if you have any further questions
HTH

Umesh

why i m not able to use repaint() method in tower class? from where i can use repaint() method

i can't read your code - not formatted with code tags
I have no chance of getting it to compile (AboutDialog class?? p.draw() ??)
here's a basic routine - add a couple of things to this to demonstrate what is not
being redrawn
(compare the readability of below code (using tags) to yours)
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class Testing extends JFrame
public Testing()
 setSize(400,300);
 setLocation(400,300);
 setDefaultCloseOperation(EXIT_ON_CLOSE);
 final DrawPanel dp = new DrawPanel();
 JButton btn = new JButton("Change Text Location/Repaint");
 getContentPane().add(dp,BorderLayout.CENTER);
 getContentPane().add(btn,BorderLayout.SOUTH);
 btn.addActionListener(new ActionListener(){
 public void actionPerformed(ActionEvent ae){
 dp.x = (int)(Math.random()*300);
 dp.y = (int)(Math.random()*150)+50;
 repaint();}});
public static void main(String[] args){new Testing().setVisible(true);}
class DrawPanel extends JPanel
int x = 50, y = 50;
public void paintComponent(Graphics g)
 super.paintComponent(g);
 g.drawString("Hello World",x,y);
}

Problems using different tables for base class and derived class

I have a class named SuperProject and another class Project derived from
it. If I let SchemaTool generate the tables without specifying a "table"
extension, I get a single TABLE with all the columns from both classes and
everything works fine. But if I specify a "table" for the derived class,
SchemaTool generates the derived class with just one column (corresponds
to the attribute in derived class). Also it causes problems in using the
Project class in collection attributes.
JDO file:
<jdo>
<package name="jdo">
<class name="Project" identity-type="application"
persistence-capable-superclass="SuperProject">
<extension vendor-name="kodo" key="table" value="PROJECT"/>
</class>
<class name="SuperProject" identity-type="application"
objectid-class="ProjectId">
<field name="id" primary-key="true"/>
</class>
</package>
</jdo>
java classes:
public class Project extends SuperProject
String projectSpecific
public class SuperProject
BigDecimal id;
String name;
tables generated by SchemaTool:
TABLE SUPERPROJECTSX (IDX, JDOCLASSX, JDOLOCKX, NAMEX);
TABLE PROJECT(PROJECTSPECIFICX)
Thanks,

Justine,
This will be resolved in 2.3.4, to be released later this evening.
