Accessing user-defined package

I have two packages 'A' and 'B' at same directory level.
How can I access the methods/files in one package from another package.
i.e., I want to access file_A.put() in (package 'A') from file_B (package 'B').
Is it possible to do so?
If yes, then how can I do this?

Check Using Package Members section of the Learning the Java Language tutorial.

How to use user-defined packages in JAX-RPC web service

I am trying to use Object of my class located in my package in jax-rpc webservice,the code is
package supercomputer;
import Hello.*;
public class SuperImpl implements SuperIF
public String sendParam(String data)
Temp ob=new Temp();
int i=ob.get1(10000);
return data+"returned by supercomputer";
Temp is located in Hello package,I have jar the Hello package as Hello.jar and has set its classpath in targets.xml of Ant tool.
The code compiles well and service is deployed successfully,but when i try to call the service from the client its gives me following error.
[echo] Running the supercomputer.SuperClient program....
[java] java.rmi.ServerException: Missing port information
[java] at com.sun.xml.rpc.client.StreamingSender._raiseFault(StreamingSender.java:357)

[java] at supercomputer.SuperIF_Stub.sendParam(SuperIF_Stub.java:60)
[java] at supercomputer.SuperClient.main(Unknown Source)
I dont know if it deploys why it gives error on client side.
Please tell how to use user-defined packages and class in jax-rpc service code ,i am not talking about passing user-defined parameters i am just talking about making objects of user defined classes in jax-rpc service.I think there is some problem in classpath.
Please guide me in doing that.
Thanks,
Farrukh

Farrukh,
I don't know if your error is about a missing class from your custom package, ... what track did you followed to say that?
To use your package in the implementation of you web service, you should only follow the rules of making a web application: put your package jar in your \lib directory inside WEB-INF/ or your package classes unjared in classes (also in WEB-INF/).
As I already said, I have doubts that your error should be originated from a missing class from your package, but:
-try to see the logs (errors?) when you deploy your web service that could give a hint about the problem.
-try to see if you can access your endpoint through your browser to see if there is a online status
-display your config/WSDL file, and the steps you did to build your web service.

How to make an applet load user-defined package?

How to have an applet load user-defined package?
I have packages in their own directories, and the applet compiles and links with them, by use of CLASSPATH env variable. But when it comes time to run, it ignores that and does not know where the classes (in the packages) are.
If I don't use packages and put all code in one directory, runs fine. If I use an application, I can link with and load my packages.
I know applets can't use things like CLASSPATH for security reasons, but still, they should be able to be compiled out of several packages, why do I have to put all code together??

OK, for reference for future newbies, here's the answer:
use CODEBASE attribute in your html file (if on Windows server, don't use drive letter but relative path to .html file, Unix style, and put all your .class files beneath that, for example, in your .html file
<applet
CODEBASE="..\class
and then have package bar Bar.class file, in ..\class\bar

Creating User Defined Package Groups

Hi everyone!
I'm currently exploring/experimenting with strategies to stabilize parts of the Arch system on machines which I plan do update less frequently (I am aware of the risks and the potential difficulties associated with infrequent updates; that's why this is an experiment). It seems to me that Package Groups would be an asset which could be leveraged for a few different strategies. However, I cannot find any documentation on creating user defined package groups. Is there a way to do this? Any documentation anyone could point me to would be awesome. Thanks!

You can compile the package yourself or change just the metadata. I think xyne had a tool for that, if only I could remember the name ...
Edit: It's repkg https://bbs.archlinux.org/viewtopic.php?id=158970
Edit 2: What do you need package groups for anyway? You should update the whole system rather than individual packages / groups of packages.

Accessing User Defined Types

We have recently updated our libraries to the latest version (2.102.2.20) - and have lost access to the critical objects and methods that were accessing our User Defined Types on Oracle.
In particular, this code:
OracleUdtDescriptor descriptor = OracleUdtDescriptor.GetOracleUdtDescriptor((OracleConnection)conn, "MY_USER.MYTYPE");
OracleArray items = new OracleArray(descriptor);
foreach (string s in testArrayItems)
items.Append(s);
IDbDataParameter itemsParam = cmd.OracleParameters.Add("items", OracleDbType.VArray, items, ParameterDirection.Input);
simply doesn't work anymore. The 'OracleUdtDescriptor' and 'OracleArray' references no longer exist. This has brought all development on a critical application to a halt. (Doesn't it always.)
How can I get the same functionality using the new version (2.102.2.20) of the Oracle.DataAccess library?

Hi,
Here's what I was referring to... say you wanted to execute the same procedure from PLSQL via an anonymous block. Execute the same anonymous block via ODP.NET.
Here's a simple dumb example that passes an object type to a stored procedure, hope it helps. Hokey example, but hopefully points out what I was trying to say.
Greg
SQL
========
create or replace type person_typ as object (name varchar2(50), age number(4))
create table person_tab(col1 number, col2 person_typ);
create or replace procedure insert_person_proc(v1 in number, v2 in person_typ) as
begin
insert into person_tab values(v1,v2);
end;
You could execute that via PLSQL as follows
=================================
declare
myperson person_typ;
begin
myperson := person_typ('melody',5);
insert_person_proc(1,myperson);
end;
/And do the same thing via ODP.NET
=============================
using System;
using System.Data;
using Oracle.DataAccess.Client;
class Program
    static void Main(string[] args)
        using (OracleConnection con = new OracleConnection("data source=orcl;user id=scott;password=tiger"))
            con.Open();
            using (OracleCommand cmd = new OracleCommand("",con))
                string strsql = "declare " +

Hi everyone,
I am new to java programming.I am trying to do a small program to see how the user-defined pckages work.I wrote 2 small programs one is Balance.java and TestBalance.java.
The code for Balance.java is as follows..
package MyPack;
public class Balance{
        String name;
        double bal;
        public Balance(String n, double b){
                name = n;
                bal = b;
        public void show(){
                if(bal < 0)
                     System.out.print("--->");
                  System.out.println(name + ": $" + bal);
      }The code for TestBalance.java is as follows..
import MyPack.*;
class TestBalance{
        public static void main(String args[]){
                Balance test = new Balance("Leela",99.88);
                test.show();
}These r both in the same directory....I am able to compile Balance.java...but when I try to compile TestBalance.java I am getting the following errors

99% going to work
i have noticed some of the few thing
trying to help
u told that ur both the classes r in same directory right
ok
now ur first class has this as first line
package mypack;//till here its ok only "mypack" should be small case
now put this same line also in the other class as firat line
and remove that import statement since both r in same package so no
need to import it ok
here's the code
package mypack;class TestBalance{        public static void main(String args[]){                Balance test = new Balance("Leela",99.88);                test.show();           } }
now compile it this way
create a folder call mypack and put this both the classes in that folder
say its c:\mypack\ur classes
now in dos prompt
type this
set classpath=%classpath%;C:\mypack \
now u compile ur first class and then second
Surely this going to work if not tell me the errors u r getting

How can I access user defined column(in query) inside the trigger?

Hi
I have 3 unions and each query displays different records on some criteria. I also have a column hard-coded
Ex:
select a.col1, a.col2,
add as update
from table1 a
where ...
union
select a.col1, a.col2,
change as update
from table1 a
where ...
union
select a.col1, a.col2,
del as update
from table1 a
where ...
And I need to display a column in the report only if update is Add. I was thinking of writing a format trigger for that field. But I do not know how can I access this user defined column named update in the trigger?
Any help?

Try ":update" minus the double-quotes. Ex:
    IF :update = 'add' THEN
      RETURN(TRUE);
    ELSE
      RETURN FALSE;
    END IF;
You'll want to place your hard-coded values in single-quotes. Ex:
    select a.col1, a.col2,
    'add' as update

Accessing user defined fields when multiple forms as open SBO 2005

Hi
I have a program which updates a user defined field on the sales order screen. This works fine but fails to work correctly when they have more than one sales order screen open.
It updates the first sales order screen and not the active one.
Is there any easy way of accessing the correct user defined form which is attached to the active screen please ?
Code below -
            For lc = 0 To B1Connections.theAppl.Forms.Count - 1
                If B1Connections.theAppl.Forms.Item(lc).TypeEx = "-139" Then
                    form2 = B1Connections.theAppl.Forms.GetFormByTypeAndCount("-139", 1)
                    form2.Items.Item("U_bpremarks").Specific.string = orecset.Fields.Item(0).Value
                End If
            Next
Many thanks
Regards Andy

Hi Paul,
you got the point - as long as you have always the udf screens open the count is the same !
no need to say sorry

Flash Wrapper and Accessing user-defined variables

I am working on creating a Flash AS3 wrapper to combine several cpativate files. I am able to retrieve system variables, however I am not able to retrieve user-defined variables. I have a user defined variable in my Captivate called passedScore, in my Flash script I have the following...
var mcLesson1:MovieClip;
btnHit.addEventListener(MouseEvent.CLICK, test);
var vLoader:Loader = new Loader();
vLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);
vLoader.load(new URLRequest("untitled1.swf"));
function swfLoaded(e:Event):void {
mcLesson1 = MovieClip(vLoader.contentLoaderInfo.content);
vLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, swfLoaded);
addChild(mcLesson1);
function test(event:MouseEvent):void
feedback1.text = mcLesson1.cpInfoCourseName;
feedback2.text = mcLesson1.m_VarHandle.passedScore;
feedback1 correctly shows the course name, however, for feedback2 it errors saying a term is undefined (refering to m_VarHandle)

try using mcLesson1.cpEIGetValue('m_VarHandle.passedScore');

How to make user defined packages visible in Web Applications

Hello,

I use JDeveloper editor, worked hard to find the neccessary configuration but I failed. I also inserted ...... WEB-INF/classes into my classath but it didn't work.
So, could anybody tell me the main concept of introducing packages and class files to a web server ?

Accessing user-defined context variables when chaining Proxies

We have a Proxy Service, A, which routes to a ProxyService B, which does some routing and XML transformation.
When an error is raised, the error text is assigned to a variable and the Error Handler for Proxy Servce B assigns soap fault XML to the body using this variable then does a Reply with Failure.
However, Proxy Service A returns a generic BEA fault as below:
     <con:fault      xmlns:con="http://www.bea.com/wli/sb/context">
     <con:errorCode>BEA-380000</con:errorCode>
     <con:location>
     <con:node>ESB-DefaultRoute</con:node>
     <con:path>response-pipeline</con:path>
     </con:location>
     </con:fault>
We don't appear to be able to access the context variable which we defined in Proxy Service B when we are in the Error Handler of Proxy Service A. How are we able to return a soap fault from Proxy Service A with all of the details set in B.
Thanks in advance

Hi,
Yes we;re using Raise Error. I don't think my post was as clear as it could have been :-)
In Proxy B when an error is found, then the text we want to appear in the soap fault's faultstring is assigned to a varaible, errorDetail and then Raise Error is invoked.
We're able to access errorDetail iin the error handlers of Proxy B but not in Proxy A and it's this which is causing us the issue.
Thanks

Importing user defined package in JDEV

Hi,
new to the JDEV9i tool. i have a project arranged in packages and am tryin to import this to the jdev9i. i successfully created the workspace and project and added all the packages. I can also view the package tree and package list but when i run my project the files in one directory import the files from the package structure.
do i have to change Project properties?
C:\jdev9i\jdev\mywork\Workspace1\Project1\websphinx\workbench\WebGraph.java
Error(26,14): cannot access class graph.Graph; file graph\Graph.class not found

It sounds like the Class path is not set up properly. You can configure this manually from the Project Settings dialog (Project > Project Settings). Alternatively, if you import all the packages from the top level, the path should be set for you automatically. For example, if you have your work in a directory structure like this:
d:\mywork
d:\mywork\toppackage
Class1.java
d:\mywork\toppackage\subpackage1
Class2.java
Class3.java
d:\mywork\toppackage\subpackage2
Class4.java
Class5.java
You can create a new project from existing source by creating a Workspace, then selecting File > New. In the Projects category there is an item called Project from Existing Source. Launch this wizard, and select the top level package from the directory listing (d:\mywork\toppackage in the example above). You then get the option to recurse through subdirectories, picking up all the classes along the way, and the paths will be set automatically. Note that you can use the Categories View button in the Navigator to view the files by package name.
I hope this helps!

How to use classes from different user defined Packages

well i made 2 packages... one containing employee class and realted matter and other contaning bankaccounts and bank related work... now how can i use them in an another.. i know about the import statement but still couldn't make it work.... now suppose iam makin a obejct of employee class and passing in name and salary and all in the constructor... now i want that when i create the bankaccount class then the name of the employee should be passed to the bankaccount class so that it can assigen a account no. .. now how do i do this as when i create a object of employee class its made at runtime.. and if i create a object of bankaccount.. how wil it take that name as before goin to bank account i should already have a list of emplyees and then this list should be worked upon by the backaccount class to assign the accountno.s
Hope my question was clear... would appriciate a explanation and guidance!!!

Thank you so much ... i was able to solve the problem... i passed the object in the constructor of the accounts class and it all worked out the way i wanned... thank you so much... it wasn't that difficult but the idea was just not clicking...this place is wonderful... everyone rocks!!! and so greatful about all the help.. please keep up the good work and even i will try to contribute as much as possible!!

Importing User defined package problem.

Hi All,
I have made to package, "forum" and "utility". DBhandler java file is in "utility" package and Forumhandler is in "forum" package.
I want to import DBhandler classes from "utility" package into "forum" package for this i write
"import utility.*" in forum package's Forumhandler java file. But it is giving error.
The error is -
forum/ForumHandler.java:13: cannot resolve symbol
symbol : class DBHandler
location: class forum.ForumHandler
DBHandler dbhand = new DBHandler();

forum/ForumHandler.java:13: cannot resolve symbol
symbol : class DBHandler
location: class forum.ForumHandler
DBHandler dbhand = new DBHandler();
Do you have your visibility right?
The class DBHandler should be declared public.
P.s. it's a bad practice to use wildcards for imports if you just want to import a few classes, use
import my.company.product.utility.DBHandler;instead (or something similar).

Accessing user defined datatype in smartforms

I have created type group named zkttp. In that I have created a data type named zkttp_ty_sflight. I did include that in my smartform zrkt_sform_saplane. But it is showing error. This I am trying because I dont want to send all fields of sflight table in smartform. is this the right way? in smartform i have defined internal table with like as the the above datatype. still it is giving error as "TYPE ZKTTP_TY_SFLIGHT NOT ALLOWED IN THIS CONTEXT".

Ruby,
obviously there is no official way to use type-pools in SMARTFORMS, I assume what you created as type group is what you include in ABAP programs as TYPE-POOLS ZKTTP_TY_SFLIGHT.
If you put this statement inside a FORM, you can use the included types locally.
Yo don't need to define anything what is existing. In the SMARTFORMS TYPES section, you may define your own type as
TYPES:
begin of zkttp_ty_sflight,
end of zkttp_ty_sflight.
Then You can use it.
Regards,
Clemens
