Urgent help needed(java frames)
Hi,
I need urgent help for correcting a piece of code.
I have written a piece of code for building a gui with some buttons, drawing some geometric shapes.The code consists of two files called Graph and Frame.
The problem I suppose in the last part of the Graph file, which Rectangle and Circle are called together, the only shape that the program draws is rectangle.Here is the code:
//Graph

MarinaHi,
You are very lucky that I'm currently boored. You should never tag a question as urgent. It might be urgent to you, but not to us who answer. And you should also use code formatting when you post code (see the formatting tips, or use the code-button).
I made some changes to your Graph class. The most important thing is the abstract draw method that I added to the GeomFigur class.
import java.awt.*;
import javax.swing.*;
import java.util.*;

this.p2 = new Point(p2);
public String toString() {
return "Line from " + p1 + " to " + p2;

Urgent HELP required on forming the Matrix of data using PL/SQL
Hi All,
I'm new to this thread and require your urgent help in this regard.
I've got a requirement for building a 5000 X 5000 matrix using PL/SQL. My original data tables have 5000 rows each and I need to do a correlation analysis using this data and need to store in a physical table and not in-memory. Is this feat achievable using mere PL/SQL? I understand that Oracle DB has a limitation of 1000 columns(but not sure) and hence I'd like to know whether there is any work-around for such scenarios. If not, what are the other alternative method(s) to achieve this feat? Do I need to use any 3rd party tools to get this done? An early reply from the experts is highly appreciated.
Thanking you all Gurus in advance.
Rgds
SaiWelcome to OTN!
I'll get to your quesiton in a moment, but first some welcome information. Many OTN posters consider it impolite to mark threads as "urgent". We are volunteers and have jobs of our own to do without people we don't know making demands. You are brand new and deserve some patience but please understand this. It is very likely before I finish this post someone will complain about the word "urgent" in your subject.
On to more interesting things :)
You can do the matrix, but are out of luck with a 5000 x 5000 table because Oracle only allows 1000 columns per table. There are ways to work around this.
How do do the matrix depends on what you want to do. You can do this different ways. You can create a table beforehand and use PL/SQL or simple SQL to populate it, or use the CREATE TABLE AS syntax to create and populate it in one step if you can get the underlying SQL to work the way you want, something like
create table my_table as
select a.*, b.*
from table1 a, table2 bcan populate a matrix from 2 tables with an intentional cartesian join (the WHERE clause was left out intentionally, provided your data is already in the data base.
If not you can use a PL/SQL routine to populate the data.
There are a couple of ways to solve the 1000 column limit. The easiest way might be to have 5 collections of 1000 columns each. A more complicated but more elegant soltion would be to have nested collections, allowing 2 colliections that you can loop through - a collection of collections. Nested collections can be hard to work with. A third way would be to use nested tables in the database but I personally do not like them and the insert, update, and delete statements for nested tables are hard to use.
I'm not going to give a code example because I am not sure which solution is best for you. If you have further questions post them. -
Urgent Help required! - Storing the XML as String instead as a file
Hi,
I need urgent help on this.
I have an XML file. I have used org.w3c.dom to build dom and manipulate the XML file.
I have updated the values for some of the nodes and I have deleted some of the unwanted nodes.
I am able to save the output of the DOM as another XML file using
either transform class or XMLSerializer with OutputFormatter class.
But my requirement is to save the output of the DOM into a String instead of a file.
When I save it in String, I need to have the following XML decalration and DOCTYPE declration also with it.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Test SYSTEM "Test.dtd">
Can anyone pls help me in this??
Thanks in Advance. Expecting some inpputs pls....!
Regards,
Gayathri.hi,
i think this is what u want
public static String getXmlString(Document d) {
StringWriter strResponse = null;
try {
OutputFormat format = new OutputFormat(d);
strResponse = new StringWriter();
XMLSerializer serial = new XMLSerializer( strResponse, format );
serial.asDOMSerializer();
serial.serialize(d.getDocumentElement());
catch (Exception e) {
System.out.println(e.toString());
return strResponse.toString();

What is the role of java in the netweaver platform
Hi All
sapnetweaver platform is the integration of the java and abap.then what is the role of java in that netweaver platform
regards
SunilHi Sunil,
Java makes Sap NetWeaver more powerfull than it was before.
One of the new additions to the Java functionality of NetWeaver includes the Java Virtual Machine container technology. This will allow standard Java code to run on a framework around the Java Virtual Machine itself. It does this by reducing the number of parallel users per virtual machine. It also improves on the overall memory consumption, the application stability and the number of affected users in the event of a screen freeze, loss of data or the need for re-keying of information.
The JVM technology also includes several added features designed to assist developers in managing error resolutions. This includes the ability for developers to switch a user process in the production system in or out of debugging mode on the fly allowing for minimum downtime. While also including tracing and monitoring tools for error analysis and hopefully a quick resolution.
So now, not only does NetWeaver offer support for such standards as HTTP, XML, Web services and of course ABAP, but now it also offers support for Java. All of this adds to SAPs future interoperability with such applications as Microsoft .NET and IBM WebSphere.
Now that SAP NetWeaver supports Java we will start to see a real positive impact in the marketplace for those who are in search of a cost-effective means to deploy and manage Java applications in their enterprise and small businesses. For companies of all sizes looking for a way to adapt quickly to market changes, respond to unforeseen challenges and to seize new opportunities, SAP NetWeaver is a tool that is worth looking into. -

*URGENT HELP REQUIRED* java.sql.SQLException: Invalid Oracle URL specifed
Hi all,
In the middle of the last week for my final year project and having to convert to an Oracle database due to compatibility problems with university Tomcat Server and MS Access. I'm having trouble connecting to the Oracle database and would appreciate some help please.
Running on Windows 98 in the lab here, and the Oracle 9i, release 9.2.0.2.0, J2SDK1.4.0, Classes12.zip installed OK.
Code for connection looks like this inside the constructor of my class:
Class.forName("oracle.jdbc.driver.OracleDriver");
cardSaleConnexion = DriverManager.getConnection("jdbc:oracle:[email protected]:1521:sid","user_name","pwdt");
System.out.println("Connection Successful ");
And I'm getting the following error when calling the constructor in a driver program:

Need some urgent help with Java code...
Hello
i am taking a java class..beginner..and i am a dud at programming...
had a couple of questions ..how do make a program ignore negative
integer values,make it terminate when zero is entered instead of a number ,how should i calculate maximum minimum of integers..please help me..
thanks
daminiYou got some good advice from Java_Jay.
Here is a snippet I keep handy for console input and output. It doesn't do your home work but gives you a working example of getting numbers from stdin:
import java.io.*;
public class DemoKeyboardInput {
public static void main(String[] args) throws IOException {
// open keyboard for input (call it 'stdin')
BufferedReader stdin = new BufferedReader(new InputStreamReader(
System.in), 1);
// get input from the keyboard
System.out.print("Please enter your name: ");
String name = stdin.readLine();
System.out.print("Please enter your age: ");
String s1 = stdin.readLine();
System.out.print("Please enter the radius of a circle: ");
String s2 = stdin.readLine();
// perform conversions on input strings
int age = Integer.parseInt(s1); // string to int
double radius = Double.parseDouble(s2); // string to double
// operate on data
age++; // increment age
double area = Math.PI * radius * radius; // compute circle area
// output results
System.out.println("Hello " + name);
System.out.println("On your next birthday, you will be " + age
+ " years old");
System.out.println("Area of circle is " + area);
} -

URGENT Help: Converting JAVA ALE API (9.3) to MDX API (11.1.1)
Hi All,
currnetly I am in the process of converting ALE to MDX API as ALE is no more used
com.hyperion.ap.IAPMdMember in ALE Api gives the member details like Alias, level, Gen etc
Equivalent to IAPMdMember , In MDX there are two
1.com.essbase.api.metadata.IEssMember -> It gives all the member details like Alias, level, Gen etc
IEssMember metatdata extraction is very slow. need to increase maxport user as Goodwin said.Even then for 10 lakhs metadata it fails at one point or other (Using outline or member selection every thing fails)
SEVERE: Cannot get members. Essbase Error(1007165): Cannot obtain new member handle. The maximum number of open member handles for this outline has been reached. You must save and close the outline to continue
2. com.essbase.api.dataquery.IEssMdMember - It gives members Name/alias based on Query setting and some properties like readonly etc.
This IEssMdMember metadata extraction is very fast. Even 10 lakhs data is retrieved ina minute, but I am in need of Alias, level and Gen to frame the metadat as Nodes (or in bean object with same hierarchy)
can some Java MDX experts help me.Is there any to access member details like geb, level, alias using IEssMdMember? I searched in API i couldnt find any clue. converting IEssMdMember to IEssMember using outline findmember also time consuming and it taking 2 to 3 days to fetch the 10 lakhs record.
If there is no way to get details , then give me some tips how it can be managed, by cache technology or threading or is there any fastest collection object availableAdd the below DIMENSION properties in MDX query will provide the Gen_Number, level and alias
DIMENSION PROPERTIES MEMBER_ALIAS ,GEN_NUMBER ,LEVEL_NUMBER,MEMBER_NAME on columns

URGENT HELP about java.util.zip.ZipException: invalid entry CRC
I have a program (JAVA of course) packet on JAR with fat-jar eclipse plugin. This program work well in all my computers except two. On these two computers I receive a java.util.zip.ZipException: invalid entry CRC.
Both computers have the last version of java, but one is Windows and the other is Linux.
Any help to find the source of this problem??
Thanks in advance.Sorry, I give poor information about this problem.
This is the full error showed when I execute this command: java -jar app.jar
Unable to load resource: java.util.zip.ZipException: invalid entry CRC (expected 0x358054d7 but got 0x7dc370ba)

app.jar is a JAR file created with fat-jar eclipse plugin, to make easier to generate a JAR file with all dependencies.
I think that is not a code related problem, because this program is executed in several computers without errors.
I trasport this JAR to the client computer via HTTP.
I'm trying to find clues to find the origin of this problem.
Thanks.
