JCoIDoc IDocLibrary 3.0.2 Problems with IDocServerExample.java

Hello, I´m facing a problem with IDocServerExample.java. I created a new project in eclipse, added the package com.sap.conn.idoc.examples and the class IDocServerExample.java. I configured the files "MYSERVER.jcoServer" and "BCE.jcoDestination" and started the application. Then I get the following error messages: *********************************************************************************************************************************************************

Solution Manager systems RAM requirements - problems with the Java Engine

Hello,
I am about to install SAP Solution Manager 7 on a WIndows 2003 Server x64 but I need to know what the RAM requirements are? I have been having problems with the Java Engine starting and it seems to time out, I have heard that this is a very RAM hungry process and it might be why?
Many thanks for your help in advance,
Omar

Hello Omar,
To size SAP Solution Manager 7.0 EHP1 we recommend to use the SAP Solution Manager Quicksizer Tool at:

Performance problems with new Java Tiger style recommendations

Performance problems with jdk 1.5 on Linux plattform
(not tested on Windows, might be the same)
using the new style recommendations.
I need fast Vector loops for high speed mathematical calculations, some
hints about the fastest way to program that loop would be also great!
After refactoring using the new features from java 1.5 (as recommended from
SUN) I lost performance significantly:
using a vector:
public Vector<unit> units;
The new code (recommended from SUN for Java Tiger for redesign):
for (unit u: units) u.accumulate();
runs more than 30% slower than the old code:
for (int i = 0; i < units.size(); i++) units.elementAt(i).accumulate();
I expected the opposite.
Is there any information available that helps?
The following additional information I got from Mr. Shankar Unni:
I got some fairly anomalous results comparing ArrayList and Vector: for the
1.5-style loops, ArrayList was faster then Vector, but for a loop with get()
calls, Vector was faster. Vector was even faster than that using
elementAt(), which was a surprise:
For a million summing iterations over a 100-element array:
vector elementAt loop took 3446 ms.
vector get loop took 3796 ms.
vector iterator loop took 5469 ms.
arraylist get loop took 4136 ms.
arraylist iterator loop took 4668 ms.

A problem with my Java Scrabble game

Hello
I am making a Java Scrabble game for a school assignment and I have a problem with the following:
The number of players is input by the user (2 to 4) and i need to create a number of arrays based on the number of players. These arrays must have 7 playing pieces at all times until the "bag" of pieces has less pieces than those required to replace the ones a certain player just used (in wich case the bag would give that player all of it's remaining pieces and, from this point on, the player arrays would not necessarily need to have 7 pieces).
this is my procedure to take a piece from the bag:
     public Piece takePiece()
          if (this.pieceCounter > 0) {
               Arrays.sort(this.pieces, 0, this.pieceCounter);
               int i = this.generator.nextInt(this.pieceCounter);
               Piece p = this.pieces;
               this.pieceCounter--;
               this.pieces[i] = this.pieces[this.pieceCounter];
               return p;
          else
               return null;
this is my Piece class:
public class Piece implements Comparable {
     private int scorePiece;
     private char letterPiece;
     public Piece(char letterPiece, int scorePiece)
          this.scorePiece = scorePiece;
          this.letterPiece = letterPiece;
     public int scorePiece()
          return scorePiece;
     public String letterPiece()
          return letterPiece();
     public String toString()
          return letterPiece+ " " + scorePiece;
     public int compareTo(Object a)
          Piece piece= (Piece) a;
          return (int) letterPiece - (int) piece.letterPiece;
}Thanks in advance for your help

Ok, if i create a Players class and do this in Main class:
     if(nPlayers >= 2 && nPlayers <= 4)
          Players arrayPlayers[];
          arrayPlayers= new Players [nPlayers ];
          for(int i=0 ; i < nPlayers ; i++)
                   arrayPlayers[i] = new Players ();
          }My Players Class should contain something like this:
         // Array of 7 that contains Pieces...
     Piece[] pieces= new Piece[7];how can i get pieces from takePiece(); (Class Bag) and put them in the pieces arrays until takePiece(); returns null?

Problems with VA Java Visual Composition

Hi!
I have some problems with reopening (even simple) visually in VA Java created
beans (JFrame, JDialog). IDE behaves somehow unpredictable. Sometimes it reopened it into the
visual composition editor, anothe time the reoppening fails with following log message:
Java exception during layout of bean(<unnamed>): java.lang.NullPointerException
Java exception during layout of bean(JFrameContentPane): java.lang.NullPointerException
An exception occurred in a system program.
Terminating TimeSlotGUI (VCE) (System) (25/07/01 10:05:07)
Can anybody help?
Ivan

Which Version do you use? This VAJ 3.5 was quite bugy and you had to use patches. Now there is an Update 3.5.2 which fixes most of the bugs ( although there are new ones). When I work with the VCE ( avoid this normally) I get problems if I rename Beans which were generated with th VCE. then your stuff is lost. Sometimes you can recover if you delete the generated[i] initialize() method and then open the VCE.
Nevertheless, VAJ 3.5.3 works quite good, great debugging tools.

Problem with Sun Java Creator JDBC driver .....

Hi:
I am new to Java Studio Creator. I am using Oracle Enterprise Edition 8.0.5.0 database to get data from. Through Servers Navigator->Data Sources, I define a new datasource using default JSC JDBC driver for Oracle. However, when I try to test the connection I get the following error.
[sunm][Oracle JDBC Driver] Internal Error: Net8 Protocol Error
Can someone tell me what is going on here? By the way I also have Netbeans 4.0 IDE which works fine with the same database.
-Victor bagga

I was using the following database URL.
jdbc:sun:oracle://autoserv.cqtel.com:1521;SID=autosvdb
The SID is valid because I can use other JDBC drivers such as Oracle's thin driver which uses the Database URL
jdbc:oracle:thin:@autoserv.cqtel.com:1521:autosvdb
and it works. However, I can not use the Oracle thin JDBC driver with Sun Java Creator as it seems to be incompatible. Using this driver I can successfully define a datasource and veiw all the data and make all kind of queries through the Server Navigator window but when I try to drop a database table on to a Data Table in my project, nothing happens. If I try to Edit the query on the rowset, the GUI window does not show any Column names and display names.
By the way, I also have an Oracle 9.x database which works just fine with Java Ctreator Studio. I really like Java Creator as I find it very productive but not being able to make it work with Oracle 8.0.5.0 takes the fun out of it.

Problem with Cut.java sample

I am attempting to use code from the Cut.java sample to cut multiple
regions from the same source audio file to separate destination files.
I am calling the doIt() method from my coding, passing MediaLocators to
the input and output files (both .wav) , and arrays with a single
element (time in ns as a long) for the start and end, and false for
frame mode. The first time I call it, it works fine. However, on
subsequent calls, despite the output messages suggesting it has worked
successfully, the output files are full of white noise. I have tried:
using a new instance of Cut each time
adding code to close the processor and disconnect the datasink
disabling JMF buffering
all to no effect. Any suggestions would be greatly appreciated.
cheers
Matthew Wilson.

Having problems with a Java Telnet Client

I'm trying to write a Telnet Client(for a mud). I've searched the forum but can't seem to find the answer to my problem. The mud sends the ANSI color codes, is there anyway to get java to interpret this, or will I have to make a parser and do all the work by hand?

Try looking up RFC854 & RFC855. A Google Search will give several references. Other Searches include "Interpret As Command", and "Telnet IAC Options".
The keys to telnet communications:
1. Unless it is explicitly a command, it is data.
2. All Commands start with the Interpret As Command (IAC) character, decimal 255 or hexidecimal ff.
3. IAC DO/DONT/WILL/WONT Negotiations for a Telnet Option occurs before IAC SB/SE Subnegotiations. DON'T/WON'T is the default Telnet Network Virtual Terminal (NVT) setting for all options.
4. All Negotiations complete before you get to the data phase.
5. Be ready for Negotiations, at the start and during the middle of the Telnet Session....
Here is an example of decoding Telnet
The remote host may start with the following, shown in decimal:
255, 253, 3, 255, 253, 24, etc...
Viewed as UTF text, this appears to be some "y" characters with special accents above them.
Cheat Sheet:
255 == Interpret As Command (IAC)
254 == DON'T, as is "I DON'T support xyz...."
253 == DO, as in "I DO support xyz..."
252 == WON'T, as in "You WON'T support abc..."
251 == WILL, as in "You WILL support abc..."
250 == SuBnegotiations Start (SB)
240 == Subnegotiations End (SE)
The above has 2 commands:
- 255, 253, 3 == IAC DO Suppress Go Ahead
- 255, 253, 24 == IAC DO Terminal Type
Appropriate Responses could be:
- 255, 251, 3, 255, 251, 24, etc....
OR
- 255, 252, 3, 255,252, 24, etc...
OR
- 255, 251, 3, 255, 252, 24, etc...
OR
- 255,252, 3, 255, 251,24, etc...
Once you get the remotes questions answered, you can move on to the real work of passing data.
Cheers,
Joel.

Problems with a Java socket client

Hi,
I'm using the following piece of code to recieve from a C++ server a string of chars:
TcpCli = new Socket(m_HostIP, m_HostPorta);
String msg="";
int lenSocketBuffer=0;
BufferedInputStream in = new BufferedInputStream(TcpCli.getInputStream());
lenSocketBuffer=in.available();
if (lenSocketBuffer > 0)
saveBuff = new byte[lenSocketBuffer];
in.read(saveBuff,0,lenSocketBuffer);
msg = saveBuff.toString();
I have verified that the creation of the Socket is OK (using debug on the Server side) and that the Server sends to the Client what I expect to receive. The length of the buffer read in lenSocketBuffer is OK but when I receive the buffer using in.read I find a string that is something like this: "[B@7b6889" which is a completely different buffer from what the server sends and much more shorter then the value of lenSocketBuffer.
Where is the problem? Please, help me.
Thank you.

replace...
msg = saveBuff.toString();
with...
msg = new String(saveBuff);
saveBuff.toString() returns the string-representation of the object saveBuff. new String(saveBuff) creates a new String-Object with the bytes of the given array.

Problem with creating JAVA Source. please help

Dear all
how are you.
In fact I have made a simple java class that return a string which represents the screen size . for example 800/600 or 1024/768 or others
but I face error ORA-29541 class string.string could not be resolved
This what i made
first i created my JAVA Source
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "ScreenProperty" AS
import java.lang.Object;
import java.awt.*;
public class ScreenProperty
int w;
int h;
public static String getScreenSize()
w = Toolkit.getDefaultToolkit().getScreenSize().width;
h = Toolkit.getDefaultToolkit().getScreenSize().height;
return w+"/"+h;
SQL>Operation 160 succeeded.
this means the the java source created successfuly
and I'm sure that my java code is correct
then i created a fuction to call this java source as fellow
SQL> create or replace function f_get_screen_size
return varchar2
as language java
name 'ScreenProperty.getScreenSize() return java.lang.String';
Function created.
the I Issued this sql statement to return the result that should be varchar2 that represent the sceen size(1024/768)
SQL> select f_get_screen_size from dual;
ORA-29541 class string.string could not be resolved.
I do not know what is the reason for this error
and when i searched the documentation for this error i found
ORA-29541 class string.string could not be resolved
Cause: An attempt was made to execute a method in a Java class that had not been previously and cannot now be compiled or resolved successfully.
Action: Adjust the call or make the class resolvable
I need to know what is the problem.
And is there another way to load this class other than making JAVA SOURCE
please help

before drawing hands of clock you could fill a circle/oval with certain color, then you'd have that kind of circle that has been filled as backgound.
you may change those dots to be small lines for 12, 3, 6 and 6 o'clock and then have small dots represent 1, 2, 4, 5, 7, 8, 10 and 11 o'clock
anyhow, you should study that code and see how you can modify it whitout breaking it but having it look different.
better yet would be trying to understand how it works, what any line there means and then recreate your own... this way you would learn more....
and if there are some methods or anything you don't understand, then look them up from API documentation
good luck.

Problem with MixingFloatAudioInputStream.java available() method

I've always been under the impression that the available() method for an AudioInputStream +returns the maximum number of bytes that can be read (or skipped over) from this audio input stream without blocking+.
Unfortunately, this doesn't seem to be the case for the available() method in the MixingFloatAudioInputStream class (found on jsresources).
      * The minimum of available() of all input stream is calculated and
      * returned.
     public int available() throws IOException {
          int nAvailable = 0;
          Iterator streamIterator = audioInputStreamList.iterator();
          while (streamIterator.hasNext()) {
               AudioInputStream stream = (AudioInputStream) streamIterator.next();
               nAvailable = Math.min(nAvailable, stream.available());
          return nAvailable;
     }Is there a reason why this specific method returns the minimum as opposed to the maximum number of bytes? Can I simply just modify the Math.min function to Math.max to revert it back to its normal behavior?

Once again, great explanation.
Like you noticed, I thought that the available() method implied total length minus amount processed so far... Because of this, I decided to use it to measure the length of an InputStream, used in an audio fade class (I've started another thread on this topic with more details).
public FadeFilterInputStream(InputStream inputStream){
        super(inputStream);
        try {
            streamLength = super.available();
        } catch (Exception e) {
                e.printStackTrace();
                System.exit(0);
        fadeLengthBegin = (int) ((0.8)*streamLength);
        fadeLengthEnd = (int) ((0.15)*streamLength);
} Seeing that FadeFilterInputStream extends FilterInputStream, I can only use an InputStream. Unfortunately, unlike the AudioInputStream, it doesn't have a getFrameLength() method to measure the length of the stream. I tried getting creative with the "available()" method instead.
What got me thinking that the available() method implied total length minus amount processed so far was the following output from my code:

...Like you mentioned, seeing that the combined AudioInputStreams were all the same length, it didn't cause me any problems when I modified the method to find the maximum length of the longest stream. From your explanation, this might not be the case if I decide to combine streams of different lengths.
Using the available() method to measure the total length of the InputStream is probably not the best way to approach this problem. Any ideas?
+On a side note, according to your example, shouldn't the available() method be returning the same value until the end (in this case 2 seconds worth of bytes)? That doesn't seem to be the case from my output.+

A problem with importing java.util.concurrent

I am rather new to Java with not that much experience. I apologize ahead though if this is the inappropriate forum to post this problem and/or this question has been answered somewhere else (I couldn't find a post on this subject).
Some of my research has lead to using a semaphore if you wish to use the synchronized() method. I looked up that the import for that is under java.util.concurrent.Semaphore; however, thanks to netbeans for pointing this out before I compiled it, this doesn't seem to exist.
I'm using Java version 1.6.0_03 which does seem to be the latest version. Was it simply removed or am I seriously missing something big here? Anyways, I'm at a total loss and hopefully someone can point me in the right direction.
Thank you in advance for your help.

check whether import java.util.concurrent.*; is workingAwesome.
As for netbeans, I went and double checked to see if it is reading from the most updated folder of Java and it is.
So as I said, I am totally lost as to why it's not working. Should I just downgrade to a lower version of Java? Although it would seem kinda weird to do something like this.

Problems with basic Java JPanel animation using paintcomponent

okay so I am trying to animate a sprite moving across a background using a for loop within the paintComponent method of a JPanel extension
public void paintComponent(Graphics g){
Image simpleBG = new ImageIcon("Images/Backgrounds/Simple path.jpg").getImage();
Image mMan = new ImageIcon("Images/Sprites/hMan.gif").getImage();
if (!backgroundIsDrawn){
g.drawImage(simpleBG, 0, 0, this);
g.drawImage(mMan, xi, y, this);
backgroundIsDrawn=true;
else
for (int i=xi; i<500; i++){
g.drawImage(simpleBG, 0, 0, this);
g.drawImage(mMan, i, y, this);
try{
Thread.sleep(10);
} catch(Exception ex){System.out.println("damn");}
The problem is that no matter what I set my thread to, it will not show the animation, it will just jump to the last location, even if the thread sleep is set high enough that it takes several minutes to calculate,, it still does not paint the intemediary steps.
any solution, including using a different method of animation all together would be greatly appreciated. I am learning java on my own so i need all the help I can get.

even when I placed the thread sleep outside of the actual paintComponent in a for loop that called repaint(), it still did not work? Nope. Doing this will likely put the Event Dispatch Thread or EDT to sleep. Since this is the main thread that is responsible for Swing's painting and user interaction, you'll put your app to sleep with this. Again, use a Swing Timer
and is there any easy animation method that doesnt require painting and repainting every time becasue it is very hard to change what I want to animate with a single paintComponent method? I don't get this.
I find the internet tutorials either way too complicated or not nearly in depth enough. Maybe its just that I am new to programming but there doesn't seem to be a happy medium between dumbed down Swing tutorials and very complicated and sophisticated animation algorithmns.I can only advise that you practice, practice, practice. The more you use the tutorials, the easier they'll be to use.
Here's another small demo or animation. It is not optimized (repaint is called on the whole JPanel), but demonstrates some points:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
