How to use the random generator in java

hey peeps, this is the class in which i am trying to implement the random generator in;
public class Matchlist
    private studentdetails sd = new studentdetails();
    /** matchList StringBuilder stores the match list in progress */
    private StringBuilder matchList = new StringBuilder();

    public Matchlist()
        sd.createstudentdetails();
    /** Method to create the actual match list, returns the list as a string */
    public String CreateMatch()
        int g;
        int y;
            for (g = 0; g < 4; g++)//g = game
                for (y = 17; y > -1; y--)//y = green house
                    /** Check to see if the game is empty */
                    if (sd.getgh(y).getGame(g).equalsIgnoreCase(""))

                                        break;

            String completeMatchList = matchList.toString();
            System.out.println(matches);

                sd.getgh(i).getEmptyMatches();
            return completeMatchList;
    }what i dont understand is how to implement it to pick my matches at random using the http://java.sun.com/j2se/1.4.2/docs/api/java/util/Random.html java tutorials from here

How to use Random ?
First you open API then you read it, then you use it.
You mention you try to use it but i just see a horrible nested for for for if if if loop.
Restructure code and question and maybe it makes more sense.

How to using the executable software in Java

I got a software named: pdf to text convertor; which can format the text interface from the pdf, for example, you need add the page number with a4 paper, then the convertor can change the pdf into text with page numbers. it is running on the doc, the command like: c:\pdfconvertor\xpdfrc.exe "c:\filename\name.pdf", after the text file will exist in the same directory with the pdf file.
so my problem is how to use java to call this DOS command to execute the program, and then java can read the text file, does some one give me some idea? better with simple java code!! Thanks very much! I will pay dollar for the solutions

You can use:
String[] cmd = {"c:\\pdfconvertor\\xpdfrc.exe", "c:\\filename\\name.pdf"};
Process p = Runtime.getRuntime().exec(cmd);Wait for the process to finish:
p.waitFor()and do your thing with the output file.
Note there are mechanisms for capturing the input and output of the subprocess; see java.lang.Process javadoc.

How to use the Worklist API from Java (classpath ??)

Hi all,
Sorry for a novice question but I couldn't find the way to go about this (probably because it's such common knowldge...)
I would like to try and use the Worklist API from my Java code in Eclipse, and according to the BPEL dev-guide I need to add an Import command for oracle.tip.pc.api.worklist. Where do I find these classes ?????
I guess I need to change my CLASSPATH but I couldn't find a single word about this in the BPEL dev-guide (chapter 17), BPEL installation guide or elseware.
thanks.

Hi all,
Ok now.
To summarize - I was trying the code from BPEL developer guide, chapter 17, page 40 for using the Worklist local API's.
Only after adding the following JAR's to the build path, was I able to compile it:
orabpel-common.jar
orabpel.jar
bpm-infra.jar
bpm-services.jar
So, these 4 JAR's are required for using the Worklist local API's (not a clue in the dev guide itself for this requirement though...)
Thank you very much for your help,
assaf.

How to use the Rc4DLL.dll with java (jre1.4 )

I am not able to use Rc4DLL.dll with java, there are some characters (encrypted using Rc4DLL.dll) that java is not able to identify. So while decrypting in java using Rc4DLL I am not getting the desired output (as some character java tries to decrypt are not supported with java). Could some one give a solution of using Rc4DLL with java jre 1.4

RC4 cipher is supported by 1.4.
And surely you can turn a link to the 1.5.0 JCE Reference Guide into a link to the 1.4.2 Reference Guide? I did. Took me 5 seconds to check that. As opposed to wasting a day and a half in forums like you just did.

How to use the Java embedding activity in BPel

hi all,
How to use the java embedding activity in BPEL
pls can u provide sample example

1 Use [Oracle BPEL Process Manager Client Java API Reference|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/overview-summary.html] and especially [com.collaxa.cube.engine.ext|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/com/collaxa/cube/engine/ext/BaseBPELXExecLet.html]
Instead of System.Out.println use addAuditTrailEntry(java.lang.String message)
2. If you want to import a package write in code (Source View) of bpel process
+<bpelx:exec import="package_name"/>+ for example +<bpelx:exec import="java.util.regex.Matcher"/>+
example 1:
String bodyAsString;
StringBuffer myStringBuffer = new StringBuffer();
try {
bodyAsString = (String)getVariableData("BodyString");
addAuditTrailEntry("bodyAsString1: "+ bodyAsString);
Pattern pattern = Pattern.compile("goodDay");
Matcher matcher= pattern.matcher(bodyAsString);
while (matcher.find()) {
matcher.appendReplacement(myStringBuffer, "shitDay");
matcher.appendTail(myStringBuffer);
bodyAsString = myStringBuffer.toString();
addAuditTrailEntry("bodyAsString2: "+ bodyAsString);
} catch (Exception ex) {
addAuditTrailEntry("Failed+bodyAsString",ex.getMessage());
I put in code (Source View) the following
<bpelx:exec import="java.util.regex.Matcher"/>
<bpelx:exec import="java.util.regex.Pattern"/>
example2:
Object temp;
try {
temp = ((XMLElement)getVariableData("inputVariable","payload","/ns2:FiscalisMessage/ns2:Body")).getChildNodes().item(1);
setVariableData("AdjReceipt",temp);
addAuditTrailEntry("ok",temp.toString());
catch (Exception ex) {

How long a message can be sent via TCP using the TCP Read VI?

Hello,
How long can be a message sent between a TCP server and a TCP client using the TCP Read VI (LV2013)? There is a certain limit?
Thank you.

I think it just depends on your hardware's buffer size. TCP sets limits on the size of packets that can be seent. What are you trying to do?
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to use the DLLs which created from c++ in Java?

And How to use the DLLs which created from JNI in C++?

Huh?
Are you asking how to do JNI - you should read the tutorial.
Are you asking how to load it - then use System.loadLibrary()
Are you asking what to do with the output from javah - put it in a C file and write some code, compile it into a dll.

Can anyone tell me what is this output? And Am i deplyoing in the right way?

Hi,
You might want to check the JCDK user guide (cJDK_Users_Guide_bin_do.pdf) for details of using an emulated card environment. It outlines how to use the simulators provided with the JCDK. This should tell you how the deploy process works and will give you some insight into what this script is doing.

JNI - How to use the error reporting mechanism?

I've developed a C++ DLL which is loaded from a commercial Win32 application (not written by me) as a plug-in for external calculations. On its initialization the C++ DLL launches the Java VM via the JNI invocation interface. When the DLL functions are called by the application, they forward the calls to Java objects inside the Java VM, again via JNI invocation interface.
This works well, but I have encountered a weird error.
From Java I open a JFrame containing a JTextArea as small console for debug output messages. If I turn output to this debug console off (my printToConsole routine checks whether a boolean flag is set), the string concatenation operator may lead to a crash of the Java VM.
For example, if in one of the Java functions called from the
DLL via JNI invocation interface the following is the first statement,
it leads to a crash of the Java VM and the application that loaded the C++ proxy DLL.
String test=""+Math.random(); // String test not used later
Interestingly, if I comment this statement out, the Java code works fine WITHOUT any crash. I've already thought about potential races and synchronization issues in my code, but I don't see where this is the case. And the string concatenation error fails as well, if I insert sleep() statements in front of it and at other places in the code. However, if I turn on log messages printed to my JFrame debug console (containing a JTextArea), the String concatenation works without problems.
So maybe the JNI interface has a bug and affects the Java VM; I don't see where my JNI code is wrong.
One problem is that I do not get any stdout output, as the C++ proxy DLL is loaded by the Windows application, even if I start the Windows application from the DOS command line (under Windows).
Does anyone know how to use the error reporting mechanism?
http://java.sun.com/j2se/1.4.2/docs/guide/vm/error-handling.html
Is it possible that the JVM, when it crashes, writes debug information about the crash into a file instead of stdout/stderr?
My C++ proxy DLL was compiled in debug mode, but the commercial application (which loaded the DLL) is very likely not.
I do not know hot to find the reason why the String concatenation fails inside the Java function called from the C++ DLL via JNI.

Yes, I've initially thought about errors in the C++ code too. But the C++ code is actually very simple and short. It doesn't allocate anything on the C++ side. It allocates a couple of ByteBuffers inside the Java VM however via JNI invocation interface calls of env->NewDirectByteBuffer(). The native memory regions accessed via the ByteBuffers are allocated not by my own C++ code, but by the program that calls my DLL (the program is Metastock).
The interesting thing is that everything works fine if output to my debug console is enabled, which means that in the Java print routine getConsoleLoggingState() returns true and text is appended to the jTextArea.
static synchronized void print(String str)
{ MetaStockMonitor mMon=getInstance();
if ( mMon.getFileLoggingState() && mMon.logFileWriter!=null) {
mMon.logFileWriter.print(str);
mMon.logFileWriter.flush();
if ( mMon.getConsoleLoggingState() ) {
mMon.jTextArea1.append(str);
Only if output to the JTextArea is turned off (ie. getConsoleLoggingState()==false), the crash happens when the FIRST statement in the Java routine called via JNI invocation interface is a (useless) String concatenation operation, as described above.
String test=""+Math.random(); // String test not used later
Moreover, the crash happens BEFORE the allocated ByteBuffer objects are accessed in the Java code. But again, if console output is turned on, it works stable. If console output is turned off, it works when the (useless) String concatenation operation is removed in the Java routine called from C++.
I've already thought about potential races (regarding multiple threads), but this can be ruled out in my case. It almost appears as if the JVM can have problems when called by the invocation interface (I tested it with Java 1.4.2 b28).
All the calls between C++ and Java go ALWAYS in the direction from C++ code to Java. Unfortunately, there is no special JRE version with extensive logging capabilities to facilitate debugging. And the problem is not easily reproducible either.

How to use the Calculated attibute in view object

Hi,
I have a view object query with the calculated attribute name as 'TRANCODE' in the below sql.This query works for the initial page loading.
After the page gets loaded, there is a search section in the same page at the top.
Here i will have to build the whereclause to the same query and retrieve the values.
i am using jDeveloper 10.1.3.1, with adf and jHeadstart.
Can some one tell as how to use the calculated attribute TRANCODE in whereclause?
SELECT /*+ first_rows(10) */
BatchCntl.FILE_CNTL_ID,
CASE WHEN chk_bit(Entry.ENTRY_FLAGS, 2)='Y' OR Entry.ENTRY_SUBSTATUS = 'D' OR Entry.ENTRY_SUBSTATUS = 'J'

Let's say your application module is com.yourcompany.someapp.services.MyService, and let's say you authored a method like the following in the MyServiceImpl.java file:
public void doSomething(int i, String s) {
}and you exposed this AM custom method using the AM editor.
BC4J design time will automatically create you the com.yourcompany.someapp.services.common.MyService interface that will look like this if you go look at the source code:
package com.yourcompany.someapp.services.common;
import oracle.jbo.ApplicationModule;
public interface MyService extends ApplicationModule {
public void doSomething(int i, String s);
}To use your custom method from a client, just cast your ApplicationModule to your custom interface like this:
import com.yourcompany.someapp.services.common.MyService;
MyService mySvc = (MyService)yourAM;
mySvc.doSomething(1,"foo");

How to use the CMS functionality in Sun Portal Server 7.2

Hi All,
How to use the CMS functionality using the ccd.war(Portlet) which is available in the library as i could add it to my channel but not able to show the functionality as it is showing the error msg "You are currently not logged in. Please login." should I create userid and there respective roles inorder to use the CMS functionality.
Has any one used this as I could this in glass fish server.
Any Input is appreciated.
Thanks & regards
Srikanth

Have a look at the "*Roles*" section of the portal server 7.2 content management system guide
http://docs.sun.com/source/820-4275/index.html . You can also look at [project mirage|https://mirage.dev.java.net] for some screencasts
Alternatively,
1. ccd.war has 3 portlets in it:
(a) custom content definition portlet
(b) custom content portlet
(c) workflow portlet
2. Inorder to work with these portlets, user needs to be in anyone of the below roles:
(a)Consumer (b) Editor (c) Approver (d) Administrator (e) Submitter (f) Contributor (g) Publisher
3. By default ccd.war gets deployed using a default roles file (/var/opt/SUNWportal/tmp/ccd.roles.properties)
Note: In windows, you may not find this file
4. Access the portlets as a user in any of the role mentioned in the ccd.roles.properties
(OR)
you can use a new roles file which has mapping to your custom roles. For this , undeploy existing ccd.war and deploy again with a new roles.properties file
Hope this helps!
