Java Junk

For almost a week now I have been struggling to get my Powerbook G4 (Aluminum) running Tiger OSX 4.10 to run properly afgter a fatal crash that required running a complete clean reinstall.
It's difficult to remember where it all started. I first noticed problems about 2 months ago when I tried to use an iSweet cam with iChat. I got no video output, and since a different camera worked, I eventually decided it was a compatibility issue with the 4.10 upgrade I had recently installed, so I wanted to go back to 4.7. I did an archived reinstall, and things worked fairly well...except I was unable to download new files from the internet, especially using software updater. Once things stablised a bit I thought I would try to put 4.10 back on...but it wouldn't download. Some "codex" error...or "version not signed by Apple"...even though I always go through the Apple download site for my upgrades.
So, for several weeks I continued to try to patch things together, but I never did really get it running smoothly again. Then 5 days ago, all **** broke loose. I was running 10.4.10 with Firefox (the browser I have been using) and I went to a sight I have been to often (Yahoo! Bridge) and repeatedly was unable to log on. The browser would freeze, such that I would have to "force quit" it everytime it got to this one point where you have to click past the advertisement. I notices a progress message about JS2E 5.yimg.
I tried several things. Including reinstalling java (threw away receipts). I tried running "Disk Warrior" (a maintenance software that has always worked well in the past) and it got to this point in the scan where it said "overlapping files found" and then refused to budge. I even tried restarting it...nothing. I took it out and tried running the computer...(Blue screen with progress bar making no progress). That's when I decided I had no choice but to run a clean install.
That went fine. So, the first thing I did was upgrade all the OS things first. It didn't progress smoothly, but I did eventually get them on. The camera works in iChat but I couldn't for the life of me get ANY browser to open the Yahoo! Bridge site. I even tried using an alternate ID. So I decided the problem must be systemic. I threw away all things java, and ran system updater to reinstall all things java. Again, not smooth, but I got it all on...restarting after each install. And now I'm faced with the damnedest thing...I have never seen such a thing.
My HD icon is just a grey box on the desktop (no stethoscope or anything). When I open any folder, the icons for the files are there, but as soon as I select on, it disappears, never to return. The dock icons are there, and in all other ways the computer seems to be running ok. I tried restarting and running the disk utility (and Disk Warrior), but neither of those things helped.
Does anyone know how to get my icons back? And...is it indicative of a deeper problem? Apple just changed out this logic board a year ago.

Thank-you HenryG4.

SQL Insert Error - Please help. RESOLVED

I have a page with several VOs and search options. One of the search options is a list of Emp IDs which (when one is selected and user clicks 'search') results in an editable table of profiles for that Emp Id.
I have in the Footer of the results table an input field and a button 'add' bound to a method that takes two params and inserts a 'new' profile for the searched Emp Id and the value entered in the input field.
When I enter a value and click 'add' I get the following:
JBO-29000: Unexpected exception caught: oracle.jbo.DMLConstraintException, msg=JBO-26048: Constraint "BADGE_ACCESS_EMP_FK" violated during post operation:"Insert" using SQL Statement "BEGIN INSERT INTO BADGE_ACCESS(EMPLOYEE_ID,BADGE,ROW_ID) VALUES (?,?,?) RETURNING ROW_ID INTO ?; END;".
JBO-26048: Constraint "BADGE_ACCESS_EMP_FK" violated during post operation:"Insert" using SQL Statement "BEGIN INSERT INTO BADGE_ACCESS(EMPLOYEE_ID,BADGE,ROW_ID) VALUES (?,?,?) RETURNING ROW_ID INTO ?; END;".
ORA-02291: integrity constraint (HR.BADGE_ACCESS_EMP_FK) violated - parent key not found ORA-06512: at line 1
My Emp table is simple - just an ID, First and Last names with ID as PK. My profile table (called Badge_Access) has the EmpId as FK and it's own PK set by a DBSequence. The other column in Badge_Access is for the input value (number).
I do not know how to debug in JDeveloper such that I can see the values that are being passed to the method. My 'add' button method is:
public void createBadgeAccess(Number empId, Number badge) {
BadgeAccessImpl ba = (BadgeAccessImpl)getDBTransaction().createEntityInstance(BadgeAccessImpl.getDefinitionObject(), null);
ba.setEmployeeId(empId);
ba.setBadge(badge);
getDBTransaction().commit();
I have the 'value' of the empId param = ${bindings.AccessByEmployeeEmployeeId.inputValue}
This is the selectOneChoice field the user uses to search...
and the 'value' of the badge param = ${bindings.Badge.inputValue}
This is the input field the user fills in before clicking 'add'...
The values I think I am passing are empId=106 and badge=102 - both are valid & the 'parent key' 106 is valid...
any help will be greatly appreciated!!! Thanks

I found a Tip that described what was happening.

Wrap some try/catch around the statements instead of trying to decipher the Java junk. Could be a problem in the PS, could be a number of things. At least figure where in the application the error takes place.

Access properties outside executable jar

OK I have spent long and hard trying to figure out this jar system. I even created my little junk test
See executable http://homepage.ntlworld.com/jeff.burden/paulb/java/junk.jar (source code is in junk.jar)
My problem is this
/pjb/deployed/prog/program.jar
/pjb/deployed/prog/
/pjb/deployed/prog/res/test.jar
/pjb/deployed/prog/props/mainConfig.propertiesmyprogram.jar has the following in manifest
"class-path: res/ props/" test.jar contains
pjb/apps/progsub/res/myfirst.class
pjb/apps/progsub/res/myfirstConfig.properties
the program.jar can read the mainConfig.properties, but it cant read the test.jar's myfirstConfig.properties
    private static String getResource(String fc, String key, Locale lc) {
            String out = java.util.ResourceBundle.getBundle(fc,lc).getString(key);
            return out;
    String moduleName = getResource("pjb.apps.progsub.res.myfirstConfig","greeting",eng);myfirstConfig.properties contains
greeting=Hi from inside a Jar
I dont want to add test.jar to the class-path as I want to add more jar files
What am i doing wrong? I thought if i specifiy a directory in the classpath it will pick up all the resources in it.

The program works when it is not in a deployed environment. That is
When im developying in NetBeans I mount the directories required for the sourcode to run
Everything works fine.
But when i try and delopy the stuff as described above, i get them anoying
MissingResourceException Can't find bundle for base name pjb.apps.progsub.res.myfirstConfig, locale en

Fastest Way to Load Text Files Containing Thousands of Words

Hi, can anyone give me suggestions for fast loading of files containing many bytes in the form of a single word on a different line. The average file size is 45 kb. I'm currently splitting the words into separate files each containing 4000 words a piece. I use a different thread to read each file and then add all of the words into a single vector, formed by joining the vectors of each reader thread. Any suggestions for speeding up the process? (Currently, it takes about 30 seconds to load 52,000 words). My OS is Windows2000

Something seems wrong. There is no way that what you describe should take anywhere close to that amount of time, unless the computer is a constraint. I created a file of 56,000 lines, each line consisted of the byte string "abcdefgh" plus a \r\n,
for a total of 10 bytes per line - a total file size of 560,000 bytes (547 kb)
The following program read the file, created an ArrayList, and added the 56,000 lines to the list in less than 1 second, about what I expected. You might want to run it and see what you get.
import java.io.*;
import java.util.*;
class Zxin
    public static void main(String[] args)
        throws IOException
        FileInputStream fis = new FileInputStream(
            "C:/Documents and Settings/Chuck/My Documents/Java/junk/word.txt");
        InputStreamReader isr = new InputStreamReader(fis);
        BufferedReader br = new BufferedReader(isr);
        List<String> list = new ArrayList<String>();
        String data;
        while ((data = br.readLine()) != null)
            list.add(data);
        System.out.println("The list contains " + list.size() + " entries");
        System.out.println("The first entry in the list is: " + list.get(0));
        br.close();
}It printed these 2 lines:
The list contains 56000 entries
The first entry in the list is: abcdefgh

Junk characters in java

Hi,
How to block the junk characters in java when csv file uploading.
Thanks

Not possible. You can only do it during processing the upload at the server side. If you also don´t know how to do that, then you need to be more specific about the problem before I could give an extended answer. For instance, you should elaborate "junk" here. At least, are you familiar with character encodings and the sense of it?

Cannot convert ÿØÿà of type class java.lang.String to class BFileDomain.

Hi All,
I am using Jdeveloper 11.1.2.3.0.
I have a scenario of making an ADF page where I have a IMAGE field to show on the page. So,I have a table called "PRODUCT" with fields called photo with BFILE type. Now when I the data i have inserted using the DML command and i can see the path at the backend.
However,when i am runnig my ADF page in the Filed called "PHOTO" I can only see a junk character stating 'yoyo'.
When I click on it, it says ERROR "Cannot convert ÿØÿà of type class java.lang.String to class oracle.jbo.domain.BFileDomain".
Your help will be appreciated ASAP.

Shahnawaz

Hi,
did you show the id-value in the user interface as a input-component, and did the input-component include a converter?
If yes, show the id as output-text and remove any existing converter-components.
Best Regards

Need help on returning arrays from C++ to Java

Hi all, I hava a C++ application that contains a method that will return a float array to Java. I was able to write the Java Code, the JNI code to call the C++ method and compile them successfully. However on calling the native method from Java, the data in the array returned was not what I want. Please look through my code and see what is wrong with it.
My Java Code:
public native float[] Statistics(int inputKey); // This is the native method
public float[] Stats(int k){ //Java method to call the native method so that I can use it in a Bean for a JSP.
inputKey = k;
float[] p = new float[4];
p = Statistics(inputKey);
return p;
For this native method, an integer is passed from Java to the native side and the native method will use this integer to generate a float array size of 4 and populate it with data and return it back to Java.
My JNI code
extern "C"
JNIEXPORT jfloatArray JNICALL
Java_com_jspsmart_upload_FinalWaterMark_Statistics(JNIEnv *env, jobject obj, jint inputKey)
     jfloatArray floatArray = env->NewFloatArray(4); //This creates a new Java floatArray to store the C++ array
     CWatermarker2App p; // This is the C++ class to be used
     jfloat *stats = p.OnWatermarkStatistics(inputKey) // The C++ method returns a float pointer for an array of size 4
     env->SetFloatArrayRegion(floatArray, 0 , 4 , stats); //storing the C++ float array into the Java float Array
     return floatArray; // return the Array to Java
In this example, I should have the data returned as [4952.0 2529.0 1706.0 33.6] in the array.
But i am getting junk instead like 2.53E-23, 1.402E-15 etc..
Is this a type conversion mistake?
Please help!

The first thing I notice - probably not the problem - is the line defining p. There is no reason to define this as an array of size 4, because the return from the native method is going to wipe that definition, replacing it with the return value of the native method. Alternatives:
1. float[] p = null.
2. float[] p = Statistics(inputKey);
3. return Statistics(k);

hi
you have to change the config.xml to allow the server accept relay mails from your host machine from which you are sendign the mail ...
ie
change
<mailet match="RemoteAddrNotInNetwork=127.0.0.1" class="ToProcessor">
<processor> relay-denied </processor>
<notice>550 - Requested action not taken: relaying denied</notice>
</mailet>
add few more ips (your network / subnet ip)
so that it accpets mails from that machine to be relayed ...
you can also change the smtp autheriZation part and do that ...
any one is enough ..

One thread is enough.

You could have bumped it instead. Also, you still just posted a junk of unformatted stuff. Furthermore, for HttpClient support ask at an HttpClient mailing list of rorum.

How to submit a HTTP Request from a Java Program

I am working on an web based application where in I need to submit the HttpRequest through a Java Program and not through browser. Moreover my intent is just to submit the HttpRequest. I donot want to wait for the response to come back. I have used the URL Connection class to do the same and I am trying to post this request. The contents of the methods that I am using are as below:-
public void doPost(URL url, String inputXMLString) throws IOException
          //Create URLConnection based on the passed URL
          URLConnection connection = url.openConnection();
          connection.setDoOutput(true);
          connection.setDoInput(false);
          connection.setUseCaches(false);
          connection.setAllowUserInteraction(false);
          connection.setRequestProperty("Content-type", "application/x-www-form-
urlencoded");
          //Get the Connection's output stream and write the request to it.
          PrintWriter out = new PrintWriter(connection.getOutputStream());
          out.print("&ena-request-input=" + URLEncoder.encode(inputXMLString));
          out.flush();
          out.close();
Call to the above method does not invoke the URL I am intending to submit the request at.
Can anybody give me the clue....................................................?

I agree with the advice to launch a new thread to read and ignore the response. I don't think you should have to do it to make it work, but it's worth trying for two reasons:
1) If it turns out it does make it work, well, then either you can leave it that way, or use that as a clue to help figure out how to make it work the way you want.
2) There may be an error message there that will give you an idea why it's not working.
When you say it's not invoking the servlet, what does that mean, and how do you know? Is it just that the final results aren't being seen? Put a bunch of logging statements in the servlet. It could be that it's getting hit, but you're corrupting the string you're building, or sending some extra junk that it can't handle. Spit out a log statement from the start of doPost, to see if it's even getting there. Then log the parameter. Enclose the output in quotes or braces or something to make sure there's not extra junk. I've had XML docs not parse because there was a blank line at the beginning.
If it works in the browser but not from your standalone app, then you need to have the servlet tell what difference it sees in the two cases. Print out headers, other params, everything you can think of.
Re-read the docs for URL, HttpURL, whatever, to make sure you're doing all the right steps in the right order. Make a servlet that just takes a single, simple param=value via POST and see if you can get that to work.

Error in weblogic7.0 :java.security.NoSuchAlgorithmException:

Hi All
thanks in advance.
i am facing a peculiar problem while using SunJce provider
i have some classes to encrypt& decrypt some information using
DeffieHellman protocol.
Problem 1
while i am running those classes in command prompts
some time it gives me correct results where as other time during decryption i am unable to get the plaintext (i am getting some junk character),where as some time it gives me Badpadding exception
I am using JDK1.3 which comes with weblogic and jce1.2.2
for classpath and path setting
set path=D:\bea\jdk131_03\bin
set classpath=%classpath%; D:\bea\jdk131_03\jre\lib\ext\ jce1_2_2.jar

Badpadding Exception and NosuchAlogorithm exception in weblogic
Thanks
And regards
Arati

replace all calls of getBytes() and new String(text) with the versions where you can state a charset: getBytes(charset), new String(text, charset). i use "iso-8859-1" as the charset.
this should at least fix your "Badpadding exception" problem (it did fix it for me).

Help - Safari won't open it just bounces, installed Java 2012-04 but java preferences is not picking it up

I''m new to the MacBook, I've got a late 2007 model running Lion 10.7. I installed iLife and removed some junk (software installed from previous user that was not properly licensed) then tried to open Safari. The icon just bounced and I got the error Safari quit unexpectedly. I downloaded the new Java that should fix the Flashback Malware issue (I did this because in the log it stated that garbage collection was turned off) onto my thumb drive, installed it on the Mac, opened Java Preferences and it only lists the 32 and 64 bit Java SE6. So now what???

Right or control click the Safari app in the Applications folder then click Get Info.
For Version. If you see 5.1.6 or 5.1.7 updating to Safari 6 may help. Apple has not posted a standalone Safari 6 intaller but there is a workaround.
Click here > Safari Quits Every Time Opened: Apple Support Communities
Then click the link posted by: gregoryfromcork
That will automatically download this file > Safari6Lion.pkg.download
Now quit Safari.
Go to your Downloads folder and double click that file and follow the instructions for installing.
Then restart your Mac, try Safari.

Error while sending mail when using Java Mail API

Hi Experts,
I am trying to execute a webdynpro application which uses the Java Mail API to send emails. The exception that I get on executing the application is :
Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
Can anybody please help me sort out the issue.
Regards
Abdullah

Hi,
Usually one get this error if the SMTP server is configured not to relay mails (a security measure) or the SMTP server need the mail to be sent from a trusted IP or with proper authentication. Some SMTP servers are configured to block junk mails.
Pls check with your mail server administrator.

URGENT:- Running a batch file from java program

Author: pkanury
I am trying to execute a batch file from my java program using RunTime and Process . It can execute any dos command except for a batch file. Can anyone throw
some light ?? My code looks like this .....
cmd = "command.com /c X:\\grits\\scripts\\test.bat"; Runtime rt = Runtime.getRuntime(); Process p = rt.exec(cmd);
The weird part is that p.waitFor() returns a status of 0 implying that the cmd has been executed successfully. But that is not the case. And my batch file is as simple as - type "ADADA" > junk.txt
Any help would be appreciated.

I think it should work when you use a String[] array
instead of a single String:
String[] cmd = { "command.com", "/C", "D:\\batch\\do.bat" };
Note: If the batchfile creates any output (i.e. files),
they will be stored in the directory of the application
which calls the batch file, not in d:\batch\...

Very simple Java AWT Frame resize question

In the following code, I create an awt Frame. Unfortunately, when I run the resulting Java application (on Windows) and use the mouse to resize the window, none of the Frame's resize/setSize methods get called. Can anyone explain why this is?
Thanks
Greg
import java.awt.* ;
public class Junk extends Frame {
public static void main (String args[])
Junk j = new Junk ();
j.show ();
public void resize(Dimension arg0)
super.resize(arg0);
public void resize(int arg0, int arg1)
super.resize(arg0, arg1);
public void setSize(Dimension arg0)
super.setSize(arg0);
public void setSize(int arg0, int arg1)
super.setSize(arg0, arg1);
}

When the user resizes the frame with the mouse, the resizing action probably happens entirely on the Frame's peer, without the java.awt.Frame getting involved at all. setSize() and [deprecated] resize() allow an application to programmatically change the size of a Frame, but the Frame just passes the new size to its peer.
If you want to detect when your Frame has been resized, use addComponentListener to register a component listener on the Frame, and then put your code in the componentResized method of the listener.
