Does Jdeveloper 9iRc2 support JDK 1.4?
I am trying to use JDK 1.4 but I keep getting "Could Not Initialize the Java Virtual Machine"
Any Suggestions?
Thanks,
Mike Johnson

Hey Mike,
     I'm not seeing your same error, but the HotSpot server JVM (JDK 1.3) is
core dumping for us as well. WebLogic 5.1 sp6 on Solaris 2.6. We get
this:
# HotSpot Virtual Machine Error, Unexpected Signal 11
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi
# Error ID: 4F533F534F4C415249530E435050079A 01
# Problematic Thread: prio=5 tid=0x1049b0 nid=0xb runnable
     As you can see, we're not getting the OutOfMemoryError you're seeing,
the JVM just core dumps and dies! This happened in our production
environment and we had to go back to using JDK 1.2.1_04, which is an
extremely solid JVM.
     It just stinks because the performance of the HotSpot JVM was
UNBELIEVABLE!! Our app flew with it.... :-(
     I voted for your bug below on the bug parade. Let's hope it gets fixed
fast.

JDK 1.3 crashing with WLS 5.1 on Solaris 2.6. It occurs when the 'PermGeneration' memory reaches
it's maximum size. You need to load a lot of classes - EJBs/JSPs to make it happen.
Does anyone else have this problem?

How to install and configure WebLogic 10.3 to use 64-bit JDK?

Hi,
Is there a preferred/supported way to configure WebLogic to use the 64-bit JRockit that comes with JRockit Mission Control?
I can't find any official documentation about how to configure WebLogic to use a 64-bit JDK. From other forum posts I can tell we need to use the 64-bit JRockit that is bundled with JRockit Mission Control (available at [http://www.oracle.com/technology/software/products/jrockit/index.html]) but then we are kind of stuck - the configure script which let me select a JDK for a domain doesn't seem to let me re-configure an existing domain, and I can't find anything within the admin console that would let me set the JDK to use.
I was able to rename the existing jrockit_160_05 directory to e.g. jrockit_160_05_original and then rename the jrmc directory to "jrockit_160_05", effectively taking the place of the JDK being used but this seemed like a bad way to do it. I also found via Google this page: [http://java.sodeso.nl/application-servers/bea-weblogic/how-can-i-change-the-jdk-installation-that-weblogic-uses] which basically says to modify the JAVA_HOME environment variable in the start scripts, but this seems like the same thing.
With the plethora of products and the different ways they are bundled, combined with all the documentation about everything, I thought I would find something but I keep coming up blank. Does anyone have suggestions or pointers?
Thanks,
KaJun

Make sure your environment configuration is supported here:
http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html
Then, you need to have the correct 64bit JDK installed. Sounds like you have done that.
Then download and run the generic platform installer as described here with your 64bit supported JDK:
http://download.oracle.com/docs/cd/E12839_01/doc.1111/e14142/start.htm#i1077535
Notice how the link you post has the generic installer for all the 64bit JVM rows, but the other installer for the 32bit JVMs on the 64bit OS?

Paint performance with JScrollPane very slow in jdk 1.4?

I got a simple program that overrides paintComponent on a JPanel. Then draws lots of lines, rectangles and some strings. The panel is then added to a scrollpane.
The scrolling is very smooth in java 1.3.1, but very slow in 1.4.2
the paintComponent takes between 16ms and 30ms with java 1.3.1 but 70-200ms with java 1.4.2.
I tried turning of antialising etc.. but no help. Whats the "improvement" they made in jdk 1.4?

Ok I made a simple example, which draws around 5000 elements.
Sourcecode is here: http://www.mcmadsen.dk/files/ScrollPaneTest.java
I did several testruns on java 1.4.2 and java 1.3.1, heres the "avarage" result:
Java 1.4.2:
Current: 140ms High: 203ms Avg: 144ms Low: 125ms
Java 1.3.1:
Current: 62ms High: 219ms Avg: 68ms Low: 47ms
The paintComponent() looks like this:
public void paintComponent(Graphics g)
super.paintComponent(g);
long offset=System.currentTimeMillis();
PaintElement paintElementTmp;
for(int i=0;i<paintElements.size();i++)
paintElementTmp=(PaintElement)paintElements.elementAt(i);
g.setColor(paintElementTmp.getBackground());
g.fillRect(paintElementTmp.getX(),paintElementTmp.getY(),paintElementTmp.getWidth(),paintElementTmp.getHeight());
g.setColor(paintElementTmp.getForeground());
g.drawString(paintElementTmp.getText(),paintElementTmp.getX(),paintElementTmp.getY());
long done=System.currentTimeMillis();
long current=done-offset;
sum+=current;
if(current>high)high=current;
if(low>current)low=current;
count++;
System.out.println("Current: "+current+"ms High: "+high+"ms Avg: "+(sum/count)+"ms Low: "+low+"ms");
I tried all the renderinghints, but no difference (from the default settings). Also the scrolling is very slow and stops all the time in java 1.4.
Any ideas on how to get java 1.4 to perform as java 1.3.1?
Thanks

JAXP 1.4 in JDK 1.5? javax.xml.stream.FactoryFinder$ConfigurationError

hello,
i'm forced to develop in jdk 1.5 and need to use package javax.xml.stream (StAX), which is not included in jaxp1.3 (in jdk 5), so there is a need to somehow integrate jaxp 1.4 to jdk5.
first thing i've tried was getting jaxp 1.4 src and include a buildpath to my project to it. problem is, that javax.xml.stream.XMLOutputFactory.newInstance() throws exception javax.xml.stream.FactoryFinder$ConfigurationError: Provider com.sun.xml.internal.stream.XMLOutputFactoryImpl not found
thanks in advance

BufferedImage creation slow in JDK 1.4.2

Hi,
The creation of BufferedImage of size 400x400 takes 156ms in JDK1.4.2. It used to take less than 10ms in JDK1.3.1.
Image image = new BufferedImage(400, 400, BufferedImage.TYPE_INT_ARGB);
In JDK1.4.2, for sizes 363x363 and above, it takes 156ms and
for sizes under 363x363, it takes close to 0ms.
Is this a bug in JDK 1.4.2? I noticed similar behavior in JDK1.5 also.
My machine configuration:
Windows XP, 512MB Ram, 1.7GHz
Thanks,
Bindu

The arg type of the setter and the return type of the getter must match up or you'll get this exception.

Problems with Adler32 class in JDK 1.5 (not tried 1.6)

When I use the java.util.zip.Adler32-class for generating Adler32-checksums, I found a couple of strange problems. When the total filesize (generating checksums of several files with the same checksum-object, using reset() in between) is 31999 bytes or greater, it gives pseudorandom output for the first file that exceeds the 31999 bytes. By running the test-program several times in a row, it seems like the output changes every second, as if random data was generated with the second counter as a seed. All the other checksums seem correct, and they do not change. A workaround that works for a series of only small files is to create a new Adler32-object for every file that needs its checksum generated, but that proves itself insufficient when a single file exceeds 31998 bytes of size (31999 or above).
I've tried different inputstreams and various methods of using the update(xx)-functions of the Adler32, but I always get the same results. Is this a known bug (Note: JDK 1.5, not 1.6)? Or am I doing something obviously wrong? Example source code can be provided if necessary.

R,
I'm disappointed to see that you haven't received any replies to this. I am experiencing a very similar problem. What I have noticed is that the problem occurs when the combo-box is forced to be heavy-weight (meaning it has to draw itself outside the bounds of the window). In those cases, I can never pick a different value from the combo-box in the table. The exact same app run under 1.3.1 does not have any problems. Further, combo-boxes not in table views do not seem to have any problems even when they are heavy-weight.

Reading private key: works in jdk 1.5, but throws exception in 1.4

Hello,
I am trying to read an RSA private key from a file. I am using the following code snippet:
KeySpec spec = new RSAPrivateKeySpec(modulus, pExp);
KeyFactory factory = KeyFactory.getInstance("RSA");
PrivateKey key = factory.generatePrivate(spec);
This runs perfectly fine under jdk 1.5 on keys I generate with OpenSSL. However, if I recompile and run under jdk 1.4, I get the following exception:
java.security.spec.InvalidKeySpecException: Unknown key spec.
     at com.sun.net.ssl.internal.ssl.JS_KeyFactory.engineGeneratePrivate(DashoA6275)
     at com.sun.net.ssl.internal.ssl.JSA_RSAKeyFactory.engineGeneratePrivate(DashoA6275)
     at java.security.KeyFactory.generatePrivate(KeyFactory.java:237)
I have also tried using RSAPrivateCrtKeySpec but I get the same error. Can anyone shed some light on what is going on?
Thank you.

'Unlimited Strength Jurisdiction Policy Files 1.4' Could be the solution.
I had a similar problem with java 1.4 and those files do the work.
... finally the problem was that the password that protectd the keystore had 7 characters, using one of 5 characters works ok...

Running flash in JDK 1.7

Hi,
In my java application I use the jdic.jar, jdic.dll, files are used to load flash files in Browser through my java application.
I include the flash in the application path use the following function with the URL pointing to the correct location
webBrowser.setURL(url);
This worked fine with JDK 1.6, after upgrading to JDK1.7 I am facing a strange problem. The browser is loading .swf file which has a tree structure. The left click button works only once, after which it doesn’t work. This is the same case with all the different .swf files we have.
In other words I am able to navigate to the immediate next Flash slide, but no further.
Can some one please help?
Thanks

Sry for being this late but I thought I might add..
I found AWTUtilities under com.sun.awt.AWTUtilities if anyone is still wondering. That means it's proprietary and might be removed in the future so using it is not recommended.
Here's one such instance of how it might be used: [http://www.pushing-pixels.org/?p=260]

Works fine in JDK 6.0 but not in jdk 1.5.???????

Hi all,
This code converts english date to japanese date but it is working fine in english only. can any body answer why it is so.
Note : No Comiplation problem in jdk 1.5
This code works fine in JDK 6.0 but not in JDK 1.5, Why.....?
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
        Locale locale = new Locale("ja", "JP", "JP");//locale for Japanese
        Calendar cal = Calendar.getInstance(locale); //japanese calender object
        DateFormat df = DateFormat.getDateInstance(DateFormat.LONG,locale);
        try{
        Date date = sdf.parse("1930/09/27");
            System.out.println(df.format(date));
        }catch(Exception e){
            System.out.println(e.getMessage());
        }

Hi,
If I give the Input date 1930/10/27 (in english), then program must display the date as S5.10.27 (it's japanese date with 'S' indicating ERA)
But this will happpen only when i run the program in JDK 6.0.
In JDK 1.5, for the above input, the output is 1930/10/27 (which is wrong)
Still I don't have compilation and running problems in both. Can anybody expalin why it is so?
I think i tried my best to restate the question.
Thanx

Socket connect slow in JDK 1.5?

We recently began testing our Java Swing application with JDK 1.5, and we noticed that socket.connect()
calls are taking several seconds to return, when before in 1.4 the calls returned immediately.
Here is some sample code:
Socket sock = new Socket();
InetSocketAddress sockAddr = new InetSocketAddress(inAddress, portNum);
sock.connect(sockAddr, 2000);
What could be wrong? I've debugged the code and verified inAddress is an IP address,
not a hostname.

Here is the list of enhancements in JDK1.5.
http://java.sun.com/j2se/1.5.0/docs/guide/net/enhancements-1.5.0.html
I wonder if any of them are having some effect in the slow connection.
There are some network properties that you can tweak with. Did you try them?

Very Urgent Unable to Launch Application using Web Start using JDK 1.4.2

Hi all
I am very serious issue i have ejb client swing application that uses
RMI to contact a session bean deployed in JBoss now i want the client app to be installed in the client machine using web start . Also i understand i require security permission to access network resources. so i have signed all the JAR files with same certificate created using self certificate avialiable in JDK by default also in the JNLP file in have included the following tag
<security>
<all-permissions/>
</security>
Now when I launch my application using Web start it gives an error that " Unsigned application is trying to access local resources"
I unable to understand what could be the problem . Please help me with the steps to be followed where in client should be able to RMI call to the server
Thanks in Advance
Naveen

You may have tried this already, but you might have to sign the jars via command line, outside any export process from your IDE.
$ jarsigner {filename}.jar {key from keystore}
I also had problems using webstart and RMI through an RCP

Application crashes when using JNI with Jdk 1,2, 1.3 and 1.4

Hi!
I have this application that has a GUI written in Java and a file parser written in C. JNI is used to connect these parts together. The problem is that the application only works when I am using jdk 1.1.8 but not when using jdk1.2, jdk1.3 or jdk1.4. I am running the application on a Solaris 8 machine.
I have not written the application myself but I am going to be working with it from now on. But I have today little knowledge with JNI and I have tried different approaches to solve the problem. For example I have tried to used DDD together with GDB to find out what the problem is but with no luck. When I run the application using jdk1.4 I get the following error when the JVM crashes:
An unexpected exception has been detected in native code outside the VM.

From this information I think that the problem should be in the native method setDebug. But I have tried to set a breakpoint at the beginning of that function in the C part but with no luck. The application crashes before it reaches that position in the C file.
What could possibly go wrong between the setDebug function in the C part and the function call in the Java part?
When using GDB, GDB cannot figure out what is wrong it just returns a hex address, no function name.
I would really appreciate some help. I have tried everything that I can come up with!
Best regards
Lars

I have figured out that the application fails on its first call to the native methods.
So I have this Bitmap class that contains all the native calls and it is defined shortly as follow:
public class Bitmap {
static {
System.loadLibrary("BitmapImpl");
native void setDebug(int debuglevel, int statistics);
There are many more native methods defined in Bitmap, but I only show the setDebug method because that is the first one that is executed and also the one that immediately fails.
My setDebug C function is defined as follow in BitmapImpl.c
#include <time.h>
#include <stdio.h>
#include <limits.h>
#include <fcntl.h>
#include <jni.h>
#include <math.h>
#include <errno.h>
#include "Bitmap.h"
#include "data.h"
jint debug = 0;
jint statistics = 1;
JNIEXPORT void JNICALL Java_Bitmap_setDebug
(JNIEnv *jenv, jobject jo, jint d, jint s)
debug = d;
statistics = s;
My libBitmapImpl.so file is compiled using the following Makefile and using GNU gcc:
JAVAPATH=$(JAVAINCLUDEPATH)
LMACRO=-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DSOLARIS
CSOURCE=BitmapImpl.c
all:
gcc -O3 -G $(LMACRO) -I$(JAVAPATH) -I$(JAVAPATH)/solaris \
$(CSOURCE) -o libBitmapImpl.so
It is still a total mystory why the application fails. I have tried it on a RedHat Linux machine and there it works fine. But not on Solaris. Only if I use the jdk1.1.8 but not a later one.
Would really appreiciate some help!
Best regards
Lars

We are using Entrust certificate and we already put cacerts file from jdk1.4 to jdk1.2.1 in jdk/jre/lib/security.
This application was working till we upgraded version from 1.3.1 to 1.4.1.
Is this is problem of 1.4.1 and how do we resolve this?
Small code that will help is as follows
//Dynamic registration of SunJSSE provider
System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
System.setProperty("ssl.SocketFactory.provider", "com.sun.net.ssl.internal.ssl.Provider");
//Create a URL object from the sURL String representation.
uRemoteURL = new URL(sURL);
//Get a connection to the remote object referred to by the URL
ucConn = uRemoteURL.openConnection();
//Set the DoOutput flag to true to use the URL connection for output
ucConn.setDoOutput(true);
ucConn.setRequestProperty("Pragma", "no-cache");
oosToWrite = new ObjectOutputStream(ucConn.getOutputStream());
//Write sInputString to the OutputStream which will be read from the remote servlet
oosToWrite.writeObject(sInputString);
oosToWrite.flush();
oosToWrite.close();
ucConn.connect();
System.out.println("Connection " + ucConn.toString());
if(ucConn==null)
System.out.println("Connection is Null");
System.out.println("getInputStream " + ucConn.getInputStream());
if(ucConn.getInputStream()==null)
System.out.println("ucConn.getInputStream() is Null");
// Read the string object from the InputStream and return
oisToRead = new ObjectInputStream(ucConn.getInputStream());
Object oReadObject = oisToRead.readObject();
sOutputString = oReadObject.toString();
oisToRead.close();
return (sOutputString);

Basically ArrayStoreException comes :
Indicate that an attempt has been made to store the wrong type of object into an array of objects.
But in jdk1.4.1 it is said that
No usage of java.lang.ArrayStoreException
it may be problem of jdk1.4.1 and try to upgrade to 1.4.2

How to set up older version of Java JDK?

I am a Java Developer, and I recently bought a Mac. I also just started working for a Client who is using JDK 1.6.0_23, and this is not going to change. The code fails to compile when running through the latest Java 1.6 JDK, so I REALLY need to download and set up JDK 1.6.0_23. Is this possible? If I can't get this working, I will unfortunately have to use the Windows machine that the Client gave me.
Thanks in advance.

I removed the old program.
I am using this line in my autoexec.bat
path = c:\jdk1.3.1_01\bin
I understand that I don't need to set any classpath. If I am wrong, would this line be correct ?
classpath = %classpath%;c:\jdk1.3.1_0\bin;c:\jdk1.3.1_01\lib\tools.jar

How do I use jdk 1.4 with weblogic 6.1?

Want to use jdk 1.4 features(logging and regular expression) in a weblogic
          application I am developing. How do I get weblogic 6.1 to run with jdk1.4


          This is off topic but see the url below on edocs.
          You will need to make sure that your classpath points to the 1.4 jdk. Changing
          your $JAVA_HOME in the startup script is pretty much it.
          When developing your application, make sure your classpath is set properly .For
          example in the setExamplesSever.sh script you point to the 1.4 jdk.
          FYI This is not yet a supported platform.
