Java and Javaw

Hi all,
My Application is GUI and .Jar file. When I run this file with Javaw (just double click), the appliaction did not show.
However, when I use Java -jar file.jar in Commond Line, the application works property.
Anyone knows what is the problem with Javaw ?
Can the application use System.out.println() in Javaw ?
thanks

How many files are in your JAR? Do you have an optional manifest included in your jar, which specifies the main class of your GUI?
Here's a tip. Look into you JDK Demos and extract the contents of any of the jar files and look at how the manifest was created. Add one to your jar and double-clicking should work fine. ie
jar cvfm0 GUI.jar manifest.mf *.classSecondly, System.out.println does not work with javaw cos the command console will not shown in the first place.

Problem with java and javaw

Hi,
In running the following simple code, I have gotten different results using java and javaw.
public class Test {
public Test() {
public static void main(String[] args) {
int x =4;
System.out.println("The value is "+ ((x > 5)?6.0:4));
System.out.println("The value is "+ ((false)?6.0:4));
System.out.println("The value is "+ ((true)?99:9.9));
Using java, I get the following results:
The value is 4.0
The value is 4.0
The value is 99.0
But using javaw, I get the following results:
The value is 4.0
The value is 4
The value is 99
Any ideas why this is so?
Thanks for any help.

I used JBuilder to run the following code and Jbuilder uses javaw.
By the way, the correct answer is the one using java right?

Java and Javaw hang when I open a file

Hi,
I had to clean install my laptop with XP Pro SP2 so I did, I also installed JDK 6 beta, but I tried this with JDK 5 update 7 as well as JDK 1.4.2_08.
The problem I am experiencing is that when I have a tool (e.g. NetBeans 5 or Jext 5) or I have my own application, when I try to open a file, java or javaw hang, the application is "not responding" according to Windows.
I've tried reinstalling various versions of the JDK but nothing helps. I'm at a loss here and about to reinstall the whole laptop again, but rather not.
Any help would be really appreciated.

Hi Barney,
got it figured out - finally !
If I click on a folder it opens up in its own 1/8 (or so) screen sized window from where I can then access sub folders and files within...and as I close each item down I'm back at the previous place - just as is required...BUT if I click the green 'expand window' button in the top left corner then that particular window AND ALL PREVIOUS ONES will close down as soon as I select a folder or file from it.
In short, the trick is to not expand any window at all...a pain, but can live with it.
Got any ideas as how to stop this happening?
Cheers

Any difference between Java and Javaw, thanks

I can launch my program with java successfully. But on the same setting, javaw failed. WHY?
Thanks

the only difference between java.exe and javaw.exe is that javaw.exe does no (system) output.
see http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/java.html
"The javaw command is identical to java, except that with javaw there is no associated console window. Use javaw when you don't want a command prompt window to appear. The javaw launcher will, however, display a dialog box with error information if a launch fails for some reason. "

What's the difference between the java and javaw?

As the title
Thanks

If you start java code with java.exe, closing the DOS command line window will close the Java application. If you start it with javaw.exe, it will not, but with javaw.exe you have no standard out, meaning printing with System.out.println() will not show up anywhere, because the JVM discards the standard out. If you start a Java application from within Windows directly (Using Start -> Run for example), starting it with java.exe will open a DOS box for the application, starting it with javaw.exe will open no DOS box at all (it will start like a Windows application). As should be clear now, it makes only sense to start Java applications with javaw.exe that have a GUI (graphical user interface), as otehrwise they won't be able to communicate with the user.

Need Help w/ Java and Mozilla on SuSE 8.2

I am completely and totally new to Linux. Until not very long ago the only computer I ever worked with was MS. I'm running SuSE 8.2 Professional.
I used (after much trial and error) the rpm program to remove Mozilla 1.2 (which is installed by default). This is a machine at home so I have root access and regular access. I downloaded Mozilla 1.3 and installed that without a problem. I download j2sdk 1.4.1.02 (I'm pretty sure those are the numbers). I followed the instruction on how to install java and it appears to have worked correctly. I don't know how to test but there is now a directory called j2sdk1.4.1_02 which has several files and directories inside of it (including jre). I also followed the instructions and installed the java web start program.
Anyway, I've searched the forum for information that would explain how to make mozilla work on website that use java. Most of what I read was greek to me. But there was one that said I should copy the libjavaplugin_osi.so file into the mozilla plugins directory. I did that and when I looked at the "about plugins" page (from Help in Mozilla), it showed a lot of java files. But when I go to any pages that are using java, the page starts to load and then closes. This happened on about 6 different pages (all different web sites). So I think something went wrong. A friend had told me I'm going to have to make a "symlink" (which I don't know how to do). But he's on vacation and won't be back for 2 weeks.
Can anyone help?
Here are the directories where everything is stored. Oh, by the way, when I installed mozilla, java and javaws, I did all of it from the root account. If that was wrong, tell me and I'll fix it.
mozilla is in:
/usr/local/mozilla/
java is in:
/usr/local/java/j2sdk1.4.1_02/
javaws is in:
/usr/local/java/javaws/
Again, as I'm sure you can tell, I'm lost, totally new to linux, mozilla and java. So if you can help, please explain as clearly as possible.
Thanks in advance.

Your friend is correct, instead of copying the .so file you should have made a symbolic link. To do that, first remove "libjavaplugin_oji.so" from "/usr/local/mozilla/plugins"; it's on the way. Then create the symlink with the "ln -s <source> <destination>" command, with your configuration it should be something like:
ln -s /usr/local/java/j2sdk1.4.1_02/jre/plugin/i386/ns610/libjavaplugin_oji.so
/usr/local/mozilla/plugins/
(you need to be root to do that)
To set up web start in mozilla, it might be easiest to go to the demo page and try to launch one of the applications:
http://java.sun.com/products/javawebstart/demos-nojavascript.html
When the "what should mozilla do with this file" dialog pops up, click on the "Advanced" button and make Mozilla handle it with the javaws application. Optionally remove the cross in "Always ask before opening .."

BI Java and BI ABAP -RSPLAN issue

Hi All
We are working with BI system ,using BI 7.0 Java and BI ABAP as separate systems on same host.
Already run the template intaller for BI Java and ABAP integration.
But facing some issue ,when going ot BI ABAP and RSPLAN and clicking the Start Mideller
it is opening a browser as http://host:8000/sap/public/myssocntl?sap-client-XXX
Since this is not correct and it should open BI Java portal instead of ABAP stack page.
Instead this should open a Url like this http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler?
I check on BI ABAP system under SAP Reference IMG -> SAP Customizing Implementation Guide-> SAP NetWeaver _> Business Intelligence-> BI Integrated Planning -> Settings for Starting the Planning Modeler.
There the default Url is BEx Portal Server and the url is
http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler
Can anybody let me know why this is going to ABAP server instead it should go to Java.
Regards
Ajay

How to get return value from java and read by other application?

i want to read return value from java and the other application read it.
for example:
public class test_return {
    test_return(){
    public int check(){
        return 1;
    public static void main(String args[]){
       new test_return().check();
}from that class i make as jar file. How to read the return value (1) by other application?
thx..

If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

Problem with java and flex web service

Hi,
I have a basic web service written in java using jax ws 2.1
ri. I need to call it from Flex using the WebService class
Annotations for the java web method :
@WebMethod
public void Login(
@WebParam(name="server") String serverURL,
@WebParam(name=AUTHENTICATE_HEADER,header=true,mode=WebParam.Mode.INOUTHolder<Authenticate Header>
authHeader)
When I try and call the service from Flex , it can't find the
login method and attempts to call it fail. If I set the web service
to RPC based using @SOAPBinding , the method is found but then
there are issues with the authentication header.
What do I need to do to get flex web services communicating
succesfully with java ?
Are there are any known compatibility issues ? Or guidelines
for going about this ?
Any help would be appreciated

well Shay,
i've used JDev's tools to developer and to deploy the web service: the war and ear files are automatically generates you to the end of the process.
I have included all the files java and the compiled classes, but I do not have files jar.
But don't works: if i create only one java class with all code inside then it works fine!!

Problem with Java and Zip Files

Hello there everyone. I have a problem with trying to zip up directories with empty folders in them. They zip fine with my code, but according to winzip, the number of files in the archive is incorrect. It's supposed to have a total of 288 files in it, but when it's zipped up, it only says 284. I mention specifically the "empty directories" note because the zipping works fine without empty folders.
Below is the code for the zip method:
public static void zip(File[] list, File zipfile, File zipRoot)
     throws IOException {
      if (!zipfile.exists()) {
               zipfile.createNewFile();
          else if (!zipfile.isFile()) {
               throw new IOException("The zip file, " + zipfile.getAbsolutePath()
                         + " is not a file.");
          if (list.length == 0) {
              LOG.error("The list of files to zip up is empty.");
          for (int i = 0; i < list.length; i++) {
               if (!list.exists()) {
                    throw new IOException("The file or directory, " + list[i].getAbsolutePath()
                              + " does not exist.");
          FileOutputStream fos = new FileOutputStream(zipfile);
          ZipOutputStream zos = new ZipOutputStream(fos);
          for (int i = 0; i < list.length; i++) {
               if (LOG.isDebugEnabled())
                    LOG.debug(i + ": " + list[i].getName());
               String entryName = getRelativeName(list[i], zipRoot);
               if (list[i].isDirectory()){
                    if (list[i].listFiles().length == 0){
                         ZipEntry entry = new ZipEntry(entryName + "/");
                         zos.putNextEntry(entry);
               else {
                    ZipEntry ze = new ZipEntry(entryName);
                    zos.putNextEntry(ze);
                    byte[] buffer = new byte[8096];
                    FileInputStream fis = new FileInputStream(list[i]);
                    int read = 0;
                    read = fis.read(buffer);
                    if (LOG.isDebugEnabled())
                    LOG.debug("\tFound " + read + " bytes.");
                    if (read == -1){
                         //empty file, but add it for preservation.
                         //zos.write(buffer,0,0);
                    while (read != -1) {
                         zos.write(buffer, 0, read);
                         read = fis.read(buffer);
                    fis.close();
                    zos.closeEntry();
          zos.close();
The files look like they're there, but I need the system to be able to determine the number correctly.
Here's the interesting thing: It zips the files, and then when I use the size() method for zip files in java, it says 284 files. But when I unzip, it says 288 again. It's like there's files missing when compressed, but when decompressed, they return. Note that the files are actually there. If I open the archive in a third party app such as Winzip AND Winrar AND IZarc, they all show 288 files. Any idea what would make the number of files appear incorrectly in a zip file when zipped by java with the code above? Thanks in advance.
- Chris

I figured out the problem. When zipping files in windows using winzip, it doesn't explicitly count folders as a "file/folder" as a file in itself. It will create the folders for files to go in, but the folder itself will not be 'counted' when you query the info of the file itself. You have more control of the zip file in java, and can count the folder as a file or not.

Compability problem with Java and Python RSA algorithm implementation

I have client server application. Server is writtein in python, client in java. Client receives messages from server encrypted with RSA (http://stuvel.eu/rsa), and I'm unable to decrypt it. It seems that this is RSA algorithm compatibility problem. I'm using algorithm from java.security package, instatinating Cipher object like this: c = Cipher.getInstance("RSA"); . I noticed that this algorithm produces for input blocks of lengtrh <=117 ouput block of length 128. Server I guess uses the most triviall impelentation of RSA ( (1 byte is encrypted to 1 byte) So i want to make my java algorithm compatibile with this one which server uses. How to do that ? Do i have to instatinate Cipher object in different way ? Or use another library ?

azedor wrote:
First you said it was no good because it could only handle <= 117 byte inputs, now you say it is no good because it produces a 128-byte output. You're not making sense.First i said that this two RSA implementations are not compatibile, and first reason i noticed firstly is that Python imlementation for input of length N produces cryptogram of the same length. Not true. In general, the RSA encryption of any number of bytes less than the length of the modulus will produce a result of length near that of the modulus. When N is less than the length of the modulus, it is rare that N bytes of cleartext produces N bytes of ciphertext.
Java implementation for data block of length <=117 produces alwasy 128 bytes of output.Pretty much correct and very much desirable. This is primarily a function of the PKCS1 padding which is used to solve two basic problems. First, as I alluded to in my first response, it is the nature of the algorithm that leading zeros are not preserved and second when the cleartext is very small (a few bytes) the exponentiation does not roll over and it is easy to decrypt the result. Both these problems are addressed by PKCS1 padding.

After what sabre150 said i think of giving up idea of translating Python code to Java and considering to use another assymetric cryptography algorithms on both sides. Can you recommend me sth what should be compatibile with Python ?This seems to be at odds with your statement in reply #3 "Also have acces only to client code so i have to change sth in java." ! This statement is why I said "I suspect ... you have dug a deep hole".
In your position I would use the Python bindings for openssl. Once more, Google is your friend.

Events problem with (Java and ActiveX)

Hi,
I use an ActiveX component with Java and i've got a problem with events.
Java classes were generated with Bridge2Java (IBM).
In order to manage events I added a listener in my application :
javaMyActiveX = new MyActiveX();
javaMyActiveX.add_DMyActiveXEventsListener(new _DMyActiveXEventsAdapter());
I also added a constructor in the _DMyActiveXEventsAdapter class and I fill the body of methods.
The ActiveX generates two types of events :
- The ones are directly generated by methods.
- The others are generated by a thread.
With MS Products (VB, Visual C++, Visual J++), I catch all events.
With java (jdk 1.4), I catch only events generated by methods.
Can anyone help me.

I'm not 100% sure, but the last time I used that bridge, it only worked if you ran your Java app within a Microsoft VM.

I just ran a software update for Java and MacBook Pro SMC, now my Mini Display Port to HDMI TV is not working. The TV is flickering. The Mac Display is fine.

I was just watching / streaming TV off Safari on my actual TV.
I'm using a Mini-Display Port to HDMI cable for the connection to the external display.
Software update popped-up and said there was an update for Java and for SMC.
I ran the update and upon the computer restarting, my external display (my TV) is no longer working. It is now flickering.
It won't work in Mirroring or set up as an extended display.
I've reset SMC / PRAM / Safe Mode / Even restored from a Time Machine backup (From before the updates were done).
What could it be?!

I keep saying this over and over, in the hope that people who do a search will find it. Apple cannot possibly test for or be reponsible for the bazillion combinations of adapter, cables, and TV's out there. The only monitors that are 100% guaranteed to work with the MacBook Pro are the Cinema Displays and Thunderbolt Displays, because, they're made by Apple. They're expensive, but they work perfectly.
My guess is that you bought a cheap MDP to HDMI cable, or have a defective one. From my reading of these boards over the past few months, cheap cables have a high failure rate. And the regular priced ones have only a slightly less of one. Try a new one. Make sure you do not damage the Thunderbolt port.
