Java and C ??

Hi.
Can anybody tell me if its possible for a java file to communicate with an executable c file ?
for example, if the executing c file is waiting for any key to be pressed e.g.( "getch( ) ;" ) to continue, can a java program supply this keypress ??
Can anyone suggest a fix ?
thanks
pmac.

I believe that, since you have an executable (.EXE) file, that JNI is not what you want. JNI is for communication between Java programs and DLL's, and is typically used to integrate code that cannot be written in Java (platform specifics) or for better performance.
Look at java.lang.Runtime.exec() - it can be used to invoke a native process. It returns a java.lang.Process, which has methods to interact with the Input and OutputStreams of that process.

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 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?

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.

I'm new to Java and can't get javac command working

Ok first of all hello ( i'm new to the forum ), second i'm reading a book about Java and im trying to compile a sample code from the book, but javac command gained life and it's against me. So the book i'm reading is Sams Teach Yourself Java in 21 Days (YAY), and the code i want to compile is an application that works with another bit of code that mimics what a robot could do inside a volcano. So the Volcano program code is the following ( i'll post the robot code at the end of the post):
1: class VolcanoApp {
2: public static void main(String[] arguments) {
3: VolcanoRobot dante = new VolcanoRobot();
4: dante.status = ?exploring?;
5: dante.speed = 2;
6: dante.temperature = 510;
7:
8: dante.showAttributes();
9: System.out.println(?Increasing speed to 3.?);
10: dante.speed = 3;
11: dante.showAttributes();
12: System.out.println(?Changing temperature to 670.?);
13: dante.temperature = 670;
14: dante.showAttributes();
15: System.out.println(?Checking the temperature.?);
16: dante.checkTemperature();
17: dante.showAttributes();
18: }
19: }
Ignore the numbers they are used for explaining stuff in the book, and i din't copy the indentation.
So what i do is that i creat a file with notepad ( no fancy stuff only plain old notepad ) and i copy this code, remove the numbers and make the indents.
After that i save as .txt file with the apropriate name ( i know it's case sensitive ). After that i open command prompt and write:
javac VolcanoApp.java
And it tells me that "javac is not recognized as an internal or external command operable program or batch file".
I managed to solve that by going to the control panel and by adding to the system variables for my user in the path variable this :
;C:\JAVAJDK\bin
( C:\JAVAJDK is where JDK is installed)
And then i modified the system variables like this:
In the CLASSPATH i entered this .;%JAVA_HOME%\lib\tools.jar
In JAVA_HOME i entered this C:\JAVAJDK
Setting the variables like this made the javac error go away but now when i write in command line
javac VolcanoApp.java
It gives me this error
javac: file not found : VolcanoApp.java
Usage: javac options source files
use -help for a list of possible options
And then i read that i can drop my java file directly in the javac file. So i did.
When i drop my VolcanoApp.java in the javac file it open a command line window and writes a bunch of stuff in like a milisecond and shuts down. And no file is created.
I wanted to know what was writen in that window so i did it again and took a print screen and pasted it on paint ( it writed so much text that i only got a little bit but enough to see what hapend)
I read it and in the print screen it said it had 15 errors ( so far ) and then it point the errors with little arrows and there were characters that weren't present in the original code.
What hapend the compiler added wierd letters?
SO, my real question is, how the heck do i get javac working and compiling stuff properly?
Plz help i'm getting mad at this! ; (
And the code for the "robot":
1: class VolcanoRobot {
2: String status;
3: int speed;
4: float temperature;
5:
6: void checkTemperature() {
7: if (temperature > 660) {
8: status = ?returning home?;
9: speed = 5;
10: }
11: }
12:
13: void showAttributes() {
14: System.out.println(?Status: ? + status);
15: System.out.println(?Speed: ? + speed);
16: System.out.println(?Temperature: ? + temperature);
17: }
18: }
Again no indents and ignore the numbers. In the book it only said to compile the VolcanoApp.java , and not the VolcanoRobot.java
Edit:
I'm using Windows Vista Home Premium 32 bit.

Sorry if i wasn't more clear but was that response needed?No it wasn't needed, but I'm not the one asking for help so I have the luxury of not worrying too much about it. It's extremely frustrating trying to drag relevant information out of someone, and makes one less inclined to bother.
Anyways, there's still nothing in this thread that actually explicitly says "there is a file called VolcanoApp.java in the directory where I'm running javac from" and I really can't be bothered banging my head against the wall any longer. You've made a silly mistake, or a false assumption. We all do it from time to time. My advice is, take a break, go for a walk and re-visit this in a while. You'll probably spot the mistake right away.

[Java and all else] How do you document DB design?

Hello,
Although most of the technical choices are explicit in SQL (UniqueKey & ForeignKey constraints, indexes,...), the semantics of the data columns and their constraints seem better served as plain human-readable comments ("ID column: identifies the plane copy; 6 figures are enough as we don't expect to sell more than 1 million planes in a foreseeable future...").
In my current system, (EJB-based, but the DB schema is not created by the JPA-compliant ORM, but via SQL scripts), I see the following ways to write and maintain this documentation:
- SQL comments in the schema creation and patch scripts
- Javadoc comments in the Java source of the Entity classes.
- UML notes in UML diagrams(1)
- external "Architecture and design" document.
All 4 of them are used, sometimes inconsistently, for various parts of the design choices; I mean, the docs do not contradict themselves (not yet, but it's a mere question of time), but some tables are commented in SQL scripts, others are in design docs, and the details for some columns are in entity javadocs. Although each developer may find it handier to "write" the doc via his preferred medium, it becomes increasingly difficult to "maintain" theoverall documentation.
Our current situation is that most of the project team members are Java developers, so it would probably be better accepted and served if we standardized that we document DB tables and columns in Java source, but I am worried that:
- someone else pouring over our DB (ex: DBA helping us to optimize things, or other team developping a data-mining tool to leverage the historical data in DB) may not be as comfortable with Java
- this may not cover all design choices of the DB schema:
- - - - first, although that is the case currently, in the future there might not be a 100% 1-1 mapping between e.g. each entity class and a DB table. Maybe some columns will not need to be mapped anymore,...
- - - - second, I fear some DB constructs are not amenable to Java counterparts; no accurate idea there, I'm not an SQL nor JPA expert, but I presume Indexes, table partitioning, tablespaces, for example (yes, the DBMS is Oracle :o) are not taken into account in JPA mapping.
And if we document those choices at the SQL level (my preferred idea so far), this will gradually make the javadocs in the entities obsolete, or removed altogether, and that will make future maintenance of the Java source risky.
How do you document your DB design in general?
Do you have specific advices for my case?
Thanks in advance,
J.

Thank you again.
A couple more questions:
2. Table, and proc dictionary maintained as one or more text files. Those files and schema are all in source control.Do you mean, a proprietary text format (a la tabledesign.txt), or +.sql+ source files? Again, you seem to suggest the scehma info is present in two locations.I didn't say two locations unless you meant files. Then yes.Yes I meant two files. I trust the team to get the doc file lagging a few revisions behind the SQL file, and to correct that I would have to include one more step in the review process (e.g. "review CM actions to check that the doc file is updated consistently with the SQL source").
The tool I wrote would throw errors if the comment file didn't match the schema. And if comments were not provided. That of course doesn't stop someone from documenting a table with "a table".
You can of course keep the addtional info as special comments in the SQL, but when I did this, and even in retrospect, it seems better and perhaps easier to keep them seperate. I have done special comments in SQL before and it seems a bit of a kluge but you do have the single source. But in that case I was the only one maintaining it too.What do you mean by "special"?For code generation I have a schema file with the following (pseudo sql.)
    create mytable
       mytable_id int,
       column_foo varchar(10);
       column_fum varchar(20)
        -- Query: for_a_query (column_foo, column_fum)
    )The generator consumes the schema and generates the standard CRUD which would include a query based on the primary key.
The above comment is used to provide an additional query where the proc is named 'for_a_query' (munged with table name) and takes two parameters (column_foo, column_fum) whose type/name matches those of the table.
If we don't try to generate a browseable HTML out of the schema (although the idea is appealing, I don't have the resource to make such a tool), do you see anything kludgy in maintaining SQL comments interpersed within DDL code?
Of course that is doable.

RE: Java and Forte

We have no problem using JDK 1.1.5. However, we are using Orbixweb. If
you are accessing the applet and the IOR file from the same host (exact

client application, which includes all the client stub files
(including stub files which are generated from Forte supplier plans
such as those in the Framework folder). However, I still receive the
AppletSecurityException.
How can I go about making this operation successful?
**AppletSecurityExceptions can be caused by many problems--trying toaccess
machines other than the class download machine, or trying to accessserver
side classes outside the defined directory structure in the webserver. I'd
look closely at the classes that are being brought into memory (forexample,
Visibroker's ORB shows you each file as it is loaded) and make sureyour web
server is defined correctly. If you follow the Forte technotesclosely, it
usually solves this problem.
2. Has anyone tried implementing a 'fat' client, one that combines a
Forte web application, JavaScript, and a Java applet client toperform
operations such as validation and a tiny bit of data processing allon
the client side, relieveing the application server from such
operations? If yes, how do I implement the solution, and are thereany
tech notes from Forte that specifically tell me how to do this?
**We have created a Java framework that follows many of the designpatterns
and naming conventions as our Forte framework. The Java classes canbe
extended to marshal and unmarshal scalar data structs passed acrossthe ORB
boundary to instantiate 'thick' functional objects on the client, andas much
processing and as many business rules as wanted can be developed inthe
client
Java objects.

If you look at the exception information in the iiop manual it
discusses exteneded propties DefaultThrowsClause, ThrowsClause and
IsThrowable.
If you mark your exception class with IsThrowable it will show up in the
IDL as an exception. If you use either DefaultThrowsClause(project) or
ThrowsClause(method) you will get the appropriate raises in the idl.
This will cause the idl2java to produce code which will allow you to catch
the exception.

Hi all,
I am currently working to an architecture to establish a communication
between a Forte' server and a Java client, using Visigenic's Visibroker and
IDL mode.
I have problems when I try to raise a Forte' exception from a method
invoked by the Java client; I would like the exception class
(ProductException) not to inherit from the class GenericException, because
the IDL I want to generate must have this structure:
exception ProductException {
string message;
Using this solution, the client application gets blocked waiting forever.
I am currently working with:
- Forte' 3.0.G.2 plus WebEnterprise 1.0.B
- JDK 1.1.5
- Visibroker 3.1
My question is: is it possible to raise an exception from the Forte' side
that is
compliant to the IDL mentioned above?
Of course it should be caught from the Java side.
Thank you in advance

Java and Internet Explorer automation

Hi,
I would like to create a routine in java that would simulate a user browing the web.
Ex: A user vistiting a certain page, clicking on a few links etc...
Is their a java library that can server as a bridge beetween java and internet explorer in order to automate this process.
Thank you.

You want to see it all happening on the screen? If so, you could maybe look into IECanvas or some other Java/COM bridge that would let you embed IE in the Java app. I'm not sure what kind of API is available such that would allow for that.
Another idea is java.awt.Robot which would let you move the mouse and enter text and click on things on any application, but the problem here is that you'd need to know exact coordinates to click on. You could use it to grab screen shots if you can deal with the image manipulation to figure out what is where.

With Firefox 5.0.1 and Firefox 6 beta there are display problems apparently due to Java and some Javascript compatibility problems -- there were links to solutions, but they are no longer active. What to do?

The box and button lines are not displayed or are mis-sized, if they appear at all; problem varies with the website and page style.
The threads I found in discussions mentioned a couple pages that are no longer active/cannot be opened -- so these solutions don't work.
When starting version 5x and 6beta I get information certain add-ons are STILL incompatible with these versions?
Are there any work-arounds or patches?

I am having this problem too. Just like WinOnBatch the problem started for me around firefox 5.0.1.
I have not been able to get rid of this problem. I have tried creating a new profile, restarting firefox in safe mode. disabling extensions 1 by 1. When I built this computer I did a clean install of firefox 5.0.1, and 2 weeks later with no extensions the problems came back. At that point I had the Java and flash plugins only.
When firefox 6 was released I did another fresh install (uninstalled firefox, went through my hard disc and deleted any reference to firefox and mozilla. Did the same in the registry, then run a registry cleaner and restarted the computer) before I installed firefox 6 and the problem was happening in less than a week. The I said to hell with it and re-created my entire profile from scratch and installed all my old extensions (updated them off course). 2 weeks ago it got really sever and I couldn't see any buttons on the chome interface and all web pages I visited were displaying really messed up. The only way i can describe it is kinda like greentech70 screenshots but on every inch of the application window. Like a really bad screen tearing effect.
The only thing that seem to help is when I downgraded to firefox 3.6.18. That fixed it but like greentech70 I have security and privacy concerns, so upgraded to firefox 6 again as the issue went away for 1 day, then came back but not as severe. since then I have been downgrading to firefox 3.6.18 re-installing java and flash, then upgrading back to firefox 6. It keeps the problem minimised but im still plagued by it. I also wonder if its a problem with firefox's 6 graphical engine.

Java and C ??
