Java and ActiveX

Hey,
I'm trying to use the JACOB software to incorporate ActiveX control within Java but I am having problems installing\getting it working.
I was wondering does anybody know of any other tools I can use or has anybody actually got the JACOB tools working on there PC?
I've posted on one JACOB forum but have not gotten a solution to my problem. Below I have posted a detailed description of the problems I'm having with JACOB. If anybody can help, any input will be greatly appreciated.
I've been struggling this week trying to get the JACOB
software working on my PC. In trying to get it
working I am using the Applet Example(AppTest.java)
located at:
jacob_1.10-pre4_src\jacob_1.10-pre4
\samples\com\jacob\samples\applet
The specific problems I am having are as follows.
1. The code compiles fine the javac command and
jacob.jar in the classpath (not really a problem , I
know...)
2. I've commented out the first line of "AppTest.java"
because I have moved the sample onto my hard drive out
of the zip file. The line I'm refering to is;
package com.jacob.samples.applet;
Is it OK to do this?
3. After taking this action the Applet will load ever
however it will not take any action if I press
the "calculate" button (continues to show "?"). This
lead me to think that the function "actionPerformed"
does not execute once I press the button.
4. Also, the Applet fails if I try defining an ActiveX
object inside the function "init". The error
is "java.lang.ExceptionInInitializerError"
Is there anything wrong with defining an ActiveX
object inside the "init" function? Actually this is
another item that makes me think that function
"actionPerformed" does not take place. Because
otherwise I should have seen this error earlier when I
clicked the button, Right?
This also leads me to think its an install problem
because it "craps out" once I try using the JACOB
tools.
5. There is a line of code that refers to Eclipse. I
do not have Eclipse installed on my machine. Will
that cause the Jacob tools not to work?
6. For the install I have placed jacob.jar in the
folder <JRE_Root>\lib\ext and Jacob.dll in
<JDK_Root\bin> folder. I am using Java JDK and JRE
versions 1.5 on a Windows PC. Am I missing a step?
Thanks,
Bill

Before we go any futher using ActiveX from an applet is tricky and is best avoided.
Now onto your problem. From your description I would say there is a problem with your Swing code and/or the security restrictions of your applet. Yes JACOB works but I highly, highly recommend you start off with a vanilla console test program and work your way up from there.
Once you get it working in a console then add a GUI. Once that works turn it into an applet. It's hard to diagnose exactly what is going wrong at present.
Again though it will and does work you just have some problem but what I don't know.

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.

How can I open a program using Java and then perform certain tasks with it?

For example, and this is just an example, I want to write a Java program that opens MS Paint and then manipulates that program. This can be useful to automate certain tasks.
My question is whether this can be done writing Java code and if so how? If not possible, would I need to use a scripting language instead?

write a Java program that opens MS Paint and then
manipulates that program. This can be useful to
automate certain tasks."manipulates" is a too wide term. Let me narrow down:
1. If you want to open (run) the program and then shut (kill) it down it is possible and fairly trivial to do in java. Look up Runtime and Process classes in java.lang package
2. If you want to open the program and edit some image/document in the opened program. It is very difficult in java. May be possible... using some Java/COM bridge, assuming your native program is COM/Active-x compliant. Note: these things go beyond the boundary of JVM and needs to interact with host OS and involves shared memory, ipc and all "low level" stuffs.
If you want to be able to play around with these COM/Activex apps- choose .NET instead :-)
3) You can open the program from java and pass it some command line arg as in (1) above and then the program will load that document/image at startup automatically. You may then edit the doc/image thru that program itself. However, Java is not doing anything for you here, other than just starting off your native mspaint.exe ot notepad.exe.

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.
Gilbert

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.

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.

guess what it says java file. So yes i'm sure. Sarcasm. Not the best way to encourage a total stranger to help you. Then there's
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.

LabVIEW Run Time Engine and ActiveX Automation Server

Hi,
I have a question related to LabVIEW Run Time Engine and ActiveX Automation Server:
We have a tool developed in LabVIEW and TestStand. End user interface is a LabVIEW GUI (it's an executable) which executes TestStand sequences. Some TestStand sequences call lower level LabVIEW VIs.
Everything works fine with LabVIEW installed, but I was wondering if I could run this tool on deployment machine with only LabVIEW run time engine installed. We are using LabVIEW 6.1 and with only the run time engine installed, I get the error message: "Unable to launch the 'LabVIEW.Application' ActiveX automation server ".
BTW, we are planning to upgrade the versions soon.
Is it possible to make things work only with the run time engine?
Thank you.

Thanks for the response, Brian.
I did upgrade to LabVIEW 8.0 and TestStand 3.5. Everything works fine on the development computer where LabVIEW and TestStand is installed. On the target computer in the lab, I installed LV RTE 8.0 and TestStand 3.5, and now when a VI is called in a sequence file, I get the following:
RunState.PreviousStep.Result.Error.Code -18002
RunState.PreviousStep.Result.Error.Msg "LabVIEW: The VI is not executable"
So, the executable opens and works fine (which means that the LV RTE is installed properly), but when a sequence calls a low level VI, it does not make it through.
comments/suggestions are appreciated. Thanks.

[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.
(1) Just for the record, here are a few posts that refer to modelling the DB in UML:
[A post on this forum highlighting that UML 1.4 standardizes a notation for RDB modelling|http://forums.sun.com/thread.jspa?messageID=1383724#1383724]
[A DB modelling tutorial|http://www.tomjewett.com/dbdesign/dbdesign.php] (not sure whether it leverages the standard mentioned above :o)
P.S.: "Java and all else" as in, damn, I'd love to use the familiar JDC forums and people to discuss not only Java-related issues, but also [all other things that surround Java|http://forums.sun.com/thread.jspa?threadID=5422264&tstart=0] (other technologies, processes, people) and enable to make workable systems out of Java code.

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.
