Standalone executables and dependencies in the Java World

I'm a very seasoned C/C++ developer who's just learning Java. I have this gnawing question that's bugging me. It's rather elementary but it requires someone with experience to answer it.
If I'm delivering a standalone executable (C/C++) to a Windows or Linux customer, it is possible to deliver simply a "*.exe" file (windows) or a Linux Executable file (Linux) which can be installed and run immediately with no dependencies not included in a typical installation. (although, on linux, if there is a gui involved, a typical default Linux install may be missing some dependencies for the gui )
But in the Java world, since the JRE is not necessarily included in a Standard Windows or Linux default installation, my customer would always have to install the JRE on their machine before they can run any code that I produce in Java ...correct? And there is no way to execute a jarfile as a standalone; it always must be executed by the JRE ("java -jar <jarfilename.jar> ) ...right? And if I were to code a new GUI application in Java on the Linux platform, it would have to be run via "java -jar <gui_jarfilename.jar> ...correct?

No, this is exactly what I'm not asking. I mean really standalone ....as in the executable runs by itself without user having to install anything else* (via CD, web or anywhere). So I suppose the answer to my question is that NO, there's no such thing in the Java World and that whenever a java program is installed, it always has the JRE as a dependency and that the installation of a java executable is not complete until the JRE is installed.Not to sound like a noob but what were you expecting. Java runs on the JRE and that is what makes it portable as the JRE can be installed almost anywhere o.O
This is not the inconvenience that you are making it out to be. No user is gonna beef with you if they came to you asking for a java application to be installed and I most certainly have played the client role, having to download the latest JRE to run my bank applets. No so long as you provide the user with all the info they need like a link to JRE download etc you will be fine.. :)

Difference between the standalone executable and an interpreted commond

In the last of this aricle the author mentioned two commonds, I am not exactly sure the meaning ,can anyone give a interpretation?
the article:
[http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html?page=4]

On Windows when you start a command prompt, you are running a program called cmd.exe
When you type "dir" in command prompt cmd.exe itself does something. This is it "interpreting" your command.
If, however, you type "myprogram.exe" then cmd.exe looks for another program in a file called "myprogram.exe". If it doesn't it issues an error message. This is it (still) interpreting your command. If it does find it, however, it runs your program. That program is a "standalone executable".
The distinction becomes relevant when you consider a more complicated command like this:
myprogram.exe > myfile.txt
This instructs cmd.exe to run your program but send any of its output to a file. Your program doesn't know how to do that second part. That's up to the interpreter.
So if you use Java to launch your program it would make no sense to tell it to redirect in this way; you would have to launch cmd.exe and tell that to in turn run your program and do the redirect.

Help with calling windows executable and hiding it using java

Hi,
I have a small utility which calls sqlplus from java , which basically executes a sql file .
Process sqlProcess = runtime.exec(command);
Where command is string and has all the required parameters.
(sqlplus_exe , username_password_sid , sql-file_to_execute_path)
This works fine but it pops up a sql plus window on screen which kindof the user has control .
Like the user can close that sqlplus window before the script gets executed completely.
I want that window to be hidden so that user doesn't have any control on the window and can't interfere with the sql execution.
So thoght about windows api , ShellExecute where you can provide a parameter to hide the window.
Details are in below
[http://support.microsoft.com/kb/224816]
Now the options I have considered to call ShellExecute are JNI / JNA / Smooth
I am using eclipse hellios on winxp
JNI
I Got the code from some website which has all the required files from here [http://www.heimetli.ch/shellexec.html]
But I am not able to run the code .
It says Exception in thread "main" java.lang.UnsatisfiedLinkError: no HSWShellExec in java.library.path
which I am not able to resolve .
Even I had put the dll and .h file in the JAVA Build Path> Library section.
JNA
looks very simple .But I don't know which library to load and call which funtion :(
JSMOOTH
It always gives jsmooth.Native.isAvailable() as false.
And I dont know how to make it true
And also thinks that it works the other way around i.e. Jsmooth loads the JVM .Don't know if it can be called from within jvm
So there I am stuck .
Any suggestions guys.
Any example code would be great.
Thanks in advance.

I got it working with JNI and the sample code from the website
The whole matter was get the path correctly setup in eclipse.
The solution is posted here.

Error when I execute an application with the java command in a DOS prompt

Hi:
I have a trouble. I edit the most simple program in Java: hello.java
In DOS prompt, I compile the program. The result is the file hello.class
c:\> javac hello.java
However, I try to execute this program with the command java
c:\> java hello
and the DOS prompt send me an error like this: Java.exe has a problem and must be closed.
I press the option "Don't send". After this, the DOS prompt returns empty and it doesnt execute the application:
c:\>
By the way, in an IDE editor like Gel, the file hello.java is compiled and executed correctly without problems.
I edited other simple Java files, I compiled them succesfully and I can't run them in a DOS pormpt. The result is the same dialog box: "Java.exe has a problem and must be closed".
The question is: Why don't these programs run in a DOS prompt?
My Operating System is Microsoft Windows XP and the Java compiler version is: 1.6.0_13
Thanks in advanced.

HT1338 I have a Callaway range finder and need a software update and they provided the following directions and have changed the Java runtime versions several times to get their exe to update.Hello Doug, Thank you for contacting Callaway uPro Technical S

Hello Doug,
Thank you for contacting Callaway uPro Technical Support.
Please follow the instructions below to sync your upro mx/mx+ with your computer and update to the latest software - 3.1.005.
1. Ensure the upro sync software is running on your computer (you will see a black icon at the bottom right of your screen by the clock with a Callaway logo in it).
2. Plug your device into your computer; select Sync then PC.
3. The sync software should initialize and launch the uxplore website. If you haven't installed the upro sync software you can download it Here:http://www.callawayuxplore.com/downloads/
4. Download this: http://media.callawaygolf.com/webupdate/callawaygolf/2012/products/accessories/u pro/upro-mx-plus/downloads/3_1_005_launch.jnlp.zip
5. Double click "3_1_005_launch," then click the green START button
NOTE: If you get a "Unable to launch application" error please follow the instructions below.
1a. Navigate to "Control Panel" through the start menu located in the bottom left of your screen.
2a. Find and uninstall any "Java" applications. After uninstalling please go back to the start menu and right click on "Computer" or "My Computer" and select "Properties". In the right half of the pop up windows it'll say the Operating system your computer is running. If it says x64 bit click: http://tinyurl.com/lhkps2rto download the correct java for your computer. If it doesn't have a number please click: http://tinyurl.com/qysyctb to download the correct Java.
3a. Once the correct Java is installed please follow steps 1-5 listed above.
4a. To update your Java back to 7 please click: http://java.com/en/download/index.jsp. Once on the page select "Free Java Download" to run the download (Make sure to uncheck any Mcafee or toolbar installations during the installation).
Once the update has completed the device will restart itself. At that time you can unplug it or select Sync and PC to launch the uxplore site again to continue syncing courses.
NOTE: Do not try to sync courses to the unit while the update is running or both processes will fail.

Java isn't a part of the Mac OS X anymore, so you will need to install a version of Java. However, I don't know what version of java is required for this software. You need to explain to their support that you are using a Mac and what OS you are running. Download the latest java and see if that works.

Specifying Schema Location in XML file and not in the Java code

I have a repository of schema xsd files. When I receive my xml file, I need to validate it against the specified schema. The xml file would declare the schema location, using the following syntax:
<CERD:CERD xsi:schemaLocation = "..\CERD.xsd" xmlns:CERD = "CERD.xsd" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance">
Is it really necessary to define the schema location again in the JAVA code? Why set the schemaLocation in the xml file at all then?
Does anybody have any examples where the schema location is not set in the JAVA code? I am using Java 1.6, and at this point in time I only need to validate. Any help would be appreciated.

Thank you very much for your quick reply. I have made some progress but I am still stumped.
In my code I am doing this:
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema();
Validator validator = schema.newValidator();
validator.validate(XML_SOURCE);
I find this works if my schema does not have a target namespace. I have downloaded the following simple example from the internet that uses a target namespace and it fails:
library1.xsd:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://example.org/prod"
xmlns:prod="http://example.org/prod">
<xsd:element name="product" type="prod:ProductType"/>
<xsd:complexType name="ProductType">
<xsd:sequence>
<xsd:element name="number" type="xsd:integer"/>
<xsd:element name="size" type="prod:SizeType"/>
</xsd:sequence>
<xsd:attribute name="effDate" type="xsd:date"/>
</xsd:complexType>
<xsd:simpleType name="SizeType">
<xsd:restriction base="xsd:integer">
<xsd:minInclusive value="2"/>
<xsd:maxInclusive value="18"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:schema>
<prod:product xmlns:prod="http://example.org/prod"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="library1.xsd"
effDate="2001-04-02">
<number>557</number>
<size>10</size>
</prod:product>
I get the following SAXParseException when I validate:
[line 4, col 36|
cvc-elt.1: Cannot find the declaration of element 'prod:product'.
Am I doing something wrong with the namespace declaration?

Executable and dependencies

Labview 2012/Windows 7.
On my developemnt machine I created a project w all my vis to run a test. That works fine. I then created an exe and that works fine. Then I created an installer for the target machine and the code doesn't work. I get that its missing files and those files just happen to be listed under "dependencies" of the project on the devmnt machine. To name a few..."vi.lib", "instr.lib", nidmm_32.dll", niswitch_32.dll". In the build I included DAQmx and visa as well as the RT engine. I selected my "Main Menu" as the "startup vi. Main menu calls all of the "other vis" which are in folders in the project under main menu. The discussion grps have some confusing info. Should I put the "other vis" that my main menu calls in the "Always Include" box or when I select main menu as my startup vi Labview is smart enough to include those called vis??
What am I missing that I get an error when I port my code to the target machine ? ..."vi.lib", "instr.lib", nidmm_32.dll", niswitch_32.dll".

Hi Clint,
as you miss "nidmm.dll" I guess you need to install the NI-DMM driver as well with your exectable…

What's going on in the java world?

Hi guys,
I haven't used Java since 2002. What's going on here. Would u tell me? Will be a great help.
Thanx.

Hi guys,
I haven't used Java since 2002. What's going on here.
Would u tell me? Will be a great help. A lot actually. Java has come of age. It's fast, stable and the Swing emulations really passable.
The abandoned Java3D has made a come back as open source (kind of).
A new major Java version called Tiger has been released with lots of language changes that elevates the Java abstraction level a notch. This includes generics, autoboxing and highlevel concurrency.
Eclipse is better than ever.

You are missing a closing parens. You have :
if(type = "Return")
FlightServiceClient client = new FlightServiceClient(ServerFlightServiceURL);
ArrayList list = client.getFlight(arr, des, FDat, TDat, type, clas, adult, child);
Iterator it = list.iterator();
while (it.hasNext()){Which opens two parens but you only have one closing parens

Executing jar command from the java application

Hi All,
In my application i want to create a jar file with the existing class @ Runtime and want to download . But i tried to execute the jar command via Process.getRuntime, it throws IOException. Please guide me or give the solution

PavithraKarthikeyan wrote:
Please guide me or give the solutionQuestion your need for this. Why do you think you need to create the jar file.
P.S. The jar command is only available if the user has the JDK installed so if he has only the JRE installed then you have a problem using Runtime.exec(). There are classes (java.util.jar.JarFile et al) that will allow you to jar files using Java code.

How to execute unix command from the Java program running on Windows

Hello,
I need to
1. Execute a unix shell script from a Java program running on the Windows.
2. I also need to capture the output of this shell script in my program.
Please suggest me how to achieve this.
Thanks in Advance.

Hi...
Something is missing here
If you want to execute a shell script in windows that not posible unless you find or develop a unix shell script parser for windows.
But if you are trying the execute a unix shell script on a remote unix computer from your java program running on a windows platform you can do that by logging on to the UNIX terminal which is running on port 23 I think.
You can test this using telnet tool on windows
just type on command prompt
telnet <ip of the unix pc> <port number this case 23>
you should get the unix terminal. If that works you can do the same through java or you can directly conect to port 23 of that pc using sockets that way your program will be platform independant

XI System backup and restore for the JAVA Stack

Hello experts
I am few queries regarding backup of XI System.
1- What is the procedure to backup the XI System on AIX OS?
2- Should I backup the J2EE Engine also with Jload and Java migration toolkit, when I backup the XI System?
3- If XI system crashes, what is the procedure to restore XI system from backup?
4- Do I have to restore the J2EE Engine also from backup with XI with the help of Jload and Java migration toolkit. If so, what is the procedure on AIX OS?
5- If I take a backup of XI system, after 3 days the server crashes. When I restore the backup, how should I recover the lost messages of 3 days?
Kindly help me out with these issues. If anybody has any documents, kindly email me at [email protected] Points will be rewarded for any kind of help. Thanks a ton in advance.

Hi Bipin,
This blog contains very little info. It says zip the XI files and extract the compressed zip files. Also it talks about backup of registry.
I am on AIX OS. How can I backup the registry in AIX? Also how should I zip all the files and extract those compressed files during restore. Is there any SAP utility to do that. Kindly let me know.

Hi Harshit,
You mention "Unable to access the http://localhost:50100/irj and http://localhost:50100/nwa only http://localhost:50100 is working."
But did you tried http://<HOST Name- FULL FQDN>:50100 ?
Check whether this is working alright if not then it is related to either firewall or some network config issue (e.g. DNS or IP resolution issue).

Wating four your replay.
Yours Friend
Bhavin Shah.....

pr = rt.exec("cmd.exe /c start " + yourProgramName)The exec() method executes the command you specify in the argument and returns a process. In this example, it's telling Windows to run "yourProgramName".

Solve the problem that stumped the Java world

A little background: For a couple of weeks I have been posting queries for help
with several problems in my table-based application. Usually I have gotten calls
for more code. I have stripped the app down to the ONE problem that remains. The
code included below is 772 lines long (down from over 2500) for five files.
I post this query for anyone who is still interested in the problem.
I am hoping that the solution is short work for an experienced Java coder, though I can't figure it out.
Table1 145
Table2 152
T1RowDragger 211
T2RowDragger 243
"main" class 21
 total 772
The goal is to copy a row from one JTable (table1) to another (secondTable). To do
that I need to connect "t1DataModel," the DefaultTableModel of table1 to
"T2RowDragger," the Drag and Drop class of secondTable.
This is the method which should handle the copy It is located in "T2RowDragger": public void interTableCopy( int rowNumber, int position ) {
 DefaultTableModel t1DataModel = (DefaultTableModel)table1.getModel(); -------- the problem
 Object t1SourceRowData = t1DataModel.getDataVector().elementAt(rowNumber);
 DefaultTableModel t2DataModel = (DefaultTableModel)secondTable.getModel();
 Object t2SourceRowData = t2DataModel.getDataVector().elementAt(rowNumber);
 t2DataModel.getDataVector().setElementAt(t1SourceRowData, position);
 t2DataModel.fireTableRowsUpdated(position, position);
 secondTable.repaint();
 }However, it returns a NullPointerException at the first line of the method.
My diagnostic printout to the console reads:
 "t1DataModel = null
 t2DataModel = SecondTable$SecondTableModel@202ac00
 t2SourceRowData = [, , , , , , , ]
 T2RowDragger: Drag Dropped at : Row 12"
When this version is run:
 public void interTableCopy( int rowNumber, int position ) {
 // DefaultTableModel t1DataModel = (DefaultTableModel)table1.getModel();
 System.out.println( "t1DataModel = " + t1DataModel );
 // Object t1SourceRowData = t1DataModel.getDataVector().elementAt(rowNumber);
 // System.out.println( "t1SourceRowData = " + t1SourceRowData );
 DefaultTableModel t2DataModel = (DefaultTableModel)secondTable.getModel();
 System.out.println( "t2DataModel = " + t2DataModel );
 Object t2SourceRowData = t2DataModel.getDataVector().elementAt(rowNumber);
 System.out.println( "t2SourceRowData = " + t2SourceRowData );
 // t2DataModel.getDataVector().setElementAt(t1SourceRowData, position);
 t2DataModel.fireTableRowsUpdated(position, position);
 secondTable.repaint();
 }Please note that (1) the drag and drop code is written in the Macintosh API. (2) the code is not exactly pretty.
As always many thanks for any assistance.

Hi,
Instantiated a variable is like...
JTable table1 = new JTable();
if you do
JTable table1
System.out.println(table1);
JTable table1 = new JTable();
it will print "null", and if you do,
table1.someTableMethod() you will get an error!!!!
Do not take that personnal(;0)))) but I know that you do not have a lot of experiece just by looking at the way you are selecting the name for your variables... like Table1, table1 and secondTable...But believe me, by working here on the forum you will be a pro soon.
Take care,
JRG
