Export jdeveloper as jar executable file

hello, I have a simple application developed using jdeveloper which access an oracle database and retrieve data. I would like to export this application as jar executable file. how can I do this using jdeveloper.
Best regards

Add a manifest file that identifies the main class. If you have questions on how to do that using your IDE, I suggest you hit 'F1' or visit a forum that deals with that IDE.

Export Results in Unix Executable Files Instead of .jpg

When I try to export an album to a folder, the exported files are in "unix executable file" format instead of .jpg
How do I fix this?
Mac OS X (10.4.6)

Harley:
Welcome to the Apple Discussions. In the file export window have you selected jpg or "original format" and have the Add extension checkbox checked?
Do the exported files have a extension? If so and it's jpg, then select on and bring up the Info window for it (Command-I). Then under default application select Preview and click on the Apply to all.. button. If you prefer to use a 3rd party editor like Photoshop or PS Elements then select that and click on the Apply to all... button. But the files should have an extension.
Do you Twango?

Including images in jar executable files. Using images in jar files.

Does anybody know what is the reason of my problem??
I created a package called test in my eclipse env. and in that package I placed folder named graph in which there is a file Help.png.
Here is all the code I run in eclipse and it runs properly. When I create a jar file (using eclipse wizard) to execute without eclipse it can not execute and shows nothing (process starts and I have to kill it by myself in OS). Maybe there is some mistake with making jar... I do not know
So let someone try tu run my class or build jar file and try to execute and share his observations (solutions) ??

Problems creating a jar executable file...

Hi there, I am new to these forums, my name is Jay.
I am trying to create an executable .jar file for my program I created in JBuilder 2005, with java files and several other files as well. I am having MAJOR problems with either the main class not being found or failing to load Main-Class manifest attribute.
I tried to make a .txt with two lines, including the first with the MAIN-CLASS: className and stuff and a second line blank, and use the cmf command line to run it and include it in there. I ran it and created it no problem, but then I try to run it, and I get the error of the main class not being found and I have specified the correct directory and class name.
Then I try to make my own manifest file with the correct directory and class name by making a txt file into an .mf file and when I try the cf command line this time, it gives me the error of failing to load Main-Class manifest attribute.
I have even followed the tutorials on the Sun developer website including Manifest making and stuff and everything.
I have worked on this program (java) for months and I am now STUCK. If someone could maybe give me some assistance or suggestions as to what my problem might be, I would greatly appreciate it so much. Or if you want, you can e-mail me, @ [email protected] with suggestions. Thank you all very much.
I have a folder in a directory. It's called SuperPassword, which is the folder where my project files and EVERYTHING is. my .class files are in the classes/superpassword subdirectory of the folder SuperPassword, my java files are in the src/superpassword subdirectory and my manifest file and txt files are in the SuperPassword main directory. Maybe that could give you guys a bit of a hint as to what I am dealing with, I want to explain it as clearly as possible.
Jay

I have a folder in a directory. It's called
SuperPassword, which is the folder where my project
files and EVERYTHING is. my .class files are in the
classes/superpassword subdirectory of the folder
SuperPassword, my java files are in the
src/superpassword subdirectory and my manifest file
and txt files are in the SuperPassword main
directory. Maybe that could give you guys a bit of a
hint as to what I am dealing with, I want to explain
it as clearly as possible.
JaySo I guess you have a directory path SuperPassword\classes\superpassword and the .class files are inside. Are the classes in a superpassword package? If they are, then the Main-Class must be something like "superpassword.MainClass" and when you jar the .class files you need to make sure they are in a superpassword directory inside the jar - like "jar cmf thejar.jar themanifest.txt superpassword\*.class"
You can check the directory structure by displaying the contents of the jar using "jar tf thejar.jar"
Also, remember that java is case sensitive.

How to convert the javasource file(*.class) to execute file(*.exe)?

How to convert the javasource file(*.class) to execute file(*.exe)?
thank you!

Although i have seen a few programs (that are platform specific) that will embed a small jvm into an exe with your class file, it is generally excepted that you cannot create an executable file using java. The JAR executable file is probably the closest your going to get

Jar executable issue after jvm update

I created a small demo application and bundled my classes and media files in a jar executable file. Everything was fine until I updated J2SE from 1.5.0 to 1.6.0_01.
The application now starts, gets its input normally but soon after hangs, and the Swing GUI doesn't show up anymore.
The jar file contains 4 packages (one of them contains the main class) and this simple manifest file:
Main-Class: myapp.myAppLauncher
Classpath: .\myapp.jar
I created the jar as follows:
jar cvfm gdv.jar Manifest.txt myapp mypackage2 mypackage3 mypackage4
I recompiled the source before creating the jar archive, and if I launch the application from the console I see no difference from before. The problem is only for the jar version.

Manually download and install the Java 4 update http://www.apple.com/downloads/macosx/apple/application_updates/javaformacosx105 update4.html, and Safari 4.0.1 http://www.apple.com/safari/download/ Run Software update, install anything that pop up, repair permissions, and restart. That should fix your problem.

Export a "FAT" Jar file

Hi all.
I created a new Java project as a DC in NWDS. This project references jars stored in a library DC with in the same SC.
I am trying to export the java project as an executable jar. The jar will export, but when I try running the Jar, main throws an exception. I have tried updating the build path in NWDS with no luck. I am able to get the jar file to run from the command line if I include the class-path to each external jar. I believe the issue is that the external jars from the library DC are not being included in the executable jar.
Does anyone know how to export a fat jar file which includes the external jars?
Thanks
Ryan

Glad you found an answer, the issue you were having sounds similar to mine (using 3rd-party jars for axis / wsdl4j). According to SDN docs, you create an external library to wrap the jars (sounds like you did). In your public parts for the external library DC, you need to create both the COMPILATION and ASSEMBLY public parts (both representing the jars) and grant access to them from your consuming DC. Sounds like you did that too, I certainly did.
In my case, I had:
SC
    DC -> extjars
      libraries -> contains qname.jar and wsdl4j.jar
      extjars_assm_pp -> ASSEMBLY public part ref's both jars
      extjars_comp_pp -> COMPILATION public part ref's both jars
    DC -> wsdl4jEJB -> references javax stuff in wsdl4j.jar
      dependencies -> extjars:extjars_comp_pp
    DC -> wsdl4jEAR -> packages the extjars and the wsdl4jEJB
      dependencies -> extjars:extjars_assm_pp
    ...Web Dynpro DC that uses the wsdl4jEAR to import the EJB model...
The trick to making the wrapped jars appear in the compilation command line for the DC deployment of the wsdl4jEAR (from Development Infrastructure perspective) was adding the ASSEMBLY public part reference to the wsdl4jEAR dependenciens. Also, the SAP doco was a bit confusing; on the extjars project the doc states to add the jar files to the public part. Be sure to add the jar files as Archives and not as regular Files (otherwise, the jars aren't added to the buildpath during DC deployment build).
Hope this helps someone else if it doesn't actually pertain to the OP's issue, it would have saved me a bit of digging and debugging...

How to get a file in the same dir with the jar-executable

Hi,
I need to read/write a file that exists in the same directory with the jar-executable. How can i do that? I think that when i specify no path for the file, the file has to be in current path. (Is that right?)
Note: I do not know in which directory the jar and the file are.
Thanx in advance

Thanx in advance
When you specify no path for the file, the file has to be in the directory where the virtual machine was started. ( the directory the java command was invoked in .)
If you can't control the directory in which the vm is started, but you know the name of the .jar file you can do the following. This trick takes advantage of the fact that if you are using classes in a jar file, the name of the jar file must be in your classpath.
public static String getPathOfJar( String nameOfJar )
throws Exception
StringTokenizer st = new StringTokenizer(
System.getProperty( "java.class.path" ) ,
System.getProperty( "path.separator" ) );
String jarfile = "";
while ( st.hasMoreTokens() )
String token = st.nextToken();
if ( token.indexOf( nameOfJar ) > -1 )
jarfile = token;
break;
if ( jarfile.equals("") ) throw new Exception( "Jar not found in classpath" );
String path = jarfile.substring( 0 , jarfile.indexOf( nameOfJar ) );
return path;
//To open a file in the same directory as the sun archive tools.jar
File f = new File( getPathofJar( "tools.jar" ) + "someFile.txt" );

How to export the result from executing sql statement to excel file ?

HI all,
Great with Oracle SQL Developer, but I have have a trouble as follwing :
I want to export the result from executing sql statement to excel file . I do easily like that in TOAD ,
anyone can help me to do that ? Thanks so much
Sigmasvn

Hello Sue,
I just tried to export to excel with the esdev extension and got java.lang.NumberFormatException. I found the workaround at Re: Windows Multi-language env, - how do I set English for application lang?
open the file sqldeveloper\jdev\bin\sqldeveloper.conf and add the following two lines:
AddVMOption -Duser.language=en
AddVMOption -Duser.country=USyet now my date formats in excel are 'american-style' instead of german. For example 01-DEC-01 so excel does not recognize it as date and therefore I can not simply change the format.
When export to excel will be native to 1.1 perhaps someone can have a look at this 'feature'

Mac olm outlook files exported as unix executable files

Hi There,
I had to export all my mail in outllook 2011 on my MacBookPro due to size limitations with my company exchange account. When I tried to import the exported file, I noticed it was identified as "unix executable file" & outlook could not import it. I have tried to change the file extension but my Mac continues to handle the file as "unix executable file". I am in complete panic as my entire email archive is contained in this exported file & I am unable to access it. Any help is appreciated. Thanks.

I just tried it and my .olm file is simply a blank document with no application assigned to open it. You need to do a Get Info on the file and select the application to open the file. You might have better luck getting your question answered at the Microsoft Office for Mac Outlook forum - http://answers.microsoft.com/en-us/mac/forum/macoutlook.
Good luck,

How do I put my jar executables into a cab file to create a setup/install?

I want to create a setup program for installing my jar executable. I've seen ones that create cab files with a setup.exe program and would like to do the same. Any suggestions?

Well, JARs generally don't have support files. That's the whole idea. A JAR is designed to be a stand alone application. You don't really need to install it, for that matter. I just thought you might be wanted shortcuts or something.
Actually, there is some way to install Java programs through Java Web Start, if you want to check that out. I don't know anything about it, though.

How do I read a text file in a Jar Executable?

Hello All,
I have a need to package a text file into a Jar Exectable file and then have my java code read that text file in using a BufferedReader. Can anyone out there tell me how to do this? My first question is how do I reference this file by the path name? O, I'm also using Windows.
Thanks for your help.

Well I keep getting errors so I am doing something wrong. The errors I get are:
java.io.FileNotFoundException: jarexample.jar (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:
106)
java.io.FileInputStream.<init>(FileInputStream.java:66)
at sun.tools.jar.Main.run(Main.java:122)
at sun.tools.jar.Main.main(Main.java:903)So I have 3 classes, but after compiling the program I have many .class files: Calculator.class, CalculatorFrame$1.class, CalculatorFrame$2.class, CalculatorFrame.class, CalculatorPanel$CommandAction.class, CalculatorPanel$InsertAction.class, and CalculatorPanel.class. Which files do I want to export into my jar file and do I have to open these class files in Eclipse? Also could you explain the manifest thing first, I have googled for this stuff but get confused because of the class file issue that I previously stated.
Thanks again for helping a noobie out :)

JAR Executable works in netbeans but not under Dos?

Hi all,
I have created a jar executable and it works fine in netbeans(it was not created in netbeans) but I can't get it to run on the command line. If I type java ClassName.MainClass it will run but not using the command java JarFile.jar or java -jar JarFile.jar
Any help would be most appreciated.

When creating the manifest file did you add a carriage return at the end of the manifest? e.g.
Main-Class:Hello.class
(carriage return here on new line)
I think it runs into problems if you dont add a carriage return ( a new blank line after manifest).
Hope this helps

How to export data to multiple csv files?

Hey Scripting Guys,
As stated by the name I'm a novice at scripting. Typically I'm able to resolve most of my scripting challenges by reading through your site or scouring the internet. This challenge I haven't been able to resolve. Please help!!
I'm running a script (posted below) to grab data and export it to a csv file. My challenge is that I want to run the script daily via task manager and have it create a new csv file either daily or weekly. I'm having trouble with the scripting
creating a new csv file. How do I resolve this?
It would be beneficial to append the date to a standard file name, ex. c:\exportedcsv7-11-2014.csv; the next day it would be c:\exportedcsv7-12-2014.csv; and so on.
Thank you in advance to any assistance.
Respectfully,

Thank you for the information and the tip. I took your advice and did some research on Strings, something that I do have trouble grasping. I'm familiar with variables already and feel comfortable using them. I also need to study .Net which
I totally don't understand.
Since I appreciate your advice and guidance I'd like to know if I'm on the correct track. Please look at my breakdown to see if I'm explaining it correctly.
$d=Get-Date
Here a variable is being created using the Get-Date cmdlet, if we execute $d the date will appear
$d.ToString('dd-MM-yyyy')
This converts the date into the format dd-MM-yyyy.
I took the information and tips you provided then came up with this after reading about strings.
export-csv -notype "c:\folder\vmds_$($d.ToString('MM-dd-yyyy')).csv"
The double quotes evaluate the variables. The single quotes do not evaluate anything they just show what's inside of them (a.k.a. literal string). The $() evaluate the expression in ('MM-dd-yyyy') before writing it.
You are correct I definitely need to strengthen the foundation of my basics. Thank you for the direction and advice.
