Wrong charset in jar file
I'm using NetBeans 6.7.1, Firebird 2.1 with UTF8 charset. "jdbc:firebirdsql:localhost:erpdebug?sql_role_name=TENDERING;lc_ctype=utf8"
All works fine until program inside NetBeans. When jar file starts outside IDE - all non-English characters becomes corrupt. Only database data, not entire program.
Much clearer, thank you. However:
I cannot set any locale to IDE at allIn sincerely doubt that that is true - I'm no NetBeans expert, but it's a Java app that (in turn) runs Java apps. I'd expect you to be able to set the locale at both levels and I'll be astonished if it's not possible. I'm not saying that's the bug, but it's the first thing I'd want to check.
Any NB experts in the house?

Hi All,
I have a moronic question. I have a simple jar file called xmlpowertoolkit.jar and I can't get any of the classes in it imported into my simple console app.
I unpacked the jar file to look at the namespace hierarchy since I have no documentation with this jar file. It came out like this:
xmlpowertoolkit\com\sabre\xmlpowertoolkit\
... then a bunch of classes in this directory. Specifically, there is a class called XMLPowerToolKit_Services that I need to use. Here is a typical constructor call for this class:
XMLPowerToolKit_Services myvar = new XMLPowerToolKit_Services ();
Can someone tell me what I'm doing wrong with this jar file? How do I import this namespace so that I can use the class?
Do I not say:
import com.sabre.*;
Thanks for your help.
Steven TateTry
import xmlpowertoolkit.com.sabre.xmlpowertoolkit.*;
OR
import com.sabre.xmlpowertoolkit.*;
I think com.sabre.* will just get you the classes at that "level" ... it doesn't grab the classes in subfolders.
i hope that works. -
Dear all,
I am new to Java, but I try to implement a small application which talks to our SAP. I am working with eclipse 3.3 and I've installed JCO 2.1.8. I modified Example1 a little bit and everything works fine when I start my program within eclipse with run as->java application. I added the sapjco.jar file to the build path of my project. I also added C:\Programme\sapjco-ntintel-2.1.8 to my windows path variable and copied *.dll to system32. When I export my project as a .jar file and try to start it with
java -cp C:\Programme\sapjco-ntintel-2.1.8\sapjco.jar;. -jar Jco.jar
I get the error message
java.lang.NoClassDefFoundError: com/sap/mw/jco/IMetaData
The contents of my .classpath file is:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="lib" path="C:/Programme/sapjco-ntintel-2.1.8/sapjco.jar"/>
<classpathentry kind="output" path="bin"/>
</classpath>
But I can start the java program with
java -cp C:\Programme\sapjco-ntintel-2.1.8\sapjco.jar;. Jco
when I am in the directory with the .class file.
Whats wrong with my .jar file?
Thanks in advance,
Rolf

Rolf WinterHi,
thanks for your answers.
C:\Programme\sapjco-ntintel-2.1.8 containing sapjco.jar is already added to the path environment variable.
summary:
-I installed JCO in folder C:\Programme\sapjco-ntintel-2.1.8
-I copied *.dll to Windows\system32
-I added C:\Programme\sapjco-ntintel-2.1.8 to the path environment variable
-sapjco.jar is in the building path
-<i>I can start the "normal Java .class file"</i> with java -cp C:\Programme\sapjco-ntintel-2.1.8\sapjco.jar;. Jco
-I've created a jar file with the export dialog. I just followed the steps and selected the starting class "Jco".
-In the directory containing the jar file I tried to start it with the following commands
java -cp C:\Programme\sapjco-ntintel-2.1.8\sapjco.jar;. -jar Jco.jar
java -jar Jco.jar
but I always get the message
Exception in thread "main" java.lang.NoClassDefFoundError: com/sap/mw/jco/IMetaData
Any further ideas?

JWS requests jar files at the wrong place
Hi all,
I created JWS project with netbeans, and by deafult, NB places all required jar files in the "lib" folder. NB also created jnlp file with correct paths to required files. It looks like this
<update check="always" policy="always"/>
<resources>
<jar download="eager" href="main.jar" main="true"/>
<jar download="eager" href="lib/required.jar" main="false"/>
</resources> Now, when app is started, required.jar is correctly located at lib folder and application works, but from that moment on, JWS makes hundreds of request for "${codebase}/required.jar" (obviously wrong place) and gets 404 responses. It keeps making these requests as long as app is running and this slows down application significantly.
My temp workaround was to move required.jar to codebase root and problem is gone, but i still find it weird. I guess this may explain some complaints about slow JWS.
Is this a bug? Am I doing something wrong? Is there anything I can check?

Invalid MAGIC number in jar file
HI Gentlemen,
I just compiled a java file into a class file and then set up a jar file with that one single class. Manifest indicates that the Java version is 1.7.0 as is any other development tool. Now I am inspecting the file with my hex editor and it does not contain CAFEBABE as a magic number. However, a legacy jar file in an Applet sample code has it and works correctly. It was as well with my JDK 1.7.0 compiled. What can be wrong with my method? JDeveloper does not accept the jar when I want to deploy and call the applet.
Please help if you can.
Many thanks in advance, kindly regards
Miklos HERBOLYHI gimbal2,
Thank you for your reply. Just to start with, I included here some stuff.

Using a JAR file as a project file
My application allows the user to create projects. Previously, a project file was simply an XML file. Now, a project file needs to also contain many images.
I thought it would be a good idea to simply use a JAR file as my project file.
Since I've really never really worked with JAR files and the java.util.Jar package directly, I have a few questions.
1) Would it be better just to simply store the images as binary in the XML file? I just spent a good amount of time making the XML file very readable so I thought it would be better to keep the images separate while still having a single "project" file.
2) Is there anything inherently wrong with the way I'm working with the JAR file in the code below?
Simple XML file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE project [
<!ELEMENT project (img+)>
<!ELEMENT img EMPTY>
<!ATTLIST img src CDATA #REQUIRED>
]>
<project>
<img src="blah.jpg"/>
</project>
import java.io.*;
import java.util.jar.JarFile;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
public class LoaderTest {
private String imageName;
public LoaderTest() {
InputStream i = null;
JarFile jf = null;
try {
jf = new JarFile("project.jar");
i = jf.getInputStream(jf.getJarEntry("project.xml"));
// Here's my simple XML parser to load the project and images
SAXParser parser = SAXParserFactory.newInstance().newSAXParser();
parser.parse(new InputSource(i), new DefaultHandler() {
@Override
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
// Right now we only care about images
if (qName.equalsIgnoreCase("img")) {
imageName = attributes.getValue("src");
// Load the image from the inputstream
java.awt.image.BufferedImage img = javax.imageio.ImageIO.read(jf.getInputStream(jf.getJarEntry(imageName)));
// Display the image in a JFrame
javax.swing.JFrame f = new javax.swing.JFrame();
f.setLayout(new java.awt.BorderLayout());
f.setSize(800, 600);
f.getContentPane().add(new javax.swing.JLabel(new javax.swing.ImageIcon(img)), java.awt.BorderLayout.CENTER);
f.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
} catch (ParserConfigurationException ex) {
ex.printStackTrace();
} catch (SAXException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} finally {
// Do our best to close the input streams
if (i != null) {
try {
i.close();
} catch (IOException ex) {}
if (jf != null) {
try {
jf.close();
} catch (IOException ex) {}
public static void main(String[] args) {
new LoaderTest();
}Thank you!1) I also think it's much better to keep your images separate from your XML, this prevents a lot of in case you just want to read XML data
2) What's exactly going wrong here? For the project.xml, make sure it's not inside a directory within the JAR file, or else the variable i will be null. Otherwise it looks fine.. -
Code ran fine in Eclipse, no output as a Jar file..help!
I have been working on a piece of code that reads an excel spreadsheet, and writes xml files based on that. (I'm to cheap to buy the numerous software out there)
The code ran beautifully in Eclipse, and all the right dialog windows and console outputs were present, as well as the final product, about 250 XML files.
I exported the src to a sealed jar file and ran it.
I get the first few dialogs that ask info of me, but as soon as it starts the process I get nothing!...
no exceptions, no errors, no xml...does anyone know what i did wrong?
Thanks so much for the help.we can't help you if we don't know the real probelm you've got.
use an error logger like log4j http://logging.apache.org/log4j/docs/index.html and report the exception messages. -
Help adding new files to Jar file.
I am new to Java and am having problems haveing our Web App work after I have recreated the JAR file...this is what I did...
Changed to the following directory at a dos prompt:
D:\jdk1.3.1_01\bin
Ran the following to extract the files from the jar file.
jar xvf app2.jar
...this created 5 directories with various files.
copied new and updated graphic files to
D:\jdk1.3.1_01\bin\app2\images
Recreated the jar file using the following command (pv com javavp meta-inf borland are the 5 directories that were extracted from the original jar file above):
jar.exe cvf app2.jar pv com app2 meta-inf borland
I now have a new jar file that is a similar size, so it looks good, but when I put it in our web site, it does not recognize certain frames (that get information from the database) that it did before (the frames are blank)
Any thoughts on what I am doing wrong?
Also, are there any Windows programs that i can use to make this easier instead of using the dos commands?
Thanks...To change the contents while inside a java program, you might be able to use Runtime.exec(String[]). Make the array with "jar.exe" as the first index, flags in the second, and remaining arguments in the remaining indecies.

My JAR file is not working properly!!!
Hi everyone,
I made an application that has a GUI (window). I converted it into a JAR file so I can send it to a friend by email. Then she can run it to generate the output. First, the user has to select a destination to save the .txt file (using JFileChooser). Then enters the inputs (using JTextFields). Clicks "Run" button (Results will be calculated and copied to the file). A Message will appear indicating that the results are copied. The problem is that when I run the application in the IDE (Eclipse) it works fine. But when I convert it into JAR, The moment I click the "Run" button, suddenly the window closes. Please HELP???
Thank youDrClap wrote:

Sorry guys, but i would like to make things clearer, As I mentioned earlier, What i'm doing is the following: 1) Using the Jfilechooser, save the results into a filename.txt file _[main class in the manifest file (class for the GUI) ]._ 2) Click "run" to write the data to the created file in step 1 [_another class is used to write to file_]. I have a feeling that the problem is related to the manifest main class. What do you think guys?I think your description of the problem is very bad. And I think your idea of making wild guesses is a bad way of diagnosing problems.
First of all. A JFileChooser does not save anything. It just allows the user to select a file to be saved to. So if you thought that the first step was writing anything or creating any file, you're probably wrong. But examining the code would help you understand.
Second, if you're having problems because one class chooses the file name and a second class writes data to it, then you're probably running into the basic beginner problem we see around here all the time of how to communicate data between objects. Again, examining the code might help.
Third, you need to understand what is writing that error message. Examining the code would help there too.
So: stop guessing. Look at the code.I'm still New To Java that's why i find difficulty in problems diagnosis. Regarding the JAR problem, as you mentioned, I used JFileChooser to select a file and (copying data) is the other part. So I will look at the code again.

How to retrieve constants value from compiled code in jar file?
Hi everyone,
I've been looking for a way to solve this for a week now, without any much success... and I've finally decided to ask the Java gurus for a solution! :-)
Here's what I am basically trying to do:
I have several jar files in which there are only compiled code (.class).
In every class, there are 2 constants (declared as static final String) that I would like to retrieve (one is the version and the other the date of the last modification).
My goal is to print a list of all the classes in the jar files with the values of these 2 constants for each class.
The solution that I have right now to do this does not work properly: for now, I read all the elements of the classpath, check if these are jar files, and if so, I look into each one and load all the classes one by one and print the results.
The problem with this is that it uses the method Class.forName(className) and as some classes are unfortunately present in many jar files (2 or 3 copies), once the classes have been loaded, then it won't be "reloaded".
Without the possibility to "reload" these classes, I cannot see inconsistencies in the versions of the classes present in the jar files.
I have read many articles, and I thought that I could then use a custom classloader and create a new instance of this classloader for each jar file.
2 problems with this:
- according to many posts in the different forums I have read, the jar files should not appear in the CLASSPATH (but this would be easier for me if I could use it...)
- some classes will not be loaded if some classes (present in other jar files) are not loaded... and this makes things really really complicated to implement...
So, I thought that I was maybe doing this the wrong way, and that there might be an easy way out of this...
In fact, I do not need to load the classes... all I need to do, is take a sneak peek at the constants and print their values... and that's it!
Somehow, I think that this is possible to retrieve the values of compile time constants (declared as static final String) as I can see that with Eclipse (when opening a jar file).
So, my question is: how can I do that within my java application?
Or maybe there is another easier solution to do what I need?

Can't open .jar file? (I have Lion)
I have written a program in Eclipse, and I exported it as a runnable jar to my desktop. But when I go and click on it I get this message:

Were you able to turn logging on, try the .jar again and then read the log?
I know nothing about Eclipse, but I do know there are many applications and web sites that are not Java 7 compatible. You will probably have to check with the developer and find out if Eclipse is and if an update is available or in the works. You will most probably need to have information from the Java log to submit to the developer. -

You downloaded the wrong thing if you wanted jar.exe. The J2RE d/l is the runtime only package, and doesn't contain the developer tools.
To download the current developer version of Java, go here:

OC4J: Class not found for class in jar file placed in \j2ee\home\applib\
I have an ADF application which uses external libraries (jars), which works fine when running the application from within JDeveloper (TP4).
However if I deploy the application to the embedded OC4J server it won't find any classes imported in those external libraries at runtime (deploy does work). E.g. one library class imports oracle.jbo.server.DBTransaction. If a method of this class is called I get the following exception:
Unexpected exception caught: java.lang.NoClassDefFoundError, msg=oracle/classloader/util/AnnotatedNoClassDefFoundError
oracle/classloader/util/AnnotatedNoClassDefFoundErrorThe same exception, when using a german locale, explicitely states that it cannot find oracle.jbo.server.DBTransaction.
The jar files are placed in the \j2ee\home\applib\ directory and a <library> element to this path is present in application.xml.
Any further hints what could be wrong?Hi Edwin,

Problem deploying connector: META-INF/ejb-jar.xml not found in jar file
Has anyone seen this problem:
I built Sun's Blackbox implementation and packaged
it identical to the BlackBoxNoTx.rar included with
Weblogic's 'jconnector' sample (even using the same
ra.xml and weblogic-ra.xml). When I try to deploy
it, the server reports:
java.io.FileNotFoundException:
META-INF/ejb-jar.xml not found in jar file
I have no idea why the server thinks my connector
is an EJB. If I deploy the BlackBoxNoTx.rar included
with the sample, everything works without a hitch.
The only variable that I'm changing in my BlackBoxNoTx.rar
is that I build the Blackbox classes myself--otherwise,
the RAR packagings are identical. Any assistance is
greatly appreciated since I'm banging my head against
a wall...
Thanks,
-jason
I was finally able to resolve this one. On the odd chance that someone else encounters
the same problem, here's what went wrong:
My RAR file had two directories: 'META-INF' and 'meta-inf'. The first was created
by the jar tool and contained the manifest.mf file. The second I created manually
and it contained my ra.xml and weblogic-ra.xml. When I examined the RAR using
any tools or I extracted the contents, it looked like it only contained one directory:
META-INF (because NT is case-insensitive).

Import JAR files (integrating JasperReports)
Dear all,
I'm using JDeveloper 11.1.1.3.0 on Windows 7 32bit.
I search this forum and I google a lot, but I couldn't find any workable solution.
I downloaded the newest version of JasperReport and iReport from the official website. I've done some tutorials from this site and everything seems to work fine.
Now I want to integrate JDev with JasperReports. I create new Fusion Web Application ADF, I get the properties of Model project, Libraries and Classpath tab, add Library and click New... I set the Library name as JasperReports, location as Project, check Deploy ad Default. I add to Class path every JAR files in E:\JasperReports\jasperreports-3.7.6\lib and to Source path the whole directory E:\JasperReports\jasperreports-3.7.6\src. I get sure that the Export is checked and I save all the changes.
I create a new Java Class JasperTest and I use this sample code:
import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.engine.export.*;
import java.util.*;
public class JasperTest {
public static void main(String[] args) {
String fileName = "test.jasper";
String outFileName = "test.pdf";
HashMap hm = new HashMap();
try {
// Fill the report using an empty data source
JasperPrint print = JasperFillManager.fillReport(fileName, hm, new JREmptyDataSource());
// Create a PDF exporter
JRExporter exporter = new JRPdfExporter();
// Configure the exporter (set output file name and print object)
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileName);
exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
// Export the PDF file
exporter.exportReport();
} catch (JRException e) {
e.printStackTrace();
System.exit(1);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}I cant compile this, it gives me Error(1,1): package net.sf.jasperreports.engine does not exist etc..
I cant import any class from JasperReports. Did I something wrong with importing the JAR files to my project ? Maybe I should set some system environment variable ? What else I can do ?
Any help will be appraciated.
Regards,
Wojtek.Hi,
I am also facing the same problem, I have few Jasper Reports which are closely integrated with my APEX applications, but for this i am using another application ( Jasper reports) which deployed in tomcat. This application hardly have 20 lines of java code, so i thought of embedding same in PL/SQL itself, But i am facing problem while importing JAR files i.e.
1. Where to put these JAR files so that i can import them in my PL/SQL.
2. I also tried using JAVALOAD function, but that also not worked for me.
Please give me some solution how to go about it??
