Adding manifests to Jar files using different versions

I have been using the following to add a manifest pointer to my main class called JTiming
C:\jdk1.1.8\bin\jar cmfv MyMainClass.txt JTiming.jar *
and it works a treat, when I unjar the jar and look at the manifest file it includes the pointer to JTiming and lists each file jarred. When I try it with JDK1.3.1 or JDK1.4.1 jar.exe's they both fail to create the correct manifest entries. I can't see any notice of a change to the command line ooptions for the jar.exe's for these newer versions what am I missing?

You seem to misunderstand - if you look at the command line I wrote in my original posting, I do exactly what you suggest!! I am able to include a reference to my starting class, my problem is that I appear to be able to get my own manifest inclusion using 1.1.8 jar.exe, but not using the jar.exe from 1.3.1 or 1.4.0

Adding jar file in my gerareted jar file using netbean 4.0

Hi,
I write an application de process XML file using JDOM. I add the JDom package jar file to my project and everything work fine. But when I generate, my project jar file using netbean 4.0, my generated jar, is not working with the XML files anymore. Everything seems like it didn't include the JDOM jar file?
Thanks for any help to fix the problem.

I find that you can not use command-line such as java -classpath add classpath
it can not work, I use netBeans4.0 i don't whether because of netbeans or java itself.
you can add classpath in jar's Manifest.mf file
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.2
Created-By: 1.5.0_01-b08 (Sun Microsystems Inc.)
Main-Class: chat.Main

Can i load a class in subdirectoy inside a jar file using applet tag?

hi every one.. thank you for reading ... i am really in dire need for the solution..
my problem is that i have a jar file contianing a package which inturn contains my applet class...
i am trying to access this applet class using a applet tag in html file. this html file is in same directory as the jar file. i am having no problems in windows but when i am doing this in linux apache server i was getting class not found exception. (already checked the file permissions). and when i am successful when using simple package directory instead of jar file . so gist of my quesition is "can i load a class in subdirectoy inside a jar file using applet tag in a html file"?

When you tested in Windows were you using Internet Explorer? On Linux you will be using a different browser, usually Mozilla of some version, or Firefox. Note that the HTML tags for applets will be different between the browsers if you are using the object tag. Principally the classid value for the object tag will differ between Firefox and Internet Explorer.

Making jar files using API

hello!
I m trying to make a jar file using the API. When the jar tool is used for the same manifest file, it is correctly written and an executable jar is created. When I use the API, the jar file is made but it is nor executable. Here is that part of code:
jar = new File(parent, jarName);
System.out.println("Executing jar command...");
//create jar file here
Manifest mf = new Manifest(new FileInputStream(manifest));
fos = new FileOutputStream(jar);
jos = new JarOutputStream(new BufferedOutputStream(fos), mf);
BufferedInputStream reader = null;
byte[] data = new byte[BUFFER];
int byteCount = 0;
for(int i = 0; i < fileNames.length; i++)
System.out.println("Adding " + fileNames);
FileInputStream fis = new FileInputStream(fileNames);
reader = new BufferedInputStream(fis, BUFFER);
JarEntry entry = new JarEntry(new ZipEntry(fileNames));
jos.putNextEntry(entry);
while((byteCount = reader.read(data,0,BUFFER)) != -1)
jos.write(data, 0, byteCount);
}//end while
reader.close();
}//end for
jos.close();//close jar output stream
fos.close();
I m sure someone will be kind and intelligent enough to solve the problem. Thank you!

A jar file is simply a Zip file. So the two API's are quite similar. First, you create a CRC - that is a way to make sure that the file isn't corrupted and that all the bytes are there (it's a polynominal algorithm that returns a number which is written in the Zip(Jar) file as well). Each entry is a file or directory. Before writing any data to the Zip(Jar) file, you have to write info on the actual file (like name, path, length etc). That's why you use putNextEntry(). Each file can have it's storing methods, although the most common is to use the "default" methods (built in the ZipOutputStream/JarOutputStream)
But in this example you set the storing methods on the entry. You use the setMethod() method to switch between either storing or compression (don't know why, but in this example you don't compress the file - you should). I myself don't use the setSize() and setCompressedSize() methods at all (and it works fine). Don't know exactly what are the implications of using them. Neither do I use the setCrc() method (If I think a little, I've only used this API once - I don't use it that much), but it's quite straightforward. It's used to check that the data is ok, and since the CRC number is the result of an algorithm, it needs to know the bytes of UNCOMPRESSED data: that's why you use crc.update() on the bytes. After that you actually write all the info set before to the Zip (Jar) file using putNextEntry(). But remember that a ZipEntry doesn't have any data. You'll have to write it yourself: thus the need for the write method: Here are two small programs I used for Zipping and Unzipping. Changing them to work for Jar files is extremely simple:
//Zip.java

Multiple jar files from different locations

Hello,
I am having an applet that access code from two different jar files. Of them one is a common jar file for many applets. So I couldn't place it in the local dir as that of the applet's html. I am not using any web server.
     Just to give you a feel of it :
     <PARAM NAME = archive VALUE = "DVApplet.jar,DVVP.jar" > are the jar files my applet is dependant on. But DVVP.jar has to be accessed from a dir different from local dir.
     Will be glad if someone can throw some light on accessing different jar files from different dirs.
     Thanks for your time.
Regards,
Anantha

You can use a class loader to do such things.

Append to jar file using java codings

Hi,
I have codings which could create jar file and write datas in it. but i need to append datas to existing jar file using java codings.Here i have attached my codings which will write datas to new jar file. when ever i use this my existing contents gets overritten. wat can i add to this to append.
FileOutputStream stream = new FileOutputStream(archiveFile,true);// archive file is jar file name
     JarOutputStream out = new JarOutputStream(stream, new Manifest());
JarEntry jarAdd = new JarEntry(tobeJar.getName()); // tobejar is a file to write in jar.
jarAdd.setTime(tobeJar.lastModified());
               out.putNextEntry(jarAdd);

in.read(data); // read data for this old entry
in.closeEntry();
out.putNextEntry(outEnt);
out.write(data); // copy it to the new entry
out.closeEntry();
// now write an entry for the file we want to append - this is the OP's code
JarEntry jarAdd = new JarEntry(tobeJar.getName()); // tobejar is a file to write in jar.

while (true) {
int nRead = in.read(buffer, 0, buffer.length);
if (nRead <= 0)
break;
out.write(buffer, 0, nRead);
out.closeEntry();
// and *now* we close the new JAR file.
out.close();
// We then delete the old JAR file...
new File(oldJarName).delete();
// ... and rename the new JAR file to use the old one's name.
new File(tempJarName).renameTo(new File(oldJarName));

How to export swf file in different versions of flash like (6,7,8,9) ?

Hi,
    System Specification :
    -XP with SP3
    -MS Office 2003
    -Flash V.10
    -Xcelsius Engage 2008 ( 5.3.0.0 )
    -Xcelsius Build number 12,3,0,670
   When I export output in swf format then xcelsius generating swf file of version 9. I want to export swf file in different versions of flash like (6,7,8,9) . I tried to install older versions of flash to do this but I am not able to open xcelsius in older version. I am getting error saying 'Install latest flash player'.
Is there any way to export swf files in different versions?
Is this build is compatible with only flash 10?
Thanks,
Ganesh

Xcelsius only support Flash version from 9 on. There is no way to export to 6,7 or 8.

Accessing the same database file using different handles/cursors

Will there be any problems accessing the same database file using different DB handles in a transactional environment? We have implemented a process which have multiple transient threads coming up and initiating DB opens and read/write operations to the same database file using different handles and cursors?
Can this potentially create any problems/bottlenecks? Can someone suggest the best way to deal with this scenario?
Thanks in advance.
SB

Hi,
Berkeley DB is well suited to the scenario you describe. You need to ensure that Berkeley DB is configured correctly for transactional access, the best information describing the requirements is in the Reference guide here:
http://download.oracle.com/docs/cd/E17076_02/html/programmer_reference/transapp.html
If there will be multiple threads operating concurrently, then you will need to design your application to detect and deal with deadlock situations.

How to run test cases in a jar file using junit?

Hi,
I want to run test cases in a jar file using junit and the jar file is not in the class path. I wrote the following code, but it does not work.
import java.net.URL;
import java.net.URLClassLoader;
import junit.framework.TestResult;
import junit.textui.TestRunner;
public class MyTestRunner {
     public static void main(String[] args) throws Exception{
          URL url = new URL("file:///d:/case.jar");
          URLClassLoader loader = new URLClassLoader(new URL[]{url});
          loader.loadClass("TestCase1");
          TestRunner runner = new TestRunner();
          TestResult result = runner.start(new String[]{"TestCase1"});
          System.out.println(result.toString());
}Any ideas?
Thanks a lot.

Wouldn't it just be easier to put it on the classpath? You're trying to, anyway, with a URLClassLoader, albeit in an entirely unnecessarily complicated way

Create BPEL jar file using Bpelc via Java classes

HI,
I am trying to create the BPEL files ( xyz.bpel, bpel.xml, xyz.wsdl etc.. ) on the fly using Java code... Once I create all these files, I create a packaged jar (Ex : bpel_xyz_v2006_10_17__37256.jar) file and deploy the same in the Bpel PM.
Right now, in order to create the jar file, I am running the bpelc.bat file under bpel/bin and then using the IBPELDomainHandle, I am deploying the process.
But my requirement is to create the jar file using java rather than executing the bpelc.bat file..
Can you please give me pointers as to how to achieve the same?
Thanks
Pramod

Actually, I had figured out the part of calling the Bpelc class, but initially I was trying to create an object of the class and was not able to do so. That was where I got stuck.
Eventually, I did something like the code snippet below and it works fine and the jar file is created. Just fyi for anyone looking in the future.
String[] setupValues;
setupValues = new String[]{ "-home", "D:\\product\\10.1.3.1\\OracleAS_1\\bpel", "-rev",
"1.0", };
Bpelc.main(setupValues);
Thanks
Pramod
