Call class inside a jar file??

Hello group,
I have a class with a main mathod and this class is inside a .jar file. This jar file reside under my
web-inf\lib or class-path directory in my application at Weblogic Server.
How can I call this class by command line?
I have to create a cliente to do it?
Is it possible? IÂ´m having problems because the weblogic server is using the jar file at the same time that I trying use it calling by command line.
Where can I find more information?

Hi I have an executible JAR file that I can call from command line by using the command - "java -jar file.jar".
Is there a way for me to call this JAR file inside a Java class in another Java Program?There can be more going on in a jar than just as a container for classes.
The manifest defines the behavior. So to replicate the behavior you must do exactly that.
As an example of that.
[http://java.sun.com/developer/Books/javaprogramming/JAR/basics/manifest.html#download]
Additionally by running it in your application you must consider what the scope of that is. If you just load the classes directly then they will be in the system class loader and thus cannot be unloaded. Using a class loader solves that.

Include and call an .exe file inside my jar file

Hi.
I want to include an exe file and call it inside my jar file. this is the code.
InputStream is = getClass().getResourceAsStream("/native/my.exe");
          int[] line = new int[is.available()];
          File myFile = File.createTempFile("my","exe");
          myFile.deleteOnExit();
          myFile.setExecutable(true);
          FileOutputStream out = new FileOutputStream(myFile.getAbsolutePath());
          int i = 0;
          int c;
          while((c=is.read()) != -1){
               line=c;
               i++;
          is.close();
          for(int j= 0;j<line.length;j++)
               out.write(line[j]);
          out.close();
So i store it in my temp folder. Than i run
String myFileLocation = myFile.getAbsolutePath();
p = rt.exec(myFileLocation);
Everything goes fine, but the behaviour of the .exe file is not the same. I mean when i run the commands
PrintWriter writer = new PrintWriter(p.getoutputStream());
writer.println("command");
the behaviour is not the same. What goes wrong.

But to load the xml file I need to create a File objectIf this is true then you will not be able to load the XML file, since a jar entry is not a File object and cannot be represented as one.
However if you get rid of whatever it is that loads your XML file and replace it by more standard JAXP processing, you should be able to parse an InputStream that reads from the jar entry. You know how to get that so it should not be a problem.

JRE doesn't find the main class inside a JAR archive file

Hello everybody,
I've written a small application in Java, using NetBeans. Running my application inside NetBeans works fine, but I can't run it from the console or by double clicking the jar file.
Running it from the console I get the following error message:
java -jar TestApplication.jar
Exception in thread "main" java.lang.NoClassDefFoundError: tst.Benchmark
   at gnu.java.lang.MainThread.run(libgcj.so.81)
Caused by: java.lang.ClassNotFoundException: tst.Benchmark not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:TestApplication.jar], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
   at java.net.URLClassLoader.findClass(libgcj.so.81)
   at gnu.gcj.runtime.SystemClassLoader.findClass(libgcj.so.81)
   at java.lang.ClassLoader.loadClass(libgcj.so.81)
   at java.lang.ClassLoader.loadClass(libgcj.so.81)
   at gnu.java.lang.MainThread.run(libgcj.so.81)I know that these errors often come when the class path is not set in the right way, and using a single java file, you can fix this by passing the parameter "-cp ."
I tried this with the jar file but it does not work and using "-cp TestApplication.jar tst/Benchmark" didn't work either.
Inside the jar file I have the META-INF Folder and a "tst" Folder which contains all my class files. And I've set tst.Benchmark as the main class, this also stands in the manifest file correctly.
Do you have any ideas what could be wrong?
Greetings JavanianGuy

This line
at gnu.java.lang.MainThread.run(libgcj.so.81)says that you're using GNU's Java, not Sun's Java. They are not the same. GNU Java is incomplete.
You'll need to ask this question at the GNU Java site.
Recommendation: Use Sun's Java

Is it possible to call a class in a jar file from JNI environment?

Hi
Is it possible to call a class in a jar file from JNI environment?
Thanks in advance.

Could you explain a bit more what you are trying to do? (In other words, your question is vague.)
o If your main program is written in C, you can use JNI to start a JVM, load classes from the jar of your choice, and call constructors and methods of the objects defined in the jar.
o If your main program is java, and has been laoded from a jar, a JNI routine can call back into java to use the constructors and methods of classes defined in the jar(s).

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.

Can I create a JTA EntityManagerFactory in a utility class in a .jar file?

I have utility classes in a .jar file inside of a .war file deployed in Glassfish 3.1. One of these utility classes, CredentialsUtil, needs to access a database. I can't inject an EntityManager into CredentialsUtil since it is not an EJB. (For security reasons I don't want to make CredentialsUtil an EJB. I want it to be a POJO.)
In CredentialsUtil I need an EntityManagerFactory that is connected to a datasource defined in Glassfish. Here is the line from CredentialsUtil.java and from the persistence.xml both of which will be in the util.jar file:
EntityManagerFactory emf = Persistence.createEntityManagerFactory("Credpu");
<persistence-unit name="Credpu" transaction-type="JTA">
I can't use RESOURCE_LOCAL since any changes to the datasource configuration must be done in Glassfish rather than changing persistence.xml.
(The transaction context is not important in CredentialsUtil. It will be called by a WS-Security handler which may not have a transaction context.)
Can I put the persistence.xml and the CredentialsUtil class that creates the EntityManagerFactory from it inside of the util.jar file (which will be in a .war), or do I have to move the class and a copy of the persistence.xml file out to the .war file? (I'll have to leave persistence.xml in the .jar file too since there are some @Entity in the .jar file. I don't know why but there are @Entity pojos in the .jar file.)
I'd like to use the existing persistence.xml, but if I can't is there is a way to create an EntityManagerFactory (or EntityManager) that gets its datasource directly from Glassfish, ignoring persistence.xml?
Thanks.

Styles in Pages are saved in the documents (or templates). There is no easy method for adding a style to a built-in template (and it is strongly recommended that you do not tamper with them). You can open a built- in template, add your style and save it as a user template so that your new style will be standard in documents created from that template.

Accessing classes in external jar files

I have a jar file called main. I want it to be able to acces the classes in another jar file say test.jar how do i do this.
Thank you

ok, if i have this right...
you have 2 directories that hold 2 .jars, right?
plugins/ -------- build/plugins .jar
systemModuals/ ------- DiaryUI and Loader .jar
Your main JAR is diary?
Diary.jar
you want Diary to run with the jars inside plugins and systemmoduals?
you set the "class-path:" tag like this....
write this manifest file. save it as Manifest.txt and put it in your home dir.
Main-Class: YourMainClass
Class-Path: Diary.jar plugins/this.jar systemmoduals/diaryui.jar
<make sure to hit enter, go to the next line>
command line to your parent directory.
jar cmf Manifest.txt Diary.jar build/main/*.class
you should be set to go.
use
jar xf META-INF/MANIFEST.MF
to read the present manifest that netbeans has created
if necessary

java -jar MyJar.jarYou need to set the Main-Class attribute in the manifest, though.

Open MPlayer OSX and show the playlist (command-shift-p) then drag the file into the playlist. Click the file in the playlist and click the "i"nfo button. What does it list for file, video and audio format?
Not all of the codecs used in avi and wmv files are available for OS X so I'm guessing your file happens to be using one that isn't...

How to read, write file inside the JAR file?

Hi all,
I want to read the file inside the jar file, use following method:
File file = new File("filename");
It works if not in JAR file, but it doesn't work if it's in a JAR file.
I found someone had the same problem, but no reply.
http://forum.java.sun.com/thread.jsp?forum=22&thread=180618
Can you help me ? I have tried this for all night !
Thanks in advance
Leo

If you want to read a file from the JAR file that the
application is packaged in (rather than a separate
external JAR file) you do it like this ...
InputStream is =
ClassLoader.getSystemResourceAsStream("filename");Better to use
this.getClass().getClassLoader().getResourceAsStream();
From a class near to where the data is. This deals with multiple classloaders properly.

How to include the inner classes in a jar file in netbeans ide

Dear java friends
how to say to netbeans ide that it has to include the
inner classes in the jar file.
(i have one single applet class
with two inner classes that show up
in the build/classes file but not in the jar).
The applet works in the viewer but not
in the browser (I believe because the
xxx$yyy etc should be in the jar)

First, please stop posting the same question multiple times:
Duplicate of http://forum.java.sun.com/thread.jspa?threadID=5269782&messageID=10127496#10127496
with an answer.
Second, If your problem is that you can't do this in NetBeans, you need to post to somewhere that provides NetBeans support - like the NetBeans website's mailing list. These forums do not support NetBeans (or any other IDE) - they are Java language forums.

A .dll inside a .jar file

Hello,
I want to place a .dll inside a .jar file ? It's possible, What is the library.path setting: the jar file or the path where the dll is put is in the jar file; and the argument of the System.loadLibrary?
Thank for all

Hello,
I want to place a .dll inside a .jar file ? It's
possible,Of course, you can put any type of file you want into a jar file.
What is the library.path setting: the jar
file or the path where the dll is put is in the jar
file; and the argument of the System.loadLibrary?You cannot do a System.load() or System.loadLibrary() on something in a jar file.
You have to first extract the dll to the filesystem. Then if you put it in the library path you can use System.loadLibrary(). But I think it is easier to use System.load() as you know the complete path to where you put the dll and can just supply that to System.load().
