Jar files and Inner classes..

I am trying to compile a java source file of a class that has an inner class.. using GNU Make. I am not sure if the .jar file is packing properly, because I get an error :
Exception in thread "main" java.lang.NoClassDefFoundError: Airport$PortCode
        at Airport.getCode(Airport.java:133)
        at Airport.test1(Airport.java:228)
        at Airport.run(Airport.java:241)
        at Airport.main(Airport.java:255)where Airport.class is the main class and Airport$PortCode is an inner class of it (it is not static and is declared public)
it works when I use it via "java Airport" but again i get the above error when I run with "airport.jar"
thanks for you help

I tried to test it on UNIX, but it replied to my
commandUh, I am not so lucky to have a UNIX license (and don't see the need). Possibly the find on UNIX is different from GNU's find.
find: path-list predicate-listUse backticks: The output of the command between backticks is used as the value for the shell variable. Possibly it could be the case that your find program does not allow the omission of the path list, then just make it:
CLASSES=/home/here/there/project/classes
`find $CLASSES -name "*.class"`Execute this command and the output of the command executed can be used as a return value.
-name "*.class"look for all files ending on name.
You can always do:
$ man find (man is great)
or
$ info find>
>
>
JARCLS = `find -name "*.class"`

Jar files and Main-Class attribute

Sorry, I know there are other topics regarding this argument but none of them helped me solving my problem.
I've tried a thousand time in every possible way, but I still can't run my application from a jar file. I've got a package called client, whose main class is called Client. The package contains a sub-package called Icons. I've put everything into a jar file and added this manifest:
Manifest version: 1.0
Name: client/
Sealed: True
Main-Class: client.Client
But it won't work. I've tried to erase the Sealed part, I've tried "Main-Class: Client" and also "client/Client", I've tried putting into the jar the client directory and I've tried omitting it, but the answer is always the same:
Failed to load main-class header etc.
Can anyone help me? Please, I'm almost desperate!
Thanks

I've also tried to manually create a MANIFEST.MF file that only contained the following lines:

the same procedure with the addition of "Name: client/" before the main-class attribute generated the usual "Failed to load Main-Class manifest attribute" result. So now what?!? I'm getting crazy....

Jar files and Main-Class headers

I think I already posted this, but I can't find it on the forum...my apologies if it's already there and I'm just blind or something.
I have a bunch of classes in the directory C:/chess/server , and I want to make a .jar file with these classes. The class with the main method is server/ChessServer.class . From which folder should I create a jar file with these classes, and how exactly should I label the Main-Class header in the manifest file? Also, what's the purpose of the "Name:" header?
I know the topic is posted a lot, but I've tried many different ways and I can't get this to work. I get many variations on the "NoClassDefFoundError". I know the classes themselves are fine because they work perfectly when they're not in a .jar file.
Thanks in advance!

I tried that, and it still doesn't work. I used the command C:\chess> jar 0cmf manifest.mf MuChess.jar server . Manifest.mf is:
Main-Class: server.ChessServer
Sealed: true
When I try to run it with C:\chess> java -jar MuChess.jar , I get:

When I unpack the file with my excraction utility, I get get two folders: One is "server", and contains all the files it should--including ChessServer--, and the other is "META-INF" and contains the following MANIFEST.MF file:

Any ideas?

ANT - Jar File include another Jar file and importing classes

Here is the directory structure i have set up:
FTPGetter
\src
    \com
      \abc
        \ftpgetter
          - GUI.java
          - FTPGetter.java
          - Login.java
\classes
\include
    - ftpClient.jar
    - info.xml
\jar
    - FTPGetter.jarThe code compiles file and can create a Jar file without errors. But when I execute the Jar file, I get
java.lang.NoClassDefFoundError: com/abc/ftpclient/FTPwhich is a class that I import from the ftpClient.jar file in FTPGetter.java
What gives?
Here is my necessary build.xml code:

Clarification of JAR file and separate classes

Hi all,
I wanted to clarify a basic question. When do we club all classes to make a JAR file? For instance, in a web app with servlets, had all the servlet classes been put into a single JAR file, would that work? I know that woudn't but why?
Is JAR file like a single executable (.exe) file? So, when (which type of applications) do we need single JAR and when separate classes?
thanks much

Thanks, I've gone thru it. So, sounds like JAR file can be used for invoking app thru command line or from some other app or even running applet in a browser. It can not be used for a servlet or jsp application. Am I right?

Encryption/decryption through jar file and classes

Hi,
My application uses tomcat as web server.
I am doing encrytion and decyption.
i fetch encypted data from database and then decrypt it
If i use calsses in webapps -> WEB-INF -> classes folder, i place classes in that ,
In other case i use jar file and place that file in WEB-INF -> lib folder in the webapps directory.
There is huge performance difference.
While using classes performance is great while using jar file performance is very disappointed.
I am using a file for encryption /decryption also.

Are you getting any error messages? Have you put debugging code in those classes to see what is happening?

JRockIt Deleting JAR files - Error loading class

Hi there,
Customer is facing a very weird issue. Their application has an application that contains some EJBs and Web applications that, apparently for no reason, it starts to unload classes and delete JAR files and WAR files from the Weblogic's "extract" directory. If I bounce the application, everything starts working fine until a moment where the issues starts again.
I thought this was any kind of memory issue that was not allowing the JVM to free enough resource for loading the classes again after unloading it. But we gave enough memory for the JVM and it stills happening.
Thoughts? Any idea that might help us on troubleshooting is very welcome at this time.
Thanks in advance,
Davi

Error while using .jar file instead of class file.

Hello friends,
I created a java class which are referred and called from other jsp\xml and java files. I compiled this java class and everything is working properly. However, I do not want to use class files but want to use jar files instead. So, I created a jar file of this class file by using the command "jar -cvf jarfilename.jar".I kept the jar file in its respective folder .Also, I removed the class file from its path, just to see that the jar file will work automatically.
Unfortunately, I am getting an error:
java.lang.RuntimeException: Component.createComponent(...) Component class not found: <java class path>. I also tried giving the path of this jar file in the classpath. This also does not seem working.
How to solve this problem?
Thanks,
Ranjith M.V
Edited by: RanjithM.V on May 11, 2008 10:34 PM

You probably populated the jar file incorrectly.
A common mistake is to include the path that you had on the classpath, in the jar file.
So a person will have a classpath like this: /foo/
And a class in a package bar, like this:
package bar;So that other classes would include the file like this:
import bar.TheClass;And the class file is on the filesystem like this:
.../foo/bar/TheClass.classThen they'll create the jar file including the foo directory, so if they list the jar's contents, they'll see the above (/foo/bar/TheClass.class). But this is wrong. It should start off so that the jar entries start with the top-level package names (like /bar/TheClass.class).
Maybe you've done that.

JAR files and J2ME

Just starting a J2ME project.
An embarrassingly Noobie Question:
1) All the classes that are supposedly "built-in" to my device (phone)
do NOT need to be included in the deployed JAR file, right?
2) Anyone know how to do that in Netbeans 5.0?
Project -> Properties -> Build shows sources filtering
but that doesn't include anything from my "input"/library .JARS.
However, all the com.*, javax.* and java.* files are being included in
my output JAR file and it causes failures in preverify and loading
on the phone.
HELP!!

hi,
any know this question
please send me the procedures about how load my J2ME

please anybody known this answer reply very soon.
thanks a lot

Preverify and inner classes

Hi. I'm trying to use a makefile to reduce build time for my project. The way it works:
1. compile all the altered .java files
2. preverify all of the replaced/new .class files from step 1 -- each individual file by file.
However, I've run into a serious stumbling block. Some of my .java files contain inner classes. Step 2 works perfectly on all of the main .class files. But it simply skips the inner class .class files. I tried it manually and it had the same effect.
Here is the command line (altered for confidentiality, but effectively the same).
preverify -classpath "h:\\j2mewtk\\lib\\midpapi.zip;blahtmp" -d blahclasses foo.bar.baz.Foodle$FoodleFun
This does not produce the desired output in blahclasses--it produces nothing! I'd really appreciate it if someone could tell me what to do. Is it ignoring everything after the $ sign?
--Impulse.

OK, well, I solved it myself. Turns out that I needed to get my makefile to replace every '$' with '\$', and then it worked perfectly.
So I'm giving all my Duke Dollars to myself grin

Hi,
I found it in ADF 11g R2 documentation - http://docs.oracle.com/cd/E24382_01/web.1112/e16182/taskflows_regions.htm#insertedID10
I guess this is 11g R2 feature.
I have a requirement to display the multiple regions dynamically. This feature suits my requirement perfectly, but unfortunately it is not available in 11g R1.
Can we achieve the similar functionality in 11g R1 through other means?
Thanks

Jar file required for class

Hi folks
i need to know the IBM's Jar file and download the same which consists of following Classes.
com.ibm.connector.ConnectionSpec
com.ibm.connector.InteractionSpec
com.ibm.connector.ConnectionSpecManagementProperties
com.ibm.connector.InteractionSpecModeProperties
I know these classes are part of CCF Framework.
please let me know at earliestTime . am need of this info.
Regards
Ram

Thanks for your info.
But the article uses javx.resource.cci.CoonnectionSpec class,(J2EE Connector Architecture) But I need to get info about com.ibm.connector.CoonnectionSpec(CCF old one)
(It's part of Enterprise Access Builder).
I need to know the exact jar File(which is having above mentioned Class file) and where to download the same.
But I still need a old one as part of our implementation.
Awating for your reply.
Thx
Ram

Help with creating jar file and running it ?

Hey guys,
I have a program with a package called classes and a sub-package called classes.mainLib.
I am trying to create a JAR file of the class files in mainLib. There is only one class file in classes and that contains the main method. So this is what i am doing:
1. create a manifest file with: Main-Class: classes.Cars
2. from within the mainLib directory (./program_name/classes/mainLib/) i do this:
jar cvf mainLib.jar manifest ./*.class
3. Then i move this jar file to ./program_name/lib and change directory to ./program name/
4. try to do this: java -jar ./lib/mainLib.jar
But it errors with:
gary@linuxbox:~/java/cars$ java -jar ./lib/mainLib.jar
Failed to load Main-Class manifest attribute from
./lib/mainLib.jar
Any ideas why this is happening. the manifest is included in the jar'ing
Thanks.

At a glance, it looks like you are placing only the
class files in the jar and trying to navigate your
classpath to run it. Instead, you have to place ALL
the package folders into the jar from the root of
your package hierarchy and the jar runs anywhere, in
any folder. The packages are INSIDE the jar.
also I see cars/classes in a path you describe ...and
the program seems to wnat classes/Cars ??? Could
this be an additional issue (or am I missing seeing
something about your package structure)?Firstly, i believe all my spelling and cases are correct.
I have the following strcuture:
Cars.class (contains main) : package classes in ./classes directory
All other classes : package classes.mainLib in ./classes/mainLib
I would like to jar ALL files in mainLib but not the class that contains the main method. Is this possible?
I'm not sure how clear i was earlier, hope this is more understandable.

How to Add JAR files and Config files to CLASSPATH at runtime?

QUERY:
During runtime, I need to load the JAR files and relevant config files( .cfg files and .properties file) into CLASSPATH and run a specific java program from one of the JAR which is available in CLASSPATH.
Please advise me any relevant Java API details or a sample java program to implement the above use case.
Thanks in advance.

You don't add to YOUR classpath once your app is launched.
You create a NEW process for the app you want to run and provide the proper environment for it to run in - including any PATH or CLASSPATH environment variables.
The Java API for the ProcessBuilder class has a simple example that shows how to create the arguments and launch an external application.
ProcessBuilder (Java Platform SE 7 )
There are also PLENTY of other examples of using ProcessBuilder; just search the net.
