Adding Jar files in another Jar file

Hi,
I have a very bad problem. Please some one help me here.
I created a Java application which is organized in a package structure.
The directories and files in the JAr files are following
1) TestApplication.class - The application startup class.
2) com(dir) - The start of my package structure, all the othere files are in this directory
3) config (dir) - Directory containing all the configuration files.
4) hsqlDatabase (dir) - contains the inprocess database
5) images (dir) - Contains all the images used in the application.
6) lib (dir) - Contains all the other jar files that i use in this application, i have about 10 of them in this directory.
I created a jar file which contains all these dir and the TestApplication.class file. I also uses the 'Main-Class' and 'Class-Path' attribute.
This is my META-INF\MANIFEST.MF file
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.1
Created-By: 1.4.2_03-b02 (Sun Microsystems Inc.)
Built-By: jj
Main-Class: TestApplication
Class-Path: .;./lib/commons-codec-1.3.jar;./lib/commons-httpclient-3.0
-alpha1.jar;./lib/hsqldb.jar;./lib/kunststoff-2_0_1.jar;./lib/kunstst
off.jar;./lib/liquidlnf.jar;./lib/log4j-1.2.8.jar;./lib/looks-1.2.2.j
ar;./lib/jcalendar.jar;./lib/mysql-connector-java-3.0.9-stable-bin.ja
r;./lib/ViolinStrings.jar;./config;./hsqlDatabase;./images
When i try to run the application through
java -jar xxxxx.jar
1) the first problem is that it starts the application (TestApplication.class) and also loads the rest of the application in my package(com\...). But it cannot find the classes which are in the jar file (in the lib dir).
2) I am also trying to read from a config\xxxxx.properties file, but i get an exception showing FileNotFound (xxxxx.properties).
Hope that this will help you to help with my problem,
Thanks in advance,
Jobby

1) the first problem is that it starts the
application (TestApplication.class) and also loads
the rest of the application in my package(com\...).
But it cannot find the classes which are in the jar
file (in the lib dir).
jars inside of jars do not work like you want them too. You should be able to write a class loader that can find those other jars, but Java does not directly support jars inside of jars. Of course, you can unjar the other jars and use them as well.
2) I am also trying to read from a
config\xxxxx.properties file, but i get an exception
showing FileNotFound (xxxxx.properties).
Is this file also in the jar? If it is, you need to use getClass().getResource() to find the file.

Executing .jar files from another .jar file.

How would I run one .jar file from another .jar file. and is there anyway to call specific class arguments? Because I have one .jar file that reads a specified file and returns its contents.
So how would I execute it and specify its arguments and how would I make it return something to the executing jar file?

Because I have one .jar file that reads
a specified file and returns its contents. Presumably you have a class that does that, and you have that class stored in a jar. And you want to know how to... um... do something with that class. I say "um..." because normally you don't execute a class, either, you either call its static methods or you create an instance of the class and call its instance methods.
If you have been writing a whole lot of little classes each of which just has a static main method, then stop doing that. Write real Java classes instead. The tutorial is here:

How to Include a ZUL file in another ZUL file

Hi
I need to Include a ZUL file in another ZUL file
which is not in same JAR. Both are in different JAR.. but i want to Include that...!
Thanks...!

You want to include a ZUL file, whatever that is, that's in one JAR inside another ZUL file that's in another JAR? I don't even understand the question. Get it out of the first JAR and include it inside the 2nd ZUL file ???

Copy one text file to another text file and delete last line

Hi all wonder if someone can help, i want to be able to copy one text file to another text file and remove the last line of the first text file. So currently i have this method:
Writer output = null;
         File file = new File("playerData.xml");
         try {
               output = new BufferedWriter(new FileWriter(file, true));
               output.write("\t" + "<player>" + "\n");
               output.write("\t" + "\t" + "<playerName>" + playerName + "</playerName>" + "\n");
               output.write("\t" + "\t" + "<playerScore>" + pointCount + "</playerScore>" + "\n");
               output.write("\t" + "\t" + "<playerTime>" + minutes + " minutes " + seconds + " seconds" + "</playerTime>" + "\n");
               output.write("\t" + "</player>" + "\n");
               output.write("</indianaTuxPlayer>" + "\n");
              output.close();
              System.out.println("Player data saved!");
         catch (IOException e) {
               e.printStackTrace();
          }However each time the method is run i get the "</indianaTuxPlayer>" line repeated, now when i come to read this in as a java file i get errors becuase its not well formed. So my idea is to copy the original file, remove the last line of that file, so the </indianaTuxPlayer> line and then add this to a new file with the next data saved in it. So i would end up with something like this:
<?xml version="1.0" encoding="UTF-8"?>
<indianaTuxPlayers>
     <player>
          <playerName>Default Player</playerName>
          <playerScore>0</playerScore>
          <playerTime>null minutes null seconds</playerTime>
     </player>
     <player>
          <playerName>Default Player</playerName>
          <playerScore>0</playerScore>
          <playerTime>null minutes null seconds</playerTime>
     </player>
     <player>
          <playerName>Default Player</playerName>
          <playerScore>0</playerScore>
          <playerTime>null minutes null seconds</playerTime>
     </player>
</indianaTuxPlayers>
However after all day searching the internet and trying ways, i have been unable to get anything working, could anyone give me a hand please?

I would go the XML route too, but for fun, open a file as a BufferedWriter and do this:
void copyAllButLastLine(File src, BufferedWriter tgt) throws IOException {
    BufferedReader in = new BufferedReader(new FileReader(src));
    try {
        String previous= in.readLine();
        for (String current = null; (current = in.readLine()) != null; previous=current) {
            tgt.write(previous);
            tgt.newLine();
    } finally {
        in.close();
}

Pages Importing from pages file to another pages file

Is it possible to Import from a separate pages file to another pages file
IF so HOW?????

Tulse, I'm using Pages 2 too. The first thing I'd tried this on had only a simple drop cap in a text box, fixed on page. That didn't copy - or at any rate didn't paste. The text box had been sent back to overlay it with inline spaces to clear the capital. These reproduced, but the capital didn't. Neither did kerning or baseline adjustments, nor my inserted guides for "leading" the text to the same depth on every page
Also page set-up details were not transferred in this way: i.e., if you change the margins in a template (even the blank one) the margins don't transfer. Logical enough, page set-up belongs to the document, not the section.
Looking at this again, in the Extreme Newsletter template, imported graphics transferred, and inserted text transferred, but layering and placement information did not. I'd made my own pages by altering this, generally using text boxes or shapes to compose picture pages rather than using those in the template. But the copied and pasted sections were all over the place.
So it may be the case that if you're copying from a section to a document with identical layout, page set-up & etc. to the one you're copying from, the result will contain most of the content. But the layering, placement on page of fixed objects, etc., would seem to be decidedly iffy.
I've tried it on title page sections, where the info in fixed text boxes copied, but neither their placement nor relative placement, and (in the newsletter template) with both my own and the provided sections, with no consistent results. If it works in some cases, then that would be handy.
It's easy enough to try, and undo if it doesn't work.
But it's certainly no subsitute for being able to insert one Pages document into another; nor even always bits of it. I'd be inclined to conclude that copying and pasting in this way uses something less than the full Pages file format.
Cheers.

Insert pdf file into another pdf file keeps getting stuck

I am trying to insert a 5 page pdf file into another pdf file (both unsecured) and it keeps getting stuck at about 71%* conplete. I can't even get the file to show up on the screen so i can close it. Help?

I have tried several different files, and get the same phenomenon with each one –
1.     I open an acrobat file.
2.     I open a WORD file.
3.     I copy a sentence from WORD to the clipboard.
4.     I click on View in Acrobat, Tools, Pages, other options, insert from clipboard.
5.     Acrobat shows that it is copying, and when it gets to 67% it stops and runs and runs and then only way I can stop it is to go to the task manager and end task.
I tried refrying with a file and that didn’t work, and I can’t imagine that Acrobat was designed so that each time I try to insert from WORD I would have to refry (even if it did work).
Please help!
Thank you

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:
<?xml version="1.0"?>
<project name="FTPGetter" default="all">
<property name="src.dir"        value="src"/>
<property name="package.name"   value="com.abc.ftpgetter"/>

<property name="run.classname" value="${package.name}.FTPGetter"/>
<target name="init">

        <fileset dir="${include.dir}">

        <attribute name="Class-Path" value="include/ftpClient.jar"/>
      </manifest>
    </jar>
</target>

nevermind I got that fixed now:
had to get the build.xml code for the <target name="jar" depends="compile">so that it looks more like:
<target name="jar" depends="compile">
    <jar jarfile="${jar.dir}/FTPGetter.jar">
      <zipfileset dir="classes" prefix="" />
      <zipfileset src="include/ftpClient.jar" />

      <manifest>
        <attribute name="Main-Class" value="com.abc.ftpgetter.FTPGetter" />
      </manifest>
    </jar>
</target>Keyword would need to be zipfileset.

Import location in wsit-client.xml to file in another jar

Normally the wsit-client.xml has import statements like this:
+<import location="foo.xml" namespace="http://foo.org/" />+
I've found that their can be online 1 wsit-client.xml on the classpath/META-INF, but can I refer to an xml who's located into another jar in that wsit-client.xml? Something like :
+<import location="classPathResource/WEB-INF/foo.xml" namespace="http://foo.org/" />+
I would like to create a single wsit-client.xml who contains the imports for all my webservices but I want to separate the configuration for all the different webservices in to different projects.

ApplicationClientInitialcontextFactory class is generally used with thick clients [A java swing client.] The client is bundled as a jar and application-client.xml is placed under the META-INF of the archive.
For JSP clients you can try using com.evermind.server.rmi.RMIInitialcontextFactory to lookup the beans.
[You can also tty placing the application-client.xml under a META-INF folder in the deployed JSP application root folder eg: j2ee/home/applications/MyApp/META-INF/application-client.xml]
hope that helps

Setting Classpath so one jar can access another jar

I am having trouble with running an application as a jar that accesses other custom libraries.
I have made a small example to try to get this working.
I have
     HelloWorld.class - that prints out "HelloWorld" and then throws a custom exception JWIException
     JWIException - exception that is in a package com.jeffersonwells.util
I have put the JWIException class in the directory D:\apps\jbin\com\jeffersonwells\util.
I have a manifest file that looks like the following.
     Manifest-Version: 1.0
     Main-Class: HelloWorld
     Class-Path: "d:\apps\jbin\"
I have created a jar with the manifest file and the HelloWorld class
When I run the jar, I get the following
     Exception in thread "main" java.lang.NoClassDefFoundError: com/jeffersonwells/util/JWIException
So, I believe the classpath is not being set correctly.
Then the second part would be to get the HelloWorld app to access the JWIException in another jar file instead of in the directory structure. I assume if the first scenario gets working, this will be fixed as well.
I would greatly appreciate any assistance you can provide.
Thanks,
Tom Krueger

I thank you all very much. The problem I was having was with not having relative paths in my Class-Path.
Having the relative paths will work for the most part, however, sometimes we may want to move the executable jar to a different location. Does anyone have a great solution taking the following into consideration.
Previous posts have said you can reference classpaths through http or ftp. Great, however if you set this to your http://domain/whatever I'm assuming this will prohibit you from moving the application from dev to test to production without modifying the url.
Thanks for any thoughts!!
P.S.
I'm also in a battle here whether to jar libraries or not. jaring allows you to easily move them from server to server and more importantly for me determine versions of compatible files. However, the argument against jaring is speed of development, why jar if I can pull up a java file compile it and copy it to the server. Why waste time in the whole jaring process.
Thanks again!!!
