Include rt.jar class files in my own jar file to run 1.2+ applets on MS JVM

My problem is this. I'm writing an applet (which includes 1.2 classes) for my organization (over 2000 NT workstations) in which no one has administrative privelages to install Sun's JRE 1.2 or greater. The target browser is IE 5. Our NT admins are having problems pushing the JRE out so my only two options are to rewrite everything as 1.1 or somehow include the missing class files from rt.jar.
I really do not want to rewrite it all!
I was able to extract the missing class files (i.e. /java/util/HashMap.class) but I cannot figure out how to get the IE JVM to use them. Things I have tried:
1. jarred up all my class files along with the missing classes from rt.jar.

2. Tried to just place missing *.class files in same directory as my class files

If anyone has done this before or knows how to do it, please help me out.
Thanks!

When the collection classes first came out, I think they were available in a separate jar (although the package name may be slightly different). If it's just collection classes, that might be worthwhile looking at.
The MS JVM may be spewing because the class format is too new; you may try with rt.jar classes from an older JVM (such as JDK 1.2), or try to recompile them from source using -target 1.1.

Applets reading files in their own jar file

I know there is no way to get my applet to read a file on the hard disk. But
could I read one that I include in with the .jar file that I create for my applet?
What about using a Resource type of file? Is this possible?
Thanks

Here's a little code stub I used to read a properties file from rt.jar    Properties p = new Properties();
    InputStream is = ClassLoader.getSystemClassLoader().getResourceAsStream
     ("java/awt/resources/awt.properties");
    if (is == null) System.out.println("NULL");
    else try { p.load(is); }

    p.list(System.out);You should be able to substitute your path & properties file

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:

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.

Including a jar file inside an executable jar file

Is it possible to include a jar file inside another (executable) jar file such that the included file is part of the class path for the outer file? If so, how do you specify this in the classpath in the manifest?

Russ_Bjork wrote:

What do you see as the advantage of doing that?
Is your app. a rich client (e.g. Swing, AWT, SWT..)?
Can you distribute the app. from a server or the internet?

How to run a jar file which needs another jar to be in the class path

Hi,
I need to execute a jar, which needs another jar to be in the classpath.
If I run like
java -classpath <jar1 name> -jar <main jar>
It is giving classnotfoundexception, where as the class is available in the <jar1 name>.
so, currently I am doing like this
In the manifest file i have given like
Main-Class: <class name>
Class-Path: <jar name> <jar name2>
then it is running fine. But, if I want to change the jar location again I need to changed the manifest file.
Is there any way to do this? Pls help me.

How about
java -cp jar1.jar;jar2.jar com.acme.MainClass
You won't need to worry about the manifest file after that and you can make a bat files (or .sh file in *nix) for it.

Classes+resources in JAR: have to add each single Jar file to CLASSPATH?

Hello,
For my application, I plan to easily embed plugins that can be added by the user by copying it into a subfolder "plugins".
Now, I start my app from a shellscript and in order to load resources from within some of these Jars (e.g. using Class.getResourceAsStream() ), it only works if I explicitly add the specific Jar filename to the classpath from the shellscript.
I read in a German Java book, that also just using folder names is enough, but it does not work for me:
Works:
$JAVA_HOME/bin/java -Djava.library.path="./lib" -classpath "./lib:./plugins/test.jar" test.AppFails:
$JAVA_HOME/bin/java -Djava.library.path="./lib" -classpath "./lib:./plugins/" test.AppIs it really required to add Jars explicitly, so that e.g. my shellscript has to make a Jar listing of that folder in order to pass them as classpath files?
Thanks and regards,
Timo

No, you don't have to do it that way. What you need
to do is to have your progam create a URLClassLoader
pointing to all the jars in the plugin directory.
Then request your plugin classes from that, rather
than Class.forName();
You need to create an array of file URLs for the
jars, use File.listFiles() and then File.toURL() on
each ..jar you find.
p.s. If you do it this way make sure your plugin
classes are not on the classpath.
Hmm. Cool. I had no idea. Thanks for correcting me.

Include a JSP file located in a JAR

how is it possible to include a jsp file which is located in a jar? perhaps someone has already a solution for this hoping
what I already have found out is that jasper parser supports loading JSP files out of JARs, indeed. but when using a <%@import file="foo.jsp"%> directive, this special method is not called. is there some workaround? should I set some special property?
thx

Did you ever figure this one out?

Read from own jar file

Using netBeans IDE 4.1 I wrote a stand-lone application contained in a single jar file. It transforms xml files into drawings. I'd like to distribute the application with some sample xml-files in that one jar-file. But how can I make the application read these embedded files?
I looked at the SplitPaneDemo that uses a list of images to display.
http://java.sun.com/docs/books/tutorialJWS/uiswing/components/example-1dot4/SplitPaneDemo.jnlp
works.
I also downloaded
http://java.sun.com/docs/books/tutorialNB/download/tut-examples.zip
extracted uiswing/components/example-swing
created a new project from existing sources
made SplitPaneDemo the main class
and run it after a clean build.
The images are in the jar-file, but no images appear.
Is the problem in the second attempt a missing classpath? In that case: how can I prevent my a-technical users having to set a classpath, or how can I find out and use the absulute path to the jar-file?

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.

Web application in EAR not finding class in APP=INF/lib jar file

Hi,
I have read some posts regarding this but am still not able to figure out anything.
I have a war file in my EAR along with some EJB jars. I have the common jars in the APP-INF/lib. The EJBs can find the classes in the common jars easily. But the Web app gives me a NoClassDefFoundError when trying to load a class from a common jar.
Here is the structure:
<pre>
EAR
|---WAR
|---WEB-INF
| |---lib
| |---a.jar (A.class)
|---APP-INF
|---lib
|---b.jar (B.class)
</pre>
Class A is trying to load class B and I get the NoClassDefFoundError for class B
Thanks for any help,
Sameet

I found the problem. The web-app was finding the class in the APP-INf/lib. But the problem was being caused due to a reference to another class that was being loaded by the webapp classloader which was not visible to the class inside the common jar. The solution was to make sure both classes were being loaded by one class loader.
Thanks anyway

Can I synchronize all iBooks documents (including pdf files of my own) using iCloud?

It looks impossible to sync iBook files between devices using iCloud. It works for iBook files bought at iTunes, but not for pdf files of my own. It should work the same as for emails, note's, foto's and other stuff that is synchronized using iCloud. Any suggestions besides using other cloud storage?

How to enable full autocomplete description with own JAR ?

Hi there,
To put my problem simply: I've created a JAR file and wish to utilize it within another Java project. Therefor I've imported the JAR file in my project path (I've done this in Eclipse and IntelliJ) and in both IDEs the JAR file works just fine.
But... I wish to use the autocompletion (yes, I'm a bit lame) in both IDEs. Now, whenever I import and call a function of a standard class (like java.util.Vector i.e.), the autocomplete pops up when writing the call to that specific function (i.e. add(Object o)). The autocomplete shows:
- the parameter names & types;
- the return type.
Now that's what I like to see also when calling a function of a self written class included in my own JAR. The only thing the autocomplete shows is the parameter types, not their names.
How on earth do I enable my autocompletion to show also the names of the parameters ?
I thought the blame could be the IDEs, but it's rather unlikely when two different IDEs behave similar in this matter. And it's not a bug in JAR itself. Perhaps I'm missing a specific argument when I jar up *.class files (I even tried to jar up the *.java files along, but without any results). Or perhaps it is something totally not possible (but I doubt that).
So, who's got the answer to this matter? Thanks in advance!
Greetings,
Naifud

But I did import the class I'd like the
autocompletion on.With an "import" statement, or do you mean you added its JAR to the build path? I mean the former. That sometimes helps, and usually works for me.
An example of how the a.c. looks like with a standard
Java class/import:
public object get(int index, String objectName)
And this is how the a.c. looks like when used on my
own class:
public object get(int, String)Aaaaaah. That's what you mean. I thought you meant it doesn't work at all.
Well... may I safely assume that you neither included the Javadocs nor the source code in that JAR? How would the IDE know what you call your parameters like? The binary code doesn't tell.
I've posted this already in a forum for the Java
IDEs, but instead of providing a proper solution,
they turned the topic into a flaming war about that
Eclipse would be far superiour than IntelliJ and
otherwise. So I tried it over here, hoping for more
civilisation ;).Forget it.

How to include Managed bean class in build sciprt for taskflow (Jdev 11.4)

Hi,
I've developed a custom taskflow to be deployed in the webcenter spaces. The taskflow that I developed contains managed beans. I am using oracle provided build script with the sample application, to deploy custom taskflow. After the build, we don't see any .class files (managed bean files) in the generated war file. Once we deploy the taskflow into the space, it is failing may be because the managed bean class files are missing in the <taskflow>.war. Am i missing something? Should we specifically include the .class files in the build script?

How to import custom java jar/class into oracle to be used in java proc ?

Hi
I would like to know how to import custom java jar/class files into oracle to be used in java stored procedure.
I am developing a oracle pl/sql procedure to call java program. The java program will be created as procedure and will be published.
But, my question is that I do have a other external jar/class file that need to be imported into this java program.
example
raise_sal.java
import java.util.*;
import oracle.sql.*;
<<reference other java programs >>
import cmpmsgsvc.xxxx.* ;
import cmpmsgsvc.yyyy.* ;
import cmpmsgsvc.zzzz.* ;
how do I import the cmpmsgsvc jar/class file into oracle so that I don't have any
compilation errros on raise_sal.java program ??
what are the steps to import/compile and validate to do this?
thanks for your help in advance.
Thanks

Problem is that, I have 6 jar files that are needed to be included in the main java program. And, there are more than 50+ classes, propertiers in those 6 jar files.
It might be not good idea to have all those 50+ classes in the production database.
Is there anyway that I keep all those 6 jar files in unix box (our's is oracle erp installation with oracle being installed on unix box) and just refer them in the main java program. I mean database will be loaded with main java program and it should able to refer other 6 jar files from unix.
if we create a directory and keep all jar files in there and include that directory in classpath variable, does this works? or what is other method?
Please let me know.
Thanks

Gif file not found in JAR from Java Application

Hello Forumers,
Could some one please explain how to create a JAR file from where I can get a GIF file. I have tried a number of different ways but it allways fails. (I have tried to add the GIF files using the jar command and I have tried to add it using WinZip after the jar is created).
To isolate the problem I created this very simple program, the program works very well when the gif file resides on the directory from where I run the Application, but when I remove it from the directory it fails. I have tried to put the GIF file in the JAR in a number of different ways but it allways fails. (I have also tried with and without slash before the name of the GIF). I guess the problem is the way I create the JAR file
import java.io.*;
public class GifTest
{ public static void main(String args[])
{ InputStream in = GifTest.class.getResourceAsStream("/open.gif");
if (in==null)
System.out.println("Null returned");
else
System.out.println("OK");
Any Hints appreciated

Hi,
here is a small application using my own class GetImageIcon.
Normally I have this "help-class" in a utility-package to use it from all my projects without copying. For this example I copied the code in the test application. Feel free to use the code of the class like you want. For me it works fine.
Do the following:
1. Create a folder called /meta-inf under the folder where the class-files are. Use a text-editor and create a file saved as "manifest.mf".
manifest.mf tells the jar-file which is the main-class from where the application will start when double-clicked.
It only has to contain one line:
Main-Class: GifTest
2. Compile and create the jar file. I made a bat-file containing:
javac -verbose GifTest.java
%pause
REM Create Jar-File
jar cmf meta-inf/manifest.mf GifTest.jar *.class *.gif
REM Show Table of Content of the Jar-File
jar tf GifTest.jar
%pause
So you can see what's in the jar-file.
3. When you double-click on the jar-file the application is executed. So it is easier to use for the users. They don't have to type in anything on the command-line. You can deploy this jar-file to any client and run it. The only thing you have to do, is to install the JRE on the clients.
I develop with JDK 1.3.1 and JRE 1.3.1 is installed on the clients of the company I work for.
