Output to textfiles in a jar file.

To get what was in the text file i set it up liek this.
BufferedReader d = new BufferedReader(new InputStreamReader(getClass().getResourceAsStream("Settings.txt")));
then
String str= d.readLine(); and so on.
How would i output to that file in my jar?
Thanks

sorry i should be more specific.
That file already exists in my jar.
i got it, did somethign with the values in it now i want to get an outputstream to write something back out.

NAME
jar - Java archive tool
SYNOPSIS
jar [ -C ] [ c ] [ f ] [ i ] [ M ] [ m ] [ O ] [ t ] [ u ]
[ v ]
[ x file ] [ manifest-file ] destination input-file
[ input-files ]
DESCRIPTION
The jar tool is a Java application that combines multiple
files into a single JAR archive file. It is also a gen-
eral-purpose archiving and compression tool, based on ZIP
and the ZLIB compression format. However, jar was
designed mainly to facilitate the packaging of Java
applets or applications into a single archive. When the
components of an applet or application (.class files,
images and sounds) are combined into a single archive,
they can be downloaded by a Java agent (like a browser) in
a single HTTP transaction, rather than require a new con-
nection for each piece. This dramatically improves down-
load time. The jar tool also compresses files, which fur-
ther improves download time. In addition, it allows indi-
vidual entries in a file to be signed by the applet author
so that their origins can be authenticated. The syntax
for the jar tool is almost identical to the syntax for the
tar(1) command. A jar archive can be used as a class path
entry, whether or not it is compressed.
The three types of input files for the jar tool are:
o Manifest file (optional)
o Destination jar file
o Files to be archived
Typical usage is:
example% jar cf myjarfile *.class
In this example, all the class files in the current direc-
tory are placed in the file named myjarfile. A manifest
file is automatically generated by the jar tool and is
always the first entry in the jar file. By default, it is
named META-INF/MANIFEST.MF. The manifest file is the
place where any meta-information about the archive is
stored. Refer to the Manifest Format in the SEE ALSO sec-
tion for details about how meta-information is stored in
the manifest file.
To use a pre-existing manifest file to create a new jar
archive, specify the old manifest file with the m option:
example% jar cmf myManifestFile myJarFile *.class
When you specify cfm instead of cmf (that is, you invert
the order of the m and f options), you need to specify the
name of the jar archive first, followed by the name of the
manifest file:
example% jar cfm myJarFile myManifestFile *.class
The manifest uses RFC822 ASCII format, so it is easy to
view and process manifest-file contents.
OPTIONS
The following options are supported:
-C Changes directories during execution of the jar com-
mand. For example:
example% jar uf foo.jar -C classes *
c Creates a new or empty archive on the standard out-
put.
f The second argument specifies a jar file to process.
In the case of creation, this refers to the name of
the jar file to be created (instead of on stdout).
For table or xtract, the second argument identifies
the jar file to be listed or extracted.
i Generates index information for the specified jar
file and its dependent jar files. For example,
example% jar i foo.jar
would generate an INDEX.LIST file in foo.jar which con-
tains location information for each package in foo.jar and
all the jar files specified in foo.jar's Class-Path
attribute.
M Does not create a manifest file for the entries.
m Includes manifest information from specified pre-
existing manifest file. Example use:
example% jar cmf myManifestFile myJarFile *.class
You can add special-purpose name-value attribute
headers to the manifest file that are not contained
in the default manifest. Examples of such headers
are those for vendor information, version informa-
tion, package sealing, and headers to make JAR-bun-
dled applications executable. See the JAR Files
trail in the Java Tutorial and the JRE Notes for
Developers web page for examples of using the m
option.
O Stores only, without using ZIP compression.
t Lists the table of contents from standard output.
u Updates an existing JAR file by adding files or
changing the manifest. For example:
example% jar uf foo.jar foo.class
adds the file foo.class to the existing JAR file
foo.jar, and
example% jar umf foo.jar
updates foo.jar's manifest with the information in
manifest.
v Generates verbose output on stderr.
x file
Extracts all files, or just the named files, from
standard input. If file is omitted, then all files
are extracted; otherwise, only the specified file or
files are extracted.
If any of the files is a directory, then that direc-
tory is processed recursively.
EXAMPLES
To add all of the files in a particular directory to an
archive:
example% ls
0.au 3.au 6.au 9.au at_work.gif
1.au 4.au 7.au Animator.class monkey.jpg
e.au 5.au 8.au Wave.class spacemusic.au
example% jar cvf bundle.jar *
adding: 0.au
adding: 1.au
adding: 2.au
adding: 3.au
adding: 4.au
adding: 5.au
adding: 6.au
adding: 7.au
adding: 8.au
adding: 9.au
adding: Animator.class
adding: Wave.class
adding: at_work.gif
adding: monkey.jpg
adding: spacemusic.au
example%
If you already have subdirectories for images, audio
files, and classes that already exist in an HTML direc-
tory, use jar to archive each directory to a single jar
file:
example% ls
audio classes images
example% jar cvf bundle.jar audio classes images
adding: audio/1.au
adding: audio/2.au
adding: audio/3.au
adding: audio/spacemusic.au
adding: classes/Animator.class
adding: classes/Wave.class
adding: images/monkey.jpg
adding: images/at_work.gif
example% ls -l
total 142
drwxr-xr-x 2 brown green 512 Aug 1 22:33 audio
-rw-r--r-- 1 brown green 68677 Aug 1 22:36 bundle.jar
drwxr-xr-x 2 brown green 512 Aug 1 22:26 classes
drwxr-xr-x 2 brown green 512 Aug 1 22:25 images
example%
To see the entry names in the jar file using the jar tool
and the t option:
example% ls
audio bundle.jar classes images
example% jar tf bundle.jar
META-INF/MANIFEST.MF
audio/1.au
audio/2.au
audio/3.au
audio/spacemusic.au
classes/Animator.class
classes/Wave.class
images/monkey.jpg
images/at_work.gif
example%
To display more information about the files in the
archive, such as their size and last modified date, use
the v option:
example% jar tvf bundle.jar
145 Thu Aug 01 22:27:00 PDT 1996 META-INF/MANIFEST.MF
946 Thu Aug 01 22:24:22 PDT 1996 audio/1.au
1039 Thu Aug 01 22:24:22 PDT 1996 audio/2.au

527 Thu Aug 01 22:25:20 PDT 1996 images/at_work.gif
example%
If you bundled a stock trade application (applet) into the
following jar files,
main.jar buy.jar sell.jar other.jar
and you specified the Class-Path attribute in main.jar's
manifest as
Class-Path: buy.jar sell.jar other.jar
then you can use the i option to speed up your applica-
tion's class loading time:
example$ jar i main.jar
An INDEX.LIST file is inserted in the META-INF directory
which will enable the application class loader to download
the right jar files when it is searching for classes or
resources.

JAR file tip for winXP users

AAAAGH!
I've just discovered why my JAR file is SO big. Stupid winXP generates a hidden file called Thumbs.db in directories containing images if you browse them in the file explorer. If you add this directory to your JAR file it will include this file. This added 3MB to my JAR - removing it the JAR is under 2MB!
Tip - check the output when you create a jar file!

Yeah, this is truly irritating. Thumbs.db is a thumbnail cache and it's the price you pay to have the Fisher Price GUI Windoze XP is so well known for. You may notice if you chage these images all the time that the cache images don't match the actual images.
The best solution? Stop the damn thing altogether. To stop it do this:
Go to run and start regedit.exe then go to the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
Double-click DisableThumbnailCache value and change the value to 1 and press ok and close the registry editor then restart ur machine.

Decompiling jar file and then run

Dear Members,
I have a jar file and I have decompiled that jar file and converted into class file,
now I want to run/edit using source code ,I am unable to run source code with out put whatever coming in jar file running,
I am trying with class in which
public static void main(String[] args)
function defined,
I am using Jcreater1.5 and from command prompt also running but unable to run and edit the programm,
how to run these class file in complete project that output will come as running jar file
regards
SACHIN

It sounds like you have unpacked the jar.
To edit the source you need to decompile the classes to .java files.

Code ran fine in Eclipse, no output as a Jar file..help!

I have been working on a piece of code that reads an excel spreadsheet, and writes xml files based on that. (I'm to cheap to buy the numerous software out there)
The code ran beautifully in Eclipse, and all the right dialog windows and console outputs were present, as well as the final product, about 250 XML files.
I exported the src to a sealed jar file and ran it.
I get the first few dialogs that ask info of me, but as soon as it starts the process I get nothing!...
no exceptions, no errors, no xml...does anyone know what i did wrong?
Thanks so much for the help.

we can't help you if we don't know the real probelm you've got.
use an error logger like log4j http://logging.apache.org/log4j/docs/index.html and report the exception messages.

Adogjf Unable to generate jar files under JAVA_TOP error while patching

Hi,
I'm upgrading my version of Java from 1.3.1_19 to 1.5.0_17. I downloaded the jdk-1_5_0_17-linux-i586.bin file and unpackaged it to /u0/<SID>/<SID>db/10.2.0. It unpackaged it to a new directory jdk1.5.0_17 (/u0/<SID>/<SID>db/10.2.0/jdk1.5.0_17), whereas the old version is in a directory jdk (/u0/<SID>/<SID>db/10.2.0/jdk).
Having done that I had to run an interoperability patch (4372996). Upon running this patch I received an error at the end:
adogjf() Unable to generate jar files under JAVA_TOP
There were no other errors.
I think the problem has to do with where my new java version is located but I'm not sure. I'm thinking that it's still looking under the old JAVA_TOP (/u0/<SID>/<SID>db/10.2.0/jdk) when I want it to look under the new JAVA_TOP (/u0/<SID>/<SID>db/10.2.0/jdk1.5.0_17). So, should I move the contents from the new directory (jdk1.5.0_17) to the old directory (jdk) or is there a way to 'point' it to the new JAVA_TOP.
Please let me know if I'm totally off base and there's another solution. We're currently on EBS 11.5.10.2, DB 10.2.0.4 and RHEL 4 Update 5.
Thanks,
Lia.

Here you go. Hope this helps you to help me :-). Thanks.

My JAR file is not working properly!!!

Hi everyone,
I made an application that has a GUI (window). I converted it into a JAR file so I can send it to a friend by email. Then she can run it to generate the output. First, the user has to select a destination to save the .txt file (using JFileChooser). Then enters the inputs (using JTextFields). Clicks "Run" button (Results will be calculated and copied to the file). A Message will appear indicating that the results are copied. The problem is that when I run the application in the IDE (Eclipse) it works fine. But when I convert it into JAR, The moment I click the "Run" button, suddenly the window closes. Please HELP???
Thank you

Sorry guys, but i would like to make things clearer, As I mentioned earlier, What i'm doing is the following: 1) Using the Jfilechooser, save the results into a filename.txt file _[main class in the manifest file (class for the GUI) ]._ 2) Click "run" to write the data to the created file in step 1 [_another class is used to write to file_]. I have a feeling that the problem is related to the manifest main class. What do you think guys?I think your description of the problem is very bad. And I think your idea of making wild guesses is a bad way of diagnosing problems.
First of all. A JFileChooser does not save anything. It just allows the user to select a file to be saved to. So if you thought that the first step was writing anything or creating any file, you're probably wrong. But examining the code would help you understand.
Second, if you're having problems because one class chooses the file name and a second class writes data to it, then you're probably running into the basic beginner problem we see around here all the time of how to communicate data between objects. Again, examining the code might help.
Third, you need to understand what is writing that error message. Examining the code would help there too.
So: stop guessing. Look at the code.I'm still New To Java that's why i find difficulty in problems diagnosis. Regarding the JAR problem, as you mentioned, I used JFileChooser to select a file and (copying data) is the other part. So I will look at the code again.

OC4J: Class not found for class in jar file placed in \j2ee\home\applib\

I have an ADF application which uses external libraries (jars), which works fine when running the application from within JDeveloper (TP4).
However if I deploy the application to the embedded OC4J server it won't find any classes imported in those external libraries at runtime (deploy does work). E.g. one library class imports oracle.jbo.server.DBTransaction. If a method of this class is called I get the following exception:
Unexpected exception caught: java.lang.NoClassDefFoundError, msg=oracle/classloader/util/AnnotatedNoClassDefFoundError
oracle/classloader/util/AnnotatedNoClassDefFoundErrorThe same exception, when using a german locale, explicitely states that it cannot find oracle.jbo.server.DBTransaction.
The jar files are placed in the \j2ee\home\applib\ directory and a <library> element to this path is present in application.xml.
Any further hints what could be wrong?

Hi Edwin,
tried your suggestions but without success.
when I add this library to server.xml then following error occures when starting OC4J

Import JAR files (integrating JasperReports)

Dear all,
I'm using JDeveloper 11.1.1.3.0 on Windows 7 32bit.
I search this forum and I google a lot, but I couldn't find any workable solution.
I downloaded the newest version of JasperReport and iReport from the official website. I've done some tutorials from this site and everything seems to work fine.
Now I want to integrate JDev with JasperReports. I create new Fusion Web Application ADF, I get the properties of Model project, Libraries and Classpath tab, add Library and click New... I set the Library name as JasperReports, location as Project, check Deploy ad Default. I add to Class path every JAR files in E:\JasperReports\jasperreports-3.7.6\lib and to Source path the whole directory E:\JasperReports\jasperreports-3.7.6\src. I get sure that the Export is checked and I save all the changes.
I create a new Java Class JasperTest and I use this sample code:
import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.engine.export.*;
import java.util.*;
public class JasperTest {
    public static void main(String[] args) {
        String fileName = "test.jasper";
        String outFileName = "test.pdf";
        HashMap hm = new HashMap();
        try {
            // Fill the report using an empty data source
            JasperPrint print = JasperFillManager.fillReport(fileName, hm, new JREmptyDataSource());
            // Create a PDF exporter
            JRExporter exporter = new JRPdfExporter();
            // Configure the exporter (set output file name and print object)
            exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileName);
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
            // Export the PDF file

}I cant compile this, it gives me Error(1,1): package net.sf.jasperreports.engine does not exist etc..
I cant import any class from JasperReports. Did I something wrong with importing the JAR files to my project ? Maybe I should set some system environment variable ? What else I can do ?
Any help will be appraciated.
Regards,
Wojtek.

Hi,
I am also facing the same problem, I have few Jasper Reports which are closely integrated with my APEX applications, but for this i am using another application ( Jasper reports) which deployed in tomcat. This application hardly have 20 lines of java code, so i thought of embedding same in PL/SQL itself, But i am facing problem while importing JAR files i.e.
1. Where to put these JAR files so that i can import them in my PL/SQL.
2. I also tried using JAVALOAD function, but that also not worked for me.
Please give me some solution how to go about it??

How to create package and import from jar file?

Hi all,
I am writing a software and I am not sure how to create a package for the classes.
Say I have two classes in the same directory as follows:
testA.java
==========
package AB;
public class testA
public static void main(String[] args){
     testB myB = new testB();
     System.out.println("A test");
testB.java
===========
package AB;
public class testB
public testB(){
     System.out.println("B constructor");
both file compile without the package heading;
both file compile using: javac -classpath .\ *.java
Question 1:
I cannot run testA by: java -classpath .\ testA
I think it is a syntax error. What is the correct one?
If I run testA by: java testA
The only output I get is: A test
But I am expecting: B constructor /n A test
What went wrong?
Question 2:
I need to use APIs of another software. I have downloaded a .jar file (xxx.jar) with all the classes in it. And I have put "import xxx.*;" in my source file. But the compiler complains about the importing. What is the right way to copmile it?
I have read a couple of tutorials but they don't answer my question.
(I am using windows2000 and don't have the classpath variable.)
Hope some one can help.
Thanks a lot

Try moving testA out of the package and importing 'AB.*;'
If you have:
./testA.class
./AB/testb.class
Then to execute testA from ./ type: java -cp . testA

Error in deploying .jar file from JDeveloper 10.1.3.5

Hello,
I want to deploy .jar file in a machine, instead of having to install JDeveloper to run the application (it contains: Web Services and Data Base).
I have followed the following steps in JDeveloper to create the .jar file:
1) Right click over the project: New... --> General (All Technologies option selected) --> Deployment Profiles --> JAR File
2) I have selected "Include Manifest File" option specifying the application's main class
3) In JAR Deployment Profile Properties window: File Groups --> Project Output --> Contributors are selected: "Project Output Directory" and "Project Dependencies"
4) With the previous steps, JDeveloper generates a .deploy file. It is created in Resources folder. From this folder, I have selected the .deploy file and right click and I have selected "Deploy to JAR file"
The .jar is created succesfully. In this point, I try to execute with the command:
java -jar NAME_OF_THE_DIRECTORY_WHERE_THE FILEIS_DEPLOYED\NameFile.jar
and I have the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/rpc/ServiceFactory
at project.proxy.AccountClient.<init><AccountClient.java>
at project.proxy.AccountClient.main<init><AccountClient.java>
The Manifest File content is:
Manifest-Version: 1.0
Created-By: Oracle JDeveloper 10.1.3.5.0
Main-Class: project.proxy.AccountClient
I have tested with differents variables to create the .jar file, but always the error is the same. And I haven't found information to solve it. For this reason, I appreciate any help.
Thank you and regards.

If you are just building a client that access a Web service you need a JAR and not a WAR.
Ok!
One thing to try is look at the command line that JDeveloper uses to run your client (it's in the log window) - specifically look at the classpath used.
Then try and run the same thing from a command line and see if it works.
Nowadays, the application is running with a .BAT file, it contains the statement released from the JDeveloper console, and it is working perfectlly.
I try to do the same from a command line, and it works too.
Assuming it is - you can either use that, or you'll need to make sure that your JAR includes all the mentioned jars that were in the class path - this is done through the library type file group.
To create the .JAR file I have choosen the following options (JAR Deployment Profile Properties):
1) Include Manifest File --> I have selected the class that contains the main class (from the Browse option)
2) I left the default File Groups (Project Output) --> it has: Project Output Directory + Project Dependencies
3) As you said me, I have created a new File Group (type: Libraries) --> and here, I have selected all the possible Contributors. These match those specified in the project (Oracle XML Parser v2, J2EE, JAX-RPC Client, Commons Logging 1.0.3, Ojdbc14.jar).
4) Deployment to JAR File successfully.
The resulting MANIFEST.MF is:
Manifest-Version: 1.0
Created-By: Oracle JDeveloper 10.1.3.5.0
Main-Class: project.proxy.Execution
It hasn't definied "Class-Path", althought to especified a new File Group with the libraries... Is it an error?
If I extract the .JAR file, I see all libraries, and I have two folders: one with .class files of my project and other one is META-INF with MANIFEST.MF file.
5) From command line I executed:
C:\jdevstudio10135\jdk\bin > java -jar C:\jdevstudio10135\jdev\mywork\project\project\deploy\NameFile.jar
And the result is an error:
Exception in thread "main": java.lang.NoClassDefFoundError: javax/xml/rpc/ServiceFactory
I think the error is because it can not find the library ServiceFactory, but it is especified inside JAX-RPC Client library. What is wrong?
*6)* I have tried too to insert in "JAR Deployment Profile Properties" (in JAR options) an additional Manifest File to merge into MANIFEST.MF, to include "Class-Path" with all libraries's project (the same JAR from the statement released from the JDeveloper console), but I think that it is a limit, because if I insert all libraries the "Class-Path" doesn't inserted in MANIFEST.MF. The maxim is:
Class-Path: C:\jdevstudio10135\jdev\mywork\project\project\classes C:\jdevstudio10135\lib\xmlparserv2.jar C:\jdevstudio10135\lib\xml.jar C:\jdevstudio10135\j2ee\home\lib\activation.jar C:\jdevstudio10135\j2ee\home\lib\ejb.jar C:\jdevstudio10135\j2ee\home\lib\jms.jar C:\jdevstudio10135\j2ee\home\lib\jta.jar C:\jdevstudio10135\j2ee\home\lib\mail.jar C:\jdevstudio10135\j2ee\home\lib\servlet.jar C:\jdevstudio10135\webservices\lib\jaxrpc-api.jar
The following libraries afther the previous one aren't allowed to include because I think that is exceeding the maximum size.
I have tested to create various MANIFEST.MF with different PATHs libraries, but it isn't work to include in the MANIFEST.MF file all libraries...
(C:\jdevstudio10135\webservices\lib\wsclient.jar
C:\jdevstudio10135\webservices\lib\wsserver.jar
C:\jdevstudio10135\webservices\lib\wssecurity.jar

C:\oracle\product\10.2.0\client_1\jdbc\lib\ojdbc14dms.jar
C:\oracle\product\10.2.0\client_1\jdbc\lib\ojdbc14dms_g.jar)
With this .MF file (or including only "C:\jdevstudio10135\jdev\mywork\project\project\classes") I have solved the other problem (not found the libraries), but it still not working, the error is a little different:
Exception in thread "main": java.lang.NoClassDefFoundError: project/proxy/Execution
The path where the main class is: C:\jdevstudio10135\jdev\mywork\project\project\classes\project\proxy\Execution.class
I have tried to insert directlly the following paths in "Main Class" option of "Include Manifest File":
C:\jdevstudio10135\jdev\mywork\project\project\classes\project\proxy\Execution
C:\\jdevstudio10135\\jdev\\mywork\\project\\project\\classes\\project\\proxy\\Execution
And with these values, the error is the same: Exception in thread "main": java.lang.NoClassDefFoundError
I am not sure if the error is a bug of JDeveloper 10.1.3.5 or it is something that I don't correctly. Any idea?
Thank you again and regards.

Include an in-memory jar file for JSR-199 compilation

I want to compile a source file in memory, which requires a jar file that is also represented in memory. I used the JavaSourceFromString class recommended in the documentation for the class JavaCompiler and in a demo I found online that shows how to compile sources represented as String in memory. To represent the jar file, I used a similar trick to JavaSourceFromString:
public class JarJavaFileObjectFromByteArray extends SimpleJavaFileObject {
   * The contents of this jar file.
private final byte[] contents;
   * Constructs a new JarJavaFileObjectFromByteArray given the name and binary
   * contents of a jar file.
   * @param name the name of this jar file
   * @param contents the contents of this jar file
public JarJavaFileObjectFromByteArray(String name, byte[] contents) {
    super(newURI(name), Kind.OTHER);
    this.contents = contents;
... // code not shown ensures that the URI returned from newURI is of the form,
      // for instance, bytes:///MathConstants.jar, if the name of the jar file is MathConstants.jar
@Override
public InputStream openInputStream() throws IOException {
    return new ByteArrayInputStream(contents);
}However, I do not know how to alert the compiler that this jar file should be on the classpath. I tried this:
List<String> options = Arrays.asList(" -classpath bytes:///MathConstants.jar ");
CompilationTask task = compiler.getTask(null, fileManager, null, options, null, compilationUnits);but I get the following error when calling getTask:
java.lang.IllegalArgumentException: invalid flag: -classpath bytes:///MathConstants.jarI assume there is some way to tell the compiler, "look at the MathConstants.jar file that I am storing in memory when searching the classpath", but I do not know how to do this. I assumed that the options parameter for getTask represents command-line flags that would be passed to the compiler if this were happening on the command line (such as "-cp .", which also does not work), but perhaps this assumption is wrong.

Hi Bruce,
I have a question regarding loading a jar file by the compiler to dynamically compile with a source file. I hope you can probably offer me an idea on what has been missing or wrong with the source codes I have written for my application.
I am using Eclipse compiler to dynamically compile a class. In the class, I want it to make a reference to a jar file for compilation dynamically.
Here is the source of a test class I wrote:
import javax.servlet.http.HttpServlet;
class MyServlet extends HttpServlet {
}The import statement refers to the class javax.servlet.http.HttpServlet from the jar file C:\\Program Files\\Apache Software Foundation\\Tomcat 6.0\\lib\\servlet-api.jar placed in the file system.
In the method called compileClass (shown below), I used the path of the jar file to add to the option -classpath as you suggested.
     private static CompileClassResult compileClass(Writer out, String className, String classSource) {
          try {
               JavaCompiler javac = new EclipseCompiler();
               StandardJavaFileManager sjfm = javac.getStandardFileManager(null, null, null);
               SpecialClassLoader scl = new SpecialClassLoader();
               SpecialJavaFileManager fileManager = new SpecialJavaFileManager(sjfm, scl);
               List<String> options = new ArrayList<String>();
               options.addAll(Arrays.asList("-classpath", "C:\\Program Files\\Apache Software Foundation\\Tomcat 6.0\\lib\\servlet-api.jar"));
               List<MemorySource> compilationUnits = Arrays.asList(new MemorySource(className, classSource));
               DiagnosticListener<JavaFileObject> diagnosticListener = null;
               Iterable<String> classes = null;
               if (out == null) {
                    out = new PrintWriter(System.err);
               JavaCompiler.CompilationTask compile = javac.getTask(out, fileManager, diagnosticListener, options, classes, compilationUnits);
               boolean res = compile.call();
               if (res) {
                    //Need to modify the api to return an array of two elements - one classes and other bytecodes for all classes in the same class file.
                    return CompileClassResult.newInstance(scl.findClasses(), scl.findByteCodes());
          } catch (Exception e) {
               e.printStackTrace();
          return null;
     }I also extended the class ForwardingJavaFileManager as you suggested and have it delegated to the StandardJavaFileManager sent to the compiler mentioned in the method compileClass above. The extended class (called SpecialJavaFileManager) is as follows:
public class SpecialJavaFileManager extends ForwardingJavaFileManager<StandardJavaFileManager> {
     private SpecialClassLoader xcl;
     public SpecialJavaFileManager(StandardJavaFileManager sjfm, SpecialClassLoader xcl) {
          super(sjfm);
          System.out.println("SpecialJavaFileManager");
          this.xcl = xcl;
     public JavaFileObject getJavaFileForOutput(Location location, String name, JavaFileObject.Kind kind, FileObject sibling) throws IOException {
          System.out.println("getJavaFileForOutput");
          MemoryByteCode mbc = new MemoryByteCode(name);
          xcl.addClass(name, mbc);
          return mbc;
     public Iterable<JavaFileObject> list(JavaFileManager.Location loc, String pkg, Set kinds, boolean recurse) throws IOException {
          System.out.println("list ");
        List<JavaFileObject> result = new ArrayList<JavaFileObject>();
        for (JavaFileObject f : super.list(loc, pkg, kinds, recurse)) {
             System.out.println(f);
            result.add(f);
          return result;
}I run the application and the result shows that it didn't load the jar file into the memory as expected. From the output (below) I got, it doesn't seem to invoke the method list(...) in the class SpecialJavaFileManager.
SpecialJavaFileManager
1. ERROR in \MyServlet.java (at line 1)
     import javax.servlet.http.*;
            ^^^^^^^^^^^^^
The import javax.servlet cannot be resolved

     class MyServlet extends HttpServlet {

Thanks.

How to include externel library in JAR file?

Hi all =)
I have a program that uses an external library (in a JAR file) I would like to compile my program as a JAR and have it include the external library that it needs to run, so that the external library would not need to be on the computer running my program. How can I do this?
Thanks =)

Ok I was able to make my JAR and launch my application correctly. However whenever I click a button that has a method using my external library I get the following error:
C:\Documents and Settings\Koneko>java -jar D:\Mangment.jar
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/apache/poi/poifs/filesystem/POIFSFileSystem at managment_system.ManagmentGUI.getNextStat(ManagmentGUI.java:569) at managment_system.ManagmentGUI$1.actionPerformed(ManagmentGUI.java:195)
I do not get this error when I run and use my program from within the IDE.
The JAR that has my external library (and has the class for POIFileSystem) is also on my D drive and i referenced it correctly (I think) In my classpath:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
     <classpathentry kind="src" path=""/>
     <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
     <classpathentry kind="lib" path="D:/poi.jar"/>
     <classpathentry kind="output" path=""/>
</classpath>I would really like to get this working and I'm very confused XP
