Jar files paths

ok I know how to get the path from where the code is being executed with applets, but if im executing it as a jar file how do i get the path on where the code is?

you can make the jar files know where your main class codes are by specifying the Main-Class attribute in your manifest.mf file
Main-Class MainClass

How Can I get the Jar file path ?

I have an aplication in a Jar file. This application might be situated in any directory.
I would like to know programatically the path where it was installed.
Is there any way to know this simple thing in Java? I cannot believe that there is not a function like System.getProperty("user.dir") for this as System.getProperty("user.dir") will always return the directory from where the Java VM was lauched!
Thank you!

You can get the location with:
URL codeBase = getClass().getProtectionDomain().getCodeBase().getLocation();But as has been pointed out, it's probably better to specify the directory to store these files some other way, e.g. use a batch file or shell script to launch your program and make it the cuirrent directory, or put the directory in as a property or command argument.

How to know which class is being loaded from which jar file & path location

Hi,
I have some Java code using several jar files.
I want to remove those jar files which are not being used by the code.
So , I want the JVM to output which class is being loaded from which jar .
Using "java -verbose" option doesnt solve the problem because the required info is printed only for the classes/jars native to the J2SE package .
Can anyone provide a solution which does not require me to modify the code?
Thanks,
Danish

For debugging purposes you could use [DriverManager.getDrivers()|http://download.oracle.com/javase/6/docs/api/java/sql/DriverManager.html#getDrivers%28%29] to get an enumeration of all drivers
and then output their names.
Maybe, with the classloader malarkey you are doing
you need to use [DriverManager.registerDriver(Driver driver)|http://download.oracle.com/javase/6/docs/api/java/sql/DriverManager.html#registerDriver%28java.sql.Driver%29]

How to access classes in jar files

hi I have added a jar file to my project in eclipse.How to access the classes in that jar file?

cu is right.
classloader returns the URL of your resource. You can the jar using something like the following...
ClassLoader classloader = this.getClassLoader();
url = classloader.getResource("your_resouces...");
if(url == null)
System.out.println("cannot find resource ");
return null;
String jar = url.getFile();
jar = jar.substring(jar.indexOf("/")+1, jar.lastIndexOf("!")).replace('/', '\\');
obviously, this code snippet works on windows only. Now you have the jar file path. I use Jar file classes to access the jar file. (e.g. you can search for each class files)

Access jar file from in-memory classes...

I have some classes that I compile to memory and everything works fine until one class that must access some external jar files. I have been unable to access those jar files from disk after trying every suggestion using URLClassLoader. I even tried someone's example to hack the SystemClassLoader which properly adds the jar file paths, but still they can't be seen. The only way it works is if I put the files in the jdk/jre/lib/ext directory. Then everything works fine. There must be a way to load the jar files in memory as well as the class files so they can be accessible. Has anyone done anything like this? Is it possible? Even though the class files are in memory, why would the jar files not be seen even when they are added to the same URLClassLoader's URL's. Thanks.

Sorry that wasn't clear. What I mean is that the classes are compiled to byte code directly to memory and no physical .class file is created. Yes, I'm using my own ClassLoader that extends URLClassLoader and I'm setting the parent to ClassLoader.getSystemClassLoader(). I also should mention that I'm doing this inside a Netbeans module that is part of a Netbeans Platform application. I don't know why that should matter though, since I'm trying to do everything in memory without creating the physical files. Thanks.

Weblogic Server not picking the jar files in WEB-INF/lib folder

we are facing a strange problem where Weblogic App Server is not picking the jar files present inside the WEB-INF/lib folder if we update the jar file path in the classpath of the start script then the classes get loaded properly.
Is there any specific setting which I need to do in weblogic to pick these jars ?

Class loaders associated with a Web application can be configured to locate local classes first. To enable this we have to set the <prefer-web-inf-classes> to true in the deployment override weblogic.xml, for example
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>

Cannot make executable jar file for swt application

hi to all!!! i have started learning swt library and it seems nice to me, but i have one problem, i cannot run my application. The problem is that i cannot make executable jar for it.
i'm using ecilpse_3.1.2 and have pluggined the visual editor for swt! yesterday i found one topic where was described the process of making the swt executable jar, i followed the instructions in the topic, but didn't resolve my problem, so if anybody knows how to achieve this , please help!!!!!!
the instructions in the mentioned topic are :
1. Make sure the SWT jar file is included in the Eclipse project build path
a. Download the standalone SWT jar file from eclipse.org even if you already have the ones that come with Eclipse. It is called ?swt.jar? and you will package it with the executable JAR. Make sure it is the same version of SWT that you used to make your program.
b. In Eclipse, import swt.jar via Project Properties::Java Build Path::Libraries::Add External JARs. (Make sure to include the source .zip file). Also make sure to select the swt package in the ?Order and Export? tab.
c. At this point, you should be able to compile and run your SWT application in the Eclipse SDK.
2. Do a standard Eclipse jar file export
a. Right click on the main .java project file and select ?Export??.
b. Choose ?JAR File? from the list.
c. Select the relevant packages and .classpath and .project resource files
d. Make sure ?Export generated class files and resources? is selected and browse to the location where you want the JAR file to be created.
e. Specify ?Generate the manifest file? and don?t seal the JAR or any packages. Choose the class containing the main method as the ?Main class?.
3. Change the manifest file
a. Navigate to the JAR file you created and open it with WinZip.
b. Open the MANIFEST.MF file inside and copy the contents.
c. Create a new file called ?MANIFEST.MF? and paste in the contents of the old manifest file.
d. Add the line ?Class-Path: <swt jar file path>?. For simplicity, you can just keep a copy of the swt.jar file in the same folder as the executable jar, in which case, the line is ?Class-Path: swt.jar?. Make sure there is a carriage return after the last line in the manifest file, or that line will not be parsed.
4. Replace the manifest file
a. Make sure the manifest file and the executable jar are in the same folder.
b. Open the command prompt and navigate to the containing folder.
c. Enter the command ?jar umf MANIFEST.MF <executable jar name>? to update the manifest file with the class path information.
5. Package the JAR with SWT files
a. Put the updated executable JAR file, swt.jar, and the associate DLL in the same folder. The DLL can be pulled out of swt.jar and should have a name like ?swt-win32-####.dll? on Windows.
b. The JAR file should now successfully execute. On Windows, you can usually just double click the JAR file in explorer and it will open. If that does not work, the command ?java ?jar <executable jar name>? on the command line has the same effect.
but a few steps aren't exact for me , for example : first, which jar i have to include in build path : downloaded or from plugins folder, second
i have to incude source.zip too??? but it is only in downloaded zip file which includes both swt.jar and src.zip, and finally can anyone clarify next :
"5. Package the JAR with SWT files
a. Put the updated executable JAR file, swt.jar, and the associate DLL in the same folder. The DLL can be pulled out of swt.jar and should have a name like ?swt-win32-####.dll? on Windows."
what does this mean, put these in folder or make jar from them????

wolve634 wrote:
but a few steps aren't exact for me , for example : first, which jar i have to include in build path : downloaded or from plugins folder, secondTry it both ways. If neither works, then ask again. In a suitable forum, though. An Eclipse forum or an SWT forum or something related to where you got those instructions would make a lot more sense than asking here.
i have to incude source.zip too???No, of course you don't have to distribute the source code.

Java 5.0 does not recognize wrapped Class-Path in Manifest.MF of .jar file?

Java: build 1.5.0_05-b05
Ant: 1.6.2
I use Ant <jar> task to create a standalone application in a .jar file. I have a very long "Class-Path" in the Manifest.MF file. The long Class-Path is wrapped at every 70th character by the <jar> task. I cannot run "java -jar <the jar file>", because Java runtime cannot find classes.
I found the following Q&A from ANT's FAQ page,
Q: Whenever I use the Ant jar or manifest related tasks, long lines in my manifest are wrapped at 70 characters and the resulting jar does not work in my application server. Why does Ant do this?
A: Ant implements the Java Jar file specification. Please refer to the notes section where it discusses the maximum allowable length of a line and the concept of continuation characters.
If a jar file produced by Ant does not work in your appserver, and that failure is due to the wrapped manifest, then you need to consult your appserver provider, as it is a bug in their appserver. Far more likely, however, is a problem in your specification of your classpath. It is not Ant's wrapping of your classpath that is the problem.
Do not raise a bug about this issue until you have checked to ensure that the problem is not due to your classpath specification.
Any idea?

"will be searched ALSO."...
From: http://java.sun.com/docs/books/tutorial/ext/basics/load.html
Understanding Extension Class Loading
The extension framework makes use of the new class-loading mechanism in the JavaTM 1.2 platform. When the runtime environment needs to load a new class for an application, it looks for the class in the following locations, in order:
1. Bootstrap classes: the runtime classes in rt.jar and internationalization classes in i18n.jar.
2. Installed extensions: classes in JAR files in the lib/ext directory of the JRE.
3. The class path: classes, including classes in JAR files, on paths specified by the system property java.class.path. If a JAR file on the class path has a manifest with the Class-Path attribute, JAR files specified by the Class-Path attribute will be searched also.

How do I add a jar file into the build path of the compiler?

Hey,
I'm trying to import a jar file into the build path of the compilation process, but it does not find the packages or the classes that are in it.
I think I don't add it right...
          ArrayList<String> options=new ArrayList<String>();
          options.add("-d");
          options.add(targetDirectory);
          options.add("-classpath");
          for(String str:includeDirectory)
               options.add(str);
          if (!compiler.getTask(writer, fileManager, diagnostics, options, classes, compilationUnits).call());
                ....and I've tried this way:
     public void setTargetDirectory(String targetDirectory) {
          this.targetDirectory = "-d " + targetDirectory;
     private void compile(Iterable<? extends JavaFileObject> compilationUnits) throws Exception {
          ArrayList<String> options = new ArrayList<String>();
          options.add(targetDirectory);
          String classPath="-cp ";// tried this also with "-classpath"
          for (String str : includeDirectory)
               classPath+=str+":";
          options.add(classPath);
     if (!compiler.getTask(writer, fileManager, diagnostics, options, classes, compilationUnits).call())
          // throw new Exception("Compilation Error");
     }Thanks in advance,
Adam.

Thank you for your reply,
Q: Are there .class files in that directory in that jar file? (the compiler doesn't ( can't )) look for directories, it can just look for specific files , and scan to get a list of all files matching certain criteria. So if there are no class files, it will say the package doesn't exist, even if there is a directory, possibly containing other files.yes there are class files in the jar, the tree structure:
j2MeDataChunkGenerator_Plugin\(lots of class files)
META-INF\manifest.mf
and thats it.
, your code will only work on windows because other platforms use a different path separator. You should use java.io.File.pathSeparator not explicit ';" when building your classpath. (this is unrelated to your problem, but you should correct it)will do, thanks.
Q: Is that error in your post formatted by your own diagnostics? (we could possibly help you better if we didn't have to guess!!)I would not post my own error code, this text is generated by the compiler diagnostic.
{code}
     System.err.println(" Error details: " + diagnostic.getMessage(null));
{code}
Q: Is line 3 of ImageCroper_Editor.java (sic) an import statement? (we could possibly help you better if we didn't have to guess!!)it is an import error... didn't the error message stated that it is an import problem? wired, I'm sure before it did. anyway it is an import error.
Also you don't show us what the variable includeDirectory is in terms of type, and contents, that might be helpful. (we could possibly help you better if we didn't have to guess!!)It has only one String object: "D:\%Important Documents\WorkSpaces\PacMan\ApplicationManager\Plug-in\Data Chunk Designer.jar"
the last file on the classpath list.
Q: Have you proven this? that i did post, in this long line of text.
Q: Is the compiler finding other classes (in other packages) in that same jar file?No. all the class files are in the jar, they all have entries that start with "j2MeDataChunkGenerator_Plugin\*.class", and since I get 47 errors I guess it does not load any other class.
thank you for you comments, the problem with having these errors, is that I can't even get a piece of information where this error is coming from, only that it is an import loading error package not found, what does that mean? that the jar was not loaded in compilation(no error about this), that the jar is corrupted(no error about this), that the path is incorrect(it is correct I made sure), that there is no such package in the jar(There is), that the compiler does not load the package(does it even do that?), really I can't even guess why this happens, I've been at this on and of all day today, really annoying.
Thanks,
Adam.

How can i get the path to config folder placed inside the jar file?

Hi i have developed an RCP application using eclipse.
In my application config directory is there.
When i export my RCP application as JNLP Project the jar file is created which contains config folder inside it.
When i download the application using java web start , how can i get the path to config folder placed inside the jar file?
Will the config folder exists in local cache in my system?
Help needed.

Are JDev autogenerated paths needed to create ear, war and jar files ?

Hi
We want to create ear, war and jar files from Ant build script generated from JDeveloper 11.1.1.7.
We also like to use ojdeploy with it.
In the process of creating build.xml files from projects, we see these paths.
We also have standalone Weblogic installed with ADF runtime 11.1.1.7
Questions:
1- Do we need these path ids to generate ear, jar, war files properly and then deploy the ear to our standalone Weblogic so that our webapp can run ok ?
2- Why are they generated, if they are not needed
From research, it appears that we don't need these paths except to keep ant targets of init, compile, exec etc with ojdeploy.
3- Is that true ?
We are afraid that because no paths are listed in the build.xml, then when we deploy the ear app, it cant use the ADF runtime on the standalone WLS.
Thanks in advance for answering.
Sincerely
eg of paths generated below:
<path id="library.SOA.Designtime"/>
<path id="library.SOA.Runtime"/>
<path id="library.BPEL.Runtime"/>
<path id="library.Mediator.Runtime"/>

There are two different things here. Using ant to build the class files and then building an ear from the class files and other resources.
The building part needs the libraries if you use javac as compiler. Building an ear file only needs the path to the jar files which are packed into the ear.
In this sense you need the pages you see in the build.xml.
Then Jdev offers another way: ojdeploy. This tool is a Jdev without a gui.
You can use this tool and build the classes for each project of a workspace and to build build war and ear file. This is just like you click the rebuild button for each project and then the deploy the projects and application. If you use this approach you don't need the generated path ids as the whole build process is done inside Jdev as it's done on your developer pc.

How to determine the path of the jar file cache of javawebstart?

Hello, I need to know how to determine where the java web start application
file jar cache is stored on windows system hard drive.
I would have launch of the inner processes
I have need to know the path of file jar .
example if my application is myAppliation.jar
in code generic class of myAppliation.jar i have the command runtime
String strCmd =
System.getProperties().getProperty("java.home") + "\\bin\\java" +
     " -cp " +
     System.getProperties().getProperty("java.class.path") + ";"
     + " anotherClass.class ";
Runtime.getRuntime().exec(strCmd);
the anotherClass.class has need
of the contained library in myAppliation.jar.

Thanks i have tried this metod and function
java.net.URL resource = classLoader.getResource("myResource");
if (resource != null) {
String s = resource.toString();
if (s.startsWith("jar:")) {
int index = s.indexOf("!");
if (index > 4) {
String fileurl = s.substring(4, index);
if (fileurl.startsWith("file:")) {
String path = fileurl.substring(5);
// now path is the path to the jar file in the cache containing the resource
System.out.println("file jar: "+path);
}

Adapter module:: JAR file in the build path of EJB project

Hi Experts,
I have created one adapter module, for this I have created one EJB project and also associated one EAR project to that.
I have completed my coding and changes in the xml files.
I have followed this -
http://www.sdn.sap.com/irj/scn/index;jsessionid=(J2EE3417500)ID1494558950DB01504425675464955468End?rid=/library/uuid/c0b39e65-981e-2b10-1c9c-fc3f8e6747fa&overridelayout=true
while creating the module.
but after finishing this , I can not see the ejb.jar file corresponding to the ejb project, I can see the class file generated in the build path.
but I can not see the ejb.jar in the EJB project after build.
When I checked the EAR project I found under Deployment descriptor there is a folder called module and there is a jar file named as -
EJB<my ejb project name>.jar
when I am about to deploy this EAR in the server it is showing me to choose the file from EAR project and this EAR project contain the EJB Project .
Request you to please let me know is everything ok with my project ? or please let me know how can I see the ejb.jar file corresponding to the ejb project below the build path.
Thanks
Vinny
