  • How to use the COMM API in a JAR file

    I have developed an application, using the NetBeans IDE, to communicate with a modem over the COM1 serial port using the Java Comm API. The application works fine within the IDE, but when a JAR file is created and "double-clicked", the application launches correctly, but when the code is executed to "talk" over the COM1 serial port - nothing happens. No exceptions and no warnings are thrown. My environment is XP, SP1.
    The manifest file is as follows:
    Manifest-Version: 1.0
    Class-Path: ../j2sdk1.4.2/jre/lib/ext/TimerBean.jar ../j2sdk1.4.2/jre/
    lib/ext/AbsoluteLayout.jar ../j2sdk1.4.2/jre/lib/ext/comm.jar
    Created-By: NetBeans IDE
    Specified-By: Projects/TheApp/Files/TheApp.jarContent
    Main-Class: Main
    According to the Comm API installation instructions, the following files are copied:
    copy comm.jar \j2sdk1.4.2\jre\lib\ext
    copy wind32com.dll \j2sdk1.4.2\bin
    copy javax.comm.properties \j2sdk1.4.2\jre\lib
    I suspect it has something to do with the paths.
    Any help would be greatly appreciated. Thanks.

    Thanks for your input, but after trying what you suggested the problem still exists. I think your right to be suspicous of the javax.comm.properties file. The application, that worked in the IDE, exhibits the same behavoir as the JAR file if the javax.comm.properties file is removed from the ../jre/lib directory. In other words it compiles correctly in the IDE, but when executed, nothing happens when the code that "talks" to the serial port is run.
    I've tried moving the javax.comm.properties file into the working directory. Also, the CLASSPATH and PATH system variables were modified to include the path to javax.comm.properties.
    If you have anymore ideas, please let me know.
    Thanks.

  • What is the command to create a jar file through Command Promt?

    Hi,
    I done my java project. Now i need to create a exe or jar file to fully complete it. I decided to create a jar file. Because, It'll support both PC and MAC. I exported my JAR file through eclipse. But that jar file loads without images and icons when it is in other directory. How can i include images folder in a JAR File.
    For ex:
    I have parent folder named "Support". Under this there is 3 subfolder namely
    bin - Classes
    src - java files
    images - image files.
    I need to create jar file to "Support" folder which should contain all the above mentioned sub folders.
    I need to execute this jar file anywhere which should not depend on the above mentioned folders which mean adding the images folder in that created jar file.
    Pls guide me for this problem.
    Thanks in advance
    Regards,
    Mohan

    But that jar file loads without images and icons when it is in other directory.Images should be accessed via a URL rather than using a filename because they will exist as entries in the jar archive not as files. Typically this URL would be obtained by using the Class method [getResource()|http://java.sun.com/javase/6/docs/api/java/lang/Class.html#getResource(java.lang.String)]. There are details in this [Java World article|http://www.javaworld.com/javaworld/javaqa/2002-11/02-qa-1122-resources.html].

    Krishna,
    It is not possible to deactivate the CHANGE option in themenu bar using the method disable_functions of cass CL_CTMENU. This method allows you to deactivate only the function codes of the CONTEXT MENU, which is available only when u press the left mouse button.
    U can use the SET PF-STATUS 'XXX' EXCLUDING fcodes option to disable the CHANGE.

  • Taglib: class not found in jar-file

    I've got the following problem:
    I whant to deploy a taglib to tomcat 5.0.25.
    If I point to the jsp which uses the taglib I got the following error:
    org.apache.jasper.JasperException: Unable to read TLD "META-INF/taglib.tld" from JAR file "file:/C:/Programme/Apache Software Foundation/Tomcat 5.0/webapps/taglibtest/WEB-INF/lib/gsa_prod3_db_taglib.jar": org.apache.jasper.JasperException: Failed to load or instantiate TagExtraInfo class: ch.gsa.prodass3.taglib.TagAddAttributeTEI

    Has anybody an idea?
    Help would be very appreceated!
    Greetings, Jonas

    1 - double check the class is in the jar file, in that path, and is spelt correctly
    2 - restart Tomcat
    3 - check the contents of the tld file - particularly the extra-info tag and class name for it.

  • Problem in include library files into my jar file

    i am new to this jar archiving...I have created a GUI with java swings..and i also use mysql driver to connect my database now i want to make an executable jar file for my GUI..with coonector i have done the following

    next i ran jar cmf mainClass.txt example.jar *.class mysql-connector-java-3.1.10-bin
    With this line, I told jar to create a JAR file (option c) with modifications to the manifest file (option m) as specified within mainClass.txt, naming the JAR file (option f) as example.jar and including everything that matches the pattern *Class and mysql connector
    now my problem is ...my MYSQL connection need some Library files from a package called org and class Driver.class to generate connection I include this library files also in my example.jar....

  • Problem loading image from jar file referenced by jar file

    First, I searched this one and no, I didn't find an answer. Loading images from jar files has been pretty much done to death but my problem is different. Please read on.
    I have my application, a straight up executable running from Eclipse. It uses a jar file, call it JarA. JarA launches a GUI that is located in another jar file. Call it JarB. To recap:
    My application calls JarA -> JarA loads classes from JarB -> JarB looks for images to place in a GUI it wants to show on the screen
    When JarB goes to load an image the following happens:
    java.lang.NullPointerException
         at sun.misc.URLClassPath$3.run(URLClassPath.java:316)
         at java.security.AccessController.doPrivileged(Native Method)
         at sun.misc.URLClassPath.getLoader(URLClassPath.java:313)
         at sun.misc.URLClassPath.getLoader(URLClassPath.java:290)
         at sun.misc.URLClassPath.findResource(URLClassPath.java:141)
         at java.net.URLClassLoader$2.run(URLClassLoader.java:362)
         at java.security.AccessController.doPrivileged(Native Method)
         at java.net.URLClassLoader.findResource(URLClassLoader.java:359)
         at java.lang.ClassLoader.getResource(ClassLoader.java:977)
         at org.cubrc.gmshell.gui.MainWin.preInit(MainWin.java:152)
         at org.cubrc.gmshell.gui.MainWin.<init>(MainWin.java:135)
    The code from JarB that loads the image looks like this:
              URL[] oSearch = {Main.class.getResource("images/")};
              URLClassLoader oLoader = new URLClassLoader(oSearch);
              imgIcon = new ImageIcon(oLoader.getResource("icon.gif"));
              imgMatchRunning = new ImageIcon(oLoader.getResource("gears.gif"));
              imgMatchStill = new ImageIcon(oLoader.getResource("gears-still.gif"));
              imgMagnify = new ImageIcon(oLoader.getResource("magnify.gif"));This looks right to me and JarB certainly has an images directory with those files. But I'm in hell right now because I don't know where to place the images to make this work or if you can even attempt to load images with a dependency chain like this.
    Any help very appreciated!

    Have you tried to move your image-files out of the jar file and place them in the sam folder as the jar-file? I think that would help.
    When you try to load the image-file you get the NullPointerException because the program tries to read a file it can't find. Remember that a jar file IS a file and not a directory.
    If you want to read somthing inside the jar-file you need to encode it first.
    Have you tried to read the jar-file with winRar. It makes it easy to add and remove files in your jar-file.

  • Strange problem with my ClassFactory when a non used jar file is missing.

    Hello,
    I have a small problem regarding a class factory and I don't really understand how to solve it.
    If you see the example below we can imagine that I have a classFactory who can provide 3 different types of classes.
    public class ClassFactory {
    public ClassFactory() {
    public static Service getClass(String szType) {
    if(szType.equals("1")) {
    return new Class1();
    } else if (szType.equals("2")) {
    return new Class2();
    } else if (szType.equals("3")) {
    return new Class3();
    else {
    return null;
    My problem is the following. Let�s imagine that Class1 and Class2 do not use specific jar file but Class3 uses a jar file which is not always present in old installation.
    I thought that it was possible to get this factory running correctly if the customer only uses Class1 and Class2 same if specific jar file used by Class3 was not present but this is not the case.
    I remarked that if the specific jar file used in Class3 was not present in my classpath the ClassFactory is blocking (same if we do not try to get a "Class3").
    My problem is that I want to keep my code backward compatible without asking the customer to add a new jar file only used in new installation.
    Can anyone of you explain me why it is reacting like this and how can I solve this problem?
    Thank in advance for your reply.
    Alain.

    There's a standard way of handling these things now. You place a text file in each jar that contributes candidate concrete classes with the FQN of an implementing class on each line. Your factory class then collects all these using getResources() on the context class loader and loads the classes dynamically.
    The text file goes in the diretory META-INF/services and the file name is the FQN of the interface or abstract class they all implement.
    Typically there's a small factory class for each implementation and you ask each, in turn, whether they accept the specifications the caller requested of your factory (typically static getInstance() method).
    Or you could, for example, put the selection name/index or whatever in each class as an annotation.

  • Beginner: Can't convert a hello.class file into a jar file: HELP PLEASE!!!

    Hi, I created a hello.java file, converted into a hello.class file by using the java 2SDk compiler. The problem is that the hello.class file is in a directory I created: C:\JavaBuilder\hello.class
    I have a problem converting the hello class file into a jar file. I don't know which approach to take. I've looked at tutorials...but I keep getting more confused each time I view the tutorials on creating jar files. Please can someone help..by taking me through a step by step process. Please be explicit and do not leave or assume that I know any details because I'm a new born beginner. Thank you very much, I seriously appreciate it.

    Hi i did as you suggested, only with these exceptions:
    jar -cvf hello.jar C:\JavaBuilder\hello.class
    I did this and got the message: "adding : C:\JavaBuilder\hello.class (in=1150) (out=708) (deflated=38%)"
    The problem is that when I tried to execute the jar file...by typing: " java -jar hello.jar" I received the error message: "Failed to load Main-Class Manifest attribute from hello.jar" Is there any way to correct this problem? please help, thank you.

    Hi!
    first of all, you should use an upper-case character for the first letter of your classes...
    To answer your question :
    1) you must create a directory named "meta-inf" in your directory "C:\JavaBuilder"
    2) then,you must create a file named "manifest.mf" in this directory
    it's like a property file and it must contain this :
    Main-Class: hello
    (don't forget to type <enter> after "hello")
    3) in the directory "C:\JavaBuilder", you can enter the following command :
    "jar cvfM hello.jar meta-inf\manifest.mf hello.class"
    (check jar.exe is in your path)
    4) you can run your jar by the command :
    "java -jar hello.jar"

  • Unable to access classes in third party jar files packaged with my ejb.jar

    I have packaged some third party jar files in my xxx_ejb.jar file.  The third party jar file contains classes that are accessed by some custom classes which are in turn accessed by my bean classes.  I get the following error when my custom classes attempt to use any of the classes in one of the third party jar files:
    java.lang.NoClassDefFoundError: com/Ostermiller/util/CSVParser
    Shouldn't I be able to access classes in jar files that are packaged with my xxx_ejb.jar file?  I see the xxx_ejb.jar file as a resource of the application classloader that contains it but I don't see the third party jar files.

    As per the Java EE specification, additional JAR files should be packaged on the EAR level. Only WAR files' WEB-INF/lib folder is scanned for JAR files to be added to the classloader.

    Why is everyone so obsessed with doing this? The gains are minimal and the problems numerousBecause we are new and don't understand how the java VM actually runs code and the error messages sent by the java machine are cryptic.
    My first attempt at using an external jar in a java program lead me to believe that all of the code for a java program would be in a jar file including external jar files, after all the JDK standard library has tons of jars in it so I assumed the external jar file would be linked (as most other programming compiler/linkers I have worked with in my top down programming life).
    I find out the answer is so simple that the external jar file could not be found by the VM running my jar file. Like I said, if the VM would have just gave me an error that it could not find a file on a specific directory i never would have perused the idea of jar in a jar (fatjar plugin for Eclipse for example)
    Really this is like getting into a race car and not knowing at what RPM to shift gears, sure you can press the pedal and make it go but if you don't understand how it works under the hood you are going to blow the engine if you keep it in first gear.
    I have read many posts on these errors, the reason is the error message is just not very descriptive of the original problem. If I try and open a database called xyz.dbf that has one field defined as lastname, in C for example, I would not give the error message "Lastname could not be found) when indeed the lastname could not be found but the reason it could not be found was because the database xyz.dbf could not be found. Further , adding to the error message that the system is looking for xyz.dbf on drive X- subdirectory -mydatabases would complete the error message and allow the user to fix the error. Just what is a non java programmer that is using my java program suppose to do with an Ecception Error in (main) bla bla bla... I know now I need to check for library files myself within my own java programs and give a better error message to the user before the java VM sends out it's cryptic message.

  • Reading an xml file from a jar file

    Short question:
    Is it possible to read an xml file from a jar file when the dtd is

    Long Question:
    I am trying to create an enterprise archive file on Weblogic 6.1. We
    have a framework that is similar to the struts framework which uses it's
    own configuration files
    I could place the dtd files outside the jar ear file and specify the
    absolute path in an environment variable in web.xml which is
    configurable through the admin console.
    But I want to avoid this step and specify a relative path within the jar
    file.
    I have tried to use a class which implements the entityresolver as well
    as try to extend the saxparser and set the entity resolver within this
    class explicitly, but I always seem to sun into problems like:
    The setEntityresolver method does not get called or there is a

  • File objects in jar file

    Hi!
    Is their some kind of way one can use File objects in a jar file plz? I have a project which is complete and working well on the IDE but now that I have jarred it, i've come to realize that apparently file objects do not relate well with .jar files. The problem is that the program makes a lot of file manipulations and changing everything to getResource, InputStream etc would be very lengthy. So there's absolutely no way in which one can use File objects in jar files?
    Any help would be very much appreciated!
    Thanks and regards,
    Krt_Malta

    You can use the java.net.JarURLConnection class (use file:/// when creating the URL) to get a URL to a jar entry, create a URI from the URL, and then create a File object on the URI.
    Or use java.util.jar.JarFile methods and its associated classes to get jar entry contents.
    While you can use these approaches to create File objects from a jar, they are not any easier than what's already been mentioned.
    And all you can do is read or delete a jar - jar entries can't be rewritten.
