  • Unable to access jar file error !

    hello,
    i have built my netbeans project and obtained the hequalifies.jar file . unfortunately when i'm trying to run this jar file from the prompt command I'mgetting the error: unable to access jar file
    here is the command i'm typing:
    C:\Users\User\Documents\NetBeansProjects\hEqUALIFIES\dist>java -jar " C:\Users\U

    anyone has any clue?
    10x!

    ok i'm gonna make it easier on you.
    i gess i found what is the problem but have no idea how to solve it.
    when i obtained the .jar file i also obtained a README.txt file in which it is written the following phrase:
    ** If a library on the projects classpath also has a Class-Path element*
    specified in the manifest,the content of the Class-Path element has to be on the projects runtime path.
    I'M SORRY BUT I DID NOT UNDERSTAND WHAT IS MEANT BY: what is "the projects runtime path"?
    the content of my manifest is:

  • Error message at start-up Unable to access Jar file

    I am a consumer, not a business...and not an IT professional. I am running Vista and have not installed any new software recently.
    At every start-up, I get a pop-up titled Java Virtual Machine Launcher. The message says "Unable to access jar file". C:\users\user\.jnana.jnana.tsa.
    Any idea how to fix this?

  • Weird classpath issue in EAR.Some classes can access jars that others cant!

    Hi,
    I'm experiencing a very frustrating problem that's proving to be a bit of a show stopper for me. I would really appreciate some help...
    I have an EAR deployed successfully on Sun Appserver 8 which passes the tests from the sun EAR verifier tool. The ear contains a jar file that I built which has a stateless session bean, home, remote interfaces and rmi stubs, deployment descriptors, as well as some utility classes. The EAR also contains some third-party jars such as Hibernate, Log4-j, apache-commons etc etc. The jar I built has in it's manifest file, the classpath information to reference the other jars in the ear.
    The problem I am having is that one of the classes in a third-party jar (hibernate3.jar) cannot see a class in another of the third party jars (log4j-1.2.8.jar) and as a result is throwing a NoClassDefFoundError for org/apache/log4j/Layout while trying to initialise - the two jars are at the root of the EAR.
    Furthermore, my utility classes can access and use Log4j classes without any problem and logging command from those classes is output successfully to the server console. However, my session bean, which is packaged in the same jar as the utility classes, fails to log anything even though it uses exactly the same logger and log configuration as the utility classses.
    I have tried adding classpath information to the manifest of the EAR so that the third-party jars can pick it up but this makes no difference. Also, according to the EAR verifier tool, you are not allowed to put any classpath information in the EAR manifest.
    I have also tried deploying this in weblogic but am experiencing the same problem.
    If anyone can offer any advice or solutions I would greatly appreciate it.
    :)

    what´s type error have you?
    perhaps external libraries (located in classpath) invoke opsCommon.jar and config-3.0.jar classes. then, classnotfound is normal.
    and... why separate external libraries (opsCommon.jar and config-3.0.jar inside ear, and other in classpath)?

  • 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.

  • How to access jar files

    Hello,
    I've created a web application using servlets and jsp.
    Under Tomcat/webapps dir, I created my project dir and copied jsp files there, whereas copied all the java and class files under webapps/projectdir/WEB-INF/classes/mypackage. I also created a web.xml file under WEB-INF dir with my servlets mapping. I aslo created a lib dir under WEB-INF and copied jstl.jar and standard.jar in there. So far my application runs fine.
    Now I've to include some jar files that will be providing data from the backend to my servlet. I can't have .class files instead of .jar files, that is the restriction the way the backend files are built.
    Can anyone tell me how to make Tomcat access those jar files.
    Thanks.

    Ok then. I think the page you should read is [Tomcat 5 classloader documentation|http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html], though they simplified the structure in [Tomcat 6|http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html].
    Normally the classpath of a web application is restricted to
    - WEB-INF/classes directory
    - jar files in WEB-INF/lib
    - jar files in the server /lib directory.
    So if you have a common library that is used by multiple web applications, you could give each web-app their own individual copy of that library in WEB-INF/lib, or you could have them all use the same one in the server lib directory. There are pros and cons to both approaches.

  • Accessing Jar contents

    Hi everyone,
    I'm sorry to ask such a dumb question, but I'm still e newbie with Java.
    Ok here goes:
    How can I access the contents of a Jar file, for example images in a package, like:
    com.mypackage.images ----> images that I need to access.
    I used the example of images for simplicity but the contents of the jar file could be anything, like database drivers, or other classes.
    Thank you in advance.
    Chris

    It's really quite easy; if your entire application is in the same jar-file it will be just as if you weren't using jars at all. To use classes in a different jar-file, that jar-file just has to be put in the classpath-variable, and all the classes inside will be accessible.
    Not sure what you meant about the images - if you were talking about a class named images, a package or actual images to be loaded. In the latter case, there are a few differences from otside of a jar-file:
    // If your images are outside the jar:
    Image img1 = Toolkit.getDefaultToolkit().getImage("nameOfImage.png");
    // If your images are inside the jar:
    Image img2 = Toolkit.getDefaultToolkit().getImage(getClass().getResource("nameOfImage.png"));

  • Question about asp access

    Hi.
    I'm trying to get information from a MS Access database to a Java applet. I think the easiest way to do this is to use ASP. I got the asp page working to access the database and print its contents but I have no idea how the applet can access that information. I know nothing about asp and got the connection code from a tutorial. Can anyone tell me how I can access the information from a Java applet?
    Thanks in advance.
    ASP code follows:
    <%
    Set MyConn = Server.CreateObject("ADODB.Connection")
    MdbFilePath = Server.MapPath("db1.mdb")
    MyConn.Open "Driver={Microsoft Access Driver (*.mdb)}; DBQ=" & MdbFilePath & ";"
    SQL_query = "SELECT * FROM Table1"
    Set RS = MyConn.Execute(SQL_query)
    WHILE NOT RS.EOF
    %>
    <LI><%=RS("Name")%>: $<%=RS("Balance")%>
    <%
    RS.MoveNext
    WEND
    %>

    Thanks, I've gotten the reading working. But I'm a
    little confused on how I would update. If I wrote an
    asp page (say...called update.asp) that updates the
    database, how would I call that from java? You
    wouldn't use an input stream would you?Same way. Don't confuse the input stream with "input to a database". It's just the response from the service, and also the way to actually get the service (URL) to be invoked. Of course, for updating the database, you're probably going to want to pass the service something, telling it what to update. Passing it something is done (or can be done, as one way) by putting the information on the URL, like:
    http://some/path/update.asp?key=abc&newValue...
    And if you have any links to tutorials on asp database code,
    that would be awesome. Thanks.I'd suggest using good-old google: http://www.google.com to search for those keywords.

  • Accessing JAR file

    How i can access a file inside my JAR? Anybody there to help me?

    Touchy subject.
    Look in the [java.util.jar|http://java.sun.com/j2se/1.4.2/docs/api/java/util/jar/package-summary.html] package to get ideas. You might also want to check google for "java unpack jar" and use that to read files.

Or why you should do that. Or how you should do that. Because that particular piece of advice isn't just ridiculous-sounding, it's just plain ridiculous.
    Or it's possible you weren't really given ridiculous advice, it's possible you misunderstood. In which case asking the person who gave you the advice to clarify it would have been a good strategy too.

  • Can CF and ASP Access the Same Database?

    Hello. I'm about to go into beta with a ColdFusion 8 site I
    just wrote, and I've just realized there could be a problem I
    haven't anticipated. There's another site, written in ASP, which
    will accessing the same data at the same time. The data are in
    FoxPro for DOS, which (if I have the terminology right) is a 'file
    server' database. Both my site and the ASP site will be accessing
    it through ODBC. I will be accessing it on a read only basis, and I
    believe the ASP site accesses it read only as well. However, other
    employees in the company are constantly accessing it read/write.
    The ASP site has been already up and running for some time,
    and the office manager (it's a small company) finds that he is able
    to avoid conflicts by first stopping the ASP server each morning,
    then starting FoxPro, then re-starting the ASP server. (I do not
    mean the IIS server, but a little EXE written by the ASP
    programmer, which puts up its own little window with 'start' and
    'stop' buttons on it.)
    However, I find that on my own PC, using the free Developer
    version of ColdFusion and accessing my site as localhost, if a DBF
    (database file) is opened in FoxPro (even if no one is currently
    writing to it), then my CF web site cannot access it, and vice
    versa. That is, if I start FoxPro first and open the DBF of
    interest, my web site can't access that DBF. And conversely, if I
    access it first via my web site, then FoxPro can't access it. In
    other words, the solution which works for the office manager and
    his ASP site does not work for me with CF on my local PC.
    Will matters be different in their system, where I will be
    installing my site tomorrow, along with the Standard version of CF
    8? If it matters, the FoxPro data and the Web server will be
    different boxes linked by a network. The operating system is
    Windows 2003 if I recall correctly.
    Should I be saying 'Oops!' right about now?
    I can probably come up with a workaround by having FoxPro
    write a record to an alternate DBF every time the DBF of interest
    to my site is updated, but will I have to do this?
    Thanks for your help.

    Not much that can be done to make the database robust and
    handle
    simultaneous transactions. But you could wrap all your CFML
    that
    accesses this resource in named <cflock ...> tags so
    that they are
    single threaded, thus restricting CF to one access at at
    time. Then
    wrap all of this up in a <cftry><cfcatch...>
    blocks to gracefully handle
    when the database is locked up by some other user/process.
    You will still have many times when the CF application will
    not be able
    to access the resource do to locking issues, but it will
    handle this
    gracefully and not just FAIL.
    Of course this will have serious performance, throughput and
    scalability
    consequences. But I suspect if you are using something like
    FoxPro you
    are not building an application expected to handle heavy
    load.

  • Access JAR File while running App with Java Web Start

    Hello guys,
    I want to delpoy my application so that I can run it when I click on the appropriate button in a web page.
    I have a Jar file for all the files that the app needs. No, not all of the files are included.
    Indeed, I use JAR files such jdom.jar or postgres...jar that I must use in within my application.
    How can I access these JAR files knowing that I can't point to files in a JAR file A from within a JAR file B, if the JAR file B contains the JAR file A?
    The main JAR file that I put on the web server can be seen as the JAR file B and the other JAR files must be stored somewhere for the java classes within the main JAR file to have access to them.
    I wonder whether there is another way to structure the project.
    Thanks.

    Hi Andrew.
    I have followed your suggestions and here is what my .jnlp file look like:
    <tt>
    <?xml version="1.0" encoding="utf-8"?>
    <jnlp spec="1.0+" codebase="http://localhost:8080/koedops" href="beta.jnlp">
         <information>
              <title>KOEDOPS</title>
              <vendor>Pr. Fischer</vendor>
              <homepage href="http://localhost:8080/" />
              <description>Downloading koedops with Java Web Start</description>
         </information>
         <resources>
              <j2se version="1.6+" />
              <jar href="beta.jar" main="true"/>
              <jar href="jcalendar-1.3.3.jar" />
              <jar href="jdom.jar" />
              <jar href="postgresql-8.4-701.jdbc4.jar" />
         </resources>
         <application-desc main-class="general.Application" />
    </jnlp>               
    </tt>
    The three other jar-files reside in the same directory as the .jnlp file and the beta.jar file on the tomcat server.
    When I launch the application though nothing happens upon the download. In contrast, if I change the main class to a class file that requires no extra library, it runs perfectly.
    I can't be sure whether the jar-files are successfully accessed.
    Regards.
    Edmond

  • Accessing jars

    Using oracle AS 9.04. An app I have inherited used to access some jars via
    <library path="../applications/<app_name>/<example.jar>" /> in server.xml.
    Can I do the same at 10g by moving the xml configuration to the system application file?
    thanks

    Which version of 10g -- there's R2 (10.1.2) and R3 (10.1.3).
    The tag is still valid in R3, but I'd encourage you to look at using shared-libraries instead of this approach -- you can deploy your JAR(s) as a named/versioned shared-library and then import them into the default application (ie j2ee/home/config/application.xml).
    We don't recommend modifying the system-application.xml file -- it's largely an internal construct. Use the application.xml file instead which is the config file of the default application and thus the visible parent of all deployed applications.
    cheers
