Added JAR files are removing while Building

Dear Gurus,
I will explain my problem.
I am developing a portal standalone application.There I have to read one Excel file.
So I used 'jxl-2.6.jar' which was not available in the server.
I have created one external library project and uploaded respective jar to server.
I have checked the same in visual admin as per blog  "http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/2361"
and it was fine.
Now my problem is if I build my project, it is showing the error in import statement.
I have tried these all
1) added that jar as used DC
2) added the library project as project reference
3) in Java build path i have added 'Add JARs'.
When I am adding this no error but when i build, it will show error and it is removing this jars from Java build path.
Thanks in advance,
Ram

The problem Solved.
The issue was with assembly and compilation part while adding to public part.
this link is having good info

  • Jar files are not exported while PAR Export

    Hi Experts,
    When  I am exporting as PAR file, in the par file  I am not getting the jar files, which I am adding as external jar files in the java build path - Libraries
    Please tell me the solution. urgent...
    Regards,
    Shyam

    Step 6 makes your third party jars available during runtime on your server since you put the dependency to runtime. I don't think you need/can reference your j2ee server dc in the portalapp.xml.
    Summary of the link I sent you:
    1. Create an External Library DC
    2. Copy all of the Jars I needed to the libraries folder of this DC
    3. Create two Public Parts (right click on the jar files in Package Explorer)
          i) compilePart (with purpose compilation)
          ii) assemblyPart (with purpose assembly)
    4 Create a new DC of type J2EE Server Component / Library
    5. Add a Used DC to the J2EE Library, reference the compilePart from previous step, and set Dependency type to Build
    6. Add another Used DC, reference the assemblePart, this time select both Build and Runtime Dependency Types
    7. Build and deploy.

  • The Apache axis2 jar files are not taking at run time

    While running the application I was getting the following errors. The error is getting at run time only. It has compiled successfully.
    It ran under eclipse without any issues. But with Apache axis we are getting following error trace while uploading to server. The Apache axis2 jar files are not taking at run time.But compiling successfully.

    Hello,
    I too am trying to use Axis2 application in R12. But getting the following error:
    java.lang.classCastException: com.sun.xml.messaging.saaj.soap.ver1_1.SoapMessageFactory1_1Impl cannot be cast to oracle.webservices.soap.VersionedMessageFactory
    If I run the application standalone from java command line it works fine. I think the error could be because of some oracle app jars getting picked up inatead of my application jars. How to make sure that my application jars get picked up instead of oracle jars
    I tried loading my jar file and then setting it as contextClassLoader using "Thread.currentThread().setContextClassLoader", but this did not help.
    Can you please let me know what can be tried to fix this
    Thanks

  • Update jar file by removing existing files

    hello,
    is there a way to update a jar file by removing indicated files within the jar file ?
    I saw that it is possible to update a jar file by adding files to it: jar uf jar-file input-file(s)
    I want to avoid:
    1)extracting the file
    2) remove indicated files
    3) compress again.
    thank you !

  • Error 8 File permission error while building executable for a RT

    I got error 8 File permission error while building executable for a RT. It happened always after build, I mean new startup.rtexe and startup.alias files have been created. At the build properties, it was set use default .alias file.

  • How to detrmine what directory you (the JAR file) are in

    Is there some sort of function that returns (ideally in a string, or array of strings) what directory you (the JAR file) are in? Something along the lines of:
    String dir = Function();Then dir would be something like : "C:\Users and Settings\Me\Java Apps"
    Thanks.

    It's not clear exactly what is wanted. Look at the information in the API for java.lang.System,getProperties(), which lists properties available - choos the one you want.

  • Adding Jar files in another Jar file

    Hi,
    I have a very bad problem. Please some one help me here.
    I created a Java application which is organized in a package structure.
    The directories and files in the JAr files are following
    1) TestApplication.class - The application startup class.
    2) com(dir) - The start of my package structure, all the othere files are in this directory
    3) config (dir) - Directory containing all the configuration files.
    4) hsqlDatabase (dir) - contains the inprocess database
    5) images (dir) - Contains all the images used in the application.
    6) lib (dir) - Contains all the other jar files that i use in this application, i have about 10 of them in this directory.
    I created a jar file which contains all these dir and the TestApplication.class file. I also uses the 'Main-Class' and 'Class-Path' attribute.
    This is my META-INF\MANIFEST.MF file
    Manifest-Version: 1.0
    Ant-Version: Apache Ant 1.6.1
    Created-By: 1.4.2_03-b02 (Sun Microsystems Inc.)

    When i try to run the application through
    java -jar xxxxx.jar
    1) the first problem is that it starts the application (TestApplication.class) and also loads the rest of the application in my package(com\...). But it cannot find the classes which are in the jar file (in the lib dir).
    2) I am also trying to read from a config\xxxxx.properties file, but i get an exception showing FileNotFound (xxxxx.properties).
    Hope that this will help you to help with my problem,
    Thanks in advance,
    Jobby

    1) the first problem is that it starts the
    application (TestApplication.class) and also loads
    the rest of the application in my package(com\...).
    But it cannot find the classes which are in the jar
    file (in the lib dir).
    jars inside of jars do not work like you want them too. You should be able to write a class loader that can find those other jars, but Java does not directly support jars inside of jars. Of course, you can unjar the other jars and use them as well.
    2) I am also trying to read from a
    config\xxxxx.properties file, but i get an exception
    showing FileNotFound (xxxxx.properties).
    Is this file also in the jar? If it is, you need to use getClass().getResource() to find the file.

    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

    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.

  • Adding jar file in my gerareted jar file using netbean 4.0

    Hi,
    I write an application de process XML file using JDOM. I add the JDom package jar file to my project and everything work fine. But when I generate, my project jar file using netbean 4.0, my generated jar, is not working with the XML files anymore. Everything seems like it didn't include the JDOM jar file?
    Thanks for any help to fix the problem.

    I find that you can not use command-line such as java -classpath add classpath
    it can not work, I use netBeans4.0 i don't whether because of netbeans or java itself.
    you can add classpath in jar's Manifest.mf file
    Manifest-Version: 1.0
    Ant-Version: Apache Ant 1.6.2
    Created-By: 1.5.0_01-b08 (Sun Microsystems Inc.)
    Main-Class: chat.Main
    // add this line
    Class-Path: dir\*.jar //(jar file name)
    X-COMMENT: Main-Class will be added automatically by build

  • JWS application jar-files are downloaded almost every time

    hey,
    how can i debug the situation, where my application is downloaded very often (even if i havent updated all of the jar-files, they are all downloaded again)?
    can it be that they expire after a certain time? how can i check that?
    thanks,
    Mait

    There are jnlp parameters that can be specified that define when jars are downloaded. This information is in the JWS documentation.

  • Why multiple  log files are created while using transaction in berkeley db

    we are using berkeleydb java edition db base api, we have already read/write CDRFile of 9 lack rows with transaction and
    without transaction implementing secondary database concept the issues we are getting are as follows:-
    with transaction----------size of database environment 1.63gb which is due to no. of log files created each of 10 mb.
    without transaction-------size of database environment 588mb and here only one log file is created which is of 10mb. so we want to know how REASON CONCRETE CONCLUSION ..
    how log files are created and what is meant of using transaction and not using transaction in db environment and what are this db files db.001,db.002,_db.003,_db.004,__db.005 and log files like log.0000000001.....plz reply soon

    we are using berkeleydb java edition db base api, If you are seeing __db.NNN files in your environment root directory, these are environment's shared region files. And since you see these you are using Berkeley DB Core (with the Java/JNI Base API), not Berkeley DB Java Edition.
    with transaction ...
    without transaction ...First of all, do you need transactions or not? Review the documentation section called "Why transactions?" in the Berkeley DB Programmer's Reference Guide.
    without transaction-------size of database environment 588mb and here only one log file is created which is of 10mb.There should be no logs created when transactions are not used. That single log file has likely remained there from the previous transactional run.
    how log files are created and what is meant of using transaction and not using transaction in db environment and what are this db files db.001,db.002,_db.003,_db.004,__db.005 and log files like log.0000000001Have you reviewed the basic documentations references for Berkeley DB Core?
    - Berkeley DB Programmer's Reference Guide
    in particular sections: The Berkeley DB products, Shared memory regions, Chapter 11. Berkeley DB Transactional Data Store Applications, Chapter 17. The Logging Subsystem.
    - Getting Started with Berkeley DB (Java API Guide) and Getting Started with Berkeley DB Transaction Processing (Java API Guide).
    If so, you would have had the answers to these questions; the __db.NNN files are the environment shared region files needed by the environment's subsystems (transaction, locking, logging, memory pool buffer, mutexes), and the log.MMMMMMMMMM are the log files needed for recoverability and created when running with transactions.

  • JNLP and jar files are being download from server again.

    I have a swing application deployed with Java Web Start on a server.
    On my client I install the application using JWS JRE 1.6.
    The issue is that without any change in the jars or JNLP the jars are being downloaded from the server again and again
    This is not consistant - it happens only sometimes.
    One important thing to mention: The server is inside a load-balancer cluster (AKAMAI), so the IP address of the actual server may change between different accesses.
    in the log, I can see the error:
    "Cache entry not found"
    and then the jar is being downloaded again.
    sometimes only one or two jars were downloaded again, sometimes the whole package with the JNLP file were dowloaded again.
    Can you suggest what can be the reason for this behavior?
    Thank you,
    Ran

    That does seem slow, but there are many factors that could be involved. More information would be helpful:
    - Are the source and destination filesystems ZFS or UFS? (or some other FS)
    - What does iostat show you?
    - What does vmstat show you?
    - What type of HBAs connect you to the SAN? ('fcinfo hba-port')
    - Anything in /var/adm/messages?
