Cloudscape question

I want to use Cloudscape of J2EE1.3.1,so I set classpath=.;F:\j2sdkee1.3.1\lib\system\cloudscape.jar then I enter into directory of F:\j2sdkee1.3.1\lib\cloudscape, and start Cloudview like follow command:
F:\j2sdkee1.3.1\lib\cloudscape>java -classpath cloudview.jar COM.cloudscape.tools.cview
I found I can start Cloudview GUI,then I want to create a new database,so I choose File->New Database,then I name a new Name,and press OK button,but I got following errors:

I know COM.cloudscape.core.JDBCDriver in the cloudscape.jar,and I have put it into classpath,why I still get above errors?
How to run cloudview for creating a new database?
Any idea will appreciated!
Best regards,
Edward

This sounds like a configuration issue regarding cloudscape rather than a java question.
I did a search on google which suggests the configuration is incorrect.

  • General Java questions

    1) A program written in Java is supposed to be multi-platform. However, I notice alot of programs I've seen written in Java are distributed to specific systems using different file extensions. The Windows version usually uses the .exe extension and I'm wondering how come they don't use the default .class extension? One major company is Borland for their JBuilder. They had a Windows version long before a Linux version even though I hear it was created in Java.
    2) Is there a free install program for Java or are the only ones commercial products?
    3) Is there a personal database available for Java that will work on all platforms? In my Internet Programming with Java class we used mySQL but I don't want to use a server database let alone one that will require a seperate install.
    4) Is there a free multi-platform IDE for Java (not counting just a text editor)?
    5) Can you universally access a system with Java? Ex. If I wanted to load an application with Java in Linux and Windows do I need to write two seperate routines on how to do this or does Java have a built in function? If I wanted to delete a file is this written universally the same?

    1) A program written in Java is supposed to be
    multi-platform. However, I notice alot of programs
    I've seen written in Java are distributed to specific
    systems using different file extensions. The Windows
    version usually uses the .exe extension and I'm
    wondering how come they don't use the default .class
    extension? One major company is Borland for their
    JBuilder. They had a Windows version long before a
    Linux version even though I hear it was created in
    Java.Java programs are packaged (wrapped) to allow invocation using a .exe extension. It is not mandatory, nor is it a function provided within the native Java libraries. Standard Java is packaged in .jar files that allow execution within a Windows (or other) environment. Environmental setup is necessary to allow the O/S to find the Java libraries. This is a simple process that includes additions to the PATH and CLASSPATH environment variables.
    2) Is there a free install program for Java or are the
    only ones commercial products? I believe installAnywhere has a stripped down version of an installer that you can use for free. They also have a pay-per version that provides more extensive functionality.
    3) Is there a personal database available for Java
    that will work on all platforms? In my Internet
    Programming with Java class we used mySQL but I don't
    want to use a server database let alone one that will
    require a seperate install.There are several Java embeddable SQL compliant databases including Cloudscape and Pointbase. These are written and deployed as Java libraries, and can run within the same JVM as your application or in a seperate JVM on the same machine, or on a seperate machine with IP connectivity. I'm sure there are more, these are just two that I have used. I don't know that there are any free implementations of embeddable databases for Java (but just wait awhile, things change all the time).
    4) Is there a free multi-platform IDE for Java (not
    counting just a text editor)?For personal use, there is Borland JBuilder personal that can be downloaded and used for free. I personally use Sun ONE Studio CE (formerly Forte for Java) which is also free but uses a lot of resources, so be sure you have an adeqaute workstation to run it on. Again, I'm sure there are others, these are just the ones I have had success with.
    5) Can you universally access a system with Java? Ex.
    If I wanted to load an application with Java in Linux
    and Windows do I need to write two seperate routines
    on how to do this or does Java have a built in
    function? If I wanted to delete a file is this
    written universally the same?I'm a little unclear on your question, but you can invoke a seperate process (application) from Java using the O/S native interface through a Java function call. A seperate method is probably not necessary for each O/S, just different parameters passed to the exec function.
    File I/O and file manipulation can be done using Java, and does not have to be O/S specific (but you have that option if you want to).

  • Cloudscape in weblogic

              Hi,
              I am trying to run a sample application using cloudscape in weblogic. I am
              trying to create some stored procedures in cloudscape. I looked in the manual
              and was unable to find it. I have basicall two questions.
              1. How is cloudscape started in weblogic.
              2. How do you include the classes that you created in the cloudscape database.
              (I did try including in the jars of cloudscape but was not successful)
              thanks,
              babu
              

    It looks like the server is unable to locate the cloudscape JDBC driver.
    You should make sure that it is in your class path.

  • Cloudscape-Weblogic XA mismatch

    Hello,
    First, yes I know Cloudscape may not be the best database for production and
    XA, but anyway, I have to use it, and it supports XA.
    Now my question :
    I'm using WLS 6.1 SP1.
    I defined a Cloudscape XA pool which seems to initialize well (the server
    logs shows initial connections creations for the XA pool successfully). For
    this pool, the driver classname I use is COM.cloudscape.core.XADataSource.
    Over this pool I defined a Tx Data Source which some JNDI name, let's say
    "MyXADataSource".
    This works well and I can get and use connections from this "MyXADataSource"
    datasource while I use it as a javax.sql.DataSource (from a BMP for
    example).
    However this DataSource is not XA. I mean that it does not implement
    javax.sql.XADataSource (the concrete class is actually
    weblogic.jdbc.common.internal.RmiDataSource). This is a problem for example
    when a connector (let's say the BlackBoxXA sample connector) tries to use
    this datasource as an XA datasource, leading to a ClassCastException.
    So why the concrete weblogic.jdbc.common.internal.RmiDataSource class is not
    an XA class ? Did I configure something wrong or forget something ?
    Thanks for your help.
    Jérôme.

    Hello Slava,
    Thank for your reply.
    However as I said, this remains a problem when the BlackBoxXA connector
    tries to use this datasource as an XA datasource, because its implementation
    does an explicit cast to XADataSource (leading to a ClassCastException).

    Hi,
    When you lookup for a datasource, you get an object
    implementing DataSource interface, not XADataSource.
    You don't have to cast it to XADataSource. If you need
    XA behavior, all you need is setting up a TXDataSource
    with a driver implementing XADataSource. weblogic will
    take care about the rest.

  • Cloudscape not jdbc compliant?

    I was just checking out Cloudscape (the DBMS that comes with j2sdkee) and noticed that when I run a DriverManager.jdbcCompliant() after registering the cloudscape driver with the manager - it returns false.
    Does anyone know why that is?
    -d|w

    Just as a follow-up, this is the answer that I received when posting my question to the cloudscape dev list:
    JDBC compliance requires full support for the JDBC API and full support for SQL
    92 Entry Level.
    Cloudscape compliance for these specifications is documented in the Release
    notes under "Cloudscape and Standards " and in more detail in Chapter 6 of the
    Cloudscape Reference manual "JDBC Reference". Some examples of non-compliance
    documented for version 5.0 are:
    - Cloudscape does not use catalog names
    - Cloudscape 5.0 only supports:
    java.sql.Connection.TRANSACTION_SERIALIZABLE,
    java.sql.Connection.TRANSACTION_REPEATABLE_READ, and
    java.sql.Connection.TRANSACTION_READ_COMMITTED

  • Beginner: some questions

    Hello all,
    I am just a beginner for EJB, and writing a simple example of EJB. Some questions confuse me.
    1.     about server
    I just use JDK1.3.1 and JSDKEE1.3, is it all right? Do I need another things, for instance, weblogic ( what is this?)?
    2.     about deployment
    I wrote some code( CMP) include: home interface, remote interface, implement class, and primary key. Now , deploy it? Use ��C:\j2sdkee1.3\bin\deploytool�� command, is it?
    I thought every EJB need a XML deployment descriptor, my question is: I write this by myself or use deploytool?
    3.     about datebase
    I notice some example use Cloudscape, is this database? Whether can I use another database, for instance, MS Access? If I can, how to access it in CMP, and what is the ��Database JNDI Name��( if I use MS Access) when I deploy using deploytool?
    4.     about direction
    if I finish coding, then compile, and deploy, now, is it OK? I mean, I should move some file to special direction? (I remember the .class file is placed in special direction when I use servlets. )(suppose: I work in C:\mybean. Every file in it)
    5.     I use JDK1.3.1 and JSDKEE1.3 to write a simple example, do I need anything else in order to achieve EJB?
    Thanks

    1. No you do not need anything other than J2SE 1.3.1 and J2EE SDK 1.3 J2EE SDK 1.3 includes a reference implementation that you can use to do pretty much everything that is J2EE platform standard.
    Products such as WebLogic, WebSphere are comercial implementations of J2EE platform specifications. And you would use them for commercial/production quality applications.
    See http://java.sun.com/j2ee/faq.html Especially the questions about using reference implementation.
    2. You as a developer write the deployment descriptor and the deployment engineer customizes it if required at deployment time.
    3. You can use JDBC-ODB driver to work with Microsoft Access databse.
    See http://java.sun.com/j2se/1.3/docs/guide/jdbc/getstart/bridge.doc.html#996747
    4. No. The files go to the right place at deploy time.
    5. No. If you have J2SE 1.3.1 and J2EE SDK 1.3, you arealready on your way to achieving EJBs.

  • Cloudscape 10,0

    Does cloudscape 10.0 support data compression

    The best place for cloudscape/derby questions is the derby mailinglist from the derby project on incubator.apache.org.
    I am not quite sure what you are looking for, but derby/cloudscape support blob data types so u could certainly store something that is compressed yourself.

  • Questions on Print Quote report

    Hi,
    I'm fairly new to Oracle Quoting and trying to get familiar with it. I have a few questions and would appreciate if anyone answers them
    1) We have a requirement to customize the Print Quote report. I searched these forums and found that this report can be defined either as a XML Publisher report or an Oracle Reports report depending on a profile option. Can you please let me know what the name of the profile option is?
    2) When I select the 'Print Quote' option from the Actions drop down in the quoting page and click Submit I get the report printed and see the following URL in my browser.

    Does it mean that the profile in our case is set to call the rdf since it has reference to ASOPQTEL.rdf in the above url?
    3) When you click on submit button do we have something like this in the jsp code: On click call ASOPQTEL.rdf. Is the report called using a concurrent program? I want to know how the report is getting invoked?
    4) If we want to customize the jsp pages can you please let me know the steps involved in making the customizations and testing them.
    Thanks and Appreciate your patience

  • Satellite P300D-10v - Question about warranty

    HI EVERYBODY
    I have these overheating problems with my laptop Satellite P300D-10v.
    I did everything I could do to fix it without any success..
    I get the latest update of the bios from Toshiba. I cleaned my lap with compressed air first and then disassembled it all and cleaned it better.(it was really clean insight though...)
    BUT unfortunately the problem still exists...
    So i made a research on the internet and I found out that most of Toshiba owners have the same exactly problem with their laptop.
    Well i guess this is a Toshiba bug for many years now.
    Its a really nice lap, cool sound (the best in laptop ever) BUT......
    So I wanted to make a question. As i am still under warranty, can i return this laptop and get my money back or change it with a different one????
    If any body knows PLS let me know.
    chears
    Thanks in advance

    Hi
    I have already found you other threads.
    Regarding the warranty question;
    If there is something wrong with the hardware then the ASP in your country should be able to help you.
    The warranty should cover every reparation or replacement.
    But I read that you have disasembled the laptop at your own hand... hmmm if you have disasembled the notebook then your warrany is not valid anymore :(
    I think this should be clear for you that you can lose the warrany if you disasemble the laptop!
    By the way: you have to speak with the notebook dealer where you have purchased this notebook if you want to return the notebook
    The Toshiba ASP can repair and fix the notebook but you will not get money from ASP.

    i was messing around and came up with this. it doesnt remove the null, but if it is null it adds ABC beside it. so i think i might be getting close. i just need to figure out how to replace the null.

         <% if (request.getParameter("steptwoFour") == null ) {

  • Anyone know how to remove Overdrive books from my iphone that have been transferred from my computer? They do not show up on itunes. I see a lot of answers to this question but they all are based on being able to see the books in iTunes.

    How do I remove Overdrive books from the library that were downloaded onto my computer then transferred to my iphone? The problem is that they do not show up in iTunes.
    I see this question asked a lot when I google, but they always give answers that assumes you can find the books in iTunes either under the books tab, or the audio books tab or in the music. They do not show up anywhere for me. They do not remove from the app like the ones I downloaded directly onto my iphone.the related archived article does not answer it either.  I even asked a guy working at an apple store and he could not help either.   Anybody...?
    Thanks!

    there is an app called daisydisk on mac app store which will help you see exactly where the memory is focused and consumed try using that app and see which folders are using more memory

  • Basic question

    Hello, i have a basic question. if i have defined 2 fields in a cube or a dso:
    Name Quantity
    and from the external flat file i get some characters for my quantity field. would my load fail?  for standard dso and for write optimized?
    NOTE: quantity field is a keyfigure defined as numeric.
    and the load coming in has "VIKPATEL" for Quantity field and not numbers.
    thanks

    Hi Vik,
    Yes, the load will fail.
    May be you coud first load this data into BW (into PSA) and set both fields as characters fields. Then you can create DSO, do transformation from this PSA to the DSO, and put your logic as to what do you want to do with those Quantity that is not number (e.g. convert to 0, or 'Not assgined', etc).
    You can use transfer rule, or a clean up ABAP code in the start routine.
    Hope this helps.

  • Mid 2010 15" i5 Battery Calibration Questions

    Hi, I have a mid 2010 15" MacBook Pro 2.4GHz i5.
    Question 1: I didn't calibrate my battery when I first got my MacBook Pro (it didn't say in the manual that I had to). I've had it for about a month and am doing a calibration today, is that okay? I hope I haven't damaged my battery? The calibration is only to help the battery meter provide an accurate reading of how much life it has remaining, right?
    Question 2: After reading Apple's calibration guide, I decided to set the MacBook Pro to never go to sleep (in Energy Saver System Preference) and leave it on overnight so it would run out of power and go to sleep, then I'd leave it in that state for at least 5 hours before charging it. When I woke up, the light on the front wasn't illuminated. It usually pulsates when in Sleep. Expectedly, it wouldn't wake when pressing buttons on the keyboard. So, what's happened? Is this Safe Sleep? I didn't see any "Your Mac is on reserve battery and will shut down" dialogues or anything similar, as I was asleep! I've left it in this state while I'm at work and will charge it this afternoon. Was my described method okay for calibration or should I have done something different?
    Question 3: Does it matter how quickly you drain your battery when doing a calibration? i.e is it okay to drain it quickly (by running HD video, Photo Booth with effects etc) or slowly (by leaving it idle or running light apps)?
    Thanks.

    Fresh J:
    A1. You're fine calibrating the battery now. You might have gotten more accurate readings during the first month if you'd done it sooner, but no harm has been done.
    A2. Your machine has NOT shut down; it has done exactly what it was supposed to do. When the power became critically low, it first wrote the contents of RAM to the hard drive, then went to sleep. When the battery was completely drained some time later, the MBP went into hibernation and the slepp light stopped pulsing and turned off. In that state the machine was using no power at all, but the contents of your RAM were still saved. Once the AC adapter was connected, a press of the power button would cause those contents to be reloaded, and the machine would pick up again exactly where you left off. It is not necessary to wait for the battery to be fully charged before using the machine on AC power, but do leave the AC adapter connected for at least two hours after the battery is fully charged. Nothing that you say you've done was wrong, and nothing that you say has happened was wrong.
    A3. No, it does not matter.

  • Jabber/WebEx Connect SSO Questions

    I've got a few questions around exactly what needs to be done to get SAML working for our Connect accounts to successfully authenticate from Jabber for Windows, Mac, iPhone, and Android.
    We have both a Meeting Center and Connect account under WebEx using Loose Coupled Integration. Just this past week I enabled SAML for our Meeting Center accounts which went off without a hitch with the exception of Meeting Center integration with Jabber, which is now broken with a message about SSO enabled Meeting Sites not being supported (I think this would maybe be fixed if we had Tight Coupled Integration with our two account?).
    Anyway, my questions are...
    For Windows, I understand all clients will need to be reinstalled with the MSI argument for the SSO_ORG_DOMAIN switch I've read about, is that correct? Are there any other switches needed for the reinstall? 
    How will this work with the Mac and mobile clients? There's obviously no command line options to specify for the installations here, will they just know to kick over to my IdP for authentication once they see an email address that falls under an org with SSO enabled? If so, why does the Windows client need to be completely reinstalled and not just know to find the IdP from the Cloud Connect service like Meeting Center does with the Productivity Tools?
    We're just doing this for our Connect Web IM accounts, not attempting any sort of SSO with the phone accounts/UC integration yet.
    Any ideas on getting the Meeting Center integration into Jabber working again?

    I'd suggest posting your question over on the Jabber Pilot forum, as this forum is specific to Jabber Guest questions:
