How to pass -Hotspot or -Xingc to the jvm when using an executable Jar?

Hi, my problem is that when i start my application with the jar-File ("Main-Class: " in the Manifest), it 's very slow.
When i start it with
java -hotspot -Xincgcit works fine.
So my question is: how do I have to set these options in the Manifest of the Jar-File?
Thanks a lot in advance.
Michael

So my question is: how do I have to set these options in the Manifest of the Jar-File?You don't.
An executable jar supplies information on running it to whatever runs it. The parameters "-hotspot -Xincgc" are parameters to a specific jvm and as such belong to the jvm not the jar.
If you want your stuff to run with that then do one of the following:
-Provide an install that sets the computer up that way.
-Provide a script for each OS that you support that runs it with the required options (forget the executable jar.)

  • How to pass username and password with the portal url

    i want to access portal from my web site. i have created username and password fields in my web page. when submited , my portal page should open. so how to pass username and password with the portal url.

    This is not straightforward; but it is doable.
    First tell us about your portal version; portal 10.1.4 has a slightly different method of doing it and the pre-10g portals were completely different animals.
    And if you are in AS Rel 2, then the most important document for you would probably be the following:
    [Creating Deployment Specific Pages| http://download-west.oracle.com/docs/cd/B14099_19/idmanage.1012/b14078/custom.htm#i1015535]
    You might want to use it in conjunction with some metalink notes about your portal version and such a login page.
    hope that helps!

  • How to pass a xml CDATA in string element when OSB calling a webservice?

    How to pass a xml CDATA in string element when OSB calling a webservice?
    I have a business service (biz) that route to operation of a webservice.
    A example of request to this webservice legacy:
    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:eg="example">
    <soapenv:Header/>
    <soapenv:Body>
    <ex:execute>
    <ex:arg><![CDATA[<searchCustomerByDocumentNumber>
    <documentNumber>12345678909</documentNumber>
    </searchCustomerByDocumentNumber>]]></ex:arg>
    </ex:execute>
    </soapenv:Body>
    </soapenv:Envelope>
    the type of ex:arg is a string.
    How to pass this CDATA structure to webservice in OSB?

    Steps to solve this problem:
    1. Create a XML Schema. E.g.:
    <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
         elementFormDefault="unqualified">
         <xs:complexType name="searchCustomerByDocumentNumber">
              <xs:sequence>
                   <xs:element name="documentNumber" minOccurs="0">
                        <xs:annotation>
                             <xs:documentation>
                             </xs:documentation>
                        </xs:annotation>
                        <xs:simpleType>
                             <xs:restriction base="xs:string" />
                        </xs:simpleType>
                   </xs:element>
         </xs:sequence>
         </xs:complexType>
         <xs:element name="searchCustomerByDocumentNumber" type="searchCustomerByDocumentNumber"></xs:element>
    </xs:schema>
    With this XSD, the XML can be generate:
    <?xml version="1.0" encoding="UTF-8"?>
    <searchCustomerByDocumentNumber xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="searchCustomerByDocumentNumber.xsd">
    <documentNumber>documentNumber</documentNumber>
    </searchCustomerByDocumentNumber>
    2. Create a XQuery to create a searchCustomerByDocumentNumber ComplexType. E.g.:
    (:: pragma bea:global-element-return element="searchCustomerByDocumentNumber" location="searchCustomerByDocumentNumber.xsd" ::)
    declare namespace xf = "http://tempuri.org/NovoSia/CreateSearchCustomerByDocumentNumber/";
    declare function xf:CreateSearchCustomerByDocumentNumber($documentNumber as xs:string)
    as element(searchCustomerByDocumentNumber) {
    <searchCustomerByDocumentNumber>
    <documentNumber>{ $documentNumber }</documentNumber>
    </searchCustomerByDocumentNumber>
    declare variable $documentNumber as xs:string external;
    xf:CreateSearchCustomerByDocumentNumber($documentNumber)
    3. In your stage in pipeline proxy add a assign calling the XQuery created passing the document number of your payload.
    Assign to a variable (e.g.: called searchCustomerByDocumentNumberRequest)
    4. Create another XQuery Transformation (XQ) to create a request to the webservice legacy. E.g.:
    <ex:arg>{fn-bea:serialize($searchCustomerByDocumentNumberRequest)}</ex:arg>
    For more information about xquery serialize function:
    41.2.6 fn-bea:serialize()
    You can use the fn-bea:serialize() function if you need to represent an XML document as a string instead of as an XML element. For example, you may want to exchange an XML document through an EJB interface and the EJB method takes String as argument. The function has the following signature:
    fn-bea:serialize($input as item()) as xs:string
    Source: http://docs.oracle.com/cd/E14571_01/doc.1111/e15867/xquery.htm

  • How do I find, at-a-glance, the sample size used in several music files?

    How do I find, at-a-glance, the sample size used in several music files?
    Of all the fields available in a FInder Search, "Sample Size" is not available. Finder does offer a "Bits per Sample" field, but it only recognized graphic files and not music files.
    Running 10.8.5 on an iMac i5.
    I did search through a couple of communities but came up empty.
    Thank you,
    Craig

    C-squared,
    There is no View Option to allow display of a column of sample size. 
    For WAV or Apple Lossless files, it is available on the Summary tab (one song at a time, as you know).  For MP3 and AAC it is not available at all.
    You can roughly infer it from the files that are larger than expected for their time.
    99% of the music we use is at the CD standard of 16-bit, so I can guess that displaying it has never been a priority.  However, if you want to make a suggestion to Apple, use this link:

    First, go to iMovie/Preferences and enable the Advanced Tools.
    Import the video clip into an iMovie Event. When you get ready to use it in an iMovie Project, select the clip in the Event and drag & drop it on top of a video or photo clip in the project at the place where you want it to begin. When the pop-up menu appears, choose Audio Only.

  • How to find out which type of the driver is used in our application?

    Hi all,
    can anyone tell me how to find out which type of the driver is used in our application?
    Thanks in advance,
    Phoeniox

    Hi,
    Check out this...
    Class.forName("com.mysql.jdbc.Driver"); //if u r using MySql
    List drivers = Collections.list(DriverManager.getDrivers());
                   for(int i=0;i<drivers.size();i++)
                        Driver driver = (Driver)drivers.get(i);
                        String driverName = driver.getClass().getName();
                        System.out.println("Driver "+i+":::"+driverName);
    you need to load the driver and display in the same program.
    Then only you'l get the required result.

  • How can I force mount a dvd that isn't even seen by Disk Utility? I can see it on the Mac when using my Windows 7 partition via Boot Camp, but not in Lion, which is how I would rather be running.

    How can I force mount a dvd that isn't even seen by Disk Utility? I can see it on the Mac when using my Windows 7 partition via Boot Camp, but not in Lion, which is how I would rather be running.

    Well if there is a EFI block, then running a program in OS X isn't going to do a lick of good.
    After all EFI was designed for Trusted Computing and Digital Rights Management, to act between the OS and hardware, can read drives, contact the Internet and everything.
    Windows doesn't use EFI, will have UEFI in Windows 8 though.

  • How can I determine what dns server the wifi client use within airport

    How can I determine what dns server the wifi client use within airport
    I want to use dns servers other then the one that airport extreme is using. For example I got the 172.16.1.1 (the default gateway - airport extreme), but I want to use the office dns servers, that are in a 10.x.x.x range.
    Is there a possibility?
    Thanks and happy eastern

    The Airport Extreme uses the DNS servers assigned by the network that it connects to. Is you Airport Extreme on the 10.x.x.x network? if it is then you are already using the 10.x.x.x DNS servers. Check your Airport Extreme with the Airport Utility and you will see in the Internet tab, the DNS servers used. The devices connecting to the Airport Extreme are assigned a DNS address of the Airport Extremes IP, In your case 172.16.1.1 but all DNS searches and resolution are done with the DNS servers you see in the Airport Extreme.
    If you want to use some other DNS then you can override in the Airport Extreme which will be used by all devices connecting too the Airport Extreme, Or you can edit the DNS address in each devices wireless settings.

    BUT the image didn't actually work and all I ended up with was the word JPEG and a generic image... Any assistance would be appreciated - Thank you.
    Sounds like you copied an icon from the icon spot in a Get Info window for an image file, then pasted that intoo the same spot in the Get Info window for your folder. As you found out, that won't work - unless the image file already has a custom icon, that is.
    Visually, it's hard to tell if an image file has a custom icon, particularly if View Options for a folder (or the desktop) has been set to 'show icon preview' - the OS will use Preview to make an icon for that file 'on the fly', but it does not really exist as far as being a copyable icon.
    For what you want to do, the solution is really very easy.
    Do a Get Info on the image file whose icon you want to copy for your folder. In that Get Info window is a larger depiction of the image about halfway down - double-click that, and it should open in Preview.
    Press Command-A (that's Select All in the Edit menu).
    Press Command-C (that's Copy in the Edit menu).
    Close Preview, close the Get Info window for the image file.
    Open the Get Info window for your folder.
    Select the icon in the upper left by clicking it once - a blue border should appear around it.
    Press Command-V (that's Paste in the Edit menu).
    Close the Get Info window, and you're done.
    Comment - that's a nice way to make unique folder icons, but there is one drawback: how to distinguish visually between a folder with such an icon and an image file.
    One way, old school, is to append the character ƒ to the end of the name you give the folder. That character is easily generated by pressing Option-F and can be a visual indicator that the item is actually a folder and not an image.

    how can i reload font information while the jvm is running.
    I'm having the following problem...
    A program is running.
    A user installs a new font on the system (Xwindows in this case)
    Java doesn't display the font when i ask :
    java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();Thus i think that java buffers its font information somewhere. Anyone knows how to refresh te buffer?

  • How can I customize the toolbar when using the attribute browser

    In CVI 2012, the toolbar changes depending on the environment, e.g. it is different for the source window and the UI editor. The toolbar can be customized using the menu Options / Toolbar...
    Unfortunately, when using the attribute browser of the UI editor, another toolbar is displayed, i.e. not the UI editor toolbar.... I would have assumed that the attribute browser belongs to the UI editor, obviously it doesn't... So how can I customize the toolbar when using the attribute browser?
    Solved!
    Go to Solution.

    Luis,
    It's nice to have you back 
    Thank you for the clarification, so I'll elaborate a bit more: In the regular workspace toolbar, I have a disk symbol to save the file. This symbol is gone in the attribute browser...
    So I have three different toolbars, for source code (workspace), UI editor, and the UI editor displayed but the attribute browser clicked on (selected)... 
    Thanks
