Enum from C/C++ in java?

This is really a question for people who have used C/C++ and now use Java. Is there anything like the enum from the C/C++ language in Java? I would really like to use something like this, but as far as I can tell there is no way to create an enumeration of identifiers even by trying something like #define (any Java equivilent?). The best I can think of is create a class of 'properties' that have a bunch staticly defined variables.
-- Deep_T

Here's what I've done in the past for typseafe enums:
public class Color{
public static final Color RED=new Color();
public static final Color GREEN=new Color();
}There may be better ways to do it...I think the standard idiom is to have a private constructor that takes a string. This way a) you can't add new elements at runtime (though maybe in some cases you want to?) and b) you can have a meaningful toString() method.

  • Pasting Image  from Mac clipboard to Java Based Application.

    Hi,
    I am working on "iMac 10.2.7". I need to paste an image from other
    application using "Java version 1.4.1". I am trying to retrieve the image
    from the system clipboard after it is copied from some other application. I
    am pasting the code which illustrates my requirement. It works fine on
    windows. But does not work on Mac.
    On Mac it does not cross the supported data flavor check
    (clipData.isDataFlavorSupported(DataFlavor.imageFlavor) where clipData is
    the Transferable object). It seems Mac has some InputStream instead of Image
    in the clipboard when some image is copied. I tried to read that InputStream
    using ImageIO.read(java.io.InputStream). But that is also returning null.
    Thanks

    Can anyone let me know where is the problem?

    Actually, the question boils down to; does the framework support the fonts?
    I believe that my question re. this working in the designer was valid. The designer does not use the framework, so if it works there, it is either a framework issue or a runtime print engine issue.
    I believe if you use the code below, it will list fonts available to the framework:
    foreach(FontFamily ff in FontFamily.Families)
    System.Diagnostics.Debug.WriteLine(ff.Name);
    For more information see kbase [1198306 - Crystal Report displaying incorrect font in Microsoft Visual Studio .NET|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_dev/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333133393338333333303336%7D.do]

  • How can i pass string from C++ DLL to Java via JNI?

    Hi everybody. I made a DLL with Borland C++. I must pass a string from this dll to Java via JNI.Namely i define a string variable in C++ DLL and i send this variable's value to Java via JNI.
    I can pass integers but i couldnt Strings. . How can i do this? is there any sample?

    Hi,
    So your function should be private static native String get_text();
    (It's often a good idea to make native methods private since when you change signatures you generally have to change java wrapper methods only).
    I know nothing about C++ strings but I'm pretty sure that you can convert it to char*, so
    do :
    char* szMyString = myString.toChar*();
    Then return from native with JNU_NewStringPlatform(env, szMyString)
    (see my 1st answer for JNU_NewStringPlatform() description).
    --Marc (http://jnative.sf.net)

  • Retrieval of xmltype data from oracle 10g to java

    Hi
    Right now we are facing an issue on xmltype retrieval from oracle 10g to java.
    I used xmltype column.getClobval() to get the xml content, but unable to do the parse to get the xml data.
    So i tried getStringval(), getting the xml content as string format and here in this case also, i didn't get document object.
    Here is the code snippet:
    String sql = "SELECT node_id,node_desc,parent_node_id,e.report_xml.getStringval() FROM TABLE_STRUCTURE e";
    st = con.createStatement();
    rs = st.executeQuery(sql);
    while (rs.next()) {
    Object value[] = { rs.getString(1), rs.getString(2), rs.getString(3), rs.getString(4) };
    list.add(value);
    DOMParser parser = new DOMParser();
    parser.parse(rs.getString(4));
    doc = (Document) parser.getDocument();

    Hello,
    In Firefox 23, as part of an effort to simplify the Firefox options set and protect users from unintentially damaging their Firefox, the option to disable JavaScript was removed from the Firefox Options window.
    However, the option to disable JavaScript was not removed from Firefox entirely. You can still access it from about:config or by installing an add-on.
    '''about:config'''
    # In the address bar, type "about:config" (with no quotes), and press Enter.
    # Click "I'll be careful, I promise"
    # In the search bar, search for "javascript.enabled" (with no quotes).
    # Right click the result named "javascript.enabled" and click "Toggle". JavaScript is now disabled.
    To Re-enable JavaScript, repeat these steps.
    '''Add-ons'''
    You can alternatively install an add-on that lets you disable JavaScript, such as
    *[https://addons.mozilla.org/firefox/addon/noscript/ No-Script] (to disable JavaScript on a per page basis, as required)
    *[https://addons.mozilla.org/firefox/addon/quickjava/ QuickJava] (to easily disable and enable JavaScript, automatic loading of images, and other content)
    Thank you and I hope this helps!

    Hello,
    Can anybody tell me where i can find the latest JAVAAPI reference guide? I found the one for MDM 5.5 SP 1 but that also refers to the last parameter of the CatalogCache.Init as int and not string.
    I looked up in service.sap.com/instguides -> SAP Netweaver -> Release 4 -> Installation and there only following 3 files are there for MDM 5.5 SP2
    MDM 5.5 SP02 - Configuration Guide  SAP MDM
    MDM 5.5 SP02 - Installation Guide   SAP MDM

    again
    get
    can't exec: /tmp/sri/GROUP_ho.sh lacks user privilege
    same error;

    Process management at the OS level should prevent execution continuing in the calling code until the command has completed (either successfully or with error).
    If the low level java code were to spawn child process threads then execution could continue, but I'm guessing the Java function your talking about doesn't do that and just calls the operating system to execute the command and waits for the returning code to come back.

  • Capturing Print Statements from Oracle SP in Java

    Hi all,
    Greetings...
    I have one query...pls find below the info for the same:
    From my Java application, i am calling Oracle SP using Callable Statement.
    Here is the simple Oracle SP..
    01. CREATE OR REPLACE PROCEDURE TEST_ORACLE(errcode OUT
    02. NUMBER, errdesc OUT CHAR)
    03. AS
    04. BEGIN
    05. dbms_output.put_line('Start of the SP');
    06. // SQL Statements will come here
    07. dbms_output.put_line('End of the SP');
    08. END TEST_ORACLE;
    In Line (5) and (7), I have given Print Statements (SOP statements). I need to capture those SOP messages from Java while executing SP / after exceuting it.
    In the Java application, i tried the following:
    callableStatement.execute();
    SQLWarning warnings = callableStmt.getWarnings();
    while(warnings != null)
    if(warnings.getErrorCode() == 0 && warnings.getSQLState() == null)
    System.out.println("Print Statements From SP: "
    + warnings.getMessage() );
    warnings = warnings .getNextWarning();
    Here warning object is null and i am unable to capture those print statements.
    How to capture those print statements from Oracle SP in Java ?
    Thanks in advance..

    Try writing them to a file and read them from your program.
