EM Empty in webbrowser

Hello, i'm new in the oracle world. So maybe i have strange question. When i install the latest version of oracle (10g) all seems to work fine. Then i go to browser and try to login with sys or other login name. All seems to go well. But as i understand i must get a screen where i can do some works like adding users. But the screen remain empty i see nothing only the login screen remain. I try names like sysman, sys system etc.
I thougt i must get screen where i can add users to database. I hope that someone can help me out here.. thanks.

After initial install, log in as the sysman user using the password you provided during the EM install. If it returns you to the log on screen there should be a message indicating logon failure.
When successfully logged in you will see something that looks quite similiar to the metalink.oracle.com page, with tabs, etc.

  • [BUG?] af:table table empty after descending sort and remove

    Hi,
    I think i found a bug.
    I have an af:table binded to an arraylist in a backingbean. This List consist of an object that represents two strings (value 1 and 2).
    Now when the table is loaded and I sort descending on one of the columns. After sorting i'll try to remove a row. The correct row is published to the bean with an af:setPropertyListener and removed from the arraylist. But when the table is rendered again there are no values in the table. But the arraylist still has all remaining values which will be shown after a sort again.
    Fun fact: it only happens when sorting descending.
    Anyone got an idea?

    Hi Harry (and others),
    I have seen similar behavior. It seems like the client side rendering for some reason has a hard time processing the collection model wrapping the ArrayList in this particular case. The table renders empty. After sorting in ascending order, the rows are all back (visible) again.
    Is anyone aware of issues with the rich table based directly on ArrayList (in combination with a changing set of values and/or sorting)? (seems like a corner case but is still not uncommon). Is there any indication that wrapping the ArrayList in a CollectionModel ourselves might be required?
    Harry: do you know whether this issue is introduced with PS3 (11.1.1.4) or already existed in previous releases?
    kind regards,
    Lucas

    in my VC project, webPage.CallJScript(_T("FuncMain")) succeeded!
    webPage.CallJScript(_T("page_test2.showAlert") failed,  the GetIDsOfNames() return DISP_E_UNKNOWNNAME. BTW, webPage.CallJScript(_T("showAlert")
    also failed! Same error.
    any help?

    Thanks for your reply Viorel_.
    i know i can define a function in the main page: 
    function showAlert_Main(x)
            document.frames('page_test2').showAlert(x);
    then, webPage.CallJScript(_T("showAlert_Main"))
    succeeds.
    but this function is just an empty shell doing nothing, and i know there must have a way to call showAlert(x) directly.

  • Cannot assign an empty string to a parameter with JDBC type VARCHAR

    Hi,

    Heres the complete detail from logs -

  • Oracle, Null and empty Strings

    Currently I'm facing problems with a class, which contains a String, which
    is set to "" (empty String).
    When the class is persistent, oracle writes null to the table column
    (which seems to be common oracle behaviour) and when retrieving the class,
    the field is set to null as well, giving me a lot of null-pointer
    exceptions.
    Anyway ... I can cope with that (just a lot of extra work)
    far worse is the problem, wenn searching objects, that have this field set
    to "" oder null.
    Oracle can't find the records because JDO creates Querys "where
    string=null" or "where string=''" , where oracle expects "where string is
    null" to find the records.
    Is there a workaround or solution ?

    Yeah, that would work as well, thx, but since I have to cope with
    null-Strings now everywhere in my program, it doesn't hurt just to forbid
    empty strings on the program side.
    In future times I'll test on Oracle first, then porting to DB/2 - this way
    I suppose work is far less to garant compability.
    Nevertheless ... having to set the bankcode into quotes is a kodo bug in
    my opinion.
    Kodo knows the type of classfields (in this case string) and shouldn't
    send the parameter as a BigDecimal to the database.
    Given that, and having only bankcodes of null (only neccesary when using
    Oracle), the method would look like:
    public Collection getAccounts (String bankCode)
    throws Exception
    return getAccounts (Account.class, "bankcode=="+bankcode);
    which is how a transparent persistent layer, um, should be , um , I mean
    ... just transparent ;-D

    Stefan-
    Couldn't you just do something like:
    public Collection getAccounts (String bankCode)
    throws Exception
    String filter;
    if (bankCode == null || bankCode.length () == 0)
    filter = "(bankCode == null || bankCode == "")";
    else
    filter = "bankCode == "" + bankCode + """;
    return getAccounts (Account.class, filter);
    If I understand the problem correctly, this should work for all the
    databases.

    What operations are you performing to cause this SQL to be issued? You

    A string column... is it also represented as a string field in your class?Yeah ... just to give you an impression of the code:
    First we have a class, representing a bank account:
    public class Account {
    private AccountMgr myAccountMgr;
    private String bankCode;
    private String id;
    Note, that in nearly all cases bankCode will be a number or null.
    I have a second class "AccountMgr", which does all of the persistant stuff
    (seaching, making persistent etc.)
    This class has two methods, one versatile (protected) to retrieve accounts
    by a given filterString and one who just returns accounts by bankCode,
    building the expected filterstring. Here is my current working version:
    public class AccountMgr {
    public Collection getAccounts(String bankCode) throws Exception {
    if (bankCode!=null) {
    if (bankCode.equals("")) {
    throw new Exception("check code, bankCode='' not allowed to get
    same behavior from DB2 and Oracle");
    // if set, quote the bankCode
    bankCode="""+bankCode+""";
    return getAccounts(Account.class,"bankCode=="+bankCode);
    protected Collection getAccounts(Class accountClass, String filterAdd)
    throws Exception {
    PersistenceManager pm = MyHelper.getPersistenceManager();
    String filter="";
    if (filterAdd!=null && !filterAdd.trim().equals("")) {
    filter+=filterAdd + " && ";
    filter += "myAccountMgr==_accMgr";
    Query query = pm.newQuery(accountClass, filter);
    query.declareParameters("AccountMgr _accMgr");
    return (Collection) query.execute(this);
    As you can see, in the first method I have to set the bankCode into
    quotes, when it's not null.
    This is because otherwise a filter like "bankCode=1234" will be translated
    in a way, where 1234 is send as a BigDecimal to the database:
    [...] executing statement <4239745>: (SELECT [...] FROM JDO_ACCOUNT t0
    WHERE t0.BANKCODE = ? : [reused=1;params={(BigDecimal) 1234}]

  • NULL and Empty String

    Hi There,
    As far as I know, Null is not the same as an empty string; however, when I try this out, I get some unexpected results (well, at least unexpected for my liking):
    SQL> CREATE TABLE TS (MID NUMBER,
      2  MDESC VARCHAR2(20) DEFAULT '' NOT NULL);
    Table created.
    SQL> INSERT INTO TS VALUES(1,'');
    INSERT INTO TS VALUES(1,'')
    ERROR at line 1:
    ORA-01400: cannot insert NULL into ("TT"."TS"."MDESC")So, according to the above scenario, I can't insert an empty string!! However, an empty string is a valid string that doesn't have tuples/data!!
    How come Oracle translates the null string '' as NULL?
    Thanks

  • Null and empty string not being the same in object?

    Hello,
    I know that null and empty string are interpreted the same in oracle.
    However I discovered the strange behaviour concerning user defined objects:
    create or replace
    TYPE object AS OBJECT (
    value VARCHAR2(2000)
    declare
    xml xmltype;
    obj object;
    begin
    obj := object('abcd');
    xml := xmltype(obj);
    dbms_output.put_line(xml.getStringVal());
    obj.value := '';
    xml := xmltype(obj);
    dbms_output.put_line(xml.getStringVal());
    obj.value := null;
    xml := xmltype(obj);
    dbms_output.put_line(xml.getStringVal());
    end;
    When creating xml from object, all not-null fields are transformed into xml tag.
    I supposed that obj.value being either '' or null will lead to the same result.
    However this is output from Oracle 9i:
    <OBJECT_ID><VALUE>abcd</VALUE></OBJECT_ID>
    <OBJECT_ID><VALUE></VALUE></OBJECT_ID>
    <OBJECT_ID/>
    Oracle 10g behaves as expected:
    <OBJECT><VALUE>abcd</VALUE></OBJECT>
    <OBJECT/>
    <OBJECT/>
    However Oracle 9i behaviour leads me to the conclusion that oracle
    must somehow distinguish between empty string and null in user defined objects...
    Can someone clarify this behaviour?
    Thus is it possible to test if object's field is empty or null?

    Thus is it possible to test if object's field is empty or null?A lot of "fixes" were done, relating to XML in 10g and the XML functionality of 9i was known to be buggy.
    I think you can safely assume that null and empty strings are treated the same by Oracle regardless. If you're using anything less than 10g, it's not supported any more anyway, so upgrade. Don't rely on any assumptions that may appear due to bugs.

  • Difference in Null and Empty String

    Hi,
    I have been wondering about the difference between Null and Empty String in Java. So I wrote a small program like this:
    public class CompareEmptyAndNullString {
         public static void main(String args[]) {
              String sNull = null;
              String sEmpty = "";
              try {
                   if (sNull.equalsIgnoreCase(sEmpty)) {
                        System.out.println("Null and Empty Strings are Equal");
                   } else {
                        System.out.println("Null and Empty Strings are Equal");
              } catch (Exception e) {
                   e.printStackTrace();
    This program throws Exception: java.lang.NullPointerException
         at practice.programs.CompareEmptyAndNullString.main(CompareEmptyAndNullString.java:10)
    Now if I change the IF Clause to if (sEmpty.equalsIgnoreCase(sNull)) then the Program outputs this: Null and Empty Strings are Equal
    Can anyone explain why this would happen ?
    Thanks in Advance !!

    Saish,
    Whether you do any of the following code, the JUnit Test always passes: I mean he NOT Sign doesnt make a difference ...
    assert (! "".equals(null));
    assert ("".equals(null));
    You probably have assertions turned off. Note the the assert keyword has nothing to do with JUnit tests.
    I think that older versions of JUnit, before assert was a language keyword (which started in 1.4 or 1.5), had a method called assert. Thus, if you have old-style JUnit tests, they might still compile, but the behavior is completely different from what it was in JUnit, and has nothing to do with JUnit at all.
    If you turn assertions on (-ea flag in the JVM command line, I think), the second one will throw AssertionError.

  • Check for null and empty - Arraylist

    Hello all,
    Can anyone tell me the best procedure to check for null and empty for an arraylist in a jsp using JSTL. I'm trying something like this;
    <c:if test="${!empty sampleList}">
    </c:if>
    Help is greatly appreciated.
    Thanks,
    Greeshma...

    A null check might not be you best option.  If your requirement is you must have both the date and time component supplied in order to populate EventDate, then I would use a Script Functoid that takes data and time as parameters.
    In the C# method, first check if either is an empty string, if so return an empty string.
    If not, TryParse the data, if successful, return a valid data string for EventDate.  If not, error or return empty string, whichever satsifies the requirement.

And if you create threads from WC_Collaboration server admin console, there's no data will be selected with FORUMCRAWLER_VW view. Sorry, have no time to check SQL query for those DB view, may be this behaviour is reasonable.

    Hi all,
    Using Acrobat Professional 8, I made a fillable form to individuals to fill in and submit to me as a pdf attachment to an e-mail or print out it and fill by hand.
    Question 1. I want to make sure they don't send incomplete or empty forms back to me. Is there a way to do that?
    2. The form is 8.5x15 inches. I want it to look like one continuous page on screen but print as 2 letter size pages. However, when i go to print it, acrobat scales it down to fit in one page which makes the text too small to read.
    Please advise! Thanks.

    On Question 2:
    when you get to the Print menu in Acrobat/Reader look for scale to fit paper and uncheck if there is a reference to Full size check that.
