JAXB Hashtable instead of List

Hi,
I'm new using JAXB, I apologize if it is a to basic question.
I've already searched for a solution for the problem described below on google, and also on this forum with no success.
I appreciate if someone could help me.
First question:
1)What is the best approach to develop with JAXB??Should I create the java classes first, and then generate the XSD using the "schemagen" tool??or should I create the XSD file first, and then use the tool "xjc" to generate the java classes?
2)One of my java classes have an Hashtable attribute like this example:
Public class ems{
private Hashtable mapping;
}However, when I run the "schemagen" tool, then it generates the XSD like the code below:
<xs:complexType name="ems">
    <xs:sequence>
      <xs:element name="mapping" type="xs:anyType" nillable="true" maxOccurs="unbounded" minOccurs="0"/>
    </xs:sequence>
</xs:complexType>The issue is that I don't know how to unmarshal/ marshal collections attributes that are HashTable (or any other collection different from List).
Please, Does somebody know what should I do in order to solve this issue?
thanks in advance,
Roger

It is still showing a list. So yes I can click artist or album and it will show that album or artist in alpha or reverse alpha. And this is of course if my id3 tag has an album which some do not so when I drag a folder of music without specific id3 tags they can simply get lost in the list.
Where as I figured I could drag each folder and it would keep that folder so I could select each folder as I had them organized in my music folders to begin with.
I have a lot of music and not all of it has id3 tags that will properly show up even when I click the category buttons.
What I am trying to do is find a method in which I can have folders rather than a list view for each folder I upload/download to my iPad.
Coming from a PC this functionality seems fairly simple but I am not able to find it inside iTunes.

Image instead of List Name, and hyperlink the image to view 'All Items.aspx' page

Hi,
I would like remove the Page title for list (i.e., name of the list in view all items.aspx page) , and instead use image and hyperlink the image
to 'All items.aspx" page.
Using developer tool found the element (#PageTitle) and added 'Script Editor' webpart and below css script to it. I am successful in replace the
title to image, however, I am unable to add the HTML tag for hyperlink. Where do I need to add or how do I add? Could anyone help me please??
<style type="text/css">

</style>
Regards,

Hi Sunitha,
According to your description, my understanding is that you want to change the list title to an image.
I recommend to add the code below to the list page:
<script src="http://code.jquery.com/jquery-1.10.2.min.js" type="text/javascript"></script><script type="text/javascript">
$(document).ready(function (){
var s = "<img alt='SP' src='http://w2k81368:2116/SiteAssets/Test.jpg'>";
var $t = $("#DeltaPlaceHolderPageTitleInTitleArea span span a");
$t.html(s);
</script>
After that, the list title will change to the image and it will show allitems.aspx page when clicking the image.
Thanks,
Victoria

Search Index says Normal Template instead of listing the help page names

Hi
when I type a search word into the Java Help Find text box. The search system lists relevant pages (in the pane underneath the Find text box) but instead of giving the page titles it just says "Normal Template".
Does any one know how I can fix this?
Thanks.

Edit your html file and enter the title you want displaying between the two tags shown. <TITLE>hgashgas</TITLE>
Yours probably has the text Normal Template in here.
Hope this helps.

Popup instead of list when using WD4A ALV Grid Drop Down By Key

I am develop a WD4A application and I am using an ALV grid. I have set the cell editor for one column wiht the following code:
CREATE OBJECT lr_ddbk
    EXPORTING
      SELECTED_KEY_FIELDNAME = 'ZCURRENCY'.
Data: lv_key_visable TYPE abap_bool,
        lv_key_visible_fieldname TYPE string.
   lr_ddbk->set_type( if_salv_wd_c_uie_drdn_by_index=>type_key_value ).
* lv_key_visable = lr_ddbk->GET_KEY_VISIBLE( ).
* lv_key_visible_fieldname = lr_ddbk->GET_KEY_VISIBLE_FIELDNAME( ).
* lr_ddbk->SET_KEY_VISIBLE( abap_false ).
lr_alv_column->SET_CELL_EDITOR( lr_ddbk ).
This code works fine. I then fill the drop down with the following code:
*...Build the currency drop down list
DATA lv_default_currency TYPE wdr_context_attr_value.
DATA lv_currency_count TYPE STRING.
DATA ls_tcurt TYPE tcurt.
CLEAR ls_contextvalue_set.
CLEAR lt_contextvalue_set. REFRESH lt_contextvalue_set.
CLEAR lv_default_currency.
loop at it_ac_attr into ls_ac_attr.
    if ls_ac_attr-attr_id eq 'CUR'.
      select single * from tcurt into ls_tcurt
           Where spras = 'EN' AND
                 waers = ls_ac_attr-value.
      If sy-subrc = 0.
        ls_contextvalue_set-value = ls_ac_attr-value.
     ls_contextvalue_set-value = ls_ac_attr-value.
        ls_contextvalue_set-text = ls_tcurt-ktext.
        IF ls_ac_attr-DFT_FLAG = 'X'.
          lv_default_currency = ls_contextvalue_set.
        ENDIF.
        append ls_contextvalue_set to lt_contextvalue_set.
      endif.
    Endif.
endloop.
lo_nd_zebuy_describe_item_info = lo_nd_zebuy_describe_item->get_node_info( ).

                                   name = 'ZCURRENCY'
                                  value_set = lt_contextvalue_set ).
*...End build currency drop down list
This code works fine. The issue I am having is that the drop down is behaving like a search help field rather than a drop down list. Meaning a popup comes when I drop down the list. The popup has the values I have set. I don't want a popup I want a drop down list. Additionallly the field is editable (meaning I can type a value into the field as well as select a value). I want the user to only be able to select values from the list. Any help with this issue would be appreciated.

I fugured out what I was doing wrong. I was setting the cell editor to cl_salv_wd_uie_input_field later in the code by mistake.

Instead of pointing to local files, re-matched library lists all local files as duplicates

I've got a mess. I moved my matched local music files from my internal drive to a larger external drive. I deleted the iTunes folder on the internal drive, created a new library by changing the location of my music library in iTunes preferences and adding all of the files on the external drive.
When I turned match back on, my cloud-based matched files no longer pointed to my local versions. Instead, match listed everything as a duplicate -- a copy in the cloud and a local copy even though the two copies are exactly the same, previously matched files.
I've added files to my cloud library from numerous computers -- so my cloud library is the most complete -- and I was in the process of creating one local, consolidated library on my new external drive by downloading those files from match. There has to be a way to re-sync both local and match libraries with everything matched as it previously was withouth having to either delete and re-upload or delete and re-download.
Any tips, instruction or help will be greatly apprieciated.

You didn't move the library in the right way. In the future, use this Apple KB article to move an iTunes Media folder: http://support.apple.com/kb/ht1449
To try to clean this up is going to take some work on your part but it isn't impossible. Start off with one album or artist at a time and delete them from the cloud. Then you should be able to select the corrosponding locally stored tracks, right click them, and choose "add to iCloud." This should re-initiate a scan on those tracks and add them to the cloud.

Getting a list instead of a single record.

Hello Experts,
I’m trying to get a record out of a table with the highest amount of money. I’ve used the following query to get the maximum about of money sitting in the table and it gave me the results.
SELECT MAX(auction_item.item_highest_bid)
FROM `auction_item`
I also need two more fields from the same table. Item_id and seller_id. Now what happens is when I write the following SQL I get a list of records instead of a SINGLE record with the highest amount of money.
SELECT MAX(auction_item.item_highest_bid),
auction_item.item_id,
auction_item.seller_id
FROM `auction_item`
GROUP BY auction_item.item_id,
auction_item.seller_id
Can please somebody shows me what’s wrong with my query and how I can get SINGLE record instead of list.
Thanks a lot in advance.

There are several ways to get this information - subqueries, analytical sql. A lot of it depends on the data.
Is there a possibility that two or more records will have the same MAX(auction_item.item_highest_bid)? And if so, how is this to be handled? I'm making some assumptions about item_id and seller_id...so take with a grain of salt
As an aside...you need to read up on GROUP BY and aggregation in sql as this scenario is explained in documentation/books.
Without the benefit of a database to test this, here are a couple of ideas
SELECT MAX(auction_item.item_highest_bid),
auction_item.item_id,
auction_item.seller_id
FROM auction_item
WHERE auction_item.item_highest_bid = (SELECT MAX(i_auction_item.item_highest_bid)
FROM auction_item i_auction_item
WHERE i_auction_item.item_id = auction_item.item_id
AND i_auction_item.seller_id = auction_item.seller_id)
Or
SELECT i.item_highest_bid, i.item_id, i.seller_id
FROM (SELECT a.item_highest_bid, a.item_id, a.seller_id
FROM auction_item a
ORDER BY a.item_highest_bid DESC) i
WHERE i.rownum = 1
Or
SELECT i.item_highest_bid, i.item_id, i.seller_id
FROM (SELECT a.item_highest_bid, a.item_id, a.seller_id, ROW_NUMBER() OVER (ORDER BY a.item_highest_bid DESC) bid_rank
FROM auction_item a) i
WHERE i.bid_rank = 1

Casting Hashtable to list

Hi
My evil teacher has given me an assignment that include casting a Hashtable to a list. I get no error when compiling,building or running the project, but when i try printing the list i get loads of errors. I am not a very experienced programmer so please keep the answer simple :D
public List getPerson(String aKey, String value){
List list = (List) contactList;
Iterator persons = list.iterator();
if(aKey == "name"){
while(persons.hasNext()){
Contact con = (Contact) persons.next();
if(con.getName().equals(value)){
list.add(con);
return list;
}

Take a look at the javadocs, and see if you can come up with a solution.
Maps contain key-value pairs (like a dictionary, you can look up a value if you have the key).
Now with that information, can you see any way to get a collection of keys, or values from a Map (Hashtable is an implementation of a map)

Jdeveloper- web service- can't produce wsdl for java List

Hi-
I think this is a jdeveoper bug. It looks like the same bug as #4706306 in Jdeveloper 10g bugs.
There is a workaround suggest to use additional classes in the web service. But it does not work on 11g.
Details of the problem ........
I am trying to create a web service and client using jdeveoper 11g.
For some reason, the wsdl generated from the jdeveoper is incorrect. My java classes used List.
Apparently, jdeveoper does not like List . I can reproduce the problem using three files as attached.
the files are 1)Baby.java, 2)Papa.java, and 3)MyCall.java. The webservice is MyCall Class and the web method is getPapa().
After I created the web service and its wsdl, I then used the wsdl to create a client. then files are generated from the
wsdl for client . One of the file as in 4)Papa.java has a wrong List<Object>. It should be List<Baby>.
I can't move forward because of this problem. If any one can help, I'll be very appreciated.
Thanks!

Try using Collection instead of list so:
Collection<Baby> babyList = new ArrayList<Baby>();

JAXB External Binding to java.util.Collection

Hi,
By default jaxb converts xsd:sequence to java.util.List. Is there any way to specify that during compilation it will use java.util.Collection instead of List?

Confusion over Context.list and listBindings

Sorry for this newbie question.
How do I list all the bindings I have created? Working on Windows, the JNDI service creates a file called .bindings, which holds all the bindings. I can bind, unbind, rebind and lookup fine. But I cannot list the bindings.
Here is sample code to illustrate what I mean.
import java.util.*;
import javax.naming.*;
import sun.jdbc.odbc.ee.DataSource;
public class Test {
    public static void main(String[] arg) throws NamingException {
        final DataSource ds1 = new DataSource();
        final DataSource ds2;
        final Hashtable env = new Hashtable(2);
        final Context ctx;
        // Bind a DataSource to the name "MyTest". The ".bindings" file
        // goes into "C:\My Documents".
        env.put(Context.INITIAL_CONTEXT_FACTORY,
                "com.sun.jndi.fscontext.RefFSContextFactory");
        env.put(Context.PROVIDER_URL, "file:C:/My Documents");
        ctx = new InitialContext(env);
        ds1.setDatabaseName(";FILEDSN=MyTest");
        ctx.bind("jdbc/MyTest", ds1);
        // Verify that the DataSource was saved where we can look it up.
        // I have used this method in several programs and it works
        // perfectly.
        ds2 = (DataSource) ctx.lookup("jdbc/MyTest");
        // Look up the current bindings.
        // This is the part where I'm doing something wrong.
LookUpCurrentBindings :
        for (final NamingEnumeration ne = ctx.list(""); ne.hasMore(); ) {
            final NameClassPair ncp = (NameClassPair) ne.next();
            // I expect the following to show "jdbc/MyTest", but instead
            // it lists the files in the directory "C:\My Documents".
            // For example, "desktop.ini" and ".bindings".
            System.out.println(ncp.getName());
}Thanks for your help!

Aha! I found out what the problem was. It was indeed to do with my "newbie" status in JNDI, not understanding some basics. If the .binding file is in a directory of its own, in this case jdbc, it works! Specifically:
(1) Create the context jdbc within the directory (this creates the directory C:/My Documents/jdbc).
(2) Bind the names within that directory (e.g. MyTest instead of jdbc/MyTest).
(3) The list() and listBindings() functions list both the .binding file (class java.io.File) and the bound objects (their correct classes, in this case sun.jdbc.odbc.ee.DataSource).
Here is the code that I used.
import java.util.*;
import javax.naming.*;
import sun.jdbc.odbc.ee.DataSource;
public class Test2 {
    public static void main(String[] arg) throws NamingException {
        final DataSource ds1 = new DataSource();
        final DataSource ds2;
        final Hashtable env = new Hashtable(2);
        Context ctx;
        // Create a context called "jdbc" within the base directory.
        env.put(Context.INITIAL_CONTEXT_FACTORY,
                "com.sun.jndi.fscontext.RefFSContextFactory");
        env.put(Context.PROVIDER_URL, "file:C:/My Documents");
        ctx = new InitialContext(env);
        try {
            // Find the "jdbc" directory as a Context.
            ctx = (Context) ctx.lookup("jdbc");
        } catch (NamingException e) {
            // Create the "jdbc" directory as a Context.
            ctx = ctx.createSubcontext("jdbc");
        // Bind the new DataSource in the context to the name MyTest.
        ds1.setDatabaseName(";FILEDSN=MyTest");
        ctx.bind("MyTest", ds1);
        // Verify that the DataSource was saved where we can look it up.
        ds2 = (DataSource) ctx.lookup("MyTest");
        if (! ds1.getDatabaseName().equals(ds2.getDatabaseName())) {
            throw new IllegalStateException("Oops, something funny happened.");
        // Add another binding, just for fun.
        ctx.bind("ForGoodMeasure", ds2);
        // Look up the current bindings. This displays the file .bindings
        // (class java.io.File) and the bindings within that file (class
        // sun.jdbc.odbc.ee.DataSource).
LookUpCurrentBindings :
        for (final NamingEnumeration ne = ctx.list(""); ne.hasMore(); ) {
            final NameClassPair ncp = (NameClassPair) ne.next();
            System.out.println(ncp.getName() + "\t\t" + ncp.getClassName());
        ctx.close();
}And here is the output.

Generics with JAXB and Unchecked Conversions

If there is a more appropriate forum for JAXB related posts, my apologies, I browsed the list and didn't see one.
Here's my schema:
     </complexType>
     <element name="songList"
          type="com:songListType"/>
     <complexType name="songListType">
          <sequence>
               <element name="songList"
                    type="string" minOccurs="0" maxOccurs="unbounded"/>
          </sequence>
     </complexType>And my question os
Is there a way to get JAXB to generate a class that has a method lie
List<String> getSongList();Instead of
List getSongList();I'd like to eliminate the unchecked conversions. If anyone has any suggestions or can reference a tutorial, I'd greatly appreciate some tips.
Thanks

Wow, sorry for all the typos btw

JTable + Hashtable + Collection doesn't seem to work properly

Hi folks,
I'm having a problem with JTree class. Basically, I want to instantiate it by using an Hashtable, though
depending on the fact that I use collection or arrays the result can substantially vary.
Take the following use case:
import javax.swing.*;
import java.util.*;
public class Tree extends JApplet{
public Tree(){
    super();
    setSize(300, 250);
    init();
    setVisible(true);
public void init(){
    Hashtable<String,List<String>> hash = new Hashtable<String,List<String>>();
    hash.put("Foo", Arrays.asList("Bar"));
    JTree tree = new JTree(hash);
    getContentPane().add(tree);
}This displays a wrong tree, in fact you should have a Foo node that contains a Bar leaf.
Now if I use array instead of collections (generics are not the problem) everything work just as
expected!?
import javax.swing.*;
import java.util.*;
public class Tree extends JApplet{
public Tree(){
    super();
    setSize(300, 250);
    init();
    setVisible(true);
public void init(){
    Hashtable<String,String [] > hash = new Hashtable<String,String []>();
    hash.put("Foo", new String []{"Bar"});
    JTree tree = new JTree(hash);
    getContentPane().add(tree);
}Considering that the constructor of JTree allows the following instantiation for Hastable:
public JTree(Hashtable<?,?> value)the use of wildcards let me assume that I can put whatever I like as the type of my keys/values.
Am I missing something or this is indeed some very strange (buggy) behavior.
Cheers,
Mirco

If you look in the source code for JTree, there's no mention of Lists in there. Not quite sure why they handle Vectors and Hashtables only instead of Lists and Maps.Hi lins,
thanks for taking the time for giving me your though.
I have take a glance at the javadoc for method createChildren, but once again it tells me that if I have an entry of the type
<A,Collection<B>> I should get a Node named after the object of type A and whose leaf are the ones contained in the collection.
I agree with you that is bizarre that the JTree constructor only accept Hashtable (and not Map, that appear to me more convenient);
but I can live with that as long as the value field of the hashtable behave as I would expect.
I'm not an experienced Java programmer, so if any of you gurus has any thoughts on that, please let me know.
Cheers,
Mirco

Upload multiple files to a data item in sharepoint list

The image above shows a list item with two pdf files attached to it. This is an access databse that was pushed to this sharepoint list. When we attached these files we used the "attach file" from the edit menu at the top of the page.
They are put into a data item called "copy of sepration report", which I can't seem to find when I edit the list. As a further on discussion of this we would like to be able to upload multiple items into their own data field. I.E.
one could be seperation report, and another could be accidents, and another would be disciplinary. Each would have the capability of having multiple items uploaded to it.
What am I missing????

Since you can't attach document to list item field, you may need to think other way around. You can create a document library and have the document library all these fields (separation report, copy of separation report etc.). So instead of list item having
the documents attached, the document library will have the fields attached. Also you can group the fields into two groups - fields that are not directly related to document and fields that are directly related to document. Then you can move the document related
fields to document library and create another list with the non-related-to-document fields and linking this new list to document library using lookup
