If you do want TCP packet sniffing, I'm afraid Java networking API doesn't support such low-level. The GUI should be easier though.

Aggregating table - how to solve this with ADF Faces

Hello.
I am trying to solve something that would typically be really simple. However, now i' using ADF faces which is new to me and i'm stuck.
I want to show a table of rows with aggregated numbers (department in example below) and then "open up" any row by clicking on it to display the numbers that make up the aggregate (the guys in the helpdesk department in the example below).
Something like this:
DEPARTMENT SALARIES
+Sales 1.234.567
+Warehouse 3.425.553
-Helpdesk 655.000
Joe 155.000
Jill 300.001
Burt 199.999
+Personnel 546.225
+Management 9.646.383
And to make things more complicated, some of the aggregate rows in my real life example don't have any underlying rows. They just have the total. Can anyone give me hint about how to do this with an ADF Faces-control? I need to show management this can be solved quick and simple with ADF Faces, so i can convince them that it is the way we should be working in the future.
Edited by: GoodCoffee on Jun 2, 2009 4:15 AM. Trying to indent the three rows under "Helpdesk"

Hi,
if you use ADF BC as the business Service then you can create a transient attribute (one that does not ave a database column ) and compute the total. Using JDeveloper 11g, you can use a Groovy expression. The below example calculates the Overall Salary paid by an department. The transient attribute is defined on the Department Entity Object
XML View
<Attribute
 Name="SumSalary"
 ColumnName="SUMSALARY"
 SQLType="NUMERIC"
 Type="java.lang.Long"
 ColumnType="NUMBER"
 IsQueriable="false"
 IsPersistent="false">
 <TransientExpression><![CDATA[Employees1.sum("Salary")]]></TransientExpression>
</Attribute>The Employees1.sum("Salary") string is the Groovy expression that you need to add for the attribute. You select the created transient attribute in the EO editor and press the pencil icon. Then you select "Expression" as the value type and add the string.

I used to drag and drop newly loaded CD's from Recently Added to one of my iPod Classic playlists. I have no idea how to do this with the new version of iTunes. I thought perhaps checking Sync might give me a clue but it warned me Syncing would wipe conte

I used to drag and drop music loaded from CD's from the Recently Added folder to a Playlist on my iPods Classic. Can't see how to do this with new iTunes version. Probably need to sync somehow but when I checked on Sync it warned me it would wipe out my iPod contents. Don 't know why Apple makes something that used to be simple so difficult. Can't even figure out how to display both my library and iPod contents on same screen.

Hey joshuafromisr,
If you resintall iTunes, it should fix the issue. The following document will go over how to remove iTunes fully and then reinstall. Depending on what version of Windows you're running you'll either follow the directions here:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
http://support.apple.com/kb/HT1925
or here:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7

How to do this with message mapping in PI ?

Hi All,
Field 1 = 100 characters having values in first fifty characters and last 50 characters blank . I need to remove all the first 50 characters with blank and pass 100 blank characters .How to do this with message mapping
Thanks

Adding to that, since usually a tab = 8 spaces. What you can do is to open notepad, press tab 4 times. Copy it and paste 3 times, afterwards press space 4 more times and you get 100 spaces.
Regards,
Mark

It may be due to Continuity

You posted a thousand lines of badly-formatted code and didn't have the sense to say which one had the exception.
My guess is that it was this one:Session session = Session.getDefaultInstance(props, null);because that happened to me. I fixed it by calling getInstance instead of getDefaultInstance.
However if that isn't the problem, how about spending a few seconds to post a less useless question?

How to use connec with java 6.0 ?

I often use the function below to connect Database:
public Connection getConnection(){
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn=DriverManager.getConnection("jdbc:odbc:EmployeeManagerDB","sa","sa");
System.out.println("Get connection successfully!");
catch(Exception e){
System.out.println("Error: " +e);
return conn;
but now, with Java 6.0 . don't use "class.forName....for method"
can you tell me how to use it??
thanks !

but now, with Java 6.0 . don't use
"class.forName....for method" Where did you get this idea?He's perfectly correct. JDBC 4.0 takes advantage of the Java SE Service Provide mechanism in Java 6 to do away with the requirement. So, if you have Java 6 and a JDBC 4 driver (it's a mandatory feature) you simply omit the forName() call.
The only problem is that there aren't that many complete JDBC 4 drivers out there yet.

How to solve this ERROR --java.lang.OutOfMemoryError: Java heap space

I am Trying to read one TEXT file line by line. file size is approx. 7 MB or it contain approx. 35000 line of text.
i am processing that file and export data into another file.
mean while after some line i get error like below,
java.lang.OutOfMemoryError: Java heap space
After this error process stop.
my application is in Java Swing and i m using java 1.5 version of SDK and JRE.
is it a JDK version Problem?
please can any one give me appropriate solutions for this.
give me answer please.............

Are you able to post the code you use to read the file? Initially, I'd guess that you're stuck in a loop. Make sure you're getting out of all your loops. You can do this with breakpoints in your IDE's debugger, or by putting a println right after the loop.
It may also be that your IDE isn't allotted enough of your system's memory, though I doubt that is the case. You can easily google how to increase the memory allotted to the IDE.
For some reason, garbage collection isn't happening as you're expecting. Make sure you're not holding on to huge stuff any longer than you need to.

How to realize them with Java Swing?

2.I want to set Font and color in the text area. I can do it now. But I must set the font and color b4 input the words. How can I do it like Windows Word - I just input my words, then I highlight them and select the font and colour....all highlighted words r change....can I don it with Java swing and how?

How to solve this error java.util.MissingResourceException

Hi Friends,
I had developed one web dynpro application by using Internationalization - I18N of WebDynPro (Java) Application (Blog) but I got one error that is
java.util.MissingResourceException: Can't find bundle for base name com.sap.example.language.lang, locale en_US
Actually i created two properties file
1. lang_en.properties
2. lang_ta.properties
I stored this two properties file in this package com.sap.example.language
and this my code in DOInit()
sessionLocale = WDClientUser.getCurrentUser().getLocale();
resourceHandler = ResourceBundle.getBundle("com.sap.example.language.lang",sessionLocale);
 catch (WDUMException e)
 e.printStackTrace();
 wdContext.currentContextElement().setUsername_label(resourceHandler.getString("testview.username"));
 wdContext.currentContextElement().setPassword_label(resourceHandler.getString("testview.password"));
How to solve this error?
Guide me.
Advance Thanks,

Should I do this with Java Code or Stored Procs ? (for best performance)

Hi All,
I need to decide where should I implement my business logic, in Java code or Stored procs.
Here is the requirement :
- One Order has 70 products (Order_Table )
- Can be duplicate products, so I have to do summarize / grouping by product
- For every product, I have to check, if it is entitled for a Bonus product, then I have to Insert one to Bonus_Table.
- This is done when/after the transaction is SAVED (COMMIT)
The question is, which one has better PERFORMANCE :
(1) Create a rowsetIterator on the Order details (70 products) and call a stored procedure to do the logic for every single product (so that the Insert to Bonus_Table done in stored proc). means the stored proc will be called 70 times.
OR
(2) After the transaction is COMMITted, call the stored procs ONCE to do the logic for all the products at once.
OR
(3) I do all the logic with Java Code within ADF
Given the requirement above, which approach is most efficient / best performance ?
Thank you very much,
xtanto

Problem with this is that you ask 100 people and you probably get 100 different answers. ;o)
Many would say that you push as much business logic into the database with your data; others might say you only put data in your database and your business logic is kept on the application server.
In reality your would probably have a mix of both and your decision would probably be influenced by your own background ...
Can't be more precise than that.

How to do this with Logic?

Hy!
Any ideas how i can realize this with Logic?:
http://www.youtube.com/watch?v=tE7GHgbmlP0
Are there any (freeware) loop plug ins or something else I could use?

Yea, but what if we want to make our own loops, instead of using what apple is providing?
If you're questioning whether you can make your own music loops in Logic as opposed to just using Apple Loops, then you're totally misunderstanding some of the most basic functioning of Logic. That's like asking whether you car will drive you around the block. Logic is a very complex multi track audio and midi sequencing program. Not only can you make any type of sound or audio or midi sequence and loop it to your heart's delight, you can make multi track sequences, songs, complex orchestral arrangements, movie scores, soundscapes .... shall I go on?
I just got LP8, and I'm just learning it too. Are you really saying that you can't do anything similar to that video with Logic?
Absolutely not!! In fact, SC's post 4th down tells you how to do something similar. Not EXACTY what's in the video, but SIMILAR.
Here's the difference: You can't record a single measure drum beat and then have it automatically loop indefinitely *in real time* while you layer more drum beats onto it, each one being recorded after a single measure and played back without stopping. In Logic, you can record a measure, then tell Logic to loop it, and then create another, loop that one, etc etc. The only difference is you're not doing it in 'real time' without stopping, you're building a sequence of looped sounds manually in the arrange. The OP seems to want to do it live, without the beat stopping. For that you need Ableton or another program with 'real time looping' capabilities. The only reason you'd want to do this would be if you A) want to impress your friends, or B) are trying to create beats in a live situation, like a club or something. If that's what you're after, other programs like Ableton Live are better suited for that.

How to sort taxonomy with Java api? Please Help

Can someone please help me out? I understand and can display the contents of a taxonomy. But I need it to be displayed in alphabetical order. Manual ordering does not exist for taxonomies. How do you sort a taxonomy in java?
The following snip of code can get the taxonomy and loop through it but isn't ordered correctly. Can some kind of comparator be used somehow? Points will be rewarded! Please help.
//Get connection to KMCM path
RID rid = RID.getRID(strPathToKMCM);
IResource resource = ResourceFactory.getInstance().getResource(rid, context);
ICollection collection = (ICollection) resource;
IResourceList children = collection.getChildren();
for (int i = 0; i < children.size(); i++){
IResource ir = children.get(i);

I'd also be interested to know how to do this.
I found this code section to sort by date, but couldn't change it to get it to work to sort alphabetically.
private void sortResouceListByDate(IResourceList resourceList) throws Exception {
// create property names to index properties
IPropertyName iPropSort = new PropertyName("http://sapportals.com/xmlns/cm", "modified");
//create a comparator to order the resource list
ResourcePropertyComparator rRPC = new ResourcePropertyComparator(iPropSort, false);
//order the resource list
resourceList.sort(rRPC);
