Can't you just add your jdk1.5.0_0x/bin folder to your PATH? That's what I did, at least.

Help with HTML and JAVA

Hi.
I'll have this question, and can't find the right answer...
Suppose is this site called xyz.com and you need to register to be a member
For simplicity member log-in page is simple...contains only login and password fields(Submit too) in HTML code:
<html>
<body>
<form name="input" action="html_form_action.asp" method="get">
User ID: <input type="text" name="ID" /><br />
Password: <input type="password" name="pwd" /><br />
<input type="submit" value="Submit" />
</form>
</body>
</html>Will I be able to build a Java application witch will:
1-Send me to this web-page
2-Place my chosen id and password in the right place
3-"Press" Submit button.
So I open this Java Swing application , and Go button will send me to the members page of my xyz.com page.
Thank you for the help.

If you mean access data on the members page through your program, yes.
If you mean open a browser window to that page, I guess doable but might be tricky (with Robot and stuff).
If you mean physically send you on the internet, no.

Need help with mac and java

Hi, I'm trying to develop an application on a Machintosh OSX 10.2.8 machine.
I'm having a herrendous time trying to get quicktime to work on it.
I've somehow managed t oget 1.3.1 and QTJava.jar to work together but now i need encryption, however that requires 1.4+
Now 1.4.1 doesnt work with quicktime
I've downloaded the latest software upgrades but Ive got no idea how to set up quicktime to work with java 1.4.1
Now to add on top of that mac reports it can use AES encryption. this is from source code ripped striaght from this website.
But first and foremost can anyone, annyonee help me out with setting up 1.4.1 with quicktime?
Thank you

If you need encryption with Java 1.3.1, download the JCE from either Sun (http://java.sun.com/products/jce/) or Bouncy Castle (http://www.bouncycastle.org/).

HELP

AFTER I break down and erase the HD and reinstall OSX
You don't have to erase the drive to reinstall the OS. Just reinstall WITHOUT erasing the drive. Only system files will be over-written, and your borked OS will be fixed, while your own files will be left in place. You really should have a backup before a reinstall, but unless one is very unlucky and something goes wrong it isn't strictly necessary.
Never trash anything unless you know what it is, what it does, why it is doing it, and what put it there to do that. I know, it's a bit late for this crisis, but you should now avoid future crises caused by throwing away (or moving) the wrong thing.

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,
C
SAVING THE LIST DATA TO DB
DATA: L_WA(800).
LOOP AT T_TAB into L_WA.
ZDBTAB-DATALEN = STRLEN( L_WA ).
MOVE: L_WA to ZDBTAB-RAWDATA.
ZDBTAB-LINENUM = SY-TABIX.
INSERT ZDBTAB.
READING THE DATA FROM DB

             SEQNR type ZDBTAB-LINENUM,

           END OF T_TAB.
Select the data.
SELECT linenum rawdata from ZDBTAB into table T_DATA
     WHERE repid = w_repname
     AND rundate = w_rundate
     ORDER BY linenum.
Populate calling Internal Table.
LOOP AT T-DATA.
APPEND T_DATA to T_TAB.
ENDLOOP.

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

Help with count and sum query

Hi I am using oracle 10g. Trying to aggregate duplicate count records. I have so far:
SELECT 'ST' LEDGER,
CASE
WHEN c.Category = 'E' THEN 'Headcount Exempt'
ELSE 'Headcount Non-Exempt'
END
ACCOUNTS,
CASE WHEN a.COMPANY = 'ZEE' THEN 'OH' ELSE 'NA' END MARKET,
'MARCH_12' AS PERIOD,
COUNT (a.empl_id) head_count
FROM essbase.employee_pubinfo a
LEFT OUTER JOIN MMS_DIST_COPY b
ON a.cost_ctr = TRIM (b.bu)
INNER JOIN MMS_GL_PAY_GROUPS c
ON a.pay_group = c.group_code
WHERE a.employee_status IN ('A', 'L', 'P', 'S')
AND FISCAL_YEAR = '2012'
AND FISCAL_MONTH = 'MARCH'
GROUP BY a.company,
b.district,
a.cost_ctr,
c.category,
a.fiscal_month,
a.fiscal_year;
which gives me same rows with different head_counts. I am trying to combine the same rows as a total (one record). Do I use a subquery?

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
user610131 wrote:

I am trying to combine the same rows as a total (one record). Do I use a subquery?Maybe. It's more likely that you need a different GROUP BY clause, since the GROUP BY clause determines how many rows of output there will be. I'll be able to say more after you post the sample data, results, and explanation.
You may want both a sub-query and a different GROUP BY clause. For example:
WITH    got_group_by_columns     AS
     SELECT a.empl_id
     ,     CASE
                    WHEN c.category = 'E'
              THEN 'Headcount Exempt'
                    ELSE 'Headcount Non-Exempt'
            END          AS accounts
     ,      CASE
                    WHEN a.company = 'ZEE'
                    THEN 'OH'
                    ELSE 'NA'
            END          AS market
     FROM              essbase.employee_pubinfo a
     LEFT OUTER JOIN mms_dist_copy             b ON   a.cost_ctr     = TRIM (b.bu)
     INNER JOIN       mms_gl_pay_groups        c ON   a.pay_group      = c.group_code
     WHERE     a.employee_status     IN ('A', 'L', 'P', 'S')
     AND        fiscal_year           = '2012'
     AND        fiscal_month          = 'MARCH'
SELECT    'ST'               AS ledger
,       accounts
,       market
,       'MARCH_12'          AS period
,       COUNT (empl_id)      AS head_count
FROM       got_group_by_columns
GROUP BY accounts
,            market
;But that's just a wild guess.
You said you wanted "Help with count and sum". I see the COUNT, but what do you want with SUM? No doubt this will be clearer after you post the sample data and results.

Newbie help with 12i and firefox java issue

We are in the testing stages for a 12i upgrade. I’m currently testing browser and java version compatibility using an upgraded test system. My problem is the version of java on the desktop client. IE7 will launch the apps fine with any version of java. However, any version of Firefox (including just released v3) will not launch java unless java version 5 update 13 is loaded. I’ve reviewed several metalink docs including 389422.1 and 393931.1 and have used the workaround listed forcing FF to use the older version of java. However, that means that we will have to roll out this older version of java to all clients to use Firefox. During my research I found where Oracle provides a techstack update for 11i (290807.1) that will fix this issue and allow Firefox to work with newer versions of java. Has anyone else run into this issue and if so how did you address it? Is there a 12i update that will fix this issue? I’m a newbie that’s started supporting Oracle, etc. so forgive me for any ignorance I show on the subject. Thanks in advance.

Tod,
It sounds like your Oracle E-Business Suite Release 12 instance is configured to request end-users to use JRE 1.5.0_13.
Firefox has a known limitation (or feature, depending on your point of view): it will invoke only the specified JRE version requested by the E-Business Suite, even if later versions of the JRE (e.g. 1.6.0_03) are installed on the same desktop.
This behaviour is explained in more detail in Note 290807.1 in Appendix A. Since this behaviour is hardcoded into Firefox, your options are:
1. Configure your Oracle E-Business Suite Release 12 environment to request a later version of JRE installed on your Firefox-equipped desktops
2. Use IE -- it doesn't enforce static versioning.
3. Contact the Mozilla team and request that they provide a new option to use either static versioning (the status quo) or the latest JRE version installed on the desktop.
Regards,
Steven

Hi,
From your description, you want to achieve the following goal:
Configure Exchange to filter the attachments if the size is over 10 MB and store it in a public folder, and then forward the email to Salesforce.
Based on my knowledge, I'm afraid that it can't be achieved. Exchange can filter messages with attachments, but it couldn't store these attachments on public folder automatically. Also, I don't see any transport rule can do it.
Hope my clarification is helpful.

What's the problem you're having ???

Help with encapsulation and a specific case of design

Hello all. I have been playing with Java (my first real language and first OOP language) for a couple months now. Right now I am trying to write my first real application, but I want to design it right and I am smashing my head against the wall with my data structure, specifically with encapsulation.
I go into detail about my app below, but it gets long so for those who don't want to read that far, let me just put these two questions up front:
1) How do principles of encapsulation change when members are complex objects rather than primitives? If the member objects themselves have only primitive members and show good encapsulation, does it make sense to pass a reference to them? Or does good encapsulation demand that I deep-clone all the way to the bottom of my data structure and pass only cloned objects through my top level accessors? Does the analysis change when the structure gets three or four levels deep? Don't DOM structures built of walkable nodes violate basic principles of encapsulation?
2) "Encapsulation" is sometimes used to mean no public members, othertimes to mean no public members AND no setter methods. The reasons for the first are obvious, but why go to the extreme of the latter? More importantly HOW do you go to the extreme of the latter? Would an "updatePrices" method that updates encapsulated member prices based on calculations, taking a single argument of say the time of year be considered a "setter" method that violates the stricter vision of encapsulation?
Even help with just those two questions would be great. For the masochistic, on to my app... The present code is at
http://www.immortalcoil.org/drake/Code.zip
The most basic form of the application is statistics driven flash card software for Japanese Kanji (Chinese characters). For those who do not know, these are ideographic characters that represent concepts rather than sounds. There are a few thousand. In abstract terms, my data structure needs to represent the following.
- There are a bunch of kanji.
   Each kanji is defined by:
   - a single character (the kanji itself); and
   - multiple readings which fall into two categories of "on" and "kun".
      Each reading is defined by:
      - A string of hiragana or katakana (Japanese phoenetic characters); and
      - Statistics that I keep to represent knowledge of that reading/kanji pair.Ideally the structure should be extensible. Later I might want to add statistics associated with the character itself rather than individual readings, for example. Right now I am thinking of building a data structure like so:
- A Vector that holds:
   - custom KanjiEntry objects that each hold
      - a kanji in a primitive char value; and
      - two (on, kun) arrays or Vectors of custom Reading objects that hold
         - the reading in a String; and
         - statistics of some sort, probably in primitive valuesFirst of all, is this approach sensible in the rough outlines?
Now, I need to be able to do the obvious things... save to and load from file, generate tables and views, and edit values. The quesiton of editting values raises the questions I identified above as (1) and (2). Say I want to pull up a reading, quiz the user on it, and update its statistics based on whether the user got it right or wrong. I could do all this through the KanjiEntry object with a setter method that takes a zillion arguments like:
theKanjiEntry.setStatistic(
"on",   // which set of readings
2,      // which element in that array or Vector
"score", // which statistic
98);      // the valueOr I could pass a clone of the Reading object out, work with that, then tell the KanjiEntry to replace the original with my modified clone.
My instincts balk at the first approach, and a little at the second. Doesn't it make more sense to work with a reference to the Reading object? Or is that bad encapsulation?
A second point. When running flash cards, I do not care about the subtlties of the structure, like whether a reading is an on or a kun (although this is important when browsing a table representing the entire structure). All I really care about is kanij/reading pairings. And I should be able to quickly poll the Reading objects to see which ones need quizzing the most, based on their statistics. I was thinking of making a nice neat Hashtable with the keys being the kanji characters in Strings (not the KanjiEntry objects) and the values being the Reading objects. The result would be two indeces to the Reading objects... the basic structure and my ad hoc hashtable for runninq quizzes. Then I would just make sure that they stay in sync in terms of the higher level structure (like if a whole new KanjiEntry got added). Is this bad form, or even downright dangerous?
Apart from good form, the other consideration bouncing around in my head is that if I get all crazy with deep cloning and filling the bottom level guys with instance methods then this puppy is going to get bloated or lag when there are several thousand kanji in memory at once.
Any help would be appreciated.

Usually by better design. Move methods that use the
getters inside the class that actually has the data....
As a basic rule of thumb:
The one who has the data is the one using it. If
another class needs that data, wonder what for and
consider moving that operation away from that class.
Or move from pull to push: instead of A getting
something from B, have B give it to A as a method
call argument.Thanks for the response. I think I see what you are saying.. in my case it is something like this.
Solution 1 (disfavored):
public class kanjiDrill{ // a chunk of Swing GUI or something
     public void runDrill(Vector kanjiEntries){
          KanjiEntry currentKanjiEntry = kanjiEntries.elementAt(0); // except really I will pick one randomly
          char theKanji = currentKanjiEntry.getKanji();
          String theReading = currentKanjiEntry.getReading();
          // build and show a flashcard based on theKanji and theReading
          // use a setter to change currentKanji's data based on whether the user answers correctly;
}Solution 2 (favored):
public class kanjiDrill{ // a chunk of Swing GUI or something
     public void runDrill(Vector kanjiEntries){
          KanjiEntry currentKanjiEntry = kanjiEntries.elementAt(0); // except really I will pick one randomly
          currentKanji.buildAndShowFlashcard(); // method includes updating stats
}I can definitely see the advantages to this, but two potential reasons to think hard about it occur to me right away. First, if this process is carried out to a sufficient extreme the objects that hold my data end up sucking in all the functionality of my program and my objects stop resembling natural concepts.
In your shopping example, say you want to generate price tags for the items. The price tags can be generated with ONLY the raw price, because we do not want the VAT on them. They are simple GIF graphics that have the price printed on a an irregular polygon. Should all that graphics generating code really go into the item objects, or should we just get the price out of the object with a simple getter method and then make the tags?
My second concern is that the more instance methods I put into my bottom level data objects the bigger they get, and I intend to have thousands of these things in memory. Is there a balance to strike at some point?
It's not really a setter. Outsiders are not setting
the items price - it's rather updating its own price
given an argument. This is exactly how it should be,
see my above point. A breach of encapsulation would
be: another object gets the item price, re-calculates
it using a date it knows, and sets the price again.
You can see yourself that pushing the date into the
item's method is much beter than breaching
encapsulation and getting and setting the price.So the point is not "don't allow access to the members" (which after all you are still doing, albeit less directly) so much as "make sure that any functionality implicated in working with the members is handled within the object," right? Take your shopping example. Say we live in a country where there is no VAT and the app will never be used internationally. Then we would resort to a simple setter/getter scheme, right? Or is the answer that if the object really is pure data are almost so, then it should be turned into a standard java.util collection instead of a custom class?
Thanks for the help.
