General question on applets and proxies

I noticed that while recently surfing the web using an anonymous proxy that a web site I went to running a java chat applet was able to display my true ip address.
Does anyone know how this is done?
Does the server run an applet that bypasses the browser settings?
Any info would be appreciated.
Thanks.

Question regarding Applet and JVM

Hi all!
I'm working on an applet now and it's been working quite fine, just that when I run the same applet on different tab in a single browser window, it'll get some error.
But if I run the applets in different windows, it'll be fine.
So I'd like to know how does JVM handle the execution of applet?
What is the difference between:
- how JVM handles multiple applet in different-tab-in-single-browser and
- how JVM handles multiple applet in different browser?
Any help is greatly appreciated :)
Thanks in advance ^^

Sounds like you're using static fields. Not a good idea in applets because...
What is the difference between:
- how JVM handles multiple applet in different-tab-in-single-browser and
- how JVM handles multiple applet in different browser?
...that's entirely up to the browser. Actually, your question's slightly misconstrued. What you should really ask is,
What is the difference between:
- how the browser spawns JVMs in different-tab-in-single-browser and
- how the browser spawns JVMs in different browser?
Either way, it's out of your hands. Which is why you're going to have to be very careful about using statics: if you use them for state information then another applet can trash them; if you use them for inter-applet communication you might not reach one applet from another.

General questions on IDOCs and IDOCs for 2 Accounting Interface BAPIs

This post involves several questions pertaining to the topic of IDOC creation. I downloaded a couple of PDFs and tried googling for material on that, but things are far from being clear in my mind.
I tried to put my questions in some order, so we can follow a line of reasoning. Here we go, then:
I have one code where I there are calls to 2 BAPIs:
- BAPI_ACC_ACT_POSTINGS_REVERSE and
- BAPI_ACC_GL_POSTING_REV_POST
I am supposed to prepare/create an IDOC to perform the activities these BAPIs are responsible for, for the sole purpose of providing us much more details on the activities being executed in the system - this is one of the IDOC's features, if I got it right, its highly detailed logging of everything that is going on behind.
Now, the 1st question arises:
From the material I read, I understood that IDOCs are nothing more than data containers, whose sole purpose is to provide a means of communication between two different systems/parties - one of them would usually be SAP. If this is right, than what sort of IDOC would be this one I am supposed to build - if there's not going to be any inter-system communication ? Doesn't it sound strange that pure "data containers" can work as "logging functions" ? Please share some light here.
The 2nd question - after I understand what an IDOC really is - is
then connected to the job I have to do. I found 2 IDOCs which I think have the proper/correspondent basic types for the 2 aforementioned BAPIs. They are, respectively:
- ACC_DOCUMENT_REVERSE01 and
- ACC_GL_POSTING_REVERSE01
Getting back to my understanding of IDOCs, I got that every IDOC is generally made of one control record, data record(s), and status record(s). 3rd question: Where do the segments fit in ? Are the segments definitions of the Data Records ? And why is it that some IDOC types have header segments only and others doesn't have one ? (header segments are not the same as control records, right ?)
Finally, what is the general process flow for creating/preparing an IDOC ? I looked over a couple of forum posts about this but some of them differ one from another in the order of the steps, some don't mention this or that step, so I am still confused.
4th and last question: what comes first ? The definition of a partner, the bonding of a message type with an IDOC basic type, definitions of the inbound/outbound interfaces ?
Any help here would be highly appreciated.
Thanks in advance,
Avraham

Hi Jaya,
Answer 1. Class is a template for creating objects. Object can also be called as instance.
Interfaces allow you to use different classes in a uniform way (polymorphism).
Answer 2. Normal abap is a procedural programming where as by using abap objects we can achieve object oriented programing.
Answer 6. Source code:
In below code i have created a interface and a class which is implementing the interface. I have declared a reference variable of type interface and created a object. Then i have called a method.
REPORT ZABAPOBJECTS_INTERF.
      INTERFACE I1
INTERFACE I1.
METHODS METH1.
ENDINTERFACE.                    "I1
      CLASS C1 DEFINITION
CLASS C1 DEFINITION.
PUBLIC SECTION.
    METHODS: METH2.
    INTERFACES: I1.
ENDCLASS.                    "C1 DEFINITION
      CLASS C1 IMPLEMENTATION
CLASS C1 IMPLEMENTATION.
METHOD I1~METH1.
    WRITE: / 'This is a method one'.
ENDMETHOD.                                                "I1~METH1
METHOD METH2.
    WRITE: / 'This is a method two'.
ENDMETHOD.                                                "METH2

START-OF-SELECTION.
DATA : REF1 TYPE REF TO I1.
CREATE OBJECT REF1 TYPE C1.
CALL METHOD REF1->METH1.
Question 7: Yes we need to create a class but most probably we use the existing classes.

General Question on Profiles and when to use them

Hi
I have inherited a database, from our previous DBA. Recently one of our user password expired causing access issues within our application.
On investigation, I noticed that we have a default profile, with the password expiration in place.
We want to make the password expiration to be unlimited.
My question is, what is the best practice for doing this?
Is it recommended to create a seperate profile, other than the default or
Is it OK to just keep one profile remove the restriction on that profile.
Our database contains only 3 users (outside the oracle users) which are, the schema owner, 2 web users for different functionality.
If there are best practices documented, then I'm willing to read through it, if someone can point me to it. Currently I have only found, documentation on profles and how they are used, but none show what are the best practices recommended for oracle.
Thanks in advance.
Div.

Hi Helios
Thank you for your response.
I read the below :
Password Management is setup by DBAs using Oracle Profiles. A general recommendation is to assign only those schemas a profile with password aging an expiration features if the users have the ability to independently change their password from their end-user application when the password expires, usually this means the application they use must have correctly implemented the OCIPasswordChange() OCI call such as sqlplus.
So would you recommend that I just keep my default profile and set the password expiration to unlimited, as that is what I understand from the above.
Thank you for your quick response.
thanks

General question about Applets!

Hi,
I have a Win program I need to upgrade as a Web one.
So, I'm not sure whether I should use an applet whetther do it with JSPs...
I've used Java applets 4 years ago and I met some printings, (very)long downloading, security, ...problems.
Obviously, the graphic result would be much better for me with an applet but could you please tell me if Java applets for Java 1.4.1 is more reliable that it used to be. Otherwise, I would finally choose JSP technology :-)
Thx in advance,
-G-

the graphic result will probably not be better with applets at all. They exist to make it far easier to port java programs to the net, but they are pretty horrible to use as a result (as you have experienced). Problem is, users don't care about what makes it tick, they just see them as slow and generally rubbish. I would use JSPs or servlets, which are a far better use of Java's power. However, you will need to do more work. They can both call out to external classes and beans, so you can reuse that way, but obviously you will need to have a think about how to restructure the I/O. You just have to look at skills demands to see whats good and whats not... just about every java job now asks for J2EE (servlet, JSP and other stuff) skills, but when was the last time you saw a job ask for applet skills?!

General questions about livecycle and forms

Hello everybody,
My company is currently researching new technologies for an infrastructural change in our B2B and CRM IT.
We saw the possibility to use adobe forms within SAP netweaver to - for example - give a salesman the opportunity to download customer data into a pdf file before he visits customers and then edit his pdf files offline when he is with the customers. The data would then automatically be transmitted from the pdf files to the database when he is online again.
Now we wondered if it's also possible to use this technology outside of the SAP environment and we found out about adobe livecycle.
Now my questions:
1) Are forms (like described above) an integrated part of livecycle?
2) Do you have to buy the whole livecycle package or is there also a possibility to just get the forms functionality?
3) Do you have to pay for every interactive form you create like it is done when you use it within SAP?
4) What hardware and software do I need to make interactive forms happen?
5) How much would licensing this technology be approximatelly. And how is it organzied? Do you pay for developer licenses, user licenses, or for every form?
Hope you can help me to get a better idea of this topic.
Regards,
Peter

1) Are forms (like described above) an integrated part of livecycle? <answer> Yes 2) Do you have to buy the whole livecycle package or is there also a possibility to just get the forms functionality? <answer> LiveCycle server is bought based on functionality and yes you can buy just the forms component 3) Do you have to pay for every interactive form you create like it is done when you use it within SAP? <answer> No that is an SAP thing only. Once you buy forms you can build and use as many as you like. 4) What hardware and software do I need to make interactive forms happen? <answer> You will need a server and an application server as well as a database. It does ship with a JBOss and mySQL server and depending on your usage you may find that is enough. 5) How much would licensing this technology be approximatelly. And how is it organzied? Do you pay for developer licenses, user licenses, or for every form? <answer> You will have to contact an Adobe sales rep to get appropriate pricing. Yes it is organized into developer licenses and production licenses.

Report Builder Question - OA AR Aging - and a general question

I'm sure this is the wrong forum for this question, but I thought there might be someone here who might be using Oracle Applications and Report Builder who'd be kind enough to help me out.
We've recently implemented Oracle Applications 11.5.10 and I have to use report builder to change the Accounts Receiveable Aging (7 bucket) to a 5 bucket report. I've already made some changes to the seeded "ARXAGMW.rdf" report, but I'm not a big Oracle Reports guy. I've stumbled through making some changes in various other reports. But this one is just plain nasty! :)
I was thinking that I could simply add buckets 6 & 7 to bucket 5, then just hide or delete the 6 & 7 buckets. But I'm not sure where to even start. Any help with this would GUARANTEE a Christmas or other holiday card this year! :)
I really want to keep this simple as possible, so any help would be very....helpful. :)
Oh, my general question is: Are there any resouces/books for Oracle Reports (Report Builder)? I feel so lost trying to modify existing reports, let alone creating new ones.
Thanks again!
Steve

Hi Steve,
I am working on the 7-bucket aging report and i want to add a new field in data model.
As the query is build dynamically, i have modified the function BUILD_CUSTOMER_SELECT to meet my requirements.
But the problem is that in the data model, the field is not present in my Grouping. and if I try to add the field in the Data Model query (Q_ Customer) section,
i get the following error: ORA-01789: query block has incorrect number of result columns.
The query is as shown below:

General question about iTunes Match and multiple libraries

Hello to everyone,
I have a general question about the iTunes Match service, which is available since yesterday in my country (Italy). Currently my library situation is the following:
Computer A (desktop, Windows 7): "big" iTunes library (about 20 GB), at the moment not associated with my Apple ID
Computer B (MacBook Air 2011): "small" iTunes library (about 5 GB), associated with my Apple ID
At the moment, both my iOS devices (iPhone 4 and iPad 2) are synchronized with the smaller library on the MacBook Air.
Question is as follows: should I subscribe to iTunes Match, would it be possible to upload the "big" library (provided I associate it with my Apple ID) to iCloud while keeping my devices synchronized with the "small" one?
Ideally, at the end of the day, the situation should be the following: both iOS devices with music from the small library + possibility of downloading songs from iCloud (coming from the big one). Is this possible?
Maybe the question sounds stupid, but I want to be sure about this before paying for the service.
Thanks a lot.

Yes, you could also associate your larger library with iTunes match if you associated your Apple ID with it. However any purchases in the library made from another Apple ID will not be matched with iTunes much.
If both libraries are part of iTunes match, then all your devices will see all of the content from both libraries, which content you choose to have on those devices and which you have accessible via iTunes match is entirely up to you.

Camileo charging problem (solved) and a general question!

Hi all!
First of all, I was going to ask for help as to why the Camileo S10 was not charging (the orange light wasn't flashing), and I'd seen a few people with similar problems.
The solution?
Give the contacts on the battery a clean.
The insulation sticker that comes on it must leave some kind of residue on it, and it's enough to prevent charging. Now it's flashing away happily :]
So my general question was, is it possible/advisable to use the camera on the mains?
Rather than constantly draining and charging the battery during long shoots, I'd prefer to just leave it plugged in!
Thanks very much in advance!
Paul

Hi
I think the battery handling is always the same no matter what product it is
From time to time the battery should be recalibrated.
This means that the battery should be discharged fully and after then you should charge it again until the battery would reach 100%
I do this with all my batteries; mobile phone battery, digi cam battery and notebook battery.

Update on Bioinformatics WIKI, scripting challenges, and a general question

I am waiting for my site to go on-line at Oak Ridge National Labs (USA, Tennessee). Should be another week or so, maybe less.
When that happens, you will see a veritable explosion of scripting challenges in my wiki (Emerging Technologies->Bioinformatics.)
One general question in preparation for these challenges.
There are a number of standard bioinformatic programs that can be run interactively via the web at various sites, e.g. "BLAST" and "STRIDE".
Although these can also be run locally, this requires that you download large databases and keep them updated.
So here's my question to the scripting experts:
Are scripting languages powerful enough to submit queries to web pages and then use regex's to parse the html that is returned?
Bill Mann has used PERL to do some of the required regex parsing, but there is a lot left to do, and, his stuff only works when a perl program is invoking a bioinformatic program locally, not interactively.
If so, we all can do some beautiful stuff together , if anyone is interested ...

...my wiki on...
There is by it's very nature no such thing as MY WIKI, except you run your own wiki project in an exclusive mode. Which were...well ... unusual.
Are scripting languages powerful enough to submit queries to web pages and then use regex's to parse the html that is returned?
Yes.

General questions about using webservices and xml as opposed to an oracle driver

Dear Experts; I have a general question which I have yet to test. Is it faster to use an ODBC driver to connect and retrieve data from an Oracle database than creating a .net webservices and using an XML to get the data for your web application. THank you

At some point in the architecture stack some component will need to access the database in order to get the information from the database. That component will need to use an Oracle client driver.

SAP CM25 which profile to use and why and some general questions

Hi there,
I have a few general questions, if you may share your thoughts on this.
In a manufacturing environment, is CM25 more used to finite schedule the work centers or labor or both ?
Is it a good idea to even finite schedule the planned orders or just production orders ? We want to create production orders 1 week ahead of the production schedule and planned orders gets created 3-4 weeks earlier than production order gets created.
The graphical tool seems to be slow sometimes when dispatching and doing some actions on the screen, has any one have any say on this. Should we need to have better computers on the floor for this to work ?
I have been trying my solutions using CM25 and not CM21 or CM27 using the profile SAPSFCG005, is there any other profile that I need to consider and other transactions to consider like CM21 or CM27 for certain purposes?
Thank you

Hello
In a manufacturing environment, is CM25 more used to finite schedule the work centers or labor or both ?
It can be used for both depend upon bottle neck resource whether machine or labour.
Is it a good idea to even finite schedule the planned orders or just production orders ? We want to create production orders 1 week ahead of the production schedule and planned orders gets created 3-4 weeks earlier than production order gets created.
Better it should be finite planning for planned order also you can use MRP with lead time scheduling.
The graphical tool seems to be slow sometimes when dispatching and doing some actions on the screen, has any one have any say on this. Should we need to have better computers on the floor for this to work ?
It depends upon the data load and selection,
Restrict the number of objects to be displayed, for example, select only a small number of work-centers/orders.
Customize the time profile (transaction OPD2) such that the database read period, the planning period and the evaluation period are as small as possible. As a result, fewer objects are read and displayed.
Refer KBA 2038780 - Tips for performance improvement on Capacity Leveling
If you want to process more orders, check whether a batch planning (planning in the background on transaction CM40) is possible.
I have been trying my solutions using CM25 and not CM21 or CM27 using the profile SAPSFCG005, is there any other profile that I need to consider and other transactions to consider like CM21 or CM27 for certain purposes?
It depends upon your requirements which transaction to use and which profile. You can customize your own profile also.

General Question about JRE - Versions and backward compatibility etc

Could someone maybe help me with this query?
I've got a group of network users who use a total of four java applications which I am told require different versions of the Java Runtime Environment to run.
Is it therefore possible to have muliple versions of the RTE installed on one user machine to make all applications work at once or is it simply a case of having to have only one version of the JRE.
I'm talking mainly about in house applications so I guess if some of them are incompatible with the latest JRE then the answer might be to find out what the problem is and fix the application so it works in the lates jre - or am I missing something?

Hello,
First of all, it is possible to keep several JRE installed in Windows. For example, my PC has JRE 1.3.1.8, 1.4.0.1, 1.4.2.6.
Second. A tecnology exists to cause a Windowst to run a specific JRE for a specific Java applet. Please see the text below.
HTML Applet Configuration
� The standard (Internet) method of calling Java Runtime when using a Java Applet is to use an Applet tag within the HTML file itself specifying the applet details (example below). This tries to attach itself to Microsoft Java Runtime registry CLSID as detailed above.
<applet code=Applet1.class width="200" height="200">
Your browser does not support the <code>applet</code> tag.
</applet>
� When the above call is made either, a) the applet will load in the Microsoft Java Runtime, b) the applet will load in a particular Sun Java Runtime as it�s being redirected or c) the applet won�t load at all as Microsoft Java Runtime isn�t installed and Sun Java isn�t set as default.
� The above can be uncontrolled as to what version of Java (if any) is actually used to launch an applet so have an alternative solution is to us the Object tag in place of the Applet tag. It�s only suitable for Internet Explorer in an internal, Intranet environment but should be ideal for us.
� By replacing the Applet HTML tag with the Object tag when loading an applet you can specify in the tag either to use the latest installed version of Sun Java or a specific version by putting it�s CLSID in the list. (example below.)
<OBJECT
classid="clsid:CAFEEFAC-0014-0002-0006-ABCDEFFEDCBB"
width="200" height="200">
<PARAM name="code" value="Applet1.class">
</OBJECT>
� The advantage in the above approach is we can install a specific version of Java, i.e. 1.4.2.06 that doesn�t redirect the Microsoft Java Runtime so won�t effect other applications, and we can be safe in the knowledge that even if we install a newer version of Java on a machine that has 1.4.2.06 we won�t have any backwards compatibility problems.
� The Object tag is an Internet Explorer only solution, but could be scaled, as to load a different version of Java you specify a different CLSID, whether that�s one of the versions of Sun Java or Microsoft Java or you can specify a CLSID that covers the latest installed version of Sun Java if you don�t want to tie the application to a specific version.
Further details on the use of the Applet and Object tags can be found on the Sun website below so they may be of use if the HTML code that calls the Java applet can be easily changed to support our requirements.
