How to Create trial version of my j2me application??

Hey..
could please anyone write a short note on safest way of creating a trial version of my j2me application?? like i want to limit the number of tries.. like say 25 tries..
are there any applications that do this.. or could u suggest good coding methods.. ??
thanks a lot!

Hi,
You can use the Record Store implementation to count the number of tries.
But if once the app is uninstalled then the record store is also lost.
If you want you can use the File Connection API to write to file system.
This asks for user permissions.
Regards,
Rakesh pachawa.yes.. this is the method im using.. & i dont want to access the File System directly.. cause i want maximum compatibility. I don't mind re-installing the application causing the trial to be re-started.. thats fine.
but i don't want someone to be able to crack the class files by taking out the code which checks the Record Store..
how are j2me applications normally cracked pls??

ummm...you test it using the UTL_FILE package.

How to create production version & Explain with procedure

how to create production version & Explain with procedure
Madan

Hi Madan,
Production Versions are used to describe the production process to be used for planned / production order.
Why is it required?
Suppose you have 2/3 production lines and 2/3 alternative BOMs to produce one Finished Goods.
How system will come to know which BOM and Routing to be used. This is done thru Prod.Version.
In production version we maintain the combination of BOM and routing.
Also it can be designed with lot size or validity period.
Go to MM02--->MRP4 / Work scheduling view -
> Prod.Version.
Enter the validity period and lot size. and the production version should be unlocked.
After entering the reqd. routing no. and BOM alternative , carry a check.
After getting the Green signals ,Continue.
Thus you have saved the prod. version.
Mass processing TCode- C223.
Hope it would clarify you the basic of production version.

How to create the exe files for java application

How to create the exe file for java application?
got any software to do that?
Thanks

In terms of converting java applications into exe files, there are 3 schools of thought:
1) Instead of converting it to an exe, convert it to a jar file. Jar files are more portable than exe files because they can be double-clicked on any operating system. The caveat is that a Java interpreter must be installed on the target computer for the double-clicking to work.
http://developer.java.sun.com/developer/Books/javaprogramming/JAR/
2) Create an exe launcher that, when double-clicked, attempts to find a Java interpreter on the local computer and launches the Java application. The exe file is still double-clickable but whether your java application runs depends on whether a Java interpretor is installed on the target computer.

http://www.rolemaker.dk/nonRoleMaker/javalauncher/
http://www.jelude.cjb.net/
http://thor.prohosting.com/~dfolly/java/index.html
3) Create an exe launcher that bundles a Java interpretor. Same as above but when the exe file is double-clicked, it searches for a Java interpreter and if one is not found, it installs one on the target computer. The caveat is that the exe file would have an overhead of 10 MB in size for the interpreter.
http://www.excelsior-usa.com/jet.html (evaluation version available)
4) Convert the Java application into a native exe file. The caveat is that if you use Swing for your GUI, it won't be converted. Also this option is still somewhat experimental.
Can't think of any free options right now.

How to create a Batch file for java application ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

Assuming you want to develop a batch application rather than actually just create a .bat file ..

HOw to create a Batch file for java application and whats the use of this ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.

How to create a new push button in application tool bar in GMGRANT thru BDT

Dear SAP Gurus -
We have a requirement in 'GMGRANT' transaction. We need to create a button in the application tool bar of 'GMGRANT' transaction. Once the button is activated, if the user clicks on the button then it will go to a new screen (external screen). User can input data in to the external sceeen and upon saving, the data will be stored in to a custom table and when user clicks on 'back ' button user should come back to the GMGRANT transaction.
Just wanted to know, how to create / activate a new button on application tool bar of GMGRANT transaction and what are the configuration and detail steps to achieve the same through BDT.
We went through a lot of documents on BDT but do not have a proper solution.
Could you please help.
Thanks in advance.

Atul Mohanty

hi,
You can find user-exits (menu exits) to add new menu item.
But, there is no possibility to add new buttons on application tool bar.

How to create Default Schema from within the application

Hi friends
I am creating users using the following within my application using this syntax
BEGIN
APEX_UTIL.CREATE_USER
(:P124_USER_ID, :P124_USER_NAME,:P124_USER_FIRST_NAME,:P124_USER_LAST_NAME,' ',:P124_USER_EMAIL_ID,'xxxx');
END;
The default workspace for the user is set as blanks. I would like to set it to be the default workspace as per the current logged in user.
Can you help me with the syntax for this
thank you in advance
Laxmi

Laxmi,
The subject of the post is "How to create Default Schema from within the application".
But your question asks how to set the "default workspace" for a newly created user.
Those are different questions and not the ones I think you need answered.
Let me answer this question "How can you set the default schema for an account when creating the account and set it to the same value used for the default schema attribute of the administrator account used to authenticate to the currently running application?".
In the apex_util.create_user call use named parameter notation and fetch the information about the currently logged-in user first, e.g.,declare
l_workspace               varchar2(256);
l_user_name               varchar2(256);
l_first_name              varchar2(256);
l_last_name               varchar2(256);
l_web_password            varchar2(256);
l_email_address           varchar2(256);
l_start_date              varchar2(256);
l_end_date                varchar2(256);
l_employee_id             varchar2(256);
l_allow_access_to_schemas varchar2(256);
l_person_type             varchar2(256);
l_default_schema          varchar2(256);
l_groups                  varchar2(256);
l_developer_role          varchar2(256);
l_description             varchar2(256);
begin
apex_util.fetch_user (
p_user_id                  => apex_util.get_current_user_id,
p_workspace                => l_workspace,
p_user_name                => l_user_name,
p_first_name               => l_first_name,
p_last_name                => l_last_name,
p_web_password             => l_web_password,
p_email_address            => l_email_address,
p_start_date               => l_start_date,
p_end_date                 => l_end_date,
p_employee_id              => l_employee_id,
p_allow_access_to_schemas => l_allow_access_to_schemas,
p_person_type              => l_person_type,
p_default_schema           => l_default_schema,
p_groups                   => l_groups,
p_developer_role           => l_developer_role,
p_description              => l_description);
apex_util.create_user(
p_user_id        => :P124_USER_ID,
p_user_name      => :P124_USER_NAME,
p_first_name     => :P124_USER_FIRST_NAME,
p_last_name      => :P124_USER_LAST_NAME,
p_email_address => :P124_USER_EMAIL_ID,
p_web_password   => 'xxxx',
p_default_schema => l_default_schema);

Have bought P.E.10; how convert my trial version to full version?

Have bought Photoshop Elements 10. Had trouble installing it. Forum advised downloading trial version, then converting that. Have downloaded trial version successfully. But how do I now convert to Full Version without buying what I've already bought (I have a disk, a serial number, the whole package)? Many, many thanks if someone can answer this!!

Dear Gautham K., et. al,
Ah, I was somehow doing both the trial version and the disk version at the same time. I entered that long serial number at one point. And I'm not getting a countdown of days left when I open my Photoshop Elements. So it looks like I might have inadvertently installed the full version--yay! (will know for certain when the 30 days are up if my Adobe doesn't go kaput). In this case, I feel like a dunce. But I'm a grateful dunce and thank you, thank you, thank you for this information!! Can't tell you how much people like me deeply appreciate such help. There's a special place in Heaven, etc….
RSA12
P.S. BTW, others installing a purchased Photoshop Elements on a new Mac Lion might note that they have to go through steps to get a Photoshop Elements Installer FIRST or the software won't load. None of the Adobe instructions told me that and that's partially how I stumbled into a kind of shaky limbo.
