Security : certifying the source code

Is it possible to certify the source code (.swf) in a
flash/flex application (digital signatures, certificates...)?

Hi,
I have an app that is in a jar file with the .class
files (so no source code).
I'm wondering how difficult it is to attain the
source code from these .class files in my jar?
Looking through the contents of the .class files it
seems there is a large amount of readable text. For
example I see method names, variables, etc.
This leads me to believe these jars are not secure.
What is a better way?
Thanks!
Edit:
Looking around, I've noticed many java decompilers
and Sun even supports a dissembler - javap. I think
this is not cool, haha.
What way can I protect my code? To me, the value of
java just went way down due to the ease at attaining
source code (based on what I read in the past hour or
so. I have yet to try it myself). I wonder if this
impacts companies reasons not to use java?All intellectual property stored in electronic form is vulnerable. Not just Java bytecode. You can use tools called obfuscators to make decompiling more difficult, which is usually good enough. The truth is, no matter how great you think your code is, it's of a lot less interest to others than you actually think. Unless you've got a particularly sexy argorithm or something, it's not really worth worrying too much about
All you can do is make it more difficult for people to crack things, never prevent it. True of all languages, all electronic media

Edit 2:
I heard that there may be a way to make the jar closed, so you can't say, use winrar, to extract the class files. Does anyone know anything about this?

How can one encrypt the source code of a given web page(html, jsp, etc.) ?

Good Day! I'm just having a hard time of thinking how to encrypt the source code of a given web page(html, jsp, etc.) without affecting how it is previewed in an Internet Browser. What I plan is to disable the capabilities of some malicious Internet users of copying the source codes of my web pages by using the "View Source" option of Internet Explorer and the equivalent function in Netscape Navigator. Please somebody help me in this matter (I'm planning to use an IDEA algorithm using JCE)....
It would be big help if a running code is supplied.
Thank you very much in advance.
God Bless!!!

don't know theses softs. What i know about encrypted web pages, is that you need a secure socket connection (https).
Your web page will be ciphered, send to the user, and decipher by the browser with the signature file associated to your https connexion.
It isn't possible to encrypt your page directly, and then decrypt them when requested.
For the download time, only the server is responsible for this.
if it is overloaded, then it will slow down its upload.
Maybe you use some encryption method that require a lot of CPU time.
For summary : you can only cipher the pipe transport, but not the transported pages.
Good luck in your search.

Procedures/packages security. Hide source code?

Hi.
I was wondering if it is possible to hide the source code of a procedure for a user or avoid him to recreate it, but let him to execute it.
Im doing a sandbox procedure who edit and run an external job. It works fine but I see a bunch of security holes. If any DB user who can execute that procedure can edit it too, they could run any shell command by changing the external job attributes. I could use credentials (11.2.0.2) and somehow limit the system user to specific commands but I want to fix the security hole by limiting the DB user instead limiting system user.
This is the external job
BEGIN
DBMS_SCHEDULER.CREATE_JOB(
job_name => 'test',
job_type => 'EXECUTABLE',
job_action => '/bin/sh',
number_of_arguments => 2
DBMS_SCHEDULER.SET_JOB_ARGUMENT_VALUE (
job_name => 'test',
argument_position => 1,
argument_value => '-c'
DBMS_SCHEDULER.SET_JOB_ARGUMENT_VALUE (
job_name => 'test',
argument_position => 2,
argument_value => '/bin/date>>/tmp/date.log'
END;
/ And then, the procedure.
CREATE OR REPLACE PROCEDURE TEST_DATE_FILE ( new_file IN varchar2 )
IS BEGIN
DBMS_SCHEDULER.SET_JOB_ARGUMENT_VALUE (
job_name => 'test',
argument_position => 2,
argument_value => '/bin/date>>/tmp/' || new_file
DBMS_SCHEDULER.RUN_JOB(
job_name => 'test',
use_current_session => TRUE
END;
SQL> conn scott/tiger
Conectado.
SQL> exec TEST_DATE_FILE('newfile.log');
Procedimiento PL/SQL terminado correctamente.
SQL> CREATE OR REPLACE PROCEDURE SYS.TEST_DATE_FILE ( new_file IN varchar2 )
2 IS BEGIN
3 DBMS_SCHEDULER.SET_JOB_ARGUMENT_VALUE (
4 job_name => 'test',
5 argument_position => 2,
6 argument_value => '/bin/rm -rf /tmp/*'
7 );
8
9 DBMS_SCHEDULER.RUN_JOB(
10 job_name => 'test',
11 use_current_session => TRUE
12 );
13 END;
14 /
Procedimiento creado.
SQL> exec TEST_DATE_FILE ('');
Procedimiento PL/SQL terminado correctamente.
It is possible to hide the source code of the procedure who edits and run the external procedure?
There is any workaround or any idea of how can I prevent this?

I am running 10.6.8 and using iweb for my web site. After several SEO analysis they all indicate I need H1-6 header tags. After looking at the source code I see there are none in iweb. Is it necessary to add? If so, how do I add H Tags to iweb.

I am running 10.6.8 and using iweb for my web site. After several SEO analysis they all indicate I need H1-6 header tags. After looking at the source code I see there are none in iweb. Are they necessary to add? Why would one add these tags and how do I add H Tags to iweb? And are there examples to look at? I am slowly learning about simple web design and assumed that iweb was stand alone without having to write code. Is this one of the reasons iweb is no longer supported? Thanks for looking at this!

A simple text page like this:
Heading
    sub heading
          text paragraph ....
Is traditionally represented by html tags like:
<h1>Heading</h1>
     <h2>sub heading</h2>
          <p>text paragraph ... </p>
I would guess that the use of h1-h6 tags helps search engines to understand the structure of a page as the tags imply a certain structure.
This can be compared to more generic tags like <div> that could represent any kind of content - and may be what iWeb uses (you'll have to check yourself).
I would generally recommend that you use some kind of up to date blog/site building tool, perhaps Wordpress or Squarespace (I haven't used either one myself) that support current web technologies - this should reduce your SEO issues and make it easier to properly support mobile/tablet users.

How to get the source code in PAR file

Hi All,
I used the PAR migration tool to migrate from PAR to EAR file. When I imported the EAR into NWDS 7.3, I was just able to see the structure and jsp files and could not find the java source code files. I would requires the java source code to make modifications so that deprecated APIs can be replaced and to also make the code compatible with JDK 1.6.
I think the original 7.0 PAR file itself does not contain the source code. I decided to use the "Include source code" option when exporting the 7.0 PAR.
I have the portal application DC project in my NWDS 7.0. However, when I try to export the PAR file using Export --> PAR File -- > Next... I am unable to select any project from the list. The list appears blank with disabled Next & Finish buttons.
I also noticed that in the portal DC application structure, there is a .sda file under /gen/default/deploy. Also there is no PAR folder under /gen/default/public.
How do I include the source in the PAR file so that I can edit the same after migrating to EAR format ?
Regards,
Melwyn

DC and PAR/EAR stuff are different formats, SC/DC is an archive type used by NWDI, if I got it right.
How do I go about generating the PAR file (with source) ?
In fact through including the seources while creating the PAR/EAR in NWDS, but: no need to do that, you can also depack SDA (rename it to zip). If you wanna just see the Java sources you will find them there, otherwise decompile as Vijay already sad.
cheers

Where is the source codes in the project

Help! NetBeans 6.5 Compile.
Old man trying to learn Java and tools provided by SUN.
I down loaded all those swing demos. I throw 3 demos into NB-6.5 to compile with existing source. When I start building got the message says compiled class file in the ?build? folder. Recommended to delete. If I clicked ?yes? or ?ignore?, it compiled and ran OK.
One of my problem is, I like the source codes in the edit window and another one is I can not find my source in any folder in the project..
Project folder :
E:\NbProj\NbProj-1
\NbProj-2
\Nb/Proj-3
Swing Demo source
E:\DnLd\DemoZips
\Source
\demo.java-1
\demo.java-2
\demo.java-3
Is it because of my setup?
How can I get source codes into NB so I can learn NB and provided tools by editing compiling.
Appreciate for any education to an old man.

JLundan,
I want to thank you for responding to the thread I started on the forum at java.sun.com. Your solution to my problem of needing to print the code of the html pages that the file I included generates was just what I was looking for. However, I have some further questions to ask, if you don't mind. To clarify my task I should say that your rephrasing of the problem is accurate: "You wan't to display the contents of the HTML file that the web server produces in response of client's request?"
Yes, this is what I need to do, but also it needs to display the source code of that html file that the server produces in response to the client's request. Also, in this case, I am the client requesting that the server return some html file, and I'm not sure where the server is. But the webserver.java file that I shared on the forum is on my local machine. I was wondering if I could modify this webserver.java file at my home so that any html file the server returns to me would automatically display the source code. This is a school project of mine and I am stuck on this one thing here.
Further, where would I put the "foo.html" file so it can be written to?
FileOuputStream fos = new FileOutputStream("foo.html");
fos.write(bytes);
fos.close();
Thanks so much for your help. I look forward to your response, at your convenience.
Regards

ABAP WD, Read the source code of a html page

Hi all,
I have the URL link of .jsp page and I want to get the source code generated by this page to extract some data for my web dynpro.
How do i solve this?
Thanks

Hi Antonio,
not sure if i understand the question properly.
You want to read html content of http site rendered via jsp.
You can use cl_http_client
to write a simple http client tool.
This tool opens the page. The html content is available to this class.
You can extract the content here.
See the attribute 'response' after making a call.
regards
Phil.

Is there any differnce between the Numeric Limit Test source code from TestStand 3.0 to TestStand 3.1? How to get the source code for the Numric Limit Test for both the versions?

I need to know the differnece between the Numeric Limit Test between the TestStand version 3.0 to 3.1. If there is any differnec in the source code how to find it out? If somebody has the code can you share it?
Thanks,
Jeyan

Hi,
I don't believe there are any differences between the two versions. But you can check the source code for the Numeric Limit Test in TestStand\Components\NI\StepTypes\CommonSubsteps. But the main part of the step is the Code Module and this bit the users supplies this.
What has prompted this question?

If I Use JavaFX to Create a Game Do I Have to Release the Source Code?

Hello,
I've asked this question before, but I just thought I would try it again now
that version 1.0 is out.
If I Use JavaFX to Create a Game Do I Have to Release the Source Code?
Thanx in advance.

Could you please point me to a resource describing "the JavaFX Runtime license"? I'm trying to find answers to the following questions:
1. I'd like to use Scenario.jar from the JavaFX project in a desktop app that is not using Webstart and is not an applet. Will I be able to ship the jar with my software?
2. Can JavaFX applications be distributed as commercial software in the absence of a Web connection?
What's not clear to me is which is the real license for Scenario.jar (as shipped with JavaFX). Is it the one in openjfx-compiler's trunk, or the one that comes with the JavaFX SDK (which is very vague about redistribution)?

I Need Help to Access The Source Code From A Form to Know the Calculation Formula

Hi,
I Need Help to Access The Source Code From A Form to Know the Calculation Formula. The application is a windows form application that is linked to SQL Server 2008. In one of the application forms it generates an invoice and does some calculations. I just
need to know where behind that form is the code that's doing the calculations to generate the invoice, I just need to get into the formula that's doing these calculations.
Thank you so much.

Hi,
Thanks for the reply. This is a view and [AmountDue] is supposed to be [CurrentDueAmount] + [PastDueAmount] - [PaidAmount]. The view is not calculating [PaidAmount] right . Below is the complete code of the view. Do you see anything wrong in the code ?
Thanks.
