Obfuscate program
Hi
i use jdev 11.1.1.7
Can i obfuscate java classes, beans and/or other source of project ? How ?
thanks
No, I don't work with such tools. I don't see why. There is no obfuscation which can't be undone. It's more a question how hard you try.
I don't know what you try to do or why you want to use obfuscation at all. Google for it and you find lots of discussions about this and how useful it really is.
You 2nd question: sure you can encrypt some files (property files or other reaources) within you application. However, as you have to decrypt the data before using it the algorithm used is easy to hack into.

Any easier way to obfuscate email links?
I don't want email links in my web site to draw spam, so I try to make them invisible to the spammers' web spiders. So far I just use a really simple method: the Obfuscator widget which converts the text into hex codes that all browsers display properly, but that have no @ sign to draw spam. Of course spammers will eventually get smart enough to beat this, but for now it's OK.
It's a pain though that each time I make any tiny change in my web site, iWeb republishes the whole thing and I have to go into the HTML files with TextWrangler and edit all the emails. I've made it a little easier by saving a copy of the obfuscated version in a text file to paste.
Has anyone found a simple way to automate this? Is there a handy program that will scan a website folder and fix all the email links for you before you publish?Thanks for this pointer. It looks like a really useful and flexible utility. It will be very easy to set it up for my simple edit.
I will mark the question answered once I get it working.
Of course it would be even better if iWeb had a preference to automatically obfuscate all mailto: links. That would be dead easy for them to implement, and ought to be the default. -
Hi,
does obfuscating jars in ant in windows not work? I have the following code & get the error that seems to be related to obfuscation.

C:\myProjects\sims\build.xml:383: Expecting class path separator ';' before 'Files\Java\jre1.5.0_09/lib/rt.jar' in argument number 1
can anyone help with this please?I ran into this same problem when using ProGuard 4.1 for Java obfuscation. The problem is that there is a space in the path to your JDK/JRE, for example: c:\Program Files\Java\jdk1.6.0_03. Because there is a space before the word "Files", it isn't working. The solution to to wrap quotes around that particular command-line argument. In ANT, I needed to use single-quotes (because double-quotes were already in use for the XML attribute) such as:
<java jar="proguard.jar" fork="true" timeout="30000">
<arg value="-libraryjars"/>
<arg value="'${java.home}/lib/rt.jar'"/> <!-- Notice both double and single quotes used on this line. -->
...rest of the arguments go here...
</java>
Alternatively, using ProGuard's custom ANT Task, it would look something like (notice the use of double-quotes around the rt.jar location):
<proguard>
-libraryjars "${java.home}/lib/rt.jar"
...rest of the arguments go here...
</proguard>
Anyways, I hope this helps you or anyone else who runs into the same problem. Both of these approaches have worked for me. -
Oneway Wrapping PL/SQL Programs
Hello,
I have wrapped my PL/SQL package successfully through wrap utility, but it can be easily unwrapped by some websites like 'http://www.codecrete.net/UnwrapIt' or unwrap mechanism.
I need one way encryption for my program. Please suggest if there is any alternative.
Thanks & Regards
Pritish
Edited by: 1004790 on Jun 6, 2013 6:11 AMNo computer program in any language can be encrypted in a way that prevents someone that owns the server on which the code is running from reversing that encryption. The code, after all, has to be sent to the CPU to be executed. You can find sites that unwrap PL/SQL just like you can find tools that will generate C source code for the Oracle executable or the Java source for whatever JAR file you'd like to consider.
The best you can do is to buy something like PFCLObfuscate that will obfuscate the code before calling the wrap utility (and calling the older version of the wrap utility which is a touch harder to unwrap and for which there are fewer online unwrapping tools). That requires money to buy the tool, though, and it will add complexity to your code management and deployment process since you have to maintain both a readable and an obfuscated version of the code and ensure that the right thing gets deployed and that no one inadvertently causes there to be differences between the two. And an attacker could still unwrap your code and still see exactly what it is doing, it would just be a bit harder to follow.

}question:
this works right
public void remove()
list.lock();
int line = 0;
try{
*while(record.size() < 1)*
range.await();
record.remove(line);
range.signalAll();
}catch(java.lang.InterruptedException e){
System.out.println("await interupted: "+e.getMessage());
}finally{
list.unlock();
}this is deadlock
*int list = 0;*
*while((list = record.size)<1) was screwing things up because of the assignment*record is ArrayList of strings. when better to use Vector instead of ArrayList? i notice no differnce and i use threads
initially I thought record.size was being evaluated and before could be assigned to list, time slice ran out. this could not be case because I use ReentrantLock (list) to lock it.

The system is OSX10.5.8 Leopard on a 2009 imac. A new system was installed from the installation disks and the original system saved to a folder.
I need to use my Adobe programs, rescue my email, i-tunes and iphoto data. The disk utility indicates that my Time Machine back-up disk is damaged and I don't want to take a risk of having Time Machine erase my hard drive and try to reinstall the exact system existing at the time of the crash. There was over 650 gb of stored files that I was copying and removing from the drive at the time it crashed. The total size of the original system file is still about 650 Gb.
I would prefer to go back in Time Machine and only rescue the programs as most of the files have been copied to external hard drives, but I can't access the back-up hard drive from the new version of the Time Machine. Or by I don't want the Time Mchine to start copying the new operating system which would include all the data in the old system file. Time Machine was working fine at the time of the crash.No, the disk was backed up with time machine a few hours prior to the crash. I was unable to open the computer when I tried to restart it- got a grey screen with the spinning disk- after a few minutes the screen would go black and would reboot continuously, but not load any images or programs. I started the computer from the 10.5.4 installation disks and checked both the time machine external hard drive and the Imac internal drive with the disk utilities. Both showed as damaged --the internal drive and permissions were repaired, but the external drive (time machine back-up) was damaged and not repairable by disk utilities. I don't believe that the external drive for Time Machine was connected to the computer at the time of the crash as I was copying files to a different hard drive drive. And I was not having any problems with the TM back-up drive prior to the crash.
I accessed the Imac internal disk by firewire (as a target disk) and copied as many data files as I had room for on my external hard drives available. And I deleted quite a few files from the imac internal drive (mostly just jpegs, duplicate tifs, etc--nothing that was used by i-photos, i-tunes or the Mail program).
Then I installed a new OSX10.5.4 system from the installation disk and the old system was moved to a folder on the hard drive. I previousy had had the option to reinstall the complete system from Time Machine when I connected that drive and booted with the installation disks with the C key depressed. But it didn't seem like a good option because I was unsure of the condition of that external disk and whether it would be able to reinstall my data correctly, once it had erased my internal hard drive.
I'm considering buying some new external hard drives and backing up the present system to time Machine (so I'll still have my old data in the old system folder). And then I would try using the old Time Machine back-up to try to reinstall the sytem previous to the crash. That back-up would reinstall about 700gb of data and operating software and programs which sounds like a lengthy back-up. Since I have never used Time Machine to do a full reinstallation (I've only used it for individual files), I'm reluctant to do anything rash.
I'm a professional designer (with a deadline) but I can still use my Illustrator and Photoshop by opening them from the old system folder and saving the files to an external drive. So it's not neccessary to do anything hasty except to delete some of the excess art and document files that were causing the computer to run slowly and the Adobe programs to crash when I tried to save my work. I have quite a few books on tape in the i-tumes folder which is probably talking up tons of space but I don't where the i-tunes files live.
Thanks for any help. Peggy

Error: "Could not complete your request because of a program error" (photoshop CS2 9.0.2 on MAC OSX
Today I started my program (photoshop CS2 9.0.2) and opened a JPG file. When I went to print the file the program crashed and closed. When I restarted the program and went to open the file I got this error message, "Could not complete your request because of a program error".
I have tried several different file types/sizes and all result in the same error message since the program crashed. It will not open any file I try to open. As I indicated above I am using Photoshop CS2 9.0.2 it is on a MAC with OSX 10.4.11.
I called Adobe and the Rep directed me to Tech Note 331307 and told me to Re-create the Photoshop preferences files. Which I did and restarted the program, but when I tried to open a file (any file) I still get the same error message so it doesn't appear to be the preferences.
Does anyone have any info as to what the problem may be and how to correct it.
ThanksThanks for the response. OK... This is the first day I have been able to get back to the problem.
My system I am running Photoshop on is a Power Mac G4, AGP Graphics ATY Rage 128Pro chip set 16MB VRAM LCD 1280x1024 32-bit color, 500MHz, 1.75GB of memory, 1 MB L2 Cache, 100 MHz Bus Speed. I had installed the latest security update and repaired the permissions the day the problem started.
Now to day I started the system and went in and created a Guest Account. I logged into the guest account and started Photoshop. Low and behold it worked just fine. So I logged out of guest and logged into my main user account And started Photoshop. Wouldn't you know it.... It works just fine. I can open any file I want with now problems.
I got to thinking after I had done all of this that I wished I had tried to open a file in Photoshop today prior to creating the guest account to see if it still had the problem in my main user account.
I did not change anything else on the system and all seems to work fine now. So at his point I am really not sure what the problem was.
Again thanks for taking the time to respond to this issue. -
Photoshop CS2 (program error msg)... Help please!!
I have installed the full creative suite 2 on my new iMac. everything works fine except photoshop?!!?
Illustrator works great, In-Design works great, But when i try to open a file or create a new page in PS it tells me "Could not create document because of a program error"???? ***?
I had a previous version of CS and it worked fine for one day, then that started happening. I installed the CS2 trial version, and it would still give me the same error msg. I erased everything and installed the new CS2 (photoshop, illustrator , in-design and acrobat). It still gives me the same darn msg.???
Any help would be greatly appreciated!
thanksSee the Adobe Knowledge Base document"Error 'Could not complete your request...' or 'Could not create a new document...' (Photoshop CS2 on Mac OS X v10.4)"
I suggest whenever you have problems with third-party applications, the first place to start troubleshooting is with the application's documentation, then vendor's web site. Usually their sites have FAQs, lists of known bugs, or application-specific forums similar to these Discussions. Sometimes, unlike the Apple Discussions, the questions are even answered by employees of the vendor.

PhotoShop CS2 "Program Error" when printing
I am posting this to the Adobe Forums as well, but thought someone here might have some ideas. am having an intermittent problem printing from PhotoShop CS2 to an Epson 9800. When printing large files (200 MB average) to the Epson, PhotoShop will spool the job, taking about 50% longer than normal, and when complete, displays the following message..."The file XXXX.tif could not be printed because of a program error" No job ever gets to the print que. This happens about 80% of the time when printing. Quitting and restarting PhotoShop generally fixes the problem, and the file can be printed from another computer without issue, so this is not file specific. I have 8GB of RAM installed and PhotoShop running under 100% available memory, cache level at 8, with a dedicated 180GB scratch disk. Memory should NOT be the problem, though I do often have the full layered version of the file open in the background (I am printing from a flattened copy. I have observed that the problem is less likely to occur if no other files are open. I have a second G5 with the exact same software setup (OS, Print Driver and PhotoShop down to the decimal version #) that works perfectly every time. I have run all of the System utilities (Repair Permissions, FSCK, etc), reset the OSX printing system, reset PS preferences, trashed and re installed CS, as well as the Epson printer driver, all with no success. Any other trouble shooting ideas would be greatly appreciated. I would love to avoid a System reinstall.

KABA connection issue - program not registered
I am trying to troubleshoot a connection error between SAP and KABA. I have the RFC created in SAP and when I test the connection I get a program not registered. The KABA "amsproc" service on the KABA side has been restarted, we have occasionally received a password locked message in the SAP system log after restarting the KABA service (I believe this means SAP and KABA are communicating). We have since reset the password, but we can not successfully test the RFC and when attempting to send IDOC's out we get the program not registered error. Is there something on the SAP side that needs to be done to register the program or is starting the service on the KABA side going to register the program with SAP? Any assistance would be appreciated.
Hi,
In Central Management Console ie, Admin application of BOE, you need to configure the BW system. Use the below URL,
http://<serverhostname>:<port>/CmcApp
After logging in Select the Authentication and SAP as authentication type. Regarding how to configure, follow the configuration steps mentioned in the below article:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a00ee3b2-5283-2b10-f1bf-8c6413e0898f
Once you import the roles with the above configuration, the user with which you are validating the RFC connection will be imported in the BOE.
Now, verify the RFC in the BW system.
Regards,
Noor. -

All other programs work, but with Photoshop it says that it "Could not open a scratch file because the file is locked, you do not have necessary access permissions, or another program is using the file. Use the 'Properties' command in the Windows Explorer to unlock the file." Then I select "OK" and the next message comes up "Could not initialize Photoshop because the file is locked, you do not have the necessary permissions, or another program is using the file. Use the 'Properties' command in the Windows Explorer to unlock this file. I installed all of the programs on the same day from a CD. I need this fixed immediately.
I am not interested in switching to Creative Cloud, so don't even suggest it. I spoke to Mashmi (or something to that effect) on the "Support" Chat and there was absolutely no support. Useless actually.
Thanks in advance.Could not open a scratch file because the file is locked or you do not have the necessary access privileges. (…) | Mylen…
