Javax.crypto missing in my webdynpro project

Hello
I am trying to develop application which uses DES crypto function.
I have an example of code which should work but the problem is with the JCE crypto library it uses.
In normal java project I can import javax.crypto but in my web dynpro DC component I simply can't.
Is there any way to add this library?
Thanks for any help.

I found the solution myself and it was quiet simple.
Just open the properties of the project and add external JAR to java build path. The library I was seeking is located in program files/java/jre.../lib and its the jce.jar.
The other problem I am having with this is that when I try to build the development component, the jce.jar is removed from the build path and the previous error persists. It is strange because when I simply choose rebuild project and then deploy, everything works.

Import javax.crypto not found error

Hi,
I have just installed the JDK1.7 on a windows machine.
Whenever I try to compile my module, I get an error on the import javax.crypto line. It tells me that it can't the javax\Crypto\Cipher.class.
I have the jdk installed on d:\glassfish3 and am pointing the classpath to d:\glassfish3\jdk7 (also tried d:\glassfish3\jdk7\jre as well) with no luck.
Any help would be greatly appreciated.
Thanks,

Thanks. Maybe I should explain a little better.
I am using JBuilder 2006 to my IDE. This environment requires that you put in the path to the JRE/JDK.
I have uninstalled and downloaded the jdk again and this time i'm getting a strange error:
"test.java": cannot access javax.crypto.Cipher; bad class file: D:\Program Files\Java\jre7\lib\jce.jar\javax\crypto\Cipher.class, class file has wrong version 51.0, should be 49.0, Please remove or make sure it appears in the correct subdirectory of the classpath. at line 19, column 21
Now this is strange because i'm using the right library.
Is there something that I'm missing here?
Again, thanks for your help.

Javax.crypto reference in NW Dev Studio

Has anyone encountered and resolved the issue with trying to reference javax.crypto.* as an import with the Netweaver Development Studio?
i.e. Add a line like the following to your code:
Cipher c;
Then organise imports; and javax.cryto.cipher will be added but not found.
Thanks,
Matt

Simple really - Just needed to add JCE.jar reference to project (wasn't automatically done like the others). Oh well - now I can debug my provider problem.

Where the javax.crypto.* package located?

when I tried to complie my project with JBuilder 4,
it said that can not access the directory.
anyone can help? thanks a lot in advance.

Hi!
javax.crypto is a new package. I think you are to download jdk 1.4 and then tell JBuilder to use it (in JBuilder 5 it is done by Tools:Configure JDKs) instead of jdk that comes with JB(it is 1.3 for JB5 and probably 1.2 for JB4)

Where is javax.crypto?

I'm still fairly new to Java, so maybe i'm missing something here. I have the Java SDK 1.4.2 installed and I'm trying to create encrypt something using the javax.crypto package. I thought it came with the Java SDK but i dont seem to have it!
Anyone? help!

javax.crypto package will be present in j2sdk1.4.2/jre/lib/jce.jar

As i said there are No issues with ENCRYPTION and am getting an Encrypted file exactly of the same size as that of the original file and NOT as null bytes and Even am able to get a Decrypted file of again the same size of the Encrypted File but this time that data inside is in unreadable format.I ran your code EXACTLY* as posted and the contents of the file when viewed in a Hex editor was

Creating a WebDynpro Project in Studio

Hello,
I am involved in creating a WebDynpro project in Netweaver studio. I am using Get_Flight_List example project(I got it from the net).
Whole process of creating attributes and operations is performed.But,when i add teh relavent java code from the example, it gives compiler error.
Errors are :
1.getMessageManager() is undefined for the type IWDViewController,
2.bapiInput is not resolved and
3.wdGetFlightListComponentController() is undefined for type IPrivateFlightListView.
Kindly help me in resolving this issue/Suggest a way to create a simple WebDynpro project.

Hi
In case there are no errors in the code, CtrlShiftO and a ctrl+space wherever it is highlighting the error should resolve the problem.
bapiinput must be a object created in the code for the model class.
Have you created an object with this name.
In webdynpro section of SDN , you will have e-learning section which has detailed tutorials with sample projects.
Please look into it.<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/developerareas/webdynpro">WebDynpro Developer Area in SDN</a>

Using javax.crypto in oracle 10g

Hi,
I have a java stored procedure for oracle 10g (running jdk1.4) that
uses the javax.crypto package and the bouncy castle provider for RSA
decryption. Here is a snippet of the code in the procedure:
Security.addProvider(new
org.bouncycastle.jce.provider.BouncyCastleProvider());
Cipher rsaCipher = Cipher.getInstance("RSA");
RSAPrivateKey key = (RSAPrivateKey)
MSPrivKeytoJKey.getPrivateKey(aKey);
rsaCipher.init(Cipher.DECRYPT_MODE, key);
rsaCipher.doFinal(encryptedByteArray);
This works fine on my own machine running jdk1.4. However, when I load
my stored procedure into the database and run it, I get the following
exception after the line
Cipher rsaCipher = Cipher.getInstance("RSA");
tries to execute:
java.security.NoSuchAlgorithmException: Cannot find any provider
supporting RSA
I have tried the following (based on information gathered from various
forums):
- ran
loadjava -u username/pass@DB -v bcprov-jdk14-137.jar
- added the following line to java.security
security.provider.4=org.bouncycastle.jce.provider.BouncyCastleProvider
but i still get the same error.
I am reaching out desperately to all you experts for help :)

Hi,
Unfortunately, the Java VM only supports the basic JDK functionalities; you could try the Metalink Note 356123.1 which should work using BC library but this note only addresses AES.
Furthermore, you need the following two extra permissions:
exec dbms_java.grant_permission('SCOTT', 'SYS:java.security.SecurityPermission','putProviderProperty.BC', '' );
exec dbms_java.grant_permission( 'SCOTT', 'SYS:java.security.SecurityPermission','insertProvider.BC', '' );
Oboviously SCOTT would be changed to whichever schema you are using.

go to "DC Metadata" "used DC" , and "Properties" in context menu
for all you your components.
problematic component reference probable has check box "deploy time" checked.
remove that reference.
usually only "Build time" check box must be checked. try to do so.

One: Use the [ code ] tags. Please. It'll only help you get answers.
Two: encrypt() is returning the getBytes() of the result of Base64'ing the ciphertext. Bad. The whole POINT to Base64 is to produce Strings from byte[]'s. Don't use Base64 to produce a byte[]. Change encrypt() to return the byte[] directly.
Three: Given that encrypt() is returning the byte[] from the Base64 - decrypt() needs to be ready to UNDO that. It isn't. decrypt() assumes the byte[] it's getting is the ciphertext. That's not what you're giving to it. It's very, very unhappy.
Four: your main() isn't even handing decrypt() the (bogus) return from encrypt(). Your main() is asking decrypt() to decrypt your plaintext. That trick never works...
Five: your choice of variable names in your main() is...suboptimal. If you'd chosen names that reflected the purpose of the variable (things like, say, 'plaintext' and 'ciphertext'), some of this would have been obvious.

Can't add a webdynpro project to DTR...

Hi at all,
I've posted this already to WebDynpro but I don't know how to move it because it is maybe better to post it here.
I have created a local webDynpro application and as I got access to my DTR I added it to it. Everything was looking fine until I said that I want to remove the application from my client and created the project again.
On creating the WebDynpro project, the NWDS give me some error messages that some files are readonly!
(Web Dynpro Generation: Existing output file .../roadmap/RoadmapComponent.java is read-only!)
After that I removed the readonly flag in the windows explorer and rebuilded the project. But on the next checkin and sync from the DTR I got the same message.
I deleted the webdynpro project from the DTR and made sure that all files of my local copy were writable.
But still, if I create the project on the DTR, there are some files that are readonly if I sync them from there...
Does anyone know what the DTR is doing there, why it's automatically setting some files to readonly and how to solve that problem???
I read a lot in SDN how to add a project in the DTR, but all that doesn't solve my problem. I have no idea what I can do else.
I'm appreciated for answers.

Hi Roy,
usually you need all your source folders, whatever they are named. For a Par I would assume src.api, src.core and dist. for a regular Java project src (or src/packages).
If you are working with development component you must include the .dcdef file and the def folder. If the cfg contains files you should also add that.
As negative list: you should not include the bin folder (where NWDS/Eclipse puts generated classes), nor any folder starting with gen (e.g. gen_wdp for WebDynpro projects should not be checked in. The gen folder itself should never be checked in either, it contains the build results from a local DC build).

Problem when using javax.crypto.KeyGenerator in netbeans

This is my IDE information:
Product Version: NetBeans IDE 6.0.1 (Build 200801291616)
Java: 1.6.0_03; Java HotSpot(TM) Client VM 1.6.0_03-b05
System: Windows XP version 5.1 running on x86; Cp1252; en_US (nb)
I am trying to develop a Test jar file. I created some simple jar files and could upload it in mobile.
Now I want to implement some encryption. For that I started writing codes. But when trying to import javax.crypto.KeyGenerator class, netbeans is showing "cannot find symbol" error. I can use javax.crypto.Cipher/BadPaddingException/IllegalBlockSizeException/NoSuchPaddingException/spec/ShortBuffrException only. If i try to use any other class of javax.crypto, i get an error.
I am new to mobility.I downloaded netbean mobility package and Installed it.
Please provide some help.. thank you....
