Hi Sai,
Thanks for reporting that, I'll test it again and see what the issue could be.

Sai,
I found what's wrong!
This component requires a Java JDK installed, if you have this error this means that you are using a JRE, or that Talend is configured to use a JRE.
Verify what you Java installation is.

vgalopin,
I have the JDK installed on my client machine in the following path. I have also added the path under preferences -> java -> Installed JREs
I see that jdk path is checked here. I chose the type Standard VM while adding the new path.
C:\Program Files\Java\jdk1.6.0_25
Please let me know if i am missing anything. Do i need to install JDK on the Talend server as well.
Thanks,
Sai Krishna.

Sai,
In Preferences, click on Talend, and check that the Java Interpreter is corresponding to the right path.

vgalopin,
After adding the Java.exe path from jdk on the Java Interpreter, I am getting similar set of errors ( i have attached screen shot )
On the execution run screen i am getting the following message.
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
TalendString cannot be resolved

Hi
The dependency routines are missing, right click on the job name and select 'set up dependency routines' option to add the system routines.
Best regards

Something is definitely wrong. All the encryption classes come from the jdk, the fact that your studio cannot find them, even though you have configured it to use the jdk is not normal.
Could you do this for me:
- Select the tScramble component in your design
- On the bottom left, click on the Code Viewer tab to show the code for the tScramble component
- Click on the Down Arrow next to it and make sure "All" is selected.
- Copy the code displayed and paste it here
It will help me understand why it's working for me and not for you.

Hi,
Thanks for that. There's obviously issues in my component, I have issues on my side too. I'll try to find some time today to work on it and fix it.
I'll let you know once I release a fixed version.

Hello,

Have you been able to do any progress so far? I think that such a component would be a really nice thing to have.
(I have also tested the component as well and I encountered the exact same issues as saikrishna)

It's obviously been awhile, was this issue ever resolved?

Hello,
I don't know if it's the good explanation for the case problem but i see a similar problem after un copy / paste of the studio.
In this case, just recreate a new workspace and import your batchs. After that, the problem is solved.
Otherwise, you can also try to recreate a new workspace with an other JDK.
