It looks like you are reusing jobCtrlExample between method calls. if you do that, then you need to clear the previous conditions before you set new conditions. Probably adding this line will fix it:
jobCtrlExample.clear();
It would be better to create a new example class for every method.

Talend: How to get instance of a component in tjava

I want ask if there is way to get an instance of a component if a job (ex:tmap, tmysqlinput) in tjava code and then manipulate it manually using code?
Thank you
Very hazardous. Looking at the generated Java code will give you some answers (I think so).
In fact, accessing to some objects properties is possible (there is blogs and articles about this) but changing anything seems to be dangerous (IMHO).

Can I use Eclipse templates to insert methods and also call them?

I'm doing some competitions on a website called topcoder.com where the objective is to solve algorithmic problems. I'm using Eclipse for this purpose, and I code in Java, it would be help me to have some predefined templates or macros that I can use for common coding tasks. For example I would like to write methods to be able to find the max value in and int[] array, or the longest sequence in an int[] array, and so on (there should be quite many of these). Note I can't write these methods as libraries because as part of the competition I need to submit everything in one file.
Therefore ideally, I would like to have some shortcut available to generate code both as a method and as a calling statement at once. Any ideas if this is possible?
Sure you can - I think that's a nifty way to auto-insert boilerplate or helper code. To the point of commenters, you probably want to group the code as a helper class, but the general idea sounds good to me:
You can see it listed in your available templates:
Then as you code your solution, you can Control+Space, type the first few characters of the name you gave your template, and you can preview it:
And then you can insert it. Be sure if you use a class structure to position it as an inner class:
Lastly - if you want to have a template inserts a call to method from a template, I think you would just use two templates. One like shown above (to print the helper code) and another that might look like this, which calls a util method and drops the cursor after it (or between the parentheses if you'd like, etc):
MyUtils.myUtilMethod1();${cursor}

How to use CTTypesetterSuggestClusterBreak in Core Text

I am having trouble in using CTTypesetterSuggestClusterBreak function of CTTypeSetterRef class. I want to use this method to get closest word boundry near an index. I am having difficult in the implementationof this method, i.e how and where this method must be used.
I have been banging my head over this but with no success yet. If anyone can help me in using this method I would be very greatful.
Thanx in advance
I'm not sure CoreText is appropriate for this task; it sounds like you should investigate CFStringTokenizer instead.

ASTNodes And Views

I would like to know if there is a function that when i give it an ASTNode object (the ASTNode can be a class, method or a field in a CompilationUnit) as an argument it can show this object in a view (Tree view or Table view). If there isn't any such function, is there another way or workaround of doing it?
Thanks for your help.
You may be able to use the ASTView plugin
It's not clear if you are referring to Java or just something else. I'm assuming you need a Java tool. I'm not sure what exactly you expect to see in the "view".
Do check out nWire. It may be what you are looking for. Given any component in your code (like Class, field, etc.) it can show all possible associations to other components.
