I am using maven to build my project. I wanted to create assembly jar including some of the dependencies, so I wrote my custom assembly descriptor.


The problem is, It is creating jar having classes at directory structure like "Exporter-atlas2.1/<package name>/<class name>". For example, "Exporter-atlas2.1/ch/qos/logback/classic/util/EnvUtil.class". Thats why, it throws, ClassNotFoundException at the runtime. I was expecting classes to be present at "/<package name>/<class name>/",For eg. "ch/qos/logback/classic/util/EnvUtil.class".

I am trying to use slf4j and logback libraries for logging in my project. I want to do the configuration through code rather than through xml.

and afetrwards, I am catching localLoger in . and then using it for logging via . Idea about where I have got wrong it is not making the new file logFile.log, and printing log messages on screen.

I have build the TriggerBuilder object with cron expression and I am scheduling it for every 10 min. If I do a trigger.getStartTime() in a different thread/job set by trigger, will it give me the very start time or the time for which the particular job is scheduled at?

Was little curious to know, that can we build some plugins for netbeans and then sell them? Since netbeans is an open source, if we are supposed to do that?

As per my understanding, the difference between Synchronized method and Synchronized block is that in synchronized method...compiler doesn't allow any other thread to go in the method for a particular object...if some other thread is inside the same method for the same object but that object could be any object and in synchronized block..we specify that object for which the method call has to be synchronized

but if I try to run the following code,


which was expected also

but for the following code:


why the method is synchronized when the argument specified in the synchronized block is different from what is used in calling the method.

You will need to invent:

1. method for identifying files and relating the identity to:
2. parsing words or phrases or whatever you want to index on and:
3. creating a dictionary of words with links to the files they were found in.
(its called an inverted index)
4. creating a lookup mechanism to get from user input to the words in the index and eventually to the files.

Since my first try at this in 1979 (ah CPM, the good old days), I have found multiple solutions to the above - it is very educational.


Thank you sir,
could you also please tell me the good reference material for it(book or some published papers).
