• Taking MySql backup from my Java application

  - by dhiraj

  I am developing a Java application with MySql as the database. I have to dump the MySql database from my application periodically(let say every day at 10 a.m.) and I have written a batch (.bat) file for dumping the database. The batch file is working fine, but the problem is that it is asking for password each time during its execution. Is there any way to dump MySql database without prompting for password and achieve it from Java application periodically?

• Overload with different return type in java?

  - by nunos

  So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java? By the way, just for reference, is this possible in C++? Thanks.

• Which to learn first: Java/J2EE or .NET ?

  - by Eric Gustavson

  Is there an advantage to learning Java or .NET first? (ie. would the transition from J2EE to .NET be significantly easier than the reverse?)

• Java reference storage question

  - by aab

  In java, when you pass an object to a method as a parameter, it is actually passing a reference, or a pointer, to that object because objects in Java are references. Inside the function, it has a pointer to that object which is a location in memory. I am wondering where this pointer lives in memory? Is a new memory location created once inside the function to hold this reference?

• mongodb java driver - raw command?

  - by Scott

  Is it possible to execute raw commands as javascript through the Java driver for MongoDB? I'm tired of wrapping everything in Java objects using Rhino, and would happily sacrifice performance for the convenience of passing javascript directly through to the DB. If not, I can always use sleepymongoose or something, but I don't really want to add yet another language (python) to the stack at this point. Any insights are appreciated.
