Hi is there any tool available in Java world that will parse/read a source file and pull SQL statements out in to a text file. This is a complex task given that you can write SQL statements in different fashion within the source (ex: using + sign or using .append()) or even conditional building of SQL.
I'm looking for some simple tasks like listing all the running process of a user, or kill a particular process by pid etc. Basic unix process management from Java. Is there a library out there that is relatively mature and documented? I could run a external command from the JVM and then parse the standard output/error but that seems like a lot of work and not robust at all. Any suggestions?
Java does not have concept of operator overloading.
Still + operator behaves as addition operator with numbers and concatenate operator with strings. This is similar to the operator overloading behavior.
Please suggest.
Frustrated in finding the .jar -balls like google collections or "package org.apache.commons.io;". Is there some utility to get them fast like the style-"apt-get source app"? "get-java-jar-ball-3rd source apache commons"?
In Java, an array IS AN Object. My question is... is an Object constructor called when new arrays is being created? We would like to use this fact to instrument Object constructor with some extra bytecode which checks length of array being constructed. Would that work?
As far as I can see the key advantage of dynamic languages like Ruby or Python over Java/Scala/C# etc is "hot" applying of your changes to source code to the running application. What are the frameworks for JVM or .NET that support the same workflow - apply changes to configuration and source code on the fly? Can they also watch changes to custom configurations and notify application?
Note: Frameworks for dynamic languages on JVM/.NET like Grails or Compojure are out of scope here.

I have multiple Java projects in Eclipse. I would like to reuse some classes in my new project from my old project. What is the best way to do that in Eclipse?
I.e. is it possible to add another "project folder" to the build-path for my new project?
Is this possible in Java: Map<SomeObject, Map<SomeOtherObject>>? I'm trying Map<Integer, Map<String>> am getting an
"Incorrect number of arguments for
type Map; it cannot be
parameterized with arguments "
error.
I am a Java EE developer working mainly with JSPs, Servlets, and frameworks like Spring.
Will learning PHP be a wise decision ?
What would PHP offer me ?
You launch a java program from a console (maybe using a .bat script).
I don't want the console to remain visible, I want to hide it.
Is there a simple way to do this ? Without JNI ?
Thanks.
I want to write a plug-in which tracks the updates to a text file and stores them in a separate file.
Should I first write a simple java program which does this and then try to convert it into a plug-in?
Is it possible to use a for-each loop in Java and somehow still get the index of the iteration?
for (Object obj : ListOfObject) {
// I want to know the index of obj!
}
Hello,
I have a problem. I need to host many (tens, hundreds) of small identical JAVA web applications that have different loads during one time. I want to use Glassfish V3. Do I need to use a load balancer and clusters or something else? Advise where can I find information about similar problems and their solutions...
Best regards,
Alexey.
Lazy programmer alert. :)
Cassandra stores column values as bytes (Java example). Specifying a LongType comparator compares those bytes as a long. I want the value of a long into a Cassandra-friendly byte[]. How? I poked around for awhile. I think you people can help me faster.
We use socket.send(packet) function in java to send a "packet" to a given port.
My problem is that i have to send a packet to a shutdown system using UDP protocol.
The problem with send() function is that first it verifies whether the host IP is
multicast or not. Now my local area network is of broadcast type. So i am having
problem is using this function.
can anyone please give me a way ?
Are they same ?
