Do you know a tutorial how to create a CXF web service from existing Java code and embed it in Tomcat, and also generate a wsdl file so that any .NET system would be able to generate client code easily?
I miss that WSDL creation point in, for example this
http://www.ibm.com/developerworks/library/ws-pojo-springcxf/
tutorial. No wsdl file is generated. But still it should be present in my case to provide system interoperability.
I'm trying to encourage a best practice of not catching general exceptions in Java code. eg:
try {
...
} catch (Exception e) { // bad!
...
}
Is there a way to flag this as an error/warning in Eclipse?
I know PMD picks this up, but I'd rather avoid integrating it into everyone's build environment at the moment.
Hello all,
When running a thread in Android/Java:
public void run()
{
while (running)
{
if (moreTasksToExec())
{
task = getNextTask()
task.exec();
}
}
}
Is it OK to let it run and not using a semaphore to block while no work needs to be executed?
I am only using one thread, so I need no inter-thread synchronization.
Sorry I dont know the correct terminology to use but I have a 3x3 matrix like this
1 3 4
5 4 5
2 2 5
and I want get the highest score by picking a value from each row/column but I cant pick the same row or column more than once , so the answer in this case is
3 + 5 + 5 = 13 (row0,col1 + row1,col0 + row2,col2)
4 + 5 + 5 = 14 is not allowed because would have picked two values from col2
I'm using Java, and typically the matrix would be 15 by 15 in size.
Is there a name for what Im trying to do, and whats the algorithm
thanks Paul

Dear All,
I am new to MySql database. I've large table(ID,...). I select ID frequently with java code and.And that make a heavy load on transaction
select from tableName where ID=someID
notes:
1.Database could be 100,000 records
2.I can't cache result
3.ID is a primary key
4.I try to optimize time needed to return result from query.
Any ideas for optimization ?
thanks in advance
I'm trying to figure out how to enforce a 5 minute per post/action rule.
I'm developing a web application with Wicket in Java and I've got a session class which I was planning on using to keep track of these timers on a per-user basis. I wasn't planning on storing the timestamp in a database.
public boolean isAllowedToPost() {
if(null OR has 5 minutes passed since last post) {
// set the new timestamp
return true;
}
else
{
return false;
}
}
Hello,
How can I clone Array List but also clone its items in Java 1.5?
For example I have:
ArrayList<Dog> dogs = getDogs();
ArrayList<Dog> clonedList = ....something to do with dogs....
And I would expect that objects in clonedList are not the same as in dogs list.
Thanks for any answer!
When indenting java code with annotations, vim insists on indenting like this:
@Test
public void ...
I want the annotation to be in the same column as the method definition but I can't seem to find a way to tell vim to do that, except maybe using an indent expression but I'm not sure if I can use that together with regular cindent.
edit: The filetype plugin was already turned on I just got a bit confused about indenting plugins. The accepted answer may be a bit hackish but works for me as well.
In Python, I can do this:
>>> import string
>>> string.letters
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
Is there any way to do something similar in Clojure (apart from copying and pasting the above characters somewhere)? I looked through both the Clojure standard library and the java standard library and couldn't find it.
Simple example: we have string "Some sample string Of Text". And I want to filter out all stop words (i.e. "some" and "of") but I don't want to change letter case of other words which should be retained.
If letter case was unimportant I would do this:
str.toLowerCase().replaceAll ("a|the|of|some|any", "");
Is there an "ignore case" solution with regular expressions in java?
I have a xml document like this rootXMLDoc=<root></root> . I need to insert paramxmlDoc= <parameter par='1'>abc</parameter>. how to insert paramxmlDoc to rootXMLDoc in java.?
I am scrapping data from web site using my java application and want to display the result after parsing code of html page in a Text Area made in Swing.
Text like: hello <b>every</b>one should be displayed as: 'hello everyone' in text area.
Thanks!!
I have a Class<? extends Annotation> and tried calling newInstance() but Java yelled at me for the obvious reason that I can't instantiate an interface. But I know frameworks like EasyMock are perfectly capable of instantiating interfaces. What would it take to get a completely dumb Annotation instance out of my Class?
I'm having trouble with a JVM running an app, whose heap memory looks like a comb. It's constantly jumping from 1.5 GB to 3 GB and slowly deteriorating to higher values. I'm using G1 GC algorithm, but have no idea how to configure it.
I do not have access to the code of the app I'm running and, needless to say, it's a rather large app.
So, bottom line, does anyone know of a good guide to configure GC in Java?
What are the best practices for using Java's @Override annotation and why?
It seems like it would be overkill to mark every single overridden method with the @Override annotation. Are there certain programming situations that call for using the @Override and others that should never use the @Override?
Is there a method in JDK or apache commons to "pop" a list of elements from a java.util.List? I mean, remove the list of elements and return it, like this method:
public Collection pop(Collection elementsToPop, Collection elements) {
Collection popped = new ArrayList();
for (Object object : elementsToPop) {
if (elements.contains(object)) {
elements.remove(object);
popped.add(object);
}
}
return popped;
}
Hi all,
Most google results for sample questions/problems for java, results in a link directing to mock certification questions. Does anyone know where can i find sample problems for practice ?
Thanks
Hi guys.
First I want to say is that I am 37 years old and not from programmer background (actually from biology). And my question is should I start learning Java? I have coded in PHP and JavaScript for a year and a half. Every answer would be appreciated.
Thanks in advance
Bobi.
For example:
a) int [x][y][z]
vs
b) int[x*y*z]
Initially thought i'd go with a) for simplicity
I know that Java doesn't store arrays linearly in memory like C does. But what implications does this have for my program?
