Dear all,
I m building a web application from where i want to connect to orkut server,gets online friend list,scraps,send scraps.i want to use a java api for this feature.
Is there any technique available in Java for intercepting messages (method calls) like the method_missing technique in Ruby? This would allow coding decorators and proxies very
easily, like in Ruby:
:Client p:Proxy im:Implementation
------- ---------- -----------------
p.foo() -------> method_missing()
do_something
im.foo() ------------------> do_foo
p.bar() --------> method_missing()
do_something_more
im.bar() -------------------> do_bar
(Note: Proxy only has one method: method_missing())
What is the best way to capture a kill signal in java without using JNI. I did discover the sun.misc.Signal and the sun.misc.SignalHandler and the warning of the possibility of being removed in the future releases.
Would using JNI to call a c lib be the only option i have?
hey folks,
Can someone help me with this Java problem?
I want to write a method that takes two strings as arguments and returns true if each character (including space and punctuation) that appears in one string also appears in the other.
Thanks
Hi,
I want to create a Word or RTF file with a table of contents (with links to each section) from Java. From my understanding, iText & Apache POI do not support generating a table of contents. Some clients of the app still use older versions of Word, so I need a library that supports the older Word doc format. Does anyone know how I can do this?
Thanks,
Glen
Say your application is unresponsive and you cannot attach a debugger to it, as it rejects everything. All you have is a Linux Bash and process id. How would you investigate the issue? What tools would you use? My goal is to better my troubleshooting skills using Java.
This particular issue we had in production, on customer site.
Is there a way to get all possible values from a MySQL enum column?
The MySQL documentation says the MySQL enum type is returned as a Java String, so I basically would like a way to get all possible strings I can pass when querying a table with such an enum.
I couldn't immediately find anything when I was looking through the metadata returned for such a column, but since enum isn't standard SQL, I'm not sure it's even possible... any suggestions?
Hi,
I am getting the following error when deploying an application on JBoss 4.2.1
7:05:59,673 ERROR [Application Name]StandardWrapper.Throwable
java.lang.IllegalStateException: Application was not properly initialized at
startup, could not find Factory: javax.faces.context.FacesContextFactory
I browsed the net and I found many posts which suggested to add an entry in web.xml but that entry was already there. And all the required libraries are there in web-inf.
So any solutions anybody ?
Is it slower to iterate through a list in Java like this:
for (int i=0;i<list.size();i++) {
.. list.get(i)
}
as opposed to:
for (Object o: list) {
... o
}
hi,
I need the java code snippet for the below logic:
Following is a string and I need to validate the string based on the below condition :
"100 or 200 and 345 not 550 " - Valid string
"abc or 200 and 345 SAME ** 550 " - Not a Valid String
1 . the operands(eg 100,200 ..) should be positive numbers
2 . the operator should be and/or/not
Thx
I have a simple xml file and I want to remove everything before the first tag.
.....
item1
....
The following java code is not working:
String cleanxml = rawxml.replace("^[\\s\\S]+<item>", "");
What is the correct way to do this? And how do I address the non-greedy issue? Sorry I'm a C# programmer.
This question got me re-thinking about something that always bothered me:
Does Java need tuples?
Do you feel the lack of them in your day-to-day work? Do you think tuples would simplify otherwise complex data structures you find yourself implementing?
hello!
I need to extract the zipcode from file's line.
each line contains an adress and is formatted in a different way.
eg.
"Großen Haag 5c, DE-47559 Kranenburg"
or
"Lange Ruthe 7b, 55294 Bodenheim"
the zipcode is always a five digit number and sometimes follows "DE-".
I use Java.
Thanks a lot!
Hi there,
How would I be able to handle downloads using HttpResponse in Java? I made an HttpGet request to a specific site - the site returns the file to be downloaded. How can I handle this download? InputStream doesn't seem to be able to handle it (or maybe I'm using it the wrong way.)
This post is similar to this post, but not exactly, so I'm asking this question.
How does one go about, From a Java WebStart app:
launch a new browser window with a target URL?
bring an existing browser window into
focus with a target URL?
Is the solution OS/platform independent? Does it matter which browser you're talking to?
I just want that my program or method should run at specific date and time.
i have heard about Timer and TimerTask in java api. But don't know exactly how to use it.
Hi All ;
I want to make searching on my database with hibernate in Java, how can I do that?
Normally when I am using JDBC I wrote this code :
String Sql="select * from table1 where id like '"+jTextField1.getText()+"%'";
but I want to do that with hibernate database operation,
do I need to use session.load(..) ?
Thanks from now...
I find it curious that the most obvious way to create Date objects in Java has been deprecated and appears to have been "substituted" with not so obvious to use lenient calendar. So...
How do you check that a date given as a combination of day, month and year is a valid date? For instance a date 2008-02-31 (as in yyyy-mm-dd) would be invalid date.
Hi All
To build a java-based GUI using jsp and servlets, what are the different factors that go into selection of frameworks like AJAX, JSF, Struts 1/Struts 2 etc.
Also for each of the above pls throw some light on, what are the libraries, toolkits and IDE which are available?
Thanks.
Is there a way to get Class object from the type variable in Java generic class? Something like that:
public class Bar extends Foo<T> {
public Class getParameterClass() {
return T.class; // doesn't compile
}
}
This type information is available at compile time and therefore should not be affected by type erasure, so, theoretically, there should be a way to accomplish this. Does it exist?
Hi, everybody. I invoked shell command by Process class of java and it gave "stty: standard input: Invalid argument" no matter the command is right or wrong (normal output of shell command is shown too). If I run the shell command in shell, no such error message shows. I can't figure out why.
Thanks
Is there a way/tool to auto convert Java source code from using raw types to using generic types?
I have some legacy code with 677 references to raw types:
ArrayList 47
Vector 420
Hashtable 61
Enumeration 64
Class 7
Iterator 78
TOTAL 677
Now I could manually look through the code to infer the generic types and replace, but that is going to take a long time.
can any one give me the source code for mp3 streaming blackberry java application with play/pause, volume slider controls... with background too...
thanks in advance.
:)
