Could anyone tell me the difference between library and native library in terms of java? I found the word "native library" in the following line:
Type 1 - drivers that implement the
JDBC API as a mapping to another data
access API, such as ODBC. Drivers of
this type are generally dependent on a
native library, which limits their
portability. The JDBC-ODBC Bridge
driver is an example of a Type 1
driver.
which you can found here
I am very new to programming, so please bear with me, and apologies in advance if at first I dont make sense...!
I am doing an undergrad programming project, and need to make some databases within a Java program. I am using eclipse (galilo) to write my program. I have downloaded a connector/J, but havent the foggiest how i should use it!
Anyone out there able to give me a step by step approach?!
Many thanks!
JFace Databinding doesn't support generics, so it isn't particularly type-safe. And apparently it never will, since they wish to preserve Java 1.3 support.
JGoodies supports generics since 2.0.0. Has anyone ported JGoodies 2 to SWT/JFace? Or is there another library which allows both?
We have a very strange problem in out application, all of a sudden we started noticing upside down question marks being saved along with other text typed in to the fields on the screen. These upside down question marks were not originally entered by the users and it is unclear where they come from. We are using Oracle 10g with java.
And this is happening, even when no data is copied from Microsoft Word

In the above image, HTTP request sends something to Dispatcher Servlet. My Question is what does Dispatcher Servlet do.
Is it something like getting the information thrown from the web page and throwing it to the controller.
Is there any way to covert from toString back to the object in Java?
For example:
Map<String, String> myMap = new HashMap<String, String>();
myMap.put("value1", "test1");
myMap.put("value2", "test2");
String str = myMap.toString();
Is there any way to convert this String back to the Map?
Is there a way to print numbers from 1 to 100 without using any loops or conditions like "if"?
We can easily do using recursion but that again has an if condition. Is there a way to do without using "if" as well? Also no repetitive print statements,or a single print statement containing all the numbers from 1 to 100.
A solution in Java is preferable.
Guys i have included jstl and standard.jar in lib directory under classpath. It says absolute uri http://java.sun.com/jstl is not found either in web.xml or in application. please let me know how to configure in websphere 5.1.2
In the below example,
class ex8
{
public void show()
{
try
{ int a=10/0; return;}
catch(ArithmeticException e)
{ System.out.println(e); return ;}
finally
{ System.out.println("Finally"); }
}
public static void main(String[] args)
{
new ex8().show();
}
}
the output is:
java.lang.ArithmeticException: / by zero
Finally
How is it that Finally gets printed in spite of return statement in catch?
Hi,
Is there an elegant way in Java to code:
if (10 < x < 20) {
...
}
i.e. "if x is between 10 and 20"
rather than having to write
if ((x > 10) && (x < 20)) {
...
}
Thanks!
I'm creating an email using String Template but when I print out a date, it prints out the full date (eg. Wed Apr 28 10:51:37 BST 2010). I'd like to print it out in the format dd/mm/yyyy but don't know how to format this in the .st file.
I can't modify the date individually (using java's simpleDateFormatter) because I iterate over a collection of objects with dates.
Is there a way to format the date in the .st email template?
Hi folks,
I have a little program allowing users to type-in some regular expressions. afterwards i like to check if this input is a valid regex or not.
I'm wondering if there is a build-in method in Java, but could not find such jet.
Can you give me some advice?
Best regards
Phil
In Java, which is faster:
Cloning an Object, then passing it to multiple listeners assuming the cloned object contains nothing more complicated than nested arrays, primitives and Strings
Using Streams to pass data through from one object to another?
here's an example of a company selling complete software suite/platform
www.ql2.com/technology/platform.php
i wonder how are such suite/platforms developped ? do you have to use J2EE ?
i am more interested in how this company is able to produce their own proprietary WebQL language.
www.automationanywhere.com/products/AAServer.htm
is another similar company selling "servers"....how are such proprietary servers developped with Java technology ?

Hi,
I'm new to Java Annotation. I know how to create custom annotation but I don't know how to process that Annotation to generate the dynamic code just like ejb 3.0 and hibernate does.
I read some articles based on APT but no one gives the details about how to process the Annotation.
Are there any tutorials with sample code for processing custom Annotations?
Thanks
I saw this video, and I am really curious how it was performed. Does anyone have any ideas? My intuition is that he scraped pixels from the screen (one per 'box'), and then fed that into some program to determine the next move.
Is scraping pixel-by-pixel the way to do this, or is there a better way? I am looking to do something similar with either Java or Python.
Thanks
Hi,
Is it possible to generate word documents (*.doc) in java web application using Eclipse BIRT (Report Engine)? I want .rptdesign to be an input file in generating process. I could not find any example or tutorial.
What would you recommend as an alternative solution. As far as I know Jasper Reports allow only RTF format generation.
Thank you for your answer/explaination
Hi,
I need huffman code(best in python or in java), which could encode text not by one character (a = 10, b = 11), but by two (ab = 11, ag = 10). Is it possible and if yes, where could i find it, maybe it's somewhere in the internet and i just can'd find it?
I have data structured in Binary tree format, i want to represent it into an image(*. jpeg) then i need to display that image on web page and all the data will come @ runtime, so image processing should be done @ runtime, how to do this ?
This is what my thought solution any other suitable solution are also welcomed,
web site is in .NET , i am thinking to produce image using java api then integrate it to .NET wither through WEB-SERVICE call or any other solutions are also welcomed.
Hello,
My company wants to use Liferay for developing a portal and integrate Alfresco with it for document management.
But both Liferay and Alfresco are Java based and i would like to know if there are any alternatives to Liferay and Alfresco in PHP or Python.
Thank You
Hello,
I made a Java application which I would like to distribute on Windows, OSX and Linux without distributing a jar file. I used the great Windows exe wrapper http://launch4j.sourceforge.net/ to create an .exe file complete with my icon that won't scare Windows users.
Are there similar wrappers that I can use for OSX/Unix? An important consideration is that I would like to have my own icon on the executable (especially for mac users).
Thanks!
