If you hover over a standard library Java method in Eclipse, you get a hover over dialog. How can you change the color of the text in that hover over dialog ?
Thanks,

I want to print the content of a simple text file in java exactly the way the text appears in the text file. The print out has the same content as the text file but the format is not the same. tabs and line breaks are ignored in the print out. Any help will be very much appreciated.

Hi:
Is there a way in Java to do a Nslookup search on SRV records?
I need to bind to Active Directory and would like to use the SRV records to help determine which of the ADs in the cluster are live.
In command line the nslookup search string is: 'nslookup -type=srv _ ldap._tcp.ActiveDirectory domain name'
Thanks.

I need this in order to get the file and then parse it with an xml parser.
Anyone know any alternatives for this class?
I have been using XSL-FO and FOP Engine to generate PDF documents for required data. This works great, but lately I have seen some limitations in FOP especially when it comes to allowing user to enter text in a html editor which can be transformed to XSL-FO and given to FOP driver.
This brought me to point to ask this large community of well informed individuals about what are possible Open Source or even non open source libraries to generate PDF documents in Java?
Recently I ran into this error in my web application:
java.lang.OutOfMemoryError: PermGen space
It's a typical Hibernate/JPA + IceFaces/JSF application running on Tomcat 6 and JDK 1.6.
Apparently this can occur after redeploying an application a few times.
Does anyone know of a way, in Java, to convert an earth surface position from lat, lon to UTM (say in WGS84)? I'm currently looking at Geotools but unfortunately the solution is not obvious.

I've .NET framework 3.5 installed in my laptop. Just .NET alone, no Visual Studio. How can I run Java, Python, Ruby and Perl programs from the console? What are the commands used for running them?
Do I need to install something else also, for running these language files?
I am trying to load a dll in java using the following code
System.loadLibrary("mydll");
The project is placed in D:\development\project\ and i have placed the dll on D:. I then gave following VM argument in eclipse configuration
-Djava.library.path=D:/
But when i run i get UnsatisifiedLinkerError. After googling a bit, I used
System.load("D:\mydll.dll");
but again getting the same problem, could someone can help?
In java adjectives ending in -able are interfaces Serializable, Comparable etc... So why is Throwable a class? Wouldn't exception handling be easier if Throwable were an interface?
Obviously, changing it now is out the question. But could it be made abstract? Wouldn't that avoid the bad practice of throw new Throwable();
I am trying to use groovy to do shell scripting on unix, but I am not having any luck having one process retain the environment variables changed by another process. For example,
def p1 = ["bash", "-c", "source /some/setEnv.sh"].execute()
Now, I would like a second process, p2, to inherit the environment variables that was set in p1. How can I do this? I don't see anything in java.lang.Process or its groovy extension that would spit out the environment variables after the process has executed.
Hello.
Are there open source libraries for Java to make implementation of drag and drop easier?
I plan to make something like the one shown below:
The program is Alice, where you can drag some elements on the left and nest them to the right. It's open source, but they did not use any libraries I think. I'm wondering if we anyone know of open source frameworks that work this way, or assist in doing complex drag and drops.
I have to develop a specialised report editor in Java. The user will get a number of fields that can be layed out on a page plus some graphical elements. The resulting report design needs to be serialized into already defined database tables.
Is there any software library that will help to achieve this without reinventing the wheel? I have come across Eclipse GEF and Zest, but I am not sure if this really meets my problem.

Is there any way to have a code where it can be used to open PDF file in Java application but do not side to any platform. I mean using batch file in Windows could do that. Can it be any other way to have platform independent code to open PDF on fly.
I am porting some functionality from a C++ application to java. This involves reading non-modifiable data files that contain regular expressions.
A lot of the data files contain regular expressions that look similar to the following:
(?<=id="VIEWSTATE".*?value=").*?(?=")
These regular expressions produce the following error:
"Look-behind group does not have an obvious maximum length near index XX"
In C++ the engine being used supported these expressions. Is there another form of regexp that can produce the same result that can be generated using expressions like my example as input?
Hi,
Is there a way I can do a for loop for a certain amount of time easily? (without measuring the time ourselves using System.currentTimeMillis() ?)
I.e. I want to do something like this in Java:
int x = 0;
for( 2 minutes ) {
System.out.println(x++);
}
Thanks
Please help :/
In Java you can create an abstract class that contains only abstract methods. On the other hand, you can create an interface that declares the same methods. So can you use abstract classes instead of interfaces?
Cheers!
I recently moved from NetBeans to Eclipse and I very much miss one great feature - whenever I use method which throws some kind of exception, NetBeans alerted me and I needed to add try-catch and NetBeans automatically generated exception type for me. Is there something similiar for Eclipse?
f.e. : Integer.parseInt(new String("foo"));
NetBeans alerts I need to catch NumberFormatException.
Eclipse doesn't alert me at all
