I'm searching for a tool, which compiles a JSP file into a Java file without using a servletcontainer like Tomcat or something else. Can anyone help me out?
I decided to store uploaded to servlet pictures in DB. But how to show them in browser (in particular div with css image-background style) without page reload?
In details: I have an full-AJAX web client that works with java servlet.
Thanks.
Could someone recommend a good and inexpensive software synthesizer which generates really good piano sound (sample-based); support for other instruments is not required. OS: Windows or MacOS. Java interface would be a great asset.
Consider a private method which is called from JNI and not used otherwise, generating a compiler warning about an unused method:
private void someMethodCalledOnlyFromJNI() { // WARNING: method is never used
// ....
}
This is some legacy code in Java 1.4 - so no dice on @SuppressWarnings.
What hack would you use to suppress this compiler warning?
I have a normal web service. Many java and .net users are accessing it. Can I update it to wcf without anyone having to change their code? Any tutorials?
On a webpage, is it possible to split large files into chunks before the file is uploaded to the server? For example, split a 10MB file into 1MB chunks, and upload one chunk at a time while showing a progress bar?
It sounds like JavaScript doesn't have any file manipulation abilities, but what about Flash and Java applets?
This would need to work in IE6+, Firefox and Chrome. Update: forgot to mention that (a) we are using Grails and (b) this needs to run over https.
I have some Domain classes such as Student, User etc which are used on server and client (gwt) sides.
Can I exclude this domain classes to separate maven-module, so I can add this module as dependency to other maven-modules (i.e. add this module as dependency to maven-module which contains gwt related stuff, so this domain classes will be generated to JavaScript, and add this module as dependency to "normal" (not gwt) Java maven-modules, so this domain classes won’t be generated to JavaScript)?
Hi,
I've switched my webserver from tomcat to jetty and encounter a "java.sql.SQLException: Io exception: Connection reset" when back from idle time (eg. i go out for a while) :(
This issue doesn't appear when i use tomcat. Does it come from jetty or i've done something wrong ?
Thank you!
I already have a solid knowledge of Object-oriented PHP as well as HTML/Javascript/MySQL plus a basis in Java.
Now I would like to implement my projects in an efficient way, whether it is a web project in PHP or an Android application.
My problem is once my code gets bigger I start messing error handling, with form validation etc, and I guess its because of my poor basis in software architecture.
Thanks.
I have a jar that runs forever (infinite loop with socket listening thread) and need it to run in the background at all times. An example would be: "java -jar test.jar" How do I do this? Thanks in advance!
Hi,
I'm a new user to this interesting forum!
I want start developing an application for android and before starting i want learn about some android features...
The first android feature is how to correlate finger motion on the screen with java...
Are there any source code examples that show how to draw with your finger on an android screen?
Can you suggest a good place for me to download an example?
thanks
Is there a way to annotate an anonymous inner class in Java?
In this example could you add a class level annotation to Class2?
public void method1() {
add(new Class2() {
public void method3() {}
});
}
In Java/C++, for example, do you casually say that 'a' is the first character of "abc", or the zeroth?
Do people say both and it's always going to be ambiguous, or is there an actual convention?
Can anyone help me? I am currently using eclipse java ide, and would like a plug-in that will automatically look at my classes and draw up a class diagram in UML.
any suggestions?
I was studying the legacy API's in the Java's Collection Framework and I learnt that classes such as Vector and HashTable have been superseded by ArrayList and HashMap.
However still they are NOT deprecated, and deemed as legacy when essentially, deprecation is applied to software features that are superseded and should be avoided, so, I am not sure when is a API deemed legacy and when it is deprecated.
I've to create a dataset from some text files, writing them as vectors of features.
Something like this:
doc1: 1,0.45 6,0.001 94,0.1 ...
doc2: 3,0.5 98,0.2 ...
...
each position of the vector represent a word, and the score is given by something like TF-IDF.
Do you know some library/tool/whatever for this? (java is better)
First time I am bit disappointed in StackOverflow cause my http://stackoverflow.com/questions/2571727/c-concurrency-vs-java-concurrency-which-is-neatly-designed-which-is-better question was closed.
My intension was just trying to gather knowledge from programming guru's who worked in both the programming technologies. Rather closing this question, please help me by discussing what is good, bad, and ugly in multi-threading part in both the platforms.
It is also welcome, if someone would like to compare with .Net 4.0 with JDK 6 (or JDK 7)
Hi all,
In my Java servlet code, I want to be able to programatically write to the jetty access log. I am aware that jetty will automatically log every incoming HTTP request to the access log. However, my servlet needs to occasionally append it's own line to the access log. Has anyone here done something similar?
Thanks!
I need to write two versions of the same application, one in .NET and the other one in Java.
So I'd like to write a single test suite, and then use it against both codebases.
Which testing tool would you advise me to use?

Is there any reason behind using date(January 1st, 1970) as standard for time manipulation? I have seen this standard in Java as well as in Python. These two languages I am aware of. Is other popular languages also follows the same standard?
Please describe.
I'm having difficulties with some general OOP & Java approach. There are various ways to let classes/objects communicate with each other. To give a simple example:
I need object A to perform action X.
Object A needs P, Q and R to perform this action X.
Will then Object A retrieve P, Q and R by itself (within action X), or must these values be parameters for action X?
DI creates an extra layer of abstraction so that if your implementation class ever changes you can simply plug in a different class with the same interface.
But why not simply refactor when you want to use a different implementation class? Other languages like Python and Ruby work fine this way. Why not Java?
Somebody knows an example of this? an application made with JSF 2.0 and EJB 3? directory structure, etc, those kind of things, I’m trying to approach the best way to create a Java EE app using those technologies.
What is the easiest way to do a GAE/J datastore backup?
It looks like there is python bulkloader.py tool to do backup for Python apps, but what should I do to backup Java app? Is there any way to use python tool?
