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 convert method, which takes a String and a class as arguments and constructs an object of the given class, which will be returned.
The usage should look like this
Something s = Converter.convert("...", Something.class)
Is it possible to express this with Java generics?
Something like:
public static <T> T convert(String source, ??? TClass)
What would be ????
I've tried before some Eclipse plugin (I don't remember its name) but it was lacking a lot of features (generics, for example). Is there anything easy to set up that would run on the last version of Java?
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!
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.
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the legacy API's in the Java's Collection Framework and I learnt that classes such as Vector and HashTable have been superseded by ArrayList and HashMap.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they are NOT deprecated, and deemed as legacy when essentially, deprecation is applied to software features that are superseded and should be avoided, so, I am not sure when is a API deemed legacy and when it is deprecated.
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 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)?
I need to access the Serial Ports with Java in Windows Vista and FreebSD

I want to do AES CBC encryption in Java. I'm using javax.crypto. After I have the Cipher initialized, do I only need to call doFinal on the clear bytes to properly encrypt it? Or do I need to do something with update?
Documentation says update:
Continues a multiple-part encryption
or decryption operation
and doFinal
Encrypts or decrypts data in a
single-part operation, or finishes a
multiple-part operation
what exactly do they mean by multiple-part encryption?
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?
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.

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 am very new to Hibernate. I have MySQL database and mapped pojos. What should I do next? I know little bit LINQ to SQL from .NET, and it generates me List of mapped objects.
So basically, what are my next steps after creating POJOS if I want to have List of them and do CRUD operations upon them and data will be also saved in DB not only in java objects ?
kthx
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)
I need to write a software, which launches DRM jobs in a customer environment and monitors those jobs status.
It should work with various customer environments and DRMs - like LSF, Sun Grid and others.
Can you recommend some 3rd party library, which hides DRM differences from me and has API like "launch job", "get list of jobs", "get job status" etc. ?
Both Java and native libraries are good for me.

Hello,
I'm currently having some issues with a Java application I'm developing. Namely the JVM is crashing with a segfault. I'm trying to locate the hs_err.log file which should contain some helpful info about the issue.
However, I can't find this file. I've used find, locate, etc, and nothing.
Any ideas on why the log file isn't being generated?
