How do I make vim indent java annotations correctly?
- by wds
When indenting java code with annotations, vim insists on indenting like this: @Test public void ... I want the annotation to be in the same column as the method definition but I can't seem to find a way to tell vim to do that, except maybe using an indent expression but I'm not sure if I can use that together with regular cindent. edit: The filetype plugin was already turned on I just got a bit confused about indenting plugins. The accepted answer may be a bit hackish but works for me as well.Read the article

What is the best way to create a debugging web page for a computation in Java?

I'm developing a website that uses some complex computations (NLP-related). My customer wants to have "debugging" webpages for some of these computations where he can run them with arbitrary input and see all the intermediate results that occur during computation.

What is the best way to capture all these results on Java level to render them as webpage?Read the article

Best way to get the highest sum from a Matrix (using Java but algorithm is the issue here)
- by user294896
Sorry I dont know the correct terminology to use but I have a 3x3 matrix like this 1 3 4 5 4 5 2 2 5 and I want get the highest score by picking a value from each row/column but I cant pick the same row or column more than once , so the answer in this case is 3 + 5 + 5 = 13 (row0,col1 + row1,col0 + row2,col2) 4 + 5 + 5 = 14 is not allowed because would have picked two values from col2 I'm using Java, and typically the matrix would be 15 by 15 in size. Is there a name for what Im trying to do, and whats the algorithm thanks PaulRead the article

Is there a way to make eclipse report a general "catch (Exception e)" as an error/warning (in java)?

I'm trying to encourage a best practice of not catching general exceptions in Java code. eg: try { ... } catch (Exception e) { // bad! ... } Is there a way to flag this as an error/warning in Eclipse?

Do you know a tutorial how to create a CXF web service from existing Java code and embed it in Tomcat, and also generate a wsdl file so that any .NET system would be able to generate client code easily? I miss that WSDL creation point in, for example this http://www.ibm.com/developerworks/library/ws-pojo-springcxf/ tutorial. No wsdl file is generated. But still it should be present in my case to provide system interoperability.Read the article

Does anyone know of a good guide to configure GC in Java?
- by evilpenguin
I'm having trouble with a JVM running an app, whose heap memory looks like a comb. It's constantly jumping from 1.5 GB to 3 GB and slowly deteriorating to higher values. I'm using G1 GC algorithm, but have no idea how to configure it. I do not have access to the code of the app I'm running and, needless to say, it's a rather large app. So, bottom line, does anyone know of a good guide to configure GC in Java?Read the article
