  - by PCBEEF

  I got some sample code from the net here: http://www.javadb.com/sending-a-post-request-with-parameters-from-a-java-class That works fine. It sets the relevant headers in the response. However, what if I wanted to visit another url on the same site with those headers? If I create another URL object the session is lost. How do I maintain the session?

• Java Integer: what is faster comparison or subtraction?

  - by Vladimir

  I've found that java.lang.Integer implementation of compareTo method looks as follows: public int compareTo(Integer anotherInteger) { int thisVal = this.value; int anotherVal = anotherInteger.value; return (thisVal<anotherVal ? -1 : (thisVal==anotherVal ? 0 : 1)); } The question is why use comparison instead of subtraction: return thisVal - anotherVal;

• PHP Equivalent of Java Type-Casting Solution

  - by stjowa

  Since PHP has no custom-class type-casting, how would I go about doing the PHP equivalent of this Java code: CustomBaseObject cusBaseObject = cusBaseObjectDao.readCustomBaseObjectById(id); ((CustomChildObject) cusBaseObject).setChildAttribute1(value1); ((CustomChildObject) cusBaseObject).setChildAttribute2(value2); In my case, it would very nice if I could do this. However, trying this without type-casting support, it gives me an error that the methods do not exist for the object. Thanks, Steve

• How are integers casted to bytes in Java?

  - by helixed

  I know Java doesn't allow unsigned types, so I was wondering how it casts an integer to a byte. Say I have an integer a with a value of 255 and I cast the integer to a byte. Is the value represented in the byte 11111111? In other words, is the value treated more as a signed 8 bit integer, or does it just directly copy the last 8 bits of the integer? Thanks, helixed

• html truncator in java

  - by sammichy

  Is there any utility (or sample source code) that truncates HTML (for preview) in Java? I want to do the truncation on the server and not on the client. I'm using HTMLUnit to parse HTML. UPDATE: I want to be able to preview the HTML, so the truncator would maintain the structure while stripping out the elements after the desired output length.

• HttpOnly cookies on google app engine java

  - by Spines

  Anyone know how I can use httponly cookies for sessions and cookies on the app engine? In the javadoc for the Cookie class, http://java.sun.com/javaee/6/docs/api/javax/servlet/http/Cookie.html#setHttpOnly(boolean) , there is a setHttpOnly method. I get a compiler error when trying to use it when developing for app engine though. The method was introduced in the Servlet 3.0 spec, so its pretty new.

• Matching sentences with regex in Java

  - by Gary

  Hi, I'm using the Scanner class in java to go through a a text file and extract each sentence. I'm using the setDelimiter method on my Scanner to the regex: Pattern.compile("[\\w]*[\\.|?|!][\\s]") This currently seems to work, but it leaves the whitespace at the end of the sentence. Is there an easy way to match the whitespace at the end but not include it in the result? I realize this is probably an easy question but I've never used regex before so go easy :)

  For a rich text editor that has to handle pasted HTML code from MS Office applications, I'm looking for a Java library that cleans up the content of all "style" attributes in HTML elements, so that only some CSS attributes are left: background-color border color font-family font-weight font-style list-style-type text-align text-decoration vertical-align For creating a well-formed HTML document, I can use JTidy. For HTML element transformations (removing unwanted elements), I can use http://htmlparser.sourceforge.net/ Is there anything comparable for CSS attributes?

• The speed of Ruby and Java.

  - by Simon

  In every benchmark that I found on the web it seems that Ruby is slow, much slower than Java. The Ruby folks just state that it doesn't matter. Could you give me any example that the speed of Ruby on Rails (and the Ruby itself) really doesn't matter?
