Jetty 6 : JSP support not configured

Got this when running jetty 6 in eclipse 3.3, make sure to include the jsp jars in the library definition for jetty, so your jsp source can be compiled. See this for more details.

confluence.public.thoughtworks.org - 502 error

CruiseControl Wiki 502 Proxy Error : it seems a bit odd that a company that brought us cruisecontrol for continual build intergration, can't seem to keeps its own web servers up and running for continual use.

Customised Eclipse Java Search Results View

I want to be able to have more control over the export options, on the resuts tree from eclipse java search. i plan to customise the search results view, to enable a table view where i can copy/paste various column details.

I've done my initial googling, but all the examples assume that there is customised search and search results extensions being added. I want my 'org.eclipse.search.searchResultViewPages' extension to recieve the same 'org.eclipse.jdt.internal.ui.search.JavaSearchResult' objects that the default view processes.

I want to reuse the default java search dialog



     icon="icons/full/obj16/jsearch_obj.png"
  label="%JavaSearchPage.label"
  sizeHint="460,160"
  extensions="java:90, jav:90"
  showScopeSection="true"
  canSearchEnclosingProjects="true"
  class="org.eclipse.jdt.internal.ui.search.JavaSearchPage">



but have a new customised class, that handles the layout of the search results.


 id="JavaSearchResultPage"
 point="org.eclipse.search.searchResultViewPages">
   id="org.eclipse.jdt.ui.JavaSearchResultPage"
  searchResultClass="org.eclipse.jdt.internal.ui.search.JavaSearchResult"
  class="org.eclipse.jdt.internal.ui.search.JavaSearchResultPage">



the starting point

http://help.eclipse.org/stable/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/extension-points/org_eclipse_search_searchResultViewPages.html

for writing your own java search queries

Ordinal 2684 LIBEAY32.dll - CruiseControl SVN

Setting up cruisecontrol today to work against a SVN repository. I got this odd dialog popping up when the modification set or update phases of the process are executed.



Which states "the ordinal 2684 could not be located in the dynamic link library LIBEAY32.dll". It seems the that SVN package has its own version of libeay32.dll, which might cause a conflict with the original windows version.


C:\WINDOWS\system32
C:\tools\svn-win32-1.5.2\bin


It seems that cruisecontrol SVN plugin is using the default JavaHL ( which calls one version of the DLL file via JNI).



I found this simular blog post on eclipse-subversive-ordinal-not-located-in-libeay32dll, where the workaround is to disabled the JavaHL settings.

I think need to find some way to get the modification set plugin to use the SVNKit api when it checks for updates.

I'm trying to create a tomcat runtime server configuration

Dom4j : DocumentHelper.createDocument()

Got this error from a xml file created using the Dom4j API.


javax.xml.transform.TransformerException: com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: The markup in the document preceding the root element must be well-formed.


We were missing the xml header in the file



because we didn't call the DocumentHelper.createDocument() method!

Hangman with Generics

I'm implementing a hangman game, which uses a HashMap to store a character and result of the character guess.


public abstract class Guess{}

public class CorrectGuess extends Guess{}

public class FailedGuess extends Guess{}

public class Hangman {
    private Map<Character,Guess> state = new HashMap<Character,Guess>();
}


I want to be able to get a list of the various correct and failed guesses, so the details can be displayed.

The nasty solution i've currently got is to use "instanceof", but i feel this misses the point of using generics.


// the calling code looks something like
void display()
{
    hangmanDisplay.display(getFailedGuesses());
    consoleDisplay.display(getCorrectGuesses());
}

public List<CorrectGuess> getCorrectGuesses()
 {
  List<CorrectGuess> list = new ArrayList<CorrectGuess>(secret.length());
  for(Iterator iterator = state.values().iterator();iterator.hasNext();)
  {
   Guess guess = (Guess) iterator.next();
   if(guess instanceof CorrectGuess)
    list.add((CorrectGuess)guess);
  }
  return list;
 }

public List<FailedGuess> getFailedGuesses()
{...}


I want to be able to use the generic parameter type to control what is added to the list.


// the calling code would then look something like
void display()
{
    hangmanDisplay.display(getGuesses(new ArrayList<FailedGuess>()));
    consoleDisplay.display(getGuesses(new ArrayList<CorrectGuess>());
}

/**
 * get all values of generic parameter type T in the HashSet and add to the list.
 */
public void getGuesses(List<? super Guess> list)
{
    state,values().iterator();
    // how can i compare the type thats in the iterator.next() with the type defined by T in the input parameter?
}

Java Generics

I think the The Craftsman 44: Java Generics 2 gives the best exaplaination on when to use extends or super when defining Generics.

Basically use

you can widen the type of a list by using ? extends X, only if you
plan on reading from that list

and

If you plan on writing to that list, use

The Open Closed Principle

The Open Closed Principle says that you should design modules that never change. When requirements change, you extend the behavior of such modules by adding new code, not by changing old code that already works.

NTLM with Firefox

Here are the steps to make sure Firefox supports NTML authentication:

  • Type "about:config" in the address bar,
  • In the Filter, type in "ntlm".  This should make the "network.automatic-ntlm-auth.trusted-uris" property appear,
  • Add ".you.required.url"

It should allow you to use Firefox to access the service.
