I have installed JDK 8 (1.8) and i am using eclipse .The problem is that the tooltip does not work for JavaFX methods and classes(it works well for other methods and classes) .When i hover over a built-in method or class i get this message :
And also when i go to the documentation files by holding ctrl key and clicking on a method or class identifier it shows this :
so how should i fix this?
also there was a similar question asked here but the answers were not helpful to me so i asked this question.
You should use e(fx)clipse who fixes this for you automatically else you'll have to fix your "Installed JREs" (in your preference) and point the source location of jfxrt.jar to the sources inside your JDK

I'd like to find all references to certain methods within my workspace. I used to do this using Eclipse's ⌘+shift+G / ctrl+shift+G hotkeys for all my Java classes, but now nothing shows up when searching in Scala classes using the Eclipse Scala IDE.
I'm currently using Scala IDE for Eclipse v3.0.3.
Is this reference searching functionality already supported in the Scala IDE, and if so, what is the shortcut for it?
Thanks.
I had this problem too and I ended up installing the Eclipse Quick Search plugin from the Spring team that normally ships as part of STS. It has no Spring dependencies and is easy to install separately from the Eclipse Marketplace. Use ⌘+shift+L and start typing and you get incremental search results.
Find references is implemented as feature but it is far away from being as powerful as the Java implementation.
You can find the actual key combination if you do a right click in the editor area and navigate to the "References" entry.
However, if the find references feature doesn't find anything, then it is clearly a bug and it would be nice if you could report your use case in the ticket tracker.
Did you try using Scala-Search? It's available from the same update site as the Scala IDE itself, and it should find Scala references. See Features docs.
I need to create a plug-in for Eclipse CDT that sends a "snapshot" of the source code of the currently opened editor each time the code is "built".
I am already capable of doing it each time the user presses a custom button created by me, but it would be great if it could be done when the "standard" "build" action is performed.
Do i need no create a plug-in of the type "builder"?
I am using Eclipse 4.4.0...
Can someone help me?! (Sorry for some english mistakes... :( )
One solution would be to create your own custom "Builder". Instead of actually building the code, it would invoke the functionality you already have.
For information on how to use the eclipse build system, please have a look here: https://wiki.eclipse.org/Eclipse/FAQ/How_do_I_implement_an_Eclipse_builder%3F.
Also, this website goes into more details about building in eclipse: https://www.eclipse.org/articles/Article-Builders/builders.htm. However, I think that the first one should do.
As a side note, this works with any kind of eclipse project (JDT and CDT). The build described there is common to all flavours.
Hope it helps,

I could not find org.eclipse.search.internal.ui.searchpreferencepage.java in eclipse 3.7.2 version.It was available on eclipse 3.2.2. Can any one help me on finding that why this class has been removed from latest version and is there any alternative for this class on new version.
Is there any limit related methods on eclipse 3.7.2 plugins?
This is an internal class and consequently is not part of the Eclipse API and is subject to change without notice (see Eclipse API Rules of Engagement).
However it is still present in Eclipse 4.3 but is marked x-internal:=true in the Export-Package in the MANIFEST.MF. It is also present in Eclipse 3.8, in both cases in the org.eclipse.search plug-in.
The table limits which used to be in the preference page were removed some time ago, probably when the option to show the results in a tree was added.
Edit:
Further research shows the limit was moved from the preferences page to the Search Filters dialog in the drop down menu of the search view. The limit configured here can be accessed using the getElementLimit() method of org.eclipse.search.ui.text.AbstractTextSearchViewPage
getElementLimit() returns null if there is no limit.
There are quite a few questions with similar titles, but please read on as this is subtly different and I've not yet been able to find a solution in the many answers given to those other questions.
Scenario:
I have an external JAR file with a separate HTML tree javadoc. I have pointed Eclipse at the javadoc by completing the JAR's "Javadoc Location" in the build path dialogue. The source is not available to Eclipse.
At first it looks like this is working fine. If I hover over a class name (say, Wibble) the corresponding javadoc text pops up.
However, if I hover over a method (say the word create in blah = Wibble.create();), I get the pop-up "...the Javadoc could not be found..." which is confusing as it's just shown me the javadoc for the Wibble class.
Indeed, if I click on the icon within the pop-up to "Open Attached Javadoc in a Browser" it correctly opens the HTML and presents me with the text for the method that it just said it could not find!
Technical notes:
My Eclipse version is Android Developer Tools, Build: v22.2.1, though this was happening on vanilla Eclipse before I updated to the ADT version.
The javadoc is being generated by command line using the Doclava doclet.
Any suggestions about either what might be wrong in the javadoc, or in eclipse settings, or...?
EDIT In the course of subsequent experimentation I've found that this problem only occurs with a combination of Eclipse and javadoc generated by Doclava. My pragmatic solution has been to generate the javadoc twice - once for human readability by using Doclava, and once for Eclipse readability using vanilla Javadoc.
If anyone knows these systems in depth I'd still love to know why.
(In order to not leave this 'unanswered' now that I have a solution)

Eclipse offers a plugin, which displays the abstract tree view of Java projects. After installing the plugin, the view becomes available. http://www.eclipse.org/jdt/ui/astview/index.php
Is there such a functionality / plugin also available for the Netbeans IDE? I didn't find an answer in stackoverflow. The results in Google dealing with AST in Netbeans are somewhat old (2007-2009).
I know that there are standalone tools which display the AST and also other IDEs which are more useful, if such functionality is required (like IntelliJ Idea).
My question is Netbeans-specific - if this is not possible with Netbeans (without using other tools) a simple "No" will be enough! I am using Netbeans 7.3.
Did you look at these ? It is more recent (2012).

The dev builds of NB already contain such a view in the navigator. Not pretty but it works
