I have setup DCEVM + Hotswap Agent on my local machine with tomcat and eclipse. I followed steps given at
http://hotswapagent.org/mydoc_quickstart.html
i am using jdk1.8.0_112 so i have downloaded DCEVM-light-8u112-installer.jar and patched my JVM using it.
when i start tomcat server in eclipse its giving below error
HOTSWAP AGENT: 19:38:57.939 ERROR (org.hotswap.agent.watch.nio.EventDispatcher) - No match for watch event 'sun.nio.fs.AbstractWatchKey$Event#3f5ed469', path 'D:\apache-tomcat-7.0.50\logs\log_file.log'
Use version 1.3.0 (https://github.com/HotswapProjects/HotswapAgent/releases/tag/RELEASE-1.3.0). This fixes the issue.

I loaded my Spring/Maven project in Eclipse (Spring Tools Suite variant), installed Run Jetty Run, and clicked Run Jetty.
PROBLEM: Jetty does not start correctly:

QUESTION: How can I fix it?
You are running an unstable version of Jetty.
Version 9.0.0.M3 is not a stable release (that's an experimental milestone release, a candidate for release, something to help integrators start to evolve their code for the eventual release).
Use a stable release, such as 9.3.12.v20160915 and you'll have a much better experience.
In 9.3.12.v20160915 the MultiMap class can be found in jetty-util-9.3.12.v20160915.jar
Also note, Jetty 9 is servlet 3.1, not 3.0.1 (seen in your output)
As explained by Joakim, 9.0.0.M3 is an old version of Jetty.
Fortunately, Run Jetty Run has been updated a few weeks ago.
Here is how to use the latest Run Jetty Run:
Uninstall from Eclipse any existing version of Run Jetty Run
Add this update site: http://xzer.github.io/run-jetty-run-updatesite/nightly/
Install from it the required component and the optional component 9.3.6
You now have Run Jetty Run using Jetty 9.3.6, which is a year old already but does not trigger the error above. Be sure to select it in Run configurations.
I am trying out a Fabric8 Spring Boot quickstart, following the steps documented here I get the following error:

I am running with Maven 3.3.9 and Java 1.8.0_91 on Ubuntu 14.04
Does this guide just not work, or am I missing something from my configuration?
Points to consider:
My ~/.m2/settings.xml is untouched
The project archetype that I download as part of the first step is untouched (aside from the mvn install
I am running Fabric8 inside JBoss Fuse 6.2.0.redhat-133 on my local machine
I have already tried running mvn -U fabric8:deploy -DskipTests to update snapshots (to no effect)
This totally useless issue is the only Redhat acknowledgement of this problem - and changing my Maven to the ancient 3.2.3 version (necessitating a change to Java 6 runtime) is not going to fix the problem going forward.
fabric8 v1 is part of JBoss Fuse, and you can find documentation how to use it as part of the JBoss Fuse product documentation: http://developers.redhat.com/products/fuse/overview/
The Maven Archetype goal to use is different version number than what you type, you must use the version number of the JBoss Fuse product version you use.
In the upstream community fabric8 is now on version 2 which is a different architecture based on Kubernetes and Docker. Unfortunately you found an old documentation of the fabric8 v1 in that gitbook. The fabric8 version 2 documentation is what you can find from the website at the documentation page: https://fabric8.io/
I have the following environment:
Windows 7 64-bit OS;
Eclipse Kepler SR2 32-bit + JDK 1.7 32-bit;
MobileFirst Platform Studio 6.3 20150106-1717
When I opened my eclipse I clicked on the green play button to start the development server, I got the following errors; or if I create a simple project and attempt to deploy it on the dev server, same errors come out; or if I delete the server and create a new one and then try to start it; or if I install 64-bit eclipse with 64-bit Java 7:

I tried everything but no luck, so please diagnose this issue, thanks.
This is unrelated to MobileFirst Platform, and may be instead related to the problem described in the following IBM tech note: http://www-01.ibm.com/support/docview.wss?uid=swg21584343
It is unclear from the question and comments if the workspace is in a different network drive than the Eclipse folder. If yes, consider placing both in the the same "physical location".
I did realize my system location was out of sync thus I did open the jvm.options file and copy pasted the below configuration
-Dibm.worklight.admin.db.type=DERBY
-Dfile.encoding=UTF-8
-Duser.language=en
-Duser.country=US
-Djava.awt.headless=true
-Dwas.debug.mode=true
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=10777
-Dcom.ibm.websphere.ras.inject.at.transform=true
-Dcom.ibm.ws.jmx.connector.client.rest.readTimeout=180000

-Xmx1024m
-Dos.name=Windows
-DwlSyncStart=false
-Dibm.worklight.rhino.debug=transport=socket,address=9000
Which worked in my case , all the best.
i try to set up super simple exteranl tooling in eclispe , that is javah

I'm running java 1.6 in Eclipse on my Intel Mac. I'm using the 1.6.0 version under System/Library/Frameworks and set the default compiler to this in Eclipse.
How do I attach the source code?
First, I downloaded the 1.6 source from oracle, thinking I could attach that 'cause the installed 1.6 didn't have source.
When I click a java class to get the Source Code Editor, there are problems:
first, the top line says Compiled from File.java (version 1.5 : 49.0, super bit)
most important, when I attach the 1.6 source jar file, it gets an error:
An error has occurred. See error log for more details.
Unable to create resource org.eclipse.ui.internal.misc.ExternalProgramImageDescriptor#50417ba8
This also appears in the error log:
java.lang.ClassNotFoundException: org.eclipse.ui.internal.views.log.LogView
at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:506)
The Eclipse version is: Eclipse Java EE IDE for Web Developers.
Version: Helios Service Release 2
Build id: 20110218-0911
When I click for installation details, I get:
An internal error occurred during: "Fetching children of _SELF_".
Registry Directory not available: /Users/rfrail/Downloads/eclipse 2/p2/org.eclipse.equinox.p2.engine/profileRegistry.
I'm running Eclipse from my Download directory (it's worked fine in the past); however, there are 2 folders for Eclipse:
eclipse, and
eclipse 2.
So that looks like a source of confusion right there. Eclipse operates fine otherwise.
Can you help, please?
http://java.decompiler.free.fr/ is your answer
it has an eclipse plugin which decompiles code in place
