Error 500 launching the Web Service Explorer with Eclipse - java

I created my first web service and all seems to run ok, but when I launch the Web Service Explorer, it returns a HTTP ERROR: 500.
I'm using the version Luna Service Release 1 (4.4.1) of Eclipse, Tomcat 8.0.14, Axis2 1.6.2 and JRE 1.8.0_25. I read that it's solved changing the version to jre7, but i didn't work.
[Edited]
What I was doing is this tutorial. The problem comes when I tried the second part. Instead of appears the Web Services Explorer I get the 500 Error.
Thanks for your help! :D

Try changing JAVA_HOME and path to 1.7 JDK instead of 1.8. The problem is due to java 8 which doesn't seem to be compatible with luna as of now.

I had this same issue with Eclipse kepler when launching the Web Services Explorer-- I had jdk1.8 installed. Tried changing the JAVA_HOME (path points to %JAVA_HOME%) to point to jdk1.7 and still got the same issue.
After some research I decided to go with uninstalling jdk1.8 and this worked (somehow).
Totally a work around and not a solution; This got the Web Services Explorer to work for me.

I'm having trouble installing TestNG on eclipse Photon Release (4.8.0), OS-win10, java version 10.0.2

I'm having trouble installing TestNG on eclipse Photon Release (4.8.0), OS-win10, java version 10.0.2
I get the below error. Also when I tried to access testng.org it says "Service Temporarily Unavailable". Please help. Thank you.
"HTTP Server 'Service Unavailable': http://beust.com/eclipse/content.xml
HttpComponents connection error response code 503."
Scrrenshot of the error
TestNG project is very much alive.
There was an outage on the site, which was raised with the service provider and fixed thereafter. The site is back online.
Please try again.
It was just a temporary ISP outage, http://testng.org is back up.
The project is alive and well, and we're busing working on the next major version.
I had also faced same issue in latest version of Eclipse(as of today) and following is the workaround that worked for me
In Install new Software dialog of Eclipse enter URL http://beust.com/eclipse instead of https://beust.com/eclipse
Happy testing :-)

Eclipse Neon (MAC OS), Static Web Project doesn't work (could not find JRE executable)

I am new to programming and webdesign. I started with Eclipse some months ago to learn Java. Everything works fine. When I tried today to run a Static Web Project on a HTTP Server Preview (like in that Tutorial https://www.youtube.com/watch?v=URCyWNflkpQ), Eclipse had some issue with an older Java version.
I found Java JDK (1.6) that I deleted afterwards.
I reinstalled the latest Java JDK (1.8.0_60) and made sure that only this version is in the /library/java/... . I got me a new Eclipse version as well (Eclipse Neon). Running Javaprojects like before still works.
As soon as I try to run my HTMLfile, Eclipse shows me the errormessage:
'Starting HTTP Preview at localhost' has encountered a problem.
Could not find JRE executable
When I try it with J2EE Server Preview it works though. Can I simply use this Server Preview instead? This errormessage took me hours of hopelessly searching the internet for answers. Maybe for nothing...^^
Here somebody had the same issue, but on windows. I tried the solutions, but they didn't work either:

Thanks for the help!
It's a Mac-specific bug. It'll be fixed in Oxygen.1.

Spring Source Suite (STS) 3.0.0 Rel automatically closes once the IDE is loaded

Needed help in resolving the issue related to STS 3.0.0 IDE.
When I open the IDE it
prompts for the workspace location
After giving the location it loads the necessary plug-ins
Opens the IDE with the default perspective
After that it immediately closes off.
Environment:
OS: Ubuntu 14.04 64bit
Java: 1.7
Note: Latest versions are there, because of the project dependencies I am using the STS 3.0.0 Release.
I have tried with STS 3.6 RC1, it is working properly
Cheers,
Raj
I was facing the same issue and I just uninstalled JDK and then reinstalled it then this issue got resolved.
Try with different jdk like 6 .If its still not working try in another operation system or different version it.

Google plugin for Eclipse Luna not showing the icon

I have been around 4 hours trying to install the Google Plugin for Eclipse Luna. I followed every step of the installing guide but when i finished the Google Logo for starting a new project didnt appear as it should:
As you can see even though i have the plugins installed i cant see the icon or start a new web project.
My operating sysyem is OSx Yosemite. I tried updating to Java 8 and JDK 8 (and 7) and deleting all the files as this question recommends. Also deleted and "reinstalled" eclipse and the plugin a lot of times but didn't workout.
Anybody with the same problem? Thanks a lot.
I had the exact same problem on my new MacBook. I had to install JDK 7. I downloaded and installed the Mac OS X x64 version of 7u75 from here:
JDK 7 Downloads
After it installs make sure it's the system default by executing the following from the Terminal:
/usr/libexec/java_home
If it looks good to go then just restart eclipse and you should be good to go.
I suggest you even to delete your Eclipse_Luna:
Re-install your Eclipse and then install the GAE-plugin again.
Remember to re-start your Eclipse after you've successfully install the GAE-plugin for Eclipse_Luna.
I faced the same issue.
I installed JDK 1.7 and used 1.7 jre for eclipse as mapped and downloaded the eclpise plugin AND restarted and it worked fine.

Problem with GlassFish tools bundle for Eclipse and running Glassfish

I've downloaded the GlassFish-Tools-Bundle-For-Eclipse-1.2 and installed it.
When I run the eclipse contained in the release I'm unable to start the Glassfish server, which arrived pre-configured with the release.
It seems to be looking for the server under c:\ (i.e. c:\glassfishv3\glassfish) when in reality it's under {myDevPlaces}\bundle\glassfishv3\glassfish).
I had the glassfish-v3-prelude installed about a year ago but I uninstalled it.
I've bypassed the problem currently by moving the directory to c:\ but I'd appreciate an actual solution if someone has encountered this.
Thanks,
Ittai
FWIW, I'm using a standalone install of GlassFish 3 and the GlassFish Java EE Application Server Plugin for Eclipse (i.e. not a bundle) and everything is working fine.
Please note, As I have observed few days back, GLASSFISH AS 3.1 is compatible and to be downloaded for Eclipse Helios only.
