and some other similar errors related to launching Studio referring to intellij and java as mentioned previously
On Version 2.3.2 : Usually While It is connected to the internet, the android studio's panel pops up and freezes , and while offline , the errors appear .
On Version 3.0.1 : in this version there is no pop up panel , the errors appear in this case.
the results alternatively change between mentioned forms!
I even upgraded my windows hoping that the problem would be solved.but it did not!moreover , I have tried several different versions of jdk, Studio and have defined JDK_HOME , JAVA_HOME . the result is annoying.
my system info:
processor : core i3 2120 # 3.3
installed memory : 4 GB
GPU: Nvidia GeForce 520 GT
Adapter Ram : 2GB

Http error 500 with GWT web application

I've read tons of materials but I can't figure out what's happening. I'm doing a simple web application with Eclipse Oxygen, GWT 2.8, MapDB3, when I try to launch the web app through Run as --> GWT development mode with Jetty I obtain the error above. I'm going mad.

I tried to add the kotlin's jar to my project's lib directory but the error slightly changes and it's alway http error 500 but about:

Finally I've figured out that MapDB 3.0.5 has a long list of dependencies.
I've installed all of them and that error disappeared but others are coming, but code related.

I already saw these errors but there was no answers.
Any ideas ?
Antoine

Ok, I answer to my own question, may be it could help...
It's still not working on linux, but it's now working on windows.
The only thing I did is ti strickly respect the folder name and structure
Let my explain:
When it was not working the structure of the folder was:
c:\wsoemm\bin...
now it's
c:\wso2\wsoeme-1.1.0\bin
This is the only thing I did to make it working
I would prefer running WSO2 EMM on linux so any help would be great.
Antoine

After 3 days it's now working on linux
you have to change the file null.ini wich is located at
/wherever you put the folder/wso2/wso2emm-1.1.0/repository/components/default
the default file is:
-install
/home/nira/git/EMM/product-emm/modules/p2-profile-gen/target/wso2carbon-core-4.2.0/repository/components/default
change it to:
-install
/wherever you put the folder/wso2/wso2emm-1.1.0/repository/components/default
That's it

Cannot open some applications in VisualVM

I am using Ubuntu 14.04 with Oracle JDK 8. I want to inspect performance of my application using VisualVM. I can inspect other applications like JDownloader but I can't inspect my own applications and Eclipse 4.3. Before I made fresh install of Ubuntu, I was using JDK 7 and I have no problem and using it without any configuration. It gives following log.

you should run visualvm on the same JDK version as your app, look at help->about->details (Java), mine was surprisingly jdk8 instead of jdk13 (I have both), so you can setup JDK version for visualvm manually etc/visualvm.conf, uncomment and setup parameter
visualvm_jdkhome=C:\Program Files\Java\jdk-13

run eclipse and your application with jvm parameters -Duser.language=en -Duser.country=us ...
then you will be able profile with jvisualvm.
for eclise put this two lines in eclipse.ini
-Duser.language=en
-Duser.country=us
maybe your pre installed Ubuntu had languge settings as english and you was ok.

Redhat is not listed as as supported configuration for JavaFX 2.2.
Nor is running JavaFX in a headless mode.
This may change for Java 8, but Java 8 has not been released yet, so the list of supported configurations for JavaFX running on Java 8 has not been published.
Currently the supported configuration set for Linux is only => Ubuntu 10.4+ gtk2 2.18+ with optional additional requirements for av codecs if you also want media playback support.
So try using a supported Ubuntu system instead of Redhat and you may or may not get that working in a headless environment.
I tested and it works fine with Redhat 6. Redhat 5 seems to be the problem.
Redhat Enterprise Linux 6 support will be added for Java 8 (to be released in the next few weeks).
A RHEL 5.5 support request was closed as won't fix, see RT-22564 "JavaFX Support for Red Hat Enterprise Linux 5.5".
If you can find a way to install gtk2 2.18+ on RHEL 5 you may be able to get it to work, though no promises.
