I have a JNLP application which fails with the following error:
Cannot find JNIWrapper native library (jniwrap64.dll) in java.library.path: ....
I have Java 8 64bit installed and using IE11.
Any help on how to fix it will be appreciated.
Just to clarify: I did not write the application and only trying to run it.
You need 32bit java version to launch the JNLP application and not 64bit java
please run below command to check what version of java you are running
C:\RIM\SINGTEL\950_0\inproc>java -d64 -version
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

Once i integrate scala IDI in eclipse(by using eclipse marketplace) and restart it, i get the below error message.
Alert: Failed to create a java virtual machine.
java -version
java version "1.8.0_341"

I followed https://www.guru99.com/how-to-install-java-on-ubuntu.html to install Java on my 64-bit, x86, Ubuntu 18.04 system.
When I run "java -version", I get the output :
ariba#monster:~$ java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) Server VM (build 25.231-b11, mixed mode)
What does "Java HotSpot(TM) Server VM (build 25.231-b11, mixed mode)" mean? Is my JVM architecture 64-bit or 32-bit ? And what architecture of eclipse-installer should I use, then?
The Java HotSpot Virtual Machine is a core component of the Java SE platform. It implements the Java Virtual Machine Specification, and is delivered as a shared library in the Java Runtime Environment. So, HotSpot is an "ergonomic" JVM. Read more detail here, link.
JVM architecture which you post in the question is 32-bit. You can get 64-Bit info in the output if you JDK is 64-bit architecture.
λ java -version
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)
Just getting the latest 64-bit version eclipse. The architecture of eclipse-installer depends on your system architecture.

How do i fix this?
You are missing a space

Is Oracle Hotspot JVM is same as what we can download from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html ?
If not from where we can downlaod Java Hotspot JVM.
The link is HotSpot JVM
You can download it and check with
java-version
and will find like
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
I'm trying to install Netbeans 8 but the installer is not finding JDK.
But, I can't update my Java, I installed the update 51 of java 7 but when I go in terminal I get it:
Alessandros-MacBook:~ alessandrogarcez$ java -version
java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)
In "System preferences", I have version 7 installed.
It seems to have both version of java installed in my mac.
Someone can help me to solve it?
Thanks
I was trying to install jre-7u45-macosx-x64.dmg and I don't know why it doesn't overwrite java 6.
I've read a lot of topics, tried all of them.

After all of it, I just downloaded jdk-7u51-macosx-x64.dmg and it worked. The version 7 overwrited the 6.
