Does anyone knows of a library or a class that emulates the vt100 terminal (doesn't matter if graphical or not). What I want basically is a class that implements the logic of a vt100 terminal (like when receiving a "delete" code will call a delete function, or if GUI based that will delete one char).
Telnetd seems to be a complete and pretty well documented solution:
http://telnetd.sourceforge.net/
You can also try:
http://www.jcraft.com/jcterm/
It behaves like a VT100 and uses a SSH2 connection. But the website indicates the VT100 emulation is incomplete.
Have a look at the JediTerm project: https://github.com/JetBrains/jediterm
It has both graphical implementation as well as API to override.
Graphical version works for remote SSH connections(using JSch) and local pty(using Pty4J).
It is a mature project used for the embedded terminal in JetBrains products.

I am searching for an up-to-date java2html tool, which supports Java 8. In the past I used java2html.com which created created really useful HTML code. However, I am in trouble now, because this tool not even supports Java 7 language constructs, not mentioning Java 8. If you know any similar standalone tool, which not only transfers the Java code to HTML, but also generates a browser and even it is a piece of cake to integrate it with Ant/Maven/Gradle, please let me know.
One solution is to use javadoc's -linksource option, however, it does not colour the code. A workaround might be a javascript solution running on node.js and colouring the code with highlight.js. I chose this solution and automated the highlight.js integration with gradle.

I am new to Java programming language. And would like to do a small app to learn on and get a head start into java.
I use an app called unlocker from emptyloop dot com. But its got adware, etc. So I just wanted to learn how to write my own app for myself to delete undeletable file or folder in windows.
Can anyone help me out, or know where I can find an example, I tried googling, but had no luck.
Well, I guess Java wouldn't be the right choice for that since it's a platform independent framework. And 'unlocking' files is very platform dependent in my opinion
But maybe you take a look at ForceDel. It's open source software and claims to do what you are looking for.
ForceDel uses some exciting new APIs introduced with Microsoft Windows Vista to determine which processes have a specified file in use. With this information, ForceDel is able to close the file in the remote process address space and then delete the file.
Starting with version 1.2, ForceDel can also delete files on Windows XP.

I'm trying to create an app for Android that simply sends a command to an SSH server. No response needed, I just need to be able to send a command. I was wondering if there's any java library out there that I could use?
No advanced stuff needed, just a pure connection to send the command.
You are searching for JSch.
Other libs are jaramiko, paramiko, trilead-ssh2 . A place where you can browse the source for trilead is the connectbot project. Please notice that connectbot also uses this unmaintained lib.
It also exists a commercial SSH Java lib: J2SSH Maverick

I am trying to create an application which entails communication with an OPC HDA server to get historical values of tags.
I was wondering if there are any free/open source libraries available in Java which can help me do that.
I have already tried the following options:
Integration Objects Java Wrapper: It internally uses JNI. When client and server are not co-located, it is difficult to get it working. It is licensed.
jInterop: Implements the MSRPC protocol and thus does not rely on JNI. Is portable. However, the OPC HDA interfaces are quite complex and I was not able to call them via jInterop. Also the errors that it throws are quite obscure, so troubleshooting is a major issue with this library. The call that I was not able to get working was the IOPCHDA_SyncRead::ReadRaw.
For the reasons stated above, I am not keen on using both these libraries.
Any help/pointers will be greatly appreciated.
Thanks,
Saurabh

I am looking for a translator for translate Java ByteCode to Machine Native Code before execution to improve performance.
I heard that OpenOffice is made with JAVA, but I can't see any jar file in his installation folder, therefore, maybe there is a translator but I can't find it.
Does anyone know some tool or comercial product to do that?
Thanks!
There are multiple solutions. All are not ideal.
Take a look here (exe4j). To learn more read this article.
Give a look to Avian JVM. See my reply here to this question for pointers on how to embed it and what class libraries you can use to generate your stand-alone executable.
if you just need a managed language/platform, you can also use .NET/Mono AOT. See the mkbundle tool included with Mono 2.x.
Please have a look into https://www.graalvm.org/.
It could build a native image from your jar and run it as binary (native code).
