I am using the Jsoup.jar to get the keywords from the meta tag of several websites using MapReduce. The list of websites is being kept within a txt file. However when I compile the java file in terminal, it says that package org.jsoup.Jsoup does not exist. I made sure that the jar is in the same folder as that of the java file.
Screenshot of error:
You have to place the jar files in Distributed Cache it is a best practise to share the third party libraries,
Please have a look at below links for further help,

I am trying to download jsoup under the following link: https://jsoup.org/download but I am not sure where to save this in my library... Can someone help please!
Typically, things like that come in a JAR file, which is a fancy ZIP file for Java. All your JAR have to listed on the classpath. There are different conventions for where to put your JAR, but, for a simple app, they can be in the root directory of your classes.
I downloaded an Open Source tool from www.openempi.org used to find duplicate patients. It is referred to as an EMPI tool (Enterprise Master Patient Index). I am a .Net programmer and not a Java programmer, but I have worked with other Java products where I receive a Jar file and run it like a Windows executable.
The zip file contained several Jar files but when I double-click on them I get Failed to load Main-Class manifest from.... After I Googled this term and reading a few posts about it, including several on this site, this seems to indicate that I should have done something different when creating the Jar file, but I didn't create the Jar file. Will I need to use Eclipse or some other tool to get past this, or is there something I'm doing wrong when try to load the Jar? Could it be a Java version issue?
The zip also contained a ./conf folder with several XML, CSV, and SQL files.

I don't think you want to execute the .jars found in that .zip file. Instead, you should try using the Application.html found after extracting from the openempi-webapp-web-versionhere.war.
i wanna use weka source code (not jar file!)and i download weka-src.jar from this address
http://www.java2s.com/Code/Jar/w/Downloadwekadev379sourcesjar.htm
and i wanna have weka project in netbeanes in windows .i do step by step this site instruction
http://weka.wikispaces.com/Netbeans+6.0+%28weka-src.jar%29
when i extract jar file into src directory in my project,it give me a lot of error
such as:
package java_cup.runtime does not exist
and a lot of other error.
anyone can tell me how can i do that without any error ?? i am working on this problem for a week and i'm so tired.
please help me if you can.
you have to download java-cup.jar file And add this jar to your classpath
if you didn't find java-cup.jar then you can download jflex.jar jflex also contain java-cup classes so you can download jflex.jar from link below

I want to create one java application that will iterate an jar file and will give classes of that jar file.
I searched a lot but didn't get sufficient information.
I want java code that will open the jar file and will able to iterate that jar.
See:
java.util.jar.JarFile.entries()

I'm working on a java android project. this project requires to use specific commands.
these commands are all developed in c++/c but I've been given two files (.jar and .so) that are supposed to "turn them into" java, so I can use them in my java android project.
The thing is, what am I supposed to do with these 2 files?? I've read a lot of stuff (mostly about creating the .jar and .so, but I don't care about this step, for I already have the 2 files)
I tried to import the .jar (import external lib), I tried to add the .so via the static loading :
//static {
// System.loadLibrary("MySoFile");
// }
All I get is a stack overflow error or a problem with the DEX file...
Has anybody ever tried to do this??
I don't seem to get the point here...all I want to do is being able to use the commands in the .jar file.... ://
thanks in advance!!
Take a look at this answer about adding jar files. '.so' files can usually just be drag and dropped to the project.
All you need to do is make sure the jar is in your classpath and you can then access the classes within this jar. A jar is just an archive of classes, you don't need to load the library into memory or something similar.
