JSON libs for Eclipse - java

I am trying to connect to a OpenShift PHP database that I already set up. I am trying to connect to it using a eclipse java class. I tried to use Google Http client files but I am not sure how to add these into my project. I tried adding in via a libs folder but it always shows a error. Can anyone guide me on this?

You need to add the library to your classpath in your project project properties.
Project > Properties > Java Build Path > Libraries
Put the jar in your libs folder and add a jar in the libraries settings. If you only get the source, then you have to add the source package to your source folder and everything should be fine. Alternatively you can link the source in externally. However, you should be getting the library as a jar so just throw that in the libs folder and add it in your project properties.

Android Eclipse NoClassDefFoundError for external .jar android files

I am facing Error:java.lang.NoClassDefFoundError when importing a jar and using its classes.
This problem might be thought of a duplicate to this question. But I have a different condition:
I have prepared a .jar file from Eclipse SDK for Android .so it has folder such as /res /assets etc.
I have goggled for solution tried some of the solutions:
Build path-> Configure BuildPath->Add External jar
Copy .jar to /libs directory.
None of them worked!!!
P.S. In a previous project i have already used SQLCipher.jar file by just by adding it to the build path and have faced no problems.Though It had some filename.dat (which i have to add into /assets folder) and i have no idea what so ever if that has any role in accessing methods in the class of the jar.
I strongly recommend using Android Studio, the gradle build system is much easier than adding the libs manually. Just add compile 'net.sqlcipher:sqlcipher-gradle:3.0.1' to the build script, and the library will be downloaded and added with 1 mouse click.
Eclipse is missing powerfull features that Android Studio has
On toppic:
You need to import the jars from the build config dialog, click import external jar and select your jar
The library you added may need some external library eg google play services or something, do check that

How to add jasypt plugin to eclipse

So I am using
Eclipse IDE for Java EE Developers
http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/keplerrc3
and I am trying to add the jasypt - 1.9.0 plugin to eclipse
Since I am not experienced in this, I only tried one way which is
1- Download the zip file form the following url
http://sourceforge.net/projects/jasypt/files/
2- Unzip the file into the eclipse subdirectory plugins
3- Restart eclipse
However it seems that there is something missing
Go to your downloaded file and go to the lib folder. In there, you have a whole host of jar files. It is most likely the jasypt-1.9.0 jar you want.
In Eclipse: go to: Properties > Java Build Path > Libraries
Choose to add an External Jar and navigate to the location of the jasypt-1.9.0.jar
This will add the jar and its libraries to your project. Note: Look at the API for what you are using if this doesn't work - you may require a different jar to be imported instead/as well.
This is the standard way to add any third-party libraries to your project.

Integration of external jar file in android application using adt 20

I am trying to use external jar file in android application. The jar file is running well in another java application but when I am trying to use the Jar file with Android Application by BuildPath-> Add External Jars; it is showing following errors
"could not find class referenced from method ".
Please help me out from this.
Thanks

Maybe the ADK update has messed-up with your project's build-path. Try removing the JAR and add it again to your libs folder, and do a Clean Project.
following poster's comment about not having a libs folder:
You should try this:
Remove all references to the JAR in your project -> your code should not build without error anymore
Create à libs folder at the root of your project
Copy the JAR into the libs folder
(If still not running OK) Right click your project > Android Tools > Fix Project Propertie
If you want to use a Jar in android application you may create it like this:
Open your IDE
Click on new
Choose new Android project
Give the name of your project
Check option make this project as library
