Jar file execution issue?

I am using this command to run my jar file
java -cp otpreq.jar com.otp.req.SendRequest
and its giving error-:
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/httpclient/methods/RequestEntity
at java.lang.Class.getDeclaredMethods0(Native Method)

Why this error is coming I can't figure out .
I checked the Library and org/apache/commons/httpclient/methods/RequestEntity is a Interface.

Assuming you have the http-client.jar:
java -cp otpreq.jar:http-client.jar com.otp.req.SendRequest
If O.S is windows, replace : by ;
Note: the newest httpclient is not located at apache commons, but at apache http components

You have to include all the supporting jars in class path (command line itself).
Or bind all your supporting jars inside otpreq.jar.
Either one of these will solve this issue.

Executing jar file throws class not found error

Using Eclipse, I am modifying a Java project we have been using for years. a specific class method is typically executed by sending a message through IBM WebSphere MQ. However, I now have a need to develop some new functionality and I need to be able to test it out side the MQ world.
I am able to successfully debug the application in Eclipse, but if I attempt to execute the jar file from a command prompt I receive the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: XMLBuilder/Node

My build is done using an ant script. This does not include a Class-Path attribute when creating the manifest.
The XMLBuilder.jar file is included in the target jar. Running jar -tf file.jar shows

... Omitted for Brevity ...
XMLBuilder.jar
What might I be missing?
Thank you

Run multiple jar files from batch file one by one

I've exported my Java projects into a runnable jar file with the libaries combined in another folder. I'm trying to the first one to run, when it finishes the second one starts, etcetera. Right now this is what my batch file looks like:
java -jar "C:\path-to-project1.jar" parameter /wait
java -jar "C:\path-to-project2.jar" parameter /wait
java -jar "C:\path-to-project3.jar" parameter /wait
java -jar "C:\path-to-project4.jar" parameter /wait
java -jar "C:\path-to-project5.jar" parameter /wait
However I'm getting the noclassdeffounderror. The only class I'm using in the projects is the main class, which is called "Main.java". It also says " a jni error has occurred. please check your installation and try again".
Should I also call the .lib files or am I missing something else?
This is what the cmd prompts:
C:\Users\EVE\Desktop>java -jar "C:\Users\EVE\Google Drive\Bots\LIVE BOTS\Builds\

I don't know whethere there are more bugs in the code but one is the location of /wait. Try start /wait java -jar "C:\path-to-project1.jar" parameter instead.

java .jar file convert to .exe file

I use launch4j to convert jar file to the exe file in Windows XP.
After I build wrapper, I go to test the wrapper.
However, it shows ""Error : A JNI error has occurred ,please check your installation and try again" and "A Java Exception has occured".
Below is the errors:

What does the errors say? How should I do?

You need to add a jar that contains the class
JXDatePicker
This is where you can get it from http://www.java2s.com/Code/Jar/s/Downloadswingx094jar.html
Add it in the libraries, and link the path..It must not give this error.
