I have code that works fine with aws-java-sdk-1.0 .
I have downloaded the source for aws.java.sdk-1.6.4, have built, and included the jar within my project.
I am getting a null pointer exception.
java.lang.NullPointerException

Anybody have any idea what changed between 1.0 and 1.6 such as API changes?
After investigating the source code, it seems that it throws this exception because the property file com/amazonaws/sdk/versionInfo.properties doesn't have the property platform.

You need to make sure that jboss uses its own servlet-api.jar and not any other one. If you are packaging the servlet-api.jar in your war file then simply remove it and try.

The Java code for above exception is:

System.loadLibrary(library);
Can anyone help me solve above Exception?
I have a DSpace instllation on a Mandravia Linux. I didn't install it, in fact I know very little about it.
It was working fine until recently when submissions started taking too long and collections weren't being displayed. This last error is shown as:

I've been thinking that a good solution would be to make a fresh install of DSpace, but I'm afraid that the problem is corrupted data, null values or something of the sort.
What are your thoughts?
Checking the source, it appears that you have not set the recent.submissions.count property.
Relevant source code is here.
I have a problem with my project. I uploaded all my libraries to Tomcat Lib folder, and error occurred.

You shouldn't be putting stuff in the Tomcat /lib directory except, as noted by Mike Baranczak below, JDBC driver JARs. (And even that is true only for Tomcat 6.x and higher. It used to be that those would go in your WEB-INF/lib as well.)
Learn how to create a proper WAR and deploy it to the /webapps directory.

Spring's file-upload stuff uses Apache Commons FileUpload under the covers. You'll need to download that and include it in your app. This, in turn, also requires Apache Commons IO, so youi'll need that also.
you missed to add jar "common file upload" or "file io" or added older verson of jar
good example of file upload is http://hmkcode.com/spring-mvc-upload-file-ajax-jquery-formdata/
thank you
