conflit version java :UnsupportedClassVersionError: Bad version number in .class file

I created a runnable jar with 1.5.0.07 java version, I deployed it to a server which runs with the same version of java,
I had two methods which use the same spring jdbc , when I run the jar in the server the first method works fine but the second return this error :

When I googled this problem, I find that's a problem of conflict different Java JDK but I don't get it because I have the same version of java in my project and in the server.

DJ Native Swing Browser in Java Swing For mac

I have a Java application made with Swing and I have used one DJ Native Swing Browser. When I tried to use that on OS X its throwing a NoClassDefFoundError all the time even though I have added swt.jar. Can some one please tell me what I am doing wrong ?

ya i too faced the same problem initially while executing on ubuntu.B'coz swt jar changes from OS to OS for Mac OS X mac download appropriate swt jar.Event Swt changes for 32 bit and 64 bit architecture so make sure you use proper swt jar
for msc go to below link
http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops4/R-4.3-201306052000/swt-4.3-cocoa-macosx.zip

After waiting long finally i found jar files for that.
here
http://download.eclipse.org/eclipse/downloads/drops4/S-4.4M5-201401231600/
in that
Mac OSX (Mac/Cocoa/x86_64)
that is for 64 bit mac systems. I run in mac With that swt.jar

Eclipse RCP application starts only as administrator

A few days ago we decided to start using Guava in our Eclipse RCP application. I downloaded guava-14.0.1.jar from http://central.maven.org/maven2/com/google/guava/guava/14.0.1/.
After I had started eclipse.exe the application crashed. The .metadata/.log file contained the following errors:

There is no error if the application is running as an administrator.
The application is 64 bit, so this is not an UAC virtualization issue. But it looks like the problem is somehow connected with permissions.
guava-14.0.1.jar seems to be a valid OSGi bundle: https://code.google.com/p/guava-libraries/issues/detail?id=688 (At least I found all necessary headers in MANIFEST.MF)
Any suggestions?

I fixed my problem by wiping out C:\Users\<user_name>\.eclipse folder. It looks like the problem was somehow connected with OSGi (Equinox) temporary directories.

Double check if you have included the bundle in the feature that you are using in the product configuration of your RCP.
Double check if you are using the right symbolic name and if you are requiring the right version.
I had a problem like yours because the guava jar was not being copied properly to the target platform at build time.
In my case I had to add the following in the feature.xml to ensure the version 0.14.1 was being copied since Eclipse Xtext and other components uses an older one:
<requires>
<import plugin="com.google.guava" version="0.14.1"/>
....
</requires>
<plugin
id="com.google.guava"
download-size="0"
install-size="0"
version="0.0.0"
unpack="false"/>

Based on your last comment, I'd think this isn't Java or OSGi related, but probably just a filesystem permission issue.
You may want to:
check that particular folder and its subfolders and files for unusal permission requirements (right-click, properties, security tab),
delete the entire folder, recreate it, and try again to check for a different outcome.

Exception: java.lang.RuntimeException: java.lang.NoClassDefFoundError: org/jdesktop/beansbinding/Property
I have read some places that I need to right click on my project and then go to the libraries. Once I'm there I do have Beans Binding Library installed. Also there was somewhere else where a beans.jar file is installed (which I have).
How do I solve this run-time exception?

Add the Jar containing the org.jdesktop.beansbinding.Property class to the archive attribute of the applet element.

Where can I put my Jar file so that eclipse RCP can see it?
Oracle version- 10g express

Where can I put my Jar file so that eclipse RCP can see it?
In an RCP project you can not include JAR Files directly. One way to include is create separate plug-in project from JAR file and include that new created plug-in as Dependency.
