Ok well I trying to follow the tutorial to create the Data Provider, but am having trouble compiling the DataProvider.java file that I have. I have created a com.lightstreamer.adapters.stockquotesystem in the Lightstreamer\adapters folder and have put my provider into this folder along with the adapters.xml file. When I compile the DataProvider I get the following errors, can someone help?
C:\Lightstreamer_Moderato\Lightstreamer\adapters\com\lightstreamer\adapters\stoc

Quick question do I need to create this in eclipse? Can someone help me out with this? Any help would be greatly appreciated.
Thanks.

To compile an Adapter, you need to include the Adapter interface in the Java compiler classpath. So, add ls-adapter-interface.jar file (located in “Lightstreamer/DOCS-SDKs/sdk_adapter_java/lib” within your installation) to your compiler classpath, be it command line or Eclipse.
