title: Need help in including all jar files in a directory to the existing project
body: <p>I have added a piece of sharepoint code to the existing java file which was compiling and working fine. The sharepoint code that is written uses some of the external libraries. Now I need to add the external library to the existing project through ANT.</p>
  
  <p>I have done a few modifications in the build.xml file and hence resolved all the compilation  errors. However when the code is getting executed, I get an Error message saying "java.lang.NoClassDefFoundError: net/entropysoft/eci/spi/IContentProviderFactory". Please help me resolving this error. </p>
  
  <p>Also please let me know what needs to be added in the build.xml file to resolve the error.
  All the jar files is present in the directory "externallibs"</p>
  
  <p>Thanks,
  Rajath</p>
