Why are they different?

String fileUrl = "C:/TEMP/table.txt";
                        File file = new File(fileUrl);
                        ContentStreamUpdateRequest up = new 
ContentStreamUpdateRequest(
                                        "/update/extract");
                        up.addFile(file);
                        up.setParam("literal.id", file.getName());
                        System.out.println(file.getName());
                        up.setParam("uprefix", "attr_");
                        up.setParam("fmap.content", "attr_content");
                        up.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, 
true);
                        server.request(up);



The above code, if I start the server(tomcat) inside eclipse, it throws 
"SolrException : Internal Server Error"; but if I start the server outside 
eclipse, for instance, run "startup.bat" in tomcat's bin directory, it runs 
successfully.
I really don't understand Why they are different.


Thanks in advance!
