My idea is to submit a document using a Java Client and not the browser. I could do this successfully using my *JAVA HTTP Client program* written by me. The server I used is Tomcat4.0.3 and a JSP program Upload.jsp (that uses com.orelly.servlet.MultiPart). If it works fine here it should work fine with any HTTP server including Zope. But when I try "Zope" server (with program http://localhost:8080/Examples/FileLibrary/addFile) it gives me a 500 error. I am posting the error message below if you can give some clue... (I used the specs from RFC1867) null: HTTP/1.1 500 Internal Server Error Server: Zope/(Zope 2.5.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) ZServer/1.1b1 Date: Thu, 10 Oct 2002 12:57:34 GMT Bobo-Exception-File: C:\Zope\bin\lib\cgi.py Content-Type: text/html Bobo-Exception-Type: ValueError Bobo-Exception-Value: bobo exception Etag: Content-Length: 1704 Bobo-Exception-Line: 603 getRequestMethod : POST getResponseCode : 500 getResponseMessage : Internal Server Error --------------------------------------------------------- Here is my entire working Java HTTP Client program --------------------------------------------------------- import java.io.*; import java.net.*; /** * RFC 1867 * ======== * Content-type: multipart/form-data, boundary=AaB03x * * --AaB03x * content-disposition: form-data; name="field1" * * Joe Blow * --AaB03x * content-disposition: form-data; name="pics"; filename="file1.txt" * Content-Type: text/plain * * ... contents of file1.txt ... * --AaB03x-- */ public class PostDocument { public static void main(String[] args) throws Exception { // // CONSTANTS // String url = "http://localhost:8080/Examples/FileLibrary/addFile"; // <--- Zope/Python // String url = "http://localhost:8080/rcn/jsp/UploadFile.jsp?action=upload"; // <--- Tomcat/JSP String docPath = "D:\\rcn\\java\\HttpURLConnection\\testdoc.txt"; String bndry = "AaB03x"; String paramName = "file"; String fileName = "testdoc.txt"; // // CREATE AN HTTP CONNECTION // HttpURLConnection httpcon = (HttpURLConnection) ((new URL(url).openConnection())); httpcon.setDoOutput(true); httpcon.setUseCaches(false); // ???
