Hi all,
I am struggling with a pb using RPC:
When I use the service to create and store my objects in my DB (Neo4J)
using remote service, all is Fine.
When I try to load my objects all is ok in my service class and in
Neo4J as well. But at the last line of the method public static void
writeResponse(ServletContext servletContext, HttpServletResponse
response, String responseContent, boolean gzipResponse) throws
IOException {
I have an exception.
Here is the method of com.google.gwt.user.server.rpc.RPCServletUtils
public static void writeResponse(ServletContext servletContext,
HttpServletResponse response, String responseContent, boolean
gzipResponse)
throws IOException {
byte[] responseBytes = responseContent.getBytes(CHARSET_UTF8);
if (gzipResponse) {
// Compress the reply and adjust headers.
//
ByteArrayOutputStream output = null;
GZIPOutputStream gzipOutputStream = null;
Throwable caught = null;
try {
output = new ByteArrayOutputStream(responseBytes.length);
gzipOutputStream = new GZIPOutputStream(output);
gzipOutputStream.write(responseBytes);
gzipOutputStream.finish();
gzipOutputStream.flush();
setGzipEncodingHeader(response);
responseBytes = output.toByteArray();
} catch (IOException e) {
caught = e;
} finally {
if (null != gzipOutputStream) {
gzipOutputStream.close();
}
if (null != output) {
output.close();
}
}
if (caught != null) {
servletContext.log("Unable to compress response", caught);
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
return;
}
}
// Send the reply.
//
response.setContentLength(responseBytes.length);
response.setContentType(CONTENT_TYPE_APPLICATION_JSON_UTF8);
response.setStatus(HttpServletResponse.SC_OK);
response.setHeader(CONTENT_DISPOSITION, ATTACHMENT);
*response.getOutputStream().write(responseBytes);*
}
And the return message on my console is:
