cannot find symbol, java, classloader

Your Java file is missing an import statement for java.util.List, which is why it's failing to compile. Unlike String and Integer, List is not in the java.lang package. You need to import java.util.List, not java.lang.List. If I'm understanding your scenario correctly, your other program is generating the import statements and...

Convert MSB first to LSB first

c++,c,visual-c++

What was wrong is that you first assigned the value's MSB to the temp's LSB, then shifted it again to MSB and assigned value's LSB to LSB. Basically, you had interchanged *(m_pCurrent + 1) and *m_pCurrent so the whole thing had no effect. The simplified code: #include <iostream> using namespace...

Why can primitives not be stored in Java collections, but primitive arrays can?

Because Java arrays are objects, not primitives. And you can store references to objects in Java collections implemented as generic types. From the Java language specification, Chapter 10: Arrays: In the Java programming language, arrays are objects (§4.3.1), are dynamically created, and may be assigned to variables of type Object...

std::is_copy/move_constructible fails even though copy/move constructors are defaulted

Caffe: Extremely high loss while learning simple linear functions

After some analysis of the problem it turned out that I needed to configure Spring to allow option requests for my restlet in the web.xml file as shown below: <servlet> <servlet-name>ccrest</servlet-name> <servlet-class>com.noelios.restlet.ext.spring.RestletFrameworkServlet</servlet-class> <init-param> <param-name>dispatchOptionsRequest</param-name> <param-value>true</param-value> </init-param> <load-on-startup>2</load-on-startup>...

PHP Upload Script corrupting file, Size of file differs from source file

php

FTP_ASCII is intended to be used when handling text files, I believe you should use FTP_BINARY in order to properly handle your .zip file. Replace: ftp_get($ftp_conn, $local_file, $server_file, FTP_ASCII) with: ftp_get($ftp_conn, $local_file, $server_file, FTP_BINARY) And: ftp_put($ftp_conn, $server_file_u, $local_file_u, FTP_ASCII) With: ftp_put($ftp_conn, $server_file_u, $local_file_u, FTP_BINARY) ...
