Exception shows that "Client client = Client.create(config);" code statement cannot executed.

private static boolean callFileDownloadDelete(User user, String fileUrl, boolean isDownloadCompleted) {
    ClientConfig config = new DefaultClientConfig();
    Client client = Client.create(config);
    client.addFilter(new HTTPBasicAuthFilter(user.getUserName(), user.getPassword()));

I am simulating the client-server interaction as if a real User performed an action, Do I have to create one instance of client per User, or Should at each performing of action Client be created?

Answer 1

I had a a similar error with the message:

WARNING: Cannot create temporary files. Multipart attachments will be limited to 4096 bytes. java.io.IOException: No such file or directory

It was because the folder ${APACHE_HOME}/temp didn't exists.

After creating the missing folder and restarting the tomcat, the error message stopped showing.

Answer 2

I have found out that ${APACHE_HOME}/temp folder has around 2 billion temp files, after deleting them all problem is resolved.
