Hi Community I try to upload file , but in my action class I am getting null pointer exception.

Below is part of my code

@Override
public void doAction(HstRequest request, HstResponse response) throws HstComponentException {

    System.out.println("In Action");
    try {

        Part part = request.getPart("file");
        InputStream fis = part.getInputStream(); // getting null pointer exception as part is null
        int content;
        while ((content = fis.read()) != -1) {
            // convert to char and display it
            System.out.print((char) content + "-" + content);
        }

}

Did you submit the form with POST method and enctype="multiplart/form-data" [1] and <@hst.actionURL/>?

you cannot use Parts API, without configuring tomcat first,
you need to change context.xml and add allowCasualMultipartParsing="true" parameter (https://tomcat.apache.org/tomcat-8.0-doc/config/context.html ) and you also might need to change connector so it accepts more than 2MB default upload size ( maxPostSize)

Much easier is just to use file upload lib:


    <dependency>
      <groupId>commons-fileupload</groupId>
      <artifactId>commons-fileupload</artifactId>
      <version>1.3.3</version>
    </dependency>

API is almost the same..
cheers

        InputStream fis = part.getInputStream(); // getting null pointer exception as part is null
        int content;
        while ((content = fis.read()) != -1) {
            // convert to char and display it
            System.out.print((char) content + "-" + content);
        }
