Hi I want to upload file in postgres database using java servlet but I am not understanding how to set prepared statement for file as we should use bytea for postgres not blob. Can you help to resolve this issue. I tried using getBytes(), BinaryStream but I am getting errors as
java.lang.AbstractMethodError: Method org/postgresql/jdbc3g/Jdbc3gPreparedStatement.setBinaryStream(ILjava/io/InputStream;)V is abstract
Below is my html code
<form method="post" action="Upload" enctype='multipart/form-data'> id="onelevel" name="onelevel"> id="twolevel" name="twolevel"> id="threelevel" name="threelevel"> id="fourlevel" name="fourlevel"> id="fivelevel" name="fivelevel"> class="docu" name="docu"> type="file" name="data" accept=".doc,.docx,.xml,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document" > <button>Uploadbutton> form>
