    Default java.sql.SQLException: Access denied

    I am getting an error from my Spring web application. I am trying to post to my MariaDB database, but I'm getting the following exception.

    org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLSyntaxErrorException: Access denied for user 'ghscom_frank'@'localhost' to database 'ghscom_frank'
    Model object must not be null

    The trouble is that ghscom_root is not the user name I have in my applicationContext.xml. I'm not sure what more information to give, so let me put down a whole lot, and I'm sure if someone needs more they'll ask. Here is the relevant portion of applicationContext.xml.

    	<bean id="dataSource"
    		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    		<property name="driverClassName" value="com.mysql.cj.jdbc.Driver" />
    		<property name="url" value="jdbc:mysql://localhost/ghscom_ghs86" />
    		<property name="username" value="ghscom_frank" />
    		<property name="password" value="GHSMatadors1986" />
    	</bean>

    This is from my controller.
    	public String writeComment(@ModelAttribute("name") String name,
    			@ModelAttribute("comment") String commentString, Model model) {
    		Calendar date = Calendar.getInstance();
    		Comment comment = new Comment();
    		comment.setName(name.trim());
    		comment.setComment(prepareCommentForDatabase(commentString));
    		comment.setCommentDate(((date.get(Calendar.MONTH) + 1) + "/"
    				+ date.get(Calendar.DATE) + "/" + date.get(Calendar.YEAR)));
     
    		try {
    			commentDAO.writeComment(comment);
    			List<Comment> comments = commentDAO.getComments();
    			model.addAttribute(comments);
    		} catch (Exception e) {
    			System.out.println(e.getMessage());
    			return "Oops";
    		}
     
    		return "GuestBook";
    	}

    This is from my DAO class.
    	public boolean writeComment(Comment comment) {
    		boolean successfulWrite;
    		Calendar date = Calendar.getInstance();
    		comment.setName(comment.getName().trim());
    		comment.setComment(comment.getComment().trim());
    		comment.setCommentDate(((date.get(Calendar.MONTH) + 1) + "/"
    				+ date.get(Calendar.DATE) + "/" + date.get(Calendar.YEAR)));
     
    		try {
    			this.getJdbcTemplate().update(
    					"insert into comments(comment_date, name, comment) values ('"
    							+ comment.getCommentDate() + "', '" + comment.getName()
    							+ "', '" + comment.getComment() + "')");
     
    			successfulWrite = true;
    		} catch (Exception e) {
    			System.out.println(e.toString());
    			successfulWrite = false;
    		}
     
    		return successfulWrite;
    	}

    I have also tried granting privilege to the correct user, but I get the following:
    MariaDB [(none)]> grant all on ghscom_ghs86 to ghscom_frank;
    ERROR 1046 (3D000): No database selected

    Default Re: java.sql.SQLException: Access denied

    This issue is fixed. I made some fixes to applicationContext.xml and servlet.xml files. I'm not sure what I did, but this works now.

    Default Re: java.sql.SQLException: Access denied

    Solution is to remove data folder from following location.

    Cocuments and SettingsAll/ UsersApplication /DataMySQL

    This directory contains temp files and old DB data including your last login credentials used in previous installation. So, to solve this issue:

    Uninstall MYSQL server
    Remove everything from above folder
    Install a fresh MySQL server[COLOR="Silver"]
