Question: This is my .html body content:

```
<form name="login"> 
    <table border="0" cellpadding="2.0" cellspacing="2.0" align="left"> 
        <tr>
            <td>Username&nbsp;</td>
            <td>
                <input name="username" type="text" id="username" maxlength="15"></input>
            </td> 
        </tr> 
        <tr>
            <td>Password&nbsp;</td>
            <td>
                <input name="password" type="password" id="password" maxlength="10"></input>       
            </td> 
        </tr> 
        <tr>
            <td>&nbsp;</td> 
            <td>&nbsp;</td> 
        </tr> 
        <tr>
            <td>&nbsp;</td>
            <td>
                <strong>
                    <input name="Login" type="button" value="Submit" onclick="Vlogin()"></input>
                </strong>
            </td> 
        </tr> 
    </table> 
</form>

```

...and javascript code:

```
function Vlogin()
{
    var user=document.login.username;
    var pass=document.login.password;
    if (user.value=="account1" && pass.value=="backup1") 
    { 
        window.location= "index.jsp";
    }
    else
        alert("Invalid username or password");
        user.focus();
    }
}

```

Answer: 
After importing the file, you can deselect the in library from properties section. It worked for me
If none of the above answers help, check the permissions of the folder which contains the projects. In Ubuntu from command line try this:

```
sudo chmod 777 Folder_Containing_Projects -R

```

The above command will give permissions recursively.
