Foe now iam using mail.jar and iam able to send the static content easily.
But facing difficulty
1. maintaining the long HTMl code string .
2. How to substitute the values in the string with the dynamic values
Please can somebody help me with a proper solution. Or Best practice to follow in Email application !
Thanks in Advance !
You can put the email body in a properties file and read it from there.
For substitution, you can define "placeholder" in your String like {FIRSTNAME} {LASTNAME} etc., and then do a replaceAll for the dynamic portions in your code.
What u need to look into is "freemarker". Its a library and u can achieve your purpose with it.
You can use an WYSIWYG (What You See Is What You Get) Editor like CKEditor or TinyMCE, letting the user writing the html without even knowing html.
Then, after the user submitted the body, you take the output that is pure html,
and inject it into the mail body.
End of story...
Just remember to set mimetype to text/html and not to text/plain , or you will see the tags instead of their representation...

As per the html the source code is:
{result.data}
While requesting the URL result.data is set with 100 and am able to see the value as 100 in the browser. Where as while I am trying to execute the java program with the same url request I am unable to see the value as I have seen in browser.
URL url = new URL(site)
url.openConnection() etc..
I wanted to get the same content as I have seen in the browser through java program.
Your question is not very descriptive, but I guess you are trying to scrape data from the site.
You can use the following libraries for this task:
Jaunt (http://jaunt-api.com)
Jsoup (http://jsoup.org/cookbook/extracting-data/dom-navigation)
HTMLUnit
To what i understand, you want to do one of the below things :
Instead of reading the result line by line, you want to parse it as an XML to as to traverse to div(s) and other html tags.
For this purpose i would suggest you to use jsoup library.
When you hit the URL: www.abcd.com/number=500 in browser, it loads an empty div and on load it fetches data from somewhere, this data which it fetches on load, you want to fetch this using java ?
For this, there must be some js in the resulting page, which is fetching data by hitting some service on page load, you will need to look up in the page to know the service details and instead of hitting this URL (www.abcd.com/number=500) you will need to hit that service to get data.
I am trying to embed an image on a Freemarker ftl template to send as an email, I've based on this question Feemarker writing images to html, I did the exact same thing as this question said, but the email is being generated like this
What may be causing this error, and how to fix it?
My template looks like this
<img alt="My image" src="${imgAsBase64}" />
The image is a Chart, and I get the Base64 String, which I called imageBase64Str, via a Primefaces JavaScript function that generates the Base64 of the chart image, I pass it to the the bean and pass the parameter to the template like this
String encoded = imageBase64Str.split(",")[1];
byte[] decoded = Base64.decodeBase64(encoded);
String imgDataAsBase64 = new String(decoded);
String imgAsBase64 = "data:image/png;base64," + imgDataAsBase64;
emailParams.put("imgAsBase64", imgAsBase64);
String encoded = imageBase64Str.split(",")[1]; is suspicious. Looks like you are changing the base 64 string generated in some different way. Is the image actually a png or it's in another format? I think that if you remove that split and just do emailParams.put("imgAsBase64", imageBase64Str); it may work.
However you need to consider that this solution won't work for many email clients. According to this link https://www.campaignmonitor.com/blog/email-marketing/2013/02/embedded-images-in-html-email/ Base64 embedded images are not supported on a few major email clients, web and standalone, including Gmail and Outlook. Given that they are the most common email clients you don't want to deliver a solution that doesn't work on them or most of your users are gonna be unhappy.
IMO your best bet is to host the images in a server and use fully qualified URLs in your freemarker template.
An alternative is using the attachment and reference them in the html source as explained here: https://stackoverflow.com/a/36870709/2546299 but it require changes on the way the emails are sent (need to add the attachments) so it may not be suitable for your case.
If I have a HTML String object, using Selenium in Java, how can I get the browser to open that String as a HTML page? I have seen this done before but I don't remember the format that the URL needs to be.
For this example, let's say the string is :
<h2>This is a <i>test</i></h2>
I looked through this page and couldn't find the answer but I might be overlooking it. For example I tried this URL and it didn't work for me:
data:<h2>This is a <i>test</i></h2>
Here is a link for documentation http://en.wikipedia.org/wiki/Data_URI_scheme. You need to specify MIME-type of data. Try data:text/html,<h2>This is a <i>test</i></h2>
I am trying to send a dynamic link via email with the following code.
Message messageSSL = new MimeMessage(session);
int hash=1000;
String content="click here";
messageSSL.setContent(content, "text/html");
However, i have failed to generate a dynamic link.The output in the mail is in the plain text format.
Output (In the mail):
click here
Even though, the following code works and generates a link called "click here".
String content="click here";
Thanks!!
I think the problem is with backward slash. We should be using forward slash in urls. Please change and try it.
The Apache Commons Email library has some useful classes that take care of the low-level details for stuff like making HTML email work properly. Check it out:
http://commons.apache.org/proper/commons-email/
can you please enclose the link by html tag and try once.
String content="<html><body>click here </body></html>";
i am using same library and working fine for me.
please check below thread
How Can I put a HTML link Inside an email body?
i have an account register function, after user inputted personal data, an confirm email will be sent to that customer with a generated link. The problem is that: because the link is too long, it is broken into two lines (The second line is from character 76) and the second line does not belong the the first line (User cannot click on the whole link). I think this problem may come from the word wrap or something like that
In Outlook Express, under menu->Tools->Options->Send->HTML setting, we can set number of characters that the email content should be wrapped in each line by changing the value. Is there any way to set this function using core Java Mail?
Thank you in advance.
Word wrapping is done by the viewer (i.e. Outlook Express) not when sending email. I would guess that you are sending plain text emails and relying on the viewers to try and identify that it contains links. Try sending HTML mail and using ''
No, JavaMail is a library allowing you to send/receive email through Java. It is not an application like Outlook/Outlook Express or Thunderbird for that matter.
That said, you can write code that does the formatting before it invokes JavaMail to send the email out.
First, you can't set a setting in java mail to change a client's formatting.
Second, while my solution might not be the best answer to the question. It should help with the problem you are having.
Before adding your link into the body of the mail make sure you;
Put the link on a new line. "\n" ;)
Make a little method using URL shortening API like bitlyj for bit.ly to shorten the URL. Add the shortened link and walla!
msg.setContent("This is an example of adding a shortened URL\n"
+ shortLink("http://www.longlink.com")
+ "\n", "text/plain");
public String shortLink(String link) {
Url url = as("Username", "APIKey").call(shorten(link));
return url.getShortUrl();
}
Using this approach you shouldn't have any issues with word wrap stuff.
