HeadlessException in webapp

Wed Nov 09, 2016 1:13 pm

Hello, guys!
I tried resolve images in Oxygen Webapp 18.1 using custom StyleFilter. I do:

Code: Select all

public void processImage(final Styles styles, final AuthorNode authorNode) {
      ...
      try {
         ...
         final URIContent uriContent = new URIContent(requestUrl, query);
         final StaticContent[] sc = new StaticContent[] { uriContent };
         styles.setProperty(Styles.KEY_MIXED_CONTENT, sc);
      } catch (final Exception e) {
         e.printStackTrace();
      }
   }

Its works, but sometimes I have errors in log and I have broken image links in author mode :

Code: Select all

First image was resolved fine, others - no.

What could be the problem?
Thanks in advance.

Hello,

There's a bug at the moment which causes this issue. It appears to be happening because the URL of the image does not end with an image extension.
As a workaround you can change your StyleFilter and have the URIContent href end with an image extension like this:

Code: Select all

final URIContent uriContent = new URIContent(requestUrl, query + "&extension=.png");


Note: the extension written does not matter, no matter the type of image you load, as long as it's one of the following: "jpg", "jpeg", "png", "gif", "svg".

Let me know if this fixes your issue.

Best,
Gabriel

Hello.

I have problem with rendering svg images in Webapp 18.1.
Image

In text mode:

Code: Select all

<p><image href="thanksgiving-ribbon-blue.svg" id="image_awc_4sn_1z"/></p>


I don't have similiar problems with jpg,png images.

In Style filter I have this code:

Code: Select all

//requestUrl = http://localhost:8888/
//request = webapp_editor?sourceDocPath={path}&destDocPath={file}.svg&clientId=1487849830091_127.0.0.1_8888&extension=.svg

final URIContent uriContent = new URIContent(requestUrl, request);
final StaticContent[] sc = new StaticContent[] { uriContent };
styles.setProperty(Styles.KEY_MIXED_CONTENT, sc);


Using this path requestUrl+request I can see svg image in browser.

How can I resolve this problem?
If it need I can provide more information about problem.

Thanks.
Best Regards,
Aleh

Hello,

The only way to solve this problem would be for your request url path to have a .svg extension.
I registered an issue for this bug and will update this forum post when the fix is available.

Best,
Gabriel

Hello,

I wanted to let you know that in Web Author 19.0 we improved handling of SVG resources. Now there are two approaches to make Web Author serve them with the corrent content-type:
1. Use a .svg extension in the file name
2. Use a query param "?oxycontenttype=svg" in the file URL

Cristian
