how use <a4j:mediaOutput> for a separate svg file

[mathias°ö°]

hi
i am not sure which attributes for <a4j:mediaOutput> component i must use for link a separate svg file.

<a4j:mediaOutput element="object" uriAttribute="data"
 type="image/svg+xml" ?="http://../images/map.svg" cacheable="false" ></a4j:mediaOutput>

that is not running.

It looks like you want to show the svg image without additional activities, just point to the static file.

If so, you need to use just a standard h:graphicImage. I.e.

<h:graphicImage value="http://../images/map.svg" />

The mime type might be defined in the web.xml:

<mime-mapping>
 <extension>svg</extension>
 <mime-type>image/svg+xml</mime-type>
</mime-mapping>

<a4j:mediaOutput> has two major parts:

createContent - Method call expression to send generated resource to OutputStream.

value - data that is used as a (second) parameter for createContent

So, if you do not want to process svg file in the createContent, you have no reason to use it.

I have the same problem, and that:

doesn't work, cause most browsers can't show .svg in img tags (although they should :/), the solution is to use tags.

My problem is, i can't create a working object tag out of a mediaoutput component. ATM i'm using verbatim tags and normal html object tags but its not really convenient, because i want to generate the svg and change it dynamically.

<f:verbatim>
<object id="svg" data="test.svg" type="image/svg+xml"
width="400" height="300">
</object>
</f:verbatim>

What i tried with <a4j:mediaOutput> is

<a4j:mediaOutput element="object" cacheable="false" session="true"
 createContent="#{testBean.paint}" value="#{testData}" mimeType="image/svg+xml" />

The data created in testBean.paint is legit svg. (tested with some viewers)

editing would be nice :/

the solution is to use tags.

object tags

hi

yes, the <h:graphicImage> can not use for vector graphics (svg).
it´s only use for pixel graphics (bmp, jpg, ...).


but i search a solution for change dynamic url-value (like graphicImage).
in my application i get back a url (to svg file) from server. this url should be change in form after request.

with combination and or can i handle only static values.

Does someone have solution?

As far as I can understand you have a dynamic URL to some SVG data somewhere. You are NOT creating this SVG data. Why just don't use in your case?

hi ishabalov

yes i get back a dynamic SVG-URL, in don´t create this data. Which component do you mean i must using to render this graphic in a frame of result-form?

What about displaying a SVG which is wrapped inside a DOM Docoument Object. Could that be possible that way too?

[henrik.lindberg]

I am guessing here, but it seems that what you are trying to do is to output the SVG content that you obtain by reading the content of URL that you have no control over. If that is the case, why not read the URL, and write it on the IO stream obtained by mediaOutput. The data could be the URL.
i.e. something like

createContent="#{testBean.copyContent}" value="http://somewhere/something.svg" mimeType="image/svg+xml"
