Return image asset from onActivate
How do I get an input stream from an injected asset on my page?
The activation context is which image to use, so I want to stream one asset
or the other.
@Inject
@Path( "context:/images/myimage1.png")
private Asset myImageLogo1;
@Inject
@Path( "context:/images/myimage2.png")
private Asset myImageLogo2;
StreamResponse onActivate( String logoName ) {
if ( "logo1".equals( imageName ) {
return new StreamResponse() {
public String getContentType() {
return "image/png";
}
public InputStream getStream() throws IOException {
return ????? stream from myImageLogo1 ????
}
public void prepareResponse( Response response ) {
// Nothing needed.
}
};
}
else { // use image 2
}
}

Re: Return image asset from onActivate
Posted by "ross.efi" <ro...@att.net>.
I figured it out on my own. The ???? section below just needs to be replaced
with
public InputStream getStream() throws IOException {
return myImageLogo1.getResource().openStream()
}
Works great!
