Please use the Trails users mailing list when asking questions about the framework. So, you got your image bytes in the database, then what? I assume you want to show the images on the table. If so, you'd override the columnvalue for Picture property (
http://www.trailsframework.org/Customizing+pages
, "Customizing ObjectTable component") and you'd render an img tag and its src link instead (with a value something like /pictureservice?id=XX). Then, you'd implement a simple Tapestry service that finds the right entity based on the given id and returns the image stream.
The 64K is a database-specific default for a lob field. You can set a different size with a Hibernate annotation, e.g. @Column(length = 1048576)

Hi - I love the trails framework! At last I can
build webapps without ten miles of code.....
I want to add pictures to my app and have got as
far as this:
private byte[]
picture;
@PropertyDescriptor(index=
2,displayName="Pic")
@Lob
public byte[]
getPicture() {
return picture;
}
public void
setPicture(byte[] picture) {
this.picture =
picture;
}
How do a get the picture to display on the page?....and get over the 64k
limit??
Many thanks in advance.....
Cheers TC
