Brilliant! Thanks David.

I have implemented that with my database & DSN with this in the index.htt:

<%!
class Lot {
String photoPath;
String productDescription;
String buyItNowPrice;
String lotID;

public Lot(String photoPath, String productDescription, String buyItNowPrice, String lotID) {
this.photoPath = photoPath;
this.productDescription = productDescription;
this.buyItNowPrice = buyItNowPrice;
this.lotID = lotID;
}
}
%>
<%!
import java.sql.*;
Map lots = new HashMap();
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:wellsdb");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select PhotoPath, ProductDescription, BuyItNowPrice, LotID from Lot where BuyItNowPrice is not null and PhotoPath is not null");
while (rs.next()) {
String photoPath = rs.getString(1);
String productDescription = rs.getString(2);
String buyItNowPrice = rs.getString(3);
String lotID = rs.getString(4);
lots.put(photoPath, new Lot(photoPath, productDescription, buyItNowPrice, lotID));
System.out.println(photoPath + "\t" + productDescription + "\t" + buyItNowPrice + "\t" + lotID);
}
rs.close();
stmt.close();
con.close();
%>

This outputs the data correctly in the system console:

displayProductImage1.jpg Distressed Teak Coffee Table 456.0000 14
chinesebench.jpg Aqua sofa 87889.0000 1135
LINOCHBK.jpg 2 crystal vases (one chipped) 467.9000 1752

This is my slide.htt code:

<%!
Lot lot = (Lot)lots.get(photoPath);
%>
<ja:if exists="lot">
The filename is <%= lot.photoPath %>.
The description is <%= lot.productDescription %>.
The price is <%= lot.buyItNowPrice %>.
The HTML is <%= lot.payPalHTML %>.
</ja:if>

I get this error when I MAKE ALBUM:

Evaluation error on line 2:

Details:
Sourced file: inline evaluation of: `` Lot lot = (Lot)lots.get(photoPath); ;'' : Typed variable declaration : Undefined argument: photoPath

I can't work out why the slide.htt doesn't know about photoPath?

Thanks :-)

Well, it knows about lot.photoPath, but photoPath is a different thing. I guess you meant fileName there, didn't you?

Ok, I've changed it to filename but it still doesn't know about lot in the slide.htt file. Do I need to re-declare Lot at the top of slide.htt - I tried that and it doesn't seem to work.

In slide.htt the map contents are not being output so I put an else statement in and it is dropping into the else and displaying the text "This is sample text". There are no errors in the system console.

<%!
Lot lot = (Lot)lots.get(fileName);
%>
<ja:if exists="lot">
The filename is <%= lot.photoPath %>.
The description is <%= lot.productDescription %>.
The price is <%= lot.buyItNowPrice %>.
The HTML is <%= lot.payPalHTML %>.
</ja:if>
<ja:else>
This is sample text.
</ja:else>

Can you zip and attach the skin you've been entering this into?

I've now found out that Jalbum's exists test isn't smart enough to handle variables declared within a scriptlet. Only variables declared by Jalbum itself are identified by an if exists test. I'll probaby change this for upcoming versions, but for now, here is a working code. Note also how I've dropped the ! character from your scriptlet. I did that so your scriptlet gets evaluated for every image and not just the first time.

Here is a modified slide.htt:
<%
	Lot lot = (Lot)lots.get(fileName);
%>
<ja:if test="<%=lot != null %>">
  The filename is <%= lot.photoPath %>.
  The description is <%= lot.productDescription %>.
  The price is <%= lot.buyItNowPrice %>.
</ja:if>
<ja:else>
  This is sample text.
</ja:else>

Great! In the next Jalbum version, ja:if exists will work with variables you've declared in scriptlets too.

Hello Michael, I notice that you have a standard license for jAlbum, as you are a professional photographer and are using jAlbum on your website you need a Pro license. You can contact the jAlbum help desk to upgrade your license.

Hi Rob,

I upgraded in May of this year,

"SUPPORT AND UPGRADE PLAN EXPIRES: May 27, 2016"

I do not/did not, use Jalbum for my work (I used Wordpress for that http://www.exquisiteimage.co.uk/) and I retired last year as well,

Regards, Michael,,,,

Hi, your license is a Standard one, not a Pro one. One cannot tell from your website that you are retired, it does not show that, but it does show jAlbum is being used, for example http://www.exquisiteimage.co.uk/8-hour-wedding-in-full/
That page shows you are using Chameleon skin with jAlbum 11.2.4

First, I think it would help David or others help if you could give more details of what is wrong. Are you using Turtle skin, is it a modified skin etc. Referring to help from ten years ago is a big ask of anyone ;) a new post in a suitable forum might get a better response than this old thread.

Your new site still looks like a pro license is needed, it is linking to your defunct(?) site, not just the old page I mentioned. It doesn't matter if the page is new or old, does it, it is still a professional use of jAlbum - just confirming that you have not had the correct license for several years.

A pro license is required if jAlbum is used commercially, not just directly selling images via a shopping cart, e.g. promoting a business.

Hi Rob,

I have now deleted that old page (generated 4 years) ago that used Jalbum (when I did have a pro licence),

As confirmed previous this is 100% for non commercial use

Here is the section I need to do the work with

http://www.moodyimage.co.uk/Personal/index.html

Please escalate this to David as this seems pretty anal !

Thanks,
