[ZoomChart in a production environment]

 Hi -

How would you recommend deploying the ZoomChart sample provided in a production environment?  The sample provided uses scriptlets inside a jsp, but this will fail if the web server needs to serialize the session.  In other more explicit words, the session contains a reference to the inner class (the UserCallbackEventHandler), which keeps a reference to its container class, which contains a reference to a ChartServer, which is not serializable.  The web server will serialize sessions in production environments when memory is running low.

At the moment, this is preventing us from considering deployment on a production level...I had also written a post asking if there was a flash version of the zoomchart (this feature is highly sought after by our customers).

[how to create chart fx with flash format]

 Hi -

 I was wondering if there might be a flash version of the ZoomChart?  Would love to handle all of the user control client side, if possible.  Thanks!

[ChartFX open file limit on the server]

Hi - 

 Is there any answer to this question?  We are looking to deploy ChartFX on a production server, but if this is an ongoing issue, we will not be able to.  Thanks.

[Annotations?]

 Are there any examples allowing the user to modify or edit (or even show the toolbar)?  I can't seem to get it to work (the below code doesn't allow the user to show the toolbar or modify the text annotation):

  annotation.Annotations annots;    annots = new annotation.Annotations();    chart1.getExtensions().add(annots);    annotation.AnnotationText text;    text = new annotation.AnnotationText();    text.setText("This is an Annotation Text2");    text.setTop(120);    text.setLeft(100);    text.setAllowModify(true);    annots.getList().add(((annotation.AnnotationObject)text));    annots.setEnableUI(true); annots.getToolBar();

 Also, later on in the same code snippet, it calls "arrow.Attach(2,0,50.0)", however there is no method "Attach".  I changed it to the lower case "attach".  I wonder how this sample ever ran?

[Annotations?]

 I found it.  It actually resides in com.softwarefx.chartfx.server.annotation. 

 

The code  snippet in the programmer's guide shows the following (and many more lines of code after it):

 

Annotation.Annotations annots;

annots = new Annotation.Annotations();

 .

.

.

I changed the upper cases to lower cases as follows:

annotation.Annotations annots;

annots = new annotation.Annotations();

 That .jar doesn't exist there.  I am actually using chartfx7 (does that affect where it lives?)  (I didn't post to the ChartFX 7 group, since it didn't have an "extenstions" folder to post to.

 I am experimenting with the demo of ChartFX for Java Server.  I've seen a couple of blurbs about annotations and wanted to see its capabilities. Unfortunately, I cannot find the extension.  Where can I find it?  Thanks!

 p.s. I was mostly interested in the annotations the  user can put on the chart and wanted to be able to save them (if possible).
