How to build a plugin or bean

[Jan Blok]

Some really nice tutorials produced by Patrick Talbot, about how to build a plugin or bean.

[Foobrother]

Downloaded, used and approved

Very nice indeed!

Thx Patrick.

[JuanMartin]

Many Many thanks, Patrick

It´s nice.

I built the slider bean as the second tutorial, and it seems to be fine. I put it in the jar file in the servoy\applications_server\beans folder and restarted servoy, but it does not show in the "Place beans" list.

Any ideas?
Thanks,
Larry Long

Larry,

Does your jar file have a MANIFEST.MF where your bean class is marked as such?

Rob

Code: Select all

Manifest-Version: 1.0

Name: net/stuff/servoy/beans/slider/ServoySlider.class
Java-Bean: True

[lalong]

Yes I do...

Manifest-Version: 1.0
Name: servoy/beans/slider/ServoySlider.class
Java-Bean: True

-Servoy is located on my d:\servoy6 folder.
-The jar file is named servoy_slider.jar and is in the servoy6\application_server\beans folder
-The package is named ServoySlider.

Does the manifest "Name:" info need to match up to the file name/location?

[rgansevles]

Larry,

With which version has the bean been (echo?) compiled?
If a bean is compiled with java 6 and developer is running with java 5 it also does not show up.

Rob

[lalong]

How do I tell for both instances?

[ptalbot]

In Eclipse check the preferences of the project, the one you are looking for is "Java compiler" and the "JDK Compliance'"
In Servoy, simply launch a debug client then click on the "Help > About..." menu, the dialog will tell you which Servoy and Java version you are running.

But have you checked the servoy_log.txt for any exception that might have prevented your bean from showing up?

[lalong]

Client - Java 1.7
JAR - JaveSE 1.6 (but it recompiled with 1.7 with same results)

My code at bottom...

No servoy_log.txt, but I am finding a log file w/errors in workspace/.metadata/.log

[ptalbot]

From the error log, it seems that you have declared a property you have no access to (probably in your BeanInfo implementation).

Look at your usage of javax.swing.TransferHandler, it might well be that the property you are trying to access is public in one version of Java but is now protected in the one version you are running your bean on.

[lalong]

I did a "clean" and that seems to have taken care of some of the errors...I still have what is shown below.
Any chance it has to do with using 1.7?

There are no more errors related to your bean apparently (only one related to your solution and some Eclipse shortcut conflicts, but that's not a big issue and will not prevent Servoy to work).
Does your bean appear npw when you try to "Place bean..."?

Ah you meant "now"...No it doesn't
