Developing Scripts in NetBeans
This document describes how to set up NetBeans for OpenOffice.org Scripting and how to write a simple script using NetBeans. You can download the NetBeans IDE from the NetBeans download page.Contents:
Pre-requisites
- Install the OpenOffice.org Scripting module To install this module, shutdown NetBeans and copy the office.jar file to your <NetBeans installation>/modules directory.
- Create a directory somewhere on your machine in which you will develop your scripts.
- Note: The OpenOffice.org Scripting module has been tested with NetBeans 3.4
unoil.jar, ridl.jar, sandbox.jar, jurt.jar, juh.jar
Creating a Parcel Recipe
OpenOffice.org scripts are delivered in Script Parcels. Like OpenOffice.org documents they are zip files. Script Parcels have the .sxp extension. Script Parcels are generated from Parcel Recipes where all of the files that are necessary to create the parcel are put together. To create a new Parcel Recipe:- Right click on your mounted filesystem
- Select New/Office Scripting/Parcel Recipe
- In the New Wizard window that appears enter a name for your Parcel Recipe
- Select a language for your Parcel Recipe from the Initial Script Language dropdown list.
- Click the Finish button to create your Parcel Recipe
Note: To add further empty stub scripts to your Parcel Recipe, right click on the Contents directory and use the New/Office Scripting/Empty Script menu item.
Actions available for Parcel Recipe
If the user right clicks on the parcel directory they should be able to use the following actions:- Compile: Compiles all of the .java files in the Parcel Recipe
- Build: Compiles all of the .java files in the Parcel Recipe. It then searches for valid OpenOffice.org scripts in the language you selected in the Contents directory files and pops up a dialog which allows you to select which Java methods or BeanShell scripts you wish to export as OpenOffice.org scripts. Once you have finish making your selections, it creates a <Parcel Recipe Name>.sxp Script Parcel file in the Parcel Recipe directory. You can configure what files are put into the Script Parcel using the File Filter property. If you script includes any jar files that need to be in the classpath when it is executed you should add them to the Classpath property of your Parcel Recipe.
- Configure: This pops up the Configure dialog, which allows you to select what OpenOffice.org scripts to export. Any changes you make in this dialog will only appear in your Script Parcel after you run Build again.
Actions available for Script Parcels
Script Parcels supports only one action:- Deploy: This will deploy the Script Parcel to an OpenOffice.org Document or to an OpenOffice.org installation. If the Script Parcel already exists in the target, you will be asked whether you want to overwrite.
Note: If you deploy a Script Parcel to an OpenOffice.org installation you need to use the Tools/Scripting Add-on's/Refresh All Scripts menu item for the new script to appear in the Assign Script dialog.
Note: You can also deploy to OpenOffice.org documents within NetBeans using drag and drop or cut and paste.
Actions available for OpenOffice.org Documents
OpenOffice.org Documents are also recognised by NetBeans. Any parcels contained in the document will be displayed as nodes of the OpenOffice.org document. Deleting one of these nodes will remove the Script Parcel from the document. You should ensure that the document is not open in OpenOffice.org before deleting any parcels it may contain. OpenOffice.org documents support the standard Delete, Cut and Copy actions and the following custom actions:- Open: This will open the document in OpenOffice.org using the path
in the Office Settings property to find the OpenOffice.org installation.
If the path to OpenOffice.org is not valid, an error dialog will be popped up informing the user that they need to set their Path to Office Installation property. This setting can be changed by bringing up the Tools/Options dialog and changing IDE Configuration/Server and External Tool Settings/Office Settings
Debugging Java OpenOffice.org scripts in NetBeans
- Follow the instructions at Debugging Java components in NetBeans/Forte for Java to set up your OpenOffice.org installation to allow debugging of the JVM.
- Start OpenOffice.org and run one of your Java scripts. This will make sure the JVM is running.
- Attach to OpenOffice.org JVM using the NetBeans Debug/Start Session/Attach... menu option.
- Load a script source in NetBeans and set up breakpoints using Debug/New Breakpoint... menu option.
- Run the script in OpenOffice.org.
Note: As the BeanShell scripting language does not support debugging it is not possible to debug BeanShell OpenOffice.org scripts from NetBeans. You can however use the Interactive BeanShell scripting menu item under the Tools menu in OpenOffice.org to test BeanShell code. Just enter any BeanShell code and hit the Eval button to execute it.
Troubleshooting
If you encounter problems when developing or deploying scripts in NetBeans, one thing you can try is to move your NetBeans settings directory (.netbeans on UNIX, netbeans in Windows - can be found in your home directory) to another name and restart NetBeans.
The Choose What to Export as Scripts dialog only displays methods which are defined within class files, it will not display methods in class files which are within jar files in the Parcel Recipe.
If you include package directives in the Java source files of your Parcel Recipe, you should ensure that the source files are in the appropriate directories for your package directives. This is because the default NetBeans compiler implementation does not use the -d switch to the Java compiler. As a result class files do not get placed in the appropriate directories and methods in these classes will not appear in the Choose What to Export as Scripts dialog.
There are a couple of workarounds for this problem:
- Use the command line tools
- Set the Target flag in the Tools/Options window under Building/Compiler Types/Internal Compilation
