New subject: [xwiki-dev] Problem when creating a Plugin

13 Feb 2006

Dear XWiki Dev,

I try to create a plugin which should reduce the image size to have a kind of 
thumbnail feature.

To do that I've created a plugin a part of the code is hereunder.

To call the plugin I've added in xwiki.cfg the complete name of the class (and 
also a parameter about the cache size). The plugin uses the cache service. 

At runtime my plugin is set by this code :
Plugin imageplugin = (ImagePlugin) context.getWiki().getPlugin("image", 
context);

But I don't have the cache service working, the attribute imageCache is null. 
It seems that the init method is never called.

Any idea is welcome.

Regards

package com.xpn.xwiki.plugin.image;

public class ImagePlugin extends XWikiDefaultPlugin implements
		XWikiPluginInterface {

	private static String name = "image";

	private XWikiCache imageCache;

	private int capacity = 50;

	private static Log mLogger = LogFactory.getFactory().getInstance(
			ImagePlugin.class);

	public ImagePlugin(String name, String className, XWikiContext context) {
		super(name, className, context);
	}

	/**
	 * Allow to get the plugin name
	 * 
	 * @return plugin name
	 */
	public String getName() {
		return name;
	}

	public void init(XWikiContext context) {
		super.init(context);
		try {
			String capacityParam = context.getWiki().Param(
					"xwiki.plugin.image.cache.capacity");
			capacity = Integer.parseInt(capacityParam);
		} catch (NumberFormatException e) {
		}
		imageCache = new OSCacheCache(capacity, true, "temp/imageCache");
	}

	public void flushCache() {
		if (imageCache != null)
			imageCache.flushAll();
	}
