Hi All,
In a plugin project I want to save and load info from
"plugin.properties" file. This file is placed under the root folder.
Code is like this:
String pluginPath = null;
URL bundleRootURL = TestPlugin.getDefault().getBundle().getEntry("/");
try {
URL pluginUrl = FileLocator.resolve(bundleRootURL);
pluginPath = pluginURL.getPath();
} catch (IOException e) {
}
// get the plugin path such as
// "D:/workspace/TestPlugin/"
pluginPath = pluginPath.substring(1);
Properties prop = new Properties();
String path = pluginPath + "plugin.properties";
InputStream is = new FileInputStream(path);
prop.load(is);
In Running & Debug mode it works well. But when I export the
project to myplugin.jar and place it into Eclipse's plugin folder it
didn't work.
BTW: Loading from the file is for a PreferencePage. I download the
some example source code and found that they all use like this: (in a
PreferencePage)
IPreferenceStore ps = getPreferenceStore();
String s1 = ps.getValue(key1, value1); // for save
...
String s2 = ps.getString(key2); // for load
We can only choose IPreferenceStore for saving & loading? Cann't we
do the same with reading & writting from/into the file in the plugin
project?
Would u please help me with that? Thanks in advance!

The plugin.properties is intended to be a read-only set of
internationalized strings. I think it's best to access it like this so
you'll be sure to get the version that's appropriate for the locale.

After setting in a preference page of Eclipse and restart Eclipse, I

The preference settings are stored using IPreferenceStore, you can get
an instance using the AbstractUIPlugin.getPreferenceStore() method.
The data is stored in the workspace directory in a subdirectory called
".metadata". You may store data by yourself inside a directory you
created for your plug-in or you may use the preference store (no need
to use the preference dialog for this, just store your data in
key/value pairs).

If what I want to load are not simple key/value paris, how to do
that? i.e. I want to read a velocity template like:
<html>
<body>
hi $name,
This is the No. &number letters.
<body>
</html>
As a matter of convenience I want to packed the template into the
plugin jar file. When eclipse load the plugin how can I read from the file?
In most cases the key/value paris that loaded from IPreferenceStore
is enough, but if a special file is needed to read inside the plugin
jar, must we use like this?
IPreferenceStore ps = AbstractUIPlugin.getPreferenceStore();
ps.setValue("template", "<html><body>hi $name,This is the No.
&number letters.<body></html>");

You may create a file in the workspace .metada directory. I'm not
familiar with the API, I believe you will find it in the IResource
surroundings, see IResource.getWorkspace(). You may also use
BundleContext.getDataFile().

To read from the plugins jar you can either use the BundleClassloader
and call one of the *Resource* methods or you may use BundleFile to
get your files.
This is from memory and some brief glances at the API so please be
carefull :-)
