OK, after some trial and error my first impression that an ext plugin would not work because it woud be run later than the time needed, was correct, so I had to change the source code and rebuild using provided ant scripts (thankfully!). Since the http://issues.liferay.com/browse/LPS-4336 link corresponds to an earlier version of Liferay I thought it would be usefull to present an approach. The modification concerns the file com.liferay.portal.dao.jdbc.util.DataSourceFactoryBean of the porta-impl.jar:
[url=http://issues.liferay.com/browse/LPS-4336][/url]
public DataSource createInstance() throws Exception {
Properties properties = _properties;
if (properties == null) {
properties = PropsUtil.getProperties(_propertyPrefix, true);
}
else {
properties = PropertiesUtil.getProperties(
properties, _propertyPrefix, true);
}
Properties defaultProperties = PropsUtil.getProperties(
"jdbc.default.", true);
/**
* Overriding code: begin
*/
Enumeration<string> propEnum = (Enumeration<string>)defaultProperties.propertyNames();
while(propEnum.hasMoreElements())
{
String key = propEnum.nextElement();
if(key.equalsIgnoreCase("password"))
{
/*Property jdbc.default.encrypted.password enables one to define whether the provided password is encrypted or not*/
boolean isEncrypted = GetterUtil.getBoolean(defaultProperties.getProperty("encrypted.password"));
if(isEncrypted)
{
String value = defaultProperties.getProperty(key);
Base64 base64 = new Base64();
byte[] bytesArray = base64.decode(value.getBytes());
value = new String(bytesArray);
/*Set the password property in the property member field since it is the one to be taken into account*/
properties.setProperty(key, value);
}
}
}
/**
* Overriding code: end
*/
PropertiesUtil.merge(defaultProperties, properties);
properties = defaultProperties;
//...
//code continues...
</string></string>
The code part between the two "Overriding code" comments is actually an addition. Nothing was overwritten/removed. The encryption approach follows the one provided in the link of previous post. It is more like an encoding rather than a sophisticated encryption. One can replace with its own encryption choice.
I forgot to add that in this particular case the following fragment of code is sufficient to create an encoding of your db password:
Base64 base64 = new Base64();
byte[] bytesArray = null;
String result = null;
bytesArray = base64.encode(password.getBytes());
result = new String(bytesArray);
result variable contains the encoded password. Print it and assign it to jdbc.default.password property in portal-ext.properties
