Error setting property values; exception is org.springframework.beans.NotWritable

[skamiset]

Hi,

I am new to acegi and trying out a test project. I set up web.xml without any problems and created xml for Acegi also but I keep getting following error.

"Error creating bean with name 'daoAuthenticationProvider' defined in class path resource [com/cma/config/applicationContext-security.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyExcep tion: Invalid property 'authenticationDao' of bean class [org.acegisecurity.providers.dao.DaoAuthenticationP rovider]: Bean property 'authenticationDao' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?"

I am not sure what the problem is, looked on the web for few hours and couldn't figure out. If someone can point me in the right direction I will appreciate it very much. The following is xml.

If you search the web/forums, you will find this error discussed many times in relation to Spring configurations. The key here is

"Invalid property 'authenticationDao' of bean class [org.acegisecurity.providers.dao.DaoAuthenticationP rovider]"

If you look at the code or Javadoc for this class you will see that it has no 'authenticationDao' property:

http://acegisecurity.org/acegi-secur...nProvider.html

You want to use 'userDetailsService' instead.

Your filter chain configuration is also incorrect. Please start by getting the tutorial sample running and building from that as a working example.

Hi Luke thanks for help. I got it working. Could you pls point me how I can find the example tutorial, I downloaded src zip for 1.0.4 but I do not see any folder called example or tutorial.

Thanks in advance.

If I were you I would check out the 1.0.x code tree using

svn co http://acegisecurity.svn.sourceforge.../1.0.x-branch/

(assuming you have subversion command line client installed, otherwise do it through an IDE or other subversion client).

Then follow the description on the web site:

http://acegisecurity.org/building.html

which explains how to run the contacts sample app using the jetty plugin. You can do the same for the tutorial sample app.

There are binary versions in the release builds.
