Dear Mr Swinsburg,
I still can't get the log file, so i send you my source code. I hope you will check it and see the problem yourself.
I am using Sakai 2.5.5. if you are using a different version, you can tell me which version you are using, i will change my source and send it again.
These are what i had change in your original profile2 project:
In package org.sakaiproject.profile2.tool.pages: create a new page called "MyHello" --> new files(MyHello.java + MyHello.html).
In tool/src/java: Create two new packages
package org.sakaiproject.profile2.tool.myapi, at this time, this package is using for injecting some gradebookService to use.
package org.sakaiproject.profile2.tool.mysql, at this time, this package is using for doing some querry. i used this to get a LinkedList<String> of all course siteId, and a LinkedList<String> of all course site name.
I create new packages and classes because i tried not to change much in the original source files. With these, the tool deployed successful, but the gradebookService did not work.
Because you told me that it's easier to use the services by injecting them into SakaiProxy. I tried yesterday, and now tomcat can not start up. Hope you can help. Thank you. Feel free to give me any request.
Thanks and regards

Sure, the log should be at c:\tomcat\logs\catalina.out
I'm not sure of the Windows equivalent to 'tail -f catalina.out' which will show you the log messages are they are written to the file. You might need to open it up in a text editor and just send the relevant output from the latest startup failure.
cheers,
Steve

At this time, we are creating a new page in the display screen ( same as My profile, Connections, Search....) this page is using for display all grades of student have had. Whenever he come to this page, he can see all his grades profile. Cause we do not want to change the original project, we created some new class in the package org.sakaiproject.profile2.tool.pages . at this time, we can get a LinkedList<String> of all site id of all course that one user joined and display it on my new page. Cause the siteId is also the gradebookUid, we try to use the GradebookService to get all the Assignment of each site, and at this state we encountered the problem.
