Please help! 'Unable to retrieve License info' when trying to log on alfresco after installation, using default admin user

[yunxing]

I just installed Alfresco Community 4.2.f on my server: centos5, tomcat7, jdk 1.7, postgres 9.2. Then when I launched the login page http://myhostname:8080/share/, and entered default logon authentication: username = admin & password = admin, it gives "Your authentication details have not been recognized or Alfresco may not be available at this time." error on the logon page.

Then I went to check the tomcat log (catalina.out), there is only one line of log since tomcat started up: "2014-08-14 14:45:57,924  INFO  [web.site.EditionInterceptor] [http-bio-8080-exec-8] Unable to retrieve License information from Alfresco: 404
"

Does this have anything to do with alfresco license files? I don't have a license file as this is community edition.
Is there a more detailed log I can refer to for debugging this issue?
What can I do to solve this? I am really stuck.

Please help!
Thank you very much!

Have you set the path to JDK successfully?

[yunxing]

yes. I see in catalina.sh, if java_home is not set, it will pick up the default, my default is 1.7

Also I feel confident to say yes, because my previous default of jdk was 1.6, and when i tried to launch alfresco, it didn't launch at all, gave 404 error. Then after I upgraded jdk to 1.7, it finally was able to launch and gave me the log on page.

I'm surprised you have only that error in your logs, normally I would expect something from the /alfresco side of things if you get that error.

What happens when you go to http://myhostname:8080/alfresco/ ?

[yunxing]

going to http://myhostname:8080/alfresco/ gives 404 error…. i have alfresco.war and share.war both in tomcat_home/webapps

The license error is irrelevant.   There should be something in your alfresco.log saying why alfresco is not running.

[yunxing]

thanks. where is alfresco.log located?  under dir.root?

[yunxing]

found it

didn't really understand the error, here i am only copying part of the error, as it's so long.

ERROR [org.springframework.web.context.ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'authorityBridgeTableCache' defined in class path resource [alfresco/cache-context.xml]: Cannot resolve reference to bean 'tenantService' while setting bean property 'tenantService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tenantService' defined in file [/opt/apache-tomcat/webapps/alfresco/WEB-INF/classes/alfresco/mt/mt-context.xml]: Cannot resolve reference to bean 'tenantAdminDAO' while setting bean property 'tenantAdminDAO'

[yunxing]

the end of the error is like:

nested exception is java.lang.RuntimeException: Database connection failed: Cannot load JDBC driver class 'org.gjt.mm.mysql.Driver'

which is strange to me, as in file alfresco-global.properties, I set:

db.driver=org.postgresql.Driver
db.url=jdbcostgresql://localhost:5432/alfresco

but why the error message was saying "mysql.Driver"?
