Hi, I am trying to install 7.9 version and keep getting this permissi

I tried that....but still keep getting the same access denied error....I think the problem is in my standalone.xml file where I declared my datasources.....I am just gonna show the code section here:

<datasource jndi-name="java:jboss/datasources/AppianPrimaryDS" pool-name="ds-name-security-primary" enabled="true" use-java-context="false">
<connection-url>jdbc:mysql://localhost:3306/appian72primary?useOldAliasMetadataBehavior=true</connection-url>
<driver>h2</driver>
<security>
<user-name>root</user-name>
<password>79ba31e7dd57513d6cf3b03f66c6c6f8</password>
</security>
</datasource>
<datasource jndi-name="java:jboss/datasources/AppianBusinessDS" pool-name="ds-name-security-business" enabled="true" use-java-context="false">
<connection-url>jdbc:mysql://localhost:3306/appian72business?useOldAliasMetadataBehavior=true</connection-url>
<driver>h2</driver>
<security>
<user-name>root</user-name>
<password>79ba31e7dd57513d6cf3b03f66c6c6f8</password>
</security>
</datasource>

Please tell me if there is anything wrong in here, particularly in the connection-url section....it had something weird by default in the beginning which I changed to this URL definition now....but the access denied error was there before also when that weird thing existed...so it just didn't happen because of me changing the definition of this thing(connection-url).....Also I am attaching server.log...
