I am trying to Install Appian 7.2 with JBOSS EAP 6.1.0 but after completing all

Hi Rishu, please make sure that you've updated standalone.xml to contain the datasources subsystem. More information can be found here: forum.appian.com/.../Configuring_Relational_Databases

Additionally, ensure that you've added your security domain to standalone.xml as you did with the standalone.xml file for AS7.

Hi Patty, I added the following security domain in standalone.xml
<security-domain name="ds-name-security" cache-type="default">
<authentication>
<login-module code="org.picketbox.datasource.security.SecureIdentityLoginModule" flag="optional">
<module-option name="username" value="WWXDemo"/>
<module-option name="password" value="Br*222271"/>
</login-module>
</authentication>
</security-domain>
</security-domains>

Here password is not encrypted

1. The password should be encoded.
2. Did you replace or add the datasources subsystem for your specific database?

Also, I did update Datasource in Standalone.xml which looks like:
<subsystem xmlns="urn:jboss:domain:datasources:1.1">
<datasources>
<drivers>
<driver name="com.microsoft.sqlserver.jdbc" module="com.microsoft.sqlserver.jdbc">
<xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>

The following error: Access denied: authentication failed, indicates that the credentials used to access the database is wrong. Please make sure the password is encoded and that the security domain, ds-name-security, matches the security domain defined in your appian-ds.xml file.

Patty, Actually my command to execute the SecureIdentityLoginModule class failed. so I could not encode password

My appian-ds.xml loooks like: <?xml version="1.0" encoding="UTF-8"?>
<datasources
xmlns:xsi="www.w3.org/.../XMLSchema-instance"
xsi:noNamespaceSchemaLocation="www.jboss.org/.../datasources_1_0.xsd">
<xa-datasource
jndi-name="jdbc/WWXPrimary_SQLServer2008_Local"
pool-name="WWXPrimarySQLServer2008Local"
use-java-context="false">
<xa-datasource-property name="ServerName">ABCLocal\\SQLExpress</xa-datasource-property>
<xa-datasource-property name="PortNumber">1433</xa-datasource-property>
<xa-datasource-property name="DatabaseName">WWXDemo</xa-datasource-property>
<driver>com.microsoft.sqlserver.jdbc</driver>
<xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class>
<security>
<security-domain>ds-name-security</security-domain>
</security>
<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
<xa-pool>
<min-pool-size>5</min-pool-size>
<max-pool-size>100</max-pool-size>
</xa-pool>
<timeout>
<blocking-timeout-millis>5000</blocking-timeout-millis>
<idle-timeout-minutes>5</idle-timeout-minutes>
</timeout>
</xa-datasource>
</datasources>

On which part did the encoding fail?
For example, I am using a Windows machine, and my executions would be the following:
1. COMMAND: set JBOSS_HOME=<absolute path to \\jboss-as-7.1.1.Final>
MINE: set JBOSS_HOME=C:\\72_install\\bin\\jboss\\jboss-as-7.1.1.Final

2. You can copy and paste this, however ensure that there are no additional spaces when pasting into the command line: set CLASSPATH=%JBOSS_HOME%\\modules\\org\\picketbox\\main\\picketbox-4.0.7.Final.jar;%JBOSS_HOME%\\modules\\org\\jboss\\logging\\main\\jboss-logging-3.1.0.GA.jar;%CLASSPATH%

3. COMMAND: java org.picketbox.datasource.security.SecureIdentityLoginModule <your_unencrypted_datasource_password>
MINE: java org.picketbox.datasource.security.SecureIdentityLoginModule mySecretPassword

The output:
Encoded password: 23f7924b53c68b71a443aebbcfc61fd6df8592078de921bc

For linux, please view the documentation for the keywords necessary to set the variables.
