&lt;h2&gt;Symptoms&lt;/h2&gt;
&lt;p&gt;Installing Appian 18.2 with Weblogic&amp;nbsp;12.2.1.3 results in an error of the following type:&lt;/p&gt;
&lt;pre&gt;&amp;lt;User defined listener com.appiancorp.rdbms.datasource.BusinessDataSourceValidator failed: java.lang.NoClassDefFoundError: Could not initialize class com.appiancorp.suite.SuiteConfiguration.&lt;br /&gt;java.lang.NoClassDefFoundError: Could not initialize class com.appiancorp.suite.SuiteConfiguration at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)&lt;br /&gt;.&lt;br /&gt;.&lt;br /&gt;.&lt;br /&gt;&amp;lt;Info&amp;gt; &amp;lt;ServletContext-/suite&amp;gt; &amp;lt;BEA-000000&amp;gt; &amp;lt;Closing Spring root WebApplicationContext&amp;gt; &lt;br /&gt;&amp;lt;Warning&amp;gt; &amp;lt;HTTP&amp;gt; &amp;lt;BEA-101162&amp;gt; &amp;lt;User defined listener com.appiancorp.rdbms.config.PrimaryDataSourceShutdown failed: java.lang.IllegalArgumentException: appianHome cannot be null.&lt;br /&gt;java.lang.IllegalArgumentException: appianHome cannot be null.&lt;/pre&gt;
&lt;h2&gt;Cause&lt;/h2&gt;
&lt;ol&gt;
&lt;li&gt;This issue has been reported to the Appian Product Team. The reference number for this issue is&amp;nbsp;&lt;strong&gt;AN-109591&lt;/strong&gt;.&lt;/li&gt;
&lt;li&gt;This issue may also occur&amp;nbsp;if the &lt;strong&gt;suite.ear&lt;/strong&gt; has been customized and the location of the file has been modified in the process.&amp;nbsp;This&amp;nbsp;affects&amp;nbsp;the absolute paths set within the &lt;strong&gt;suite.ear&lt;/strong&gt; directory leading to the observed issue.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;Action&lt;/h2&gt;
&lt;ol&gt;
&lt;li&gt;Instead of deploying Appian to a Managed Server in Weblogic, deploy Appian to the default AdminServer.&lt;/li&gt;
&lt;li&gt;Ensure that the customization does not modify the location of &lt;strong&gt;suite.ear&lt;/strong&gt;.&lt;/li&gt;
&lt;/ol&gt;
