Info

Not all the questions on this page are directly related to Canvas deployment, e.g. questions on Oracle database. Some of these questions were asked by participants during the Canvas training sessions. We have answered those here for the larger benefit of the Canvas Developer community.

titleWhat are the changes to be done when context root of the application is changed?

Let’s assume that the following are the details of the application: 

  • DATA_SOURCE_NAME : DliteCTDS
  • SCHEMA_NAME : CT_MIG
  • SCHEMA_NAME_PWD : CT_MIG
  • CONTEXT_ROOT : dliteweb
  • WAR_NAME : dliteweb
  • WORK_FOLDER : D:/Canvas19/dliteweb

As a sample reference, the following steps indicate the changes required for the JBoss app server and Oracle database environments. For other app server and database combinations, appropriate changes need to be done in the relevant files. 
Context Root changes

1. In the application WAR, in the JBoss folder, specify the context root in the \WEB-INF\jboss-web.xml file, as shown in the following code snippet:

Code Block
languagexml
<context-root> <CONTEXT_ROOT> </context-root>
<!-- For example -->
<context-root> dliteweb </context-root>

2. In the CTResources.jar, in the ....\Ctweb\Dependencies\Canvas\CTResources.jar\CanvasApplicationContext.json file, specify the context root, as shown in the following code snippet:

Code Block
languagebash
{
	"contextRoot": "<CONTEXT_ROOT>",
	"applicationId": "MODELHOUSE",
	"displayName": "CTWEB",
	"isService": "Y"
}
# For example
{
	"contextRoot": "dliteweb",
	"applicationId": "MODELHOUSE",
	"displayName": "CTWEB",
	"isService": "Y"
}

3. In the CtwebResource.jar, in the ....\Ctweb\CtwebResources\src\main\resource\Ctwebsecurityconfig.properties file, specify the default context root, as shown in the following code snippet: 

Code Block
languagexml
DEFAULT_CONTEXT_ROOT=/<CONTEXT_ROOT>
ALL_CONTEXT_ROOTS=<CONTEXT_ROOT>
<!-- For example -->
DEFAULT_CONTEXT_ROOT=dliteweb
ALL_CONTEXT_ROOTS=dliteweb

4. In the CtwebResource.jar, in the ....\CtwebResources\src\main\resource\Ctwebexportconfig.properties file, specify the context path, as shown in the following code snippet:

Code Block
languagexml
SESSION_TIMEOUT_URL=/<CONTEXT_ROOT>/index.jsp 
CONTEXT_PATH=/<CONTEXT_ROOT>
<!-- For example -->
SESSION_TIMEOUT_URL=dliteweb/index.jsp 
CONTEXT_PATH=dliteweb

JNDI Data source name change

1. In the CtwebResource.jar, in the ....\CtwebResources\src\main\resource\Ctwebdatabaseconfig.properties file, specify the JNDI data source name, as shown in the following code snippet:

Code Block
languagexml
CT_FW_DATASOURCE=java:/<DATA_SOURCE_NAME>
CT_FW_FILEIMPORT_DATASOURCE=java:/<DATA_SOURCE_NAME>
<!-- For example -->
CT_FW_DATASOURCE=java:/DliteCTDS 
CT_FW_FILEIMPORT_DATASOURCE=java:/DliteCTDS

2. In the application WAR, in the JBoss folder, specify the JNDI data source name in the ..../standalone/configuration/standalone.xml file, as shown in the following code snippet:

Code Block
languagexml
<datasource jndi-name="java:jboss/datasources/<DATA_SOURCE_NAME>" pool-name="<DATA_SOURCE_NAME>" enabled="true">
     <connection-url>jdbc:oracle:thin:@10.12.25.28:1521:SIR13714</connection-url>
     <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
     <driver>OracleJDBCDriver</driver>
     <security>
         <user-name><SCHEMA_NAME></user-name>
         <password><SCHEMA_NAME_PWD></password>
     </security>
</datasource>
<!-- For example -->
<datasource jndi-name="java:jboss/datasources/DliteCTDS" pool-name="DliteCTDS" enabled="true">
     <connection-url>jdbc:oracle:thin:@10.12.25.28:1521:SIR13714</connection-url>
     <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
     <driver>OracleJDBCDriver</driver>
     <security>
         <user-name>CT_MIG</user-name>
         <password>CT_MIG</password>
     </security>
</datasource>

3. In the application WAR, in the JBoss folder, specify the JNDI data source name in the \WEB-INF\jboss-web.xml file, as shown in the following code snippet:

Code Block
languagexml
<resource-ref>
   <res-ref-name>jdbc/CTwebCanvasDataSource</res-ref-name>
   <jndi-name>java:jboss/datasources/<DATA_SOURCE_NAME></jndi-name>
</resource-ref>
<!-- For example -->
<resource-ref>
   <res-ref-name>jdbc/CTwebCanvasDataSource</res-ref-name>
   <jndi-name>java:jboss/datasources/DliteCTDS</jndi-name>
</resource-ref>

Work Folder Changes

1. In the CtwebResource.jar, in the ....\CtwebResources\src\main\resource\CtwebImplementation.properties file, specify the work folder and centralized work folder paths, as shown in the following code snippet:

Code Block
languagexml
CT_WORK_FOLDER_PATH=<WORK_FOLDER>                
CT_WORK_CENTRALIZED_FOLDER_PATH=<WORK_FOLDER>   
<!-- For example -->
CT_WORK_FOLDER_PATH=D:/Canvas19/dliteweb                
CT_WORK_CENTRALIZED_FOLDER_PATH=D:/Canvas19/dliteweb

2. Specify the Web Application Resource (WAR) file name of the application in build.xml file, as shown in the following code snippet: 

Code Block
languagexml
<property name="WAR_FILE_NAME" value="${DIST_ROOT}/<WAR_NAME>.war" />
<!-- For example -->
<property name="dliteweb" value="${DIST_ROOT}/dliteweb.war" />

titleConnection timeout issue while deploying application on JBOSS

Solution: Add following entry in the standalone.xml file:

Code Block
languagexml
linenumberstrue
<system-properties>
         <property name="jboss.as.management.blocking.timeout" value="600"/> 
  </system-properties>

titleApplication deployment fails when setting up in a new environment

Check for the following pattern in the error logs:

Code Block
linenumberstrue
java.lang.ExceptionInInitializerError
at java.lang.J9VMInternals.ensureError(J9VMInternals.java:148)
at java.lang.J9VMInternals.recordInitializationFailure(J9VMInternals.java:137)
at io.bit3.jsass.Compiler.<init>(Compiler.java:40)
at com.intellectdesign.canvas.web.themes.ThemeConfig$CssConfig.convertScssFileToCssFie(ThemeConfig.java:817)

Solution: The SASS Java library does not support AIX operating system and hence the issue. This issue can be solved by performing the SASS compilation while generating the application WAR. Go through the following links to find samples of the ANT targets that must be included in the build file to perform the SASS compilation:

titleApplication is not getting deployed

Check for the following pattern in the error logs:

Code Block
linenumberstrue
SEVERE: [com.intellectdesign.canvas.config.ConfigurationManager] [CTCOM00095] : Error while initializing configuration

Solution: This pattern will be present in the CanvasConfig_<yyyyMMddkkmmss>_<appServerName>_<applicationName> in case there is an error while initializing the configuration required for CT. At the end of the stack trace check the root cause mentioned in the “Caused by: " section.
