Page History

...

When accessing the webapp without the trailing slash after the context http://localhost:8080/magnoliaAuthor after login the user is presented with a 404 page rather than admincentral.  This behavior is configurable via the mapperContextRootRedirectEnabled and mapperDirectoryRedirectEnabled attributes of the Context which may be used to restore the previous behavior. See Tomcat 9.0.0.M2 in https://tomcat.apache.org/tomcat-9.0-doc/changelog.html.

Oracle WebLogic, IBM WebSphere

commons-lang

When deploying on Oracle WebLogic 12c, there is a version conflict while using commons-lang. Oracle WebLogic-12c is distributed with commons-lang-2.5.jar, JackRabbit with commons-lang-2.6.jar and Magnolia with commons-lang-2.1.jar.

To resolve this issue, modify setDomainEnv.sh of Oracle WebLogic and add commons-lang-2.6.jar to the PRE_CLASSPATH. 

Bouncy Castle

Magnolia uses the Bouncy Castle cryptography package to decode the license key and to secure the activation process. Oracle WebLogic 12c is distributed with bcprov-jdk16-1.45.jar but Magnolia is distributed with bcprov-jdk15on-1.58.jar. This leads to a library version conflict.

Symptom: after inserting valid license key into the Magnolia license form, the error message "License is empty" is displayed.

To resolve, do one of the following:

• Edit setDomainEnv.sh in Oracle WebLogic and add bcprov-jdk15on-1.58.jar to PRE_CLASSPATH or
• Remove bcprov-jdk16-1.45.jar from Oracle WebLogic 12c common libraries.

Google Guava

Magnolia cannot render images stored in dam workspace. Google Guava library is used by the DAM API which is used for working with images.

Symptom:

java.lang.RuntimeException: java.lang.NoClassDefFoundError: Could not initialize class com.google.common.cache.LocalCache

Workaround:

 Modify the weblogic.xml file in your application's WEB-INF folder with the prefer-application-packages  element:

<container-descriptor>
   <prefer-application-packages>
	 <package-name>com.google.common.*</package-name>
   </prefer-application-packages>
</container-descriptor>

Deployment issue with jBPM 6

jBPM 6 cannot be deployed on Oracle WebLogic or IBM WebSphere. jBPM is included in the Magnolia Workflow module. All deployment methods are affected: Administration Console, Oracle WebLogic.Deployer, wldeploy Ant task and autodeploy directory.

Symptom:

weblogic.application.ModuleException: java.lang.ClassNotFoundException: org.jbpm.services.task.lifecycle.listeners.TaskLifeCycleEventListener

Workaround:

Reloading a page causes a 404 error

When you open a page for editing and reload it in the browser, an extra semicolon is added to the URL fragment and the server returns a 404 error. Every subsequent reload adds another semicolon. This issue occurs with older versions of the Tomcat application server. To resolve this issue, upgrade to Tomcat 7.0.47+. See 

Tomcat 8 using BCEL may throw class format exception

Deployment issue with jBPM 6

jBPM 6 cannot be deployed on Oracle WebLogic or IBM WebSphere. jBPM is included in the Magnolia Workflow module. All deployment methods are affected: Administration Console, Oracle WebLogic.Deployer, wldeploy Ant task and autodeploy directory.

Symptom:

weblogic.application.ModuleException: java.lang.ClassNotFoundException: org.jbpm.services.task.lifecycle.listeners.TaskLifeCycleEventListener

Workaround:

1. Deploy an application which doesn't contain Magnolia Workflow with jBPM6, for example Magnolia 5.2.2 or Magnolia 5.3 without the Workflow module.
2. In the deployment target location, replace the deployed webapp with a new webapp that contains workflow with jBPM6

OS X / macOS

Magnolia starts up very slowly

Your Magnolia instance starts up very slowly, noticeably more than before. You may encounter this after upgrading your macOS to Sierra 10.12 or later.

Workaround:

1. Open a terminal and figure out the hostname of your Mac. To get the hostname, use the command hostname.

   Code Block
   language text
   hostname joesLittleMacBookPro.local

   The command returns the hostname of your Mac. In the given example, the hostname is joesLittleMacBookPro.local.
   
   

2. Open the file /etc/hosts with an editor of your choice. You will edit the file in the next step.
   The file belongs to the system user root. Your user must belong to the group admin; otherwise, you cannot save the changes to the file. You will be asked for your password either when opening the file or when trying to save it.
   
   

3. Add these two lines to /etc/hosts:

   Code Block
   language text title /etc/hosts
   127.0.0.1 <hostname> ::1 <hostname>

   In place of <hostname>, use your real hostname.
   Most probably, your hosts file already contains entries starting with 127.0.0.1 and with ::1. Just add the real host name at the end of one line that starts with ::1 and at the end of another line that starts with 127.0.0.1. Make sure to add a space character before the hostname.
   With the given hostname, the two lines would look like this:

   Code Block
   language text title /etc/hosts
   127.0.0.1 localhost joesLittleMacBookPro.local ::1 localhost joesLittleMacBookPro.local

4. Save the file. The system may ask you for your password.

Our default configuration uses the server mode for H2. If you migrate from Magnolia below 5.5.9 in the 5.5 branch or below 5.6.2 in the 5.6 branch and try to initiate a backup call using CLI or REST, it fails because H2 does not allow more than one connection at a time. Configure H2 to run in server mode by adding AUTO_SERVER=TRUE in the URL parameters:
