webtop not starting in Tomcat
I have a customized webtop 6.7SP1 application. After upgrading the application to 6.7 SP2 and deploying it on a new tomcat 7 server, the application does not start. How do I fix this issue and start up the application?
The error displayed is:
SEVERE: Exception starting filter WDKController<br/>java.lang.NullPointerException<br/> at java.util.regex.Pattern.<init>(Unknown Source)<br/> at java.util.regex.Pattern.compile(Unknown Source)<br/> at com.documentum.web.env.WDKController.init(Unknown Source)<br/> at org.apache.catalina.core.ApplicationFilterConfig.initFilter(ApplicationFilterConfig.java:277)<br/> at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:258)<br/> at org.apache.catalina.core.ApplicationFilterConfig.setFilterDef(ApplicationFilterConfig.java:382)<br/> at org.apache.catalina.core.ApplicationFilterConfig.<init>(ApplicationFilterConfig.java:103)<br/> at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:4650)<br/> at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5306)<br/> at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150)<br/> at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:901)<br/> at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:877)<br/> at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:618)<br/> at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:1100)<br/> at org.apache.catalina.startup.HostConfig$DeployDirectory.run(HostConfig.java:1618)<br/> at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source)<br/> at java.util.concurrent.FutureTask.run(Unknown Source)<br/> at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)<br/> at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)<br/> at java.lang.Thread.run(Unknown Source)

The deployment guide states some other configuration that need to be done in Tomcat before app deployment:
- Disable the enablePooling property in web.xml
DA 7.1 also requires, and I believe that some of them are needed for Webtop on Tomcat 7 as well:
- In the file catalina.properties insert: org.apache.jasper.compiler.Parser.STRICT_WHITESPACE=false
- In context.xml modify the Context element adding useHttpOnly="false", like:
<Context useHttpOnly="false">
Check these configurations and tell me if it works.

Thank you for you answer.
The following modification have been made:
- Failover turned off in app.xml
- enablePooling disabled in web.xml
- useHttpOnly="false" in context.xml
- org.apache.jasper.compiler.Parser.STRICT_WHITESPACE=false added to catalina.properties
Tomcat 7.0.29 restarted, work folder cleared, and the error remains in localhost.2015-01-14.log

disable all the components you extend in the custom (or your) layer, then re-enable them one after the other to find which one crashes....

Did you find a solution?
