[xwiki-users] XWiki initialization failed!

Hello! I have successfully installed xwiki on Ubuntu 16.06 Server as a deb package using Java JDK instead of JRE. It seemed to be working fine. I've been able to open xwiki without any problems. Then I want to put /manager app for tomcat7 engine. I used apt-get for this task. Now I can use /manager app, but when I'm trying to open xwiki I get this error: XWiki initialization failed! * Can't find descriptor for the component [role = [interface com.xpn.xwiki.store.XWikiVersioningStoreInterface] hint = [file]] class java.lang.RuntimeException: Failed to load component for type [interface com.xpn.xwiki.store.XWikiVersioningStoreInterface] for hint [file] at com.xpn.xwiki.web.Utils.getComponent(Utils.java:758) at com.xpn.xwiki.web.Utils.getComponent(Utils.java:719) at com.xpn.xwiki.XWiki.initXWiki(XWiki.java:1014) at com.xpn.xwiki.XWiki.initXWiki(XWiki.java:965) at com.xpn.xwiki.XWiki.<init>(XWiki.java:954) at com.xpn.xwiki.internal.XWikiInitializerJob.runInternal(XWikiInitializerJob.java:117) at org.xwiki.job.AbstractJob.runInContext(AbstractJob.java:205) at org.xwiki.job.AbstractJob.run(AbstractJob.java:188) at java.lang.Thread.run(Thread.java:745) Caused by: class org.xwiki.component.manager.ComponentLookupException: Can't find descriptor for the component [role = [interface com.xpn.xwiki.store.XWikiVersioningStoreInterface] hint = [file]] at org.xwiki.component.embed.EmbeddableComponentManager.getComponentInstance(EmbeddableComponentManager.java:401) at org.xwiki.component.embed.EmbeddableComponentManager.getInstance(EmbeddableComponentManager.java:190) at org.xwiki.component.internal.multi.DelegateComponentManager.getInstance(DelegateComponentManager.java:83) at org.xwiki.component.internal.multi.DelegateComponentManager.getInstance(DelegateComponentManager.java:83) at org.xwiki.component.internal.multi.DelegateComponentManager.getInstance(DelegateComponentManager.java:83) at org.xwiki.component.internal.multi.DelegateComponentManager.getInstance(DelegateComponentManager.java:83) at org.xwiki.component.internal.multi.DelegateComponentManager.getInstance(DelegateComponentManager.java:83) at com.xpn.xwiki.web.Utils.getComponent(Utils.java:756) at com.xpn.xwiki.web.Utils.getComponent(Utils.java:719) at com.xpn.xwiki.XWiki.initXWiki(XWiki.java:1014) at com.xpn.xwiki.XWiki.initXWiki(XWiki.java:965) at com.xpn.xwiki.XWiki.<init>(XWiki.java:954) at com.xpn.xwiki.internal.XWikiInitializerJob.runInternal(XWikiInitializerJob.java:117) at org.xwiki.job.AbstractJob.runInContext(AbstractJob.java:205) at org.xwiki.job.AbstractJob.run(AbstractJob.java:188) at java.lang.Thread.run(Thread.java:745) Since I'm completely new to java and servlet system I can't figure it out. Google doesn't give much information about this.
