ciao ragazzi
sto installando un cms fatto in java, ma al momento dell'installazione mi dà questo problema:
codice:Giving up, unable to start OpenCms. 7: Critical error while loading driver manager. 6: The following critical error occured: at org.opencms.setup.CmsSetupWorkplaceImportThread.run(CmsSetupWorkplaceImportThread.java:209) 32: at org.opencms.setup.CmsSetupWorkplaceImportThread.kill(CmsSetupWorkplaceImportThread.java:118) 31: at org.opencms.main.CmsShell.exit(CmsShell.java:557) 30: java.lang.NullPointerException 29: at org.opencms.setup.CmsSetupWorkplaceImportThread.run(CmsSetupWorkplaceImportThread.java:194) 28: at org.opencms.main.CmsShell.start(CmsShell.java:646) 27: at org.opencms.main.CmsShell.executeCommands(CmsShell.java:818) 26: at org.opencms.main.CmsShell.executeCommand(CmsShell.java:743) 25: ${user}@${project}>java.lang.NullPointerException 24: ${user}@${project}># Turn echo on 23: ... 5 more 22: at org.opencms.db.CmsSecurityManager.init(CmsSecurityManager.java:2711) 21: at org.opencms.db.CmsDriverManager.init(CmsDriverManager.java:4307) 20: at org.opencms.db.generic.CmsProjectDriver.fillDefaults(CmsProjectDriver.java:668) 19: at org.opencms.db.generic.CmsVfsDriver.writeResource(CmsVfsDriver.java:2826) 18: at org.opencms.db.generic.CmsVfsDriver.internalReadParentId(CmsVfsDriver.java:3030) 17: Caused by: org.opencms.file.CmsVfsResourceNotFoundException: Unable to read parent id of resource "[B@d2efa1". 16: at org.opencms.setup.CmsSetupWorkplaceImportThread.run(CmsSetupWorkplaceImportThread.java:155) 15: at org.opencms.main.CmsShell.<init>(CmsShell.java:450) 14: at org.opencms.main.OpenCmsCore.upgradeRunlevel(OpenCmsCore.java:1692) 13: at org.opencms.main.OpenCmsCore.initConfiguration(OpenCmsCore.java:1117) 12: at org.opencms.db.CmsSecurityManager.newInstance(CmsSecurityManager.java:156) 11: at org.opencms.db.CmsSecurityManager.init(CmsSecurityManager.java:2720) 10: org.opencms.main.CmsInitException: Critical error while loading driver manager.
