Hello Wenling, I've found changing the files in the [dspace] install directory to have `tomcat' for owner and group to side step the problem. Have a look at the catalina.out log file for clues, too.

But I could NOT complete submissions. The problem occurs while submitting an item for the collection. At the last step, once pressing "I grant the License", Internal System error, "The system has experienced an internal error. Please try to do what you were doing again, and if the problem persists, please contact us so we can fix the problem", always shows up. The log file for dspace is as fellowing: Something should be mentioned here. In the dspace.cfg file, email settings were all comment out. That means email settings were not set up at all. Could it be the factor? 03-13 11:11:04,505 ERROR org.dspace.app.webui.servlet.SubmissionController @ Error loading step class'org.dspace.submit.step.CompleteStep': java.lang.NullPointerException at java.util.Hashtable.put(Unknown Source) at org.dspace.core.Email.send(Email.java:267) at org.dspace.workflow.WorkflowManager.notifyGroupOfTask(WorkflowManager.java:898) at org.dspace.workflow.WorkflowManager.doState(WorkflowManager.java:551) at org.dspace.workflow.WorkflowManager.doState(WorkflowManager.java:516) at org.dspace.workflow.WorkflowManager.start(WorkflowManager.java:201) at org.dspace.submit.step.CompleteStep.doProcessing(CompleteStep.java:115) at org.dspace.app.webui.submit.JSPStepManager.doStepStart(JSPStepManager.java:331) at org.dspace.app.webui.submit.JSPStepManager.processStep(JSPStepManager.java:278) at org.dspace.app.webui.servlet.SubmissionController.doStep(SubmissionController.java:404) at org.dspace.app.webui.servlet.SubmissionController.doNextStep(SubmissionController.java:474) at org.dspace.app.webui.servlet.SubmissionController.doStep(SubmissionController.java:420) at org.dspace.app.webui.servlet.SubmissionController.doDSPost(SubmissionController.java:342) at org.dspace.app.webui.servlet.DSpaceServlet.processRequest(DSpaceServlet.java:147) at org.dspace.app.webui.servlet.DSpaceServlet.doPost(DSpaceServlet.java:105) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.dspace.app.webui.filter.RegisteredOnlyFilter.doFilter(RegisteredOnlyFilter.java:98) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:857) at org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:565) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1509) at java.lang.Thread.run(Unknown Source) The following is the email settings in dspace.cfg file ##### Email settings ###### # SMTP mail server # mail.server=smtp.myu.edu # SMTP mail server authentication username and password (if required) # mail.server.username = myusername # mail.server.password = mypassword # SMTP mail server alternate port (defaults to 25) # mail.server.port = 25 # From address for mail # mail.from.address = dspace-nore...@myu.edu # Currently limited to one recipient! # feedback.recipient = dspace-h...@myu.edu # General site administration (Webmaster) e-mail # mail.admin = dspace-h...@myu.edu # Recipient for server errors and alerts # alert.recipient = email-address-here # Recipient for new user registration emails # registration.notify = email-address-here # Set the default mail character set.
