Overview

The HTTP Status 500 error can be seen when the Swivel Administration console encounters a problem and may be for a variety of reasons. This document is to help troubleshoot those issues.

Prerequisites

Swivel 3.x

Symptoms

The following error message may be seen in the browser, the message may vary according to the problem encountered.

HTTP Status 500 - type Exception report message description The server encountered an internal error that prevented it from fulfilling this request. exception org.apache.xmlbeans.impl.values.XmlValueDisconnectedException org.apache.xmlbeans.impl.values.XmlObjectBase.check_orphaned(XmlObjectBase.java:1212) com.swiveltechnologies.xmlconfig.impl.LookupImpl.isSetValue(Unknown Source) com.swiveltechnologies.pinsafe.server.config.ConfigurationListImpl.getLookup(ConfigurationListImpl.java:470) com.swiveltechnologies.pinsafe.server.ui.ConfigurationEditor.setListElement(ConfigurationEditor.java:647) com.swiveltechnologies.pinsafe.server.ui.ConfigurationEditor.executePost(ConfigurationEditor.java:317) com.swiveltechnologies.pinsafe.server.ui.InterfaceServlet.doPost(InterfaceServlet.java:265) javax.servlet.http.HttpServlet.service(HttpServlet.java:637) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) filters.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:125) note The full stack trace of the root cause is available in the Apache Tomcat/6.0.36 logs. Apache Tomcat/6.0.36

Solution

A good place to start looking for such issues is in the Tomcat logs, see the Tomcat logs section under Troubleshooting_Files_FAQ

Known causes of this issue are given below:

Transport deletion in Swivel 3.9.2

When a transport is deleted in Swivel 3.9.2 and a new one created an Error 500 message may be produced.

org.apache.xmlbeans.impl.values.XmlValueDisconnectedException org.apache.xmlbeans.impl.values.XmlObjectBase.check_orphaned(XmlObjectBase.java:1212) com.swiveltechnologies.xmlconfig.impl.LookupImpl.isSetValue(Unknown Source) com.swiveltechnologies.pinsafe.server.config.ConfigurationListImpl.getLookup(ConfigurationListImpl.java:470) com.swiveltechnologies.pinsafe.server.ui.ConfigurationEditor.setListElement(ConfigurationEditor.java:647) com.swiveltechnologies.pinsafe.server.ui.ConfigurationEditor.executePost(ConfigurationEditor.java:317) com.swiveltechnologies.pinsafe.server.ui.InterfaceServlet.doPost(InterfaceServlet.java:265) javax.servlet.http.HttpServlet.service(HttpServlet.java:637) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) filters.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:125)

To overcome this issue the <path to Transient data>/conf/config.xml file can be edited, for an appliance this file is located in:

/home/swivel/.swivel/conf/config.xml

Backup the file before editing.

Stop Tomcat

Edit the file and look for the transport to be removed. Look for and remove <element readonly="true"> to </element> inclusively

Example:

<element readonly="true">

<string name="id" readonly="true" maxlength="32">

<value>TRANSPORT NAME TO REMOVE</value>

</string>

<string name="class" readonly="true">

<value>com.swiveltechnologies.pinsafe.server.transport.transport</value>

</string>

<long name="stringcount"/>

<boolean name="copytolalert"/>

<lookup name="alertgroup" lookup="groups" blank="repository_groups_no_group"/>

<lookup name="group" lookup="groups" blank="repository_groups_no_group"/>

<lookup name="attribute" lookup="attributes" blank="repository_attributes_none">

<value>phone</value>

</lookup>

</element>

Also look for the following

<group name="TRANSPORT NAME TO REMOVE" generated="true"> to </group> inclusively

Save the file

Start Tomcat
