PQ79606: NULL POINTER EXCEPTION WHEN STARTING APPLICATION USING XERCES ORXALAN

APAR status

• Closed as user error.

Error description

• If you are using an older version of Tomcat this limitation
  might apply. If you are using an older version of Xerces or
  Xalan in the endorsed override, you might get a null pointer
  exception when you startup your application. This exception
  occurs because these older versions do not handle the
  jaxp.properties file correctly.
  

Local fix

• To avoid this situation, use one of the following workarounds:
  -  Upgrade to a newer version of the application that
     implements the latest Java API for XML Programming (JAXP)
     specification (http://java.sun.com/xml/jaxp/index.html).
  -  Remove the jaxp.properties file from /usr/java14/jre/lib
  -  Uncomment the entries in the jaxp.properties file in
     /usr/java14/jre/lib.
  -  Explicitly set the SAX Parser, DocumentBuilder or
     Transformer factory using the IBM_JAVA_OPTIONS environment
     variable. For example:
        set IBM_JAVA_OPTIONS=
            -Djavax.xml.parsers.SAXParserFactory=
             org.apache.xerces.jaxp.SAXParserFactoryImpl
     or
        set IBM_JAVA_OPTIONS=
            -Djavax.xml.parsers.DocumentBuilderFactory=
             org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
     or
        set IBM_JAVA_OPTIONS=
            -Djavax.xml.transform.TransformerFactory=
             org.apache.xalan.processor.TransformerFactoryImpl
  -  Set the system property
     for javax.xml.parsers.SAXParserFactory,
     javax.xml.parsers.DocumentBuilderFactory, or
     javax.xml.transform.TransformerFactory from within your
     application's code. For an example, see the JAXP 1.2
     specification.
