how to fix the java.lang.AbstractMethodError: org.apache.xerces.dom.DeferredElementNSImpl.getTextContent()Ljava/lang/String;

Question

This is the stacktrace I get when I run my application:

Exception in thread "Thread-3" java.lang.AbstractMethodError: org.apache.xerces.dom.DeferredElementNSImpl.getTextContent()Ljava/lang/String; at org.apache.poi.openxml4j.opc.internal.unmarshallers.PackagePropertiesUnmarshaller.readElement(PackagePropertiesUnmarshaller.java:146) at org.apache.poi.openxml4j.opc.internal.unmarshallers.PackagePropertiesUnmarshaller.loadCreated(PackagePropertiesUnmarshaller.java:162) at org.apache.poi.openxml4j.opc.internal.unmarshallers.PackagePropertiesUnmarshaller.unmarshall(PackagePropertiesUnmarshaller.java:124) at org.apache.poi.openxml4j.opc.OPCPackage.getParts(OPCPackage.java:713) at org.apache.poi.openxml4j.opc.OPCPackage.open(OPCPackage.java:275) at org.apache.poi.ss.usermodel.WorkbookFactory.create(WorkbookFactory.java:209) at org.apache.poi.ss.usermodel.WorkbookFactory.create(WorkbookFactory.java:168) at Snomed.Snomed.ImportManualMappingUtility.importmanualmappingdata(ImportManualMappingUtility.java:191) at Snomed.Snomed.ImportManualMappingUtility.importSnomedRun(ImportManualMappingUtility.java:128) at Snomed.Snomed.ImportManualMappingUtility.run(ImportManualMappingUtility.java:100)

When I debug the java that contains the ImportManualMappingUtility class I get an error at the following line:

Workbook workbook = WorkbookFactory.create(new FileInputStream(loadFileConcept));

How can I fix this problem? I believe it is a problem related to xerces jar file; does it?

i tried removing all the xerces files from the webinf /lib folder but that is resulting in some other error!!! plz help?? — Vignesh Swaminathan, Jun 27 '18 at 19:50
Should be xerces:xercesImpl:jar:2.11.0. Try to download from here and put in WEB-INF/lib folder: http://central.maven.org/maven2/xerces/xercesImpl/2.11.0/xercesImpl-2.11.0.jar — Pavel Molchanov, Jun 27 '18 at 20:07
You may need xml-apis:xml-apis:jar:1.4.01 as well: http://central.maven.org/maven2/xml-apis/xml-apis/1.4.01/xml-apis-1.4.01.jar — Pavel Molchanov, Jun 27 '18 at 20:08
currently there is xerces-1.2.3, xerces-2.4.0 xercesImpl-2.6.2 xercesImpl-2.8.1 — Vignesh Swaminathan, Jun 27 '18 at 20:13
