While restrting server I am getting error as

[ISS.0014.0054C] Error occurred while initializing server: java.lang.NoSuchFieldError: blockStartPos at com.wm.lang.xml.token.BurstBlockInputBuffer.getNext(BurstBlockInputBuffer.java:220) at com.wm.lang.xml.token.WMTokenSource.nextToken(WMTokenSource.java:278) at com.wm.lang.xml.DocumentTreeBuilder.processNextToken(DocumentTreeBuilder.java:66) at com.wm.lang.xml.ElementNodeBase.getFirstChildWm(ElementNodeBase.java:270) at com.wm.util.coder.IDataXMLCoder.decode(IDataXMLCoder.java:363) at com.wm.util.coder.IDataXMLCoder.decode(IDataXMLCoder.java:342) at com.wm.app.b2b.server.util.security.OPMConfig.getConfigData(OPMConfig.java:242) at com.wm.app.b2b.server.util.security.OPMConfig.asPassManConfig(OPMConfig.java:135) at com.wm.app.b2b.server.OutboundPasswordAdministrator.getConfigData(OutboundPasswordAdministrator.java:558) at com.wm.app.b2b.server.OutboundPasswordAdministrator.init(OutboundPasswordAdministrator.java:95) at com.wm.app.b2b.server.OutboundPasswordAdministrator.init(OutboundPasswordAdministrator.java:88) at com.wm.app.b2b.server.Server.run(Server.java:367)

Can anyone please let me know the issue and how to overcome it.

hmmm… is ur IS not coming up?

Yes,server was not coming up.

Later we uninstalled the fix IS_7.1.2_WebSvcsXML_Fix19 and server came up without errors.
