Hi, We have being using struts for a while now. We got it running on VAJ 3.5.3 . Also, on Websphere 3.5.3 on NT box. But now when time for actual deployment came ( which is on AIX Box ) , struts is giving a hard time . We are getting following error : [01.08.03 16:12:21:326 EDT] 6a64e3f8 WebGroup A SRVE0091I: [Servlet LOG]: "action: Initializing configuration from resource path /WEB-INF/struts-config.xml" register('-//Apache Software Foundation//DTD Struts Configuration 1.0//EN', 'classloader:/disk1/test/test/struts-example/servlets/org/apache/struts/reso urces/struts-config_1_0.dtd' register('-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN', 'classloader:/disk1/test/test/struts-example/servlets/org/apache/struts/reso urces/web-app_2_2.dtd' register('-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN', 'classloader:/disk1/test/test/struts-example/servlets/org/apache/struts/reso urces/web-app_2_3.dtd' resolveEntity('-//Apache Software Foundation//DTD Struts Configuration 1.0//EN', 'http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd') Resolving to alternate DTD 'classloader:/disk1/test/test/struts-example/servlets/org/apache/struts/reso urces/struts-config_1_0.dtd' Parse Fatal Error at line 5 column -1: External entity not found: "http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd". java.net.MalformedURLException: null: java.lang.NullPointerException at com.sun.xml.parser.Parser.fatal(Parser.java:2817) at com.sun.xml.parser.Parser.externalParameterEntity(Parser.java:2506) at com.sun.xml.parser.Parser.maybeDoctypeDecl(Parser.java:1137) at com.sun.xml.parser.Parser.parseInternal(Parser.java:481) at com.sun.xml.parser.Parser.parse(Parser.java:284) at javax.xml.parsers.SAXParser.parse(SAXParser.java:155) at javax.xml.parsers.SAXParser.parse(SAXParser.java:77) at org.apache.struts.digester.Digester.parse(Digester.java:755) at org.apache.struts.action.ActionServlet.initMapping(ActionServlet.java:1331) at org.apache.struts.action.ActionServlet.init(ActionServlet.java:465) at javax.servlet.GenericServlet.init(GenericServlet.java:258) We completely followed the steps of running the struts example on the Struts apache web site. Also, tried "In the DOCTYPE declaration, change the word PUBLIC to SYSTEM and completely remove the line that reads "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" from web.xml and remove "-//Apache Software Foundation//DTD Struts Configuration 1.0//EN" from struts-config.xml. " step as mentioned there but then it says DTD not registered. We have tried lots of work around but nothing worked till now. Have anyone tried the same & got it working. Please let us know. Struts version used is 1.0 ( final release). Its urgent ! Thanks, in advance Shipra Jain
