Forgive me for posting a topic that seems to be answered already in this forum. I am not able to correct this fault using the information provided in this form and FAQ sections.
This is a basic tutorial example of a struts project I have created. It consist of one jsp, one Form and Action class. However, typing in the URL http://localhost:8080/strutsproject I recieve the following fault: [code] java.lang.NullPointerException: Module 'null' not found. org.apache.struts.taglib.TagUtils.getModuleConfig(TagUtils.java:755) org.apache.struts.taglib.TagUtils.computeURLWithCharEncoding(TagUtils.java:364) org.apache.struts.taglib.TagUtils.computeURLWithCharEncoding(TagUtils.java:285) org.apache.struts.taglib.logic.RedirectTag.generateRedirectURL(RedirectTag.java:289) org.apache.struts.taglib.logic.RedirectTag.doEndTag(RedirectTag.java:268) org.apache.jsp.index_jsp._jspx_meth_logic_005fredirect_005f0(index_jsp.java:115) org.apache.jsp.index_jsp._jspService(index_jsp.java:87) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:374) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:337) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) [/code] What I have done to correct this problem myself: 1. Verify all the dependent jar files are in the lib directory within the war file. 2. I reviewed the struts-config.xml file. Here is my struts 1.3.8 config file.

I do not see it in the Tomcat logs or within the console stating the ActionServlet init() has been called. I have used the blank Struts war file that comes with the distribution. I can get this project to work. I have compared the libraries and the two projects are the same. I have read the JavaRanch forum for suggestions and FAQ. I can not see where this error is coming from..... Any suggestions would be greatly appreciated. This is my first Struts application I am accomplishing from the beginning, so I am a little rusty..... Thank you in advance for taking the time in reading my post. Any comments would be greatly appreciated. -- View this message in context: http://www.nabble.com/java.lang.NullPointerException%3A-Module-%27null%27-not-found.-tp20228347p20228347.html Sent from the Struts - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
