[dbforms] NullPointerException (newbie)

Wed, 13 Jul 2005 08:34:28 -0700

Hello all, I started to use this tool today, but when I tried to use it, I got a NullPointerException, this is the root cause:

java.lang.NullPointerException
	org.dbforms.taglib.DbFormTag.setTableName(DbFormTag.java:904)
	org.apache.jsp.index_005fclient_005fgroup_jsp._jspService(org.apache.jsp.index_005fclient_005fgroup_jsp:147
)
	org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
	org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:322)

	org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:291)
	org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
	org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter
(MonitorFilter.java:362)

this is my dbforms-config.xml:

<dbforms-config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:noNamespaceSchemaLocation='file:/C:/Documents and Settings/cbracho/My Documents/alterity/LADW/web/WEB-INF/dbforms-
config.xsd'>
  
  <dbconnection name = "java:comp/env/jdbc/ladw" isJndi = "true"/>
  <table name="CAT_CLIENT_GROUP">
    <field name="CAT_GROUP_NUM" fieldType="int" isKey="true"/>

    <field name="CAT_GROUP_NAME" fieldType="varchar"/>
    <field name="CAT_GROUP_TYPE" fieldType="varchar"/>
    <field name="CAT_GROUP_LOCAL_GROUPING" fieldType="varchar"/>

  </table>

</dbforms-config>
