Error while deploying a .war file

Question

Hi,
I have a one Servlet class, which references two more classes for database
connection. After creating a .war file, I am trying to deploy it on iAS, and I
get the following error:
Failed to deploy web application "MBSServlet". Jar file: /var/tmp/jar61304.tmp
is missing its standard xml descriptor located at WEB-INF/web.xml
I don't know anything about /var/tmp/jar61304.tmp, I don't know where is it picking it up from. And my web.xml is as follows:
<?xml version="1.0" standalone='yes'?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" " " target="_new">http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<servlet>
<servlet-name>MBSServlet</servlet-name>
<servlet-class>MBSServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MBSServlet</servlet-name>
<url-pattern>/MBSServlet</url-pattern>
</servlet-mapping>
</web-app>
Any help!!
thanks!!

Hi,
For a tutorial with source on how to create and deploy a simple quickstart JEE5 JPA enterprise 3-tier application on your Oracle WebLogic 10.3 server - see the following example that uses the EclipseLink JPA provider. You should be able to transition all of your mapping information (the @ManyToOne and table/column overrides and named queries for example) using either JPA via entity annotations or native extensions if you do not want to implement EJB3.
see...

We also have a similar version for Tomcat 6 except the JPA entity beans run outside a container-managed JTA transaction on the web container - for reference.
