I have worked with servlets and java in a different environment before. This is a new environment for me . We just installed Oracle 9ias and Oracle portal. I am very new to soap and Apache Axis. I was able to compile the code in jdeveloper.

Among the things there: "You should also have an application server or servlet engine and be familiar with operating and deploying to it" (that would be OAS9i) "servlet engines are supported, provided they implement version 2.2 or greater of the servlet API" (I assume OAS9i supports 2.2 or 2.3) "Axis client and server requires Java 1.3 or later" (JDeveloper will install a JDK, hopefully this recent) And finally >>>> A lot of problems with Axis are encountered by people who are new to Java, server-side Java and SOAP. While you can learn about SOAP as you go along, writing Axis clients and servers is not the right time to be learning foundational Java concepts, such as what an array is, or basic application server concepts such as how servlets work, and the basics of the HTTP protocol. Things you need to know before writing a Web Service: Core Java datatypes, classes and programming concepts. What threads are, race conditions, thread safety and sychronization. What a classloader is, what hierarchical classloaders are, and the common causes of a "ClassNotFoundException". How to diagnose trouble from exception traces, what a NullPointerException (NPE) and other common exceptions are, and how to fix them. What a web application is; what a servlet is, where classes, libraries and data go in a web application. How to start your application server and deploy a web application on it. What a network is, the core concepts of the IP protocol suite and the sockets API. Specifically, what is TCP/IP. What HTTP is. The core protocol and error codes, HTTP headers and perhaps the details of basic authentication. What XML is. Not necessarily how to parse it or anything, just what constitutes well-formed and valid XML. Axis and SOAP depends on all these details. If you don't know them, Axis (or anyone else's Web Service middleware) is a dangerous place to learn. Sooner or later you will be forced to discover these details, and there are easier places to learn than Axis. If you are completely new to Java, we recommend you start off with things like the Java Tutorials on Sun's web site, and perhaps a classic book like Thinking in Java, until you have enough of a foundation to be able to work with Axis. It is also useful to have written a simple web application, as this will give you some knowledge of how HTTP works, and how Java application servers integrate with HTTP. <<<< Scott Nichol Do not send e-mail directly to this e-mail address, because it is filtered to accept only mail from specific mail lists. ----- Original Message ----- From: "Secka-Jallow, Dibor" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, February 26, 2004 4:14 PM Subject: RE: Problem in knowing which directory to compile and set classpath Would the Apache Axis work with Oracle9iAS using Jdeveloper Dibor Secka-Jallow Web Developer Atlanta Housing Authority [EMAIL PROTECTED] 404-817-7370 -----Original Message----- From: Scott Nichol [mailto:[EMAIL PROTECTED] Sent: Thursday, February 26, 2004 3:52 PM To: [EMAIL PROTECTED] Subject: Re: Problem in knowing which directory to compile and set classpath Given the errors you are receiving, it appears your environment is not properly configured to use the command-line compiler, nor to run Tomcat, for that matter. Since you do not normally compile from the command line, I would recommend you not try now and use JDeveloper (which I assume you use regularly). As for Tomcat, if you have 9iAS, why do you want to use Tomcat?

Are you trying to run javac from the command line, or are you using the JDeveloper IDE? Since you have installed JDeveloper, I would think you would want to use that. You will have to add the Axis jars to the classpath JDeveloper uses for compiling.
