Web Services tutorial - problems executing

I've recently installed jdeveloper onto winXP pro from the jdev9i_902.zip download and installed to D:\jdeveloper. Following the instructions I also installed JDK1.3 to D:\jdk1.3.1_04. I ran the setup for oc4j.
The problem I have is that when I followed the "Publish a stateless Java class as a Web service" tutorial, everything goes well until I run it. The errors produces are (taken from the tcptunnel output):
===========

The main section that concerns me is "Invalid class file format in E:\Program Files\Java\j2re1.4.0\lib\rt.jar(java/lang/Object.class). ", why is using this?
Any feedback on this is appreciated.
Dave

Dave, given the messages returned indicate your configuration is looking at a j2se1.4 directory, I think that is the problem. Neither OC4J or JDeveloper are certified with JDK 1.4. I realize that you have installed 1.3 so my guess is that in following step 8 and 10 of the "Installing and Running Oracle9iAS Containers for J2EE" where it says:
8. Install the J2EE container using the following command: java jar oc4j.jar install
10. Start the J2EE container by issuing the following command: java jar oc4j.jar Show me.
the problem is that the commands were not prefixed with the location of your JDK 1.3 installation and by default picked up the later JDK 1.4. I think you will be able to get around it by running the commands as follows (replacing directory names by your locations):
<jdk1.3_home>\bin\java -jar oc4j.jar -install
<jdk1.3_home>\bin\java -jar oc4j.jar
Your JDeveloper should be fine unless you changed its JDK to also be 1.4; by default it uses its own built-in 1.3 JDK.
Hope this points in the right direction.

Hi Vivek,
This problem occurs when Web Service provider is not reachable , it means the server which provides services to the WSDL is temporally down or not reachable . To check whether the services is reachable , you could paste the WSDL URL in your internet browser , if it opens then problem is with NWDS configuration of proxy else sever is not reachable .
In your case problem is not with NWDS but with server as it looks that it is temprorarly down. To avoid such problem in future you could also store the WSDL file locally on your system and then can import ( obvioulsy you requires at least once to get the WSDL ) . This will help only while modelling the application to run you will require the service provider to be up and runnning
You could use other tutorials to try AWS Model in Web Dynpro .

Dhawal

Web service invocation problem on host hostname and port 8000 protocol : http logical port name : LP_WS_SMDAGENT_MONITORING

hello colleagues,
In the phase Connect Diagnostics dont show the Agent available in SLD, but when go to SLD i have the agents,
Error,
Connect Diagnostics Agent
The table does not contain any data
Agent availables in all SLD
SOAP:1.007 SRT: Unupported xstream found: ("HTTP Code 401 : Unauthorized")
Web service invocation problem on host hostname and port 8000 protocol : http logical port name : LP_WS_SMDAGENT_MONITORING
Thanks

OK, then pls follow below steps;
- Go to step 'Create Users' in solman_setup System Preparation scenario and make sure the user SM_INTERN_WS has a green status. Use the 'Test Login' button to make sure the user is not locked and has correct credentials maintained in solman_setup
- Immediately after checking the user status, navigate to Configure Connectivity->Enable Web Services and execute again the 'Create Logical Ports' automatic activity, in order to propagate the correct credentials to the Logical Port definitions.
- If the above operation is not successful, repeat the two steps above, providing a different user Id in 'Create Users' step, eg SM_INTERN_W1. This will prevent situations where the user gets locked by Logical Ports using an obsolete password.
Let me know the results.
Regards,
Vivek

Unsupported Version error when trying to run Web Services Tutorial example

Hi Azeem.
Check out values specified for JAVA_HOME, PATH and CLASSPATH under environment variable. Was facing the same problem. Changed the values to point to jdk1.5 and it is working now.
BTW.
You don't have to uninstall jdk1.4.
Cheers!!!

Web Services - tutorial w/ invalid links

Has anyone gone thru the
'Automated invocation of a .NET web service' tutorial?
The URL listed in the tutorial
http://hosting001.vs.k2unisys.net/Weather/PDCWebService/WeatherServices.asmx is invalid. Any idea where I find
similar .net web services to complete the tutorial?
Thanks.
Srini

Dave, given the messages returned indicate your configuration is looking at a j2se1.4 directory, I think that is the problem. Neither OC4J or JDeveloper are certified with JDK 1.4. I realize that you have installed 1.3 so my guess is that in following step 8 and 10 of the "Installing and Running Oracle9iAS Containers for J2EE" where it says:
8. Install the J2EE container using the following command: java jar oc4j.jar install
10. Start the J2EE container by issuing the following command: java jar oc4j.jar Show me.
the problem is that the commands were not prefixed with the location of your JDK 1.3 installation and by default picked up the later JDK 1.4. I think you will be able to get around it by running the commands as follows (replacing directory names by your locations):
<jdk1.3_home>\bin\java -jar oc4j.jar -install
<jdk1.3_home>\bin\java -jar oc4j.jar
Your JDeveloper should be fine unless you changed its JDK to also be 1.4; by default it uses its own built-in 1.3 JDK.
Hope this points in the right direction.

Cannot complie the example at Java Web Services Tutorial 1.3,Ch3

Hi all,
At the Java Web Services Tutorial 1.3 Chapter 3, there has an example but I cannot compile!
The is the output of ant:

Would you please give me an idea to solve this problem?
Thanks
Chris

Ok...this is driving me nuts!!!
I am getting the same error (blah blah blah...ListTask cannot be found) and I have looked over the forum and copied over the catalina-ant.jar file into the apache-ant/lib dir. I have also included every path I can think of in the PATH env var and CLASSPATH env var...

pipeline is where my jdk (I have two different versions because two different apps) is and the ref to D:\Ant...is for another app.
CLASSPATH = C:\Program Files\Altova\xmlspy\XMLSpyInterface.jar;C:\jwsdp-1.3\server\lib\catalina-ant.jar;C:\jwsdp-1.3\common\lib
ignore the XMLSpy stuff
please help...thanks ahead of time.

Hi,
Unfortunately, your web service is failing at runtime because JDeveloper (and more specifically, the embedded OC4J) is installed in a directory whose path contains a space character. If you move JDeveloper from "Program Files" to another directory, perhaps "Program_Files", then it'll all go smoothly.
Apologies if this causes you inconvenience.

Alan.

Java Web Services Developer Pack/1.2I would be grateful if someone would point out what I have missed.

Thank you for the reply.
I have jwsdp-1.2 (not 1.3) and the version of Tomcat that was packaged with that is the only one I have.
The complete file structure for the gs application has been built at C:\oracle-xml\jwstutorial12\examples\gs. The directory C:\jwsdp-1.2\work\Catalina\localhost\gs exists but it is empty.
When you mention ant scripts, does that mean build.xml? Is the operation you describe performed in a <target> element? How do I set it up? I could not spot anything in the Ant manual.
I notice that C:\oracle-xml\jwstutorial12\examples\common\targets.xml is not well-formed. It consists of a lot of <taskdef> and <target> elements all at document root level.
Thanks for your help.

About Using Ant in Web Services Tutorial 1.0.1

I downloaded the latest version of the Java Web Services Tutorial 1.0.1 and trying to run the
sa,ple applications from ConvertedApp.java. When I type in "ant build"(ant version is 1.4.1), I
am gettigng the error saying
" Usage is java [options] class ........"
as if implying that the classname is missing somewhere!!
Can anyone please give any clue what might go wrong here?
(I am on Windows 2000).
Thanks

Hello.
For example, build.xml is in the folder:
d:\jwsdp_tutorial\docs\tutorial\examples\gs\build.xml
Then write a bat-file in the same folder that looks like this:
-------------------- BEGIN --------------------
set JAVA_HOME=d:/j2sdk1.4.1

Hi Rajesh,
So when all was said and done, did you get the Google Web Service to work and display correctly? The documentation (tutorial) is ok until it gets to the end (for Displaying results) then it's all but non-existent. I tried going through the tutorial but didn't get this to work.

Example code download for "The JavaTM Web Services Tutorial "

Web page at http://java.sun.com/webservices/docs/1.0/tutorial/doc/Preface.html#63740 describes the follwoing way to get code example
==========================================
If you are viewing this online, you need to download The Java Web Services Tutorial from:
http://java.sun.com/webservices/downloads/webservicestutorial.html
Once you have installed the tutorial bundle, the example source code is in the <JWSDP_HOME>/docs/tutorial/examples directory, with subdirectories for each of the technologies included in the pack.
==========================================
However, following the link, I download file jwsdp-1_5_01-tutorial.zip. But this zip does not contain a docs/tutorial/.. directory.
Any hint? Thanks in advance.

Did you set up the database as described in
http://java.sun.com/webservices/docs/1.0/tutorial/doc/WebApp13.html#69868

Trouble With Web Services Tutorial Examples

I am having trouble getting the Web Services Tutorial examples to run.
For example, when I compiled the hello1 example, and tried to run it, I got a directory listing. All the directory listing contained was the dukewaving.gif file.
When I tried to run hello2, I got something similar. This time though, there were two jsp files in the listing. By clicking on the first one, I was able to run the application.
Now I can't run the bookstore1 example. I went back a second time, to be sure that I was following the instructions exactly as written. I am gettng an HTTP Status 404 - Servlet BookStoreServlet is not available.
I don't know why this is happening. There were no errors when I ran the Ant targets, and the WAR file did get copied to the webapps directory.
I would be very grateful for any help. I am very new to Java and am finding this very frustrating.
Thank You,
Chrissy

This is what's in my log file. Why is the servlet being marked as unavailable?

Could not run the bookstore1 example from the Java Web Services Tutorial

The bookstore1 servlets example from the Java Web Services Tutorial (issue Aug 1, 2002) was built and deployed successfully by using the deploytool (following the steps described on pages 498ff of the tutorial).
After deploying the application the Tomcat Web Application Manager shows the entry:
/bookstore1:stopped:0:D:\Programme\Java\tomcat\jakarta-tomcat-4.1.8\work\Standalone\localhost\manager\bookstore1.war
when entering the command: http://localhost:8080/manager/list.
After entering the command: http://localhost:8080/manager/start?path=/bookstore1, the (uncomplete) message appears:
FAIL - Application at context path /bookstore1 could not
It should be noted that I was able to build and deploy the application GSApp (chapter 3 of the tutorial) successfully.

Can't find java source to web services tutorial

When I down load the Java Web Services Tutorial zip file, all that is in there are html files. I've read all sorts of references to the source, even a directory structure, but I cannot find the files.
I have gone to:
http://java.sun.com/webservices/downloads/webservicespack.html
And clicked on the Java WebServices Tutorial, v1.5_01 Download.
The java source files to the tutorial are NOT in that zip file.

Hmm, the URL for the tutorial you gave isn't working for me.
I've checked a bit more through the tutorial and JWSDP examples, and they all match for me. I'm looking at JWSDP version 1.5, and the tutorial here:
http://java.sun.com/webservices/docs/1.5/tutorial/doc/index.html
I can't find a 'HelloService' in this tutorial (I also have the tutorial downloaded, grep gave no results). The tutorial refers to, for example, to an example in <JWSDP_HOME>/xmldsig/samples/validate, which I have in my JWSDP. (The page that refers to this example is http://java.sun.com/webservices/docs/1.5/tutorial/doc/XMLDigitalSignatureAPI8.html#wp511406)
If you're really looking at the tutorial version 1.3 (as the URL looks) that could explain it. So, my hunch is a version mismatch, but I could be way off the mark.
