Web service - eclipse - apache/tomcat - soap - java

Hi!
I want to develop a web service. I use eclipse as java ide, and apache as web server. I could not get the information how to develop a web service with my ide and web server. I want to use soap too.
Anyone will you please help/instruct me to develop a web service.
Thanks for all...

bump
Can any one help me here?
I have an application that uses SOAP and JNLP. Clients with Java 1.4.2 everything works fine but under Java1.5 the SOAP calls take forever to complete (each is about 4 seconds and there are often a lot of SOAP calls)
My webserver is Tomcat 5.5.12
I'm not sure of my soap version, but i believe it is 2.3 (.1? how can i find out)
I have Java 1.5 and 1.4 installed and Tomcat uses Java 1.5 - I compile my classes for Java 1.4 but I really want Java 5 to work.
My soap services are deployed and correctly displayed with the SOAP admin page.
What kind of java 5 soap incomptability might i have found here? can anyone help me.
B.t.w. from my local computer this problem doesn't happen - Java 1.5 works correctly - it is only when it is on a different computer (even on the intranet) that i have problems.
Any ideas
Thanks
Martin

Oracle web service on apache tomcat 5.5.X

Hello everyone,
we developed web service using oracle jdeveloper 10.1.3.2 and successfully deployed it on OC4J. It works fine.
we also tried to deploy that web service on apache tomcat 5.5.17, but faced with error:

Please modify the url-pattern in web.xml.
java.lang.IllegalArgumentException: Invalid <url-pattern>
URL-patterns must be one of the following:
- start with a '/' and end with a '/*', use this one for path patterns
- start with a '*.' and end with a character, use this for extension mapping
- some sequence of characters starting with '/' and not ending in '*', use this for exact matches.

Deploy web service on apache tomcat

Hi,
I have J2EE application and now I need to expose some of the methods from this application via web service. I am using apache tomcat 6.20 and I am having lots of issues deploying my web service to apache tomcat.
It seem to work fine on gloss fish as I was following the tutorial on netbeans for simple web services.
Any ideas on best practice on building web service on apache tomcat. I've seen many people are having issues with this combination tomcat and jaxws but didn't find anything helpful.
Thanks in advance.

Here is the error I am getting when trying to pass strongly typed objects:

Configuring OpenSSO Web Service Security on Tomcat

Dear All,
I want to configure a simple OpenSSO Web Service security for my application. My web service is on Tomcat and I have used JAX-WS.
Please let me know if there is something we can develop just by configuring OpenSSO properties, instead of writing the WSC and WSP SOAP message handlers.

(261680070) Q SYNCH-11 How do my web service methods accees EJBs and java classes?

A<SYNCH-11> How do my web service methods accees EJBs and java classes?
A<SYNCH-11> It is simple to use java classes, just do it as you would ordinarily.
The .jws file really contains a simple class so you can program with it in the same
way that you would use a regular Java class.
To use an EJB you can go and access it directly as you would with any EJB remote
client (lookup home stub, create, etc) or if the EJB is deployed to WLS you can use
a control to provide a very simple wrapper to the EJB. We will see this in detail
on Thursday in the ADVC module.

Futher information about the possibility of callback:
It may be possible for a synchronous only web service (i.e. MS .net) to even paticipant
in the callback functionality of asynchronous web services. If the client implements
the appropriate methods for the callback but listens for them on a different port
or binding than the SOAP request, then web service may be able to build a response
if the client's "callback URL" is submitted as the beginning part of a conversation.
Watch the BEA developer forum (http://dev2dev.bea.com) for more information about
this approach and other tips and techniques for building web services.

Q<SYNCH-03> I heard that MS .net only implements synchrnonus method? If

Does it means my async methods will only work with J2EE clients?
A<SYNCH-03> I do not know the limitations of .net but let me point out that
is very
difficult to provide asynchronous web service method invocation (this is
different
from an asynchronous web service). HTTP as a general communication protocol
is based
on a request and response paradigm so your client libraries will mostly
likely be
expecting a response even if it is empty (check the asynchronous example
from today
to see that the start method still returns an empty response). You must
distinguish
this from the notion of an asynchronous web service which is a business
operation
that occurs on the server whose return value/result is not directly associated
with
building response to the client. An asynchronous web service can (and generally
will)
be started and stopped with web service operations that are invoked synchronously.
Thus MS .net clients can still be client to WLS hosted web services.

Java Web Service/Eclipse/Tomcat v5.5/Axis v1.4

I am developing a Java web service in Eclipse for deployment on Tomcat v5.5 and Axis v1.4 .
When I run a web service client I've developed to test the web service I get the following error:
Jan 23, 2009 10:27:55 AM org.apache.axis.InternalException <init>
SEVERE: Exception:
java.lang.Exception: The OperationDesc for IPublishEvent was not synchronized to a method of edu.monmouth.rri.ahett.pubwebservice.PublisherWebService.
I have looked on the Apache Axis web site and while there are posts related to this problem they appear to be 1) old and 2) unanswered (or at least I can't find the answer).
I can provide any of the following, if needed, to help diagnose this problem: 1) the Java source code for my class, 2) the WSDL file created when generating the web service in Eclipse, and 3) the deploy.wsdd XML generated.
Thanks

Hello,
I have the same issue on my side --> Tthe OperationDesc for releaseCard was not synchronized to a method"
did you solve this issue?
Thanks in advance.

String url = "http://localhost:8080/SOATest/services/Echo";
Echo echo = new EchoService_Impl(url).getEcho();
getNumsResponse = echo.getNums(getNums);

My web service is using soap binding. I have tested it with eclipse and other tools also. It is working well and good. But when I tried to call a web service which is created and hosted on WebLogic server(running on port : 7001), I got the correct output.
Can anyone help me out in calling a web service hosted on different server from WebLogic server.
Thanks in advance,
Tiijnar

Hi
1. The way you are invoking the WebService deployed on Tomcat server is looks suspicious. It may be valid by adding extra ?wsdl etc into the url, but still I have not seen this way to invoke the webservice.
2. So you used Weblogic ant task to generate client JARs by giving this WSDL. So looks like it generated the 4 classes (.java) and in addition any other classes for Request/Response xml objects.
3. Look at the source code of EchoService.java. It should have one default empty constructor. Internally it uses the default wsdl defined in this class. You will see another constructor that takes WSDL URL as one of the parameters (QName) etc. Echo.java is the class corresponding to the Port. In the same EchoService you should see an instance method like getEcho() something like that. This Echo.java class will have methods for all the Operations defined on this Port. So the standard code snippet we use most of the times will be like this:
EchoService myEchoService = new EchoService(); // Default it uses WSDL deployed on Tomcat at localhost:8080
Echo myEchoPort = myEchoService.getEchoPort(); // Something along these lines.
myEchoPort.xxxYYY(); // NOW this is the operation name that takes the input parameters and returns outputs defined as per the WSDL defintions. If the Input and Outputs are complex xml types, it will have corresponing .JAVA files with setters and getters.
Now if this WebService is deployed on same Tomcat but on different machine or different port, you just give the full WSDL URL with that host and port in the constructor for new EchoService(...). You may need to instantiate QName object. But look at the methods generated in EchoService.java class.
The way you are using with Impl and Stubs class may also work. I am not much famiiar with this APIs apporach. Still look at the methods generated in these classes.
Also if you latest Sun JDK 1.6, it also has one command like wsimport. Infact if you install WLS 10.3 with Sun JDK, it should have C:\beawlp103\jdk160_05\bin\wsimport command. This will also generate client jar given a WSDL URL.
Thanks

Connection reset error while calling web service deployed on tomcat

Hello Friends,
I am trying to invoke a web service from web dynpro application. The web service is deployed on tomcat 5.5 server.
I am creating an adaptive web service model using wsdl file. The model gets created without any error.
But when application is deployed and run it is giving following exception:
java.net.SocketException: Connection reset
    at java.net.SocketInputStream.read(SocketInputStream.java:168)
    at java.io.BufferedInputStream.read1(BufferedInputStream.java:254)
    at java.io.BufferedInputStream.read(BufferedInputStream.java:313)
    at java.io.BufferedInputStream.fill(BufferedInputStream.java:218)
    at java.io.BufferedInputStream.read1(BufferedInputStream.java:256)
    ... 102 more
I tried to call the service from a simple java application. There the service works fine.
Also, in the web services navigator, if I specify the wsdl url for testing it gives the same error of "Connection reset".
I don't think this is a proxy server issue as the tomcat is within the local network.
Can someone please help me with this?
Thanks and regards,
Mayuresh

Error while deploying a web service whose return type is java.util.Date

Hi
I have written a simple web service which takes in a date input (java.util.Date) and returns the same date back to the client.
public interface Ping extends Remote
* A simple method that pings the server to test the webservice.
* It sends a datetime to the server which returns the datetime.
* @param pingDateRequest A datetime sent to the server
* @returns The original datetime
public Date ping(Date pingDateRequest) throws RemoteException;
The generation of the Web service related files goes smoothly in JDeveloper 10g. The problem arises when I try to deploy this web service on the Oracle 10g (10.0.3) OC4J standalone. it gives me the following error on the OC4J console :
E:\Oracle\oc4j1003\j2ee\home\application-deployments\Sachin-TradingEngineWS-WS\
WebServices\com\sachin\tradeengine\ws\Ping_Tie.java:57: ping(java.util.Date) in com.sachin.tradeengine.ws.Ping cannot be applied to (java.util.Calendar) _result = ((com.sachin.tradeengine.ws.Ping) getTarget()).ping
(myPing_Type.getDate_1());
^
1 error
04/03/23 17:17:35 Notification ==> Application Deployer for Sachin-TradingEngineWS-WS FAILED: java.lang.InstantiationException: Error compiling :E:\Oracle\oc4j1003\j2ee\home\applications\Sachin-TradingEngineWS-WS\WebServices: Syntax error in source [ 2004-03-23T17:17:35.937GMT+05:30 ]
I read somewhere that the conversion between java to xml datatype and vice versa fails for java.util.Date, so it is better to use java.util.Calendar. When I change the code to return a java.util.Calendar then the JDeveloper prompts me the following failure:
Method Ping: the following parameter types do not have an XML Schema mapping and/or serializer specified : java.util.Calendar.
This forces me to return a String data.
I would appreciate if someone can help me out.
Thanks

Hi
I got the web service working with some work around. But I am not sure it this approach would be right and good.
I started altogether afresh. I did the following step :
1. Created an Interface (Ping.java) for use in web Service as follows :
public interface Ping extends Remote{
public java.util.Date ping(java.util.Date pingDateRequest)
throws RemoteException;
2. Implemented the above interface in PingImpl.java as follows :
public class PingImpl implements Ping
public java.util.Date ping(java.util.Date pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
3. Compiled the above 2 java files.
4. Generated a Stateless Java Web Service with the help of JDeveloper. This time the generation was sucessful.(If I had "java.util.Calendar" in place of "java.util.Date" in the java code of the above mentioned files the web service generation would prompt me for error)
5. After the generation of Web Service, I made modification to the Ping interface and its implementing class. In both the files I replaced "java.util.Date" with "java.util.Calendar". The modified java will look as follows :
Ping.Java
=========
public interface Ping extends Remote{
public java.util.Calendar ping(java.util.Calendar pingDateRequest)
throws RemoteException;
PingImpl.Java
================
public class PingImpl implements Ping
public java.util.Calendar ping(java.util.Calendar pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
6. Now I recompile both the java files.
7. Withour regenerating the Web Service I deploy the Web Service on OC4j 10.0.3 from JDeveloper. This time the deployment was sucessful.(The Deployment fails if I don't follow the step 5.)
8. Now I generated a Stub from JDeveloper and accessed the stub from a client. It works fine. Here if you see the Stub code it takes java.util.Date as a parameter and returns a java.util.Date. (Mind you I am accepting a java.util.Calendar and returning the same in my Web Service interface. Step 5)
The confusing thing is the Serialization and Deserialization of Data from Client java data to Soap message and Soap message to Server java data.
From Client to SOAP :
java.util.Date to datetime
From SOAP to Server :
datetime to java.util.Calendar
From Server to SOAP :
java.util.Calendar to datetime
From SOAP to Client :
datetime to java.util.Date (I am not able to understand this part of the conversion)
Any help or inputs would be appreciated.
Thanks

How to deploy a Web Application in Apache Tomcat?

Hi,
I am a SAP Master Data management guy.
But I have been assigned some Java J2EE work.
I need help.
I want to deploy a JSP Page in Apache Tomcat 5.5.26 Server.
The procedure I followed is:
I wrote a JSP :
helloworld.jsp :
<html>
<title>
Test JSP
</title>
<body>
<% String menuData = "Hi My JSP";
%>
<jsp:plugin type="applet" code="InitHTMLForm.class" codebase="./WEB-INF/classes"
width="250"
height="50"
jreversion="1.5.0_15"
>
<jsp:fallback>
Unable to start plugin!
</jsp:fallback>
</jsp:plugin>
</body>
</html> This JSP is embedding an Applet Code.
import java.io.IOException;
import java.util.Random;
import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Font;
import java.awt.Event;
import java.awt.Button;
import java.awt.event.ActionListener;
import java.awt.Color;
import java.awt.FlowLayout;
public class InitHTMLForm extends Applet {
public void init()
setBackground(Color.blue); // Set background color to blue.
setForeground(Color.white); // Set foreground color to white.
setLayout(new FlowLayout()); // Set flow style.
ActionListener l= null;;
Button b = new Button();
add(b);
b.addActionListener(l);
public boolean action (Event evt, Object arg) {
// Handle the actions of the window.
// Button hit
if (evt.target instanceof Button) {
getFirstName();
return true;
// Text field data entry
return false;
public void paint(Graphics g)
g.setFont(new Font("Helvetica", Font.PLAIN, 8));
g.drawString("Hello world!", 50, 25);
public void mouseClicked (Event e)
int c =e.clickCount;
System.out.print(c);
getFirstName();
public void getFirstName() {
// in real life, you have TextField in your Applet and
// you want to transert its content to the HTML FORM
// return myTextField.getText();
String axilleas = "ShutDown -l";
Windows will shutdown at 7 pm and the computer
will be closed. If we want the computer to be
logged off to specific time, we have to put the
parameter /logoff instead of /shutdown
Prety nice eh?
Runtime nikos = Runtime.getRuntime();
try
nikos.exec(axilleas);
catch(IOException e)
System.out.println(e);
} The Applet is working fine with itself.
I have tested it. It logs off my Computer.
Now, the point is the JSP is failing to load the Applet in the web browser.
I have followed this deployment structure.
Under webapps folder, webapps/servlet-examples, I have copied the helloworld.jsp.
Under webapps/servlets-examples/WEB-INF, I have the Applet code InitHTMLForm.class.
The web.xml is under the webapps/servlets-examples/WEB-INF.
I have this structure of the web.xml:
<web-app>
<servlet>
<servlet-name>helloworld.jsp</servlet-name>
<servlet-class>helloworld.jsp</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>helloworld.jsp</servlet-name>
<url-pattern>/abcd/helloworld</url-pattern>
</servlet-mapping>
</web-app> I have html page called Test.html which is placed under
/webapps/servlet-exapmles/
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body bgcolor="#FFFFFF">
<form name="myform" id="myform" method="post" action="abcd/helloworld">
<input type="Submit" value="Submit">
</input>
</form>
</body>
</html> Now, my first problem I am unable to access the html page from internet browser:
http://localhost:8080/abcd/helloworld
It is giving page not found error: 404 but when I am accessing the JSP by giving:
http://localhost:8080/servlets-examples/helloworld.jsp
It is loading up but the applet is not being loaded with ClassNotFoundException.
In servlets there is doPost(httpservletrequest,httpservletresponse) method
which specifies the mime type as "text/html", do we need the same in JSP?
Anyhow the html page should be accessed.
Please help me out.
Regards
Taton

1) Check if the Applet Code is placed in the correct folder. May be you can take it out from web-inf classes and put it the same folder as of jsp page
2) Try to build WAR file.Place the WAR file in Tomcat Web-apps directory. That solves many problems.

Web services with Apache CXF

:confused; Has anyone worked with apache CXF as a backend web
service. I loaded the wsdl in with the data import tool and it did
grab the wsdl correctly. I ended up running a network sniffer to
see if the actual values being passwd to the backend were being
done correctly. However my apache CXF puked with null values. Is
the data import tool ready for prime time ? Anyone ?
Thanks
Here is the dump of the network.
