Books and resources teaching J2EE 5 (and creating web services using it)

Hi!
I'm starting a new job next week, developing a J2EE 5 system. I have a solid background in J2SE 1.4 and know most of the new syntactical and semantic stuff in J2SE 5.
What I need is a good book teaching J2SE 5 to someone inexperienced with J2SE in general. There isn't a need for me to study J2SE 1.4 as we won't be using it. Also, we will develop some web services using the platform. As time is of the essence I'd prioritize learning about those within the platform, at first.
I don't need to read the entire book in one week, of course. But I need something to study and also have as a reference by my side when programming.
As the offerings in J2SE 5 books seems quite low, I need some advice from you, more experienced people. What book or web resource do you recommend? Thank you for your time reading this post!
Best Regards,
Kent

Hello Kent!
I have found "Enterprise JavaBeans 3.0" by by Richard Monson-Haefel and Bill Burke really interesting. If you have some knowledge about Java EE in general go for it it's really good one!

Creating Web Services using Java Implementation

Hi,
This is quite a general question on how to create a Web Service using Java Implementation that needs to conform to a client XML schema.
Here are my Version specs,
I am using Jdeveloper 10.1.3.4.0 and deploying onto OAS 10.1.3.
I will be creating a J2ee 1.4 (JAX-RPC) Web Service using Document/Wrapped style.
I have been provided an XML schema from the client which is quite complex.
Using a top-down approach, I can create my WSDL file and import the XML Schema for my type definitions.
The Web service aim is to accept some parameters and return some data from the Oracle Database. The
XML response from the web service must conform to the element, attribute definitions in the provided XML schema.
From a Java implementation approach, what is the best (simplest or quickest) way to retrieve data from the Oracle
tables and map each fields/column to the required XML output (defined in the XML schema).
I'm not too concerned with using Java to retrieve data from the Database, more with how I can map the data returned
to the required output. Can this mapping task be controlled within the Java program?
Thanks in advance.

Creating Web services using JDeveloper for Pl/SQL package having ref cursor

Hi,
I am trying to create web services for PL/SQL package in JDeveloper. When I am trying to create this web service, the functions in the package which is returning referential cursor or record cursor are not visible. When I highlight the function and click "Why Not?", it displays the message "The following types used by the program unit do not have an XML schema mapping and/or serializer Specified: REF CURSOR". Could you please let me know, how I can create this web service?
I am getting similar error when I am trying to create web service for a package with overloaded functions also.
Thanks,

Ok so I played around with this some more. I created the same process in bpel using oracle bpel designer and here are the results.
1. Against 10g database running a synch process data is retutned without error.
2. Against 9i database running an asynch process data is retutned without error.
3. Against 9i database running a synch process data is retutned with error.
I'm definilty missing something.

Create web service using java class

Hi,
I created the web service using java class then i deployed this web service in to the weblogic admin server.when i tested this process it is working fine.
when I tested The generated WSDL to this process in browser(IE). it is not working.
I need to to invoke this webservice from another BPEL but this WSDL is not working.

Hi,
when i created the webservice in jdeveloper by default it is connected to integrated weblogic server and generates this wsdl.
http://localhost:7101/helloApplication-javaexcel-context-root/MyWebService1Soap12HttpPort?WSDL
then I deployed this webservice in to the Adminserver.it gives the following URL.
http://192.168.56.1:7001/extracExcelToCSV-extractExcelToCSV-context-root/ExtractExcelToCSVSoap12HttpPort?wsdl
This URL is not working but when i tested this process it is working fine.
It is giving below error when i try to invoke from jdeveloper

Creating Web Services using Netbeans GUI only

Hi all,
Creating, deploying & testing simple web-services through Netbeans point-n-click interface is quite simple (demo at: http://download.java.net/javaee5/screencasts/hello-simple-glassfish/). The demo shows a very simple service creation scenario, accepting and returning String types only. The service can easily be tested using the GUI option 'Test Web Service', which simply test the service through a simple web page at http://localhost:8080/MyWebApplication/MyWebService?Tester
In a similar manner, I am trying to implement a web service (a little complex one, accepting and returning custom types) using Netbeans GUI only. Versioning information I am using are as follows:
NetBeans IDE 6.1
Sun Java System Application Server 9.1_02 (build b04-fcs)
JAX-WS 2.1.3.1
Roughly speaking, the service's method signature I am using is shown below:
public abstract myclass.X MyService.serviceMethod( myclass.X )
Since it uses a custom type in parameter and return-types, the web-based test doesn't work any more. I wrote a separate client class to invoke the service using client-side stub classes (suppose to be generated by JAX-WS generated classes). The client code looks like as follows:
public class ServiceClient {
     public static void main(String[] args) {
          MyService srv = new MyService ().getMyServicePort();
          X xin= new X();
          X xout= srv.serviceMethod( xin );
          System.out.println( "Result: "+ xout.toString());
Netbeans shows a compiler error on "MyService srv = new MyService ().getMyServicePort();
Is it possible to get it resolved without making use of ant scripts for generating client-side artifacts (stubs etc.)?
Thanks,
irfan

Hello Sandy,
Have you installed the Sun Java System App Server or JWSDP? If so, please make sure that one of the libraries in your Netbeans project contains the jaxrpc-api and jaxrpc-impl jars (which seem to be necessary to run wscompile).
Netbeans ("standalone") doesn't seem to install the jaxrpx libraries and other jars required to compile and run webservices.

Jonatan

Creating web services using WAS 6.40

Hello All,
When I try to create one in my WAS 6.40, I always get stuck @ the entry that prompts for the package. The error messgae that I received is "Test objects cannot be created in foreign namespaces". Can someone advise what could be the problem ? Am I missing something here ? My apologies if the questions is too trivial but I am totally new to all this R/3 / ABAP thingy. Thank you.
from
Kwok Wei

Hi Kwok,
There are two solutions for your problem.
first, if you want to make it transportable then create a
package and asign your object to that package, you'll get
Request Number for package and object assigned.
Secondly you can also save it as Local Object.
To read about web services in details visit <a href="http://help.sap.com/saphelp_nw04/helpdata/en/9b/dad1ae3908ee44a5caf57e10918be9/frameset.htm">this</a> and <a href="http://help.sap.com/saphelp_nw04/helpdata/en/D6/F9BC3D52F39D33E10000000A11405A/frameset.htm">this</a>

Few points
We have created web service using "oracle.j2ee.ws.StatelessJavaRpcWebService" servlet
Thanks in advance.

Hi,
It might be that the .net service which you have is not WS-I compliant. Can you first run WS-I Analyzer on the wsdl to see it the test passes.

Creating web service for bapi and consume in portal.

Hi ,
I am new to Web Services. This is my requirement I need to publish the functionality of bapi as a web service and consume the web service from portal side.
I have followed these steps to create web service.In transaction se80 i have created service definiton and a wsdl file is generated.
When i am exporting that WSDL file and creating a model in a webdynpro project. I am getting the following error. I dont know how to proceed further.Error while loading WSDL.Check error log for more details.
Whether the proxies need to be generated?What is the purpose of it? Where the proxies need to be generated?
Is Process integration needed to use web services?
Kindly guide me how to proceed.
Best Wishes
Idhaya R

the proxy is the object that make possible to use the service; even if service and consumer are on the same host, you need a proxy to use it.

Creating Web Service in Eclipse with Axis and Tomcat

Hi I'm quite new to web services. But I got a compiled class that i want to create a web service of. Since this class is compiled and lies in a package I can't just use the WTP and create a Buttom Up Web Service. So I created av wrapper class to this class to see if that would solve the problem, but i still get error messages that it's not JAX-RPC compliant. I've decompiled the class file I want to create a web service of and made a wrapper class with an interface around this class.
package org.ejbca.core.protocol.ocsp;
import org.bouncycastle.ocsp.*;
public class OCSPResponse
public OCSPResponse()
resp = null;
fnr = null;
httpReturnCode = 200;
errCode = 0;
public OCSPResponse(OCSPResp ocspresp)
resp = null;
fnr = null;
httpReturnCode = 200;
errCode = 0;
resp = ocspresp;
public int getHttpReturnCode()
return httpReturnCode;
public void setHttpReturnCode(int code)
httpReturnCode = code;
public int getErrorCode()
return errCode;
public void setErrorCode(int code)
errCode = code;
public String getFnr()
return fnr;
public void setFnr(String fnr)
this.fnr = fnr;
public OCSPResp getResp()
return resp;
public void setResp(OCSPResp resp)
this.resp = resp;
public int getStatus()
Something
private OCSPResp resp;
private String fnr;
private int httpReturnCode;
private int errCode;
OCSPResp is an object from boncycastle, as i found out one of the problems is that OCSPResponse is a non Non-Built-In Data Type and don't just contain bulit-in datatypes.
So can anybody give me a detaild input on how to solve this problem, including some hints on how to create a wrapper incase I've done something wrong.
