Webservices: jwsc is unable to compile wsdlc-generated classes

Hello,
I'm trying to generate JAXWS web service classes using WebLogic 10.0 MP1 wsdlc and jwsc Ant tasks, following the steps described in [Creating a Web Service from a WSDL File|http://edocs.bea.com/wls/docs100/webserv/use_cases.html#wp220705].
I'm using the WSRP WSDL which I have in my local system and which is also available at [http://docs.oasis-open.org/wsrp/v2/wsrp-service.wsdl]. The only change I made is to remove all the references to "v1" specification of WSRP in there.
It seems that wsdlc can only work with a single service and single port so I'm currently trying to generate just the classes for WSRP_v2_Markup_Service port.
Here are my ant tasks:
<wsdlc type="JAXWS" srcWsdl="${wsdl.path}" srcPortName="WSRP_v2_Markup_Service" destJwsDir="${target.jws.dir}" destImplDir="${target.impl.dir}" />
<jwsc srcdir="${target.impl.dir}" destdir="target/wls-wsrp-ws.ear">
<jws type="JAXWS" file="oasis/names/tc/wsrp/v2/wsdl/WSRPV2ServiceImpl.java" compiledWsdl="target/compiledWsdl/wsrp-2_0-service_wsdl.jar">
<WLHttpTransport contextPath="${contextPath}" serviceUri="WSRP_v2_Markup_Service" />
</jws>
"wsdlc" part succeeds but jwsc part fails with the following error message:
[jwsc] C:\DOCUME~1\zachcial\LOCALS~1\Temp\_970x54\oasis\names\tc\wsrp\v2\wsdl\WSRPV2MarkupPortType.java 263:28

[jwsc] [ERROR] - javax.jws.WebService.endpointInterface oasis.names.tc.wsrp.v2.wsdl.WSRPV2MarkupPortType is invalid.
Looking at the interface class and line I find both WebMethod and WebResult annotations for the methods above, e.g.:
*@WebMethod(action = "urn:oasis:names:tc:wsrp:v2:releaseSessions")*
*@WebResult(name = "extensions", targetNamespace = "urn:oasis:names:tc:wsrp:v2:types")*
@RequestWrapper(localName = "releaseSessions", targetNamespace = "urn:oasis:names:tc:wsrp:v2:types", className = "oasis.names.tc.wsrp.v2.types.ReleaseSessions")
@ResponseWrapper(localName = "releaseSessionsResponse", targetNamespace = "urn:oasis:names:tc:wsrp:v2:types", className = "oasis.names.tc.wsrp.v2.types.ReturnAny")
public List<Extension> releaseSessions(
@WebParam(name = "registrationContext", targetNamespace = "urn:oasis:names:tc:wsrp:v2:types")
RegistrationContext registrationContext,
@WebParam(name = "sessionIDs", targetNamespace = "urn:oasis:names:tc:wsrp:v2:types")
List<String> sessionIDs,
@WebParam(name = "userContext", targetNamespace = "urn:oasis:names:tc:wsrp:v2:types")
UserContext userContext)
throws AccessDenied, InvalidRegistration, MissingParameters, ModifyRegistrationRequired, OperationFailed, OperationNotSupported, ResourceSuspended
I found the following post of somebody having a similar problem: [http://forums.bea.com/thread.jspa?threadID=600014665]. Unfortunately for me both interface and implementation method declarations look exactly the same except the @Web... annotations not present in the implementation class.
Can you think about anything I'm doing wrong?
Thanks in advance for any help.

I figured that out.
It turns out that the order of exceptions in the interface class and in the generated implementation class are not the same. Even though this is fine from the Java perspective, jwsc gets confused by this. Putting the exceptions in the method signatures of the implementation class in the same order as in the interface fixes this issue.
Now, I hit another problem:
jwsc error: Response wrapper bean names must be unique and must not clash with other generated classes. Class: oasis.names.tc.wsrp.v2.wsdl.WSRPV2MarkupPortType method initCookie(oasis.names.tc.wsrp.v2.types.RegistrationContext,oasis.names.tc.wsrp.v2.types.UserContext)
Let's see how long will it take to find a fix for this one ...

Unable to compile ( not creating class file ) java file

Hi
I am unable to compile java file in eclipse. I am using Tomcat 5.0 and eclipse 3.0. I am able to compile the file from command prompt. I installed eclipse and did all settings including Build path ( WEB-INF\classes). But I donot see any class file getting created.

Are you seeing errors when eclipse compiles you classes? Have you tried to build your project using; Project -> Build All? If you have and it looks like no errors are generated you may need to change your perspective. Try changing to the resource perspective to see the built class files; Window -> Open Perspective -> Other -> Resource. By default built class files end up in the bin directory of the project. i usually change my built classes directory to classes, just makes more sense to me.

Do java programms after giving compilation error generates .class file?

Do java programms after giving compilation error generates the .class file?
Do any outer class may have the private as access modifier?
If someone asks you that -do any program in java after giving a compilation error gives the .class file -do any class except(inner class)
be defined as private or static or protected or abc or xxx Now type the
following program
private class test
public static void main(String s[])
System.out.println("Hello!How are You!!");
-Compile it.... You must have
received this error test.java:1:The type type can't be private. Package members are always accessible within the current package. private class
test ^ 1 error
Here please notify that compiler has given the
error not the warning therfore .class file should not be created but now type
>dir *.class
___________ and you will see that the
test.class file existing in the directory nevertheless this .class file
is executable. if you will type __________________ >java test
it will
wish you Hello! and suerly asks you that How are You!! ________________!
You can test it with the following as acces modifiers and the progrm will run Ofcourse it will give you compilation error.
protected
xxx
abc
xyz
private
Do you have any justification?

Hmm,
I've been working with different versions of jdk since, if I'm not mistaken, jdk1.0.6 and never was able to get *.class with compilation errors. It was true for Windows*, Linux, and Solaris*.
About the 'private'/'protected' modifier for the type (class) - it makes perfect sence not to allow it there: why would anyone want to create a type if no one can access it? There should be a reason for restricting your types - let's say, any inner class can be private/protected.
For ex., you shouldn't have compile problems with this:
class Test
public static void main(String s[])
System.out.println("Hello!How are You!!");
private class ToTest{}
Sorry, but I don't really know where you can read up on that.

Ws compile client generates wrong method signature

Hi,
the wscompile - option client - always generates the wrong method signature in the class AdresseIF_Stub:
--> public de.skkoeln.webservice.web.Adresse_Type[]
I need the signature public de.skkoeln.webservice.web.Adresse[] due to I can't compile the generated classes. This is the signature of the AdresseIF interface.
What is my fault ?
Oliver
Adresse ist the JavaClass which I expect to get as return value. The webservice was successfully installed

Oliver, is it only wrong in the stub? Does all of the generated code compile? If it all compiles then there is no error. The reason the _Type was added is because they are other WSDL names that have the same name. Please read section 4.3.12 of the JAXRPC spec for more detail.

How to compile the Java classes generated in JAXB

I am using Windows 2000 Operating System. I found a xjc

Error compiling the BPEL classes while configuring custom approval process

Hi,
I get the below error, but unable to fix this. Any one who did face this issue please share your thoughts to overcome this.
Error(45,34): Failed to compile bpel generated classes.
failure to compile the generated BPEL classes for BPEL process "ApprovalProcess" of composite "default/SelfRegistrationApproval!1.0"
The class path setting is incorrect.
Ensure that the class path is set correctly. If this happens on the server side, verify that the custom classes or jars which this BPEL process is depending on are deployed correctly. Also verify that the run time is using the same release/version.
Thanks,
Bhaskar

You need to keep all the custom jars at three places :
1) Soa ext , and make sao extension jar by running ant
2) Bpel classpath
3) in your project as an external referrence

}I read in one blog (actually - the only page which was returned by yahoo - so - this should be very rare error!!!) to try to use Sun server's verifier.bat - and - it reported 0 errors and 0 warning. Build was succesfull as well and also - deployment was without errors - but - above mentioned error appeared during the automatic compilation of jsp pages/servlet when newly deployed jsps are first accessed from remote browser.
So - is it possible, please, to receive some advice - what to do further? I feel that my invoice.jsp page can be with errors, - however - the original welcomeJSF.jsp should be working without errors even the erronwous JFS jsp page is added to web application.
Thans for any adice or hint in advance!!!

OK - I have made 'clean and build main project' from NB menu and the deployed the resulting *.war and the error messages have disappeared... So - it seems to be bug...

When i ran the xjc , it generated 3 .java files
AddCtq.java , Ctq.java and VariableData.java
But i am unable to compile any of the above files...
The Error i am getting is
VariableData.java:710: Undefined variable or class name: AddCtq
return AddCtq.newDispatcher();
^
1 error
If i try to compile AddCtq.java , the Error i am getting is
AddCtq.java:4: Class com.geindustrial.sqms.Ctq not found in import.
import com.geindustrial.sqms.Ctq;
^
AddCtq.java:169: Class com.geindustrial.sqms.Ctq not found.
if (!(ob instanceof Ctq)) {
^
AddCtq.java:170: Class com.geindustrial.sqms.Ctq not found.
throw new InvalidContentObjectException(ob, (Ctq.class));
^
3 errors
And when i try to compile Ctq.java , i am getting the following Error:
Ctq.java:4: Class com.geindustrial.sqms.VariableData not found in import.
import com.geindustrial.sqms.VariableData;
^
1 error
How to solve this problem..Pls advise...
Thanks
Sateesh

I suspect you are trying to compile the files one by one. You may also be trying to compile them disregarding the package structure.
From your post, I gather these files are in the package: com.geindustrial.sqms
Therefore, if they are not so already, put them under a directory structure:
com/geindustrial/sqms
and then compile with:
javac com/geindustrial/sqms/AddCtq.java com/geindustrial/sqms/Ctq.java com/geindustrial/sqms/VariableData.java
(The above is all on one line.)

Unable to compile class for JSP

Please can anyone help me to solve this.
Actually,this is the condition.
In my db,there is a table called UserPassword, which has 4
fields(empNo,UserName,password,level). Now I want to do these things:
When the user submits the data to create a new account via HTML form, it submits the data to the file called CreateAcc.jsp. In this file it perform some logic,here are they.
1)To check the empNo,if it is already exist in the DB,
     if empNo =exist then display error.(record already exist)
     if empNo =notexist then do task 2).
2)check the UserName,if it is already exist in the db,
     if UserName=exist then display error.(because it's a primary key)
     if UserName=notexist then do task 3).
3)Create a new user account and save it to the db.
To do these tasks,I never create a new objects for the tasks 1) and 2).
only for task 3)create an object.
Is it the right way?
Here is the file CreateAcc.jsp
<%@ page language="java" %>
<%@ page import="core.UserAccManager" %>
<%@ page import="data.UserPassword" %>
<jsp:useBean id="UserAccManager" class="core.UserAccManager" scope="session"/>
<jsp:setProperty name="UserAccManager" property="*"/>
<jsp:useBean id="UserPassword" class="data.UserPassword" scope="session"/>
<jsp:setProperty name="UserPassword" property="*"/>
<%
String nextPage ="MainForm.jsp";
if(UserPassword.verifyEmpno()){
     if(UserPassword.verifyUsername()){
          if(UserPassword.createAcc()) nextPage ="MsgAcc.jsp";
      }else{
           nextPage="UserNameExist.jsp";
      else{
          nextPage="UserAccError.jsp";
%>
<jsp:forward page="<%=nextPage%>"/>The directory structure:
UserPassword.java- F:/Project/core/data/UserPassword.java
UserAccManager.java - F:/Project/core/UserAccManager.java
Now both are compiling.I put the class files into the TOMCAT,as follows.
UserAccManager.class - webapps/mySystemName/WEB-INF/classes/core/
UserPassword.class - webapps/mySystemName/WEB-INF/classes/core/data/

Are there any mistakes? If so tell me where is it and how to change them.Please help.

I try it that way, but it don't compile.
Error:core\data\UserPassword.java:package javax.servlet does not exist
import javax.servlet.*;
core\data\UserPassword.java:package javax.servlet.http does not exist
import javax.servlet.http.*;
So,I comment them only in the UserPassword.java file,and compile it again.
Then it compile well.I goto the directory to get the .class files.
But there is only UserPassword.class inside the data folder. There is not
UserAccManager.class in the core folder.
Then I try this way,I put my 2 java files in to a new folder,
F:\SystemName\com
When I try it that way, but it don't compile.
javac -classpath . -d . com\*.javaError:com\UserPassword.java:package javax.servlet does not exist
import javax.servlet.*;
com\UserPassword.java:package javax.servlet.http does not exist
import javax.servlet.http.*;
So,I comment them only in the UserPassword.java file,and compile it again.
Now both are compiling well.There was 2 class files.
I put them in to the WEB-INF/classes/com directory.
Start the server.But it gave errors:

ER unable to compile using javac with java 1.3.1 library (JDEV 10.1.3.0.4)

Hi !
When I try to compile in JDev with javac and the java 1.3.1 library, I get the following error :
Error: javac: invalid flag: -source
The command line generated by JDev looks like :
C:\jdk1.3.1_03\bin\javac.exe -J-mx512m -verbose -deprecation -source 1.3 -target 1.3 -encoding Cp1252 -g -classpath [...] -sourcepath [...] -d [...] @C:\DOCUME~1\user\LOCALS~1\Temp\javac54193.tmp
It seems that -source and -target flags do not exist in this version of javac.
But it does not seem possible to remove these flags generated by JDev, so I'm unable to compile with javac 1.3.1 and JDev.
So i'm looking for :
- A workaround to prevent JDev from adding the -source and -target flags.
- A future release of JDev where you could disable these flags, or, much better, where JDev automatically disables these flags when it detects a 1.3.1 library (there may be other incompatible flags I did not mention).
Thank you for your answers :)

Hi,
when you open the project properties and choose the compiler option to tht the compiler to "javac" and then the "source" and "target" to 1.3, wouldn't this compile it for Java 3? I don't think that it is necesary to use JDK 1.3 for compiling the sources
Cross-Compilation Options
By default, classes are compiled against the bootstrap and extension classes of the platform that javac shipped with. But javac also supports cross-compiling, where classes are compiled against a bootstrap and extension classes of a different Java platform implementation. It is important to use -bootclasspath and -extdirs when cross-compiling; see Cross-Compilation Example below.
-target version
Generate class files that will work on VMs with the specified version. The default is to generate class files to be compatible with the 1.2 VM in the Java 2 SDK. The versions supported by javac in the Java 2 SDK are:
1.1
Ensure that generated class files will be compatible with 1.1 and VMs in the Java 2 SDK.
1.2
Generate class files that will run on VMs in the Java 2 SDK, v 1.2 and later, but will not run on 1.1 VMs. This is the default.
1.3
Generate class files that will run on VMs in the Java 2 SDK, v 1.3 and later, but will not run on 1.1 or 1.2 VMs.
1.4
Generate class files that are compatible only with 1.4 VMs.

Unable to compile class for JSP. apache-tomcat-6. What could be wrong?

Hello, I am new to JSP and I am trying a very basic jsp and class file on Windows XP. I get the Unable to compile class for JSP.
Steps that I have done:
javac ch06_01.java , placed the ch06_01.class under
C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes
Then grabbed the ch06_02.jsp and placed it under
C:\Apps\apache-tomcat-6.0.16\webapps\ch06\
When I run it (by placing this into Explorer or Firefox URL
http://localhost:8080/ch06/ch06_02.jsp) I get the error further
below. Things I have done and made sure they are in place are:
set up JAVA_HOME to C:\Apps\jdk1.6.0_06
Using CATALINA_BASE: C:\Apps\apache-tomcat-6.0.16
Using CATALINA_HOME: C:\Apps\apache-tomcat-6.0.16
Using CATALINA_TMPDIR: C:\Apps\apache-tomcat-6.0.16\temp
Using JRE_HOME: C:\Apps\jre1.6.0_06
I did a google on the error and I found people saying to place the
tools.jar from the jsk into the lib directory under CATALINA_HOME. But
the examples still don't work. What step could I be missing? Your help is greatly
appreciated.
This is the simple jsp file:
<%@ page import="ch06_01" %>
<HTML>
<HEAD>
<TITLE>Using a JavaBean</TITLE>
</HEAD>
<BODY>
<H1>Using a JavaBean</H1>
<% ch06_01 messager = new ch06_01(); %>
The message is: <%= messager.msg() %>
</BODY>
</HTML>
this is the simple ch6_01 java file:
public class ch06_01
public ch06_01()
public String msg()
return "Hello from JSP!";

I just updated the directories of the variables to reflect the current status of my system.

What is wrong is that you are using an "old" jsp tutorial :-)
Since Java 1.4, JSPs have been unable to access classes in the "default" package.
What you need to do:
Put the java class ch06_01 in a package.
Steps to do this
- Edit ch06_01 and add the following to the very top of the file (without the quotes): "package mypackage;"
- create a folder "mypackage"
- move ch06_01.java into that folder
- compile that class (now in the mypackage package)
- place ch06_01.class under C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes\mypackage
In your jsp:
<%@ page import="mypackage.ch06_01" %>
I would suggest using a more up-to-date tutorial that uses JSTL.
Take a look at this [Apache Tomcat tutorial|http://www.coreservlets.com/Apache-Tomcat-Tutorial/index.html]

Unable to compile class for JSP--- help me plz!!!!!

hi friends;
Pease suggest me where i am wrong, i think javabean is not instantiated in jsp file.may be it is related to the classpath of javabean. i have not set any variable for javabean classpath. and i put javabean class file in
TOMCAT_HOME/webapps/test3/WEB-INF/UseDta.class
and all the jsp and html in /test3. my jsp an javabeans are--
1. GetName.html
<HTML>
<BODY>
<FORM METHOD=POST ACTION="SaveName.jsp">
What's your name? <INPUT TYPE=TEXT NAME=username SIZE=20><BR>
What's your e-mail address? <INPUT TYPE=TEXT NAME=email SIZE=20><BR>
What's your age? <INPUT TYPE=TEXT NAME=age SIZE=4>
<P><INPUT TYPE=SUBMIT>
</FORM>
</BODY>
</HTML>
2. SaveName.jsp
<jsp:useBean id="user" class="UserData" scope="session">
<jsp:setProperty name="user" property="*"/>
</jsp:useBean>
<HTML>
<BODY>
Continue
</BODY>
</HTML>
3. UserData.java
public class UserData {
String username;
String email;
int age;
public UserData(){}
public void setUsername( String value )
username = value;
public void setEmail( String value )
email = value;
public void setAge( int value )
age = value;
public String getUsername() { return username; }
public String getEmail() { return email; }
public int getAge() { return age; }
4. NextPage.jsp
<jsp:useBean id="user" class="UserData" scope="session"/>

if you want to know how to declare a package for your classes
Follow the steps to make your application work
Make this as the first statement in your DbConnect1 class
package DbConnect1;
Compile the class and place the DbConnect1.class file into
Tomcat/webapps/<yourapplication>\WEB-INF\classes\package\ directory
for eg : if your package name is test then place the class files under
Tomcat/webapps/<yourapplication>\WEB-INF\classes\test directory
This is where Tomcat looks for class files
If you have any doubts regarding directory dtructure to be followed in Tomcat please refer to some of the example packages under Root directory
In your JSP say
page import = packageName. DbConnect1
-Hope this helps
