JAXB unable to compile generated package

following the tutorial I ran xjc.sh on my xsd file generating a package with a -p option.
when I ran javac user/*.java /usr/impl/*.java I received 100 error message all basicly complaining about missing classes
ex:
user/impl/UserDataImpl.java:13: package com.sun.xml.bind does not exist
implements user.UserData, com.sun.xml.bind.RIElement, com.sun.xml.bind.JAXBObject, user.impl.runtime.UnmarshallableObject, user.impl.runtime.XMLSerializable, user.impl.runtime.ValidatableObject
user/impl/UserDataTypeImpl.java:11: package com.sun.xml.bind does not exist
public class UserDataTypeImpl implements user.UserDataType, com.sun.xml.bind.JAXBObject, user.impl.runtime.UnmarshallableObject, user.impl.runtime.XMLSerializable, user.impl.runtime.ValidatableObject
how do I fix this? where do I find sun.com.xml and other related packages could my xaxb.properties have anything to do with this?
Here it is:
#Sun Jan 04 22:52:08 EST 2004
javax.xml.bind.context.factory=com.sun.xml.bind.ContextFactory_1_0_1
com.sun.xml.bind.jaxbContextImpl=user.impl.runtime.DefaultJAXBContextImpl
I am using the web services development pack version 1.3
here's my xsd file
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="userData" type="userDataType"/>
<xsd:complexType name="userDataType">
<xsd:sequence>
<xsd:element name="userInfo" type="userInfoType" minOccurs="1" m
axOccurs="1"/>
<xsd:element name="buddy" type="buddyType" minOccurs="0" maxOccu

<xsd:sequence>
<xsd:element name="userID" type="xsd:unsignedShort"/>
<xsd:element name="userName" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
drop a line if yo have any idea as to how to fix this

I wonder if you come across any soultion or suggestion regarding your problem. I have the same kind of problem you are having eventhough I have copied the JWSDP_HOME\jre\lib\endorsed to my <JAVA_HOME>.
I also updated my CLASSPATH to point to all the required jar files as mentioned in the forum.
The number of errors have reduced, but I am running into the runtime error. Any idea on what the solution is? Thanks.

I am glad your were able to run it. I, however, am
still having problems even after placing all the .jar
files in the jaxb, jaxp, jaxrpc directories in my
path. 100 errors such as
.\primer\po\impl\runtimeDefaultJAXBContextImpl.java:128
cannot resolve symbol
symbol: class Validator
location: class primer.po.impl.runtime.Default
JAXBContextImpl
public Validator createValidator() throws
s JAXBException{
^
...Property Exceptions, and
.\primer\po\impl\runtime\UnmarshallingContext.java:18:
package javax.xml.bind does not exist
import javax.xml.bind.ValidationEvent;
and
.\primer\po\impl\runtime\ValidationContext.java:27:
package com.sun.xml.bind does not exist
import com.sun.xml.bind.ProxyGroup
^
etc...
I will continue searching the forums, and other
sources. Thanks for your help!

  • Unable to compile a package calling a package procedure in different schema

    Hello,
    I'm unable to compile a package referencing a package located in another schema. I get the message: PLS-00201: identifier 'pkg1' must be declared
    Facts:
    0. I'm running Oracle DB 10.2.0.4.0 Enterprise Edition
    1. There is one schema ('schema1') containing a package ('pkg1').
    2. This package 'pkg1' has a public synonym ('pkg1' as well).
    3. The EXECUTE grant is given to a role ('role1').
    4. There is another schema 'schema2', which is granted the role 'role1' (and set as default).
    5. This schema 'schema2' contains a package ('pkg2').
    6. This package 'pkg2' calls a procedure of 'pkg1'.
    7. When compiling 'pkg2', I get error message saying 'pkg1' does not exist.
    Of course, if I execute 'GRANT EXECUTE ON pkg1 TO PUBLIC' or 'GRANT EXECUTE ON pkg1 TO schema2', I can compile the package 'pkg2'. But I don't want this.
    And what's weird is that, connected as 'schema2', I can execute the statement 'execute pkg1.proc1' without any trouble. So I guess the role setup is okay.
    What would let me compile 'pkg2' properly?
    Regards,
    Arnaud

  • Unable to compile a package

    I have a package , it has got only specification.
    When i am trying to compile that package either through command window or SQL developer , i am not able to compile.
    It stucks and the window hangs.
    I have looked  into v$locked_object , and the object is not locked.
    I have tried to compile other objects of same schema and it went successful.
    i am not clear on what could be the reason?
    I am on 11g

    It's already there.
    As i posted , i am not able to compile it through sql developer tool also.ie.UI
    It has got a pragma declared name EXCEPTION_INIT.....
    it declares only exceptions

  • Compile UTL_FILE PACKAGE BODY

    Hi ALL,,,
    I refreshed one db from PROD dump.
    After that I compiled all Invalid objects .But am unable to compile UTL_FILE PACKAGE BODY
    Showing all are invalid.
    OBJECT_NAME OBJECT_TYPE OWNER
    UTL_FILE PACKAGE BODY UTLFILE
    UTL_FILE_EX PACKAGE BODY UTLFILE
    UTL_FILE_ADMIN PACKAGE BODY UTLFILE
    SQL> show parameter utl
    NAME TYPE VALUE
    create_stored_outlines string
    utl_file_dir string
    Please help me how to compile this.
    If I tried to copile manualyy..I am gettimg Error like..PACAGE ALTERED WITH COMPILATION Errors.
    Thanks
    Manohar.

    Invalid objects are best compiled by using
    sqlplus / as sysdba
    @?\rdbms\admin\utlrp
    This will report the number of invalid objects when finishing.
    When you still have invalid objects you should query dba_errors where name='<name of invalid object>'
    All Oracle provided sources are in
    %ORACLE_HOME%\rdbms\admin
    You can simply find or grep for utl_file.
    There always will be two files
    utl<facility>.sql (or dbms<facility>.sql) and prvt<facility>.plb
    You need to run them both in sqlplus connected as sysdba.

    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.       package not found

    Hello folks,
    I was trying to build a simple web application using Eclipse IDE, tomcat 5.x server and ant to build and deploy the application.
    I referenced the following tutorial:

    I was able to create a war file, deploy it in tomcat. When i invoke a simple jsp it works fine. However if I try to import any source pkg into jsp it throws error. Below is stack trace.

    }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...

  • 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.

    import javax.servlet.*;
    core\data\UserPassword.java:package javax.servlet.http does not exist

    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.

    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.

  • 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.

    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>

    Thanks
    Geetha

    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

    just a random guess...
    I had a ton of issues with JBoss and jfreechart. JBoss uses a different classloader, and its internal versions of the jfreechart classes will be loaded before yours, causing all sorts of issues. Dig through the jboss directories and you'll find a different, older version of jfreechart of one of its classes. Remove them and you'll be in better shape.
    Alternatively, look around the JBoss docs for how to disable/turn off the unified classloader for your app (its a directive in jboss-web.xml IIRC). This should make the classloader for your webapp perform to spec, getting rid of the class colission issues.

    ***************** END TOMCAT ERROR MESSAGE *********************

    Hi
    I am running my Tomcat apps (on a Windows dev machine) in an alternate location (ie. not default webapps). The same crap comes to me every time. Unable to install etc. I have tried every trick in the book regarding classpath settings etc.
    When I use 'javap' to check the classpath from any location on my machine, its works and javap returns the signature of my class.
    When I use it though Tomcat (with the import set to include the filename), it get the error. I have heard rumors that using JDK 1.3 in stead of 1.4 helps, but I just want it to work with 1.4 :)
    So if any of you can help me on this, please.
    PS. On my linux server it works just fine, as does every other thing on that machine ;)

    Hi,
    I am using J2EE SDK 1.4 Server and deployed a Stateless Session Bean and used a JSP page as Web Deployment component. When I deploy the application no error is given but when I access application using the given web context name the following error is displayed on the browser.
    type Exception report
    message

    it from fulfilling this request.
    exception
    org.apache.jasper.JasperException: Unable to compile class for JSP
    No Java compiler was found to compile the generated source for the JSP.
    This can usually be solved by copying manually
    $JAVA_HOME/lib/tools.jar from the JDK
    to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
    If using an alternate Java compiler, please check its installation and
    access path.

  • Using javabean in tomcat(unable to compile class)

    A very common question. Tomcat dislikes classes which are not packaged. So, add a package statement in your UserBean.java
    package beans; // or something like thatand then place the compiled class file UserBean.class into WEB-INF/classes/beans.
    Put the import statement into the JSP accordingly and try again.
