Handler class

Can a JAX-WS handler alter SOAP message ? In other words, can we modify the SOAP message using JAX-WS handler ?
I'm aware of that these can used to manipulate messages. What are the possible permissible manipulations?
encryption ? modify messages ?

How to Modify Override Handler class in jsse.jar

Hi,
Is there a way to change port number in Handler class in jsse.jar and recompile the Java file, or override the class?
The Handler class seems to be using port number 443, whereas the the Webserver of PS Application is using a different port number (7004).
Any ideas.
Thanks
Jay

You're over-thinking this. The Handler class uses whatever port it is told to use by the person that constructs it. 443 is just the default.
All you have to do is put the required port number into the https URL, e.g. https://www.myhost.com:7004.

A parent folder must have set workflow configuration to be final - thus preventing any sub-folders from changing the policy.
Work your way through the various parent folders (via Web UI), and ensure "Do not allow subfolders to modify this operation's workflow settings" for the particular workflow/operation combination is not set.

JSF 1.2 tag handler classes in JSF 1.1 environment

Hi,
Im developing a JSF 1.2 application with RSA 7.5.1. When I run it in the WAS 6.1 I get the following exception:
javax.servlet.ServletException:
Unable to convert string '#{onebean.onestring}' to class
javax.el.ValueExpression for attribute title:
java.lang.IllegalArgumentException:
Property Editor not registered with the PropertyEditorManager
at org.apache.jasper.runtime.PageContextImpl.handlePageException
(PageContextImpl.java:660)etc...
I think my WAS 6.1 running environment doesnt admit Tag Handler classes in JSF 1.2 style (you know: Extending UIComponentELTag, with all attributes in the tag class of type valueExpression along with setter methods...).
In case this suspect is true, is there any tricky way to run this JSF 1.2 components in a JSF 1.1 environment?
Do you have any ideas to solve this problem without downgrading my JSF tag handler classes from 1.2 to 1.1?
Thanks a lot!

Hi BalusC,
This is the full history:
I started coding the tag handler classes of my JSF components in the JSF 1.2 way.
But know, Iam being forced to run the web app that uses those JSF 1.2 components in a WAS 6.1 (servlet 2.4 & jsp 2.0, I suppose).
Not very elegant solution, I put a servlet2.5-jsp2.1-api.jar file in my WebContent\WEB-INF\lib directory, and configured a PARENT-LAST class loader policy in the server configuration.
This is my web.xml:
<?xml version="1.0"?>

Tag Handler Class classpath

          Hi.
          I have some problems with Tag Handler Classes in custom tags. When tag handler
          class store in package all is OK - I place it's class-file in /WEB-INF/classes/%package-path%/%class-name%.class
          and in tld-file in <tagclass> write: %package-path%.%class-name%.
          When tag handler class don't store in package I place class-file in /WEB-INF/classes/%class-name%.class
          and in tld-file in <tagclass> write: %class-name%, but it's doen't work. When
          jsp starts I recieve:
          D:\bea\wlserver\config\mydomain\applications\.wl_temp_do_not_delete\WEB-INF\_tmp_war_myserver_myserver_CustomTag\jsp_servlet\_simpleexample.java:81:

          ExampleTag csajspexample0 = null;
          ^
          Why? Plese, help me.
          Igor


You probably should not use unnamed packages at all.
          Language spec specifically says that "Unnamed packages are provided by the
          Java platform principally for convenience when developing small or temporary
          applications or when just beginning development."

How to access SOAPAction in Handler class ?

How do I access the SOAPAction in a handler class? I've tried to get the SOAPACTION_URI_PROPERTY
from the SOAPMessageContext, but the value is null.

Thanks Christian -- that worked great.

Hi Nancy,
the SOAP Action is a HTTP Header field:
http://www.w3.org/TR/SOAP/#_Toc478383528
So it should be possible to get this information through the
getHeader() or getHeaders() method from the HTTPServletRequest
http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/http/HttpServletRequest.html#getHeader(java.lang.String)

Tool to downgrade Tag handler classes from JSF 1.2 to JSF 1.1

I am not sure if I understand you, but what's wrong with just replacing the JAR files?

JWSDP Custom Tags (finding tag handler class)

Hi,
ive been using the Java Web Services Development Pack
ive tried several examples of creating custom tags all seem to have different directory structures and none seem to work. Heres my setup...
rootdir -> index.jsp
rootdir -> WEB-INF -> web.xml
rootdir -> WEB-INF -> tlds -> demo.tld (the tag library descriptor)
rootdir -> WEB-INF -> classes -> demo -> tags -> Greeter.java (the tag handler class)
there are some other folders created by deploytool but they are empty.
heres demo.tld...
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>2.0</jsp-version>
<short-name>demo</short-name>
<uri>DemoTags</uri>
<tag>
<name>greeter</name>
<tag-class>demo.tags.Greeter</tag-class>
<body-content>empty</body-content>
</tag>
</taglib>
here is the tag handler class Greeter.java...
package demo.tags;
import javax.servlet.jsp.tagext.*;
import javax.servlet.jsp.*;
public class Greeter extends SimpleTagSupport {
public void doTag() throws JspException {
PageContext pageContext = (PageContext) getJspContext();
JspWriter out = pageContext.getOut();
try {
out.println("Hello World");
} catch (Exception e) {
// Ignore.
and heres the code in index.jsp...
<%@taglib prefix="t" uri="DemoTags" %>
<t:greeter />
Id love to know if these directory structures are fixed and where they are specified - its confusing the way so many examples show differences.
this is the exception i get when trying to run index.jsp through the admin page (localhost:4848)
org.apache.jasper.JasperException: /index.jsp(11,0) Unable to load tag handler class "demo.tags.Greeter" for tag "t:greeter"
----

Sincere Apologies - It might be a good idea to compile my java files so i actually have classes in my classes directory !!
i think a build.xml file is needed for ant to compile everything that is needed now.
and the beat goes on !

Customised Exception handling class.....

Hello Friends,
I am working on a project for which I need to create my own exception handling class.
The reason I need this class is to catch any exceptions and get a customised error message
according to each exception and then be able to display those messages on web page.
some examples of the exception I want to catch and display appropriate message are..
1. a duplicate reord in db
2. wrong data type (this will deal with ints,doubles and strings data types)
3. date type validation ( to make sure its date object instead of a string)
and there are several more messages but if can get some help or idea from any one to design a class for the above errors I might be able to manage other errors as well.
greatly appreciate any respnses.

First off, you can extend Exception:
public class MyException extends Exception {
}You can put some custom messages into the class:
public class MyException extends Exception {
public static final String DUPLICATE_RECORD = "Duplicate record in db",
                       WRONG_DATA_TYPE = "Wrong data type",
                       VALIDATION_ERROR = "Invalid data type";
}Then, have your constructors, which take a String as an argument, so they can get your 'presets' or a custom message:
public class MyException extends Exception {
public static final String DUPLICATE_RECORD = "Duplicate record in db",
                       WRONG_DATA_TYPE = "Wrong data type",
                       VALIDATION_ERROR = "Invalid data type";
public MyException(String message) {
    super(message);
}You could also have a series of exception classes: DuplicateRecordException, WrongDataTypeException, ValidationException, etc. Hope that helps.

Missing Class error from handler class - urgent question!

Hi,
I am getting an "Missing Class" error when running a web service. The web service was generated from a Java class via the "create J2EE web service" option.
The web service has a JAX-RPC handler class added, which belongs to the same package as a logging class. The logging class is used to write to a file for debug purposes. A "missing class" error is being generated whenever I attempt to invoke the web service (via the enterprise manager test util), the error refers to the logging class which is used by the main handler class. The JAX-RPC handler works fine by itself, the error is only seen when I attempt to use the logging class.
I have re-built, re-deployed from scratch again, but still get the same error! Am I missing something simple here?
thanks for any advice

Hello,
I have posted something similar, but I am not sure how to get over this issue. I am not sure if this is a code issue, I have scanned both EJB 2.0 and 2.1 specifications, but nothing caught my eye.
Here is the error I am getting starting this in JDeveloper 1013 :
Apr 11, 2006 12:17:49 AM com.evermind.server.Application setConfig
WARNING: Application: current-workspace-app is in failed state as initialization failedjava.lang.InstantiationException: Error initializing ejb-modules: [current-workspace-app:CNSI-JDev-7_Exp-7_0:DbUtilWrapper] - Unable to load ejb-class com.my.common.database.ejb.DbUtilWrapperBean, see section 23.2 of the EJB 2.1 specificationjava.lang.ExceptionInInitializerError: java.lang.NullPointerException
Here is the ejb-jar.xml :
<session>
<description>Session Bean ( Stateless )</description>

<ejb-class>com.my.common.database.ejb.DbUtilWrapperBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
I am not sure if this should be in the assembly-descriptor, in ejb-jar.xml or orion-ejb-jar.xml :
<method-permission>
<unchecked/>
<method>
<ejb-name>DBUtilWrapper</ejb-name>
<method-name>*</method-name>
</method>
</method-permission>
Any ideas ?
Thanks

Own connection handling class

hi all,
In the jdbcpds.conf file, it is mentioned that we can write our own connection handling class which extends the provided JDBCConnectionHandling class
What i tried after looking at the methods of connection handler is something like this
class myJDBCConnectionHandling extends JDBCConnectionHandling
protected void parseConnectInfo(String s, JDBCConnectDialog jdbcconnectdialog, Plugin plugin)
throws Exception
String dbUrl = null;
dbUrl = "<user>/<pwd>@<remotedatabase>";
super.parseConnectInfo(dbUrl, jdbcconnectdialog, plugin);
Is there anything else that needs to be done
because this is throwing an error
JDBCPDS-62008 : Failed to connect to the datasource null
Invalid arguments in the call
Can anybody correct me
Of course my main purpose of trying this is to have something like a logical name given to the P_JDBCPDS parameter which can be mapped to the actual database url using JNDI lookup.
what i was expecting was, the string when passed to the connection handler, i can add the code to lookup the name in my own connection handler and leave the rest to the provided JDBCConnectionHandling class
Am i going in right direction or not
Or if anybody has any other solution you are welcome to suggest
Any sort of help is greatly appreciated
Thanks in advance
Ramakrishna

hi,
One more thing i forgot to mention was that i am not too concerned about this lookup in reports builder
I need when this is running on the server
thanks & regards

Error in custom error handler class

Hiii...
i got some error s when i create error handler class
i use the following code for creating that class
package view.controller.fwkext;
import java.util.ArrayList;
import java.util.List;
import oracle.adf.model.binding.DCBindingContainer;
import oracle.adf.model.binding.DCErrorHandlerImpl;
import oracle.jbo.CSMessageBundle;
import oracle.jbo.DMLConstraintException;
import oracle.jbo.JboException;
public class CustomErrorHandler extends DCErrorHandlerImpl {
List<ExceptionMapper> exceptionMapperList = new
ArrayList<ExceptionMapper>();
public CustomErrorHandler() {
this(true);
public CustomErrorHandler(boolean setToThrow) {
super(setToThrow);
exceptionMapperList.add(new DisableJboExceptionCodesMapper());
public void reportException(DCBindingContainer bc, Exception ex) {
for (ExceptionMapper mapper : exceptionMapperList) {
if (mapper.canMapException(ex)) {
ex = mapper.mapException(ex);
super.reportException(bc, ex);
I got errors
DisableJboExceptionCodesMapper not fount
canMapException not fount
mapException not fount

Abhilashs01,
Yes, that example from the docs appears to be missing a few things, to-wit: the ExceptionMapper class and the DisableJboExceptionCodesMapper class. Without the ExceptionMapper class, JDeveloper's import assistance is finding one in com.sun.jndi somewhere, which is obviously the wrong one. So, yes, the docs are good, but they appear to be missing some key things, making it kind of hard...
Another place to find an example error handler class is in the Fusion Order Demo: http://www.oracle.com/technology/products/jdev/samples/fod/index.html
