Data Pump and Java Classes

I tried importing the data from one schema to another but the Java classes that we use (via Java Stored Procedures) are showing up as invalid. Is there any reason why? We are using Oracle 10g R2. I tried resolving them by running the following sql, but that didn't work either:
ALTER JAVA CLASS "<java_clss>" RESOLVER (("*" <schema_name>)(* PUBLIC)) RESOLVE;
Any thoughts will be appreciated.

There are two ways to instantiate a target's data. One is to use a native data loader or utility. In Oracle's case, Oracle Data Pump (not the "data pump" in GG) or SQL*Loader, as an example. The other way is to use GoldenGate's data pump.
You can configure DDL synchronization for Oracle, but you have to turn off the recycle bin. See Chapter 13 in the admin guide.

Mapping data model to java classes and Interface.

Need help in mappning my data model into java classes;
Here are some of the details:
Table, Poll:
PollID int
PollName varchar
BusinessUnit varchar
DisplaySchemeID int // reference to DisplayScheme table.
Table, DisplayScheme
DisplaySchemeID
DisplaySchemeName
etc
Table, URL
UrlID
UrlName
UrlDesc
Table, PollURL
PollURLID
PollID
UrlID
PublishDate
etc
Table, Tag
TagID
TagName
PollID
So, a POLL is associate with a DisplayScheme.
A Poll can have many URLs and a URL can be associate with many Polls , mapped in the PollURL table.
and same is the situation with tags.
Essentially I want to learn how to do one to many mappning and many to many mapping.
Also to add, since I plan to use Ibatis for OR mapping.
So I should a Parameter call to map for creaint a Poll. And to create a poll the form submitted will have:
- PollName
- URLs ( multiple )
- one display scheme.
- Tags ( many )
So if you can show how to write a DAO createPoll method, then it would be great.
Not sure if am asking a lot, but this would be a great example to move forward.

The below is the sample DAO Class.
For your case, you have to create your own PollBean with getters and setters and just pass the object to the method
public int create(Connection con, ProjectBean projectBean) throws SQLException {
          int result = 0;
          String insertQuery = " INSERT INTO" +
                    " M_PROJECT(" +
                    " PROJECT_ID," +
                    " PROJECT_NAME," +
                    " PROJECT_DESCRIPTION) " +
                    " VALUES(?,?,?,?)";
          initPrepareStmt(con, insertQuery);
          setString(projectBean.getProjectID());
          setString(projectBean.getProjectName());
          if(projectBean.getProjectDescription().equals("")){
               setString(" ");
          }else{
               setString(projectBean.getProjectDescription());
          result = executeUpdate();
     return result;
     }

Passing variables between data tag and Java

Hello all,
I have a question about using variables between data tag and java.
Let me explain.
I would like to populate variable "Test" with
the information returned by jbo data tag library.
<code>
<% String Test = "%><jbo:ShowValue datasource="ds" dataitem="Cod" /><%";%>
or
<% String Test = "<jbo:ShowValue datasource="ds" dataitem="Cod" />";%>
</code>
This code did not work.
Some suggestions
Thanks

Humberto,
I'm afraid I do not know the specific answer
to your question (perhaps Juan the Data Tag
Wizard will reply ;-). I vaguely recall
struggling with teh same issue when I was
playing with the tags for a demo. Here
is a hack-around lifted from my demo
that might help:
<jbo:Row id="privRow" action="CURRENT" datasource="privileges" />
<%
String privName = (String)privRow.getAttribute("Privilegename");
%>
In other words, I ended up using the Row
tag to get a local Java variable bound to the
row instance and then used its methods
to extract the value. I presume the class
of the row instance is oracle.jbo.Row
and you can lookup its supported methods
in the reference doc.
I'd be interested to hear if their is a more
elegant way - the one suggested above is
pretty tedious.
Regards,
Bill

(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.

Deploying the JSPs, Servlets and Java class files

Hello All,
I'm very new to the Oracle 9i AS. We are using Version 1.0.2.2.
How do we deploy the JSPs, Servlets, and Java class files (simple class files, not EJBs)?
plese give us the procedure and stpes how to deply or the links for the same.
Thanks,
Santhosh.

Hi
I guess u r running apache-jserv as servlet engine for your jsp and servlets. If its so, jsp files can be run without any additonal configuration by putting the jsp file under document root or any subdirectory and for running servlets u have to add classpath entries for your servlet in jserv.properties file.
To make sure that your servlet engine is working, try
http://servername:port/servlet/IsItWorking, if u get success msg that means servlet engine is working fine.
Hope this will help

Problems with data controls from java classes in JSF pages.

Hi! We have a problem in our Application that we are developing with JSF pages using Data Controls generated from facades java classes. When we running a page in debug mode and the page are loading, if we insert a breakpoint in the first line of method referenced in the data control, the execution enter two times in the method, and this is a problem for us. How to solve this?
We are using JDeveloper 11.1.1.2 with ADF faces.

You might need to play around with the refresh property of the action binding.

How to used a JCR Data Control in Java class?

Hi,
I created a JCR Data Control to my UCM to obtain a treeTable with the datas. But it's impossible to create a treeTable like i want to.
So I know how to create a treeModel to obtain the treeTable I want.
Is there a way to used the getItems method of the dataControl in a Java Class?
I tried this :
BindingContext bc = (BindingContext)JSFUtils.resolveExpression("#{data}");
DCDataControl dc = bc.findDataControl("UcmDC");
But dc is null.
There are some xml files (UcmDC.xml or getItems_return.xml). Is it a way to resolve my problem. And if so, how do I use?
Best regards,
Thomas

Data Control from Java Class

Using JDev 11gPS4
I have a java class that i want to use as a DC:
(simplified)
public class AccountDC {
    public AccountDC() {
        super();
    public void insertAccount(Account account){
        //Do some things
}Account:
public class Account {
    private String name,alias;
    public Account() {
        super();
    public void setName(String name) {
        this.name = name;
    public String getName() {
        return name;
    public void setAlias(String alias) {
        this.alias = alias;
    public String getAlias() {
        return alias;
}When I create the data control from the first class, i get the insertAccount operation.
When i drop the account parameter on my JSPX page, JDev suggest an ADF Form which is fine.
When I drop the insertAccount method below the form, JDev suggest an ADF Button which is also fine.
JDeveloper doesn't seem to know that the values provided in the above form should be mapped to an Account object for the insertAccount.
How should I do this?
In the bindings I do have the individual attributeValues for each attribute but I don't seem to have a reference to an Account object. Do i need to add something to my DC?
Another question... Is it maybe better to create a VO with only transient attributes and an Application Module where i expose my own custom createInsert method?
It's all custom code. It does not write anything to a database.

You should have an object that represent your method's parameter in your data control - if you'll drag it into your page you'll get the fields needed.
Similar to the way it is done in this example:
http://blogs.oracle.com/shay/entry/updateinsert_with_adf_web_serv

Passing data to a java class

I've recently been working on a page that displays a list of objects using the h:dataTable tag. In each row of this table I display the name and group properties of a bean called "ace", as well as a command button next to each of them.
What I want is when one of these buttons is clicked, a java class will be able to grab the name and group in the row containing that button.
My question is this: how do I pass the name and group for that row to a java class?
Here is the data table in question:
<h:form>
<h:dataTable id="ACLTable" value="#{aclBean.aceBeans}" var="ace">
          <%-- name --%>
          <h:column id="aceName">
               <f:facet name="header">
                    <h:outputText value="#{msgs.aclTableObjectHeader}"/>
               </f:facet>
               <h:outputText value="#{ace.name}"/>
          </h:column>
          <%-- group --%>
          <h:column id="aceGroup">
               <f:facet name="header">
                    <h:outputText value="#{msgs.aclTableGroupHeader}"/>
               </f:facet>
               <h:outputText value="#{ace.group}"/>
          </h:column>
<%-- submit button --%>
<h:column>
<h:commandButton id="aceSubmit"/>
</h:column>
</h:dataTable>
</h:form>

Gowtam,
Are you sure that the HashMap object is available for GC at the end of your controller code?
If your JVM Heap is relatively small compared to the size of your HashMap, then you can hit this issue. Analyze, if you really require such a huge collection on objects to work on, if there is no other alternative, then go ahead and do a memory turning to find out the optimum memory requirement / user and tune your JVM accordingly.

Problem viewing data through autogenerated java class

I have a AQ created with a custom data types as below.
User type definition
type clr_msg_type as object(
firm_id number,
b_com_id number,
cl_com_id number,
action varchar2(15),
action_id varchar2(15),
user_id varchar2(30),
clr_status varchar2(20),
p_id number,
message_type varchar2(50) );
I am having issues with viewing the above object which is the payload on the AQ.
I see "???" for all the variables except b_com_id,cl_com_id and firm_id. rest of the variable I see as "???" when I try to run the debugger.
To map the above object I used jpublisher to auto generate the java class which has getters and setters for the above variables.
I used below command to generate the class.
jpub -user=username/password -sql=CAT.CLEARING_MSG_TYPE -case=mixed -usertypes=jdbc -methods=false -url=jdbc:oracle:thin:@192.134.124.210:1450:dev5
I have below files in my classpath.
C:\oracle-jpublisher\sqlj\lib\translator.jar;C:\oracle-jpublisher\sqlj\lib\runtime12.jar;C:\oracle-jpublisher\sqlj\lib\
ojdbc14.jar;C:\oracle\product\10.2.0\client_1\jlib\orai18n.jar;
I can view data in the below variables:
firm_id number,
b_com_id number,
cl_com_id number,
But I see "???" in the below variables:
action varchar2(15),
action_id varchar2(15),
user_id varchar2(30),
clr_status varchar2(20),
p_id number,
message_type varchar2(50) );
Any idea why this is happening?

if the data is there ( and I can't see why it's not) then the issue is actually printing it on the paper and the issue may be with the font not working with this printer if the static text always prints ( and is in BOLD) then lets just try that and if it works and you can verify that is the issue then you will know where to solve the issue.
as someone** else has posted elsewhere debugging is a case of divide and conquer. (**Michael Meyers-Jouan)

Timezones and Java Classes

I'm trying to pro-actively solve the timezone issue of
capturing and displaying data in local time for a global audience.
I found the timezone.cfc stuff (which looks like it should do a
great job), but can't seem to get it to initialize.
When it makes the call:
variables.timeZone=loader.loadClass("com.ibm.icu.impl.OlsonTimeZone").newInstance();
I get:
13:07:31.031 - java.lang.ClassNotFoundException - in
D:\Development\Serebra\TESTtimezone\REMOTEicu4jTZ.cfc : line 60
com.ibm.icu.impl.OlsonTimeZone
I'm initializing things with:
tz=createObject("component","REMOTEicu4jTZ").init("D:\path\to\jarfile\TESTTimezone\icu4j- 3_6");
I'm new to calling Java classes as objects, so it's entirely
possible I've screwed something up. Anyone have any pointers, or
even tips on how to ask the right question?

1) get & install mark's javaLoader CFC from
http://javaloader.riaforge.org/
2) get the newest timezoneCFC from
http://www.sustainablegis.com/projects/tz/testTZCFC.cfm
3) read the readme file & make the modifications to the
init method to point to
where you put the javaLoader CFC & icu4j jar (it probably
won't be named icu4j.jar).

Create data control from java class, not see "ADF Parameter Forms" option

Hi,
I have created a Fusion Web Application (ADF) in jdev 11g. In the application model project, I created a java class. Inside the java class, I have a public method as below
public Asset [] searchAsset3(SearchTerm s) // SearchTerm is a java bean. It implements java.io.Serializable.
I created data control from my java class. After that, I see an xml file generated under the same folder of my java class. Here is the xml content.
<?xml version="1.0" encoding="UTF-8" ?>
<JavaBean xmlns="http://xmlns.oracle.com/adfm/beanmodel" version="11.1.1.53.62"
id="AIAAsset" Package="oracle.apps.aia.oer.model"

<ParameterInfo id="name" Type="java.lang.String" isStructured="false"/>
<ParameterInfo id="version" Type="java.lang.String" isStructured="false"/>

</MethodAccessor>
<MethodAccessor IsCollection="true"

<ConstructorMethod IsCollection="true"
Type="oracle.apps.aia.oer.model.AIAAsset"
BeanClass="oracle.apps.aia.oer.model.AIAAsset"
id="AIAAsset"/>
</JavaBean>
Then, in application user interface project, I created a JSPX page. From the data controls palette, I want to drag and drop the searchAsset3 onto my page. However, I don't see an option for me to choose "Create -> Parameters -> ADF Parameter Form". I only see "Create -> Methods". Unlike other public methods (e.g.searchAssetSummary and searchAsset) which have simple data type as input, I can see the "Create -> Parameters -> ADF Parameter Form" option when I drag and drop to my jspx page. Is that something I missed while creating data controls?
Thanks.
Arnold.

Then, my other question is how do you do the bindings? I drag and drop the attributes from SearchTerm bean. Now the pagedef file has the AttributeValues added but my method is actually expecting one input parameter of type SearchTerm. How do you bind the attributes to the input of the method? Thanks.
See below of my pagedef xml file.

Getting The SAP KM data in a java class

Hi Everyone
                I want to get the SAP KM data to a simple java class......I am able to get this with servlet but i want not a servlet but a simple java class that can get the Documents stored in SAP KM repository..................
I am thinking of using any java Driver in some code like
Class.forName ("com.sap.dbtech.jdbc.DriverSapDB");
                    String url = "http://host name :port";
                    Connection con = DriverManager.getConnection (url, "", "");
                    Statement stmt = con.createStatement ();
               IUser serviceUser = WPUMFactory.getServiceUserFactory().getServiceUser("cmadmin_service");
               ResourceContext c = new ResourceContext(serviceUser);
               IResource r = ResourceFactory.getInstance().getResource(RID.getRID("/documents/Public Documents/"), c);
               System.out.println("Current user   "+r.getContext().getUser().getDisplayName());
               System.out.println("Current user : "+r.getContext().getUser().getDisplayName());
               System.out.println("Access RID : "r.getAccessRID().toString()"<br>");
But the above code is giving an exception---java.sql.SQLException: No suitable driver
Can anyone tell me the suotable Lava driver to access SAP KM repository..Or any simple java code that can connect to SAP KM...
Waiting for Ur reply
Thanks & Regards

Using oracle.sql.BLOB data type in Java Class to pass in a Blob

All,
I'm trying to pass in a BLOB from PL/SQL to a Java Class, but the BLOB isn't passed correctly.
When I check the length of the BLOB in PL/SQL its different from the length of the BLOB in java.
I'm using DB 11g and the ojdbc5.jar file in my java classes.
The java function uses the oracle.sql.BLOB type to get the parameter.
The java class is loaded into the DB and called via a PL/SQL function.
Kind regards,
Nathalie

The question is indeed a little ambigious defined ;o)
When I pass the BLOB to the java method and invoke BLOB.getBytes() and then get the length of the BLOB in java the length of the BLOB is bigger than in PL/SQL.
When I use the method 'getBinaryStream' and write this to a buffer, the code works.
I will log a tar regarding the getBytes()-method to ask for more detailed information regarding the methods provided using the JDBC Drivers.
Kind regards,
Nathalie
