Jdev webservice and java.util.Collection

Hi,
i write a web service based on an stateless
session EJB i have 2 method who return double
and they work fine.
But i have added a method who return a Collection and
when i try to regenerate my web service i got
a message error because the return type does not
have an xml chema mapping and/or serializer
specified.
How can i fix this problem ?
I use jdev 9.0.5.2 and oracle 9ias 9.0.4.1.
Thank you for your help.

I'm not a WS PM, but I think the problem here is that a java.util.Collection is a supported type for WS based on the 904 release. From what I remember the supported types are the Java primitives, their wrappers (ie java.lang.Long), java.lang.String, arrays of these and JavaBeans which have fields of these types.
I think if you want to use Collections then you need to use the JAX-RPC enabled Web Services which we provide in the 10.1.3 releases of JDev and OC4J.

Report cannot be rendered (com/sun/java/util/collections/Iterator)

Hello all
I'm new both to Weblogic Server and BI Publisher.
A few days ago I thought that I managed to install BI Publisher on top of Weblogic. It turns out to be untrue because I am not able to view any report, being it a sample or a newly created one.
Platform: Windows 2003 32-bit
Weblogic version: 10.3.3.0
BI Publisher version: 10.1.3.4.1 (doesn't work both w/ and w/o the latest patchset 9791839)
And now to the problem. Whenever I try to view a report, I get an error message stating "The report cannot be rendered because of an error, please contact the administrator". Being both the user and the administrator, I am forced to press the "Error Detail" link, upon which the only thing that pops below is "com/sun/java/util/collections/Iterator" (in red).
The same non-verbose error message appears also when running in debug mode. Weblogic logs are empty from warnings, errors, etc.
As for the Weblogic Server, it claims that the xmlpserver application has been deployed and started successfully.
It seems to me that the BI Publisher application is trying to use java class that doesn't exist (com.sun.java.util.collections.Iterator). Of course I have no clue how to prove that because I do not have the source code for this app.
Oracle support is hardly able to understand the problem, so I thought maybe one of you could give me some answer.
Any Ideas?
Jonathan

By the way, I deployed the app under Oracle Report's cluster. Don't know whether it matters.

ResourceEntityResolver.java referencing com.sun.java.util.collection

Im trying to compile the WL5.1 ResourceEntityResolver.java class but it is
referencing com.sun.java.util.collection package. Where can I find this
package?

This can be an issue when using Tomcat and upgrading version of Mojarra.
Tomcat will store a file with the extension of .ser in the work directory. This file contains the names of the ServletContextListener instances
that need to be invoked when the application is next started. The problem is that if they use the values in that file and the listeners don't
exist, they don't rescan the application to rebuild the .ser, they just fail.
The way to fix this is to search for .ser files in your web container's work directory and the ones for the web application in question.

Why not Deprecate java.util.Date and java.util.Calendar

With the introduction of java.time, why did you not flag java.util.Date and java.util.Calendar. These classes have been a bane to every Java developer and should never be used again with the introduction of Java 1.8.

Adding the @Deprecated annotation would only just provide a warning about an old API and recommendation to the developer(s) to no longer use it. Doing so would not break any existing library out there; in fact quite a number of constructors and methods on the Date class have already been flagged deprecated.
The new java.time package is far superior to Date/Calendar.

JAXB External Binding to java.util.Collection

Hi,
By default jaxb converts xsd:sequence to java.util.List. Is there any way to specify that during compilation it will use java.util.Collection instead of List?

Java.sql.Date and java.util.Date - class loaded first in the classpath

I had two jar files which has java.util.Date and java.sql.Date class file. i want to know whether which class is loaded first in the classpath...
I like to change the order of loading the class at runtime...
Is there is any way to change the order of loading of class...
I may have different version of jar files for example xerces,xercesImpl. some of the code uses xerces ,some of the code uses xercesImpl..i had common classes.
I like to load the class with the same name according to the order i need..
Can we do all these in Run time ?????

The classes you are referring to are part of the Java API. Third party jars have no impact on that. And you can't change to the order because java.sql.Data is derived from java.util.Date. So the second must load before the first.
And if you have two jar files with those classes in them (and not classes that use them) then you either should already know how to use them or you should stop trying to do whatever you are doing because it isn't going to work.

Oracle Timestamp and java.util.date

Greetings,
【Enviroment】
oracle 10g Express
jdbc 10.2.0.1.0 thin driver
windows Xp professinal
【problem】
I fetched a value of timestamp.
And I faced An Error that "java.sql.SQLException: Cannot set lastup_dt: incompatible types."
We define data type of lastup_dt is timestamp on Oracle.
And We define the data type of lastup_dt of javaBean is java.util.date.
And Ocurr SQLException at result = rsh.handle(rs);
How Can I avoid it?
public Object query(Connection conn, String sql, Object[] params,
ResultSetHandler rsh) throws SQLException {
PreparedStatement stmt = null;
ResultSet rs = null;
Object result = null;
try {
stmt = this.prepareStatement(conn, sql);
this.fillStatement(stmt, params);
rs = this.wrap(stmt.executeQuery());
result = rsh.handle(rs);
} catch (SQLException e) {
this.rethrow(e, sql, params);
} finally {
try {
close(rs);
} finally {
close(stmt);
return result;
Any help I appreciate it.
Thank you.

As long as you have the long representation of the time you can create a new java.util.Date:
new java.util.Date(ts.getTime())

SOAP, webservice and JAVA

Hi, all,
If there are two different business systems need to exchange data, after sending and receiving messages, they both have to update their database. Do you think directly using JDBC adapter to insert/update each other's tables is a secure and effient way? Or using JAVA/APAB proxy to send out data, then using SOAP adapter to receive the data, and then using Java program to update database is much better? Can anybody provide any sample scenario and Java programs for the later? Any comment will be highly appreciated!
Marea

Hi Marea,
I am slightly confused with your question... Anyways i have given you all the info regarding JDBC Adapter and how it actually works...
A JDBC sender adapter has 2 essential fields,
1. SQL Statement
2. Update Statement
Your SQL statement will contain your SELECT statement and once your SQL statement is executed, UPDATE statement is executed. This is done so that records that have been selected by the SQL statement should not be selected again as the JDBC sender adapter will poll over the database for every poll interval.
If you want to SELECT something from your Database, then you will have to go for a JDBC sender adapter.
But, if you want to insert/update your Database, then you can go for a JDBC receiver adapter.
Multiple insertions are possible for a JDBC receiver, but multiple Selection queries (different select queries) are not possible for a single JDBC sender adapter.
Just check these links to understand how JDBC adapters work,
If you wanna do update/insert you will have to follow the
<a href="http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm">Document Formats for the Receiver JDBC Adapter</a>
For Configuring the Receiver JDBC Adapter refer:
<a href="http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/content.htm">Configuring the Receiver JDBC Adapter</a>
For Configuring the Sender JDBC Adapter refer:

To access any Database from XI, you will have to install the corresponding Driver on your XI server.

Or on the JDBC end you can write a stored procedure to make your data update more efficient.

Java5 printf and java.util.UnknownFormatConversionException: Conversion = '

As a long time C/C++ programmer I was pleased to see printf added to Java5, however one of (IMO) the most useful features - using an asterisk in the format string to indicate a fields width modifier is to be taken from the varargs list doesn't appear to work:
Given:
     #include <stdio.h>
     int
     main()
             printf("[%*d]\n", 8, 2);
             return 0;
     }I get:
     [       2]
However, given:
     public class Main
         public static void main(String[] args)
             System.out.printf("[%*d]\n", 8, 2);
     }I get:
     Exception in thread "main" java.util.UnknownFormatConversionException: Conversion = '*'
          at java.util.Formatter.checkText(Formatter.java:2500)
          at java.util.Formatter.parse(Formatter.java:2482)

          at Main.main(Main.java:19)
     Process finished with exit code 1Not at all the same thing.
It fails on Windows and Mac.
The way I read the documentation I believe this should work.
Am I misinterpreting the doc, doing something wrong, or is this a bug?
Thanks!

Thanks, I understand that. What I am referring to is this from the docs:
http://sharkysoft.com/archive/printf/docs/javadocs/lava/clib/stdio/doc-files/specification.htm
1.3.1. variable width
It is possible to specify a variable field width, where one of the arguments in the argument vector is used to determine the field's width. This is indicated in the format string by using an asterisk character ('*') in place of the actual width value. The corresponding value in the argument list must be an int, and must precede the actual argument being formatted.
Example: If the format specifier is "%*hd", then there are two arguments in the argument list corresponding to this format specifier. The first argument is an int, indicating the field width, and the second argument is converted as a signed short.

Synchronized and java.util.ConcurrentModificationException

Hi,
I keep getting a java.util.ConcurrentModificationException when running the following code:
ArrayList tObjects = ...
synchronized (tObjects) {
Iterator tObjectsIterator = tObjects.iterator();
while (tObjectsIterator.hasNext()) {
Object tObject = tObjectsIterator.next(); -----> Exception
I run synchronized on tObjects so I can't understand why (and how) I get the Exception, can anyone help?
Thanks,
Iggy

thanks for the help, I still have some difficulties:
I have a (static) class ObjectsHolder which holds an ArrayList tObjects, I have various methods that access the ArrayList and return one/some elements.
I would like to synchrinize on the ArrayList tObjects in ObjectsHolder, but the holder returns the ArrayList itself I am unsure whether the access to the ArrayList will be synchronized even in the calling method.

Can not create WebService with java.util.Locale object why?

I am unable to create a WebService which contains a Locale Object in the request. I assume its because the java.util.Locale object is not Serializable. Can anyone tell me if there is a work around for this?

Hi,
Make sure your strings for Locale follow these rules...
The language string should be lower-case, two-letter codes as defined by ISO-639.
http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt
The country string should be upper-case, two-letter codes as defined by ISO-3166.
http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html
Or try with some constant Locales like
Locale.CANADA
Locale.US
