- JAX-RPC: Strange Exception with Dynamic Proxy ClientHello there
I am using currently SUN's Webservice Development Kit 1.4 and try to
realise a JAX-RPC "rpc/encoded" webservice.
My applicatio is currently running if I am using a static client
(stubs geenerated by wscompile). If am going forward to use a dynamic
proxy client, I am getting a strange exception during the
deserialization of the xml data on the client: "trailing block
elements must have an id attribute". see stack trace at the end of the
messsage.
As far as I understand is that it must somewthing be with the
"ArrayList" or arrays which I am using in my JavaBean which I sent
from the server to the client. Here my extract from my JavaBean:
public class Article
{
long id;
Date date;
String category;
String title="";
String lead="";
List texts;
}
If I am taking out the member "List texts" then it will work
correctly. The list contains only Strings. I tried also to use
String[] array, but this didn't help either.
So here, my questions perhaps someone has some ideas what I did wrong.
- Why does it work with the stastic cleint but not with the dynamic
proxy?
- Does anybody know an example on the net where in JavaBeans Lists or
Arrays has been used?
- Anybody an idea why this error appears? Did I something wrong?
Thank you in advance

- [RFE] Access to Field, Method and Constructor without the use of Strings
Hi all,
I submitted the following RFE to Sun's RFE page.
As a reply I received a mail from Girish Manwani at Sun that I
should start a discussion in one of the Java newsgroups (Huh?).
To my knowledge, this is the most appropriate group. Here gos:
A DESCRIPTION OF THE REQUEST:
It should be possible to obtain references to Field, Method and
Constructor objects without the use of strings. Proposed syntax:
// Assuming the following class
public class Foo {
String bar;
public Foo(String bar) {
this.bar = bar;
}
public void fly(String to) {
bar = to;
}
}
Field fooBarField = Foo.class.bar.field;
Method fooFlyMethod = Foo.class.fly.method(new Object[]{String.class});
Constructor fooConstructor = Foo.class.constructor(new Object[]{String.class});
There are other possible options for the syntax. I would just like to see
this principally possible.
The construct is similar to the ClassName.class syntax and it can be treated
by the Compiler in the same way:
It could produce the getDeclaredField, getDeclaredMethod and getConstructor
bytecode. No modifications to the JVM would be necessary.
JUSTIFICATION :
The existance of the field/method/constructor could be checked during compile
time. Typos would no longer be possible.
A notation without strings could be very easily refactored by IDEs.
We would specifically need the feature for our typesafe querying system,
so it could work completely without strings.
http://sodaquery.sf.net/
The possibility to get Method objects without strings, would encourage many
developers to use them for more dynamic programming and would result in lots
of more flexible libraries for the Java platform.
Thanks in advance for your attention and for positive comments.
Kind regards,
Carl

- [ANNOUNCE] Apache Derby 10.4.1.3 releasedThe Apache Derby project is pleased to announce a new feature release
of Derby, 10.4.1.3.
Apache Derby is a subproject of the Apache DB project.
Derby is a pure Java relational database engine which conforms to the
ISO/ANSI SQL and JDBC standards. Derby aims to be easy for developers
and end-users to work with.
Derby 10.4.1.3 can be obtained from the Derby download site:
http://db.apache.org/derby/derby_downloads.html.
Derby 10.4.1.3 introduces the following new capabilities:
* Asynchronous Replication
Allows you to maintain an up to date copy of your (master) database on
a different host (the slave). In the case of a crash on the master
database you can perform failover to the copy (slave database) and
continue serving client requests against your database.
* Security
o Shutting down the Network Server now supports user authentication,
and in fact requires credentials when authentication is enabled.
* SQL
o Table Functions. Using table functions and standard SQL, you can pose
sophisticated queries against in-memory collections, flat files, web
resources, non-relational databases, etc.. Table functions also let
you efficiently import data from web feeds, sensor logs, and other
relational databases.
o Unique constraints on nullable columns.
o SQL ROW_NUMBER() window function, (for an empty, inlined window
specification).
o Bracketed comments (/* ... */).
* Performance and Memory Usage
o New buffer manager with better concurrency.
o Statement cache in the client driver.
o Caching of isolation level and current schema in the client
driver.
* Administration
o Java Management Extensions (JMX) for Derby, allowing
local and remote monitoring and management of running Derby instances
(embedded or Network Server).
o Continuation prompt. ij adds a short "> " prompt to the next line
after a newline has been entered by the user without ending the
statement with a semicolon.
Derby 10.4.1.3 also has many bugfixes, including the fix for
DERBY-3347 which can cause unrecoverable database corruption. All
10.3 users are encouraged to upgrade to avoid potential corruption
issues.

- Certificate Login ModuleHi All,
If I am correct JBoss has added a SSL certificate login module in
version 4.0. I wanted to have a peek in it, but the source code of JBoss
4.0 is not available.
Can anybody please let me know from where can I get the source code of
JBoss 4.0? Or better, can anybody please send me the source code of such
a Login Module.
Any pointers in this direction will be highly appreciated.
Thanks in Advance,

- IE AutomationI am working on developing a test application in java. I use java for UI
only. I use JNI to communicate with a VC MFC DLL. I launch an IE browser
instance in one JNI method (init()), which works fine.
OleInitialize(NULL);
CLSID clsid;
CLSIDFromProgID(OLESTR("InternetExplorer.Application"), &clsid);
HRESULT hr = CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER,
IID_IWebBrowser2, (void**)&m_spBrowser);
I store the browser pointer (IWebBrowser2 *) as a C++ class instance
variable. BTW, I start a
thread on the native side (_beginthread) which in turn calls the method that
launches the browser.
Previously I was facing the problem of marshalling, the IWebBrowser2 pointer
was getting correupted, when used in different methods (even the simple
properties of IWebBrowser2 (like IWebBrowser2::fullname) were not
accessible). So now I have added the code of marshalling after the browser
is launched. In almost all the other methods, I first unmarshall the
interface and then marshall it back at the end of it. This solved my earlier
mentioned problem.
void CIECanvas::MarshallInterface()
{
HRESULT hr;
if(SUCCEEDED(hr = ::CreateStreamOnHGlobal(NULL, TRUE, &pstm)))
{
LARGE_INTEGER bZero = {0, 0};
pstm->Seek(bZero, STREAM_SEEK_SET, NULL);
if(SUCCEEDED(::CoMarshalInterface(pstm, IID_IWebBrowser2, m_spBrowser,
MSHCTX_INPROC, NULL, MSHLFLAGS_NORMAL)))
{
pstm->Seek(bZero, STREAM_SEEK_SET, NULL);
}
}
}
void CIECanvas::UnmarshallInterface()
{
LARGE_INTEGER bZero = {0, 0};
pstm->Seek(bZero, STREAM_SEEK_SET, NULL);
HRESULT hr = ::CoUnmarshalInterface(pstm, IID_IWebBrowser2,
(void**)&m_spBrowser);
if(FAILED(hr))
{
showMessageBox("CIECanvas::UnmarshallInterface()", "%s %ld", "FAILED.
ERROR CODE = ", GetLastError());
}
}
Then for recording I use AfxConnectionAdvise(), which is working fine.
The problem I am facing is in Replaying the events.
1)The VM crashes with a hotspot error, when on the first page some link
click event is present, which loads a new page. One observation here is the
VM crashes after onBeforeNavigate2 or TitleChange events are fired.
2)I also tried Yahoo's registration page (having a lot of dropdowns and
checkboxes), it works fine for the first few events, but then the VM
crashes.
My questions are
1)Does IE handle the events like page loading (tiltle change etc.) and click
on some link in different threads? How are the events handled (any useful
info on this)?
2)How should I fix the problem?
3)Is it related to marshalling of IE COM pointers?
Please replay ASAP,
Nikhil

- Static Variables and JAR FilesI am curious - does the scope of static variables carry across
different JAR files?
Here's the issue:
BaseClass is in "BaseClasses.jar"
ExtendedClassA extends BaseClass is in "AnotherPackage.jar"
ExtendedClassB extends BaseClass is in "EvenAnotherPackage.jar"
BaseClass has a static object (ObjectX). Now, normally, this static
object is static across all of the subclasses. However...
These JAR files (AnotherPackage and EvenAnotherPackage) are being read
in by a separate tool. When ExtendedClassA and ExtendedClassB are
used within the context of this tool, ObjectX is instantiated twice
and has two separate values. As far as I can tell, the tool runs
ExtendedClassA and ExtendedClassB within the same JVM, so I am unsure
of what is going on.
Does anybody have any insight into what is going on here? (Sorry for
being vague. I'm not actually working the project, but I'm curious
from an academic standpoint. Another group ran across this problem
today.)

- JNDI Authenticate UserHi All,
I have the below code which is supposed to return a true if the user is
authenticated against active directory and false if the user is not.
This works fine if you send it a correct username and correct password. It
also works if you send it a correct username with an incorrect password. It
also works if you send it an in-correct username with a password.
My problem is that a few accounts in the directory don't have passwords set.
I.e. password is blank. If I send any username without a password then it
always returns true, even if that user has a password set or the user
doesn't exist. Does anyone have any ideas why this is?
<code>
public boolean authenticateUser(String userName, String password){
//Try to log in with the supplied username and password
//If it fails then either the user doesn't exist or the wrong
crudentials where supplied
try{
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, ldapConnectionString);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, userName + "@" +
ADName);
env.put(Context.SECURITY_CREDENTIALS, password);
DirContext ctx = new InitialDirContext(env);
return true;
}catch(Exception ex){
//Authentication failed
return false;
}
}

java-programmer, JMS and https
Hi all,
Have JMS to use with https
It says in documentation to supply these four arguments,
javax.net.ssl.trustStore, javax.net.ssl.keyStore,
javax.net.ssl.keyStoreType and javax.net.ssl.keyStorePassword
Here's my sample below:
System.setProperty("javax.net.ssl.trustStore", "C:\\Program
Files\\Java\\j2re1.4.2_03\\lib\\security\\cacerts");
System.setProperty("javax.net.ssl.keyStore",
"D:\\Projects\\certificates\\tomcat.keystore");
System.setProperty("javax.net.ssl.keyStoreType", "jks");
System.setProperty("javax.net.ssl.keyStorePassword",
"changeit");
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"org.exolab.jms.jndi.InitialContextFactory");
properties.put(Context.PROVIDER_URL,
"https://localhost:8443/");
jndiContext = new InitialContext(properties);
For some reason after creating the new initial context, its reporting:
Default SSL context init failed: null
Did I set my trustStore path correctly?
Thanks

- How does Java make assignments atomic?>From what I understand, Java guarantees that all assignments to
primitive types (except non-volatile 64-bit types) will be atomic.
How does it do this? I thought that the only truly uninterruptable
processor instruction was the test-and-set, and that test-and-set was
the basis from which richer thread synchronization resources typically
provided by an underlying operating system (e.g. semaphores, mutexes,
critical sections) were built.
Does Java internally implement all of its generated assignment opcodes
inside some kind of test-and-set-based wrappers?
Thanks.

- corba-J2EE-EJB-WebSphere?Some help for a newbee?
I've been a c/C++ programmer in VMS, OS/400, and most recently, Windows
and Dot Net. However, I have recently signed on as Q/A manager at a
predominantly Java shop. We have some consultants coming in to assess our
scaleability and architecture, and I'd like to be in a position to at least
make some intelligable noises. I have gotten the sense that there is at
least some compatability between these, but I'm not picking up the extent,
if any, to which any are essentially competing technologies. Is some subset
of these an obvious choice for a medium volume site with lots of active
content, with scaleability, performance, and maintainability being our top
three criteria? Thanks.

Indeed. That's more of a symptom of a problem than a reasonable
solution. You're then left with a class that professes to follow an
interface, but doesn't follow it. What you really wanted was to
implement a different interface on top of existing functionality... a
task for which composition is ideal.
Of course, in a pinch, the exception-throwing kludge will work; it's
integrated into the collections API and even given a fancy name:
"optional methods". However, even its light application there is
generally acknowledged to be one of the few great failures of that API.

I'm referring to the informations displayed on this page:
http://www.vuxml.org/freebsd/18e5428f-ae7c-11d9-837d-000e0c2e438a.html
Is the information about linux-sun-jdk15 correct?
1.5.* <= linux-sun-jdk <= 1.5.2.02,2
I think that the correct version should be 1.5.0.02,2 considering also that a 1.5 based version >=1.5.1 doesn't (yet) exist.
The last jdk versions for linux is 1.5.0.11 and the port with that version has been committed today, but portaudit is still complaining about this vulnerability.
Thank you.
P.S.
Sorry if I'm writing to too many people, but I'm not sure about who is responsible for that problem.

I've experimented with using BigInteger instead of int in my code with
mixed results. Code that was integer-math intensive (e.g. finding prime
numbers) typically ran 5 to 7 times slower, which is pretty bad, but not
"noticeable" for typical user applications. I'll probably continue this
practice because for most of my apps, the bottleneck is not the
integer-math, and the extra flexibility is nice.
My question is: is there a "best" way to store BigInteger and BigDecimal
values in databases (particularly in SQL)? The two most obvious solutions to
me is to store them as BLOBs or as strings. I'd probably favor the latter,
because although it uses more storage space and processing time (e.g. to
parse the string back into a BigInteger value), it'll probably be easier to
inspect the DB to make sure all the values are correct during debugging.

You get the point. I do not want to have 3 queries, but only one that
returns something like described above.
For now I have a functioin that does this, but the algorithm is not
the best, and it only works for two levels (so XML without the s/n for
example).
This must be a common problem, I would appriciate input as to how this
is commonly done, any pointers to web sites, articles... are all
welcome. I'd try to search the groups but for what?:) I would also
like to describe my current algorithm, but for now it seems I would
just bore you.

examples I was able to build a listener that receives snmp traps. It's
working fine (when running through console).
So I decided to start it automatically, together with my web
application (that is running under tomcat).
I have a servlet that is executed when tomcat starts (using
<load-on-startup>). So I did a call to my new class.
The problem is that this class is actually a listener. When it starts,
it hangs the other procedures, including tomcat initilization.
I tryed to put it under a thread, but it also hangs as soon it starts
to listen for snmp traps.
How do I ran a listner without blocking other processes? I am looking
for a solution that should work both on linux and windows.
I don't know if I made myself understood. Sorry my poor english.
TIA,
Bob
