- Struts and AA based on a database
Hello:)
I have a question concerning authentification/authorization and
elements visibility on a Web page in Struts. How to manage the
visibility of control elements in a Struts-based application? The
information about users should be stored in a database and not in XML
configuration files. How to use role based or/and function based
authorization system and how to retrieve the rights from a database and
store them in the Principal object? The application is mantained within
Tomcat application server. So, how to do this? Or, being more precise,
is there any open-source library which provides such a functionality or
should I develop everything from scratch? Do you have some examples for
such stuff?
best regards,
Ania

- Eclipse vs NetBeans vs Jbuilder under LinuxHello everyone,
I've tried the above 3 IDEs in the last year and thought I might make some
comments and ask for your thoughts. Just for interest sake and please don't
start a Holy War ;-)
I originally used netBeans for development, but switched over to Jbuilder
because we where doing tomcat/struts development and my boss said it had
better support. I didn't really get to use netBeans struts stuff but it did
seem a bit weak in comparision.
I would have thought Borland would have a great editor, but I find it very
buggy in comparison to netBeans. Some of the things I have had problems
with include the cursor not being moved when you click in the text area
(this tends to screw up click and drag rearrangement of text or do it when
you don't mean too), auto-formatting of code rearranging it until it won't
compile, method parameter popups not always accessable, method parameter
popups not able to show the names of parameters - only the type, and some
others I can't remember right now.
However, the struts support in JBuilder does seem to be better than netBeans
and runs quite well. Over all the IDE also seems a little quicker and I
quite like the way that you can have multiple projects open and flip
between then with ease. netBeans doesn't seem to handle multiple projects
as smoothly as JBuilder.
I also tried Eclipse at home a couple of time in the last 6 months and at
the moment I can't see why many people are using it. On both occasions I
found also sorts of nasty bugs which tended to simple drive me nuts. The
last time time I used it for example, I found that it would not run the
code I had just edited. I.e. if I could load a project, made some changes
and hit the run button, it would run the code without the changes included.
In order to get the changes it, I had to explicitly do a save before each
run. This sounds trivial but can get very annoying, both netBeans and
JBuilder run the code you are editing, not the last saved code.
Eclipse also seemed to have a strange concept of projects. It looked rather
good with being able to see multiple project trees at the same time until
it came to running them. Then it appeared to separate the concept of
running a projects from the projects themselves and I had to effectively
re-setup again. I also found that if I had en error in one project, it
would fail the compile even if I was in another project. So whilst I could
have multiple projects open at a single time, it seemed to have trouble
understanding which projects I was in and what it was to compile. This
resulted in me having to unload/reload projects on a regular basis. I also
remember not being that happy with it's editor either, I can't remember
exactly why right now.
So, I would have to say that at the moment, I would tend to use netBeans for
general development, JBuilder for struts and Eclipse not at all.

- Communicating with a servlet using NIO?Is it possible for a client applet to communicate with a servlet using NIO?
I know it's possible using standard IO but I would like to implement a
servlet that accepts NIO connections from clients and interacts with them.
Is this possible? I don't want to use a special port because of firewall
considerations.

There's nothing which "requires" you to forward to a JSP; you could
just as easily forward to an action. The hitch here is that the
ActionForm will be populated according to the request parameters if
you just perform a forward. The solution is simply to specify
redirect="true" in the forwarding action so that the request
parameters get lost.
Just be careful in your validate method when using this mechanism:
you're users will be irked if the first time they see a page it
contains all manner of error messages. Since you often provide a
reset button on a form, the smart way to approach the situation is
to hold off generating errors if all form fields are blank (or
have the default value).
If this doesn't make perfect sense then repost and I'll dig up
some sample code. Or contact me off-line.

- Java GSM encoding from micHi
I'm trying to encode a microphone stream into GSM using
org.tritonus.lowlevel.gsm.Encoder but I am receiving just static noise -
I've checked the raw PCM output and it's fine. Is there anything obvious
that's missing here?
Thanks
__________________________
The mic is opened as:
AudioInputStream ais=null;
DataLine.Info info_mic = new DataLine.Info(TargetDataLine.class,
new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 8000.0f, 16, 1, 2,
8000.0f, false)
);
TargetDataLine mic = (TargetDataLine) AudioSystem.getLine(info_mic);
mic.open();
mic.start();
ais = new AudioInputStream(mic);
_____________________
And the GSM frame encoder is:
/*------*/
byte [] gsmframe(AudioInputStream ais){
byte [] encd = new byte[33];
try{
byte [] b = new byte[320];
ais.read(b,0,b.length);
DataInputStream di = new DataInputStream(new ByteArrayInputStream(b));
short [] buf = new short[160];
short j=0;
for(int k=0; k<buf.length; k++){
j=di.readShort();
buf[k]=j;
}
org.tritonus.lowlevel.gsm.Encoder enc = new
org.tritonus.lowlevel.gsm.Encoder();
enc.encode(buf, encd);
}catch(Exception e){
System.out.println("error with microphone reading "+e);
return null;
}
return encd;
}

- Jars built with JDK 1.3 and JDK 1.4 interoperatingThe Runtime Environment is JRE 1.4. The latest code I have written has
been compiled with JDK 1.4. However it depends on some packages written
and compiled with JDK 1.3. Is there anything to look out for in this
kind of setup or should I have to recompile the older code with 1.4? I
have tested the whole thing and it works, but I wanted some more
information. It is a swing code and I need the JProgressBar's
indeterminate state which is available only in JDK 1.4.
Any update is welcome. If there is any document explaining the above,
that would be perfect. I searched but I was not able to find any
reference.

- Forcing System.gc()I have an app that, at one point, really bogs down as so many objects are
created and released in a lengthy process.
I am wondering if I may not be able to improve performance by System.gc() in
some "right" places in my code (wherever those might be!). It seems to me
though, that the gc facilities in Java are so good, that this is something
best left up to the JVM, and NOT mess with putting System.gc() in anyplace?
I am on WinXP / Vista and JRE 1.6.x. TIA, R. Vince

- C++ programmer stumbles over pass by value. Need advice.Here's a model of my problem. I see what's causing it (thinking in C++,
with pass by reference) but I don't see a Java way to solve it. Probably
because I'm so new to Java.
Here's the problem.
2 methods inside the same class. Method1 passes a String array to
method2, relying on method2 to process the string array and return a
String and a new String array for further processing back to method1.
public boolean method1 (String s1, other args)
{
//do some stuff
String [] sa1 = null; // to be created and returned by method2
String s2 = null; // to be created and returned by method2
Method2(s1, sa1, s2)l
//do some important stuff with sa1 and s2
return true;
}
// C++ type method (unfortunately)
private void method2 (String s1, String [] sa1, String s2)
{
//do some stuff
StringTokenizer st = new StringTokenizer(s1, "/");
String sRemainder;
sRemainder = st.nextToken();
s2 = st.nextToken(); // just a string to be returned
sa1 = sRemainder.split(","); // a string array to be returned
}
The eclipse debugger confirms that method 2 is processing the strings
exactly as I want it to. sa1 and s2 after the processing look great
inside method 2. But they're null after the return to method1. I assume
this is because sa1 and s2 are copies inside method 2 and they go out of
scope on the return. sa2 and s1 are created inside method2 but I need
them for further work in method 1.
I obviously coded this like a C/C++ programmer. What I'd like to know is
what's the conventional methodology (or programming idiom) for passing
back lots of stuff created in one method to it's caller? Feel free to
hack up the above example to show me how, if it's convenient.
Thanks in advance for your help/

- Corba java apllet client communication problemI hava a problem with communication between Java/Corba server based on JDK
ORB with Java/Corba client (applet)

I sure could use the help. The instructions in help don't really explain

What do I do??

- Tomcat, Oracle, connection pooling, BLOBsI have a rather strange problem with Tomcat's connection pooling and
the Oracle JDBC driver when using BLOBs that seems to be related to
class loading.
My configuration:
Tomcat 5.0.27
Oracle 9i
ojdbc14.jar is in $CATALINA_HOME/common/lib (and nowhere else)
The datasource is configured in server.xml
Everything works perfectly as long as I don't configure the datasource
in the server.xml file (including reading/writing BLOBs).
Once I use the datasource configuration in server.xml everything
except Oracle's BLOB implementation works (means: I can access the
tables, insert, select etc., but I can't read/write BLOBs)).
The problem is with class loading:
System.out.println(getConnection() instanceof
oracle.jdbc.driver.OracleConnection);
System.out.println(getConnection().getClass().getName());
results in:
false
oracle.jdbc.driver.OracleConnection
So the connection is of the expected type, but the type has been
loaded with the wrong class loader. This leads to a ClassCastException
in the Oracle JDBC driver (createTemporary()).
As I told you the JDBC driver is in common/lib and nowhere else, so
the class should be available in the application code.
Any hints ?

- Validating parsed XML document against XML-schema*PROBLEM: how to validate parsed XML document against (parsed) XML-schema.
*IN: XML document as org.w3c.dom.Document, XML-schema as stream
*OUT: information if document is valid against schema. If document is not
valid DETAILED information about ALL errors (especially: node that caused
problem).
*Additional information:
- validation is performed quite often,
- XML-document object is changed quite often,
- XML-Schema is fixed.
- XML-document doesn't contain information about related XML-schema
(attr xsi:noNamespaceSchemaLocation)
- XML-Schema is available as file only when the application starts.
It means that schema can be loaded from a file only once.
- must works in Java1.4+
I've tried to implement it using JAXP:
//app start
SchemaFactory schemaFactory =
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Source schemaSource = new StreamSource(new File(schemaFile));
Schema schema = schemaFactory.newSchema(schemaSource);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(xmlFile);
//document is being changed usign .addChild etc.
//
Validator validator = schema.newValidator();
validator.setErrorHandler(new SimpleErrorHandler());
validator.validate(new DOMSource(document));
Unfortunately org.xml.sax.ErrorHandler gets only SAXParseException which
doesn't constant information about node that caused the problem.
Is there any other way to validated DOM-document?

Because the source code and build infrastructure aren't included for either
the JAR or the native library in the source that Sun distributes(*). You
could copy the included Linux/Solaris JARs over, but then you need to build
the corresponding native library somehow.
* - Actually, the source is there, but its bundled up and there is no
build infrastructure.
Thats my recollection at least.

- Vendor independent data sourceI have an application that I deployed to WebSphere using the default
Struts datasource from it's action. I've been reading about this now
and it sounds like this is not the prefered way to make a database
connection pool. They suggest using the containers, but I want to
remain vendor independent and be able to deploy my application in any
container with little or no changes.
I know there must be a standard non-vendor specific way to create a
connection pool. Can someone tell me what that standard is? Searching
the web just provided me with about 100 different ways to do it, but I
want the "Java Standard" way to do this.

- Java inherited annotationsHello all!
Some times ago the problem was raised... I and my collegs started to
use Java annotations and noticed that our annotations those was made
for java interfaces and their methods didn't accessible in inherited
classes and interfaces... I tried to use the metatag @Inherited but IMHO
it doesn't work correctly. Anyway we have made our own realization of
inherited Java annotations and shared it. So u can use it if you want.
It is free and open source. Can be downloaded from here:
http://www.fusionsoft-online.com/annotation.php
Best Regards,
Michael Milonov
