SUN C++ 4.2 could not find POSIX thread on Solaris 2.6
I am trying to compile JTC(JThreads)1.0.13 on Sun solaris 2.6.
I am able to compile JTC using gcc 2.95 but when i am compiling same application with Sun C++ 4.2 it is not able to find out POSIX threads , thus giving error
Operating system doesn't support threads.
I have tried compiling the same application on Sun Solaris 2.7 with C++ 4.2 , where it goes fine
I have got pthread.h.
Please help
C++ 4.2 is not supported on Solaris 2.6. Sun 5.X is.

2 Do we have any workaround for this issue?
3 When will the final 12.4 release be available?I can't say for sure whether your problem is fixed in the final release without a test case, but I'd say the chances are very good.
The final release will be announced soon. Watch this space, or the Oracle Solaris Studio page for an announcement. -
Hi,
Im trying to create a Rest WS with a @GET method that will return me an Emp object. I need the output as a JSON string.

Could not find a valid Java virtual machine to load
On a fresh copy of CFMX8, when I run updater 7, it responds
'Could not find a valid Java virtual machine to load'.
This is being installed on a Win2K3 server and this is on a
'freshly minted' POC box solely for the purpose of
installing/testing CFMX8 to determine how it compares to our
CFMX6.1 environment.
You will notice that it is NOT being installed in the default
directory:

I do find it curious that I can run the Updater 6, and it
seems to behave properly (it finds the VM). I ran it just as a
test, then wiped everything to start over from scratch. For some
reason do I need to direct Updater 7 to the installation that I did
not have to do in Updater 6?

Hi,
I have installed Oracle11g_win64_11gR1, Database and Client.
The issue is unable to invoke "sqldeveloper", getting the following error message. Could you please help ?
FYI. I have already downloaded and installed installed JRE and JDK.
ie. C:\Program Files (x86)\Java\jre6\ and C:\Program Files\Java\jdk1.6.0_24, still did not work.

Let me know, if you need more information. Here is the error message.
Error Message
=========
(1) if I invoke sqldeveloper, directly from the location " C:\app\oracle\product\11.1.0\db_1\sqldeveloper\sqldeveloper\bin " using explorer, I do get error message

(2) if I invoke sqldeveloper, directly from the locationC:\app\oracle\product\11.1.0\client_1\sqldeveloper, it prompts me to enter "full path for java.exe".
When I enter full path and continue, still it continue to prompt and ask the same input.

Edited by: sivapara on Feb 16, 2011 1:08 PMI was able to resolve this issue by performing following.
1. Go to the location where sqldeveloperW.exe is being executed from.
2. You will find a file sqldeveloper.conf in that location. Edit this file and change the value of IncludeConfFile to point to actual place. For me following were old and new values.
OLD (Wrong) : IncludeConfFile ../../jdev/bin/ide.conf
NEW (Correct) : IncludeConfFile ../../ide/bin/ide.conf
After making above change in the sqldeveloper.conf file. Save and close it. Restart SQLDeveloper. You will not get the error anymore.
Thanks

Could not find main class. Program will now exit. *SIGH*.....
At first I thought it was just my own programs that I created with netbeans that had this problem; however, even the demo programs under the sdk folder give me this problem when i try to run them. Virtual Machine Loader will just come up with pop up saying "Could not find the main class. Program will not exit"
I am a fairly competent programmer, not new to java. But I am new to guis in java, and using netbeans to create them. The program I am creating gives me this error with javaw and with java it will tell me NoClassDef for grouplayout. I checked the manifest file it looks alright:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 10.0-b19 (Sun Microsystems Inc.)
Main-Class: desktopapplication2.DesktopApplication2
Class-Path: lib/appframework-1.0.3.jar lib/swing-worker-1.1.jar lib/swing-layout-1.0.1.jar lib/ant-swing.jar lib/SwingSet2.jar lib/swing-layout-1.0.3.jar
X-COMMENT: Main-Class will be added automatically by build
}(brackets not included)
I am sort of lost.... Do I need to install ant separately?
I feel like there may be some classpath issues?
I have java 1.6 update 4 and netbeans 6.0
I am completely lost I have been working on fixing this for the past 2 or 3 days now, and reading up all the information.
Note: This is just a standard desktop application.
Also I just thought of something. If I have install the development kit do I also need to install the framework or whatever for 6.0 separately? Meaning installing the latest version of jvm. Sorry if this isn't clear i forgot what it is called.
Sorry if this sounds like a beginner question or something, but I am going crazy. If i am having this much trouble running my own program i really hope distributing files won't be this much of a nightmare....Please become familar with resources at the NetBeans site. There are tutorials and FAQs that cover usage of NB, and how to do things like you're asking.
See my reply in this thread for more information

Could not find Factory: javax.faces.context.FacesContextFactory
I'm trying to start a new JSF with facelets app from scratch using JSF 1.2.06 on Tomcat 6.0.10 but I can't even get the app to start.
I get this when I try to start the app:
java.lang.IllegalStateException: Application was not properly initialized at startup, could not find Factory: javax.faces.context.FacesContextFactory

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
I've seen a few contradictory pieces of advice on how to resolve but none seem very promising.
What are the basic requirements for a JSF 1.2 application, especially regarding entries required in web.xml and faces-config.xml? I don't see this clearly documented anywhere on Sun's JSF site.
Thanks!I think I found the reason for this problem.
I should have also mentioned that my app contained a welcome page (index.jsp) that contained only a forward to my Facelet-based home page via:
<jsp:forward page="pages/stm/StmHome.jsf" />
My home page was named: StmHome.xhtml
I mapped the FacesServlet to handle all requests with a *.jsf extension
But I set the javax.faces.DEFAULT_SUFFIX context parameter to: .xhtml
When I changed the value for the forward tag in the index.jsp to "StmHome.xhtml" the app started ok and the home page displayed without error.
So it looks like this problem was caused by a mismatch between the value I set for the javax.faces.DEFAULT_SUFFIX context parameter and the value I set for the URL pattern in the FacesServlet mapping, correct ?
Which brings me to my next question: should the values for the javax.faces.DEFAULT_SUFFIX and the FacesServlet URL pattern always match?
Thanks! -
Could not find agent library on the library path or in the local directory
Hi all,
I'm trying to write a jvmti agent that write any information in a mysql db. I've written a simple agent that work correctly and now I'll try to insert the mysqlpp library in my agent:
1) I've added #include <mysql++.h>

It will not load otherwise, and you must specify -agentlib:x (rather than saying libx.so). Yes, it is "funny" how it gives the same uninformative error message for a wide variety of errors. It will also give you this same error message if there are still unresolved symbols upon loading your library (which would be my second guess).

Jar file could not find main class.. I cant see why?
I have read loads of tutorials on this and it should be very straight forward but i STILL cant make a working jar file of my program.. please see if you can see anything wrong with what im doing..
my program is one .java file that compiles perfectly, and is runnable both through eclipse and by using the command prompt.. i made a jar file using both eclipse and the command prompt, and neither worked.. every time i run it by double clicking it i get the error "could not find main class, program will exit". here is the contents of my jar:
CorePackage\IPEmailer.class
CorePackage\IPEmailer$1.class
CorePackage\IPEmailer$SMTPAuthenticator.class
META-INF\MANIFEST.MF
the MANIFEST.MF file contains:
Manifest-Version: 1.0
Class-path: .
Created-By: 1.6.0_02 (Sun Microsystems Inc.)
Main-Class: CorePackage.IPEmailer
(yes there is a blank line at the end)
the class mentioned in 'Main-Class' has a main method that looks like this:
public static void main(String[] args) {
// TODO Auto-generated method stub
new IPEmailer();
}the program uses 2 external jar files:
activation.jar
mail.jar
and reads a file called:
ipemailer.ini
and writes a file called:
ip.txt
the program has no GUI and is intended to run 'silently' in the background
please help me understand what is wrong with thispackage CorePackage;
import javax.mail.*;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import javax.mail.internet.*;
import java.util.*;
import java.io.*;
import java.net.*;
public class IPEmailer implements Runnable{
* @param args
String recipientsinput[]={""};
String subject;
String body;
String server;
String user;
String pass;
String from;
String urlString = "http://www.whatismyip.org";

long oldInterval;
Thread t = new Thread(this);
public static void main(String[] args) {
// TODO Auto-generated method stub
new IPEmailer();
public IPEmailer(){
..........etccould the problem be that the class is a thread? i cant see why it would be, but ive never made a jar where the main class also 'implements runnable' -

Where is SearchExcel.class?Excellent question, though I think I spotted a problem with the cp supplied.
Note the documentation for -cp state (in part)
For example, if directory foo contains a.jar and b.JAR, then the class path element foo/* is expanded to a A.jar:b.JAR, except that the order of jar files is unspecified.So instead of this..
java -cp /tmp/MyJava/excelapi:/app/jdk/1.6.0_16/jre/lib:/app/jdk/1.6.0_16/lib SearchExcel..try this..
java -cp /tmp/MyJava/excelapi/*:/app/jdk/1.6.0_16/jre/lib:/app/jdk/1.6.0_16/lib SearchExcelNotes:
1) Adding the JRE classes to the classpath should not be necessary, but I left the rest of the cp unaltered to highlight the one specific difference I am suggesting.
2) When posting code, code snippets, HTML/XML or input/output, please use the code tags. The code tags help retain the indentation and formatting of the sample. To use them, select the sample text and click the CODE button.
If that still fails, tell us more specifically where the SearchExcel class is by copy/pasting the output (within code tags) of the command..
prompt>jar -tvf mysearchexcel.jarWhere, of course, you replace 'mysearchexcel.jar' with the actual Jar name it is supposed to be located in.
Edit 1:
Changed JavaDocs -> documentation.

after that i wrote a program

class HelloWorldApp {
public static void main(String[] args) {
System.out.println("Hello World!"); // Display the string.
i saved in c:\ mywork
i compiled it with
javac HelloWorldApp.java and then
java HelloWorldApp
output / result also came
but iam unable to create jar file . when it is created it is showing
could not find the main class : HelloWorldApp program will exit
i created jar file by following way
i created

You have to specify the manifest with a special option (I think its was -M)
Otherwise the jar will create one (even if you provide it)No, the text file passed as a parameter will be incorporated in the manifest file generated by the JAR tool.
@OP: This will work:
JarTest.java
public class JarTest {
public static void main(String[] args) {
System.out.println("JarTest works!");
}manifest.txt
Main-Class: JarTest+(note there is an extra new line in the manifest.txt!)+
Now execute these commands:
javac JarTest.java
jar cfm MyJar.jar manifest.txt JarTest.class
java -jar MyJar.jar And on my machine, the string "JarTest works!" is displayed on the screen.
And if you look in the MANIFEST.MF file inside your jar file (you can use almost any zip-utility for this), you will see the following:

Any Ideas? I did a search on google, and looks like others have had this problem but found no answer.
US101There could be several reasons for getting this "Could not find main class" error message. From your stack trace it looks like the class javax/media/ControllerListener is not in your class path. Make sure your manifest file has a line like this:
Class-Path: pathToTheJarFileWithControllerListenerClass.jar otherJars.jar
This error message is also generated whenever any static initialization errors out giving the misleading error message implying that there is something wrong with the main class. Prior to starting your main class, static initialization of any static variables takes place. In my case, I was initializing a resource bundle, and forgot to include the property file in my building of the jar file. Well this failed of course and the generic error message appeared. It took many long hours to figure out it didn't have anything to do with the manifest file or the main class itself.

Could not find the main class: projectRFID.ProjectGUI. Program will exit.
Hello,
I'm quite new in Java. I have an application with GUI. When I'm using Eclipse version 3.4.0 to run the application, all it is working perfect.
But after I generate the jar from Eclipse, using the manifest file option from there and added the ProjectGUI to it, where is the main class, and try to run from the command line I receive the next error:
root@slax:~/workspace# java -jar rfid.jar

I run this application on a SLAX system with jdk6 update 7.
I tried to generate the jar file even from the command line using the manifest file option but I still receive the same error.
I hope somebody can help me!

The structure of my project in Eclipse is src/project/files.java and in jar file is src/files.java bin/class.java Dati/ and META-INF/.That's wrong. You don't need the .java files in the jar (but you can have them, if you want, they are just not used by Java).
And each .class file must be in a directory that reflects its package. So in your example ProjectGUI.class must be in the directory projectRFID/ inside the .jar file. -
Could not find the main class - Problem with Webservice-Access
Hello Everybody,
I'm having serious Problems with accessing a WebService (Tomcat-Axis) per executable jar-File.
I constructed a simple GUI with 3 Textboxes 1 Button and 1 Resultbox.
I use eclipse so it was no Problem to simple generate the Backgroundclient by Processing the .wsdl-File of the WS.
Now I do this:
Head_tServiceLocator serviceLocator = new Head_tServiceLocator();
Head_t service = serviceLocator.getRPCCall();
RPCCallSoapBindingStub Head_t = (RPCCallSoapBindingStub) service;and use the Webservice like an Object.
All this works very well.
Now the Problem:
Head_t service = serviceLocator.getRPCCall();this Line has to throw a ServiceException.
If i add a try-catch Block to Process the Message JAVA tells me after i exported to JAR (with Manifest-stuff and so on) and double Click on the JAR the following :
Could not find the main Class - Program will exit.
And if i add a throws Declaration to the Methodheader it tells me:
Fatal Exception Occured - Program will exit
But if i Comment out that Line at least the GUI is being displayed (so it DOES find the main-Class). But then of course the Webservice won't be accessed.
All the JARs needed (axis.jar, commons-discovery.jar and so on) are in the same Directory as the Webservice-Client.jar
Please Help me.
Greets,
ZapI am not done any typing mistake while creating the jar file i already followed the suggestion that you have mentioned but still the same error .
This is my MANIFEST.MF file created under META-INF folder
