Problem installing WL 6.1SP3 on Linux - 'Exception in thread "main"'

I'm trying to install an evaluation copy of WEBLOGIC 6.1 SP3 in a Linux REDHAT
7.x. I did the following:
1. Instaled the JDK 1.3.1
2. Inserted the JDK1.3.1 as the first path in my $PATH
3. Called: java -cp weblogic610sp3_generic.zip install
And this message appears: Exception in thread "main"
Does any one can help me ?
Thanks in advance
Alvaro Pereira

I've found my problem. I've started X with a non-superuser user and I've openned
a terminal console, issued a 'su - root' and began the installation.
When I start X with root user, everythink goes fine.

Sorry to steal this thread but I'm new here and don't know yet how to open new thread. I'm getting this error too. I'm at the very start of a book titled "Teach Yourself Java" and I'm trying execute the first example. I downloaded and installed Java at
C:\Program Files\Java\jdk1.6.0_11\bin.
I set up folder C:\Java Applications and put my first fiel in there titeld Example1.java
Based an another thread here I went into Start | Control Panel | Ssystem | Advanced | Environment Variables and updated variable PATH by adding to the end of it ;C:\Program Files\Java\jdk1.6.0_11\bin.
I can now navigate to C:\Java Applications and exeute javac Example1.java and it compiles OK but when I execute java Example1.java I get the error Exception in thread "main" java.lang.NoClassDefFoundError.
I dont' know anything about the set CLASSPATH that is mentioned in this thread. Where does that go or is there something else I need?

Error in installing patch 9.0.1.4. "Exception in Thread "main"

Hi to all....
Want to ask a problem regarding installing patch Oracle database patch 9.0.1.4.
Previously, i got problems in installing other patch. The solution i got is to install the below patch.
They suggested that i have to install Patch 3038037.
and when I read the ReadMe of Patch 3038037, it stated
2 Preinstallation Requirements
The following list is the preinstallation requirements for this patch set:
Ensure that Oracle database patch 9.0.1.4 is applied to database instances
before applying the Oracle9iAS version 9.0.2.3 patch to infrastructure
instances.
So, in this case, i have to install "Oracle database patch 9.0.1.4" first
before i can install "Patch 3038037"
So, currently, i am trying to install the Oracle database patch 9.0.1.4...got error that are
1) Tried to run runInstaller in Disk1
./runInstaller: Command not found
2)The runInstaller in Disk1 actually will run runInstaller in folder "Disk1/install/solaris"..
but when i run it, it gaves me
"Exception in Thread "main" java.lang.NoClassDefFoundError:/ "
Have any ideas or experience?
Regards,
Rushdan.

try execute: export LD_ASSUME_KERNEL=2.4.1 before you run ./runInstaller
Btw try look at http://www.puschitz.com for installation guide.

How to solve this problem"exception in thread "main" java.lang.noclassdeff"

I am a tyro of java programming .
i downloaded the j2sdk-1_4_2_09-windows-i586-p.exe from www.java.sun.com and installed it at the defaulted path C:\j2sdk1.4.2_09,
then i wrote down my first java program as follow:
public class hello
public static void main (String args[])
System.out.println("hello,��!");
}and stored it at C:\Javasmp\ch01\hello.java.
after that i opened dos commind window and compiled it :
c:\javac C:\Javasmp\ch01\hello.java. and obtained file hello.class (C:\Javasmp\ch01\hello.class)
but when running it (c:\java C:\Javasmp\ch01\hello) there was a mistake:
exception in thread "main"java.lang.noclassdeffounderror:C:\Javasmp\ch01\hello
i searched on the internet and found out the solution is set enviroment viriable ,so i set the "CLASSPATH" as".;C:\j2sdk1.4.2_09\lib;C:\j2sdk1.4.2_09\lib\tools.jar" ,"PATH" as"C:\j2sdk1.4.2_09\bin;C:\Windows\system32;c:\windows\system32\Wbem" and "JAVA_HOME" as "C:\j2sdk1.4.2_09\bin;C:\j2sdk1.4.2_09\jre\bin"
afer that, i opened a new dos command window and run it again ,but the problem was still unsolved.
in addition,my os is "windows xp"
anyone can help me ,thank you!
i am a student in China,it's a hard time for me to write down my question in english ,i doubt whether i express my question clearly.

"Exception in thread "main" java.lang.UnsatisfiedLinkError:" JNI in Linux

Hi,
I am writing a simple program to understand how JNI works so that I can use this concept to develop a project. But after running the simple code,
It gives the following error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: sum
at TestJni.main(testJni.java:25)
My Java code is:
import java.io.*;
import java.util.*;
class TestJni
// Try to load the native Code library for user Authentication.
static
try
System.loadLibrary( "test" );
catch( UnsatisfiedLinkError e )
System.out.println("Could not load native code for user authentication." );
System.exit(1);
public static void main( String [] args )
//TestJni obj = new TestJni();
System.out.println(TestJni.sum(2, 3));
public static native int sum( int x, int y );
TestJni.h looks like:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class TestJni */
#ifndef IncludedTestJni
#define IncludedTestJni
#ifdef __cplusplus
extern "C" {
#endif
* Class: TestJni
* Method: sum
* Signature: (II)I
JNIEXPORT jint JNICALL Java_TestJni_sum
(JNIEnv *, jclass, jint, jint);
#ifdef __cplusplus
#endif
#endif
and my C++ code is:
#include <jni.h>
#include "TestJni.h"
#include <stdio.h>
JNIEXPORT jint JNICALL Java_TestJni_sum(JNIEnv *env, jclass obj, jint x, jint y)
printf("Inside the native function\n");
return (x + y);
Then I am generating my .so file as:
g++ -o libtest.so sum.cpp -shared -fpic -lcrypt -I//usr/lib/j2se/1.4/include -I/usr/lib/j2se/1.4/include/linux
and copying the libtest.so file into the folder where I have my TestJni.class file. Then running the java code by:
java TestJni
but it gives the "UnsatisfiedLinkError". What to do? :( I have spend 2 days now to solve this problem but I am not getting it.
I am using ubuntu 7.10 as my OS.
Please let me know if you can help.

Thanks for your response. I found that, when I copied the shared library to /usr/lib and
did: ldconfig -n /usr/lib it worked
But the problem is, this is my computer, but the computers that I am going to run my actual
JNI application, have restrictive permission. Could anyone please let me know how I can
do the work without ldconfig. I mean is there anyway I can configure my .so file's path without
copying it into the /usr/lib folder and without ldconfig?
I will appreciate any reply. Thanks.

Exception in thread "main" java.lang.NoClassDefFoundError: rep.jar in linux

Hi
I am new to java and am trying to deploy a code on linux red hat 4.I have 5 files namely:
1.ClassReportGenerator.java
2.ClassScheduler.java
3.manifest
4.rep_compile.sh
5.repgen.sh
first the rep_compile.sh is used to generate the class files for the two java files and then it creates a jar file
rep.jar file.
rep_compile.sh
export PATH=/app/oradshome/jdk/bin:/app/oradshome:$PATH
echo "Compiling ClassReportGenerator.java ClassScheduler.java"
javac -verbose ClassReportGenerator.java ClassScheduler.java
echo "Creating jar from manifest file"
jar -cvfm rep.jar manifest ClassReportGenerator.class ClassScheduler.class
echo "Executing repgen.sh"
sh repgen.sh
At the end it calls the repgen.sh file
which sets some path and class paths and then takes some user inputs and fires the command
paths being set---
export CLASSPATH=/dit/reports/rep.jar:$CLASSPATH
export PATH=/app/oradshome/jdk/bin:/app/oracle/OraHome/bin:$PATH
command being fired

Exception in thread "main" java.lang.Error: Unresolved compilation problem

The following code:

          //p.l(person);p.l(node.intData);
          if(node.intData.compareTo(person)==0)

          else
               return false;
     }returns the following compilation error:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:

     at MusbachJ_TreeNode.find(MusbachJ_TreeNode.java:32)

But I don't understand, the else statement is right there, what more does it want? Thanks! :)

Exception in thread "main" java.lang.Error: Unresolved compilation problem: Unresolved compilation problem is an error that you'll only ever see if you're using an IDE. If you used the javac compiler, then you would have seen that the code doesn't even compile.
The reason (as others have pointed out) is, that some paths through your method don't return a value.
I'll re-write your code in the code-style that I usually use, because then it might be easier for you to see the problem:
public boolean find(MusbachJ_Person person,BstNode node)
     if(node.intData.compareTo(person)==0) {
          return true;
     if( node.leftNode != null ) {
          find(person,node.leftNode );
     if( node.rightNode != null ) {
          find( person, node.rightNode);
     else {
          return false;
}There are two prolbems. I'll spell out the first and let the other one for you to find:
1.) you don't do anything with the return-values of the find-methods you are calling. What do you want to do with them?
2.) What do you return if the current node is not the one that you want and you've got a right node?

Exception in thread "main" java.lang.NoClassDefFoundError: Helloworld

Hi Java Experts,
I am at a lost to how Java searches for all the classes when running a program. Below are the following steps I have taken to try a simple basic HelloWorld.java program on the command prompt on Windows XP (SP2) platform:
( i ) Installed both jdk1.5.0_09 and Netbeans IDE 5.0 and working properly.
( ii ) The source file is located in F:\Documents and Settings\abc\HeadFirstDesignPattern\src\ch11 and the compiled file is in F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes\ch11 which was compiled in Netbeans.
( iii ) No problem compiling & running this program in Netbeans.
( iv ) The RUN CLASSPATH in Netbeans is F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes.
( v ) No CLASSPATH variable has been set.
( vi ) The HelloWorld program looks like this:
package ch11;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
( vi ) Got the message
"Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld"
when running a combination of the following Java commands:
( a ) cd F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes
( b ) java HelloWorld, or
java -cp . HelloWorld or java -cp "." HelloWorld, or
java -cp F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes" HelloWorld, or
java -cp F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes;. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld, or
java -cp "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";"." HelloWorld, or
java -cp "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";"." ch11\HelloWorld.
It is the package location which is a subdirectory of F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes which caused Java not to find this program. I had no problem running it if the HelloWorld.java was moved one level up. ie from F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes\ch11 to F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes.
I have written Java in the last year mostly on Netbeans without any problem running them.
The reason for having to learn to run Java on the command line is so that I could add arguments to the program which I couldn't do in Netbeans just yet.
I have gone through a lot of the articles from Java forums, Google searches but yet to have found a solution.
Many thanks,
Netbeans Fan

I am getting the same problem when running the same program on a Fedora 4.0 (Redhat Linux 10) system, together with Netbeans 5.5 and JDK1.5.0_09. Again, I have no such problem when running the same program in Netbeans.
Here are the steps that I have taken as follows:

Exception in thread "main" java.lang.InternalError: Can't connect to X11 wi

Hello Friends,
I dont know whether this would be the correct forum or not but my problem is very critical so please help me.
1. I am working on linux server where I have installed Tomcat4.x, Apache 2.0, JDK1.4.2. I have set all CLASSPATH.
Java is working fine. I am using one JCLASS component which is useful in chart creation.
3. Few days back the code regarding Frame cration was working fine but now its giving an error. I am actually running these files using cron and my requirement is also same.
4. I have tried almost all possibilities like
export DISPLAY=localhost:0.0
export DISPLAY=ipaddress:0.0, but no luck.
Can you explain me what could be the reason.

You are probably creating images on the fly.
Due to a bug/annoyance in the JDK, it requires an X-display. This is not related to the Sun ONE Webserver but a general problem.
-Either install an X server, but this might not be possible because of a server security strip.
-install a virtual X xvfb or something alike to emulate this behaviour.
I thought it would be solved in newer JDK's but in which i'm not sure.

HELP Needed with this error: Exception in thread "main" java.lang.NoClass

Folks,
I am having a problem connecting to my MSDE SQL 2000 DB on a WindowsXP pro. environment. I am learning Java and writing a small test prgm to connect the the database. The code compiles ok, but when I try to execute it i keep getting this error:
"Exception in thread "main" java.lang.NoClassDefFoundError: Test1"
I am using the Microsoft jdbc driver and my CLASSPATH is setup correctly, I've also noticed that several people have complained about this error, but have not seen any solutions....can someone help ?
Here is the one of the test programs that I am using:
import java.sql.*;
* Microsoft SQL Server JDBC test program
public class Test1 {
public Test1() throws Exception {
// Get connection
DriverManager.registerDriver(new
com.microsoft.jdbc.sqlserver.SQLServerDriver());
Connection connection = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://LAPTOP01:1433","sa","sqladmin");
if (connection != null) {
System.out.println();
System.out.println("Successfully connected");
System.out.println();
// Meta data
DatabaseMetaData meta = connection.getMetaData();
System.out.println("\nDriver Information");
System.out.println("Driver Name: "
+ meta.getDriverName());
System.out.println("Driver Version: "
+ meta.getDriverVersion());
System.out.println("\nDatabase Information ");
System.out.println("Database Name: "
+ meta.getDatabaseProductName());
System.out.println("Database Version: "+
meta.getDatabaseProductVersion());
} // Test
public static void main (String args[]) throws Exception {
Test1 test = new Test1();

I want to say that there was nothing wrong
with my classpath config., I am still not sure why
that didn't work, there is what I did to resolved
this issue.You can say that all you like but if you are getting NoClassDefFound errors, that's because the class associated with the error is not in your classpath.
(For future reference: you will find it easier to solve problems if you assume that the problem is your fault, instead of trying to blame something else. It almost always is your fault -- at least that's been my experience.)
1. I had to set my DB connection protocol to TCP/IP
(this was not the default), this was done by running
the
file "svrnetcn.exe" and then in the SQL Server Network
Utility window, enable TCP/IP and set the port to
1433.Irrelevant to the classpath problem.
2. I then copied all three of the Microsoft JDBC
driver files to the ..\jre\lib\ext dir of my jdk
installed dir.The classpath always includes all jar files in this directory. That's why doing that fixed your problem. My bet is that you didn't have the jar file containing the driver in your classpath before, you just had the directory containing that jar file.
3. Updated my OS path to located these files
and....BINGO! (that simple)Unnecessary for solving classpath problems.
4. Took a crash course on JDBC & basic Java and now I
have created my database, all tables, scripts,
stored procedures and can read/write and do all kinds
of neat stuff.All's well that ends well. After a few months you'll wonder what all the fuss was about.

Exception in thread "main" dbca OEL 4.7

Hallo!I am a newbie in Oracle 10g having installed Oracle 10g in Oracle Enterprise Linux version 4 update 7.
While installing Oracle 10g (I installed it on my Laptop the server and not remotely),I configured xhost + display parameters via the commands below
[root@joey-oel ~]# xhost +
access control disabled, clients can connect from any host
[root@joey-oel ~]# su - oracle
[oracle@joey-oel ~]$ DISPLAY=10.0.0.1:0.0
[oracle@joey-oel ~]$ export DISPLAY
IP address 10.0.0.1 is the IP address of the server from where I am installing Oracle.When I try to launch the DBCA via the command below,
[oracle@joey-oel ~]$ dbca
I get the following error
Exception in thread "main" [oracle@joey-oel ~]$ dbca
Thus,I tried to reconfigure the display parameters as below but the errors shown below appear
[root@joey-oel ~]# xhost +
xhost: unable to open display "10.0.0.1:0.0"
[root@joey-oel ~]# su - oracle
[oracle@joey-oel ~]$ DISPLAY=10.0.0.1:0.0
[oracle@joey-oel ~]$ export DISPLAY
[oracle@joey-oel ~]$ xhost +
xhost: unable to open display "10.0.0.1:0.0"
[oracle@joey-oel ~]$ dbca
Exception in thread "main" [oracle@joey-oel ~]$
How do I resolve this?
Thanks.

What happens when you close the terminal , open a new terminal , issue as Root user xhost+ and then fire up dbca in Oralce user? Don't set again the display variable in the Oracle user if you have given xhost+ as Root.
HTH
Aman....
