Java.lang.NoClassDefFound Error while invoking dbua(9.2.0.8)on Sun Solaris.

Hi Friends,
I had installed Oracle 9.2.0.1(software alone) on Sun solaris box and then i installed the patchset 9.2.0.8 on the same Oracle 9i Home.It's installed.
But when i try to run dbca to cretae a database from $ORACLE_HOME/bin it throws the error:
java.lang.NoClassDefFoundError
i had set the PATH,ORACLE_SID,ORACLE_HOME,LD_LIBRARY_PATH but still getting the error.
Please suggest a fix.
Regrads,
Arun

Do you have JAVA_HOME set in your environment?
What's the result of
env
Make sure DBCA is calling the java under $ORACLE_HOME not from other installation.

Data Warehouse:java.lang.NoClassDefFound Error while using OWB API for Java

I was writing code to use the OWB APIs for Java:
I have imported the folowing files:
oracle.owb.connection.RepositoryManager;
oracle.owb.connection.OWBConnection;
oracle.owb.connection.ConnectionFailureException;
when jvm tries to get instance of Repositary Manger by the following code
reposManager = RepositoryManager.getInstance();
I get the following exception:
Exception in thread main
java.lang.NoClassDefFoundError: com/objectspace/jgl/HashMap
I have checked my OWB and Java environment but I cant locate com/objectspace/jgl.jar file. Can some one tell me were this jar is located in so i can import it.

Either use some criteria you develop related to one of the keys on the table or use some sort of record limiting method.
Note the method of limiting will vary related to the database you are using. You will have to look at the documentation.
For example I am told this will work in MySQL to get 200 records starting at record 100.
SELECT * FROM myTable ORDER BY whatever ASC LIMIT 100,200
Because you are running out of memroy I assume the table is large,
I am not sure what the impact of the above will have on performance because if in the above if the order by is not based on an index at the server level all the records will be selected and sorted before the records are limited.
I would make sure you have an appropriate index.
If you use the advanced search over the user forums using "resultset paging" and possibility the database you are using you should be able to get some ideas.
I hope this makes sense to you.

Could not find the main class. & java.lang.NoClassDefFound error:

sir / madam
I am facing problems with j2ksdk1.4.0 beta instalation on my windows 2000 advance server.
while installing pops up a message saying could not find the main class.
while using java or javac it says
Exception in thread main
java.lang.NoClassDefFound error:
com/sun/tools/javac/main
even when double clicking java plugin from the control panel
I get the Java virtual machine launcher saying could not find the main class.
I don't have any other java sdk installed.
And i have my environment variables (classpath, path and java_home) set correctly.
this same j2sdk1.4.0 version is installed in the windows 98 system and it's working fine.
Kindly do help me to solve this problem.
eagerly awaiting for your response.
Thanking you
Sajeev Nair
[email protected]

you must check with the classpath
please see that you have not repeated %classpath%
at the end of the class path like you do in win98.
similiarly with %path%
in win2000 it is automatically taken care off.

Java.lang.RuntimeException: Error while creating embedded frame

hello,
i know about http://forums.sun.com/thread.jspa?messageID=10273756, but this doens't helped.
i got a
java.lang.RuntimeException: Error while creating embedded frame
at sun.plugin.viewer.WNetscapePluginObject.createFrame(Unknown Source)
at sun.plugin.viewer.WNetscapePluginObject.setWindow(Unknown Source)
when starting a complex Java Applet in Firefox (2 + 3). Then the bowser freezes.
Internet Explorer freezes too, but doesn't left anything in the console.
Simple applets like http://www.java.com/en/download/help/testvm.xml works fine, but i doesn't know the special thing on my applet that keeps it from running.
The best thing about it is ... this happens only on some computers, on most systems the applet works as aspected.
i have no idea, where i should start to search to solve this problem, does anybody have one?
Systems that doesn't work : Win XP; Java Plugin 1.6.0_06
Systems that work : Win XP; all Java Plugins

I solved this problem by correcting a typo in the HTML source:
I had a error within the DIV tag containing the applet. In this case a TD tag within this DIV contained some bad characters. Such problems could be avoided by using a HTML validator.

"Exception in thread "main" java.lang.NoClassDefFound Error" in XP

I was creating programs just fine for awhile. Then, for some unknown reason, I start getting the runtime error message, "Exception in thread "main" java.lang.NoClassDefFound Error." I set my PATH in the following manner:
Start | Control Panel | Performance and Maintenance | System | Advanced | Environment Variables | Use Variables for Owner | PATH | Edit | C:\j2sdk1.4.2_04;C:\j2sdk1.4.2_04\bin;C:\j2sdk1.4.2_04\jre\bin | Ok | Ok | Ok
I then closed the dialog boxes and restarted my computer. I then tried to run a program that ran before, only to get the same runtime error! Can someone please help me???

NoClassDefFoundError happens because the JVM cannot find some class from your program, not because the OS cannot find your JVM (PATH regulates the latter, but not the former). JVM looks up classes in directories (or JAR files) specified through the -classpath option, like "java -classpath c:\myclasses MyMainClass". Read the online doc for the "java" launcher for more info.

Anyway @NovaKane: Welcome. Together with seifist and sunny we have at
least three new posters who show enough intelligence to find chuck's
solution (or one of the many hundreds of others like it) and the politeness
to thank him for it. What's the forum coming to?
If you need it there is a description of the classpath here:

Again, welcome. And thanks for raising the intelligence level (and politeness
quotient) of the fora.

Java.lang.NoClassDefFound Error:msgsend

Hi,
I am trying to run my first Java Mail program, sending mail.
I had compiled the source - no Errors.
Now, when i try to execute it says
Exception in thread 'main' java.lang.NoClassDefFound Error:
I have download the JavaMail and JAF and has put the files under proper dir and verified the class variable. I am using Jdk1.3.

The reason of this run time error is : Java is not able to locate main method of specified class File. or class file itself is not locatable.
Check :
1. Either u are not in same folder where ur class file is.
2. or If u are running from some other directory, ur class file path is not in CLASSPATH.
3.or There will be some mistake in definition of main method.
Bye,

Java.lang.OutOfMemory error while retrieving data from a large table

Hi,
i am trying to fetch data using "executeQuery()" into a ResultSet from the database. But since the data in that table is large. i am recieving "java.lang.OutOfMemory" Error. So, to resolve that, i have used "setMaxRows()" for my statement object. This resolved the error but i don't recieve the entire data. If i call "executeQuery()" again, i recieve the same data. I don't even know a filtering criterion where by i can filter the data for each "executeQuery()"..
How can i resolve this problem
Thanx in advance
