Java.lang.NoClassDefFoundError: oracle/sql/CharacterSet

Okay, I give!
I keep getting this runtime error when running this program I wrote.
the oracle directory (where all the classes are stored) resides in the directory where my Class files live. I even added: ./
to my classpath, but that didn't help at all.
I navigated to: oracle/sql and did find CharacterSet.class
What's even stranger is that I developed this application on a Sun/Solaris machine using Java 1.2.2 then I deployed it on a Sun/Solaris machine with Java 1.3 (but I am not using any of JDK's 1.2 stuff... its all just plain java).
Very strange. Any input as to what this problem may be I would appreciate some guidance.
thank you!

If you are using the OCI driver, you may need to include the NLS classes:
nls_charset12.zip
In the classpath.

Tomcat: java.lang.NoClassDefFoundError: oracle/sql/NUMBER

hi,
i have managed to come this far with my "simple" webapplication under tomcat.
the exception is:
java.lang.NoClassDefFoundError: oracle/sql/NUMBER
since i have tried to put the classes12.jar in every reasonable directory without effect, i have to bother this forum. does anyone know "where the dog is burried"(german saying)?

Hi yves,
This class is in the jdev_home/jdbc.lib/ojdbc14.jar.
But prior to deploying your ADF application, did you install the ADF runtime libraries to Tomact as explained here?:

Java.lang.NoClassDefFoundError: oracle/sql/STRUCT after 11g/GF3.1.2 upgrade

We have recently upgraded all of our servers from:
Java 1.6.31 to 1.6.32
and
Glassfish 3.1.1 to 3.1.2
We upgraded our development server from Oracle 10g to 11g.
Our live servers are working fine. Our development server now is spewing out a java.lang.NoClassDefFoundError: oracle/sql/STRUCT error whenever it encounters a servlet or page which uses this class.
ojdbc14.jar and sdopai.jar were included within the WAR file, and I have tried with them excluded from the WAR file to no avail. We have tried reverting the version of ojdbc.jar on the server to the earlier version, this has made no different.
Any ideas? The full stack trace is below:

If your code can't find the class then you have the classic NoClassDefFoundError problem you get when any other referenced class can't be located.
The oracle/sql/STRUCT class is in the ojdbc14.jar, ojdbc5.jar and ojdbc6.jar so if it can't be found then that class is missing from the jar you are using (which you can tell by examining the jar contents) or the jar is missing from the classpath being used.
As already mentioned you need the Oracle 11 JDBC files to support Java 1.6
Here is the official Oracle JDBC page that shows the Oracle DB versions supported for each of the JDBC drivers available and also describes the JDBC jars and what JDK versions they support.
http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-faq-090281.html#02_01

Which JDBC drivers support which versions of Javasoft's JDK?
pre-8i OCI and THIN Drivers - JDK 1.0.x and JDK 1.1.x
8.1.5 OCI and THIN Drivers - JDK 1.0.x and JDK 1.1.x
8.1.6SDK THIN Driver - JDK 1.1.x and JDK 1.2.x (aka Java2)
8.1.6SDK OCI Driver - Only JDK 1.1.x
8.1.6 OCI and THIN Driver - JDK 1.1.x and JDK 1.2.x
8.1.7 OCI and THIN Driver - JDK 1.1.x and JDK 1.2.x

Please note that JDK 1.4 is not supported by the 11 drivers.

Java.lang.NoClassDefFoundError: oracle/sql/Datum

Greetings -
When using the Oracle XML SQL Utilities is there some sort of restriction as to where the two jar files (oraclexmlsql.jar xmlparser.jar) are referenced from.
The reason I ask is that when I deployed my servlet based application under WebSphere - I received the above class not found error and had to change my setup to specify the two jar files as part of the command line options for the WebSphere program itself.
Now I am using JRun and have the same error - unfortunately JRun doesn't like me overriding the classpath on the command line - so I have been unable to come up with a workaround.
I would appreciate any comments or suggestions.

Thanks - I realize that App Servers have places to specify classpaths, and JRUN uses the standard JSDK 2.2 Web Application setup with the WEB-INF directory structure. All of my other jar files are there and work fine - the problem is with the xml/sql and xmlparser jar files from Oracle - they only seem to be found when I specify them as a -cp arg to the JRun executable. Which is causing problems for JRUN. I was wondering if there was any other solution to this problem.
Thanks - Gary

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Steven Muench ([email protected]):
Only thing I can think of is that maybe your server classpath is getting too long. I recall one of the Java Web Server releases having a classpath length limit that caused strange errors like this because that .jar files you thought were on your classpath were getting their path names truncated so the Java VM cannot find the JAR's.
Try putting xsu111.jar earlier in the list of JAR's and/or try shortening the classpath (perhaps by using SUBST'd drive letters or softlinks on Unix to shorten the path names).<HR></BLOCKQUOTE>
Putting the xsu11.jar file towards the start of the path did not help.
I have rewriten the entire bat file that creates the CLASSPATH and starts the server and things now seem to work. There must have been some error in the original bat file, that I just couldn't see.
Anyway - I thank you for your help.

XSLException
Hi
I have downloaded XDK and was trying to use the XSU feature..
I unzipped the XDK file, I ran the following query on SQL plus
select * from emp. It displayed the full table.
Then i set the class path for XDK,XMLparserv2,oracle JDBC driver and then ran the same query on dos prompt(that is front end command line for java in my case).
The following is the line i tried to execute on the command prompt
java OracleXML getXML -user "scott/tiger" -conn "jdbc:oracle:thin:@localhost
:1521:PomonaT" "select * from emp"
PomonaT is the db name(Host string i use to enter SQL+)
I get the following error

The first is that 10.2.0.1 is unpatched. Why? It has been two years since its release and no one has applied 10.2.0.2, 10.2.0.3 or 10.2.0.4.
The second is that your question is not a database question but a Java question is you are more likely to get an answer that will help you if you post in a group where it is on-topic.

Java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver

I am trying to connect from a servlet running in Tomcat on my desktop to an instance of Personal Oracle9i running on my desktop. I am gettiung NoClassDefFoundError. The code compiles.
I know it is a path issue but I am at a loss to figure out where. Tomcat does not find the driver however it is in my machines path.
Running following:
j2sdk1.4.1_02
Personal Oracle 9.2
Tomcat 4.1.29
Windows XP
I have added the location of Classes12.zip to the class path: .;c:\Sun\AppServer\lib\j2ee.jar;c:\Sun\AppServer\lib\j2ee-svc.jar;d:\oracle\ora92\jdbc\lib\classes12.zip;
The "root cause" of error is:
java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver
     at OOP.OracleConnectionDemo.doPost(OracleConnectionDemo.java:34)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)
The code is as follows:
import java.sql.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import oracle.jdbc.OracleDriver;
//import oracle.jdbc.driver.*; //did not work either
public class OracleConnectionDemo extends HttpServlet {
     public void doPost(HttpServletRequest req, HttpServletResponse resp)
          throws ServletException, IOException{
          Connection con = null;
          // Load the Oracle JDBC driver
          try{
               //two versions did not work
               //DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver);
          DriverManager.registerDriver(new OracleDriver());
     con = DriverManager.getConnection
               ("jdbc:oracle:thin:@micron.1521:MCAP","scott","scott");
          catch (SQLException e){
          catch (Exception e){
          finally{
               try{
                    if (con != null)
               con.close();
          catch(SQLException ignored){
          }//finally
}

What you should be realizing is that Tomcat doesn't give a hoot about your system CLASSPATH. It totally ignores it. You really shouldn't even have one, because IDEs and app servers don't even take it into account. Get rid of it.
You're making lots of mistakes here:
(1) The Tomcat docs explicitly state that it won't look inside ZIP files. Change it to a JAR file.
(2) You're using JDK 1.4.1 and classes12.zip? You realize, of course, that there's an ojdbc14.jar available for download from Oracle. Go get it.
(3) Put the JDBC JAR in the WEB-INF/lib directory of your Web app. If you don't have one, you're not deploying your Web app properly.
(4) You've got Java code with empty catch blocks? That's one of the most foolish things a person can do. If an exception's thrown you'll never know it. For goodness sake, at least print the stack trace.
(5) Why do you have those Oracle imports? That ties your code to Oracle. The design of the java.sql package lets you use interfaces. Why don't you write JDBC the way it was meant to be written?
(6) Why aren't you setting up a JNDI data source?

Exception in thread "main" java.lang.NoClassDefFoundError: oracle/xml/parser/v2/

Hi!
Kindly assist on the following error.
I'm doing the sample acmevideo on Cashier Application deploying as a Java Application from JDeveloper3.0 and Oracle8i 8.1.5. And I had this error after executing the following command;

Make sure the classpath for the application includes all necessary dependency archives.
The error in question is referring to the XMLParverv2.jar. This needs to be in the application's classpath when you launch it.
The jar is available from JDEV_HOME\lib.

Issue with java.lang.ClassCastException: oracle.sql.StructDescriptor

Hi ,
I'm creating a dbadapter for a custom API written in APPS schema -
TYPE MISIPM_LOB IS RECORD (
FILE_ID IPM_LOBS.FILE_ID%TYPE,
FILE_NAME IPM_LOBS.LOB_NAME%TYPE );
TYPE MISIPM_LOB_LIST IS TABLE OF MISIPM_LOB;
PROCEDURE GET_FILE_ID_DETAILS(
P_SOURCE_SYSTEM IN VARCHAR2,
p_entity_value IN VARCHAR2,
p_entity_code IN VARCHAR2,
P_ORG_ID IN NUMBER,
P_MISIPM_FILES_LIST OUT MISIPM_LOB_LIST,
P_ERRCODE OUT VARCHAR2,
P_ERRMESSAGE OUT VARCHAR2);
From JDeveloper, there is a wrapper package is getting created and the compilation/deployment of this composite is also without any error.
But when I run the composite, I'm surprisingly getting the below error -
Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'GetAttachmentMetaData' failed due to: Interaction processing error. Error while processing the execution of the APPS.BPEL_GETATTACHMENTMETADATA1.XX_DELIVER_BLOB$GET_FILE_ API interaction. An error occurred while processing the interaction for invoking the APPS.BPEL_GETATTACHMENTMETADATA1.XX_DELIVER_BLOB$GET_FILE_ API. Cause: java.lang.ClassCastException: oracle.sql.StructDescriptor Check to ensure that the XML containing parameter data matches the parameter definitions in the XSD. This exception is considered not retriable, likely due to a modelling mistake. ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.
I recreated the adapter multiple times within the composite and also tried to create a separate composite and all the cases the error message received was same. There two more similar procedure call's in the composite and all rest of them are working fine.
I can call the wrapper from sql script separately.
Verified that the XSD generated and the wrapper package parameters are matching as well.
Did anyone face the same issue or any explanation/help is much appreciated.

Debanjan

Does the installation file for oc4j missing some libraries? I thought they would be already installed? Should I manually copy them from the embedded oc4j from my Windows installation. If yes, which files?
Please help.

You need to configure oc4J_extended with BC4J runtime libraries in order to run BC4J applications.

ADF / Jdeveloper DVT - java.lang.NoClassDefFoundError: oracle/dss/util/tran

Hi there,
I have deployed an application to a weblogic server and one of my pages contains a DVT graph. The application works fine until I attempt to navigate to this page, and incur the following error:

I have reviewed the following article which contains the exact issue:
http://cn.forums.oracle.com/forums/thread.jspa?threadID=1129729&tstart=59
however, do not know if what I have done is correct.
I right click on the view controller > Deployments > Edit > Web Inf / Lib and have ensured that ADF Faces Runtime 11 and ADF DVT Faces Runtime are ticked (these weren't initially). ADF DVT Faces Databinding Runtime was already ticked by default.
I have also attempted this through the EAR via Application > Application Properties, but when I include these in the EAR I receive a deployment error.
Any help with directions or more specific instructions would be much appreciated.
S
Also -
THe deployment in this instance completes sucessfully, and takes a little longer to deploy, so I do know that something is happenning. However, I still experience the same issue. Is there something that I need to do on the remote server?

Can I also add, that when I check the WAR file in my deployments folder, I can see the appropriate java classes.
They are not however included in the EAR.
Do they need to be in the EAR as well?
Again, to reiterate, when I try doing this, the deployment fails.
Simo

Those classes seem to deal with general management.
However, OracleSSLSocketImpl cannot be found, which makes me guess that you have
some kind of non-SSL enabled version (trial perhaps?) of the Orcale software. Can it be the case?
Or that you need to place another Oracle supplied jar in your classpath to get SSL to work?

I found there is leak of memory resource on the Oracle RDBMS host while this problem occurs,the database host has only 512Mb RAM.And I once configred the database to worked on Shared Mode,in this case the database has less chance of memory leak,but the above exception occurs more often.So I have to change the database to work back on Dedicate Mode!It's hard to find any tips on my Exception as mentioned above.
And I want to know the working principle of servlet on iAS.When invoke a servlet,will the servlet be cached on Memory from the first request,or it will be clear up and re-inload until next request?I just wonder if the iAS server will run out of memory,because I noticed there is a memory configure option in "jser.properties" file.And the exception I encoutered seems to occur at a critical point.

Thanks but that did help since they are talking about
JDK1.3. I downloaded J2SDK-Beta 3 it says that you
don't need to set a class path variable. You need to be careful about how you interpret this statement. The rule is, if your system doesn't have a classpath set, you'll get a default of the current directory (.). If your system does have a classpath setting, then the setting will be used.
Just because you didn't set your classpath doesn't mean someone or some other application didn't. Make sure that your system doesn't have a classpath setting. If it does, you may need to add the current directory (.) to it.
