Java class not found error - BI Publisher v11.1.1.3.0

Hi,
we've just started to look at BI Publisher v11.1.1.3.0.
When we try to use the scheduler, the Weblogic logs inform us of a :
java.lang.NoClassDefFoundError : oracle/as/scheduler/RuntimeServiceHandle.
Although this is probably a long shot, would anyone know in which .jar file the class oracle.as.scheduler.RuntimeServiceHandle is contained, and where it would be possible to obtain that .jar file from?
Thanks,
Andrew.

I am having a similar issue, how did you get past this issue?

"Java Class not found in classpath" Error in DESIGNER

Hello All,
I'm trying to connect in Designer using a JDBC connection to MS SQL Server 2008. As per the instructions, I updated my jdbc.sbo file with the path to the existing two JAR files. However, I still get the following error when I try and connect in Designer: "Java Class not found in classpath : C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\jdbc\Drivers\sqlsrv". Of course, this error includes the drive path with the location to my JAR files. Any help in resolving this nagging issue is very GREATLY appreciated. Also, if anyone needs it I can post a copy of the jdbc.sbo file to this thread.
Thank you,
Pankaj

Stratos,
Your suggestion didn't help. I tried to connect after restarting my machine and I still get the error. And, I've also tried adding a connection to MS SQL Server 2005 using this JDBC driver, and that didn't help either. Any other suggestions? Would it help to see my "jdbc.sbo" file? Thanks again for your and everyone else's help, and I look forward to your reply.
Regards,
Pankaj

Hi,
Verify the 3rd party class files names are correctly written in your program. Sometimes wrong case might be the reason.

Class not found error afer loading classes to oracle

hi i have loaded quite a few jars into oralce 11g databse
created a java stored function
and executed it
some times it works... and hits the java front end environment... we are hitting a servlet.. and recording some output statements .. in the function
but sometimes it throws class not found error
any idea why its working sometimes and not some othr times?
Also when i load the jars.. the classes are loaded but when i see the name of the classes using
select * from user_objects where object_type like 'J%'
then i see some additional characters prefixxed the class names ... is that causing the problem?
something like this

Learning_man,
Obviously you need to learn how to ask a question.
There is nothing in your post other than 'It doesn't work. Why? Help"
without any specific example. Also you still fail to include a 4 digit version!!!
It is also the third or the fourth time you asked this very same question.
Can you learn how to ask a question please? And stop repeating the question when you don't get a response?
And no, the extra characters are not the problem.
An incorrect CLASSPATH probably is.

Class not found error for applet.

This is probally a really simple mistake but I've tried everything and can't find it.
My applet works fine with applet viewer - I'm running it from JBuilder. But when I open my html file in the browser it gives me a 'Class not found' error. I've tried running other applets (my own and demos on this site) and they work fine.This is the applet tag code:
<applet code = "Rotary.class" width = "650" height = "580" align = "top">

<param name = "sector0" value ="234,215,244,207,154,43,125,63">
</applet>
The class file is in the same directory as the HTML file. Do I need to specify the codebase? I tried that too - giving it the full pathname of the class.
In the Java console it said that it couldn't find "C:Project\Rotary\javax\swing\japplet"
I don't think it could have anything to do with the fact that I'm using swing because the other applets I used used swing.
Please help - I'm really running out of ideas here!

You have a similar problem like I had.
You seem to have a too old JAVA environment for the browser - I had a too new environment.
For all who are experiencing the same problem!
Problem:
You're compiling your applets with a quiet modern compiler (i.e. Netbeans Version 3.5.1)
You are able to compile your applets without any problems but if you try your applets in "real life", the browsers can't interpret your applets [class not found]. (I tested Internet Explorer 6.0 and Netscape Navigator 4.7)
So you need a plugin for the new JAVA environment because the JAVA environment of the browser is older than that which the applet needs.
Well, you have the choice to demand to every user of your applet to download the new Java Runtime Environment, but then don't wonder why nobody visits your site!
But, don't worry: I figuered out another solution, that Netbeans (www.netbeans.org) allows to compile in different JAVA versions.
Solution:
What you have to do is:
- Install a previous version of JDK (i.e. JDK 1.3 - I would suggest, lower versions don't work with Netbeans 3.5.1 and JDK 1.3 is enough for IE 6.0 and NN 4.7, which I tested)
- Go into the "bin"-directory of Netbeans (i.e. c:/netbeans3.5.1/bin)
- Open the file "ide.cfg" (with notepad or any other texteditor)
- You see a line like: jdkhome "C:\java\j2sdk1.4.2" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- Change the path to your other JDK you wish, like: jdkhome "C:\java\jdk1.3" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- That's it, you can compile your applets in a previous version of JAVA so that "older" browser user don't have to install a plugin for the new JAVA environment.
Have fun!
If you have any questions I would be pleased to help you.
If this tip helped you already I would be pleased if you would send me a quick email with your experience.

Servlet class not found error deploying a WAR on Web Logic Server 8.1

I'm re-deploying an updated web application to a web logic server, but when I navigate to the login page of the web application to test it, I get a class not found error for my login servlet. I have both the web.xml and the weblogic.xml descriptors in my WEB-INF directory, and all of my compiled classes are in the WEB-INF/classes directory, is there something else I'm missing? Any help would be much appreciated.

Thanks for the response. Here's the web.xml file:

None of the classes are in a package (I know it's not the best idea, but I didn't write these, I'm just doing some updates). So the file structure is pretty much just WEB-INF/classes/
At the moment I've got a fix by just putting the entire project (not in any sort of archive) on the server itself instead of deploying it as a WAR, any thoughts on why the WAR isn't working would be much appreciated though.

WLS 7 SSL class not found error

Actually, I got the same error message to start the Node Manager. However, I don't
have the RSA license at this moment. How can it make the WL to use com.certicom.net.ssl.CerticomContextWrapper
instead of com.rsa.ssl.WeblogicContextWrapper?
Thanks,
Victor

Certicom classes are shipped in weblogic.jar, you must have RSA license,
but
no RSA SSL classes in the server classpath?

Class Not Found Error during provisioning

Hello,
I am running on jboss-4.0.3-SP1, OIM 9.0.3 latest patch. I am new to this implementation and just rebuilt the dev environment. I am checking the provisioning of the resources and ran into a class not found error.
The error says:

Then I made sure the jar file named cpsgUnix.jar is present in the OIM_HOME/JavaTasks directory.
But still I have the error.
What am I missing?

I added the sshfactory.jar file in the JavaTask folder and it worked.

"class not found error" and applets ...

To run an applet inside an html page using the embedded oc4j i have to copy the library containing the applet to the same directory as the html page. Otherwise i get a class not found error....Is there a better way of doing this?
thanks in advance for any advise

Hi,
you should be able to reference the JAR file from teh HTML tag. If not then this sounds like a bug that should be filed

"Class not found" error at runtime when ExternalLib DC is included in WD DC

Hi All,
I am getting "Class not found" exception at runtime when external library DC is included in Webdynpro DC.
I am following the below steps..
1) Created a Webdynpro DC - "testProj" to which i need to add the external library DC.
2) Created a DC of type "External Library" called "externaljar"
3)Added Public Parts of type assembly and compilation to the "externaljar" DC (Component Properties Tab -> Public Parts)
4) Right click on the assembly Public Part name -> Manage entities, and added the JAR files as archive.
5)Right click on the compilation Public Part name -> Manage entities, and added the JAR files as archive.
6)Go to Webdynpro DC "testProj" .
Under Component Properties Tab -> Dependencies tab -> Add -> selected the "externaljar" DC -> Next -> for "externaljar" DC checked Deploy time and Run time.
For assembly Public Part and compilation Public Part "build" is selected by default.
7) I did build of both the DC's and deployed it.
Im getting "Class not found" error.
Please let me know where i am going wrong.
Thanks,
Shilpa.

Hi Balakrishna,
If I add Jar files in build path, at run time I dont get any errors, but I get error at comple time. So an external DC is made which includes all jar files in its public part and this DC is added as dependency in the webdynpro project (at deploy time,run time) as in below blog.

Here im getting the error "class not found".

Class not found error over HTTPS connection

Problem: Facing problem in downloading signed JAR file over HTTPS connection.
While downloading the jar file over a https connection, i get a certificate with following message
" Do you want to accept the certificate from web site <server name> for the purpose of exchanging encrypted information? "
If i accept the ceritificate immediately without any delay, all goes fine. The jar file gets downloaded and the applet runs withoput any problem. But if we accept the certificate after some delay say after one or two minutes i get "Class not found error"
Has anybody come across any such issue ?
Thanks in advance.
Rohit

I got the same error. I believe the ssl connection has a short timeout.
But I don't think this is a bug because there is no sense in letting a ssl connection open in the initial state before accepting the server's certificate.

Getting the Adapter Class Not Found Error in the Java Manipulator

Hi,
I wrote a custom java manipulator for the baseline update and created a jar file for the class. This works fine in the Windows machine. All I have to do is while specifying the CLASSPATH, I entered the ./ib/newManipulator.jar; ./lib/additional_dependency.jar. When I tried to deploy the same code in the Unix environment, it fails saying the Adapter Class not found. The only difference from windows and Unix environment is that in the windows machine, in order to run the base line update, I go to the directory my_project->control->baseline_update.bat but in case of Unix environment I have a separate location where I have a shell script called run-baseline-update.sh located at /apps/bin which invokes the baseline.sh in the directory my_project/control/baseline.sh. I even tried to put the full path of the jar files e.g. /my_project/lib/newManipulator.jar; /my_project/lib/additional_dependency.jar in the class path but still the same issue. Any suggestions?

Unix classpath needs ":" as the path separator, not ";". Changing that will make this work.
For reference, later versions of the deployment template make this configurable, so you'd see (in environment.properties):
# PATH_SEP_VARNAME: for platform-independence
PATH_SEP_VARNAME=;
# Forge needs record store libraries as well as Spring to load record store adapter configuration files
FORGE_CLASSPATH=./config/lib/java/spring-delegate-adapter-1.0.1.jar${PATH_SEP_VARNAME}./config/lib/java/spring.jar${PATH_SEP_VARNAME}./config/lib/java/eacToolkit.jar${PATH_SEP_VARNAME}./config/script${PATH_SEP_VARNAME}.
You can then add the following to your <forge /> definition in AppConfig.xml:
<arg>--javaClasspath</arg>
<arg>${FORGE_CLASSPATH}</arg>
Hope this helps.
