Class not found when using JvmModelInferrer

I am trying to transform one of my language elements to a class using the ModelInferrer approach. This generated class should extend a class (AbstractMatcher) from an external project. The external project is added to the build path of the Xtext model project as an external class folder and to the run-time project in the same way. It should be noted that the external project is a plug-in built in Helios SR1. I am able to reference the AbstractMatcher class from the xtend source code (it is available for auto complete and imported correctly), but when I start runtime eclipse, I get a java.lang.NoClassDefFoundError when trying to add a superType to the generated class. If I substitute the AbstractMatcher with a dummy like java.util.ArrayList everything works fine. I have tried to make a simple Java class inside the runtime Java project and reference the AbstractMatcher from it and this also works fine. Everything seems to be able to find the offending class except the ModelInferrer.
import external.package.AbstractMatcher
def dispatch void infer(Matcher matcher, IJvmDeclaredTypeAcceptor acceptor, boolean isPreIndexingPhase) {
acceptor.accept(matcher.toClass("matchers." + matcher.name.toFirstUpper + "Matcher")) [
superTypes += typeRef(AbstractMatcher) // <---exception here

I sense that this is actually an OSGi problem, since I see this is how typeRef tries to find the reference, but I don't know how to get around it. I am not able to add the external plugin containing the AbstractMatcher class as a dependency and I'm not sure if it would be possible due to different Eclipse versions (Helios vs Luna).

Does it work for you if you refer to the AbstractMatcher from Java-code
that is in a project in the runtime instance?

I have also tried to open on 6.1 with similar results.
I am familiar with lookout, however I have taken this project over so I am not sure what I need to do from here.

There are two object (DirectLogic and Meter) that are not present on the amchine you are moving the process to. If the same version of Lookout, you might be able to just copy the cbx files.

Error oracle.sql.* and oracle.jdbc.driver.* not found when using oracle as a database

I am using oracle as database and weblogic 4.5. I have copied the classes12.zip file in lib directory of weblogic. I am getting the error that oracle.sql.* and oracle.jdbc.driver.* not found when i am importing these packages in a jsp file. what i need to do to import oracle driver packages?I put it in the classpath also.
Please Advice!
Thanks in advance
AnuPama

Hi Anupama,
First of all I would be surprised if you would not like to use the connection pooling feature of weblogic (in which case you might not be needing the import the classes directly), and would like to open direct connections to your database. Anyways for doing that I would recommend you to check out the readme doc that ships
along with the jdbc oracle (classes12.zip etc). I am giving an excerpt over here:
These are a few simple things that you should do in your JDBC program:
1. Import the necessary JDBC classes in your programs that use JDBC.
For example:
import java.sql.*;
import java.math.*;
2. Register the Oracle driver before before calling other JDBC APIs.
(This is not needed if you are using the JDBC Server-side Internal
Driver because registration is done automatically in the server.)
To register the Oracle driver, make sure the following statement
is executed at least once in your Java session:
DriverManager.registerDriver(
new oracle.jdbc.driver.OracleDriver());
3. Open a connection to the database with the getConnection call.
Different connection URLs should be used for different JDBC
drivers. The following examples demonstrate the different URLs.
For the JDBC OCI8 Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:oci8:@<database>",
"scott", "tiger");
where <database> is either an entry in tnsnames.ora or a SQL*net
name-value pair.
For the JDBC Thin Driver, or Server-side Thin Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:thin:@<database>",
"scott", "tiger");
where <database> is either a string of the form
<host>:<port>:<sid> or a SQL*net name-value pair.
For the JDBC Server-side Internal Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:kprb:");
Note that the trailing ':' character is necessary. When you use
the Server-side Internal Driver, you always connect to the
database you are executing in. You can also do this:
Connection conn
= new oracle.jdbc.driver.OracleDriver().defaultConnection();
Hope this helps,
Thanks,

Class not found only using browser.

I can not run any of my java programs in my browsers. They work fine using the "java" command in a dos window or using the "appletviewer" command. But when I try to view them in a browser, the page appears to load fine but I get no program and the status window of the browser displays a class not found msg.
I've checked spelling, location, capitalization. Everything works fine outside the browsers but will not view in a browser. We had the same problem in school and the instructor just said to stick with the appletviewer for class.
I am running JDK1.2. Any suggestions?
John

Maybe you should try a newer JAVA version.
I had a similar problem, but with a (too) newer JAVA version.
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.

Class not Found when accessing Proxy class from backing bean in VC.

Hi All,
I'm attempting to access a class of a webservice(generated as a proxy) within my ADF application and invoke the method within a backing bean of the View Controller(bean scope : backing bean). The proxy has generated an ObjectFactory class among other classes. When I access this Object factory class from within the backing bean, the application throws a Class not found error.
I don't know where the error lies since I've declared the View Controller of the ADF application dependent on the Proxy and I've imported the class and accessing it within a backing bean. How would you suggest I approach resolveing this.
JDev : 1.1.1.4
Thank you.
Regards
PP.

Hello Arun,
Thank you for suggesting a Data control, but my requirement isn't to drag and drop the method as a button. It's more of a behind the scnes updating data via a database adapter requirement.
I've resolved the issue. turns out, my deployment archive didn't include the proxy.jpr. Once included it works likea charm.
Thanks
PP.

Class not found when I run JSPs

I set up and can run JSPs in iPlanet 4.1 SP9 on NT. But if I use anything
such as Date() I get a Server Error and a Class Not Found in the error log.
Can someone tell me how to confire where the .class and .jar support files
go, or where do I put them. In the JDK install directory or in the iPlanet
install directory.
Thanks, Gary

Something to note, you must have superuser priveleges to run ibconf.
Check out this document about installing a PCI-GPIB on a Solaris machine. There is a section in it on page 9 about configuring the software with ibconf.
If you still have problems after reading through this repost.

Jre not found when using Loadjava command

Hello,
I am getting an error when I run the below load java command on a 9.2.0.8 database on Sun/Solaris platform.
Command:
loadjava -user user/[email protected]:1529:OLS2 -thin -force -resolve -verbose filename.jar

When I tried creating a new Jre soft link from $ORACLE_HOME/bin like : 'ln -s $ORACLE_HOME/jdk/jre/bin/java $ORACLE_HOME/jdk/jre/bin/jre' its giving a new error:
jre was not found in /olcdbt/u01/app/oracle/product/9.2.0.8/jdk/jre/bin/../bin/sparc/native_threads/jre
Strange thing here is that this was working fine in 9206 home and after upgrading to 9208 1 month back I am facing this issue. I am sure I am missing something here but not sure what.. Please help me resolve this issue.
Regards,
Raji.

Hi,
Even though the problem manifests when using loadjava, it has noting to do with the embedded Java VM in the database; it's rather an install /upgrade problem.

Hi,
'Class not found' in the Mapping Workbench usually means that one of your classes was not included in the 'class path' panel. In the Mapping Workbench select the project -> Class Path -> Add Entry...
For example, in my case I have Person.class, which is part of the package com.toplink.course. 'C:\dev\tl400\classes\com\toplink\course>Person.class'
So in the Mapping Workbench -> Class Path I put 'C:\dev\tl400\classes'

Class not found while using rmic.exe

This is my first RMI program, so bear with me.
After compiling both my object interface class file and my object implementation file (both with no errors), i move on to create the stubs/skeletons (or whatever they are called). After executing rmic MyObjImplementation, i get an error saying the following - "error: Class InputDeviceImpl.class not found."
I dont understand this, the .class file is indeed in the directory, and i know the rmic.exe sees it because i have tried to type "rmic *.class" and it gives the same error for every .class file in the directory.
whats going on?
-joey

well i figured out to compile the program, but i still dont understand what happened. I read the tutorial on this website, and it told me to start the rmi registry first. So does this mean that i have to do this each and everytime?

JAXB 1.0 Final: jaxb.properties not found when using custom classloader

JDK 1.3.1 is being used.
The scenario:
1) jaxb jar files, jaxb generated files and application files loaded in default class loader works, however
2) jaxb jar files, jaxb generated files and application files loaded in a custom class loader generate the following exception:
javax.xml.bind.JAXBException: Unable to locate jaxb.properties for package XXX
To demonstrate here are two sample applications: a Launcher app whose job it is to start apps and a sample App1 application who needs JAXB.
If launch is placed into a jar file named launch.jar and App1 is placed into a jar file named app1.jar (with a JAXB generated package), and both jar files are placed in a directory containing all the JAXB 1.0 jar files (dom, sax, namespace, etc) and the system is started with the following:
jre\bin\java -cp launch.jar; testLaunch.launch
the exception occurs.
By way of comparison, if App1 is started directly with the following:
jre\bin\java -cp app1.jar;jax-qname.jar;jaxb-xjc.jar;jaxb-ri.jar;jaxb-libs.jar;jaxb-api.jar;dom.jar;sax.jar;jaxp-api.jar;xercesImpl.jar;namespace.jar;ant.jar;xalan.jar testApp.app1
the exception does not occur.

I'm doing something very similar. In fact my launcher is also stored in launcher.jar. It will start any application on the classpath and load dependencies jars located in the specified directory.
The first thing you must do is specify the classloader when constructing the jaxb context:
JAXBContext jc = JAXBContext.newInstance(xmlPackage, getClass().getClassLoader());
After this I was still raning into the "jaxb.properties not found" exception in some situations. Basically if the class using the jaxb files is located in the same jar as jaxb.properties everything worked fine. However if the class using the jaxb objects was located in a different jar it did not work.
I had to add the following early in the execution of the application that load the plugins to get things working correctly:
Thread.currentThread().setContextClassLoader(jarDirClassLoader);
As far as I can tell JAXB using the Context class loader to find the jaxb.properties file.
I'm using JAXB 1.1
I hope this helps!

Webutil bean not found when using call_form with no_share_library_data

Hi,
I have two Forms modules and i navigate from Form A to Form B using a call_form.
If i call Form B with NO_SHARE_LIBRARY_DATA param, i get a webutil error: "oracle.forms.webutil.file.filefunctions bean not found"
If i call it with SHARE_LIBRARY_DATA, there no error and my webutil function works as expected.
Webutil is used in our application are works well so i don't think that it's webutil config problem.
Any idea?
Tx

Thanks for your answer.
Now I'am a little bit further with my debugging but it's more strange! forget the share_library_data...
I start a common form with webutil.pll attached and i will use the Webutil_File.File_Exists function for example
if i call it in the WNFI or WNBI, i get the error
if i call it via a push-button WBP for example, it works!
below the java console ouput when i get the error and after pushing ok on the error

Fonts not found when using Xvfb

Hi all,
I keep encountering "fonts specified in fonts.properties not found" whenever I execute rwserver.sh server=XXX.
fyi, I'm running Solaris8 on Sun SPACE machine. I use Xvfb downloaded from Oracle to allow report server to run after I logoff from the session. I realised that the report sever I created manually will die prematurely if I log out from the session when I use the "default" Xserver provided by Solaris.
And prior to running rwserver.sh I set the DISPLAY such DISPLAY=:1.0; export DISPLAY.
pls advise.

I get the same errors on my Solaris system with xvfb, but it doesn't keep anything from working. My reports server comes up and works fine.

Start with a simple and obvious search string. If you give us an example of a search string that did not work we could have a look at it for you.
