Unable to load jar file-Urgent

Hi all,
I am using AltaVista search engine in my project. I have uploaded the jar file related to this into Weblogic 8.1. But many times application doesn�t able to take files from mentioned jar and gives me an error message that couldn't find the class. I always need to start the weblogic again & again to start the search engine functionality. Please help me out why it doesn�t pick the jar file.
Thanks & Regards

Urgent: Does dbms_java package is required to load jar file into database?

Hi, It's a urgent request. I am trying to install jar file that was created by JDeveloper into database using loadjava. But it is giving so many errors.
Do we need to install dbms_java package in order to load jar files into the database? Thanks.

Thanks for your reply Kamal.
I am trying to load these jar files into Oracle 9.2.0.3.20 database.
Could you please give me the list of the steps to enable java within the database? Thanks.

Adogjf Unable to generate jar files under JAVA_TOP error while patching

Hi,
I'm upgrading my version of Java from 1.3.1_19 to 1.5.0_17. I downloaded the jdk-1_5_0_17-linux-i586.bin file and unpackaged it to /u0/<SID>/<SID>db/10.2.0. It unpackaged it to a new directory jdk1.5.0_17 (/u0/<SID>/<SID>db/10.2.0/jdk1.5.0_17), whereas the old version is in a directory jdk (/u0/<SID>/<SID>db/10.2.0/jdk).
Having done that I had to run an interoperability patch (4372996). Upon running this patch I received an error at the end:
adogjf() Unable to generate jar files under JAVA_TOP
There were no other errors.
I think the problem has to do with where my new java version is located but I'm not sure. I'm thinking that it's still looking under the old JAVA_TOP (/u0/<SID>/<SID>db/10.2.0/jdk) when I want it to look under the new JAVA_TOP (/u0/<SID>/<SID>db/10.2.0/jdk1.5.0_17). So, should I move the contents from the new directory (jdk1.5.0_17) to the old directory (jdk) or is there a way to 'point' it to the new JAVA_TOP.
Please let me know if I'm totally off base and there's another solution. We're currently on EBS 11.5.10.2, DB 10.2.0.4 and RHEL 4 Update 5.
Thanks,
Lia.

Here you go. Hope this helps you to help me :-). Thanks.

Unable to execute JAR files

1.4.2_04 SDK
But no change in the outcome.
The javaw application starts but does not load the jar file.

Sorry i have tried to format the code, but it has changed to �... sorry read this one...
Hello All,
I'm making a Java SQL Client. I have practicaly all basic work done, now I'm trying to improve it.
One thing I want it to do is to allow the user to specify new drivers and to use them to make new connections. To do this I have this class:
public class DriverFinder extends URLClassLoader{
private JarFile jarFile = null;
private Vector drivers = new Vector();
public DriverFinder(String jarName) throws Exception{
super(new URL[]{ new URL("jar", "", "file:" + new File(jarName).getAbsolutePath() +"!/") }, ClassLoader.getSystemClassLoader());
jarFile = new JarFile(new File(jarName));
System.out.println("-->" + System.getProperty("java.class.path"));
System.setProperty("java.class.path", System.getProperty("java.class.path")+File.pathSeparator+jarName);
System.out.println("-->" + System.getProperty("java.class.path"));
Enumeration enumeration = jarFile.entries();
while(enumeration.hasMoreElements()){
String className = ((ZipEntry)enumeration.nextElement()).getName();
if(className.endsWith(".class")){
className = className.substring(0, className.length()-6);
if(className.indexOf("Driver")!=-1)System.out.println(className);
try{
Class classe = loadClass(className, true);
Class[] interfaces = classe.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces.getName().equals("java.sql.Driver")){
drivers.add(classe);
Class superclasse = classe.getSuperclass();
interfaces = superclasse.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces[i].getName().equals("java.sql.Driver")){
drivers.add(classe);
}catch(NoClassDefFoundError e){
}catch(Exception e){}
public Enumeration getDrivers(){
return drivers.elements();
public String getJarFileName(){
return jarFile.getName();
public static void main(String[] args) throws Exception{
DriverFinder df = new DriverFinder("D:/Classes/db2java.zip");
System.out.println("jar: " + df.getJarFileName());
Enumeration enumeration = df.getDrivers();
while(enumeration.hasMoreElements()){
Class classe = (Class)enumeration.nextElement();
System.out.println(classe.getName());
It loads a jar and searches it looking for drivers (classes implementing directly or indirectly interface java.sql.Driver) At the end of the execution I have found all drivers in the jar file.
The main application loads jar files from an XML file and instantiates one DriverFinder for each jar file. The problem is at execution time, it finds the drivers and i think loads it by issuing this statement (Class classe = loadClass(className, true);), but what i think is not what is happening... the execution of my code throws this exception

Unable to load prn file in LedgerLink

I am working with HE641 and having to use LedgerLink to load files since there is some account translation. For some reason I am unable to load the file. This is through Citrix. During the load process, the files appears to load because the status bar appears to increment upward but when I look at Data Entry in the app, I can not see any results. Cany anyone help me with this?

I had to get security to the translation file through Citrix.

How to dynamically load jar files - limiting scope to that thread

Dynamically loading jar files has been discussed a lot. I have read a quite a few posts, articles, and demo code for doing just that. However, I have yet to find a solution to my problem. Most people modify their system class loader and are happy. I have done that and was happy for a time. Occasionally, you will see reference to an application server or tomcat or some other large project that have successfully been able to load and unload jar files, allow for dynamic deployment of code, etc. However, I have not been able to achieve similar success; And my problem is much less complicated.
I have an application that executes a thread to send a given file/message to a standard JMS Server Queue. Depending on the parameters selected by the user, this thread may need to communicate with one of a number of JMS Servers, ie. JBoss, WebLogic, EAServer, Glassfish, etc. All of which can be done with the same code, but each needs to load their own flavor of JMS Client Jar files. In this instance, spawning a separate JVM for each communication would work from a classloader perspective. However, I need to keep it in the family and run under the same JVM, albeit each JMS Server Connection will be created and maintained in separate Threads.
I am close, I am doing the following...
1. Creating a new URLClassLoader in the run() method of each thread.
2. Set this threads contextClassLoader to the new URLClassLoader.
3. Load the javax.jms.JMSException class with the URLClassLoader.loadClass() method.
4. Create an initialContext object within this thread.
Note: I read that the initialContext and subsequent conext lookup calls would use the Thread�s
contextClassLoader for finding/loading classes.
5. Perform context.lookup calls for a connectionFactory and Queue name.
6. Create JMS Connection, etc. Send Message.
Most of this seems to work. However, I am still getting a NoClassDefFoundError exception for the javax.jms.JMSException class ( Note step #3 - tried to cure unsuccessfully).
If I include one of the JMS Client jar files ( ie wljmsclient.jar for weblogic ) in the classpath then it works for all the different JMS Servers, but I do not have confidence that each of the providers implemented these classes that now resolve the same way. It may work for now, but, I believe I am just lucky.
Can anyone shine some light on this for me and all the others who have wanted to dynamically load classes/jar files on a per Thread basis?

Thanks to everyone - I got it working!
First, BenSchulz' s dumpClassLoader() method helped me to visualize the classLoader hierarchy. I am still not completely sure I understand why my initial class was always found by the systemClassLoader, but knowning that - was the step I needed to find the solution.
Second, kdgregory suggested that I use a "glue class". I thought that I already was using a "glue class" because I did not have any JMSClient specific classes exposed to the rest of the application. They were all handled by my QueueAdmin class. However...
The real problem turned out to be that my two isolating classes (the parent "MessageSender", and the child "QueueAdmin") were contained within the same jar file that was included in the classpath. This meant that no matter what I did the classes were loaded by the systemClassLoader. Isolating them in classes was just the first step. I had to remove them from my jar file and create another jar file just for those JMSClient specific classes. Then this jar file was only included int custom classLoader that I created when I wanted to instantiate a JMSClient session.
I had to create an interface in the primary jar file that could be loaded by the systemClassLoader to provide the stubs for the individual methods that I needed to call in the MessageSender/QueueAdmin Classes. These JMSClient specific classes had to implement the interface so as to provide a relationship between the systemClassLoader classes and the custom classLoader classes.
Finally, when I loaded and instantiated the JMSClient specific classes with the custom classLoader I had to cast them to the interface class in order to make the method calls necessary to send the messages to the individual JMS Servers.
psuedu code/concept ....
Primary Jar File   - Included in ClassPath
Class<?> cls = ClassLoader.loadClass( "JMSClient.MessageSender" )
JMSClientInterface jmsClient = (JMSClientInterface) cls.newInstance()
jmsClient.sendMessage()
JMSClient Jar File - Loaded by Custom ClassLoader Only
MessageSender impliments Primary.JMSClientInterface{
    sendMessage() {
        Class<?> cls=ClassLoader.loadClass( "JMSClient.QueueAdmin" )
        QueueAdmin queueAdmin=(QueueAdmin) cls.newInstance()
        queueAdmin.JMSClientSpecificMethod()
    }

For doing this,First I am getting ClassLoader by using ClassLoader.getSystemClassLoader() and then type casting it to URLClassLoader.
But by doing it I am getting ClassCastException,because oc4j returns oracle.classloader.PolicyClassLoader instead of java.net.ClassLoader.
Appreciate if anyone can tell me how to load remote jar files using oracle.classloader.PolicyClassLoader .
Thanks
Harish

Hi,
I suppose you know about this, but just in case.
I have used jnpl to load jar files from remote location.

Anyone else having problems getting 4.5 files to open in 2008? I create a nice simple new xlf with a simple xls behind it and a just a grid component in 4.5, then try open the file in 2008 and i get... Crystal Xcelsius is unable to load this file. This file may be corrupt or have features that cannot be supported by this version of Crystal Xcelsius.im on the following versions...Version 4.5Application Version 4.2.4.3File Version 1.1.0.2Version 2008Application Version 5.0.0.99Build Number 12,0,0,121 I'm hoping that this is just a version issue with what was on ESD... the help file seem to suggest upgrade is simple so would but good to here of folks having sucess - and if so what versions your on thanks!jez.

well i hope thats the case... but its a bit strange that neither the beta versions i tested or this ESD version (its not very clear as to if its pre-release - nothing on the splashscreen/about to indicate its not the full thing) can open 4.5 files... suggests that the beta did not cover backward compatability which is a bit concerning :(hopefully im just missing something simple!from the help file in the '08 version i have here...Xcelsius supports the ability to import a visualization created
with Xcelsius 4.5. This import ability lets Xcelsius 4.5 customers upgrade their
existing visualizations to take advantage of the new features of Xcelsius 2008.
Backup your current XLF, JPEG, and external SWF files before upgrading your
visualization.
Note: Xcelsius 3.0, 3.5, and 4.0 files cannot be
imported into Xcelsius 2008. To use these files in Xcelsius 2008 you must first
import them into Xcelsius 4.5, then import the files into Xcelsius 2008.

Load jar file into Oracle db 10.1.0.2.0.

Hi,
I am trying to create a Java Stored procedure that is dependent on some other classes. The java source doesn't compile since it cannot find the imported libs.
How can I load jar files into the database so I can get my java source to compile?
I have heard of dbms_java.loadjava procedure, but not very clear on how to use it.
Please let me know how I can load the jar files in to the db.
Thanks,
-- DR.
