LOADJAVA hangs loading JAR

Hi everyone!
I am trying to load 2 JAR files into an Oracle 9.2.0.4 database (running on Windows2000 Server) using LOADJAVA. The JAR's are supplied by IBM for their WebSphere MQ (release 5.3) product. One of the two JAR files loads and resolves without a problem, using the following command:
loadjava -user mqseries/mqseries@lamp_pit12dv17 -fileout d:\newpumps\loadjava.log -grant lamp -genmissingjar d:\newpumps\connector-missing.jar -resolve connector.jar
LOADJAVA hangs, however, when attempting to load the other JAR. Here is the command I'm using:
loadjava -user mqseries/mqseries@lamp_pit12dv17 -fileout d:\newpumps\loadjava.log -grant lamp -genmissingjar d:\newpumps\com-missing.jar -resolve -force com.ibm.mq.jar
The second LOADJAVA invocation is the same as the first, except for the argument to "-genmissingjar", the addition of "-force", and the target jar file. Running LOADJAVA without the "-force" switch yields the same result: a hung session.
If I add the "-verbose" option, I get the following output:
arguments: '-user' 'mqseries/mqseries@lamp_pit12dv17' '-fileout' 'd:\newpumps\loadjava.log' '-genmissingjar' 'd:\newpumps\com-missing.jar' '-resolve' '-force' '-verbose' 'com.ibm.mq.jar'
creating : resource META-INF/MANIFEST.MF
loading : resource META-INF/MANIFEST.MF
genmissing: com/ibm/mq/BatchMatchingCriteria
creating : class com/ibm/mq/BatchMatchingCriteria
loading : class com/ibm/mq/BatchMatchingCriteria
If I use OEM to examine the suspended LOADJAVA session, I find it is attempting to execute 'alter java class "com/ibm/mq/BatchMatchingCriteria" compile". This class happens to be the first class in alpabetical order in the JAR.
I've also tried running LOADJAVA without the "-resolve" switch. When I do, both JAR files load into the database; however, all their classes are marked invalid. Attempting to compile any class in the com.ibm.mq.jar file also results in a suspended session.
I'd greatly appreciate any suggestions for getting past this problem. Is there something about the Java environment in my 9i database that is missing? What would cause LOADJAVA to hang?

Does Java otherwise work? Are the system Java classes valid? Try running:
select count(*) from all_objects where OBJECT_TYPE like 'JAVA CLASS';
this should be in the thousands
select count(*) from all_objects where OBJECT_TYPE like 'JAVA CLASS' AND STATUS like 'INVALID';
I think this should be zero, or near-zero.

Loadjava to load jar file.

hi all,
i created a jar file 'hello.jar' with the contents as 'hello/HelloName.class'
here, hello is the package and HelloName.class is a Java Class.
the jar i created with un-compression mode. so the Class file size is same in jar file and out side of jar.
i tried to load the jar using, loadjava, here is the syntax.
bash-3.00$ loadjava -u user/password -v /export/home/oracle/javaSrc/hello.jar
arguments: '-u' 'spboardv2/***' '-v' '/export/home/oracle/javaSrc/hello.jar'

it seems no errors.
when i checked in USER_OBJECTS table,
i found the record 'hello/HelloName' as OBJECT_NAME but the STATUS is 'INVALID'.
Please help me how to get this.
thanks in advance.

Hi,
got the solution for this.
in loadjava options, there is an option '-r' or '-resolve'.
if we used this option for loading .java file, the source will get compiled and Class file will be resolved and stored in Oracle.
if we used this option for .class file or for .jar file, the class file will be resolved and stored in Oracle.
loadjava -u scott/tiger -r path/Hello.class
loadjava -u scott/tiger -r path/hello.jar
Here, resolving means, it will check each and Class file(s), for all imports. If all other Classes exists in CLASSPATH, it will load the class and the STATUS is VALID. if it failed to load any imports, the status is INVALID and means, need to set CLASSPATH.
now, i'm struggling how to set CLASSPATH for loadjava.

pavan.

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

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()
    }

How to load jar files from remote location

Hi all,
I am trying to load jar files from remote server, from a servlet which is running on OC4j.
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.

Ive just learned that i can use loadjava to load jsp pages into the database.

Ive just learned that i can use loadjava to load jsp pages into the database. How is that possible. How can someone go to my lets say, index.jsp page and actually see it if its inside the database? What authenticates it? Where would you set the parameters to tell http(apache) to look inside the db for the pages?
Any ideas?

Thanks for the reply. If I put the file on the database, does it have to be in a particular location? I've put it on the database server, launched sql*plus (as APPS) and ran the following:
execute dbms_java.loadjava('-v', 'ZebraGetPrinterFromXML.class');
PL/SQL procedure successfully completed.Then when I try to run a process that uses this I get this:
ORA-29540: class ZebraGetPrinterFromXML does not exist
