Is it possible to load additional JAR Files?

Hi,
I was wondering if it is possible to load JAR files into an existing application. That is, if i have already deployed a JAD file onto a phone and have it running, is it possible to load additional classes into this program to use with the current program?
This is because depending on user decisions, different classes are needed and having all of them at once will use to much memory.

No, it's not possible.

Is it possible to load rt.jar?

Hi! I need some classes found in JDK 1.3.1, is it possible to load rt.jar into Oracle 9i? I've tried with but there are lots of errors (I've even decompressed and zipped it again since I was told it could help). Any ideas?
Thanks!

Hi:
Which classes are you looking for inside rt.jar?
Oracle 9i is shipped with JDK 1.3.1 complaint JVM, so the standard JDK is already loaded into SYS's schema.
Before uploading any class in SYS first check if doesn't exist.
You can find any particular class by using (logged as SYS):
SELECT dbms_java.longname(object_name) cName
FROM user_objects
WHERE object_type = 'JAVA CLASS' AND status = 'VALID'
AND dbms_java.longname(object_name) like 'javax/sql/%';
If you upload classes which where created during OJVM installation may be you can break the DB or get inconsistent results.
Missing classes can be uploaded extracting the rt.jar in an empty directory, copying only the missing classes and creating a new rt-missing.jar file.
Best regards, Marcelo.

How to load a Jar file in the class path?

How to load a Jar file which contains class files, images, etc.. in the classpath without using URLClassLoader.

You don't "load" jars. If it's on the classpath, you can obtain individual resources from it using various methods on either Class or ClassLoader. Do you mean "how to add a jar to the classpath at runtime"? Can't be done without using a classloader, typically URLClassLoader or a subclass thereof. Why you want to not use the proven method is beyond me. Presumably because you don't understand classloading. In which case, forget it.

Error while loading the jar file using loadjava

Hi,
I'm trying to load a jar file in to a database through the loadjava utility. First time when i loaded a jar file it created few public synonyms with /'s. like /5b3d7f97_BeanInfoIndexer.
Now i want to drop these synonyms before i reload the jar file with loadjava.
If i use DROP PUBLIC SYNONYM /5b3d7f97_BeanInfoIndexer; it gives the following error...
ERROR at line 1:
ORA-00933: SQL command not properly ended
I wonder how to drop these synonyms. I have to drop all these synonyms to freshly load the jar file.
Thanks
Shiva

You can include the synonym names in double quotes in the drop synonym command. But it is not a good idea to drop the synonyms(which have been created by loadjava) using drop synonym command. Instead, you can use dropjava command which will automatically drop all the synonyms created by the loadjava command.

Problem while loading a jar file into database

Hi All,
We are using Oracle 8.1.5 in Solaris. When I try to load a jar file into the database by using loadjava it gives the following error
Error while processing jar cryptix32.jar
Exception java.io.IOException: Load Java is unable to handle compressed entries: cryptix/provider/Cryptix.class
loadjava: 1 errors
Can anybody suggest anything to overcome this. Thanks in advance.

Hi John,
Thanks for your help. I unpacked the jar and rhen re-jared it with -0 (uncompress ) option. The above error is gone. But I am getting another problem. I am getting the following error for all the classes except the property files.
Error while resolving class cryptix/cryptix/provider/cipher/Rijndael

But the class is there in the jar. I am able to load single individual classes. Can anybody help me in this matter. Thanks in advance.

Is it possible to load a dump file collected from sql server to orcle 10gR2

Hi..
As a part of data migration from legacy systems , we need to migrate only required tables from Sql server to Oracle 10gr2 .
At present client is telling that he will give it as dump file.
My question is , Is it possible to load the dump file collected from sql server to oracle 10gR2?
Thanks in advance ..

yes, it is.
Using for example SQL Developer Migration Workbench even allows you to create unload scripts for the desired SQL Server tables and it also creates the DDL scripts for you to create the Oracle tables similar to the SQL Server table AND it alows creates the SQL*Loader scripts that allow you to load the SQL Server generated dump file into the Oracle db.
Here the link:
http://www.oracle.com/technology/tech/migration/workbench/index_sqldev_omwb.html
If you do not want to use this utility, you can also use SQL*Loader to load the content of the SQL Server dump file into the Oracle database; but in this case you have to write the whole SQL*Loader control scripts on your own.

Hi,
Check whether the file is open? close the file and try to pull once again.
Fields are matching with the data source? check it once. it should be in sync with MData fields.
and may be the problem with data...I think some Extra permitted chars / lower case is there in flat file. this can be solved by RSKC

Possible to create a JAR file from within a java app?

Is it possible to create a jar file from within a java application?
Can it be done more elegantly than by spawning-off another
process with the Runtime and exec() portions of the api?
Thanks
Scott

Thanks! I was mislead by the API notes for java.util.jar:
The JarOutputStream class is used to write the contents
of a JAR file to any output stream.
I was looking for a class or method to make jar files.
Seems this is it ;)
Thanks

CLASSPATH issues on DOS/NT and loading of jar files

Hello all,
I have the following problem on running WebLogic 5.1 on
NT. The CLASSPATH is getting truncated after a certain number of
characters. I have a lot of third party jar files that I use in my
application. How do I overcome this problem ? I tried increasing my DOS
environment space by changing the default values in config.sys.
What are other alternatives ?
One idea that I have is to use URLClassLoader to load the jar files. I
am running a RMI based application and I need to load these jar files
before I load the RMI code. Where would I run this URLClassLoader code
? Is there some system startup class that can load jar files ?
Thanks,
Aswin.

Thanks for the reply. I much appreciate it. What about the other idea that I
had outlined-loading these jar files using a ClassLoader. Is that viable ?

You still will not be able to have a command line exceeding a certain size
(around 1k or so). That is a hardcoded limit somewhere inside the NT kernel
("kernel" being a poor term for the piece so named in NT ;-).

Jinit not loading webutil jar files

Hello,
Our Application Server has had webutil installed on it for quiet some time now. I am implementing a custom Banner Form that requires webutil functionality. Well the form is all set, but the webutil portion does not function correctly. I have been working with the designers of this application and they recommended I make sure that my archive_jini and archive parameters be set in the file /u01/app/oracle/product/10gASforms/10.1.2/forms/server/formsweb.cfg as follows:
archive_jini=banicons.jar,bannerui.jar,banspecial.jar,banorep.jar,frmall_jinit.jar,gwucustom.jar,frmwebutil.jar,jacob.jar
archive=banicons.jar,bannerui.jar,banspecial.jar,banorep.jar,frmall.jar,gwucustom.jar,frmwebutil.jar,jacob.jar
so I set these up as requested. When I look at my Java Console I only see the following load:
banicons.jar, bannerui.jar, banspecial.jar, banorep.jar and frmall_jinit.jar
I do not see gwucustom.jar, frmwebutil or jacob.jar load.
Is there something I am missing? Do I have to restart the Application Server?
Thank you much in advance for any guidance anyone can provide!
-Stan

I actually corrected this issue myself.
In the formsweb.cfg file I added these properties under the default section.
There is a section called jinit_pprd (My Pre-Production test server, I added these values under there and the .jar files are now loading.

Loading separate JAR files.

Hello.
I have an application that loads functionality from separate jar files so that the application has a "hot deploy" feature. This means that the application reloads a certain functionallity if a new jar is deployed to that folder. This also means that the jars containing this functionality must be in a separate forlder than the jars for the application framework, or the system would try to load this as a functionallity as well.
In my JNLP file, I load the whole application framework at startup, but none of the functionality jars as these are loaded after the application has logged the user in and so on. I use URLClassLoader to load the funtionality classes but in these classes, I import from the allready loaded framework, and the functionalities I try to load throw an excaption that they do not find the classes in the framework.
Any ideas as to how the externally loaded jars can find classes loaded into the framework? This works perfectly well when I don't use web start, so there must be some class loading issues I am not aware of.
Thank you.
-r

OK, I am making some progress, but now I have a different problem: Some of the framework for loading was written by someone else and I would really like access to the debug information it prints without having to rewrite a lot to print it all to files. Is there any way to get access to everything that is being printed on System.out from web start. Been looking around but I can't find anything on the subject.

URLClassLoader + dynamically loading signed jar files

I have an applet that does not know all of the jar files it will need to load at startup.
I would like to dynamically load these signed jar files using the URLClassLoader, however it does not recognize these jar files as being signed and I get java.security.AccessControlException: access denied errors.
Any suggestions?
Thanks!

Try this classloader for loading the jars, it should to the trick:
import java.net.URL;
import java.net.URLClassLoader;
import java.net.URLStreamHandlerFactory;
import java.security.AllPermission;
import java.security.CodeSource;
import java.security.PermissionCollection;
import java.security.Permissions;
public class AllPermissionsClassLoader extends URLClassLoader {
    public AllPermissionsClassLoader (URL[] urls) {
        super(urls);
    public AllPermissionsClassLoader (URL[] urls, ClassLoader parent) {
        super(urls, parent);
        System.out.println(parent);
    public AllPermissionsClassLoader (URL[] urls, ClassLoader parent, URLStreamHandlerFactory factory) {
        super(urls, parent, factory);
    protected PermissionCollection getPermissions (CodeSource codesource) {
        Permissions permissions = new Permissions();
        permissions.add(new AllPermission());
        return permissions;
}
