Loading Java classes in a script

I think I have this basic question:
I have a couple of Java classes that i want to call from a script.
I'm trying to use a scripting language in order to allow a simpler config interface to a user. Therefore this script will be something as simple as a wrapper on the classes already developed in java.
Any thoughts on how I should do this easily? (Scripting language, examples, ...)
Thanks!

To give a bit more of info, this is my java main:
package run;
import interfaces.Command;
public class test {
     public static void main(String[] args) {
          String classname = "instances.PingCmd";
          String parameter_file = "paramPing.xml";
          try {
               Command cmd = (Command) Class.forName(classname).newInstance();
               boolean rtn = cmd.execute(parameter_file);
               System.out.println("Test " + classname + ": " + rtn);
It calls various classes ("instances.PingCmd" in this example).
This is what I want my Groovy script to do. Just call some of these classes that I have made in java, and print the output.
Can anyone help me out with a similar example?
Thanks again!

How i load java class through javascript

Hi,
i want to load java class file at client side through the java script. Class file wich already at client side(client machine)
tell me is it possible....
thanks
plzz mail
[email protected]

From your post it is not very clear what you want to do.
1. Even if it was possible to load client classes using javascript, how on earth are you going to execute them ??? JavaScript and java are entirely different cups of tea.
2. If it was an applet, then probably you can access some classes from the client machine. Definely the default packages. However, I don't know whether you can access other classes. That might lead to a security issue. Please check with a java securities expart.
3. Loading a class from the client machine is DEFINITELY A BAD PROGRAMMING PRACTICE Use the codebase property on your applet tag to load the classes from the server.

OAAM 11g R2: Unable to load java class for custom configurable action

Need to configure a Configurable Action to get triggered for a particular action at a given checkpoint.
Steps Followed:
1. Created a java class implementing com.bharosa.vcrypt.tracker.dynamicactions.intf.DynamicAction, getParameters() and execute() methods were implemented in that java class.
2. Added necessary jars from $ORACLE_IDM_HOME\oaam\cli\lib to the build classpath.
3. Compiled and created a jar with it.
4. Extracted the oracle.oaam.extensions.war file into a working folder.
5. Added the Custom Jar created in step 3 into <working folder>/WEB-INF/lib/
6. Changed the following in MANIFEST.MF in <working folder>/META-INF/:
Specification-Version:11.1.2.0.1
Implementation-Version:11.1.2.0.1
7. Rejar-ed the oracle.oaam.extensions.war from the working folder using following command:
jar -cvfm oracle.oaam.extensions.war <working folder>\META-INF\MANIFEST.MF -C <working folder>/ .
8. Stopped the oaam_admin_server1, oaam_offline_server1 and oaam_server_server1.
9. Deleted the oracle.oaam.extensions deployment from the weblogic.
10. Deployed the newly created oracle.oaam.extensions as a shared library for oaam_admin_server1 and oaam_server_server1.
11. Started all managed servers.
But when I tried to create an action template with the java class I just created, it was throwing following error
+java.lang.ClassNotFoundException: *+
Unable to load configurable action class *. Ensure the class is made available in the class path.
Referred following documents:
1.      http://docs.oracle.com/cd/E27559_01/admin.1112/e27207/cfgactions.htm

This thread is a bit stale but I thought it might help to clarify one point about custom jar files on UCCX.
To properly load a custom jar:
Upload it into the classpath directory in the document repository.
Select it under System | Custom Classes Configuration
Finally you need to restart the CCX Engine and the CCX Administration services. If you have HA you need to restart them on both servers.
Other notes:
When referencing your class in the CCX Editor, use the fully qualified name of the class. Lots of other classes use things like Element or Document so you need to be explicit. The editor only knows about the 20 native classes by their object names. If you create a Document object in the editor you are really creating a com.cisco.doc.Document object. If you loaded jdom.jar and you wanted a jdom document then you need to create an object of type org.jdom.Document.
When compiling your custom jar files, be sure to compile for the version of Java that the CCX Engine runs. In general UCCX 7.X and older use Java 1.4. UCCX 8.X and higher use Java 1.6. Several of the core Java classes had significant changes between 1.4 and 1.6. If you ran your code on UCCX 7 or earlier and now it fails in UCCX 8.X or higher, recomplile for Java 1.6 and you classes will likely work again.
Finally, check for security violations in UCCX 8.X or higher. Cisco has restricted some of the things you can do. These URL's have more information:

Error while trying to load java classes

I am doing a 9iAS installation - at the end
of the installation I get an error stating
that the SSOHash class has not been loaded into the database. When I run the loadjava utility to load the class into the database
I get the following error:
ora-29545: badly formed class: user has
attempted to load a class (oracle.security.sso.SSOHash) into a restricted package. Permission can be granted by using dbms_java.grant_permission.
When I execute the dbms_java package I get
the following error:
ora-29532: classnotfoundexception
ora-06512: at "SYS.DBMS_JAVA", line 0
The install is being carried out on Solaris.
and the jdk version of the OS is 1.1. I read
in the oracle documentation that Oracle 8i
uses Java 2 compliance. Would it be a good
idea to upgrade the os jdk to 2.0 and do
a fresh install or are there workarounds.
Any help would be greatly appreciated.
Thanks,
Suzanne

This is a little late, but it sounds like you don't have the Java option installed on the database.

Hi,
Check whether the class is available in the schema or in the sys schema with a public synonym

Java.sql.sqlexception ora24344 error while trying to load Java class

Hi Guys,
I am getting "java.sql.sqlexception ora24344 error" while trying to load a java class using sql developer. Due to sensitivity of the code I am unable to post the code here but has anyone experienced a similar error before?
Thanks

Hi,
ora-24344 is known. It means it compiled but there are errors. Because you are not telling which version of Oracle you use, it is hard. Also you couldn't provide code will not make it easy. A common error is not having the right right on packages of SYS, such as UTL_* or DBMS_SYS_SQL. Can you maybe give the line of your code which produces the error?

Loading Java Class File in JSP page

I'm trying to load a java class file from a jsp page.
(e.g. MyFile.java <-- Source "MyFile.class<--Class file of MyFile.java")
jsp page
<%@ include file = "MyFile.class" %>
<HTML> // HTML Tags are here
MyFile.java
A normal java source file that has "public static void main" in it.
My jsp page can display it's contents, 'except' for showing e.g. "1235%%215648%%public%%$$@##" through out the page...
My guess is that it can't display my java class file..
Can anyone please help me solve this problem of mine ?

Can I load Java classes generated by the Web Service Proxy Wizard?

Hi gurus,
I am very new to Oracle JDeveloper and I have mainly used it to create and debug PL/SQL procedures. My client app is written in PowerBuilder 11 (Sybase), which claims that it will create a datawindow from a web service. Well, it turned out that PB can only handle simple stuff (it works with a very simple wsdl from the internet) but can't handle more complex ones that we need to use. So I am thinking about using JDev to create the web service proxy for the web service and then load it into Oracle as a Java stored procedure so that PowerBuilder can call the procedure. JDev succsfully generated the proxy and a few Java classes. My question is, do I need to load all the classes into the database? If yes, will the reference to the package work? For example, in a JDev generated class (the soap client class), it has package MyJdev.proxy; at the top. Or, will it work if I load all the classes included in package /MyJdev/proxy into the database?
Thank you very much for any help.
Ben

Thanks again, Bruce.
What I meant by SOAPElement is that one genereated Java class has this and this class also has the setter for this like this,
public void setSelection(javax.xml.soap.SOAPElement selection) {
this.selection = selection;
And here is the whole class,
public class CaseSearchByPartyRequest implements java.io.Serializable {
protected java.lang.String schemaVersion;
protected java.util.Calendar messageProducedDateTime;
protected javax.xml.soap.SOAPElement selection;
protected Restriction restriction;
public CaseSearchByPartyRequest() {
public java.lang.String getSchemaVersion() {
return schemaVersion;
public void setSchemaVersion(java.lang.String schemaVersion) {
this.schemaVersion = schemaVersion;
public java.util.Calendar getMessageProducedDateTime() {
return messageProducedDateTime;
public void setMessageProducedDateTime(java.util.Calendar messageProducedDateTime) {
this.messageProducedDateTime = messageProducedDateTime;
public javax.xml.soap.SOAPElement getSelection() {
return selection;
public void setSelection(javax.xml.soap.SOAPElement selection) {
this.selection = selection;
public Restriction getRestriction() {
return restriction;
public void setRestriction(Restriction restriction) {
this.restriction = restriction;
this.selection is the request that I think I need. And here is the static main method of the soap client class genereated.
public static void main(String[] args) {
try {
MyJdev.proxy.SoapClient myPort = new MyJdev.proxy.SoapClient();
System.out.println("calling " + myPort.getEndpoint());
// Add your own code here
} catch (Exception ex) {
ex.printStackTrace();
So, if I need to send the request to the web service, do I need to create the request, correct? I have done it through AQ and Messaging Gateway and works fine by manually creating the request xml in PL/SQL, but now I need to get it to work sychronously from the UI. I believe that I need the request (SOAPElement) because that is the only way that I can supply the parameters. I have not see any setters for the parameters other than some setters for user name and password.
Did I get something wrong here? If I don't supply the "selection", will JDev do it?
Thanks.
Ben

Unable to load Java classes from byte arrays.

I have an application started through JWS. It works fine except for one problem. The application allows the user to load an external class, typically received over a socket. These are not (and cannot) be signed. My application complains about not being able to load these when starting through JWS. When starting the application locally (i.e., run the jar file using 'java -jar APP.jar') it works fine.
I guess I have to grant som additional permissions in my policy-file. But since these classes are user-defined, there is no way for me to define a static codebase. `
Any ideas?

Java Web Start installs a SecurityManager, and after that is responsible for assigning permission collections to any code loaded by the JNLPCLassLoader.
If you have all-permissions for your jnlp loaded code, then use another ClassLoader to load some other code, That other class loader will assign the permissions to that code. If that ClassLoader dosn't extend SecureClassLoader, the code will get only the default permissions.
You can fix this by
1.) Use a ClassLoader that extends SecureClassLoader, and override getPermissions(), or
2.) just call System.setSecurityManager(null), from the trusted code loaded by the JNLPCLassLoader.

Load java class from another directory

Hi. I am new to Java. I am trying to load a java object from a subdirectory. Is that possible? Thanks in advance!

Thanks for the quick reply!
I tried this:
set CLASSPATH =
Data;Application;Entertainment;MiniGames;
but it doesn't seem to work...
The actual subdirectory is
\Data\Application\Entertainment\MiniGames
I am new to Java, so please bear with me with my
stupidity... please advice again.
Thanks in advanceClasspath needs to contain the actual directory paths, not a relative path. So it should be something like .;c:\Data\Application\Entertainment\MiniGames

Gregory:
If you want to upload several Java classes in one script the solution is .sql file, for example:
set define ?
create or replace and compile java source named "my.Sleep" as
package my;
import java.lang.Thread;
public class Sleep {
public static void main(String []args) throws java.lang.InterruptedException {
if (args != null && args.length>0) {
int s = Integer.parseInt(args[0]);
Thread.sleep(s*1000);
} else
Thread.sleep(1000);
create or replace and compile java source named "my.App" as
package my;
public class App {
public static void main(String []args) throws java.lang.InterruptedException {
System.out.println(args[0]);
exit
Then the .sql file can be parsed using the SQLPlus, JDeveloper or SQLDeveloper tools.
