Permission Denied when calling a method from VB using WebLogic 8.1.2 JCOM

Hi,
We are calling an java/ejb methods from VB using WebLogic JCOM 8.1 SP2. But
using JCOM, we are getting a error Permission denied when called from VB. We think
that we should update pathch jintegra 2.0 or 2.1 in WebLogic 8.1.2 the to solve
this issue, because we faced the same problen "permission denied" when we used
JINTEGRA(third party software). Once we installed the JINTEGRA 2.1 it solved the
issue.
So, can anyone help on regard to this issue of "Permission denied" in WebLogic
JCOM 8.1 SP2.
Thanks & Regards
Raghu

I too am experiencing the jCOM error: "Run-time error '70': Permission Denied". The problem appears to be related to a Microsoft Security Patch KB835732 (MS04-011 which, as you indicated, has been fixed in J-Integra v2.1 (FYI, jCOM 8.1 is based on J-Integra 1.5.4, see J-Integra/jCOM versions.
Did you ever get a resolution concerning 8.1 SP2? 8.1 SP3 is available now but I don't see any mention of jCOM updates in the WebLogic 8.1 What's New documention. I can't immediately upgrade (trying to stay on same version as a few other developers I work with) but I am hoping it is resolved in SP3.

How to call a method by specific IP address(if the system has 2 IP address)

Hi All,
In my project I have two N220 systems, which has two IP addresses each. Server has the following IP addresses
172.31.128.93 This IP address connected thorugh HUB
3.3.3.1 This IP address connected through Crossover cable
Client has the following IP addresses
172.31.128.94 This IP address connected thorugh HUB
3.3.3.2 This IP address connected through Crossover cable
In server system I bind the RMI registry in the following way
Naming.rebind ("rmi://3.3.3.1/HeartBeat", this);
And in Client system I lookup in the following way
Naming.lookup("rmi://3.3.3.1:1099/HeartBeat");
Now the problem is, the method in RMI server is not called through Crossover link it is happening through TCP/IP link. Is there any way to call the method by only using Crossover link?
Please help me with this issue...
Thanks in advance.

Hi all,
In solaris 220 machine i am facing the following problem While executing lookup method.
If the crossover cable is properly connected lookup method is working fine.
If the crossover cable is unplugged, lookup method is waiting indefinitely until the cable is plugged in. (Lookup method is not throwing any exception )
Is there any way to avoid this ?
Please help me with this issue..
Thanks in advance...

Programmatically calling CreateInsert Method

Is it possible to call createInsert method programmatically,
My Use case is I am created a form When form load ineed to show a insert mode,;

in your page definition, you should add the createInsert to page bindings
<bindings>
    <action IterBinding="YourViewIterator" id="CreateInsert"
            RequiresUpdateModel="true" Action="createInsertRow"/>
</bindings>then you can call the createInsert in your bean using this method
    public BindingContainer getBindings() {
        return BindingContext.getCurrent().getCurrentBindingsEntry();
    public String callCreateInsert() {
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding = bindings.getOperationBinding("CreateInsert");
        Object result = operationBinding.execute();
        if (!operationBinding.getErrors().isEmpty()) {
            return null;
        return null;

How to call object method (eg, CallIntMethod)in C?

I aslo get problem when I use "CallIntMehtod", the following is my program
test.java
public class test {
public int getvalue(int n)
System.out.println("cjf, welcome");
return n*n;
invoke.c
#include <jni.h>
int main() {
int res;
JavaVM *jvm;
JNIEnv *env;
JavaVMInitArgs vm_args;
JavaVMOption options[3];
jclass cls;
jmethodID mid;
vm_args.version = JNI_VERSION_1_2;
vm_args.nOptions = 3;
// vm_args.options = options;
vm_args.ignoreUnrecognized = JNI_TRUE;
res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args); /* create VM */
if (res < 0) {
fprintf(stderr, "Can't create Java VM\n");
exit(1);
printf("success create java VM \n");
cls = (*env)->FindClass(env, "test");/* find class */
if ( cls != (jclass)0 ) {
mid = (*env)->GetMethodID( env, cls, "getvalue", "(I)I" );/* get method ID */
if( mid != 0 ){
printf("First call to Java returns:%d\n", (*env)->CallIntMethod(env, cls, mid,2) );/* execute
method */
(*jvm)->DestroyJavaVM(jvm);/* destroy java VM */
fprintf(stdout, "Java VM destory.\n");
return 0;
when I compiled them and run it, I cann't get the expected result. the result is:
nspws1@/home/bss>./invoke
success create java VM
First call to Java returns:0
Java VM destory.
so ,what' wrong?

Your method "getvalue" is not static.
You have to create an object of your class "test" and call the method with this object (not with the class) as parameter: CallIntMethod(env, obj, mid,2).

AutomationException while calling a method

Hi all,
I've got a problem accessing a COM/DCOM component in a Win2k box (Advanced Server)
with jcom. I configured the server and client described in the "JSP to COM" example.
The only difference: I don't want to access the excel sheet and I don't use a jsp
to execute.
I used the java2com.exe to create the proxies from my dll ScriptableUniversalTransAgt.dll.
But when I try to call a method on the dll via Java, I get the exception:

Generically calling a method on an object

Hello,
I am trying to write a small utility method to generically call a method on an object.
This is what I have.
    public static void doCall(Object o, String methodName, Object ... args){
        Class[] types = new Class[args.length];
        int i = 0;
        for(Object arg : args){
            types[i] = arg.getClass();
        try {
            Method m = o.getClass().getMethod(methodName, types);
            m.invoke(o, args);
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("Error dynamically calling method " + methodName + " on " + o.toString());
    }It doesn't work because it can't find the method. If I hard code the parameter types as "new Object[] {Double.TYPE}" it works fine (on methods that take a double).
So, my question is, how can I generically set up the parameter types based on the types of the arguments?
Thanks,
~Eric

The problem is not on calling agr.getClass(), your primitive double is already autoboxed to a Double object. It is the doCall(...) method who expects an object, not a primitive. So when giving it a primitive value, java autoboxes it to the corresponding object type.
This means your attempt will only work if the methods to call do not have any primitives as parameters.
Test this code:
public class GenericMethodCaller {
     public static void doCall(Object o, String methodName, Object ... args){
        Class[] types = new Class[args.length];
        int i = 0;
        for(Object arg : args){
            types[i++] = arg.getClass();
        try {
            Method m = o.getClass().getMethod(methodName, types);
            m.invoke(o, args);
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("Error dynamically calling method " + methodName + " on " + o.toString());
     public static void main(String[] args) {
          Callable callee = new Callable();
          callee.callabelMethod(10d);
          GenericMethodCaller.doCall( callee, "callabelMethod", 10d ); // 10d gets autoboxed to a Double object.
class Callable {
     public void callabelMethod(Double o) {
          System.out.println("callabelMethod(Double o) called");
     public void callabelMethod(double o) {
          System.out.println("callabelMethod(double o) called");
}The output will be:
callabelMethod(double o) called
callabelMethod(Double o) called

Calling a method on backing bean in response to contextual event

Hi
I am using Jdeveloper 11.1.1.6.0 and using ADF contextual events..
I have a drop down list and i am rasiing a contextual event on changing the current selection. In response to that event i want to call a backing bean method with parameters.. But when i click on the subscriber section for the contextual event, i can see only some bindings of the page.. How can i call a method on backing bean as a subscriber..
Thanks
Raghu

Hi,
this article has a use case for the POJO approach: http://www.oracle.com/technetwork/issue-archive/2011/11-may/o31adf-352561.html
Another is to define a method binding in the receiving PageDef file and configure it as explained here

Any way (event) to call Java method after view created in JSF 2.0

Hi,
I am using JSF 2.0 Mojarra's implementation.
I am interested to know if there is a way to call Java methods before and/or after view has been restored.
I wanted to initialize data for my page in this Java method.
I could see there is an event class PostRestoreStateEvent added in JSF 2.0. How to use it?
I tired to use f:event element as below, but it does not work. Can anyone share anyother idea to achieve this behaviour?
<f:metadata>
<f:event type="postRestoreState" listener="#{employeeLoadBean.loadAfterRestoreView}"/>
</f:metadata>
Regards,
Kishore K S

Hi,
The problem is solved as below.
<f:metadata>
<f:event type="javax.faces.event.PostRestoreStateEvent" listener="#{employeeViewEventListener.postRestoreState}"/>
</f:metadata>
The above calls the Java method #{employeeViewEventListener.postRestoreState} whenever View has been restored.
It was not working when shortName of the event (ie., postRestoreState) is given and throwing ClassNotFound exception.

Kishore K S

Hi,
When you use the database value directly in your BDC, you will have this issue. It is always advisable to use character fields when doing BDC. so change it to charecter field and try it..

How to call a method in one JSP from another JSP?

say that I have 2 JSPs.
JSP one has a button.
JSP two has some method that, say, find the square root of the number passed from JPS one.
How to - when click - the button on page one call the method on page two?
Please note that I can not use object binding, but I want passing the actual parameter and call the method on page two.
Please note that this is an update of a previous post on the same topic called "Object scope".
Thank you all very much.

No, i dont know how to call other than main methods from other classes
And one more doubt i have i.e. Like in C can we see the execution of the program like how the code is being compiled step by step and how the value of the variable changes from step to step like(Add Watch).........

Is it possible to call a method in a servlet from a java script ?

I need to do a dynamic html page . In the page i select some things and then these things must communicate whit a servlet because the servlet will do some DB querys and update the same webpage.
So is it possible to actually call a method of a servlet from a java script? i want to do something that looks like this page:
http://www.hebdo.net/v5/search/search.asp?rubno=4000&cregion=1011&sid=69DHOTQ30307151
So when u select something in the first list the secodn list automaticly updates.
thank you very much

You can
1. load all the options when loading the page and
set second selection options when user selected
the first; or
2. reload the page when user select first selection
by 'onChange' event; or
3. using iframe so you only need to reload part of
the page.

I cann't call a method if it use HttpServletRequest as a parameter
