How to invoke action method from mail contained link

Hello,
my application needs to send mails to users that include links for the user to click on. Something like www.mysite.com/displayData.jsp&id=123. My question is now how I make JSF invoke the respective method in the backed bean to display the data with the id 123 when the user clicks on the link int the mail.
I wonder whether there is some kind of "catch-all action" that checks whether the user is logged in and authorized whenever any JSP page is invoked. I'm a bit tired of first checking the authorization of some user before processing the remaining part od the backed bean's action method.
Thanks for any hints,
Oliver Plohmann

How to invoke Java method from C++

Hi
My requirement is In C++ we are having three different structures, like
struct one{
int accontno;
char * accountholdername;
long balance;
struct two{
int startdate;
int enddate;
struct three{
char* userid;
char* userpassword;
from c++ how to pass these structures, these structures I have to read in Java class, and in java how receive these structures.
And the sample methods will be like: getCarsData(Input, output, Error);
How do i call the method in JNI, if it is static int method we can call like
getStaticIntMethodID(), instead of int if i have to pass the above mentioned structures how do i do? Should i create an object array in JNI for accessing these three structures?
Suggestions/Samples welcome
Thanks,

Why did you start another thread for this?
I was answering you in the [url http://forum.java.sun.com/thread.jspa?threadID=712137&messageID=4119725#4119725]old thread and you didn't even bother to answer back my (basic) questions.
I told you to use the code tags when pasting code. Got ignored. I also gave you a starting example on how to achieve your goal. Flushed.
Oh well, I'm getting used to it.
Again.
Before starting, allways keep near you the [url http://java.sun.com/j2se/1.5.0/docs/guide/jni/spec/jniTOC.html]JNI reference. All the JNI functions are documented in it.
First you need to create custom Java classes that will match the C++ stucts (remember?).
There is no magic wand in JNI that will transform the C++ structs into the custom Java classes and vice versa.
You'll have to code it by hand, one field at a time. It's a pain.
So for the one, two, three C++ structs (why not posting some real names instead of this crap?),
there will be JOne, JTwo and JThree Java classes.
There is also that other Java class already existing with getCarsData() static method that will fetch the data.
And finally the DLL function wich will call this Java static method, doing the bridge between the C++ structs and the custom Java classes, finally return the data.
Due to the lack of explanation from your posts, I will say that the getCarsData() static method receives a parameter of type JOne
and returns an array of JTwo objects.
So the get_cars_data() DLL function receives a parameter which is a struct one and
returns a pointer to an array of struct two elements.
// C++ structs
struct one {
    int accontno;
    char * accountholdername;
    long balance;
struct two {
    int startdate;
    int enddate;
struct three {
    char * userid;
    char * userpassword;
// custom Java classes
class JOne {
    int accontno;
    String accountholdername;
    int balance;
class JTwo {
    int startdate;
    int enddate;
class JThree {
    String userid;
    String userpassword;
// Java class with static method that gets the data
class DataFetcher {
    static JTwo[] getCarsData(JOne one) {
// DLL function
// struct 'one' parameter is already filled with values.
// Returns an array of 'two' C++ struct obtained from a Java static method
two * get_cars_data(one o) {
    JNIEnv * env;
    /** not show here is the code to either
        create the JVM or
        attach it to the current thread **/
    // get the data from 'one' C++ struct and put it in a new instance of JOne Java class
    jclass oneCls = env->FindClass("JOne");
    jmethodID oneCtorID = env->GetMethodID(oneCls, "<init>", "()V");
    jfieldID accontnoID = env->GetFieldID(oneCls, "accontno", "I");
    jfieldID accountholdernameID = env->GetFieldID(oneCls, "accountholdername", "Ljava/lang/String;");
    jfieldID balanceID = env->GetFieldID(oneCls, "balance", "I");
    jobject oneObj = env->NewObject(oneCls, oneCtorID);
    env->SetIntField(oneObj, accontnoID, o.accontno);
    env->SetObjectField(oneObj, accountholdernameID, env->NewStringUTF((const char *)o.accountholdername));
    env->SetIntField(oneObj, balanceID, o.balanceo);
    // call the Java static method
    jclass dfCls = env->FindClass("DataFetcher");
    jmethodID getCarsDataID = env->GetStaticMethodID(dfCls, "getCarsData", "(LJOne;)[LJTwo;");
    jobjectarray twoArray = (jobjectarray)env->CallStaticObjectMethod(dfCls, getCarsDataID, oneObj);
    // create the 'two' C++ struct array from the Java array of JTwo objects
    jclass twoCls = env->FindClass("JTwo");
    jfieldID startdateID = env->GetFieldID(twoCls, "startdate", "I");
    jfieldID enddateID = env->GetFieldID(twoCls, "enddate", "I");
    jint len = env->GetArrayLength(twoArray);
    two * pt = new two[len];
    for (int i = 0; i < len; i++) {
        jobject twoObj = env->GetObjectArrayElement(twoArray, i);
        pt.startdate = env->GetIntField(twoObj, startdateID);
pt[i].enddate = env->GetIntField(twoObj, enddateID);
// return the resulting 'two' C++ struct array
return pt;

Invoke beanshell methods from java

Hello
I'm learning beanshell and using it to write scripts that are ran in JDK 6.
My question is how to invok beanshell methods from java source codes.
My codes is:
import javax.script.*;
public class InvokeFunctions {
public static void main (String[] args)throws ScriptException, NoSuchMethodException
ScriptEngineManager sem = new ScriptEngineManager();
ScriptEngine bshEngine = sem.getEngineByName("beanshell");
String script = "public void sayHello()"+"{print (\"sayHello() is a method in bsh script\");}";
bshEngine.eval(script);
Invocable inbshEngine = (Invocable)bshEngine;
inbshEngine.invokeFunction("sayHello");
I defined a method "sayHello()" using beanshell, but i just can't invoke it in Java.
I got an error msg said:
Exception in thread "main" java.lang.IllegalAccessError: tried to access method bsh.NameSpace.getThis(Lbsh/Interpreter;)Lbsh/This; from class bsh.engine.BshScriptEngine
Any one has any idea about it?
Thanks

Look at the Javadoc documentation of IllegalAccessError. It says:
Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to.
Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.
Maybe recompiling all your sources (make sure you delete all existing *.class files) will help?

How to invoke action or script from html wiget in Adobe Configurator?
Please help! I tried to make it about 5 hours!
I need something like that:
I click link or image
...and it runs action.
Thanks!

If you click on the question mark ( as shown below) on the right of Configurator 2 window

Anyway once you have your action or script button in your panel you must select it and configure it in the inspector palette

Invoking java methods from C/C++ on the machine with different JREs

I implemented Windows NT Service instantiating JVM and invoking several java methods. Everything works but I have an issue with running the service on the machine where multiple different versions of JRE have been installed. The service is calling java methods that require JRE 1.3 or later so I wrote the code that is setting system PATH from within the service based on the configuration stored in the external file. The problem is that the service requires jvm.dll to be in the PATH prior lunching it since this library is instantiated through the implicit linking. When I put jvm.dll in the same path as the service binary I can lunch it but JNI_CreateJavaVM fails and returns -1. This happens even if JRE 1.3 is in the system PATH prior lunching the service.
Everything works if the system PATH contains references to JRE 1.3 and jvm.dll is removed from the service's directory.
I am looking for an advice on what is the proper way to deal with invoking java methods from the C/C++ executable in the environment with different versions of JRE.
Thanks, Kris.

Here's a way I have done what you are asking about:
What you want to do is make all of your linking happen at runtime, rather than at compile time. This way, you can edit the PATH variable before the jvm.dll gets loaded.
Following is some code that I used to handle a dll of my own in this manner. You can decide if you want to write a "wrapper" dll, or if you find it simpler to approach the jvm.dll in this way.
// Define pointer type for DLL entry point.
     typedef void JREPDLL_API (*EXECUTEREQUEST)(char*, Arguments&);
// Set up path, load dll, and pass everything off to it.
HINSTANCE javaServer = javaServer = LoadLibrary("jrepdll.dll");
if (javaServer != NULL) {
EXECUTEREQUEST executeRequest = (EXECUTEREQUEST)GetProcAddress(javaServer, "ExecuteRequest");
if (executeRequest != NULL) {
if (argc == 1)
     // Execute the request.
     executeRequest("-run", args);
else
     // Execute the request.
     executeRequest("-console", args);
Here's some code for how to edit the PATH:
          // Edit the PATH environment variable so that we use our private java.
char *appendPt;
char *newPath;
char *path;
          char tmp[_MAX_PATH];
          // Get the current PATH variable setting.
path = getenv("PATH");
          // Allocate space for an edited path setting.
          if (path != NULL)
               newPath = (char*)malloc((_MAX_PATH * 2) + strlen(path));
          else
               newPath = (char*)malloc((_MAX_PATH * 2));
          // Get upper part of path to desired directories.
          strcpy(tmp, filepath);
          appendPt = strstr(tmp, "dbin\\jreplicator");
          appendPt[0] = '\0';
sprintf(newPath, "PATH=%sjava\\jre1.2.2\\bin;%sjava\\jre1.2.2\\bin\\classic", tmp, tmp);
// Append the value of the existing PATH environment variable.
// If there is anything, append it.
if (path != NULL) {
     strcat(newPath, ";");
     strncat(newPath, path, (sizeof(newPath) - strlen(newPath) - 2));
// Set new PATH value.
_putenv(newPath);
          free(newPath);

Is it possible to invoke JEB method from thread?

Hello everybody!
I have problem creating EJB from the thread. Here is the part of code below:
public void email() throws Exception {
class MailThread implements Runnable {
public MailThread() {
public void run() {
try {
String jndiName "java:comp/env/ejb/PROG/Mail";
IMailHome mailHome;
IMail mail;
InitialContext context = new InitialContext();
Object objref = context.lookup(jndiName);
mailHome = (IMailHome) PortableRemoteObject.narrow(objref, IMailHome.class);
// Exception here:
// java.rmi.RemoteException: Exception Substitute; nested exception is:
// java.lang.NullPointerException mail = mailHome.create();
// business metods
// mail.method1();
} catch (Exception e) {
System.out.println("Exception:" + e);
MailThread mt = new MailThread();
Thread thread = new Thread(mt);
thread.start();
Exception:
java.rmi.RemoteException: Exception Substitute; nested exception is:
java.lang.NullPointerException
I am not able to create EJB instance from the thread. The same code works well in servlet. Am I doing something wrong?
May be there are some different approaches to implement some operations asynchronously at EJB level do not using JMS and MDB? J2EE specification prohibits to use threads inside EJB so the only way I see is to create different thread on servlet side and invoke EJB methods from it. But it seems that this doesn't work too. Could anyone help me?
Thanks in advance,
Vadim Lotarev

If the passcode will not work, the only alternative is to restore the phone as new. You cannot change the passcode from the lock screen.

Question on "How-to invoke a method once upon application start"

Hello everyone.
I'm trying to implement what the article "How-to invoke a method once upon application start" by Frank suggests.
https://blogs.oracle.com/jdevotnharvest/entry/how_to_invoke_a_method
Suppose that I'm having a single point of entry, so in my login.jpsx I have the below:
<f:view beforePhase="#{login.onBeforePhase}">In the method "onBeforePhase" I have to pass the phaseEvent, since the signature is the following:
public void onBeforePhase(PhaseEvent phaseEvent)but how do I know the phaseEvent when calling the login.onBeforePhase? How the call should be?
Thanks a lot!
ps. I'm using jDev 11.1.2.1.0

You need not pass anything to this method , this method will get called before every Phase except ReStore View
Just write the logic as Frank suggested for the phase in which you want the code to execute. You can get the PhaseId's like
PhaseId.RENDER_RESPONSE
public void onBeforePhase(PhaseEvent phaseEvent) {// from Frank's doc
//render response is called on an initial page request
if(phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE){
... etc

How to invoke crystal reports from Oracle forms 11g R2 along with passing p

How to invoke crystal reports from Oracle forms 11g R2 along with passing parameter to it.
how to pass parameters to crystal report, please help.

how to pass parameters to crystal report, please help.This would entirely depend on crystal reports and you might find informations on crystal reports related communities more likely...I for one have seen crystal reports the last time about 12 years ago. And even back then I simply acknowledged it's existence instead of working with it.
Maybe crystal reports can be invoked via a URL call which would make it simple as you'd need simply build an URL and show the report using web.show_document. But that's pure speculation. Also you might not be the first with this requirement, so the solution to your problem might be right under your nose and just a little google search away ;)

How to call java method from workflow script?

Hi
I have a requirement of updating field value 'Document Status' based on review/approve of content from Workflow and hence need to update the version number. For that I need to call my java method from workflow during submit of review/approve condition. Please let me know how to call java method from workflow?
Is there any alternative better way to achive this requirement from workflow? Please suggest.
Thanks,
Sarang

OK. So, I think we can all conclude that you don't need to call any Java method, can't we? And, that wfUpdateMetadata is the command that will update your metadata.
Now, the question is what are its arguments. It has two - the first is the name of a custom metadata field to be updated (let's suppose that one field is called xMinorVersion, and the other xMajorVersion), the other is the new value, e.g. <$wfUpdateMetaData("xMinorVersion", "New value.")$>As for new value - do you insist on using strings? Since you want to increase the value, it would be more convenient to work with numbers. For instance, with integers you could go with <$wfUpdateMetaData("xMinorVersion", xMinorVersion + 1)$>With strings you will need to convert it to numbers and back to strings. Besides, what happens if you have more than 100 minor versions? (you mentioned you want to add 0.01, but that would finally increase the major version, wouldn't it?) So, I think these two numbers are independent (perhaps, with exception that increase on the major version set the minor version to .00).
If you want to present it, you can use profiles that will construct for you the representation 2.304 out of MajorVersion = 2, MinorVersion = 304
Solved?
