How to run jscript or vbscript inside a java class

I would like to create a class that can excecute jscripts and/or Vbscripts. Does any one knows if there is a class or a way to host jscrips so the script can access only the methods I specify in my "hosting env"? This is similar as using MS scripting utility to run vbscripts inside a VBprogram.
Thanks

How to run a openssl command from a java program

Hi All
Please suggest on how to run a openssl command from a java program.
I am using this
Runtime runtime = Runtime.getRuntime();
runtime.exec("openssl pkcs8 -inform der -nocrypt test.der result.pem");
This is suppose to take test.der as input and create result.pem.
There are no errors but the file result.pem isnt created.
Thanks in Advance

First off is that openssl command correct? Should it be this instead:
openssl pkcs8 -inform der -nocrypt -in test.der -out result.pem
Try out your openssl command within a command prompt so that you know that it works ok. I think the command line you specified waits on stdin (well it does for me).
After that.....
runtime.exec creates a Process object. If you do this:
Process openssl = runtime.exec("....")
then you can examine the return code from openssl to see the exit code - for instance if the input file does not exist then exit = 1. You can test for this with Java
Alternatively you could get the stderr from the process and look inside it - if it is 0 length then all is good, if it has some text in there then it has likely failed. You could then throw an exception and include the stderr output in the exception messgae. You may need to experiment with this, runnig it first when openssl is happy then running it again when openssl is upset.

How to get the status of Javascript inside a java class

Hi,
Can anybody let me know the way by which I can get the status of Javascript (enabled/disabled) in browser inside a Java Class.
I do have a trick -
<input type="hidden" name="jstatus" value="disabled">
<input type="submit" name="submit" onClick="doChecking()">
<script language= javascript>
function doChecking()
document.form.jstatus.value = "enabled";
submit();
Now inside our java class we can check the value of "jstatus" if it is disabled then it is disabled else it is enabled.
Ha ha wat a stupid trick...... ;-)
Plz let me know a real approach to determine the Javascript status.
Cheers !!!
Irshad

Actually, I don't think that trick is stupid at all. Javascript and Java are normally in no way related (javascript is just plain text content to your servlets / jsp's). So a good way of getting such information to your server is submitting it, like you do.
Another possibility would be to do it with Ajax in the background, but that all depends on what you do with the information.

How to get the profile object in simple java class (Property accessor)

Hi All,
Please guide me how to get the profile object in simple java class (Property accessor) which is extending the RepositoryPropertyDescriptor.
I have one requirement where i need the profile object i.e i have store id which is tied to profile .so i need the profile object in the property accessor of the SKU item descriptor property, which is extending RepositoryPropertyDescriptor.
a.I dont have request object also to do request.resolvename.
b.It is not a component to create setter and getter.It is simple java class which is extending the RepositoryPropertyDescriptor.
Advance Thanks.

Iam afraid you might run into synchronization issues with it. You are trying to get/set value of property of a sku repository item that is shared across various profiles.
Say one profile A called setPropertyValue("propertyName", value).Now another profile B accesses
getPropertyValue() {
super.getPropertyValue() // Chance of getting value set by Profile A.
// Perform logic
There is a chance that profile B getting the value set by Profile A and hence inconsistency.
How about doing this way??
Create PropertyDescriptor in Profile (i.e user item descriptor), pass the attribute CustomCatalogTools in userProfile.xml to that property.
<attribute name="catalogTools" value="atg.commerce.catalog.CustomCatalogTools"/>
getPropertyValue()
//You have Profile item descriptor and also storeId property value.
// Use CustomCatalogTools.findSku();
// Use storeId, profile repository item, sku repository item to perform the logic
Here user itemdescriptor getPropertyValue/setPropertyValue is always called by same profile and there is consistency.

Call apt inside a java class

Hi all,
Is it possible to call the Annotation Processing Tool inside a Java class ?
If yes, how to perform this call ?
Thanks.
Micka�l

Hello Micka�l,
Here is a test class for one of my apt processors.
https://rapt.dev.java.net/source/browse/rapt/test/net/java/dev/rapt/exploratory/mixin/TestMixins.java?rev=1.1&view=markup
The code to call apt is in the last method called "runApt". Note that this method takes the source code to be compiled as a String and writes it to a file, but YOU may not want to do that.
Oh, and if you try to understand the rest of the code, there is lots of source inside javadoc comments. Basically, each @LongString static String is initialized to the value of its javadoc comment. Which is cool for writing tests but really confusing if you are not aware of what is happening - and I was hoping to help you, not confuse you :)

How to get access to PageContext in a java class (.java file)?

Hi all,
I am trying to get access to PageContext from inside a java class, and it doesn't seem to work.
I could get the PageContext from a jsp page, at the object instantiation, through the constructor, but my class is not called by a jsp page.
Any ideas?
Thanks,
Paul

Basically I do not need to change any attributes from pageContext. However I need the pageContext object because I am using a third party component that is initialized with the pageContext .
I cannot change the implementation of that component: it is a black box to me, I simply need the pageContext in my java class that uses the component.
Any thoughts based on this clarification?
Thanks,
Paul

Help! How to read a .txt file into a Java class and make 2D array?

Hi guys,
Im a newbie with arrays, just started really using them.. please bear with me if I don't seem to understand much..
I have a .txt file that contains either a square or rectangle (random width and length).. How can I read each line into a Java class into a 2D array with rows and columns?

Example :
import javax.swing.*;
import java.util.ArrayList;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.File;
public class ReadInto2DArrayExample {
    public static void main(String[] args) {
        ArrayList array = new ArrayList();
        char [][] twoDimesionArray = null;
        try
            JFileChooser fileChooser = new JFileChooser();
            if (fileChooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION)
                File file = fileChooser.getSelectedFile();
                BufferedReader reader = new BufferedReader(new FileReader(file));
                String data;
                //Read from file
                while ((data = reader.readLine()) != null)
                    //Convert data to char array and add into array
                    array.add(data.toCharArray());
                reader.close();
                //Creating a 2D char array base on the array size
                twoDimesionArray = new char [array.size()][];
                //Convert array from ArrayList to 2D array
                for (int i = 0; i < array.size(); i++)
                    twoDimesionArray[i] = (char [])array.get(i);
                //Test the 2D Array
                for (int y = 0; y < twoDimesionArray.length; y++)
                    char [] temp = twoDimesionArray[y];
                    for (int x = 0; x < temp.length; x ++ )
                        System.out.print(temp[x]);

How can i have a refrence of a java class object instance in my c++ project

Hi!
How can i have a refrence of a java class object instance in my c++ project. Is there a way?

The second question is the big one. The first question is half of the problem of "c++ to java" invocation and access. But the other half which is "java to c++ " invocation and access is still not solved. jni only provide the "java to c++ " DLL invocation Wrong,
Using JNI your java classes can have methods implemented in C/C++.
Using JNI you can call java classes.
There is no other possible interaction between C++ and java, so it does it all.

How to execute a jsp instruction from a java class?

How to execute a jsp instruction from a java class?
Any help please.
Thank's

I'll detail my problem:
Supposing that I have a jsp file called: start.jsp
In the start.jsp I instanciated an object called global from the class Global ( for example ).
Then, I called a custom taglib:
<ix:mytag/>
In the suitable tld file: the mytag is defined:
<tag>
<tag class>Tag1<.....
The java file Tag1 has method:
doStartTag(){
// here is the problem
global.doSomeFunctions();
Okay, the problem is that the object gobal is not defined in the class Tag1. what to do?
I think that I have to pass the object global as a parameter to the class Tag1. How to do that?
Actually, the problem was to insert the follwoing in the doStartTag method:
doStartTag(){
pageContext.getOut().print("<%= hello world %>");
The output is <%= hello world %> not hello world.
Okay, the new problem is how to pass an object as a parameter to a class called from a tld file.
Any help please.
Thank's too much

How to pass an argument to a standalone java class in JDeveloper

To the experienced:
In JDeveloper when you write a java class with a main() method that takes no argument, you just right click the java file and select Run to run the program. But suppose the main() method takes arguments, how do you pass your arguments to the program? This is especially a problem as I use the studio version of JDeveloper (Versions 10.1.3.4 and 11.1.1.3) that each uses the version of JDK bundled with it, rather than the JDK (which is yet another different version) installed at the OS level of the PC.
Many thanks for your help!
Newman

Hi, Puthanampatti,
Suppose a java class has a main() method:
<pre>
public class FormatTerm {
public static void main(String[] args) {
String year = args[0];
String semester = args[1];
</pre>
What I want to know is how to pass the arguments when invoking FormatTerm within JDeveloper (i.e., without going out of JDeveloper to invoke FormatTerm on a command line in DOS). I would appreciate it very much if you know how to do that in JDeveloper 11g (I use Version 11.1.1.3) and could help me out.
Thank you very much for your help!
