Invoke Java 3d from a JSP?

Hi,
I have a sample java code that invokes a Canvas3d and then invokes a 3D object.
Our project goal is to create an online application-- A JSP page which will invoke the java 3d object.
I am working on Oracle JDeveloper and OC4J server.
Currently , the application runs thru a .java file.
I want to know if it is technically possible to create a jsp page and transfer the 3d object generated by this java file onto the JSP?
I tried renaming the main method of the java file to say testMain (made it static method).
Then thru the JSP , i tried to call this testMain method.
It doesnt work.
thanks

HI
I was able to add a canvas3D to a webbrowser via an applet. I suppose you can always invoke an applet from a JSP.

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);

Invoke Java Library from Flex

I have Flex running on Tomcat with LCDS. On tomcat there is a JAR that has classes I'd like to use/interact with from Flex. In the simple LCDS examples they demonstrate having a Product.java class and a matching Product.as class, but the java library I am trying to use has many more classes and would take a long time to copy into Actionscript.
What is the best way to interact with the Java classes (I don't have a web service to use like in the LCDS example).

I only know we can use JNI to invoke native libraries
from Java and I have never used JNI to invoke Java
libraries from native applications (C/C++ programs).
I am going to look through the tutorial you
recommended.The last tutorial. I've only fiddled with it, as it was a bitch. If you don't need to use Suns JVM, I recomend using CNI & GCJ [ http://gcc.gnu.org/java/ ], as it is much neater.
Do you mean JNI is internally implemented by C++s
Runtime.exec method?Write a small Java application which invokes the lib you want, i.e. say you want to use Strings replaceAll method (simple example I know)
class Test {
pubilc static void main( String args[] ) {
System.out.println( args[0].replaceAll( args[1], args[2] ) ) ;
}Then use c++ program to run "/path/to/java Test tast a e" .

How to invoke Java class from post.POST.jsp

Hi All,
I am trying to invoke a simple java method from post.POST.jsp
I am getting below exception while doing it.
org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 32 in the jsp file: /apps/mywebsite/components/customFormAction/post.POST.jsp
The method test() is undefined for the type DatasourceUtil
29:
30:           ///
31:          com.day.test.datasource.DatasourceUtil dsUtil = new com.day.test.datasource.DatasourceUtilImpl();
32:          dsUtil.test();
33:           //dsUtil.validateLogin(request.getParameter("username"), request.getParameter("password"));
34:
35:           ////
It appears to resolve the class correctly. I could run the code, if I only comment dsUtil.test();. As soon as I uncomment, it gives above error.
In the Utill I have a simple void method which will print a simple text. My package structure is as follows.
any help will be great
Tx

1. In the interface [1] not the implementation[2] have u defined the method test?
2. If it is implemented, Change the bundle version in bnd file and make a new build. Then from felix console verify the latest version reflected in the bundles.
If 2 works & you are going to make lot of frequent changes then give the version as snapshot till it get stable.
[1] com.day.test.datasource.DatasourceUtil
[2]   com.day.test.datasource.DatasourceUtilImpl

Invoking BPEL Process from a JSP Page 500 Internal Server Error

Here is the solution:
Properties props = new Properties();
props.setProperty("orabpel.platform", "oc4j_10g");
props.setProperty("java.naming.factory.initial",
"com.evermind.server.rmi.RMIInitialContextFactory");
props.setProperty("java.naming.provider.url", "ormi://localhost/orabpel");
props.setProperty("java.naming.security.principal", "oc4jadmin");
props.setProperty("java.naming.security.credentials", "welcome1");
and several jars have to be added to the project:
Orabpel.jar , Orabpel-common.jar, oc4j*.jar,
%ANT_HOME%\lib\ant.jar;
%ANT_HOME%\lib\xercesImpl.jar;
%ANT_HOME%\lib\xml-apis.jar;

Error Invoking Java class from Stored proc

We are getting this error while calling a stored procedure that invokes a
static function of a java class from inside Oracle 8.1.7.
ORA-29516: Aurora assertion failure: Java thread deadlock detected
ORA-06512: at "APPS.SERVICECONSUMERINVOKE", line 0
ORA-06512: at line 40
In a Toad SQL Window, when I execute the stored procedure that invokes the
java function, it executes successfully on the first attempt. When I try to
execute it again on the same SQL Window, it gives the above error. The java
class is part of a package and indirectly makes a JMS request-reply call
via other helper classes.
The same package works fine from other web containers and
unlike the Oracle JVM Aurora, the JVMs don't detect a deadlock.
Why does the Aurora throw an error?

Did you try issusing a commit and then trying again in Toad SQL Window?
The advice is to contact support:
ORA-29516: Aurora assertion failure: string
Cause: An internal error occurred in the Aurora module.
Action: Contact Oracle Worldwide Support.

Tomcat 6 Calling a Java Servlet from a JSP Page

HelloWorld.java can be compiled by using javac.
Once compiled, HelloWorld.class would be moved to the jservlets folder.
FYI, coding the above url-pattern results in:
HTTP Status 404
The requested resource (/HelloWorldExample/servlet/jservlets.HelloWorld) is not available
The following url-pattern in the web.xml file permits the servlet to be executed but results in a null pointer exception:
<servlet-mapping>
        <servlet-name>HelloWorld</servlet-name>
        <url-pattern>/ </url-pattern>

This problem was resolved.
In hello.jsp
ACTION="servlet/jservlets.HelloWorld">
was replaced with
ACTION="servlet/HelloWorld">

Start java app from a jsp or a servlet?

HI ,
I want to know if it possible to start a java application using Runtime and exec(command).
I mean launch abc.java from abcservlet or from abclaunch.jsp (with a button click) any exmaples ?
thanks,
-G.

I want to know if it possible to start a java
a application using Runtime and exec(command).
I mean launch abc.java from abcservlet or from
m abclaunch.jsp (with a button click) any exmaples ?If a servlet class calls runtime.exec, it'll run a program on the server.
Use webstart or an applet if you want some action to happen at the clients side. Servlets only hand HTML to the client, no Java context.

Invoking java exe from C++ code

Most of my applications are in c++, i have one application in java.
How can I invoke the java application(jar) from c++ code?

Hi We can do this by using EXTERN C functionality provided by c++ ,
by using this we can call the Java functions from Java .class file.
or .jar file.
(for java developers ......its similer to JNI)
if you want more details aboth such code just search it on web , you will get number of programs here.
Thanks,

Invoking Java Applet from SAP Netweaver Eportal using java webdynpro

Hi ,
We are using SAP Netweaver portal version 7.0.WE want to invoke java applet into webdynpro java application on button click.
The Applet should open in a new window when the particular parameter is selected and the button is clicked
The code is given below:
String html = "<HTML> <HEAD></HEAD> <BODY><APPLET code=\"org.faceless.pdf2.viewer2.PDFViewerApplet\" type=\"application/x-java-applet;version=1.4.2_05\" archive=\"bfopdf.jar\" width=800 height=600></APPLET></BODY></HTML>";
IWDCachedWebResource resource = WDWebResource.getWebResource(html.getBytes("UTF-8"), WDWebResourceType.HTML);
resource.setResourceName("HTML_inline.html");
IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(resource.getAbsoluteURL(),"Image");
window.removeWindowFeature(WDWindowFeature.TOOL_BAR);
window.removeWindowFeature(WDWindowFeature.ADDRESS_BAR);
window.removeWindowFeature(WDWindowFeature.STATUS_BAR);
window.open();
But after clicking on button new html window is opening and the applet is not showing properly. The java console showing the error:
java.lang.ClassFormatError: Truncated class file
     at java.lang.ClassLoader.defineClass1(Native Method)

Please suggest how to solve this error.

Hi,
I'm not sure, but I believe the 'code' argument should end with '.class'. However, your implementation of displaying a Java applet seems ok, the error is within the applet's Jar file
Anyway, have a look at http://download.oracle.com/javase/1,5.0/docs/guide/plugin/developer_guide/using_tags.html#applet and http://www.w3.org/TR/html401/struct/objects.html#h-13.4 on how to use the <applet> tag
As a test, you could try and create a local HTML document on your local desktop, including the applet. I would suspect you will receive the same error in your Java console
I believe the only option is to recompile your Java applet (if possible at all) against a newer JDK (1.4 and up)

Running Java applications from within JSP

Hi Folks,
First of all, apologies if this post is either 1) in the wrong forum or 2) a horrendous mis-application of java/JSP :D
I have a java test harness application that I have created, it runs from the command line, taking two arguments (the name of the app you want to test and the location of the properties file) and it then looks up the app in the properties file and tests the application - writing results to html reports and errors to logs... all pretty standard so far.
The apps i normally test are usually on an app server (normally IBMs WAS), so I thought, why dont I create a Web Application with a nice JSP page listing all the applications that can be tested(extracted from the properties file) and allow the user to go to the jsp and just click the "test this service" button or "view results" button for any service - just to make it more manageable.
So I have created the JSP page with the list of applications, and the links to all the result.html files - so now I just need to implement the functionality to be able to hit the link "Test now" and the test harness runs in the background.
Does anyone please have any ideas?
The best i came up with was creating a link to a new jsp page that had the code on it to create the main Test Harness object and then calling the execute() method - however, when i press the link i get taken to the page but my tests arent run? (this test was run on Tomcat if that makes any difference)
Any ideas? of any better ways to approach the task?
Thanks in advance guys!!

Start with Java EE tutorial part II: [http://java.sun.com/javaee/5/docs/tutorial/doc/bnadp.html].
To create a Servlet you basically just extend HttpServlet and implement the appropriate methods, such as doGet() for GET requests and doPost() for POST requests. To run it, you need to define it in the web.xml and map it on an appropriate url-pattern with which you want to invoke the servlet by URL.
To fullfill your requirement, I think implementing doGet() ought to be sufficient. E.g.
yourpackage.YourServlet.javaprotected void doGet(HttpServletRequest request, HttpServletResponse response) {
    YourJavaClass yourJavaClass = new YourJavaClass();
    Object someResult = yourJavaClass.doSomething();
    request.setAttribute("someResult", someResult);
    request.getRequestDispatcher("yourPage.jsp").forward(request, response);
}yourPage.jsp<p>Result: ${someResult}</p>web.xml<servlet>
    <servlet-name>yourServlet</servlet-name>
    <servlet-class>yourpackage.YourServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>yourServlet</servlet-name>
    <url-pattern>/yourServlet</url-pattern>
</servlet-mapping>Invoke it by [http://localhost:8080/yourContext/yourServlet].
