Call Java function from multithreaded VC++ application
Friends, I want to call Java function from two threads of a single VC++ application. I can call it from single thread but when I call it from another thread also, JNI_CreateJavaVM() replies with an error.
Please......help meYour posting is ambiguous. My impression is that you have two threads, both trying to create a java VM?

Problem while calling java function from html
when i tried to call a java function from html i'm getting an error
object don't support this property.
what could be the reason.
This is my html.
I got this from this forum only.
My applet is accessing the system property "user.home".
I ran it in IE
<DIV id="dvObjectHolder">Applet comes here</DIV>
<br><br>
<script>
if(window.navigator.appName.toLowerCase().indexOf("netscape")!=-1){ // set object for Netscape:
document.getElementById('dvObjectHolder').innerHTML = " <object ID='appletTest1' classid=\"java:test.class\"" +
"height=\"0\" width=\"0\" onError=\"changeObject();\"" +
">" +
"<param name=\"mayscript\" value=\"Y\">" +
"<param name=\"archive\" value=\"sTest.jar\">" +
"</object>";
}else if(window.navigator.appName.toLowerCase().indexOf('internet explorer')!=-1){ //set object for IE
document.getElementById('dvObjectHolder').innerHTML = "<object ID='appletTest1' classid=\"clsid:8AD9C840-044E-11D1-B3E9-00805F499D93\"" +

<input value="Javascript to java" type=button onClick="document.appletTest1.fromJavaScript()">I tried this example using the repy given to an earlier post.
But its not working with me.
What i did in addition was adding plugin.jar to classpath to import netscape.javascript.*;
Let me add some more details
1) I'll add the stack trace
2) my java progrma
3) batch file to sign the applet.
1) This is the stack trace i don't know whether u will undertand this

Newbie Help: Calling Java function from XSLT
Hi everyone!
I am trying to call a java function from my XSL file. like...
<xsl:stylesheet version="1.0"
xmlns:java="http://xml.apache.org/xslt/java"
xmlns:fn="http://www.my.com/xslt"
exclude-result-prefixes="java fn">
<xsl:variable name="embeddedpic"
select="formData/instance/EmployeePicture" />
<xsl:variable name="pic" select="fn:com.my.utils.ConversionUtils.base64DecodeString($embeddedpic)"/>I am getting this exception in calling the above java function from my XSLT (XalanXPathException: The function number 'http://xml.apache.org/xslt/java:com.my.utils.ConversionUtils.base64DecodeString' is not available.)I have the function lib file in my classpath but still i am getting this error. Any info is highly appreciated.
ThanksTry this.
<?xml version="1.0" ?>
<xsl:transform version="1.0" xmlns:fn="com.my.utils" >
<xsl:variable name="pic" select="fn:ConversionUtils.base64DecodeString($embeddedpic)"/>
etc.
as long as your code is in the classpath it should find it.

JCo Outbound( calling Java Function from ABAP )
HI,
I want to call a JAVA function from ABAP.I have installed the JCo toolkit and included the sapjco.jar file in the classpath of my system.
When i execute the program(Example5.java,provided with sapjco.zip) from the command prompt,it is working fine,the server listens to the calls made from ABAP via RFC destination.
But if i copy the same program in NWDS in a JAVA project,to run it from there as JAVA application,after including the sapjco.jar file in the project JAVA build path,i get the following error,marked by a red cross ,at the head of the program,even before i run it.
<b>This compilation unit indirectly references the missing type com.sap.jdsr.writer.DsrIPassport (typically some required class file is referencing a type outside the classpath)</b>
What changes do i need to make,to run it from NWDS?
I tried to include the sapjcorfc.dll file along with the sapjco.jar in the java build path,but it doesn't help.
Please tell how to solve this issue?
Regards,
Siddharthahello sid,
which jco version are you using?
are you using the same jco lib when running in command
line and in nwds?
if you are, try checking the order of the your classpath.
your jco lib (which you are using in command line) should
come first in order prior to the default libraries in your project.
regards

Calling Java Function from XSL
I'm trying something I think is fairly simple and keep getting errors during the process. I'm just trying to parse an XML file and call a java method from a simple java program called HelloWorld using an XSL stylesheet.
I get the following error: Error while parsing XSL file (Extension function namespace should start with 'http://www.oracle.com/XSL/Transform/java/'.). Here is my XSL. I know the oracle namespace is not necessary, it was added due to the error I was receiving:
<?xml version = "1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:oracle="http://www.oracle.com/XSL/Transform/java/"
xmlns:xalan="http://xml.apache.org/xalan"
xmlns:redirect="http://xml.apache.org/xalan/redirect"
xmlns:jfctn="com.raytheon.iis.temp.HelloWorld" exclude-result-prefixes="jfctn"
exclude-element-prefixes="oracle redirect"
version='1.0'>
<xsl:template match="/">
<xsl:value-of select="//title"/>
<xsl:value-of select="//author"/>
<xsl:value-of select = "jfctn:hello()"/>
</xsl:template>
</xsl:stylesheet>
Here is my java file:
public class HelloWorld {
public static String hello() {
return "Hello World";
And here is my simple XML file:
<source>
<title>XSL</title>
<author> John
Smith</author>
</source>
Any advice/ideas would be greatly appreciated. Thanks.
JimmyAfter some trials I've come up with a more specific issue regarding this error. Here is my new code that works on a machine that does not have a file called xmlparserv2.jar (In my stack trace I noticed it referring to the oracle.xml.parser.v2 so I'm assuming this file and path setup that refers to this file is the issue). Unfortunately I have other programs that need this file and setup so I was wondering if anyone knew some alternate setup or workaround to resolve this issue.
The following works fine for me using xalan on a server with the most recent jdk 1.4 setup.
Here is the new XSL code similar to the one listed above. The XML is the same as the previous post.
<?xml version = "1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:value-of select="//title"/>
<xsl:value-of select="//author"/>

Calling JAVA Functions from XSLT
Hi,
I am trying to invoke a Java Extension Function from a XSLT. I added both the class file and the XSLT file to a folder, then zipped the entire folder and uploaded into the Archive for my Interface MApping.
The CLASS gets loaded but the runtime engine gives an error when calling the JAVA Function.
Here is what it says:

Any help or suggestions to solve this problem would be greatly appreciated.

AHi,
Thanks for looking into this.
1. I have verified that the path in the zip file is correct i.e com/sap/test/stringHandler.class
2. test1.xsl is in the root folder i.e No path.
3. I see the Message in the stacktrace saying "Loaded Class com/sap/test/stringHandler.class " but after that I get a runtime MApping Error and it says "CLASS_NOT_FOUND".
Can you please tell me why is this happening?
Thanks

Calling Java function from java script function
Hello,
I have a jsp in which on button click i am calling a java script function. now there is some data that i want to insert in a table on click of the same button. But in order to do that i need to write java code. but if i write java code inside the script function that is called on button click it doesnt work. what i understand is that i need to make a java function inside the jsp & call that from the script function. can someone tell me how to do that ?

Help with calling java functions from javascript
I am using javax.script to interpret javascript from a java applet. it loads the js file into a string, and then does engine.eval(script_string). My question is, how would I make functions in the class file that are available to javascript?
Update: Instead of that, I am loading a js script that will contain all of the usable functions. Here it is:
//core.js for Javasphere 0.31
var pkgs = new JavaImporter(java.lang, java.lang.System, java.awt);
with(pkgs) {
function Abort(msg) {
var graph = new Graphics();
g = graph.getgraphics();
g.drawString(msg, 20, 20);
}When I do engine.eval("Abort(\"something\")"); it throws this error:
javax.script.ScriptException: sun.org.mozilla.javascript.internal.EvaluatorException: error instantiating (0): class java.awt.Graphics is interface or abstract (<Unknown source>#8) in <Unknown source> at line number 8Eggbertx, let's start from scratch if you don't mind. Say you have this Applet
pubic class MyApplet extends Applet
String message;
//CALL THIS METHOD FROM JAVASCRIPT
public void setMessage(String msg)
message = msg;
// this saves you from having
// to call getGraphics() from JavaScript
repaint();
public void paint(Graphics g)
g.drawString(message, 10, 30);
}Then in your HTML file you may have something like this:
<input type="text" id="msg" value=""></input>
<input type="button" value="Set Message" onclick="setAppletMessage()"></input>
<applet id="myApplet" code="MyApplet.class" width="400" height="100"></applet>And in the JavaScript file:function setAppletMessage()
var msg = document.getElementById("msg").value;
document.myApplet.setMessage(msg);
}This is about all you really need to do. See how the Graphics object is no longer in your .js file?
Note: You may run into other difficulties in getting this code to work because of browser, security, or some other pain-in-the-neck issues, but this is the idea.
Eggbertx, I see you added a star to my first post and I think you should take that off because:
1. <tt>Component</tt> is abstract... so you can not call the <tt>new</tt> operator.
2. The call <tt>component.getGraphics()</tt> is not going to work either, because <tt>component</tt> was never created. -
Is it possible to call Java functions from XSLT, using standard Java 6?
I have seen examples, but the examples are always the most simple case, which even I can already get working. The case where no arguments are passed to the java function.
As soon as I try to pass an argument to the java function, i get a stupid unhelpful error message (as always error messages are unhelpful).
Or am I wasting my time using the standard provided java parser, and need to use apache or something?
anyone who can provide me with a couple lines of working code is to me a saint!
At the moment I am using calling a named template, and passing a param into this.
I want to use this param as an argument in the Java function.
Is this possible?
example code:
<xsl:template name="calc-age">
<xsl:param name="dob"/>
<xsl:variable name="sdob" select="java:lang.String.new($dob)"/>
<xsl:value-of select="java:toString($sdob)"/>
</xsl:template>I have fixed it.
I had to call an xslt 1 function 'string' on the variable before passing it into the java function (see below).
<xsl:template name="calc-age">
<xsl:param name="dob"/>
I know that the value of the param is: <xsl:value-of select="$dob"/><br/>
<xsl:variable name="poo" select="$dob"/>
<xsl:variable name="sdob" select="java:lang.String.new(string($poo))"/>
And here again, we try to print a variable<xsl:value-of select="$poo"/> <br/>
And here again, we try to print the result of the java call<xsl:value-of select="java:toString($sdob)"/> <br/>
and here is our variable sdob <xsl:value-of select="$sdob"/>
</xsl:template> Now this is APPARENTLY a xslt-1 function,
but the reference I had been using for this is
http://www.w3schools.com/xpath/xpath_functions.asp it is linked to by a reference that calls these xslt-2 functions.
Maybe they are mixed xslt-1 and xslt-2 functions?
How am I supposed to know?
Where is a good (plain and simple, easy to read) reference for xsl, so i know which functions are which?
Anyone got a good answer to that question? -
Is it possible to call a java function from plsql?
I have a plsql script which loads data in to a table. One of the fields is a notes field. I would like to use advance offerings of java to manipulate the data before inserting. Is there away I can pass the data to a java function and have it return the manipulated data?
Thanks
AaronYou can use java stored procedure to call java function from plsql.
1. Create a java class with a static function(which will be called from plsql).
2. Compile and load the class into database using LOADJAVA command.
3. Create a wrapper stored procedure or function in plsql which calls the above java function.
4. Access this plsql procedure like normal database procedure. This will invoke underlying java function in which you can do all the processing and return result.
Refer this url for help on implementing above steps :

Type Mismatch error while calling a Java Function from Visual Basic 6.0...
Hi,
I'm having a problem in calling the Java Applet's Function from Visual Basic. First, I'm getting the handle of the Java Applet and components of it using "Document.Applets(n)" which is a HTML function. I'm calling this function from Visual Basic. My code is something like this...
' // Web1 is IE Browser in my Form.
Dim Ap,Comp
Dim Bol as Boolean
Bol = true
Ap = Web1.Document.Applets(0).getWindow() ' \\ Gets the Parent Window.
Ap.setTitle("My Java Applet") ' \\ Sets the Title of the window.
msgbox Ap.getVisibility() ' \\ This will return a Java boolean ( true or false )
Ap.setVisibility(Bol) ' \\ Function Syntax is : void setVisibility(boolean b)
Here in my code , i'm able to call any function that which accepts Integer or String but not boolean. So, i m facing problem with Ap.setVisibility() function. It gives me a "Type mismatch error" while executing it. Can you please tell me a way to do this from Visual Basic !
I'm using Visual Basic 6.0, Windows 2000 , J2SDK 1.4.2_05.
Please help me Friends.
Thanks and Regards,
Srinivas Annam.Hi
I am not sure about this solution. try this
Declare a variable as variant and store the boolean value in that variable and then use in ur method.
Post ur reply in this forum.
bye for now

Calling a java function from xquery
Hello,
I'm pretty new to ODSI and xquery, so forgive me if what I'm asking is too trivial, but I need to find a way to call a java function from inside xquery. I know xquery can do this through external functions, but can't find any example on how the query prolog declaration should be, nor how the function should look like. Could someone enlighten me?
Thanks,
Pedro IvoYou can do this 2 ways that I know of (Mike probably has more ideas too)
1. Register an inversion function:
[How to use an inversion function|http://download.oracle.com/docs/cd/E13167_01/aldsp/docs32/dsp32wiki/Using%20Inverse%20Functions%20to%20Improve%20Query%20Performance.html]
2. Create a physical data service based on a java function. I have used this approach for both custom JDBC database operations and straight Java processing, with pretty good results.
Good luck,
Jeff
