Need Help with Java error code:
I just installed an update suggested by my computer :( and now when I try to access different areas of sites I visit I get the following error:
"several java virtual machine running in the same process caused an error"
Can someone please help me undo this...I am very frustrated!
Thanks,
LorriYour problem may be:
The Microsoft Java JVM that comes with some versions of the OS is earlier on the PATH (Look inside the WINDOWS directory)
You may have several other JVMs on your PATH due to various server installations.... Oracle has one! Sybase has one, so do many other such RDBMSs.
Your "Browser Plugin" may install one.
You may have installed a couple.
You may not have JAVA_HOME set so its checking the PATH
I know what you may be thinking now... how in the world do I find them all?
Examine the output of the commandline call:
dir \java.exe -s -

PI File adapter has a processing option u2018Empty-Message Handlingu2019 to ignore or Write Empty Files. In case there is no data created after mapping on target side then this option determines whether to write an empty file or not. But there is a catch to this option when it comes to using it with File Content Conversion which is described in SAP Note u2018821267u2019. It states following:
I configure the receiver channel with File content conversion mode and I set the 'Empty Message Handling' option to ignore. Input payload to the receiver channel is generated out of mapping and it does not have any record sets. However, this payload has a root element. Why does file receiver create empty output file with zero byte size in the target directory? Example of such a payload generated from mapping is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:test xmlns:ns1="http://abcd.com/ab"></ns1:test>
solution :
If the message payload is empty (i.e., zero bytes in size), then File adapter's empty message handling feature does NOT write files into the target directory. On the other hand, if the payload is a valid XML document (as shown in example) that is generated from mapping with just a root element in it, the File Adapter does not treat it as an empty message and accordingly it writes to the target directory. To achieve your objective of not writing files (that have just a single root element) into the target directory, following could be done:
Using a Java or ABAP Mapping in order to restrict the creation of node itself during mapping. (This cannot be achieved via Message Mapping)
Using standard adapter modules to do content conversion first and then write file.
can someone help with java mapping that can be used in this case?Hi,
You have not mentioned the version of PI you are working in. In case you are working with PI 7.1 or above then here is the java mapping code you need to add after message mapping in the same interface mapping

FileInputStream in=new FileInputStream("C:\\apps\\sdn\\rootNode.xml");
FileOutputStream out=new FileOutputStream("C:\\apps\\sdn\\rootNode1.xml");
genFormat.execute(in,out);
catch(Exception e)
e.printStackTrace();
The code for PI 7.0 should also work for PI 7.1 provided you use the right jar files for compilation, but vice-versa is not true.
Could you please let us know if this code was useful to you or not?

Installing Elements 11 on Mac. Need help with install error "Setup wants to make changes."
Installing Elements 11 on Mac 10.8.2. Need help with install error: Setup wants to make changes. Type your password to allow this." After entering Adobe password, nothing happens. Locked from further installation. Any ideas? Adobe phone support could not help.
Just before letting changes (installation in this case) be made on the system, Mac OS prompts for password & this has to be the Mac system password. This password prompt is the system's own native prompt & would accept the system password only. Please make sure it is the right system password (all/admin rights) and the installaion should run.

If Dreamweaver shows a message saying "the following JavaScript error(s) occurred", it's usually a sign of a corrupt cache file. The first thing you should always be to delete the file cache. If that doesn't work, delete your personal Configuration folder. Please go through the steps mentioned in thread Deleting a corrupted cache file.

Help with the error message that ADE is not allowed to copy a book onto my Nook. I have tried authorizing and unauthorizing many times--at wits end with this issue.
I too am having the same problem. I have a new hard drive that was imaged from the old one and I'm trying to side load a book to my Nook Simple Touch.. I first installed ADE 4 then borrowed and downloaded a book from Overdrive. I tried a few times to delete and reauthorize both the computer and the Nook and each time I get an authorization error when I try to side load the book. I then found on the Nook forum that the Simple Touch and ADE 4 don't get along. So I uninstalled ADE 4 and installed ADE 3.
I then followed this recommended procedure found on the forum: I deleted the Digital Editions folder from my Nook, launched ADE 3 and authorized the computer, then connected the Nook. For a few seconds, hovering the mouse over the setting icon for the Nook displayed everything on the context menu grayed out. But then it showed the context menu and I was able to display the Nook's authorization, which was the same as the computer's. Still get the same error side loading the book. Deleting and reauthorizing doesn't help. And the Digital Editions folder is still missing from the Nook. -
New @ RMI need help with java.rmi.UnmarshalException: error unmarshalling
Hi @ all out there,
I'm new with Java RMI and have to write a EventSystem for an college project where clients can subscribe to a topic and get notified when someone publishes a message to the subscribed topic.
At server-side I have a class called EventSystem that provides methods for subscribing and unsubscribing from topics, and also for posting messages (for publishers).
To subscribe i thought that the client must specify the topic and also itself ( means that a client calls in this way: obj.subscribe("mytopic", this).
The EventSystem handles a list of all clients, and whenever a new message is posted it goes trough all clients and invokes the handleMessage(String msg) method that all Clients have to provide.
On my local machine without RMi this concept works just great.
I now tried to get it working using RMI , but I get the following Exception when starting the client (the server starts fine) :

Need Help With Java Query String
I'm new to Java and I'm passing data via a URL to another page(I'm not using a form). I have been succesfull in decoding the string to return the name value below:
<SCRIPT LANGUAGE="JavaScript">
function decodeSearchString() {
var nameValue = new Array();
var searchStr = unescape(location.search.substring(1));
if (searchStr) {
var formElement = searchStr.split("&");
var tmpArray = new Array();
for (k = 0; k < formElement.length; k++) {
tmpArray = formElement[k].split("=");
nameValue[tmpArray[0]] = tmpArray[1];
return nameValue
var srchData = decodeSearchString();
</SCRIPT>
However, now I need to add the value returned from the above srcipt to the Java script listed below:
<SCRIPT Language="Javascript" SRC="#srchData.link#?open&pID=PAR"> </SCRIPT>
This above script if working will add the HTML from the URL query to the page, but I keep getting a Java Error with this script. Please Help !I assume you are using a JSP page and not just solely doing Javascript. IF you are using JSP, then read on. Otherwise, I can revisit your script.
To obtain the value of the query string, you would use a method call such as:
String strQuery = request.getQueryString()
Or, to get a single parameter off the query string, you can call:
String strSearchData = request.getParameter("paramname");
Or, if you want all the parameters and values instead of just one long string you can call:
Enumeration enumParamNames = request.getParameterNames();
You can use the above enumeration in combination with getParameter() to get the values.
In order to build your script line and add the query string, you would then do something like this:

Need help with Java applet, might need NetBeans URL
I posted the below question. It was never answered, only I was told to post to the NetBeans help forum. Yet I don't see any such forum on this site. Can someone tell me where the NetBeans help forum is located (URL).
Here is my original question:
I have some Java source code from a book that I want to compile. The name of the file is HashTest.java. In order to compile and run this Java program I created a project in the NetBeans IDE named javaapplication16, and I created a class named HashTest. Once the project was created, I cut and pasted the below source code into my java file that was default created for HashTest.java.
Now I can compile and build the project with no errors, but when I try and run it, I get a dialog box that says the following below (Ignore the [...])
[..................Dialog Box......................................]
Hash Test class wasn't found in JavaApplication16 project
Select the main class:
<No main classes found>
[..................Dialog Box......................................]
Does anyone know what the problem is here? Why won't the project run?

That wasn't attention-grabbing enough apparantly. Let's try it again.

Hi everybody,
I have a simple Java application that has a JFrame containing a TextField displaying some text inside it. I am using the NetBeans IDE. I am trying to Enable Java Web start for this application. The steps I have taken upto now are:
1. Right click on Project, Java Web Start -> Enable Java Web Start. This created the jnlp file.
2. In the Resources section, I added the jar file for swing. ( I am not sure if I have to add the path for jnlp.jar etc, or are these found automatically?)
3. Right click on Project, Java Web Start -> Deploy with Java Web Start. This launches the browser with the Click me link, but on clicking this link, I get the following error.
description The server encountered an internal error () that prevented it from fulfilling this request.

Thanks
GeorgeI am not sure what it has to do with servlets, I just followed a tutorial on using Netbeans with Java Web Start, and did only the steps as mentioned in my first post. And ended up with the error.
Anyways, I added the jnlp jar files(jnlp.jar, jnlp-servlet.jar, jardiff.jar) in the WEB-INF/lib directory. And it seems to deploying it now. I can get my application to load on clicking on the "Click me" link. But the controls on my application don't seem to be working.
Also, when I try to Right click on my project -> Java Web Start -> Run with Java Web Start, I get the following error message,
javaws-run: C:\Documents and Settings\Lux\Visualization\nbproject\build-jaws-impl.xml:36: Execute failed: java.io.IOException: CreateProcess: C:\j2sdk1.4.2_13\bin\javaws "file:///C:/Documents and Settings/Lux/Visualization/Visualization.jnlp" error=2
BUILD FAILED (total time: 0 seconds)
Any help appreciated.
Thanks.
George
