Running the Swing or AWT code in the UNIX

I have developed the code to modify the XML attribute values using Java. Those attribute values are accepted from the GUI which i have designed using swings as well as AWT.
The code is perfectly working in the DOS/Windows environment. The applet/Display is perfectly popping up and accepting the data and it is making the required changes in the XML and creating the new XML.
But the problem i am facing is,
I compiled the same code in UNIX and then run the code. But it threw the exception as below. Can anyone help me out for this. What i need to do in order to run that code successfully??.
bash-3.00$ java GUIAjay
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:159)
at java.awt.Window.<init>(Window.java:407)
at java.awt.Frame.<init>(Frame.java:402)
at javax.swing.JFrame.<init>(JFrame.java:207)
at GUIAjay.<init>(GUIAjay.java:44)
at GUIAjay.main(GUIAjay.java:39)
I tried to set the X11 window server as:
export DISPLAY=10.5.21.117:0
But yet the User Interface is not popping up in the UNIX??.
May be the problem is because GUI is not supported in UNIX.. So please suggest me on this..

I have to run the code twice

How to set the File Path to run a javascript using Plugin Code?

Hi All,
Im new to Indesign Plugin Development.Can any one help me out with my problem.
What i want to do is to run a javascript using Plugin Code.When i went through this forum i was able to find out that i should use the IscriptRunner Class to automate this.I could also figure out that the Member Function to use is "CanHandleFile" &"RunFile".
The first parameter in CanHandleFile & RunFile Member Function is to specify the path of the JavaScript File i suppose!I could also find out that IDFile has to used to set the file path Information.
But im clueless how to set the Javascript FilePath using IDFile.Can any one help me how to do this?Any Code Snippets Please?
Waiting for reply.
Thanks

Hi, Andreas<br /><br /> Can you explain this in detail? I found it in your post before.<br /><br /> The content of elements are returned through the Characters callback function:<br /><br />From ISaxContentHandler.h:<br /><br />/**<br /> Receives character data<br /><br />The parser will call this method to report each chunk of<br /> character data. SAX parsers may return all contiguous<br /> character data in a single chunk, or they may split it into<br /> several chunks. But all characters in any single<br /> event must come from the same external entity so the<br /> Locator provides useful information.<br /><br />Note some parsers will report whitespace using the<br /> IgnorableWhitespace() method rather than this one (validating<br /> parsers must do so).<br /><br />@param Chars The characters from the XML document.<br /> */<br />virtual void Characters(const PMString& chars) = 0; <br /><br /> What i have done is implement my own SAXContentHandlerServiceBoss, and in my file XXXSAXContentHandler.cpp, I override the fonctions StartElement, EndElement, and Characters() like below: I add the PMString xmlData to collect the file content:<br /><br />class XXXSAXContentHandler : public CSAXContentHandler<br />{<br />void XXXSAXContentHandler::Characters(const WideString& chars)<br />{<br />xmlData.Append(chars);<br />}<br /><br />void XXXSAXContentHandler::StartElement(const WideString& uri, const WideString& localname, const WideString& qname, ISAXAttributes* attrs)<br />{<br />xmlData.Append("<"); xmlData.Append(localname); xmlData.Append(">");<br />}<br />void XXXSAXContentHandler::EndElement(const WideString& uri, const WideString& localname, const WideString& qname)<br />{<br />xmlData.Append("</"); xmlData.Append(localname); xmlData.Append(">");<br />}<br /><br />}<br /><br />and in my program, I use the code below to call the fonction I overrided, but I dont know how I can get the String xmlData I defined in the XXXSAXContentHandler.cpp<br /><br />InterfacePtr<IK2ServiceRegistry> serviceRegistry(gSession, UseDefaultIID());<br /><br />InterfacePtr<IK2ServiceProvider> xmlProvider(serviceRegistry->QueryServiceProviderByClassID(kXMLParserService, kXMLParserServiceBoss));<br /><br />InterfacePtr<ISAXServices> saxServices(xmlProvider, UseDefaultIID());<br />InterfacePtr<ISAXContentHandler> saxHandler(::CreateObject2<ISAXContentHandler>(kXXXSAXContentHandlerServiceBoss));<br />saxHandler->Register(saxServices);<br />bool16 parseFailed = saxServices->ParseStream(readStream, saxHandler);<br /><br />Can you give me any help?<br /><br />Thanks and regards!

Stream-in images from client to server,without running the transmit code

Hello all,
Im using JMF for my current project.Right now,I am trying to only recieve images from the client without the client transmitting it.That is I dont want the transmit code to run on the client.
I should just be able to stream in the images from client to server, without running the transmit code on client.
Can this be done?
Thanks in advance

Can I know more about this?Sure.
<Side A>
You'd just need to write an application that doesn't have a GUI (so, a console-based application) that listens on some pre-determined port for a message to start broadcasting. Maybe you'd send it the IP/PORT number to start broadcasting on. Once it receives that message, it'd start broadcasting the web cam to the IP/PORT number until it received a message to stop. Once it stops, it'll just go back to waiting for the next "start" signal.
<Side B>
On the other side, you'd write an application that sends the start messages, receives/displays the videos, and then sends the stop signal. This will have a GUI, and be your "control program" so to speak.
Then, once of have both of those programs working...if you're using Linux, you're done. If you're using Windows, you'd need to modify the <Side A> program so that it can run as a Windows service.
There are a lot of ways to do this, you can google it or look at the following link:

Running the same code multiple times with different paramters automatically

Hi guys,
I want to run the same code multiple times with different paramters automatically. Actually, I am doing some sample scans which takes around 2 hours n then I have to be there to change the paramters and run it again. Mostly I do use folowing paramters only
X_Intial, X_Final, X-StepSize
Y_Intial, Y_Final, Y-StepSize
Thanks,
Dushyant

All you have to di is put all of the parameters for each run into a cluster array. Surround your main program with a for loop and wire the cluster array through the for loop. A for loop will autoindex an input array so inside the for loop you just have to unbundle the cluster to get the parameters for each run.

Thus, what the correct command i need to run the my code?Then your classpath would be .;mysql.jar (or whatever the heck the name of the connector was).

Show-stopping error when I try to load/run the muse code with JQuery version 1.9.1.

Version 1.9.1, and the muse code uses 1.8.3. As you can see HERE,http://jquery.com/download/ version 1.9.0 was a major milestone release for JQuery that eliminated much of the (deprecated) functionality of earlier versions. Unfortunately, the muse html uses some of that deprecated functionality (specifically, the "browser( )" function HERE)http://jquery.com/upgrade-guide/1.9/#jquery-browser-removed. Thus I am getting a show-stopping error when I try to load/run the muse code with version 1.9.1. Other people have had this same problem (see THIS)http://bugs.jquery.com/ticket/13214.

How to run the sample code using the sdk?

Hi,
I want to run the jsp code from the enterprize sdk available in the sdn community. Can any one tell me how to execute these jsp sample codes and what is the pre-requisite regarding the set up.
I already have the deployment ready.
thanks
AMar

Hi Amar,
To execute samples code, it is same what is required for normal J2EE application.
Make sure add all the jars to your web application.
These jars can be found on your BO server installation if windows.
For BOE XI 3.x
C:\Program Files\Business Objects\common\4.0\java\lib
