"A null value was pasAlright, I'll try to keep it as simple as possible. If that's not going to work out, we can always complicate it later :)
I suppose you had a look at the link and I assume you know about threads.
We can easily fix this issue if you are instantiating, calling and disposing the object within one thread, e.g. you use it only in one method like
public mySwtExecutionMethod(String fileName){
WordSearchReplace replace = new WordSearchReplace();
// do your replacing here
replace.dispose();
// no reference to replace is left so it won't escape this thread
}Now the fix for your class becomes simple. As you remember from the link, you have to call all methods from within the UI thread. We will now create a Display every time upon instantiation of WordSearchReplace, so the current thread becomes the UI thread.
I had a look at the constructor, and the overhead doesn't seem that bad, provided this is not a dedicated search&replace server.
private final Display display;
public WordSearchReplace()
display = new Display(); // create display
this.shell = new Shell(display); // initialize shell with new display so this thread becomes the UI thread
this.frame = new OleFrame(this.shell, SWT.NONE);
this.wordSite = new OleClientSite(this.frame, SWT.NONE, WordSearchReplace.PROG_ID);
this.wordAutomation = new OleAutomation(this.wordSite);
}Since we always create a new Display, we should also dispose it. There is already a dispose() method, so we just have to add to it
display.dispose();That's it!
If you hold on longer to your reference and this isn't working for you, you'd have to do a lot more synchronizing and that the UI thread still exist as long as the reference.

Create a custom dock/application icon for .jar files built in eclipse
I've spent the better part of the afternoon trying to figure out how to apply a custom icon to jar file that I created in eclipse. I am presently using eclipse v3.5 on Mac OS X 10.6.2 and have yet to find a way to change the java coffee cup logo in the document icon for my jar files created in eclipse. Is there some way I can call a specific Apple class in Eclipse to change the dock/application icon of my .jar file?
I found this link that uses a class that seems to be specific to XCode to change the icon of the .jar file.
What I mean by change the icon of the jar file, I mean change the icon used in the dock, and also the icon used when the "command+tab" switcher pops up. Presently, I have the black console icon with the text "exec" in the upperleft.
If anyone has any good links on this topic or even better knows the code I need insert into my program I would be highly greatful.
cheers

RegardsYou can try asking third party API questions here, but you'll likely be waiting a long time. You are better off looking for a forum that is specifically for your third party technology; in this case I would look around on the Eclipse website since its their tech.

hi all,
i had been trying to debug the jsp code in eclipse. which requires the project to identify few class files. i am not able to find the jar file which has the implementation of the below mentioned files. (i am using jboss as application server)
org.apache.taglibs.standard.tag.el.core.SetTag
org.apache.taglibs.standard.tag.el.fmt.BundleTag
the list is long... but all the class files refer to the same package.
your help is much appreciated.
--thanks a lot.hello ritu...
you would require standard-1.1.2.jar .....
try with that....
u can download it from -
http://www.java2s.com/Code/Jar/CatalogJar.htm
classes contained in standard-1.1.2.jar -
org.apache.taglibs.standard.tag.el.core.OutTag.class

Where to download java jar file with org.apache.xml.serialize.OutputFormat?
Dear Friends,
I try one program, it import org.apache.xml.serialize.OutputFormat;
but I cannot fine it after I google a while.
where can I find and download jar file that contain this:
org.apache.xml.serialize.OutputFormat
I use JDK1.6
Thanks
sunnySo, to clear things up, there is no org.apache.xml.serialize.OutputFormat.JAR
OutputFormat is a class.
As I said in my previous post if you go at the xerces project home page (here) you will find a compiled version of xerces [here - direct link -> (fool proof)|http://archive.apache.org/dist/xml/xerces-j/Xerces-J-bin.1.4.4.zip]. If you extract the archive you will find a compiled jar called xerces.jar. Open that one with winrar/winzip or whatever, browse to org\apache\xml\serialize\OutputFormat.class and there you go, you have it, just link this xerces library to your project...
PS. Try searching on Google for "Google tutorial" -
Which jar file has org.w3c.dom ?
Hello,
Can someone tell me please which jar file has this package
org.w3c.dom ? or Where can I find ?
Additionally : Is there a reference where I can easily see ?
It takes time if you have so much Jar files .
Many thanks
CadoIf you are looking for an XML parser try the xerxes.jar that can be found at the Apache Project web site.

Help on jar file for org.apache.xml.serialize.OutputFormat
Hi all, I need help regarding on org.apache.xml.serialize.OutputFormat
and org.apache.xml.serialize.XMLSerializer. May I know which jar files
contain these? ThanksAfter installing jdk 1.5 the problem is now resolved and after prefexing a few of the import statements with com.sun.
There are however some more classes as part of the Xerces 2.7.1 jar file as compared to the JWSDP 1.6 installed and this requires the xercesimpl.jar to be included in the classpath.
Rgds,

Hi!
I'm a java beginner and i have to create an outlook appointment via java. Actual the Outlook-appointment window is to be opened and one could create a new appointment...
To find some helping code in the www is complicated or not feasible. But for all that i've found the following (creates a new outlook contact) and I wonder if i could use fragments of it to solve the task. Or has anyone got another code for the interaction of Java and SWT OLE to create an outlook appointment? :
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.ole.win32.OleAutomation;
import org.eclipse.swt.ole.win32.OleClientSite;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
public class OutlookOLEAutomationThroughSWTExample {
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setText("Outlook Automation");
shell.setLayout(new FillLayout());
OleFrame frm = new OleFrame(shell, SWT.NONE);
OleClientSite site = new OleClientSite(frm, SWT.NONE, "Outlook.Application");
OleAutomation auto = new OleAutomation(site);
int[] CreateItemDispId = auto.getIDsOfNames(new String[] { "CreateItem" });
// Outloook contants you'll find here: http://www.datalife.com/yitz/automat...constants.html
final int OUTLOOK_CONTACT_ITEM = 2;
Variant contactItem = auto.invoke(CreateItemDispId[0], new Variant[] { new Variant(OUTLOOK_CONTACT_ITEM) });
OleAutomation contactItemAutomation = contactItem.getAutomation();
int[] CompanyNamePropertyDispId = contactItemAutomation.getIDsOfNames(new String[] { "CompanyName" });
contactItemAutomation.setProperty(CompanyNamePropertyDispId[0], new Variant("xyz.com"));
int[] Email1AddressPropertyDispId = contactItemAutomation.getIDsOfNames(new String[] { "Email1Address" });
contactItemAutomation.setProperty(Email1AddressPropertyDispId[0], new Variant("[email protected]"));
int[] SaveDispId = contactItemAutomation.getIDsOfNames(new String[] { "Save" });
contactItemAutomation.invoke(SaveDispId[0]);
contactItemAutomation.dispose();
shell.dispose();
auto.dispose();
site.deactivateInPlaceClient();
site.dispose();
frm.dispose();
}.... any help would be appreciated! I become desperate!
Regards,
EnnBeeHi...
I suspect one reason that you havn't had any replies
is because your starting point is not yet clear.
My english is baddish, sorry :(
I want outlook to open the appointment item window if i click on a button in my java application... and i could'nt find any solution! SWT OLE interaction with java could be one way to do so, i'd thought- but i don't know how...
Have you compiled and run the code you have posted?
Sure & it works... but as i said: i don't want to create a new outlook contact but a new outlook appointment!
This is what i've worked out till now, but it leads nowhere:
public OpenOutlook() {
super("New Outlook Appointment", IAction.AS_PUSH_BUTTON);
this.setImageDescriptor(UiPlugin.getImageDescriptor(OUTLOOK_IMG));
this.setToolTipText("Outlook");
public void run() {
try{
Display display = new Display();
Shell shell = new Shell(display);
OleFrame frame = new OleFrame(shell, SWT.NONE);
OleClientSite site = new OleClientSite(frame, SWT.NONE, "Outlook.Application");
site.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
OleAutomation auto = new OleAutomation(site);
int[] dispIDs = auto.getIDsOfNames(new String[] {"NewAppointment"});
auto.invoke(dispIDs[0]); //open inspector for new appointment
auto.dispose();
shell.dispose();
display.dispose();
catch (SWTException e){
e.printStackTrace();
}..unfortunately it causes an "Unhandled event loop exception, Reason: Invalid thread access" if i use it as in the codesnippet above...
Got any ideas?

SWT Libraries in .jar file - UnsatisfiedLinkError
I have a program that runs inside another application like a plug-in. I'm using the org.eclipse.swt toolkit.
The program runs great the first time I run it, but when I try to run it a second time I get:
Caught Exception: java.lang.UnsatisfiedLinkError: no swt-win32-3550 or swt-win32 in swt.library.path, java.library path, or the jar file.The libraries are in my jar file and as I indicated, the program works great the first time it's run.
I cannot control each user's environment so I don't think the CLASSPATH and load() options will work for me. Also, for distribution purposes, I really need to keep all the required libraries in the .jar file.
Could someone explain this to me?
Any suggestions on how to proceed?QuirkyGal wrote:
Well, we have multiple locations with different environments. We have distributed environments and we have standalone installations. And we have business partners with no IT departments and others with small IT departments who are just too busy. And most of the people we work with are on Windows machines, but not all.
Ok, but none of that changes what I said.
Of course I could distribute multiple files. I'd just like to avoid that if possible. And I thought that the big advantage to using swt is that it would use the system libraries (avoiding potential display problems) but I wouldn't have to concern myself with which system the user is on because the toolkit would take care of all that. Is that not how swt is supposed to work?
It doesn't matter who loads the shared library - what I said still applies.
So the OS loads the library? Ok. I thought the JVM loads the library. So is there a way to tell the system to unload it? Or to tell it that it's already loaded?
Unloading requires that you use a class loader and what some call a trick with the garbage collector.
However a library is loaded into the process space (but by the OS) not into the OS space. So restarting the entire process requires reloading it.

I'm just not getting why it works the first time...Couldn't say. I wasn't really commenting about that but rather your other comment.
You might want to specifically define how you get to the "first" and "second" time. -
Exporting JOGL project in Eclipse to an executable jar file
I'm currently using Eclipse on Windows as my IDE and I've gotten [JOGL |https://jogl.dev.java.net/] to work on it, however if I try to export the project (I've just got a simple example that runs perfectly through eclipse) to an jar file (either the JAR or Runnable JAR option) the jar file doesn't do anything. If I go to the command line and type "java -jar <the jar file> -Djava.library.path=<where the library files are>" it gives this error:

Any help would be greatly appreciated with some Duke stars ;-)Ok, sounds like it would work, although I've never done much with loading libraries like you describe, so I could use some extra notes on it.
