Hi All,

I basically have two questions regaring SWT and SWING integration
if I can get the answers for the following that will be great.

1)

I allready have a application(which extends JFrame as follows

public class ExistingAPP extends JFrame implements WindowListener

and then when I try to use the java.awt.Frame xxx=
SWT_AWT.new_Frame(xxxxx);

it gives the following error

Exception in thread "main" java.lang.IllegalArgumentException: adding a
window to a container

The code sample I used is

final Display display = new Display();
final Shell shell = new Shell(display);
shell.setText("SWT Swing Example");
Composite locationComp = new Composite(shell, SWT.EMBEDDED);
final Composite comp = new Composite(shell, SWT.NONE);

Composite tableComp = new Composite(comp, SWT.EMBEDDED);

java.awt.Frame fileTableFrame = SWT_AWT.new_Frame(tableComp);

java.awt.Panel panel = new java.awt.Panel(new java.awt.BorderLayout());

fileTableFrame.add(panel);
LogSvr.logDebug("Going to construct JFram Appliction");
panel.add(new JFrameApplication());

shell.open();
while(!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();

2) The second question is
In a primitive SWT application the above stated JFrameApplication
starts though it gives the above error, but in a wizard based SWT
application it gives the following error and doesnt not start the
application

Unhandled event loop exception
Reason:
com/xxxx/xxxx/......

What is meant by this.

Waiting for a early reply

Thanks,
Peter

Regarding the question 1, I like to have a answer without changing the
existing JFrame application.

thanks

Hi All,

I did further investigation and noticed the following in the .log file.

java.lang.NoClassDefFoundError: com/xxxxx/xx/xx

The Parent Application is a plugin, but the com/xxxxx/xx/xx application is
not a plugin but a different JFrame application.

All the jar files are in the classpath and the application compiles with
no problem, can someone let me know how to handle this.

thanks
Peter

Peter,
for 1) - you can't add frame (JFrame) to frame - it is swing constraint
you can try extract panel from your application and add panel in SWT_AWT
frame
for 2) it depends from 1 probably

I really do not like to change the existing JFrame application. Reason is
it uses lot of properties and features of the JFrame,

Isnt there any other workaround

no, you can open your application in another window only

Not even that,

it gives the following error message in the console

Unhandled event loop exception
Reason:
com/xx/xxxx/xxxxx

Also in the .log file it gives the following error
java.lang.NoClassDefFoundError: com/xx/xxxx/xxxxx

The parent application is a plugin, but the application which gonna popup
is a seperate standolone application.

The compilation and everything is successful

Thanks

Compilation is controlled by the project build path properties. Runtime
is controlled by the manifest (jars have to belong to a plugin). How
have you included your stand alone jars in a plugin, so they can be used
by a plugin?

There are a number of steps for using 3rd party (an external) jars with
plugins ... the easiest is of course creating a New plugin from existin
jar archives. The other steps are available in a couple of other
threads on the news group.

you don't need SWT_AWT for separate window - call your application
with 'new MyApplication()' or similar without SWT_AWT frame
it will open new window
if you have NoClassDEfDoundError add libraries in plugin runtime

Isnt it enough to add the jars as follows in the plugin.xml

<runtime>
<library name="first.jar">
<export name="*"/>
</library>
<library name="second.jar">
<export name="*"/>
</library>
</runtime>

Still it gives the following error

Unhandled event loop exception
Reason:
com/XXXXX/XX/XXXX

What is the physical location that the jar files needs to reside.
Currently I put inside the plugin

eclipse\plugins\com.my.newplugin\

Thanks,
Lalitha

i make separate plugin and lib subdirectory, but it isn't important
you have to add it in runtime and export packages what you want use in
another plugin (i export all ,but it have to export every packages in new
MANIFEST.MF; before it exists *)

you export it on old way (old plugin.xml) and you check is it in runtime tab
is it fine when you use this packages in another plugins (don't add packages
in build path properties - add only dependency for jars plugins - then you
can environment like runtime)
