Problem with PJC (Print Dialog) - Forms 10g

Question

I have a problem with my PJC for Forms 10g r2. When I try to connect and run my PJC (raise Print dialog and put printer name in some text item) I get following message:
oracle.forms.net.ConnectionException: Forms session <2> aborted: unable to communicate with runtime process.
     at oracle.forms.net.ConnectionException.createConnectionException(Unknown Source)
     at oracle.forms.net.HTTPNStream.getResponse(Unknown Source)
     at oracle.forms.net.HTTPNStream.doFlush(Unknown Source)
     at oracle.forms.net.HTTPNStream.flush(Unknown Source)
     at java.io.DataOutputStream.flush(Unknown Source)
     at oracle.forms.net.StreamMessageWriter.run(Unknown Source)
When I started application, on Java console I saw this message, so I think the server configuration is fine (I change everything I need in Default.env and FormsWeb.cfg files):
Loading http://devsrv/forms/java/jESPrintDialog.jar from JAR cache
What can I change with server configuration or deploying my project to this PJC can work normaly?
Thanks....

Hi and thanks!
I resolve one part of my problem. Tt was about diferent compiler (in JDeveloper 10.1.3 compiler is 1.5 and in my oc4j server JRE is earlier version, so it can`t work normaly).
I comiled PJC in 1.4 version of compiler and now I can start and run my PJC.
But, there is another problem:
this is my part of java code (note: everything work fine except one line when I want to get printer name from select printer dialog):
try {
boolean b;
PrinterJob job = PrinterJob.getPrinterJob();
b = job.printDialog();
try {
return job.getPrintService().getName();
catch (Exception e) {
System.out.println("Error: "+e.getMessage());
return "My error:";
} catch (Exception e) {
System.out.println("ERROR: " + e.getMessage());
return "Problem with PJC [esoft]";
So, when pjc want to get back printer name
return job.getPrintService().getName();
i get following error (on Java console):
java.lang.NoSuchMethodError

Can you give me some hint about it. Everything is OK now, except this (very important) peace of code!
best regards
