Dear Jason

I am having an issue with the Php Java Bridge..
I have gone live and when the users are using the bridge intensively, with export to pdf everything, after some hours they get the following error message:

Fatal error: protocol error: ,Invalid document end at col 124. Check the back end log for OutOfMemoryErrors. in C:\wamp\www\Medisave\BIRT\JavaBridge3\java\Java.inc on line 869Call Stack#TimeMemoryFunctionLocation10.0015417544{main}( )..\visitBill.php:021.76532705880java_InternalJava->run( )..\visitBill.php:8331.76532706080Java->__call( )..\Java.inc:041.76532706680java_AbstractJava->__call( )..\Java.inc:199951.76532706680java_JavaProxy->__call( )..\Java.inc:185161.76532706680java_Client->invokeMethod( )..\Java.inc:175271.76542706896java_Protocol->invokeEnd( )..\Java.inc:55981.76542706952java_Protocol->finish( )..\Java.inc:133891.76542706200java_Protocol->handle( )..\Java.inc:1286101.76542706200java_Client->handleRequests( )..\Java.inc:1279111.76552706368java_Parser->parse( )..\Java.inc:347121.76552706368java_NativeParser->parse( )..\Java.inc:722133.51432706680java_SocketHandler->shutdownBrokenConnection( )..\Java.inc:701143.51442706608java_SocketHandler->dieWithBrokenConnection( )..\Java.inc:873153.51442706816trigger_error ( )..\Java.inc:869

Restarting Tomcat server resets everything to normal..

I made sure that i had the parameter -XX:MaxPermSize=256M
on the tomcat server

Could you please hint me here? I need to get it solved pretty soon.. I am still doing some research about it on my part..

Thanks in advance..

Dear Jason

I noticed that the export to HTML works fine for around 100 reports..
Its when i call the export to pdf intensively that the out of memory error seems to occur...

Karvesh,

Can you post the code (php) that you are using to export to pdf?

Dear Jason

I noted that this could happen also in the HTML render file..

Please find the html and pdf render files enclosed

clientReceipt.php for the html rendering
clientReceiptPDF.php for the pdf rendering

I was wondering if i increased the -XX:MaxPermSize=256M to -XX:MaxPermSize=512M..
It may buy me some time...

Thanks a lot Smile

Karvesh,

I did no see anything wrong with the code. If you change the pdf php to
first do a run task and then a render task do you get the error?

Dear Jason,

you mean i add the red code within the pdf export one:

$report = $birtReportEngine->openReportDesign("${here}/ReportDesigns/GRN.rptdesign");

$task = $birtReportEngine->createRunTask($report);
$task->run($here . "/reportDocuments/" . session_id() . "/GRN.rptdocument");
$task->close();

$task = $birtReportEngine->createRunAndRenderTask($report);

$taskOptions = new java("org.eclipse.birt.report.engine.api.PDFRenderOption");
$outputStream = new java("java.io.ByteArrayOutputStream");
$taskOptions->setOutputStream($outputStream);
$taskOptions->setOption("pdfRenderOption.pageOverflow", "pdfRenderOption.fitToPage");
$taskOptions->setOutputFormat("pdf");

$task->setRenderOption( $taskOptions );
$task->run();
$task->close();

Close, but the second task should be a render task.

try{

$document = $birtReportEngine->openReportDocument($here .
"/reportDocuments/" . session_id() . "/GRN.rptdocument");
$task = $birtReportEngine->createRenderTask($document);
..
..

..
$task->render();
$document->close();
$task->close();
