pd4ml transform tag renders weird characters

#27142

I’m using pd4ml to generate pdf using pd4ml taglib. The jsp is rendered with wired characters instead of showing pdf. we are using tiles for rendering jsp.
ex: %PDF-1.4 %Çåôåð 1 0 obj << /Filter /FlateDecode /Length 940 >> stream xÚÅWmsÚ8þŒŖ™»IfˆcùÇÌäKBҒÒÐë]››aPk[Ž$pé¯ïʐÉÌ&×aÒJÚgß´»Ü[?Á ë÷9“Š‹¼^D` nuß>’‰ÚÎ_$@úõí#ùÏQ*¡mÜ»ä)–Ç”áù¤çqéŠ)s¡×í@ö:;»ùcüûÕäcÿˆ]ßýY÷ü”ïÑnؽߜò+åïßN¿Î’_§Þdø.|E#ÉèõHEô“¯L„tòâÁÊ‚^€ë>@Ž‡24óxq>ì[Ž„8ø9ZÍ«x:ÎÌIÊsP3˅+‹@iٮƻ×O–rRã„áãàôÚÁÌüÐ7{ÌoâŽ?Îj¬v–¸{o5ÈRóãEHE-gC«aÀ&VãøRäú KçL󘝉4!àžÀpl5†hObï;„ág«q1´njµ¿Ýºê†¤†ºÈÙ_jz1³Xó9ƒnj}*ã)¸ w¨z]ñ‰ão%ÿpÊÆ3)®üí·[&ç

The “garbage” is PDF bytes, shown as plain text. Obviously “Content-type” HTTP response header is overridden with a wrong value. Check the server/webapp setting.

Thanks for your response.
I have changed the weblogic server start parameter to add
-Dweblogic.webservice.i18n.charset=utf-8 and restarted the server. No luck.

then I added the below parameter and restarted the server.
-Dfile.encoding=utf8

Weblogic Domain path-> bin folder -> setDomainEnv.sh under JAVA_OPTS added the below variable.
-Dfile.encoding=utf8.

Still it is displaying the same characters. Plz help me what could be the problem.

Thanks,

It is not about charset / character encoding.

Your webapp should send “Content-type: application/pdf” with HTTP response.

PD4ML taglib implicitly sets the correct HTTP header. (Do you use PD4ML taglib?)
It your case it seems to be overridden with “Content-type: text/plain“.

This is the code
<%@ taglib prefix="pd4ml" uri="/WEB-INF/taglib/pd4ml.tld"%>

After removing PD4ml transform tags response in jsp is:

You published as “response” returned HTTP content, which looks correct.

HTTP server also sends so-called “HTTP Header”, which should have “Content-type: application/pdf” entry.

Your JSP code also seems to be ok. So first I would suspect your web application has a config mapping “JSP -> plain/text”, and the configuration overrides “Content-type: application/pdf” set by PD4ML taglib.
