Sorry but Class has method.

See in
http://jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/export/JRRtfExporter.html

The method is inherited from another class

I try with to  java("your.class.com")->ATTRIBUTE

And it still error persist and it's the same

:(

I found some people with this error in Google and with no success in
solution.

> [[c:JRRtfExporter]]->setParameter([o:JRExporterParameter], [o:JasperPrint]).
> Cause: java.lang.NoSuchMethodException:

The class JRRtfExporter (note the "c:...") doesn't contain a procedure with the name "setParameter". You probably want to invoke a setParameter method on a JRRtfExporter instance.




      

Im trying to get that in php:

/*JAVA CODE*/

JRRtfExporter exporter = new JRRtfExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, masterPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, sPathRTF);
exporter.exportReport();

/*MY PHP JAVA BRIDGE IMPLEMENTATION*/

$exportManager = new
JavaClass("net.sf.jasperreports.engine.export.JRRtfExporter");
$exportManagerParam = new
JavaClass("net.sf.jasperreports.engine.JRExporterParameter");
$outputPath = realpath(".")."/"."informe.rtf";
$exportManager->setParameter($exportManagerParam->JASPER_PRINT,$jasperPrint);
$exportManager->setParameter($exportManagerParam->OUPUT_FILE_NAME,$outputPath);
$exportManager->exportReport();

/*output*/
*Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: Invoke failed:

*¿¿HOW TO IMPLEMENT JRExporterParameter.JASPER_PRINT STATIC ATTRIBUTE IN PHP
JAVA BRIDGE???*

Thanks for your guide and help

Sounds like a bug/problem in gcc/gcj ("GNU Java"). 

Here's the relevant part from Sam Ruby's coerce/select:

	else if (c == Integer.TYPE) result[i]=new Integer(s);

When methods are invoked through reflection, Java automatically coerces an Integer to a primitive int. The code is more than 6 years old, so that I am pretty sure that it worked with Java 1.4. Since 1.5 Java this behaviour is documented (autoboxing/-unboxing).


Please either use a real Java VM or compile your Java classes with GNU gcc >= 4.2, which implements the Java 1.5 spec.

I will add this requirement (gcc >= 4.2) to the README.GCJ.

Hi,

the PHP/Java Bridge install instructions are here:

I'm trying to resolve this for 3 days, and I found solution just after I have submitted an email. The problem was I have used 192.168.1.5 (that is my pc address) instead of localhost.

Hi,

I found that this test.php
<?php
 require_once('http://192.168.1.5/JavaBridge/java/Java.inc');
 $session=java_session();

works fine if I call it from JavaBridge application in tomcat only if 
I change to:
<?php
 require_once('java/Java.inc');
 $session=java_session();
?>
but I need to use it from my application. 

Could somebody help me what did I miss to do here?

Thanks,

Hello, 

first of all thank you for your response ... but I wanted to compile the
javabridge to have the library "java.so" I will use as a module in PHP ,
look please on this page what I found to compile the javabridge:
http://www.micromegastudio.com/index.php?id=10, 30,0,0,1,0 . Otherwise
compile the source code? 

thank you in advance

Hi,

> Linux, but when execute phpize to compile javaBridge I got


Too bad, but this will stay that way. -- Please report this problem to your OS vendor, not to us.

If rpmbuild -tb php-java-bridge*.tar.gz or the debian build instructions fail, you can report this problem on this mailing list. 

Please note that the PHP/Java Bridge is pure Java, it doesn't need to be compiled against your OS or your PHP version.

> $session = java_session();

So you add a new object to the session store in each request and(!) keep the old objects referenced from a thread outside of the scope of the bridge?

someJavaObject should have been garbage collected, i.e. getParam1() should have returned null. If not, you have found the reason for the OOM.

>>then you've written a bug, I think.

Maybe! 
But the only code I have is 
$session = java_session();
$session->put("param1", someJavaObject);

On the other page I am doing
$someJavaObject = $session->get("param1");

That is all I have. 2 lines of code for the session in php and one line in
the second php.

BTW, $someJavaObject would be temporarily referenced by many threads on the
backend in the subsequent calls. Could that be the source of the problem?

>>It is not possible to keep the state w/o using java_session(), at least
not reliably.

As I mentioned earlier, I have apache http server and tomcat. Instead of
using java_session, I am using the session_id() within the apache server and
against that id I am storing a data structure in the backend.
So, on the first page I am doing
$sessionid=session_id();
$myBackendHodler.storeParam1($sessionid, someJavaObject);

On the second page I am doing
$sessionid=session_id();
$someJavaObject = $myBackendHodler.getParam1($sessionid);

Let me know if you think that is reliable. 

>> Please see our FAQ entry "How does the bridge handle OutOfMemoryErrors?"
for details.

I have gone through it but will go over it one more time.

not necessary. Your bug report is here: http://bugs.php.net/bug.php?id=46917

Hi Jost,

Really appreciate you taking time to write lengthy replies.

Another thing that I observed was I was using java_session(). In that case
the memory on the Tomcat server kept increasing with every hit on the page.
Because of that the tomcat server went out of memory very quickly.

I stopped using the java_session to verify that and found that memory didn't
go up that much. I have found a way to get my work done without using
java_session.

Do you know why using a java_session() could create such problem?

Thanks

Subject: Re: [Php-java-bridge-users] protocol error: ,Invalid document end
at col 16. Check the back end logforOutOfMemoryErrors

Hi Nathan,

I am afraid but this problem cannot be fixed on application level.

PHP/windows contains code to detect a broken connection, but it fails to
detect it if the back end has destroyed the channel w/o waiting for the
client. If the front end doesn't explicitly close the connection, the
connection goes back to the pool and PHP/windows returns it the next time
pfsockopen() is called. 

The PHP/Java Bridge back end destroys a channel only if it has to recover
from a java.lang.OutOfMemoryError. 

Unfortunately this means that the bridge cannot recover from an OutOfMemory
condition automatically, which is certainly not what we want.

PHP/Java Bridge version 5.4.1 contains code which explicitly destroys a
persistent connection if a protocol error occurred (it calls
"dieWithPersistentConnection(errorCode)" instead of simply "die(errorCode)")
>From the NEWS file:

Version 5.4.1

* If PHP is used within a J2EE server or servlet engine the option
  JAVA_PERSISTENT_SERVLET_CONNECTIONS is set. This means that the
  servlet option fcgi_children (see WEB-INF/web.xml) must be less than
  or equal to the servlet engine's thread pool size. It defaults to
  5. The smallest thread pool we've seen is the thread pool of the Sun
  J2EE server version 9, with 5 entries.

* If PHP is used within Apache or IIS via the java.so or
  php_java.dll the option JAVA_PERSISTENT_SERVLET_CONNECTIONS is
  set. This means that Apache/IIS "maxChilds" must be less than or
  equal to the servlet engine or J2EE server's "maxThreads" value,
  otherwise the additional PHP executables will hang. On Fedora and
  RedHat Linux we have verified that Tomcat's maxThreads == Apache
  maxChilds. If you're unsure, do not use the php_java.dll/java.so.

* If a windows Java back end is destroyed via the task manager, a
  PHP/windows front end keeps using the old persistent connections to
  the back end. If your Java back end requires a reboot (usually
  because new software has been installed), reboot the entire windows
  machine to avoid problems with old resources. Or use a unix machine
  as the HTTP server front end instead.

* All options can now be set on the command line. Example:

    php-cgi -djava.persistent_servlet_connections=On test.php



However, the fundamental problem, that PHP cannot detect broken connections
on windows, still exists. Please report this problem to the PHP maintainers.

Jost Bökemeier

Hi,

I have tested the releases on WinXP and WS 2008 with the PHP version included in the .war file, and I am quite sure that these versions reopen the connection after the back end has been restarted.


> Unfortunately I do not have a packet sniffer.

Can you please add

  define ("JAVA_DEBUG", true);

before including java/Java.inc and post the result html page?

It will increase the latency; opening a new connection for each request costs a few hundred microseconds.

Hi Jost,

The operating system is Windows Server 2003 R2. PHP version is 5.2.6.

Unfortunately I do not have a packet sniffer.

If I replace all pfsockopen with fsockopen, what is the downside of it? What
potential problems could I run into?

Once again, thanks for taking the time to reply.

-Ajit

Hi,

sounds like PHP's pfsockopen() cannot detect a broken connection on some
operating systems. A workaround is to use fsockopen() instead (open
java/Java.inc and replace all pfsockopen() occurences). 

Which operating system and which PHP version are you using?

Do you have a packet sniffer installed to debug this problem? If so, please
file a bug report to the PHP maintainers (=>fbugs.php.net) and attach the
network packets to that bug report.

I've had this same problem.  (protocol error when either Tomcat or Apache is restarted and no errors on the back end) Basically, what I end up having to do is restart the whole server whenever I change anything related to Java.  Restarting Tomcat and Apache separately didn't fix the problem for me.  Thankfully, I rarely have to add or modify java classes.  It would be nice not to have to bring the server down though.  It takes about 7 minutes for the server to boot and everything to come back up.  It's workable, but definitely less than ideal.

Hi Jost,

Thanks for taking the time to reply.

I did read the FAQ before and I looked in my Tomcat, there were no errors.
Another thing I noted is that this problem goes away just by restarting
Apache http server. If it were a tomcat issue how would restarting Apache
HTTP server help?

One more thing I noted is that if I restart Tomcat, then I have to restart
Apache HTTP server as well otherwise I keep getting this error.

Last point - This problem is more observed when Apache HTTP servers are
running on separate boxes. When they run on the same box the problem happens
less frequently.

Again, any insight is appreciated.

Thanks
-Ajit
