php-java-bridge-users Mailing List for PHP/Java Bridge

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

Hi,

this error message means that your .NET or Java VM has problems.
Please see our FAQ "What does a "protocol error ..." mean?" for details.

Hi All,

 

I have the following setup

I have Apache 2.2 and php 5.2 as part of WAMP installation.

I have tomcat running on another server. I have JavaBridge installed within
my application in Tomcat.

 

When I try to run my php page that calls the Java Bridge and I get the
following error

 

protocol error: , Invalid document end at col 16. Check the back end log for
OutOfMemoryErrors...

 

I have no idea why this could be happening.

 

Any help on this is highly appreciated.

 

Thanks

-Ajit

It means that the method Hits.doc expects an int as argument but was
given a string. You should explicitly convert the value in PHP using
intval for example.

If you plan to use PHP/Java Bridge heavily, I recommend you learn to
decode such exception reports because they will provide the only clue
as to what's wrong with your code!
