Request Handling

[zzpprk]

Hi

I am new here and new to JBoss AS.

Suppose you have two requests for the same web service hosted by JBoss. We will call them A and B. What will happen if B comes-in while A is still being processed? Will JBoss wait for A to complete before processing B or will it start processing B immediatly (i.e. A and B will be processed in parallel)?

Regards

It's a normal HTTP requets that will be processed in a separate thread.

Thanks. Is there a limit to the number of concurrent threads that can be created?

[nickarls]

I would assume JBossWeb has some configurable max concurrent connections settings like Tomcats have

[zzpprk]

Anybody know what that maximum is and how it can be set?

Yes, the embedded Tomcat server in JBoss has settings for both HTTP and AJP.

Look at tip 13 at: http://www.mastertheboss.com/jboss-server/113-jboss-performance-tuning-1.html?start=2

If you tell me exact wich version af JBoss are you running I can point out where the "server.xml" file is located?

[zzpprk]

I am running JBoss on a Unix platform. How can I check the version?

[welle]

There may be a readme.html in the server installation directory.

Tip of the day. Look in the logfile "boot.log"

[zzpprk]

Yes there is.

I am running JBoss 5.1.0.GA.

Where is that "server.xml" file?

[welle]

$JBOSS_HOME/server/XXX/deploy/jbossweb.sar/server.xml

XXX = The setup you are using!

Thanks.

I need a bit more help in understanding this file.

We connect to the web service on port 9000. The following extract is from that file. Does it mean that the request will be redirected to port 9001?

      <!-- A HTTP/1.1 Connector on port 9000 -->

      <Connector protocol="HTTP/1.1" port="9000" address="${jboss.bind.address}"

               connectionTimeout="20000" redirectPort="9001" />

And foor port 9001, I have the following. Does that mean that as maximum of 150 requests will be handled at the same time?

      <!-- SSL/TLS Connector configuration using the admin devl guide keystore -->

      <Connector port="9001" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https"

        secure="true"  clientAuth="false" strategy="ms" address="${jboss.bind.address}"

        keystoreFile="${jboss.server.home.dir}/conf/sapws.keystore" keystorePass="SAP4ever"

        truststoreFile="${jboss.server.home.dir}/conf/sapws.keystore" truststorePass="SAP4ever"

    sslProtocol="TLS"/>
