Development -> Ping servlet - Is the application server up and running? -> Go to message
Hi Björn,

thank you for your quick response.

No problem, we can implement such a servlet.

The ¡Hola mundo! in casabac was nice and useful.

Kind regards and have a nice weekend,

Development -> Ping servlet - Is the application server up and running? -> Go to message
Hi,

has CaptainCasa any "PingServlet" which just says "Hello"?
Our load balancer needs an URL to check if the application server is still alive, up and running.

It is similar to the "SELECT 1 FROM DUAL" request to check if the connection to the Oracle database server is ok.

The call should be cheap with respect to server resources.

Development -> CC as Applet: Open Modal Popup prevents Starting other Firefox Browsers -> Go to message
OK.

Firefox V 24.0 is partly fixed:
Now it is at least possible to start another browser instance (second firefox window).

But all other tabs in the first firefox window remain unreachable.
The opened dialog seems to be modal for the whole firefox window, not only for the current tab.

Kind regards,
MaMü
Deployment -> How to use Apache HTTP Server as LoadBalancer with CaptainCasa? -> Go to message
Hi Björn,

thank you for your helpful hints.

Apache Web Server is now running as load balancer on my box.

Basically I added in httpd.conf the following lines:

Code:
 LoadModule  proxy_module           modules/mod_proxy.so
 LoadModule  proxy_balancer_module  modules/mod_proxy_balancer.so
 LoadModule  proxy_http_module      modules/mod_proxy_http.so
         
 ProxyPass  /act3_explorer  <a href="balancer://credManCluster" target="_blank" rel="nofollow">balancer://credManCluster</a>  nofailover=On  stickysession=jsessionid
         
 <Proxy  <a href="balancer://credManCluster>" target="_blank" rel="nofollow">balancer://credManCluster></a>
     BalancerMember  <a href="http://host1/act3_explorer" target="_blank" rel="nofollow">http://host1/act3_explorer</a>  route=tc1
     BalancerMember  <a href="http://host2/act3_explorer" target="_blank" rel="nofollow">http://host2/act3_explorer</a>  route=tc2
     BalancerMember  <a href="http://host3/act3_explorer" target="_blank" rel="nofollow">http://host3/act3_explorer</a>  route=tc3
 </Proxy>


In the server.xml files of the three tomcats on host1..3 I had to add
- the attributes proxyName and proxyPort to the Connector element and
- the attribute jvmRoute to the Engine element.

Now it is time to separate static and dynamic content.

Is there any documentation about it?
Which files are needed on the tomcats, which may be moved to the web server,
which patterns can I use to separate the processing of static and dynamic content in httpd.conf?

Kind regards,
MaMue
Development -> CC as Applet: Open Modal Popup prevents Starting other Firefox Browsers -> Go to message
Hi,

if I use our CaptainCasa application as applet in Firefox 23.0.1 and open a modal popup,
then I can't switch to other tabs in the same browser window.
If I start another instance of Firefox, then it doesn't respond until I close the popup in the first Firefox.

I have tested this with Firefox 23.0.1 on Windows 8 and on Windows XP.
Also with Internet Explorer there seems to be similar problems.

Any ideas?

Kind regards,
MaMue
Deployment -> How to use Apache HTTP Server as LoadBalancer with CaptainCasa? -> Go to message
First I tried the first sample of http://httpd.apache.org/docs/2.2/mod/mod_proxy_balancer.html
But this did not work:
The requests of a single client were routed alternately to the two tomcats behind the HTTP server.
It seems that Cookies are not supported by CaptainCasa (neither by jnlp nor by applet clients).
Therefore the web server had no chance to route the requests to their already running sessions.

  • Is there a chance to activate cookie handling in CaptainCasa?
  • Is there a chance to balance HTTP requests as shown by the example above?
  • If AJP is required to get CaptainCasa working, is it also required to separate static and dynamic content?
  • Should I use mod_proxy or mod_jk?
  • Is there a description of all steps needed to get CaptainCasa applications working with mod_proxy or mod_jk?

    Kind regards,

    • Development -> jMeter: Problem with ccautocomplete -> Go to message
    Muchas gracias!

    Development -> jMeter: Problem with ccautocomplete -> Go to message
    Hi Björn,

    the header fields of the response do not contain some info how the response is encoded. Therefore jMeter does not analyze the response. If I smuggle the following header into the response, jMeter shows and analyzes the response:
    Content-Type: text/plain;charset=UTF-8

    Is it possible to add this kind of header by default to the autocompletion responses?

    Best regards,

    Development -> jMeter: Problem with ccautocomplete -> Go to message
    I assume you mean the large number in .../jsp/AC_1354621995534_38.ccautocomplete...

    This number is no problem.
    We capture this number from the response before.
    We find the number in in the valuesurl attribute of the autocomplete element in the previous response.

    With this url we call the server - which builds the proposals correctly, as we detected while debugging. But the result is not received by the client.
    At least jMeter displays an empty response body...

    Best regards,
    MaMue
    Development -> jMeter: Problem with ccautocomplete -> Go to message
    Hi Björn,

    debugging the test shows that AutoCompleteServlet.doGet() is called correctly and the Writer of the response object is called repeatedly with the correct results. The doGet() call returns normally, i.e. without exception.

    Do you have any idea why the jMeter tool sees no response content?

    Best regards,

    Development -> jMeter: Problem with ccautocomplete -> Go to message
    Hi Björn,

    we try to test the ccautocomplete feature with jMeter, but if we run the test, the response remain empty.
    Do you have any idea?

    Our request looks like e.g.
    GET http://10.0.0.175:8087/act3_explorer/jsp/AC_1354621995534_38.ccautocomplete;jsessionid=44430A20BC6535C28F3321A6DCC3831D?SEARCHSTRING=F HTTP/1.1

    We have extracted the "AC_1354621995534_38" from the prior response.
    Also the jsessionid is extracted and inserted dynamically.

    Do you have any idea why the response of this request remains empty on test runs?

    Best regards,

    Development -> t:formattedfield with format="long" fails if you enter Long.MAX_VALUE + 1 or greater -> Go to message
    Hi Björn,

    thanks for checking and fixing.
    The fix is not urgent.
    We found the problem during monkey testing.

    Development -> t:formattedfield with format="long" fails if you enter Long.MAX_VALUE + 1 or greater -> Go to message
    Hi Björn,

    if I use a <t:formattedfield format="long" ... /> and if I enter the value 9.223.372.036.854.775.808 or greater and if I leave the edit field, then there will be a java.lang.IllegalArgumentException in javax.el.BeanELResolver.setValue() on client side.
    The value above is 2^63 which is java.lang.Long.MAX_VALUE + 1.

    Is there any chance to solve this problem?

    Kind regards,

    Hi Captain,

    since some day we noticed hundreds of lines like the following in the Java console:

    What do they mean?
    Is there a chance to disable these loggings?
