Terracotta Platform -> Unsharable class question -> Go to message
Ok, I will have to investigate this. If source code change is the only option, the product actually does not work with default page flow applications created with BEA WebLogic Workshop. I will investigate a little bit further.

Terracotta Platform -> Unsharable class question -> Go to message
Hi!

I am working on getting my BEA Pageflow app to work with DSO. I have some challenges with the com.bea.wlw.netui.pageflow.PageFlowStack object. It gives me the following error message:

I have tried excluding the PageFlowStack class as shown below, but I still get the same error message. What am I doing wrong? Don't see how I can exclude neither Stack nor HashMap, so I am unsure of how to proceed here...

My config files is attached, and also shown here:

<?xml version="1.0" encoding="UTF-8" ?>

<!-- This is a minimal Terracotta configuration file that's just
enough to start the system.

DSO services are started by default; they require no
immediate manual configuration, although you will have to
define locks, roots, and instrumented classes, below, to
run your own applications.

JDBC services are not started by default; they require
you to configure the database-listener host and port,
below, before they can run correctly.

For more information, consult the Terracotta documentation
and/or the sample configuration files provided with the
server.

<jdbc-enabled>false</jdbc-enabled>
<dso-enabled>true</dso-enabled>

<!-- This switch affects how the server behaves in the
presence of differing configurations for your
application (the elements inside the <application>
element, below).

In the default configuration model, 'production',
the server's own local configuration is canonical:
if a client connects and has a different configuration,
it will read the server's configuration instead and
use that. (This will cause a DSO client to disconnect
and stop, because DSO clients are unable to modify
their configuration once running.)

In the 'development' configuration model, if a
client connects and has a different configuration from
server, the server accepts the client's new configuration and
uses it. Further, any currently-connected clients are
updated to match the new configuration. (Again,
for DSO, this means they will disconnect and stop.)

'development' mode allows you to modify configuration
on-the-fly more easily and have the system respond
to it automatically, while 'production' mode allows
you to be sure your configuration won't change at
runtime.

See the documentation for more details.

Terracotta for Web Sessions -> WebLogic Pageflow web app: Problem with the Global class -> Go to message
Hi!

Just added the terracotta persistence type to my weblogic.xml session descriptor in my small test web app. The web app is a BEA Pageflow web app created with BEA WebLogic Workshop.

I get the following error in my server log file when starting the page flow (before the begin action is reached):

Is there anything I can do to avoid this by adding more configuration to the terracotta config file? I am currently running only with the default config file without any modifications.

Thanks in advance,

Terracotta Platform -> DSO Server config file url question -> Go to message
Hi, thank you, worked right away :-)

Terracotta Platform -> DSO Server config file url question -> Go to message
Hi!

I have installed the terracotta server under

C:\tc2.0.3

(yes, windows..)

The config file is placed under

C:\tc2.0.3\config

Currently I'm just using the default config file produced with the start-tc-server.bat -f command.

The server successfully starts up with the following message:


C:\tc2.0.3\bin>start-tc-server -f C:\tc2.0.3\config\tc-config.xml
C:\tc2.0.3\bin>echo off
Using the Terracotta home path specified in the
TC_INSTALL_DIR environment variable, \tc2.0.3\bin\...
Using the built-in Terracotta JRE at \tc2.0.3\bin\..\jre\bin\java.exe.

2006-08-03 19:36:44,000 INFO - Terracotta Server has started up successfully, an
d is now ready for work.

My question is: What is the correct syntax for the URL to use when specifying the

-Dtc.config

startup parameter for my java app (WLS 8.1) running on the same machine as the server?

I have tried with the option

-Dtc.config=http://localhost:9515/config/tc-config.xml

but this gives me the error message

2006-08-03 19:40:02,265 INFO - This is Terracotta, version 2.0.3 as of 20060720-

alhost:9515/admin/config/tc-config.xml.)

What is the correct URL in this case?

Thanks in advance,

Regards
