| SettingStore not working between AppSvr cycles [message #1102984] |

I have some issues using SettingStore, which should be storing Cookies for retrieval later. The behaviour varies a little depending upon browser, but IE is worst, so will use that as the example...
If I have my RAP application running (from within Eclipse, or standalone OSGi, or WAR deployed in some other container), I use SettingStore to save a key pair.
- Within the same session I can retrieve the value ok.
- If I REFRESH the browser to start again, it also works ok and value is retrieved.
- If I open a 2nd IE, this one also retrieves the value ok.
However:
- If I close all IE instances, open a new one, it does NOT retrieve ok
In Chrome and Firefox the above behaviour works as expected... but...
In all types of browsers, if I cycle the AppServer, none of them retrieve the value - it is as if there is no cookie stored at all.
Any idea whether this is a bug in RAP, or some other setting somewhere?
The behaviour is the same for RAP 2.1 and 2.2 M1 nightly from earlier this week.
The code is simple:
to store the value:
myValue = RWT.getSettingStore().getAttribute("myProperty");
to retrieve the key value:
RWT.getSettingStore().setAttribute("myProperty", myValue);
Thanks,
John

Hi John,
I did some testing by restating the Jetty from my IDE. The file with the
settings is stored here:
...Workspace\.metadata\.plugins\org.eclipse.pde.core\<launch config
name>\org.eclipse.osgi\bundles\6\data\jettywork\pid_1544803905\proxytemp\hc_8377580\org.eclipse.rap.rwt.service.FileSettingStore\<storeID>
When Jetty is restarted the directory "proxytemp" is deleted and created
again, where the subfolder "hc_8377580" has a different name. As a
result the file with settings is gone.
Look at FileSettingStoreFactory#selectWorkingDir() for details how this
folder is selected/created. In this case the folder is obtained from
servlet context tempDir, which chages all the time.
If you want a fixed directory you could set it as servlet context init
attribute (see FileSettingStore.FILE_SETTING_STORE_DIR).
HTH,
Ivan

Hi Ivan,
Not had a chance to look further into this, but finally now looking again.
Do you have an example of how to specify this init parm in the web.xml?
I've added:
...
<init-param>
<param-name>FileSettingStore#FILE_SETTING_STORE_DIR</param-name>
<param-value>c:/temp/RapideWorkDir/</param-value>
</init-param>
...
...as an initial test, but it isn't clear whether it is being used. Certainly a cycle of the appsvr still results in the RWT.getSettingStore().getAttribute("myAttribute") returning nothing, as if it has all been wiped as, same as previously.
Sorry if I'm being thick about the format of the parm in the xml, but I've not played with anything inside the web.xml before, so your help greatly appreciated.
Assuming I'm close the having it working, how does the value itself work? Does it have to be an explicit path, or can it be relative to something?
Thanks, John (maybe barking up the wrong tree)

Hi John,
the value of FileSettingStore#FILE_SETTING_STORE_DIR parameter is
"org.eclipse.rap.rwt.service.FileSettingStore.dir".
....
<init-param>
<param-name>org.eclipse.rap.rwt.service.FileSettingStore.dir</param-name>
<param-value>c:/temp/RapideWorkDir/</param-value>
</init-param>
....
HTH,
Ivan
