Re: Certificate issued by GeoTrust Global CA is not appearing at client browser's side

[Ashish Kulkarni]

I had to deal with this issue in Websphere, got Thwate certificate and no
matter what i was not able to get the primary and secondary certificate to
work in IE browser, only in Firefox and chrome, finally i got a certificate
from Verisign and it works well in IE and chrome but not in firefox, this
certificate business is very murky with these companies making deals with
browser companies and making our life difficult,
I bet If you add the primary and intermediate certificate to IE browser it
will work fine, if there is another web service who needs to call this then
that web service must know all the 3 certificates to authenticate your
certificate

Re: Save session information in Memory database

[Ashish Kulkarni]

Hi

The problem is we are running on 32 bit system and cannot go beyond 1.5 GB
or ram, because of some clients limitations.

Is it possible to save session in database, instead of heap memory which
would help us, the speed is ok if it slows down a little,
That is why i was looking at in memory database instead or conventional
database

Re: Save session information in Memory database

[Ashish Kulkarni]

What do you mean it will slow down?

We have an application which saves about 5 MB of data in session when user
is working with some portion of application, so when about 200 users login
we go about 1 GB of ram and Tomcat starts running out of heap memory, as all
the session data goes in heap memory,

So i was hoping if i can persist the data in database, then i can free up
some heap memory from tomcat.

Will this work? or tomcat will have session in Heap Memory only even if i
prefer to persist to write it in database

I have deployed 3 applications in tomcat, is there a way to setup startup
sequence of these applications in tomcat, for example if i have test, test1,
test2 as application then i would like to start test2 first, test1 second
and test last, as test needs some information from test1.

Any ideas

How to retrieve persisted session

[Ashish Kulkarni]

Hi
I have configured my tomcat to save session in database as per
documentation, and it works as expected i can see the session is saved in
database,
Now if the user closes the browser, and then reopens i dont want to show the
login screen but get the session from database and go to the last visited
page,
how can i retrieve this session from database,
Normally our application checks for session, and a flag in session, if the
flag is on then user id logged in, but in my current application if i open
new browser window, it creates a new session,

any ideas

1 is it possible to do so?

Re: Configure tomcat in my development environment, and save session across restart

[Ashish Kulkarni]

Hi
Is it possible to find from log files or some where, what is preventing from
tomcat not able to persist sessions, all the classes saved in tomcat
are serialized, they implement implements Serializable.
where does tomcat save this serialized data file on PC, i want to see if
this is created
I have switched from tomcat plugin and using tomcat directly and still have
this error, i created a JSP which simply dumps all the objects in session on
webpage, before saving any class i have 2 objects in session, as soon as i
save the class and tomcat restarts and i refresh this jsp page, there are no
objects in session class.

Configure tomcat in my development environment, and save session across restart

[Ashish Kulkarni]

Hi
I use tomcat 5.5.28 for my development in eclipse, when ever i change any
class it restarts my tomcat and i loose my session, so i have to go through
login process to get the session.
Is it possible to save this session across restarts, it would be great and
save me a lot of time in development

I was reading about manager in tomcat, but did not figure out how to do it,
is there any document or example of configuring this manager,

http://tomcat.apache.org/tomcat-5.5-doc/config/manager.html

Error starting static Resources, With Network drive

[Ashish Kulkarni]

Hi
I am running tomcat on Windows XP, i have mapped a network drive to this PC
running Tomcat.
Under \conf\Catalina\localhost i created a xml file for specifying document
root
This XML file contains following code




WhereK:\\myproject\WebRoot\\ is the network drive,
I am getting following error when i start tomcat
EVERE: Error starting static Resources
java.lang.IllegalArgumentException: Document base K:\myproject\WebRoot does
not exist or is not a readable directory
at
org.apache.naming.resources.FileDirContext.setDocBase(FileDirContext.java:140)
at
org.apache.catalina.core.StandardContext.resourcesStart(StandardContext.java:3848)
at org.apache.catalina.core.StandardContext.start(StandardContext.java:4019)
at
org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:759)

at
org.apache.catalina.startup.HostConfig.deployDescriptor(HostConfig.java:608)
at
org.apache.catalina.startup.HostConfig.deployDescriptors(HostConfig.java:535)

If i have the same docBase to local drive like C:\\myproject\WebRoot\\
Then it works,
What may be the reason, is it possible to do so or not?

you can configure when tomcat write the log, but by default it is the
same.

Is there any step by step document of doing this


I don't think, there are some information but is not explicit.
