Working fine on Tomcat 5.0 but not on 5.5.7
Hi Friends,
I have this simple method which works fine on my system(Tomcat 5.0,jdk
1.5)..but not on the server(Tomcat 5.5.7,jdk1.5).Can someone explain me why:
-
String syear = null;
int selectedYear = 0;
try{
syear = request.getParameter(year);
if (syear != null){
selectedYear = Integer.parseInt(syear);
session.setAttribute(syear_sess,new Integer(selectedYear));
}
else{
if(session.getAttribute(syear_sess) != null)
selectedYear = ((Integer)session.getAttribute(syear_sess)).intValue();
else
{
syear = 2005;
selectedYear = Integer.parseInt(syear);
}
}
}catch (IllegalArgumentException _e){
throw new Exception(selectedYear error);
}
--
year is a combo box name.The error this code throws is:
--

Type mismatch: cannot convert from long to Long
Hi Friends, I went for help in the java forums,but I think you might help me better with this.I have a jsp that runs fine on my system,but when i upload it on the server it starts throwing this error: Generated servlet error: Type mismatch: cannot convert from long to Long And the other thing is when i undeploy a war file on the server(5.5.7),the entry still remains there,altough the running status turns to false...but on my system(5.0)..when i undeploy a file,the entry too is deleted.Might be,the server is not refllecting the changes i made to my JSP and loading the same old JSP.I dont know what the problem is and what to do??Can someone help me please??

Re: AW: Type mismatch: cannot convert from long to Long
thanks christoph, I think the casting is fine...coz i have shown the code to the java guys.And even if i restart the server,the entries still remains there and works fine...i.e its not undeploying it,thought it shows the message OK - Undeployed application at context path /xxx And the other thing is when i restart the server it doesnt works properly unless i explictily kill the java processes. And finally can you please tell me in which file the autodeploy=true entry goes.This work is really important for me,any help wud be appreciated On Tue, 01 Feb 2005 [EMAIL PROTECTED] wrote : autodeploying war files has to be configured in the webserver. It seems that it isn't. Perhaps you have an acces to the configurationfile of your productive tomcat, than you can add the host element an attribute like autoDeploy=true, else, try to restart the server. The other thing, the exeption that you get, seems like a wrong cast in your jsp. Perhaps you have another version of tomcat than your provider.

I guess this is a BUG!!!
Can anyone please tell me if it's a BUGi think it is one. I'm using Tomcat5.5.7 and i am not able to undeploy the file,it shows that the file is undeployed and loads the new file.But it still keeps showing the old file contents.Can anyone tell me what's the fix?? Secondly,the server does not restarts until I explicitly use the kill proccess_id for the java process. Please enlighten me.
Specifying context details in web.xml
Hi Friends, I need to ask you guys that is it possible that I can move the context details from my server.xml to web.xml.Like when i make a war,i want that i should specify the database url,driver,username,password etc. details .Presently i have 2 contexts(one for alpha databse other for the live one)in the server.xml file in the server.But i need these details in my web.xml.Can you tell me if I can do soany help would be appreciated. Thanks
Dynamic Connection
Hi Friends, I want to dynamically configure the database,username and password settings,instead of putting them in conf/server.xml.In other words,I dont know beforehand which database to use, with which username and password.It all depends upon the person and the machine from which it tries to make a connection.In yet another words,I just need to do what the BasicDataSource is doing i.e get the connection details before making a connection.I am not quite sure if you got my point,but this is what i've been asked to do and I have no clue as to where to go or what to do.If anyone of you got my point,please help me. Thanks
Re: Re: Dynamic Connection
Thanks David, I am already using the Datasource class to vreate a connection.For eg. Context ctx = (Context) init.lookup(java:comp/env); ds = (DataSource) ctx.lookup(jdbc/abc); The problem is that to know which database is selected I am trying to do exactly what the BasicDataSource class does,if that's possible.Is there any way by which I can read the environment variables that TOMCAT has setplease help. On Thu, 27 Jan 2005 David Smith wrote : Sounds like you can just about totally abandon the idea of using any pooling functions provided by DBCP. If I were designing, I'd construct an object that implements javax.sql.DataSource and store it in the session as soon as you know what db is being used. Then on each request, get the DS from the session and use it as needed. Just be sure you only store the DS in the session -- don't store the connections. I'm sure there are other ideas out there as well. --David micky none wrote: Hi Friends, I want to dynamically configure the database,username and password settings,instead of putting them in conf/server.xml.In other words,I dont know beforehand which database to use, with which username and password.It all depends upon the person and the machine from which it tries to make a connection.In yet another words,I just need to do what the BasicDataSource is doing i.e get the connection details before making a connection.I am not quite sure if you got my point,but this is what i've been asked to do and I have no clue as to where to go or what to do.If anyone of you got my point,please help me.

Thanks Doug,Harry and rest of my friends, After going thru the links ,I was able to make it work.Before I end this thread I just want to clarify some doubts.I am querying a database ,but I have some delay getting back the results.Now I want to check if the query is causing the delay or am I going wrong with allocating connections.So,I want to log all my program steps in a log file,can u just tell me what code I have to add and where??
