Hi
I am having a major problem debugging my JSP's in Tomcat 4.1.12. We are making
some changes to an application already working on Model 1 architecture.
We are using JSP's , JavaBeans and an SQL Server D/B.It was deployed on Tomcat 3.2.3
and was working fine. I just wanted to make the changes and test it on Tomcat 4.1.12.
IN Tomcat 3.2.3 if an error was encountered by the java bean , while making a JDBC call
or executing a query the name of the bean and the line number would be displayed on the error console . It was easy to look into the bean and make changes.
I dont see the name of the class file or the method name in Tomcat 4.I also tried changing the logging verbosity levels in server.xml.The console shows a lot of connectors and adapters but does not ever give clue where the problem is.
Can some one tell me , is this feature disabled or am I missing something.

Thanks in Advance.

Have you looked in catalina.out ?

Also, if you configure your web application in server.xml, you can specify your own log filename for that web application. The examples in server.xml, combined with the documentation should help. http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/logger.html

Hi
This is my server.xml
<!-- Tomcat Root Context -->

<Context path="" docBase="oss" debug="0"
reloadable="true" />

<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_DBOSS_log." suffix=".txt"
verbosity="4" timestamp="true"/>
<Resource name="jdbc/myoracle" auth="Container"
scope="Shareable" type="javax.sql.DataSource"/>

<ResourceParams name="jdbc/myoracle">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>
</parameter>
<parameter> <name>validationQuery</name>
<value>Select sysdate from Dual</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc racle:thin:@andromeda.worlddata.com:1521:wdiora</value>
</parameter>
<parameter>
<name>username</name>
<value>w_provision</value>
</parameter>
<parameter>
<name>password</name>
<value>w_provision</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>20</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>10</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>-1</value>
</parameter>
</ResourceParams>

The looging is done to the file I have mentioned in the server.xml but it does not show the class and method responsible for the error.
I am not using any LOG API for the logging since this application is already in production and we were making some changes for it.
Thanks
Ram
