Re: Forms authentication without cookies in 6.0.33

This configuration has been working as expected under Tomcat 6.0.32 and earlier. On upgrading to Tomcat 6.0.33 or 6.0.35 this combination no longer works as expected. Specifically, when a user initially submits the login form they are immediately returned back to the form-login-page. Submitting the login form a second time allows them to log in. The only difference I have been able to spot between the first and second form submission is for the second submission the request attribute javax.servlet.forward.request_uri now has the jsessionid appended to the URL. After a bit of reading I'm not sure if this change is a bug, perhaps introduced by the changes to path parameter handling as mentioned in these threads: http://markmail.org/thread/2yzusfukitalkhyx http://tomcat.markmail.org/thread/ykx72wcuzcmiyujz Or if we are using an unsupported configuration which is suggested by section SRV.12.5.3.1 of the Servlet specification v2.5. Could someone please clarify if Tomcat supports forms authentication without cookies? If it is intended to be a supported configuration I'm happy to submit a bug report and can provided a simple standalone test app to reproduce the problem. Form auth should work regardless of where the session id lives. Is the login form an HTML or JSP page? A session must be created before you can login, it sounds like Tomcat isn't seeing one during the first login. p Thanks, Brett.

/wintouch/tomcat/lib/catalina.jar exists. I had to FTP it elsewhere

exactly the same as those for /wintouch/tomcat/bin/bootstrap.jar.

- if catalina.jar is not in /wintouch/tomcat/lib or it is not

- if catalina.properties is not in /wintouch/tomcat/conf, or it is
not readable, or the entries for the server.loader or common.loader
are broken
- the start scripts do not set -Dcatalina.base=/wintouch/tomcat/ and
-Dcatalina.home=/wintouch/tomcat/ when starting the JVM
- you are changing the place of the used properties file by giving a
non-default value in the system property -Dcatalina.config during
startup.
Everything looks like it's in the right place, undamaged, and without
authority issues.
Perhaps the IBM JDK6 has some bugs running on V5R4?
Some other things you might do to shed more light on this:
- Add these lines to the end of conf/logging.properties:
org.apache.catalina.startup.Bootstrap.level = ALL
org.apache.catalina.startup.ClassLoaderFactory.level = ALL
Then stop/start Tomcat. You should see a log entry like:
location X is file:/wintouch/tomcat/lib/catalina.jar
- If you do see an entry as above try compiling and running the
following from /wintouch/tomcat which tests finding a class:
BEGIN
import java.io.File;
import java.net.URL;
import java.net.URLClassLoader;
public class FindClass {
public static void main(String[] args) {
try {
URLClassLoader loader = new URLClassLoader(
new URL[] {new
File(/wintouch/tomcat/lib/catalina.jar).toURI().toURL()});
loader.loadClass(args[0]);
System.out.println(URLClassLoader found class '
+args[0] +');
}
catch (Exception e) {
e.printStackTrace();
}
}
}
END
* Save this to FindClass.java in /wintouch/tomcat
* Compile it: javac FindClass.java (or compile on another machine
and copy the resulting .class file)
* Run it: java -cp . FindClass org.apache.catalina.startup.Catalina
If this fails then my guess would be that there's a JDK6 problem on V5R4
or there's a problem with your catalina.jar. If it succeeds then some
Tomcat file(s) aren't as correct and/or authorized as you think they are
-- or you're leaving out some other important factor.

Re: java.sql.SQLException: No more data to read from socket
- Original Message - Daniel, It is a web application. I was just referring to the java code in the webapplication. This is how we retrieve the connection Class.forName(driver); ObjectPool connectionPool = new GenericObjectPool(null); ConnectionFactory connectionFactory = new DriverManagerConnectionFactory(connectionURI,userName,password); PoolableConnectionFactory poolableConnectionFactory = new PoolableConnectionFactory(connectionFactory,connectionPool,null,null,defaultReadOnly,defaultAutoCommit); coDataSource = new PoolingDataSource(connectionPool); } coDataSource is a static object and a connection is obtained whenever needed ,using coDataSource.getConnection() This doesn't look like a Tomcat issue. Your app is maintaining its own connection pool, it is not using one provided by Tomcat. I would suggest that you talk with your developers and see if they can help you.

Do you knoe what is the root cause of this issue It's hard to say since you have not answered the questions from my previous email, you have not posted your data source configuration and you have only posted a partial stack trace. Nevertheless, I will venture a guess. *If* you are in fact restarting your Oracle database then that would disconnect any persistent connections maintained by the connection pool. Given that your connection pool would contain a bunch of connections which have been disconnected, you would either need to restart Tomcat (which will create a fresh connection pool) or configure your connection pool to find and replace the closed connections (hence the suggestion to use a validationQuery). That's just a guess though, I do not believe that the amount of information that you have provided is sufficient to give you an exact answer.

I suspect that whene DB is getting restarted, Are you restarting the Oracle database without restarting your Tomcat instance? Depending on how your application gets a database connection this could be an issue. the idle connections are being removed. Are you using Tomcat DataSource to manage your connections? If so, please include your Resource/ tag. Not sure how we can avoid this situation If you are using a DataSource, you could try adding validation. With DBCP this is done by adding a validationQuery option.

While the exception is showing Oracle, which certainly appears to be the culprit, the user might be able to mitigate the issue with a configuration option like validationQuery. Unfortunately the user is not defining a resource in Tomcat, so it makes it difficult to instruct him how to try adding such an option.

Location of Tomcat 7 jvm defualt settings...
Hi All, Does anyone know the location of the default jvm settings for Tomcat 7 if the JAVA_OPTS env variable for windows is not specified? Also, does anyone know what the recommended settings to start with for say Oracle 64-bit jvm and Tomcat 7? For -Xss it used to be -Xss126k for 32-bit jvm but I am wondering for 64-bit if I should startout with -Xss256k instead. Is there an updated document for Tomcat 7 performance tuning somewhere especially for 64-bit jvm since that is quickly becoming the standard for server side servlet containers. Thanks, -Tony

Thanks Charles I have found documention for all the below from the Tomcat group but seemed somewhat outdated. Mark Thomas's name seemed dominant in most of the presentations I have seen there is even sections dealing with Tomcat in various Tomcat books I have seen. True the tuning is dependent somewhat upon the app but even Mark mentioned logging levels, threads that run contineously that might best be tuned off (like checking for new deploys ect). He also mentioned the xmx xms java tuning and what Tomcat without apps (WARs) loaded needs although not sure if he mentioned xss parimeters. I am using the G1 GC by default since that is setup in 1.7.0_05 and the compressed pointers is also setup by default for that version of 1.7.0_05. I am also looking at the OS level to remove uneeded services. I alreadt tuned the network transport parameters as best as possible. FYI I currently am down to the 1-2msec response times as measured at the exposed web services methods inside of Tomcat 7 using 64-bit Oracle 1.7.0_05 JDK and that includes database calls to SQL Server 2012 Express. I have used some of the standard things mentioned by Mark Thomas which has helped alot and looking for more current tips. I am using the latest JAX_WS Metro release and my next step is to go to JAX-RS and look at the size of the request/response and new total response time as recorded in the Apache logs and the client side measurements where currently I am seeing 5-7msec over a 1Gb/s ethernet. Every 6 months or so I do a non-functional tuning exercise that includes code updates like the last one where I eliminated the EJB calls to JBoss and went to jdbc calls from within Tomcat a more bare metal appraoch. That alone reduced my web method round trip time from 6-7msec down to 1-2msec.

Re: Location of Tomcat 7 jvm defualt settings...
Thanks for the quick reply Mark. Yes I saw your comments in one of your presentations about profilier and I am a fan of visualvm and have profiled Tomcat in the past but when down to 1-2msec not sure how much the profilier can pick up. I did notice that as the hotspot engine warms up the response times start to see improvement. I did adjust the -Xss256k from the default of 1M and I am looking forward to when I get home to see the results since the response times quickly went to 3msec after that was set and hope to see 1msec or below after running for 1 day if that change really helps. I did start out profiling the SQL and that helped and switching to the jtds jdbc driver which seem to help even more and of course eliminating the interprocess communication (Tomcat - JBoss). I made sure my data types in SQL server were unicode so the jdbc drive did not do extra conversion work to unicode. I am slowly moving to the front (JAX-WS to JAX-RS) and then a deep dive into OS tuning. After that I will stop tuning for another 6 months I guess.

So I was not able find a real pattern for this issue when I compare the last 3 failures. --- On Fri, 20/7/12, Christopher Schultz ch...@christopherschultz.net wrote: From: Christopher Schultz ch...@christopherschultz.net Subject: Re: java.sql.SQLException: No more data to read from socket To: Tomcat Users List users@tomcat.apache.org Date: Friday, 20 July, 2012, 10:21 PM -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 - -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Vijay, On 7/19/12 8:25 PM, vijay mathew wrote: java.sql.SQLException: No more data to read from socket at oracle.jdbc.driver.SQLStateMapping.newSQLException(SQLStateMapping.java:74) at oracle.jdbc.driver.DatabaseError.newSQLException(DatabaseError.java:110) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:171) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:227) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:439) at oracle.jdbc.driver.T4CMAREngine.unmarshalUB1(T4CMAREngine.java:1042) at oracle.jdbc.driver.T4CMAREngine.unmarshalSB1(T4CMAREngine.java:999) at oracle.jdbc.driver.T4C8Oall.receive(T4C8Oall.java:584) at oracle.jdbc.driver.T4CStatement.doOall8(T4CStatement.java:183) at oracle.jdbc.driver.T4CStatement.executeForDescribe(T4CStatement.java:774) at oracle.jdbc.driver.T4CStatement.executeMaybeDescribe(T4CStatement.java:849) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1186) at oracle.jdbc.driver.OracleStatement.executeQuery(OracleStatement.java:1377) at oracle.jdbc.driver.OracleStatementWrapper.executeQuery(OracleStatementWrapper.java:386) at com.merck.mrl.pcisrr.mrlsos.loginservlet.service(loginservlet.java:124) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) So, when this happens, it always happens alongside an Oracle restart, but an Oracle restart does not always mean you'll get one of these errors? - - -chris - -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEUEARECAAYFAlAJixAACgkQ9CaO5/Lv0PDr8wCY2P8stZkV5AmvW28eYVf2wAYQ SACeJBVjBTrLzWTTtkH1Hcnsh5IPKLI= =pXsE - -END PGP SIGNATURE- -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlAJjJ8ACgkQ9CaO5/Lv0PBKQgCcCQPPTZaSCmug5EBYrXhONKXv PskAn2hQ4zG+gQGK+9t7IyRqWO/0z2AM =ckQ+ -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
