Tomcat 4.1 JSPC not recongnizing change in compile time included file
I am running Tomcat 4.1.24.
In nearly all JSP files in my webapp I have the following compile time
include:
%@ include file=main.jsp%
However, changes to main.jsp are not caught by JSPC. And only the
main_jsp.java source is changed. If I delete all the *_jsp.java files
and recompile all of the JSP files, it works perfectly.
Anyone have any suggestions?
I am using ant 1.5.3 with the following task segment in my build file:
jspc destdir=${jspc.src.jsp.dir}
webinc=${jspc.base.dir}/fragment.xml
package=jsp
compiler=jasper41
classpath
fileset dir=${publish.common.lib.dir}
include name=ant.jar/
include name=jasper-compiler.jar/
include name=jasper-runtime.jar/
include name=servlet.jar/
/fileset
pathelement path=${build.dir}/
/classpath
webapp basedir=${deploy.dir}/
/jspc
I even tried calling JSPC directly using the task fragment described in
the Tomcat 4.1 documentation:
taskdef classname=org.apache.jasper.JspC name=jasper2
classpath id=jspc.classpath
pathelement location=${java.home}/../lib/tools.jar/

RE: Tomcat 4.1 JSPC not recongnizing change in compile time included file
Unfortunately I need to use the static include. (It defines methods and
objects that most of my JSP pages use.)
If Jasper 2 can handle detection of static includes at run-time, why
can't JSPC?
From the Tomcat 4.1 documentation:
(http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html)
Recompile JSP when included page changes - Jasper 2 can now detect when
a page included at compile time from a JSP has changed and then
recompile the parent JSP.

that is expected behavior.
%@ include file=main.jsp%
is a static include, meaning, just copy and paste the file before
compilation.
if you had jsp:include then it should recognize the changes

How do I reload a Servlet from a JSP page?
I am using a JSP page to add and change properties files for my servlet in my development and testing environments. I have Tomcat (4.1.24) set up to reload the servlet on changes to the context (i.e. reloadable=true). When I change an existing properties file, Tomcat responds by reloading the servlet and therefore loading the changes. However, when I add a new properties file (in the WEB-INF/classes directory), Tomcat never reloads the servlet. Even when I change that new properties file Tomcat doesn't reload it until the servlet gets reloaded by some other means. So my question is: How do I reload a servlet from a JSP page? -- Nathan Christiansen Tahitian Noni International http://www.tahitiannoni.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: HttpsURLConnection, Tomcat 4.1.27, and jsse.jar
I assume that you are trying from within your JSP page to connect to another host using HTTPS (i.e. programmatic https client connections). I have had similar problems. How I solved my problems was to use the Jakarta Commons HttpClient. It will handle the programmatic https client connection for you. All you have to do is work with the higher level GET and POST requests with optional parameters. For my purposes (getting a textual response from the remote host) it works extremely well. Of course, you do have to have the remote host's TLS/SSL public key in a keystore file pointed to by: System.setProperty(javax.net.ssl.trustStore, strKeyStoreFilename); You will also need to supply the password to the keystore by: System.setProperty(javax.net.ssl.trustStorePassword, strKsyStorePassword); -- Nathan Christiansen Tahitian Noni International http://www.tahitiannoni.com -Original Message- From: Lukas Bradley [mailto:[EMAIL PROTECTED] Sent: Sunday, October 12, 2003 11:35 PM To: [EMAIL PROTECTED] Subject: HttpsURLConnection, Tomcat 4.1.27, and jsse.jar I'm having a strange problem with Tomcat and javax.net.ssl.HttpsURLConnection. I'm using Tomcat 4.1.27, JDK 1.4.1_04, and the jsse.jar containing the javax.net.ssl and other fine classes. I've read about certain bugs located here http://java.sun.com/j2se/1.4.2/docs/guide/security/jsse/JSSERefGuide.html#InstallProbs under the heading Code Using HttpsURLConnection Class Throws ClassCastException in JSSE 1.0.x. That is exactly the problem I am having. However, my command line tests work fine. The JDK works fine by itself. There is no ClassCastException. That means that the regular command-line version of the HttpsURLConnection is wonderful. The JSSE classes are configured correctly using java. However, if you attempt to hit the jsp located at http://www.dollars.com/URLTest.jsp, you'll get an error message with the aforementioned ClassCastException. Tomcat and/or Catalina are not finding the classes, or are having a rough go with the configuration. Since the JSSE classes now ship with JDK 1.4, I've been having a hard time understanding why we are getting this error. The only two ideas I have are (1) Tomcat is running off an old JDK (which I don't think is the case) or (2) there is some configuration error. Attempting to place the System.setProperty() kludge-fix in the JSP, it still doesn't work. Does anyone have any insight as to how the Tomcat/Catalina settings could have the JSSE classes misconfigured? Also read this: http://jce.iaik.tugraz.at/mailarchive/iaik-jce/msg02392.html And this: http://forum.java.sun.com/thread.jsp?forum=2thread=254821 But, as you will see in the JSP, it doesn't help. I've also tried javax.net.ssl in the package property, and it doesn't work. Do any and all searches for jsse tomcat ClassCastException and you'll see stuff. I think you might have to explicitly install the JSSE classes into the java \lib\ext directory, which still doesn't make sense, because they should be included in 1.4.1 anyway.

Tomcat 4/5 Clustering.
Filip, Thanks for the link to your site on Tomcat clusters. Are there any preliminary results about cluster size vs. replication traffic and limitations? If I remember right, the limit for load balancing clusters using an older method was about 6 servers in your cluster before the session object replication became the bottleneck. It was this reason alone that I stopped using the session object to store session info. I store my persistent objects to a MySQL database, using a session cookie as the key to the database row. Are there plans to support Session Object storage in a database (like my method of storing persistent objects)? This would allow massive scalability in the cluster, since the 'dirty' session object only needs to be sent to one place instead of to all the Tomcat servers in the cluster. I realize that this introduces a problem in that every single server in the cluster needs to be running the same version of Tomcat in order to have session objects serialize and deserialize properly. Or that you will need to use another storage format other than simple serialization and deserialization. -- Nathan Christiansen Tahitian Noni International http://www.tahitiannoni.com -Original Message- From: Filip Hanik [mailto:[EMAIL PROTECTED] Sent: Friday, October 10, 2003 10:20 AM To: Tomcat Users List Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Clustering Tomcat - Loadbalancing and Failover http://cvs.apache.org/~fhanik/ how are session states replicated? once, after the entire request is completed.

RE: Tomcat 4/5 Clustering.
It has been done for years, PersistentManager does that already. It is a pretty slow way of replication Thanks, I'll look at PersistentManager. Slow? I guess so. I have eliminated most of the database overhead by using DBCP to create a connection pool. However... Using my method of persistence, on my development PIII 500Mhz 256MB RAM RH Linux 7.1 box under a JMeter simulated 25 user load, I only got 340 pages per minute on some simple JSP pages and 100 ppm on the most computationally intensive JSP page.

RE: include statement in servlets
While this is true there are also ways to accomplish similar results: - calling the service method of another servlet directly.

RE: Urgent help, please!Best practices using Connection Pool
DBCP wraps the connection object. When you call conn.close(); on the connection object given to you by the DataSource.getConnection(); method, it just releases it back into the pool, it dosen't actually close the connection. -- Nathan Christiansen Tahitian Noni International http://www.tahitiannoni.com -Original Message- From: Jose Euclides da Silva Junior - DATAPREVRJ [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 08, 2003 5:19 PM To: '[EMAIL PROTECTED]' Subject: Urgent help, please!Best practices using Connection Pool Hi, i am using DBCP 1.0. My question is simple: since DBCP doesnt create a singleton object ( just a data source object), what should i do whenever my sql queries are done? Should i close the connection after that? But, if i do this, will i loose my connection pool facility, so my next connection time will waste more time...

MySQL DBCP pool exausted error message
When I stress test my web app using JMeter, I am suddenly getting a DBCP could not
obtain an idle db connection, pool exhausted SQLException thrown.
When I test with 25 simulated users every one of my 25 threads gets the exception
after the first 25 requests.
What am I doing wrong?
My setup:
RH Linux 7.1
Java 1.4.1_01
Tomcat 4.1.24
DBCP 1.0
MySQL 3.23.56
My pertinent DBCP configuration:
removeAbandoned = true
maxActive = 25
maxIdle = 10
maxWait = 1
url ends with ?autoReconnect=true
I double checked that all of my database connections in my code follow the pattern of:
Connection conDBConnection = getConnection();
PreparedStatement psDBStatement = null;
ResultSet rsDBResult = null;
try
{
psDBStatement = conDBConnection.prepareStatement(select query from views where
viewid = ?);
psDBStatement.setInt(1, nViewID);
rsDBResult = psDBStatement.executeQuery();
if (rsDBResult.next())
{
strReturnValue = rsDBResult.getString(1);
}
}
catch (SQLException sqle)
{
sqle.printStackTrace();
strReturnValue = null;
}
finally
{
try
{
if (rsDBResult != null) rsDBResult.close();
if (psDBStatement != null) psDBStatement.close();
if (conDBConnection != null) conDBConnection.close();
}
catch (SQLException sqle)
{
sqle.printStackTrace();
}
}

RE: MySQL DBCP pool exausted error message [SOLVED]
Sorry. I had a bug in my code.
I had one database call where I was checking parameters and returning without calling
Connection.close();

Simplified Chinese to UTF-8
I have an annoying problem that I am trying to figure out.
I need to support Simplified Chinese in a webapp that also supports ISO-8859-1.
I figure the best way is to make my web pages encoded in UTF-8.
The database access and display works, but I am having trouble with getting post data
to come out correctly.
I am running Tomcat 4.1.24 on a RedHat Linux 7.1 box with JDK 1.4.1_01.
I have tried using the following JSP file to test the post input from a Windows 2000
Server box that allows me to input Simplified Chinese. But every encoding in the JSP
file gives me garbage back.
Any ideas?
Thanks.

RE: Simplified Chinese to UTF-8
Thanks Dan. I did download the filter code and tried all of the Simplified Chinese encodings without luck. I am unsure which encoding that the IME is sending (since I do not read Chinese myself and can't read the help manual). Looking through the filter code, it would be exactly similar if I added the request.setCharacterEncoding() call to the top of the JSP page since I am calling the JSP page directly.

Problem with custom TrustManager for SSL in Tomcat 4.1.24
I have coded a custom TrustManger and HostnameVerifier for SSL (actually TLS)
connections from my servlet code to another server.
The code calls the correct methods to setup the Default TrustManager and
HostNameVerifier for an HttpsUrlConnection.
I then use the URL.openConnection() method to instansiate the connection.
Running standalone, this code works perfectly, however running under Tomcat on the
same machine the HttpConnection does not use the custom TustManager that I coded.
Any suggestions?
Code to set up default Trust Manager, etc.:
private static void initSSL()
{
try
{
TrustManager[] myTM = new TrustManager [] { new ProxyTrustManager() };
SSLContext ctx = SSLContext.getInstance(TLS);
ctx.init(null, myTM, null);
SSLSocketFactory sslFactory = ctx.getSocketFactory();
HttpsURLConnection.setDefaultSSLSocketFactory(sslFactory);
HttpsURLConnection.setDefaultHostnameVerifier(new ProxyHostNameVerifier());
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
