java startup option trouble
Hello List... I have a requirement to startup java with a -noverify option. I've put this is /etc/profile as a JAVA_OPTS value. My probem is on system startup, Tomcat starts ok but the classes that need the -noverify parameter don't work until I login as root, shutdown Tomcat then start it up again. It seems that the profile is not read until I've logged in (as root). If that's the case, how can I set it up so the -noverify parameter is the default when java loads? Tomcat 4.1.27 on Redhat 8.0 Thanks for any assistance. /j-p.
alias directive/Virtual host problem
Hello List... In order that a virtual host respond correctly to urls: http://mydomain.com http://www.mydomain.com I've had to add two host entries in server.xml (one for mydomain.com, the other for www.mydomain.com). I thought it would have been enough to add the alias directive for the www.mydomain.com in the mydomain.com host, thereby avoiding duplication within server.xml? Are there problems with the alias directive - or am I misinterpreting it's function? Is it just that my configuration is probably bad?

[OT]Re: Mobile phone on serial port - Howto send sms?
Hello List... Apologies for the cut and paste of the thread below... I just wanted to add an answer to the problem I had of how to send an sms using a servlet. I'm sure that the ability to send GSM text messages would be very useful - at least for the Euro-tomcatters. The following URL provides a small .jar to do exactly that: http://www.waex.com/techinfo/sms.htm (Many thanks to Philippe Bertramo for the code) /j-p. List: tomcat-user Subject: Re: Mobile phone on serial port - Howto send sms? From: Christopher Williams ccwilliams3 () ntlworld ! com Date: 2003-09-11 8:36:27 Seems a bit cheeky: the question how do I send SMS messages using Tomcat? is really how do I send SMS messages using Java? and there are probably more relevant mailing lists for that question. Anyway, presumably your mobile phone can impersonate a Hayes modem, so you need to open up your COM port and write Hayes commands to dial the number you want. Then you need to write your SMS message. This is a standard, so you need to obtain the appropriate standards documents. Then you hangup the phone, again using Hayes commands. An alternative is to use a web-based SMS service, such as the one on Lycos, and then post the appropriate data to the URL. There are commercial services available as well - do a Google search. List: tomcat-user Subject: [OT]Re: Mobile phone on serial port - Howto send sms? From: Kwok Peng Tuck pengtuck () makmal ! net Date: 2003-09-11 5:12:38 Another option is available to you John-Paul, specifically, http://www.kannel.org which is a wap and sms gateway. This gateway is based on linux although you can use cygwin to compile and run it, far from ideal but it does work and is usable enough for testing. The gateway does support most GSM modems and supports other major protocols like SMPP, CIMD... for connecting to telcos. Once you set it up you can send sms through it's http interface. So from your servlet or business logic class, just make a http call to the gateway with the correct parameters and your sms will be sent of. A library like commons http-client will be quite useful in this case. FYI : kannel is open source.

I read the 1.4 JavaDoc and I'm still not convinced either way. Just in case it doesn't read the stream until later, simply use another stream: URL urlImage2 = getServletContext().getResource(second image); URLConnection urlImageConn2 = urlImage2.openConnection(); int urlImageLength2 = urlImageConn.getContentLength(); InputStream is2 = urlImage2.openStream(); pStmt.setBinaryStream(x, is2, urlImageLength2); Don't forget to close your streams and URLConnections when you're done (i.e. in a finally block)! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
OT: db pool problems - jdbc connection count?
Hello List... Sorry if this is off-topic. Although I think I'm following the jndi-resources-howto fairly well, I find I'm running out of connections and I have to restart tomcat to free them up. I'd like to know how many jdbc connections are in use at any given time with the intention of finding the offending servlet(s). I'm using postgreSQL. I've googled and looked at the postgres user lists but not found an example on how to detect the current number of connections in use. Can anyone help? tomcat 4.1.24 postgresql 7.3.3 pg73jdbc3.jar commons-pool 1.0.1 I believe I'be been pretty thorough in closing down resultsets, preparedstatements and connections after use, and use the removeAbandoned parameter in the DataSource Resource section of server.xml.

Re: OT: db pool problems - jdbc connection count?
Thanks Oscar... I ran some servlets and observed the postgres processes going over the maxActive (33 to 30) limit set in server.xml and also those processes marked idle topped the maxIdle value (21 to 15). The number of processes then dropped to 25, and I don't experience any problems with db connection resources. It appears some reclaiming of connections did take place. I'm as much in the dark as ever regarding the cause of connection resource maxing out however.

JNDI DataSource - need to synchronize?
Hello List...
Some coding help please. Following earlier advice on this list and the TC datasource
how-to, I've now got a working test servlet. Basically I declare the Context(s) and
DataSource as instance variables, and initialize them in init:
Context initContext = null;
Context envContext = null;
DataSource ds = null;
public void init() throws ServletException {
try {
initContext = new InitialContext();
envContext = (Context) initContext.lookup(
java:comp/env);
ds = (DataSource) envContext.lookup(
jdbc/jpdb);
} catch (NamingException e) {
throw new ServletException(
Couldn't setup JNDI Context/DataSource, e);
}
}
==
If this is the correct approach, should I be synchronizing the Context(s)/DataSource
in the doGet method? If another http request thread closes it's own connection, will
it affect the Context or DataSource object of this request?
Thanks for any clarification,
/j-p.

[OT] JDBC confusion
Hello List... newbie question coming up: If I set up a jdbc connection object in one servlet, do I have to close it each time or can the same connection be re-utilized by other servlets each using a different sql statement (perhaps storing the connection as a session attribute?). Is there a significant resource saving by not creating a JDBC connection object for each database access? I'm thinking of storing a connection for each user in the session, as opposed to pooling - primarily because I'm not sure how a database pool works nor how to set it up.

Re: Html/jpg from db to client?
Are there any examples of these techniques available? thanks /j-p. On Mon, 22 Apr 2002, Jeffrey Bonevich wrote: Nope. Only need two at most. Each of them sets their own content type (image streamer sets it to image/jpg, HTML producer to text/html). And in answer to your other question, yes, this could be reduced to just one servlet that does conditional setting of content-type and content. But you will then need a querystring (or other) key/value pair to do the conditional on. Suppose your HTML page url is /servlets/showimage/1. Suppose the 1 in the subpath is the id for the image. Then you need to have a switch in the URL to tell it whether you are getting html or image: /servlets/showimage/1?show=1 SO now your HTML page is accessed with the URL /servlets/showimage/1 and inside that page is embedded an img src=/servlets/showimage/1?show=1 height= + image height + width= + image width + Then in your showimage servlet, you grab the show request parameter and, if it is present/equals 1, then set content type to image and stream the image, otherwise set content type to html and output HTML (or forward to JSP - just be sure to stick the image info somewhere in a context so you can access it in the JSP page).

Re: I'm stuck. Apache-tom4.0 virtual hosts
I'm a newbie with this but here's what I got... The jakarta documentation says the Host element represents a Virtual Host. One or more Host elements are nested inside an Engine element. ..and on an Engine element it says, Exactly one Engine element must be nested inside a Service element, following all of the corresponding Connector elements associated with a Service. ..and on a Connector it says, HTTP/1.1 and Warp are typical connectors. So in the server.xml file, I used the Tomcat-Apache Service, and placed some Warp Connectors (making sure they utilized unique ports), one for each one of my virtual hosts within the service as follows: !-- Define an Apache-Connector Service -- Service name=Tomcat-Apache Connector className=org.apache.catalina.connector.warp.WarpConnector port=8008 minProcessors=5 maxProcessors=75 enableLookups=false acceptCount=10 debug=0/ Connector className=org.apache.catalina.connector.warp.WarpConnector port=8015 minProcessors=5 maxProcessors=75 enableLookups=false acceptCount=10 debug=0/ !-- Replace localhost with what your Apache ServerName is set to -- Engine className=org.apache.catalina.connector.warp.WarpEngine name=www.myServer.com debug=99 appBase=webapps Then I added in my Hosts (Default Host as in server.xml and others for each virtual host). It was only when I used this configuration that the entries in httpd.conf were accepted and responded ok. Example from httpd.conf follows: VirtualHost 192.168.1.2 ServerAdmin ...

Nevertheless beware... this outcome is more the result of trial error than a logical understanding of the components on my part. HTH /j-p.

I have the module loading fine. But I haven't found how to configure httpd.conf for tomcat as well as the server.xml file. Anyone get this working properly? I on red hat. But I would think the config should be similar on other os's..

Using Warp Connector only: remove http from server.xml?
Hello List... Newbie question. Setting up Redhat7.0/TC4.0.1/Apache1.3.20 and after some ironing out, all now appears to work as expected. My question is: do I still need the standalone http connector (configured in server.xml) when I'm using Warp with Apache? thanks /j-p. - JUSTATEST Art Online. www.justatest.com -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
