calling native code
Hi, I am using tomcat 4.1.24 and want to use native c-code with JNI. I have a shared library installed in an oracle subdirectory that is added to the LD_LIBRARY_PATH when Apache is started (apachectl) but when I restart tomcat this directory is no longer in it which leads to a java.lang.UnsatisfiedLinkError: error. Where can I modify the LD_LIBRARY_PATH within tomcat ? When I restart Apache, the LD_LIBRARY_PATH is correct but I get a ClassDefNotFound exeception for the class that calls the c-interface (IprShellInterface.class package com.mot.sps.ipr.common). I have installed that class in CATALINA_HOME/common/classes/com/mot/sps/ipr/common/IprShellInterface.class. I called that class successfully before but now I seemed to have run into a deadlock. Can anyone help? Thanks Astrid
Re: calling native code
Hi, I just found out that setting the LD_LIBRARY_PATH var on the shell suffices. When I restart tomcat it takes it from there (working on Solaris 8). Still do not know why I had the ClassDefNotFound exeception after I restarted Apache though. It seems that I always have to go in order 1) Apache and then 2) Tomcat as far as starting is concerned ?!

java.lang.UnsatisfiedLinkError
Hi, I have three different web applications installed and running in three different modes (e.g. test, training ) but basically based on the same code otherwise.

Re: java.lang.UnsatisfiedLinkError
Thanks for the hint.
But I do not quite understand the proposal:
the shared libraries state should be reinitialized.
How do I do that?
Then:
Something which could help is to avoid putting classes which would be
referenced by a shared static field in the web application classloader,
and put them in the shared classloader instead (the JARs should be put in the
lib folder, and classes should be put in the classes folder).
??
Maybe you can tell me what this means in my example.
My webapps use the class IprShellInterface which is in a shared library the following
way:
String shellResponse = IprShellInterface.executeCommand(...);
Here a snippet from IprShellInterface.java:
static {
System.out.println([EMAIL PROTECTED]: The library path is set to: +
System.getProperty(java.library.path));
try {
System.loadLibrary(IprShellInterface);
System.out.println([EMAIL PROTECTED]: Done loading library IprShellInterface);
}
catch (Exception e) {
System.out.println([EMAIL PROTECTED]: Exception loading library IprShellInterface
...
);
System.out.println(e.getMessage());
}
public static String executeCommand(...)
I compile the class into the shared library libIprShellInterface.so and right now
install it in lib of the DB installation (included in the java.library.path variable).
This means that all webapps take the same. If that is the reason for the problem wouldn't it be a solution to
install it into the different webapps lib directories:
./webapps/iprweb-iprdev1/WEB-INF/lib/libIprShellInterface.so
./webapps/iprweb-iprdev2/WEB-INF/lib/libIprShellInterface.so
./webapps/iprweb-iprdev3/WEB-INF/lib/libIprShellInterface.so
and have the java.library.path path be set individually for the webapps. Or is there
only one for all applications?
Where do I set the library path anyway?
Sorry I just have too little info about how this works ...
Thanks

Re: problems starting/stopping tomcat
Hi, I killed some processes related to native c calls I submit and now I can start/stop TC so this time it could have been some non-terminated processes (due to network problem). The question now is: I may have some situations like that e.g due to a network problem a native call can not be finished etc. How do I avoid running into such severe problems: do I have to implement sth. like a timeout in the c programm to guarantee it will quit ?!

how to run web application in different modes like test, production
Hi all, I have a web application that runs -depending on the content of a property file - in different modes. But the application can only run in either one of these modes at a time. I want to be able to run the web application in serveral modes at the same time (e.g to test different DBs, email flows etc). What is the best way to accomplish that ? Thanks for you ideas.

The catalina.out log file simply says: Jul 24, 2003 8:53:58 AM org.apache.commons.modeler.Registry loadRegistry INFO: Loading registry information Jul 24, 2003 8:53:58 AM org.apache.commons.modeler.Registry getRegistry INFO: Creating new Registry instance Jul 24, 2003 8:54:01 AM org.apache.commons.modeler.Registry getServer INFO: Creating MBeanServer Jul 24, 2003 8:54:04 AM org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on port 8080 Starting service Tomcat-Standalone Apache Tomcat/4.1.24 Jul 24, 2003 8:54:31 AM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on port 8080 Jul 24, 2003 8:54:32 AM org.apache.jk.common.ChannelSocket init INFO: JK2: ajp13 listening on /0.0.0.0:8009 Jul 24, 2003 8:54:32 AM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=44/437 config=/home/oraedt/app/oracle/product/9iAS_1.0.2.2/jaka rta-tomcat-4.1.24/conf/jk2.properties [EMAIL PROTECTED](): empty constructor: // this is printout from my code [EMAIL PROTECTED]() start: // this is printout from my code [EMAIL PROTECTED]() before getting system.mode: // this is printout from my code Stopping service Tomcat-Standalone The mod_jk printout says this : [Thu Jul 24 09:01:26 2003] [jk_ajp_common.c (642)]: sending to ajp13 #79 [Thu Jul 24 09:01:27 2003] [jk_ajp_common.c (681)]: ERROR: can't receive the response mes sage from tomcat, network problems or tomcat is down. ... I remember having seen some port 8080 in use problem error message but not in the above test. Apache is configured to run on a different port (7778) and server.xml has: Service name=Tomcat-Standalone !-- Define a non-SSL Coyote HTTP/1.1 Connector on port 8080 -- Connector className=org.apache.coyote.tomcat4.CoyoteConnector port=8080 minProcessors=5 maxProcessors=75 enableLookups=true redirectPort=8443 acceptCount=100 debug=0 connectionTimeout=2 useURIValidationHack=false disableUploadTimeout=true / !-- Note : To disable connection timeouts, set connectionTimeout value to -1 -- !-- Define a Coyote/JK2 AJP 1.3 Connector on port 8009 -- Connector className=org.apache.coyote.tomcat4.CoyoteConnector port=8009 minProcessors=5 maxProcessors=75 enableLookups=true redirectPort=8443 acceptCount=10 debug=0 connectionTimeout=0 useURIValidationHack=false protocolHandlerClassName=org.apache.jk.server.JkCoyoteHandler/ /Service Do I have to use a different connector? Why does the problem occur not right away if it is a port problem? The error comes when I try to read an external java resource bundle (.properties file) even though this may not have sth. to do with the error because the resource bundle is successfully found prior to the error. Thanks for your help. BTW: Is it advisable to use the above configuration since we have an quite old version of Apache? E.g Has anyone experienced mayor problems running relativly new versions of tomcat with an old 1.3 Apache version?? Astrid
Re: tomcat connection/port problem
Yes you are rigth. The resource property was not found in in the resource file that's why it crashed. I simply thought I would get some java error (and not only that tomcat was shut down) that would have made it easier for me to debug. Sorry for the confusion. Astrid Ralph Einfeldt wrote: What makes you so shure that you have a port problem ? I think that you are searching in the wrong direction. As I understand the log message mod_jk complains about not getting an answer from tomcat after it successfully sent a request to tomcat. At this point I cann't imagine a port problem (with that the request would have failed, not the response) This can have several causes: - tomcat is down (e.g. jvm crash) - the thread is not responding at all (deadlock) - the thread is not responding quick enough (it take to long to create the response) - ... -Original Message- From: Astrid Wagner [mailto:[EMAIL PROTECTED] Sent: Thursday, July 24, 2003 9:25 AM To: [EMAIL PROTECTED] Subject: tomcat connection/port problem [Thu Jul 24 09:01:26 2003] [jk_ajp_common.c (642)]: sending to ajp13 #79 [Thu Jul 24 09:01:27 2003] [jk_ajp_common.c (681)]: ERROR: can't receive the response message from tomcat, network problems or tomcat is down. ... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
problem finding css
Hi, I am using Apache 1.3 with tomcat 4.1.24. When I use netscape 7 to run my web application everything works fine. When I use e.g netscape 4 the style sheets can not be found. How do I have to configure Apache/tomcat ? In the html page the source is refered to as: link href=/main.css rel=stylesheet type=text/css Right now I have in http.conf: VirtualHost * DocumentRoot /home/oraedt/app/oracle/product/9iAS_1.0.2.2/jakarta-tomcat-4.1.24/webapps/iprweb ServerName upolu.sps.mot.com JkMount /iprweb/* ajp13 /VirtualHost Alias /html/ /home/minerva/servers/upolu/ipr_files/static_html/ The main.css is installed in /home/minerva/servers/upolu/ipr_files/static_html. Thanks for any hint .. Astrid
Re: problem finding css
No I forgot to state that http.conf has also: DocumentRoot /home/minerva/servers/upolu//ipr_files/static_html otherwise it wouldn't find it in any case. I assume the main.css is looked up in /home/oraedt/app/oracle/product/9iAS_1.0.2.2/jakarta-tomcat-4.1.24/webapps/iprweb because of my: VirtualHost * DocumentRoot /home/oraedt/app/oracle/product/9iAS_1.0.2.2/jakarta-tomcat-4.1.24/webapps/iprweb ServerName upolu.sps.mot.com JkMount /iprweb/* ajp13 /VirtualHost directive. Somehow new netscape versions seem to go to the next DocumentRoot to find a resource when not found in first because as stated before it works with netscape 7. My problem is therefore: How do I tell Apache to take main.css from the global DocumentRoot in http.conf and only the web application from the one in the VirtualHost directive. Static text as well as web should use the same machine/port number. I guess I have to read about the VirtualHost tag more. Thanks anyway.

Re: problem finding css
For my purposes it was wrong to use the VirtualHost directive because my web appl. runs on same host /port. I just left the JkMount directive and it works with old and new netscape version. The mapping to the web appl. doc root is done by workers.properties and server.xml and I thought I have to do this in httpd.conf Thanks.

running as diff. account
Hi, This may be off topic but maybe someone else had this requirement: I need to call a system call running in a different account than the account the web application runs: E.g All web applications etc. run as accountA but my web application needs to call a rsh command (via native interface) run as accountB. Thanks a lot. Astrid - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: running as diff. account
Hi, Can you detail the second solution a little bit: I can create a shell sript with my rsh system command in it and owned by accountB but it will still run as accountA when called by a servlet, won't it. I am no unix expert, maybe you have an example. Thanks Astrid Ralph Einfeldt wrote: There are a couple of solutions that allow you to achive that. Which solution is best, depends on your requirements. Some solutions that require a wrapper script: - script that calls rsh by super or sudo or something like that - script that is owned by accountB and has the setuid bit set and calls the rsh command directly -Original Message- From: Astrid Wagner [mailto:[EMAIL PROTECTED] Sent: Thursday, July 24, 2003 3:44 PM To: [EMAIL PROTECTED] Subject: running as diff. account E.g All web applications etc. run as accountA but my web application needs to call a rsh command (via native interface) run as accountB. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: running as diff. account
John Turner wrote: You're right, file ownership has nothing to do with run privileges. Can you clarify what you need? Is accountB the only account allowed to use rsh? Or are you saying that you want to use rsh to login into a remote host as accountB, but accountA will launch rsh? OK. We allow a certain account accountB to be able to rsh on users machine with the user's account so for example we can check their proper installation etc. Therefore what I want to do is for example have accountB run rsh -l userA userAmachine 'ls /home/userA/someDir' The .rhosts file of the users allow that access. But tomcat as well as all DB related things run as a different account accountA. So how can I get accountB to run the rsh command? I hope I did not confuse you too much ?! Astrid If the latter, then use the -l command-line option to rsh to specify the remote host account name to use, just as you would with ssh.

which mod_jk.so to use with Apache 1.3
Hi, I try to connect tomcat 4.1.24 to an existing Apache 1.3 installation (Solaris 8). To do so I read I need mod_jk.so and I found a download page http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk2/release/v2.0.2/bin/solaris8/ but below it says to get * mod_jk2-1.3-eapi.so is for Apache 1.3.x with mod_ssl * mod_jk2-1.3-noeapi.so is for Apache 1.3.x without mod_ssl and they are not listed above. Has anyone done sth. similar and can tell me what to use if my plans aren't impossible (due to old Apache version) at all? Thanks. Astrid
Re: I'm officially lost with mod_jk
Hi Werner, Sorry to link into your conversation: It seems that you went through the problems I am about to have (connecting tomcat 4 to Apache 1.3: Solaris 8).

deploying with ant
Hi, I am trying to install my web application into a tomcat web installation. I thought ant install is the right thing to do and it successfully performed but I can not see any of my web part within the tomcat installation and neither can I call one of my servlets. I thought I would see my application under the webapps directory but I did not. Do I have to make a ant deploy? The documentation does not say so but how do I get the web application to the tomcat installation? Thanks.

web.xml question
Hi, This is an (hopefully) easy question: I run my new web application but do not seem to get the servlet to run. I can run a simple index.html page (machine:port/my-web-appl/index.html) within my web application installation so $CATALINA_HOME/webapps/my-web-appl/index.html is found.
