Re: [JBoss-user] Obtaining a transaction from outside JBoss in another VM Plan
Surprise...in the J2EE-1.3 PFD spec, section 4.2.5, it is stated that the J2EE Product Provider is not required to support transaction management for application clients. However, transaction management needs to be provided for web components. This is strange, if a web componnent (a JSP or a servlet) runs in a separate VM, the web component would look pretty much like an application client, so one would think that if web components are supported, then application clients should be supported as well...the spec does not seem self-consistent.

Re: [JBoss-user] Benchmark????
This is very dependent on the architecture of your application. There are a lot of variables that can effect the ability of any application server to scale. You really should do some prototyping of the architecture you intend to build so that you know how _your_ design decisions effect performance. -danch Emerson wrote: > I´m going to propose using JBoss in our app. Anyone has a kind of > benchmark.

Re: [JBoss-user] :-( Interbase transaction problems
Hi, I looked at the ic2 code and think there may be a problem with setting blobs on prepared statement input parameters, however all my tests so far work fine. If you can identify the statements used I would like to see them, perhaps we can find out if there is an interclient bug. (I think this may be an interclient bug because interclient is a jdbc 1 driver, everything is always in a transaction) There is a debug flag for jaws, but I do not remember how to set it. You can probably find it in documentation or by searching the archives. david jencks On 2001.06.17 12:07:44 -0400 Lewis Henderson wrote: > Hi all, > > I have an application working well under MSSQL7 but ported to InterBase 5 > I > get the following... > > I am calling an EJB method on a Stateful Session Bean with Tx Attr = > 'Required'.

[JBoss-user] Tips for newbie: getting start with tomcat example in [jBoss+tomcat]
Hi, The following show you how to run the examples that come with tomcat under [jBoss+tomcat]. It probably has been answered somewhere, but I try to make it as simple as possible. enjoy! How to run example that comes with tomcat using [jBoss + tomcat] = Assume that is your installation home. 1. make sure that your jBoss starts without any question. - Start it using run_with_tomcat.bat under \jboss-2.0-FINAL\bin\ You should see the following line appears on your screen : [Default] jBoss 2.0 FINAL Started 2. Copy .war file. - Go to \tomcat-3.2-b7\webapps directory You should find a file called examples.war. Copy this file to the deploy directory which is \jboss-2.0-FINAL\deploy on my machine. After done copying, you should see some output in the window console. 3. Testing. --- Now, those examples are deployed under the environment and you can use the following line to go to the menu page of those examples. http://localhost:8080/examples/jsp/index.html 4. Question. (1) If you see the following excepiton been thrown, : javax.servlet.ServletException: sun/tools/javac/Main at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:508) : Fix: add /lib/tools.jar to your classpath and restart everything. (2) If you are curious where are those generated java source file for jsp file, they are in the following directory: \tomcat-3.2-b7\work\localhost_8080%2Fexamples Cheers, FengShuo ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

Please modify properties files in \conf\default when ur running JBoss WITHOUT tomcat (click run.bat) and modify the properties files in \conf\tomcat when running JBoss WITH tomcat (click run_with_tomcat.bat). I did not realize this and spent quite some time figuring this out. Please make a note of this and hopefully this saves some time for some of u ppl out there.

[JBoss-user] :-( Interbase transaction problems
Hi all, I have an application working well under MSSQL7 but ported to InterBase 5 I get the following... I am calling an EJB method on a Stateful Session Bean with Tx Attr = 'Required'.

RE: [JBoss-user] xalan 'n' stuff
Victory So the mystery unfolds I indeed had jaxp.jar in jboss' classpath, so I removed it. I also added xalan.jar in the startup .bat file (run_with_tomcat.bat) and now it works! Thank you all, thank you... world is a nice place to be again!:) ..weird that jboss didn't found it from jboss/lib/ext ..what might be the reason? If crimson.jar is loaded first, could this somehow cause xalan.jar to be ignored.

Re: [JBoss-user] very very new bee
Hi Jean,
if you downloaded the jboss-tomcat package you don't have to worry about
all these variables, simply unpack into a folder (doesn't matter what
name that folder has) and run the run_with_tomcat.bat/sh script in the
bin folder of jboss
make sure that 'java -version' run from the command line prints out the
correct java version needed to run jboss (I recommend JDK1.3, do not use
JDK1.4 beta, as it caused several crashes when running jboss)
if you have more than one JDK/JRE installed on your system, you either
should set up your PATH variable including the {JDK_PATH/JRE_PATH}/bin
directory you want to work with or set up JAVA_HOME pointing to
{JDK_PATH/JRE_PATH} and modify run.bat/sh in the jboss/bin directory so
that the last line starts with:
$JAVA_HOME/bin/java (for UNIX/LINUX) or
%JAVA_HOME%\bin\java ... (for WINDOWS)
another way is to link the 'java' command directly to your JDK:
if you installed the JDK1.3 under c:\jdk1.3 then modify the run.bat and
write
c:\jdk1.3\bin\java ...
if run_with_tomcat.bat/sh starts you should see a lot of output on your
screen, ending with something like
"[Default] JBoss 2.2.2 Started in 0m:11s"
if you get to see this your JBOSS server is running
open your browser and point it to 'http://localhost:8080/jboss'.
if you don't see the jboss test page something went wrong and you should
browse through the output JBOSS has generated on your screen for error
messages.
hope this will work for you.
p.s.: to set up environement variables under windows simply use the
windows-help and look for environement, it will give you all the
information you need, under linux/unix there are several ways how to set
up those variables and you should buy a book on this issue or ask a
friend who knows more about this...

RE: [JBoss-user] :-) EJB2.0 RunAs
Scott, Why do you have anything to add to the jboss-web.xml? Surely the only entry that needs adding is the element in the tag in the web.xml to provide this feature. The current entries (web.xml and jboss-web.xml) allow you to set up security...so the only thing missing is the element to supply a for 'unauthorised' access, and to also override the current Principal if there is an authenticated user. (Am I missing something?) This, in fact, solves my WAR-EJB security issues. I provide internal roles for my hidden EJB's and map to them in the WAR file's entries. My WAR users are not members of these roles. My other problem...(Scheduler)...is now solved...I did as you said and set it up as a regular client and hey-presto! ...and aside...The principal/credentials supplied in the environment during a JNDI lookup seem to be ignored...Is there a use for them or does JAAS replace them? Regards Lewis -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Scott M Stark Sent: 15 June 2001 16:18 To: [EMAIL PROTECTED] Subject: Re: [JBoss-user] :-) EJB2.0 RunAs What I implemented is the EJB2.0 run-as feature.

This case is an unauthenticated client accessinga servlet that in turn accesses an EJB. The servlet 2.3 run-as feature will allow you to specify a role to use for security purposes. The J2EE 1.3 spec also mentions supporting this in different ways. See below. > I also need to have a 'loaded-on-startup' servlet (A scheduler in a WAR) to > access EJB's without a 'real' user logging on. However if a 'real' user does > access the servlet, they need authenticating in the normal manner. This is not handled by the servlet 2.3 run-as. You cannot conditionally fix the identity based on whether the caller to the servlet is authenticated. You would have to deploy an unsecured version that has the fixed run-as identity and a secured version that passes the caller identity. If your talking about accessing the EJB from a thread created by the servlet, then you have to set the security identity yourself as though your were a Java client. The only docs for run-as are the servlet 2.3 spec. These are the two places it is mentions in the 2.3pfd2 spec: SRV.12.7 Propagation of Security Identity in EJB Calls. A security identity, or principal, must always be provided for use in a call to an enterprise bean. The default mode in calls to enterprise beans from web applications is for the security identity of a web user to be propagated to the EJB container. In other scenarios, web containers are required to allow web users that are not known to the web container or to the EJB container to make calls: . Web containers are required to support access to web resources by clients that have not authenticated themselves to the container. This is the common mode of access to web resources on the Internet. . Application code may be the sole processor of signon and customization of data based on caller identity. In these scenarios, a web application deployment descriptor may specify a run-as element. When it is specified, the container must propagate the security identity of the caller to the EJB layer in terms of the security role name defined in the run-as element. The security role name must one of the security role names defined for the web application. For web containers running as part of a the J2EE platform, the use of run-as elements is supported both for calls to EJBs within the same J2EE application, and for calls to EJBs deployed in other J2EE applications. Now, the J2EE 1.3pfd3 spec talks about providing support for unauthenticated users. I am going to add support at the war level for specifying the unauthenticated user run-as role using a jboss-web.xml application level element. J2EE.3.4.3 Unauthenticated Users Web containers are required to support access to web resources by clients that have not authenticated themselves to the container. This is the common mode of access to web resources on the Internet. A web container reports that no user has been authenticated by returning null from the HttpServletRequest method getUserPrincipal. This is different than the corresponding result for EJB containers. The EJB specification requires that the EJBContext method getCallerPrincipal always return a valid Principal object. The method can never return null. Components running in a web container must be able to call enterprise beans even when no user has been authenticated in the web container. When a call is made in such a case from a component in a web container to an enterprise bean, a J2EE product must provide a principal for use in the call. A J2EE product may provide a principal for use by unauthenticated callers using many approaches, including, but not limited to: . Always use a single distinguis
