Re: Associate .jsp only
Two machines, one running apache, one running jrun. I know I can map directory paths: e.g. /www/htdocs/calendar (on Machine A) /www/calender/jsp/ (on Machine B) So when I call files from http://server.com/calender on machine A, the requests are passed to Machine B. But that would include ANY requests (including images and simple flat .html files) to be served by machine B. I only want files that end with .jsp to be passed from machine A to Machine B. The second issue was me being stupid about loading classes in CF. You can completely ignore it. -= brett At 11:32 PM 1/4/2001 -0500, you wrote: >When you say forward, you want Apache to forward .jsp requests to JRun on a separate machine, right?

Re: [Fwd: servlet debugging]
Ah, now that makes sense! The bean would be reloadable if JRun were a little more developer-friendly, as would modified tag handler classes. But there's a lot of tricky classloader shite necessary to pull of dynamic reloading of all these things: servlets, supporting classes, tag handlers, JSPs, JavaBeans, etc. There are scope issues too, such as whether to dump the whole web-app and reload, or dump just the class at hand and reload, etc. So, JavaBeans called by JSPs are not usually reloadable. I think the current situation is that the JSP gets loaded into its own classloader, but the JavaBean gets loaded into the web-app classloader. So the workaround would be to touch a non-JSP servlet in your web-app and reload that -- which will cause all the servlets and beans in the web-app to be dumped. JSPs are loaded in their own classloader to make it eaiser for RAD with JSPs, I guess. But it should all be working dynamically in a future release (including taghandlers and JavaBeans). To be fair, I think most JSP/servlet engines have these dynamic reload problems in one area or another. Eventually we'll all get it right, I think. -- Scott Stirling West Newton, MA On 04 Jan 2001 11:17:22 -0700, Ben Groeneveld wrote: > Please let me clarify.

Re: Registering EJBeans JNDI name
Are you using JDK 1.3? If not, you need the iioprt.jar file from the
1.3 JDK in your classpath.
At least that's what I'm guessing is the problem. In SP2, soon to be
released, we'll ship iiioprt.jar in JRun's lib/ext dir. This file has
the RMI-IIOP classes in it that are needed for
PortableRemoteObject.narrow().
On the other hand, it may be something else. I'll be glad to help with
it. Take my advice -- stick with the ejb-jar.xml and forget the
properties files. You'll notice that none of the sample clients with
JRun use the PortableRemoteObject method of getting a home object. One
of the samples in SP2 will though.

JRUN 3.0 SP1 bug found
Hello all, I have found a little bug in JRUN 3.0 SP1. I'm running on Windows
NT4.
Specifically, if you create a JSP page with the following content (I know,
it's not very clever to do things this way):
<% out.print("-" + request.getParameter("whatever") == null +
""); %>
It will cause an general protection fault in jikesw.exe when trying to
compile it. (So it's really a Jikes problem not strictly a JRun problem).
It'd be great if someone from Allaire could acknowledge this message (Scott,
hello??)
GPF details attached.

RE: JDBC Drivers +
No. Throwing threads at the Bridge is generally always a bad idea. ODBC
drivers are not guarenteed to be thread-safe to begin with.
Statements/ResultSets are considered "active" from the time they are created
until they are closed; not just when you are making method calls on them.

what
If you want to use more than one statement per connection you have to use a
real JDBC driver. With the ODBC-bridge you can not work seriously with a DB.
You have only one statement per connection and you must use the rs.getXXX
functions for the attributes in the same order as they appear in the query.
At least that is the state with the MS-SQL-Server.
Kind regards

RE: JDBC Drivers +
Not sure why SQLServer is being grumpy and Access works - it's usually the
other way around :)
The only thing that I can think of is that SQLServer is only allowing you
one active statement per connection when working with metadata. Here's what
happens (working from memory here; it's been a long time since I wrote the
Bridge): when you call getTables(), a new statement handle is created, the
ODBC SQLTables function invoked (which causes the underlying ODBC driver to
issue a database query), and the result set is returned. Calling
getColumns() works in a similar way, calling SQLColumns. Maybe SQLServer is
doing some special statement processing/caching when using metadata that
precludes you from having multiple active statements - I just don't know
what the ODBC driver is doing under the covers.
The generic way to program for this case is to build an
array/Vector/Collection of the table names up front, and then process the
column names for each table in a separate loop.
Hope this helps,
Karl.

RE: JRun O/R Mapping
For O/R mapping, Allaire is partnering with Thoughtinc. I haven't tried it myself, but they've put a lot of work into supporting JRun and Ejipt with their CocoBase product: http://www.thoughtinc.com/allaire/index.html There are other O/R tools out there. It would be interesting if someone wanted to work with an open source project (such as jBoss/Jaws http://www.thoughtinc.com/allaire/index.html) to provide a free O/R tool for JRun. There are some other cool tools for EJB dev that would be cool to sup-"port" for JRun, such as Percolator: http://www.percolator.org/source/java/percolator/ (just ignore the alternating spellings of "percolator" on the Web site) And if you haven't seen EJBDoclet yet, it's definitely worth a look; it's free and open source and you can code gen all your EJB interfaces, objects and ejb-jar.xml from a single file using special Javadoc tags: http://sourceforge.net/projects/ejbdoclet/ Scott Stirling Allaire Corporation http://www.allaire.com/developer/jrunreferencedesk/ > -Original Message- > From: Damon Kuntz [mailto:[EMAIL PROTECTED]] > Sent: Thursday, January 04, 2001 9:00 AM > To: JRun-Talk > Subject: JRun O/R Mapping > > > Is there any good documentation available on CMP O/R mapping > in JRun 3.0?

// inner loop
while(columnNames.next())
System.out.println("\t" + columnNames.getString("COLUMN_NAME"));
//MARKER_END
}
Using MDAC 2.5 + sun.jdbc.odbc.JdbcOdbcDriver on Win2000, sun SDK 1.3 works
fine with AccessdataSource
Error with SqlServer
If I put the section between //MARKER & //MARKER_END outside the
tables.next() loop , using a tablename it works fine.
Really a Java issue and not really a JRun issues though :-)
Thanks

Registering EJBeans JNDI name
I'm having trouble understanding, which parts of the EJBean.properties file
registers the JNDI name for that bean. I followed the directions given in
samples.pdf, but they didn't work.
I tried deploying the beans both ways, using the deployment descriptor
ejb-jar.xml and using properties files with manifest file. If anyone has
encountered similar problems and found a solution, I would really appreciate
it if you can let me know.
TIA,
Usha
Below are excerpts of configuration files and my code.
Deploying using ejb-jar.xml:
- Here's how I defined a bean in this file:
XXXHome
com.synapz.eclipz.ejb.XXXHome
com.synapz.eclipz.ejb.XXX
com.synapz.eclipz.ejb.XXXBean
Stateless
Container
ejipt.isCreateSilent
true
- In my client code, I lookup this bean the following way:
void someMethod()
{
System.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"allaire.ejipt.ContextFactory");
System.setProperty(Context.PROVIDER_URL,
"ejipt://localhost:2323");
Context ctx = getInitialContext();
Object home = ctx.lookup("XXXHome");
XXXHome xxxHome =
(XXXHome) javax.rmi.PortableRemoteObject
.narrow(home, XXXHome.class);
}
- I do not have any problem deploying my ejb jar or my client jar. However,
when I run my client code I get the following error:
javax.naming.NameNotFoundException: UserHandlerHome not found
at allaire.ejipt._NamingContext.lookup(_NamingContext.java:73)
at allaire.ejipt._ClientContext.lookup(_ClientContext.java:113)
at javax.naming.InitialContext.lookup(InitialContext.java:350)
.
Deploying using properties and manifest file:
- Here's how my bean.properties file looks:
ejb.beanHomeName=XXXHome
ejb.homeInterfaceClassName=com.synapz.eclipz.ejb.XXXHome
ejb.remoteInterfaceClassName=com.synapz.eclipz.ejb.XXX
ejb.enterpriseBeanClassName=com.synapz.eclipz.ejb.XXXBean
ejb.stateManagementType=stateless_session
ejb.allowedIdentities=all
ejb.runAsMode=system_identity
ejb.sessionTimeout=300
ejipt.env_entries=updateInterval
- the contents of mainifest file are:
Name: com/synapz/eclipz/ejb/UserHandler.properties
Enterprise-Bean: True
- Again I do not have any problem deploying my ejb jar or my client jar.
Now, when I run my client code I get the following error:
javax.naming.NamingException: Failed to unmarshal proxy. Root
exception is java.lang.ClassNotFoundException:
com.synapz.eclipz.ejb.XXXHomeObject_Stub (no security manager: RMI class

JRun O/R Mapping
Is there any good documentation available on CMP O/R mapping in JRun 3.0? I don't find the packaged examples from allaire to be very helpful. Any suggestions would be greatly appreciated.

RE: jrun2.3 NT model
Daniel, it sounds to me as if you are confusing an "outbound" HTTP proxy service with a JRun "connector proxy". These are two very different beasts. The JCP (JRun Connector Proxy) is a JRun service that enables a web server (IIS of Netscape) to talk to JRun, usually via an ISAPI or NSAPI plugin, but possibly via a CGI or even from another servlet... note that the "web server" is actually the connection "client" from a network perspective in this converstation. The web browser is a client of the web server, the web server is, in turn, a client of the JRun service. An HTTP proxy is normally used to allow browsers sitting on a private network to access internet based web sites. A proxy in this configuration is not used to deliver an internal web site to internet based clients. Normally, with such a configuration, internal browsers are "clients" of the proxy server, that, in turn, becomes a client of the externally hosted web site. The fact that you mention a port number like leads me to believe you are attempting to use such an HTTP proxy. An HTTP proxy can not talk directly to a JCP, they do not even speak ths same applicaiton layer protocol. Why are you using an HTTP proxy at all? Why not place a web server on the Internet and use the web server plugin supplied by JRun to access the internal JRun service? This is the "normal" configuration. It is possible to set up an HTTP proxy server as a "reverse proxy" and use it as such to permit external browsers to see an internally hosted web site... but this is probably overkill for your needs. Doing so, you would still need an internal web server to be proxied (not the JRun JCP) Ed. > -Original Message- > From: daniel garcia [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, January 03, 2001 9:31 AM > To: JRun-Talk > Subject: Re: jrun2.3 NT model. > > > Hello. > > Just beginning to learn howto use jrun2.3 while learning java servlets.
