Displaying image files stored in a database
Hi, I'm developing an web-based Employee Directory for my company. I've got it working all right. My problem is that I'd like to store the image files in a database (presently I'm using Hypersonic) and be able to display them as needed for each employee. However, I haven't been able to that. I worked aroud this problem by storing the images in the file system and entering a path to the required image file as a VARCHAR in the database. Eventhough it solved my problem, it is undesireable because I'd have to manually delete each image file that's no longer required instead of simply deleting a row in the database. I successfully stored each file as a Java object (in this case "File") but I just couldn't think of a way to display it on a web page. I'm sure this is a piece of cake for most of you out there but I just can't figure it out. Any he.lp would do. Thanks.

Orion and SSL
Hi, I've already browsed the list archive and I've seen that many people have had this problem but I didn't find a solution. So my problem is the typical "Error listening to SSLServerSocket: No available certificate corresponds to the SSL cipher suites which are enabled" I already imported the certificate using "keytool -import -trustcacerts -file mycert.der -keystore keystore", the certificate has been granted to the same hostname which is specified in the mysite-web-site.xml file, the certificate is valid until october, created by Verisign, 1024 public-key..., SSLv1, it works fine with Apache. So, is there any log file where I can get a more specific error message? Have I forgotten to do something? Any hints?

RE: Displaying image files stored in a database
Hi, I guess you could write the URL to all images from the database as '/databaseimage/primary key'. For example: '/databaseimage/13'. Then you map a servlet to /databaseimage. This servlet cheks the request URI for the primary key, reads the file from the database and then sends it on the response.

Problems with servlet mapping
Okay, I have a web app that maps "/" to servlet X. According to the Servlet spec, this is supposed to make X the default servlet. Also, according to the spec, the container is supposed to do a recursive search for the longest matching path. Here's the problem, when requests come in for things like: /images/img.gif, the container is mapping those to X as well. Ouch! Basically, "/" is being interpreted to mean "/*". The strange thing is that, while playing around with it, I redeployed once and, all of a sudden, it worked correctly. Then, when I redeployed later (changing something totally unrelated and not web.xml), it went back to the incorrect behavior. Has anyone else encountered this behavior? Is this a bug? I'm using 1.4.5. Help would be greatly appreciated, Dan Cramer Chief Architect Dynamic Resolve, LLC Internet Solutions Consulting

Unicode and Orion in Java-Client

The data in unicode-format are stored correctly in the database, I just tested it with a java client connecting directly to the database. But I get garbled data when using a simple client connecting to orion. I think it is just a flag which has to been set to tell orion to work with unicode but I don't know which.

Using Session Variables
Hi.
I'm having some
difficulty using session variables. Here's a short abridgement of my code in
evaluate.jsp:
HttpSession thisSession =
request.getSession(true);
...
while(enum.hasMoreElements()){
intValue = fncFunction(...);
switch(value){
case -1:
thisSession.putValue("errorMsg","Error in
fncFunction()");
response.sendRedirect(response.encodeRedirectURL("../errorpages/error.jsp"));
break;
case -2:
...
}
}
The problem: the
error.jsp page sometimes shows some of the HTML code in the evaluate.jsp
page.
The error.jsp
pagelooks something like this:
HttpSession
thisSession = request.getSession(true);
String
strError=(String)thisSession.getValue("errorMsg");if (strError!=null
strError!="")
out.println(strError);else out.println("Ingen
nærmere feilbeskjed er tilgjengelig.br");
What's the problem
here?? It seems to me that the session variable includes much more than my
simple errorMsg.

RE: Any news from Orion yet??
Weblogic (and the high priced products like Websphere) are great, if you want to pay the price. They come with nice tools like front end gui's, good documentation, paid support, etc. But if you look for the opinions of developers who have used these products, and compared them to Orion, jboss, etc., they would say the EJB capacies are no better then the other high priced products. In order of ranking, here's how I look at the other products. 1 Orion -- This product is ready now, but I haven't seen anyone from this list run a Sears store on it. 2. Jboss (www.jboss.org) -- The founders are very bright, have five hundred developers on the projects, have EJB heavies contributing to the list, and it's a very easy to use product. Personally, even though it is ready for production now, I would wait for it to mature a bit more. It's like a fine wine -- drink it now, and it is OK, or allow it to age a bit then drink it (like jboss 3.0 final). 3. Openejb (www.openejb.org) - this project has a very bright and well known person heading it, and it is slated to be intergrated with Tomcat and Apache. It has yet to prove itself, as it is not yet ready for production release. But it has good future promise. 4. Jonas (www.evidian.com/jonas) - This is a good product, but it is not as advanced as the other two open source products and I don't think they have as many people behind them. 5. Enhydra enterprise (www.enhydra.org). If you like the enhydra application server, this product has potential. But it is not production ready yet and it intergrates with the jonas server. In summary, Orion is here now but can it run Sears? Jboss is ready but I would let it mature a bit more for production environments. Openejb and Enhydra have great potential, but they are not ready yet and have to prove themselves. Jonas is OK but I prefer the other open source alternatives. -Original Message- From: Anthony W.

RE: Using Session Variables
If this is in a JSP page, you don't need to get the session from the
request. Go to the java.sun.com site, select APIs, select Java Server Pages
and print yourself out the JSP Syntax Card. It tells you what you can use in
JSP. There is a session variable already defined for you. Also, there is a
servlet context variable (application scope), and others as well.
As for why one page is getting some HTML from the previous..it has nothing
to do with your session use. That is just a Hashtable of objects stored by a
key name. I don't remember for sure, but it has something to do with the way
pages are being flushed. If you forward from one page to the next, you
continue to build upon the html that goes back to the client. When you
response.sendRedirect(), my guess is that the buffer is not completely
flushed or something. I believe the JSP Syntax Card has an item that you can
set at the top of a JSP page that flushes the buffer. Look for that and see
if that helps. May I also suggest you use a simple MVC framework? If your
using Servlet 2.1 I have made one that makes it very easy to develop with.
Struts is another very good MVC framework more complete than my own.
Let me know if you are interested in that approach, which will resolve this
for you but require a bit different approach in coding (one that thus far
most people believe is a better more manageable and more scalable approach
than calling JSPs from other JSPs).

Re: Displaying image files stored in a database
Hi, I have recently done what you are looking for using (not surprisingly if you take a look at my e-mail) an Informix database. I stored the images as blobs in the database and used a singleton class (called through a JSP custom tag) to retrieve the images to the file system and manage a cache which can be easily configured (size of the cache area and time before an image expires). Informix provides a function called blobtofile which makes if very easy to transfer the file from the database to the filesystem. This allows me to bypass the jdbc calls which are slower. You should however be able to do something similar with a java database like InstantDB (I am not sure about Hypersonic, since I have never used it). By storing the image inside a database you make sure that you maintain the data integrity and the cache allows you to get file system like performance. The result is a clean readable code in the JSP page. Here is an example: ip:DownloadFromDB table="vs_images" column="image" indexColumn="content_id" index="%=document.getId()%" indexColumn2="order" index2="1" fromCache="false" ip:Success name="file" type="InstantPortal.ImageFile" IMG SRC="%=file.getImageURL()%" /ip:Success ip:NoResults Empty /ip:NoResults /ip:DownloadFromDB Regards, Huibert [EMAIL PROTECTED] wrote: Hi: How about creating an object that first deletes the image file referenced in the database then deletes the record itself?

RE: Problems with a finder method in a cmp
Suppose you had a widget CMP entity bean, with a handedness field, and
wanted to get all the left handed widgets. You'd use a finder method,
findByHandedness("left"), to return a collection of left handed widgets.
Orion makes this easy; just define it and go. See
http://www.orionsupport.com/ for details (
http://www.orionsupport.com/articles/ejbfinderquery.html ). More
complicated finders ("left handed widgets sold on Mondays") takes a little
more effort, also described on Orionsupport.
BTW, Orionsupport is a private effort, not an official site. The
maintainer occasionally uses the server hardware for other purposes, so if
it doesn't respond wait a while and try again later.

We are not using servlets, but a Swing Applet client contacting the beans directly and I'm getting the following exception: javax.xml.parsers.FactoryConfigurationError: com.sun.xml.parser.DocumentBuilderFactoryImpl at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:80) at com.evermind.xml.e.getJavaxDocument(JAX) at com.evermind.xml.XMLUtils.getDocument(JAX) at com.evermind.xml.XMLConfig.ay(JAX) at com.evermind.server.ApplicationClientInitialContextFactory.getInitialContext(JAX) at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:668) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:246) Exactly what jars need to be on the client side?

RE: JNDI Lookup from Applet
Hi, The simpel answer is everything. You need the include orion.jar and all it friends. I know this is a pain in the neck as it adds around 3mb to the application and hurts us a lot her. (Thats the one of the reasons why I am sitting her at the moment porting xml files to be valis so the works with sybase EAS 3.6.1. (Orion doesnt validate the ejb-jar.xml's properly so it was a huch task correcting them to spec. (with more that 1200 session and entitybeans its a pain.)))

RE: JNDI Lookup from Applet
Hi,
Commenting on myself. I forgot to add the client side code Just
remeber you can only make a context once from a client. Then you must reuse
that one to get the ejb-instances.
Her it is initialisation:
java.util.Hashtable env = new java.util.Hashtable();
env.put(javax.naming.Context.APPLET, this);
env.put(javax.naming.Context.SECURITY_PRINCIPAL,
getParameter("java.naming.security.principal"));
env.put(javax.naming.Context.SECURITY_CREDENTIALS,
getParameter("java.naming.security.credentials"));
AppitUtilities.setEnviroment(env);
(AppitUtilities is a singelton which stores the information for later use)
snip of code which we uses to collect
final StringBuffer homeName =
new StringBuffer("com.telenor.mobil.planit.");
homeName.append(moduleName.replace('/', '.'));
homeName.append(".ejb.");
homeName.append(remoteInterfaceName);
homeName.append("Home");
if (context == null) {
context = new InitialContext(env);
}
final Object homeObject =
context.lookup("java:comp/env/ejb/" + moduleName + "/" +
remoteInterfaceName);
final Class homeClass = Class.forName(homeName.toString());
final EJBHome home = (EJBHome)
PortableRemoteObject.narrow(homeObject, homeClass);
return home;
}

OT: Excellent new EJB 2.0 CMP book available
I apologize that this is off topic, but its probably of interest to everyone here. For anyone interestred in EJB 2.0, there is a great book available at: http://www.mvcsoft.com Its included in their persistence manager product. BTW, that persistence manager is a complete implementation of EJB 2.0 PFD, so if you want to get a head start you can. Even if you don't need their code, the included PDF book is worth more than the $28 they ask for it. (No, I don't have anything to do with them... I just think its a great product that everyone can benefit from). Cheers! Jim

Fault Tolerance in orion server's JMS service
Hi, Does anyone has the idea about fault tolerance in Orion application server's JMS service. And how to set it up. 1) One JMS client how to talk to more than two orion application servers' JMS service at the same time. 2) How to setup and register more than two orion server's JMS services in another JNDI server?

Why xsl:include seems to try to find files in /Orion folder and not web-app root?
Hi, When I use the xsl:include.. directive, it appears to look in server root dir, and not the web-app root its deployed in. I am not quite sure if this is something to do with Orion, or if all servers operate in this manner and therefore its an error of the XSLT technology. Or..perhaps its an error of the saxon library I am working with. Just wondering if anyone working with Orion and XSL have seen this problem or not? Thanks.
RE: Why xsl:include seems to try to find files in /Orion folder and not web-app root?
Yes, we had this problem. I think its an XSL thing rather than an Orion thing.

Servlet Chaining?
More random stuff from Orion.
I put a statement in my servlet: resp.setContentType("text/html");
All of a sudden I start getting this error:
500 Internal Server Error
Failed to initialize chaining servlet for contenttype text/xml ()
I don't want any chaining, and haven't set any up. How do I prevent Orion
from trying to chain this kind of stuff?

Re: Why xsl:include seems to try to find files in /Orion folder and not web-app root?
If you read the xalan source, you will see that this is a problem with xalan. The method that determines the location of the included file is written to be file-system and URL based. If has no concept of calling a method like "getRealPath()" to get a path relative to your webapp. The code is a mess. The xalan folks should rewrite this complicated code to simply call an interface that the programmer provides. Then your interface would be called to locate a file, allowing you to apply the getRealPath() method that you really want it to use. I am not sure if Xalan II addresses this or not. The only way Orion could fix this is to patch the xalan code, which I think would be a very bad idea. The way that we solved the problem was to pre-compile the xsl pages in place in our development tree, which presented XSL with a simple file-system to locate included files. We then load the compiled pages for XSLT processing. This also speeded up processing times. tim.

RE: Why xsl:include seems to try to find files in /Orion folder and n ot web-app root?
Orion should just replace Xalan for Saxon anyways... and use TraX instead of a propietary interface to Xalan...

RE: Why xsl:include seems to try to find files in /Orion folder and not web-app root?
When you run Orion, are you starting it from /Orion? Try starting it from a different directory, and see if that changes where saxon searches for includes. My guess, is that it's just looking in the working directory by default. Look through the saxon doc's to see if you can set a property to tell it where to search for docs. I remember seeing something similar to this in Xalan.
