JSP being interpreted?
Hi All,
Not sure if I am way off mark, but it almost seems as if my JSP is not
being interpreted.
Using the /manager web app, I get my app deployed (I still can't figure
out why my command line install doesn't work) and I publish this page:
==
%@ taglib uri=/WEB-INF/tld/c.tld prefix=c %
html
body bgcolor=white
c:set var=message value=Hi there!/
c:out value=6. ${message}/br/
c:out value=7. ${'message'}/br/
bParameter values passed to this page for each parameter: /b
c:forEach var=current items=${param}
bc:out value=${current.key} //b
c:forEach var=aVal items=${paramValues[current.key]}
c:out value=${aVal} /
/c:forEach
/c:forEach
/body
/html
==
But the result is this:
==
6. ${message}
7. ${'message'}
Parameter values passed to this page for each parameter:
${current.key} ${aVal}
==
Is it possible that my jsp code is not being interpreted?
A bit lost...
Rob

Yes and no. Struts separates the calls business logic (Action classes) to the formatting of the display. The formatting defaults to JSP, but really, can be any resource in your context: another servlet, a Velocity template, etc. The real question is why the JSPs have been banned.

servlet api question
What are the advantages or the reason for the popularity of servlet api vis-a-vis the web server specific api ? Say Netscape server or IIS server also have their own specific api's as well where one could write server side code. But the servlet api is so popular and wide spread and one could argue that java sdk is free but then companies buy the third party j2ee servers like websphere or weblogic. __ Do you Yahoo!? Yahoo!

JSP compile with jdk 1.5 in 5.5.7
Tomcat 5.5.7/8 documentation suggest setting 'compilerSourceVM' and 'compilerTargetVM' to enable jdk 1.5 JSP compilation (along with removing |jasper-compiler-jdt.jar and replacing with ant.jar|) However, those 2 parameter names are not in web.xml's commented list of optional flags. I've tried this in 5.5.8 and in the 5.5.7 distributed with net-beans 4.1 beta. init-param param-namecompilerSourceVM/param-name param-value1.5/param-value /init-param init-param param-namecompilerTargetVM/param-name param-value1.5/param-value /init-param I get an error saying that the [java 5 ] features are not supported in source 1.4 Seems like these flags are not being passed to ant. Are these flags still valid? Can JSPs be compile using Java 5 in Tomcat 5.5.x? I know the docs say that the IBM compiler will be updated to support the Java 5 syntax as soon as possible.

Re: [Slightly OT] MVC approach when JSP are not allowed
You could look into alternate MVC approachs like Freemarker, Velocity, or XSLT; these are processed by a servlet, but allow you to extract the presentation logic into a text-based template file. Also, as others have pointed out JSPs are compiled into servlets; and if you know your deployment target server then they can be precompiled.

Re: Tomcat not running(4.0.6/5.0.19)-urgent
Try putting an html or jsp file in your my_apps folder. I'm not sure what Tomcat does when you navigate to the web app with nothing other than WEB-INF in the web app's folder. When I navigate to one of my web apps the way you're trying, I get a directory listing of the files and folders I have there, but I notice that that WEB-INF is not included in that listing, even though it is present.

Re: Authentication for streaming file (OT)
Have you tried other browsers than MSIE? If it works for FireFox, then
you've probably hit http://issues.apache.org/bugzilla/show_bug.cgi?id=28750.

Slightly off-topic -- Tomcat related
I have a servlet that is invoked by clicking a hyperlink that is rendered
by a JSP running in Tomcat. The servlet receives a file path parameter in
the HTTP request, and then streams that file to the requesting client. I
have a security-constraint/ defined in Tomcat for the JSP, requiring
basic password authentication. However, if I define the
security-constraint/ so that it applies to the servlet also, then the
following error occurs when the servlet attempts to stream the file to the
client.
The browser presents the file info and prompts to save or open the file,
but then when the actual streaming is attempted, the browser reports that
the site is unreachable. This is apparently caused by the lack of any
authentication during the file streaming operation, because when I define
the security-constraint/ so that it applies to the JSP but not the
servlet, the problem does not occur. I don't really understand why it
behaves this way, since the servlet was invoked with proper authorization,
and the problem occurs only when the servlet starts streaming a file to
the client. But it does seem to be an authorization problem, since it goes
away when I don't constrain the servlet for authentication. I can operate
this way, but then my JSP is protected and the servlet is not.
Is there a way to specify authentication parameters during the file
streaming operation? Does anyone have an explanation for what I'm
experiencing? Here's my servlet code:
public class FileSender extends HttpServlet{
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException{
String filename = request.getParameter(file);
File file = new File(filename);
MimetypesFileTypeMap mimeTypes = new MimetypesFileTypeMap
(C:\\Program Files\\Java\\jdk1.5.0_01\\lib\\mime.types);
String mime = mimeTypes.getContentType(file);
response.setContentType(mime);
response.setHeader(Content-Disposition, attachment;
+ filename= + file.getName());
FileInputStream in = new FileInputStream(file);
OutputStream out = response.getOutputStream();
byte[] buf = new byte[1024];
int i = 0;
while((i=in.read(buf))!=-1) {
out.write(buf, 0, i);
}
in.close();
out.close();
}
}
And here's my web.xml. With this configuration, the file downolad fails as
described above. To make it work, I remove the second url-pattern/
element as indicated.

Re: Using RealmBase.Digest(...)
1) If you have catalina.jar in the $CATALINA_HOME/server/lib/ directory, then it's only going to be available to the Tomcat server internal code, not to your web apps. If you want it to be available to Tomcat and your web apps, then you should put it in the $CATALINA_HOME/common/lib/ directory. You don't need to copy it- you can move it there- since that will make it available to Tomcat and all your web apps. 2) As stated in Footnote 19 of the HTTP/1.1 spec, the IANA Character Set Registry (Reynolds, J. and J. Postel, Assigned Numbers http://www.ietf.org/rfc/rfc1700.txt , STD 2, RFC 1700, October 1994.) is the authoritative listing of charset values. However, I noticed that the API for setDigestEncoding() says that the String charset parameter can be null to indicate the platform default character set. I suggest you give that a try when invoking Digest(). Pass it a null String value for the third parameter and see if it works. I think that what you're trying to match is the charset the client browsers will use when the users attempt to authenticate to the realm. If you want to know what your default charset is, invoke getDigestEncoding(). Whatever value is returned is the charset you need all your users to use when they authenticate (or a charset that is compatible within the ranges of characters that the users will be entering). If they will be using other charsets, you should be able to determine what they're using from the Content-Type entity header field in the HTTP request message, and then set that charset value for your realm using setDigestEncoding(). The charset will be specified as a parameter value in the Content-Type field. For example, Content-Type: text/html; charset=ISO-8859-4 See section 14.17 of the HTTP spec; here's the link: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.17 -Mark J Malcolm wrote: I'm writing an app to create user id/pw's in a db for use by realms. I've read the realm HOW-TO page. But I have two implementation questions: 1) the page says: To use either of the above techniques, the $CATALINA_HOME/server/lib/catalina.jar file will need to be on your class path to make the RealmBase class available. I'm doing this in a servlet. The way I typically make jar files avail to servlets is to put them in the WEB-INF/lib dir or in the Tomcat common lib. I don't think I should be making a copy of this jar or moving it around. How do I force a jar into a webapp's classpath? Is there a tag I can put in web.xml to set classpath or add jars? 2) There are three parameters on the Digest() method. The third parm is 'encoding'. What encoding should I be using? I assume it needs to match whatever encoding the realm code is going to use when it compares the digested password. What string do I use for this parm? Thanks.

Re: Tomcat not running
Hello, i have already tested these things which you are telling.When i put some html or jsp files directly ubder my_apps folder i see the list of these files when i type http://localhost:8080/my_apps but my problem is that sometimes i am not able to see this also.it says /my_apps is not available.coming back to your point ya a client can't see the WEB-INF directory.It's kept secret from the client by the server itself.That's why when we run our servlets which we put inside classes folder under WEB-INF we generally call it through a url-pattern which we declare in the web.xml file. Ayaskant Mark Leone [EMAIL PROTECTED] wrote: Try putting an html or jsp file in your my_apps folder. I'm not sure what Tomcat does when you navigate to the web app with nothing other than WEB-INF in the web app's folder. When I navigate to one of my web apps the way you're trying, I get a directory listing of the files and folders I have there, but I notice that that WEB-INF is not included in that listing, even though it is present.

Re: Authentication for streaming file (OT)
Yes, that's exactly my problem. It only fails with HTTPS connections on IE. It works with Firefox (using the built-in download manager or Flashgot) as well as Safari on a Mac. Nice to see, according to a posting in the BZ link you provided, that M$ has decided to label it a feature rather than a bug. I applied the workaround you described in BZ #27122, and it now works properly with all resources of the web app protected by a security-constraint/. Thanks for pointing me to the solution. -Mark Bill Barker wrote: Have you tried other browsers than MSIE?
