RE: error Ljavax/servlet/http/HttpServletRequest
Hi, I `m calling a bean from a jsp page that return HttpServletRequest snippet HttpServletRequest req= myBean.getMessage(); out.write(req.getParameter(mess)); where mess is a variable that was set in the bean My problem jsp can`t compile I got the following errors javax.servlet.ServletException: com.MyBean.getMessage() Ljavax/servlet/http/HttpServletRequest; java.lang.NoSuchMethodError: com.MyBean.getMessage() Ljavax/servlet/http/HttpServletRequest; I feel this question should be answered by reading up on Java - it has not much to do with tomcat. The exception you get is easy to find on the web I googled java.lang.NoSuchMethodError and got as first result the Sun javadoc for the class. It's here: http://java.sun.com/j2se/1.4.2/docs/api/java/lang/NoSuchMethodError.html . It says: Thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method. (Now this explanation may be hard to understand if you are not somewhat used to OO terminology. If this is the case I suggest you read up on OO and its use in Java.) Anyway, this means that there is no method in your class com.MyBean called getMessage that returns an instance of javax.servlet.http.HttpServletRequest. It would be interesting to know why you are passing around the HttpServletRequest in this way. It is easily accesible from the JSP page anyway.

RE: java.lang.Class.getResourceAsStream() throws ClassCastException
During initilization of my c3p0 connection pool by hibernate the below printed exception occurs. The exception causes a failure in the c3p0 initilization and thus hibernate and my application. Does anyone know what might cause this behavour? Seems like it is the catalina class loader that fails to cast an object into a org.apache.naming.resources.FileDirContext. I checked the latest source of this class and there is no FileDirContext in WebappClassLoader. From the stack I am guessing that there are class namse in property files that are loaded dynamically. Maybe something is wrong in those property files? What version of tomcat are you using? (Assuming that you are using tomcat that is. Catalina code seem to be involved somehow.) I am not sure if I can help you any further but the folks that can will surely be happy for some details about tomcat versions, platform and so on.

Re: Avoid duplication of database settings
Sorry about the antispammed subject in my previous post. I have an application consisting of a web application and some stand alone java clients. Both the web application and the java clients use a database. The problem is that the database configuration is duplicated. If you are doing it the ant way I recommend using filtering. Thanks for the suggestion. I will have a look at it. Do you know if frameworks like Spring or Hibernate solves this kind of problems? I don't know about spring but in hibernate there is one configuration file that you can share between webapp and standalone clients. (Using it in my current project.) If you only use Hibernate to access your database you will be fine. It is also possible to get the DataSource from the hibernate configuration if you want to access the database directly (for performance reasons). I have some SQL scripts that need the database info so I use filtering anyway both as a way to have the configuration values in one place and as a way to easily build for different environments.

RE: Tomcat 5.5.x and java 1.4.x
The only thing needed to run on 1.4 is the compatibility package, which contains a few class files that are standard in the 1.5 JRE but have to be downloaded separately for 1.4. It's not class files it contains: it's xml and jmx jars. I haven't quoted out of context: I know the details. And just maybe there may be class files in the jar files?

RE: Concept for modeling hierarchical data
Florian Lindner wrote: Florian Lindner wrote: Hello, I'm searching for the best concept of how to use and save hierarchical data. I have a structure like PC file system with meta data. There a folder objects and files objects of different types. Every object have data like permissions, date and author. And they have type-specific data fields like resolution (of an image type) or location (of an meeting type) or ingredients (of an recipe type). What is the best way to store that kind of data? What database is recommendable? What concepts of persistance? Or not using managed persistance and do it manually? If you want to do it manually, a hierarchical tree can be represented by just one table: CREATE TABLE tree ( id INTEGER PRIMARY KEY, parent_id INTEGER ); With managed persistence, be carefull not to configure it to load the entire tree at once. As for a DB, any decent relational DB will do. In this concept I need a table for every type of objekt I want? It depends on if you want the DB to handle data integrity for you. If you are happy to have everything as key-value pairs you can come away with two tables. Add a table with columns kay, values and a foreign key to the suggested tree table. If you want specific data integrity per type you will have to have one table per type. It also seems that some data is there for all types (permissions, date and author). Maybe you want to reuse that definition in one table. In the end it depends on what you will be using this tree of data for, how will you access it and what technology will be used? Will it be read-only or both reads and writes? Volumes? Number of users? If data is to be updated by several users I think youl should definitely use a relational database of some kind. If it is read-only then XML files will be good enough. Hibernate is a good persistence framework to use if you want to do the modeling in XML or Java.

RE: [SPAM] - Avoid duplication of database settings - Number of numbers in MIME From exceeds maximum threshold
Hi, I have an application consisting of a web application and some stand alone java clients. Both the web application and the java clients use a database. The problem is that the database configuration is duplicated. When I change the database settings, I have to reconfigure both the webapp (META-INF/context.xml) and the java clients (mydatabasesettings.properties). I'd like to avoid this duplication. One possible solution would be to generate the context.xml based on mydatabasesettings.properties with an Ant script. Are there any better solutions? If you are doing it the ant way I recommend using filtering. There is a task called filter (see http://ant.apache.org/manual/CoreTasks/filter.html). You put the values you want to use at several places in its own property file for example dbname=mydb, in the places you want to insert it you go @dbname@ instead of the actual name. When you run the filter task all values in the filter property file is put in its correct places. (I use this now to build for different environments. One property file for development, one for test and one for production. But in you case you onle need on file I guess.) If you are using Maven there is some more support for filtering although the ant task still needs to be called explicilty.

RE: JasperException: No tag xhtml defined in tag library associated with uri urn:jsptagdir:/WEB-INF/tags
Hi, I don't know anything about this xtags taglib you seem to be using so just take the following comments for what they are org.apache.jasper.JasperException: No tag xhtml defined in tag library associated with uri urn:jsptagdir:/WEB-INF/tags I would say this means that we are missing a file called tags in the WEB-INF directory of the webapp. The gile is supposed to define the tag xhtml. The reason we get this is the first line in the jspx file: tags:xhtml xmlns:tags=urn:jsptagdir:/WEB-INF/tags snip I have tried downloading the xtags and adding them to the WEB_INF folder in the ROOT directory but this has not helped. Any assistance would be greatly appreciated. Your url to the app seem to suggest that the webapp is called viewscast. You should add the file to tomcatroot/vieewscast/WEB-INF/ rather than .../ROOT/WEB-INF/ . And then there seem to be a conflict between the name of the taglib. The exception misses tags while you are downloading xtags. May be one of those silly things...

RE: Tomcat IIS-redirector help
Hi, I had not added the DLL to the web services extension section until I read your email, however I am still having the same problem. Can someone tell me how to verify that I can execute /Jakarta/isapi_redirect.dll from my vhost? (http://hostname/jakarta/isapi_redirect.dll) ---is this right? No - you should set up a web site in IIS that uses the ISAPI filter to talk to Tomcat. Is there something that perhaps I did not configure somewhere else that could be causing this problem? Probably. I did this recently and followed the guide here: http://tomcat.apache.org/connectors-doc/howto/iis.html . There are several steps to do. Steps that comes to mind: - In your web site in IIS you need a virtual directory that is called jakarta that is mapped to the directory where JK is installed. - Your web site of Web sites should have the ISAPI filter installed. - JK uses 2 property files that is defined in the registry. If you used the installer for JK this should be no problem. Otherwise you need to enter stuff in the registry. The file called uriworkermap.properties should contain the mapping you need to talk to in Tomcat. - The only part that isn't documented is the one you just managed to do regarding the Web Services Extensions. All the details is in the official documentation for JK. Follow the link and good luck with the tweaking.

RE: Tomcat IIS-redirector help
Curious though, I think you mentioned that you added the isapi filter to the web sites container, on not the web site itself, is this correct? Yepp - I think you should be able to do it either way. If you want the filter to be active for all your web sites you can add it at the top level. That's the way I have done it. Maybe it doesn't work if you add it directly on the website itself?
