The documentation at http://jakarta.apache.org/tomcat/connectors-doc/index.html only really covers Tomcat 4.*. Has anyone been able to do this on a Windows or Linux platform? Are there any good resources out there that anyone knows of that I can look to? It seems like everything I find refers to mod_jk2, which I just found out is being discontinued and everything is moving to mod_jk, so I'd like to use something that will be around for a while. All help/information is greatly appreciated. Thanks, Brent == 2 of 4 == Date: Wed, Dec 15 2004 12:36 pm From: "Brent" Juha, Thanks for the checklist.

I want now to add some soapheader data for session mgmt and authorization. I'm building my own WSDD for the service deployment in AXIS and so I'm allowing AXIS to emit the WSDL which describes the services. I want to add something somewhere to direct axis now to emit a SoapHeader in the WSDL which Visual Studio will then swallow and build into my reference.cs class. I've looked and looked. No luck.

That is what is the output or display you want to see the underline? A String on its own does not have any attributes like underline or bold or anything. All it holds are the characters. Is the output just a label? Then the method used by Thomas is the easiest. I've always liked this method. It makes things really easy to customize the display. Is the output a file, then you have to find out what the file format says about underlining if any. ============================================================================== TOPIC: NoClassDefFoundError on UNIX, but not on PC http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/fcd4321ef5ca8215 ============================================================================== == 1 of 1 == Date: Wed, Dec 15 2004 8:28 am From: "clay" Morning, Created a program with Eclipse which pulls in data, formats it, and sends to a web service.

One table is a list of items to be planned (id, name, duration etc), and the other table contains the planned use of those items. There will never be more than 3 or 4 users and they normally don't work concurrently (they also sit more or less in the same office). Of those users, only 2 of them are allowed to edit the item definitions, but all users need write access to the plan table. Planning is always done on a 24 hour basis, so when one planner starts planing a day, the others should only be allowed to plan other-days. I was planing on writing this as a client-only program which would use JDBC to connect to the database directly. A check-out table (recording who has been using which data since when) and an oracle sequence is sufficient for simple collision detection. A full-blown client-server architecture for this setup seems like hitting flies with a sledgehammer (since most of the work is done right behind the gui, the complexity and level of distribution. It wont grow more complex either, since the workload is directly related to the number of hours in a day, and nothing else). The use case would be something like: The user choses a day that they wish to plan, at which point the relevant data for that day would be "checked out" from the database into memory, manipulated off-line and then sent back to the database when the user is finished. Obviously, a user should not be able to check-out data if the data is already checked out, or if they don't have the priveleges to change that particular set of data. Which brings my to my question: are the java.security.Permissions and GuardedObject suitable for this? The java.security package seems to be more interested in protection against nasties than simple, friendly access control. Also, GuardedObject only checks the permissions when you try to "run" the object. I want to be able to show the user what they can and can't do BEFORE they try (a bit like greyed out menus etc). I was thinking of getting the user's name from the OS, loading the permissions as a collection of objects from the database and then checking those permissions while putting the GUI together (setting up overview lists, edit buttons etc). Does anyone have any tips? Am I barking up the wrong tree? Although I'm an experienced programmer, I haven't been writing java for very long and I'm still coming to grips with the API. (It's a "can't see the forest for the trees" problem :-) Thanks in advance for your guidance! Steve == 2 of 2 == Date: Wed, Dec 15 2004 10:25 pm From: Stephen Riehm [yuk!

The java.security package seems to be more interested in protection against nasties than simple, friendly access control. Also, GuardedObject only checks the permissions when you try to "run" the object. I want to be able to show the user what they can and can't do BEFORE they try (a bit like greyed out menus etc). I was thinking of getting the user's name from the OS, loading the permissions as a collection of objects from the database and then checking those permissions while putting the GUI together (setting up overview lists, edit buttons etc). Does anyone have any tips? Am I barking up the wrong tree? Although I'm an experienced programmer, I haven't been writing java for very long and I'm still coming to grips with the API. (It's a "can't see the forest for the trees" problem :-) Thanks in advance for your guidance!

Filename extensions do not mandate the format of the file, or how it is used. At least not generally. ".do" is none of the extensions I've heard Java ever define for anything, so it must be defined by some other thing. This thing, then, can be your client, one of their clients, a third party, the FBI, aliens, whatever. -- /-- Joona Palaste ([EMAIL PROTECTED]) ------------- Finland --------\ \-------------------------------------------------------- rules! --------/ "C++.

Does anyone have any idea (code examples or whatever!!) how I can map a JNDI object in JSP to the previously authenticated user (via JNDI/LDAP) so I can retireive settings, etc. and disply them on a JSP page? I have a <Realm> in Tomcat (<Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" connectionURL="ldap://brandonrha.mb.ca:389/DC=brandonrha,DC=mb,DC=ca"; userSearch="(sAMAccountName={0})" userPattern="BRHA\{0}" userSubtree="true"/>) and as SOON as I log into the secure web area I want to be able to grab that authenticated object (the user) and put it into a JNDIRealm object, and display all their info onto the web page... How can I get access to this specific object? I know how to create a new one, but does that new one map to the current authenticated user from tocat? How can I get access to that authenticated user? Any help or suggestions would be very much appreciated! thanks -Clayton ============================================================================== TOPIC: J2ee example in Jboss http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/d283362ec4397f86 ============================================================================== == 1 of 1 == Date: Wed, Dec 15 2004 2:02 pm From: Flex Il Wed, 15 Dec 2004 13:24:19 -0500, Sudsy ha scritto: >> Good , Now the error changes , now when I digit java >> SimpleQueueReceiver myQueue the error is : >> >> Queue name is myQueue >> JNDI API lookup failed: javax.naming.NoInitialContextException: >> Need to specify class name in environment or system property, or as an >> applet parameter, or in an application resource file: >> java.naming.factory.initial >> >> It's strange because , like I wrote > > So now you have to look at the source for SimpleQueueReceiver and > find out where it obtains the initial naming context.

I try to find a solution there , but I find only questions not reply, I read Jboss documentation , and ,perhaps , I had to add something into jndi.properties, but I don't' know other.

I've always simply processed it with java org.apache.xalan.xslt.Process, but now I'm trying to speed things up, by compiling the stylesheet once, and processing hundreds of XML docs with it. The output is HTML. This is Java 1.4.1 on a Sparc9. The relevant code: in main(): TransformerFactory tFactory = TransformerFactory.newInstance(); translet = tFactory.newTemplates(new StreamSource(xslInURI)); and then, in a method: Transformer transformer = translet.newTransformer(); transformer.setParameter("baseurl", baseurlParam); transformer.setParameter("directory", dirParam); transformer.setParameter("imageurl", imageParam); transformer.transform(new StreamSource(xmlInURI), new StreamResult(new FileOutputStream(htmlOutURI))); The problem is, unlike when using Process, the following bit of XSLT inserts a newline between the </img> and the </a>, which causes the HTML to display an undesirable underscore after cite.gif (which is a small paragraph symbol the user is expected to click to invoke the javascript). In the source for this stylesheet, all the text within the <xsl:if> is on a single line of nearly 700 characters. <xsl:if test="@seqNum"> <a><xsl:attribute name="href">javascript:showCitation('<xsl:value-of select="$citableAuthors"/>','<xsl:value-of select="$citableTitle"/>','<xsl:value-of select="$journalName"/>','<xsl:value-of select="$volume"/>','<xsl:value-of select="$pages"/>','<xsl:value-of select="$citableSectionTitle"/>','<xsl:value-of select="@seqNum"/>')</xsl:attribute><img border="0"><xsl:attribute name="src">/images/cite.gif</xsl:attribute><xsl:attribute name="alt"><xsl:value-of select="$citableAuthors"/> S-<xsl:value-of select="ancestor::*/@sectNum"/> #<xsl:value-of select="@seqNum"/></xsl:attribute></img></a> </xsl:if> - Paul M Lieberman American Psychological Association ============================================================================== TOPIC: JSP EL and explicit error messages http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/65e5ee92bf562a84 ============================================================================== == 1 of 1 == Date: Wed, Dec 15 2004 2:54 pm From: "massdriver" Hi, I sometimes mistype object and property names in JSP EL expressions, and find that no error is generated. It just doesn't evaluate the expression. For example, for an object named foo with a property of name, this would throw an error: <%= foo.getNAme() %> where this won't: ${foo.nAme} Is there any way to make it produce explicit errors in a case like this? ============================================================================== You received this message because you are subscribed to the Google Groups "comp.lang.java.programmer" group.
