Java Forum / General / April 2006getTextContent alternative
Hi, I have a java application using JDK 1.5 and now need to run the same application on JDK 1.4. I have used a function "getTextContent()" that is available in JDK 1.5 and above org.w3c.dom.Node nChildlist; nChildlist.getTextContent() // works fine on JDK 1.5 but gives following error in JDK 1.4 cannot find symbol method getTextContent() Has anybody encountered similar situation ? What is the possible workaround for the same ? Any solution for the same is welcome Thanks , RDH > Hi, > I have a java application using JDK 1.5 and now need to run the same [quoted text clipped - 10 lines] > What is the possible workaround for the same ? > Any solution for the same is welcome I know _nothing_ about the API you are using but, by looking at the API for Java 1.4.1, I saw a method in the same class - org.w3c.dom.Node - called getNodeValue(). Maybe that would work?? -- Rhino > Hi, > I have a java application using JDK 1.5 and now need to run the same [quoted text clipped - 13 lines] > Thanks , > RDH Well, if it is "available in JDK 1.5 and above", what made you think it would work in an earlier version, when it was not available? That's like saying "Airbags work in my 2005 Honda, but didn't work on my 1957 Chevy - why not?" Your solution is: 1) upgrade to 1.5 (i.e., buy a new car that has airbags) 2) Write your own method that does this (i.e., install your own airbags)  SignatureFred L.

Kleinschmidt > Boeing Associate Technical Fellow > Technical Architect, Software Reuse Project (Asonishingly OT.) Hi, Fred. That, "Software Reuse Project," sounds interesting; I googled but didn't find anything Boeing-specific in the first few pages; and the search on boeing.com for that phrase yields no results. I preume that, as you have the reference in your signature, you're not bound to silence: can you elaborate on the project? Methods, processes, guidelines, conclusions, etc.? I know nothing about such matters, but I'd have thought that commercial airline software is on a par with military software projects, which, when last I checked, were overwhelmingly ADA, because of its rigourous (if marvellously expensive) provability. Do Boeing use OO in commercial aircraft software design? And particularly, given this group, what do Boeing use Java for? .ed -- www.EdmundKirwan.com - Home of The Fractal Class Composition Hi Ed, Please donot modify my original post!

No, no. You have misunderstood me. I doubt if anyone else is paying any attention to this at all (or if they are, it's because they find it moderately entertaining). The purpose is to waste /your/ time... ========== More seriously. The is a Usenet newsgroup (you do realise that you are using Usenet, don't you ? Nothing at all to do with Google). It's a discussion forum, rather than (as you seem to imagine) a help-desk. It's a "place" where people gather to discuss matters of mutual interest. You may have started a thread on one topic, but if anyone else finds anything in that thread (obviously relevant or not) that they want to pursue, then that is (within the bounds of civility) their right. You /started/ the conversation, you don't /own/ it. Maybe you didn't realise that that's how Usenet works. You will (this is not intended as any kind of insult) find Usenet much more friendly (and helpful) if you learn the few simple rules about how it works. -- chris Hi LTP, How come you in JAVA group ??? This is not a GAMING group where keep sending your baseless and useless lessons. So better not to change the technical discussions to topics of your interest... Hi Chris, >>You will (this is not intended as any kind of insult) find Usenet much more friendly (and helpful) if >>you learn the few simple rules about how it works. Yes, i have found this group (and other too) very informative. Also, you have full right to put your words across. Anyways, i found solution to my problem through some research. Thanks Rhino and Fred for your sending your useful suggestions. RDH rohit schrieb: > Hi LTP, > > How come you in JAVA group ???

You have posted several messages here that only contained links to websites full of advertisements with questionable value. You have never helped anyone out. You don't pay attention to the nettiquette (quotings). *You* have startet to post messages that don't belong here ("Please donot modify my original post!"). You are completely out of your mind demanding that Ed, Luc or Chris should not discuss anything else but your problem. If you continue like that, it is very likely that nobody will even bother to read your postings. Timo > Hi LTP, > > How come you in JAVA group ???

IF anybody can throw some light on following issue: Hi, Operating System : Mac OS X 10.3.9 Java version: 1.4.2 I have an application that uses getTextContent(), setTextContent() which are not present in JDK 1.4.2 so I am in process of adding/using JAXP 1.3.2 on JDK 1.4.2. Below are the steps I tried for the same but still couldnot resolve the issue : 1. Downloaded JAXP 1.3.2 from https://jaxp.dev.java.net/files/documents/913/28792/JAXP_RI_20060217.... and unpacked the same using java -cp . JAXP_RI_20060217 (There is another step written in the URL to compile using jDK.1.4.2 with source/target = 1.4, i couldnot get that point so omiited for the time being) 2. Placed the files dom.jar, jaxp-api.jar, sax.jar, xalan.jar, xerecsImpl.jar at following path: /Systems/Library/Frameworks/JavaVM.framework/Version/1.4.2/Home/lib/endrosed. 3. And recompiled the project. Using JBuilder 2005 for building the application. But still the application couldnot get the functions, getTextContent and setTextContent As per my understanding the application is not able to connect to these jar. Do we need to explicitly specify the path of these jars ?? I hope similiar issue might have been faced earlier too ?? What can be the possible solution? Regards, RDH > Operating System : Mac OS X 10.3.9 [...] > 2. Placed the files dom.jar, jaxp-api.jar, sax.jar, xalan.jar, > xerecsImpl.jar at following path: [quoted text clipped - 11 lines] > > Do we need to explicitly specify the path of these jars ?? If the problem is that the application can't find the JAR, try adding those JARs to your build path. Hopefully JBuilder 2005 has an option for configuring the buildpath. But the problem might be that no classes in those JARs actually define the getTextContent() and setTextContent() methods. Did you check the documentation for those JARs to check if they do define those methods? - Oliver Yes, these API are exposed. I have found other alternative but donot know how correct is it node.getFirstChild().getNodeValue() Will the above serve same as getTextContent() ? Rohit > Yes, these API are exposed. I have found other alternative but donot > know how correct is it > > node.getFirstChild().getNodeValue() > > Will the above serve same as getTextContent() ? I don't know. Read the documentation and see if they do the same thing. I'm guessing maybe you're doing something to do with XML, but I can't tell for sure from the context I have available to me. If this is XML-stuff (i.e. you're working with the w3c.dom package), I think the two methods don't do the same thing. If node is an attribute, then getFirstChild() will return null, thus leading to a NullPointerException, for example. - Oliver I'm running into the same problem. I've tried putting the JARs in my Classpath and the endorsed directory, and still no luck. Were you able to find a solution to the problem, besides upgrading to version 1.5 of the JDK? Thanks >I posted the query to have some possible solutions/discussions and not >for your SILLY and IRRELEVANT talks. And be sure not to drag the useful >discussions to topics of your own interests. It is called topic drift. You don't own a thread just because you started it. Your imperiousness is offensive to people from many nations, and it having the exact opposite effect to that you desire.

Do you think that your potential helpers are that fickle and stupid that they will not address your question, if they able to, because someone metnioned something else in the thread?

It's not possible. Your original post is still there, unchanged. I think you need to to find out more about how usenet/nesgroups works, and about the etiquette and practices... > Has anybody encountered similar situation ? > What is the possible workaround for the same ? > Any solution for the same is welcome See the table that is in the class JavaDoc for org.xml.dom.Node -- it enumerates the various sorts of nodes, and what getNodeValue() returns for each one. Now, consider the table that is in the method JavaDoc for the getTextContent() method of org.xml.dom.Node. It explains exactly what the method does, for each possible type of node. The method does one of three things: 1. for DOCUMENT_NODE, DOCUMENT_TYPE_NODE and NOTATION_NODE, it returns null. 2. for TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, and PROCESSING_INSTRUCTION_NODE, it returns the same thing that is returned by Node.getNodeValue(). 3. for everything else, it does an in-order traversal of the child nodes of the node, getting the node's contents (or quite possibly recursively calling getTextContent() on the child node) and concatenating them with the contents of the other children nodes. This shouldn't be too terribly difficult to code. Have fun! :-) Cheers GRB Free MagazinesGet these publications absolutely FREE for up to 12 months. There are no hidden fees and no obligation.
