Html class with applet tag support ?

Hello,
I would like to load in a swing application, an html file which contains the tag 'applet'. JEditorPane doesn't support it.
Anyone know of an another class ?
Thanks

If all else fails you can get the source code and look to see how appletviewer is implemented. It probably just calls some internal sun java classes.

HTML Page with Applet in JEditorPane

Hi,
I have a JEditorPane in which i want to show a HTML page which has an Applet embedded in it. Is there anyway that I can do this as if I just give the URL of the HTML file it gives me a text field with applet tag written in it.
Or is there any other way that I can embed an Applet in my application in one of Swing components.
Thanks in advance,

Update:
You may want to extend HTMLEditorKit:
public class MyHTMLEditorKit extends HTMLEditorKit() {
    static ViewFactory viewFac = new HTMLFactory(){
       public View create(Element el) {
          if(el.getName().equalsIgnoreCase("APPLET")) {
              Applet app = ...; // create applet from other attributes
          else return super.create(el);
}Check this out. I don't know whether applet elements are included in the parsed document; nevertheless, check it out.

Window with applet tag gains focus prior to new window browser window

setup a :
1. sample index.html page:
<HTML>
<HEAD>
<script>
var _load=function(){window.open('test.html');};
window.attachEvent("onload", _load);
</script>
</HEAD>
<BODY>
<applet code=Index name=Index width=1 height=1 align=baseline>
</BODY>
</HTML>
2. and child test.html window of the above (opened during onload event)
<HTML>
<HEAD>
<TITLE>1</TITLE>
<script>
var _load=function(){window.focus();};
window.attachEvent("onload", _load);
</script>
</HEAD>
<BODY>
TEST PAGE
</BODY>
</HTML>
when a test.html page is opened focus is temporarily shifted back to the index.html page and
only later back to the test.html page (window.focus()) call in that page sets the focus, not always
suceeds, a further code is required to do a retry)
when the applet is removed from the index.html page, problem goes away, it is if the applet tag
has priority in terms of window focus
byproduct of this is also annoying flicker, (while the focus is shifted between index.html and test.html page)
this problem is only happening with SUN JVM (and I dont know if its a defect or by design)
SUN JVM tested:
Java(TM) Plug-in: Version 1.4.2_03
Using JRE version 1.4.2_03 Java HotSpot(TM) Client VM
suggestions, workarounds? appreciate in advance

How to make pack200 work with applet tag ?

Hello All,
Sorry for the cross-post.
I tired getting the advise on java.net forum but with no success. Can someone here please help with this or direct me to right direction.
I am trying to use the pack200 compressed jars for my Object/Applet tag, but not sure how to go about using it.
I have followed the instructions for jarsigned pack200 jars.
http://java.sun.com/j2se/1.5.0/docs/guide/deployme.../deployment-guide/pack200.html
But now how do i use them in my Object tag, what should i name the files in my cache_archive parameter :
example:
something like :
<PARAM NAME = CACHE_ARCHIVE VALUE = "final.jar" />
or :
<PARAM NAME = CACHE_ARCHIVE VALUE = "final.jar.pack.gz" />
renaming : final.jar.pack.gz --> final.jar ??
I tried both the above options but none of them works.

How to get exact height of HTML line with SUB tag in JTextPane?

Hi, this is my first post. I`ve been searching forum for an answer for a week, but didn`t find one.
I have HTMLDocument inside JTextPane(exacty inside my class that extends it - MyTextPane). I want to do some custom painting in JTextPane so I need to be able to know exact pixel witdh for each line in the document. Easy except one thing, when I use SUB tag the width of the line cannot be simply calculated using FontMetrics, because I don`t know if the text inside SUB tag has lower font size and I don`t know its Y offset to normal line.
I tried get these information from HTMLDocument using attributes from leafElements representing lines, but there seems to be a problem too.
I pass this text:
"(1) Line<SUB>jW</SUB><BR>(2) TextB"
to setText method of MyTextPane, this method is overriden so it changes text Font
public void setText(String s) {
super.setText(s);
setJTextPaneFont(this, new Font("Arial",Font.PLAIN,36), Color.black);
}This is how the Element Structure looks like:
Format is Element +": "+elementText+"|"+fontFamily+" "+fontSize
BranchElement(html) 0,22: \n(1)?LinejW (2)?TextB\n|Monospaced 12
---BranchElement(head) 0,1: \n|Monospaced 12
------BranchElement(p-implied) 0,1: \n|Monospaced 12
---------LeafElement(content) 0,1: \n|Arial 36
---BranchElement(body) 1,22: (1) LinejW (2) TextB\n|Monospaced 12
------BranchElement(p-implied) 1,22: (1) LinejW (2) TextB\n|Monospaced 12
---------LeafElement(content) 1,9: (1) Line|Arial 36
---------LeafElement(content) 9,11: jW|Arial 36 <-----------THIS IS THE LOWER INDEX
---------LeafElement(content) 11,12: |Arial 36 <-----------THIS IS just space character '\u020'
---------LeafElement(content) 12,21: (2) TextB|Arial 36
---------LeafElement(content) 21,22: \n|Arial 36
The height of Arial 36 is according to FontMetrics 43(and it really is), but height of the lowerIndex is just 40 pixels(on the screen), not 43 as I would expect. And I still dont have offset, where does the lower index starts paint itself.
Is there any problem with my setText method, so that it changes font style for LOWER INDEX?
I am using JTextPane as notEditable, with just one font style for entire document.
Any suggestion?

Is there any other way to get these information. I just found that I need that information before I put text it in the document.
For example I am would like to generate lines:
paragraph1 - text1
                         text2
paragraph2 - text1
                         text2
                         text3
paragraph3<SUB>some note</SUB> - text1
                                                                       text2
normal text line
I know what font line will be and I know its AttributeSet. I am trying to get appropriate number of spaces (or left indent) for text2,text3...lines. Then I will pass that string to setText method of JTextPane.
I am unable to get appropriate width for "paragraph3<SUB>some note</SUB> - ", since text in SUB tag uses probably different font size.
I am really sorry to bother again. I will think twice what I need before I posting.
You`ve been very helpful so far Stas.
Thanks.

Is there a way to include html link with applet?

I am thinking of writing an applet that would be useful to others, which I would provide for free. In return I would want a link from the pages that use the applet. It is important that the link is search engine friendly, a pure href html link that will provide google page rank to me.
Is there a way to include such a link with an applet so that it can't be removed?

No. You can't force other sites to change their content.

applet tag vs Object tag

As per W3Schools HTML applet tag is not supported in HTML5. Need to use <Object> tag instead of <applet> tag.
For more details follow this link: http://www.w3schools.com/tags/tag_applet.asp
http://dev.w3.org/html5/spec/obsolete.html#the-applet-element
Point 11.2 Non-conforming features
So, I go ahead and the change the code as below depicted.
Below code that is working with <APPLET> tag:
+<Applet+
style    = "position:absolute;border:0px;left:184;top:95;height:180;width:364;"
code     = "jtreeviewapplet.JTreeViewAppletMain.class"
name     = "TreeView"
id       = "TreeView"
hspace   = "0"
vspace   = "0"
align    = "top"
archive = "/Project/HTML/ABC/XYZ.jar,/Project/HTML/ABC/ABC.jar"
MAYSCRIPT>
+<PARAM NAME="onSelected" VALUE="onSelect_Handler">+
+<PARAM NAME="onFinishNormalize" VALUE="onFinishNormalize_Handler">+
+</Applet>+
Here is the snippet, whcih have been changed to <OBJECT> tag so as to support HTML5 in future:
+<OBJECT type=" application/x-java-applet"+
style    = "position:absolute;border:0px;left:184;top:95;height:180;width:364;"
name     = "TreeView"
id       = "TreeView"
hspace   = "0"
vspace   = "0"
align    = "top"
+>+
+<PARAM name="code" value=”jtreeviewapplet.JTreeViewAppletMain.class”>+
+<PARAM name="codebase" value="/Project/HTML/ABC/">+
+<PARAM name="archive" value=" XYZ.jar">+
+<PARAM name="archive" value=" ABC.jar">+
+<PARAM name="scriptable" value="true">+
+<PARAM NAME="onSelected" VALUE="onSelect_Handler">+
+<PARAM NAME="onFinishNormalize" VALUE="onFinishNormalize_Handler">+
+</OBJECT>+
After changing the *<applet>* tag to *<object>* tag , my applet itself is not loading and it gives class not found exception for jtreeviewapplet.JTreeViewAppletMain.class.
(Note: For both working and not working condition, I am using latest JDK 1.7 update 9 for compiling the code and in my system I am having latest JRE1.7 update 9 to run the applet code. I am using InternetExplorer 8 and InternetExplorer 9 browser)
Can anybody help me to find out where I am going wrong?
Edited by: 975931 on Dec 12, 2012 1:24 AM

You might want to stick to the documentation:
http://docs.oracle.com/javase/tutorial/deployment/index.html
and use the deployment toolkit.
PS: use \ tags when posting anything code related. That makes it readable and it keeps the forum from trying to interpret it.

[Needing Help] J2EE proyect with Applet client

Hello, I'm Maximiliano and I'm working in a proyect in J2EE.
I'm using netbeans for developing.
I'm trying to include a applet in my netbeans proyect but the netbeans IDE compile/save the classes in WAR/WEB-INF/classes and that folder it's not public, so i can't call my applet from my index.jsp.
If i move the class file to the root of the WAR it works but the imports for mi ejbs are broken.(Because they're in /WEB-INF/lib)
I've also tried to create a separate proyect for the applet and packaging all in a EAR package (with a simple ejb too) and it's not working either.
What i need is if anyone can tell me how to call my packaged applet from my index.jsp
I know including applets in html with <applet> tag but i cannot resolve the correct path to my applet, or if i have to modify my proyect.
Thanks, Maximiliano.
And example will be much apreciated.

its a very good question actually - I have no idea how to achieve that. My gut feeling says that you certainly want to turn the applet into a separate project, as the applet is basically a client to your JEE environment and not part of the JEE application itself. Turning it into a separate war module seems like the thing to do - perhaps even put it outside your application EAR.
The imports of the EJBs are not going to work in any case, even if you manage to get them on the applet's classpath. Your applet is not running on the server, thus it could only call EJB methods through the remote interface, for which you need a a set of libraries from the server and you somehow need to get the remote interface classes on the classpath of your applet - quite difficult to setup.
If you want to invoke EJB methods from the applet, I would really suggest turning them into jax-ws webservices as that makes it such that you don't need any additional libraries to be able to do it. The Java 6 runtime already has jax-ws 2.x inside it, and it is dead easy to call a webservice from a client application.

Can't create dynamic html elements with jsp????? important

Hi All,
I am having problem creating dynamic html elements with jsp tags, i have tried to use EL and java scriplet, both of them don't work.
i am trying to create dynamic menu in my "rightMenu.jspf", based on, if user has logged in or not.
some like this!
<jsp:if test ="${validUser == null}">
some simple text menu here
</jsp:if>
but it is not working. it simply loading all and images with in statement, regardless of whether user has logged in or not. i think some how if statement is not working properly.
"validUser" is a session bean, which is not creating at this point, it will created when user will log in successfully. and also this session bean does not exist at the page, where i am trying to check that .
Is there any way to create dynamic values in jsp. It is really important, is there any body who help me in this matter. i would be really grateful.

hi jaspre,
thanks for replying me. you know what, is it not something wrong with web.xml file. i remember once, i deleted some from there, a property with "*.jsp". i can't remember what exactly was it though.
all if statements works on files ending with extension ".jsp" but don't work only on with extension ".jspf". there must be to do with this.

Get JSP file to run with an applet tag under JDeveloper

I Created an applet and an html file under JDeveloper. with the applet tag in the html file.
when I run the html file the applet runs perfectly.
I Created a jsp file in the same project with the applet and the html file under JDeveloper. I copied and pasted the applet tag from the html file to the jsp file.

Hi,
I meet the same problem and can not get a solution from this forum or other forum in internet, either.
Have you already solved this problem? Can you tell me your solution? thanks in advance.

JDK 1.4.2_10; problem with applet/classpath/OBJECT tag

I'm supporting an applet that needs to run in JDK 1.4.2_10 in order to work. (I don't own the code, so I can't fix the issue)
I'd like to force that particular applet to run under JDK 1.4.2_10, but allow other applets to run on the current default JVM.
I'm trying to do this by using the JDK's htmlconverter.exe utility to force the use of JDK 1.4.2_10. That part is working as expected, but I'm experiencing a side effect.
The problem is that, when I use the OBJECT tag instead of the APPLET tag, the browser attempts to download the class with this URL
http://hostname.here.com/app.testing/app.testbed/classes/appls%2fDOLARS%2fuser%2fApplet%2fclass.class
instead of this URL
http://hostname.here.com/app.testing/app.testbed/classes/appls/DOLARS/user/Applet.class
The second URL works; the first does not. When I use the APPLET tag, it generates the second URL and downloads the class successfully.
I'd like to a) use the OBJECT tag. b) get it to use the correct URL to download the Applet.class file. What do I need to do to make this happen?
Thanks,
Tom Valesky

ER: HTML Applet tag syntax warning - or HTML syntax checker for JDEV.

Hi,
I just spent ages (an hour or two) debugging an applet and it turned out that I had left a comma "," out of my 'archive=..' parameter of the 'applet' tag in the HTML :-(.
E.g. I had <applet code="x" archive="a.jar b.jar, c.jar, d.jar"> and IE simply didn't load 'b.jar' so I got the usual 'class not found' exception. After signing every jar and putting every jar in every directory I finally noticed the commas between some of the jars.
I can understand IE not helping me load an Applet since, from MS's point of view, that is evil Java code, but JDev must know the syntax of a HTML applet tag too so it could highlight the error for me.
Alternatively does anyone know of a HTML checker plugin for JDEV?
Regards,
Simon.

No comments?
I've been looking around for a HTML syntax checker and there are plenty around - just google "html validation". None so far have picked up the missing comma in my busted applet tag. I guess with a missing comma it just looks like a file name with a space in it anyway.
I still think JDeveloper could flag semantic errors like this at development time.
Cheers,
Simon.

Run applet with object tag

Hi people.
I need your assistance in my problem.
I try to run the simple applet (from Java Tutorial Documents):
import java.applet.Applet;
import java.awt.Graphics;
public class HelloApplet extends Applet {
public void paint(Graphics g) {
g.drawString("Hello Applet!!", 10, 10);
with a help of two different HTMLs.
First with an <APPLET> tag:
<HTML>
<BODY>
<APPLET CODE="dir1.class" WIDTH=150 HEIGHT=25>
</APPLET>
</BODY>
</HTML>
Second with an <OBJECT> tag:
<HTML>
<BODY>
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
     codebase="http://javaweb.eng/plugin/jre-1_2_2-win.exe#Version=1,2,0,0"
     align="left" border="0" width="100%" height="100%">
<param name="code" value="dir2.class">
<param name="codebase" value="./">
<param name="type" value="application/x-java-applet;version=1.2">
</OBJECT>
</BODY>
</HTML>
The problem is that in case of <APPLET> tag everything is OK.
In case of <OBJECT> tag the applet don�t run.
And that is only on my machine.
On the others everything is OK in both cases.
HELP!!!
My machine properties:
     Win95
     IE5.5
PlugIN: jre1_2_2-win.exe

Hmmm... I've already seen the Java Plugin going mad if you make too much experimentations with it.
My advice : uninstall it properly and make it be reinstalled by the automatic plugin installation of IE (just by loading the HTML page with the <OBJECT> tag).
I hope it will work...
