• Class not found in the applet using 2 jar files

  I have an applet that worked for many years as a stand alone or connecting directly to a database of derby on my home server. I just changed it to connect to MySQL on my ISP via AJAX and PHP server.
  
  I am now getting a class not found error in my browser, probably because I'm stuffing by the class path.
  
  The HTML code that I use to call the cmdlet is:
  

  <applet code="AMJApp.class" 
  codebase="http://www.interactived.com/JMTalpha" 
  archive="AMJ014.jar,plugin.jar" 
  width="500"height="500" 
  MAYSCRIPT style="border-width:0;" 
  name="jsap" id="jsap"></applet>

  The AMJ014.jar contains the applet and the support of class files.
  
  The error message is strange for me because it refers to a class, I noticed on another web page, but that has nothing to do with my applet. In any case, the message in its entirety is:
  

  load: class NervousText.class not found.

  I recompiled those classes with the following commands:

  javac -source 1.6 -target 1.6 -Xlint:-options -classpath "C:\Users\MJHIPP\Documents\Current\Java\CodeLocal\AMJ110920\plugin.jar";"." JSHelloWorld3.java

  JSHelloWorld3 always works for me and AMJApp still does not work, but the error message has changed:

  I got different results. The JSHelloWorld3 now works for me (and AMJApp still does not work).

• What "vsphere client lib" or "data-services - 1.0.0" jar file to use in client plugin vsphere-web

  My client plugin project vsphere web contains the two files jar "vsphere-client-lib" or "data-services - 1.0.0. These two jars has many common classes with identical or different method signatures. I used the DataException class in my code that uses the signature of the method of the vsphere client file - lib.jar.

  When I build the project, then sometimes data-services - 1.0.0 jar file gets loaded first and so, build becomes due to a lack of signature of the method.

  I need to know why there are so many classes common to these two pots?

  Can we use only single (also available in the sdk directory) jar of vsphere-client-lib pot instead of data-services - 1.0.0 jar in plugin?

  We can achieve all features using vsphere-client-lib pot instead of data-services jar file - 1.0.0.

  Simply compile your Java with client/vsphere-Java code - lib.jar.  I don't know why you use data-service - 1.0.0 (and where you found it). It is not part of the SDK and is not the doc or samples.

• An Extension using an external JAR file

  Hey,.
  I read this blog entry:
  -[http://blogs.oracle.com/jdevextensions/entry/adding_exteneral_jars_to_an]
  and the thought that maybe that is it, but unfortunately will only work if the jar is deployed with the installation of JDeveloper.
  I use in my extension jar files that I made myself, and even if I can get around this problem my copy just jar files to hand to the place where they are supposed to be, if I export the extension, it will not work on other PC.
  
  So what I need to do, it's somehow include the jar file in the deployment. I tried to add a new group of files for the libraries in the deployment window, but unfortunately, that has not helped at all.
  
  Thank you for your time and I hope someone can help me.

  Couple of things possible.

  It is probably just a thing of packaging in the forums, but make sure externally: part is all on the same line as the Bundle-Classpath entry.

  Also remove the space between the "external: ' and the ' $ORACLE_HOME$".

  One last thing, is in the previous post, you got the mon.jar in a 'test' under extensions folder.. In this example, it seems you are trying to call it directly from the Extensions folder.. This could be the main issue.

  Let me know if these elements help at all.

• Memory used by the Windows executable jar file

  I wrote a java program that locates my position of mouse pointer, and then it moves on the screen using the Robot class. I created a file executable (executable) jar of this java single file and executed. Then I went to Task Manager processes list and saw that the exe is 11MB, which seems pretty huge for me. Anyone know why its occupying 11 MB of memory? And is it normal to occupy this physical memory much?

  Only 11MB? What is your problem? In order to execute a jar file, the JAVA virtual machine must be loaded into memory, so this 11 is actually JVM + your jar file, as well as all resources used.

• can I use JAR files in flex?

  Hello
  I'm new to Flex and we create a web application.
  
  Can I use JAR files I already have and create the front-end server by using Flex?
  
  Thanks in advance.
  
  

  jar files are 'archives java' and are usually full of java class files.

  Flex use actionscript, java and is a technology on the client side.

  You can write your web application based on java, that server is using jar files on the side.

  the flex application would communicate with your server through typical HTTP, as javascript client-side can communicate with your server.

  so I guess the answer is YES, you can use what you want on the server. makes no difference to flex.

• Problem in the visualization of a converted JavaHelp (jar) file (created using RH2002 to RoboHelp X 5)

  Hello
  
  I have a (compressed javahelp) javahelp project created using RoboHelp 2002. The output files are jar files.
  
  The source files are .mpj. When I consult the existing jar files without converting the project to the .xpj I am able to view the jar files.
  
  However, this project should be upgraded to RHx5. The conversion of (.mpj to .xpj), everything seems to work fine and javahelp files are generated. But when I try to view the jar files, nothing is displayed.
  
  I get the following error. Please see below.
  
  Everyone comes across something similar? I have to take care of, before moving on to .xpj? I can't locate the file glo.xml in HR.

  The question of the visualization of jar - resolved files.

  Hi all

  JavaHelp requires the Helpset file and files of navigation to build and display properly. In this case, he was not able to locate the a navigation files not be generated (unless I chose to create JavaHelp compressed with source files).

  I don't know how the generated navigation files in 2002 to HR, but when you have an existing (.mpj) project that must be upgraded to .xpj, it is important to generate JavaHelp with the source files for the first time.

  Once it creates all the files of navigation and the jar file is visible, I can go back to the option of creating just the JavaHelp Tablet and can also display the jar file.

• FileNotFoundException, when you use a template stored in a jar file

  Hello
  
  Using Jdev 11.1.1.3.0 I created a JSF page template in a project and has been in the form of ADF library JAR file. In a second project, I added the library and I could see my model in the drop-down page templates. I created a new page based on this template, but when I run the page I get an exception FileNotFoundException indicating the name of the template file that I created in the first draft. Any idea?

  Make sure the JAR file that has been added to your project libraries has the 'default deployment"check box selected.

• Jar file does not not - in double file source error

  Hello

  I use the plugin Eclipse + BB 1.3.0 and I do a cross-platform for BB + Android app. I've extracted some of the pure java source files, no blackberry or Android specific methods or imports and put them in a jar file. I did it in eclipse by right-clicking on the project-> export-> Jar and selecting files in my project I want to add in the CONTAINER.

  Then, I deleted the files in my project, I just add in the CONTAINER so that they are only in 1 place at this stage. Then on the command line as I type:

  preverify -classpath ../lib/net_rim_api.jar myfile.jar
  

  Now, as I understand it, I should have a file JAR that I can use in eclipse and also the BB JDE.

  I tried to add the JAR directly to the project in Eclipse. Didn't ' work (gave the 'Module review errors'). I then created a project, assign the 'Library', adds that the POT and made 'exportable' and 'export '.

  The initial project can import the classes, but that's all!

  In eclipse, I get an error saying that there is a definition "duplicate" for one of my classes. In the console, it compiles the pot very well, but its when its compilation of the main project I get this error. But I deleted the files in the project and cleaned and refreshed, and deleted the "deliverables" folder then all *.cod and .debug files are deleted.

  Its quite frustrating!

  IF anyone can help, I would be very grateful!

  Thank you!

  Too bad
  I fixed it by adding the jar again to the main project in eclipse, and this time I just checked it in "order and export.

• Problem with several adapters and Jar file included in a service.

  This error occurs very often and it's strange because I place the cards together in a same way. Here is the OSGI layer and contaxt bundle files:

  < constructor-arg ref = "dataServiceExtensionRegistry" / >

  interface = "com. VMware.vise.Data.Query.PropertyProviderAdapter"/ >

  < osgi:reference id = "dataServiceExtensionRegistry".

  interface = "com. VMware.vise.Data.Query.DataServiceExtensionRegistry"/ >

  And I really don't know why this isn't a job.

  The second problem is that I have another project with classes and I want to export it to a jar file. When I do this I also want to include this pot in the bundle, but when I change the ant file it does not work on virgo.

  Any help will be appreciated.

  Kind regards

• EchoSign version 20 jar file?

  Hello

  I'm new to Echosign and I got a task to upgrade to version20 echosign, currently we're using Echosign version15, but could not able to find Echosign.jar anywhere, can someone help me on this? May I know where you guys uploaded the new file Echosign.jar? I spoke with several types of customer support and no one understood what I'm looking for...

  Please help me to find/get the Echosign.jar file to version20.

  If some of you do not know this Echosign.jar file, then here is a simple explanation,

  EchoSign was an Echosign.jar file in their Web site, developers download the jar file, place it in their way of compiling, so they can import and use Echosign classes/methods as below

  Import echosign.api.clientv15.dto.ArrayOfFileInfo;

  Import echosign.api.clientv15.dto.CancelDocumentResult;

  Import echosign.api.clientv15.dto.DocumentCreationInfo;

  Import echosign.api.clientv15.dto.DocumentKey;

• packages and JAR files

  Normally, you would run javac from the 'src' directory, so:

  javac [options] com/mycompany/whatever/package/MyClass.java
  

  It will then automatically find or compile all the other classes that are correctly under 'src' under their packages.
