Java DC not deployed with WebDynPro DC

Hi,
I've been testing the DC functionality and I'm trying to create the following:
1) WebDynPro DC (DCA)
2) Java DC (DCB)
DCB has code for reading data from a database table (three classes, one is set as a public part). This code is functioning ok in another WebDynpro project where I've used it as an external jar file located in the lib directory and added to classpath.
DCA has a small table in the view that I'm filling (or trying to) with data from the database.
DCB has one java class as a Public Part. DCA has this PP defined in the Used DC's (DC Metadata --> DC definition --> Used DC's). I can see the DCB code fine from the DCA's view (I can use the methods from the class).
I see no code errors and everything compiles ok. I've built the DCA and DCB separately (Development Component --> Build) before doing the project build and deployment.
When I deploy, I'm getting java.lang.NoClassDefFoundError for the DCB class (User.class) when the program starts. So it seems that the DCB is not deployed with the DCA. I've tried to look at the properties and java classpath but nothing I've done has helped.
Purpose is set to compilation, and there is a
<at-build-time/>
tag in the .dcdef file.
Deployment of normal (no DC) Webdynpro projects works fine and the jars in the lib directory are deployed to the server OK.
Seems like I've tried everything but have found no solution yet. Refreshed every part, re-created everything, re-built, re-deployed etc...
Shortly: how to get DCB to deploy ?
Any help is appreciated here
Kind Regards,
Jari Pakarinen

Hi,
What is the Java DC for then ? If it cannot be used as a part of another DC (deployable unit) then how should it be used ? What is the use if it does not end up at the server with Webdynpro code ?
The scenario I'm looking for is to include Java classes in a Webdynpro project as a part of the project (not jars done somewhere else, I can do that already) deployed to the server with the Webdynpro.
Thank you for your help, I'm not blaming you or anything
Regards,
Jari

Java is not working with Firefox (but is working with Safari)

My computer is showing that Java is not enabled via Firefox. When I try to go into Tools/Add-ons, I see that there is no Java plug-in on that list (though I previously had no problem with Java). When I run software update on my Mac, it tells me my software is all up to date. Not sure what else to do. Java is working in Safari, so the problem is clearly with Firefox. I've tried disabling all my plug-ins, and clearing my cache. Nothing has helped.

Apple has removed support for the Java Plugin2 with the latest Java Update 10 for OS X 10.5 Java version, so the Java plugin is no longer available for Firefox versions and other browsers like Google Chrome that require the Java Plugin2.
There will be fix for this in Firefox 6 or in Firefox 5.0.1 if that version will be released, so that Firefox will find the plugin again.
I don't know if all Java applets will still be working on OS X 10.5 with this fix (Apple recommends updating to OS X 10.6).

HT5268 Just purchased Imac and Macbook pro and upgrades to Mountain Lion. Java will not run with one important site where my Grandson is in Kindergarten out of state with in room camera. What to do. This is very disappointing and non of apple geniuses kno

My new IMac and Macbook Pro are each loaded with Mountain Lion. Have Office for Mac also
When I try to see my Grandson on webcam out of state the login will not activate. For PC use I needed Java and Active X to let it run. My Java is checked as ready to go but nothing happens. Otherwise these are great computers. Please help me through the process. The Geniuses at my apple store can't understand what to do.

By default, OS X does NOT come with Java installed nowadays. You need to open the Java Preferences app found in Utilities; when you do that the first time, it will inform you of the fact and offer to install the product for you.
Afterwards, due to a major security issue we had back in the first quarter of the year, the plugin is disabled by default. You need to revisit the Preferences and enable manually. It will auto-disable if unused in awhile.
Lastly, you may have to adjust which Java instance is being used, the 32-bit or the 64-bit. Default is 64-bit, but some applets crash & burn or outright refuse to run in such a platform. You can prioritize which version you prefer by dragging on top in the Preferences.

Java is not working with Firefox 4.0. It was working fine with Firefox 3.6

When uploading photos on Zenfolio, Java was working fine with Firefox 3.6. But when I upgraded it to Firefox 4.0, Java stopped working properly. When I try to upload photos, the Java text opens up with all the programming codes. With Firefox 4.0, I am not able to upload photos into Zenfolio.

Java console not compatible with 6.01 Mozilla update

Since the 6.01 Firefox update, I can no longer view flash panels and some images are not appearing on web sites. I look and found all the java consoles greyed out with the message they were incompatible with 6.01 Firefox. So what do I do now? I also notice that websites suddenly disappear when I did not close them. Please fix this problem.

Hi catnip009:
I can confirm cor-el's information that it is "normal" for the Java Console extension to be disabled in FF6 (see my post [https://support.mozilla.com/en-US/questions/870013#answer-247544 here] for instructions on how to test your Java installation).
When you say "flash panels", do you mean that '''Adobe Flash''' doesn't seem to be working on some web sites with FF6?
If that's the case, then try the following:
First, check your Flash installation [http://www.adobe.com/software/flash/about/ here] on the Adobe web site. If your Flash isn't working or you don't have the latest Flash v. 10.3.183.7, do the following:
# Uninstall Adobe Flash from the Windows Control Panel
# Download and run the [http://kb2.adobe.com/cps/141/tn_14157.html Adobe Flash Uninstall Utility] to clean out remnants of any old installation
# Re-boot your PC
# Run the Adobe Flash Uninstall Utility again for safe measure
# Download the Adobe Flash v. 10.3.183.7 standalone plugin installer (the non-IE NPAPI version) from the FileHippo site [http://www.filehippo.com/download_flashplayer_firefox/10462/ here] . Be sure to download v. 10.3.183.7 (the current stable version) and not a beta test version. '''Save the installation file to your hard drive and do not run the installation from your browser'''
# Install Adobe Flash from the Run command (Start | Run) with the new installation file with all browsers and instant messenger software closed
# Check your new Flash installation [http://www.adobe.com/software/flash/about/ here].
If you also use the IE browser, the ActiveX version of Flash v. 10.3.183.7 for IE can be downloaded from FileHippo [http://www.filehippo.com/download_flashplayer_ie/10461/ here]. If you prefer you can re-install Flash from the Adobe site ([http://get.adobe.com/flashplayer/ here] for auto-detection of OS and default browser; [http://get.adobe.com/flashplayer/otherversions/ here] for any version of Flash), but I prefer using the standalone installers from FileHippo because Flash occasionally doesn't install correctly when you run the installation from the Adobe site via your web browser.

XSLT with java extensions not working with jdk 1.6

Hi,
in as XSL transformation I'm using java functions in some cases. With jdk1.5 this works fine. But when switching to jdk1.6 it seems the java classes are not properly initialized.
See following simple XSL:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="http://xml.apache.org/xalan/java" exclude-result-prefixes="java">
     <xsl:output method="html" indent="yes" encoding="iso-8859-1"/>
     <xsl:template match="/">
     <xsl:variable name="counter" select="java:java.util.Vector.new()"/>
     <xsl:variable name="temp1" select="java:add($counter,'1')"/>
     <xsl:variable name="temp2" select="java:add($counter,'2')"/>
     <xsl:variable name="temp3" select="java:add($counter,'3')"/>
     <xsl:value-of select="java:size($counter)"/>
     <xsl:value-of select="java:toString($counter)"/>
     </xsl:template>
</xsl:stylesheet>
With jdk 1.5 it creates following output:
3
[1, 2, 3]
With jdk 1.6 I get:
0
So I can access the object in jdk 1.6 but adding doesn't work.
Anybody has an idea what could be wrong or how to fix this?

thanx this is the solution. With this construct
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="http://xml.apache.org/xalan/java" exclude-result-prefixes="java">
     <xsl:output method="html" indent="yes" encoding="iso-8859-1"/>
     <xsl:template match="/">
     <xsl:variable name="counter" select="java:java.util.Vector.new()"/>
     <xsl:variable name="temp1" select="java:add($counter,'1')"/>
     <xsl:variable name="temp2" select="java:add($counter,'2')"/>
     <xsl:variable name="temp3" select="java:add($counter,'3')"/>
     <xsl:variable name="temp4" select="$temp3"/>
     <xsl:value-of select="java:size($counter)"/>
     <xsl:value-of select="java:toString($counter)"/>
     </xsl:template>

Java classes not Found in Webdynpro

hi,
I have this problem.
Suppose i have a value node "Emp".
If i am creating a supply function for it,
I cannot get the 'IEmpNode' or 'IEmpElement' . Even if i type it, it gives error. However, if i create a method, these classes are present in the "java native class". I cannot understand if this is a problem with my NWDS 7.0.09 or is my NWDS not working properly??
Please help...It will be rewarded with good points
regars,
pinki

Hi Pinki,
When you have typed the 'IEmpNode' or 'IEmpElement' try to do a 'Organize imports'
On source -> Right mouse click -> Source -> Organize Imports.
That should solve your problems

Java 7 not working with Power Teacher grade book

I have the same issue as Tweeks21 and don't have the luxury, I suppose, of a spare pc on hand. I can do my attendance on Power Teacher but cannot get into my grade book. At this point, I've resorted back to my paper grade book and wait to use the school's pc. I am a bit frustrated and annoyed at the prospects. When will this be fixed. How long will it take to be fixed. Wish Java, Mac, or Power School/Power Teacher had anticipated problem so it wouldn't be a challenge now. I am a bit anxious for a now solution. help!!

Basic problem when jumping the shark and not retaining a bootable backup/clone of your previously good installation. Sorry, but don't have a solution for you. All I can suggest is to File a bug report with Apple. Complaining here is fruitless.

Java Applets not working with Firefox 5 properly

Java Applets work sometime. But after sometime the Java icon at the bottom (near date & time) disappears. After this no matter what I do it does not work. Java Applets are used in this case to draw charts. The same charts come out properly in Internet Explorer. But I prefer using Firefox for its speed. What is the reason for this problem ?

-> Tap ALT key or press F10 to show the Menu Bar
-> go to Help Menu -> select "Restart with Add-ons Disabled"
Firefox will close then it will open up with just basic Firefox. Now do this:
-> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
-> go to View Menu -> Toolbars -> unselect All Unwanted toolbars
-> go to Tools Menu -> Options -> Content -> place Checkmarks on:
1) Block Pop-up windows 2) Load images automatically 3) Enable JavaScript
-> go to Tools Menu -> Options -> Privacy -> History section -> ''Firefox will: '''select "Remember History"'''''
-> go to Tools Menu -> Options -> Security -> place Checkmarks on:
1) Warn me when sites try to install add-ons 2) Block reported attack sites 3) Block reported web forgeries 4) Remember Passwords for sites
-> Click OK on Options window
-> click the Favicon (small drop down menu icon) on Firefox SearchBar (its position is on the Right side of the Address Bar) -> click "Manage Search Engines" -> select all Unwanted Search Engines and click Remove -> click OK
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious Extensions (Add-ons) -> Restart Firefox
You can enable your Known & Trustworthy Add-ons later. Check and tell if its working.

JAVA Patches not deployed properly-System restore back

Hi Experts! recently we had deployed JAVA patches on EP development box but we are facing lot of problems with functionality and etc.Before going to deployment,we took backup for file system as well database.So we are planning to restore it back.My doubt is...Could I need to restore only DATABASE (/usr/sap/sid) or need to restore FILE SYSTEM (OR) Both? Please provide me solution urgently and which path i should follow to retore at file system level?
Thanks,

Hi,
You have to restre both (application + database). If you have taken offline backup then you restore as it is and try again.

Typing and entering in the address bar yields no action(doesn't work)...Also, Java console not compatible with FF8

The past two versions of FF have rendered the address bar useless when entering a web address...still works with links.
Checked Java website...no updates available

I'm using Firefox 22 on Windows 7 64-bit, by the way.
You can very easily replicate this "bug" (or "feature"... ahem) by shift-clicking any hyperlink which opens up a new Firefox window. Immediately hit the "stop" button to stop the page from loading.
If you're fast enough, the address bar will be completely empty and you can't "refresh" or try again or anything.
In my opinion, the URL should be placed into the address bar the very moment that new window opens. I'd appreciate an explanation of why this is not already the case and if it will or will not be the case in the future.
