Network UI element and Java 8

Hello everybody!
We are using the "Network" UI element (JNet) in one of our WD Java applications (NW 7.3.1 SP 11). This element consists of an obviously unsigned Java applet (which my local Java 7 JVM complained about for some time). Anyway the applet was working o.k. and the defnied Graphs were rendered (almost) as expected.
Today, I updated my local JVM to Java 1.8.0_45. When using my WebDynpro application, my Browser (IE9) shows the applet area with the Java wait logo, then complains about the unsigned applet as before. When I decide to execute the applet anyway, the applet area turns white, then light blue, but nothing else happens. No graph gets rendered. The same behaviour can be seen using Firefox 32.
The java console essentially shows nothing except the JNet version:
Java-Plug-in 11.45.2.14
JRE-Version verwenden 1.8.0_45-b14 Java HotSpot(TM) Client VM
0
ACF version: 7.1000.1.07
JNet 1.1342.15002
UR L&F version: 7.1000.0.12
What did I do wrong ? Did anyone come across this behaviour ? Is there any patch available that resolves the "unsigned applet" problem or can we get a newer version of this applet somehow ?
Regards
Michael

Hi Ravi!
Yes, we added our portal URL to the JVM security exception list when we upgraded the local JVM to Java 7.
I would like the JNet applet shipped with the WebDynpro runtime to be signed, though, to avoid all these complications. Since the "Network" seems to be an official ui element, I'd expect it to be up to date, to be patched to work with current JVMs and so on. Maybe we missed some notes or patches ?

Michael

Network programming C and Java

Hi
I'm new to writing client/server programs.
I have a solaris box and I have a server written in C.
I like to write a java client to talk to the server.
Are there web sites here or elsewhere that would show
examples of that ?
FULLY Appreciate any help.

jschell
thanks for your response.
I dont quite understand what u mean by definition.
Do you mean the C struct of the message sent ?
DMINT32 is the regular primitive data type
long int
my C server header file contains:
extern struct empm_rec_struct {
     DMINT32 ml;
     DMINT32 lm;
     DMINT32 mm;
     DMINT32 boolean;
     DMINT32 rollover;
} current_empm_rec;
struct empm_rec_struct temp_empm_rec;
/* struct to send to client */
extern struct MsgStruct {
     struct empm_rec_struct msg_rec;
     DMINT32          index;
struct MsgStruct msgStruct;
I then tried sending this struct with send( ):
eg:
i = sprintf(str, "msgstruct ml %d\n",msgStruct.msg_rec.ml);
          if (send(new_fd,str, 10, 0) == -1)
     perror("send");
but my java client only show:
msgstruct
that's why I need an example like mine where the java client sends a "pulse"
to the server, server sends the struct msg and then client prints them out.

Very big problem with JSF about FORM and "id=" for HTML form's elements and

I have discovered a very big problem with JSF about FORM and "id=" for HTML form's elements and java instruction "request.getParameterNames()".
Suppose you have something like this, to render some datas form a Java Beans :
<h:dataTable value="#{TablesDb2Bean.myDataDb2ListSelection}" var="current" border="2" width="50%" cellpadding="2" cellspacing="2" style="text-align: center">
<h:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:outputText id="nameTableDb2" value="#{current.db2_name_table}"/>
</h:column>
</h:dataTable>
Everything works fine...
Suppose you want to get the name/value pairs for id="nameTableDb2" and #{current.db2_name_table} to process them in a servlet. Here is the HTML generated :
<td><span <span class="attribute-name">id=<span class="attribute-value">"j_id_jsp_1715189495_22:0:nameTableDb2">my-table-db2-xxxxx</span></td>
You think you can use the java instructions :
Enumeration NamesParam = request.getParameterNames();
while (NomsParam.hasMoreElements()) {
String NameParam = (String) NamesParam.nextElement();
out.println("<h4>"++NameParam+ "+</h4>);
YOU ARE WRONG : request.getParameterNames() wants the syntax *name="nameTableDb2" but JSF must use id="nameTableDb2" for "<h:outputText"... So, you can't process datas in a FORM generated with JSF in a Servlet ! Perhaps I have made an error, but really, I wonder which ?

While I certainly appreciate ejb's helpful responses, this thread shows up a difference in perspective between how I read the forum and how others do. Author ejb is correct in advising you to stay inside JSF for form processing if form processing is what you want to do.
However, I detect another aspect to this post which reminds me of something Marc Andreesen once said when he was trying to get Netscape off the ground: "there's no such thing as bad HTML."
In this case, I interpret ungar's request as a new feature request. Can I phrase it like this?
"Wouldn't it be nice if I could render my nice form with JSF but, in certain cases, when I REALLY know what I'm doing" just post out to a separate servlet? I know that in this case I'll be missing out on all the nice validation, conversion, l10n, i18n, ajax, portlet and other features provided by JSF".
If this is the case, because it really misses the point of JSF, we don't allow it, but we do have an issue filed for it
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=127
If you can't wait for it to be fixed, you could decorate the FormRenderer to fix what you want.
I have an example in my JSF book that shows how to do this decoration. http://bit.ly/edburnsjsf2

PS tables for Network Activity elements

Hi,
I am trying to find the tables for Network Activity elements and its relationship with Activity (PS Module).
There are Std BAPIs to get the data.
But I want the table field names since it would be used by the XI team for data mapping.
Thanks in advance

Hi Pranav
Thanks for yr information. we can select the object WBS, and shall be able to view PS texts in overview and create PS Texts.
My requirement rather, question is, can we attach any documents without having DMS. ie., can we assign any of the Windows document which are available in hard disc?
please thorough some light on this and thanks in advance and belated happy diwali wishes to you.

FM for Network header change and activity element change

Hi Sdn,
I am trying to find a FM where we can change the network hedaer details and the activity elements in SAP.
I tried the FM BAPI_NETWORK_MAINTAIN
it is giving me an error saying the reciver function missing.
Thanks
Naresh

Hi Punith, Hi abdul!
Thanks for the reply!
I've gone through the OPSC, but the thing is that here you define a user status profile at network plant level. But I need to define it at network activity level.
The reason why I need this is because we have types of activities. We use network activities for client activities, for internal activities, to identify and follow-up risk management, etc. Each group of activities -since they have different usages- has different user status associated. But as I don't have any way to assign different user status profiles, all the activities have the same statuses, although they will only use some of them.
Thanks!

Thalos.

How can I do to share the array elements between "C" and "Java"

Hi,all
I want to implement the function about this: c and java between JNI can share the same data area. For example, when change the value of the array in java, i can get the same value in c.
I use the function:Xxx* GetXxxArrayElements(JNIEnv env, jarray array, jboolean isCopy)
But i find that the "isCopy" is JNI_TRUE which means that i get the pointer which point to a copy,so i can't get the change
in Java later.
How can I do?Can i set "isCopy" with JNI_FALSE??
Thank u.

No, you can't. isCopy is of type jboolean*, and the value is just set by the call to inform you whether the data was copied or not, but you cannot infulence that.
In fact, the VM might store an array of primitives in a different way as C, and this routine has to convert between the two representations. In this case copying is always required.

Display icons in Network ui element

Hello everybody!
Im trying to display some hierarchies in a Network ui element. Generally, this works fine, but I'm not able to display icons with the elements inside the applet. The examples in the JNet/JGantt Developer Documentation use <icon/>-tags with the path to a gif file in the Type Repository section like this
<type name="SomeTypeName" inherits="SomeBaseTypeName">
<icon space="5">apps/orgchart/chief.gif</icon>
</type>
and the Type Repository documentation tells me to
Specify the relative address of the URL in relation to the code base of JNet.jar
(a file in your own JAR. file: apps/slm/icon.gif, for example). If
the relative path starts with apps, JNet automatically adds the
missing com/sap/jnet. We recommend that you use the relative path
wherever possible, because you can store the icon graphics in the same directory
in Perforce as the type repository.
But how would I determine the relative address of my icon files stored in my web dynpros src/mimes/components/<component name>-folder inside my WebDynpro jar/ear/whatever in relation to the code base of the JNet.jar which - I guess - would reside inside the WebDynpro runtime or somewhere else on the server, but not inside my own jar ? Or am I wrong about this ?
Thanks a lot
Michael

Hi Christian!
That's what I tried in the first place. The result is something like
/usr/sap/XXX/J02/j2ee/cluster/apps/myCompany.com/my~webdynproapp/servlet_jsp/webdynpro/resources/myCompany.com/my~webdynproapp/root/Components/package.path.to.my.component/imagename.gif
but the applet does not find the image files. Since the JNet documentation says to specify the relative path from the JNet.jar code base, I'd have to find out where that is and calculate the relative path, but possibly this will only work inside a single jar (which I don't have since the JNet.jar is somewhere among the portal WebDynpro runtime components, I guess).
Preferrably, I'd like to have a look at a working example using the Network ui component with external icons inside a java WebDynpro. Propably someone has done that before...
Thanks
Michael

Event handling in Network UI element in Webdynpro

Hi ,
I am developing a hierarchial graph using Network UI element.I want to incorporate event handling so that the graph will respond to user actions like on double clicking a node an URL will be opened.I can notproceed with the event handling.
Can anyone tell me the procedure to do this from webdynpro java.
Regards
Nayeem

Hi Nayeem,
The Network UI element has lots of events defined for it which can be handled to get the desired functionality.
Go to the View in which you have added the Network Element, select the Element and go to the
properties tab.
Under events , you can see a list of events defined for this UI element.
Select the event you wish to handle and press the Create button which gets visible once
an event say onNodeSelected is selected
You can then give a name to the action say UserClicked and save it .
In the properties tab of the UI element , the action will be registed against the event .
Now select the event again and press the go button.
It will redirect you to the java editor of the view where in you can place your event handling logic.
Alternatively, if you have created the UI element dynamically then you can add the event to the UI element by using the following code
IWDNetwork network = (IWDNetwork)view.createElement(IWDNetwork.class);
network.setOnNodeSelected(/*Your Action handler already defined in the View*/);

Ashish

JRE 6 freeze browsers and Java Control Panel Applet stops working!

Hello,
this is the second time I got this problem with Java JRE 6 ! First one was a month or two ago:
I have Java JRE 6 update 20 installed on a Windows 7 64bit ultimate. It was working...much time ago...then i found my browser (firefox, google chrome or IE8) was freezing when I open java application or test pages. I tried uninstalling it, cleaning the system with Revo Uninstaller, or CCleaner or JavaRA and reinstalling with no luck. The other problem is the same that user Mass8 had (http://forums.sun.com/thread.jspa?threadID=5372196&start=15&tstart=0)
...my java control panel applet is not working and give me this:
http://www.iouppo.com/lite/pics/df9b61008b5bf9de61a13d8bfa3ddad1.jpg
I tried disabling UAC, running JRE, starting Win7 in safe mode with network...but browser always freeze. It's not a true freeze, with CPU busy at 100% (cpu stays in idle) but it seems to wait for something. It's not a problem with video card driver on my machine, because I can start java control panel from command prompt...and without the noddraw switch, using this command:
javaw -Xbootclasspath/a:..\lib\deploy.jar -Duser.home="%HOMEDRIVE%%HOMEPATH%" com.sun.deploy.panel.ControlPanel
This was the description of my first time.....then I replaced my system with an Acronis image...and I used the system for sometimes....and Java was working until 3-4 days ago! So I did another image of the system with all things working.
Then this morning...I tried the java test page.....and surprise! It's not working anymore!
In these days I think I only disabled UAC and Account virtualization....maybe JAVA saves things there...and then when I disabled UAC (Windows7 deleted those folders and files) it can't find there anymore???? Who can help me?
I don't want to restore my image every month!
My system is 100% virus free and from the last image restoration I didn't visit suspicious sites and so on....I have antivirus and antispyware software...all is perfectly CLEAN. Any ideas or things to try?

I'm beginning to think it's something related to Hybernation after using JAVA....I'm using it very often...and if I use it...and I suspect Java is KO...i try control panel and it doesn't works....then I try with browser and it freeze (or keep waiting...and i can only force to close it)
THEN,
when I reboot my system I get this window
http://www.iouppo.com/lite/pics/09501eb799c165bb25ece8fd3261e41c.jpg
suggesting me to rename the folder C:\Program in C:\Program1 ...and if i don't rename it...java will never work...instead if I allow it...Windows will fix it!......This until...the next hybernation....:(....
try to replicate this...maybe I found where is the problem..

Background Task on Adobe Photoshop Elements and Adobe Premiere Elements Organizer "hangs"

I recently upgraded my software from Elements 10 to Elements 12 and had a bit of trouble. Apparently both 10 and 12 have a way of launching an executable in the background which tends to get "stuck" on my system. I believe the problem may be related to the network configuration and software mix I live with, but I need to confirm my suspecions and find a way to control the problem. Here is what I know... I have always experienced a lot of problems using Elements with my NAS device which is a 1TB usb 2.0 connected disk system attached to my Linksys E3000 Router. When I got the router, the BIOS software did not correctly support NTFS file systems, but subsequent updates eventually made this possible if you formatted the removable drive on a system in NTFS, you could then hang it on the router and "see" the contents, serve them via Windows Media Player, or iTunes, etc., etc. from a computer atteched to the network, or via wirless directly off the router. I archived all my photos out on this file system and have successfully indexed it for use with Adobe Photoshop Elements and Adobe Premiere Elements Organizer, but... When I went to install Elements 12 software I tried to install it without first removing Elements 10, and on a system which had run Elements 10 since the last full reoboot. During the install of 12 under "shared services install" the installation process "Hung" on a background task with a name like "AdobeElementsAnalyzer.exe" which only shows up in Windows 7 task manager as a running process, not as a full program, but because the file was locked by the system, the install hung. I eventually figured out that I needed to start the install of Elements 12 software immediately after having rebooted so that this program was not present in the background, and succeeded in completing an install of Elements 12 on my Windows 7 X64 system. This system required a "special" software download for Premiere Elements, but not for Photoshop Elements which is only apparently avaliable under 32bit emulation mode. I finally got the "shared components" portion of the X64 Premiere Elements to complete an install, and then set about verifying the onversion/upgrade of the indexes to my photos and video stored out on the NAS. The same rogue task which prevented me from doing the install showed up agian, taking all the system resources away from my dual processor Intel chip and refusing to let go. I was forced to terminate it from the task manager. I strongly suspect that my "issues" are in part due to the extrordinary network latency imposed by the drive connection I'm using to index my photos and videos, and I'm looking for a better approach to using the editors against my master catalog of files, as well as figruing out just what I need to do to insure that all the files I have stored on the drive are accessible by the organizer when I need to pull a copy to work on.
A complication is that I have two "legacy" Windows XP systems on my network, a reasonably fast Windows Vista Business desktop, and the Windows 7 X64 processor system which is the most powerful system I have. The Windows file security enhancements to NTFS changed from XP, to Vista, to Windows 7, so files which get saved to the NAS disk inherit a variety of different levels of security under windows. I have occasionally gone to one of my old XP boxes and "wiped" the security settings by resetting everything via Windows XP. Because the NAS is so slow, this process can take several hours and must not be interrupted by attempts to do anything affecting the NAS by any of my other networked computers. To avoid problems with my photo archive, it makes sense to me to do all my editing on copies which have been extracted from the NAS archive and stored on the C: drive (boot drive) of my Win X64 system.
What I seriously need to know is this: When/If I define a "watched" portion of my file system, rather than taking the time to manually import every little change to my photo archives, can I expect the Photoshop Elements Organizer to work properly as long as everything stored on the NAS is stored via the same system which runs Elements with the same active "user" in control so that all the windows 7 file security settings putting stuff on the mapped NAS drive remain properly secured under Win 7 X64? Frankly I don't care if the files appear "read only" to every other system and identity on my network, but I do need to be able to "see" them. I have been able to view slide shows and movies stored on the NAS via both my networked iPad, my Apple TV, and using Samsung's funky android and Windows compatible software. Frankly, I doubt that Microsoft or Apple has full understanding and control of the environment where there is no host "server" other than the eprom based stuff my Linksys E3000 loads to emulate early Windows Media Management architecture, but I mange to get it to work as long as I don't try anything sophisticated with the file permissions. As a fall back, can I expect individual "imported" bits out on the NAS to remain stable if indexed and used only by the Elements Organizer running on my Win 7 X64 system?
I am seriously considering converting an old WinXP desktop into a UNIX box which could be configured as a "Server" for everything stored on the NAS and be done with my problems in return for the power required to run the server all the time so stuff is there when I need it. Any recommendations?

Adobe hasn't said whether it officially supports PSE 7 on Windows 7. But reports are starting to trickle in that PSE 7 works fine on Windows 7 for most people, though a couple people have reported crashes. My PSE 7 seems to work fine, though I primarily use PSE 8 now. This is all very preliminary, and we'll learn more as more people post here.

I have Adobe Premiere Elements and it will not let me export?

I have Adobe Premiere Elements and it will not let me export? It also will not let me login. It says photoshop.com is temporarily unaivalable and to check my network settings. Error 400. Can anyone help me? I need to export this video as soon as possible.

You don't say which version of Premiere Elements you're using, but Photoshop.com was discontinued last year, so you won't be able to log into it.
As for exporting -- it's hard to give you specific information without knowing which version of the software you're using and on what operating system but -- which Share or Publish & Share option are you using and what is happening when you use it?

RDP and Java not playing well together

I have a Windows 8.1 Pro machine set up for RDP that connects to a field device network. The field network is not accessible from the Internet, so the only method I have to connect to the field devices is RDP through the machine. The devices use
Java for their GUI. When I log onto one of the devices in the field via RDP, the amount of memory Java uses goes up and stays up. Every time I log onto a field device, the memory usage goes up and stays up to the point if I hit 25 or so field devices, I get
an Out of Memory error and Java shuts down the main application running on the machine. However, if I log onto the devices directly from the machine, not using RDP, the amount of memory Java uses doesn't go up. The machine has 6Gb of RAM, rebooting it is the
only way to clear out the memory, which gets it back down to a more normal 14%.
Any ideas?

Hi,
What is the result if we connect to a normal Windows system via RDP? We should first find out whether this is a RDP side issue or a JAVA issue.
And for high memory issue, we have a tool named RAMMap to view the detailed memory usage

I'm using a 1D Arrary with 27 different elements and would like to send those data over UDP Write and UDP Read functions.

I'm using a 1D array with 27 different elements. I would like to transfer that data over a UDP connection, and read it back by using UDP connections.
But I would like to read 3 elements at a time (On read side) and send those to 9 different ports.
Note: the data will go to only one PC with one Network Address)
* 1st elements (0,1,2) and send to port #XXX to see those 1st 3 elements.
* continue until the elements reaches up to 27
This is what I have done but I'm finding myself in pitfalls...
Send side:
I'm using a UDP Open connection on send side to send my data. So with selected a Source Port, I have created a UDP Op
en connection. I�m using only one source port to send all the data across the channel. I would like to read 1st 3 elements and send those data across with an assigned Destination port. I would like to do that for 9 times b/c there are 27 elements in the array. So I�m using a For Loop and setting N count to 9. So I�m not getting any errors when I execute and no answer on the other side at all.
Read side:
I�m using a UDP Open connection to read in the data with port #. I�m using while loop to with Boolean inside by making a true all the time. Inside that While loop, I�m using For Loop to read the 3 elements data a time and send to a right port address. (As start out I was just trying to see if it works for only one port).

You are not getting any errors because UDP is a connectionless protocol. It does not care if anyone receives it. Your example will work fine with the following considerations.
(1) Don't use the generic broadcast address (255.255.255.255).
(2) You are listening on port 30000. So why are you sending to port 1502, nobody will receive anything there.
The destination port of the outgoing connection must match the server port of the listener. (The source port is irrelevant, set ot to zero and the system will use a free ephemeral port).
(3) On the receiving side, you are not indexing on the received string, thus you only retain the last received element. Then you place the indicator outside the while loop where it never gets updated. :-(
(4) Do yourself a favor and don't micromanage how the data is sent across. Just take the entire array, flatten it to string, send it across, receive it, unflatten back to array, and get on with the task.
(You can do the same with any kind of data).
I have modified your VI with some reasonable default values (destination IP = 127.0.0.1 (localhost)), thus you can run both on the same PC for testing "as is". Just run the "read" first, then every time you run "send", new data will be received.
