No need to use
custom Qt for Jambi – Smar 2 days ago
Thanks to SMAR, I was finally able to resolve this
issue by downloading the an older version of
qtjambi 4.6.3 ( http://qt-jambi.org/downloads/ ). The only problem was that the
designer did not know where to find my jvm which
I solved by adding these two entries to /etc/bash.bashrc:
# custom PATH exports
export JAVA_HOME=/usr/lib/jvm/java-6-sun
PATH=$PATH:$JAVA_HOME/bin
Then I just had to run (everything was in the qtjambi-folder):
designer.sh --> save it as .jui --> convert it with juic into a .java file --> and load it with netbeans :)
Hope this is somehow helpful to others too.
Thanks for the great and fast help!
Original post:
Good evening,
I am not completely sure if this topic is enough about programming but I am having some problems setting up Qtjambi. I have followed a lot of "howtos" and instructions so I am a little confused about what to do next. Qtjambi works as I have written a example program with netbeans. Although I have created some ui files that I want to implement which doesnt work.
I am trying to get this to run for like a week and I really need this because of my finals in 2 months. I try to give as much useful details as possible.
I am using LinuxMint (ubuntu derivate), downloaded qtjambi v 4.7.0
after trying out
bash qtjambi.sh
I got an error of mismatching versions
Cannot mix incompatible Qt library (version 0x40704) with this library (version 0x40700)
So I downloaded, compiled and installed
qt-everywhere-opensource-src-4.7.0 to /usr/local/Trolltech/Qt-4.7.0/
I know that I have to tell the system where to find all the binarys so I added to the /etc/bash.bashrc
#custom PATH exports
PATH=$PATH:/home/michi/Scripts
PATH=$PATH:/usr/local/Trolltech/Qt-4.7.0/bin/
export LD_LIBRARY_PATH=/usr/local/Trolltech/Qt-4.7.0/lib
export QT_PLUGIN_PATH=/usr/local/Trolltech/Qt-4.7.0/plugins
JAVA_DIR=/usr/lib/jvm/java-6-sun-1.6.0.26/
export JAMBI_PATH=/usr/local/lib/qtjambi-linux64-community-4.7.0/
I followed through the instructions of:
http://www.davidlauzon.net/2010/01/getting-started-with-qt-jambi-on-linux/
Which generally talks about getting jambi-designer to work.
http://jpnurmi.kapsi.fi/blog/2008/03/16/how-to-switch-qt-version-in-ubuntu/
How to manage multiple Qt versions.. These commands worked but had no effect
I finally gave up on trying to run the designer and tried to "convert" the .ui files to .jui files with the program juic which is located in the qtjambi/bin folder. But also here I get an error:
michi#BALMORA ~/Documents/unterlagen/pr_scw/Qt/Qtrainer/test $ which juic
/usr/local/bin/juic
michi#BALMORA ~/Documents/unterlagen/pr_scw/Qt/Qtrainer/test $ juic -cp .
juic: no .jui files found in CLASSPATH
michi#BALMORA ~/Documents/unterlagen/pr_scw/Qt/Qtrainer/test $ /usr/locallib/qtjambi-linux64-community-4.7.0/bin/juic -cp .
juic: no .jui files found in CLASSPATH
It would be great if you could help/guide or redirect me to "better" instructions.

I'm a total Java noob so please understand =) I need a quick advice on how to fix the issue.
I cloned the official selenium git repo, changed the code a bit (need to dump the page into some specified dirs), and tried to rebuilt it:
./go //java/server/src/org/openqa/selenium/remote/server:server:uber //java/client/src/org/openqa/selenium:client-combined:uber
It was successful but when I tried to execute it I got this:
$ java -jar build/java/server/src/org/openqa/selenium/remote/server/server-standalone.jar
Failed to load Main-Class manifest attribute from
build/java/server/src/org/openqa/selenium/remote/server/server-standalone.jar
Tried to check classpath, CLASS_PATH and CLASSPATH env variables (as a friend of mine suggested) - I simply don't have any.
At the same time, the pre-compiled standalone server from the official downloads works out of the box.
The official docs didn't help. There's nothing about it there.
So - I need a quick advice how to compile it? Thanks.
P.S. JDK 8 (latest), Mac OS 10.7
P.P.S. That friend of mine tried to build it by himself and he was lucky - he got a new build/dist folder where the target big file was. But in my case, the build folder is created, but there's not 'dist' folder in it.
Finally found the answer: I should have built it like that:
./go clean release
it's really strange that all the docs state I need to use these long /bla/bla/:uber things to get a whole single 'uber' server.
Update: The problem was solved with the help of MathWorks. I've published the answer below.
I need to control a program (Zemax) from Matlab. Unfortunately, Zemax only supports DDE for such control, which Matlab does not support any more. It works, but stops working on 64 bit platform after a few (presumable 63) DDE calls.
I wonder if there are working solutions. I could probably program a DLL with correct DDE support and then use DDE in Matlab via this DLL. This is a major effort for me. A more suitable solution would be to use Java DDE methods. Following another post here, I've discovered the JDDE library. However I cannot make it work: Even if I am in the directory with the DLL and JAR files, executing
import pretty-tools.JDDE-2.0.3.*
works fine but calling
a = com.pretty_tools.dde.client.DDEClientConversation()
afterwards (as done here) results in
Undefined variable "com" or class "com.pretty_tools.dde.client.DDEClientConversation".
I have very limited writing privileges on my PC, so I have added the javaclasspath.txt file with the jar/dll location to the directory indicated by prefdir. The file looks like this:
C:\Users\xxxxxxxx\Documents\matlab toolbox\jdde\pretty-tools-JDDE-2.0.3.jar
Calling javaclasspath shows a long listing with the last lines being:
...
C:\Program Files\MATLAB\R2012b\java\jarext\webservices\ws_client_core\mw-service-client-core.jar
C:\Users\kkarapet\Documents\matlab toolbox\jdde\pretty-tools-JDDE-2.0.3.jar
DYNAMIC JAVA PATH
<empty>
So path seems to be set correctly. What am I doing wrong?
With the help of MathWorks support, I've found the answer. Here is how to make JDDE work with Matlab 2012b, without admin privileges:
Download and unpack JDDE files (DLLs and JAR) into some folder. Let's say it's $path-to-jdde$\.
In Matlab, type prefdir. Open the resulting directory and create two files there, javaclasspath.txt and javalibrarypath.txt.
In javaclasspath.txt, add $path-to-jdde$\pretty-tools-JDDE-2.0.3.jar.
In javalibrarypath.txt, add $path-to-jdde$\.
Restart Matlab.
Now call ddeConv = com.pretty_tools.dde.client.DDEClientConversation; and start using the created object as described in JavaDoc. E.g. to connect to Zemax, run Zemax and then in call ddeConv.connect('Zemax', 'abc').
Step 2 above can only be done starting Matlab version R2012b. With an older version, if you have the write rights on the Matlab installation directory, you should be able to replace step 2 by editing the files librarypath.txt and classpath.txt in $MATLABROOT$\toolbox\local. I could not verify it so if you confirm it please let me know in the comment below.
I'm on Windows 7 32bit, Java JRE6 31 installed and using Sikuli X 1.0rc3. I want to launch a test with sikuli-script.jar like this:
java -jar c:\sikuli\sikuli-script.jar test.sikuli
All I get is this error message:
java.lang.UnsatisfiedLinkError: java.lang.UnsatisfiedLinkError:C:\sikuli\libs\VisionProxy.dll: Can't find dependent libraries
I have set all the environment variables needed, so my PATH looks like this:
PATH=...;C:\sikuli\libs;C:\Program Files\Java\jre6\bin
SIKULI_HOME=C:\sikuli
I can use the IDE and launch the tests there etc. But only if I use the Sikuli-IDE.exe the sikuli-ide.bat and sikuli-ide.jar don't work either. Always with the same error from above. So I think in the build process of the .exe file they added some magic, but I can't figure out what it is.
Does somebody have a similar problem? Or even a solution?
Update
As I wrote below, it works out of the box with my new computer. :D But maybe my solution can help someone.
Sikuli Team uses Launch4J to build the Sikuli-IDE.exe out of the sikuli-ide.jar. They use this config file. I modified it slightly and created a Sikuli-script.exe. It was pretty simple but I lost the config file unfortunately.
Hope I could help!
You must use a 32bit JRE version (I use jre-7u4-windows-i586.exe)
Download Sikuli IDE for Windows (I use "Sikuli X r930", portable version)
Unpack it and copy files to your project folder (I renamed it to "sikuli-ide", check image htt+p://i.stack.imgur.com/LSiQV.png)
Add sikuli-script.jar to the Referenced Libraries (Project > Properties > Java Build Path > Libraries, check image http://i.stack.imgur.com/N2SJ8.png)
Set PATH and SIKULI_HOME environment vars (Run > Run Configurations > Environment, check image http://i.stack.imgur.com/HboXk.png)
You're ready to go ;)
According to the docs
Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native.
What you need to do is use this command:
-Djava.library.path=pathToDLL
Which will add your DLL that is missing.
I'm using the code from this tutorial for using MXJ to "embed" MySQL in my java application. However, I'm getting this exception when running the code:
Exception in thread "main" java.util.MissingResourceException: Resource '5-5-9/Windows_7-amd64/mysqld.exe' not found
This happens when I reach this line in the tutorial:
mysqldResource.start("test-mysqld-thread", database_options);
I'm running in Eclipse and I have the 4 following jars added to my build path, since this link says I need them:
mysql-connector-java-5.1.18-bin.jar
mysql-connector-mxj-gpl-5-0-12-db-files.jar
mysql-connector-mxj-gpl-5-0-12.jar
aspectjrt-1.6.9.jar
I'm not sure what I'm missing here. Any tips?
MXJ doesn't come ready for use with Windows 7 64 bit. Using this bug ticket, I found what I needed to do.
Once the files are downloaded and extracted from the zips, unjar mysql-connector-mxj-gpl-5-0-12-db-files.jar and add a line to platform-map.properties file inside:
Windows_7-amd64=Win-x86
Save, and re-jar. Works like a charm!
Actually it's never a good idea to mess up with the jar files, cause whenever you upgrade to a newer version you'll need to remember to redo this fix again. The answer is correct, but you just need to create platform-map.properties file with this inside:
Windows_7-amd64=Win-x86
and add it to your classpath.
For anyone who has the same issue on MacOS Catalina, you can follow the README.md in my repo (https://github.com/pengyue/mysql-connector-mxj-mac-os-catalina), which has the 64 bits executables for MacOS Catalina, and this improved connector works on Catalina.
To explain what I have done:
Download the 64 bits executables from MySQL to the folder 5-5-9
Add the platform mapping for 64 bits MacOS in platform-map.properties
Create a jar by using jar cvf mysql-connector-mxj-db-files-5.0.12.jar .
Replace the jar in your mvn settings folder ~/.m2/repository/mysql/mysql-connector-mxj-db-files/5.0.12/ with the jar you just created.
This solution works fine for my projects, Unfortunately I could not find a github for the mysql-connector-mxj, as it is deprecated and not maintainable anymore.
The other option is to use wix-embedded-mysql(https://github.com/wix/wix-embedded-mysql) instead of mysql-connector-mxj, but this probably requires some code changes in your projects.
I'm trying to make a small GUI app and I want to use MigLayout with it.
As Java newbie I don't know how to get MigLayout to work with my code and I'm running out of ideas.
My project source code is in ~/git/project/src/qdb/
The qdb is my java package name. I downloaded miglayout-3.7-swing.jar and miglayout-3.7.jar and placed them to my project sources and tried to compile the code but I get errors pointing to "new MigLayout()" stating "cannot find symbol".
I was in src dir and used "javac qdb/*.java" to compile (* gets expanded).
I also tried to point classpath to my sources like: "javac -classpath /home/user/git/project/src/qdb/ qdb/*.java" but I still get the error.
Then I've also tried to put the jar files to ~/jars/ and use that as classpath but still the same error follows.
So, how to get MigLayout working?
Simply add the miglayout-3.7-swing.jar to your classpath:
javac -classpath /your/path/to/miglayout-3.7-swing.jar qdb/*.java
(as illustrating in this thread Installing Mig Layout)
If you can compile them (with the above line),
but can not execute the resulting program, you also need to add to the java classpath the library
java -classpath /your/path/to/miglayout-3.7-swing.jar:/your/project/compiledClass/dir qdb.yourMainClass
If you are going to put it into a .jar file, you'll need to specify the Class-Path in the manifest file:
Class-Path: /your/path/to/miglayout.jar
VonC's answer is right. I just want to add (since you are a Java newbie) that you should consider developing using an IDE. They'll save you hours of by-hand-compiling, and will help you integrate your code with libraries (such as MigLayout) more easily.
There are two free IDEs I really like:
IBM's Eclipse.
SUN's (soon to be IBM's) Netbeans.
Also consider this SO thread. And this one too.
Good luck.
