I'm trying to use R to hook the Java code from the GSRad project. The GSRad Java code is available online and comes as a One-Jar project jar (I was not familiar with One-Jar until today). I can run the One-Jar file just dandy using the following command (after unzipping the file from the above link):
java -jar gsrad_sample.jar
When I pop open the gsrad_sample.jar file I see a jar titled clima_GSRAD-1.0.0.jar in the /lib/ directory which contains the class files I want to hook with R. I've pulled out the jar of my affection and tried the following, to no avail:
library(rJava)
.jinit()
.jaddClassPath( "/home/jal/Documents/DSSAT/gsrad/clima_GSRAD-1.0.0.jar" )
.jnew( "cra/clima/gsrad/GSRBristowCampbellStrategy" )
Any tips on how I might hook the classes inside the clima_GSRAD-1.0.0.jar? I'm flummoxed.
EDIT
The GSRad site requires registration which is annoying. The full zip file which contains the Doxygen documentation for the Java package as well as the One-Jar jar file is available here and if you pop that open the jar that has the classes I want to hook is this one.
Let me preface my answer by saying that I'm no expert in Java / rJava, so apologies if this isn't 100% correct. I hope it's a step in the right direction though.
Start by unzipping gsrad_sample.jar to C:/gsrad (or adjust your paths based on where you unzip it). Then add all the contents of C:/gsrad/lib to your class path:
library(rJava)
.jinit()
.jaddClassPath(dir( "C:/gsrad/lib", full.names=TRUE ))
.jclassPath()
.jnew( "cra/clima/gsrad/GSRBristowCampbellStrategy" )

Actually, I'm trying to add new language to Streama Media Server. I downloaded source code, added new language file (as guided here). After that, I want to build a jar with that project, I build it with IntelliJ Idea 2021.1 (here is how I did). So, When I run that jar file (in Ubunt 20.04), it fails and gives this error: Screenshot
When you have made adjustments to the source code, it is likely that you will want to create a new .jar file and deploy it on your server. For this, you can use a simple command:
# for unix based systems
**./gradlew assemble**
# for windows
**./gradlew.bat assemble**
This will create 2 new .jar files under build/libs,
streama-{version}.jar
streama-{version}.jar.original
all you will need is the streama-{version}.jar.
This file is an executable, so you can just copy it into your deployment directory / your server and start it as usual.
Question : How do I make tools::testInstalledPackage work when I have a custom lib path defined in Rprofile.site.
I'm not an experience unix user so I might be wrong about this. Theres a line in tools::testInstalledPackage (shown below) which I suppose runs R in vanilla mode, i.e. my custom lib path in Rprofile.site does not get added in.
cmd <- paste(shQuote(file.path(R.home("bin"), "R")),
"CMD BATCH --vanilla --no-timing", Ropts, shQuote(Rfile),
shQuote(failfile))
In this case, when I try to test the package zoo, tools::testInstalledPackage returns a zoo-Ex.Rout.fail file with an error saying that there is no package called 'zoo' which makes sense as vanilla R does not contain my custom Lib folder.
Is there a way to use tools::testInstalledPackage to test my packages in my custom folder? Or do I have to copy the folder into the default file path
p.s. my current workaround is to create a new function without the --vanilla and attach it to the tools namespace but I don't think its a very elegant solution.
I am porting AXIS 2 SOAP webservice to an existing grails 2.4.4 project.
It works flawlessly when run from the IDE but not fram a WAR.
I have tracked this down to addresing.mar NOT being copied to the WEB-INF lib directory. If I copy this file myself then ever thing works fine.
We are using Jenkins for CI and using the Grails plugin to do the compilation of and packaging of the WAR file.
This does not include the addresing.mar file. Also when running the Grails war command it is not included.
I have tried many way to get this to be included. The AXIS plug in just wrecks the compile to teh extent that it is unusable.
I have just spent 2 days googling and tried ever thing I can find in just about every combination.
We are now getting to the point we we are considering post processing the war file and adding the addresing.mar file directly.
Though that will work it would not help my understanding of what I am doing wrong!
Any help most appreciated.
Try saving your file inside the /src file. Grails autowires external libraries when saved inside this folder.
Note: This is only applicable to Grails versions running less than 3.x.x
I don't know too much about AXIS 2 SOAP and the mentioned addressing.mar file but if it's available in the project while building the war file you could use the grails.war.resources parameter in BuildConfig.groovy and simply copy it into the lib directory in the following way:
grails.war.resources = { stagingDir, args ->
copy(file: "path/to/addressing.mar", todir: "${stagingDir}/WEB-INF/lib/")
}
more info about grails.war.resources in the manual
I am using iexpress to make my .jar files into .exe files
for this I add the jar file(myjarfile.jar) and in run command box I type : java -jar myjarfile.jar
but after creating the .exe the cmd that is flashing says cannot find the jar file myjarfile.jar
can any body help me find what I am doing wrong
To test this, I built a simple HelloWorld.jar file (using these instructions) and tested it like so:
java -jar HelloWorld.jar
Then I made an IExpress package with it. The Install program was exactly the command I used above. This worked exactly as it should.
Two possible causes of the error:
In the IExpress wizard, there's a checkbox Store files using Long File Name inside Package. You should definitely select this option; ignore the warning that appears, as it applies to Windows 95/98. In the .sed file, this is:
UseLongFileName=1
Check that the .exe actually contains myjarfile.jar. 7-Zip will open the .exe and show you the archive contents. (IExpress .exe files are just a CAB file with a wrapper.) If the file is missing, then you'll need to check your .sed file to see what went wrong.
I have a bunch of JAR files (from a maven2 project) and maven reports some package could not be found (org.openanzo.client.jena to be exact). I want to dig into the JAR files downloaded as the result of maven dependency resolution and find what packages are thus available from these JAR files. Insights?
UPDATE: Apparently, the only good solution to inspect insides of a jar file is the "jar" utility or one can use the facilities of their IDE to do so.
jar tvf filename.jar will show you the contents of a jar file without requiring you to extract it.
But I think that maybe what you are really trying to do is find the right coordinates for the dependency that you are missing, since obviously none of the ones you have right now are supplying the package you are looking for (in other words, checking their contents is not likely to help you).
I confess that the first place I would suggest to check is Sonatype's public Nexus instance. A search for your example turns up nothing, though. Usually that means the project is not trying to get their stuff into Maven Central or other major repositories (which is okay), so you have to resort to a web search. Usually the first two sections of the package tell you where to look (openanzo.org in your case).
If you are on Linux or a Mac, you could go to the terminal at the root of the folder containing your JARs and type:
# grep -ri "org.openanzo.client.jena" *
It will return a recursive list of all JAR files that contain that package name. If it returns 0 results, then none of those JARS contain that package.
If you wanted to do a more exhaustive search, you could unJAR the JAR files. The directory structure and .class files will be organized by packages in folders.
# jar xvf filename.jar
If you are on Windows, you can unJAR a JAR file using a tool such as 7Zip.
#Carsten
you do not have to rename a .jar file to .zip. You can directly open the jar file in winzip/or other zip utility (assuming windows OS)
#ashy_32bit
try using "jar class finder" eclipse plugin from IBM. Simple plugin for finding classes (if you know the class name)
OR
as carsten suggested... set the jar files as lib files and manually look it up
OR
create a batch file called a.bat (where you have all your jar files directly under a single folder) and paste the following 4 lines
#ECHO OFF
dir /b *.jar > allJarFilesList.txt
FOR /F %%A IN (allJarFilesList.txt) DO jar -tf %%A > list_of_packages.txt
FOR %%B IN (list_of_packages.txt) DO FIND /I "com/sun" %%B
NOTE the "com/sun" in the last line.. it is hard coded, you can pass as argument as well...
I know this is very basic form and can be improved "a lot" like looking up in various sub directories.
hope this helps :-)
.jar files are just ZIP compressed archives, rename it to zip, open it with your favourite unzip programm, and traverse through the directory.
If you add the jar file to a eclipse project, you can traverse through the lib in th project explorer.
HTH
Assuming maven downloaded the jar files,the files will be loaded in to a local repository.
You could use maven browser that comes packaged with Eclipse to browse and search for artifacts in your repository.(usually in userdir/.m2/repository)
Note:You can explore your repository directly if you want. You will understand the packages that were downloaded. But I suggest using the plugin.
If you are using Intellij IDEA, each project contains a tree called External Library that allows you to search and explore your libraries.
