I want to start create mods and so on to minecraft. I am a javaprogrammer myself, so the coding shouldn't be a problem. but to start the programming I need to decompile the server file from minecraft. Everything to do so is given and explained in a txt document, but nontheless I still get an annoying error.
I have checked my pth for JDK and JRE, have the latest version of both and all.
I really hope someone can help me. Here's the traceback:
File "runtime\decompile.py", line 143, in <module> main()
File "runtime\decompile.py", line 143, in <module> main()

File "os.pyc", line 157, in makedirs
WindowsError: [Error 5] Access is denied: 'temp'
If I run as administrator I get following msg:
The system cannot find the path specified.
You'd safe my day if you could help me with this problem.
Which decompiler do you use? I'd start checking this commands.py line 530 for any clues what value does this dirtemp has. I'd recommend using the JD decompiler.
Also, I'd be surprised if Notch hadn't used any obfuscators to prevent decompiling. That means you'll get a bunch of unreadable gibberish Java sources.

I am trying to install Matlab on a Linux machine, but setting LD_LIBRARY_PATH (as the installation requires) breaks other library files. I am not an Linux expert, but I have tried several things and cannot get it working correctly. I have even contacted Matlab support, got the issue elevated to the dev team, and was basically told "haha sucks to suck". I have seen a few other people online have had the same issue, but either their questions were never answered or they had a slightly different problem and their solution didn't apply to me.
Installing on a VM running Ubuntu:
I set LD_LIBRARY_PATH as the instructions say, then it breaks network files. I can ping google.com, but I cannot nslookup google.com or visit it in a browser. Nslookup provides this error:
nslookup: /usr/local/MATLAB/MATLAB_Runtime/v90/bin/glnxa64/libcrypto.so.1.0.0: no version information available (required by /usr/lib/libdns.so.100)

(null): dst_lib_init: crypto failure
The installation worked though (I can run my Java programs that reference compiled Matlab functions). Unsetting LD_LIBRARY_PATH fixes the network files but then I can't run programs anymore.
Installing on EC2 instance:
On an EC2 instance it does not break the network files (nslookup is fine). Instead it messes up Python library files. Trying to use any aws cli command, I get the error:
File "/usr/bin/aws", line 19, in <module>

ImportError: PyCapsule_Import could not import module "pyexpat"
Printing sys.path in Python shows lib-dynload is already there though, so it doesn't seem to the problem.
And when trying to run the program, I get:
Exception in thread "main" java.lang.LinkageError: libXt.so.6: cannot open shared object file: No such file or directory

I'm at a brick wall and really have no clue how to proceed.
Maybe something else already needs LD_LIBRARY_PATH set to work. Make sure you prepend not overwrite:
export LD_LIBRARY_PATH=new/path:$LD_LIBRARY_PATH
Edit:
OK, if LD_LIBRARY_PATH was initially empty, this suggests that Matlab comes with shared libraries that are incompatible with your system ones:
nslookup: /usr/local/MATLAB/MATLAB_Runtime/v90/bin/glnxa64/libcrypto.so.1.0.0: no version information available (required by /usr/lib/libdns.so.100)
suggests that /usr/lib/libdns.so.100 needs libcrypto.so.1.0.0, which is now being resolved to the one that comes with MATLAB, which is incompatible.
You can check the dependencies of a dll by
ldd /usr/lib/libcrypto.so.1.0.0
and hopefully you can find a configuration that keeps both MATLAB and your system happy. Unfortunately, this may involve a lot of trial and error.
If there is no such configuration, you can try setting LD_LIBRARY_PATH only when you run MATLAB:
LD_LIBRARY_PATH=$MATLAB_LD_LIBRARY_PATH matlab
Edit 2:
Well, for the Python issue, it seems to boil down to pyexpat, which is a wrapper around the standard expat XML parser. Try doing (name guessed since I don't have a Linux right now):
ldd /usr/local/lib/python2.7/site-packages/libpyexpat.so
and see what that depends on. Probably, it will be libexpat.so, which is now being resolved to MATLAB's version.
try the following command:
export LD_LIBRARY_PATH=/usr/local/MATLAB/MATLAB_Runtime/v90/runtime/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v90/bin/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v90/sys/os/glnxa64:$LD_LIBRARY_PATH
Perhaps not helpful for OP but if you are generating a python package with MATLAB, you could modify the generated __init__.py file MATLAB creates for your package.
Specifically, the generated __init__.py file contains the following line (as of MATLAB 2017a):
PLATFORM_DICT = {'Windows': ['PATH','dll',''], 'Linux': ['LD_LIBRARY_PATH','so','libmw'], 'Darwin': ['DYMCR_LIBRARY_PATH','dylib','libmw']}
For Linux platform, you could simply replace LD_LIBRARY_PATH with something else such as MCR_LIBRARY_PATH to prevent mucking with your shared libs.
sed -i -e 's/LD_LIBRARY_PATH/MCR_LIBRARY_PATH/g' /MY/PACKAGE/BUILD/PATH/__init__.py
Then obviously export MCR_LIBRARY_PATH before using python.
So, here's my problem. I've got my ANTLR4 code successfully compiled, without errors and now I want to test it out. The ANTLR4 Documentation tells me, to test my applications, I shall do this:
java org.antlr.v4.runtime.misc.TestRig
I've tried this and got following error:
Error: Main Class org.antlr.v4.runtime.misc.TestRig couldn't be found or load.
I've checked if my CLASSPATH wasn't set, but everything was correctly set as it should be. I also tried moving the file directly to my test folder and opened CMD there and tried it again, I occur the same error. Searching in the Internet didn't help, as no one seemed to have occurred this error with ANTLR4 before.
Specs:
Java 1.7.0.55
ANTLR 4.4
There seems to be something wrong with your classpath, contrary to your belief everything is okay.
When I download the ANTLR 4 JAR and run TestRig:
wget http://www.antlr.org/download/antlr-4.4-complete.jar
...
java -cp antlr-4.4-complete.jar org.antlr.v4.runtime.misc.TestRig
I see the following on my console:
java org.antlr.v4.runtime.misc.TestRig GrammarName startRuleName
[-tokens] [-tree] [-gui] [-ps file.ps] [-encoding encodingname]
[-trace] [-diagnostics] [-SLL]
[input-filename(s)]
Use startRuleName='tokens' if GrammarName is a lexer grammar.
Omitting input-filename makes rig read from stdin.
After having spend 4 days on searching for a working solution, i guess i need to ask.
So far i'm successfully working withj jython 2.5.2 or 2.5.3, with a modifier thinClient.sh that loads what i need. It connects successfully to a DeploymentManager with either IPC or SOAP connector.
However it lacks the readline module:
wsadmin>import readline
WASX7015E: Exception running command: "import readline"; exception information:
com.ibm.bsf.BSFException: exception from Jython:
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/usr2/produits/websphere7/AppServer/thinClient/lib/jython/Lib/readline.py", line 20, in <module>
raise ImportError("Cannot access JLineConsole")
ImportError: Cannot access JLineConsole
The goal is to make it interactive, with colored prompt and sofort.
I tried so far with absolutely no success:
org.python.util.JLineConsole / org.python.util.ReadlineConsole (misses readline module)
Readline-1.7 (does nothing)
java-readline / libreadline-java-0.8.0 (misses readline module)
JLine (won't load the jar)
pyreadline (won't integrate to jython)
So:
is it possible with jython 2.5.3 under IBM AIX 64, with a thinClient (jython-installer-2.5.3.jar) to have a real interactive shell with bash like completion and command recall using arrow keys, without having to build/compile something ?
if yes, please somebody describe a working solution:
what's the solution name ?
what's in your wsadmin.properties ?
which libraries to load in LIBPATH ?
which class to load in CLASSPATH ?
which command line to invoque with java ?
There are so many "solutions" or "propositions" to this frenquently asked question on the web, but nowhere did i found a well described or working solution. Too much information scattered all around just becomes a mess :(
thanks for any help !
ok i found a workaround, that was so easy to answer myself:
rlwrap -H $THIN_CLIENT_HOME/logs/rlwrap.history.log -f $THIN_CLIENT_HOME/etc/rlwrap.jython.words.txt -r -pBlue -z $THIN_CLIENT_HOME/etc/rlwrap.prompt.pl $CMDLINE
org.python.util.* and com.ibm.ws.scripting.WasxShell are mutually incompatible
I have an AVRO file(created by JAVA) and seems like it is some kind of zipped file for hadoop/mapreduce, i want to 'unzip' (deserialize) it to a flat file. Per record per row.
I learned that there is an AVRO package for python, and I installed it correctly. And run the example to read the AVRO file. However, it came up with the errors below and I am wondering what is going on reading the simplest example? Can anyone help me interpret the errors bellow.
>>> reader = DataFileReader(open("/tmp/Stock_20130812104524.avro", "r"), DatumReader())
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/.../python2.7/site-packages/avro/datafile.py", line 240, in __init__
raise DataFileException('Unknown codec: %s.' % self.codec)
avro.datafile.DataFileException: Unknown codec: snappy.
btw, if I do 'head' of file, and using VI to open up the first few lines of the AVRO file, I could see the schema definition together with some crappy weird characters - probably the zipped content.
The starting bit of the raw AVRO file looks like below:
bj^A^D^Tavro.codec^Lsnappy^Vavro.schemaØ${"type":"record","name":"Stoc...
I don't know if those schemas would be necessary to read the AVRO file, something like below:
schema = avro.schema.parse(open("schema").read())
# include schema to do sth...
reader = DataFileReader(open("Stock_20130812104524.avro", "r"), DatumReader())
Thanks in advance.
Try pip install python-snappy - make sure you have installed snappy first.
The problem is that if there is no Xcode command line tools installed you cannot get snappy working. You can check by typing gcc at the command prompt to see if it is installed or not. If not then type xcode-select –-install to install it. Then installing python-snappy should work. Thanks Bin!
wget http://www.us.apache.org/dist/avro/avro-1.7.5/java/avro-tools-1.7.5.jar

I just started using Octave, and have been trying to do some operations from data in Excel files. I've installed the IO, Java, and Windows packages in Octave, but when I run the script, I get the following error message:
Looking for supported interfaces:
Excel/COM... not working.
error: No Java support found.
error: called from:

I've been trying to solve this for a little while now so any help would be greatly appreciated!
The first error is
No Java support found.
So it's probably because you have not properly installed the java package.
Read and follow the instructions under the section How to install the java package in Octave? in the documentation.
There is also a document called: How to install the java package in Octave? that can be helpful.
