Hello,

A custom action launch some commands on the system (transformation picture, detection of barcode). All was working great on Alfresco 32r2, 3.3g on Windows and Linux but I try to use it on 3.4d Linux RHEL and I get problems… (all is ok with 34d on Windows).

In my code
…
Process proc = Runtime.getRuntime().exec(commands);
…‍‍‍
Content of the variables commands

[/bin/sh, -c, convert -density 125 -threshold 46% "/opt/Alfresco/tomcat/temp/Alfresco/ReadBarcodesSplit1499126559/1_splitted.pdf" +adjoin "/opt/Alfresco/tomcat/temp/Alfresco/ReadBarcodesSplit1499126559/1_splitted.pdf_B.gif"]‍‍

The same command is working great on the server…

Are there something change to use Runtime.getRuntime().exec with the 3.4d ? Perhaps new version of Tomcat…

Thank you

I have done other tests. If I execute on the server or from a Java software, all is ok. I think the problem come from Tomcat.

Command on the server : OK

The code which was working in 33g doesn't work in 34d. I thought a problem with tomcat 33g-> 6.0.18 and 34d->6.0.26.
I have replace the directory  /opt/Alfresco/tomcat/conf from the 34d with 33g but there always the problem.

Where can be the difference using "Runtime.getRuntime().exec" between the 33g and 34d with Linux?

Thank you.

All is ok now…

Run the Alfresco convert from the Server
ImageMagick need some variables… Write in the command line

export MAGICK_HOME=/opt/Alfresco/common 
export DYLD_LIBRARY_PATH=/opt/Alfresco/common/lib
export LD_LIBRARY_PATH=/opt/Alfresco/common/lib
convert …
‍‍‍‍‍‍

Run the Alfresco convert from Alfresco
If your code start convert. Just set the variables

String[] processProperties = new String[] {
      "MAGICK_HOME=/opt/Alfresco/common",
      "DYLD_LIBRARY_PATH=/opt/Alfresco/common/lib",
      "LD_LIBRARY_PATH=/opt/Alfresco/common/lib"};
Process process = Runtime.getRuntime().exec(commandToExecute, processProperties);
