Report only compiles on Console

[Siwakhile]

Im only able to compile on linux shell,

on browser/apache I get

Fatal error: Uncaught PHPJasper\Exception\ErrorCommandExecutable: Your report has an error and couldn 't be processed!\ Try to output the command using the function output(); and run it manually in the console. in /var/www/html/Siphile/admin/vendor/geekcom/phpjasper/src/PHPJasper.php:236 Stack trace: #0 /var/www/html/Siphile/admin/reporttest.php(9): PHPJasper\PHPJasper->execute() #1 {main} thrown in /var/www/html/Siphile/admin/vendor/geekcom/phpjasper/src/PHPJasper.php on line 23

Hi @Siwakhile please try to output the command using the function output(); and run it manually in the console.

Usually this happens because the jasperstarter in linux needs execution setup. Do this sudo chmod +777 jasperstarter and sudo chmod +x jasperstarter

Hello,

I have the same problem. I see what's happening.

My console output its like:

./jasperstarter process "/var/www/html/....

If I execute in the command line I need to remove the innitial dot slash to execute the commnad.

Debugging the code at line 87 in PHPJasper file of the package I see this function:

private function checkServer()
{
        return $this->command = $this->windows ? $this->executable : './' . $this->executable;
}

If I remove './' . the next code works well

    $jasper = new PHPJasper;
        $jasper->process(
        $input,
        $output,
        $options
    )->execute();

Why the dot slash is necessary or not? Depends on the linux flavor?

Why the dot slash is necessary or not? Depends on the linux flavor? On linux it´s mandatory ./ (dot slash) to execute de jasperstarter command. On windows japerstarter.exe ...... to execute

Hi, but I'm on a Linux Docker and it's not working with the dot-slash. Any ideas why?

[josevillasmil]

try sh command, maybe, i am not sure

Hi, I found the problem and a solution.

I make an in depth debugging and catch the stderror and I get this error

Exception in thread "main" java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap') at de.cenote.tools.classpath.ApplicationClasspath.add(ApplicationClasspath.java:75) at de.cenote.tools.classpath.ApplicationClasspath.add(ApplicationClasspath.java:65) at de.cenote.tools.classpath.ApplicationClasspath.addJars(ApplicationClasspath.java:134) at de.cenote.tools.classpath.ApplicationClasspath.addJarsRelative(ApplicationClasspath.java:151) at de.cenote.jasperstarter.App.processReport(App.java:178) at de.cenote.jasperstarter.App.main(App.java:109)

I found that this is an error reported before in https://github.com/PHPJasper/phpjasper/issues/152

I have installed openjdk 11. Following the suggestions from some users I change java to version 1.8 following this steps.

I download the jdk following the instructions in this link

https://lv.binarybabel.org/catalog/java/jdk8

I execute in my home root

wget --no-check-certificate --no-cookies --header 'Cookie: oraclelicense=accept-securebackup-cookie' ' http://download.oracle.com/otn-pub/java/jdk/8u251-b08/3d5a2bb8f8d4428bbe94aed7ec7ae784/jdk-8u251-linux-x64.tar.gz'

Or download from https://www.oracle.com/java/technologies/javase-jdk8-downloads.html

After download execute this commands adapting these commands to your server or installation:

mkdir -p /usr/java

mv jdk-8u251-linux-x64.tar.gz /usr/java

cd /usr/java

tar zxvf  jdk-8u251-linux-x64.tar.gz

rm jdk-8u251-linux-x64.tar.gz

cd /usr/java/jdk1.8.0_251/bin

 ./java -version

After that the java version installed in this directory must be:

java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)

Now configure this new Java package as the default one following the instructions on this link

https://www.javahelps.com/2015/03/install-oracle-jdk-in-ubuntu.html

So I add to the /etc/environment

nano /etc/environment

this lines

PATH=$PATH:/usr/java/jdk1.8.0_251/bin:/usr/java/jdk1.8.0_251/db/bin:/usr/java/jdk1.8.0_251/jre/bin
J2SDKDIR="/usr/java/jdk1.8.0_251/bin"
J2REDIR="/usr/java/jdk1.8.0_251/db/bin"
JAVA_HOME="/usr/java/jdk1.8.0_251/jre/bin"

and configure the new installed java jdk executing this commands

 update-alternatives --install "/usr/bin/java" "java" "/usr/java/jdk1.8.0_251/bin/java" 0

 update-alternatives --install "/usr/bin/javac" "javac" "/usr/java/jdk1.8.0_251/bin/javac" 0

 update-alternatives --set java /usr/java/jdk1.8.0_251/bin/java

 update-alternatives --set javac /usr/java/jdk1.8.0_251/bin/javac

After this you can see the new configured java jdk executing:

update-alternatives --list java

update-alternatives --list javac

After that, all is working well.

Best regards

[josevillasmil]

Okey, congratulations, i am happy for you, and thanks for share and comment the solution for everyone. Best regards.
