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?

try sh command, maybe, i am not sure El sáb., 18 abr. 2020 a las 10:28, Jose Juan Calvo (< notifications@github.com>) escribió:

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
#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

Okey, congratulations, i am happy for you, and thanks for share and comment the solution for everyone. Best regards. El dom., 19 abr. 2020 a las 8:18, Jose Juan Calvo (<notifications@github.com>) escribió:

Hello,

I need to migrate our legacy application from java8 to java17. While running the application, I encountered the following exception with OpenJDK 17. This worked fine with Java 8, but the new class loader mechanism under the module system is causing issues. What should be the solution for this?
java -version
openjdk version "17.0.11" 2024-04-16
OpenJDK Runtime Environment Temurin-17.0.11+9 (build 17.0.11+9)
OpenJDK 64-Bit Server VM Temurin-17.0.11+9 (build 17.0.11+9, mixed mode, sharing)

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 sentinel.command.SentinelBoot.addToClassPath(SentinelBoot.java:194)
at sentinel.command.SentinelBoot.initClassPath(SentinelBoot.java:63)
at sentinel.command.SentinelStarter.initStarter(SentinelStarter.java:54)
at sentinel.command.TrkServer.main(TrkServer.java:48)

Sharing few code snippets for reference:
URLClassLoader sysloader = (URLClassLoader)ClassLoader.getSystemClassLoader();
Class sysclass = URLClassLoader.class;
Method method = sysclass.getDeclaredMethod("addURL", parameters);
method.setAccessible(true);
method.invoke(sysloader, new Object[]{u});

I am stuck for so many days, nowhere getting any solutions. Please guide me. Thanks in advance!
