Java Spire.Doc Memory Settings

[cjericho]

Hi,

What is the required and recommended memory allocation (heap size) when using the Java Spire.Doc package.

I am consistently getting the below error when generating hundreds of documents using the package.

I am close to purchasing this software but this issue is making me doubt it. Can you please help?

Code: Select all

Exception in thread "pool-1-thread-109" java.lang.OutOfMemoryError: Java heap space

Hi,

Thanks for your inquiry.
Memory consumption is related to your documents, operation code and JVM configuration. If you were not using the latest version (Spire.Doc for Java 5.3.16), I suggest you download the latest one for testing, and configure a larger JVM memory such as -Xmx4g. If the "OutOfMemoryError" still exists, please provide detailed information as below to help us better investigate your issue. You can attach your file here or send it to us via email (support@e-iceblue.com). Thank you in advance.
1) Your input documents and the runnable code that can reproduce your issue.
2) Your test environment, such as OS info (Win10, 64bit, 8GB).
3) JDK version and JVM configuration.

Sincerely,
Kylie

Hi,

We have since purchased a license but the problem still exists.

The application we have is multithreaded, does Java Spire.Doc support multithreading?

Could there be a memory leak somewhere in the library?

2) Windows 10, 64-bit, 8GB
3) * openjdk 11.0.13 2021-10-19 * java -Xms2048m -Xmx4096m

Hi,

Thank you for your reply.
Spire.Doc supports creating Word documents in multi-thread. I did an initial test with the same environment as your, but still didn't encounter your issue. To help us investigate the problem and help you out quickly, please provide your full test code as well as your input documents(if any). You can attach them here or send to us via email (support@e-iceblue.com).
Sorry we did not find your purchase information according to your email. Could you please provide the authorized email address or order number for our reference? Thank you in advance.

Sincerely,

Hi,

You are correct the authorised email address is different from my email address. The order number is 11093 and was purchased on 2022-04-07.

I have created a test project that resembles very closely what we are trying to do.

Code:

Project.zip

Template:
Project\app\src\main\resources\template-v1.1.docx

Hi,

Thank you for your patience.
We are pleased to inform you that we have released a new version that addresses your SPIREDOC-7754 problem. Please download the new version from the link below.
Download from Website: https://www.e-iceblue.com/Download/doc-for-java.html
If you downloaded from the Maven repository, please change the pom setting to:
<repositories>
<repository>
<id>com.e-iceblue</id>
<url>https://repo.e-iceblue.com/repository/maven-public/</url>
</repository>
</repositories>

<dependencies>
<dependency>
<groupId> e-iceblue </groupId>
<artifactId>spire.doc</artifactId>
<version>10.6.0</version>
</dependency>
</dependencies>

In addition, since java memory is limited. When thousands of documents are running at the same time, memory consumption will be too large. So I suggested you should use thread pools to manage thread tasks to avoid overflow. Please refer to the code below.

Code: Select all

public static void main(String[] args) {
    ExecutorService executorService= Executors.newFixedThreadPool(10);
    for(int i=0;i<1000;i++){
        Future future = executorService.submit(new MyRun(i));
        try {
            future. get ();
        } catch (InterruptedException e){
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }
    }
    executorService.shutdown();
}
static class MyRun implements Runnable{
    private int _Index;
    public MyRun(int index){ this. _Index= index; }
    @Override
    public void run() {
        Document document = new Document();
        document.loadFromFile(inputFile,FileFormat.Docx);
        document.setUseNewEngine(true);
        document.saveToFile(output + _Index +".pdf",FileFormat.PDF);
        document.dispose();
    }
}
