Urgent - Error deploying .BAR file, why?

[sergiofigueras_]

Hi everyone,

When I deploy my .BAR file in activiti-explorer, everything goes fine. But when I try to deploy on my application, I'm getting this error:

I'm using those dependencies in my pom.xml:

      <dependency>
         <groupId>org.activiti</groupId>
         <artifactId>activiti-engine</artifactId>
         <version>5.10</version>
      </dependency>
      
      <dependency>

         <artifactId>activiti-spring</artifactId>
         <version>5.10</version>
      </dependency>
‍‍‍‍‍‍‍‍‍‍‍‍‍

And configuring in my applicationContext with:

<bean id="dataSourceBean"
      class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
      <property name="driverClass" value="#{props.bpmjdbcdriver}" />
      <property name="url" value="#{props.bpmjdbcurl}" />

My code to deploy is very simple:

   public void deployProcessBar(String fileName, byte [] barBytes) throws ExecutionException {
      DeploymentBuilder deploymentBuilder = repositoryService.createDeployment().name(fileName);
      InputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
      ZipInputStream zipInputStream = new ZipInputStream(byteArrayInputStream);
      deploymentBuilder.addZipInputStream(zipInputStream).deploy();
      try {
         byteArrayInputStream.close();
      } catch (IOException e) {
         throw new ExecutionException(e);
      }
   }
‍‍‍‍‍‍‍‍‍‍‍‍‍

The file name and BAR bytes are fine, I just don't know what I'm doing wrong. Another point is there's NO other reference to Xerces in my project.

Hi folks,

I've verified and in my workspace exists two classes named XMLSchemaLoader. One inside java-6-openjdk, in the package com.sun.org.apache.xerces.internal.impl.xs, and other inside XercesImpl-2.0.2, in the package org.apache.xerces.impl.xs, that one is being used with Activiti. There's no other class or Xerces package.

Any idea?

Is there a specific reason for using OpenJDK 6?
Could you try and use the Oracle JDK just to see if that solves the issue?

Best regards,

[sergiofigueras_]

Hi trademak,

I've changed the runtime environment to Oracle JDK 1.6.0u35, but the same error has occurred.

Just to remember: I'm using the Activiti code to deploy.

protected void deployUploadedFile() {
    DeploymentBuilder deploymentBuilder = repositoryService.createDeployment().name(fileName);
    try {
      try {
        if (fileName.endsWith(".bpmn20.xml")) {
          validFile = true;
          deployment = deploymentBuilder
            .addInputStream(fileName, new ByteArrayInputStream(outputStream.toByteArray()))
            .deploy();
        } else if (fileName.endsWith(".bar") || fileName.endsWith(".zip")) {
          validFile = true;
          deployment = deploymentBuilder
            .addZipInputStream(new ZipInputStream(new ByteArrayInputStream(outputStream.toByteArray())))
            .deploy();
        } else {
          notificationManager.showErrorNotification("deployment.upload.invalid.file",
            MessagesUtility.getMessage("deployment.upload.invalid.desc"));
        }
      } catch (ActivitiException e) {
        String errorMsg = e.getMessage().replace(System.getProperty("line.separator"), "<br/>");
        notificationManager.showErrorNotification("deployment.upload.failed", errorMsg);
      }
    } finally {
      if (outputStream != null) {
        try {
          outputStream.close();
        } catch (IOException e) {
          notificationManager.showErrorNotification("Server-side error", e.getMessage());
        }
      }
    }
  }

Phew … I'm almost out of options.

Is it possible to put your bar file somewhere online (or a bar file that fails, at least), so we can test it ourselves?

[sergiofigueras_]

Hi jbarrez,

Thanks for your patience. I've discovered the problem. I was using commons-dbcp 1.2.1 , but it's not supported. Then, I changed to 1.4 version and everything is going fine now.

Thanks!

[jbarrez]

Okay, that is a really strange solution … would never have expected the connection pool to be the culprit….

Thanks for posting back!
