运行IBMJDK7的wso2bam 2.4.0

Question

我正在尝试将wso2bam-2.3.0配置为在IBM1.7JDK上运行，以便可以从wso2am-1.6.0实例收集统计信息。产品文档表明IBM是受支持的，但是在按照集成设置步骤让api管理器和bam彼此对话之后，我在启动bam时得到一个异常。

对于基本wso2bam安装，也会发生同样的例外。我在for version 2.0 M5 (http://wso2.com/mailarchive/carbon-jira/2012-June/051761.html)中找到了对此问题的参考，但是没有找到V2.4.0的可行解决方案。这个问题似乎与Sun JDK对SunX509算法的依赖非常紧密。是否有人有解决此问题的解决方法/修复方法，或者知道如何配置BAM来解决此问题。

Answer 1

BAM 2.4.0似乎不支持IBM JDK。

根据BAM-502的说法，解决方案是升级thrift版本。然而，BAM 2.4.0仍然使用thrift 0.7.0。BAM中的节约包是wso2bam-2.4.0/repository/components/plugins目录中的libthrift_0.7.0.wso2v2.jar。

我提高了JIRA的优先权。因此，BAM团队可能会考虑在下一个版本中升级thrift版本。

最简单的解决方法是使用Oracle JDK 7。但是，我不确定这对您是否可行。

下一个解决方法是修补WSO2 BAM 2.4.0中的thrift版本。它似乎是一个简单的fix。应将TSSLTransportFactory更新为使用默认算法，如下所示。

protected String keyManagerType = KeyManagerFactory.getDefaultAlgorithm();
protected String trustManagerType = TrustManagerFactory.getDefaultAlgorithm();

然而，打补丁可能并不容易。如果确实需要在IBM JDK 7上运行BAM 2.4.0，可以尝试一下。

您需要签出thrift 0.7.0源代码并对其进行修补。打完补丁后，您可以构建libthrift_0.7.0.wso2v2.jar并将其作为patch复制到BAM2.4.0。

我希望这能帮到你。

谢谢!
