A weird java web service client error

When I developed web service client in Rational Application Developer, I got the below error:
Exception in thread "main" javax.xml.ws.WebServiceException: org.apache.axis2.AxisFault: WSWS7130E: No Secure Sockets Layer (SSL) configuration is available for the https://... endpoint.

After searching the google, got a useful article "Using Secure Web Services HTTPs (SSL)":
http://btarlton.blogspot.ca/2013/03/ever-have-trouble-using-ssl-to-call-web.html
So I exported the certificate and add the below to VM arguments:
-Djavax.net.ssl.trustStore=C:\temp\myTrustStore -Djavax.net.ssl.trustStorePassword=changeit
Then the error "No Secure Sockets Layer ... " is gone.
However, another error is raised: "java.io.IOException: Connection close: Read failed. Possible end of stream encountered. "

I searched a lot and tried some ways like setting com.ibm.websphere.webservices.http.requestResendEnabled but still got the error.

Finally I decided to regenerate the client from scratch using wsimport -keep, and copy them into RAD7.5, Phew, everything works perfect.

So what's the problem? I compared the two projects source code until they are all identical through WinMerge. But their behavior are still different.
Then I checked the projects setting in RAD and removed the auto introduced WAS_V7JAXWS_WEBSERVICES_THINCLIENT, now both of them works like a charm.

It's so misleading and confusing for the IDE especially if it involves IBM product. Under such case, should remove the dependency on IDE as much as possible
so that we can isolate the issue.

Scala SBT error: sun.security.validator.ValidatorException: PKIX path building failed

Environment:

Windows 7 in the company, no proxy

No installation on Scala SDK

When run "sbt" from command line, got the error:

sun.security.validator.ValidatorException: PKIX path building failed Error ...

The reason is that Java cannot access https website without trusted key store.

The below two articles explained very well and have the detailed solution, after put the key file to folder jre\lib\security, and rerun "sbt", the error is gone. (my concern, why "mvn" has no such error?)

mvn archetype:generate does not work-no plugin found

When run the below:

mvn archetype:generate

got the below error:


mvn archetype:generate does not work-no plugin found for prefix 'archetype'



add -X and search metadata.xml:

mvn -X archetype:generate



It cannot get the *metadata.xml from the central repository because of the firewall/certification

although from the web browser the link is accessible:

https://repo.maven.apache.org/



Two solutions:

1. add settings.xml in the mvn .m2 folder:

<settings>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>securecentral</activeProfile>
  </activeProfiles>
  <profiles>
    <profile>
      <id>securecentral</id>
      <!--Override the repository (and pluginRepository) "central" from the
         Maven Super POM -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://repo1.maven.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>central</id>
          <url>http://repo1.maven.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
</settings>


2. get and set the certificate file

健身

心肺能力的提高，靠的是长时间的低强度运动，俗称有氧运动，也就是长跑、游泳等。
我认识一个人，只做俯卧撑，一天做3种变式的俯卧撑，共12组，每组15个，胸肌腹肌分离度和形状都非常棒
【无氧运动的时间】如果是力量训练，实际上时间控制在1小时为最佳，因为男性在进行力量训练的时候，会分泌睾酮，但是睾酮在训练后半小时大幅减少，所以无氧锻炼是前半小时的效率是最高的，因此时间控制在30~60min最好。

蛋清可以多吃，蛋黄一天一个或者两个就够了

https://www.zhihu.com/question/20687290/answer/15853608
最简单的锻炼计划
1.慢跑3~5分钟。总之达到身体微微出汗或者发热的效果即可停止。
2.做仰卧起坐和俯卧撑。
3.然后出去跑5公里，两天或者三天一次。

要保证每天至少7小时的睡眠，让肌肉在睡眠中得到充分的增长。而且每块大肌肉（胸背肩腿）每周练到力竭不要超过两次，小肌肉（手臂、腹部）每周练到力竭不要超过三次。这样能够保证最好的增长。
